[0022] The utility model is now further described with reference to the accompanying drawings.

[0023] like Figures 1 to 10As shown, a dustpan with comb teeth 51 for automatic cleaning comprises comb teeth 51, handle 1, dustpan body 4, drive seat 2, telescopic seat 52, extension spring and cover plate 3. The top of dustpan body 4 is provided with telescopic slot 43, tooth hole 42 and drive hole 44, the tooth hole 42 is arranged in array and communicates with the telescopic slot 43, the drive hole 44 is located at the rear of dustpan body 4 and on the center line of dustpan body 4, and anti-slip grooves 47 are symmetrically arranged on both sides of drive hole 44. The top of drive seat 2 is connected with handle 1, the bottom of drive seat 2 is provided with drive slot 20, and anti-slip hooks 22 are symmetrically arranged on both sides of drive slot 20, the drive seat 2 is movably inserted in the drive hole 44, and the anti-slip hook 22 is movably inserted in the anti-slip groove 47, and the anti-slip hook 22 can be stuck at the bottom of the anti-slip groove 47 to limit the drive seat 2 to rise and fall in the drive hole 44. The comb teeth 51 are arranged on the telescopic seat 52, and the comb teeth 51 and the telescopic seat 52 are an integral structure. The telescopic seat 52 is slidably inserted in the telescopic groove 43, and the comb teeth 51 are movably inserted in the tooth hole 42. A telescopic push block 54 is provided at the center of the end of the telescopic seat 52 away from the comb teeth 51. The telescopic push block 54 is movably inserted in the driving hole 44 and the driving groove 20 of the driving seat 2, and a lower pushing inclined surface 55 is provided on the telescopic push block 54. The lower pushing inclined surface 55 is arranged opposite to the top of the driving groove 20, and is used to push the telescopic seat 52 to move so that the comb teeth 51 retract to the rear of the tooth hole 42; the two ends of the extension spring respectively abut on the telescopic push block 54 and the driving hole 44, so as to keep the comb teeth 51 in a state of extending out of the tooth hole 42; the cover plate 3 is installed on the top of the dustpan body 4 and is located at the top of the telescopic groove 43.

[0024] In the free state, the telescopic seat 52 abuts against the side of the telescopic slot 43 under the action of the extension spring, the comb teeth 51 extend out of the tooth holes 42, the lower push slope 55 lifts the drive seat 2 through the drive slot 20, and the anti-drop hook 22 is stuck on the anti-drop slot 47.
