[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0027] like Figures 1 to 5 As shown, a gas mask that can assist breathing includes a mask body 1, a first breathing port 3, a filter component and an adjustment component. The first breathing port 3 is fixedly connected to one side of the mask body 1. This design can ensure that the components cooperate with each other to filter and adjust the filtering intensity at the same time.
[0028] Further, such as Figure 2 as well as Figure 5 As shown, the filter assembly is arranged inside the first breathing port 3 and is used to filter the air entering from the outside, thereby ensuring the anti-virus function of the mask, including an air inlet 5, which is fixedly connected to one side of the first breathing port 3. A first filter screen 6 is provided on one side of the air inlet 5, and the first filter screen 6 is fixedly connected to the inside of the first breathing port 3. A fixed plate 12 is fixedly connected to the inside of the first breathing port 3, and a second filter screen 20 is fixedly connected to the middle position of the fixed plate 12. By arranging the first filter screen 6 and the second filter screen 20, multi-layer filtration is achieved, the air filtration effect is improved, and the anti-virus function of the mask is enhanced. The position of the fixed plate 12 ensures that the air flows through the two filters, thereby ensuring the air filtration efficiency. When the mask is in use, when external air enters the mask through the air inlet 5, it is first preliminarily filtered through the first filter screen 6 fixed on one side of the air inlet 5. Then, the air that has undergone preliminary filtration enters the first breathing port 3. When the air pollution is serious, the baffle 14 can be opened by adjusting the adjustment component, so that the air continues to pass through the second filter 20 fixed in the middle of the fixed plate 12 for further filtration. The air filtered by the two layers of filters enters the interior of the mask, providing the user with clean and non-toxic breathing air.
[0029] Further, such as Figures 3 to 5As shown, the adjustment component is arranged inside the first breathing port 3 and is used to cooperate with the filter component for use. The mask filtering efficiency is adjusted according to the working conditions. It includes a lever 9, which passes through the outer wall of the first breathing port 3 and is slidably connected to the first breathing port 3. The contact position between the lever 9 and the outer wall of the first breathing port 3 is provided with an isolation sealing layer. The other side of the lever 9 is fixedly connected to a rotating ring 8, and a plurality of sliding grooves 10 are opened on the rotating ring 8. A limiting column 11 is slidingly provided inside the sliding groove 10. The other end of the limiting column 11 is fixed to a fixed plate 12. One side of the rotating ring 8 is rotatably connected to the limiting rod 13, and the other side of the limiting rod 13 is rotatably connected to a baffle 14. The baffle 1 4 is rotatably connected to the fixed plate 12, one side of the baffle 14 protrudes and the other side is recessed, and two adjacent baffles 14 can fit together and cooperate with each other. A plurality of tooth plates 15 are fixedly provided on one side of the rotating ring 8, and one side of the tooth plate 15 is meshed with a gear 16. One side of the gear 16 is fixedly connected to an extension rod 17. The outside of the rotating ring 8 is fixedly provided with a telescopic plate 7, and the end of the extension rod 17 away from the gear 16 is rotatably connected to the inner wall of the telescopic plate 7. One side of the gear 16 is rotatably connected to a connecting block 19, and the other end of the connecting block 19 is fixed to the fixed plate 12. The gear 16 is located inside the telescopic plate 7. The telescopic plate 7 is made of hard rubber on both sides and elastic rubber in the middle. One side of the fixed plate 12 is fixed There are multiple fixed rods 18 connected in a fixed manner, and the other side of the fixed rod 18 is fixed to the inner wall of the mask body 1. The number of the slide grooves 10 and the limiting posts 11 are the same and the diameter values are consistent, and they are used in conjunction with each other. Through the design of the lever 9, the rotating ring 8 and the gear 16 system, the function of adjusting the filtration efficiency according to the working conditions is realized, which improves the applicability and flexibility of the mask. When the user needs to adjust the filtration efficiency of the mask, the sliding lever 9 is adjusted, and the sliding of the lever 9 will drive the rotating ring 8 to rotate, so that the baffle 14 is opened and closed through the cooperation of the limiting post 11 and the slide groove 10. A tooth plate 15 is provided on one side of the rotating ring 8, and the tooth plate 15 is meshed with the gear 16. The gear 16 is meshed with the gear 16. The extension rod 17 is connected to the telescopic plate 7 to achieve the expansion and retraction of the telescopic plate 7. When the operating lever 9 opens the baffle 14, the rotation of the rotating ring 8 drives the tooth plate 15 to drive the gear 16 to rotate, so that the extension rod 17 presses against the middle part of the telescopic plate 7 and expands outward until it contacts and closes the inner wall of the first breathing port 3, so that the air can only be filtered from the middle part of the fixed plate 12 through the second filter 20. The gear 16 is also connected to the connecting block 19, and the connecting block 19 is fixed on the fixed plate 12 to ensure the stable operation of the gear 16. Through the coordinated work of these components, the user can change the position of the filter and the ventilation volume by adjusting the lever 9, thereby adjusting the filtration efficiency.
[0030] Further, such as Figure 1 As shown, goggles 2 are provided on one side of the mask body 1, and second breathing ports 4 are provided on both sides below the mask body 1.
