AI Technical Summary
The primary filter section of existing combined air purifier units is prone to clogging and has poor sealing, resulting in inconvenient cleaning and poor sealing performance.
The design incorporates an inclined filter screen and blocking block structure, combined with a vibrating filter plate design, to reduce impurity adhesion; the air valve uses an external gear structure with toothed plates and gears to improve sealing.
This allows for convenient cleaning of the filter and improves the device's sealing, thereby enhancing the filtration efficiency and sealing effect of the air purification unit.
