[0065] In the following detailed disclosure, reference is made to the accompanying drawings and these embodiments are fully described. To make the technical solutions of the present invention clearer and more definite for those skilled in the art, the described implementation manners are not limited thereto. The present invention will be further described in detail below with reference to the embodiments and the accompanying drawings.

[0066] In the present invention, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance; the term "plurality" means two or more, unless otherwise clearly defined. Terms such as "mounting", "connecting", "coupling", "fixing", etc. should be understood in a broad sense. For example, "connecting" can be a fixed connection, a detachable connection, or an integral connection; "coupling" can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0067] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "front", "rear", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or unit referred to must have a specific direction, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0068] In the first aspect of the present utility model, as Figure 1 shown, a roller brush device is provided, which is applied to a cleaning device. The roller brush device includes a roller brush assembly 1, a transmission part 2, and a driving part 3. The roller brush assembly 1 at least includes a first roller brush 11 and a second roller brush 12; the transmission part 2 includes a first transmission mechanism 21 and a second transmission mechanism 22. The first transmission mechanism 21 is connected to the first roller brush 11, and the second transmission mechanism 22 is connected to the second roller brush 12; the driving part 3 drives the first transmission mechanism 21 and the second transmission mechanism 22 to drive the first roller brush 11 and the second roller brush 12 to rotate. The driving part 3 drives the second transmission mechanism 22 to drive the second roller brush 12 to rotate, and there is a rotational speed difference between the first roller brush 11 and the second roller brush 12.

[0069] In an embodiment of the second aspect of the present utility model, a cleaning device is provided. The cleaning device includes a device main body and a cleaning system. The cleaning system includes a roller brush device. The roller brush device includes a roller brush assembly 1. The roller brush assembly 1 is arranged below the device main body and can realize the cleaning treatment of dirt on the surface to be cleaned. The roller brush device can be a dry cleaning assembly.

[0070] In the prior art, the common roller brush is usually an integral body. When the roller brush interferes with linear objects such as hair, due to the characteristics of long length and soft material of the linear objects such as hair, the long and soft hair will spontaneously form many different configurations in the natural state. After being interfered by the roller brush, it is more likely to self-wind, and it is easy to wind around the roller brush and the rotating shaft of the roller brush. After long-term use, too much hair wound on the roller brush will cause the roller brush to deform, and it will also increase the loss of the roller brush driving part, reducing the service life of the cleaning device. After the hair detaches from the roller brush, it is easy to tangle into a ball and is not easily sucked into the air duct, affecting the cleaning efficiency. Therefore, it is necessary to regularly clean the hair on the roller brush manually, which is time-consuming and laborious.

[0071] In view of this, the present utility model provides a roller brush device. The roller brush device includes a roller brush assembly 1, a transmission part 2, and a driving part 3. The driving part 3 drives the first roller brush 11 to rotate through the first transmission mechanism 21, and the driving part 3 drives the second roller brush 12 to rotate through the second transmission mechanism 22. Among them, the rotational speeds of the two roller brushes are different.

[0072] It can be understood that the roller brush device includes at least two roller brushes. At least two roller brushes rotating at different speeds can cause the hair to be pulled between the roller brushes, preventing the hair from forming into clusters, enabling better inhalation into the air duct, improving the cleaning effect. The hair is easily broken under the pulling of the roller brushes, greatly reducing the situation of hair winding around the roller brushes, reducing the situation of the roller brushes being deformed due to hair winding, reducing the loss of the roller brush driving component, extending the service life of the cleaning device, reducing the frequency of manual cleaning of the hair on the roller brushes, and improving user satisfaction.

[0073] Among them, the number of roller brushes can be two, three, four or other quantities. The rotation speeds of adjacent two roller brushes are different, so as to achieve the pulling of the hair between the roller brushes rotating at different speeds. The material, size and number of the roller brushes can be set according to specific needs to meet different cleaning requirements.

[0074] It can be understood that the roller brush assembly 1 includes a first roller brush 11 and a second roller brush 12. The first roller brush 11 rotates at a first rotation speed, and the second roller brush 12 rotates at a second rotation speed. The first rotation speed and the second rotation speed are different, so that when the first roller brush 11 and the second roller brush 12 come into contact with the hair, due to the rotation speed difference between the two, the hair is stretched taut, difficult to form into clusters, difficult to wind around the roller brushes, and more easily inhaled into the air duct.

[0075] It can be understood that the hair is easily broken under the pulling of two roller brushes rotating at different speeds. After breaking, the length of the hair becomes shorter, not easily winding around the roller brushes, and more easily inhaled into the air duct.

[0076] In specific implementation, when the roller brush with a faster rotation speed first interferes with the linear object, and the roller brush with a slower rotation speed then interferes with the linear object, the linear object will be pulled between the two roller brushes, making the linear object more inclined to move towards the gap between the two roller brushes, not easily winding around the roller brushes, and more easily inhaled into the air duct; when the roller brush with a slower rotation speed first interferes with the linear object, and the roller brush with a faster rotation speed then interferes with the linear object, the linear object will be more fluffy between the two roller brushes, not easily winding around the roller brushes, and more easily inhaled into the air duct.

[0077] In an implementable manner, as Figure 1 shown, the roller brush device further includes a mounting bracket 4. The driving part 3 and the transmission part 2 are arranged on the mounting bracket 4, and the mounting bracket 4 is connected to the device main body of the cleaning device.

[0078] The roller brush assembly 1 is arranged on the device main body of the cleaning device through the mounting bracket 4. The roller brush assembly 1 that has a certain interference with the surface to be cleaned sweeps up the dirt on the ground and rolls it to the front of the suction port between the roller brush assembly 1 and the dust box, and then is inhaled into the air duct and enters the dust box to achieve dry cleaning.

[0079] As Figures 1 - 4As shown, the mounting bracket 4 may further include a connecting rod, which is connected to the device body through the connecting rod. An adaptive floating design can be adopted. Under the action of the self-weight of the roller brush device, the roller brush assembly 1 will swing freely downward, so that the roller brush assembly 1 can always contact the surface to be cleaned with a certain pressure. When the surface to be cleaned is uneven, the roller brush assembly 1 can always adhere to the ground and float along with the surface to be cleaned.

[0080] In an implementable embodiment, as Figure 2 shown, the first roller brush 11 and the second roller brush 12 can be coaxially arranged so that the first roller brush 11 and the second roller brush 12 can interfere with the same linear object to form a pulling force on the linear object.

[0081] In an implementable embodiment, as Figure 2 shown, interference or non-contact may occur between the first roller brush 11 and the second roller brush 12.

[0082] In this embodiment, taking the non-contact between the rotating first roller brush 11 and the rotating second roller brush 12 as an example, the linear object is tensioned or even broken under the pulling of the differential roller brush, and the differential roller brush is more likely to throw the linear object out and suck it into the air duct. The first roller brush 11 and the second roller brush 12 are separated from each other so that the linear object cannot be wound between the first roller brush 11 and the second roller brush 12, and a gap is formed between them. The first roller brush 11 and the second roller brush are in a small-gap fit, and the gap is located at the air inlet of the air duct to prevent air leakage caused by too large a gap. The small gap can ensure the gas flow rate between the first roller brush 11 and the second roller brush 12, making it easier for the linear object to be sucked into the air duct.

[0083] In an implementable embodiment, the ratio between the rotation speed of the first roller brush 11 and the rotation speed of the second roller brush 12 is 0.8 to 0.99.

[0084] It can be understood that there is a rotation speed difference between the first roller brush 11 and the second roller brush 12 to form a pulling force on the linear object during the contact with the linear object. In specific implementation, the driving part 3 drives the roller brush to rotate through the transmission part 2 to interfere with at least the impurities on the surface to be cleaned, and at the same time also interferes with the surface to be cleaned. If the rotation speed difference between the two is too large, the friction force between the roller brush and the surface to be cleaned is quite different, which will increase the load of the driving part 3. In view of this, the rotation speed difference between the first roller brush 11 and the second roller brush 12 can meet the requirement of forming a pulling force on linear objects such as hair, that is, the ratio between the rotation speed of the first roller brush 11 and the rotation speed of the second roller brush 12 can be 0.8 to 0.99.

[0085] In an implementable embodiment, as Figure 3 and 4As shown, the driving part 3 further includes a first driving member 31 and a transmission shaft 23. The output shaft of the first driving member 31 is power-connected to the first transmission mechanism 21, and the first transmission mechanism 21 is power-connected to the second transmission mechanism 22 through the transmission shaft 23; there is a difference in transmission ratio between the first transmission mechanism 21 and the second transmission mechanism 22.

[0086] In the above embodiment, when the first transmission mechanism 21 and the second transmission mechanism 22 share a driving member, the driving part 3 includes a first driving member 31 and a transmission shaft 23. The first transmission mechanism 21 and the second transmission mechanism 22 are power-connected through the transmission shaft 23 and driven by the first driving member 31. That is, the output shaft of the first driving member 31 is power-connected to the first transmission mechanism 21 to drive the first rotary brush 11 to rotate, and the first transmission mechanism 21 is power-connected to the second transmission mechanism 22 through the transmission shaft 23 to drive the second rotary brush 12 to rotate. Since the transmission ratios of the first transmission mechanism 21 and the second transmission mechanism 22 are different, the rotation speeds of the first rotary brush 11 and the second rotary brush 12 are different. Through the arrangement of the transmission shaft 23, the function of driving two rotary brushes to rotate at different speeds by one driving member can be achieved, reducing the power module, simplifying the structure, having a small space occupancy rate, and reducing the cost.

[0087] In an implementable manner, as Figures 5 - 7 shown, the first transmission mechanism 21 includes a first gear set 211. The first gear set 211 includes a first output end and a second output end. The first output end is power-connected to the first rotary brush 11, and the second output end is power-connected to the transmission shaft 23; the second transmission mechanism 22 includes a second gear set 221. The transmission shaft 23 is power-connected to the second gear set 221, and the output end of the second gear set 221 is power-connected to the second rotary brush 12.

[0088] As Figure 5 shown, the output shaft of the first driving member 31 is power-connected to the first gear set 211. The first output end of the first gear set 211 is connected to the first rotary brush 11 to drive the first rotary brush 11 to rotate, and the second output end of the first gear set 211 is connected to the transmission shaft 23 to drive the transmission shaft 23 to rotate; as Figure 6 and 7 shown, the transmission shaft 23 is power-connected to the second gear set 221, and the output end of the second gear set 221 is connected to the second rotary brush 12 to drive the second rotary brush 12 to rotate. The transmission difference is realized through the different structures of the first gear set 211 and the second gear set 221, and the transmission ratio difference can be adjusted through the specific design of the gear structure, quantity, and number of teeth.

[0089] In an implementable manner, as Figure 8As shown, the first gear set 211 includes a first gear 2111, a second gear 2112, and a third gear 2113. The first gear 2111 is connected to the output shaft of the first driving member 31; the first gear 2111 is in power connection with the second gear 2112. The second gear 2112 is the first output end and is coaxially arranged with the first brush 11; the first gear 2111 or the second gear 2112 is in power connection with the third gear 2113. The third gear 2113 is the second output end and is connected to the transmission shaft 23.

[0090] In the above embodiment, when the first transmission mechanism 21 and the second transmission mechanism 22 share one driving member, the first gear set 211 includes a first gear 2111 connected to the output shaft of the first driving member 31. The first gear 2111 is in power connection with the first output end. The first gear 2111 or the first output end is in power connection with the second output end. Between the first gear 2111 and the first output end, between the first gear 2111 and the second output end, and between the first output end and the second output end, other gears that meet the requirements can also be set according to the power requirements.

[0091] Among them, as Figure 8 shown, the first gear set 211 may further include a fourth gear 2114 and a fifth gear 2115. The fourth gear 2114 is arranged between the first gear 2111 and the second gear 2112 and meshes with the first gear 2111 and the second gear 2112; the fifth gear 2115 is arranged between the first gear 2111 and the third gear 2113 and meshes with the first gear 2111 and the third gear 2113; or, the fifth gear 2115 is arranged between the second gear 2112 and the third gear 2113 and meshes with the second gear 2112 and the third gear 2113.

[0092] Among them, the first output end of the first gear set 211 is the second gear 2112. A fourth gear 2114 and / or a fifth gear 2115 may be meshed between the first gear 2111 and the second gear 2112 for transmission; the second output end of the first gear set 211 is the third gear 2113. A sixth gear 2116 may be meshed between the first gear 2111 and the third gear 2113 or between the second gear 2112 and the third gear 2113 for transmission. The fourth gear 2114, the fifth gear 2115, and the sixth gear 2116 are not limited to one gear and may also be multiple gears, achieving the function of transmission between the driving part 3, the first output end, and the second output end.

[0093] In an implementable manner, as Figure 9As shown, the second gear set 221 includes a seventh gear 2211 and an eighth gear 2212. The seventh gear 2211 is connected to the transmission shaft 23. The seventh gear 2211 is power-connected to the eighth gear 2212. The eighth gear 2212 is the third output end and is connected to the second brush 12. The eighth gear 2212 is coaxially arranged with the second brush 12.

[0094] In the above embodiment, when the first transmission mechanism 21 and the second transmission mechanism 22 share a driving member, the second gear set 221 includes a seventh gear 2211 connected to the transmission shaft 23. There is a power connection between the seventh gear 2211 and the output end of the second gear set 221. Other gears that meet the requirements can also be arranged between the seventh gear 2211 and the output end according to the power requirements.

[0095] Among them, as Figure 9 shown, the second gear set 221 may further include a ninth gear 2213. The ninth gear 2213 is arranged between the seventh gear 2211 and the eighth gear 2212 and meshes with the seventh gear 2211 and the eighth gear 2212.

[0096] Among them, the output end of the second gear set 221 is the eighth gear 2212. A ninth gear 2213 may be meshed between the seventh gear 2211 and the eighth gear 2212 for transmission. The ninth gear 2213 is not limited to one gear and may also be multiple gears, achieving the function of transmission between the transmission shaft 23 and the output end of the second gear set 221.

[0097] In an implementable manner, as Figure 10 shown, the driving part 3 further includes a first driving member 31 and a second driving member 32. The output shaft of the first driving member 31 is power-connected to the first transmission mechanism 21. The output shaft of the second driving member 32 is power-connected to the second transmission mechanism 22.

[0098] In the above embodiment, when the first transmission mechanism 21 and the second transmission mechanism 22 do not share a driving member, the driving part 3 includes a first driving member 31 and a second driving member 32. The first driving member 31 drives the first brush 11 to rotate through the first transmission mechanism 21. The second driving member 32 drives the second brush 12 to rotate through the second transmission mechanism 22.

[0099] It can be understood that there is an output speed difference between the first driving member 31 and the second driving member 32; and / or there is a transmission ratio difference between the first transmission mechanism 21 and the second transmission mechanism 22, achieving the function of forming a speed difference between the first brush 11 and the second brush 12.
