Abstract

The present invention relates to a gas leakage alarm case, and in particular, the front case and the lower end of the case is formed in a slightly smaller size than the front case to form a gas injection passage so that the gas inlet is formed on the rear of the case to prevent the ingress of water from the outside. It provides a waterproof gas leakage alarm case consisting of a rear case. In addition, the gas sensor chamber and the buzzer chamber are formed separately in the rear case where the gas sensor and the buzzer are mounted so that the gas flows smoothly into the sensor chamber and is not disturbed by the occurrence of the buzzer sound pressure. A window is provided in the part to provide a gas leakage alarm case which shows the light of the LED and prevents the penetration of water.

Description

A case of gas-leakage warning device in water resistance type}

The present invention relates to a waterproof gas leakage alarm case that can prevent the penetration of water from the outside.

Gas leakage alarm case 10 generally used in the present, as shown in Figure 1, the grate 12 is formed on the lower end of the front case 11 to facilitate the detection of the gas. Therefore, since the gas is introduced through the grate 12, the flow of the gas can be well sensed. In gas detection, LNG gas is used within 30cm from the ceiling, and LPG gas is used within 30cm from the floor. However, according to the case of the conventional gas leakage alarm, when detecting the LPG gas, the gas leakage alarm is installed on the bottom side, so when water is used to clean the floor, the water is inadvertently splashed or sprayed toward the alarm. Can lose. As a result, when water enters the gas leakage alarm, there is a problem that causes a malfunction such as a malfunction or an inoperable state.

The present invention to solve the problems of the prior art aims to provide a gas leakage alarm case that can prevent the penetration of water from the outside.

In order to achieve the above object, the present invention has a front case in which a hole for an LED is formed, and a rear side in which a circuit part including a gas sensor and a buzzer is formed in a size smaller than the front case so that a gas injection hole is formed at a lower end thereof. A gas leakage alarm case consisting of a case is provided. In addition, according to the gas leakage alarm case of the present invention, the gas sensor chamber and the buzzer chamber is formed in the rear case on which the gas sensor and the buzzer are mounted. In addition, according to the gas leakage alarm case of the present invention is formed in the hole structure in which the LED of the front case is inserted into the window structure. As a result, the penetration of water from the outside is blocked to prevent malfunctions such as malfunctions.

Such a gas leakage alarm case 20 of the present invention will be described in more detail below with reference to the accompanying drawings. As shown in the front view of the gas leakage alarm case 20 according to the present invention of Figure 2a, the front case 21 of the gas leakage alarm case of the present invention has two LED is inserted into the middle portion in the vertical direction A hole 23 is formed, and the window 25 covering these two holes into which the LED is inserted is formed, and there is no gas inlet such as a grate formed in the prior art as a whole, and water splashes from the outside. The penetration of water is also blocked. And, Figure 2b is a rear view of the gas leakage alarm case according to the present invention, as shown here, the rear case 24 has a lower end is formed slightly smaller than the front case 21 is coupled to the front case When the gas injection hole 26 is formed in the lower portion of the back. In addition, as shown in FIG. 2B, the gas sensor chamber 27 and the buzzer chamber 28 are separately formed at the lower end of the rear case 24 on which the circuit unit including the gas sensor and the buzzer is mounted. Thereby, the gas sensor chamber 27 allows the introduced gas to move well in the airflow, and minimizes the disturbance from the buzzer sound pressure when detecting the gas leakage.

According to the gas leakage alarm case of the present invention of the above configuration, the front case with a hole for inserting the LED, and the lower end is formed of a smaller size than the front case and comprises a rear case for forming a gas injection passage, In the rear case including the gas sensor and the buzzer, the gas sensor chamber and the buzzer chamber are separately formed, and the hole for inserting the LED forms a transparent window, thereby preventing the ingress of water from the outside to prevent the gas leakage alarm. While preventing malfunctions or malfunctions, the flow of gas to be sensed is also smoothed and the buzzer negative pressure minimizes the obstacles to the sensor.

Claims (1)

In the gas leakage alarm case combined the front case with the LED insertion hole and the rear case with the blocking wall, The rear case has a smaller size than the front case to form a gas inlet, and the LED insertion hole is a waterproof gas leakage alarm case, characterized in that the transparent plate formed.
