Bucket type face mask

Abstract

The invention discloses a barreled mask, comprising a tubbiness body, a cover, an inlet channel (port), a filter element, an air inlet valve, an air passage (for transporting the filtered gas), a mask, an exhaust valve (or an exhaust valve cover, or an exhaust passage) and a lacing, which is characterized in that: the tubbiness body is arranged below the nozzle (or front of the nozzle, or paralleled with the wire splice of both ears), the inner filter element of the tubbiness body is connected with the air inlet valve, the air inlet valve is connected with the air passage, the air passage is connected with the mask (or the filter element is connected with the air inlet valve air passage, the air passage is connected with the air inlet valve, the air inlet valve air inlet valve mask; or the filter element is connected with the tubbiness body), or a sealing gasket is arranged between the connections; the air passage is connected (or a whole) with the tubbiness body (or the mask, or the air inlet valve); the cover is connected with the tubbiness body (or the filter element); the mask is connected as a whole with the tubbiness body (or is connected) which is arranged on the casing between both ends (or in the middle) of the tubbiness body (or can move towards one end or both ends) to be connected (or contacted) with human face, to cover oronasal (or face, or head); a lace (or the exhaust valve, or the exhaust cover, or the exhaust passage, or the air inlet valve) is arranged on the mask (or the tubbiness body). The barreled mask has the advantages of lager filter area, more comfortable respiratory than the public compound mask.

Description

Technical field [0001] The invention relates to a barrel-shaped mask, especially a mask and a barrel-shaped main body. There is a barrel-shaped main body under the mask. The barrel-shaped main body is placed horizontally under the mouth (or in front of the mouth). The shaped main body has an intake valve and an air delivery channel, and is connected with a mask, so the breathing resistance is small and the breathing is comfortable. Background technique [0002] At present, known masks (multi-filter masks, dust-proof type, anti-virus type, full-face mask type, half-mask type and long-tube type, etc.) have large breathing resistance and uncomfortable breathing, and everyone is unwilling to use them. Continuous use for a long time will cause damage to the lungs, so it needs to be used at intervals. The problem is mainly caused by the structure of the known mask, the filter element (filter material) with large filter area cannot be installed, and the filter element with small f...

AI Technical Summary

Problems solved by technology

[0002] At present, the known masks (multi-filter masks, dust-proof type, anti-virus type, full-face mask type, half-mask type and long-tube type, etc.) have large breathing resistance and uncomfortable breathing, and everyone is unwilling to use them.

Continuous use for a long time will cause damage to the lungs, and interval use is required

The problem is mainly caused by the structure of the known mask, the filter element (filter material) with large filter area cannot be installed, and the filter element with small filter area can only be installed (general filter material filter area is 35-70CM 2 , except for medical disposable masks, the same is true for foreign first-class masks, such as French Bagu and American 3M, etc.), the filter material has a small filtering area and large breathing resistance, so breathing is uncomfortable (the breathing air resistance per unit area is constant, the smaller the filtering area , the greater the breathing resistance, the more uncomfortable breathing, the larger the filter area, the smaller the inhalation resistance, the larger the air flow, and the more comfortable inhalation)
