Detailed ways

Embodiment: As shown in Fig. 1, the utility model provides a kind of vacuum cleaner with anti-mis-insertion cyclone, comprising a dust cup 10 with a cyclone chamber 102 and a dust collection chamber 100 arranged side by side, detachably from the bottom The cyclone 20 installed in the cyclone chamber 102 and the sealing ring 30 installed on the cyclone 20 . One side of the dust cup 10 also has a dust cup air outlet 104 communicating with the cyclone chamber 102 .

2-3, the cyclone 20 includes a grid-shaped air inlet 22 at one end, a base 24 at the other end, and a spiral guide portion 26 extending from the base 24 to the air inlet 22, wherein The base 24 includes a pair of opposite legs 246, an air outlet 240 between the two legs 246 and in the same air outlet direction as the dust cup air outlet 104, and first air outlets of different sizes arranged on its side walls. . Two locking elements (242, 244). Preferably, the first and second locking elements (242, 244) are respectively formed on the side walls of the base 24 at different heights. In this embodiment, the first and second locking elements (242, 244) are preferably protrusions , and the corresponding locking fit structure on the dust cup is a groove. A receiving groove 262 for receiving the sealing ring 30 is formed on a sidewall of the guiding portion 26 . The bottom of the legs 246 is provided with a rotating slot 248, the size of the rotating slot 248 can accommodate a single finger of the user, so the user can insert two fingers into the rotating slot 248, and then rotate it to complete the cyclone very conveniently. 20 installation/removal. At least one locking element ( 242 , 244 ) is formed on the outer sidewall of the leg 246 .

During use, the cyclone 20 enters the cyclone chamber 102 from the bottom of the cyclone chamber 102, and because the sizes of the first and second locking elements (242, 244) are different, the widths of the corresponding grooves on the dust cup are also different, Therefore, when it is wrongly inserted, because the two cannot match, the cyclone 20 cannot be rotated and installed in place, and the user can realize that the installation is wrong and needs to be adjusted before installing.

The utility model directly arranges the first and second locking elements with different sizes on the side wall of the cyclone, has a simple and convenient structure, and effectively prevents problems such as improper or wrong installation by users.

Of course, the above-mentioned embodiments are only to illustrate the technical conception and characteristics of the present invention, and its purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly, and not to limit the protection scope of the present invention. All equivalent changes or modifications made according to the spirit of the main technical solutions of the present invention shall fall within the protection scope of the present invention.
