DETAILED DESCRIPTION

[0032] 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 herein are intended to be illustrative rather than limiting.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] It should be noted that the drawings of this application use a base station as an example, which is only for the convenience of describing the technical solution of this application and is not intended to limit this application. It is understandable that the cleaning device of this application can be a base station or a cleaning robot.

[0037] See Figures 1 to 5 The present application provides a cleaning device 100, which includes a main body 10 and a cache container 20. The cache container 20 is arranged on the main body 10, and the cache container 20 includes an outer shell 21 and a filter element 22 arranged inside the outer shell 21. The filter element 22 includes a plurality of filter parts 221 for filtering liquid, and the plurality of filter parts 221 are arranged at intervals in the height direction of the cache container 20. Each filter part 221 forms a corresponding separation space inside the outer shell 21, and the plurality of separation spaces are connected in sequence. A liquid inlet 211 for liquid to enter is provided on the outer shell 21, and the liquid inlet 211 is connected to the separation space.

[0038] The number of filter parts 221 in the filter element 21 may refer to two or more than two, such as three, four, six, eight, etc.

[0039] For the cleaning device 100 of the present application, the liquid entering the cache container 20 through the liquid inlet 211 may be sewage. The sewage enters the separation space connected to it through the liquid inlet 211, and is filtered by the corresponding filter unit 221 in the separation space. After the sewage is filtered by the filter unit 221, dirt and impurities in the sewage can be removed, thereby avoiding the deposition of impurities in the sewage in the cleaning device 100, preventing the cleaning device 100 from stinking, and ensuring the user's experience. At the same time, in the cleaning device 100 of the present application, a plurality of filter units 221 are arranged at intervals in the height direction of the cache container 20, so that the sewage entering the outer shell 21 enters the plurality of separation spaces from top to bottom in turn, and is thereby filtered by the plurality of filter units 221 in turn, which not only avoids the situation where the filter unit 221 is blocked due to excessive impurities, but also improves the filtering effect of the sewage.

[0040] In this embodiment, the outer shell 21 of the cache container 20 includes a shell body 212 and a cover 213 disposed on the shell body 212. The shell body 212 is a box-shaped structure with an opening at the top, the cover 213 covers the opening of the shell body 212, and the filter element 22 is disposed inside the shell body 212.

[0041] The liquid inlet 211 of the buffer container 20 is provided on the cover 213 and communicates with the interior of the shell body 212. In this embodiment, the shell body 212 is also provided with a liquid outlet 214 for the outflow of filtered liquid. The liquid outlet 214 is provided on the shell body 212 and is disposed on a sidewall of the shell body 212.

[0042] The filter element 22 is arranged in the shell body 212, and the multiple filter parts 221 in the filter element 22 are arranged at intervals along the length direction of the cache container 20 so that the multiple separation spaces are arranged in a step-like manner.

[0043] In this embodiment, the filter element 22 includes three filter parts 221, which are spaced apart in the height direction of the buffer container 20. The filter element 22 also includes two baffles 222, which are respectively disposed between the three filter parts 221.

[0044] Specifically, the three filters 221 are a first filter 221a, a second filter 221b, and a third filter 221c. The two baffles 222 are a first baffle 222a and a second baffle 222b. The first filter 221a, the second filter 221b, and the third filter 221c are spaced apart from each other in the height direction of the buffer container 20 from top to bottom, and are arranged in sequence from one end of the buffer container 20 to the other in the length direction of the buffer container 20.

[0045] The filter section 221 has a first end and a second end, respectively. A first baffle 222a is disposed between the first filter section 221a and the second filter section 221b. The sidewalls of the first baffle 222a are connected to the second end of the first filter section 221a and the first end of the second filter section 221b, respectively. A second baffle 222b is disposed between the second filter section 221b and the third filter section 221c. The sidewalls of the second baffle 222b are connected to the second end of the second filter section 221b and the first end of the third filter section 221c, respectively. Each filter section 221 and its associated baffle 222 together enclose a separate space.

[0046] By connecting the filter parts 221 and the baffles 222 , the three filter parts 221 and the two baffles 222 can form a stepped structure in the height direction of the cache container 20 , so that the three separation spaces are arranged in a stepped manner in the height direction of the cache container 20 .

[0047] It can be understood that, in addition to the structural form of the filter element 22 shown above, which includes three filter parts 221 and two baffles 222, the number of filter parts 221 and baffles 222 in the filter element 22 can also be other settings, as long as it can ensure that the filter parts 221 and the baffles 222 are correspondingly enclosed to form a separated space.

[0048] In this embodiment, the filter portion 221 is a mesh structure, that is, the filter portion 221 is a filter mesh, and the filter portion 221 has a plurality of filter holes arranged at intervals. The mesh size and diameter of the filter holes can be set accordingly according to the amount of impurities in the sewage and the effect to be filtered.

[0049] The filter element 22 of this embodiment also includes a side panel 223, which is square in shape. The filter portion 221 and the baffle 222 are connected to the interior of the side panel 223, forming a box structure with an open top and a closed bottom. The first filter portion 221a, the second filter portion 221b, and the third filter portion 221c, as well as both ends of the first baffle 222a and the second baffle 222b, are connected to the inner walls of the side panel 223. The first end of the first filter portion 221a and the second end of the third filter portion 221c are respectively connected to the inner walls of the side panel 223.

[0050] In the height direction of the cache container 20 , the tops of the first baffle 222 a and the second baffle 222 b are both lower than the top of the side plate 223 , and the top of the second baffle 222 b is lower than the top of the first baffle 222 a .

[0051] The filter unit 221, baffle 222, and side panel 223 enclose a box structure, and the bottom of the box structure is sealed by the connection between the filter unit 221 and baffle 222. The filter element 22 is disposed within the housing 212, with a gap between the bottom of the box structure and the bottom wall of the housing 212.

[0052] In this embodiment, the filter element 22 further includes a flange 224 disposed around the periphery of the opening of the box structure. The bottom of the flange 224 abuts against the periphery of the opening of the shell body 212, thereby creating a gap between the bottom of the box structure and the bottom wall of the shell body 212 and allowing the filter element 22 to be removably disposed within the shell body 212.

[0053] By setting the filter element 22 and the shell body 212 in a detachable connection, the filter element 22 can be easily replaced in the buffer container 20. When the filter portion 221 in the filter element 22 needs to be replaced, the cover 213 can be opened to remove the filter element 22, and then a new filter element 22 can be installed in the shell body 212.

[0054] In this embodiment, the liquid inlet 211 is positioned to correspond to the compartment formed by the first filter section 221a and the first baffle 222a. When sewage enters the buffer container 20 through the liquid inlet 211, it first flows into the compartment formed by the first filter section 221a. The sewage filtered by the first filter section 221a is deposited at the bottom of the shell body 212. Simultaneously, the sewage overflows from the compartment formed by the first filter section 221a and then enters the compartment formed by the second filter section 221b and the compartment formed by the third filter section 221c, respectively. The sewage is filtered by the second and third filter sections 221b and 221c, and the filtered sewage is deposited at the bottom of the shell body 212.

[0055] Through the stepped arrangement of the various separated spaces in the filter element 22, multiple filter parts 221 can filter the sewage in turn, which can avoid the situation where the filter element 22 cannot filter after some filter parts 221 are blocked. While ensuring that the filter element 22 effectively filters the sewage, it can also improve the filtering effect of the sewage.

[0056] In addition, in other examples of this embodiment, the lengths of the multiple filter parts 221 can be set to gradually increase from top to bottom in the height direction of the buffer container 20. Specifically, the circumference of the lower filter part 221 can be set to extend outwardly beyond the circumference of the upper filter part 221, so that the multiple filter parts 221 are arranged in a pyramid shape; or the lower filter part 221 can be set to partially extend outwardly beyond the upper filter part 221, so that the multiple filter parts 221 are arranged in an inclined ladder shape.

[0057] The above configurations can enable the multiple filter parts 221 to filter the sewage in sequence, ensuring that the filter element 22 can effectively filter the sewage while also improving the sewage filtering effect.

[0058] In this embodiment, the bottom surface of the shell body 212 is inclined. The liquid outlet 214 is located near the bottom of the shell body 212 at a lower point in the height direction of the buffer container 20. This arrangement allows the filtered wastewater to be better collected at the lower part of the shell body 212 and to flow out smoothly from the liquid outlet 214.

[0059] Furthermore, the main body 10 of the cleaning device 100 includes a base 11 and a housing 12 disposed on the base 11. The housing 12 includes a housing frame 121, a rear shell 122 disposed at the rear side of the housing frame 121, a front shell 123 disposed at the front side of the housing frame 121, and a display panel 124 connected to the top of the front shell 123. The rear shell 122, the front shell 123, and the display panel 124 together form a box structure.

[0060] The housing 12 of this embodiment further includes a top cover 125 , which is disposed on the top of the box frame 121 to cover the box structure, thereby sealing the interior of the box structure.

[0061] In this embodiment, the cleaning device 100 further includes a dirty liquid collection tank 30, which is disposed on the base 11. The dirty liquid collection tank 30 has a cleaning chamber 31 formed therein. The dirty liquid collection tank 30 has a first inlet and a first outlet, both of which are connected to the cleaning chamber 31.

[0062] One side of the dirty liquid collection box 30 is provided with an opening connected to the cleaning chamber 31. The cleaning robot can enter the cleaning chamber 31 through the opening of the dirty liquid collection box 30, and the mopping and wiping parts of the cleaning robot can be cleaned by clean water in the cleaning chamber 31. When the mopping and wiping parts are cleaned, dirty water will be generated in the dirty liquid collection box 30.

[0063] The first outlet of the waste liquid collection box 30 is connected to the liquid inlet 211 of the buffer container 20 via a first pipe, allowing waste water to enter the buffer container 20. Under the action of the filter element 22, impurities such as garbage and particulate matter in the waste water are filtered out. The waste water with impurities removed is deposited at the bottom of the shell body 212 and flows out through the liquid outlet 214.

[0064] The cleaning device 100 further includes a first driving member 41, which is disposed on the first pipeline to drive the sewage from the sewage collection tank 30 into the buffer container 20. The first driving member 41 may be an air pump.

[0065] Combine Figure 6 and Figure 7 In this embodiment, the cleaning device 100 further includes a clean water tank 50, which is disposed within the housing structure of the casing 12 and above the waste liquid collection tank 30. A gap is provided between the periphery of the clean water tank 50 and the rear housing 122. The clean water tank 50 is used to store clean water. The clean water tank 50 has a second inlet and a second outlet.

[0066] The clean water tank 50 includes a main body 51 and an upper cover 52 disposed on the main body 51. The main body 51 is a box-shaped structure with an opening at the top. The upper cover 52 is disposed within the opening. A sealing ring 53 is provided around the periphery of the opening of the main body 51 to ensure a tight seal between the main body 51 and the upper cover 52. The upper cover 52 is provided with a handle 54 to facilitate removal of the clean water tank 50 from the housing 12. A water inlet 521 is provided on the upper cover 52 for manually adding clean water to the clean water tank 50. The water inlet 521 is sealed by a water inlet cap 522.

[0067] In this embodiment, combined with Figures 8 to 10 The cleaning device 100 further includes a filter 60 and a storage container 70 , and the filter 60 and the storage container 70 are connected between the dirty liquid collection tank 30 and the clean water tank 50 .

[0068] The filter 60 is disposed between the clean water tank 50 and the rear housing 122. A filter chamber is defined within the filter 60. A filter inlet 61 and a filter outlet 62 are defined within the filter 60, both communicating with the filter chamber. The filter 60 also includes a filter membrane disposed within the filter chamber for filtering liquid.

[0069] The filter membrane is a membrane-like structure made of filter material that filters liquids. Multiple filter membranes can be provided, spaced apart in a direction extending from the filter inlet 61 to the filter outlet 62, to filter the liquid layer by layer, enhancing the filtration effect. The filter membrane of filter 60 can filter sewage to remove impurities such as suspended matter, particulate matter, and colored matter, thereby filtering the sewage into clear water.

[0070] The storage container 70 is disposed between the clean water tank 50 and the rear housing 122. A liquid storage cavity is provided inside the storage container 70. A third inlet 701 and a third outlet 702 are provided on the storage container 70. Both the third inlet 701 and the third outlet 702 are communicated with the liquid storage cavity.

[0071] The storage container 70 of this embodiment also includes a storage shell 71 and an oxidation module 72. The storage shell 71 is a box-shaped structure, and the internal space of the storage shell 71 constitutes a liquid storage cavity. The third inlet 701 is provided at the top of the storage shell 71 body 12, and the third outlet 702 is provided on the side wall of the storage shell 71. The oxidation module 72 is arranged in the liquid storage cavity, and the oxidation module 72 includes a pair of electrodes 721. When the oxidation module 72 is energized, the electrodes 721 electrolyze the liquid into a solution containing ozone through low-voltage electrolysis. Based on the oxidizing property of ozone, ozone can cause chemical reactions with bacteria, suspended matter, organic matter, and microorganisms in the liquid, causing them to be destroyed or decomposed, thereby achieving the effects of preventing odor, disinfecting and sterilizing, and reducing water pollution indicators.

[0072] In this embodiment, the liquid outlet 214 of the cache container 20 is connected to the filter inlet 61 of the filter unit through the second pipeline, the filter outlet 62 of the filter unit is connected to the third inlet 701 of the storage container 70 through the third pipeline, the third outlet 702 of the storage container 70 is connected to the second inlet of the clean water tank 50 through the fourth pipeline, and the second outlet of the clean water tank 50 is connected to the first inlet of the dirty liquid collection tank 30 through the fifth pipeline.

[0073] The mopping and wiping parts of the cleaning robot are cleaned in the dirty liquid collection tank 30, and sewage is generated in the dirty liquid collection tank 30. The sewage enters the buffer container 20 from the dirty liquid collection tank 30. The filter element 22 in the buffer container 20 can first filter out large garbage or large particles of impurities in the sewage. The sewage that has completed the preliminary filtration enters the filter 60 from the liquid outlet 214 of the buffer container 20. Under the action of the filter membrane of the filter 60, the sewage that has completed the preliminary filtration is filtered again, and small particles, suspended matter, colored substances and other impurities in the sewage are removed, and the sewage is filtered into clean water. The clean water that has completed filtration in the filter 60 enters the storage container 70, and under the action of the oxidation module 72, the clean water is sterilized, disinfected and deodorized. The clean water that has completed disinfection and deodorization enters the dirty liquid collection tank 30 from the clean water tank 50 and is used to clean the mopping and wiping parts, thereby realizing the recycling of sewage.

[0074] By filtering and sterilizing the sewage and converting it into clean water for recycling, the duration of the cleaning device 100's operation can be increased, the frequent manual operation of adding clean water to the clean water tank 50 can be avoided, and water can be saved. At the same time, by using ozone for sterilization, disinfection and deodorization, the problem of the clean water tank 50 being prone to stinking can be solved. In addition, recycling the sewage in the dirty liquid collection tank 30 can avoid the operation of manually dumping sewage, making the cleaning device 100 more intelligent. On this basis, the volume of the clean water tank 50 can be increased and the storage capacity of clean water can be increased to make the cleaning device 100 work more sustainably and enhance the user experience. In addition, by providing a buffer container 20, the sewage in the dirty liquid collection tank 30 can be cached in time to avoid the long-term storage of sewage in the dirty liquid collection tank 30. Combined with the provision of the storage container 70, a small amount of sewage can be quickly and promptly processed and clean water can be cached, thereby enhancing the flexibility of the use of the cleaning device 100.

[0075] In this embodiment, a second driving member 42 is provided on the third pipeline, which is used to drive the clean water filtered by the filter 60 into the storage container 70. A third driving member 43 is provided on the fourth pipeline, which is used to drive the clean water in the storage container 70 that has been disinfected and deodorized to enter the clean water tank 50. The second driving member 42 can be a peristaltic pump or a water pump, and the third driving member 43 can be a peristaltic pump or an air pump.

[0076] In addition, the cleaning device 100 of this embodiment further includes a water supply pump 44, which is provided on the fifth pipeline and is used to pump clean water in the clean water tank 50 into the dirty liquid collection tank 30 to clean the mopping parts and realize the recycling of sewage.

[0077] In this embodiment, combined with Figure 1 and Figure 11 The cleaning device 100 further includes a charging assembly 80. The charging assembly 80 is disposed on the base 11 and is used to charge the cleaning robot. The cleaning device 100 further includes a maintenance cover 90, which is disposed on the housing 12 and corresponds to the filter 60. The maintenance cover 90 is detachably disposed on the housing 12 to facilitate later replacement of the filter membrane in the filter 60.

[0078] When the cleaning device 100 of this embodiment is in use, the mopping and wiping parts of the cleaning robot are cleaned in the cleaning chamber 31 of the dirty liquid collection tank 30. The sewage generated in the dirty liquid collection tank 30 enters the buffer container 20, and the filter element 22 in the buffer container 20 performs preliminary filtration on the sewage to remove large particles of impurities. The initially filtered sewage enters the filter 60 and is filtered into clean water by the filter membrane. The filtered clean water enters the storage container 70. Under the action of the oxidation module 72, the clean water is electrolyzed to produce ozone to sterilize, disinfect and deodorize the clean water. The clean water that has completed disinfection enters the clean water tank 50, and then enters the dirty liquid collection tank 30 from the clean water tank 50 to be used for cleaning the mopping and wiping parts, thereby completing recycling.

[0079] During the cleaning operation, the above steps are repeated until the cleaning is completed and the cleaning device 100 stops working.

[0080] For the cleaning device of this embodiment, a cache container is provided on the main body, and the cache container includes a filter element, and the filter element includes a plurality of filter parts for filtering liquids. The plurality of filter parts are spaced apart in the height direction of the cache container, and each filter part forms a corresponding separation space. The liquid entering the cache container from the liquid inlet may be sewage, and the sewage enters the separation space connected thereto from the liquid inlet, and is filtered by the corresponding filter part in the separation space. After the sewage is filtered by the filter part, dirt and impurities in the sewage can be removed, thereby avoiding the deposition of impurities in the sewage in the cleaning device, preventing the cleaning device from stinking, and ensuring the user experience. At the same time, in the cleaning device of the present application, the plurality of filter parts are spaced apart in the height direction of the cache container, so that the sewage entering the outer shell enters the plurality of separation spaces from top to bottom in turn, thereby being filtered by the plurality of filter parts in turn, which not only avoids the situation where the filter part is blocked due to excessive impurities, but also improves the filtering effect of the sewage.
