Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and specific embodiments.

Example 1

Referring to fig. 1 to 8, the reusable mask comprises a mask body 1, wherein the mask body 1 comprises a main shell 2 and a face shell 3, an air inlet grille 4 is arranged on the face shell 3, an air guide grille 5 is arranged on the main shell 2, the face shell 3 is fastened on the main shell 2 in a buckling manner, a filter element 6 is clamped between the face shell 3 and the main shell 2, and the filter element 6 is arranged between the air inlet grille 4 and the air guide grille 5 and is used for filtering air;

the embodiment of the utility model provides an in, main casing 2 is for developing out the gauze mask structure according to the big database data of people's face, and the design is pasted according to the curve tie of people's face completely, wears the back, and people's face is hugged closely to main casing 2, and every contact surface is evenly dispersed to the pressure when wearing, and when wearing for a long time, face, ear can not have and strange mark and uncomfortable.

Preferably, the part of the main shell 2, which is in contact with the face, is made of edible transparent silica gel materials, so that the wearing is more comfortable.

Face- piece 3 and 2 looks locks of main shell, need not to beat the screw via hole, and assembly simple operation, the back is worn to 2 laminating people's faces of main shell, has ensured when breathing in, only remains the through-hole that 5 positions of air guide grid are used for admitting air on the gauze mask body 1 to through filter core 6 filtration, filter core 6 and the combination of main shell 2 make gauze mask body 1 wear the back, form an inclosed negative pressure cabin in the main shell 2.

The air inlet grille 4 is herringbone grille, and the air guide grille 5 on the main shell 2 is also herringbone grille, wherein, see fig. 4 and show, air inlet grille 4 on the face shell 3 adopts the design mode of 30 contained angles of downward sloping, the prevention rainwater gets into, crisscross setting with the air guide grille 5 on the main shell 2, and press from both sides tight filter core 6, ensure that the space that does not directly link up air inlet grille 4 and air guide grille 5 exists, when conveniently breathing in, outside air gets into filter core 6 by the hole of air inlet grille 4 earlier, filter the back by filter core 6, get into the crisscross air guide grille 5 who sets up downthehole, then the negative pressure cabin of entering face guard body 1, improve the filterable efficiency of gauze mask.

The embodiment of the utility model provides an in, filter core 6 is for crossing the filter pulp, can change the different filter cores 6 of collocation wantonly according to different environmental demands and use. Preferably, the filter cotton of the filter element 6 is prepared from petrochemical polypropylene and graphene 5.5% in proportion, and by adopting a nano-melt process and adding an inducer with a nano-structure by 3%, the filter cotton generates static electricity, so that the production of the fully transparent filter element 6 is realized effectively for 2 years.

The embodiment of the utility model provides an in, main shell 2, face-piece 3 and the filter core 6 of gauze mask body 1 all can adopt the preparation of full transparent material, can make like this take can be discerned by face identification system after gauze mask body 1, traditional opaque gauze mask then can't realize.

The embodiment of the utility model provides an in, can take out filter core 6 and change through the mode of dismantling face-piece 3, compare traditional gauze mask, reduce use cost, also reduce medical waste's production and relevant treatment cost.

Wherein, because filter core 6 presss from both sides in the middle of the face lid 3 of stereoplasm and main casing 2, consequently, can not with hand mouth nose direct contact, meanwhile, also can change a slice filter core 6 through the mode of dismantling one day, realize gauze mask body 1's repeatedly usable.

Because the mask body 1 except the filter element 6 can be made of edible high temperature resistant and acid and alkali resistant materials, the mask body can also be sterilized by the existing method during sterilization, for example, the whole mask is thrown into a pot and is sterilized by a water boiling method, or is sterilized by alcohol, or is sterilized by water bubbles and a sterilization cleaning agent, and medical wastes can be greatly reduced.

The two sides of the main shell 2 are also provided with air outlet holes 9, one-way air outlet valves 8 are mounted in the air outlet holes 9, the one-way air outlet valves 8 are arranged on the inner walls of the two sides of the main shell 2, each one-way air outlet valve 8 comprises an air outlet valve door frame 10 and a one-way air outlet blocking piece 11, the outer sides of the air outlet valve door frames 10 are connected with the one-way air outlet blocking pieces 11, and the air outlet valve door frames 10 are buckled on the main shell 2; when breathing in, the one-way air outlet valve 8 is automatically sealed, and when breathing out, the one-way air outlet valve 8 is automatically opened to give out air, so that the concentration of carbon dioxide and water vapor in the mask are greatly reduced.

Example 2

The reusable mask comprises a main shell 2 and a face shell 3, wherein the face shell 3 is provided with an air inlet grille 4, the main shell 2 is provided with an air guide grille 5, and a filter element 6 is clamped between the face shell 3 and the main shell 2.

Still be equipped with mount 7 on the main casing 2, 7 one ends of mount are connected with main casing 2, and the 7 other ends of mount are open type design, and the convenience is connected mount 7 with the neck area that is used for wearing the embodiment of the utility model provides an in, the neck area is preferred to adopt the transparent silica gel preparation, and the neck area that adopts the broad of soft silica gel directly wears at back neck position, and elasticity is good and not have the sense of pressure, has avoided traditional gauze mask to adopt two elastic cords or strap to hang on the ear, wears the ear for a long time and has the problem of reining in trace and uncomfortable.

The rest of the structure of this example is the same as example 1.

The technical principle of the present invention has been described above with reference to specific embodiments, which are merely preferred embodiments of the present invention.
