As shown in fig. 2, the liquid supply assembly 200 may be used to provide a corresponding liquid to the mixing device 300. The mixing device 300 may control the output flow rate of the liquid, for example, reduce the output flow rate of the liquid, and may mix or homogenize the liquid. The mixing device 300 may output the cleaning liquid to the cleaning assembly 20, so that the cleaning assembly 20 may perform a cleaning process on an area to be cleaned using the cleaning liquid. The stain adsorption assembly 400 may adsorb garbage of the area to be cleaned, waste water generated during the cleaning, and the like during the cleaning of the area to be cleaned by the cleaning assembly 20.

As shown in fig. 2 and 3, the liquid supply assembly 200 may include a first water pump 210, a second water pump 220, a first liquid container 230, and a second liquid container 240. The first liquid container 230 is used for containing a first liquid, and the second liquid container 240 is used for containing a second liquid.

The blower 420 may also be connected to the cleaning assembly 20 through a corresponding pipeline to adsorb waste water generated during the cleaning process of the cleaning assembly 20 on the area to be cleaned and dirt such as garbage on the area to be cleaned. Stains such as waste water and garbage are introduced into the sewage container 410 by suction of the blower 420. The contaminated water container 410 may wash the air flow, and the washed air flow is discharged to the outside of the accommodating sub-housing 110. The dirty water container 410 may also be provided with a vent filter plate 411 to enable the washed air stream to flow out of the vent filter plate 411. The vent filter plate 411 is also shown in fig. 2 and 3. Alternatively, the blower 420 may be provided to the cleaning assembly 20, and the blower 420 and the sewage container 410 may be communicated through corresponding pipes.

As shown in fig. 5, the cleaning assembly 20 may include a housing 201, a roller brush 202, and a motor 203. Fig. 6 exemplarily illustrates a partially schematic structure in a cross section of a section line A-A for illustrating a simple positional relationship of the roller brush 202, the accommodation space 2011, the injection port 2012, and the suction port 2013, and other components are omitted and not shown. As shown in fig. 6, the housing 201 may be opened with a receiving space 2011, an injection port 2012 communicating with the receiving space 2011, and a suction port 2013. The rolling brush 202 is rotatably disposed in the accommodating space 2011. A motor 203 may be fixed to the housing 201 for driving the rolling brush 202 to rotate. The roller brush 202 may be used to contact the area to be cleaned and thereby wipe the area to be cleaned in a rolling friction manner. The number of the roller brushes 202 may be one or more. In many cases, a plurality of roller brushes 202 may be disposed in a side-by-side spaced relationship. The mixing device 300 may be communicated to the injection ports 2012 by respective pipes to inject the cleaning liquid through the injection ports 2012. The suction port 2013 may be connected to the blower 420 through a corresponding pipe, and thus suck the garbage of the area to be cleaned, sewage generated during the cleaning process, and the like into the sewage container 410.

Alternatively, as shown in fig. 6, the injection ports 2012 may be provided toward the roller brush 202 to inject the cleaning liquid toward the roller brush 202 so that the roller brush 202 is wet, and thus the roller brush 202 may wet clean the area to be cleaned. Alternatively, the injection port 2012 may be disposed outside the opening of the accommodating space 2011, so as to directly inject the cleaning liquid to the cleaning area.

Of course, the cleaning liquid may be sprayed in the form of steam, and the mixing device 300 may then be provided with a steam generator (not shown) for evaporating the cleaning liquid output from the mixing device 300 into steam and spraying the steam through the spraying port 2012. The water vapor can be sprayed to the roller brush 202 or to the area to be cleaned through the spray ports 2012.

As a result of long-term studies by the present inventors, it was found that the flow rate of the liquid to be outputted may be different depending on conditions such as a use scene during use of the cleaning apparatus 1. For the working condition of smaller flow, the pump body with smaller flow can be used, and speed regulation can be realized by adjusting the working frequency, the working voltage and the like of the pump body, so that the output flow of liquid is reduced. However, the operating frequency and operating voltage cannot be reduced infinitely, which can cause the drive motor 203 to operate outside a reasonable operating range, causing additional heating, and even failing to start up properly. If the required flow is far smaller than the rated flow of the minimum pump body in the market, the problem of small flow is difficult to solve. In addition, a speed reducing mechanism can be added at the output end of the driving machine, so that the output rotating speed is greatly reduced, the driving machine can still work in a reasonable rotating speed interval, but the driving machine is necessary to increase additional efficiency loss because of the newly introduced speed reducing mechanism, and the speed reducing mechanism is necessary to be matched with a heat radiating mechanism to offset the additional heat caused by the efficiency loss.

For the above-mentioned problem of reducing the output flow rate of the liquid, the mixing device 300 of the present embodiment can control the output flow rate of the first liquid. For the content of the mixing device 300 of the present embodiment, reference may be made to the following description of an embodiment of the mixing device 300 of the present application.

As shown in fig. 7, the mixing device 300 may include a liquid flow regulating assembly 301 and a mixing tube 302. The liquid flow regulating assembly 301 may be in communication with a mixing tube 302. The liquid flow regulating assembly 301 may input a liquid to be mixed, which may include a first liquid and a second liquid, to the mixing tube 302. The liquid flow rate adjusting component 301 may be used to adjust the output flow rate of the first liquid, and may further adjust the output ratio of the first liquid to the second liquid, so as to input the first liquid and the second liquid with different ratios into the mixing tube 302 for mixing.

The liquid flow regulation assembly 301 may include a base 310 and a liquid distribution wheel 320. Optionally, the liquid flow regulation assembly 301 may further comprise a transmission 330. Optionally, the liquid flow regulation assembly 301 may include an upper cap 340 and a lower cap 350. The upper cover 340 may cover a side surface of the base 310. The lower cover 350 may cover the other side of the base 310 opposite to the other side. The upper cover 340 and the lower cover 350 may serve to protect the dispensing wheel 320 and the transmission mechanism 330.

As shown in fig. 7, the base 310 may be provided with a receiving chamber 311 for receiving the first liquid and a first output port 313 communicating with the receiving chamber 311.

Specifically, the first output port 313 is for outputting the first liquid within the accommodating chamber 311. The first water pump 210 may be communicated to the accommodating chamber 311 to be able to inject the first liquid into the accommodating chamber 311. Alternatively, the base 310 may be provided with a first input port 312, where the first input port 312 is connected to the accommodating cavity 311, and is used for inputting the first liquid into the accommodating cavity 311 through the first input port 312. Specifically, the first water pump 210 may be communicated to the first input port 312 through a corresponding pipe. Optionally, the accommodating cavity 311 and the first output port 313 are formed on a side surface of the base 310. The first input port 312 is also disposed on a side of the base 310. The upper cover 340 covers at least the accommodating chamber 311 to protect the liquid separating wheel 320 accommodated in the accommodating chamber 311.

The liquid separating wheel 320 is rotatably accommodated in the accommodating cavity 311 and is used for dividing the first liquid in the accommodating cavity 311 into at least two sub-liquids. And, the liquid separating wheel 320 outputs at least two sub-liquids to the outside of the accommodating chamber 311 through the first output port 313 in portions, respectively, by rotation.

Optionally, the outer circumference of the liquid separating wheel 320 is provided with a plurality of liquid separating gear teeth 321 which are distributed along the axial direction at intervals, and tooth grooves 322 are formed between adjacent liquid separating gear teeth 321. Each spline 322 may be configured to receive a portion of the sub-liquid, such that the first liquid may be divided into a plurality of portions of the sub-liquid. The liquid separation wheel 320 may sequentially deliver each sub-liquid to the first outlet 313 by rotation. The distance between the tip of the liquid dividing gear tooth 321 and the inner wall of the accommodating chamber 311 may be 0.03 to 1.5mm, alternatively 0.05 to 1.3mm, alternatively 0.08 to 1.2mm, alternatively 0.1 to 1mm, alternatively 0.2 to 0.8mm, alternatively 0.3mm, 0.5mm or 0.6mm. By configuring the distance between the tooth tips of the liquid dividing gear teeth 321 and the inner wall of the accommodating cavity 311 to be 0.05-1.5mm, the width of the gap between the liquid dividing gear teeth 321 and the inner wall of the accommodating cavity 311 can be located at a reasonable position, the flow of sub-liquid between the tooth grooves 322 is reduced, and each part of sub-liquid in the tooth grooves 322 is more uniform.

The transmission mechanism 330 is disposed on the base 310 and is in transmission connection with the liquid separation wheel 320. The transmission mechanism 330 can be used to generate corresponding motion, such as rotation, to drive the liquid separation wheel 320 to rotate. The liquid separating wheel 320 is configured to output at least two portions of the sub-liquid to the outside of the accommodating cavity 311 through the first output port 313 by portions by rotation. For example, each time the liquid separating wheel 320 rotates by a predetermined angle, a portion of the sub-liquid is output to the outside of the accommodating chamber 311.

The first liquid is divided by the liquid dividing wheel 320, and the liquid dividing wheel 320 forces the sub-liquid to flow by rotation. When the sub-liquid flows to the first output port 313, the sub-liquid flows out of the accommodating chamber 311 through the first output port 313 due to a pressure difference. The liquid separation wheel 320 can sequentially output multiple parts of sub-liquid out of the accommodating cavity 311 through the first output port 313 in the rotation process, can divide the first liquid in the accommodating cavity 311 into multiple parts, and output each part of sub-liquid out of the accommodating cavity 311, so that the single output flow of the first liquid can be effectively reduced, the sub-liquid can be smoothly output by utilizing the hydraulic pressure brought by the rotation of the liquid separation wheel 320, and the reflux of the sub-liquid can be reduced. By utilizing the liquid separation function and rotation of the liquid separation wheel 320, the control of small flow can be realized, and the first liquid can be finely divided by adjusting the indexing relation of the liquid separation wheel 320, so that the flow of each sub liquid of single output of the first liquid can be effectively adjusted.

The transmission mechanism 330 can generate intermittent motion, and can drive the liquid separation wheel 320 to intermittently rotate during the motion. The liquid separating wheel 320 is used for outputting at least two parts of sub-liquid to the outside of the accommodating cavity 311 through the first output port 313 in parts by intermittent rotation. That is, under the driving of the transmission mechanism 330, the liquid separation wheel 320 can intermittently rotate, and each rotation can drive one portion of the sub-liquid to be output to the outside of the accommodating cavity 311 through the first output port 313, so that at least two portions of the sub-liquid can be output to the outside of the accommodating cavity 311 through the first output port 313. Alternatively, intermittent rotation of the tap wheel 320 may cause one of the gullets 322 to be rotated to be disposed opposite the first output port 313, thereby enabling sub-liquid of that gullet 322 to be output through the first output port 313.

The intermittent motion generated by the transmission mechanism 330 is utilized to drive the liquid separation wheel 320 to intermittently rotate, the liquid separation wheel 320 and the transmission mechanism 330 can form a set of indexing mechanism, the first liquid in the accommodating cavity 311 can be divided into a plurality of parts, each part of liquid can be orderly and clearly output to the outside of the accommodating cavity 311 by utilizing the intermittent motion, and then the single output flow of the first liquid can be effectively reduced, the mutual interference between each part of liquid can be reduced, and further the output flow of each part of liquid can be better controlled. In addition, the flow rate of each sub-liquid of the single output of the first liquid can be effectively adjusted by adjusting the transmission mechanism 330 and the liquid separation wheel 320, so that the control of smaller flow rate can be realized. In addition, the flow control is realized by utilizing the transmission coordination between the transmission mechanism 330 and the liquid separation wheel 320, and the structure is stable, safe and reliable.

The transmission mechanism 330 may be one of a geneva mechanism, a ratchet mechanism, an incomplete gear mechanism, a cam unidirectional intermittent motion mechanism, and an escapement mechanism. The mechanism can generate intermittent motion through movement, and the intermittent motion is utilized to drive the liquid separation wheel 320 to rotate.

As shown in fig. 7, taking the driving mechanism 330 as a sheave mechanism as an example, the driving mechanism 330 may include a dial 331 and a sheave 332. The dial 331 and the sheave 332 are rotatably provided to the base 310, respectively. Alternatively, the dial 331 and the sheave 332 are rotatably provided on the other side surface of the base 310 facing away from the accommodating chamber 311, respectively. Optionally, a mounting groove 317 is formed on the other side of the base 310 facing away from the accommodating cavity 311, a sheave 332 and a dial 331 are rotatably accommodated in the mounting groove 317, and a first transmission member 335 penetrates the base 310 to connect the sheave 332 and the liquid separating wheel 320. The lower cover 350 may cover the other side of the base 310 facing away from the accommodating cavity 311, so as to cover the mounting groove 317, thereby protecting the transmission mechanism 330, etc.

Specifically, as shown in fig. 7 and 8, the dial 331 may be provided with a dial pin 333. The toggle pin 333 may be provided at an edge of the dial 331. The dial 331 may drive the dial pin 333 to rotate in the circumferential direction during the circumferential rotation. The periphery of the sheave 332 is provided with at least two radial slots 334 spaced apart. That is, the direction of extension of the radial slots 334 is consistent or substantially consistent with the radial direction of the sheaves 332. The poking pin 333 is movably embedded in the radial groove 334. In the circumferential rotation process of the dial 331, the dial pin 333 drives the sheave 332 to rotate in a radial groove 334, the sheave 332 stops rotating after rotating by a certain amplitude, and the dial pin 333 drives the sheave 332 to rotate after continuously rotating along with the dial 331 and entering into the adjacent other radial groove 334, so that the sheave 332 can realize intermittent rotation. In summary, the dial 331 may intermittently rotate the sheave 332 via the dial pin 333. The grooved wheel 332 is in transmission connection with the liquid separating wheel 320, so that the liquid separating wheel 320 can be driven to intermittently rotate.

Through setting up geneva mechanism as drive mechanism 330, because geneva 332 has obvious graduation relation, can have good correspondence between the tooth's socket 322 of radial groove 334 and minute liquid wheel 320, be convenient for carry out the structure and match the design, can conveniently realize setting up radial groove 334 and tooth's socket 322 quantity according to actual flow demand, and then be convenient for the flow control to first liquid, geneva mechanism stable in structure moreover, the transmission is connected between geneva 332 and minute liquid wheel 320, can export stable intermittent type nature rotation to minute liquid wheel 320, and then realize the purpose that reduces first liquid output flow effectively.

Alternatively, sheave 332 and distribution wheel 320 are drivingly connected by a first drive 335. The first transmission member 335 penetrates through two opposite sides of the base 310, and is further fixedly connected to the sheave 332 and the liquid separation wheel 320 located on two opposite sides of the base 310. Specifically, the first transmission member 335 may be provided in a shaft shape, that is, the first transmission member 335 is a transmission shaft. The sheave 332 and the liquid separation wheel 320 are coaxially and fixedly connected to the first transmission member 335 so that the two can rotate synchronously. Thus, once the sheave 332 rotates, the distributor 320 rotates once.

Alternatively, the number of radial slots 334 may be the same as the number of tooth slots 322 of the tap wheel 320, and the positions of the radial slots 334 and the tooth slots 322 may be in one-to-one correspondence. In this way, the first liquid in the accommodating cavity 314 can be effectively divided by the corresponding relationship between the number and the position of the two, and each sub-liquid is sequentially output through the first output port 313 by intermittent rotation. The tooth grooves 322 can be uniformly formed in the periphery of the liquid separation wheel 320, so that the first solution in the accommodating cavity 311 can be uniformly divided, and the supply of small flow or ultra-small flow can be conveniently realized.

For example, the number of tooth slots 322 of the tap wheel 320 is 20, and the number of radial slots 334 is also 20. The pulling pin 333 is from entering one radial slot 334 to exiting the radial slot 334, and drives the sheave 332 to rotate once, so that the pulling pin 333 exits one radial slot 334 before entering the adjacent other radial slot 334, and the sheave 332 is suspended. Once the sheave 332 rotates, the liquid separation wheel 320 rotates once, and the tooth slot 322 changes position once. The present embodiment can select the tap wheel 320 and the sheave 332 of the corresponding tooth slot 322 according to the actually required output flow.

In one exemplary scenario, the first water pump 210 may operate intermittently in coordination with the operation of the tapping wheel 320 and the transmission 330 capable of producing intermittent motion. For example, when the first water pump 210 works, the first liquid fills the accommodating cavity 311 through the first input port 312, the first liquid in the accommodating cavity 311 is divided into multiple parts through the liquid separating wheel 320 and the transmission mechanism 330, and each part is sequentially conveyed out of the accommodating cavity 311 through the first output port 313 until the first liquid in the accommodating cavity 311 is completely conveyed out of the accommodating cavity 311, and then the first water pump 210 is started to work again to fill the accommodating cavity 311 with the first liquid, so that a circulation mode of 'emptying-filling-emptying' can be formed, each part of sub-liquid can be further conveniently output through the liquid separating wheel 320 in a small flow mode, and the problems of overlarge hydraulic pressure of the accommodating cavity 311 caused by a pump body, output faults and the like are reduced.

In this embodiment, the driving dial 331 may be driven to rotate in various manners, for example, the driving dial 331 may be driven to rotate manually, the driving dial 331 may be driven to rotate by the motor 203, or the driving dial may be driven by other manners. One of them is exemplified below.

As shown in fig. 7 and 9, the base 310 may be provided with a receiving cavity 314, and a second input port 315 and a second output port 316 communicating with the receiving cavity 314. The accommodating chamber 314 and the accommodating chamber 311 are arranged at intervals. The liquid flow regulation assembly 301 may include a drive wheel 360. The driving wheel 360 is rotatably accommodated in the accommodating cavity 314. The driving wheel 360 is arranged to be rotatable under the pushing of the second liquid via the second inlet 315, the receiving chamber 314 and the second outlet 316. The driving wheel 360 is in transmission connection with the transmission mechanism 330 for driving the transmission mechanism 330 to move.

The receiving cavity 311 and the receiving cavity 314 may be disposed at a side of the base 310 at intervals. The driving wheel 360 is rotatably accommodated in the accommodating cavity 314. The second water pump 220 may be connected to the second inlet 315 via a corresponding line and may be capable of pumping a second liquid into the receiving cavity 314 via the second inlet 315. The second liquid enters the accommodating cavity 314 through the second input port 315, and can generate thrust to the driving wheel 360 to push the driving wheel 360 to rotate. After the drive wheel 360 rotates, the second fluid flows therewith and then out of the second outlet 316. The drive wheel 360 can move the transmission 330. For example, the transmission 330 may generate intermittent motion in motion that can cause intermittent rotation of the dispensing wheel 320. Of course, the drive wheel 360 may be driven by other means, such as by a motor.

By driving the driving wheel 360 to rotate by pushing the second liquid input accommodating cavity 311, the transmission mechanism 330 is driven to move, so that no new power source is required to be additionally introduced, no additional noise source is required to be introduced, not only can energy be effectively saved, but also noise can be effectively reduced.

Optionally, the second input port 315 communicates with the accommodating cavity 314 along a tangential direction of the accommodating cavity 314, so as to be capable of inputting the second liquid along the tangential direction of the accommodating cavity 314 through an inner wall of the accommodating cavity 314, thereby pushing the driving gear teeth 362. Further, the second liquid can be continuously input into the accommodating cavity 314 through the second input port 315 by the first water pump 210, so that the driving wheel 360 can be continuously rotated, and the driving mechanism 330 can be driven to continuously move. For example, the transmission 330 may stably generate intermittent motion by continuous motion.

Through setting up second input port 315 along holding chamber 314 tangential direction intercommunication holding chamber 314 for second liquid can be along holding chamber 314 tangential direction through holding chamber 314's inner wall input holding chamber 314, like this second liquid can preferentially strike the outer end that drive teeth 362 kept away from circular base member 361, make the thrust that drive teeth 362 received the biggest, further improve power conversion efficiency, can promote drive teeth 362 rotation more effectively, and then make drive wheel 360 can realize stable rotation.

Specifically, as shown in fig. 7, a driving wheel 360 is drivingly connected to the dial 331. For example, the drive wheel 360 is drivingly connected to the dial 331 via a second drive member 336. The second transmission member 336 penetrates through two opposite sides of the base 310, and is further fixedly connected to the driving plate 331 and the driving wheel 360 located on two opposite sides of the base 310. Specifically, the second transmission member 336 may be disposed in a shaft shape, that is, the second transmission member 336 is also a transmission shaft. The dial 331 and the driving wheel 360 are coaxially and fixedly connected to the second transmission member 336 so that they can rotate synchronously. In this way, the driving wheel 360 synchronously drives the driving plate 331 to rotate in the rotating process, and the driving plate 331 drives the sheave 332 to intermittently rotate through the driving pin 333, so as to drive the liquid distributing wheel 320 to intermittently rotate.

Alternatively, as shown in fig. 10, the driving wheel 360 may include a circular base 361 and driving gear teeth 362 spaced apart from an edge of the circular base 361, and the driving gear teeth 362 may extend outwardly from the circular base 361 in a direction of flow of the second liquid around the circular base 361 to deviate from a radial direction of the circular base 361, for example, from a radial direction of the circular base 361 passing a root of the driving gear teeth 362, so that the second liquid can push the driving gear teeth 362 to rotate the driving wheel 360.

The extension direction of the driving cog 362 is offset by a corresponding angle θ, e.g., 5-10 °, 3-30 °, 8-15 °, etc., with respect to the radial direction across its root. The direction of deflection is in the direction of the flow of the second liquid around the circular base 361, e.g., the second liquid flows around the circular base 361 in a counterclockwise direction, and the direction of extension of the driving gear teeth 362 deviates from the corresponding radial direction in a counterclockwise direction. The number of the driving gear teeth 362 may be plural, and the specific number may be designed according to practical situations, which is not limited herein.

Through setting up the extending direction of gear and deviating corresponding radial in the flow direction of second liquid for the second liquid is penetrated into and is produced the thrust to driving teeth of a cogwheel 362 effectively after receiving chamber 314, and then promotes driving teeth of a cogwheel 362 rotation smoothly, improves the validity that the second liquid promoted driving teeth of a cogwheel 362, improves power conversion efficiency.

The mixing device 300 may also enable mixing of the first liquid and the second liquid. The above and references to the first liquid being output at a small flow rate and the second liquid being output at a relatively large flow rate. In this way, the first liquid may be mixed in a smaller proportion with a larger proportion of the second liquid. For example, the first liquid is a cleaning agent and the second liquid is clear water, although the first and second liquids may be other liquids.

As shown in fig. 7, the mixing tube 302 is disposed on the base 310 and is capable of communicating with the first outlet 313 and the second outlet 316 to receive the first liquid and the second liquid. The mixing tube 302 may be used to mix the first liquid output through the first output port 313 and the second liquid output through the second output port 316. Specifically, the base 310 may be provided with a placement groove 318 and a liquid outlet 319, and the liquid outlet 319, the first output port 313, and the second output port 316 are communicated with the placement groove 318. The mixing tube 302 may be disposed in the placement tank 318 and may be in communication with the first output port 313, the second output port 316, and the liquid discharge port 319, the liquid discharge port 319 being configured to discharge the liquid mixed by the mixing tube 302.

For the contents of the mixing tube 302 of this embodiment, reference may be made to the description of embodiments of the mixing tube 302 of the present application described below.

As shown in fig. 11, the mixing tube 302 may be provided with a mixing channel 371. The mixing channel 371 may communicate with the first output port 313 and the second output port 316 for receiving the first liquid and the second liquid. The first liquid and the second liquid are inputted into the mixing channel 371 as liquids to be mixed. Optionally, the mixing tube 302 may also be provided with an inlet 372 and an outlet 373. The mixing channel 371 may be in communication between the inlet 372 and outlet 373 chambers. The liquid inlet chamber 372 is used for communicating the first output port 313 and the second output port 316. The liquid outlet chamber 373 is used for communicating the liquid outlet 319.

Alternatively, the mixing tube 302 may be provided with a liquid inlet 3701 and a liquid outlet 3702. The number of liquid inlets 3701 may be plural for receiving liquid to be mixed and inputting the liquid to be mixed into the mixing channel 371. For example, the number of liquid inlets 3701 may be 2 for receiving the first liquid and the second liquid, respectively. The number of the liquid outlets 3702 may be one or more, and the liquid outlets may be used to output the liquid mixed by the mixing channel 371. The liquid inlet 3701 and the liquid outlet 3702 communicate with both ends of the mixing channel 371, respectively, i.e., the mixing channel 371 may communicate between the liquid inlet 3701 and the liquid outlet 3702. Of course, the liquid inlet 3701 and the liquid outlet 3702 may be located at the same end of the mixing tube 302, or may be located at two ends of the mixing tube 302. Fig. 11 shows a case where the liquid inlet 3701 and the liquid outlet 3702 are located at both ends of the mixing tube 302, respectively, and the mixing channel 371 is opened between both ends of the mixing tube 302. Specifically, the liquid inlet 3701 communicates with the liquid inlet 372, and the liquid outlet 3702 communicates with the liquid outlet 373.

As shown in fig. 12, the liquid inlet chamber 372 may be provided in a triangular shape, and the mixing channel 371 communicates with the liquid inlet chamber 372 at a corner of the liquid inlet chamber 372. The liquid outlet chamber 373 is arranged in a triangle, and the mixing channel 371 is communicated with the liquid outlet chamber 373 at one corner of the liquid outlet chamber 373. Through setting up the feed liquor chamber 372 in great space and play liquid chamber 373, can store more liquid after waiting to mix and mixing, and then make mixing channel 371 can smoothly mix, the feed liquor chamber 372 in great space can make first liquid and second liquid get preliminary mixing after getting into feed liquor chamber 372 in addition to can together input and carry out further mixing in mixing channel 371.

The mixing channel 371 of the present embodiment may be provided so as to enhance the mutual collision of the liquids to be mixed therein to achieve the mixing and homogenizing effect.

In order to enable the mixing channel 371 to strengthen the collision between the liquids to be mixed, the present embodiment shows one of exemplary structures of the mixing channel 371 as follows:

as shown in fig. 12, the mixing channel 371 may include a main channel 374 and at least one bypass channel 375, both ends of each bypass channel 375 communicating with the main channel 374, respectively.

That is, at least one bypass channel 375 is provided on the extension path of the main channel 374, and an inlet and an outlet of the bypass channel 375 communicate with the main channel 374, respectively. The liquid to be mixed enters the main channel 374, part of the liquid can enter the bypass channel 375 in the flowing process, the liquid in the main channel 374 can become a 'main stream', the liquid in the bypass channel 375 can become a 'sub-stream', and as both ends of the bypass channel 375 are communicated with the main channel 374, the main stream and the sub-stream are branched and converged, so that the collision of the liquid is enhanced. The collision of liquid can strengthen the mutual fusion of first liquid and second liquid, and then reaches the purpose of mixing, so can realize passive static mixing, can need not initiative stirring, convenient and fast, and the mixing effect is showing.

Alternatively, the number of bypass channels 375 may be 1-15, alternatively 3-10, alternatively 5-8, alternatively 7, 9. The main channel 374 may be alternatively provided with side channels 375 at both sides thereof, so that a better mixing effect may be achieved.

In order to further enhance the mixing effect of the liquids to be mixed, the mixing channel 371 may be arranged so as to enable a vortex or vortex-like effect of the liquids to be mixed therein. Specifically, a diverter 376 is defined between the main passage 374 and each of the bypass passages 375. The diverter 376 may be configured such that the flow of the liquid to be mixed from the diverter 376 through the bypass channel 375 and the main channel 374, respectively, may create a boundary layer effect. The shunt portions 376 are, for example, island-like structures.

The boundary layer effect is generally referred to as: at high reynolds numbers the velocity of the viscous fluid flowing around the two dimensions of the airfoil increases sharply from a zero value on the wall surface to a value of the same order as the incoming flow velocity in the very narrow boundary layer, so that the velocity gradient in the direction normal to the wall surface is large, and even if the dynamic viscosity coefficient of the fluid is small, the viscous force can still reach a large value, so that the viscous force and the inertial force in the boundary layer are of the same order. Due to the large velocity gradient there is considerable swirl strength in the fluid and hence swirling flow within the boundary layer. When the swirling flow in the boundary layer is separated from the wall surface, a wake area with a more obvious speed gradient is formed behind the object, and due to the influence of viscosity, swirling vortex in the wake gradually diffuses, and the kinetic energy of the vortex gradually becomes heat energy to dissipate.

In short, due to the boundary layer effect, after the liquid separated along the surface of the diversion portion 376 through the bypass channel 375 enters the main channel 374, strong vortex opposite flow occurs to the liquid in the main channel 374, which is just where the liquid collides and mixes with each other. Since the diffusion phenomenon caused by the eddy current hedging can occur in a small space, the space occupied by the mixing channel 371 can be greatly reduced, and the mixing effect can be well improved.

In order to further strengthen the mutual collision and opposite impact of the liquid, the main channel 374 may be provided in a zigzag shape, and the liquid in the main channel 374 may further collide due to the existence of the bending part during the flowing process, so as to further improve the mixing effect.

Specifically, as shown in fig. 12, the main channel 374 may be provided in a zigzag shape, for example, including a plurality of sub-channels 3741 provided in a straight line. The multiple sub-channels 3741 are sequentially communicated, and adjacent sub-channels 3741 are connected in a zigzag manner, so that the main channel 374 can be in a zigzag shape. Alternatively, the number of sub-channels 3741 may be 2-20, 5-15, 6-10, 7-9, or 8. Of course, the main passage 374 may be linearly disposed. The zigzag connection between the adjacent sub-channels 3741 means that the extending directions of the adjacent sub-channels 3741 form an included angle, and the included angle can be set according to actual requirements.

Alternatively, each adjacent two of the sub-passages 3741 communicate with one of the bypass passages 375 in common, and an upstream sub-passage 3741 of each adjacent two of the sub-passages 3741 communicates with an inlet of the corresponding bypass passage 375 in the liquid flow direction of the main passage 374, wherein the downstream sub-passage 3741 communicates with an outlet of the corresponding bypass passage 375.

In other words, one bypass channel 375 may bridge two adjacent sub-channels 3741. In the direction of liquid flow of the main passage 374, each adjacent two sub-passages 3741 are located one upstream and the other downstream. Wherein the upstream sub-channel 3741 communicates with the inlet of the corresponding bypass channel 375 and wherein the downstream sub-channel 3741 communicates with the outlet of the corresponding bypass channel 375. The liquid to be mixed diverges in the upstream sub-passage 3741, partially enters the side passage 375, and partially flows into the downstream sub-passage 3741. The liquid from the bypass channel 375 flows further into the downstream sub-channel 3741 where it mixes with the liquid in the downstream sub-channel 3741. On the basis of the zigzag connection of the adjacent sub-channels 3741, the bypass channel 375 is communicated with the adjacent sub-channels 3741 in a bridging manner, so that a more complex passage structure can be formed, the collision and opposite impact of liquid in the flowing process can be further enhanced, and the mixing effect is further improved.

Further, since two adjacent sub-channels 3741 are zigzag-connected, the two sub-channels 3741 arranged in a straight line are connected to have a reflex angle and a bad angle. Corresponding bypass channels 375 may be provided at the reflex angle of each adjacent two sub-channels 3741.

As shown in fig. 13, the bypass channel 375 may be provided in an arc shape. For example, the bypass channel may include an inlet segment 3751 disposed in a straight line, an outlet segment 3752 disposed in a straight line, and an arcuate segment 3753. The arcuate segment 3753 communicates between the inlet and outlet segments 3751, 3752, and in this embodiment, a straight arrangement may mean a substantially straight arrangement, allowing for some error as long as the error does not affect the flow and mixing of the liquids.

The inlet section 3751 and the upstream sub-passage 3741 therein are in linear communication. Specifically, the inlet section 3751 is directly connected to the end of the upstream sub-passage 3741 therein, so that the liquid of the upstream sub-passage 3741 can be smoothly branched into the bypass passage 375 through the branching portion 376 to be able to better generate the boundary layer effect.

The outlet section 3752 communicates with the middle of the sub-passage 3741 downstream therein. That is, the liquid flowing out through the outlet section 3752 merges into the sub-passage 3741 at the middle of the sub-passage 3741 located downstream therein. Here, the middle portion is distinguished from the end portions, and is located between both ends and can be regarded as the middle portion, and is not limited to the most intermediate position.

Optionally, the component of the liquid flow direction of the outlet section 3752 in the direction of extension of the sub-channel 3741 downstream therein is zero, i.e. the liquid flow direction of the outlet section 3752 is perpendicular or substantially perpendicular to the direction of extension of the sub-channel 3741, such that part of the liquid passing through the outlet section 3752 collides with the liquid in the sub-channel 3741 in the direction of vertical convergence, thereby maximizing the effect of the mixing of the two by the opposite collision. While a portion of the liquid flowing along the surface of the diverter 376, which otherwise flows through the outlet segment 3752, due to the boundary layer effect, is able to collide against the liquid of the sub-channel 3741, creating a swirling effect. In this way, all the liquid flowing out through the outlet section 3752 can generate a strong collision opposite impact effect with the liquid in the sub-channel 3741, and the mixing effect is improved.

Alternatively, the component of the liquid flow direction of the outlet section 3752 in the direction of extension of the subchannel 3741 located downstream therein is opposite to the liquid flow direction of the subchannel 3741 located downstream therein. That is, the liquid flow direction of the outlet section 3752 merges with the liquid flow of the corresponding sub-passage 3741 in a diagonal manner. The component of the liquid flow direction of the outlet section 3752 in the direction of extension of the respective sub-channel 3741 may be a horizontal component. The liquid flow direction of the outlet section 3752 then also has a vertical component perpendicular to the horizontal component. The horizontal component is opposite to the liquid flow direction of the corresponding sub-channel 3741. By providing the outlet section 3752 with a component of the liquid flow direction in the direction of extension of the downstream sub-channel 3741 therein that is opposite to the liquid flow direction of the downstream sub-channel 3741 therein, the collision and opposite of the liquid flowing out of the outlet section 3752 and the liquid of the corresponding sub-channel 3741 can be made more direct, the force is greater, the swirling effect can be further improved, and the first liquid and the second liquid can be mixed more uniformly.

Optionally, the size of the outlet of the bypass channel 375 is greater than the size of the inlet of the bypass channel 375. This arrangement allows the liquid in the bypass channel 375 to impinge on the liquid in the impingement sub-channel 3741 in a wider range of ways, thereby enhancing the mixing effect.

Optionally, the size of the outlet section 3752 increases gradually in the direction of the liquid flow of the outlet section 3752. This arrangement provides a large liquid converging region of the outlet section 3752 and the sub-passage 3741, which facilitates the formation of a vortex at the outlet location of the outlet section 3752, where the liquid of the bypass passage 375 and the liquid of the sub-passage 3741 can be thoroughly mixed. The dimensions of the outlet and inlet of the bypass channel 375, the dimensions of the outlet section 3752, may here be cross-sectional areas, for example, meaning cross-sectional areas in a plane perpendicular to the flow direction of the liquid to be mixed as cross-section.

In summary, by arranging the liquid separating wheel 320 and the transmission mechanism 330, the liquid is separated into multiple parts by the liquid separating wheel 320, and the transmission mechanism 330 is utilized to drive the liquid separating wheel 320 to move, for example, intermittently move, so that each part of liquid is sequentially output, the liquid can be sequentially output after being separated into multiple parts, the output flow of the liquid is reduced, and the control of the flow is realized.

In the mixing pipe 302, by providing the mixing channel 371 including the main channel 374 and at least one bypass channel 375, both ends of each channel are respectively communicated with the main channel 374, so that the main flow and the sub-flow can be enhanced by the bifurcation-confluence manner, thereby enhancing the effect of mixing.

The foregoing description is only illustrative of the present application and is not intended to limit the scope of the application, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present application.
