Description

Technical Field

[0001] The utility model relates to the technical field of cleaning, in particular to a cleaning component and a cleaning device. Background Art

[0002] As people's requirements for quality of life continue to increase, more and more families choose to equip their homes with cleaning equipment such as sweeping robots, floor washing robots, and mopping robots. These cleaning equipment can automatically perform heavy and dirty cleaning tasks on behalf of users, freeing users' hands.

[0003] In the related art, mopping robots use mops to clean the floor. Since the mops will retain dirty water after mopping the floor, some mopping robots are also equipped with a wiper structure, which can squeeze out the dirty water in the mops. However, when the traditional wiper squeezes and wipes the mops, it is inevitable that a small amount of dirty water will overflow from the end of the wiper that contacts the mops and drip onto the floor, causing pollution to the floor and affecting the cleaning effect.

[0043] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0044] In the description of the present invention, it should be understood that the descriptions involving orientation, such as the orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0045] In the description of the present utility model, "a plurality" means more than two. If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0046] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0047] The present application provides a cleaning component and a cleaning device using the cleaning component.

[0048] Specifically, the cleaning equipment provided in the present application may include but is not limited to mopping robots, sweeping and mopping robots, floor washing robots, and the like that can mop the surface to be cleaned (such as the floor). The cleaning equipment will be described in detail below using the mopping robot as an example.

[0049] Please refer to Figure 1 , Figure 1The cleaning device 10 comprises a housing 100, a cleaning assembly 200 and an electric control module (not shown in the figure).

[0050] The housing 100 is used to form the main body outline of the cleaning device 10, and is used as a mounting carrier to position, support and connect components such as the cleaning assembly 200 and the electric control module.

[0051] As the main power supply and control component of the cleaning device 10, the electric control module can provide power to the cleaning device 10 and control the cleaning device 10 to perform various functional operations. For example, the electric control module can be electrically connected to the cleaning component 200 to control the movement of the cleaning component 200 to clean the surface 20 to be cleaned.

[0052] The cleaning assembly 200 is a core component of the cleaning device 10 for completing the cleaning operation. The cleaning assembly 200 includes a cleaning mechanism 210. When the cleaning device 10 is a mopping robot, the cleaning mechanism 210 may be a mopping mechanism, and the cleaning device 10 can use the mopping mechanism to mop the surface 20 to be cleaned. It can be understood that the cleaning mechanism 210 can clean a wet surface 20 to be cleaned, or a dry surface 20 to be cleaned.

[0053] For example, the cleaning component 200 may also include a clean water box (not shown in the figure), which is used to store clean water. During the cleaning process of the dry surface 20 to be cleaned, the cleaning device 10 can guide the clean water in the clean water box to the cleaning mechanism 210, and soak the cleaning mechanism 210 with the clean water, so that the soaked cleaning mechanism 210 mops and cleans the surface 20 to be cleaned.

[0054] Please continue to refer to Figure 1 The cleaning mechanism 210 includes a rotating portion 211 and a cleaning member 212 sleeved on the circumferential surface of the rotating portion 211. The rotating portion 211 can drive the cleaning member 212 to rotate to achieve mopping and cleaning of the surface to be cleaned 20. By setting the rotating portion 211 to drive the cleaning member 212 to rotate, the friction between the cleaning member 212 and the surface to be cleaned 20 can be enhanced, making it easier to wipe off the stains on the surface to be cleaned 20.

[0055] The cleaning member 212 may be a mop, and the cleaning member 212 may include a cleaning layer (not shown) and a connecting layer (not shown) stacked along its thickness direction, and the connecting layer is sleeved on the circumferential surface of the rotating portion 211, and the connecting layer and the circumferential surface of the rotating portion 211 have a large friction force, so that the rotating portion 211 can better drive the cleaning member 212 to rotate as a whole, and avoid the cleaning member 212 from slipping. For example, the connecting layer may be made of rubber material.

[0056] The cleaning layer is connected to the side of the connecting layer away from the rotating part 211, and the cleaning layer needs to have good water absorption and flexible deformation ability. It can be understood that the cleaning layer can be made of a flexible material that easily retains water, for example, the cleaning layer can be flannel, sponge, etc.

[0057] The rotating part 211 can be a roller. It can be understood that the number of rotating parts 211 can be one or more. When the number of rotating parts 211 is one, the cleaning member 212 is mounted around the entire circumference of the rotating part 211, and the cross-section of the cleaning member 212 is circular. When the number of rotating parts 211 is multiple, the multiple rotating parts 211 are arranged in the same plane, and the cleaning member 212 can be mounted on a partial circumference of each rotating part 211. At this time, the cross-section of the cleaning member 212 is runway-shaped (or track-shaped). In one embodiment of the present application, refer to Figure 1 As shown, the cleaning mechanism 210 is provided with two rotating parts 211, and the cleaning member 212 is sleeved on the two rotating parts 211. It should be understood that the drawings of the embodiment of the present application are only for illustration of the example that two rotating parts 211 are provided, and cannot be regarded as a limitation of the present application.

[0058] The cleaning member 212 includes a first cleaning segment 2121 connected to the circumferential surface of the rotating portion 211. It can be understood that the first cleaning segment 2121 refers to the portion of the cleaning member 212 that fits the circumferential surface of the rotating portion 211. For example, when there is only one rotating portion 211, the cleaning member 212 can surround and fit the entire circumferential surface of the rotating portion 211, and the cleaning member 212 as a whole serves as the first cleaning segment 2121. When there are multiple rotating portions 211, the cleaning member 212 surrounds part of the circumferential surfaces of multiple rotating portions 211, and the cleaning member 212 can form multiple first cleaning segments 2121 spaced apart from each other. Figure 1 For example, when there are two rotating parts 211, the cleaning member 212 only surrounds and fits on the two circumferential surfaces of the two rotating parts 211 that are opposite to each other. Then, the cleaning member 212 fits on the two circumferential surfaces of the two rotating parts 211 that are opposite to each other to form two first cleaning segments 2121, each of which is a semicircular arc segment. Moreover, two second cleaning segments 2122 are connected between the two first cleaning segments 2121, and each of which is a flat segment extending in a belt shape.

[0059] It should be noted that the first cleaning segment 2121 refers to the portion where the cleaning member 212 is connected (fitted) to the circumferential surface of the rotating portion 211. When there are multiple rotating portions 211, the first cleaning segment 2121 will change as the rotating portion 211 rotates. Any portion of the cleaning member 212 can become the first cleaning segment 2121 when it moves to contact the circumferential surface of the rotating portion 211.

[0060] In some optional embodiments, the cleaning component 200 may also include a cleaning brush (or a sweeping roller brush) and a dust box. The cleaning device 10 can gather dust, debris and other dirt on the surface 20 to be cleaned by using the cleaning brush, and suck the dirt into the dust box through negative pressure.

[0061] During the process of the cleaning member 212 mopping and cleaning the surface 20 to be cleaned, the stains wiped off the surface 20 to be cleaned will be absorbed by the water, so that dirty water will remain in the cleaning member 212. In order to prevent the cleaning member 212 from squeezing the dirty water onto the surface 20 to be cleaned when contacting and rubbing with the surface 20, please combine Figure 1 And refer to Figure 2 , Figure 2 for Figure 1 The cleaning assembly 200 further includes a wiper 220 to timely scrape out the sewage stored in the cleaning member 212 through the wiper 220 .

[0062] The wiper plate 220 is disposed outside the cleaning mechanism 210 . A wiper portion 221 is disposed at one end of the wiper plate 220 . The wiper portion 221 abuts against the first cleaning section 2121 .

[0063] It can be understood that the wiper portion 221 and the first cleaning section 2121 of the cleaning member 212 are in an interference fit. When the rotating portion 211 drives the cleaning member 212 to rotate, the wiper portion 221 and the first cleaning section 2121 are squeezed to scrape out the sewage in the first cleaning section 2121. As the rotating portion 211 continues to rotate, the wiper portion 221 can scrape out the sewage in the entire cleaning member 212.

[0064] In order to prevent the sewage scraped out by the wiper portion 221 from being reabsorbed by the cleaning member 212, a water guide surface may be formed on the wiper plate 220, and the wiper plate 220 may guide the scraped sewage to flow away in time through the water guide surface, so that the wiper plate 220 not only has the function of scraping the sewage, but also has the function of draining the sewage. For example, the cleaning component 200 may also include a sewage box, and the water guide surface may guide the scraped sewage to flow into the sewage box. Alternatively, a sewage collection tank may be provided at one end of the wiper plate 220 away from the cleaning member 212, and the water guide surface may guide the scraped sewage to flow into the sewage collection tank first, and then the sewage is pumped away by a water pump.

[0065] Please combine Figure 2 And refer to Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the sewage flow path when the cleaning element of the embodiment of the utility model rotates clockwise. Figure 4The schematic diagram of the sewage flow path when the cleaning member of the embodiment of the utility model rotates counterclockwise is shown. The wiper 220 includes a first water diversion surface 222 and a second water diversion surface 223. The first water diversion surface 222 is arranged on the side of the wiper 220 away from the surface to be cleaned 20, and the second water diversion surface 223 is arranged on the side of the wiper 220 facing the surface to be cleaned 20, so that the sewage scraped by the wiper 221 flows along the first water diversion surface 222 or the second water diversion surface 223.

[0066] Among them, the first water guide surface 222 is arranged on the side of the wiper 220 away from the surface 20 to be cleaned, that is, the first water guide surface 222 is the upper surface of the wiper 220, and the second water guide surface 223 is arranged on the side of the wiper 220 facing the surface 20 to be cleaned, that is, the second water guide surface 223 is the lower surface of the wiper 220. In other words, the first water guide surface 222 and the second water guide surface 223 are respectively arranged on the two sides of the wiper 220 that are away from each other. Then, taking the wiper 220 being arranged at the front end of the cleaning mechanism 210 as an example, when the rotating part 211 rotates clockwise, as Figure 3 As shown in FIG. 2 , at this time, the first water diversion surface 222 is a "water-facing surface", and the sewage squeezed out by the scraper 221 can flow away along the first water diversion surface 222. When the rotating part 211 rotates counterclockwise, as shown in FIG. Figure 4 As shown, at this time, the second water diversion surface 223 is a “water-facing surface”, and the sewage squeezed out by the scraper 221 can flow away along the second water diversion surface 223 .

[0067] Then, by respectively providing two water diversion surfaces on opposite sides of the wiper 220, there is no need to limit the rotation direction of the rotating part 211. Regardless of whether the rotating part 211 rotates clockwise or counterclockwise, the wiper 220 can always drain the sewage squeezed out by the wiper 221 through one of the water diversion surfaces. This arrangement makes the working mode design of the cleaning device 10 more flexible, can provide more working modes, and can meet more cleaning needs.

[0068] For example, the rotating part 211 drives the cleaning member 212 to rotate in a clockwise direction, so that when the cleaning device 10 moves forward, the sewage squeezed out by the wiper 220 can flow away through the first water diversion surface 222; when the rotating part 211 drives the cleaning member 212 to rotate in a counterclockwise direction, so that when the cleaning device 10 moves backward, the sewage squeezed out by the wiper 220 can flow away through the second water diversion surface 223, so that the cleaning device 10 can wipe water when moving forward or backward.

[0069] However, when the rotating part 211 rotates in a clockwise direction, the wiper 220 discharges the sewage squeezed out by the wiper part through the first water diversion surface 222. Since the cleaning member 212 is usually made of flexible material, when the wiper part 221 is squeezed by the cleaning member 212, it is inevitable that a small amount of sewage will leak out or overflow from the contact portion between the wiper part 221 and the cleaning member 212, and the sewage leaked from the wiper part 221 is easy to drip onto the surface 20 to be cleaned; when the rotating part 211 rotates in a counterclockwise direction, the wiper 220 can discharge the sewage squeezed out by the wiper part through the second water diversion surface 223. However, since the second water diversion surface 223 is the side of the wiper 220 facing the surface 20 to be cleaned, when there is a lot of sewage, the sewage flowing along the second water diversion surface 223 is easy to drip directly onto the surface 20 to be cleaned under the action of gravity, causing pollution to the surface 20 to be cleaned, affecting the cleaning effect of the cleaning device 10.

[0070] In this regard, in order to prevent the dirty water scraped by the wiper 220 from dripping onto the surface to be cleaned 20, in an embodiment of the present application, the cleaning component 200 also includes a water receiving plate 230, which is arranged between the wiper 220 and the surface to be cleaned 20, and the water receiving plate 230 is used to receive the dirty water leaked from the wiper part 221.

[0071] By arranging a water receiving plate 230 between the wiper 220 and the surface 20 to be cleaned, in other words, the water receiving plate 230 is arranged on the side of the wiper 220 facing the surface 20 to be cleaned, that is, the water receiving plate 230 is arranged on the lower side of the wiper 220, then, in the process of the wiper 220 wiping the cleaning member 212, whether there is sewage directly leaking from the end of the wiper portion 221 or there is sewage dripping from the second water guide surface 223, the water receiving plate 230 can receive the dripping sewage, thereby preventing the sewage from dripping onto the surface 20 to be cleaned, avoiding affecting the cleaning effect of the cleaning component 200, and improving the user experience.

[0072] One end of the water receiving plate 230 is adjacent to the first cleaning section 2121 and is spaced apart from the surface of the first cleaning section 2121 .

[0073] It is understandable that the end of the water receiving plate 230 is arranged close to the first cleaning section 2121, so that the water receiving plate 230 is located as far as possible within the range where the sewage falls, so as to ensure that the water receiving plate 230 can receive all the sewage dripping from the lower side of the wiper plate 220. At the same time, one end of the water receiving plate 230 is spaced from the surface of the first cleaning section 2121, that is, there is a clearance fit between the water receiving plate 230 and the cleaning member 212, so that the end of the water receiving plate 230 close to the cleaning member 212 will not contact the cleaning member 212, and the water receiving plate 230 will not have a scraping effect on the cleaning member 212, and will not scrape out the remaining sewage in the cleaning member 212, thereby preventing the water receiving plate 230 from scraping and squeezing the remaining sewage in the cleaning member 212 and dripping it onto the surface 20 to be cleaned.

[0074] The distance between one end of the water receiving plate 230 close to the first cleaning section 2121 and the surface of the first cleaning section 2121 may be 0-5 mm.

[0075] In one embodiment, the wiper plate 220 extends axially along the rotating portion 211 , and the length of the wiper plate 220 along the axial direction of the rotating portion 211 is greater than or equal to the length of the cleaning member 212 along the axial direction of the rotating portion 211 .

[0076] By setting the length of the wiper plate 220 to be greater than or equal to the axial length of the cleaning member 212, the wiper plate 220 is made into a long strip. Then, during the rotation of the cleaning member 212, the wiper plate 220 can gradually abut against any part of the cleaning member 212, so that the wiper plate 220 can scrape and squeeze out the sewage from various parts of the cleaning member 212, thereby enhancing the sewage removal effect of the cleaning member 212, avoiding the cleaning member 212 from retaining a large amount of sewage after scraping, and preventing the cleaning member 212 from leaving stains on the surface 20 to be cleaned during the wiping process.

[0077] In one embodiment, the water receiving plate 230 extends axially along the rotating portion 211 , and the length of the water receiving plate 230 along the axial direction of the rotating portion 211 is greater than or equal to the length of the wiper plate 220 along the axial direction of the rotating portion 211 .

[0078] By setting the length of the water receiving plate 230 to be greater than or equal to the length of the wiper plate 220 , sewage leaking from any axial position of the wiper plate 220 can drip onto the water receiving plate 230 , thereby ensuring that the sewage does not drip onto the surface 20 to be cleaned.

[0079] In one embodiment, the distance between the wiper 220 and the surface 20 to be cleaned decreases from an end of the wiper 220 close to the first cleaning section 2121 to an end of the wiper 220 far from the first cleaning section 2121 .

[0080] Through the above arrangement, the wiper blade 220 is not parallel to the surface to be cleaned 20, so that the first water guide surface 222 and the second water guide surface 223 can be designed as inclined surfaces.

[0081] The distance between the wiper blade 220 and the surface 20 to be cleaned decreases from the end of the wiper blade 220 close to the first cleaning section 2121 to the end away from the first cleaning section 2121. The end of the wiper blade 220 close to the first cleaning section 2121 is at a high position, and the end away from the first cleaning section 2121 is at a low position, so that the sewage scraped on the wiper blade 220 has the power to flow downward under the action of gravity. The wiper blade 220 can guide the sewage to flow away quickly, avoiding excessive sewage from staying in the contact area between the wiper blade 220 and the cleaning member 212. In this way, the sewage leaking from the lower side of the wiper portion 221 can be reduced, and the problem of sewage leaking from the lower side of the wiper portion 221 can be improved from the source; at the same time, it is avoided that too much sewage stays in the contact area between the wiper blade 220 and the cleaning member 212, causing part of the sewage to be reabsorbed by the cleaning member 212.

[0082] In one embodiment, the distance between the water receiving plate 230 and the surface to be cleaned 20 decreases from an end of the water receiving plate 230 close to the first cleaning section 2121 to an end of the water receiving plate 230 far from the first cleaning section 2121 .

[0083] Through the above arrangement, the end of the water receiving plate 230 close to the first cleaning section 2121 is at a higher position, and the end away from the first cleaning section 2121 is at a lower position. Therefore, the sewage dripping onto the water receiving plate 230 will be more likely to flow downward along the surface of the water receiving plate 230 under the action of gravity, that is, flow in the direction away from the first cleaning section 2121, and will not flow toward the first cleaning section 2121 (that is, flow upward) to cause the sewage to leak from the end of the water receiving plate 230 close to the first cleaning section 2121 and drip onto the surface 20 to be cleaned.

[0084] It can be understood that in order to treat the sewage dripping onto the water receiving plate 230, a sewage collection structure can be set on one side of the water receiving plate 230. For example, a sewage collection tank can be set at one end of the water receiving plate 230 away from the first cleaning section 2121, so that the sewage received by the water receiving plate 230 flows into the sewage collection tank.

[0085] In one embodiment, the cleaning assembly 200 further includes a sewage box 240 , which is disposed on one side of the cleaning mechanism 210 , and one end of the water receiving plate 230 away from the first cleaning section 2121 is connected to the sewage box 240 so that the sewage received by the water receiving plate 230 flows into the sewage box 240 .

[0086] The water receiving plate 230 may be a separate connection structure with the sewage box 240 , or may be integrally provided with the sewage box 240 .

[0087] In one embodiment, the water receiving plate 230 and the sewage box 240 are integrally formed. Figure 2 As shown, the water receiving plate 230 may be a structure formed by extending the wall of the sewage box 240 close to the first cleaning section 2121 outward.

[0088] Specifically, the water receiving plate 230 and the sewage box 240 can be integrally injection molded using an injection molding process, so that the water receiving plate 230 and the sewage box 240 are formed into an integral connection structure. The two are a whole, and the connection and assembly steps between the two can be omitted, which facilitates the overall assembly of the cleaning device 10; moreover, because the water receiving plate 230 and the sewage box 240 are integrally formed, there is no assembly gap between the water receiving plate 230 and the sewage box 240, and there will be no situation where sewage leaks from the assembly gap between the water receiving plate 230 and the sewage box 240, and there is no need to consider the assembly sealing design of the two.

[0089] In one embodiment, the wiper plate 220 includes a water outlet end 224 away from the first cleaning section 2121 , and the orthographic projection of the water outlet end 224 on the surface to be cleaned 20 is located within the orthographic projection range of the water receiving plate 230 on the surface to be cleaned 20 .

[0090] The orthographic projection of the water outlet end 224 on the surface to be cleaned 20 is located within the orthographic projection range of the water receiving plate 230 on the surface to be cleaned 20, that is, the lowest end of the wiper plate 220 is located directly above the water receiving plate 230, then, the sewage scraped out by the wiper portion 221 can flow along the first water guide surface 222 of the wiper plate 220, and directly flow out from the water outlet end 224 and fall onto the water receiving plate 230, and flow along the water receiving plate 230 to the sewage collection structure, such as the sewage box 240.

[0091] To facilitate the overall assembly of the cleaning assembly 200 , the wiper plate 220 may also be connected to the sewage box 240 .

[0092] In one embodiment, please refer to Figure 2 The sewage box 240 includes a first wall 241 facing the first cleaning section 2121. The first wall 241 is located on the side of the wiper 220 away from the water receiving plate 230, and the first wall 241 is connected to the end of the wiper 220 away from the first cleaning section 2121. A water outlet 242 is provided at the connection between the first wall 241 and the wiper 220, so that the sewage scraped by the wiper 220 flows into the sewage box 240 through the water outlet 242.

[0093] The wiper plate 220 can be integrally formed with the sewage box 240. Specifically, the wiper plate 220 and the sewage box 240 can be integrally formed by injection molding.

[0094] Then, by forming the wiper plate 220 and the sewage box 240 as one piece, the wiper plate 220 and the sewage box 240 are an integrated connection structure, and the two are a whole, so that the connection step between the two can be omitted, and the overall assembly of the cleaning device 10 is convenient; and since the two do not need to be connected, there will be no assembly error caused by the connection between the two, and it is easier to ensure that the wiper plate 220 is in the position required by the design after assembly, so that the wiper plate 220 can scrape out the sewage in the cleaning member 212. In addition, since the wiper plate 220 and the sewage box 240 are an integrated structure, there is no assembly gap between the wiper plate 220 and the sewage box 240, and there is no need to consider the assembly sealing design of the two, and there will be no problem of sewage leaking from the assembly gap between the wiper plate 220 and the sewage box 240.

[0095] When the cleaning member 212 is wiping the surface 20 to be cleaned, the wiper 220 can scrape out most of the sewage in the cleaning member 212, and scrape off some of the dirt adhering to the cleaning member 212 and enter the sewage box 240 along with the sewage. However, it is difficult for the wiper 220 to scrape off all the sewage during the cleaning process, and some dirt will still remain on the cleaning member 212. If the remaining sewage and dirt are not processed, the next cleaning operation will be affected, affecting the cleaning effect.

[0096] To improve the above situation, the rotation direction of the rotating part 211 can be adjusted to change the rotation direction of the cleaning member 212, so that the cleaning member 212 is subjected to scraping forces in different directions, making it easier to scrape off the remaining sewage and dirt on the cleaning member 212. For example, in one embodiment, when the cleaning device 10 is in a cleaning operation, the rotating part 211 can be controlled to continuously rotate forward, so that the wiper 220 can scrape off most of the sewage and dirt on the cleaning member 212, and continuous forward rotation can ensure the consistency of the cleaning effect; after the cleaning operation is completed, the rotating part 211 can be controlled to reverse, so that the wiper 220 can scrape off the remaining sewage and dirt on the cleaning member 212.

[0097] The cleaning assembly 200 may also include a driving mechanism (not shown) connected to the rotating portion 211, and the driving mechanism is used to drive the rotating portion 211 to rotate to drive the cleaning member 212 to rotate. The rotation direction of the rotating portion 211 can be changed by controlling the driving mechanism, thereby adjusting the rotation direction of the cleaning member 212.

[0098] In one embodiment, the driving mechanism includes a first driving mode and a second driving mode. In the first driving mode, the driving mechanism is used to drive the rotating part 211 to rotate around a first direction so that the sewage scraped by the wiper part 221 flows along the first water diversion surface 222, and the first direction is one of a clockwise direction and a counterclockwise direction. In the second driving mode, the driving mechanism is used to drive the rotating part 211 to rotate around a second direction so that the sewage scraped by the wiper part 221 flows along the second water diversion surface 223, and the second direction is opposite to the first direction.

[0099] by Figure 1 Taking the example of setting the wiper 220 at the front end of the cleaning mechanism 210, in the first driving mode, the first direction needs to be set to the clockwise direction, and the driving mechanism drives the rotating part 211 to rotate in the clockwise direction, driving the cleaning member 212 to rotate in the clockwise direction. At this time, the first water diversion surface 222 is the "water-facing surface", so that the sewage scraped by the wiper 221 can flow along the first water diversion surface 222, and the wiper 220 scrapes off some dirt and flows with the sewage. In the second driving mode, the second direction is the counterclockwise direction, and the driving mechanism drives the rotating part 211 to rotate in the counterclockwise direction, which can drive the cleaning member 212 to rotate in the counterclockwise direction, so that the wiper 220 can scrape out the remaining sewage in the cleaning member 212, and the scraped and squeezed sewage flows along the second water diversion surface 223, and the wiper 220 can also scrape off the remaining dirt and flow with the sewage.

[0100] Then, by setting two driving modes, the dirty water and dirt on the cleaning member 212 can be scraped clean by driving the rotating part 211 to rotate forward and reverse respectively. It is easy to understand that in order to make the cleaning device 10 perform a better cleaning operation, the first driving mode can be used as the main cleaning mode of the cleaning device 10, and the second driving mode can be used as the self-cleaning mode of the cleaning device 10. During the cleaning operation, the cleaning device 10 controls the driving mechanism to execute the first driving mode. After the cleaning operation is completed, the cleaning device 10 can return to the base station and control the driving mechanism to execute the second driving mode.

[0101] In one embodiment, if Figure 1 As shown, the wiper plate 220 is located on the side of the horizontal plane where the axis of the rotating part 211 is located, away from the surface 20 to be cleaned. That is to say, the wiper plate 220 is arranged above the axis of the rotating part 211, and the wiper part 221 abuts against the upper surface of the circumferential surface of the first cleaning section 2121. Then, a part of the sewage leaked from the lower side of the wiper part 221 will flow along the upper surface of the first cleaning section 2121 and be gradually reabsorbed by the cleaning member 212, and a small part of the sewage will flow along the second water guide surface 223 and drip onto the water receiving plate 230, which can reduce the dripping sewage.

[0102] When the wiper 220 is located on the side of the horizontal plane where the axis of the rotating part 211 is located away from the surface 20 to be cleaned, the water receiving plate 230 is arranged below the wiper 220 to receive the sewage dripping from below the wiper 220 .

[0103] For example, Figure 1 As shown, the water receiving plate 230 can be arranged on the side of the horizontal plane where the axis of the rotating part 211 is located away from the surface to be cleaned 20, that is, the water receiving plate 230 is also arranged above the axis of the rotating part 211. Figure 5 , Figure 5 This is a structural diagram of a cleaning device according to another embodiment of the present invention. The water receiving plate 230 may also be arranged on the side of the horizontal plane where the axis of the rotating part 211 is located facing the surface 20 to be cleaned, that is, the water receiving plate 230 is arranged below the axis of the rotating part 211.

[0104] Of course, in another embodiment, the wiper 220 can also be arranged on the side of the surface 20 to be cleaned facing the horizontal plane where the axis of the rotating part 211 is located, that is, the wiper 220 is arranged below the axis of the rotating part 211, and the wiper part 221 abuts against the lower surface of the first cleaning section 2121.

[0105] It is understandable that when the wiper plate 220 is located on the side of the horizontal plane where the axis of the rotating part 211 is located facing the surface to be cleaned 20, the water receiving plate 230 also needs to be arranged on the side of the horizontal plane where the axis of the rotating part 211 is located facing the surface to be cleaned 20.

[0106] In one embodiment, a first hydrophobic layer is provided on the surface of the wiper 220. By providing the first hydrophobic layer on the surface of the wiper 220, the surface tension of the wiper 220 can be reduced, so that the wiper 220 has better hydrophobicity, and the scraped sewage can flow into the sewage box 240 more smoothly and quickly, avoiding the sewage from sticking to the surface of the wiper 220, thereby reducing the sewage leaking or overflowing from the lower side of the wiper part 221.

[0107] In another embodiment, a second hydrophobic layer is provided on the surface of the water receiving plate 230. Similarly, by providing the second hydrophobic layer on the surface of the water receiving plate 230, the surface tension of the water receiving plate 230 can be reduced, so that the water receiving plate 230 has better hydrophobicity, so that the sewage dripping onto the water receiving plate 230 can quickly flow into the sewage box 240.

[0108] The materials of the first hydrophobic layer and the second hydrophobic layer can be the same, so that the first hydrophobic layer and the second hydrophobic layer can be formed on the surface of the wiper plate 220 and the surface of the water receiving plate 230 respectively in the same process using the same process steps, thereby improving the manufacturing efficiency.

[0109] The materials of the first hydrophobic layer and the second hydrophobic layer can be fluoride, silicide, etc. Specifically, fluoride can be sprayed on the surface of the wiper plate 220 and the surface of the water receiving plate 230 to form the first hydrophobic layer and the second hydrophobic layer, thereby reducing the surface tension of the wiper plate 220 and the water receiving plate 230, so that the sewage is not easy to stick to the surface of the wiper plate 220 and the water receiving plate 230.

[0110] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
