Dust collector fullness indicator

Abstract

The invention discloses a dust collector fullness indicator for reminding a user about the vacuum degree in a dust-collecting cavity of a dust collector. The indicator comprises a front cavity, a rear cavity and a connector which is connected with the front cavity and the rear cavity and fixedly connected with the front cavity, and the rear cavity can slide relative to the connector and be fixed at the top end of the connector. The collector fullness /indicator provided by the invention divides the indicator into three parts; before being drawn, the indicator has small whole length, is convenient to mount a spring, avoids damaging the spring by overly drawing out the spring; and after the spring is mounted, the rear cavity is drawn and rotated to realize stable fixation and enable the spring to be in a drawing state. The dust collector fullness indicator provided by the invention has simple structure so that various elements in the indicator are easy to match, produce and mount, and the production efficiency of the dust collector fullness indicator is greatly improved.

Description

technical field [0001] The invention relates to the technical field of mechanical dust removal, in particular to a dust full indicator of a vacuum cleaner. Background technique [0002] Such as figure 1 As shown, a general vacuum cleaner 10 body includes a motor drive chamber 4 and a dust collection space 2 . The motor housing H with a fan (not shown) and a motor (not shown) that generates suction is installed in the above-mentioned motor drive chamber 4 . An exhaust member 9 is provided at the rear of the motor housing H to exhaust the air separated from the foreign matter to the outside of the vacuum cleaner 10 body. [0003] A suction inlet 1 is formed on the front side of the dust collection space 2 in front of the above-mentioned motor drive chamber 4, and a motor and a fan that can generate suction are provided between the dust collection space 2 and the exhaust member 9, so that the suction inlet 1 and The suction hose 6 connected to the suction inlet forms a sucti...

AI Technical Summary

Problems solved by technology

[0008] However, sometimes the elasticity of the elastic body 7s (such as a spring) of the dust-full indicator of the vacuum cleaner is not easy to control, and it is prone to lateral deviation, which causes the spring to be easily stuck and does not move, so that the indicator device 7d has poor dust-full display and cannot Move to the observation window in time, so that the indicator cannot correctly indicate the different vacuum degrees inside the vacuum cleaner, and the user cannot know the change of the amount of foreign matter such as dust collected by the dust bag 3 through the observation window

In addition, the dust full indicator of the vacuum cleaner contains too many moving elements, and there are also problems of difficult matching and complicated installation
