Technical Field

[0001] This utility model relates to the field of fire-fighting breathing mask technology, and in particular to a fire-fighting breathing mask with anti-fogging eyepiece. Background Technology

[0002] Fire-fighting breathing masks, also known as smoke masks or escape masks, are an important type of personal protective equipment used to protect the human respiratory organs from harmful external gases at fire scenes. Fire-fighting breathing masks remove harmful gases such as carbon monoxide and smoke through adsorption, absorption, catalysis, and direct filtration by a filtration device, allowing personnel to escape during a fire.

[0003] When fire-fighting breathing masks are in use, if the temperature of the environment is high, there will be a significant temperature difference between the mask material and the environment. The saturated vapor pressure of water will decrease to below the partial pressure of water vapor in the air, causing water mist to condense on the mask surface, which will obstruct the wearer's vision and reduce the practicality of the breathing mask. Utility Model Content

[0004] The technical problem this invention aims to solve is that when the temperature of the application environment is high, a significant temperature difference occurs between the mask material and the environment, causing the saturated vapor pressure of water to decrease to below the partial pressure of water vapor in the air. This results in water vapor condensation on the mask surface, obstructing the wearer's vision and reducing the practicality of the breathing mask.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a fire-fighting breathing mask with anti-fogging goggles, including a mask body, a through hole on one side of the mask body, the mask body being made of flame-retardant cotton cloth, the outer surface of the mask body being coated with aluminum foil film, goggles being fixedly connected to one side of the mask body, a mouth cover being fixedly connected to the inner wall of the mask body, the mouth cover being made of soft rubber material, a filter sleeve being fixedly connected to one side of the outer surface of the mask body, a filter core being provided inside the filter sleeve, and an auxiliary device being provided on the outer surface of the mask body to remove water fog from the surface of the goggles.

[0006] The above-mentioned components achieve the following effects: When using a breathing mask, the mask is put on the head through the opening at the through-hole, so that the mouth cover fits the face and the mouth and nose are covered inside the mouth cover. The field of vision is observed through the goggles, and the filter element inside the filter cover can filter harmful gases in the inhaled air.

[0007] Preferably, the auxiliary device includes a controller, one side of which is fixedly connected to one side of the cover. The outer surface of the controller is provided with a control button, the inside of the controller is provided with a power supply, and one side of the controller is provided with a wire.

[0016] The effect achieved by the above components is as follows: after the mask is put on the outside of the head, the elastic band and elastic strip can be pulled to the back of the neck so that the length of the cross connection of the elastic band and elastic strip is adapted to the thickness of the neck. Then, the rubber ball on the outer surface of the round rod at one end of the elastic band is passed through the through hole on the outer surface of the cross connection of the elastic band and elastic strip to fix the cross connection of the elastic band and elastic strip, further fixing the position of the mask on the outside of the head and improving the tightness when wearing the breathing mask.

[0017] Preferably, a ring is fixedly connected to one end of the inner wall of the through hole, and the inner edge of the ring is arc-shaped.

[0018] The effect achieved by the above-mentioned components is that by setting up the ring, it is easier for the rubber ball to pass through the arc of the inner wall of the ring and enter the other side of the elastic band.

[0019] Preferably, a reinforcing ring is fixedly connected to one side of the elastic strip, and the inner wall of the reinforcing ring is fixedly connected to the outer surface of the round rod.

[0020] The effect achieved by the above components is that the connection between the round rod and the elastic strip can be reinforced by setting the reinforcing ring, thereby improving the strength of the connection structure between the round rod and the elastic strip.

[0021] The beneficial effects of this utility model are: The auxiliary device of this invention can heat the goggles by energizing the heating element, thereby increasing the temperature of the goggles and evaporating the water mist.

A heating element 23 is fixedly connected to the inner edge of the goggles 4. The end of the wire 22 away from the controller 21 is electrically connected to one side of the heating element 23. A groove 24 is formed on the outer surface of the goggles 1 near the goggles 4, and a sliding plate 25 is slidably connected to the inner wall of the groove 24 for use with breathing. If water fog forms on the surface of the goggles 4 when wearing the mask, press the control button on one side of the controller 21 to allow current to flow through the wire 22 to the heating element 23, which will heat the goggles 4 and evaporate the water fog. At the same time, push the sliding plate 25 to slide up and down on the inner wall of the groove 24, so that the sliding plate 25 moves on the outside of the goggles 4 to remove water fog and smoke from the surface of the goggles 4, so as to avoid obstructing the field of vision at the goggles 4 when wearing the breathing mask and affecting the normal use of the breathing mask.

[0029] Figure 3 , Figure 4 and Figure 5 A groove block 26 is fixedly connected to one side of the sliding piece 25 shown. Grooves 27 are provided on the upper and lower sides of the groove block 26. By pinching the two grooves 27 on the outer surface of the groove block 26, it is easier to push the groove block 26 to control the sliding piece 25 to move up and down to clean the surface of the goggles 4. A magnet 28 is fixedly connected to the top of the groove block 26, and an iron block 29 is fixedly connected to one side of the cover 1.

A reinforcing ring 37 is fixedly connected to one side of the elastic strip 31. The inner wall of the reinforcing ring 37 is fixedly connected to the outer surface of the round rod 32. By setting the reinforcing ring 37, the connection between the round rod 32 and the elastic strip 31 can be reinforced, thereby improving the strength of the connection structure between the round rod 32 and the elastic strip 31.

[0033] Working principle: When using the breathing mask, place the mask body 1 over the head through the opening at the through hole 35, ensuring the mouthpiece 6 fits snugly against the face, with the mouth and nose inside the mouthpiece 6. Pull the elastic band 34 and elastic strip 31 to the back of the neck, ensuring the length of the intersection of the elastic band 34 and elastic strip 31 is adapted to the thickness of the neck. Then, pass the rubber ball 33 on the outer surface of the round rod 32 at one end of the elastic band 34 through the through hole 35 on the outer surface of the intersection of the elastic band 34, fixing the intersection of the elastic band 34 and elastic strip 31, further securing the mask body 1 to the outside of the head. Observe the field of vision through the goggles 4. The filter element inside the filter sleeve 5 can filter harmful gases in the inhaled air. The cover 1 resists heat radiation and prevents high temperature radiation from injuring the head of the escapee in the fire. When water mist is generated on the surface of the goggles 4, pressing the control button on one side of the controller 21 allows the current to enter the electric heating element 23 through the wire 22. The heating element 23 heats up the goggles 4, causing the water mist to evaporate. At the same time, it can push the sliding plate 25 to slide up and down on the inner wall of the slide groove 24, so that the sliding plate 25 moves on the outside of the goggles 4 and scrapes away the water mist and smoke on the surface of the goggles 4.
