[0036] The following is combined with Figure 1-5 This application is described in further detail.

[0037] The embodiment of the present application discloses a filtering air supply type escape respirator.

[0038] Reference Figure 1 , comprising a filtering air supply main unit 2 and a hood 1 detachably arranged thereon, for filtering poisonous gases in the circulating environment and delivering clean gases for the wearer to breathe;

[0039] Among them, see Figure 3 As shown, the filtering air supply host 2 includes a main housing 21, a fan 24 and a gas filter canister 23; the main housing 21 is detachably arranged on the hood 1, and a flow channel for air circulation is provided between the main housing 21 and the hood 1; the gas filter canister 23 is installed at the air inlet end of the main housing 21, and is used to filter poisonous gases in the environment; the fan 24 is installed in the main housing 21, and is used to pump clean gas filtered by the gas filter canister 23 into the hood 1; the hood 1 is also provided with an elastic neck cover 13 which is easy to open and quickly put on the wearer's head, and the contact part of the elastic neck cover 13 forms a seal with the wearer's neck.

[0040] See also Figure 2 and Figure 3 As shown, the circulation channel includes an air inlet and an air outlet. The air inlet is located at one end of the main housing 21 close to the gas filter canister 23. A hole 12 is provided on the hood 1. The air inlet is located on the main housing 21. The air inlet and the hole 12 are connected. The poisonous gas enters the main housing 21 through the air inlet and then flows through the gas filter canister 23. The fan 24 pumps the filtered gas to the air outlet. The gas at the air outlet flows through the communicating hole 12 for the wearer in the hood 1 to breathe clean gas, thereby forming good air filtration in the main housing 21 and reducing the breathing difficulties caused by the poisonous gas to the wearer.

[0041] See also Figure 2As shown, the hood 1 is also equipped with a transparent window 11 for easy observation. The material of the transparent window 11 is TPU composite material. The TPU composite material has good sound permeability, wear resistance and odor resistance, is durable and scratch-resistant. The transparent window 11 ensures a larger field of view without distortion, which is convenient for the wearer to observe the escape route after wearing it.

[0042] See also Figure 2 and Figure 3 As shown, the air outlet is inserted into the hole 12 on the head cover 1, and the head cover 1 and the main housing 21 are pressed and connected by a nut 22. The head cover 1 and the air outlet on the main housing 21 are locked by the nut 22 to improve the sealing between the air outlet and the flow hole 12.

[0043] See also Figure 3 As shown, a battery 25 for powering the fan 24 is provided in the main housing 21. The battery 25 supplies power to the fan 24 as a driving source to realize the rotation of the fan 24. A switch 26 for controlling the fan 24 to be turned on and off is provided on the main housing 21. The switch 26 is installed at one end of the main housing 21 close to the hood 1 for easy manual touch and search. The switch 26 is manually adjusted to control the fan 24 to be turned on or off.

[0044] See also Figure 4 and Figure 5 As shown, the hood 1 is divided into a front piece 3 and a back piece 4, which are fixed by welding. The hood 1 composed of the front piece 3 and the back piece 4 is convenient for forming a wearing space and is convenient for the wearer to wear. The material of the front piece 3 and the back piece 4 are both TPU composite materials, which ensures that the wearer has a safe and comfortable protective environment and has good toughness. The elastic neck cover 13 is provided with a small hole centered toward the back piece 4. The small hole on the neck cover is used to increase the ventilation effect and reduce the effect on the wearer's neck.

[0045] Different models and specifications of head covers 1 are designed for children and adults respectively. For example, the size of the head cover 1 for adults is as follows: the length of the front piece 3 is 480mm and the height is 550mm, the length of the back piece 4 is 480mm and the height is 410mm, and the two are welded and fixed; the elastic neck cover 13 adopts 10mm, and the distance between the elastic neck cover 13 and the bottom of the front piece 3 is 153mm, and the distance between the elastic neck cover 13 and the top of the front piece 3 is 387mm. The transparent window 11 is installed at a distance of 70mm from the elastic neck cover 13, and the welded edge between the transparent window 11 and the front piece 3 is 10mm, the length of the upper edge of the transparent window 11 is 326mm, the length of the lower edge is 271mm, and the height is 244mm. A hole 12 of φ30mm is opened on the front piece 3;

[0046] As a children's hood 1, the specifications of the front piece 3 are 480mm*530mm, and the specifications of the rear piece 4 are 390mm*480mm. The specifications of the front piece 3 and the rear piece 4 of the children's version are smaller than those of the adult version. The installation position of the remaining holes 12 and the filtering air supply main unit 2 is consistent, ensuring the same filtering air supply system, so that the two hoods 1 with different specifications are suitable for different groups of people, which greatly improves the applicability of different groups of people.

[0047] The implementation principle of a filtering air-supply escape respirator in an embodiment of the present application is as follows: a person in an accident puts his head inside the hood 1, and the elastic neck cover 13 tightens the neck. The quick wearing method saves time for rescue and escape for the person, and it is simple and quick to wear. The elastic material is suitable for people with different face shapes. The poisonous gas in the air enters the gas filter canister 23 through the air inlet, is filtered into clean gas, and is pumped to the air outlet by the fan 24. The gas from the air outlet enters the hood 1 along the hole 12, and clean gas is supplied to the wearer in the hood 1 for breathing. The wearer in the hood 1 always breathes clean gas, which reduces the impact of the poisonous gas on the health and life safety of the wearer, and helps the wearer escape from the accident scene in time.
