Dedusting device of vacuum cleaner

Abstract

The dedusting device of vacuum cleaner includes one first cyclonic dedusting unit to separate foreign matter from air sucked through the first suction port and dedust the air; one outflow unit located inside the first cyclonic dedusting unit and possessing side through holes communicated to the first air exhaust port of the first cyclonic dedusting unit; and one side guide wall connected to the first cyclonic dedusting unit to guide the air flowing into the first sucking port to the tangent direction of the inner wall in the first cyclonic dedusting unit and to avoid the direct flow of the sucked air to the outflow unit. The present invention has raised dedusting performance.

Description

technical field [0001] The invention relates to a dust removal device of a vacuum cleaner, in particular to a dust removal device of a vacuum cleaner which utilizes the principle of a cyclone to absorb foreign matter. Background technique [0002] The cyclone dust removal device is a device that uses the principle of a cyclone to remove dust and other foreign matter contained in the air. Cyclone dust removal devices are suitable for use in various fields, among which they are suitable for use in vacuum cleaners in the domestic field. [0003] Recently, in order to improve the dust removal performance of the cyclone dust collector, a multi-cyclone dust collector having a plurality of cyclone parts is used. [0004] Below, please refer to figure 1 As shown, the dust removal device of the vacuum cleaner in the prior art is described as follows. [0005] The existing dust removal device is characterized in that it includes: the first cyclone dust removal part 10, which can re...

Problems solved by technology

[0011] But, in the air that flows into the first suction port 11 of the above-mentioned first time cyclone part 13 on the existing dust removal device as mentioned above, a part does not circle along the inner wall of the above-mentioned first time cyclone part 13, but directly flows into the above-mentioned first time. The center of the secondary cyclone part 13, so the foreign matter contained in the air flowing into the first suction port 11 is directly discharged from the first discharge port 12 without separation, and there is a problem of reducing dust removal performance.

[0012] This shows that above-mentioned existing dedusting device obviously still has inconvenience and defect in structure and use, and urgently needs to be further improved

In order to solve the problems of the dust removal device, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general products do not have a suitable structure to solve the above problems. This is obviously a problem. Issues that relevant industry players are eager to solve
