[0028] Typical embodiments embodying the features and advantages of the present invention are described in detail in the following description. It should be understood that the present invention is capable of various variations in different embodiments without departing from the scope of the present invention, and that the descriptions and illustrations are intended to be illustrative rather than limiting.

[0029] In order to further illustrate the principle and structure of the present invention, preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0030] The present application provides a cleaning device, which can be a base station. The base station is used in conjunction with a cleaning robot. The base station is used to maintain the cleaning robot. Specifically, the base station can be used to charge the cleaning robot, clean the mopping parts of the cleaning robot, and realize functions such as air drying and dust collection.

[0031] In addition, the cleaning equipment provided in this application can also be a cleaning robot, which can be used commercially or at home. Specifically, it can be an automatic device such as a sweeping robot, a mopping robot, a floor washing robot, a sweeping and mopping machine, or a semi-automatic device such as a handheld one.

[0032] The present application provides a cleaning device, which includes a main body and a filter. The filter is arranged on the main body and is used to filter liquid.

[0033] See Figures 1 to 5 In one embodiment of the cleaning device of the present application, a filter 10 is provided with a receiving chamber 101 therein, and a liquid inlet 102 and a liquid outlet 103 are provided on the filter 10, which are in communication with the receiving chamber 101. A filtration channel is provided in the receiving chamber 101 of the filter 10, and the length of the flow path of the liquid in the filtration channel is greater than the height distance between the liquid inlet 102 and the liquid outlet 103.

[0034] In the cleaning device of this embodiment, the liquid inlet 102 in the filter 10 allows sewage to enter the accommodating chamber 101, allowing the sewage to circulate within the filter channel. The length of the sewage's flow path within the filter channel is greater than the height distance between the liquid inlet 102 and the liquid outlet 103. By increasing the sewage's flow path within the filter 10, the sewage's flow rate is reduced, allowing the filter 10 to effectively filter the sewage and improving its filtration efficiency. The effective filtration of the sewage by the filter 10 prevents impurities from accumulating in the sewage, which can cause the cleaning device to become smelly and difficult to clean, thereby improving the user experience.

[0035] In this embodiment, the filter 10 includes a filter cartridge 11, which includes a cartridge body 111 and a flow guide 112. The cartridge body 111 is cylindrical in structure, and its interior forms a receiving chamber 101. The liquid inlet 102 and the liquid outlet 103 are located at the top and bottom of the cartridge body 111, respectively. The flow guide 112 is disposed within the cartridge body 111 and connected to the inner wall of the cartridge body 111, forming a filtration channel within the receiving chamber 101. Liquid entering the receiving chamber 101 through the liquid inlet 102 flows along the surface of the flow guide 112.

[0036] The guide member 112 of this embodiment is spiral-shaped, that is, it spirals from top to bottom along the height of the box body 111. The surface of the guide member 112 forms a filtration channel, and liquid flows along the surface of the guide member 112, so that the length of the liquid flow path is greater than the height distance between the liquid inlet 102 and the liquid outlet 103.

[0037] It can be understood that, in addition to the spiral guide member 112 shown in this embodiment, the guide member 112 can also have other structural forms, such as stepped, inclined ladder, wavy, etc., as long as the surface of the guide member 112 is an inclined surface and the flow path of the liquid on the surface of the guide member 112 is greater than the height distance between the liquid inlet 102 and the liquid outlet 103.

[0038] In this embodiment, the box body 111 includes a box body 1111 and a cover 1112. The top of the box body 1111 is provided with an opening, and the cover 1112 is provided to cover the opening of the box body 1111. The space enclosed by the cover 1112 and the box body 1111 constitutes the accommodating chamber 101. The drainage member 112 is provided inside the box body 1111 and connected to the inner wall of the box body 1111.

[0039] The liquid inlet 102 is provided on the side wall of the cover 1112, and the liquid can enter the accommodating cavity 101 of the box body 111 through the liquid inlet 102. Figure 6 The filter cartridge 11 of this embodiment further includes a baffle 113, which is protruding from the inner wall of the cover 1112 and disposed near the liquid inlet 102. The baffle 113 includes a stop surface 1131, which is used to stop the liquid and is disposed toward the liquid inlet 102.

[0040] When liquid enters the accommodating cavity 101 of the box body 111 from the liquid inlet 102, the stopping surface 1131 of the blocking piece 113 can stop the liquid at the liquid inlet 102 so that all the liquid is gathered on the guide member 112, and the liquid flows in the accommodating cavity 101 along the surface of the guide member 112.

[0041] In this embodiment, if Figure 7 and Figure 8 As shown, the filter channel formed on the surface of the flow guide 112 has a starting end and a terminal end. The liquid flows through the filter channel from the starting end to the terminal end. In this embodiment, the liquid inlet 102 is arranged corresponding to the starting end. This arrangement allows the liquid to flow directly from the starting end to the terminal end after entering the accommodating chamber 101 through the liquid inlet 102, thereby ensuring an effective flow path for the liquid in the accommodating chamber 101.

[0042] The guide member 112 is spirally arranged in a 360° direction inside the box body 111. This arrangement can extend the length of the filter channel formed on the surface of the guide member 112 as much as possible, thereby effectively extending the flow path of the liquid in the accommodating cavity 101.

[0043] Furthermore, if Figures 1 to 5 As shown, the filter 10 of this embodiment further includes a filter screen 12, which is disposed below the housing 111. The filter screen 12 is used to filter the liquid and has a plurality of spaced filter holes 121 to remove large particles of impurities from the liquid. The mesh size and diameter of the filter holes 121 on the filter screen 12 can be adjusted based on the amount of impurities in the liquid and the desired filtering effect.

[0044] The liquid enters the accommodating chamber 101 from the liquid inlet 102 of the filter 10, flows along the filtering channel formed on the surface of the guide member 112, and then flows out from the liquid outlet 103 of the filter 10 to the filter screen 12 below, thereby being filtered by the filter screen 12 to remove large particles of impurities.

[0045] In this embodiment, the flow guide 112 is provided with a plurality of drainage holes, which are evenly spaced along the flow path. The filter 10 has a plurality of liquid outlets 103, which are evenly spaced at the bottom of the box body 111.

[0046] When the liquid flows in the filter channel formed on the surface of the drainage member 112, under the action of multiple drainage holes and multiple liquid outlets 103, the liquid can be evenly covered on the filter mesh 12, so that the filter mesh 12 can effectively filter the sewage and ensure the filtering effect of the filter 10 on the sewage.

[0047] Furthermore, the filter 10 of this embodiment also includes a housing 13, which includes a first shell 131 and a second shell 132 connected vertically. The first shell 131 is a cylindrical structure with openings at both ends and a hollow interior. The second shell 132 is a cylindrical structure with an opening at the top. The top opening of the second shell 132 constitutes a filter inlet 1321, and the bottom of the second shell 132 is provided with a filter outlet 1322.

[0048] The first shell 131 is arranged on the top of the second shell 132 so that the filter inlet 1321 of the second shell 132 is connected to the liquid outlet 103 on the filter box 11, so that the sewage filtered by the filter screen 12 enters the second shell 132 through the filter inlet 1321.

[0049] In this embodiment, a raised portion 1311 is formed on the periphery of the top opening of the first housing 131, and a receiving groove 1312 is provided at the bottom open end of the first housing 131. A latching groove 1113 is provided at the bottom of the cover 1112 of the box body 111, and the raised portion 1311 is latched into the latching groove 1113, thereby detachably connecting the filter box 11 to the first housing 131 and accommodating the box body 1111 within the interior of the first housing 131.

[0050] An annular support portion 1313 is provided within the first housing 131. The support portion 1313 protrudes from the inner wall of the first housing 131 and is positioned near the bottom of the first housing 131. The filter 12 is mounted on the support portion 1313 and positioned below the housing 111. The detachable connection between the filter cartridge 11 and the first housing 131 facilitates removal of the filter cartridge 11 from the first housing 131, facilitating easy replacement of the filter 12.

[0051] In this embodiment, the filter 10 further includes a plurality of filter elements 14 , which are arranged in layers in a direction extending from the filter inlet 1321 to the filter outlet 1322 .

[0052] The filter element 14 of this embodiment is a membrane-like structure made of filter material to filter the liquid. Multiple filter elements 14 are arranged layer by layer within the second housing 132, filtering the liquid layer by layer to enhance the filtration effect, removing impurities such as suspended matter, particulate matter, and colored matter from the wastewater, thereby filtering the wastewater into clean water.

[0053] In this embodiment, the filter 10 includes three layers of filter elements 14. From top to bottom, the first layer of filter elements 14 can filter visible suspended solids, rust, sediment, and other substances in the sewage; the second layer of filter elements 14 can filter odors, oxides, and odors in the sewage; and the third layer of filter elements 14 can remove bacteria, viruses, and inorganic substances in the sewage.

[0054] The filter 10 of this embodiment also includes a mesh barrier 15. This barrier 15 is positioned within the second housing 132 and below the third filter membrane. The filter 12 prevents the filter material from escaping with the liquid, ensuring the integrity of the membrane's overall structure and ensuring its filtration effectiveness.

[0055] The top periphery of the second housing 132 is snap-fitted into the receiving groove 1312 in the first housing 131, so that the second housing 132 is detachably connected to the first housing 131. By providing a detachable connection between the first housing 131 and the second housing 132, it is easier to remove the second housing 132 from the first housing 131, thereby facilitating replacement of the filter membrane.

[0056] In this embodiment, the filter outlet 1322 is located near the center of the bottom of the second housing 132. The filter 10 includes a plurality of ribs 16, which are protruding from the bottom inner wall of the second housing 132. The ribs 16 are spaced apart along the circumference of the filter outlet 1322, and a guide groove 161 is formed between two adjacent ribs 16 and the bottom inner wall of the second housing 132. The guide groove 161 is inclined toward the filter outlet 1322.

[0057] After entering the second housing 132, the sewage is filtered into clean water by the multi-layer filter element 14. The clean water is collected through the guide groove 161 and guided to the filter outlet 1322. By tilting the guide groove 161, the clean water can be better guided out.

[0058] In this embodiment, the cleaning device further includes a dirty liquid collection box, which is arranged on the main body.

[0059] A cleaning cavity is provided inside the dirty liquid collection box. A first inlet and a first outlet are provided on the dirty liquid collection box. Both the first inlet and the first outlet are communicated with the cleaning cavity.

[0060] One side of the dirty liquid collection box is provided with an opening connected to the cleaning chamber, and the cleaning robot can enter the cleaning chamber through the opening of the dirty liquid collection box, and the mopping and wiping parts of the cleaning robot can be cleaned by clean water in the cleaning chamber. When the mopping and wiping parts are cleaned, sewage will be generated in the dirty liquid collection box.

[0061] The cleaning device of this embodiment also includes a clean water tank having a second inlet and a second outlet. The first outlet of the dirty liquid collection tank is connected to the liquid inlet 102 of the filter 10, and the filter outlet 1322 of the filter 10 is connected to the second inlet of the clean water tank. The second outlet of the clean water tank is connected to the first inlet of the dirty liquid collection tank, so that the dirty water in the dirty liquid collection tank enters the filter 10, is filtered into clean water, enters the clean water tank, and then enters the dirty liquid collection tank from the clean water tank for cleaning the mopping parts, thus achieving wastewater recycling.

[0062] By filtering wastewater into clean water for recycling, the cleaning equipment can be operated for a longer period of time, eliminating the need for frequent manual additions to the clean water tank and conserving water. Furthermore, filtering wastewater through the filter 10 can address the problem of internal odors in the cleaning equipment. Furthermore, recycling wastewater from the wastewater collection tank eliminates the need for manual dumping, making the cleaning equipment more intelligent. Furthermore, the clean water tank can be increased in size, increasing the amount of clean water it can hold, ensuring longer-lasting operation and enhancing the user experience.

[0063] In the cleaning device of this embodiment, the liquid inlet in the filter allows sewage to enter the accommodating chamber, allowing the sewage to circulate within the filter channel. The length of the sewage's flow path within the filter channel is greater than the height distance between the liquid inlet and the liquid outlet. By increasing the sewage's flow path within the filter, the sewage's flow rate is reduced, allowing the filter to effectively filter the sewage and improving its filtration effectiveness. This effective filtration of sewage by the filter prevents impurities from accumulating in the sewage, which can cause the cleaning device to become smelly and difficult to clean, thereby improving the user experience.

[0064] While the present invention has been described with reference to several exemplary embodiments, it should be understood that the terms used are intended to be illustrative and exemplary rather than restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope of the appended claims. All changes and modifications that fall within the scope of the claims or their equivalents are intended to be covered by the appended claims.
