HEPA self-cleaning vacuum cleaner

Abstract

The invention discloses an HEPA self-cleaning vacuum cleaner. The HEPA self-cleaning vacuum cleaner comprises: a dust collecting bucket, wherein an opening is formed on the top of the dust collectingbucket; a cover body which is connected to the top of the dust collecting bucket, wherein the cover body comprises a skirt portion and an end wall for closing the opening, the skirt portion is integrally connected with the end wall at an edge of the end wall and extends upward from the edge of the end wall, and ventilation holes for air inlet and outlet are formed in the end wall; and an HEPA assembly, wherein the HEPA assembly is arranged directly under the cover body, so that all the ventilation holes cover above the HEPA assembly. According to the invention, two air ducts and two motors areadopted, the HEPA is divided into two parts, and the two motors work at the same time, so that one half of the HEPA draws air forwardly to filter dust, and the other half of the HEPA can blow air backwardly to remove dust, and in this way, the synchronization of filtering and self-cleaning of the HEPA can be achieved, and the self-cleaning time of the HEPA can be greatly shortened.

Description

technical field [0001] The invention relates to the field of vacuum cleaners, in particular to a Hypa self-cleaning vacuum cleaner. Background technique [0002] The working principle of the vacuum cleaner is to use the motor to drive the blades to rotate at high speed, generate air negative pressure in the sealed shell, and absorb the surface of the carpet, floor, wall and other objects with dust, and the dust is sucked into the dust along with the air. After the separation component, the dust is filtered by the Hypa in the dust-air separation component and collected by the dust bucket, and the filtered clean air is discharged out of the vacuum cleaner body. [0003] After the Hypa has been working for a period of time, a large amount of dust is adsorbed on the surface of the dust collecting bucket. A large amount of dust adheres to the surface of the Hypa, which will block the tiny filter holes on the surface of the Hypa, thereby affecting the filtration of the Hypa. The ...

Problems solved by technology

[0003] After the Hypa has been working for a period of time, a large amount of dust is adsorbed on the surface of the dust collecting bucket. A large amount of dust adheres to the surface of the Hypa, which will block the tiny filter holes on the surface of the Hypa, thereby affecting the filtration of the Hypa. The current vacuum cleaners on the market have the following problems: On the one hand, the existing vacuum cleaners lack the function of self-cleaning the Hypa. Generally, after the Hypa is clogged, the Hypa will be slapped to remove debris after the machine is disassembled. , or directly replace the Hypa after disassembly, either way will take a lot of cleaning time, and the latter will directly lead to the replacement cost of consumables; on the other hand, even if the existing vacuum cleaner is equipped with Hypa self-cleaning function , also adopts the electromagnetic relay structure, that is, mechanically beats the hypa, so that the dust on the surface of the hypa shakes off into the dust collection bucket. More complex and costly to use
