CN201668888U - Single-way exhaling valve of anti-dust respirator - Google Patents

Abstract

A single-way exhaling valve of an anti-dust respirator comprises a base and an upper cover, wherein the base is a basin-shaped plastic part, the center of a basin bottom is protruded with a column body, a round hole is arranged at the center of the column body, through holes are arranged at the periphery of the basin bottom, and a groove is arranged at the inner periphery of a basin opening; the upper cover protrudes inwards, and the periphery of the upper cover is provided with a flange which is embedded into the groove at the periphery of the basin opening; the middle of the upper cover is provided with a plurality of support bars that are cross-connected and support the periphery of the upper cover; through holes are arranged among the crossed support bars; the center of the crossed-support bars is protruded with a column which is right inserted into the round hole at the center of the column at the center of the basin bottom; and a small hole is drilled at the center of a silica gel thin film, the column of the upper cover is inserted in the small hole, all through holes in the middle of the upper cover are right sealed, and the respiration air pressure of a person can lead the silica gel thin film to turn outwards or reset. The advantages are as follows: the single-way exhaling valve has simpleness in structure; after being arranged on the respirator, the single-way exhaling valve can exhaust the internal waste gas out of the aspirator immediately, quicken the internal-external air exchange speed and reduce the residence time of the exhaled gas in the respirator, thus being beneficial to the body health of a wearer.

Description

One-way breather valve of dustproof mask

Technical field

The utility model relates to a kind of outlet valve, particularly a kind of one-way breather valve of dustproof mask.

Background technology

Present existing mouth mask hide shut up, organ such as nose, though kept off external waste gas right, the waste gas that human body self is discharged can not be discharged from mouth mask soon, is unfavorable for that the mouth mask wearer's is healthy.

The utility model content

Technical problem to be solved in the utility model is will provide a kind of can discharge the one-way breather valve that remains in waste gas in the mouth mask fast.

In order to solve above technical problem, the utility model provides a kind of one-way breather valve of dustproof mask, and this outlet valve is made of base and loam cake, base is that a basin moulds materials and parts, and a cylinder is protruded at the center at the bottom of the basin, and there is circular hole at the cylinder center, the surrounding is a through hole at the bottom of the basin, and basin mouth inner peripheral is fluted; Loam cake is to projecting inward, there is the groove of flange and basin mouth periphery chimeric around it, there are several cross-coupled support bars at the middle part of loam cake, is supporting the loam cake periphery, and intersecting between the support bar is through hole, intersection support bar center protrudes out a cylinder, this cylinder just in time injects in the center hole of center column at the bottom of the basin, and a silica gel thin film centre drill one aperture pierces into the cylinder of loam cake, whole through holes at closed above middle part just in time, people's tidal air pressure energy makes silica gel thin film stick up or restore to turning up.

Described silica gel thin film diameter has at the bottom of silica gel thin film and the basin at interval less than the diameter of basin mouth.

Superior effect of the present utility model is: of the present utility model simple in structure, the utility model is placed on the mouth mask, the interior waste gas of body is by outside the utility model moment discharge mouth mask during expiration, accelerated the speed of the inside and outside exchange of air, reduced the time of staying of waste gas in mouth mask of breathing out, reduce the humidity in the mouth mask and the residual concentration of waste gas, ensured the incoming call of fresh air, helped the healthy of wearer.

The specific embodiment

Below in conjunction with accompanying drawing structure of the present utility model is further described.

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the utility model provides a kind of one-way breather valve of dustproof mask, this outlet valve is made of base 1 and loam cake 2, base 1 is that a basin moulds materials and parts, a cylinder 11 is protruded at the center at the bottom of the basin, there is circular hole 12 at cylinder 11 centers, and the surrounding is a through hole 13 at the bottom of the basin, and basin mouth inner peripheral is fluted; Loam cake 2 is to projecting inward, there is the groove of flange and basin mouth periphery chimeric around it, there are several cross-coupled support bars 21 at the middle part of loam cake 2, support 21 the loam cake periphery, intersecting between the support bar 21 is through hole 22, intersection support bar 21 centers protrude out a cylinder 23, this cylinder 23 just in time injects in the center hole 12 of center column 11 at the bottom of the basin, one silica gel thin film, 3 centre drills, one aperture 31, pierce into the cylinder 23 of loam cake 2, whole through holes 22 at closed above 2 middle parts just in time, people's tidal air pressure energy makes silica gel thin film 3 stick up or restore to turning up.

Described silica gel thin film 3 diameters have at interval at the bottom of silica gel thin film 3 and the basin less than the diameter of basin mouth.

Described silica gel thin film 3 diameters have at interval at the bottom of silica gel thin film 3 and the basin less than the diameter of basin mouth.

During use, on near near the mouth mask the nostril, open a through hole, hole size is slightly littler than one-way breather valve periphery, with the loam cake 2 of one-way breather valve in mouth mask, insert silica gel thin film 3, the cylinder 23 that base 1 central aperture loam cake 2 is protruded out inserts fastening, and all rim correspondences of loam cake 2 and base 1 cover, clamp the periphery of mouth mask perforate, make its sealing.

Claims (2)
