It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0031] At present, the common cleaning equipment on the market usually uses a scraper and a roller brush to achieve floor cleaning. The cleaning water flows out through the roller brush to absorb the stains, and then the friction between the scraper and the roller brush scrapes away the dirt to achieve the cleaning effect. Therefore, the roller brush and the scraper are interference fit. However, most of the existing cleaning equipment uses a fixed metal scraper to squeeze and rub against the roller brush. During long-term use, the fluff on the roller brush is constantly worn, so that the interference between the roller brush and the metal scraper becomes smaller and smaller, resulting in unclear scraping, water stains on the ground, and poor cleaning effect.

[0032] In view of the above problems, the present application provides a cleaning component and a cleaning device. The cleaning component is applied to the cleaning device to solve the problem that the friction between the scraper and the roller brush is large and the roller brush is easily worn, resulting in a reduction in the interference fit between the roller brush and the scraper. Figures 1 to 6 Shown is a specific implementation of the cleaning component and cleaning equipment provided by the present application.

[0033] Figure 1 A schematic structural diagram of an embodiment of the cleaning device 10 provided in the present application; Figure 2 A partial cross-sectional schematic diagram of an embodiment of the cleaning device 10 provided in the present application; Figure 3 A schematic structural diagram of an embodiment of a cleaning component provided in the present application; Figure 4 A schematic diagram of the structural decomposition of an embodiment of the cleaning component provided by the present application; Figure 5 A schematic diagram of the structure of the wiper assembly of the cleaning assembly provided in this application; Figure 6 A schematic cross-sectional view of the wiper assembly of the cleaning assembly provided in the present application.

[0034] like Figures 1 to 6As shown, the present application provides a cleaning device 10, which includes a cleaning component 200 and a roller brush 300. The roller brush 300 is used to directly contact the ground. The roller brush 300 is provided with a plurality of fluffs, and the fluffs can absorb the ground stains during the rolling process of the roller brush 300. The cleaning component 200 of the cleaning device 10 includes a base 210 and a wiper component 220. The roller brush 300 is rotatably arranged on the base 210; the base 210 has a mounting groove 211, and a mounting portion 221 is arranged in the mounting groove 211. The mounting portion 221 can be a water spraying component acting on the roller brush 300. A water outlet device and a drainage device (not shown in the figure) are arranged on the base 210. The water outlet device is connected with the mounting portion 221 to transport clean water to the mounting portion 221, and the mounting portion 221 sprays clean water to the roller brush 300 to clean the roller brush 300. The wiper assembly 220 is disposed in the mounting groove 211, and the wiper assembly 220 includes a scraper 222 and an elastic member. The scraper 222 is used to have an interference fit with the roller brush 300 to scrape dirt off the roller brush 300. The scraper 222 includes a wiper portion 2222, and the wiper portion 2222 is used to abut against the roller brush 300 and have an interference fit with the roller brush 300. When the roller brush 300 rotates, dirt on the roller brush 300 can be scraped off. The cleaning device 10 also includes an upper cover assembly 400, which is detachably fixed to the base 210 and is used to cover the cleaning assembly 200 and part of the roller brush 300.

[0035] like Figure 2 , Figure 6 As shown, in the embodiment provided by the present application, the scraper 222 is provided with a first through hole 2221 that passes through the scraper 222. The mounting portion 221 is provided with a second through hole 2211, and the elastic member is pre-deformed and penetrates the first through hole 2221 and the second through hole 2211, and is elastically pressed against the mounting portion 221 and the scraper 222 so that the scraper 222 has a tendency to move toward the roller brush 300. Therefore, when the roller brush 300 rotates to squeeze the scraper 222, the elastic member is greatly deformed by the pressure, and the scraper 222 moves in a direction away from the roller brush 300; when the roller brush 300 stops squeezing the scraper 222, no pressure is applied to the elastic member, and the elastic member returns to its original state to push the scraper 222 to move toward the roller brush 300. Thus, the scraper 222 and the roller brush 300 achieve elastic friction contact. Compared with the rigid contact between the scraper 222 and the roller brush 300, the elastic friction contact can reduce the wear on the roller brush 300, ensure that the scraper 222 always maintains a reasonable interference fit with the roller brush 300, and extend the service life of the roller brush 300. In addition, because the elastic member is installed in the mounting portion 221, the mounting portion 221, the scraper 222 and the elastic member form a whole, and there is no need to add a structure outside the mounting portion 221. Therefore, while achieving elastic friction contact between the scraper 222 and the roller brush 300, the internal space of the cleaning component is saved, avoiding the problem of sealing.

[0036] In order to improve the cleaning power of the roller brush 300, Figures 4 to 6 As shown, the cleaning assembly 200 of the present application further includes a comb plate 224, which is arranged on the side of the scraper 222 away from the mounting portion 221 to increase the friction effect on the roller brush 300. A through third through hole 2241 is provided on the comb plate 224, and an elastic member is provided through the first through hole 2221, the second through hole 2211 and the third through hole 2241. The elastic member is compressed and elastically abuts against the mounting portion 221, the scraper 222 and the comb plate 224 so that the scraper 222 and the comb teeth have a tendency to move toward the roller brush 300. In the embodiment provided by the present application, in order to facilitate the assembly of the wiper assembly 220, the first through hole 2221, the second through hole 2211 and the third through hole 2241 are of the same size. In some other embodiments, the sizes of the first through hole 2221, the second through hole 2211 and the third through hole 2241 may be different, and are set according to actual application needs.

[0037] In the embodiment provided in the present application, the number of elastic members is two, and the corresponding settings are that the number of first through holes 2221 is two, the number of second through holes 2211 is two, and the number of third through holes 2241 is two. During actual application, the number of elastic members can be adjusted as needed, and the number of first through holes 2221, second through holes 2211 and third through holes 2241 can also be adjusted accordingly.

[0038] In order to improve the overall stability of the wiper assembly 220, as Figure 6 As shown, in the embodiment provided by the present application, one end of the elastic member extending from the comb plate 224 is a fixing portion 2231, and the fixing portion 2231 abuts against the side of the comb plate 224 away from the scraper 222, so that the mounting portion 221, the scraper 222 and the comb plate 224 fit closely. In the embodiment provided by the present application, the fixing portion 2231 extends toward the roller brush 300 so that the fixing portion 2231 abuts against the side of the comb plate 224 away from the scraper 222. In the embodiment where the comb plate 224 is not provided, the fixing portion 2231 abuts against the side of the scraper 222 away from the mounting portion 221.

[0039] The elastic member in the embodiment provided in the present application is a metal spring 223. In some other embodiments, the elastic member may be a spring, a torsion spring, an elastic soft rubber or the like. Figure 6 As shown, the metal spring 223 has a symmetrically arranged first bending portion 2232 and a second bending portion 2233. Therefore, the fixing portion 2231 also has a symmetrically arranged first fixing portion 2231a and a second fixing portion 2231b. When the scraper 222 and the comb plate 224 move toward or away from the roller brush 300, the fixing portion 2231 always contacts the comb plate 224, so as to keep the mounting portion 221, the scraper 222 and the comb plate 224 stable in the vertical direction.

[0040] like Figures 4 to 6 As shown, the mounting portion 221 includes a first plate 2212 and a second plate 2213 that are arranged opposite to each other. The first plate 2212 is arranged on a side away from the second plate 2213 facing the roller brush 300. The second through hole 2211 is located between the first plate 2212 and the second plate 2213, so the metal spring 223 is passed through the first plate 2212 and the second plate 2213. Compared with the technical solution in which the elastic member is arranged outside the mounting portion 221, the embodiment provided by the present application does not need to arrange extra parts outside the mounting portion 221, which can effectively save the internal space of the component and avoid the problem of sealing.

[0041] The embodiment provided in this application provides a method for fixing the metal spring 223 to the mounting portion 221. Figure 6 As shown, the side of the first plate 2212 facing the second plate 2213 is the first surface 2212a, and the side of the second plate 2213 facing the first plate 2212 is the second surface 2213a. The first surface 2212a and the second surface 2213a are symmetrically provided with a stopper 2214. The first bending portion 2232 and the second bending portion 2233 of the metal spring 223 are provided with a clamping portion 2234 matching the clamping portion 2214, and the clamping portion 2234 cooperates with the clamping portion 2214 to fix the metal spring 223 to the mounting portion 221. The present application provides one embodiment of the form of the clamping portion and the clamping portion, the clamping portion 2214 protrudes from the plane, the clamping portion 2234 is a recess matching the clamping portion 2214, and the structure of the clamping portion 2214 and the clamping portion 2234 is not limited to the embodiment provided in the present application, and other methods that can realize the fixing of the elastic member to the mounting portion 221 are all possible.

[0042] In order to limit the distance that the scraper 222 moves toward the roller brush 300, as shown in FIG. Figure 4 , Figure 6 As shown, in the embodiment provided by the present application, a first stop portion 2223 is provided at the other end of the scraper 222 away from the wiper portion 2222, and the first stop portion 2223 extends toward the mounting portion 221. When the roller brush 300 stops squeezing the scraper 222, the elastic member returns to its original state and drives the scraper 222 to move toward the roller brush 300, and the first stop portion 2223 abuts against the outer wall of the mounting portion 221, limiting the movement of the scraper 222 toward the roller brush 300, so that the scraper 222 remains stationary, limiting the distance between the wiper portion 2222 and the roller brush 300 to control the maximum friction between the wiper portion 2222 and the roller brush 300, and more effectively protecting the roller brush 300. In the embodiment provided by the present application, two first stop portions 2223 are provided, but in actual application, the number of the first stop portions 2223 can be adjusted as needed.

[0043] like Figure 4 , Figure 6 As shown, in the embodiment provided by the present application, the comb plate 224 includes a comb tooth portion 2242 for abutting against the roller brush 300. In order to limit the distance of the comb plate 224 moving toward the roller brush 300, a second stop portion 2243 is provided at the other end away from the comb tooth portion 2242, and the second stop portion 2243 extends toward the mounting portion 221. When the roller brush 300 stops squeezing the comb plate 224, the elastic member returns to its original state and drives the comb plate 224 to move toward the roller brush 300. The second stop portion 2243 abuts against the outer wall of the mounting portion 221, limiting the movement of the comb plate 224 toward the roller brush 300, keeping the comb plate 224 in a stationary state, limiting the distance between the comb tooth portion 2242 and the roller brush 300 to control the maximum friction between the comb tooth portion 2242 and the roller brush 300, and more effectively protecting the roller brush 300. In the embodiment provided in the present application, three second stop portions 2243 are provided, but in actual application, the number of the second stop portions 2243 can be adjusted as required.

[0044] like Figures 2 to 4 As shown, in the embodiment provided by the present application, the second plate 2213, the first stop portion 2223 and the second stop portion 2243 are arranged on the inner wall of the mounting groove 211 away from the side of the first plate 2212. The metal spring 223 has a maximum bending distance. If the bending degree of the metal spring 223 exceeds the maximum bending distance, the metal spring 223 cannot restore its original shape, resulting in the metal spring 223 being unable to adjust the elastic contact between the scraper 222 and the roller brush 300. In order to prevent the metal spring 223 from being unable to restore its original shape, the distance between the first stop portion 2223 and / or the second stop portion 2243 and the inner wall of the mounting groove 211 is smaller than the maximum bending distance of the metal spring 223. When the roller brush 300 squeezes the scraper 222 or the comb plate 224, the first stop portion 2223 or the second stop portion 2243 abuts against the inner wall of the mounting groove 211, and the scraper 222 or the comb plate 224 cannot continue to move away from the roller brush 300, thereby ensuring the elasticity of the metal spring 223.

[0045] like Figures 2 to 4 As shown, in the embodiment provided in the present application, the cleaning assembly 200 includes a water spray assembly, the first plate body 2212 is a water outlet plate of the water spray assembly, the second plate body 2213 is a waterway plate of the water spray assembly, and the second through hole 2211 is located between the water outlet plate and the waterway plate. The water spray assembly also includes a nozzle, which is used to be set toward the roller brush. The water from the water outlet device of the cleaning equipment flows into the water spray assembly through the waterway plate, and then flows from the water outlet plate of the water spray assembly to the nozzle, and the nozzle sprays the water flow evenly to the roller brush 300.

[0046] The present application provides a cleaning component and a cleaning device, wherein the cleaning component 200 includes a base 210 and a wiper component 220, wherein the base 210 is at least used to rotate and set a roller brush 300, and the base 210 has a mounting portion 221; the wiper component 220 includes a scraper 222 and an elastic member, wherein the scraper 222 includes a wiper portion 2222, and the wiper portion 2222 is used to abut against the roller brush 300, wherein the scraper 222 has a first through hole 2221, and the mounting portion 221 has a second through hole 2211, wherein the elastic member is inserted through the first through hole 2221 and the second through hole 2211, and elastically abuts against the mounting portion 221 and the scraper 222 under pressure. By inserting the elastic member through the first through hole and the second through hole, and elastically abutting against the mounting portion and the scraper under pressure, the characteristics of the elastic member are used to make the wiper portion and the roller brush maintain elastic friction contact, and the interference is stable, thereby solving the problem that the roller brush is easily worn, and achieving a good cleaning effect. At the same time, the integrated setting of the wiper assembly saves installation space and solves the problem of difficult waterproof sealing.

[0047] The above description is only an implementation method of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
