Description

Technical Field

[0001] This utility model relates to the field of fire-fighting mask technology, specifically to a fire escape gas mask. Background Technology

[0002] Gas masks used for escape, also known as fire-fighting filtering self-rescue respirators, are essential equipment for ensuring breathing safety in emergencies such as fires. They typically consist of a face mask and a filter canister. The face mask fits snugly to the face, preventing harmful gases from entering. The filter canister contains special adsorbents and filter materials that effectively filter toxic and harmful gases such as carbon monoxide and smoke. To use, simply remove the mask, unfold it, put it over your head, and tighten the straps. This provides the wearer with a safe breathing environment for a limited time, helping people escape quickly from fire smoke and ensuring their safety.

[0003] Currently, there are several pressing issues with gas masks used for fire escape. The internal filter structure is relatively simple, relying on only a single layer of filter cotton to filter harmful gases, which is ineffective in complex fire environments. Regarding the wearing method, the silicone type completely covers the head, which, while blocking gases, causes significant discomfort, leading to stuffiness and pressure after prolonged wear. Furthermore, fires are often accompanied by power outages, plunging the surroundings into darkness, and gas masks lack illumination, obstructing the user's vision and significantly increasing the difficulty of escape. Moreover, wearing a gas mask already limits visibility, further increasing the risk of escape. Utility Model Content

[0004] To solve the above-mentioned problems, this utility model proposes a fire escape gas mask that is comfortable to wear, has a multi-layered filter canister, and has a lighting function.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a fire escape gas mask, comprising:

[0006] The mask has a transparent viewing window, an inhalation port, and an exhalation mouth on the front side wall from top to bottom. A sound-emitting mouth is also provided on the front side wall near the exhalation mouth. A light is detachably installed on the top of the mask, a fixing strap is detachably installed on the rear side, and a storage box is detachably installed on the bottom of the mask.

[0007] A filter canister, detachably mounted at the air intake, includes a canister body, a bottom sealing cap, and a top sealing cap. The bottom sealing cap and the top sealing cap are detachably mounted at the bottom and top of the canister body, respectively. Inside the canister body, from the bottom to the top, a smoke filter layer, a first filter screen, a first filter cotton pad, a chemical layer, a second filter screen, and a second filter cotton pad are arranged sequentially.

[0008] Furthermore, the sound-emitting mouth includes an annular seat, the front end of which is detachably provided with a transparent spring, the front end of which is provided with a stop strip that matches the transparent spring, the front side of which is threadedly connected with a fixing ring for fixing the transparent spring, and a washer is provided at the contact point between the rear edge of the fixing ring and the transparent spring.

[0009] Furthermore, the lighting lamp is equipped with a battery, the upper wall of the mask is provided with a lamp holder, and a shaping hose is fixedly provided below the lighting lamp, with the lower end of the shaping hose magnetically attached to the lamp holder.

[0010] Furthermore, the fixing strap is a T-shaped silicone strap, the ends of which are fixed to the upper wall and the two side walls of the mask by buckles.

[0011] Furthermore, the storage box is a pull-out drawer type, and the lower end of the mask is provided with a pull-out groove that matches the storage box.

[0012] Furthermore, the can opening sealing cap is threadedly connected to the can opening of the can body, and the inner side of the can opening sealing cap and the can opening of the can body are respectively provided with matching threads one and thread two, the air intake is provided with thread three matching thread two, and the inner side of the can opening sealing cap is provided with a can opening sealing gasket matching the can opening.

[0013] Furthermore, an instruction label is provided on the side wall of the tank.

[0014] Compared with existing technologies, the advantages of this invention are as follows: the fixing strap on the back of the mask is a T-shaped silicone strap, which is soft and fits better against the head, reducing pressure on the skin and providing a comfortable wearing experience. At the same time, the ends of the fixing strap are secured to the upper and side walls of the mask via buckles. This design makes the mask more securely fixed to the head, effectively ensuring the stability of the mask during use and preventing shaking from affecting its effectiveness.

[0015] The filter canister has a sophisticated internal structure, consisting of a smoke filter layer, a first filter screen, a first filter pad, a chemical agent layer, a second filter screen, and a second filter pad, arranged sequentially from the bottom to the opening. This multi-layered structure works in tandem: the smoke filter layer first filters smoke particles, the filter screen further intercepts impurities, the filter pads adsorb tiny particles, and the chemical agent layer chemically adsorbs and reacts with toxic gases, achieving comprehensive and efficient filtration and providing reliable respiratory protection for the user.

[0016] A detachable light fixture with a built-in battery is mounted on top of the face mask, eliminating the need for an external power source and making it more flexible and convenient to use. The lamp holder comes with a flexible tube, allowing users to adjust the lighting angle to suit their needs. Furthermore, the flexible tube attaches magnetically to the lamp holder at the bottom for easy and quick installation and removal, facilitating use and storage in various scenarios.
