Embodiment Construction

[0042] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0043] image 3 It is an exploded perspective view of main parts of the inhalation unit mounted on the gas mask according to the present invention. Figure 4 is a cross-sectional view of an assembled suction unit according to the invention. Figure 5 It is a sectional view showing the installation of the respirator cartridge and the inhalation unit according to the present invention.

[0044] refer to image 3 , The gas mask according to the embodiment of the present invention includes a mask body 100, an inhalation unit 300, a respirator filter 320, an exhaust unit 150 and a connector, which will be described later.

[0045] The mask body 100 is worn on the user's face so as to cover the face. As shown in the figure, the mask body 100 has an installation hole 110 at a predetermined position. The installation hole 110 allows the puri...

Abstract

The present invention provides a respiratory unit for gas masks and a self- locking / unlocking device for a respirator cartridge mounted to the respiratory unit. The respiratory unit includes a support plate (353), which has airflow holes and is provided in the respiratory unit body, a first sealing member (330), which is provided on the support plate to cover the airflow holes, and a second sealing member (370), which is provided on the support plate around the first sealing member and is elastically supported by an elastic support unit (360). Furthermore, a first coupling part (560) and a second coupling part (580) are respectively provided on corresponding surfaces of one selected from the respiratory unit body and the respirator cartridge and a remaining one thereof, so that the respiratory unit body and the respirator cartridge are coupled to each other using the first and second coupling parts.

Description

technical field [0001] The present invention generally relates to a gas mask that is applied to the user's face to prevent polluted air from being directly inhaled into the user's respiratory organs, and more particularly, to a gas mask having an inhalation unit and an exhaust unit through which air is drawn from The suction unit and the exhaust unit suck in the mask body or discharge it from the mask body. Background technique [0002] Generally, a gas mask is used where noxious gas or the like is present, thereby preventing the user from inhaling the noxious gas. Such a gas mask includes a mask body made of soft rubber and transparent lenses arranged at left and right positions on the upper part of the mask body. The gas mask has an exhaust hole and at least one respirator filter mounting hole formed under the transparent lens at at least one of the left and right positions, and the respirator filter is mounted on the respirator On the installation hole of the filter ele...
