Problems solved by technology

[0010] The purpose of the present invention is to solve the problem that the filters in the prior art have insufficient suction rate due to too small and too dense filter holes, and if the filter holes are too thin and too large, the larger particles of dust will be directly discharged with the air, reducing the filtering effect.

Embodiment Construction

[0035] The invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0036] The double-layer filter structure for cyclone separation of the present invention comprises a square cylinder body 1 formed of a dome by the dust collection cylinder in an upright state, the bottom is provided with a dust collection bottom cover 2 of a corresponding shape, and the lower part of the partition plate 15 in the cylinder is a dust collection Space 3, where foreign matter such as dust to be cleaned is accumulated; the upper part of the partition 15 is formed with a cyclone separation space 4 with an air inlet 10 arranged along the tangential direction of the cylinder wall, and in the cyclone separation space 4, which is elliptical in cross section, horizontally placed conical shape, evenly distributed circular filter hole filter 5, conical cylindrical flat-top filter cover 14 evenly distributed filter holes 6, its bottom opening 7 and the con...

Abstract

The invention discloses a bi-layer filter structure for cyclone separation, belonging to dust separator of a dust collector. The bi-layer filter structure of the invention comprises a cone-shaped flattop filter cover evenly provided with filtration pores and a terminal pad which integrally forms a mesopore with the bottom opening thereof, and the other side of the terminal pad integrally forms anannular combination part combined with a motor cavity; the cone-shaped flat top filter cover evenly provided with filtration pores has a bi-layer structure keeping certain space. The invention with the design can change flow field distribution between two layers and can effectively reduce the flow of air which contains dust and enters a filter along tangential direction in cyclone separation space, thus distributing adsorbed air containing substances, such as dust and the like into each filtration pore as much as possible; as a result, dust has enough time to be separated out, thus improvingfiltering efficiency and keeping enough high adsorption rate.

Description

technical field [0001] The invention relates to a dust separator of a vacuum cleaner, in particular to a double-layer filter structure for cyclone separation. Background technique [0002] Vacuum cleaner is a kind of household appliance for indoor cleaning and sanitation, which is used to remove dust from floors, carpets, walls, furniture, clothing and various gaps. [0003] According to the shape of the vacuum cleaner, it can be divided into vertical vacuum cleaners, horizontal (tank) vacuum cleaners and portable vacuum cleaners. [0004] Generally speaking, the vacuum cleaner mainly includes a negative pressure suction generating device composed of a motor and a fan arranged in the body, which is composed of a suction head, a telescopic tube, a dust suction hose, and a suction pipeline connected to the air inlet of the body. When the vacuum cleaner is running, the motor drives the impeller of the fan to rotate at a high speed, exhausting the air inside the vacuum cleaner,...
