[0036] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the technical solutions provided by the present application. However, it will be apparent to one of ordinary skill in the art that the technical solutions provided by the present application can be practiced without one or more of these specific details.

[0037] It is to be understood that the terminology used herein is for the purpose of describing specific embodiments only and is not intended to be limiting of example embodiments in accordance with the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and / or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0038] In accordance with the present application, example embodiments will now be described in detail with reference to the accompanying drawings. These example embodiments, however, can be implemented in various forms and should not be construed as being limited to the embodiments set forth herein. It is to be understood that the embodiments are provided only to make the disclosure complete and to fully convey the concept of the example embodiments to those skilled in the art.

[0039] An optional embodiment of the first aspect of the present application provides a recovery tank 140, and an optional embodiment of the second aspect of the present application provides a cleaning device, in particular, a handheld cleaning device or a self-moving cleaning device, the cleaning device comprising a device main body, the recovery tank 140 being detachably connected to the device main body, the recovery tank 140 being mounted on the device main body for collecting the to-be-processed medium on the to-be-cleaned surface when the cleaning device is working, such as collecting sewage and solid impurities, and the recovery tank 140 can be detached from the device main body when the cleaning device completes the cleaning work, and the to-be-processed medium can be poured out. Specifically, the handheld cleaning device can be a handheld scrubber, a handheld floor polishing robot, a handheld weeding robot, or other cleaning devices that meet the requirements, and the self-moving cleaning device can be a sweeping and mopping integrated machine or other cleaning devices that meet the requirements. For ease of description, the technical solutions of the present disclosure are described taking a handheld scrubber as an example.

[0040] Further, taking the cleaning device as a handheld scrubber as an example, as shown in Figure 5 The cleaning device comprises a surface walking part 150, a vertical part 160, and a recovery tank 140. The surface walking part 150 is in contact with the to-be-cleaned surface to clean the to-be-processed medium remaining on the to-be-cleaned surface. The vertical part 160 is connected to the surface walking part 150. The recovery tank 140 is detachably mounted on the vertical part 160. When the surface walking part 150 is working, the vertical part 160 is used to move the surface walking part 150 to clean the to-be-cleaned surface and collect the to-be-processed medium into the recovery tank 140. When the cleaning is completed, the recovery tank 140 can be detached from the vertical part 160, and the collected to-be-processed medium can be poured out. Specifically, the cleaning object of the cleaning device includes ceramic tiles, floors, cement floors, glass surfaces, and other surface objects with flat surfaces that can be washed with water.

[0041] In an optional embodiment provided by the present application, as shown in Figure 1 The recovery bucket 140 includes the upper cover 110, the filter part 120 and the pollution inlet channel 131, wherein the pollution inlet channel 131 is communicated with the surface to be cleaned, so that the medium to be treated on the surface to be cleaned is received into the recovery bucket 140 through the pollution inlet channel 131. The medium to be treated includes liquid and solid, the liquid is sewage, and the solid is hair, sheet, strip or large particle dust, etc.

[0042] The filter part 120 is provided with a plurality of filter holes 121 to separate the solid and liquid of the medium to be treated. The filter part 120 is detachably connected with the upper cover 110, and a filter space is formed between the filter part 120 and the upper cover 110. The pollution inlet channel 131 is arranged in the filter part 120 and includes a channel outlet 132 located in the filter space. Therefore, after the medium to be treated on the surface to be cleaned is filtered by the filter holes 121 of the filter part 120 through the channel outlet 132 of the pollution inlet channel 131, the solid medium is located on one side of the filter part 120 facing the upper cover 110, and the liquid medium is located on the other side of the filter part 120 away from the upper cover 110. Thus, the solid and liquid separation of the medium to be cleaned is realized, which reduces the possibility that the solid impurities in the solid-liquid mixture are adhered and absorbed on the inner wall of the recovery bucket and cannot be completely poured out. Meanwhile, the possibility that the solid impurities in the solid-liquid mixture poured out block the liquid discharge pipeline is reduced, which is beneficial to improve the cleanliness of the recovery bucket 140 and provide guarantee for the subsequent treatment of the liquid medium and the solid medium, thereby improving the cleaning efficiency.

[0043] Further, the channel outlet 132 of the pollution inlet channel 131 is located above the filter part 120, which increases the volume of the filter space between the upper cover 110 and the filter part 120. A smaller filter space is not conducive to the flow of the solid-liquid mixture, and a larger filter space is conducive to the flow of more solid-liquid mixture, thereby being conducive to improving the filtering efficiency. Moreover, the channel outlet 132 is located above the filter part 120, which increases the distance between the channel outlet 132 and the filter part 120, that is, increases the flow distance of the solid-liquid mixture falling from the channel outlet 132 to the filter part 120. Such a design can increase the impact force of the solid-liquid mixture flowing out of the channel outlet 132 and falling to the filter part 120 on the filter part 120, thereby being conducive to the flow of the liquid and moving the solid medium blocking the filter holes 121 on the filter part 120 to improve the filtering efficiency. In addition, the problem that the solid medium blocks the filter holes 121 and the impact force of the solid-liquid mixture falling to the filter part 120 on the filter part 120 is small, thereby reducing the filtering efficiency, is avoided. That is, the channel outlet 132 located above the filter part 120 can further increase the filtering efficiency and improve the user's satisfaction.

[0044] Meanwhile, since the solid-liquid mixture in the dirt inlet channel 131 flows out of the channel outlet 132 under the suction of the gas, the distance between the channel outlet 132 and the bottom of the upper cover 110 is short by locating the channel outlet 132 above the filter part 120. Such an arrangement can cause the solid-liquid mixture to hit the bottom of the upper cover 110 after flowing out of the channel outlet 132 of the dirt inlet channel 131 and before falling, thereby improving the gas-liquid separation efficiency, avoiding the problem of high liquid content in the gas damaging other components of the cleaning device, and reducing the failure rate of the cleaning device and improving the reliability of the cleaning device. It can be understood that in the case of the same size of the filter part 120, the channel outlet 132 can be located above the filter part 120 to be as close to the upper cover 110 as possible. In this way, the height of the filter part 120 in the recovery bucket can be increased to ensure that the filter part 120 will not be submerged by the liquid level of the sewage when the liquid in the recovery bucket is full, further ensuring the reliability of the filter part 120 and improving the user's satisfaction.

[0045] Further, the filter part 120 is detachably connected to the upper cover 110. Since the solid medium is received to the side of the filter part 120 facing the upper cover 110, when the filter part 120 contains a large amount of solid medium, the filter part 120 can be detached from the upper cover 110 to dump the solid medium, and then the relatively clean filter part 120 can be installed on the upper cover 110. The operation is simple and convenient, and the processing speed of the solid medium is improved. At the same time, the detachable connection of the filter part 120 and the upper cover 110 facilitates the cleaning and maintenance of the filter part 120, and improves the user's satisfaction.

[0046] It can be understood that the above-mentioned filter part 120 can achieve solid-liquid separation of the medium to be treated, specifically, the solid-liquid mixed medium to be treated flows through the plurality of filter holes 121 of the filter part 120 to achieve solid-liquid separation. Here, the separated solid medium refers to solid medium with a larger size, and solid medium with a smaller size will flow into the side of the filter part 120 away from the upper cover 110 along with the liquid, i.e., the solid-liquid separation refers to separating the solid medium with a larger size from the solid medium with a smaller size and the liquid. That is, the separated liquid includes solid medium with a smaller size. Specifically, the larger size can be any debris with a diameter or length greater than or equal to 0.5mm to 6mm, preferably any debris such as 3mm, and the smaller size can be any debris with a diameter or length less than 0.5mm, such as any debris such as 0.3mm. Further, by reasonably setting the diameter or length of the filter hole 121, solid medium with different values of larger size and smaller size and liquid can be separated. The number of filter holes 121 is a plurality, which is conducive to improving the filtering efficiency of the filter part 120.

[0047] In this embodiment, as shown in Figure 1 The recycling bucket 140 further comprises a bucket body 130, which comprises an inner shell 134 and an outer shell 135, the inner shell 134 is formed with a pollution inlet channel 131, the channel outlet 132 of the pollution inlet channel 131 is communicated with the accommodating cavity, and the pollution inlet channel 131 further comprises a channel inlet 133 located outside the accommodating cavity, that is, the to-be-cleaned surface of the to-be-processed medium can be accommodated into the accommodating cavity through the channel inlet 133, the pollution inlet channel 131 and the channel outlet 132.

[0048] The filter part 120 is located in the accommodating cavity, and the channel outlet 132 is located between the filter part 120 and the upper cover 110, so that the solid-liquid mixed to-be-processed medium is filtered through the plurality of filter ports, and then the liquid medium flows between the filter part 120 and the bucket body 130, and the solid medium is accommodated between the filter part 120 and the upper cover 110, so as to realize the solid-liquid separation of the to-be-processed medium. Since the upper cover 110 and the bucket body 130 are detachably connected, the upper cover 110 and the bucket body 130 can be separated, and the liquid medium in the bucket body 130 can be poured out. Since the liquid medium in the bucket body 130 is the liquid medium after solid-liquid separation, the possibility that the solid impurities are adhered and adsorbed on the inner wall of the bucket body 130 and cannot be poured out completely can be reduced, and the problem that the solid impurities block the liquid discharge pipeline when the solid-liquid mixed to-be-processed medium is poured out at the same time can be avoided, so that the cleaning efficiency is greatly improved. It can be understood that for the treatment of the solid medium, the filter part 120 can be detached from the upper cover 110 to pour out the solid impurities, which is simple in operation and convenient in cleaning. Among them, Figure 1 The direction indicated by the dotted line head is the flow direction of the to-be-processed medium.

[0049] Further, the inner shell 134 of the bucket body 130 is formed with the channel inlet 133 of the pollution inlet channel 131 at one end away from the upper cover 110, and the inner shell 134 of the bucket body 130 is formed with the channel outlet 132 of the pollution inlet channel 131 at one end close to the upper cover 110, the inner shell 134 extends from the channel inlet 133 to the channel outlet 132, and forms the pollution inlet channel 131 communicated with the channel inlet 133 and the channel outlet 132. The outer shell 135 is arranged outside the inner shell 134 and is sealingly connected with the inner shell 134 at the side of the channel inlet 133, so as to form the bucket body 130 with the accommodating cavity.

[0050] In some possible implementation embodiments provided by the present application, as shown in Figure 2 and Figure 3As shown, the upper cover 110 includes a cover body 111, which is detachably connected with the shell 135, and is provided with a suction port 112 in communication with the accommodating cavity. The suction port 112 can enable the medium to be cleaned to be sucked to the passage outlet 132 through the passage inlet 133 under the action of the fluid, and then flow into the filter part 120. It can be understood that the cleaning device also includes a suction fan, which is in communication with the suction port 112 and provides a suction airflow when working. Under the action of the suction airflow, the medium to be cleaned on the surface to be cleaned is sucked to the passage outlet 132 through the passage inlet 133, and then flows through the plurality of filter holes 121 of the filter part 120 to realize solid-liquid separation.

[0051] Further, the suction port 112 can also be provided with a filter screen 114 connected with the cover body 111 to filter the fluid flowing through the suction port 112, such as separating the fluid and the solid, to avoid the solid medium in the recovery barrel 140 being output to the outside of the suction port 112 with the suction airflow and causing failure of other components of the cleaning device. The provision of the filter screen 114 is beneficial to enabling the medium to be treated sucked by the suction airflow to be all stored in the recovery barrel 140, further improving the thoroughness and effectiveness of the recovery barrel 140 in storing the medium to be treated, and improving the cleaning performance and reliability of the cleaning device.

[0052] Further, as shown in Figure 2 and Figure 3 The upper cover 110 also includes a bracket 113 provided on one side of the cover body 111 facing the passage outlet 132 and located on one side of the passage outlet 132 close to the shell 135. The bracket 113 is detachably connected with the filter part 120. Such a configuration enables the passage outlet 132 of the pollution inlet passage 131 to be located at the upper part of the filter part 120, i.e., the filter part 120 is sleeved on the outside of the pollution inlet passage 131, and the passage outlet 132 and the filter part 120 have a certain flow space, so that the medium to be treated discharged through the passage outlet 132 of the pollution inlet passage 131 can flow through the filter holes 121 of the filter part 120 under the action of gravity to realize solid-liquid separation. That is, by reasonably arranging the positions of the bracket 113 and the passage outlet 132 of the pollution inlet passage 131, the filter space between the upper cover 110 and the filter part 120 is large, thereby ensuring that the filter part 120 has good filtering effect and high filtering efficiency, providing protection for subsequent treatment of liquid medium and solid medium, and improving user satisfaction.

[0053] In the above embodiment, as shown in Figure 3 and Figure 4As shown, one of the upper cover 110 and the filter part 120 is provided with a limiting part, and the other is provided with a positioning part matched with the limiting part. The filter part 120 is mounted on the upper cover 110 and connected with the upper cover 110, or separated from the upper cover 110 to be detached from the upper cover 110, by the contact or separation of the limiting part and the positioning part. That is, the limiting part and the positioning part are provided to facilitate the installation and disassembly of the filter part 120, and to meet the different functional requirements of the filter part 120 for solid-liquid separation or pouring of solid medium, and to facilitate the use of the user.

[0054] Further, one of the limiting part and the positioning part can be arranged on the support 113 of the upper cover 110 to increase the volume of the filtering space. Specifically, the limiting part is arranged on the support 113, and the positioning part is arranged on the filter part 120, or the limiting part is arranged on the filter part 120, and the positioning part is arranged on the support 113. The different arrangement positions of the limiting part and the positioning part can meet the different structural requirements of the limiting part and the positioning part, and expand the use range of the product.

[0055] In this embodiment, on the one hand, the limiting part includes a magnetic part, and the positioning part includes a magnetic attraction part. When the filter part 120 needs to be mounted on the support 113 of the upper cover 110, the filter part 120 is moved towards the support 113. The filter part 120 is fixed to the support 113 due to the mutual attraction of the magnetic part and the magnetic attraction part, and then the filter part 120 is mounted on the support 113. When the filter part 120 needs to be separated from the support 113 of the upper cover 110 for cleaning, maintenance, or pouring of solid medium, the filter part 120 is moved away from the support 113. The magnetic part and the magnetic attraction part are separated by overcoming the magnetic attraction force, and then the filter part 120 is detached from the support 113. The arrangement of the magnetic part and the magnetic attraction part facilitates the installation and disassembly of the filter part 120, is simple to operate, and is easy to install and beneficial to production. Specifically, the magnetic part can be a magnet, a magnetic steel, or other magnetic parts meeting the requirements. The magnetic attraction part can be a metal part or other material parts meeting the requirements, for example, the magnetic attraction part is a metal sheet.

[0056] In another aspect, the limiting portion comprises a hook, and the positioning portion comprises a slot. When the filter portion 120 needs to be installed on the support 113 of the upper cover 110, the filter portion 120 is moved towards the support 113, and the hook and the slot are contacted and clamped, so that the filter portion 120 is fixed on the support 113, and then the filter portion 120 is installed on the support 113. When the filter portion 120 needs to be separated from the support 113 of the upper cover 110 for cleaning, maintenance, and pouring of solid medium, the hook is separated from the slot, and then the filter portion 120 is moved away from the support 113, so that the filter portion 120 is detached from the support 113. The hook and the slot are arranged to facilitate the installation and removal of the filter portion 120, and the operation is simple. In addition, the hook and the slot are easy to process, and the cost is low.

[0057] In another aspect, the limiting portion comprises a hook, and the positioning portion comprises a slot. When the filter portion 120 needs to be installed on the support 113 of the upper cover 110, the filter portion 120 is moved towards the support 113, and the hook and the slot are contacted and clamped, so that the filter portion 120 is fixed on the support 113, and then the filter portion 120 is installed on the support 113. When the filter portion 120 needs to be separated from the support 113 of the upper cover 110 for cleaning, maintenance, and pouring of solid medium, the hook is separated from the slot, and then the filter portion 120 is moved away from the support 113, so that the filter portion 120 is detached from the support 113. The hook and the slot are arranged to facilitate the installation and removal of the filter portion 120, and the operation is simple. In addition, the hook and the slot are easy to process, and the cost is low.

[0058] It can be understood that the limiting portion and the positioning portion can also be other structures that meet the requirements, as long as the connection and separation of the filter portion 120 and the support 113 can be achieved. The present application does not list them one by one.

[0059] In some possible implementation embodiments provided by the present application, the filter part 120 comprises a bottom plate 122 and a side plate 123, the bottom plate 122 is provided with a mounting hole 127, the inlet channel 131 is arranged in the mounting hole 127, and the side plate 123 is connected with the bottom plate 122, that is, the side plate 123 and the bottom plate 122 are connected and jointly enclose the filter space with the inlet channel 131, the bracket 113 and the cover body 111. One of the limiting part and the positioning part is arranged on the side plate 123 and used for detachably connecting with the bracket 113 of the upper cover 110. The channel outlet 132 is located in the filter space formed by the bottom plate 122, the side plate 123 and the upper cover 110 and above the side plate 123, which can increase the distance of the to-be-processed medium flowing out of the channel outlet 132 from falling to the bottom plate 122, and further increase the impact force of the solid-liquid mixture flowing out of the channel outlet 132 from falling to the bottom plate 122 on the bottom plate 122. The greater impact force is conducive to increasing the flow speed of the liquid and can move the solid medium blocked at the filter hole 121 away, and further improve the thoroughness of the liquid flowing through the filter part 120. That is, the greater filter space is conducive to the flow of the medium, the channel outlet located above the side plate 123 can make most or all of the to-be-processed medium flowing out of the channel outlet 132 flow through the filter part 120, ensure the good solid-liquid separation effect of the filter part 120, be conducive to improving the filtering efficiency and ensuring the good filtering effect, and improve the satisfaction of the user in use.

[0060] The filter hole 121 is arranged at least on the bottom plate 122, that is, the filter hole 121 can be arranged on the bottom plate 122, or the filter hole 121 is arranged on the bottom plate 122 and the side plate 123 at the same time. The arrangement of the filter hole 121 can isolate the solid medium in the filter space and filter the liquid medium to the outside of the filter space, and further realize the solid-liquid separation. Different arrangement positions of the filter hole 121 can meet the demand of different filtering efficiencies.
