Description

The anti-mouth mask that hazes

Technical field

The utility model belongs to the articles for daily use field, is specifically related to a kind of anti-mouth mask that hazes.

Background technology

Existing common mouth mask in use, mouthful, nose all covers in the cover body of mouth mask.Winter, some people with glasses wore masks; There are the temperature difference in lens temperature and the hot gas that sheds from the mouth mask top; Thereby humid gas is met the Cold Mirrors sheet and is condensed into little water droplet, and glasses often form one deck water smoke, and not only having reduced visibility has influenced sight line; And increased danger coefficient, brought potential safety hazard for our outdoor activities.

Examine the structure of common mouth mask; We are not difficult to find: what mouth mask and people's chin and cheek were partly fitted when putting on common mouth mask is very tight; And because the main exit of the hot gas that the gap between the nose cheek that shape produces and the bridge of the nose is for we breathes out; The top of this outlet just is again the images of left and right eyes eyeglass of glasses, thereby has caused the very thin white mist of generation one deck on the eyeglass, has influenced sight line.

The utility model content

In order to eliminate this potential safety hazard, decision improves mouth mask.The mouth mask that should anti-haze is made up of bilayer, is provided with steam vent (spiracle), has changed the path that gas is breathed out and discharged, and causes hot and humid gas can not condense in eyeglass lens surface.

Concrete architecture advances technical scheme is such:

A kind of anti-mouth mask that hazes comprises mouth mask cover body 1 and tightening belt 6; The top margin middle part and the base of said cover body 1 are sewed with elastic cord respectively; Improvement is: said cover body 1 is sewed up with lower piece 3 by upper piece 2 and is formed; Joining edge one middle side part of said upper piece 2 is provided with circular arc cushion block 4, and the arcwall face of said cushion block 4 and lower piece 3 joining edges one side end face form spiracle 5.

The utility model is compared with prior art products and had the advantage of following aspect: this antifog mouth mask is easy to make; With low cost; Be fit to wearing spectacles person out using in winter; Put on this mouth mask and can play the effect of resisting face's chill and protection skin of face, and owing to the hot gas of breathing out can in time be discharged swimmingly, and breathe unobstructed.

The specific embodiment

Below in conjunction with accompanying drawing, through embodiment the utility model is done to further describe.

Embodiment:

Can discharge outside the mouth mask swimmingly for the key that solves common mouth mask drawback is the hot gas that will let respiratory nasal come out, and can not let hot gas discharge from the top of mouth mask.

Referring to Fig. 1, Fig. 2, a kind of anti-mouth mask that hazes comprises mouth mask cover body 1 and tightening belt 6; The top margin middle part and the base of cover body 1 are sewed with elastic cord respectively; Mouth mask cover body 1 is sewed up with lower piece 3 by upper piece 2 and is formed; The two-layer stitching width of upper and lower lamellar body is approximately 2 centimeters, and joining edge one middle side part of said upper piece 2 is provided with circular arc cushion block 4, and the arcwall face of said cushion block 4 and lower piece 3 joining edges one side end face form spiracle 5.

When putting on mouth mask, lower piece 3 covers face and corresponding cheek part, suture 7 just nose bottom below; And upper piece 2 covers nose and corresponding cheek part; Owing to embedded a soft cushion block with projecting shape 4 in upper piece 2 inside; The position of this cushion block 4 is fixed on the joining edge one side middle part of upper piece 2; So upper piece 2 lower end mid portions are swelled, the height highest point of protuberance is approximately about 1.5 centimeters, and forms spiracle 5 so that the hot gas that nose is breathed out is discharged the mouth mask outside from here.Because spiracle 5 both sides are all sewed up by suture 7 (see figure 3)s; So the partial width of protuberance is less, just enough discharge breathing gas usefulness, and about 2 centimeters stitching width has sheltered from nose; For nose has blocked chill, so the user can not feel nose cold or uncomfortable.Also can add one deck mull at spiracle 5 places in addition, neither influence breath, can play certain dustproof, fungi-proofing effect again.

In order to make glasses not have water smoke; At first mouth mask and people's face shape closed intensity are critical; Bridge of the nose place, cover body 1 top (limit) uses a bit of elastic cord; Cover body 1 bottom (limit) makes mouth mask be close to the cheek place with elastic cord entirely and forms an arch, and the segment elastic cord also can be sewed in the spiracle position, middle part of lower piece 3, can guarantee well can keep certain space at the mouth and nose place again with the driving fit of people's shape of face.The gas of breathing out is easily discharged from the aperture of protuberance.Secondly I adopt at the position of nose protuberance is that the strong cotton lining of gas permeability not only had been convenient to clean but also wear comfortable.
