Abstract

This article is a gas alarm that is mounted on a wall surface or the like to detect and notify a gas leak in a room, and has a box shape with a substantially rectangular shape when viewed from the front. As shown in the reference perspective view showing the names of each part, the front surface of the gas alarm of this article gently bulges toward the center of the front, and the upper right side of the front surface is a large number for sounding a gas leak with an alarm buzzer. A small hole is opened, and an alarm lamp is provided on the upper left side to indicate a gas leak. The alarm lamp also serves as a stop switch for stopping the alarm sound. On the other hand, a plurality of parallel slits for gas flow are opened on the two adjacent outer peripheral surfaces at the lower part, and these slits are arranged so as to be arranged in an L-shape in front view across the corners of the two outer peripheral surfaces. ing. Therefore, when the gas leaked in the room passes through the slit on the outer peripheral surface and is detected by the gas sensor (not shown) provided inside the gas alarm, the alarm buzzer sounds and the alarm lamp emits light. When the alarm lamp / stop switch is pressed, the alarm sound is stopped for a certain period of time.
