[0026] Please refer to Figures 1 to 3 , Figure 2 , Figure 1 is a perspective structural schematic diagram of an embodiment of a floor brush assembly of the present application; Figure 2 is a partial structural schematic diagram of an embodiment of a floor brush assembly of the present application; Figure 3 is a cross-sectional structural schematic diagram of an embodiment of a floor brush assembly of the present application.

[0027] An embodiment of the present application provides a floor brush assembly 100. The floor brush assembly 100 is used for a cleaning device (not shown in the figure) and cooperates with other modules of the cleaning device to realize cleaning. The floor brush assembly 100 includes a shell 110, a rolling brush 120 and a rotating member 101. The shell 110 can play a role of supporting and protecting the internal parts. The rolling brush 120 is rotatably arranged in the shell 110, and the rolling brush 120 can transfer dirt on the surface to be cleaned to the surface of the rolling brush 120 by rolling, and also facilitate movement on the surface to be cleaned. The rotating member 101 includes a water distribution piece 130 and a cleaning piece 150 connected with each other. The rotating member 101 has a rotating shaft 140, and the rotating member 101 is installed on the shell 110 through the rotating shaft 140. The water distribution piece 130 can spray clean water in the cleaning device to the surface of the rolling brush 120, so as to facilitate the rolling brush 120 to clean the dirt on the surface to be cleaned. The cleaning piece 150 is used to contact the rolling brush 120 and extrude the rolling brush 120 when the rolling brush 120 rotates, so as to scrape off solid stains on the surface of the rolling brush 120 and extrude the sewage in the rolling brush 120.

[0028] In an embodiment of the present application, the floor brush assembly 100 further includes a torsional spring 160. The torsional spring 160 is arranged at the rotating shaft 140. One end of the torsional spring 160 abuts against the shell 110, and the other end abuts against the rotating member 101. The torsional spring 160 has a torsional force to drive the rotating member 101 to rotate and approach the rolling brush 120, so that the cleaning piece 150 abuts against the rolling brush 120.

[0029] When the rolling brush 120 in the present application is installed in the shell 110, the rolling brush 120 will be extruded with the cleaning member 150, so that the rotating member 101 will be rotated in the direction away from the rolling brush 120, at this time the torsional spring 160 will be deformed or further deformed to store torsional force, and the cleaning member 150 can be elastically and rotatably floated relative to the rolling brush 120. Under the action of the torsional force of the torsional spring 160, the rotating member 101 has a tendency to rotate towards the rolling brush 120, the cleaning member 150 is tightly attached to the rolling brush 120, and the cleaning member 150 and the bristles of the rolling brush 120 can maintain a certain extrusion force and a certain interference insertion amount, so as to effectively scrape off the solid stains on the surface of the rolling brush 120 and squeeze out the sewage in the rolling brush 120.

[0030] Please continue to refer to Figure 4 , Figure 4 is another cross-sectional structure diagram of an embodiment of the floor brush assembly in the present application, in which the diameter of the rolling brush is relatively Figure 3 smaller than that in the embodiment shown in FIG. 6. With the increase of the use time, even if the bristles of the rolling brush 120 are worn and collapsed, the diameter of the rolling brush 120 becomes smaller, the torsional force stored in the torsional spring 160 can be partially released, and the rotating member 101 is driven to rotate towards the rolling brush 120 until the cleaning member 150 is tightly attached to the rolling brush 120. The cleaning member 150 can still maintain a relatively stable extrusion force and a stable interference insertion amount to the rolling brush 120, so as to maintain the water squeezing effect and the solid stain removing effect of the cleaning member 150 to the rolling brush 120, reduce or even avoid the problems that the cleaning member 150 does not sufficiently contact with the rolling brush 120, the cleaning effect of the surface to be cleaned is poor, the residual water on the surface to be cleaned increases, and the anti-winding ability of the rolling brush 120 decreases, thereby prolonging the service life of the rolling brush 120 and ensuring the long-term stability of the performance of the floor brush assembly 100 and the cleaning equipment product, and improving the user experience.

[0031] At the same time, since the rotating member 101 in the present application can rotate, the cleaning member 150 is tightly attached to the rolling brush 120 by the torsional force of the torsional spring 160, even if the rolling brush 120 of different diameter specifications is replaced, the cleaning member 150 can still maintain sufficient stable interference insertion amount to the rolling brush 120, so as to maintain the water squeezing effect and the solid stain removing effect of the cleaning member 150 to the rolling brush 120, and the floor brush assembly 100 in the present application has good compatibility and strong universality.

[0032] In addition, the cleaning member 150 and the water separating member 130 in the present application are connected with each other and synchronously rotate as the rotating member 101, and the rotation of the cleaning member 150 does not interfere with the water separating member 130, and the structures of the two are more simple and compact. The torsional spring 160 in the present application has a simple structure and low cost, the torsional spring 160 is installed at the rotating shaft 140, and the two ends of the torsional spring 160 abut against the shell 110 and the rotating member 101, respectively, without occupying other space in the shell 110, without the need to change the specifications and position layout of other parts, without greatly changing and affecting the space construction of the floor brush assembly 100, and with wide application range.

[0033] It should be further noted that the torsion spring 160 in the present application is arranged at the rotating shaft 140, and the torsion spring 160 is stable in position and form, and the torsion force of the torsion spring 160 can fully act on the driving of the rotating member 101 to rotate, thereby improving the rotation stability of the rotating member 101 and effectively ensuring that the cleaning member 150 and the rolling brush 120 maintain a relatively stable extrusion force and interference amount.

[0034] Specifically, the rolling brush 120 is detachably arranged in the shell 110, which is beneficial to the assembly of the floor brush assembly 100 and facilitates the cleaning and replacement of the rolling brush 120.

[0035] In some embodiments, the shell 110 is provided with a cover 115 and a suction inlet 116. When the floor brush assembly 100 is cleaning the surface to be cleaned, the dirt is sucked away through the suction inlet 116. The rotating member 101 is rotatably arranged between the suction inlet 116 and the cover 115. At this time, the rolling brush 120 is in contact with and extruded by the rotating member 101, and the dirt falling from the rolling brush 120 can be sucked away through the suction inlet 116, thereby improving the cleaning efficiency.

[0036] Further, when the rotating member 101 is arranged between the suction inlet 116 and the cover 115, the cleaning member 150 is located between the water distribution member 130 and the suction inlet 116. In the normal working state of the floor brush assembly 100, the rolling brush 120 first contacts and is extruded by the cleaning member 150, and the cleaning member 150 can preferentially scrape off the water and solid stains on the rolling brush 120, and then the water distribution member 130 sprays clean water to the cleaned area of the rolling brush 120, and the dirt is sucked away through the suction inlet 116. The water distribution member 130 and the cleaning member 150 are reasonably arranged, thereby improving the cleaning effect of the rolling brush 120.

[0037] Alternatively, in some embodiments, the rotating member 101 is rotatably arranged in the cover 115. Since the cover 115 is usually reversibly or detachably arranged in the shell, and the rotating member 101 is rotatably arranged in the cover 115, when it is necessary to disassemble the rotating member 101, only the cover 115 needs to be disassembled from the shell 110, so that the rotating member 101 can be disassembled, thereby improving the convenience of installing and cleaning the rotating member 101.

[0038] In the above embodiments, the rotating connection between the rotating member 101 and the shell 110 can be achieved by the water distribution member 130 being rotatably arranged in the shell 110 through the rotating shaft 140, and the cleaning member 150 being arranged in the water distribution member 130; or the rotating connection between the rotating member 101 and the shell 110 can be achieved by the cleaning member 150 being rotatably arranged in the shell 110 through the rotating shaft 140, and the water distribution member 130 being arranged in the cleaning member 150.

[0039] Please continue to refer to Figure 3 and Figure 4In some embodiments, the upper end of the water distribution member 130 is rotatably arranged on the housing 110 via the rotating shaft 140, and the cleaning member 150 is arranged on the lower end of the water distribution member 130. In the normal working state of the floor brush assembly 100, the rotating brush 120 first contacts and is pressed by the cleaning member 150, so that the cleaning member 150 can preferentially scrape off the sewage and solid stains on the rotating brush 120, and then the water distribution member 130 sprays clean water to the area of the rotating brush 120 after cleaning. The layout of the water distribution member 130 and the cleaning member 150 is reasonable, which improves the cleaning effect of the rotating brush 120. Moreover, the cleaning member 150 and the rotating shaft 140 are respectively arranged at the upper and lower ends of the water distribution member 130, and the torsional force of the torsion spring 160 can drive the cleaning member 150 to achieve a larger rotation range and torque effect, thereby improving the cleaning effect of the cleaning member 150 on the rotating brush 120.

[0040] Please continue to refer to Figure 5 , Figure 5 is an exploded structural schematic diagram of an embodiment of the floor brush assembly of the present application. The cleaning member 150 includes a scraping strip 151 and a comb tooth 152. The comb tooth 152 is arranged between the scraping strip 151 and the suction inlet 116. The scraping strip 151 can fully press the bristles of the rotating brush 120 to squeeze out the sewage in the rotating brush 120. The comb tooth 152 can cut and hook the hair on the rotating brush 120, thereby effectively preventing the hair from winding around the rotating brush 120. The comb tooth 152 is located between the scraping strip 151 and the suction inlet 116, which is also conducive to the comb tooth 152 being inserted into the bristles of the rotating brush 120 before the scraping strip 151 presses the rotating brush 120, and removing the hair.

[0041] Specifically, please refer to Figure 3 When the rotating brush 120 is in a relatively new state, the bristles of the rotating brush 120 are relatively fluffy, and the overall diameter of the rotating brush 120 is relatively large. The rotating brush 120 is installed on the housing 110, and the front edge of the scraping strip 151 and the comb tooth 152 has a pressing force, which drives the water distribution member 130 to rotate away from the rotating brush 120 and compress the torsion spring 160. The front edge of the scraping strip 151 and the comb tooth 152 can be fully inserted into the bristles of the rotating brush 120. Please refer to Figure 4 When the bristles of the rotating brush 120 are worn or collapsed, the bristles of the rotating brush 120 are relatively compact, and the overall diameter of the rotating brush 120 is reduced. Under the action of the torsional force of the torsion spring 160, the water distribution member 130 moves a certain angle towards the rotating brush 120, so that the front edge of the scraping strip 151 and the comb tooth 152 maintains the depth of the bristles of the rotating brush 120, and maintains the pressing force and the interference insertion amount of the rotating brush 120.

[0042] Further, the scraping strip 151 and the water distribution member 130 can be connected by clamping, bonding or fasteners. The comb tooth 152 and the scraping strip 151 are connected by clamping, bonding or fasteners.

[0043] In some embodiments, the cleaning member 150 can also include only the scraping strip 151 or the comb teeth 152, or can further include other cleaning structures, which are not limited here.

[0044] Please continue to refer to Figure 2 and Figure 5 In some embodiments, the water distribution member 130 is arranged along the axial extension of the rolling brush 120, and the cleaning member 150 is arranged along the axial extension of the rolling brush 120. The water distribution member 130 is provided with a rotating shaft 140 at each end in the length direction, and the torsion spring 160 is provided with two and is sleeved on the corresponding rotating shaft 140. Since the water distribution member 130 is provided with a rotating shaft 140 at each end, and each rotating shaft 140 is sleeved with a torsion spring 160, the rotation of the water distribution member 130 and the shell 110 is stable, the torsion force of the torsion spring 160 on the water distribution member 130 is evenly distributed, and the cleaning effect of the cleaning member 150 on the rolling brush 120 is better.

[0045] Further, the shell 110 is provided with a mounting cavity 111, and the mounting cavity 111 is arranged opposite to the rolling brush 120. The water distribution member 130 and the cleaning member 150 are arranged in rotation in the mounting cavity 111. The mounting cavity 111 can provide stable mounting and movement space for the water distribution member 130 and the cleaning member 150. The water distribution member 130 is provided with a first mounting hole 133 at each end in the length direction, and the two side cavity walls of the mounting cavity 111 are provided with a second mounting hole 112. One end of the rotating shaft 140 is inserted into the first mounting hole 133, and the other end is inserted into the second mounting hole 112. Since the two ends of the rotating shaft 140 are inserted into the water distribution member 130 and the shell 110, the rotating shaft 140 can be arranged separately from the water distribution member 130 and the shell 110, thereby facilitating the rotation and mounting of the water distribution member 130 on the shell 110, and facilitating the sleeving of the torsion spring 160 on the rotating shaft 140.

[0046] Among them, please continue to refer to Figure 5 and Figure 6 , Figure 6is a partial cross-sectional structural schematic diagram of an embodiment of the brush assembly of the present application. The abutting block 113 is arranged in the mounting cavity 111. The abutting block 113 is located between the second mounting hole 112 and the rolling brush 120. The water distribution member 130 includes a main body portion 131 and an extension portion 132. The extension portion 132 is located on the side of the main body portion 131 facing the rolling brush 120. The extension portion 132 protrudes from the main body portion 131 at both ends in the length direction. The main body portion 131 is used to interface with a clean water storage module in the cleaning device. The extension portion 132 is arranged to extend along the length direction of the rolling brush 120 and is used to open a plurality of water outlet holes to uniformly spray clean water on the rolling brush 120. The main body portion 131 is provided with a first mounting hole 133 on each side in the length direction. Since the extension portion 132 protrudes from the main body portion 131 at both ends, the main body portion 131 is recessed relative to the main body portion 131 at both ends, and the abutting block 113 can be at least partially located in the recess, at which time the first mounting hole 133 and the second mounting hole 112 are arranged opposite each other. When the torsional spring 160 is sleeved on the rotating shaft 140, the torsional spring 160 is axially limited between the housing 110 and the water distribution member 130, one end of the torsional spring 160 abuts against the side of the abutting block 113 away from the rolling brush 120, and the other end abuts against the side of the extension portion 132 away from the rolling brush 120.

[0047] The housing 110 and the water distribution member 130 are cooperatively designed, the water distribution member 130 and the torsional spring 160 can be compactly and rotatably mounted in the housing 110, and both ends of the torsional spring 160 can be stably supported on the housing 110 and the water distribution member 130, respectively, to stably realize storage and release of torsional force. The position of the torsional spring 160 is reasonable and relatively invisible, does not occupy other space in the housing 110, does not need to change the specifications and position layout of other parts, and does not greatly change and affect the space construction of the brush assembly 100.

[0048] When the cleaning member 150 cleans the hair on the surface of the rolling brush 120 that is difficult to clean, the cleaning member 150 may be entangled by the rolling brush 120 and driven to excessively rotate outward, causing the cleaning member 150 to be stuck with the rolling brush 120 and affecting the normal rotation of the rolling brush 120. Therefore, in order to limit the excessive rotation of the water distribution member 130 outward of the mounting cavity 111, i.e., toward the rolling brush 120, please continue to refer to Figure 6In some embodiments, the cleaning member 150 abuts against the bottom of the installation cavity 111 when the water diversion member 130 is turned outward to the predetermined angle. In the normal state, the cleaning member 150 does not abut against the bottom of the installation cavity 111, and the cleaning member 150 can maintain a stable extrusion force and an interference insertion amount with the roller brush 120 under the action of the torsional spring 160. When the water diversion member 130 is turned outward to the predetermined angle, the cleaning member 150 abuts against the bottom of the installation cavity 111, avoiding the cleaning member 150 from excessively approaching the roller brush 120 and interfering with the normal rotation of the roller brush 120. If the cleaning member 150 is entangled by the hair on the surface of the roller brush 120 at this time, the reaction force of the bottom of the installation cavity 111 on the cleaning member 150 can promote the cleaning member 150 to remove the hair on the surface of the roller brush 120, improving the cleaning effect of the cleaning member 150 in abnormal conditions.

[0049] In some embodiments, a limiting groove 1131 is formed in the lower part of the abutting block 113. When the lower end of the water diversion member 130 approaches the rotation of the roller brush 120, the upper end of the extension part 132 is reversed, and the limiting groove 1131 can provide space for the rotation of the extension part 132, making the installation of the water diversion member 130 in the installation cavity 111 more compact. In addition, when the water diversion member 130 is turned outward to the predetermined angle, the extension part 132 abuts against the inner wall of the limiting groove 1131. Similarly, in the normal state, the extension part 132 does not abut against the inner wall of the limiting groove 1131, and the cleaning member 150 can maintain a stable extrusion force and an interference insertion amount with the roller brush 120 under the action of the torsional spring 160. When the water diversion member 130 is turned outward to the predetermined angle, the extension part 132 does not abut against the inner wall of the limiting groove 1131, avoiding the cleaning member 150 from excessively approaching the roller brush 120 and interfering with the normal rotation of the roller brush 120.

[0050] It should be noted that within a reasonable range of variation of the diameter of the roller brush 120, the torsional spring 160 can drive the water diversion member 130 to rotate outward, and the water diversion member 130 is turned outward at an angle less than the predetermined angle, which can make the cleaning member 150 abut against the roller brush 120 and effectively clean the roller brush 120. When the water diversion member 130 is turned outward to the predetermined angle, although the water diversion member 130 cannot continue to rotate outward through the cooperation of the limiting structure described above, the cleaning member 150 can still achieve effective cleaning effect on the worn or collapsed roller brush 120.

[0051] In some embodiments, the shell 110 includes a floor brush base 114, and the floor brush base 114 is formed with a suction inlet 116. The floor brush base 114 is provided with the installation cavity 111, and the water diversion member 130 is rotationally arranged in the floor brush base 114. Generally, the roller brush 120 can be rotationally installed in the floor brush base 114, and the water diversion member 130 is rotationally arranged in the installation cavity 111 of the floor brush base 114, and the relative position relationship between the water diversion member 130 and the roller brush 120 is more reasonable and stable.

[0052] In some embodiments, the shell 110 comprises a brush base 114 and an upper cover 115 which is reversibly or detachably arranged on the brush base 114, and the water diversion member 130 is rotatably arranged on the upper cover 115, which is not limited herein.

[0053] Another embodiment of the present application provides a cleaning device (not shown in the figure). The cleaning device comprises the brush assembly 100 of any of the above embodiments. The cleaning device can be a robot vacuum cleaner, a floor washing machine or other cleaning devices. The brush assembly 100 cooperates with other modules of the cleaning device to achieve cleaning. Among them, the brush assembly 100 of the cleaning device of the present application has more stable and long-term effective cleaning performance.

[0054] Specifically, when the roller brush 120 in the brush assembly 100 is installed on the shell 110, the roller brush 120 will be extruded with the rotating member 101, so that the rotating member 101 will be rotated in a direction away from the roller brush 120, at this time the torsional spring 160 stores torsional force, and the cleaning member 150 can be elastically and rotatably floated relative to the roller brush 120. Under the action of the torsional force of the torsional spring 160, the cleaning member 150 is tightly attached to the roller brush 120, and the bristles of the roller brush 120 and the cleaning member 150 can maintain a certain extrusion force and a certain interference fit amount, thereby effectively scraping off the solid stains on the surface of the roller brush 120 and extruding the sewage in the roller brush 120. When the diameter of the roller brush 120 becomes smaller, the torsional force stored by the torsional spring 160 is released, and the rotating member 101 is driven to rotate close to the roller brush 120 until the cleaning member 150 is tightly attached to the roller brush 120. The cleaning member 150 can still maintain sufficient stable interference fit amount to the roller brush 120, maintain the extrusion effect and solid stain removal effect of the cleaning member 150 to the roller brush 120, reduce or even avoid the problems of insufficient contact between the cleaning member 150 and the roller brush 120, poor cleaning effect of the surface to be cleaned, increase of residual water on the surface to be cleaned, and reduction of the anti-winding ability of the roller brush 120, thereby prolonging the service life of the roller brush 120, ensuring the long-term stability of the product performance of the cleaning device, and improving the user experience.
