Embodiment
As shown in Figure 1 to Figure 3, the utility model discloses a kind of mask filter mechanism, including mask body and strainer group
Part, the net-filter assembly include strainer cover, strainer and strainer bottom cover, and the strainer is installed on the strainer cover and the filter
Between net bottom lid, the strainer section is zigzag, and it is in pleated structure that it is overall, and the mask body is equipped with air intake duct, described
The inlet end of air intake duct is equipped with strainer mounting groove, and the net-filter assembly is installed in the strainer mounting groove and detachably to connect
Connect, strainer is pleated structure, its section into zigzag, can so increase strainer with entering the contact area of air, make its mistake
It is more preferable to filter effect, and the volume of mask can be reduced while air inflow is ensured, and the mask filter mechanism and mask
Body is detachably connected, and can be convenient for changing strainer.
Further, the filtering net surface is covered with Elastic buckle, and the mask body is equipped with fixed card slot, the filtering net surface
Lid is stuck in the fixed card slot, is fixedly connected, and dismounting is simpler.
The strainer bottom cover side opposite with the strainer cover is additionally provided with sealing ring, ensures sealing effect, so that really
Protect filter effect.
The filtering net surface is covered with multiple bar shaped air admission holes, ensures air inlet effect.
The utility model is simple in structure, strainer is pleated structure, its section into zigzag, can so increase strainer with into
Enter the contact area of air, make its filter effect more preferable, and the volume of mask can be reduced while air inflow is ensured, and
And the mask filter mechanism is detachably connected with mask body, can be convenient for changing strainer.
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that the specific implementation of the utility model is confined to these explanations.For the ordinary skill of the utility model technical field
For personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should all be regarded
To belong to the scope of protection of the utility model.
