Indirect combined structure of cyclone separation and dust collection devices

Abstract

The invention discloses an indirect combined structure of cyclone separation and dust collection devices and belongs to a dust separator of a dust collector. The indirect combined structure of the cyclone separation and dust collection devices comprises an oval cyclone cylinder, a tapered filter element, an air outlet, a dust outlet and an air inlet, wherein the tapered filter element is transversely arranged in the center of the oval cyclone cylinder, the air outlet is formed in the side portion of a closed end of the cyclone cylinder, the dust outlet is formed in the side portion of an open end of the cyclone cylinder, and the air outlet is formed in the inner cavity of the cyclone cylinder in the tangential direction. Moreover, the indirect combined structure is provided with a rotating shaft and a compression plate which are located in a dust collection cylinder and are in a transmission through an outer gear, and a wind path connecting piece which is fixedly connected with a dust collector body and guides dust from the dust outlet of the cyclone cylinder to the middle of a lower cover is arranged between the dust outlet of the cyclone cylinder and the lower cover of the dust collection cylinder. Due to the design, the cyclone cylinder and the dust collection cylinder are separated, and a wind path is communicated. Moreover, the indirect combined structure achieves that foreign matter such as dust separated in a cyclone mode falls into the dust collection cylinder in the central position of a dust collection cylinder cover, thus reduces the work load of a motor and the compression plate and ensures the excellence of products.

Description

Technical field [0001] The invention relates to a dust separator of a vacuum cleaner, in particular to an indirect combined structure of a cyclone separation and dust collection device. Background technique [0002] A vacuum cleaner is a cleaning and sanitary electrical device used to remove dust from floors, carpets, walls, furniture, clothing and various crevices. [0003] According to the classification of vacuum cleaners, they can be divided into vertical vacuum cleaners, horizontal (tank) vacuum cleaners and portable vacuum cleaners. [0004] The motor in the vacuum cleaner body drives the impeller of the fan to rotate at a high speed, expelling the air inside the vacuum cleaner, forming an instantaneous vacuum inside the vacuum cleaner, and forming a relatively high negative pressure difference with the outside atmosphere. Under the action of this negative pressure difference, foreign substances such as dust near the suction head or brush head together with air are sucked into...

AI Technical Summary

Problems solved by technology

[0014] The present invention aims to solve the problem that in the prior art, when the cyclone and the dust collection cylinder are directly combined, the falling dust and other foreign matter fall unevenly and are more concentrated on one side of the center of the dust collection cylinder, and provide a dust collector. Indirect combined structure of cyclone separation and dust collection device for uniform falling of different substances
