Problems solved by technology

[0012] Both hands are needed to realize the folding, which is inconvenient for special users. After folding, there is no constraint on the lower extension tube. When in use, the lower extension tube is easy to return automatically. Once it returns, it needs to be folded again, causing unnecessary trouble

Embodiment Construction

[0027] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0028] The operating principle of the vacuum cleaner of the present invention is the same as the prior art, and can refer to the prior art, so it will not be described again. The differences between the present invention and the prior art will be described in detail below:

[0029] like image 3 As shown, the vacuum cleaner folding tube structure of the present invention includes: an extension tube, which is divided into a lower extension tube 520 and an upper extension tube 530 ; Connecting parts 521 and 531 are provided on the lower extension pipe 520 and the upper extension pipe 530, respectively. The connecting portion 531 includes a through hole formed at the tail end of the upper extension tube 530 and cylindrical rotating bodies 532 disposed on both sides of the through hole. The connection part 521 includes a detachment prevention piec...

Abstract

The invention discloses a folding tube structure of a dust collector, which comprises an extension tube, a pair of joint rotating parts and an upper sleeve and also comprises a switch restraining mechanism, wherein the extension tube is divided into a lower extension tube and an upper extension tube; a clamp is formed on the cylinder of the upper sleeve; and clamping slots are symmetrically formed on the peripheries of the two side covers of the joint rotating parts. The folding tube structure of the dust collector of the invention has the advantages that: the structure is simple; multi-angle folding of the lower extension tube can be realized by one hand; different use requirements are met; a folded state is stable; and the phenomenon of automatic return is avoided.

Description

technical field [0001] The invention relates to a vacuum cleaner, in particular to a folded tube structure of the vacuum cleaner. Background technique [0002] Vacuum cleaner is a kind of household appliance for indoor cleaning and sanitation, which is used to remove dust from floors, carpets, walls, furniture, clothing and various gaps. [0003] figure 1 It is a perspective view of a prior art vacuum cleaner. like figure 1 As shown, it includes: a fuselage 100 ; a suction pipeline connected to the suction side of the fuselage 100 . A fan and a dust collection unit 400 are provided inside the body 100 to send clean air to the outside after filtering out foreign objects in the air. [0004] The suction line is a line for sucking in air and foreign matter using the suction force of the body 100 . Specifically, the suction pipeline includes: a suction nozzle 1 that uses a strong air flow to inhale air containing foreign matter from the outside; The end operation handle 3;...
