Vacuum cleaner

Abstract

The invention relates to a vacuum cleaner which comprises a floor brush, a dust collecting barrel 7 and a casing. The vacuum cleaner further comprises a telescopic hose 4, a telescopic mechanism and a clutch transmission mechanism. The clutch transmission mechanism controls the telescopic mechanism to extend out or retract; and the telescopic mechanism is connected with the telescopic hose 4 and drives the telescopic hose 4 to be stretched or retract. A telescopic dust collecting pipe is adopted, the length size of the vacuum cleaner is reduced, and the product is small in size and convenient to carry and accommodate; conventional manual adjustment of the length of the dust collecting pipe is abandoned, a motor is adopted to control the dust collecting pipe to be telescopic, the dust collecting pipe can be controlled in real time to extend or retract while dust collection operation is performed, so that the dust collecting operation is more flexible, and the vacuum cleaner is convenient to operate; a clutch device is adopted for assistance to control the dust collecting pipe to be telescopic, the adjustment of the dust collecting pipe is automatically stopped when the dust collecting pipe reaches a maximum length or a minimum length, manual control for stopping is not needed, and the damage to the mechanism caused by the problem that the telescopic mechanism goes on operating after reaching a stroke limit is avoided.

Description

technical field [0001] The invention relates to a vacuum cleaner, in particular to a hand-held vacuum cleaner. Background technique [0002] With the improvement of people's living standards, vacuum cleaners are widely used in household cleaning. The main components of vacuum cleaners are vacuum pumps, dust bags, hoses and nozzles of various shapes. There is an electric fan inside the machine, which runs at a high speed after being powered on, so that the inside of the vacuum cleaner forms an instant vacuum, and the internal air pressure is much lower than the outside air pressure. After being filtered by the filter, the dust remains in the dust collection bucket, and the purified air is discharged out of the vacuum cleaner through the motor, which plays the role of cooling the motor and purifying the air. [0003] Vacuum cleaners in the prior art are mainly divided into cylindrical vacuum cleaners and hand-held vacuum cleaners. Among them, hand-held vacuum cleaners are gr...

AI Technical Summary

Problems solved by technology

However, in the actual use of the vacuum cleaner, manual adjustment of the length of the telescopic tube and floor vacuuming cannot be carried out at the same time, and the length of the telescopic tube must be adjusted after the vacuum cleaner is stopped, which is very inconvenient to operate

In addition, the length of the telescopic tube of the vacuum cleaner can be adjusted at any time according to the needs of different environments during operation. Since the manual adjustment method cannot be carried out simultaneously with the dust collection operation, although the telescopic tube of the vacuum cleaner seems to be able to adjust the distance of the dust collection operation, the adjustment It is only carried out before the dust collection operation, and cannot be adjusted at any time during the dust collection operation, and it is impossible to truly adjust the dust collection operation distance
