A fan filter 13 is attached to the outside of the peripheral wall portion of the goggles 11 with respect to the outside air introduction hole 113, and the inside of the peripheral wall of the goggles 11 with respect to the outside air introduction hole 113 is ultra-compact that can rotate within 10V. The formed outside air introduction fan 14 is attached.

  The cooling air blowing unit 15 is disposed on the downstream side front surface of the outside air introduction fan 14 along the air blowing direction. Further, a fan push button switch 18 for operating the outside air introduction fan 14 is mounted on the peripheral wall portion 112 corresponding to the upper portion of the goggles portion 11. The peripheral wall portion 112 is formed with an appropriate number of air holes for discharging internal air at an appropriate position, and further has one hole for wiring between the outside air introduction fan 14 and the battery 19 described later. Is formed.

  The mask part 12 is below the goggle part 11, and the front center part 121 of the mask part 12 is formed in a convex shape from the front of the nose part toward the front of the mask part 12 to cover the nose part of the wearer. It is formed so as to protrude into the upper goggles 11. Inside the front central portion 121, a battery 19 formed in a very small size capable of outputting a voltage of about 10V is mounted at a position where it does not interfere with the wearer's nose. A check valve exhaust port 21 is attached to the lower part of the front central portion 121 of the mask unit 12, and air exhausted from the port is discharged to the outside of the mask unit 12. Further, a pair of breathing ports 22 for sucking air are formed on both sides of the lower portion of the mask unit 12, and a carbon monoxide removing agent is mounted in each of the breathing ports 22.

  The fan filter 13, the outside air introduction fan 14, and the cooling air blowing unit 15 are arranged as shown in FIG. 3. Note that the arrows indicate the flow of air, and the air flows from the fan filter 13 side, which will be described later, disposed outside the peripheral wall 112 of the goggle part 11 to the mesh 17 side, which will be described later in the goggle part 11.

By operating the fan push button switch 18, a slight electric power within 10V is obtained. But it is configured to rotate.

  The cooling air blowing unit 15 according to the embodiment includes an instantaneous coolant coolant 16 and a mesh 17 disposed on the air flow downstream side front surface of the instantaneous coolant coolant 16. A chemical reaction water container cassette 161 serving as a water storage container having a pull cord 161 a is disposed above the front surface of the outside air introduction fan 14 in the instantaneous coolant coolant 16, and instantaneous cooling including an ammonia oxide coolant is provided below. A case body 162 of the coolant 16 for the agent is arranged. A plurality of pipes 163 made of a copper material are erected and arranged in the case body 162. Each pipe 163 is filled with a coolant 164 containing about 20 to 70% ammonia nitrate. When the pull cord 161 a is pulled, water flows from the chemical reaction water container cassette 161 into the pipe 163 in the case body 162, and the flowed water causes a chemical reaction with the coolant 164 to cool the coolant 164. A gap 165 smaller than the diameter of the pipe 163 is formed between the pipes 163, and the outside air passes through the gap 165 while contacting the wall of the pipe 163 having a high thermal conductivity. As a result, the outside air is cooled by heat conduction from the wall of the pipe 163 and conveyed into the goggles 11 (see FIG. 1 or FIG. 2).

  A mesh 17 made of stainless steel and having fine eyes is attached to the air blowing downstream side of the coolant 16 for the instantaneous coolant. Wearing the mesh 17 having extra fine eyes prevents “cold temperature failure” when the face touches the cooling part directly, and the wind of the outside air introduction fan 14 introduced linearly. By passing through the mesh, it has the effect of being softly dispersed.

  In addition, as shown in FIG. 4, you may comprise the above-mentioned cooling ventilation unit 15 with the cooling ventilation unit 15A of another embodiment. The cooling air blowing unit 15A is disposed in the peripheral wall portion 112 of the goggle portion 11 shown in FIG. 1, and is placed in a water-filled container 152A at the upper portion of a case-like case 151A disposed on the front surface on the air blowing downstream side of the outside air introduction fan 14. The coolant storage case 153A having a peripheral wall portion formed in a V-shaped cross-section in a side view with respect to the flow direction of the outside air is disposed below the water sealing container 152A. The coolant storage case 153A is filled with a coolant 154A containing about 20 to 70% ammonium nitrate. A plurality of discharge holes 157A are formed in the side wall on the outside air discharge side of the case 151A, and the cooled outside air is discharged from the case 151A.

  A pull cord 156A is connected to, for example, a cellophane tape 155A, which is detachably attached to the water sealing container 152A. When the pull cord 156A is pulled, the cellophane tape 155A is peeled off, and water flows from the water sealing container 152A into the coolant storage case 153A to immerse the coolant 154A. The coolant 154A is cooled in a few seconds by reacting with water.

  The outside air flows from the case 151A by the outside air introduction fan 14 rotated by the operation of a push button switch (not shown), contacts the V-shaped peripheral wall portion of the coolant storage case 153A, and flows along the peripheral wall portion. Then, it is cooled by the coolant 154A and conveyed into the goggles 11 (see FIG. 1 or FIG. 2).

  Further, as shown in FIG. 1, a band 23 is fixed to the disaster prevention mask 10 of the embodiment so as to straddle a part of the peripheral wall portion 112 of the goggles portion 11 or the mask portion 12 from the back of the head. The band 23 is formed to be stretchable so that the goggle part 11 and the mask part 12 can be in close contact with the face.

  Next, the operation of the disaster prevention mask 10 according to the first embodiment configured as described above will be described with reference to FIGS.

  The disaster mask 10 is permanently placed in any room of the house. When a fire occurs, the disaster prevention mask 10 is worn around the wearer's face. As shown in FIG. 3, by pulling the pull cord 161a of the instantaneous coolant coolant 16 of the cooling air blowing unit 15, water flows from the chemical reaction water container cassette 161, and the coolant 164 of the instantaneous coolant coolant 16 performs a chemical reaction. Wake up and cool. Then, the fan push button switch 18 is pressed to drive the outside air introduction fan 14. Then, outside air is introduced and the outside air is filled in the goggle unit 11. In the outside air, smoke molecules are removed by the fan filter 13 having a carbon monoxide removing agent. The outside air is cooled by the cooling air blowing unit 15 as described above, and fills the goggles 11.

  On the other hand, when breathing, the outside air from which the smoke molecules are removed is sucked from the breathing port 22. Air exhausted by breathing is exhausted from the check valve exhaust port 21 to the outside. The pressure inside the goggles 11 is slightly higher than the outside pressure due to the introduction of outside air. Therefore, although toxic gas and toxic smoke try to enter the goggles 11 between the disaster prevention mask 10 and the face, they are blocked by high pressure and are difficult to enter.

  As time has passed since the occurrence of the fire, the fire has become intense in the room, generating toxic gas and toxic smoke, etc., filling the room. However, the wearer wearing the disaster prevention mask 10 can ensure visibility because the temperature inside the disaster prevention mask 10 due to the introduction of outside air does not rise and toxic gas and toxic smoke do not enter the goggles 11. The initial fire extinguishing work and the escape action can be quickly performed within a short time.

  As shown in FIG. 5, an external air introduction fan 14, a cooling air blowing unit 15 including an instantaneous coolant coolant 16 having a chemical reaction water container cassette 161, a battery 19 connected to the external air introduction fan 14 by wiring, and the like. These devices can be housed and placed in the housing case 24 on the upper surface of the goggles 11. In this case, a plate 114 on which the above-described devices are placed is formed on the upper surface of the goggles 11 so as to extend rearward from the front of the goggles 11. In this embodiment, the outside air introduction fan 14, the cooling air blowing unit 15, etc. are not arranged in the goggle part 11, so the goggle part 11 is configured with a wide space and the battery 19 is not arranged in the mask part 12. Therefore, the mask portion 12 can be configured with a wide space.

  Next, a hood-type disaster prevention mask 30 of the second embodiment will be described with reference to FIG.

  The disaster prevention mask 30 surrounds the periphery of the head except the front guard part 33 having the goggle part 31 covering the eye part and the mask part 32 covering the nose part and the mouth part, and the face where the front guard part 33 is arranged. The hood part 34 arrange | positioned in this.

  The front guard part 33 is disposed in the front part of the disaster prevention mask 30 and is formed in a single plate shape facing the face. The front guard part 33 has a goggle part 31 formed of a transparent resin material at the top and a mask part 32 formed in a cloth shape at the bottom. The hood part 34 is made of a heat-resistant material lined with a non-combustible cloth, and is formed so that it can be covered from the top by opening the lower part.

  The outside air introduction fan 14, the instantaneous coolant coolant 16, the cooling air blowing unit 15 including the mesh 17, and the battery 19 are arranged in a superposed manner in the ceiling portion of the hood portion 34. The outside air introduction fan 14 is connected to a silicone tube 35 piped at the rear of the hood portion 34 via the fan filter 13. The silicone tube 35 extends upward from below the hood portion 34, is bent forward around the upper portion of the hood portion 34, passes through the hood portion 34, and is connected to the outside air introduction fan 14. A fan push button switch 18 is mounted on one side of the hood 34. Further, the mask portion 32 is provided with a respirator 36 having an air inlet 361 disposed in the lower portion thereof, and an air pressure adjusting valve 371 is attached to a cylinder 37 filled with compressed air via a flexible hose 38. It is piped.

  Therefore, the outside air is introduced into the goggles 31 through the silicone tube 35 by covering the disaster prevention mask 30 and operating the fan push button switch 18. Due to the introduction of outside air, the atmospheric pressure in the goggle part 31 increases, so that toxic gas and toxic smoke from the outside are less likely to enter the goggle part 31. Moreover, the compressed air filled in the cylinder 37 can be sucked from the breathing mask 36 and the outside air is cooled by passing through the cooling air blowing unit 15, so that the disaster prevention mask is introduced by introducing the cooled outside air. The temperature in 30 does not rise. Therefore, visibility can be secured and initial fire extinguishing work and escape behavior can be performed quickly within a short time.

  As described above, in the disaster prevention mask 10 (or 30) of the embodiment, the outside air that has been smoke-removed by the outside air introduction fan 14 can be introduced into the goggles 11 (or 31). Therefore, in the goggles 11 (or 31) in which the atmospheric pressure has increased, the invasion of toxic gas and toxic smoke that tries to enter from the slight gap of the disaster prevention mask 10 (or 30) attached to the face is prevented. Moreover, since the outside air in the goggles 11 (or 31) is cooled by the cooling air blower unit 15, the temperature in the goggles 11 (or 31) is not high, and the goggles 11 (or 31) are clouded. It is possible to prevent the thirst and to secure the field of view. By ensuring visibility, an initial fire fighting procedure or an emergency escape can be attempted.
