When the partition plate 522 is in the shape of a concave plate in the middle, it can guide the airflow after the first stage of filtration upwards to reduce the operating noise of the gas-liquid separator; Guiding the airflow after the first level of filtration can not only buffer the flow rate of the airflow to the second filter cavity 532, but also help dirt such as dust and small liquid droplets to fall downward.

As an embodiment of the present application, the filter element 52 also includes a first ring body 521 that can be supported and connected to the inner cylinder 512, and the first ring body 521 is arranged at one end of the cylindrical filter element 525 to enhance the overall integrity of the filter element 52. strength.

As an embodiment of the present application, in order to prevent the airflow from entering the inner cylinder 512 too quickly and affecting the separation rate, the inner cylinder 512 is limited to be provided with an inverted cone cylinder 513; the through hole 5130 is provided on the inverted cone cylinder 513, and the filter element 52 It is arranged in the inner cylinder 512 and is arranged on the upper part of the inverted cone cylinder 513 .

Referring to Fig. 2 and Fig. 3, as an embodiment of the present application, in order to prevent the airflow from entering the through hole 5130 too quickly, the lower part of the inner tube 512 has a skirt 5121 extending along its circumference; preferably, the skirt 5121 is in the vertical direction The inverted cone 513 is at least partially covered. Wherein, the above-mentioned skirt can be completely closed along the circumferential direction, or discontinuous (composed of multiple small skirts at intervals), all of which can hinder the flow of dirt to the inverted cone 513 .

Furthermore, the longitudinal section of the lower end portion 5122 of the skirt is set in a pointed shape; based on this structure, after the water vapor attached to the outer wall of the inner cylinder 512 condenses into water droplets, it is more conducive to dripping from the lower end portion 5122 of the skirt instead of Facilitates sliding to the inside of the skirt.

In a specific application scenario, the filter element 52 may rotate relative to the cyclone cone 51 along its circumference. To solve this problem, referring to Fig. 4 and Fig. 5, the inner cylinder 512 or the inverted cone cylinder 513 is limited to be provided with a number of limiting grooves 5131 , the second ring body 524 is provided with a limiting block 5241 that can be mated and plugged into the limiting slot 5131 .

Based on this, dirt such as dust and small liquid droplets flowing down from the inner cylinder 512 and the cylindrical filter element 525 can pass through the gap 5244 and the gap 5132 and flow out from the through hole 5130 .

Referring to Fig. 2, Fig. 3 and Fig. 12, in order to be able to support the dust and gas separator 5, as an embodiment of the present application, the lower part of the cyclone cone 51 is fixed with a pillar 514.

Specifically, the pillar 514 can be fixed to the outer cylinder 511, the inner cylinder 512, the skirt 5121 or the inverted cone 513 through connecting ribs (not shown in the figure), and the space between adjacent connecting ribs can be regarded as a through hole 5130; further Ground, the notch 5132 corresponds to the position of the connecting rib (that is, one end of the connecting rib is connected to the position of the notch); in this way, the dirt flowing out from the notch 5132 can directly adhere to the connecting rib, and follow the length direction of the connecting rib Downward flow, so that the airflow entering the through hole 5130 affects the downward movement of the dirt as little as possible,

Referring to Figures 10-14, the present invention also provides a gas-liquid separator, including a dust cylinder 101 and the dust-gas separator 5 in any of the above-mentioned embodiments; the dust-gas separator 5 is arranged in the dust cylinder 101, and both Together, they form a dust bin assembly.

As an embodiment of the present application, the dust-gas passage 510 is spirally arranged downwards, so that when the fluid is exported from the dust-gas passage 510, it can move downward along the trend, and can be thrown out to the outer periphery according to the centrifugal force, thereby colliding with the dust. On the inner wall of the cylinder 101; the kinetic energy of the dust and small liquid droplets is reduced after impact, thus falling downward.

In one embodiment, the gas-liquid separator further includes a shell 1 configured with an air inlet channel 41 and an air outlet channel 43, and a first cavity in fluid communication with the air inlet channel 41 is formed inside it; and a transfer channel 42, for achieving fluid communication between the first cavity and the dust box assembly;

Wherein, the dust cylinder assembly is arranged in the first cavity, which is in fluid communication with the air outlet channel 43; at least a part of the fluid entering the first cavity through the air inlet channel 41 bypasses the dust cylinder assembly, Enter the transit passage 42.

The above-mentioned fluid in the present application can be clean airflow, also can be the airflow that entrains dirt; at least one of water, egg liquid, etc.).

It can be understood that the second cavity 1010 (that is, the inner space of the dust tube 101 ) which is not directly communicated with the first cavity is configured in the dust cylinder assembly; when the fluid flows in the first cavity, part or all of the fluid After bypassing the outer peripheral surface of the dust cylinder assembly, it flows to the transfer channel 42 .

Specifically, the above-mentioned outer peripheral surface includes at least a part of the outer peripheral surface that goes clockwise or a part of the outer peripheral surface that goes counterclockwise.

Based on the above settings, the walking path of the fluid in the first cavity is lengthened, that is, the fluid trajectory from the outlet end of the air inlet channel to the inlet end 421 of the transfer channel is increased; in this way, the dirt trapped in the airflow can also be more fully The ground collides with other obstructive components such as the inner wall of the housing and the outer wall of the dust cylinder assembly to dissipate the kinetic energy, thereby falling and storing at the bottom of the first cavity.

It is worth noting that referring to FIG. 14 , the fluid directly enters the dust gas passage 510 through the outlet end 422 of the transfer passage; . The second cavity 1010 can store the dust, small liquid droplets, etc. that are guided out of the dust gas channel 510 and collide with the inner wall of the dust cylinder 101 and fall; then, the airflow separated from the dust and small liquid droplets flows through the inner cylinder 512 to the outlet. Wind channel 43 .

As an embodiment of the present application, the dust cylinder assembly and the inlet port 421 of the transfer channel are basically arranged along the width direction of the gas-liquid separator; it can be understood that the dust cylinder assembly is arranged in the first cavity, along the width of the gas-liquid separator Direction, the inlet end 421 of the transfer passage is arranged on one side or the other side of the dust cylinder assembly. The outlet end of the air inlet channel is configured not toward the inlet port 421 of the transfer channel; it can be understood that the airflow derived from the outlet end of the air inlet channel has an export direction (the initial flow direction when the airflow is exported), and the airflow introduced through the inlet end of the transfer channel It has an introduction direction (the direction when the airflow enters the inlet end of the transfer channel), and the space formed by the outlet end of the air inlet channel along the outlet direction does not intersect the space formed by the inlet end of the transfer channel along the introduction direction. In this way, the fluid can flow to the inlet end 421 of the transfer channel without too fast, thereby reducing the probability that the dirt is directly sucked into the inlet end of the transfer channel.

Referring to Figures 11-13, in the preferred embodiment, the outlet end of the air inlet channel is basically away from the inlet end of the transfer channel; the left and right directions are defined as the width direction of the gas-liquid separator, and the dust cylinder assembly is basically arranged on the left side of the inlet end 421 of the transfer channel side, and the outlet end of the air inlet channel is located at the front side or the rear side of the dust cylinder assembly and is basically set towards the left side. Based on the above structure, the traveling path of the fluid includes as many parts as possible bypassing the dust cylinder assembly, thereby improving the separation rate of the gas-liquid separator.

Further, the entrance end 421 of the transfer channel may be arranged substantially downward in the vertical direction, or may be arranged substantially toward the right.

As a preference of this embodiment, all the fluid entering the first cavity bypasses one side of the outer peripheral surface of the dust cylinder assembly away from the inlet end 421 of the transfer passage, so that the travel path of all the fluid is lengthened, and the dirt The quality of the collision drop effect is better.

In one embodiment, the casing 1 includes a lower casing 11 and an upper casing 12, and the upper casing 12 can be opened relative to the lower casing 11, so as to facilitate the disposal of the dirt stored in the first chamber. Wherein, a quick-release component is arranged between the lower shell 11 and the upper shell 12, so that the user can quickly open/close the upper shell 12; specifically, the above-mentioned quick-release component can choose a locking structure well-known to those of ordinary skill in the art, One of the buckle structure, the magnetic attraction structure, etc. can also be selected for combination, and can also be used in combination with a pivot structure, which is not further limited in this application.

Referring to FIG. 13 , as a preferred embodiment, the quick release assembly of the present application includes a buckle structure 132 and a pivot structure 131 .

As an embodiment of the present application, the transfer channel 42 and the air outlet channel 43 are arranged on the upper shell 12, and the air inlet channel 41, the first cavity and the second cavity are arranged on the lower shell 11; in order to facilitate the cleaning of the dust and gas separator 5 , which is detachably inserted on the upper shell 12 .

When the dust and gas separator 5 is inserted into the upper case 12, it is easy to sink. In order to solve this problem, the present application supports the pillar 514 from the lower part.

Further, a supporting post 1011 may be provided in the dust cylinder 101 to support the supporting post 514 . Wherein, the abutment post 1011 and the support post 514 can both be set in a solid shape to directly abut against each other; or at least one of them can be set in a sleeve shape to be plugged in to abut against each other.

When closing the upper case 12, in order to enable the post 1011 to limit the position of the post 514 in the horizontal direction, in this embodiment, the post 1011 is preferably set in a sleeve shape, and the post 514 can be inserted therein; in order to make the post 514 in the upper case 12 can be conveniently inserted into the abutting post 1011 in the flipped closed state, and the lower end of the defined post 514 is provided with chamfered or rounded corners. Furthermore, when the dirt flowing out from the notch 5132 flows down along the length direction of the connecting rib, it can flow into the second cavity 1010 along the pillar 514 and the resisting pillar 1011 successively.

When the gas-liquid separator is used to clean the dirt, the dirt falling in the first cavity will inevitably shake. In order to prevent the dirt after shaking from being directly sucked away by the inlet end 421 of the transfer channel, the first cavity is defined A baffle 111 is arranged in the middle, and the baffle 111 is arranged at the lower part of the inlet end 421 of the transfer channel.

Referring to Fig. 12, by setting the above-mentioned baffle plate 111, the first cavity can be understood as being decomposed into a first sub-cavity 1021, a second sub-cavity 1022 and a third sub-cavity 1023; wherein, the first sub-cavity 1021 is located on the baffle plate On the left side of 111 , the dust cylinder assembly is arranged in the first sub-chamber 1021 , and the second sub-chamber 1022 and the third sub-chamber 1023 are respectively located on the upper side and the lower side of the baffle plate 111 .

Under the action of suction, the fluid enters the first sub-chamber 1021 from the air inlet channel 41 and moves along the airflow direction; cavity 1021, the second sub-cavity 1022, and the third sub-cavity 1023; however, obviously, the dirt in the third sub-cavity 1023 is relatively less. Due to the setting of the baffle 111, the suction force at the position of the inlet end 421 of the transfer channel has a smaller force on the dirt in the first sub-chamber 1021 and the second sub-chamber 1022, thereby improving the separation of airflow, solid and liquid Rate.

In one embodiment, the baffle 111 has a first end close to the dust cylinder assembly and a second end away from the dust cylinder assembly, the second end is configured to be higher than the first end, that is, the baffle 111 is inclined downward toward the dust cylinder assembly In this way, when the dirt is in the third sub-cavity 1023, it may be introduced into the first sub-cavity 1021 or the second sub-cavity 1022 under the action of gravity, which not only facilitates the centralized storage of the dirt, but also prevents the third sub-cavity from Garbage is stored in the cavity, which will have a bad impact on the gas path.

In a specific application scenario, the cross section of the tuyere at the inlet end 421 of the transfer passage can be a regular shape such as a circle, an ellipse, a rectangle, or an irregular shape; The cross-section of the tuyere at the inlet end 421 of the transfer channel is set in a slit shape. Specifically, the ratio of the maximum length to the maximum width of the tuyere section is not greater than 5; wherein, the directions of the maximum length and maximum width are perpendicular. For example, when the section of the tuyere is rectangular, define the length of the long side as the maximum length and the length of the short side as the maximum width; when the section of the tuyere is irregular, define the length of the longest section of the tuyere as the maximum length, and then compare Find the maximum width in the direction perpendicular to the direction.

In one embodiment, the gas-liquid separator provides suction through a motor, and the above-mentioned motor has a motor air inlet; the cross-sectional area of the air outlet at the inlet end 421 of the transfer channel is 1.5-2 times the area of the air inlet of the motor; this can limit and relieve the inlet port of the transfer channel The suction at the 421 position is conducive to the separation of water and air.

In a specific application scenario, when the distance between the baffle plate 111 and the inlet end 421 of the transfer channel is relatively close, it is easy to form a pumping effect, making it easier for the dirt to be sucked from the inlet end 421 of the transfer channel; When the distance is long, the third sub-chamber 1023 is too large, and the dirt is easy to move into this space, thereby increasing the risk of the dirt flowing out from the inlet end 421 of the transfer channel.

In the present application, there is a first distance d between the inlet end 421 of the transfer channel and the baffle plate 111, and the first distance is the minimum distance between the inlet end 421 of the transfer channel and the baffle plate 111; the first distance d is 12-20 mm, preferably the first distance d A distance d is 15mm.
