Referring to fig. 3, the valve cover 4 includes a top plate 41 and a fixing ring 43 which are integrally formed, the top plate 41 and the fixing ring 43 are both arranged parallel to the base 1, a sleeve 413 is arranged on one side of the top plate 41 close to the base 1 corresponding to the supporting column 21, and the supporting column 21 is embedded in the sleeve 413 and is in sliding fit with the sleeve 413; the air vent 5 is fixedly connected with the fixing ring 43 at part of the edge of the top plate 41 and is opened between the top plate 41 and the fixing ring 43. The joint groove 44 has been seted up to the inner wall of retainer plate 43, and joint piece 11 has been seted up to base 1's lateral wall correspondence, and joint groove 44 cooperates with 11 joints of joint piece to realize valve bonnet 4 and base 1's the fixed connection that can dismantle, the gauze mask person of wearing of being convenient for tears open valve 3 and washes and change.

Referring to fig. 2 and 3, in order to realize the adjustable opening and closing of the upper vent 5 of the breather valve, a baffle 6 is arranged between the top plate 41 and the base 1 and is used for covering and sealing the vent 5; the baffle 6 is rectangular and long-strip-shaped and is made of an elastic plate; the two sides of the baffle 6 in the width direction respectively abut against the inner wall of the top plate 41 and one side wall of the base 1 close to the top plate 41. Meanwhile, in order to ensure the stability of the baffle 6 on the breather valve, the base 1 is provided with an annular clamping groove 12 around the rotation axis of the base 1, the inner wall of the top plate 41 is provided with a limiting groove 411 corresponding to the annular clamping groove 12, two sides of the baffle 6 in the width direction are respectively embedded into the corresponding annular clamping groove 12 and the limiting groove 411, and the baffle 6 is matched with the base 1 and the top plate 41 in a sliding manner along the tracks of the annular clamping groove 12, the limiting groove 411 and the limiting groove 411.

When the mask wearer is in a healthy state, the mask wearer rotates the blocking piece 6 to move the blocking piece 6 away from the vent 5, so that the one-way ventilation state of the breather valve is maintained, and the occurrence of suffocation of the mask wearer is reduced; when the mask wearer is the source of disease, the mask wearer rotates the baffle 6 to the vent 5, so that the vent 5 is covered and closed; then, the wearer wears the mask; at the moment, the gas exhaled and inhaled by the mask wearer in the breathing process is filtered by the filter layer of the mask cup body, so that the surrounding people are effectively protected, and the condition that the mask wearer as a disease source infects diseases to other people is reduced.

In addition, referring to fig. 2, in order to increase the sealing effect of the blocking piece 6 on the vent 5, the rubber pad 121 and the rubber diaphragm 42 are respectively embedded in the circular clamping groove 12 and the limiting groove 411, one side edge of the blocking piece 6 in the width direction close to the base 1 is embedded in the circular clamping groove 12 and tightly abuts against the rubber pad 121, and one side edge of the blocking piece 6 in the width direction close to the top plate 41 is embedded in the limiting groove 411 and tightly abuts against the rubber diaphragm 42. Meanwhile, in order to increase the convenience of rotating the blocking piece 6 for the mask wearer, a pushing handle 61 is arranged on one side of the blocking piece 6, which deviates from the base 1, in the width direction, a sliding groove 412 is formed in the bottom wall of the limiting groove 411 on the top plate 41, and the width of the sliding groove 412 is not greater than the width of the limiting groove 411.

During the in-service use, the gauze mask person of wearing promotes according to self health status and pushes away handle 61, adjusts the position of separation blade 6 on the breather valve, realizes that the breather valve gauze mask both protected oneself and the purpose of protection peripheral crowd.

The implementation principle of the embodiment 1 is as follows: when the mask wearer is in a healthy state, the mask wearer pushes the push handle 61 to move the blocking piece 6 away from the vent 5, so that when air is sucked, air is filtered by a filtering layer of the mask and then enters the mouth and the nose; the exhaled air flows out of the mask cup body through the breathing valve, so that the occurrence of suffocation of a mask wearer is effectively reduced; when the mask wearer is the source of disease, the mask wearer pushes the push handle 61 again, the baffle 6 is rotated to the vent 5, and the vent 5 is covered and closed by the baffle 6; at this moment, the breathing process expired gas and the inhaled gas are all filtered through the filter layer of the mask cup body to the mask wearer, so that the peripheral crowd is effectively protected. By adopting the mode, the condition that the mask wearer as a disease source infects diseases to other people is reduced.

Example 2:

the embodiment of the application also discloses a mask with the breather valve.

Referring to fig. 4 and 5, a respirator is provided with a breather valve. Including gauze mask body 7, gauze mask body 7 includes non-woven fabrics filter layer 71, has seted up mounting hole 72 on the gauze mask body 7, and mounting hole 72 runs through the thickness direction of non-woven fabrics filter layer 71, and the breather valve in embodiment 1 is installed to the position that lies in mounting hole 72 on this gauze mask body 7. The difference between this embodiment and embodiment 1 is that the base 1 of the breather valve is provided with a flange 13 along one side of the base 1 axially facing away from the support frame 2, and the flange 13 extends along any radial direction of the base 1 to the periphery of the base 1.

Referring to fig. 4 and 6, when the breather valve is mounted on the mask body 7, a mask wearer firstly abuts one side of the flange 13 close to the top cover against one side of the mask body 7 close to the mouth and nose of the human body; then, covering the valve cover 4 on one side of the base 1 back axially away from the flange 13; then, the mask wearer presses the valve cover 4 and the base 1, so that the clamping block 11 is in clamping fit with the clamping groove 44, and the installation operation of the breathing valve on the mask body 7 is completed. At this time, one side of the mask body 7 departing from the mouth and nose of the human body abuts against the fixing ring 43 on the breather valve.

Referring to fig. 5, in order to ensure the stability of the breather valve on the mask body 7 and the sealing performance of the mask when the breather valve is closed, an elastic pad 45 is fixed on one side of the fixing ring 43 close to the mask body 7. After the breather valve is installed on the mask body 7, the elastic pad 45 is tightly abutted against the mask body 7.
