Description

Technical Field

[0001] The utility model belongs to the technical field of anti-choking masks, and in particular relates to an adjustable anti-choking mask. Background Art

[0002] An anti-choking mask is a facial protection device used to prevent choking and splashing from entering the mouth and nose. It is usually made of transparent plastic or other materials and covers the entire face, including the mouth, nose and eyes. Anti-choking masks are widely used in medical, industrial, laboratory, cleaning and sanitation, protection and other fields. In specific environments, such as places with a high risk of virus transmission, chemical laboratories, paint spraying work, etc., anti-choking masks can provide additional protection and reduce the risk of exposure and the spread of respiratory diseases.

[0003] A utility model patent with the patent authorization announcement number CN2737400Y discloses a mouth mask for fire escape, which is provided with a mask body roughly matching the size of a human face. The main body is composed of multiple layers of gauze and an intermediate cotton layer, and liquid chemical raw materials are added therein to make it soft and moist and to block and filter out thick smoke. The entire mouth mask can be placed in an easy-to-open can after being sterilized and vacuum-treated. When a fire occurs, the victim can easily and quickly open the can, take out the mouth mask inside, and put it on to cover the mouth, nose and face to protect the mouth and nose from inhaling thick smoke that may cause suffocation in the fire.

[0004] However, the existing anti-choking masks also have certain shortcomings. First, the existing anti-choking masks mostly use a threaded connection to fix the air intake filter cartridge and the air intake pipe. Since the threaded connection installation method requires continuous repeated rotation and cumbersome operation, it is obviously not convenient for people to disassemble and use;

[0005] Secondly, the existing anti-choking masks simply use an air intake pipe, an air intake filter cartridge, a filter element and other structures to complete the filtering of the smoke. Since the smoke contains a certain amount of moisture, it is easy to cause the filter element to get damp, which leads to poor filtering effect of the filter element. Summary of the invention

[0006] The utility model aims to provide an adjustable anti-choking mask, which solves the problem that the existing anti-choking masks mostly use a threaded connection to fix the air intake filter cartridge and the air intake pipe, and the threaded connection installation method requires continuous repeated rotation and is cumbersome to operate, making it inconvenient for people to disassemble and use; and solves the problem that the existing anti-choking masks mostly simply use the coordinated use of structures such as the air intake pipe, the air intake filter cartridge, and the filter element to complete the filtering treatment of the smoke, and since the smoke contains a certain amount of moisture, it is easy to cause the filter element to become damp, which in turn leads to the problem of poor filtering effect of the filter element.

By pulling the insertion rod to move away from the air intake filter cartridge to drive the slider to move, the spring is deformed, and then the air intake filter cartridge is pushed to be sleeved on the outside of the air intake pipe, so that the sealing strip is squeezed into the annular groove provided on the surface of the air intake pipe, and the air intake pipe is brought into contact with the fixed plate, and then the insertion rod is released to allow the spring to recover its deformation, so as to pull the insertion rod to insert into the air intake pipe, limit the air intake filter cartridge, and make the air intake filter cartridge be stably placed, which is convenient for operators to quickly install and use.

[0010] The air inlet holes opened on the surface of the air inlet filter cartridge can ensure the normal circulation of air. Under the action of the waterproof breathable membrane, the water vapor in the smoke can be removed to avoid the problem of moisture on the filter element. Under the action of the filter element, small particles of impurities in the smoke can be filtered out to avoid the choking problem of users. The output shaft is driven by the motor to rotate to drive the limit plate to rotate, and then drive the driven rod to rotate, so that the cotton piece slides along the surface of the waterproof breathable membrane, and the droplets attached to the waterproof breathable membrane are scraped off to avoid the problem of poor circulation effect of the waterproof breathable membrane.
