Further, the edge of the outer surface of described valve gap is provided with triangle polyester fibre projection.
Further, the sidepiece of described valve gap is provided with three air-vents.
Further, described base is provided with location instruction groove, and the position of described location instruction groove is corresponding with the position of location stacker.
Band valve Collapsible containment mouth mask, comprise above-mentioned outlet valve and mask body, the both sides of described mask body are provided with the headband that cover is hung on ear, the top in the outside of described mask body is provided with bridge of the nose bar, the middle part of described mask body is arranged with impression, and the middle part of described mask body side is provided with described outlet valve.
A kind of preferred version as with valve Collapsible containment mouth mask in the utility model: the base of outlet valve welds with described mask body.
Beneficial effect: outlet valve disclosed in the utility model and band valve Collapsible containment mouth mask have following beneficial effect:
1, outlet valve can discharge hot gas in time, stops hot gas upwards to spread;

Detailed description of the invention:
Below detailed description of the invention of the present utility model is described in detail.
As shown in figs. 1 to 6, outlet valve, comprises expiration valve block 53 (adopting silica gel to make), base 52 and valve gap 51,
Base 52 is provided with location stacker 521,
The sidepiece of valve gap 51 is provided with at least one air-vent 513, and the inner side of valve gap 51 is provided with locating dowel 512 (locating dowel 512 act as adjustment airflow direction, prevent from expiration valve block 53 turns over),
Expiration valve block 53 and base 52 clamping (be provided with a through hole in the middle part of base 52, expiration valve block 53 snaps in through hole), base 52 and valve gap 51 are by locating stacker 521 and the clamping of locating dowel 512 releasable.
Further, the edge of the outer surface of valve gap 51 is provided with triangle polyester fibre projection 511, and it act as instruction location, and person easy to use installs, thus it is errorless to reach accurate positioning.。
Further, the sidepiece of valve gap 51 is provided with three air-vents 513, and it act as reduction expiratory resistance, the comfort level of adding users.
Further, base 52 is provided with location instruction groove 522, the position of location instruction groove 522 and the position corresponding (locating with the corresponding dual control that realizes of locating dowel 512) of location stacker 521.
