The switch component 3 further includes a limiting structure 38 for limiting the button board 32 and the key board 31 to move in the central axis direction of the button board 32, the limiting structure 38 includes a first limiting surface 381 and a second limiting surface 382 arranged opposite to the first limiting surface 381, the first limiting surface 381 is arranged on the key board mounting seat 33, when the contact 342 and the pressing portion 341 are separated, the first limiting surface 381 supports against the second limiting surface 382, when the contact 342 and the pressing portion 341 are contacted, the first limiting surface 381 and the second limiting surface 382 are far away from and form a distance, and the distance is equal to the second distance.

Specifically, the button plate 31 is sleeved in the button plate 32, the button plate 32 has a hook portion 323, the hook portion 323 extends from two sides of the button plate 32 toward the direction of the button plate 31 to form, the second limiting surface 382 is disposed on the hook portion 323 of the button plate 32, the base 111 extends upward to form two baffles 35, the two baffles 35 are disposed on two sides of the button plate 32 respectively, an insertion groove 39 is formed between the baffle 35 and the hook portion 323, the button plate mounting seat 33 is annular, and the annular button plate mounting seat 33 is sleeved in the insertion groove 39 to abut against the hook portion 323. In other embodiments, the keypad mounting seat 33 and the keypad 31 may be integrally formed, and are not limited in particular. By sleeving the key sheet 31 in the button sheet 32, on one hand, the key sheet 31 is prevented from shifting when contacting the button sheet 32, and on the other hand, the overall structure is compact.

Referring to fig. 4, in order to ensure that the first roller 1121 and the second roller 1122 can contact with the contact surface to facilitate the movement of the vacuum cleaner 100, the cleaning member 12 is made of an elastic material with good water absorption and compressibility, specifically, the cleaning member 12 may be made of a material such as collodion or fiber, and is not limited thereto.

The above description is only for the purpose of illustrating embodiments of the present invention and is not intended to limit the scope of the present invention, and all modifications, equivalents, and equivalent structures or equivalent processes that can be used directly or indirectly in other related fields of technology shall be encompassed by the present invention.
