Preferably, the first air inlet and the second air inlet are both one-way air inlets, and the one-way air inlets are of two-flap air inlet structures.
Preferably, the exhaust part is a one-way exhaust port, and the one-way exhaust port is of a three-flap exhaust structure.
Preferably, the outer diameter of the exhaust part is smaller than the sum of the outer diameters of the first and second intake ports.
Preferably, the first nonwoven layer has a porosity greater than the porosity of the second nonwoven layer.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model sets the mask body into a water drop shape, and the fixing band and the left and right hangers are mutually matched, so that the mask body is closely attached to the face, and the problem that the attaching performance of the mask body and the face is poor along with the prolonging of the service life is avoided; the pressure drop inside and outside the breathing mask is adjusted by arranging the air inlet part and the air outlet part, so that the use comfort of the breathing mask is ensured; the protective device is arranged at the air inlet part, and the chitosan slow release property is utilized to gradually release the sterilizing quaternary ammonium salt, so that the gas is effectively sterilized, a user is protected powerfully, and the service life of the mask body is prolonged.

fig. 2 is a schematic view of a first air inlet structure of the present invention;
FIG. 3 is a schematic view of the exhaust unit of the present invention;
fig. 4 is a schematic structural diagram of the protection device of the present invention.
In the figure: 1. a mask body; 2. fixing belts; 3. a left suspension loop; 4. a right suspension loop; 5. a first air inlet; 6. a second air inlet; 7. a first nonwoven layer; 8. a filtration and anti-bacterial layer; 9. a second nonwoven layer; 10. an isolation ring; a one-way vent.
Detailed Description
The invention will be further explained with reference to the drawings and the detailed description below:
as shown in fig. 1-4, a respiratory mask with a protection device comprises a mask body 1 attached to the face of a user, an air inlet part arranged at the upper end of the mask body 1 and an air outlet part arranged at the lower end of the mask body 1, wherein the cross section of the mask body 1 is in a drop shape, a fixing band 2 fixed on the head is arranged at the rear end part of the upper end attached to the nose bridge, the lower end is attached to the face of the human body, a left hanging lug 3 and a right hanging lug 4 are respectively arranged at the left end and the right end of the air inlet part, the air inlet part comprises a first air inlet 5 and a second air inlet 6 which are arranged side by side at the left end and the right end of the air inlet part, the surfaces of the first air inlet 5 and the second air inlet 6 are both provided with the protection device, the protection device comprises a first nonwoven fabric layer 7, a filtering antibacterial layer 8 and a second nonwoven layer 9 which are sequentially covered from the outside to the inside, the filtering antibacterial layer 8 is chitosan quaternary ammonium salt, the air outlet part is arranged below the air inlet part, and the air outlet part is a one-way air outlet 11, the one-way exhaust port 11 is of a three-flap exhaust structure, and a polyurethane isolation ring 10 is arranged on the edge of the inner side of the mask body 1 in a surrounding mode. Set up the face guard into the water droplet form, make it make face guard body 1 closely laminate face through fixed band 2, left hangers 3 and right hangers 4 when laminating face, avoid the face guard because of using for a long time lax, and then with the untight problem of facial laminating. The polyurethane isolation ring 10 is arranged on the inner side of the mask body 1, so that the mask body 1 is tightly attached to the face, and meanwhile, the oppression feeling is avoided, and the polyurethane isolation ring 10 can absorb sweat generated by the skin of the face, so that the face is ensured to be dry and comfortable. Through setting up protection device in the air inlet part, utilize first non-woven fabric 7 to carry out the prefiltration, filter the quaternary ammonium salt in the antibacterial layer 8 and disinfect to the air, the slowly-releasing granule of chitosan has then guaranteed gradually releasing of quaternary ammonium salt, makes the face guard live time obtain the extension.
The first air inlet 5 and the second air inlet 6 are both one-way air inlets, and the one-way air inlets are of two-flap air inlet structures. The one-way air inlet is set to be of a two-valve structure, so that one-way air flow is formed, and air backflow is avoided.
The outer diameter of the exhaust portion is smaller than the sum of the outer diameters of the first intake port 5 and the second intake port 6.
The porosity of the first non-woven fabric layer 7 is greater than the porosity of the second non-woven fabric layer 9. The effect of primary filtration and depth filtration is achieved by controlling the porosity of the first non-woven fabric 7 and the second non-woven fabric 9.
The utility model discloses when using, cover face guard body 1 in face, be fixed in the head with fixed band 2 behind the 1 upper portion laminating bridge of the nose of face guard body, left hangers 3 and right hangers 4 hang into left ear and auris dextra respectively, the user freely breathes through the inlet unit, gaseous entering after 7 prefilters of first non-woven fabrics is filtered and is filtered antibacterial layer 8, pass second non-woven fabrics 9 and get into human respiratory track after quaternary ammonium salt disinfects, because the two lamella structures of first air inlet 5 and second air inlet 6, the exhalation gas only can be discharged by exhaust unit, effectively prevent the propagation of taking the fungus gas in the air.
In summary, the present invention is only a preferred embodiment, and is not intended to limit the scope of the present invention, and all equivalent changes and modifications in the shape, structure, characteristics and spirit of the claims of the present invention should be included in the scope of the claims of the present invention.
