Self-cleaning dust collecting barrel of dust collector

Abstract

The invention discloses a self-cleaning dust collecting barrel of a dust collector. The dust collecting barrel comprises a dust collecting cabin (1); a rotary shaft (2) is arranged in the centre of the bottom of the dust collecting cabin (1); a longitudinally distributed compression piece (3) is fixedly arranged on an outer side wall of an upper part of the rotary shaft (2); the rotary shaft (2) has a hollow structure; an airflow inlet (31) is formed on the bottom of the rotary shaft (2); at least one airflow outlet (32) is formed on an outer edge of the compression piece (3); an air channel is formed in the compression piece (3), corresponds to the airflow outlet (32) and is communicated with the airflow inlet (31) and the air flow outlet (32) on the bottom of the rotary shaft (2); and the airflow inlet (31) is communicated with airflow outside the dust collecting barrel. The self-cleaning dust collecting barrel can effectively solve the problem that dust is easily adsorbed on an inner wall of the dust collecting cabin, clean the inner wall of the dust collecting cabin by the airflow timely, save electric energy and allow a user to observe the dust collecting condition in the dust collecting cabin through the wall body.

Description

technical field [0001] The invention relates to the technical field of mechanical dust removal, in particular to a dust collecting barrel of a self-cleaning vacuum cleaner. Background technique [0002] Generally, a vacuum cleaner is a device that uses a vacuum to generate suction to inhale air, make the air flow through various filters, filter foreign objects in the air, and clean the room. [0003] Generally speaking, a vacuum cleaner mainly includes a suction device and a suction pipeline. The suction device mainly formed by a motor and a fan is arranged in the body. The suction pipeline includes a suction head and a suction pipe. The suction head has a downward opening. The suction port communicates with the air inlet of the fan inside the body through the telescopic pipe and the flexible pipe of the suction pipe. When the vacuum cleaner is running, the motor drives the impeller of the fan to rotate at a high speed, exhausting the air in the vacuum cleaner, forming an i...

Problems solved by technology

[0009] In view of this, the purpose of the present invention is to provide a self-cleaning vacuum cleaner dust collection bucket, which can effectively solve the problem that the inner wall of the dust collection bin is easy to absorb dust, and clean the inner wall of the dust collection bin in time through the airflow, thereby reducing the cost of rotating the compression piece. Electric energy reduces the daily use cost of the vacuum cleaner user, and allows the vacuum cleaner user to observe the dust collection inside the dust collection bin through the wall, dump the dust in time, and prolong the service life of the vacuum cleaner, which has great practical significance in production
