Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings:

as shown in figure 1, the filtering type fire-fighting self-rescuer comprises a hood 1, a mouthpiece 4 and a canister 5.

Referring to fig. 1 and 5, one end of the mouthpiece 4 is attached to the mouth and nose, and the other end of the mouthpiece 4 is connected to the outlet of the canister 5.

The mouthpiece 4 is located inside the hood 1 and is connected to the hood 1.

The mouth piece 4 is made of heat-resistant silicon rubber, is nontoxic and tasteless, is attached to the skin of a human body, and has high attachment degree with the face, large wrapping range and wide wearing application range.

The canister 5 is located outside the hood 1 and connected with the hood 1, and the canister 5 is made of ABS engineering plastics, and is non-toxic, odorless and high-temperature resistant.

Referring to fig. 2, the canister 5 comprises an upper canister 51, a smoke filter 52, an upper support plate 53, a medicine layer 54, a filter layer 55, a lower support plate 56 and a lower canister 57 from top to bottom.

The smoke filter 52, the upper deck 53, the medicine layer 54, the filter layer 55, and the lower deck 56 are stacked in this order.

The structure of the canister 5 is comprehensively determined through a large number of tests and medicine proportion, and the ratio of the inner diameter to the height, the medicine amount, the dust filtering structure and the like are determined through a large number of tests, so that the indexes of the product, such as protection performance, protection time, respiratory resistance, inspiration temperature and the like, are ensured. The drug layer consists of a layer of granular or blocky catalyst (hopcalite) and a layer of granular or blocky desiccant (canart).

The upper tank 51 and the lower tank 57 are integrally formed by injection molding, the appearance is attractive and elegant, the reinforcing ribs on the edges not only improve the strength of a product, but also increase the heat dissipation area, and the corrosion resistance of the plastic material is excellent.

The upper tank 51 and the lower tank 57 are sealed in an ultrasonic hot melting mode, the sealing strength is high, the sealing effect is good, and each gas entering the canister 5 is strictly and uniformly distributed and then filtered.

Referring to fig. 3, the smoke filter 52 includes a smoke filter housing 59 and a smoke filter membrane 58 in this order from the top.

The smoke filter casing 59 is bonded to the smoke filter membrane 58.

The smoke filter layer 52 is made of high-performance filter cotton, and the smoke filter rate is up to more than 99%.

The head cover 1 is made of high-performance aluminum coated cloth, and has excellent fire resistance and heat insulation performance.

The front end of the hood 1 is bonded with a transparent lens 2, and the transparent lens 2 is made of high-temperature resistant plastic.

Referring to fig. 1 and 4, an elastic head-wearing part 3 is sewn on the inner wall of the edge of a hood 1, the elastic head-wearing part 3 is arranged in the hood 1, the comfort degree is automatically adjusted by the elasticity when a person wears the hood, the hood is suitable for different people to wear, and the wearing time is reduced to the maximum extent.

An exhaust valve 6 is connected on the head cover 1, the exhaust valve 6 is positioned below the mouth piece 4 and is connected with the inside of the mouth piece 4, and a neck elastic band 7 is sewn at the bottom of the head cover 1.

The working principle is as follows: when a fire disaster occurs, the air contains a large amount of smoke and CO, the black smoke obstructs the observation and breathing of people, and the people are poisoned by excessive CO inhalation and cannot escape from the fire scene.

At the moment, the upper filtering type fire-fighting self-rescuer is worn, toxic and harmful gas enters the inlet of the medicine tank, smoke dust can be filtered by the smoke filtering layer 52 to reach 99 percent, CO is generated by the reaction of the catalyst and the drying agent to generate CO₂The mask 1 is made of heat insulation materials, external heat and smoke are isolated, the surrounding environment can be observed through the transparent lens 2, an escape exit is found, and people can escape rapidly.
