[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 A mask with a conveniently adjustable mask strap comprises a mask body 1, a nose clip 2 is fixedly connected to the front of the mask body 1, a mask strap body 3 is fixedly connected to the outside of the mask body 1, and an adjustment device 4 is arranged on the outside of the mask strap body 3;

[0021] The adjusting device 4 includes an equipment box 401, a spring 402, a slide plate 403, a slide bar 404, a pressing block 405, a first mounting block 406, a limiting column 407, a second mounting block 408 and a fixing hole 409. The equipment box 401 is arranged on the outside of the mask strap body 3, the spring 402 is fixedly installed on the inner bottom wall of the equipment box 401, the slide plate 403 is fixedly installed on the top of the spring 402, the slide bar 404 is fixedly installed on the top of the slide plate 403, the pressing block 405 is fixedly installed on the top of the slide bar 404, the first mounting block 406 is fixedly installed on the outside of the equipment box 401, the limiting column 407 is fixedly installed on the front of the first mounting block 406, the second mounting block 408 is fixedly installed on the outside of the equipment box 401, and the fixing hole 409 is arranged inside the second mounting block 408.

[0022] Specifically, Figure 2 As shown, the material of the spring 402 is stainless steel wire, which has the advantages of corrosion resistance, strength and rigidity, aesthetics, high temperature resistance, high fatigue strength, good plasticity and toughness, and suitability for harsh environments.

[0023] Specifically, Figure 3 As shown, when the mask needs to be worn, fit the mask body 1 to the face, and then cooperate with the second mounting block 408 and the fixing hole 409 through the first mounting block 406 and the limiting column 407, insert the limiting column 407 into the fixing hole 409, and then press the nose clip 2 to complete the wearing. When it needs to be removed, the limiting column 407 can be pulled out from the fixing hole 409 to remove the mask.

[0024] Specifically, Figure 2 As shown, the mask strap body 3 passes through the device box 401 and the slide bar 404. When adjustment is needed, the pressing block 405 can be pressed to align the through holes opened in the device box 401 and the slide bar 404. After alignment, the length of the mask strap body 3 can be adjusted. After the adjustment is completed, release the pressing block 405, and the slide bar 404 will move up under the action of the spring 402, thereby blocking the position of the mask strap body 3 in the device box 401 to prevent the mask strap body 3 from sliding during use.

[0025] When implementing, follow these steps:

[0026] 1) First, fit the mask body 1 to the face;

[0027] 2) Then wear the mask through the limiting column 407 and the fixing hole 409;

[0028] 3) Adjust the length of the mask strap body 3 by pressing the pressing block 405;

[0030] To sum up, for the mask with easy-to-adjust mask strap, when the mask needs to be worn, the mask body 1 is first fitted to the face, and then the mask is fixed by the first mounting block 406 and the limiting column 407 in cooperation with the second mounting block 408 and the fixing hole 409, so as to achieve the purpose of easy wearing. After wearing, by pressing the pressing block 405, the pressing block 405 will drive the slide bar 404 and the slide plate 403 to compress the spring 402. After compression, the through holes opened in the device box 401 and the slide bar 404 correspond to each other, and the length of the two mask strap bodies 3 can be adjusted by pulling. After adjusting to the appropriate length, release the pressing block 405, and the slide bar 404 will rise under the action of the spring 402, so as to fix the mask strap body 3, so as to achieve the purpose of adjusting the length of the mask strap body 3 by the adjustment device 4 for users with different head circumferences, which is convenient for users with various head circumferences.
