Description

Technical Field

[0001] The utility model belongs to the technical field of respiratory protective masks, in particular to a respiratory protective mask. Background Art

[0002] In coal mining operations, respiratory protection masks are essential equipment used to protect workers from various harmful gases, dust and other respiratory hazards present in the coal mining environment.

[0003] Common forms of respiratory protective masks in coal mining operations include: 1. Self-supplied respiratory protective masks: This type of protective mask provides workers with fresh breathing gas through an independent gas source (such as an oxygen cylinder), and is suitable for environments with high concentrations of toxic gases, such as hydrogen sulfide, methane, etc.; 2. Filter-type respiratory protective masks: This type of protective mask filters harmful substances in the air through a filter to provide clean breathing gas, and is suitable for dust, coal dust and low-concentration toxic gases in general coal mining operations; 3. Isolation-type respiratory protective masks: This type of protective mask completely encloses the worker's head and neck in the hood, and supplies fresh air through a breathing tube, and is suitable for high-concentration toxic gases and dust in special coal mining environments.

[0004] However, current respiratory protective masks have the following problems when used: (1) When workers wear traditional protective masks, changes in pressure inside the mask cause changes in breathing resistance, which can easily cause fatigue, and they are usually disposable, resulting in a waste of resources; (2) Air-supplied protective masks have the problem of continuous air supply, which can easily cause workers to have uncoordinated breathing. Similarly, when workers wear them, they block sound and cause communication barriers. Utility Model Content

[0039] When used specifically:

[0040] When the user wears the breathing mask, the fixing rope 21 is used to fix the breathing mask to the face. When the user inhales, the external air is filtered through the filter element 3 and the breathing channel 4 and enters the silicone mask 1. The sensor 22 contacts the air inside the silicone mask 1. At the same time, the sensor 22 detects that the pressure inside the breathing mask becomes low and sends a signal to the main board. The main board 11 controls the first motor 17 to drive the first impeller 16 to rotate, thereby increasing the pressure inside the breathing mask and maintaining the pressure balance inside the breathing mask.

[0041] When the user exhales, the sensor 22 detects that the pressure inside the breathing mask increases and sends a signal to the main board. The main board 11 controls the first motor 17 to reduce the speed of the first impeller 16, thereby reducing the pressure inside the breathing mask and maintaining the pressure balance inside the breathing mask.

[0042] At the same time, the specific gas circuit: the external air enters the breathing channel 4 through the filter element 3, and the air then enters the breathing mask through the breathing channel 4, and at the same time flows out of the breathing mask through the outlet inner cover 18, the outlet valve 19 and the outlet outer cover 20, finally forming a gas circuit.
