The present invention relates to a multi-function mask, more specifically, the field of view of the wearer in the field of fire extinguishing, as well as in the industrial field of handling the fire and the toxic gas difficult to secure the visibility by night or smoke The present invention relates to a multifunctional mask having forest fire extinguishing and a voice amplifier function used in industrial sites, which can enable communication while securing a digital signal.

In general, the flame retardant mask is provided with a purifying means for shielding the wearer's mouth and nose and in communication with the interior to purify the smoke and toxic gas flowing from the outside.

Therefore, in the industrial fire extinguishing site in the field of fire extinguishing fire, or to protect the wearer from the smoke or toxic gas from the outside to prevent the wearer's choke can secure the wearer's safety.

In recent years, there has been provided a flame retardant mask further comprising not only a purifying means but also a voice transmitting means for transmitting the wearer's voice to the outside.

For example, a "multifunctional mask" (hereinafter, referred to as a conventional flame retardant mask) of the Republic of Korea Patent Application No. 2005-58109 is known, a conventional flame retardant mask is provided between the elastic hair band and both ends of the hair band. A mask body worn on the face, a cylindrical purifying body provided on both sides of the mask body so as to communicate with the inside, and purifying smoke and toxic gases; Characterized in that it comprises a voice amplification means provided to amplify and deliver the voice of.

The voice amplification means may include a case in which a plurality of through holes are formed at the front and a part of which protrudes outwardly of the mask body, and a microphone provided to convert a wearer's voice into an electrical signal inside the case; An amplifying circuit board for outputting the electrical signal as an amplified control signal, a speaker connected to the amplifying circuit board to convert the control signal into a voice signal, and outputting the voice signal, the speaker, the amplifying circuit board, and the lighting means. Power supply means for selectively supplying power by operation switch operation, and a waterproof member provided between the speaker and the plurality of through holes.

Therefore, the mask body has a voice amplifying means that protrudes to the outside to amplify the wearer's voice to the outside to have the advantage of smooth communication.

However, the following problem occurs when using the flame-retardant mask configured as described above.

First, since the voice amplification means provided in the mask body protrudes forward, a phenomenon in which the case constituting the voice amplification means collides with the surrounding structure frequently occurs in an evolutionary or industrial site. Therefore, the voice amplification means is easily damaged due to the collision between the voice amplification means and the structure.

In addition, the voice amplification means includes a weight chain case, thereby weighting the flame retardant mask. Therefore, when the fire is extinguished or the work is performed while wearing a heavy weight mask, the wearer can easily feel fatigue, and a lot of power is required to move the face wearing the mask. It had a problem of degrading.

Therefore, the present invention was invented to solve the above problems, and by amplifying the voice while forming the front of the mask body on a flat surface, as well as fire extinguishing such as wildfire, the front and the structure of the mask in the industrial site An object of the present invention is to provide a multifunctional mask that can prevent damage to the amplification means due to the collision in advance.

In addition, there is also an object to reduce the weight of the mask to minimize the weight of the mask by reducing the weight of the mask by providing various components constituting the voice amplification means in the mask body to the minimum.

Another object of the present invention is to provide a multifunctional mask in which a purification body is also recessed inside the mask body to prevent a collision phenomenon caused by an external protrusion of the purification body in advance.

The present invention for achieving the above object is worn on the face through the hair band provided in the rear, and the front is provided with a component mounting portion recessed or penetrated, and one side or both sides is provided with toxic gas purification means communicating with the inside. A voice amplification means including a mask main body, a plurality of components provided in the component mounting portion to amplify the voice and emanating to the outside, and amplified in the front of the component mounting portion so that only the voice is generated by the voice amplification means. And a cover portion covering the front of the means.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
