Description

A kind of breather valve and mouth mask

Technical field

The utility model is related to breathing valve, more particularly to a kind of breather valve and the mouth mask using the breather valve, belongs to raw Product technical field living.

Background technology

In daily life and medical field, mouth mask application is more and more extensive, and traditional mouth mask is when in use due to blocking Live mouth and nose, although blocked external harmful substance etc., but the waste gas discharged to wearer itself can not be soon from mouth mask Middle discharge, in addition in flu, the breathing environment of high temperature more exacerbates the content of steam in atmosphere at mouth and nose, causes mouth and nose to be done Puckery, comfort level is poor, is unfavorable for the healthy of wearer, and this can be solved well and ask by increasing mouth mask breather valve on mouth mask Topic.

It is a kind of conventional breather valve of prior art as shown in Figure 1, generally comprises lid 13, base 12 and diaphragm 11, when Have air-flow by when, diaphragm 11 opens smaller, as shown in Fig. 2 thus capacity it is smaller, easily increase mouth mask wearer feels suffocated Sense.

Utility model content

In order to solve the above problems, the utility model proposes a kind of breather valve, including upper lid, base and diaphragm, institute State lid and the center fixing part of the base and pass through its center, the membrane surface be disposed radially two it is recessed Groove.

Especially, the groove is arranged on the lee face of the diaphragm.

Especially, the depth of groove is the 1/5 ~ 1/3 of the diaphragm thickness.

Especially, the depth of groove is the 1/4 of the diaphragm thickness.

Especially, the recess width is 0.5mm ~ 3mm.

Especially, the recess width is 1mm.

Further, the upper lid includes outer ring support, central cover and connects the outer ring support and the center Multiple connecting rods of cover plate, plane where the outward flange of the central cover is flat higher than where the inward flange of the outer ring support Face.

Especially, the connecting rod of the upper lid is arch.

Especially, the spill being recessed centered on the central cover to its center.

The utility model also proposes a kind of mouth mask, including mask body and the elastic threads for being fixed on mask body two ends, Also include the breather valve being arranged in the mask body, the breather valve is above-described breather valve.

The diaphragm of the utility model breather valve can be opened in expiration state such as pinion shape heavy caliber, so that the row of adding Tolerance, and apply this breather valve mouth mask because exhale when capacity increase, the sense of feeling suffocated of mouth mask wearer can be mitigated.

Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model Art means, and being practiced according to the content of specification, and in order to allow above and other purpose of the present utility model, feature It can be become apparent with advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, describe in detail as follows.

Embodiment

To make those skilled in the art more fully understand the technical solution of the utility model, with reference to Fig. 3, Fig. 4 and Fig. 5 And embodiment is described in further detail to the utility model.

The breather valve of the present embodiment, including upper lid 23, base 22 and diaphragm 21, there is a through hole at the center of diaphragm 21 212, there is mounting post the position corresponding with the center of diaphragm 21 on upper lid 23, in the position corresponding with the center of diaphragm 21 of base 22 Put with mounting cylinder, mounting post is passed through after through hole 212 in insertion mounting cylinder, so that upper lid 23, diaphragm 21 are fixed with base 22 Together.Fixed form is not construed as limiting or mounting post is arranged on base 22, and mounting cylinder is arranged on lid 23.

As shown in figure 3, being disposed radially two grooves 211 on the lee face of diaphragm 21, the depth of groove 211 is diaphragm The 1/5 ~ 1/3 of thickness, preferably 1/4.Preferably, the thickness of diaphragm 21 is 0.4mm, the depth of groove 211 is 0.1mm.It is recessed The width of groove 211 is 0.5mm ~ 3mm, preferably 1mm.

It should be noted that groove 211 can also be arranged on the windward side of diaphragm 21.

As shown in figure 4, when breather valve is in expiration state, diaphragm 21 is opened, due to the presence of groove 211, diaphragm 21 It can be opened such as pinion shape heavy caliber, so as to add capacity.

As shown in figure 5, upper lid 23 includes outer ring support 231, central cover 232 and connects the outer and of ring support 231 Multiple connecting rods 233 of the central cover 232, plane A is higher than the outer shroud branch where the outward flange of the central cover 232 Plane B where the inward flange of frame 231, can so make that the outward flange of diaphragm 21 lifts is higher, that is, increases opening for diaphragm 21 Angle.On the other hand, for external dimensions size identical breather valve, such design can select the diaphragm of larger diameter, That is the ventilation aperture of base（During suction condition, ventilation aperture envelope piece covering）What can be done is bigger, so that further Increase capacity.

The connecting rod 233 of upper lid 23 connects the inward flange of outer ring support 231 and the outward flange of central cover 232, outer shroud branch Frame 231, central cover 232 and connecting rod 233 can be formed in one design.

The connecting rod 233 of upper lid 23 can be inclined straight for the therefrom outside inward flange of ring support 231 in the outward flange of heart cover plate 232 Bar, but preferably arch, higher, the opening angle of further increase diaphragm 21 that the outward flange of diaphragm 21 can so lifted.

In the present embodiment, the outer shape of breather valve is circle, thus central cover 232 is disc, outer ring support 231 For annular, but it is not limited thereto, the outer shape of breather valve can also be oval, square etc., and then design corresponding Central cover and outer ring support shape, the shape that heart cover plate and outer ring support are misaligned herein are construed as limiting.

In the present embodiment, central cover 232 is that spill, the i.e. center of central cover 232 are recessed to the center position of diaphragm 21, Central cover can also be convex or plate shaped, be not limited thereto.

The present embodiment also includes a kind of mouth mask, including mask body, is fixed on the elastic threads at mask body two ends, Yi Jishe The breather valve being placed in the mask body, breather valve is above-described breather valve, be will not be described in great detail herein.Exhaled using above-mentioned The increase of capacity, can mitigate the sense of feeling suffocated of mouth mask wearer when inhaling the mouth mask of valve because exhaling.

It is understood that embodiment of above be merely to illustrate that principle of the present utility model and use it is exemplary Embodiment, but the utility model is not limited thereto.For those skilled in the art, this is not being departed from In the case of bright spirit and essence, various changes and modifications can be made therein, and these variations and modifications are also considered as the utility model Protection domain.
