DETAILED DESCRIPTION

In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, rather than all the embodiments. The detailed description is as follows.

Please refer to Figure 1. The utility model provides a technical solution: a multifunctional combustible gas detection device, including a main box 1, a detection tube 2 is arranged in the main box 1, detection covers 3 are arranged at both ends of the detection tube 2, an electrochemical reaction tube 4 is arranged in the detection tube 2, an electrochemical sensor 5 is arranged in the electrochemical reaction tube 4, a semiconductor sensor 6 is arranged in the detection tube 2, and infrared sensor transmitting ends 7 and infrared sensor receiving ends 8 are arranged at both ends of the detection cover 3.

The electrochemical sensor 5 is a sensor that uses electrochemical principles to detect the concentration of a target substance. Its basic principle is to use the target substance to undergo an oxidation-reduction reaction with the electrode surface to generate a current or voltage signal, and to determine the concentration of the target substance by measuring the changes in these signals. The electrochemical sensor 5 is usually composed of a working electrode, a reference electrode, and a counting electrode. When the target substance undergoes an oxidation-reduction reaction with the surface of the working electrode, a current or voltage signal is generated. The size of this signal is proportional to the concentration of the target substance, so the concentration of the target substance can be determined by measuring the changes in the signal.

Semiconductor sensor 6 is a sensor commonly used for combustible gas detection. Its working principle is based on the interaction between semiconductor materials and target gases. When semiconductor materials are exposed to target gases, the target gases affect the conductive properties of the semiconductor materials, thereby producing changes in resistivity or voltage. By measuring these changes, the concentration of the target gas can be determined.

The principle of infrared sensor in combustible gas detection is based on the absorption characteristics of target gas to infrared radiation. When the target gas exists, it absorbs infrared radiation of a specific wavelength, and this absorption characteristic can be detected by the infrared sensor. Infrared sensors are usually used to detect some common combustible gases, such as methane, propane, butane, etc. Infrared sensors have some advantages in combustible gas detection, such as high sensitivity to some specific combustible gases, and not easily affected by moisture and temperature changes.

The three sensors work together to make up for shortcomings and provide applicable capabilities.
