Waterproof gas detection device for intelligent toxicity detection and ventilation integrated equipment

The utility model discloses a waterproof gas detection device for intelligent toxicity detection and ventilation integrated equipment, which comprises a sensor module, a sampling gas chamber cover and a gas suction pump which are arranged in a sealed shell, and the sensor module is mounted on the sampling gas chamber cover. The sampling gas chamber cover performs gas sampling through a first waterproof ventilation valve mounted on the shell, and the gas suction pump is connected with the sampling gas chamber cover and discharges sampled gas through a second waterproof ventilation valve mounted on the shell. The waterproof gas sensor has a good waterproof function, does not influence the normal gas sampling performance of the gas sensor, can remarkably prolong the service life and improve the reliability, and is convenient to maintain. 本实用新型公开了一种用于智能测毒通风一体化设备的防水气体检测装置，包括设于密封外壳内的传感器模组、采样气室盖和吸气泵，所述传感器模组安装在所述采样气室盖上，所述采样气室盖通过安装在所述外壳上的第一防水透气阀进行气体采样，所述吸气泵连接所述采样气室盖，并通过安装在所述外壳上的第二防水透气阀进行采样气体的排放。本实用新型具有良好的防水功能，且不影响气体传感
