[0018] The filter provided in this application can be used in various household appliances with cleaning systems, such as floor scrubbers and kitchen appliances. For example, it can be used in base stations of various cleaning systems or directly applied to cleaning systems. The following will introduce the use of the filter in the base station of the cleaning system as an example.

[0019] This application first proposes a filter, such as Figures 1 to 5 As shown, Figure 1 This is a schematic structural diagram of an embodiment of the filter of the present application; Figure 2 This is a schematic diagram of the exploded structure of an embodiment of the filter of the present application in the filtering state; Figure 3 This is a structural diagram of an embodiment of the filter element of the present application in a filtering state; Figure 4 This is a structural diagram of an embodiment of the filter of the present application in a non-filtering state;

[0020] Figure 5 Fig. 1 is a structural schematic diagram of an embodiment of a filter element in a non-filtering state. The filter comprises a filter element 10, a housing assembly 20, the filter element 10 is provided with a filtering cavity 103, a cavity wall of the filtering cavity 103 is provided with a first region 111, a second region 112 and a third region 113, the first region 111 is provided with a first inlet 101 in communication with the filtering cavity 103, and the second region 112 is provided with a plurality of filtering holes 102 in communication with the filtering cavity 103; the housing assembly 20 forms a containing cavity 203, a second inlet 201 and an outlet 202 in communication with the containing cavity 203; the filter element 10 is rotatably arranged in the containing cavity 203, and in the filtering state, fluid can flow into the first inlet 101 through the second inlet 201, enter the filtering cavity 103 from the first inlet 101, and flow out from the filtering holes 102 to the outlet 202.

[0021] The filter element 10 of the present application can be used to filter fluid, the fluid enters the filtering cavity 103 from the first inlet 101, and then flows to the filtering holes 102 to be filtered, the fluid is filtered at the filtering holes 102, the filtered residue is left in the filtering cavity 103, and the filtered fluid flows out of the filtering cavity 103; the filter element 10 is rotatably arranged relative to the housing assembly 20, so as to facilitate adjusting the relative position of the filter element 10 and the housing assembly 20 in different states (such as the filtering state and the non-filtering state), so that the filtering holes 102 and the outlet 202 can be selectively communicated, thereby improving the working state diversity of the filter, facilitating the user to switch the working state of the filter, and improving the operation convenience.

[0022] In some embodiments, when cleaning the filter element 10, the filter element 10 is rotated so that the third region 113 is located on the flow path of the fluid, thereby hindering the fluid from flowing out of the filtering cavity 103.

[0023] By rotating the filter element 10 so that the third region 113 prevents the fluid from flowing out of the filtering cavity 103, the hygiene of taking the filter element 10 when cleaning the filter element 10 can be improved, and the risk of fluid leakage when taking the filter element 10 can be reduced.

[0024] In some embodiments, in the filtering state, the filtering holes 102 are at least partially located at the bottom of the filter element 10, so that the fluid flows out of the filtering holes 102 under the action of gravity; when cleaning the filter element 10, the filter element 10 is rotated so that the third region 113 is located at the bottom of the filter element 10, and the first region 111 and the third region 113, and the second region 112 and the third region 113 are arranged along the vertical direction, so that the third region 113 is located on the flow path of the fluid, thereby hindering the fluid from flowing out of the filtering cavity 103.

[0025] Specifically, the third region 113 is not provided with the filter holes 102 or other through holes, and is a wall part of the cavity wall of the filter cavity 103; the filtering effect of the filter cavity 103 can be adjusted by adjusting the shape, size and number of the filter holes 102.

[0026] In the filtering state, the filter 10 can be used to filter fluid. The fluid enters the filter cavity 103 from the first inlet 101, and then flows to the filter holes 102 to be filtered. The fluid is filtered at the filter holes 102, and the filtered residue is left in the filter cavity 103. The fluid flows out of the filter cavity 103 through the outlet 202. The filter holes 102 are at least partially located at the bottom of the filter 10, which can use gravity to improve the filtering speed of the fluid flowing from the filter cavity 103 to the outside environment through the filter holes 102, thereby facilitating the improvement of the filtering efficiency. The use of gravity to discharge and filter the fluid can achieve energy saving. When the filter 10 needs to be cleaned, the filter 10 is rotated so that the third region 113 is located at the bottom of the filter 10. The third region 113 can receive the fluid in the filter cavity 103 that has not been filtered, which can reduce the risk of the fluid remaining in the filter cavity 103 flowing out of the filter cavity 103, especially when filtering is not needed. Rotating the filter 10 so that the third region 113 is located at the bottom of the filter 10 can reduce the risk of fluid dripping from the filter holes 102 of the filter 10 during the removal process when the filter 10 needs to be removed for cleaning, which can improve the hygiene of the cleaning operation of the filter 10. When the filter is applied to the base station of the cleaning system, the filter can be used to filter the fluid such as dirt flowing into the base station, which can reduce the risk of solid impurities in the sewage discharged from the base station causing the external system such as the external sewer to be blocked, thereby improving the user experience.

[0027] The fluid can be a solid-liquid mixed fluid, a solid mixed fluid (such as a mixed fluid of large particles and powdery solids), etc. The filter holes 102 play a role in filtering and separating the fluid. In some embodiments, the design of the filter holes 102 can be adjusted for different fluids.

[0028] In some embodiments, in the non-filtering state, the filter 10 can be rotated so that the third region 113 is located at the bottom of the filter 10. When the filter 10 is cleaned, the filter 10 can be first controlled to enter the non-filtering state.

[0029] In some embodiments, in the filtering state, the first region 111 and the second region 112 are arranged in the vertical direction, and the first region 111 is arranged above the second region 112. This arrangement facilitates the arrangement of the first inlet 101 above the plurality of filter holes 102, which facilitates the use of gravity to improve the speed of the fluid flowing from the first inlet 101 into the filter cavity 103 to the filter holes 102 in the filter cavity 103, thereby facilitating the improvement of the filtering efficiency.

[0030] In some embodiments, the filter of the present application can be used in a cleaning system, such as a floor sweeping machine system, a floor washing machine system, a sweeping and mopping integrated machine system, etc., for example, can be used in a base station of a cleaning system, for filtering fluids mixed with impurities, etc.; it should be noted that the fluid can flow into the filter under the action of gravity, or can flow into the filter by relying on negative pressure, or the combined action of gravity and negative pressure, without limitation.

[0031] In some embodiments, the filter 10 can also be connected to a driving assembly, which is in transmission connection with the cavity wall of the filter cavity 103, and the driving assembly can drive the cavity wall to change the position state, so as to realize the switching of the filtering state and the non-filtering state. This way is convenient for automatic switching and improves the user's convenience; of course, the filtering state and the non-filtering state can also be manually switched by artificial, for example, in other embodiments, the filter includes a main body part and a handle part connected and arranged, the main body part forms the filter cavity 103, and the filtering state and the non-filtering state can be switched by controlling the handle part, etc., which will not be described here.

[0032] In some embodiments, the filter 10 includes a cylindrical shell 11, which forms the filter cavity 103, the first inlet 101, and the plurality of filter holes 102, and the cylindrical shell 11 is provided with two end walls and a side wall, which is divided into a first region 111, a second region 112, and a third region 113.

[0033] The side wall of the cylindrical shell 11 is divided into the first region 111, the second region 112, and the third region 113, i.e., the filter holes 102 are arranged on the side wall of the cylindrical shell 11. In some embodiments, in the filtering state, the central axis of the filter hole 102 is arranged at an acute angle or parallel to the plumb line a of the cylindrical shell 11, for example, the axis b of the cylindrical shell 11 is parallel to the horizontal plane and the central axis of the filter hole 102 is arranged at an acute angle or parallel to the plumb line a of the cylindrical shell 11, or the axis b of the cylindrical shell 11 intersects the horizontal plane and the central axis of the filter hole 102 is arranged at an acute angle, wherein the central axis of the filter hole 102 is arranged at an acute angle or parallel to the plumb line a of the filter 10, which means that the filter hole 102 is directed obliquely downward or directly downward, so that the filter hole 102 is located at the bottom of the filter 10.

[0034] The filter hole 102 is arranged on the side wall of the cylindrical shell 11, and the third region 113 is also arranged on the side wall. The filter hole 102 and the third region 113 are arranged on the side wall of the cylindrical shell 11, so that the filter state and the non-filter state can be switched by rotating the cylindrical shell 11 along the axis b of the cylindrical shell 11, that is, the axis b of the cylindrical shell 11 is used as the rotation axis, so as to reduce the space occupied by the state switching and improve the use convenience. The first region 111 where the first inlet 101 is arranged is also arranged on the side wall of the cylindrical shell 11. At least part of the first region 111 where the first inlet 101 is arranged is arranged opposite to the filter hole 102. In the filter state, the first region 111 and the second region 112 are arranged in the vertical direction, and the first region 111 is arranged above the second region 112. Therefore, the flow rate of the fluid flowing from the first inlet 101 to the filter hole 102 in the filter cavity 103 can be improved by using the gravity, and the filtering efficiency can be improved.

[0035] In other embodiments (not shown in the figure), the first inlet can also be arranged on the end wall as the flow inlet of the fluid, which will not be described herein.

[0036] In other embodiments (not shown in the figure), the third region further includes an end wall of the cylindrical shell. For example, the axis of the cylindrical shell can be arranged at an angle with the horizontal plane, so that the end wall can also bear the gravity of the fluid in the filter cavity which has not been filtered. Therefore, the risk of the fluid remaining in the filter cavity flowing out of the filter cavity in the non-filter state can be further reduced, and the cleanliness can be improved.

[0037] In other embodiments, the filter member can also be a prism shell or other shapes.

[0038] In some embodiments, referring to Figure 3 、 Figure 5 , the first region 111, the second region 112 and the third region 113 are arranged in the circumferential direction of the cylindrical shell 11.

[0039] The first region 111 and the second region 112 are arranged along the circumference of the cylindrical shell 11, and at least part of the first inlet 101 is arranged opposite to the filter hole 102, so that when the central axis of the filter hole 102 is arranged at an acute angle or parallel to the vertical line a of the cylindrical shell 11 in the filtering state, the arrangement of at least part of the first inlet 101 opposite to the filter hole 102 can facilitate the use of gravity to increase the flow rate of the fluid flowing from the first inlet 101 to the filter hole 102 in the filtering cavity 103, thereby improving the filtering efficiency; the second region 112 and the third region 113 are arranged along the circumference of the cylindrical shell 11, which facilitates switching between the filtering state and the non-filtering state by rotating along the axis b of the cylindrical shell 11; the first region 111 and the third region 113 are arranged along the circumference of the cylindrical shell 11, which can reduce the risk of the fluid remaining in the filtering cavity 103 flowing out of the filtering cavity 103 through the first inlet 101 without passing through the filter hole 102 in the non-filtering state, thereby improving the cleanliness.

[0040] In some embodiments, the second region 112 extends along the circumference of the cylindrical shell 11 by a first arc value A, and the first region 111 extends along the circumference of the cylindrical shell 11 by a second arc value B, and the sum of the first arc value A and the second arc value B is less than or equal to 180 degrees.

[0041] For example, the sum of the first arc value A and the second arc value B is 90 degrees, 100 degrees, 120 degrees, 135 degrees, 150 degrees, 170 degrees, or 180 degrees, etc. Among them, the third region 113 extends along the circumference of the cylindrical shell 11 by a third arc value C, and the sum of the first arc value A, the third arc value C, and the second arc value B is 360 degrees.

[0042] The larger the third arc value C is, the better the effect of preventing liquid from dripping out of the cylindrical shell 11 in the non-filtering state, so that the sum of the first arc value A and the second arc value B is less than 180 degrees, which facilitates increasing the third arc value C to be greater than or equal to 180 degrees. This arrangement can increase the accommodating space formed by the wall of the side wall of the third region 113 in the non-filtering state, thereby increasing the capacity of the space, improving the capacity of the fluid in the filtering cavity 103, and thereby reducing the risk of the fluid remaining in the filtering cavity 103 flowing out of the filtering cavity 103 in the non-filtering state, thereby improving the cleanliness.

[0043] The greater the third radian value C is, the better the cylindrical shell 11 is in preventing liquid from dripping in the non-filtering state, but the range of the first area 111 and the second area 112 is smaller; the smaller the third radian value C is, the greater the range of the first area 111 and the second area 112 is, which is beneficial to improve the flow rate and thus improve the filtering efficiency, but the cylindrical shell 11 is worse in preventing liquid from dripping in the non-filtering state. Therefore, the third radian value C is set to 180 degrees, which not only facilitates the increase of the accommodating space formed by the wall of the side wall of the third area 113 in the non-filtering state, increases the accommodating amount of the fluid in the filtering cavity 103, and thus reduces the risk of dripping of the fluid in the filtering cavity 103 out of the filtering cavity 103 in the non-filtering state, but also ensures the filtering efficiency of the filter element 10 and improves the user experience.

[0044] In other embodiments (not shown in the figure), the sum of the first radian value and the second radian value can also be greater than 180 degrees, for example, if the sum of the first radian value and the second radian value is equal to 200 degrees, the third radian value corresponds to 160 degrees, and other values can also be selected, which will not be described here.

[0045] In some embodiments, the first radian value A is equal to the second radian value B.

[0046] For example, the first radian value A and the second radian value B are both 50 degrees, 60 degrees, or 90 degrees, or 100 degrees, etc.

[0047] The greater the first radian value A is, the smaller the second radian value B is, and vice versa, so setting the first radian value A equal to the second radian value B can balance the inflow and outflow speeds of the fluid in the filtering cavity 103 to some extent and reduce the risk of excessive accumulation of the fluid in the filtering cavity 103.

[0048] In some embodiments, referring to Figure 2 , Figure 4 , the first radian value A and the second radian value B are both 90 degrees, and the third radian value C is 180 degrees; the axis b of the cylindrical shell 11 is parallel to the horizontal plane; referring to Figure 2 , in the filtering state, the first area 111 and the third area 113, and the second area 112 and the third area 113 are arranged along the horizontal direction, the first area 111 and the second area 112 are arranged along the vertical direction, and the first area 111 is above the second area 112, so that the filtering hole 102 is located at the bottom of the filter element 10; referring to Figure 4 , in the non-filtering state, the first area 111 and the third area 113, and the second area 112 and the third area 113 are arranged along the vertical direction, and the first area 111 and the second area 112 are arranged along the horizontal direction, so that the third area 113 is located at the bottom of the filter element 10, and when the filter element 10 is cleaned, the filter element 10 can be controlled to enter the non-filtering state first.

[0049] In an application scenario, the filter state can be switched to the non-filtering state by rotating the cylindrical shell 11 counterclockwise by 90 degrees around the axis b, and the non-filtering state can be switched to the filtering state by rotating the cylindrical shell 11 clockwise by 90 degrees around the axis b.

[0050] The above arrangement facilitates increasing the capacity of the accommodating space formed by the side wall of the third region 113 in the non-filtering state, and reducing the phenomenon of dripping at the filtering holes 102; and the above arrangement facilitates, in the filtering state, making more filtering holes 102 as large as possible to be directed obliquely downward, while making the first inlet 101 be directed obliquely upward, so as to facilitate as much as possible using the gravity to increase the speed of the fluid flowing into the filtering cavity 103 through the first inlet 101, and to increase the filtering speed of the fluid being filtered and separated at the filtering holes 102, so as to improve the overall filtering efficiency.

[0051] In other embodiments, the arrangement directions between the first region, the third region, and the second region in the filtering state and the non-filtering state can be fine-tuned according to the use requirements, and will not be described again.

[0052] In other embodiments, the first radian value is greater than the second radian value, for example, the first radian value is 100 degrees, and the second radian value is 80 degrees, or the first radian value is 70 degrees, and the second radian value is 60 degrees; or the first radian value is set to be less than the second radian value, so as to reduce the risk of excessive accumulation of fluid in the filtering cavity 103 due to too fast input speed of the fluid caused by too large first inlet.

[0053] In other embodiments, the side wall is divided into a first region, a second region, a third region, and a fourth region, the first region, the fourth region, the second region, and the third region are arranged in sequence along the circumference of the cylindrical shell, the third region and the fourth region are each composed of a wall body of the side wall, the fourth region extends a fourth radian value along the circumference of the cylindrical shell, and the sum of the fourth radian value, the first radian value, and the second radian value is less than or equal to 180 degrees.

[0054] The fourth region is added between the first region and the second region, so as to facilitate spacing the first inlet and the plurality of filtering holes, reduce the risk of mixing the fluid that has not been filtered and the fluid that has been filtered and flows out of the filtering cavity 103, and improve the filtering effect.

[0055] In some embodiments, the filtering holes 102 extend along the circumference of the cylindrical shell 11, and the plurality of filtering holes 102 are arranged along the axis of the cylindrical shell 11.

[0056] A plurality of filtering holes 102 extending along the circumference of the cylindrical shell 11 are arranged axially along the cylindrical shell 11 on the side wall of the cylindrical shell 11 to form a filtering grid, which facilitates the isolation of filtering residues such as large-particle solids in the filtering cavity 103, and the structure of the filtering grid is simple, which facilitates the reduction of the difficulty of the production process.

[0057] In other embodiments, the filtering grid can be structurally adjusted according to product design requirements, for example, the filtering holes are arranged to extend axially along the cylindrical shell, and a plurality of filtering holes are arranged circumferentially along the cylindrical shell to form a filtering grid.

[0058] In some embodiments, there is a gap between the bottom wall of the shell assembly 20 and the filtering element 10, which facilitates filtering. For example, in an application scenario, the filtering element 10 includes a cylindrical shell 11, and the filtering state and the non-filtering state can be switched by controlling the rotation of the cylindrical shell 11 along its axis b; the two ends of the cylindrical shell 11 abut the two ends of the bottom wall of the shell assembly 20 to support the cylindrical shell 11, so that there is a filtering gap between the bottom wall of the shell assembly 20 and the cylindrical shell 11; and the outlet 202 is arranged on the bottom wall of the shell assembly 20.

[0060] In some embodiments, the shell assembly 20 includes a first shell 211 and a second shell 212, the first shell 211 is provided with the second inlet 201, and the second shell 212 is provided with the outlet 202; the first shell 211 and the second shell 212 enclose a containing cavity 203, and the inner side wall of the second shell 212 is spaced apart from the side wall of the cylindrical shell 11.

[0061] Specifically, the first shell 211 and the second shell 212 jointly enclose the containing cavity 203, which facilitates the assembly of the base station and improves the convenience of cleaning and other operations on the filtering element 10; in an application scenario, the outlet 202 is arranged at the bottom of the second shell 212, and the two ends of the second shell 212 abut or are connected with the two ends of the cylindrical shell 11, so that the inner side wall of the second shell 212 is spaced apart from the side wall of the cylindrical shell 11, i.e., there is a gap between the bottom of the second shell 212 and the cylindrical shell 11, which facilitates filtering.

[0062] In some embodiments, the filtering element 10 includes a cylindrical shell 11, and the side wall of the cylindrical shell 11 is divided into a first region 111, a second region 112 and a third region 113 arranged circumferentially along the cylindrical shell 11; the sum of the first arc value A of the first region 111 of the side wall of the cylindrical shell 11, in which the first inlet 101 is arranged, extending along the circumference of the cylindrical shell 11, and the second arc value B of the second region 112 of the side wall of the cylindrical shell 11, in which the filtering holes 102 are arranged, extending along the circumference, is less than or equal to 180 degrees; and the second inlet 201 is located on one side of the plumb line a of the cylindrical shell 11.

[0063] The plumb line a is a line connecting the center of gravity of the object and the center of gravity of the earth, and is a gravitational direction line of the earth's gravitational field.

[0064] Since the central axis of the filter hole 102 is arranged at an acute angle or parallel to the plumb line a of the filter element 10 in the filtering state, that is, the filter hole 102 is directed to the directly downward or obliquely downward, and at least part of the filter hole 102 is located at the bottom of the filter element 10, and the sum of the first arc value A and the second arc value B is less than or equal to 180 degrees, arranging the second inlet 201 on one side of the plumb line a of the cylindrical shell 11 facilitates reducing the distance between the first inlet 101 and the second inlet 201, and facilitating the fluid flowing into the second inlet 201 to flow into the first inlet 101 more quickly.

[0065] For example, in an application scenario, when the first area 111 and the second area 112 are arranged in the vertical direction in the filtering state, and the first area 111 is above the second area 112, and the first area 111 and the third area 113, and the second area 112 and the third area 113 are arranged in the horizontal direction, since the sum of the first arc value A and the second arc value B is less than or equal to 180 degrees, the first inlet 101 is located on one side of the plumb line a of the cylindrical shell 11, and therefore arranging the second inlet 201 on one side of the plumb line a of the cylindrical shell 11 facilitates the fluid flowing into the second inlet 201 to flow into the first inlet 101 more quickly; therefore, in some embodiments, the second inlet 201 can also be arranged on one side of the plumb line a of the cylindrical shell 11, and the first inlet 101 and the second inlet 201 are located on the same side of the plumb line a of the cylindrical shell 11 in the filtering state.

[0066] In some embodiments, the axial direction of the outlet 202 is arranged at an acute angle to the direction of gravity, facilitating the use of gravity to improve the flow rate of the filtered fluid out of the outlet 202; in some embodiments, the axial direction of the outlet 202 is arranged parallel to the direction of gravity, which can further improve the flow rate.

[0067] In some embodiments, the first shell 211 comprises a first main body part 2111 and a first flow guide part 2112, and the second shell 212 comprises a second main body part 2121 and a second flow guide part 2122. The first main body part 2111 and the second main body part 2121 form a cylindrical structure, and the cylindrical structure forms a receiving cavity 203 for accommodating the filter element 10. The first flow guide part 2112 is arranged on the side wall of the first main body part 2111 away from the second main body part 2121.

The second flow guide part 2122 is arranged on the side wall of the second main body part 2121 away from the first main body part 2111. One end of the second flow guide part 2122 is in communication with the receiving cavity 203, and the other end is provided with the outlet 202. One end wall of the cylindrical structure forms an opening, which facilitates adjusting the state switching of the filter element 10 through the opening or taking out the filter element 10 in the non-filtering state for cleaning through the opening.

[0068] In some embodiments, the first flow guide part 2112 is detachably arranged with the first main body part 2111. According to different host machines, a corresponding first flow guide part 2112 can be selected to enable the pollution discharge port of the host machine to be in communication with the adaptive second inlet 201, so as to guide the fluid discharged from the host machine into the filtering cavity 103.

[0069] In some embodiments, the base station further comprises a driving assembly in transmission connection with the cavity wall of the filtering cavity 103. The driving assembly can drive the cavity wall to change the position state, so as to realize the state switching between the filtering state and the non-filtering state.

In addition, the filter element 10 has a filtering state and a non-filtering state which can be switched. When the pollution filtering is not needed, the filter element 10 is in the non-filtering state, which can reduce the risk of dripping at the filter hole 102 of the filter element 10 during the process of taking out the filter element 10 for cleaning, and improve the hygiene of the cleaning operation of the filter element 10.

In some embodiments, multiple host machines can share the same base station, and the host machine includes a sweeping machine, a washing machine, a drying and washing integrated machine, a sweeping and mopping integrated machine, etc., and the specific implementation is not limited.

[0076] In some application scenarios, the base station and the host machine are physically connected, the second inlet 201 is communicated with the sewage outlet of the host machine, the first inlet 101 is communicated with the sewage outlet of the host machine through the second inlet 201, the fluid enters the first inlet 101 through the second inlet 201, then is filtered in the filter cavity 103, the filtered residue is left in the filter cavity 103, and the fluid flows out to the containing cavity 203 through the filter hole 102, and then flows out to the external environment through the outlet 202; in some application scenarios, the outlet 202 is communicated with the external sewage system, so as to directly discharge the filtered sewage and other fluids to the sewage system.

[0077] In the cleaning system, the above-mentioned base station is used, so as to realize the solid-liquid separation treatment of the dirt, and improve the cleanliness and operation convenience of the cleaning system.

[0078] Different from the prior art, the filter element of the present application can be used to filter fluid, the fluid enters the filter cavity from the first inlet, then flows to the filter hole and is filtered, the filtered residue is left in the filter cavity, and the filtered fluid flows out of the filter cavity; the filter element is rotatably arranged relative to the shell assembly, so as to adjust the relative position of the filter element and the shell assembly in different states (such as filtering state and non-filtering state), so that the filter hole and the outlet can be selectively communicated, thereby improving the working state diversity of the filter, facilitating the user to switch the working state of the filter, and improving the operation convenience.
