Cyclone filter device and dust collector

Abstract

The invention discloses a cyclone filter device and a dust collector. The cyclone filter device comprises a dust collecting cup, a HEPA (high efficiency particle air) filter, a lower cover, an upper cover, an air guiding plate and an air stopping plate, wherein the dust collecting cup is provided with an air inlet; the HEPA filter is arranged in the dust collecting cup; the lower cover closes thetail end of the HEPA filter; the upper cover is arranged at the peripheral edge of the upper end of the HEPA filter; the air guiding plate is arranged between the inner wall of the dust collecting cupand the HEPA filter; the tail end of the air guiding plate extends towards the inner wall of the dust collecting cup relative to an initiating end of the air guiding plate, so that centrifugal forceis generated when cyclone carrying dust rotates along the air guiding plate to separate dust from the cyclone; the air stopping plate is arranged on one side of the air inlet to guide the cyclone carrying the dust to the air guiding plate from the air inlet; and the initiating end of the air guiding plate is connected with the air stopping plate. The cyclone filter device is simple in structure, by addition of the air stopping plate and the air guiding plate, the centrifugal force is generated by air to separate the dust so as to reduce the number of dust sucked in the HEPA filter, the dust separating and filtering effect is improved, and the service life of the HEPA filter is prolonged.

Description

technical field [0001] The invention relates to the field of cleaning appliances, in particular to a cyclone filter device and a vacuum cleaner. Background technique [0002] The main part of the existing Hypa filter is the Hypa filter structure. The Hypa filter structure is mainly made of superfine fiber as the filter material and high-quality kraft paper is formed by hot rolling. Its shape is mainly a ring structure with several folds. , the filter effect is achieved through these pleated structures during use. Therefore, the Hypa filter is often used in the cyclone filter device of the vacuum cleaner. For example, the existing bagless vacuum cleaner uses the high-speed cyclone formed by the rotation of air in the dust box made of metal shell to separate the dust gas. The dust is concentrated and compressed to the designated position, and then the air is filtered by the Hypa filter. , to achieve the purpose of dust removal. However, a large amount of dust in the dust co...

Problems solved by technology

However, a large amount of dust in the dust collection box flows into the Hypa filter together with the air, causing the Hypa filter to absorb a large amount of dust in a short time, causing the Hypa filter to be easily blocked, which not only affects the service life of the Hypa filter, but also reduces Improves the effect of the Hypa filter to separate and filter dust
