Description

Technical Field

[0001] The utility model relates to the technical field of gas detection, in particular to a pump-suction type portable composite multi-gas detector. Background Art

[0002] A gas detector is an instrument tool for detecting gas leakage concentration, including: portable gas detector, handheld gas detector, fixed gas detector, online gas detector, etc. Gas sensors are mainly used to detect the types of gases in the environment. With the development of gas detectors, they are generally equipped with multiple gas sensors that can detect different types of gases, and are more functional. However, each startup will cause all gas sensors to enter the working state, resulting in most sensors being useless, which not only wastes electricity, but also greatly reduces the life of the sensor; and dust is easy to enter the pipe mouth of a general pump-suction gas detector. Under the action of the pump adsorption force, it is easy to adhere to the sensor, resulting in reduced sensitivity of the sensor; and the outer shell of a general portable gas detector is mostly a rectangular or truncated cone structure, which is not convenient to hold and easy to slip from the hand.

[0003] The publication (announcement) number is CN213121311U, which discloses a pump-suction portable composite multi-gas detector, including a main body, an alarm light, a liquid crystal display, a battery, a main control chip, an infrared sensor, an electrochemical toxic gas sensor and a catalytic combustion sensor. The upper end of the main body is provided with an air inlet, the lower end of the main body is provided with an air outlet, the front side of the main body is provided with the liquid crystal display, the inner side of the main body is provided with the battery, one side of the battery is provided with the main control chip, one side of the main control chip is provided with the infrared sensor, one side of the infrared sensor is provided with the electrochemical toxic gas sensor, and one side of the electrochemical toxic gas sensor is provided with the catalytic combustion sensor. The pump-suction portable composite multi-gas detector provided in the utility model is similar to a mobile phone type, which is not only easy to operate but also convenient to carry. The device is provided with a rubber plug at the air outlet, which can close the pipe mouth when stored to prevent external dust from entering the detection instrument.

[0004] Although the above scheme makes the pump-suction composite multi-gas detector easy to operate and carry, the detector is exposed to the outside world as a whole when it is carried and placed. The relatively fragile LCD screen is easily damaged and affects its use. The equipment has general protection. It is placed in a conventional storage package box, and it is troublesome to call the limit of the detector. For this reason, we propose a pump-suction portable composite multi-gas detector.
