[0002] With the continuous development of technology, cleaning equipment has widely entered families, significantly improving the convenience of life. As a key component, the design of the cleaning brush is directly related to the cleaning effect and user experience. Traditional cleaning brushes are usually used in various scenarios, such as kitchens, toilets, cars, etc.

[0003] However, currently, the cleaning brushes for cleaning dust and impurities in gaps often do not have a structure inside to prevent dust and impurities from adhering to the brush head.

[0034] Please refer to Figure 1 - Figure 14 The present invention provides a technical solution: a cleaning brush with a self-cleaning mechanism, including a lower shell 1, a base 2 is fixedly installed at the bottom of the lower shell 1, a rubber pad 3 is fixedly installed at the bottom of the base 2, a charging port 4 is arranged on the base 2, a push-button switch 5 is arranged on the lower shell 1, an upper shell 6 is fixedly installed at the top of the lower shell 1, anti-slip protrusions 7 are arranged on the outer side of the lower shell 1, a main board 8 is fixedly installed inside the base 2, a battery holder 9 is clamped inside the lower shell 1, a battery body 10 is clamped inside the battery holder 9, the push-button switch 5, the main board 8 and the battery body 10 are electrically connected. In addition, an elastic rod 131 is fixedly installed on the outer side of the battery holder 9, an upper block 132 and a lower block 133 are respectively arranged at both ends of the elastic rod 131, and both the upper block 132 and the lower block 133 are clamped inside the side wall of the lower shell 1. In addition, two groups of the elastic rod 131, the upper block 132 and the lower block 133 are provided, so that the disassembly and assembly of the cleaning brush body are more convenient.

[0035] In an embodiment of the present utility model, a vibration assembly 11 is provided on the lower shell 1. The vibration assembly 11 includes a motor 111. The motor 111 is fixedly installed inside the lower shell 1. A rotating shaft 112 is fixedly installed at the output end of the motor 111. When the motor 111 is started, the rotating shaft 112 rotates. A frustum 113 is fixedly installed at the top of the rotating shaft 112. An eccentric wheel 114 is fixedly installed at a position away from the center of the top of the frustum 113. Thus, the eccentric wheel 114 is driven to rotate in cooperation with the frustum 113. A limiting block 115 is fixedly installed inside the upper shell 6. A clamping ring 116 is rotatably installed on the limiting block 115. A swing block 117 is fixedly installed on the outer side of the clamping ring 116. There are two groups of swing blocks 117. The eccentric wheel 114 is located between the two groups of swing blocks 117. A circular plate 118 is attached to the outer side of the top of the upper shell 6. The limiting block 115 and the clamping ring 116 cooperate to make the swing block 117 swing reciprocally. At the same time, the clamping ring 116 rotates reciprocally. A clamping post 119 is fixedly installed at one end of the circular plate 118. The clamping post 119 is clamped inside the upper shell 6. In addition, there are four groups of clamping posts 119, and the four groups of clamping posts 119 are equally spaced in a circumferential array with the center of the cross-sectional circle of the circular plate 118 as the array center, so that the circular plate 118 is more stable. A brush head 1110 is attached to the outer side of the other end of the circular plate 118. A brush hair is provided on the outer side of one end of the brush head 1110. A clamping block 1111 is fixedly installed on the outer side of the other end of the brush head 1110. A clamping groove 1112 is formed on the clamping ring 116. The clamping block 1111 is clamped inside the clamping groove 1112. A short post 1113 is fixedly installed on the outer side of the clamping block 1111. The short post 1113 penetrates through the clamping ring 116. By cooperating with the circular plate 118, the clamping post 119, the clamping block 1111, the clamping groove 1112 and the short post 1113, the brush head 1110 can be clamped on the clamping ring 116, so that the brush head 1110 can achieve a vibrating effect. Thus, compared with the traditional stationary cleaning brush body, the cleaning effect is better. At the same time, the vibrating effect makes it difficult for dust to adhere to the brush hair of the brush head 1110, so that the brush head 1110 can be self-cleaned. An auxiliary groove 1114 is formed on the circular plate 118, which facilitates disassembly and assembly in cooperation with the auxiliary groove 1114.

[0036] In an embodiment of the present utility model, a heat dissipation component 12 is provided on the upper shell 6. The heat dissipation component 12 includes a fan blade 121, and the fan blade 121 is fixedly installed outside the rotating shaft 112. A heat dissipation groove 122 is formed on the upper shell 6. A thin shaft 123 is rotatably installed inside the side wall of the upper shell 6. The outside of the thin shaft 123 is fixedly installed inside the center of the heat dissipation plate 124. Further, when the rotating shaft 112 rotates, it drives the fan blade 121 to rotate synchronously, thereby generating an air flow blowing towards the heat dissipation groove 122. Note that there is a damping force between the heat dissipation plate 124 and the inner wall of the upper shell 6, and it will not be blown by the above-mentioned air flow. A push rod 125 is fixedly installed outside the heat dissipation plate 124, and the heat dissipation plate 124 fits inside the heat dissipation groove 122. In addition, a conical cover 126 is snap-fitted inside the heat dissipation plate 124, and a filter plate 127 is snap-fitted inside the conical cover 126. There are multiple groups of the conical cover 126 and the filter plate 127, and the multiple groups of the conical cover 126 and the filter plate 127 are linearly arrayed at equal intervals, so that the heat dissipation and protection effects are better. It is worth noting that the air flow generated by the fan blade 121 is blocked by the conical cover 126 and the filter plate 127, and is not sufficient to blow up the swept dust, etc., avoiding dust flying. Holding the push rod 125 and cooperating with the thin shaft 123 enables the heat dissipation plate 124 to rotate, so as to dissipate heat better through the conical cover 126 and the filter plate 127. At the same time, when the cleaning brush body is not in use, the filter plate 127 faces towards the inside of the upper shell 6, so that the smaller end of the circular cross-section of the conical cover 126 faces the outside, so as to effectively prevent external dust from entering the inside of the cleaning brush body, and thus can better protect the cleaning brush body.

[0037] Working principle: When the motor 111 is started, the rotating shaft 112 rotates, and thus cooperates with the frustum 113 to drive the eccentric wheel 114 to rotate. Cooperating with the limit block 115 and the snap ring 116, the swing block 117 swings reciprocally. At the same time, the snap ring 116 rotates reciprocally. And cooperating with the circular plate 118, the clamping column 119, the clamping block 1111, the clamping groove 1112 and the short column 1113, the brush head 1110 can be snap-fitted on the snap ring 116, so that the brush head 1110 can achieve a vibrating effect. Thus, compared with the traditional static cleaning brush body, the cleaning effect is better. At the same time, the vibrating effect makes the dust not easily adhere to the bristles of the brush head 1110, so that the brush head 1110 can be self-cleaned. Cooperating with the auxiliary groove 1114 is convenient for disassembly and assembly. Further, when the rotating shaft 112 rotates, it drives the fan blade 121 to rotate synchronously, thereby generating an air flow blowing towards the heat dissipation groove 122. Note that there is a damping force between the heat dissipation plate 124 and the inner wall of the upper shell 6, and it will not be blown by the above-mentioned air flow. Holding the push rod 125 and cooperating with the thin shaft 123 enables the heat dissipation plate 124 to rotate, so as to dissipate heat better through the conical cover 126 and the filter plate 127. At the same time, when the cleaning brush body is not in use, the filter plate 127 faces towards the inside of the upper shell 6, so that the smaller end of the circular cross-section of the conical cover 126 faces the outside, so as to effectively prevent external dust from entering the inside of the cleaning brush body, and thus can better protect the cleaning brush body.

[0038] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made to it, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit of the present utility model are within the protection scope of the present utility model.
