Problems solved by technology

Usually, in order to achieve the best sealing effect and stability, the pressure in the assembly direction is often high, which is not convenient for assembly, especially for the filter mechanism, which needs to be disassembled frequently, the inconvenience of assembly makes it easier for users to worry about the overall quality of the product. The experience becomes worse; in addition, the soft seal tends to lose its elasticity after being subjected to strong pressure, and its sealing effect tends to deteriorate after repeated disassembly

Abstract

The invention discloses a dust collector. The dust collector comprises a machine body, a negative pressure component arranged in the machine body, a dust separation component arranged on the upstreamside of the negative pressure unit and a dust collection component matched with the dust separation component, wherein the dust separation component at least comprises a filtering unit detachably installed in the machine body; a sealing washer is arranged between the filtering unit and the machine body; the sealing washer at least comprises a flexible main body part fixedly connected with one of the machine body or the filtering unit, and a first lip side part extending from the flexible main body part to the other one of the machine body or the filtering unit; an included angle between the first lip side part and the main body part is an acute angle, and the opening of the included angle faces the upstream side of the filtering unit, so that the sealing effect between the filtering unit and the machine body is enhanced, and the sealing stability is enhanced.

Description

technical field [0001] The invention relates to a filtering and sealing structure of a vacuum cleaner. Background technique [0002] In the prior art, soft seals on the upper and lower sides are generally used for the sealing and fixing of the filter mechanism, and the sealing between the filter mechanism and the machine head or the fuselage is realized through the crimping and fixing formed in the assembly direction of the filter mechanism. seal. Its sealing effect depends on the pressing force in the assembly direction. Usually, in order to achieve the best sealing effect and stability, the pressure in the assembly direction is often high, which is not convenient for assembly, especially for the filter mechanism, which needs to be disassembled frequently, the inconvenience of assembly makes it easier for users to worry about the overall quality of the product. The experience becomes worse; in addition, the soft seal tends to lose its elasticity after being subjected to s...
