Description

Technical Field

[0001] The present invention relates to the technical field of face masks, and particularly to an integrated air supply valve face mask. Background Art

[0002] An air supply valve face mask is a key device for respiratory protection, commonly used in fields such as firefighting, industrial safety, and medical first aid. It provides clean air or oxygen for users by connecting to an external air source (such as an oxygen cylinder) to ensure safe breathing in a dangerous environment.

[0003] Currently, the existing air supply valve face masks have the following defects:

[0004] 1. Visual distortion affects the clarity and safety of the field of vision.

[0005] 2. An external air source needs to be used immediately after wearing. When not in an environment where breathing is not suitable, the air in the air source is consumed, reducing the usage duration of the air source in an environment where breathing is not suitable.

[0006] 3. The wearer needs to lower their head to check the pressure gauge to observe the air pressure status in the gas cylinder, resulting in distraction of attention and increasing danger.

[0007] 4. The sound conduction ability is limited, resulting in obstacles to communication between wearers. Summary of the Invention

[0008] In view of the defects in the prior art, the present invention provides an integrated air supply valve face mask. This device can connect the inside of the face shield with the external environment when not in an environment where breathing is not suitable, and at the same time cut off the connection between the air supply pipeline and the face shield, reducing the consumption of air in the gas cylinder and increasing the usage duration of the gas cylinder in an environment where breathing is not suitable.

[0009] An integrated air supply valve face mask includes a face-hugging mask, a face shield, and an air supply component. The face-hugging mask is fixedly attached to the inner wall of the face shield, and straps are connected to the face shield.

[0010] An oral-nasal mask is fixed inside the face shield, and an air supply component is connected to the face shield. The air supply component has an air supply pipeline, the air supply pipeline is connected to an air supply tube, and the air supply tube is connected to an external air source. An ambient air bypass device is provided inside the air supply component. The ambient air bypass device can connect the air supply pipeline with the inside of the face shield, and the ambient air bypass device can cut off the connection between the air supply pipeline and the face shield when the inside of the face shield is connected to the external environment.

[0011] Preferably, a quick connector is provided on the air supply component, and the quick connector is used to connect the air supply tube.

[0012] Preferably, there are two air supply pipelines inside the air supply component, and a purge valve is provided in one of the air supply pipelines.

[0013] Preferably, a through hole is formed in the air supply assembly, and the ambient air bypass device is slidably arranged in the through hole. A groove is provided on the top wall of the through hole. Ventilation holes corresponding to the two air supply pipes are formed in the ambient air bypass device. A toggle piece is arranged on the air supply assembly, and the toggle piece can drive the ambient air bypass device to move upward. The top of the ambient air bypass device enters the groove to open the lower part of the through hole. At the same time, the ventilation holes are misaligned with the air supply pipes to cut off the gas supply of the air supply pipe.

[0014] Preferably, a pressure head-up display device is fixed to the outer wall of the air supply assembly. The pressure head-up display device has three air pressure indicator lights, a pairing indicator light, and a power indicator light.

[0015] Preferably, a microphone is arranged inside the face shield.

[0016] Preferably, an NFC pairing component is connected to the pressure head-up display device.

[0017] Preferably, the face shield is made of polycarbonate material.

[0018] The beneficial effects of the present invention are as follows: In this technical solution, an air supply assembly is provided, and the air supply assembly has an air supply pipe. By providing an ambient air bypass device, when entering an environment where it is not suitable to breathe, the air supply pipe is communicated with the inside of the face shield. Before entering an environment where it is not suitable to breathe, the ambient air bypass device communicates the inside of the face shield with the external environment, and at the same time cuts off the connection between the air supply pipe and the face shield. In this way, the air consumption of the gas cylinder can be reduced, and the service life of the gas cylinder in an environment where it is not suitable to breathe can be increased.
