By protruding ear-wrapping portions backward on both sides of the mask body, the mask body can cover the face of the person and wrap the two ears at the same time. At this time, when the user wears glasses, his glasses can also be completely wrapped, so that it does not affect the normal use of myopic users.

[0036] In the above technical solution, a sealing gasket 13 is provided at the edge of the mask body 1, so that the edge of the mask body can fit tightly with the edge of the face and the ear to improve its sealing performance.

[0037] like Figure 3 and Figure 4 As shown, the above technical solution also includes a head cover 4 made of flexible material, a second mounting hole 41 is provided on the front side of the head cover 4, a wearing opening 42 is provided at the lower end of the head cover 4, the mask body 1 is installed at the second mounting hole 41, and the head cover 4 is used to be worn on the head to wrap the head, so that the respirator can also wrap the area of ​​the head except the face by the head cover.

[0038] In the above technical solution, the wearing opening 42 is provided with an elastic band 43, so that the wearing opening can be tightened around the neck under the contraction of the elastic band to improve the sealing performance of the headgear.

[0039] The elastic band 43 in the above technical solution is a rubber band, which has good contraction property.

[0040] The fabric of the head cover 4 in the above technical solution is composed of a double-layer composite of a flame-retardant inner layer 4a and a heat-insulating outer layer 4b, so that the head cover has excellent flame-retardant and heat-insulating properties and can protect the hair on the head.

[0041] like Figure 6 As shown, in the above technical solution, the flame retardant inner layer 4a is a flame retardant cotton cloth, and the heat insulating outer layer 4b is a reflective aluminum foil film, which has good flame retardant and heat insulating effects.

[0042] In the above technical solution, the breathing mask 2 is located at one end of the mask body 1 and is expanded and flexible (made of silicone or latex). It is used to seal the lips and nose. It has a simple structure and can provide further protection for the mouth and nose.

[0043] like Figure 2 , Figure 3 and Figure 7 As shown, the breathing mask 2 in the above technical solution has a filter element 21 and a one-way valve element 22 inside (wherein the one-way valve element is similar to the breathing valve on the existing mask, which is the existing technology and will not be described here), the filter element 21 is used to filter and purify the air entering the breathing mask 2, and the one-way valve element 22 is used for the air in the breathing mask 2 to be exhaled, wherein the breathing mask is similar to a mask with a filtering function, which filters the air inhaled by the mouth and nose, and the exhaled air can be directly discharged.

[0044] like Figure 5 As shown, the wearing strap 3 in the above technical solution is arranged outside the head cover 4, the wearing strap 3 is elastic and mesh-shaped, and a plurality of male buckle parts 31 are circumferentially spaced on the mesh mouth side thereof, a plurality of female buckle parts 14 are arranged on the edge of the mask body 1, and the plurality of male buckle parts 31 correspond one to one with the plurality of female buckle parts 14, and the wearing strap 3 is detachably connected to the mask body 1, so that the mask body can be better sealed and fit on the face and is not easy to loosen.

[0045] Among them, in this embodiment, triple protection can be achieved for the human mouth and nose. The first protection is the first protective barrier formed by the sealing fit between the respirator and the human mouth and nose, followed by the second protective barrier formed when the mask body fits the human face, and finally the third barrier formed by the hood wrapping the human head.

[0046] The one-way valve member in this embodiment is located in the groove of the mask, so that the air exhaled by the person is discharged from the first barrier to the second barrier. As the pressure in the second barrier continues to increase, the air therein can overflow through the edge to the third barrier. As the air pressure in the third barrier continues to increase, the head cover will gradually expand like a balloon, that is, the head cover is under positive pressure, so that the external gas can pass through the air inlet end of the breathing mask and enter the respirator after being filtered.

[0047] like Figure 7As shown, the front end of the breathing mask in this embodiment is located at one end outside the mask body and is evenly distributed with a plurality of air holes 23, and a diaphragm 24 made of non-woven fabric is arranged in front of the one-way valve member in the breathing mask 2, and the diaphragm 24 separates a compartment in the breathing mask 2, and the filter element 21 (which can be an activated carbon bag) is contained in the compartment 2. Of course, the breathing mask can also be divided into two parts, namely, the front part of the breathing mask and the rear part of the breathing mask, and the rear part of the breathing mask is fixedly connected to the mask body, and its front end is an external threaded interface, and a diaphragm and an activated carbon bag are arranged inside the front part of the breathing mask, and an internal threaded interface is arranged at the rear end of the front part of the breathing mask. At this time, the front part of the breathing mask can be replaced, so that the respirator can be reused, wherein the separation position between the front part of the breathing mask and the rear part of the breathing mask can be located at Figure 7 The position of the middle dotted line (the dotted line is located outside the mask body). The structure of the breathing mask described in this embodiment is similar to the existing industrial mask made of plastic material, so it will not be described in detail here.

[0048] The core improvement of the respirator provided in this embodiment compared to the respirator disclosed in document number CN117180584A "A portable respirator for easy addition of medicines" is that ear-wrapping parts that can wrap the ears and a head cover are added on both sides of the mask body in this embodiment. The ear-wrapping parts are added in this embodiment so that the ears can be wrapped in the mask body, thereby not affecting the wearing of glasses.

[0049] Example 2

[0050] Same as Example 1, except that Figure 8 As shown, the structure of the breathing mask in this embodiment is similar to that of an oxygen mask, which is sealed and embedded in the first mounting hole, the air inlet end of the breathing mask is located outside the mask body, and a one-way valve member located inside the mask body is provided on the side wall of the breathing mask (similar to Example 1), and the air inlet end of the breathing mask is connected to a shoulder-type gas cylinder (compressed air is filled in the gas cylinder) through a hose, so that the gas cylinder can supply air to the breathing mask for people to breathe.

[0051] Compared with the respirator, the present embodiment is equivalent to the existing positive pressure respirator on the market (the difference is that the present embodiment is provided with an ear covering portion to cover the ears).

[0052] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model.
