Abstract

The utility model discloses an air leakage proofing mask, wherein when in inspiration, the air directly enters a nasal cavity through a sealing channel composed of a common mask (1), a plastic sealing cover (2) and a naris respiratory tube (3) so as to realize complete filtering; and when in expiration, the expired gas is expired through the naris respiratory tube (3), the plastic sealing cover (2) and the common mask (1) and does not flow out from the periphery of the mask, thus preventing a pair of eyeglasses or the eye part from having phenomena of atomizing and frosting so as to overcome the defects of the common mask.

Description

The anti-gas-leak mouth mask

Affiliated technical field

The utility model relates to a kind of personal breathing protector, exactly is a kind of mouth mask of anti-gas-leak.

Background technology

Common mouth mask is to be strained and fixed on the face by the mouth mask rope, because people's face structure complexity, common mouth mask can not guarantee fully and face's sealing, inhaled air is filtered fully, therefore when serious communicable disease is popular, harm medical personnel and contaminated area personnel's life and health, and cause the gas of exhalation that glasses are hazed.Common mouth mask can form eyeglass fog because breath blows out through the slit between the mouth mask and the bridge of the nose when therefore wearing glasses, and winter severe cold also can form the rime ice between mouth mask edge and eyelash, the eyebrow.

Summary of the invention

The technical scheme that its technical problem that solves the utility model adopts is: a kind of mouth mask with the respiratory pipe, air directly enters nasal cavity via the seal path that common mouth mask (1), plastic cement seal closure (2), respiratory pipe (3) constitute when air-breathing, realizes filtering fully; Breath is breathed out through nostril respiratory siphon (3), plastic cement seal closure (2) and common mouth mask (1) during expiration, and the periphery from mouth mask does not flow out, and prevents that glasses or eye from atomizing, the frostization phenomenon, to overcome the above-mentioned deficiency of common mouth mask.

The utility model is by common mouth mask (1), plastic cement seal closure (2), respiratory pipe (3), plastic cement seal closure suture (4), support (5) in the seal closure and form, it is characterized in that there is plastic cement seal closure (2) common mouth mask (1) inboard, the latter is communicated with respiratory pipe (3) bottom, have in the plastic cement seal closure (2) and support (5) in the seal closure, plastic cement seal closure (2) is sewed up sealing with plastic cement seal closure suture (4) and common mouth mask (1).

Description of drawings

Further specify the utility model below in conjunction with embodiment and accompanying drawing.

Accompanying drawing 1 is a structural representation of the present utility model.

Accompanying drawing 2 is the utility model cross-sectional view.

Accompanying drawing 3 is a use principle schematic diagram of the present utility model.

The specific embodiment

Embodiment one:

In the utility model, in common mouth mask (1) inboard plastic cement seal closure (2) is arranged, the latter sews up sealing with plastic cement seal closure suture (4) and common mouth mask (1), and plastic cement seal closure (2) is communicated with respiratory pipe (3) bottom, and the nostril is inserted on respiratory pipe (3) top.

When using the utility model, earlier common mouth mask (1) is attached to face, then two respiratory pipes (3) top is inserted in the nasal cavity, because respiratory pipe (3) is generally by silica gel manufacturing and slightly thicker than the nostril, therefore airtight fully with nasal cavity, fasten at last and adjust the mouth mask rope, common mouth mask (1) is close on the face all around.

When air-breathing, the torso model expansion, in nasal cavity, form negative pressure, because of nasal cavity is tightly connected mutually with respiratory pipe (3) top, latter bottom is communicated with plastic cement seal closure (2), plastic cement seal closure (2) uses plastic cement seal closure suture (4) and common mouth mask (1) to sew up sealing again, and therefore the outer contaminated air of common mouth mask (1) can only be after common mouth mask (1) filters, and the path that constitutes via plastic cement seal closure (2), respiratory pipe (3) enters nasal cavity.And the contaminated air that the slit that forms via common mouth mask (1) and face enters can not enter respiratory pipe (3) and nasal cavity, reaches and filters the air-polluting effect of incoming call fully.

Air trafficability characteristic in order to increase when air-breathing has support (5) in plastic cement seal closure (2), plastic cement seal closure (2) and mouth mask (1) are maintained a certain distance, and prevents that mouth mask (1) is attached on the plastic cement seal closure (2) fully.

During expiration, the path that the breath via intranasal application is communicated with plastic cement seal closure (2) by respiratory pipe (3) bottom, being filtered the back by common mouth mask (1) discharges, the humid air of breathing out can not pass through mouth mask (1) and upwards blow out with the slit that people's shape of face becomes, therefore can not make mouth mask wearer's eyeglass form fog, winter severe cold can not form the rime ice between mouth mask edge and eyelash, the eyebrow yet.

The utility model is simple in structure, is easy to use, and air can be filtered fully the back and suck, and effectively anti-gas-leak and spectacle mist formation prevent the around eyes frosting that wears masks winter.

Claims

1. anti-gas-leak mouth mask, by common mouth mask, the plastic cement seal closure, the respiratory pipe supports in the plastic cement seal closure suture, seal closure and forms, it is characterized in that there is the plastic cement seal closure common mouth mask inboard, the latter is communicated with respiratory pipe bottom, has in the plastic cement seal closure in the seal closure to support, and the plastic cement seal closure is sewed up sealing with plastic cement seal closure suture and common mouth mask.
