Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 4, the present invention provides a technical solution: the utility model provides a breather valve for virus protection gauze mask, is including installing installation department 1 on the gauze mask body, and the inner wall fixedly connected with collar 2 of installation department 1, the inside of collar 2 is provided with solid fixed ring 3, and solid fixed ring 3's outer fixed surface is connected with the anchor strut 10 that the equidistance was arranged, and the equal fixed connection in the inner wall of collar 2 of one end that solid fixed ring 3 was kept away from to every anchor strut 10, and solid fixed ring 3's inside can be dismantled and be provided with branch 4, the one end fixedly connected with valve block 5 of branch 4.

The reinforcing rod 10 is an arc-shaped strip structure, and one end of the reinforcing rod 10, which is far away from the fixing ring 3, is not located at the same horizontal line with the upper surface of the mounting ring 2, so that the face of a user can be prevented from contacting the reinforcing rod 10 when the user wears the mask.

4 sliding connection of branch has lock nut 6 in solid fixed ring 3's inside, and the surface threaded connection of branch 4 has lock nut 6, and lock nut 6 is located branch 4 and keeps away from the one end of valve block 5, and branch 4 slides and sets up in solid fixed ring 3's inside, when lock nut 6 installs on branch 4, can contact lock nut 6 and solid fixed ring 3 to the bottom surface that makes valve block 5 contacts with solid fixed ring 3's upper surface, and then can realize the fixed to branch 4.

One end threaded connection that installation department 1 was kept away from to collar 2 has protection valve body 7, and protection valve body 7 keeps away from a side fixedly connected with paster 11 of installation department 1, and the surface spraying of paster 11 has anti-fake pattern, and gas outlet 8 has been seted up to protection valve body 7's surface, and protection valve body 7's inside is provided with the filtering mechanism 9 that is used for sheltering from.

The gas outlet 8 is arranged on one side surface of the protective valve body 7 facing the ground, and can prevent the gas discharged from the gas outlet 8 from blowing to the eyes of the patient, thereby effectively avoiding the water mist phenomenon of the eyes of the patient wearing the patient in the process of spitting the gas.

Filtering mechanism 9 includes filter pulp 91, and filter pulp 91 sets up in the inside of protection valve body 7, and filter pulp 91's both ends bond respectively has slider 92 and guide block 93, will filter pulp 91 and bond with slider 92 and guide block 93 respectively, can the person of facilitating the use change the filter pulp 91 of pollution.

The inside threaded connection of slider 92 has screw rod 94, and the one end of screw rod 94 is rotated and is connected in the inner wall of protection valve body 7, and the other end of screw rod 94 runs through the surface of protection valve body 7 and extends to the outside of protection valve body 7, and the one end that screw rod 94 is located the outside of protection valve body 7 is provided with twists the piece, and the user's accessible is twisted the piece and is rotated screw rod 94 to adjust the position of slider 92 in protection valve body 7.
