Connecting structure for ground brush and bend of dust collector

Abstract

The invention discloses a connecting structure for a ground brush and a bend of a dust collector. The two opposite sides of a connector of the bend are respectively provided with a first protruding part, movable space is formed in the shell in the mode of corresponding to the first protruding parts, the first protruding parts slide back and forth in the movable space, the two opposite sides of the shell are further respectively provided with a second protruding part, a third protruding part and a torsional spring, one end of each torsional spring is connected to the corresponding first protruding part, the other end of each torsional spring is connected to the corresponding third protruding part, and the second protruding parts are sleeved with spring rings. By means of the connecting structure; on the premise that the ground brush and the bend have the excellent sealing performance, the flexible rotating performance can be kept, and the whole using performance of the dust collector is accordingly improved.

Description

technical field [0001] The invention relates to the field of vacuum cleaners, in particular to a connection structure between a brush and an elbow of a vacuum cleaner. Background technique [0002] Vacuum cleaner is a kind of cleaning equipment widely used in people's life, whether it is the cleaning of household places or commercial or service industry places, it is inseparable from its use. With the advancement of technology and the continuous improvement of living standards, people's requirements for the performance of vacuum cleaners are also gradually increasing, which also prompts vacuum cleaners to be in an environment of continuous innovation and improvement. [0003] In the composition of the vacuum cleaner, the elbow and the ground brush are two of its more important accessories. In the current vacuum cleaner, since the ground brush is a kind of movable part, and it is set to rotate flexibly with the elbow, thus there will be a large gap between the ground brush a...

AI Technical Summary

Problems solved by technology

Although these means have enhanced the sealing performance of the connection between the elbow and the ground brush, they have increased the friction area between the elbow and the ground brush, thereby increasing the resistance suffered when the elbow rotates, and the elbow And the activities of the floor brush are hindered, causing inconvenience to the use of the vacuum cleaner
