[0041] Combine the following Figures 1 to 9 The utility model describes a disc brush, a cleaning component and a cleaning robot.

[0042] See also Figure 1 , which is a schematic diagram of a disc brush provided by an embodiment of the utility model. The disc brush 220 includes a disc brush body 221 and at least one blade 222. The disc brush body 221 has a first channel 223, and the first channel 223 runs through the disc brush body 221. The disc brush body 221 is configured to be rotatably arranged on the cleaning assembly 20; the blade 222 is arranged on the side wall of the disc brush body 221, and the blade 222 is arranged at an acute angle with the side wall, and the bottom of the blade 222 has bristles 224.

[0043] The disc brush 220 as a cleaning component can be arranged on the cleaning assembly 20 to perform cleaning operations, and the bristles on the disc brush 220 can be used to effectively clean the surface to be cleaned.

[0044] When the cleaning assembly 20 is cleaning the surface to be cleaned, the bristles 224 are in contact with the surface to be cleaned, and the disc brush body 221 is spaced from the surface to be cleaned, so that the garbage on the surface to be cleaned enters the cleaning assembly 20 through the first channel 223. The first channel 223 can be connected to a fan, and the fan sucks air through the first channel 223 to suck the garbage on the surface to be cleaned into the cleaning assembly 20.

[0045] The disc brush provided by the utility model is provided with at least one blade 222 on the side wall of a disc brush body 221 having a first channel 223, and the blade 222 is provided at an acute angle to the side wall of the disc brush body 221, and the disc brush body 221 is rotatably provided on the cleaning component 20. When the cleaning component 20 cleans the surface to be cleaned, the bristles 224 are in contact with the surface to be cleaned, and the disc brush body 221 is spaced apart from the surface to be cleaned, so that garbage on the surface to be cleaned can enter the cleaning component 20 through the first channel 223, and the blade 222 provided at an acute angle to the body 221 can play a role in cleaning and gathering garbage, and when the disc brush body 221 rotates, it drives the blade 222 to rotate, and the blade 222 repeatedly rubs the surface to be cleaned with the bristles 224. Compared with the form of a roller brush, the disc brush significantly improves the cleaning effect and cleaning efficiency.

[0046] Specifically, according to some embodiments of the utility model, the disc brush body 221 can be a cylindrical tube-shaped component with openings at both ends and a hollow structure, wherein the lower end opening is the inlet end of garbage (such as dust), and the upper end opening is the outlet end of the garbage. Under the action of the fan, negative pressure can be formed in the first channel 223 of the disc brush body 221. When the garbage is swept off the surface to be cleaned by the bristles 224 and reaches the vicinity of the inlet end of the first channel 223 under the convergence of the blades 222, the garbage can be sucked into the first channel 223 under the action of the negative pressure of the first channel 223 and introduced into the set position of the cleaning component 20 (such as the garbage bin 290 described below).

[0047] The blade 222 has a certain curved shape, one end of the blade 222 is connected to the side wall of the disc brush body 221, and the connection position of the blade 222 and the side wall of the disc brush body 221 is set at an acute angle. When cleaning, the disc brush 220 rotates, and the garbage is separated from the surface to be cleaned under the action of the bristles 224, and is gathered at the inlet end of the disc brush body 221 under the guidance of the inner wall of the blade 222.

[0048] According to some embodiments of the utility model, the blades 222 and the disc brush body 221 are integrally arranged to facilitate processing and manufacturing, improve the integrity and stability of the disc brush 220, and prevent the connection position between the blades 222 and the disc brush body 221 from emitting noise when the disc brush 220 rotates.

[0049] See also Figure 1As shown, according to some embodiments of the utility model, the blade 222 includes a plurality of blades 222, which are arranged at intervals on the side wall of the disc brush body 221, and the extension directions of the plurality of blades 222 from the side wall of the disc brush body 221 are consistent. By arranging a plurality of blades 222 with the same extension direction at intervals on the side wall of the disc brush body 221, during cleaning, the plurality of blades 222 can simultaneously clean the garbage attached to the surface to be cleaned, which can significantly improve the cleaning efficiency and cleaning effect, and the adjacent blades 222 can play a certain blocking role on the garbage, thereby improving the garbage gathering effect.

[0050] It should be noted that the above “the extension directions of the plurality of blades 222 from the side wall of the disc brush body 221 are consistent” specifically means that when each blade 222 is installed on the side wall of the disc brush body 221, the extension direction of the blade from the side wall remains the same and the opposite situation will not occur.

[0051] See also Figure 1 As shown, according to some embodiments of the utility model, the blade 222 has an arc, and the center point of the arc is close to the disc brush body 221. By setting the blade 222 as a blade 222 with a certain arc, and placing the center point of the arc close to the disc brush body 221, firstly, during cleaning, the blade 222 with a certain arc can gather dust and other garbage along the arc direction of the surface of the blade 222, and secondly, since the center of the arc is close to the disc brush body 221, the gathering position of the garbage is close to the disc brush body 221, which facilitates the garbage to enter the first channel 223 for collection and treatment.

[0052] It should be noted that the above “the center point of the arc is close to the disc brush body 221 ” specifically means that the blade 222 has a certain bending arc, and the center point of the arc refers to the geometric center of the arc, which is close to the disc brush body 221 .

[0053] According to some embodiments of the present invention, a guide notch may be provided at the inlet end of the disc brush body 221 to increase the opening area for garbage to enter the first channel 223 , which is beneficial for garbage to enter the first channel 223 .

[0054] The cleaning assembly 20 provided by the present invention is described below. The cleaning assembly 20 described below and the disc brush 220 described above can correspond to each other.

[0055] See also Figure 2 , Figure 3 Figure 6 and Figure 8As shown, the cleaning component 20 provided by the embodiment of the utility model includes a shell 210 and a plurality of disc brushes 220 as described in any of the above embodiments, the bottom of the shell 210 has an air duct 230, the air duct 230 includes a first groove 231 and a plurality of second channels 232; the plurality of disc brushes 220 are rotatably arranged in the first groove 231, the plurality of disc brushes 220 correspond one by one to the plurality of second channels 232, the first channel 223 of the disc brush 220 is connected to the second channel 232, and the second channel 232 is configured to be connected to the fan.

[0056] The cleaning assembly 20 provided by the utility model is provided with a plurality of the above-mentioned disc brushes 220 rotatably in the air duct 230 of the housing 210. When cleaning, the plurality of disc brushes 220 can sweep the garbage on the surface to be cleaned and gather in each first channel 223, and gather at the set position of the cleaning assembly 20 through the corresponding second channel 232 of the connected air fan, which significantly improves the cleaning effect and cleaning efficiency. In addition, the plurality of disc brushes 220 have a plurality of first channels, and the garbage near each disc brush 220 can enter the cleaning assembly 20 from the corresponding first channel, which can further increase the cleaning efficiency and effect.

[0057] See also Figure 4 As shown, according to some embodiments of the utility model, a plurality of disc brushes 220 are arranged in sequence, and the extension direction of the blade 222 of any disc brush 220 from the side wall of the corresponding disc brush body 221 is opposite to that of the adjacent disc brush 220. When the cleaning assembly 20 is working, the rotation direction of the disc brush 220 is the same as the extension direction of the blade 222. By sequentially arranging a plurality of disc brushes 220 in the first groove 231, the cleaning area of ​​the cleaning assembly 20 can be increased and the cleaning efficiency can be improved. At the same time, when the cleaning assembly 20 is working, the rotation direction of the disc brush 220 is the same as the extension direction of the blade 222, and the extension direction of the blade 222 of any disc brush 220 from the side wall of the disc brush body 221 is opposite to that of the adjacent disc brush 220, which can balance the force and effect generated when the adjacent disc brushes 220 rotate, thereby improving the stability of the cleaning assembly 20 when working and preventing the cleaning assembly 20 from positional displacement.

[0058] Specifically, see Figure 4 As shown, in this embodiment, the first groove 231 can be arranged along the length direction of the housing 210, and a plurality of disc brushes 220 are arranged in the first groove 231 at intervals along the length direction of the first groove 231. Preferably, the number of disc brushes 220 is set to an even number, which can further improve the stability of the cleaning assembly 20 when working.

[0059] See also Figures 4 to 7As shown, according to some embodiments of the present invention, the cleaning component 20 also includes a first driving motor 240 and a plurality of first driven gears 260, the driving end of the first driving motor 240 is provided with a first driving gear 250, and the first driving motor 240 is arranged on the shell 210; the plurality of first driven gears 260 correspond one-to-one to the plurality of disc brushes 220, and the plurality of first driven gears 260 are arranged on the disc brush body 221, adjacent first driven gears 260 are meshed with each other, and the first driving gear 250 is meshed with any first driven gear 260.

[0060] During cleaning, the driving end of the first driving motor 240 rotates, the first driving gear 250 rotates synchronously, and drives the first driven gear 260 meshing with the first driving gear 250 to rotate. Since adjacent first driven gears 260 mesh with each other, multiple first driven gears 260 can rotate synchronously and drive the disc brush body 221 to rotate, so that a single driving motor drives multiple disc brushes 220 to rotate synchronously. In addition, when driving each disc brush 220 to rotate, the above structure can also make the rotation directions of adjacent disc brushes 220 opposite. Combined with the above setting of the extension direction of the blades 222 on the adjacent disc brushes 220, the stability of the cleaning assembly 20 during operation can be improved.

[0061] See also Figures 5 to 8 As shown, according to some embodiments of the present invention, the shell 210 includes an upper shell 211 and a lower shell 212, a second channel 232 is formed at the bottom of the upper shell 211, and a first groove 231 is formed at the bottom of the lower shell 212. The bottom of the upper shell 211 is detachably connected to the top of the lower shell 212, and the lower shell 212 has a plurality of third channels 233 at positions corresponding to the plurality of second channels 232.

[0062] By providing the housing 210 with an upper housing 211 and a lower housing 212 that are detachably connected, it is convenient to disassemble the upper housing 211 and the lower housing 212 so as to install and arrange components such as the first drive motor 240, the first drive gear 250, and the first driven gear 260. At the same time, by providing the first drive motor 240, the first drive gear 250, the first driven gear 260 and other meshing components at the top of the lower housing 212, dust and other impurities generated during cleaning can be discharged to the set position of the cleaning component 20 through the first channel 223 and the second channel 232, preventing the above components from contacting with the generated dust and other impurities, thereby reducing the probability of failure of the driving components.
