Detailed Description

The objects, technical solutions and advantages of the present utility model will become more apparent by the following detailed description of the present utility model with reference to the accompanying drawings. It should be understood that the description is only illustrative and is not intended to limit the scope of the utility model. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present utility model.

The specific embodiment is as follows: referring to fig. 1-2, a gas leakage detecting device comprises an insulated shell 1, wherein a controller and a battery are arranged in the shell 1, a touch screen 2 is arranged on one side of the shell 1, the battery and the touch screen 2 are electrically connected to the controller, and a switch is further arranged on the shell 1. The utility model discloses a gas detection sensor, including casing 1, coiled pipe 3, shell 1, shell 41, gas detection sensor 44, shell 41 are provided with a plurality of through-holes 411 in the side that gas detection sensor 44 is close to casing 1, shell 41 is the opening in the side that gas detection sensor 44 kept away from casing 1, the one end that casing 1 was kept away from to coiled pipe 3 is provided with probe 4, probe 4 includes shell 41, shell 1 is provided with the gas detection sensor 44 with controller electric connection to coiled pipe 3 is the metal design hose, and it can keep its shape that it can be crooked into certain shape in the space, and the electric wire can pass from its inside. By bending the serpentine tube 3, the length of its forward extension can be adjusted and into some places of relatively tortuosity. In the process of extending the probe 4 to the detection position, if the probe 4 is displaced in the axial direction, air can easily flow through the probe 4 due to the through hole 411, so that the air at the position to be detected can be quickly contacted with the gas detection sensor 44, and the detection result at the position to be detected can be more quickly obtained.

Further, a fan 42 electrically connected to the controller is further disposed in the housing 41, the fan 42 is located at a side of the gas detection sensor 44 away from the housing 1, and when the fan 42 rotates, the air flow in the probe 4 can be promoted, especially when the axial displacement of the probe 4 is small, the air at the position to be detected can be rapidly introduced into the probe 4.
