Abstract

The utility model relates to a wet mask for preventing SARS, which comprises two parts: a mask and a virus filtering box, wherein, air inlets and air outlets are all arranged on the mask and the virus filtering box; the air inlet of the mask is connected with the air outlet of the virus filtering box. An upright partition board by which the inner cavity of the box is divided into a front and a rear chambers is arranged in the virus filtering box; the upright partition board is adjacent to a rear wall of the box and is connected with a top cover of the upright partition board and a left and a right box walls; a gap exists between the upright partition board and the bottom of the box; the rear chamber of the box is communicated with the air inlet of the box; a sponge filtering layer with disinfecting liquid is arranged in the front chamber of the box. A unidirectional film valve is respectively arranged on the air outlet of the mask and the air outlet of the virus filtering box. The air inlet of the virus filtering box is arranged on the rear wall of the box; the air outlet is arranged on the top cover of the box; eye rings are arranged on the mask and the virus filtering box. The edge of the mask is spongy cylindrical shape. The utility model has the characteristics that the wet mask has scientific design, reasonable structure, small volume, light weight and convenient operation, the wet mask can filter and kill virus and purify air, and can effectively prevent virus from being sucked in.

Description

Wet type prevention of atypical pneumonia mouth mask

(1) technical field

The utility model relates to a kind of mouth mask, particularly a kind of wet type prevention of atypical pneumonia mouth mask.

(2) background technology

Traditional mouth mask prevents that for people a large amount of suctions of dust, assurance people's healthy tool from having certain effect, but because the sieve aperture of gauze is too big, be difficult to stop the intrusion of virus, for example be difficult to stop the intrusion of novel coronavirus, it is exactly a proof that a lot of medical personnel are infected by novel coronavirus.And the number of plies that unrestrictedly increases the mouth mask gauze also is unpractical.

(3) summary of the invention

At the deficiencies in the prior art, the utility model provide a kind of design science, rational in infrastructure, volume is little, in light weight, easy to use, can filtering and kill virus, purify air, effectively prevent the wet type prevention of atypical pneumonia mouth mask that virus is inhaled into.

A kind of wet type prevention of atypical pneumonia mouth mask comprises mouth mask and viral filtering box two parts, all is provided with air inlet and gas outlet on mouth mask and the viral filtering box, and the air inlet of mouth mask is connected with the gas outlet of viral filtering box; Be provided with in the virus filtering box one the box inner chamber is divided into before and after the vertical clapboard of two Room, this vertical clapboard is connected near the box rear wall and with the top cover and the left right box wall of viral filtering box, and a gap is arranged between at the bottom of the box; The chamber is communicated with the air inlet of box behind the box, is provided with the sponge filtering layer of a band thimerosal in the box cup.

The air inlet of virus filtering box is located on the rear wall of box, and the gas outlet is located on the top cover of box.

Respectively be provided with a unidirectional film flap valve on mouth mask gas outlet and the viral filtering box gas outlet.

All be provided with earrings on mouth mask and the viral filtering box.

The mouth mask edge is soft cylindrical.

When people use this mouth mask, air is entered the back chamber of viral filtering box by the air inlet of viral filtering box, then enter the cup of box by the bottom of vertical clapboard and viral filtering box, then by the sponge filtering layer of band thimerosal and the unidirectional film flap valve on the viral filtering box gas outlet in the cup, sucked by human body, airborne virus is through the absorption of sponge filtering layer and killing of thimerosal, and what make that human body sucks is the air that has been cleaned, thereby has prevented viral infection.The utlity model has design science, rational in infrastructure, volume is little, in light weight, easy to use, can filtering and kill virus, purify air, effectively prevent the characteristics that virus is inhaled into.
