Description

Dust mask with amplifying device {dustproof mask with apparatus for amplifing sound signal}

The present invention relates to a dust mask provided with a speech amplification device.

In general, a dust mask is a mask used to prevent inhalation of dust suspended in the air. Dust masks can be worn and used to prevent silicosis or pneumoconiosis in dusty workplaces, ie mines, quarries and the like. Such a dust mask is equipped with a special filter to prevent dust and is designed to prevent intake efficiency.

In such a dust mask, a filter body through which air mixed with dust is filtered is installed on one side of a mask body that blocks a user's nose and mouth, and an exhaust body through which internal air is discharged is installed on the other side of the mask body. When the air is inhaled by respiration, air mixed with dust may be supplied through the filter body in a filtered state, and may be discharged to the outside through the exhaust body at the time of discharge.

Conventional dust mask can improve the working environment as the user can be supplied dust-free air to the filter medium in the workplace with a lot of dust, it is possible to prevent the introduction of dust that can harm the health of the user.

However, in the case of the dust mask, it is difficult for the user to transmit a voice signal for various work instructions or communication during the work as it blocks the passage of dust, so that the dust is mixed when the voice is delivered with the mask body removed. When the compressed air is introduced into the mask body when the voice signal is transmitted, there is a problem in that the user inhales harmful dust together with the inhalation of contaminated air, thereby impairing the working environment.

In addition, when the voice signal is transmitted while dust is inhaled, it is difficult for the user to pronounce the voice signal accurately due to the mixed environment of the dust, and it is difficult to properly communicate the voice signal due to the difficulty in generating the voice signal. . In particular, the need for a device for transmitting a voice signal is increasing as a dangerous signal may be generated during operation or a voice signal correcting the wrong operation, and an accident may occur when the signal is incorrectly delivered.

Accordingly, a user wearing a normal dust mask proceeds to the doctor through a hand signal, but the meaning is difficult to be clearly transmitted compared to the voice, and if the doctors do not communicate with each other, loss and accidents are caused by incorrect work. There was a problem.

In recent years, a voice amplification apparatus that amplifies a user's voice inside a mask body to be generated outside is used. Such a voice amplification device has a microphone installed inside the front portion of the mask body for generating sound, a speaker installed toward the outside of the front portion of the mask body, amplifies the voice generated from the microphone to the outside, and a howling generated from the speaker. An amplifier circuit and a power supply are installed to reduce the howling phenomenon.

However, the dust mask equipped with the conventional voice amplification device has a microphone, amplification circuit, a speaker, and a power supply respectively installed in the front of the mask body worn by the user, so that the weight is heavy at the front position when the user wears the mask. It is difficult to wear, and even after wearing, the weight acts unevenly on the front side, so there is a problem in that it is inclined to the front side and peels off when moving.In addition, the amplification circuit installed outside the microphone body is connected to the power supply and supplied power Since the circuit is provided to amplify the signal input from the microphone, the amplification circuit body is exposed to the contaminated air in which dust is mixed, and there is a problem that the circuit is damaged by the dust. That is, as dust is deposited on the surface of the amplifying circuit body in which power is supplied and operated, there is a problem in that the supplied power is damaged due to a short circuit or a fire caused by the dust.

In addition, the speaker located in front of the mask body has to have a structure in which the cover is opened so that sound can be emitted as the sound amplified to the outside can be installed in the sealed structure of the amplification circuit installed with the speaker. There was a problem that is damaged by the external impact or inflow of polluted air.

The problem to be solved of the present invention by arranging other parts on the rear in addition to the essential parts that generate the voice of the voice amplification device to amplify the voice generated inside the dust mask to prevent the inflow of dust during breathing to the outside By dividing the weight, it is possible to provide a dustproof mask provided with a voice amplification device in which the wearing efficiency is improved and the weight is divided even when moving to prevent the mask from being peeled off.

In the anti-vibration mask having a voice amplification device installed according to an embodiment of the present invention, the anti-vibration mask is mounted on the user's face to breathe in an environment contaminated with dust, and provided in a form mounted on the user's face. Outside air is sucked when breathing, the face body for discharging the air to the outside after inhalation, is disposed on both sides of the outer surface of the face body, a filtration filter for filtering the air sucked, is disposed on the back of the face body, A fixed body which is connected to the face body and is installed to be worn by the user, is disposed on an inner front side of the face body, a microphone that signals and transmits the user's voice, and is disposed on the front center of the outside of the face body Speaker, which emits voice with the received voice signal, of the fixed body An amplifier circuit connected to the microphone and the speaker to amplify the voice signal, and a power supply unit disposed at one side of the fixed body and connected to the amplifier circuit to supply power.
