Compressing device of dust collecting barrel and control method thereof

Abstract

The invention discloses a compressing device of a dust collecting barrel. The dust collecting barrel comprises a separation cavity, a dust collecting cavity and a separation board, wherein the separation board is fixedly connected with the bottom of the separation cavity, and a gap is formed between the separation board and the inner wall of the dust collecting barrel; an inner dust collecting barrel is arranged in the dust collecting barrel and can hermetically slide up and down relative to the dust collecting barrel; and a through hole is formed at the bottom of the dust collecting barrel, a convex nozzle capable of being hermetically connected with the through hole is arranged on a mounting table of the dust collecting barrel, and the convex nozzle is selectively communicated with an air suction part or an air exhaust part of a motor cavity through a pipeline by using a valve. The invention further discloses a control method of the compressing device, when a dust collector is started, a dust falling hole is opened and the convex nozzle is controlled to be communicated with the air suction part; and when dust collection is completed by a user, the dust falling hole is closed and the convex nozzle is controlled to be communicated with the air exhaust part, and the inner dust collecting barrel moves upwards to compress dust. According to the invention, a compression motor is unnecessary to use, so that the dust collecting cavity can be used for accommodating more dust, electric energy is saved, and the dust is easy to pour out and the reliability is high.

Description

Technical field [0001] The present invention relates to the technical field of mechanical dust removal, in particular to a compression structure of a dust collecting bucket of a novel vacuum cleaner with dust compression function. Background technique [0002] Generally, a vacuum cleaner is a device that uses vacuum to generate suction to inhale air, flow the air through various filters, filter foreign matter in the air, and clean the room. [0003] Generally speaking, a vacuum cleaner mainly includes a suction device and a suction pipe. The suction device mainly formed by a motor and a fan is arranged in the body. The suction pipe 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 in the machine body through the telescopic tube and the hose of the suction pipe. When the vacuum cleaner is running, the motor drives the impeller of the fan to rotate at a high speed, expelling the air in the ...

AI Technical Summary

Problems solved by technology

[0007] The above-mentioned compression piece of the dust bin in the dust collection bucket of the vacuum cleaner needs to be driven by a stepping motor, and the dust is rotated and compressed in the forward and reverse directions by controlling the stepping motor, so that the above-mentioned compression piece 3 pushes the dust to a fixed position. The unilateral compression near the compression plate 100 is easy to form a dead corner of dust near the fixed compression plate 100, and it is impossible to compact all the dust, which affects the cleaning of the dust in the dust collection bin 1; The power consumption of the vacuum cleaner is relatively large, which greatly increases the daily use cost of the vacuum cleaner user and seriously reduces the user's experience in using the product.
