In the description of the present application, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

In this application, unless expressly stated or limited otherwise, the first feature "on" or "under" the second feature may comprise direct contact of the first and second features, or may comprise contact of the first and second features not directly but through another feature in between. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

The present application provides a treatment agent delivery device, as shown in fig. 1 to 4, including: the device comprises a first chamber 1A, a rotating mechanism 2 and a throwing mechanism, wherein the first chamber 1A is provided with a first water inlet 1011 and a second water inlet 1012; the rotating mechanism 2 is disposed in the first chamber 1A, and the rotating mechanism 2 includes: a rotor 21, and a first blade group and a second blade group which are arranged on the rotor 21 at intervals; the throwing mechanism is connected with the rotating body 21 and is used for throwing the treating agent under the driving of the rotating body 21; the water flow entering from the first water inlet 1011 is matched with the first blade group and is suitable for pushing the rotating body 21 to rotate along the first direction so as to control the throwing mechanism to throw in the first treating agent; the water entering from the second water inlet 1012 cooperates with the second blade set and is adapted to push the rotor 21 to rotate in the second direction to control the dispensing mechanism to dispense the second treatment agent.

It can be understood that the water flow entering from the first water inlet 1011 cooperates with the first blade group to drive the rotating body 21 to rotate clockwise, and the water flow entering from the second water inlet 1012 cooperates with the second blade group to drive the rotating body 21 to rotate counterclockwise; or, the water flow entering from the first water inlet 1011 cooperates with the first blade group to drive the rotating body 21 to rotate counterclockwise, and the water flow entering from the second water inlet 1012 cooperates with the second blade group to drive the rotating body 21 to rotate clockwise. Therefore, the rotating mechanism 2 can drive the feeding mechanism to feed different treating agents under the action of water flow, the structure is simplified, the arrangement space is saved, an electric driving device can be omitted, and cost is saved.

In some embodiments, the first chamber 1A further comprises a water outlet 1013, the first water inlet 1011 and the second water inlet 1012 are located on a first side of the first chamber 1A, and the water outlet 1013 is located on a second side of the first chamber 1A, the second side being opposite to the first side or being perpendicular to each other. If the water flow flows in from the first water inlet 1011 and flows out from the water outlet 1013, the rotating body 21 is driven to rotate along the first direction; if water flows in from the second water inlet 1012 and flows out from the water outlet 1013, the rotating body 21 is driven to rotate in the second direction.

Exemplarily, the first water inlet 1011 and the second water inlet 1012 are located at a first side of the housing 1, and the water outlet 1013 is located at a second side of the housing 1 opposite to the first side; if the water flows in from the first water inlet 1011 and flows out from the water outlet 1013, the rotating body 21 is driven to rotate in a first direction (counterclockwise direction in fig. 3); if water flows in from the second water inlet 1012 and flows out from the water outlet 1013, the rotating body 21 is driven to rotate in the second direction (clockwise direction as shown in fig. 4). It will be appreciated that if water flows into the first water inlet 1011 and the second water inlet 1012 at the same time at similar flow rates, the power of the rotating body 21 is offset, and the stationary state can be maintained, but the water flow can be normally discharged from the water outlet 1013. In this manner, by controlling the water supply states of the first water inlet 1011 and the second water inlet 1012, the switching of the clockwise rotation, the counterclockwise rotation, and the stationary state of the rotating body 21 can be realized under the condition that the first chamber 1A normally supplies water. In practical application, the first water inlet 1011 and the second water inlet 1012 can be communicated with a water supply waterway through electromagnetic valves, and the rotation state of the rotating body 21 can be effectively controlled by controlling the water supply states of the first water inlet 1011 and the second water inlet 1012 through the electromagnetic valves.

It is understood that the number of the water outlets 1013 may be plural, and those skilled in the art can reasonably set the number according to the requirement, and the number is not limited herein.

It is understood that the position of the water outlet 1013 can be appropriately set by one skilled in the art according to the requirement, and is not limited herein. Such as: the plane of the water outlet 1013 may be perpendicular to or opposite to the plane of the first water inlet 1011 and the second water inlet 1012.

In some embodiments, as shown in fig. 1, 3 and 4, the first chamber 1A is substantially formed as a cylindrical chamber, a first side of the first chamber 1A extends outward to form a first water inlet pipe 1020 and a second water inlet pipe 1021, the first water inlet pipe 1020 and the second water inlet pipe 1021 are arranged in parallel and are respectively located at upper and lower ends of the first chamber 1A, a second side of the first chamber 1A extends outward to form a water outlet pipe 1022, and the water outlet pipe 1022 is located in the middle of the first chamber 1A.

Illustratively, a first water inlet 1011 is formed at an inlet of the first water inlet pipe 1020, a second water inlet 1012 is formed at an inlet of the second water inlet pipe 1021, and a water outlet 1013 is formed at an outlet of the water outlet pipe 1022; when water flows in from the first water inlet 1011, the rotating mechanism 2 is driven to rotate along the first direction; the water flow is introduced from the second water inlet 1012, and the rotating mechanism 2 is driven to rotate in the second direction.

In some embodiments, as shown in fig. 2, the rotating mechanism 2 further includes a baffle 24, and the baffle 24 is located between the first blade group and the second blade group for separating the first blade group from the second blade group. As shown in fig. 2, the first blade group includes a plurality of first blades 22, the plurality of first blades 22 are located on an upper side of the shroud 24, and the plurality of first blades 22 are arranged in a circumferential direction of the rotor 21. The second vane group includes a plurality of second vanes 23 located at a lower side of the baffle 24, and the plurality of second vanes 22 are arranged along a circumferential direction of the rotating body 21. Here, the first blade 22 and/or the second blade 23 may be a curved blade or a straight blade, where the straight blade means that the surface of the blade is planar and rotates under the driving of the water flow; the curved surface blade means that the surface of blade is the curved surface form to make the blade have the radian of setting for, do benefit to and form rotatory vortex, thereby improve rotation efficiency.

In some embodiments, the first blade 22 and the second blade 23 are both curved blades, and the curved direction of the first blade is opposite to the curved direction of the second blade. As shown in fig. 3 and 4, the first blade 22 is bent clockwise, so that the water entering from the first water inlet 1011 exerts a counterclockwise pressure on the first blade 22, thereby driving the rotating body 21 to rotate counterclockwise. The second vane 23 is curved in a counterclockwise direction to apply a clockwise pressure to the second vane 23 by the water flow introduced from the second water inlet 1012, thereby driving the rotating body 21 to rotate in a clockwise direction. Thus, the double-sided blades of one impeller (namely the rotating mechanism 2) can be utilized to efficiently rotate forwards or backwards under the action of water flow, and different treatment agents are respectively put in the impeller through the driving of the rotating body 21 and the putting mechanism.

It will be appreciated that the baffle 24 is located between the first blade set and the second blade set for separating the first blade 22 from the second blade 23, reducing the possibility of the water entering the first water inlet 1011 acting on the second blade set and reducing the possibility of the water entering the second water inlet 1012 acting on the first blade set, thereby improving the hydrodynamic conversion efficiency.

In some embodiments, the center of the rotating body 21 is provided with a rotating shaft connection hole structure 211, and the input shaft of the releasing mechanism can be matched with the rotating shaft connection hole structure 211 on the rotating body 21, so as to transmit the power of the rotating body 211 to the releasing mechanism.

In some embodiments, the rotator 21 is provided with a plurality of through holes 212, and the through holes 212 can reduce the weight of the rotator 21, thereby facilitating the rotator 21 to rotate under the driving of water flow. In addition, the through holes 212 can prevent the water staying in the rotating body 21 from interfering with the rotation of the rotating body 21, thereby further improving the rotation efficiency of the rotating body 21.

In some embodiments, the first blade set, the second blade set, the rotator 21 and the baffle 24 are integrally formed, so that the rotating mechanism 2 has an integral structure, and the assembly process is simplified. In other embodiments, the rotating mechanism 2 may be assembled by a separate structure.

In some embodiments, as shown in fig. 1, the delivery mechanism comprises: a second chamber 1C, a speed reduction mechanism 3, a power distribution mechanism 4, and a distribution mechanism. Wherein the second chamber 1C has a first loading port 1016 and a second loading port 1018. The speed reducing mechanism 3 is connected with the rotating mechanism 2 and is used for reducing the speed and increasing the torque of the power output by the rotating mechanism 2 and then outputting the power. The power split device 4 is connected to the output end of the reduction mechanism 3, and the power split device 4 has a first output end and a second output end for transmitting the power output from the reduction mechanism 3. The distribution mechanism is arranged in the second chamber 1C and comprises a first distribution mechanism 5 and a second distribution mechanism 6, wherein the first distribution mechanism 5 is connected with the first output end and is used for controlling the throwing of the treating agent at the first liquid inlet 1016; the second dosing means 6 is connected to the second output for controlling the dosing of the treatment agent at the second inlet 1018.

Because the rotating mechanism 2 can be driven by the water flow flowing into the first chamber 1A through the first water inlet 1011 or the second water inlet 1012, the power output by the rotating mechanism 2 is output to the power distribution mechanism 4 after being decelerated and torque-increased by the deceleration mechanism 3, the power distribution mechanism 4 drives the first distribution mechanism 5 to control the feeding of the treating agent at the first liquid inlet 1016 or drives the second distribution mechanism 6 to control the feeding of the treating agent at the second liquid inlet 1018, so that the treating agent feeding device can utilize the water flow as a power source, the automatic feeding of the treating agent is realized, an electric driving device can be omitted, and the cost is saved. Here, the treating agent may be a liquid or powder detergent product required for washing, and those skilled in the art can make a reasonable choice according to the needs, which is not specifically limited in the present application.

In addition, it should be noted that, since the water pressure of the water flow fluctuates during the use, in the embodiment of the present application, the output power of the rotating mechanism 2 is transmitted to the power distribution mechanism 4 after being decelerated and torque-increased by the decelerating mechanism 3, can effectively widen the working range of water pressure of water flow, leads the water flow in a low water pressure state to drive the rotating mechanism 2 and then to be decelerated and torque-increased by the decelerating mechanism 3, thereby increasing the torque output from the power split mechanism 4, so that the first or

second dispensing mechanism

5, 6 can effectively control the dosing of the treating agent at the respective inlet, thereby realizing the automatic feeding of the treating agent, and because the first distribution mechanism 5 controls the feeding of the treating agent at the first liquid inlet 1016 and the second distribution mechanism 6 controls the feeding of the treating agent at the second liquid inlet, the classified automatic feeding of different types of treating agents can be realized, so that the control cost of the classified automatic feeding is further saved.

It is understood that the speed reducing mechanism 3 may include, but is not limited to: the gear reducer, the worm gear reducer or the planetary reducer is not particularly limited in this application as long as the power output by the water flow-driven rotating mechanism 2 can be converted into a larger output torque.

Exemplarily, as shown in fig. 1 and 5, the reduction mechanism 3 includes: a power shaft 301, a first reduction gear 302, a second reduction gear 303, and an output shaft 304. The first reduction gear 302 has a large end surface that meshes with the power shaft 301 and a small end surface that meshes with the second reduction gear 303. The power shaft 301 may extend into the first chamber 1A and be connected to the rotating mechanism 2, and be driven by the rotating mechanism 2. For example, the power shaft 301 is fixed in the rotating shaft connecting hole structure 211 of the rotating body 21 and is driven by the rotating body 21, and the power shaft 301 is matched with the large end face of the first reduction gear 302 to realize speed reduction; the small end face of the first reduction gear 302 is matched with the second reduction gear 303 again to realize speed reduction again; the second reduction gear 303 is connected to the output shaft 304 so that the power of the water flow can be transmitted to the power distribution mechanism 4 via the output shaft 304 after being reduced stepwise. It will be appreciated that the number of reduction gears provided between the power shaft 301 and the output shaft 304 may be set as required to meet the requirement of the reduction ratio.

In some embodiments, as shown in fig. 6 and 7, the speed reducing mechanism 3 includes: the power shaft 301, the planetary gear 305, the planet carrier 306 and the gear ring 307, wherein the power shaft 301 is connected with the rotating mechanism 2 and is driven by the rotating mechanism 2; the gear ring 307 is fixed to the housing 101, and it is understood that the gear ring 307 may be a separately provided ring member, and the inner wall of the ring member is provided with internal teeth, and the ring member is fixed in the third chamber 1B, or the gear ring 307 having an annular internal tooth surface is formed on the inner wall of the third chamber 1B; the planetary gear 305 is arranged between the power shaft 301 and the ring gear 307, and is in gear engagement with both the power shaft 301 and the ring gear 307; the carrier 306 is connected to the planetary gear 305, and outputs power to the power split mechanism 4 by being driven by the planetary gear 305. It will be appreciated that one end of the power shaft 301 may extend into the first chamber 1A and be fixedly connected to the turning mechanism 2, and the other end of the power shaft 301 is provided with external teeth meshing with the planetary gears 305, acting as a sun gear of the planetary reducer. The carrier 306 has an end portion for outputting power, which is connected to the input end of the power split mechanism 4.

In some embodiments, the reduction ratio of the reduction mechanism 3 is 30-150: 1. Therefore, the treating agent feeding device can normally work within the water pressure range of 0.03MPa to 1.0MPa, so that the treating agent feeding device has wide application prospect, for example, the treating agent feeding device can be applied to household appliances such as washing machines or dish washing machines.

It is understood that at least two of the aforementioned reduction mechanism 3, power split mechanism 4, and dispensing mechanism are located in the same chamber. In some embodiments, the power distribution mechanism 4 may be disposed in the third chamber 1B, i.e. the fourth chamber 1D is omitted, the third chamber 1B is located between the first chamber 1A and the second chamber 1C, so that the structure is compact, and the speed reduction mechanism 3 and the power distribution mechanism 4 are both located in the third chamber 1B, so that the treating agent delivering device has an attractive appearance. In some embodiments, the third chamber 1B and the fourth chamber 1D may be omitted, so that the speed reduction mechanism 3 and the power distribution mechanism 4 are both disposed in the second chamber 1C.

For example, the aforementioned speed reduction mechanism 3, power distribution mechanism 4 and distribution mechanism may be located in separate chambers. As shown in fig. 1, a third chamber 1B accommodating the reduction mechanism 3 and a fourth chamber 1D accommodating the power split mechanism 4 are formed in the casing 101, and the third chamber 1B and the fourth chamber 1D are located between the first chamber 1A and the second chamber 1C.

As shown in fig. 8, the power split mechanism 4 includes: a driving wheel 401, a first ratchet shaft 402, a driven wheel 403 and a second ratchet shaft 404; the driving wheel 401 is connected to an output end (such as the output shaft 304 shown in fig. 5 or the planet carrier 306 shown in fig. 6) of the speed reduction mechanism 3, and a first ratchet 4011 is arranged on an inner wall surface of the driving wheel 401; the first ratchet shaft 402 is sleeved in the driving wheel 401 and can rotate in a single direction in cooperation with the first ratchet 4011; the driven wheel 403 is meshed with the driving wheel 401, and the inner wall surface of the driven wheel 403 is provided with a second ratchet 4031; the second ratchet shaft 404 is sleeved in the driven wheel 403 and can rotate in one direction in cooperation with the second ratchet 4031. The first ratchet shaft 402 forms a first output terminal of the power distribution mechanism 4, and the second ratchet shaft 404 forms a second output terminal of the power distribution mechanism 4. It should be noted that the driving wheel 401 and the driven wheel 403 are engaged with each other by external teeth, the rotation directions of the driving wheel and the driven wheel are opposite, and the first ratchet shaft 402 and the second ratchet shaft 404 rotate in the same direction in one direction. For example, taking the first ratchet shaft 402 and the second ratchet shaft 404 both rotating clockwise in one direction as an example, when the driver 401 rotates clockwise, the first ratchet shaft 402 is driven by the first ratchet 4011 to rotate clockwise, the driven wheel 403 rotates counterclockwise, and the second ratchet shaft 404 is in slip fit with the second ratchet 4031; when the driver rotates counterclockwise, the first ratchet shaft 402 is engaged with the first ratchet 4011 in a slipping manner, the driven wheel 403 rotates clockwise, and the second ratchet shaft 404 rotates clockwise under the driving of the second ratchet 4031.

It is understood that the drive pulley 401 is connected to the output end of the reduction mechanism 3, i.e., to the output shaft 304 shown in fig. 5 or the end of the carrier 306 shown in fig. 6, to rotate under the power transmitted by the reduction mechanism 3. The driving wheel 401 and the first ratchet shaft 402 form a first ratchet assembly, and the driven wheel 403 and the second ratchet shaft 404 form a second ratchet assembly, specifically, an elastic pawl matched with the first ratchet 4011 is arranged on the outer wall surface of the first ratchet shaft 402, and the first ratchet shaft 402 can only rotate in one direction through the matching of the pawl and the first ratchet 4011; similarly, the outer wall surface of the second ratchet shaft 404 is provided with a pawl having elasticity and cooperating with the second ratchet 4031, so that the second ratchet shaft 404 can only rotate in one direction by the cooperation of the pawl and the second ratchet 4031. Since driving wheel 401 is in meshing engagement with driven wheel 403, for example, by teeth or pins, driving wheel 401 rotates in the opposite direction to driven wheel 403. As shown in fig. 8, in the case where the ratchet shaft and the ratchet teeth slip counterclockwise and rotate clockwise, for example, when the driver 401 rotates clockwise by the reduction mechanism 3, the driven wheel 403 rotates counterclockwise, and at this time, the first ratchet shaft 402 is pushed by the first ratchet teeth 4011 of the driver 401 and also rotates clockwise, but the second ratchet shaft 404 slips because the driven wheel 403 rotates counterclockwise, and no torque is transmitted. When the driver 401 is driven by the reduction mechanism 3 to rotate counterclockwise, the driven wheel 403 rotates clockwise, and the first ratchet shaft 402 slips and does not transmit torque, but the second ratchet shaft 404 rotates clockwise due to the driven wheel 403, and the second ratchet shaft 4042 rotates clockwise under the push of the second ratchet 4031 of the driven wheel 403, and outputs torque. In this manner, it is achieved that power is distributed to the first ratchet shaft 402 when the output shaft 304 rotates clockwise, and to the second ratchet shaft 404 when the output shaft 304 rotates counterclockwise.

It is understood that the second dispensing mechanism 6 may be a separate pump body or a pump body formed by cooperating with the inner wall surface of the second guide channel 1015.

Illustratively, as shown in fig. 1, the housing 1 further includes a second end cap 103, and the second end cap 103 cooperates with the casing 101 to form a second chamber 1C. The second chamber 1C has a first inlet 1016, a first outlet 10117, a second inlet 1018 and a second outlet 1019.
