[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 , Figure 2 and Figure 6 As shown, a self-cleaning dustpan comprises a dustpan body 1, a top cover 2 is fixedly connected to the top of the dustpan body 1, a plurality of comb teeth 3 are equidistantly arranged on the front of the top cover 2, a pulling assembly 4 is fixedly connected to both sides of the top cover 2, a cleaning plate 5 is sleeved on the plurality of comb teeth 3, both sides of the cleaning plate 5 are fixedly connected to the output end of the pulling assembly 4, the pulling assembly 4 is used to elastically pull the cleaning plate 5, tooth holes 6 are equidistantly arranged on the cleaning plate 5, and the comb teeth 3 are located inside the tooth holes 6. The cleaning plate 5 is sleeved on the comb teeth 3, and the pulling assembly 4 elastically pulls the cleaning plate 5. When it is necessary to clean the garbage adhered to the comb teeth 3, the cleaning plate 5 is pulled outward, and the cleaning plate 5 can remove the garbage on the comb teeth 3. Moreover, all parts are installed on the outside of the dustpan body 1, and there is no need to improve the existing one-piece dustpan body 1, so it is convenient to maintain and replace, which reduces the production cost and the repair cost, and improves the convenience of use.

[0026] like Figure 3 , Figure 4 Figure 5As shown, the pulling assembly 4 includes an outer frame 401, a moving plate 402 is slidably connected inside the outer frame 401, and a moving rod 403 is fixedly connected to one side of the moving plate 402; one end of the moving rod 403 penetrates and extends to the front of the outer frame 401, and one end of the moving rod 403 is fixedly connected to a connecting rod 404, and the connecting rod 404 is fixedly connected to the outer side of the cleaning plate 5. The upper and lower ends of one side of the moving plate 402 are fixedly connected to tension springs 405, and one end of the tension spring 405 away from the moving plate 402 is fixedly connected to the inner side wall of the outer frame 401. The other side of the moving plate 402 is rotatably connected to an L-shaped rod 406, and a clamping groove 407 is provided at the bottom of the outer frame 401, and one end of the L-shaped rod 406 is clamped inside the clamping groove 407. The L-shaped rod 406 is rotated upward and disengaged from the slot 407. The tension of the tension spring 405 pulls the movable plate 402, and the cleaning plate 5 is pushed through the movable plate 402 and the connecting rod 404. At this time, the cleaning plate 5 can automatically remove the garbage on the comb teeth 3, thereby improving the product performance and user experience.

[0027] like Figure 3 As shown, the outer side of the outer frame 401 is open, and the outer side of the outer frame 401 is fixedly connected with a side cover 408. The side of the side cover 408 is provided with a transverse groove 409 and a vertical groove 410. The vertical groove 410 is connected to one end of the transverse groove 409, and the bottom of the vertical groove 410 is connected to the clamping groove 407. The side cover 408 is fixed to the outer side of the outer frame 401, which is convenient for assembling and maintaining the parts in the outer frame 401; when the L-shaped rod 406 is rotated upward, the L-shaped rod 406 will enter the vertical groove 410 from the clamping groove 407, and enter the transverse groove 409 from the vertical groove 410. At this time, the tension of the tension spring 405 pulls the movable plate 402, and the L-shaped rod 406 will move in the transverse groove 409, and the moving length of the L-shaped rod 406 is limited, which is convenient for removing garbage on the comb teeth 3.

[0028] like Figure 1 and Figure 3 As shown, the length of the transverse groove 409 is equal to the length of the comb teeth 3. When the tension of the tension spring 405 pulls the movable plate 402, the L-shaped rod 406 moves in the transverse groove 409, and the transverse groove 409 can limit the length of the L-shaped rod 406. Since the length of the transverse groove 409 is equal to the length of the comb teeth 3, the head end of the comb teeth 3 can be flush with the front side of the cleaning plate 5 and will not be separated from the comb teeth 3.

[0029] like Figure 1 As shown, the dustpan bucket body 1 and the top cover 2 are fixedly connected with a joint 7, and a dustpan rod 8 is inserted into the inside of the joint 7. The movement and tilt of the dustpan bucket body 1 can be controlled by holding the dustpan rod 8, so as to realize the collection, transportation and dumping of sundries.

[0030] Working principle: When the comb teeth 3 are cleaned, the two L-shaped rods 406 arranged on the left and right are rotated upward at the same time, and the L-shaped rods 406 enter the vertical groove 410 from the card slot 407, and enter the horizontal groove 409 from the vertical groove 410. The tension of the tension spring 405 pulls the moving plate 402, and the cleaning plate 5 is pushed through the moving plate 402 and the connecting rod 404, and the cleaning plate 5 can remove the garbage on the comb teeth 3;

[0031] After cleaning, the two L-shaped rods 406 are pulled toward the rear end, and the cleaning plate 5 moves toward the tail end of the comb teeth 3. The L-shaped rod 406 slides backward in the horizontal groove 409. After the L-shaped rod 406 moves to the vertical groove 410, the L-shaped rod 406 is rotated downward, and the L-shaped rod 406 will pass through the vertical groove 410 into the card slot 407 to lock the L-shaped rod 406.

[0032] In summary, in the prior art, although the design on the dustpan body 1 is innovative and practical, there are still some problems and potential limitations. In the design and improvement process of this application, user needs and usage scenarios are fully considered, and all parts are installed on the outside of the dustpan body 1, and there is no need to improve the existing one-piece dustpan body, which is convenient for maintenance and replacement, reducing production costs and maintenance costs.
