[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] In addition, the present invention may repeat reference numerals and / or reference letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or arrangements discussed. In addition, the present invention provides examples of various specific processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0045] When the cleaning device performs cleaning work, it generally cleans the operation surface through the cleaning component on the cleaning device. However, limited by the structure of the cleaning device itself, it is difficult for the cleaning device to cover the corners of the operation surface (such as the corner of a wall, the edge of a wall, etc.), so it is impossible to clean the water at the corners of the operation surface. Moreover, after the cleaning device generally uses a wet cloth to clean the operation surface, water may be left on the operation surface, and the water may contain dust that has not been completely removed, resulting in water stains left on the operation surface after the water evaporates. If water remains on the operation surface, it is easy to slip, causing a safety hazard.

[0046] Next, the present invention will be described in conjunction with the accompanying drawings and with reference to specific embodiments:

[0047] An embodiment of the first aspect of the present invention provides a cleaning device. Please refer to Figures 1 to 2 , including a device body 100 and a wiper component 200. The wiper component 200 is connected to the device body 100 and at least partially extends out of the device body 100.

[0048] Using the wiper 200 to scrape the water at the corner positions of the operation surface, reducing the cleaning dead corners of the cleaning device. The part of the wiper 200 extending out of the device body 100 can extend to the corner positions of the operation surface to clean the parts not covered by the device body 100, improving the cleaning ability of the cleaning device; when the cleaning device moves on the operation surface, the part of the wiper 200 extending out of the device body 100 can also scrape the water at the positions on the periphery of the device body 100, increasing the effective cleaning area of the cleaning device, and thus improving the cleaning efficiency of the cleaning device.

[0049] The wiper 200 of the cleaning device according to the embodiment of the present utility model can remove the residual water after the cleaning device cleans the operation surface, and the wiper 200 of the cleaning device can also remove the original sewage on the operation surface to ensure the dryness of the operation surface, avoid the situation that water remains on the operation surface and causes the operation surface to slip, and reduce potential safety hazards. The operation surface can be the ground, wall, desktop, building exterior wall, etc. The corner positions of the operation surface can be the edge of the wall or the corner, etc., and the corner positions of the operation surface can also be the edge of the operation surface, such as the edge of the desktop.

[0050] It can be understood that at least part of the wiper 200 extends out of the device body 100, generally the end of the wiper 200 extends out of the device body 100, and of course, it can also be the middle part of the wiper 200 extending out of the device body 100; it can be one end of the wiper 200 extending out of the device body 100, or multiple ends of the wiper 200 extending out of the device body 100 respectively, and the embodiment of the present utility model does not make special limitations on this. When the cleaning device moves on the operation surface, the wiper 200 moves with the cleaning device on the operation surface to remove the water on the operation surface; a driving component of the wiper 200 can be set on the cleaning device to control the wiper 200, which is beneficial to the progress of the wiper work.

[0051] In some embodiments, please refer to Figure 2 , the wiper 200 includes a main wiper 210 and an edge wiper 220. The main wiper 210 is connected to the device body 100, and the main wiper 210 can scrape the water on the operation surface that the cleaning device has passed; at least part of the edge wiper 220 extends out of the device body 100, which can scrape the water on the periphery of the cleaning device, and the part of the edge wiper 220 extending out of the device body 100 can extend to the corner positions of the operation surface to scrape the water at the corner positions of the operation surface.

[0052] Through the cooperation of the main wiper 210 and the edge wiper 220 in the embodiment of the present utility model, the wiper area and wiper efficiency of the cleaning device can be improved, which is beneficial to the cleaning device to comprehensively clean the operation surface and avoid the occurrence of sanitary dead corners.

[0053] In some embodiments, please refer to Figure 2 , the main wiper 210 and the edge wiper 220 are at least partially overlapped to prevent water from passing between the main wiper 210 and the edge wiper 220, which may affect the water scraping effect; the main wiper 210 and the edge wiper 220 can be overlapped along the cleaning direction of the cleaning device. When the cleaning device moves on the operation surface, under the action of the wiper 200, the water in the area passed by the cleaning device gathers on one side of the wiper 200 close to the cleaning direction. The main wiper 210 and the edge wiper 220 are at least partially overlapped, so that the gathered water cannot leak between the main wiper 210 and the edge wiper 220 along the cleaning direction of the cleaning device, thus ensuring the water scraping effect of the wiper 200. The main wiper 210 and the edge wiper 220 can be partially overlapped or completely overlapped. The embodiments of the present invention do not limit this. The main wiper 210 and the edge wiper 220 can be closely arranged to reduce the gap between the main wiper 210 and the edge wiper 220; a connecting piece or a sealing piece can also be arranged between the main wiper 210 and the edge wiper 220 to prevent water from passing between the main wiper 210 and the edge wiper 220.

[0054] In some embodiments, the main wiper 210 and the edge wiper 220 are integrally formed, which can improve the production efficiency and reduce the assembly steps; the integrally formed design can prevent gaps from being generated between the main wiper 210 and the edge wiper 220 and improve the water scraping effect.

[0055] In some embodiments, please refer to Figure 3 , the device body 100 includes a water absorption area 110, and a water guiding surface 230 is formed on the wiper 200. The water guiding surface 230 can be used to guide the water on the operation surface to the water absorption area 110; the water absorption area 110 can gather the water on the wiper 200, which is convenient for the recovery of sewage, and at the same time can reduce the burden on the wiper 200, so that the wiper 200 can perform the next round of water scraping work. The cleaning device can include a water suction pump (not shown in the figure) and a sewage tank (not shown in the figure). The water suction pump can be used to suck the sewage gathered on the water absorption area 110 into the sewage tank to achieve the purpose of sewage recovery. When the cleaning device moves on the operation surface, the water on the operation surface flows along the water guiding surface 230 to the water absorption area 110, and the water suction pump sucks the water in the water absorption area 110 into the sewage tank.

[0056] The wiper member 200 can be bent to form a curved water guiding surface 230, which is conducive to the accumulation of water on the wiper member 200. The wiper member 200 can be bent toward the cleaning direction of the cleaning device to form a concave water absorption area 110. When the cleaning device moves on the operation surface, by using the acting force of the movement of the cleaning device, the water on the cleaning area can flow along the curved water guiding surface 230 to the water absorption area 110, improving the wiper efficiency. It can be that the main wiper member 210 is curved and the edge wiper member 220 is linear, which is conducive to the edge wiper member 220 extending to the corners of the operation surface. Of course, in other embodiments, the wiper member 200 can also be linear or other shapes, and the specific shape of the wiper member 200 in the embodiments of the present utility model is not particularly limited.

[0057] In some embodiments, please refer to Figure 3 , the edge wiper member 220 is located in the cleaning direction of the main wiper member 210 (such as Figure 3 the a direction in ), and the part of the edge wiper member 220 extending out of the device body 100 guides the water at the corner position of the operation surface to the main wiper member 210, and then the water is collected into the sewage tank through the water suction pump. The wiper member 200 moves in the cleaning direction, and the water moves in the opposite direction relative to the wiper member 200. If the main wiper member 210 is located in the cleaning direction of the edge wiper member 220, the water on the edge wiper member 220 will directly flow out between the main wiper member 210 and the edge wiper member 220, which is not conducive to the subsequent sewage recovery work. The main wiper member 210 is bent to form the water absorption area 110, and the edge wiper member 220 is located in the cleaning direction of the main wiper member 210, which is convenient for the water on the edge wiper member 220 to gather in the water absorption area 110.

[0058] In some embodiments, the cleaning device further includes an elastic member (not shown in the figure). The elastic member connects the device body 100 and the wiper member 200. By using the elastic member, the wiper member 200 can move relative to the device body 100, improving the flexibility of the wiper member 200. When the cleaning device moves on an uneven operation surface, the wiper member 200 can float up and down according to the uneven degree of the operation surface. While ensuring the wiper effect, the device body can maintain stable driving, reduce the shaking of the device body during work, and improve the stability of the cleaning device. When the wiper member 200 is located at the raised part of the operation surface, the wiper member 200 squeezes toward the device body 100, the wiper member 200 floats up, and the elastic member is compressed; when the wiper member 200 is located at the sunken part of the operation surface, the elastic member releases elastic force, and the wiper member 200 presses down. Generally, the elastic member is a spring.

[0059] The elastic member includes at least one of a first elastic member and a second elastic member. The first elastic member is used to connect the device body 100 and the edge wiper 220, and the second elastic member is used to connect the device body 100 and the main wiper 210. Only the first elastic member can be provided to ensure the water scraping effect of the edge wiper 220 on the corner position of the operation surface, and at the same time, it can adapt to the situation where the corner position and other positions of the operation surface may not be in the same plane. Only the second elastic member can also be provided to ensure the water scraping effect of the main wiper 210 on the operation surface. In other embodiments, the first elastic member and the second elastic member can also be provided to improve the flexibility of the wiper 200, so that both the main wiper 210 and the edge wiper 220 can move relative to the device body 100 to adapt to different cleaning environments.

[0060] In some embodiments, refer to Figures 3 to 4 , a fixing groove 310 for the wiper 200 is provided on the device body 100. The fixing groove 310 fixes the wiper 200 on the device body 100, which is beneficial for the wiper 200 to maintain stability during operation. Through the fixing groove 310, the installation position of the wiper 200 can be quickly locked during installation, which is beneficial for quickly and accurately installing the wiper 200. A part of the wiper 200 extends out of the notch of the fixing groove 310, and through the notch of the fixing groove 310, the wiper 200 can scrape the water on the operation surface.

[0061] The cleaning device may include a cleaning bracket 300, and the fixing groove 310 is provided on the cleaning bracket 300. Using the cleaning bracket 300 to support the main wiper 210 and the edge wiper 220 is beneficial for ensuring the relative position between the main wiper 210 and the edge wiper 220. The cleaning device may include a main cleaning member 400, and the main cleaning member 400 can clean dust and the like on the operation surface. The main cleaning member 400 may be a cleaning cloth. After the cleaning cloth is moistened, it can clean the operation surface, and the wiper 200 can further remove the remaining water after the cleaning cloth cleans. Setting the main cleaning member 400 and the wiper 200 on the cleaning bracket 300 can maintain the relative position between the main cleaning member 400 and the wiper 200, which is beneficial for the wiper 200 to accurately remove the water left on the operation surface after the main cleaning member 400 cleans. Two fixing grooves 310 may be provided, and the two fixing grooves 310 are respectively used to fix the main wiper 210 and the edge wiper 220.

[0062] In some embodiments, refer to Figures 5 to 6, a limiting protrusion 311 is provided on the side wall of the fixing groove 310, and a guiding protrusion 241 is provided on the wiper 200. The guiding protrusion 241 moves between the limiting protrusion 311 and the bottom of the fixing groove 310. By restricting the movement range of the guiding protrusion 241 by the limiting protrusion 311, the movement range of the wiper 200 is limited, preventing the wiper 200 from disengaging from the cleaning bracket 300.

[0063] One end of the elastic member abuts against the bottom of the fixing groove 310, and the other end is connected to the wiper 200. By using the elasticity of the elastic member, the wiper 200 moves in the direction from the bottom of the fixing groove 310 to the opening of the fixing groove 310; when the wiper 200 moves to the protruding position of the operation surface, the wiper 200 moves towards the bottom of the fixing groove 310, compressing the elastic member; when the wiper 200 moves to the concave position or flat position of the operation surface, the elastic member releases its elastic force, and the wiper 200 moves away from the bottom of the fixing groove 310 until the guiding protrusion 241 abuts against the limiting protrusion 311.

[0064] In some embodiments, refer to Figures 5 to 6 , a first recess 510 is provided on the guiding protrusion 241. The first recess 510 is adapted to reduce the friction between the limiting protrusion 311 and the fixing groove 310. By providing the first recess 510, the contact surface between the limiting protrusion 311 and the fixing groove 310 is reduced, thereby reducing the friction between the wiper 200 and the fixing groove 310, enabling the wiper 200 to move smoothly within the fixing groove 310. The first recess 510 can be provided on one side of the guiding protrusion 241 facing the side wall of the fixing groove 310 to reduce the contact area between the guiding protrusion 241 and the fixing groove 310.

[0065] In some embodiments, a second recess 520 is provided on the limiting protrusion 311. The second recess 520 is adapted to reduce the friction between the limiting protrusion 311 and the wiper 200. By providing the second recess 520, the contact surface between the limiting protrusion 311 and the wiper 200 is reduced, thereby reducing the friction between the wiper 200 and the fixing groove 310, preventing the limiting protrusion 311 from hindering the movement of the wiper 200 inside the fixing groove. The second recess 520 can be provided on one side of the limiting protrusion 311 facing the wiper 200 to reduce the contact area between the limiting protrusion 311 and the wiper 200.

[0066] In some embodiments, refer to Figure 6The sidewall of the fixing groove 310 is provided with an insertion opening 312, through which the wiper member 200 partially extends out of the device body 100. Through the insertion opening 312, a portion of the wiper member 200 can be installed in the fixing groove 310 to secure the wiper member 200; the other portion of the wiper member 200 extends out of the device body 100 through the insertion opening 312, allowing the wiper member 200 to clean water from the corners of the operating surface.

[0067] In some embodiments, see Figure 7 The wiper 200 includes a wiper portion 250 and a connecting portion 260. The wiper portion 250 is connected to the connecting portion 260, and the connecting portion 260 is fixed to the device body 100. At least a portion of the wiper portion 250 extends out of the notch of the fixing groove 310 to perform wiping work; the wiper portion 250 is inclined from the connecting portion 260 toward the side opposite to the cleaning direction. When the wiper 200 moves forward, the inclination of the wiper portion 250 will help push the water toward the cleaning direction of the cleaning device. If the wiper portion 250 is vertical or inclined in the cleaning direction, water may remain on the wiper 200, affecting its wiping effect and causing water to form residue or residue on the operating surface. The inclined design allows the wiper portion 250 to better fit the surface of the operating surface when wiping, ensuring that water can be removed smoothly without remaining or forming residue on the operating surface. In addition, the inclined arrangement of the wiper portion 250 can reduce the friction between the wiper portion 250 and the operating surface, thereby reducing the wear and damage of the wiper element 200 and making it more durable.

[0068] In some embodiments, see Figures 7 to 8 The wiper element 200 includes a fixing base 240, which is fixed to the device body 100. The fixing base 240 is provided with a mounting groove 242, and the connecting portion 260 is at least partially inserted into the mounting groove 242. The fixing base 240 facilitates the fixing and installation of the wiper element 200, thereby ensuring the stability of the wiper element 200. The guide protrusion 241 is provided on the fixing base 240 to facilitate the processing of the guide protrusion 241. The mounting groove 242 and the connecting portion 260 can be an interference fit to firmly fix the wiper element 200 to the fixing base 240. The fixing base 240 can be a hard structure, such as metal or hard plastic, to facilitate the fit between the wiper element 200 and the fixing groove 310.

[0069] In some embodiments, see Figures 7 to 8, the part of the wiper 200 extending out of the device body 100 is the edge end 270, and at least part of the edge end 270 is made of an elastic material. The elastic material enables the wiper 200 to deform freely under stress, so that the wiper 200 can adapt to the corner positions of different types of operating surfaces. The elastic material endows the wiper 200 with good resilience and can quickly return to its original state after the external force disappears. For example, during the cleaning process of the cleaning device on the corner of a wall, the edge end 270 abuts against the wall and deforms, enabling the wiper 200 to fit the corner better for cleaning and reducing cleaning dead corners. The wiper part 250 is made of soft rubber material, which is convenient for wiper work; the connecting part 260 and the wiper part 250 are integrally formed to improve production efficiency, and the wiper part 250 can be fixed by inserting the connecting part 260 into the installation groove 242.

[0070] In some embodiments, please refer to Figures 7 to 8 , an opening 243 is provided on the side wall of the installation groove 242, and the opening 243 communicates with the notch of the installation groove 242; the edge end 270 extends out of the device body 100 through the opening 243. The opening 243 can be inclined to facilitate inserting the connecting part 260 into the installation groove 242 and reduce the installation resistance.

[0071] In some embodiments, please refer to Figure 8 , the cleaning device further includes an edge cleaning member 600, which is connected to the device body 100, and at least part of the edge cleaning member 600 extends out of the device body 100; the edge cleaning member 600 can be used to clean dust and the like at the corner positions of the operating surface, and can also clean the peripheral side of the device body 100 to increase the effective cleaning area of the cleaning device. The wiper 200 is located on the side of the edge cleaning member 600 facing away from the cleaning direction. After the edge cleaning member 600 finishes cleaning, the wiper 200 can scrape off the water remaining after the edge cleaning member 600 finishes cleaning.

[0072] In some embodiments, please refer to Figure 8 , the length of the part of the wiper 200 extending out of the device body 100 is greater than the length of the part of the cleaning member extending out of the device body 100, so as to ensure that the wiper 200 can scrape off the water remaining after the edge cleaning member 600 finishes cleaning. At the same time, the part of the wiper 200 extending out of the device body 100 is relatively long. When the edge cleaning member cleans places such as the corner of a wall, it can ensure that the wiper 200 can fit the wall for scraping water on the ground and improve the wiper effect.

[0073] In some embodiments, please refer to Figure 8, the minimum angle between the extending direction of the wiper member 200 and the cleaning direction is less than ninety degrees. This helps the water on the wiper member 200 to gather along the wiper member 200 towards the device body 100 when the wiper member 200 moves forward. If the wiper member 200 is perpendicular to the cleaning direction or the minimum angle with the cleaning direction is greater than ninety degrees, the water may disperse along the wiper member 200 away from the device body 100, affecting its water wiping effect and making it difficult to collect the water on the wiper member 200.

[0074] The cleaning device includes but is not limited to a floor sweeping robot, a mopping and sweeping integrated robot, a floor washer, a mop, etc.

[0075] In the present utility model, unless otherwise clearly specified and defined, the first feature being "above" or "below" the second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the first feature has a higher horizontal height than the second feature. The first feature being "below", "under" and "beneath" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the first feature has a lower horizontal height than the second feature.

[0076] It should be noted that all the directional indications in the embodiments of the present utility model are only used to explain the relative positional relationship, movement conditions, etc. between components in a specific posture.
