Description

[0001] The present invention relates to a filter for detachable protectors,

The present invention relates to a mask filter, and more particularly, to a filter for a dustproof or respiratory mask provided with a detachable protective member which is provided with a protective material for blocking foreign substances and detachably attached thereto for a long time.

The human body has built up a system of defense against harmful substances such as ciliates and mucous layers, but fine dust particles of very small size penetrate through the natural defenses of the human body and reach the lungs.

Inhalation of such dust for a long time will cause various lung diseases.

In modern medicine, however, there is no proper treatment for diseases caused by inhalation of dust, and once a disease occurs, it is difficult to recover healthy lungs again.

Therefore, it is generally considered to be a harmful substance such as paint / spray coating work, automobile manufacturing factory, chemical factory, pharmaceutical factory, nuclear power plant, petrochemical refinery, glass fiber processing factory, pesticide, ink, paint, Workers working in a high-volume environment should work with a dust-proof mask to filter out harmful substances from the respiratory tract.

The conventional dust-proofing mask has disadvantages that the entire dust-proofing mask must be disposed if the mask body and the dust-proofing filter performing the filtering function are formed integrally with each other and the life of the dust-

In order to solve this disadvantage, the dust-proof filter is separated from the mask body so that the dust-proof filter can be replaced only when the life of the dust-proof filter is shortened.

The structure of the dustproof filter that performs the purifying action of harmful substances in such a dustproof mask is basically composed of an activated carbon portion filled with activated carbon for decomposing and adsorbing harmful chemical substances and a nonwoven filter portion made of a nonwoven fabric bonded to the front and rear surfaces of the activated carbon portion have.

In the above structure, the harmful substances passing through the nonwoven fabric filter unit disposed on the front surface are decomposed and adsorbed in the activated carbon part, and again passed through the nonwoven fabric filter unit provided on the rear surface, and the harmful components are again sucked into the human body.

In general, the dustproof filter is replaced when the foreign matter is adhered to the surface of the nonwoven fabric filter portion and the inflow of air is impeded and the suction function of the user is impaired or the decomposition and absorption ability of the activated carbon portion is impaired.

On the other hand, in the case of coating operation during various operations carried out after wearing the dustproof mask, paint or dye particles which are not deposited on the solid matter by spraying are floated in the air, and these particles are usually deposited on the nonwoven fabric The filter is attached to the surface of the filter part, and the suction resistance of the air is increased due to these attachments, so that the user can replace the dust filter.

However, in the above case, since the activated carbon portion existing inside the dustproof filter still has the ability to decompose and adsorb foreign matter, the replacement of the dustproof filter itself causes not only a decrease in work efficiency but also a lot of losses &Lt; / RTI >
