Description

Antifogging mask

Technical field

It the utility model is related to mask technical field, more particularly to a kind of Antifogging mask.

Background technology

The winter temperature in the north is relatively low and is air-dried, and is influenced by winter germ, haze weather etc., more and more people are Get used to wearing mask.Mask can play the role of air filtering, isolation bacterium.But people exhalation humid air easily from The gap of mask and nose goes out to be sprayed onto on glasses, the surface of glasses is produced water mist, wearer's blurred vision is caused, to people Trip bring greater inconvenience.

The content of the invention

In view of this, it is necessary to which a kind of Antifogging mask for preventing lens surface from producing water mist is provided.

A kind of Antifogging mask, including mask body, wing of nose catch, some air outlet pipes, the wing of nose catch and some outlets Pipe is arranged in mask body, and wing of nose catch is located at the top of the inner side of mask body, is sprayed onto with the humid air for preventing people from breathing out On glasses, one end of the air outlet pipe is located at the lower section of wing of nose catch, and the other end of air outlet pipe extends to the edge of mask side, Mask is discharged from air outlet pipe to make one the gas of exhalation, unidirectional air outlet valve is equipped with the air outlet pipe, unidirectionally goes out when people's air-breathing Air valve is closed, and when people exhales, unidirectional air outlet valve is opened.

Preferably, the unidirectional air outlet valve includes unidirectional plectrum, unidirectional catch, the shape and air outlet pipe of the unidirectional plectrum Shape match, and unidirectional plectrum is pivotally connected with air outlet pipe, and unidirectional catch is fixedly connected with air outlet pipe, is unidirectionally kept off when people's air-breathing Piece is moved up to being stopped by unidirectional catch with airflow direction, so as to block air outlet pipe, is made one by mask body suction filter Air afterwards.

Preferably, the wing of nose catch is in strip, and upper end and the mask body of wing of nose catch are integrally formed, wing of nose catch tool It is flexible, to be adapted to different size and nose of different shapes.

Preferably, the front end of the wing of nose catch is connected with mask body suture, and the shape of wing of nose catch is V-shaped, to subtract The sense of discomfort of spur, wing of nose catch have elasticity, to be adapted to different size and nose of different shapes.

Preferably, the mask body is equipped with interlayer, and air outlet pipe is arranged in the interlayer of mask body, to reduce air outlet pipe The sense of discomfort caused by people, air outlet pipe is connected with mask body suture, to prevent air outlet pipe from deviating from from the interlayer of mask body.

Beneficial effect：The Antifogging mask of the utility model is equipped with wing of nose catch and air outlet pipe, and wing of nose catch can prevent people Gap of the humid air gone between mask and nose is breathed out to be sprayed onto on glasses.The humid air that air outlet pipe can breathe out people is direct Discharge, the unidirectional air outlet valve in air outlet pipe can prevent people from sucking without mask body filtered air.

Brief description of the drawings

Fig. 1 is the structure diagram of the Antifogging mask of the utility model.

Fig. 2 is the structure diagram of the unidirectional air outlet valve of the Antifogging mask of the utility model.

In figure：Antifogging mask 10, mask body 20, wing of nose catch 30, air outlet pipe 40, unidirectional air outlet valve 401, unidirectional plectrum 4011st, unidirectional catch 4012.

Embodiment

, below will be to required use in embodiment in order to illustrate more clearly of the technical solution of the utility model embodiment Attached drawing be briefly described, it should be apparent that, drawings in the following description are some embodiments of the utility model, for this For the those of ordinary skill of field, without creative efforts, it can also be obtained according to these attached drawings other Attached drawing.

Fig. 1 and Fig. 2, Antifogging mask 10, including mask body 20, wing of nose catch 30, some air outlet pipes 40 are refer to, it is described Wing of nose catch 30 and some air outlet pipes 40 are arranged in mask body 20, and wing of nose catch 30 is located at the upper of the inner side of mask body 20 Side, is sprayed onto on glasses, one end of the air outlet pipe 40 is located at the lower section of wing of nose catch 30, outlet with the humid air for preventing people from breathing out The other end of pipe 40 extends to the edge of mask side, and mask, the outlet are discharged from air outlet pipe 40 to make one the gas of exhalation Unidirectional air outlet valve 401 is equipped with pipe 40, unidirectional air outlet valve 401 is closed when people's air-breathing, and unidirectional air outlet valve 401 is beaten when people exhales Open.

Further, the unidirectional air outlet valve 401 includes unidirectional plectrum 4011, unidirectional catch 4012, the unidirectional plectrum The shape of 4011 shape and air outlet pipe 40 matches, and unidirectional plectrum 4011 is pivotally connected with air outlet pipe 40, unidirectional catch 4012 and Air outlet pipe 40 is fixedly connected, and when people's air-breathing, unidirectional catch 4012 is as airflow direction moves until being hindered by unidirectional catch 4012 Gear, so as to block air outlet pipe 40, makes one by the air after 20 suction filter of mask body.

Further, the wing of nose catch 30 is in strip, and upper end and the mask body 20 of wing of nose catch 30 are integrally formed, nose Wing catch 30 has elasticity, to be adapted to different size and nose of different shapes.

Further, the front end of the wing of nose catch 30 is connected with the suture of mask body 20, and the shape of wing of nose catch 30 is in V Type, to reduce the sense of discomfort of nose, wing of nose catch 30 has elasticity, to be adapted to different size and nose of different shapes.
