Problems solved by technology

[0004] 1. The telescopic structure is relatively complicated, which increases the production cost;
[0005] 2. Due to the complex structure, it is very inconvenient to assemble and operate;
[0006] 3. Multi-stage expansion and contraction makes it difficult to seal between each section, and it is easy to seal failure;
[0007] 4. The telescopic positioning is unreliable. When there is abnormal suction, the telescopic section is easy to automatically retract

Abstract

The invention discloses a foldable floor brush, which comprises a main body part (21, 31), a folding part (22, 32) and a windshield device (23, 33), and a first air duct (201, 301) is arranged in the main body part The end of the main body is provided with a vent (203, 303) communicating with the first air passage; the folding part is pivotally mounted on the end of the main body, and a second air passage (202, 302) is arranged inside the folding part, The position of the second air duct close to the body part is provided with an opening corresponding to the vent; the windshield device moves with the folding part and has two working positions. In the first working position, when the folding part is unfolded in place relative to the main body, the windshield device is in the second working position of letting go of the ventilation opening. The width of the foldable floor brush of the present invention can be adjusted, and the wind-shielding device moves along with the folded part without separate operation, which is convenient and reliable.

Description

technical field [0001] The present invention relates to cleaning equipment, in particular to the structure of floor brushes which can be used in various occasions. Background technique [0002] With the improvement of people's living standards, people's requirements for the quality of life are getting higher and higher. People hope to live in a clean and tidy house. Therefore, floor brushes have been used more and more widely as a common cleaning equipment. At present, ordinary floor brushes are of fixed-size structure, and the width cannot change with the change of the cleaning area. Therefore, the application occasions of ordinary floor brushes are greatly limited, and inconvenience often occurs during use. [0003] The Chinese patent No. 200910307636.X discloses a multi-segment freely retractable floor brush. like figure 1 As shown, the floor brush 1 of this patent includes a symmetrical brush head body 11, an outer telescopic section 12, a middle telescopic section 13 ...
