Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts Every other embodiment obtained, fall within the protection scope of the utility model.

Embodiment:

It as depicted in figs. 1 and 2, is a kind of embodiment of the utility model Two-way Cycle mask, the mask is according to thousand people, thousand face Man-machine face's design, using effect ingenious in design is good, one cavity of mask internal structure design, air aerodynamically Cycle applications implement Modular Structure Design technology.Specifically comprising inner casing 1 and shell 2, and be attached in described Filter screen 3 between shell 1 and shell 2, the outer rim of the inner casing 1 and the facial contact of user, the inner casing 1 and user face Accommodating chamber is formed between portion, the two sides of the shell 2 are cased with frenulum 4, and mask is placed in facial suitable position, and frenulum 4 is placed in head Portion fastens, and adjusts mask or more elasticity until comfortable.

The inner surface of the inner casing 1 is equipped with lateral isolation item 5, and the isolation item 5 is located between the mouth and nose of user, For the accommodating chamber to be divided into independent first cavity 6 and the second cavity 7 up and down.Oral area and nose is set to possess oneself independent Respiratory system, can Quick air-discharge, air-breathing filter dissipation, avoid mouth disease, influenza, internal pernicious gas row Out, atmospheric is allowed to completely cut off two small cavitys, exhaust gas does not cause cross-infection in a cavity.If being provided on the shell 2 Dry venthole 8, the shell 2 with a thickness of 1.5mm, the radial dimension of the venthole 8 is 1.5mm.

The module design of the mask oral area and nose, for the difference of mouth and the breathing pressure of nose, to two breathing modules Effective filtration area, internal space design is equipped with air outlet valve up and down, and outlet is opened, air inlet is closed, and when closing reaches Liao Guo army Mark the airtightness criteria of IP68.Specifically, nose air outlet valve 9 and mouth air outlet valve 10, the nose outlet are equipped on inner casing 1 Valve 9 and mouth air outlet valve 10 are located above and below the isolation item 5, and correspond to the nose and mouth of user； When the wearer inhales the air, the nose air outlet valve 9 and mouth air outlet valve 10 are closed；When the wearer exhales the air, the nose outlet Valve 9 and mouth air outlet valve 10 are opened.According to the volume combination aerodynamics combination human face structure of upper and lower cavities when outlet Design keeps mouth and nose breathing more smooth, and thoroughly solving the problems, such as to feel suffocated with mask exists.

It is equipped with magnet 11 in the middle position of shell 2, the corresponding position of the magnet 11 and the inner casing 1 is attracting, by institute It states filter screen 3 and is pressed on centre.Mask assembling mode while guaranteeing high efficiency filter is simpler, the filter layer of the mask The filter layer that part has oneself special for different use environments, can carry out replacing as desired according to different use environments Strainer 3, in addition all filter screens 3 have impregnates by biological agent, can avoid bacteria breed in mask more for a long time.Filtering Net 3 is disappeared using five layers of filter screen production compacting synthesis, layer of non-woven fabric, two layers of NP5 filter screen, three layers of active carbon, four layers of Chinese mugwort lucerne Kill protection medicament filter screen, five layers of hygienic non-woven fabrics.

Be fixed with the sealing ring 12 with user's direct facial contact at the outer rim of inner casing 1, the sealing ring 12 with it is described Isolation item 5 is the production of food grade silicone material, and pro-skin effect is good, and adornment is not hung when especially women is worn, and mask is interior when using Portion's not ponding, frost of not wearing glasses.The nose air outlet valve 9 and mouth air outlet valve 10 are rubber material production；The shell 2 For the production of food-grade PP material, intensity is opposed front end in current traditional mask industry, fashionable appearance, and comprehensively solve wears mouth The psychology of cover is frightened.

The Two-way Cycle Respirator structure of the utility model is simple, easy to use, and mouth and nose breathing is more smooth, has practical well Property.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection scope within.
