In order to solve the problem of large breathing resistance, a respirator with a constant pressure full-face mask has electric air supply, which does not have the problem of large breathing resistance and has a good protective effect. However, this mask must use a constant pressure module to keep the pressure of the mask always present and constant, which requires a large air volume, has a very high production cost, and consumes a lot of power, resulting in poor user experience.

Such adjustments and changes to the specific setting numbers of the air intake pipes 1213 and the second through holes 112 do not deviate from the principle and scope of the present utility model, and should be included in the protection scope of the present utility model.

On the other hand, the elastic structure 113 can be deformed to make the mask 11 suitable for different groups of people, thereby greatly improving the user experience.

[0096] It should be noted that the present invention does not impose any limitation on the specific structural form of the elastic structure 113. As long as the mask 11 can be deformed and the mask 11 can always fit the user's face, etc., such adjustments and changes to the specific structural form of the elastic structure 113 do not deviate from the principle and scope of the present invention and should be included in the protection scope of the present invention.

[0097] In a specific embodiment, the elastic structure 113 is a pleated structure formed on the mask 11 , and the pleated structure includes recessed portions 1131 and raised portions 1132 that are alternately arranged in sequence.

[0098] In another specific embodiment, the elastic structure 113 is a folded structure formed by folding a portion of the mask 11 .

[0099] In another possible embodiment, the mask 11 includes a body and an elastic fabric disposed on the body, and the elastic fabric forms an elastic structure 113 .

[0100] Preferably, if Figures 3 to 5 As shown, the elastic structure 113 of the present invention is a pleated structure formed on the mask 11 , and the pleated structure includes recessed portions 1131 and raised portions 1132 that are alternately arranged in sequence.

[0101] Through such a setting, compared with setting the elastic structure 113 as a folding structure, setting the elastic structure 113 as a pleated structure formed by alternating recessed portions 1131 and raised portions 1132 in sequence can reduce the processing difficulty of the mask 11, improve the processing efficiency of the mask 11, and thus improve the processing efficiency of the mask body 1.

[0102] It should be noted that, in actual applications, those skilled in the art may set the pleated structure to be U-shaped, or may set the pleated structure to be V-shaped, or may set the pleated structure to be wavy, etc. Such adjustments and changes to the specific setting shape of the pleated structure do not deviate from the principle and scope of the present utility model and should be included in the protection scope of the present utility model.

[0103] Preferably, if Figures 3 to 5 As shown, the pleat structure is V-shaped.

[0104] It should be noted that the present invention does not impose any particular limitation on the specific setting type of the air supply component, as long as the airflow at the air outlet of the filter component 2 can be delivered to the air inlet 1214 .

[0105] In a specific embodiment, the air supply assembly includes a fan 41 and an air supply component. The output end of the fan 41 is connected to the air inlet 1214 of the mask body 1 through the air supply component, and the adjustment assembly is communicatively connected to the fan 41.

[0106] In another specific embodiment, the air supply assembly only includes a fan 41 , the input end of the fan 41 is connected to the air outlet end of the filter assembly 2 , and the output end of the fan 41 is directly connected to the air inlet 1214 of the mask body 1 .

[0107] Preferably, if Figure 1 and Figure 2 As shown, the air supply assembly includes a fan 41 and an air supply component, one end of the air supply component is connected to the output end of the fan 41, and the other end of the air supply component is connected to the air inlet 1214 of the mask body 1, and the adjustment assembly is communicatively connected to the fan 41.

[0108] Through such a setting, compared with setting the air supply component to include only the fan 41, setting the air supply component to include the fan 41 and the air supply component can more flexibly adjust the relative position between the filter component 2 and the mask body 1. At the same time, it can also realize the connection between the fan and the multiple air inlets 1214 of the mask body 1 through the air supply component, thereby meeting personalized design and further improving the user experience.

[0109] Preferably, if Figures 1 to 4 , Figure 6 There are two air inlets 1214, and the air supply component includes an air supply pipeline 421, a first branch pipe 422 and a second branch pipe 423, wherein the first end of the air supply pipeline 421 is connected to the output end of the fan 41, and the second end of the air supply pipeline 421 is connected to the two air inlets 1214 through the first branch pipe 422 and the second branch pipe 423 respectively.

[0110] By setting up two air supply components, the first branch pipe 422 and the second branch pipe 423 can be connected to the two air inlets 1214 respectively, thereby increasing the air intake volume. At the same time, it can also avoid the respiratory device from being unable to be used normally due to blockage of one of the branches or the air inlet 1214, further improving the user experience.

[0111] It should be noted that it is not limited to setting the number of air inlets 1214 to two, and setting the air supply component to include an air supply pipeline 421, a first branch pipe 422, and a second branch pipe 423. For example, the number of air inlets 1214 can also be set to only one, and the air supply component can only include one air supply pipeline 421, and so on. Such flexible adjustment and change do not deviate from the principle and scope of the utility model, and should be included in the protection scope of the utility model. Of course, preferably, the number of air inlets 1214 is set to two, and the air supply component is set to include an air supply pipeline 421, a first branch pipe 422, and a second branch pipe 423. The first end of the air supply pipeline 421 is connected to the output end of the fan 41, and the second end of the air supply pipeline 421 is connected to the two air inlets 1214 through the first branch pipe 422 and the second branch pipe 423 respectively.

[0112] It should also be noted that the present invention does not impose any particular limitation on the specific type of the filter component 2. For example, the filter component 2 can be set as a gas filter component, or the filter component 2 can be set as a dust filter component, or the filter component 2 can be set as a filter component that combines gas and dust filtering, and so on. Such adjustments and changes to the specific type of the filter component 2 do not deviate from the principle and scope of the present invention and should be included in the protection scope of the present invention.

[0113] Preferably, the filter assembly 2 includes a gas filter component and a dust filter component.

[0114] Through such a setting, the breathing device can have a dual protection effect of anti-toxic and anti-dust, improve the safety of use of the breathing device, and further enhance the user experience.
