Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0028] As mentioned in the background art, most conventional filter boxes are assembled and disassembled in a spiral manner. However, this method requires multiple rotations, which is not convenient enough.

[0029] In order to solve this technical problem, the utility model provides a protective mask, which is used for dust prevention and protection.

[0030] Specifically, please refer to Figure 1 - Figure 5 , the protective mask specifically includes:

[0031] The mask body 1 has an outlet valve 2 and an air intake filter assembly 3 provided at the lower part of the mask body 1. The air intake filter assembly 3 is detachably connected to the mask body 1. The upper part of the mask body 1 has goggles 4 provided. The top of the mask body 1 has a lighting assembly 5 provided.

[0032] The air intake filter assembly 3 includes a filter tank body 6, and an air intake valve group 7 and an air intake valve body 8 are respectively provided at both ends of the filter tank body 6. The air intake valve group 7 is fixedly connected to the mask body 1;

[0033] The filter tank body 6 includes an outer shell 9, and the interior of the outer shell 9 is respectively provided with a filter element 10 and a filter element 2 11. The interior of the outer shell 9 and the filter element 1 10 are located on the side away from the filter element 2 11 and the side away from the filter element 1 10. The air intake valve body 1 8 is located inside the end of the outer shell 9 away from the air intake valve group 7, and the end of the outer shell 9 close to the air intake valve group 7 is detachably connected to the air intake valve group 7 through a snap-fit assembly.

[0034] The protective mask provided by the utility model, through the coordinated design of multiple structures, enables the device to achieve effective dust protection effect and reduce the occurrence of pneumoconiosis. The structural design of the air intake filter assembly 3 makes it easier and faster to disassemble and replace the filter tank body 6, effectively reducing the time required for replacing the filter part.

[0035] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] Example 1:

[0037] Please refer to Figure 1 - Figure 5 , a protective mask comprising:

[0038] The mask body 1 includes an outlet valve 2 and an air intake filter assembly 3 at the lower part of the mask body 1, the air intake filter assembly 3 is detachably connected to the mask body 1, goggles 4 are provided at the upper part of the mask body 1, and a lighting assembly 5 is provided at the top of the mask body 1; the outlet valve 2 facilitates the exhalation of air, the air intake filter assembly 3 can filter the inhaled air, the goggles 4 facilitate the field of vision after wearing the device, and the lighting assembly 5 can provide temporary lighting needs.

[0039] Specifically, the air intake filter assembly 3 includes a filter tank body 6, and an air intake valve group 7 and an air intake valve body 8 are respectively provided at both ends of the filter tank body 6, and the air intake valve group 7 is fixedly connected to the mask body 1;

[0040] Specifically, the filter tank 6 includes an outer shell 9, which is internally provided with filter element 10 and filter element 2 11. Filter element 3 12 is located within the outer shell 9, on the side of filter element 10 away from filter element 2 11 and on the side of filter element 2 11 away from filter element 1 10. Intake valve body 1 8 is located within the end of the outer shell 9 away from the intake valve assembly 7. The end of the outer shell 9 near the intake valve assembly 7 is detachably connected to the intake valve assembly 7 via a snap-fit assembly. As can be seen, when air passes through the interior of the outer shell 9, it is dually filtered by filter element 10 and filter element 2 11. After the filter tank 6 is removed, filter element 3 12 protects filter element 10 and filter element 2 11, reducing dust adhesion.

[0041] Furthermore, an external thread is provided on the outer side of the outer shell 9 away from the air intake valve group 7. Through the external thread provided at the end of the outer shell 9, the filter tank body 6 can be additionally threadedly connected to a universal filter box, thereby further improving the protection effect of the device.

[0042] Specifically, the intake valve assembly 7 includes a connecting seat 14, within which an intake valve body 18 is disposed. A movable fastener is rotatably connected to the outer side of the connecting seat 14. A fastener 13 is disposed on the inner side of the outer shell 9, near one end of the intake valve assembly 7. The outer shell 9 is fastened to the movable fastener on the outer side of the connecting seat 14 via the fastener 13. To enhance the seal between the filter tank 6 and the intake valve assembly 7, a sealing ring 19 is provided on the outer side of the connecting seat 14. The cooperation between the movable fastener and the fastener 13 allows for quick connection between the filter tank 6 and the intake valve assembly 7, effectively replacing the traditional threaded connection method and improving the efficiency of filter tank 6 replacement.

[0043] Example 2:

[0044] The protective mask provided in Example 1 is further optimized. Specifically, filter element 10 is an electrostatic filter cotton, filter element 2 11 is an activated carbon filter element, and filter element 3 12 is a sponge filter element.

[0045] Example 3:

[0046] The protective mask provided in Example 1 is further optimized, specifically, as Figure 4-Figure 5As shown, the movable buckle frame includes a rotating ring 15, which is rotatably connected to the connecting seat 14. A plurality of guide frames 16 are evenly arranged on the outside of the rotating ring 15. The guide frames 16 are arranged in a V shape, and the closed tip of the guide frame 16 is facing the direction of the filter tank body 6. Both ends of the guide frame 16 are provided with a limiting buckle groove 17. The fastener 13 is inserted into the position between the two guide frames 16, and the fastener 13 is buckled and connected with the limiting buckle groove 17 between the two guide frames 16.

[0047] Through the above-mentioned structural design, when the filter tank body 6 is connected to the intake valve group 7, the V-shaped guide frame 16 is used to make the fastener 13 contact the guide frame 16, and the guide frame 16 can be pushed to drive the rotating ring 15 to rotate outside the connecting seat 14, so that the gap between the two guide frames 16 is aligned with the fastener 13 through the rotation of the guide frame 16, and then through continuous movement until the fastener 13 is fully engaged with the limiting buckle groove 17.
