Some specific embodiments of the vacuum cleaner 100 of the present utility model are described below. For convenience of description, the up-down direction of fig. 4 is a radial direction of the roller brush shaft 121, and the front-back direction of fig. 4 is an axial direction of the roller brush shaft 121. The cleaner 100 of the embodiment of the present utility model includes a frame 110, a roller brush 120, and a brush ring 130.

In some embodiments, as shown in fig. 1 to 5, the roller brush 120 includes a roller brush shaft 121 rotatably provided on the frame 110 and a cleaning brush 122 provided on an outer surface of the roller brush shaft 121, and the rotating roller brush shaft 121 may clean the floor by the cleaning brush 122 on an outer surface thereof. In the axial direction of the roller brush shaft 121, a gap is provided between the cleaning brush 122 and the frame 110.

In some embodiments, as shown in fig. 1-5, a brush ring 130 is provided on the frame 110 within the gap, the brush ring 130 cooperating with the cleaning brush 122. Specifically, as shown in fig. 4, the brush on the brush ring 130 may extend into the cleaning brush 122 in the front-rear direction, and when the cleaner 100 is in operation, impurities such as hair may pass through a gap between the cleaning brush 122 and the frame 110 and be wound around a transmission member between the roller brush 120 and the frame 110, and may be more likely to be caught on the transmission member to catch the roller brush 120. The brush ring 130 is positioned in the gap between the cleaning brush 122 and the housing 110 to block hair from passing through the gap between the cleaning brush 122 and the housing 110. In addition, hair may be entangled on the brush ring 130, thereby preventing hair from passing through the gap between the cleaning brush 122 and the frame 110.

Alternatively, the axis of the brush ring 130 is collinear with the axis of the roller brush shaft 121.

In some embodiments, as shown in fig. 1, 3, 4 and 5, the cleaner 100 further includes a shaft cover 140, the shaft cover 140 is disposed at an end of the roller brush shaft 121 and is located at an inner side of the frame 110, the shaft cover 140 is rotatably connected to the frame 110, the shaft cover 140 is provided with an annular groove 141 toward an end surface of the frame 110 in an axial direction of the roller brush shaft 121, the frame 110 is provided with a first annular protrusion 111, the brush ring 130 is disposed around the first annular protrusion 111, and at least a portion of the first annular protrusion 111 is fitted into the annular groove 141.

Specifically, by the cooperation between the first annular protrusion 111 and the annular groove 141, hair can be further blocked, and the rolling brush 120 is prevented from being blocked by Mao Faka on the transmission part, so that the service life of the dust collector 100 is prolonged.

Further, the brush ring 130 is disposed around the first annular protrusion 111, it is understood that the size of the brush ring 130 is larger than that of the first annular protrusion 111, and the brush ring 130 is located at the periphery of the first annular protrusion 111, i.e., there is a space between the inner surface of the brush ring 130 and the outer surface of the first annular protrusion 111.

In some embodiments, as shown in fig. 3 and 4, the roller brush shaft 121 is a cylindrical member, the shaft cover 140 is fitted over an end of the cylindrical member, and at least a portion of the shaft cover 140 is located within the cylindrical member.

In some embodiments, as shown in fig. 3 to 5, there is a first preset distance a between the first annular protrusion 111 and the groove bottom of the annular groove 141 in the axial direction of the roller brush shaft 121.

Specifically, the first annular protrusion 111 cooperates with the annular groove 141 to block hair, but it is inevitable that hair enters the space of the transmission member through a gap between the two. The first annular protrusion 111 and the groove bottom of the annular groove 141 have a first preset distance a therebetween, that is, the first annular protrusion 111 does not fully protrude into the bottom of the annular groove 141, and the space not protruding into the annular groove 141 can store hair.

In some embodiments, as shown in fig. 3 to 5, the shaft cover 140 is provided with a second annular protrusion 142 toward the end surface of the frame 110 in the axial direction of the roller brush shaft 121, the second annular protrusion 142 is disposed around the first annular protrusion 111, the brush ring 130 is disposed around the second annular protrusion 142, and a second preset distance b is provided between the inner surface of the second annular protrusion 142 and the outer surface of the first annular protrusion 111, the second preset distance b being greater than 0mm and less than 0.3mm.

Further, the second annular projection 142 is provided around the first annular projection 111, which can be understood as: the second annular projection 142 has a size larger than that of the first annular projection 111, and the second annular projection 142 is located at the periphery of the first annular projection 111, i.e., the inner surface of the second annular projection 142 and the outer surface of the first annular projection 111 have a space therebetween. Similarly, the principle of the brush ring 130 disposed around the second annular protrusion 142 is the same as that of the second annular protrusion 142 disposed around the first annular protrusion 111, and will not be described again. In addition, the second annular protrusion 142 is located between the first annular protrusion 111 and the brush ring 130.

Specifically, if hair is not caught by the brush ring 130, i.e., the hair passes through the gap between the cleaning brush 122 and the frame 110, the second annular protrusion 142 may act as a barrier for the hair, and may effectively block the hair from entering the reserved space between the first annular protrusion 111 and the annular groove 141. Further, a second preset distance b is provided between the inner surface of the second annular protrusion 142 and the outer surface of the first annular protrusion 111, the second preset distance b being greater than 0mm and less than 0.3mm. That is, the smaller the gap between the second annular projection 142 and the first annular projection 111, the less likely the hair will enter the gap between the second annular projection 142 and the first annular projection 111. That is, setting the distance between the second annular projection 142 and the first annular projection 111 can block hairs while ensuring mutual rotation between the second annular projection 142 and the first annular projection 111, avoiding friction therebetween.

In some embodiments, as shown in fig. 3 to 5, the second annular protrusion 142 has a third preset distance c between the radial direction of the roller brush shaft 121 and the frame 110, the third preset distance c being greater than 0mm and less than 0.3mm.

Specifically, the smaller the gap between the second annular projection 142 and the frame 110, the less likely hairs will enter the gap between the second annular projection 142 and the frame 110. That is, setting the distance between the second annular protrusion 142 and the frame 110 can block hairs while ensuring the mutual rotation between the second annular protrusion 142 and the frame 110, avoiding friction therebetween.

In some embodiments, as shown in fig. 3 to 5, the second annular protrusion 142 is provided with a third annular protrusion 143 on an outer surface thereof, the third annular protrusion 143 extends toward the brush ring 130, and a fourth preset distance d is provided between the outer surface of the third annular protrusion 143 and the inner surface of the brush ring 130, the fourth preset distance d being greater than 0mm and less than 0.3mm.

Specifically, during operation of the cleaner 100, hair may be entangled on the cleaning brush 122, and the hair on the cleaning brush 122 may pass over the brush ring 130 so that the hair may directly enter the gap between the cleaning brush 122 and the frame 110. A blocking barrier is formed between the third annular protrusion 143 and the brush ring 130, which can block the hair, and can effectively prevent the hair from crossing the brush ring 130.

In some embodiments, as shown in fig. 3 to 5, the third annular protrusion 143 has a fifth preset distance e between the frame 110 and the axial direction of the roller brush shaft 121, the fifth preset distance e being greater than 0mm and less than 0.3mm.

Specifically, the smaller the gap between the third annular projection 143 and the frame 110, the less likely the hair will enter the gap between the third annular projection 143 and the frame 110. That is, setting the distance between the third annular protrusion 143 and the frame 110 can block hairs while ensuring the mutual rotation between the third annular protrusion 143 and the frame 110, avoiding friction therebetween.

In some embodiments, as shown in fig. 1 and 2, the roller brush 120 is provided with at least two, one roller brush 120 being provided on one side of the frame 110, and the other roller brush 120 being provided on the other side of the frame 110.

In some embodiments, as shown in fig. 1 and 2, the cleaner 100 further includes a housing 150 and a driving assembly, the housing 150 is disposed on the frame 110, the driving assembly is disposed on the frame 110, and the driving assembly can drive the rolling brush 120 to rotate.
