Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaners, in particular to a telescopic tube of a multifunctional vacuum cleaner. Background Art

[0002] A vacuum cleaner is a cleaning product that can be used in homes and workplaces. According to its structure, it can be divided into upright, horizontal and portable vacuum cleaners. The main reason for the vacuum cleaner to remove dust is that an electric blower is installed at its "head". There is an air impeller on the rotating shaft of the blower. After being powered on, the blower will rotate at a speed of 500 revolutions per second to generate a relatively high suction force and pressure. Under the action of the suction force and pressure, the air is discharged at high speed, generating a negative air pressure inside the sealed housing to suck in dust debris. Dust and other sundries pass through the carpet or floor brush and hose connector into the dust filter bag in sequence. The dust and other sundries are retained in the dust filter bag. After the air is purified by the filter element, it is discharged from the tail of the machine body. Generally, the power of a vacuum cleaner is 400 - 1000W or higher, and the power of a portable vacuum cleaner is generally 250W and below.
