Description

Technical Field

[0001] This utility model relates to a HEPA sealing structure and a vacuum cleaner having the HEPA sealing structure, belonging to the technical field of household cleaning products. Background Technology

[0002] HEPA filters are a key component in vacuum cleaners. During operation, they capture fine particulate matter in the air, effectively reducing allergens and pollutants in indoor air. The mounting points of the HEPA filter in vacuum cleaner products need to be sealed. Current technology requires balancing airflow resistance and filtration efficiency in HEPA sealing. An overly tight seal, while preventing leakage, may increase airflow resistance and affect suction power; an insufficient seal, on the other hand, leads to decreased filtration efficiency and secondary pollution.

A first EVA sealing ring is provided at the top of the motor cover to seal between the top of the motor cover and the HEPA frame. A second EVA sealing ring is provided at the bottom of the motor cover to seal between the bottom of the motor cover and the HEPA frame. A third EVA sealing ring is provided at the end of the dust cup near the cyclone cone cover to seal between the dust cup and the cyclone cone cover. A fourth EVA sealing ring is provided at the end of the cyclone cone near the cyclone cone cover to seal between the cyclone cone and the cyclone cone cover. An air guide channel is provided in the HEPA frame, and the air guide channel is located within the space enclosed by the first, second, third, and fourth EVA sealing rings.

[0005] Preferably, the motor cover is provided with a groove for installing the second EVA sealing ring.

[0006] Preferably, the motor cover is provided with an inverted buckle, and the HEPA frame is provided with a fastening groove, so that the inverted buckle is fastened into the fastening groove when the motor cover and the HEPA frame are installed.

[0007] Preferably, the HEPA frame is provided with a handle.

[0008] Preferably, the airflow channel is streamlined.

[0009] This utility model also provides a vacuum cleaner having the above-mentioned HEPA sealing structure, wherein the vacuum cleaner includes the above-mentioned HEPA sealing structure.

[0010] The beneficial effects of this utility model are: the HEPA sealing structure of this utility model makes the flow channel and the HEPA installation part well sealed, balances the HEPA sealing and the suction power of the vacuum cleaner, and ensures the sealing of the flow channel and the HEPA installation part while meeting the appropriate suction power of the vacuum cleaner.
