[0022] As attached Figure 1 The image shows the brush device for a sweeper according to this utility model, including a detachably connected motor connector and a brush adjusting component. The motor connector includes a cover 1 and a motor connecting shaft 2. The cover 1 includes a top wall 11 and a side wall 12 surrounding the top wall 11. The motor connecting shaft 2 is connected to the center of the top wall 11 and extends away from the side wall 12. The side wall 12 of the cover 1 has an opening 13, and the inner side of the side wall 12 is machined with internal threads. (See attached image) Figure 3 As shown, the brush adjustment component includes a connecting truncated cone 3 and brush bristles 4. The brush bristles 4 are distributed in a ring at the bottom of the connecting truncated cone 3 to clean the road surface. An external thread 31 corresponding to the internal thread is machined on the circumferential surface of the connecting truncated cone 3. The motor connector and the brush adjustment component are connected by a cover 1 and the connecting truncated cone 3 via threads. By adjusting the engagement length between the motor connector and the brush adjustment component by different numbers of turns, the distance between the brush adjustment component and the ground can be changed. When the brush bristles 4 wear down after long-term use, simply screwing the brush adjustment component downwards will allow the brush bristles 4 to make full contact with the ground again, improving the road cleaning effect. This eliminates the need to replace the brush adjustment component, saving costs.

[0023] A sliding locking device is installed on the top of the connecting frustum 3. The sliding locking device includes a slider 521 and has a locked state and an open state. When in the locked state, as shown in the attached... Figure 1 Appendix Figure 2 As shown, the slider 521 extends through the opening 13 to the outside of the side wall 12 and is locked, preventing the motor connector and the brush adjustment component from rotating relative to each other. When in the open state, the slider 521 retracts to the inside of the cover 1, allowing the motor connector and the brush adjustment component to rotate relative to each other.

[0024] As attached Figure 3 Appendix Figure 4 As shown, the sliding locking device includes a mounting block 51, a sliding member, a fixing member 53, a spring 54, and a pin 55. The mounting block 51 and the fixing member 53 are fixedly connected to the connecting frustum 3. A horizontal groove is machined in the mounting block 51. The sliding member includes a connected slider 521 and a stop 522. The sliding member is slidably connected to the groove through the slider 521. The spring 54 is installed between the stop 522 and the fixing member 53. A locking hole 523 is machined on the slider 521. An insertion hole 32 is machined on the connecting frustum 3, extending from the bottom to the groove.

[0025] When in the locked state, as shown in the attached document Figure 3 As shown, the sliding member, under the pushing force of spring 54, causes one end of slider 521 to extend through opening 13 and be locked outside side wall 12, preventing the brush adjustment part from loosening during sweeper operation, thus avoiding affecting the cleaning effect or causing malfunction; when in the open state, as shown in the attached... Figure 4 As shown, the slider 521 can be pressed inward by hand or other tools to slide it inward until the locking hole 523 is coaxial with the insertion hole 32. The pin 55 is then inserted into the locking hole 523 through the insertion hole 32, keeping the slider 521 inside the cover 1 to prevent it from being pushed out by the spring 54. At this point, the brush adjustment component can be rotated to adjust it to a suitable position, and the slider 521 can be aligned with the opening 13 again. Then, the pin 55 can be pulled out, causing the slider 521 to pop out and fix the brush adjustment component again. When the bristles 4 are worn to a certain extent, the brush adjustment component can be completely removed and replaced with a new one, which is then connected to the motor connector to improve the cleaning effect.

[0026] In this embodiment, the side wall 12 has one opening 13, which extends axially along the side wall 12. After rotating the brush adjustment component, the slider 521 is inserted into different height positions of the same opening 13. In other embodiments, the side wall 12 has at least two openings 13, which are distributed around the side wall 12 or along the axial direction of the side wall 12, allowing for more precise adjustment of the brush adjustment component's height, enabling multiple adjustment levels to accommodate different brush bristle wear conditions.

[0027] As attached Figure 2As shown, the insertion hole 32 is away from the axis of the connecting frustum 3. A hexagonal boss 6 is formed at the center of the bottom of the connecting frustum 3, and a hexagonal groove 61 is machined at the center of the boss 6 to facilitate the insertion of tools, making the rotation of the brush adjustment component easier and more convenient.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
