Description

Mouth bite escape device with breather valve

Technical Field

The utility model relates to a mouth bite escape device with a breather valve, belonging to the technical field of rescue and breathing auxiliary appliances.

Background

When a fire disaster occurs in a high-rise building or an accidental explosion occurs in toxic materials, besides a large fire, a large amount of black smoke and toxic gas can be generated and can instantly diffuse and permeate to the surrounding, the number of people directly burned by open fire at a fire scene only accounts for a small part of the number of dead people at the fire scene, and most of people die due to suffocation death caused by the fact that the escape opportunity is lost due to the fact that the black smoke and the toxic gas are inhaled.

In order to solve the problem, for many years, people do a lot of work for the purpose, and various fire escape devices are designed, but most of the fire escape devices are of structures with protective masks; the escape device with the protective mask has the defects of large volume, inconvenient carrying, complex operation during wearing, no use by general personnel and easy waste of the gold time for escaping. In order to overcome the disadvantages, an escape device without a protective mask is also designed, for example, patent application with publication number "CN 103816621A", which discloses an escape respirator with a simple structure, which can be contained in the mouth for breathing when a fire disaster or other rescue occurs, the container can be held by one hand, a user can hold the container in the mouth for breathing, and air inhaled by the user can flow into the container through air inlets arranged on the bottom surface and the lower side of the container, and then enter the human body after being filtered by a first filter material, a second filter material, a third filter material and a fourth filter material; although the escape device solves the problems of large volume, inconvenient carrying and complex operation during wearing, the inhaled air directly enters the human body after passing through the filter tank, and the exhaled hot air passes through the container, so that the filter material in the filter tank is easily wetted, the air permeability of the filter material is rapidly reduced, and the breathing of a user is difficult; in addition, the unobstructed time of direct filtration by the filter tank is generally short, only about 5 seconds, and the time with the ventilation and filtration function is generally only about 20 seconds, so that the protection and filtration function cannot be realized at the time, and the service time of the escape respirator is short, and the escape and rescue effect cannot be achieved.
