This utility model discloses an air purification mechanism for a ventilation device, including a ventilation housing. The air inlet end of the ventilation housing is connected to an air inlet duct via a flange, and the air outlet end of the ventilation housing is connected to an exhaust duct via a flange. A fan is installed inside the exhaust duct. A mesh protective plate is screwed onto one end of both the air inlet and exhaust ducts. This utility model improves air purification efficiency by sequentially arranging a filter screen, an electrostatic dust collection module, a HEPA filter element, and an activated carbon layer within the ventilation housing. The layered spatial arrangement allows for periodic disassembly, cleaning, or replacement of the filter screen. A self-cleaning structure is provided above the filter screen. A nylon brush moves parallel to the filter screen surface via a synchronous belt, and the negative pressure suction port enhances the cleaning effect. When the differential pressure sensors at both ends detect that the filter screen resistance reaches a preset value, cleaning is triggered, achieving self-cleaning of the filter screen, shortening cleaning time, and improving the filter screen flux recovery rate.

This utility model discloses a polymer composite toothbrush head in the field of daily necessities, including a toothbrush head connected to a toothbrush handle. A toothbrush base is provided at the front end of the toothbrush head, and an mounting groove is formed on the upper side of the toothbrush base. The mounting groove includes an upper groove and a lower groove, with the area of ​​the upper groove being smaller than that of the lower groove. A toothbrush plate is installed correspondingly within the mounting groove, and multiple bristle bundles are provided on the toothbrush plate. A cover is provided at the front end of the toothbrush base corresponding to the toothbrush plate. A rinsing groove is formed inside the toothbrush head, and multiple rinsing holes are formed through the toothbrush plate. Each rinsing hole is staggered from each bristle bundle, and each rinsing hole corresponds to the rinsing groove. This utility model avoids the need to directly replace the toothbrush, saves more raw materials, and allows for regular cleaning of the bristle gaps, keeping the toothbrush clean.
