An embodiment of the present invention provides a filter 20 (see fig. 1) applied to a cleaning device 200 (see fig. 2), wherein the cleaning device 200 includes a sewage tank 300, and the filter 20 is disposed in a tank 10 of the sewage tank 300. Specifically, the cleaning device 200 is a scrubber. It should be understood that in other embodiments, the type of the cleaning device 200 is not limited.

The cleaning device 200 includes a body 100 and a wastewater tank 300, and the wastewater tank 300 is provided in the body 100. When the cleaning device 200 is operated, the sewage formed after the washing is sucked into the sewage tank 300 to be collected, thereby cleaning the floor.

The sewage tank 300 includes a tank body 10 (see fig. 3) and a filter member 20 (see fig. 1), the tank body 10 having a sewage collecting space 11 therein, the filter member 20 being detachably provided in the sewage collecting space 11. The filter member 20 includes a filter body 21, and the filter body 21 divides the soil collecting space 11 into a dry garbage space 111 and a wet garbage space 112. The solid waste is stored in the dry waste space 111 by the filter member 20 and the sewage flows to the wet waste space 112, thereby achieving separation of the solid waste and the sewage. When the garbage is dumped, the filtering piece 20 is taken out of the box body 10, the solid garbage can be independently poured into the garbage basket, and the sewage in the box body 10 is poured into a discharge device such as a closestool or a water tank, so that the blockage of the discharge device such as the closestool or the water tank is effectively prevented.

As discussed in the background of the invention, conventional filter elements 20 are prone to clogging, and when filter element 20 becomes clogged, its filtering effect will fail. At this time, the sewage hardly or not flows into the wet garbage space 112, the mixture of the solid garbage and the sewage is tumbled in the dry garbage space 111, and the sewage is easily sucked into the motor directly to cause the damage of the motor.

In order to solve the above problem, referring to fig. 4 and 5, the filter body 21 includes a first filter portion 211 and a second filter portion 212, and the first filter portion 211 and the second filter portion 212 are sequentially arranged in a flow direction of the fluid. Thus, when the sewage passes through the filter member 20, both the first filter portion 211 and the second filter portion 212 can perform a filtering function, and the filter member 20 is not easily clogged. Meanwhile, since the first filter portion 211 and the second filter portion 212 can perform a filtering function, the filtering effect of the filter member 20 is improved to a certain extent.

Specifically, solid media in the fluid can be trapped in the first filter portion 211 or the second filter portion 212. Finally, the solid garbage is retained in the first filtering part 211 or the second filtering part 212, and the first filtering part 211 or the second filtering part 212 blocks the solid garbage from flowing from the dry garbage space 111 to the wet garbage space 112.

In one embodiment, the filter body 21 includes a first main body 213, the second filter portion 212 is formed on the first main body 213, and the first filter portion 211 is protruded on the first main body 213. In the flow direction of the fluid, the solid medium in the fluid is retained in the first filter portion 211.

It should be noted that, when the filtering member 20 filters, the solid waste in the sewage first contacts with the upper surface 214 of the first filtering portion 211 away from the first main body 213, and after the solid waste is gathered on the upper surface 214 of the first filtering portion 211 for a certain time, the solid waste increases and slides down to the root of the first filtering portion 211 connected with the first main body 213 to gather along with the impact of the sewage. Thus, the first filtering part 211 blocks the solid garbage from flowing from the dry garbage space 111 to the wet garbage space 112.

In one embodiment, with reference to fig. 4 and 5, the first filter portion 211 includes a plurality of first ribs 215, and the first filter portion 211 has a fence-like structure formed by the first ribs 215 in a criss-cross manner. When the filtering member 20 is used for filtering, solid waste in the sewage first contacts with the upper surface 214 of the first filtering portion 211 far away from the first main body 213, even if the solid waste blocks the upper surface 214 of the first filtering portion 211, the sewage can flow to the second filtering portion 212 from the side surface 216 of the first filtering portion 211, and when the solid waste slides to the root of the first filtering portion 211 connected with the first main body 213 and is gathered, the sewage can flow to the second filtering portion 212 from the upper surface 214 of the first filtering portion 211, so that the blocking of the filtering member 20 is not easily caused.

The first rib 215 has a U-shape, both ends of the U-shape of each first rib 215 are connected to the first body 213, and a first opening of the U-shape faces the second filter part 212. It should be understood that in other embodiments, the shape of the first webs 215 is not limited.

Further, the first body 213 is a flat plate structure, the second filter part 212 is a through hole formed on the first body 213, and the first rib 215 of the first filter part 211 is protruded from the first body 213 to a height of 10 mm. That is, the filter member 20 provided in the present embodiment is formed by moving up the filter structure by 10mm, compared to the filter member 20 in which the filter structure is directly formed on the plate-shaped first body 213 in the related art. It is contemplated that, in other embodiments, the specific structure of the second filter portion 212, the formation manner of the first filter portion 211, and the height of the first body 213 are not limited.

In another embodiment, referring to fig. 6-8, the first filter portion 211 includes at least two second rib plates 217 having a plate shape, and all of the second rib plates 217 are spaced in a first direction intersecting the flow direction. Thus, when the filtering member 20 performs filtering, solid waste in the sewage first contacts the upper surface 214 of the first filtering portion 211, which is far from the first main body 213, and even if the solid waste blocks the upper surface 214 of the first filtering portion 211, the sewage can flow from the side surface 216 of the first filtering portion 211 to the second filtering portion 212, and when the solid waste slides to the root portion where the first filtering portion 211 is connected to the first main body 213 and is collected, the sewage can flow from the upper surface 214 of the first filtering portion 211 to the second filtering portion 212, so that the blocking of the filtering member 20 is not easily caused.

Further, the first main body 213 is a flat plate structure, the second filter part 212 is a grid-shaped structure formed on the first main body 213, the second filter part 212 includes at least two third rib plates 218 in a plate shape, one second rib plate 217 is convexly arranged on one first rib plate 215, and the first main body 213 and the first filter part 211 are integrally formed. Thus, the mold structure can be simplified compared to the above-described manner in which the first filter part 211 is provided in the fence-like structure in which the first rib plates 215 are arranged in a criss-cross manner.

Furthermore, a part of the second rib plates 217 protrudes out of the first main body 213 by a first height, the remaining part of the second rib plates 217 protrudes out of the first main body 213 by a second height, and the second rib plates 217 protruding out of the first main body 213 by the first height and the second rib plates 217 protruding out of the first main body 213 by the second height are sequentially arranged at intervals in the first direction. That is, the height of the second rib 217 protruding from the first body 213 is different, so that the arrangement can prevent the solid garbage strips (such as noodles) from closing all the grills, and if the solid garbage strips exist on the second rib 217 with a higher height, the second rib 217 with a lower height can still allow the liquid to flow through.

It should be understood that in other embodiments, all of the second rib plates 217 may be arranged at the same height, and are not limited herein.

In one embodiment, the filter body 21 has two first filter parts 211 and two second filter parts 212, and each first filter part 211 is disposed corresponding to each second filter part 212. The two first filter parts 211 are spaced apart from each other, and the two second filter parts 212 are spaced apart from each other. With this arrangement, the number of filter portions is large, and the filtering effect of the filter member 20 can be improved.

Specifically, the two first filter portions 211 are opposed in the radial direction of the filter body 21, and the two second filter portions 212 are opposed in the radial direction of the filter body 21. Thus, the sewage is filtered by one of the first and second filtering parts 211 and 212, and the air in the wet garbage space 112 is discharged from the other of the first and second filtering parts 211 and 212, so that the air pressure in the sewage collecting space 11 is kept balanced, and the sewage can flow from the dry garbage space 111 to the wet garbage space 112 without interruption. It should be noted that, while one of the first filter portion 211 and the second filter portion 212 performs the primary filtering function, a part of the sewage can flow from the other one of the first filter portion 211 and the second filter portion 212 to the wet garbage space 112, that is, the other one of the first filter portion 211 and the second filter portion 212 can perform the secondary filtering function.

Further, the waste water tank 300 further includes a backflow preventing structure 30 (see fig. 1), the backflow preventing structure 30 is connected to the first main body 213 and is communicated with one of the second filtering portions 212, the waste water in the dry waste space 111 can enter the wet waste space 112 through at least the backflow preventing structure 30 for storage, and the backflow preventing structure 30 can prevent the waste water in the wet waste space 112 from flowing therethrough and entering the dry waste space 111.

In the cleaning apparatus 200 with the soil bin 300, when the body 100 is erected (for example, when the angle with respect to the horizontal plane is 60 to 110 degrees, hereinafter, simply referred to as "erected"), the soil enters the wet garbage space 112 from the dry garbage space 111 through the backflow preventing structure 30 and is stored in the wet garbage space 112. When the body 100 is largely inclined (for example, the angle with respect to the horizontal plane is less than or equal to 30 degrees, or even about 2 degrees, hereinafter referred to as "flat"), the backflow prevention structure 30 prevents the sewage in the wet garbage space 112 from flowing backward through the backflow prevention structure 30 into the dry garbage space 111, so that the sewage does not flow to the motor, the motor does not stop, and the cleaning apparatus 200 can still work normally. Thus, the cleaning apparatus 200 with the sump 300 can be used not only when the main body 100 is erected, but also when the main body 100 is largely inclined, even laid flat, greatly facilitating the user.

Further, the foul water tank 300 further includes a first sealing member 40, and the first sealing member 40 is disposed between the first body 213 and the tank 10 to prevent foul water in the wet garbage space 112 from flowing back into the dry garbage space 111 from between the first body 213 and the tank 10 when the cleaning device 200 is in normal use. The sump 300 further includes a second sealing member 50, and the second sealing member 50 is disposed between the backflow preventing structure 30 and the first body 213 to prevent the sewage in the wet garbage space 112 from flowing back into the dry garbage space 111 from between the backflow preventing structure 30 and the first body 213 when the cleaning device 200 is in normal use. Specifically, the first seal 40 and the second seal 50 are both ring-shaped structures.

The box body 10 is further provided with a sewage channel 14, and the sewage channel 14 is communicated between the outside and the sewage collecting space 11. The sewage formed after the washing flows from the sewage passage 14 to the sewage collecting space 11 to be collected.

Referring to fig. 1, the box body 10 includes a box body 12 and a cover 13, the sewage channel 14 is disposed on the box body 12, and the cover 13 is detachably disposed at an opening of the box body 12 and defines a sewage collecting space 11 with the box body 12. Thus, the convenient filter element 20 is taken out from the opening of the box body 12, and the sewage collected in the box body 10 can be poured conveniently.

Referring to fig. 9, the tank body 12 includes a bottom wall 121, a side wall 122, and a sewage pipe 123, and the sewage pipe 123 is connected to an inner surface of the bottom wall 121 and disposed at an angle to the bottom wall 121. The side wall 122 is connected to the outer side of the bottom wall 121 and extends toward the same direction as the extension direction of the sewage pipe 123, the side wall 122 is disposed around the sewage pipe 123, and the cover 13, the bottom wall 121, the side wall 122, and the sewage pipe 123 define and form the sewage collecting space 11. The sewage channel 14 is formed in the sewage pipe 123, the sewage collecting space 11 is communicated with the sewage outlet of the sewage channel 14, and the opening of the whole box body 10 is formed at one end of the sewage collecting space 11 communicated with the sewage outlet, so that the cover of the cover body 13 is convenient to cover.

The filter element 20 further comprises a socket 22 (see fig. 4 and 6), the socket 22 being connected to the first body 213 and extending into the dry waste space 111. The sleeve pipe 22 is sleeved outside the sewage pipe 123 to facilitate the assembly of the filter member 20. The waste tank 300 further includes a third sealing member provided between the socket pipe 22 and the waste pipe 123 to prevent the waste water in the wet waste space 112 from flowing back into the dry waste space 111 from between the socket pipe 22 and the waste pipe 123 when the cleaning apparatus 200 is in normal use.

The filter 20 further includes a blocking wall 23 (see fig. 4 and 6) connected to the first main body 213, the blocking wall 23 is connected to the periphery of the first main body 213 and extends in the same direction as the sleeve 22, and the blocking wall 23 and the first main body 213 form a containing space for containing the solid waste. In this way, the blocking wall 23 can block the solid waste from falling into the housing 10 during the removal of the filter member 20 from the dirt collecting space 11. Specifically, the blocking wall 23 is provided with draining holes, so that the solid waste can be prevented from falling off, the sewage can be discharged into the box body 10 as much as possible, and the separation effect of the solid waste and the sewage is improved.

An air flow channel 131 (see fig. 1) is provided on the cover 13, an inlet of the air flow channel 131 is communicated with the sewage collecting space 11, and the recovery system is communicated with an outlet of the air flow channel 131 to draw air from the tank 10, thereby sucking the sewage into the tank 10. In one embodiment, the waste water tank 300 further includes a filter screen 60, and the filter screen 60 is disposed at an outlet of the air flow path 131 to filter fine solid waste contained in the air to prevent the solid waste from clogging the motor of the recycling system. Specifically, the filter screen 60 includes a nylon filter screen 61 and a filter sponge 62, the nylon filter screen 61 performs a first-stage filtering effect of the gas, and the filter sponge 62 performs a second-stage filtering effect of the gas.

In another embodiment, referring to fig. 10 to 12, the center of the filter body 21 is recessed with respect to the edge thereof to form a receiving chamber 219 having a second opening 2191, and the receiving chamber 219 has an inner diameter gradually decreasing from one end having the second opening 2191 to the other end. The receiving chamber 219 has a first chamber wall 2192 and a second chamber wall 2193, the second chamber wall 2193 is disposed between the first chamber wall 2192 and the edge of the filter body 21, the first filter part 211 is formed on the second chamber wall 2193, and the second filter part 212 is formed on the first chamber wall 2192. The fluid can be swirled to the second filter portion 212 through the first filter portion 211, and the solid media in the fluid can be retained in the second filter portion 212. Thus, when the sewage passes through the filtering member 20, both the first filtering portion 211 and the second filtering portion 212 can perform filtering function, and finally the solid garbage is retained in the second filtering portion 212, and the second filtering portion 212 blocks the solid garbage from flowing from the dry garbage space 111 to the wet garbage space 112, so that the blockage of the filtering member 20 is not easily caused. In particular, the filter member 20 of the present embodiment is generally applied to a place where the sewage tank 300 is stably placed, such as a large floor washing machine, or a sewage tank beam 300 of a charging base station.

It should be noted that, in this embodiment, the sewage pipe 123 may be omitted from the tank body 12, and the sewage flows directly from the sewage inlet on the side wall of the sewage collecting space 11 to be collected, and the socket pipe 22 may also be omitted from the filter member 20.

It should be noted that the inner diameter of the accommodating chamber 219 gradually decreases from one end having the second opening 2191 to the other end means that: the inner diameter of the accommodation chamber 219 from the end having the second opening 2191 to the other end is not absolutely continuously reduced, allowing for a portion having an equal inner diameter. In one embodiment, the first chamber wall 2192 is recessed in a bulbous shape facing away from the second opening 2191 to facilitate the accumulation of solid waste in the second filter portion 212. It should be understood that in other embodiments, the first cavity wall 2192 may be disposed in other ways, and is not specifically limited herein.

The second cavity wall 2193 is obliquely disposed between the first cavity wall 2192 and the edge of the filter body 21. Because the first filter portion 211 is formed on the second chamber wall 2193, when the second chamber wall 2193 is obliquely arranged at the edge of the first chamber wall 2192 and the filter body 21, the fluid can be conveniently swirled to the second filter portion 212 through the first filter portion 211.

Further, the second chamber wall 2193 includes a first sub-wall 2194 and a second sub-wall 2195 (see fig. 11) which are connected to each other and disposed obliquely, the first sub-wall 2194 is disposed between the first chamber wall 2192 and the second sub-wall 2195, and the second sub-wall 2195 is connected to an edge of the filter body 21. The first filter unit 211 is provided on the first sub-wall 2194 and/or the second sub-wall 2195.

In one embodiment, the first filter portion 211 is disposed on the first sub-wall 2194 and the second sub-wall 2195 to improve the filtering effect of the first filter portion 211. In another embodiment, the first filter portion 211 may be only disposed on the first sub-wall 2194. In another embodiment, the first filter portion 211 may be disposed only on the second sub-wall 2195.

Referring to fig. 12, when the first filter part 211 is disposed on the first sub-wall 2194 and the second sub-wall 2195, the second sub-wall 2195 and the first sub-wall 2194 are gradually inclined toward the first chamber wall 2192, so that the sewage can be gradually accelerated to improve the filtering effect. Filter element 20 further includes a flow guiding rib 24 (see fig. 10 and 13), and flow guiding rib 24 is disposed in accommodating cavity 219, and the solid medium in the fluid flows to second filter portion 212 through flow guiding rib 24. The drainage ribs 24 can extend the path of the solid medium flowing to the second filter part 212, thereby facilitating the filtration of the sewage. Meanwhile, the drainage ribs 24 can smooth out solid waste such as hair and the like so as to reduce the blockage of the solid waste to the filter element 20.

In another embodiment, the flow guiding rib 24 is arc-shaped (see fig. 13), and the flow guiding rib 24 is annularly arranged outside the first filtering portion 211. Specifically, the filter member 20 includes two flow guiding ribs 24, and the two flow guiding ribs 24 are arranged at intervals in the surrounding direction around the first filter portion 211. Thus, when the filter member 20 filters, the solid waste can only surround the flow guiding ribs 24 and flow to the second filter portion 212 through the gap between the two flow guiding ribs 24, thereby improving the filtering effect.

In yet another embodiment, the filter element 20 includes a plurality of flow-guiding ribs 24, and all of the flow-guiding ribs 24 are connected and arranged between the first filter portion 211 and the second filter portion 212 in a windmill shape (see fig. 10). The solid flows to the second filter part 212 through the gap between the two drainage ribs 24 under the guiding action of the drainage ribs 24, so that the filtering effect is improved.

It should be understood that in other embodiments, the drainage ribs 24 may take other shapes, and are not limited herein.

Another embodiment of the present invention also provides a sewage tank 300 including the filter member 20. The present invention further provides a cleaning device 200 including the above-mentioned sewage tank 300 according to still another embodiment. The advantageous effects of the filter member 20 have been described above, and the sump 300 and the cleaning device 200 have corresponding advantageous effects, which will not be described in detail herein.
