Description

Mask for air respiration {omitted}

The present invention relates to an air breathing mask, and more particularly, to an air breathing mask in which a device for communication is added to a mask worn by a firefighter, a soldier, a diver, and the like.

In order to extinguish a fire, firefighters do not inhale toxic gases by wearing a mask for breathing air, and the mask is connected to a reservoir on the back and an air supply pipe to breathe air from the reservoir.

Similarly, the masks used for soldiers' long-term CBR operations are similarly structured to receive air from a backed tank. In particular, divers wear masks to cover the front part of their face for long underwater work. Is supplied with a hose to breathe.

By the way, such a mask is usually a device for breathing does not have a separate communication equipment is not a smooth communication with colleagues.

For example, if an accident occurs because a firefighter can't inform a colleague at a location where there is a danger such as collapse during firefighting, fire accidents often occur.

In addition, in military operations or underwater operations, there is always a risk of inefficiency or accidents due to lack of communication.

Therefore, the present invention is to add a communication device having a microphone and a speaker in the air breathing mask for the air breathing to make a smooth communication with a nearby colleague or a remote control panel during fire suppression, military operations, underwater work It is a task to provide a mask.

In order to solve the problem,

Masks worn on the head, and breathing air from the outside through the air supply pipe.

A communication terminal installed in a mask and connected to a radio by a wire,

A microphone installed inside the mask and connected to a communication terminal,

It is composed of a speaker module that is branched from the communication terminal through the speaker wire, and mounted near the wearer's ear by the mounting portion installed in the mask,

Speaker module

A groove-shaped speaker accommodating part is formed, and a case accommodating the speaker is provided. Inside the speaker accommodating part, a speaker wire is introduced from the outside and connected to the speaker, and an inlet of the speaker wire is filled with epoxy to maintain airtightness. In the open part of the accommodating part, the air-breathing mask of the present invention is configured so that the diaphragm is covered while maintaining airtightness.

By this configuration, the present invention is effective in preventing accidents and efficient work by making a smooth communication with a nearby colleague or a remote control panel, and also has an effect that can be used underwater because the speaker exposed to the outside is waterproof.

1 is a view showing a mask structure for breathing air of the present invention.
Figure 2 shows an exploded structure of the sputter module.
Figure 3 is a cross-sectional view showing a coupling structure of the speaker module.

The present invention will be described with reference to the drawings.

The mask 100 is worn on the front of the face, and has a structure that covers the eyes, nose, and mouth, and a large face lens 110 is formed at the eye area to monitor the external environment.

The strap 120 installed at the rear of the mask 100 may be tightened to fit the size of the head of the wearer in the form of an elastic band, and serves to keep the mask 100 and the face tight.

Positive pressure regulator 130 is installed in the front portion of the mask 100, it is connected to the air bag carried on the wearer's back through the air supply pipe 140 to receive the high-pressure compressed air to the pressure of the air that the wearer can breathe Will be adjusted.

In addition, the mask 100 is equipped with a communication terminal 150 for voice communication with a fellow or remote control panel, such a communication terminal 150 is a radio connection jack 190 is connected to the radio connection wire (connected to the radio connection jack ( Connected to the radio via 210.

In addition, the PTT switch 200 is installed in the radio connection wire 190 to control the transmission and reception of the radio.

That is, when the PTT switch 200 is pressed, transmission through the radio is possible, and if not pressed, the reception state is maintained.

The microphone 160 is installed inside the mask 100 to be connected to the communication terminal 150. The microphone 160 is preferably located as close to the mouth of the wearer as possible.

In addition, the speaker module 170 connected to the speaker wire 180 from the communication terminal 150 is mounted, such a speaker module 170 is mounted on the outer side of the mask 100 to be located near the wearer's ear ( The speaker wire 180 is mounted on the 181 to form a suspended shape.

This will expose the ear in order to quickly determine the situation of the scene when the mask 100 is worn, the speaker module 170 can not be accommodated inside the mask 100, and must be exposed to the outside. Even if a speaker is worn by inserting it into the speaker, it is best to hang the speaker so that it is located near the ear.

The mounting portion 181 for mounting the speaker wire 180 is formed of a wire receiving portion 182 in a tubular shape, one side of the wire receiving portion 182 is bonded, sewn, strap ( 120) will be mounted in the form of fixing with a tie band.

The speaker module 170 is configured to maintain airtightness as shown in FIGS. 2 and 3, wherein the speaker 177 is accommodated in the speaker accommodating part 172 formed in a groove shape in the case 171 of a hard synthetic resin material or a metal material. The upper part of the diaphragm 178 is covered to keep the airtight and at the same time to transmit the vibration from the speaker 177 to the outside as well as waterproof and explosion-proof is possible.

For this structure, the case 171 is provided with a speaker accommodating portion 172 having a circular groove shape, and the diaphragm seating jaw 176 is formed in a ring shape along an edge thereof.

At this time, the diameter of the speaker receiving portion 172 is preferably similar to the diameter of the speaker 177, it is preferable that the speaker 177 is mounted without shaking, and also the outside of the diaphragm seating jaw 176 is the same as the outer peripheral surface of the diaphragm 178. Is formed so as to support the edge of the diaphragm 178 is bonded to each other by bonding to maintain the airtight.

Of course, the case 171 may be installed to be hermetically installed by providing a packing member at the edge of the diaphragm 178 instead of bonding.

The diaphragm 178 may complement the strength by inserting a mesh inside the injection molding with synthetic resin material so as not to be deformed by water pressure and heat while transferring the vibration generated from the speaker 177 well.

In addition, in order to connect the speaker wires 180 to the speaker 172 accommodated in the speaker accommodating part 172 while maintaining airtightness, a groove-type epoxy filling part 173 is separately formed, and the epoxy filling part 173 is The wire inlet hole 174 is formed in communication with the outside of the case 171, the wire inlet hole 175 in communication with the inside of the speaker receiving portion 172 is formed on the other side.

Therefore, the speaker wire 180 is introduced from the outside of the case 171 through the epoxy filling part 173 through the wire inlets 174 and 175 to the speaker receiving part 172 and then connected to the speaker 177. By filling the epoxy filling unit 173 with epoxy, the speaker wires 180 are fixed, and the speaker receiving unit 172 is isolated from the outside of the case 171 to maintain airtightness.

Subsequently, when the diaphragm 178 is covered, the speaker 177 is completely inside the case 171 while keeping the airtightness, thereby preventing the speaker 177 from being damaged by heat or water pressure.
