Detailed description about embodiment：
The sheet type filter cartridge 1 of above example can be thickness it is uniform, shape be circle 10, ellipse, flat rectangle, it is U-shaped,
It can be with the abnormal shape of the bending of facial application of a surface.
1 shell of sheet type filter cartridge of above example is plastic material, point upper and lower two panels before assembling, wherein a piece of or two
There are one on pieces or the space support structure of multiple columns or facade, after internal component group installs, by described between two panels
Column or facade structures are connected with ultrasonic welding.
The preparation of filter cartridge：Sheet-like filter box shell includes A, B two panels, selects independent injection molding, material that can select
Select PE, ABS etc., there is the structures such as column and facade on the inside of contact filtration material, by meshed filter material be fixed on edge and
Make with ultrasonic welding that A, B two panels pass through column and facade links into an integrated entity and incites somebody to action after gas outlet specific position, between two panels
Meshed filter material is fixed on filter cartridge particular position inside, and meshed filter material can breathe freely and obstruct granular activated carbon,
By carburizing hole, filter cartridge assembling can be completed in local ultrasound welding again again after the carburizing hole filling activated carbon stayed in advance.
Sheet-like filter box is that the activated carbon in snoot formula breathing mask canister is laid in human body face, and gas is from sheet
Edge enters, and keeps the gas of sucking human body also longer than snoot formula filter by the path (effectively filtering distance) of activated carbon,
Filter effect does not subtract, but wears more comfortable.
Sealing structure with face is ripe technology, such as the rubber face mask of snoot formula breathing mask, by oral cavity and
Nose is all covered in the cavity that it is formed with filtering tank, and sealing is connect by the mushroom-shaped button on canister between canister；
