Description

Technical Field

[0001] The utility model relates to the technical field of masks, in particular to a dust-proof inflatable mask. Background Art

[0002] With the air pollution caused by the advancement of science and technology, masks have become one of the essential items in people's lives. They are worn on the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, and droplets from entering and exiting the wearer's mouth and nose. Therefore, wearing a mask is an important protective and epidemic prevention measure for people's health.

[0003] Many factories generate dust continuously during production, so workers need to wear dust masks. At present, dust masks mainly use thicker mask filter membranes and air filter elements or activated carbon boxes to improve dust removal rates. After wearing thicker mask filter membranes, a lot of dust will accumulate on the mask in a short period of time, and the dust removal effect of the mask will be greatly reduced, which is harmful to health. Masks with air filters or activated carbon boxes can greatly increase the use time and maintain a good dust removal effect. However, due to the large mass of activated carbon and air filters, the breathing resistance is large, which will cause discomfort to workers who work continuously.

[0004] In view of this, a dust-proof inflatable mask is urgently needed. Summary of the invention

[0005] In view of the problems existing in the prior art, the utility model solves the problems with the following technical structure.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A dustproof inflatable mask, comprising: a first mask layer, an air cavity formed outside the first mask layer, and a connecting device;

[0008] The connecting device includes an air inlet, an air pressure regulating device and an air outlet. The air inlet is arranged outside the air cavity. The air inlet is externally connected to an air pipe. The air pressure regulating device regulates the air pressure of the gas input into the air inlet. The air outlet is arranged inside the air cavity.

[0009] Its further characteristic is that

[0010] A second mask layer is disposed outside the first mask layer, the second mask layer is connected to the peripheral side of the first mask layer, and an air cavity is formed between the first mask layer and the second mask layer.

[0011] The connecting device is passed through the second mask layer, and the air inlet is arranged on the outer side of the second mask layer.

[0012] The first mask layer is made of non-woven fabric.

[0013] The second face cover layer is made of non-woven fabric.

[0014] U-shaped ear hooks are provided on both sides of the first mask layer.

[0015] A nose bridge fixing component is arranged on the first mask layer.

[0016] The nose bridge fixing component is an aluminum strip.

[0017] The air pressure regulating device is provided with a manual regulating switch.

[0018] A quick interface is arranged at the air inlet.

[0019] The above structure of the utility model can achieve the following beneficial effects:

[0020] When in use, the air inlet is connected to the air supply pipe, the input gas is pressure-regulated by the air pressure regulating device, and then output from the air outlet to the air cavity. Harmless gas fills the air cavity, and the user inhales the air in the air cavity through the first mask layer without breathing polluted air in the workplace, thereby preventing workers from inhaling dust and affecting their health. A lot of dust will not accumulate on the mask after working for a long time. This product has low breathing resistance and improves the comfort of the user. BRIEF DESCRIPTION OF THE DRAWINGS
