Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of gas-sensitive sensors, and in particular relates to a gas-sensitive sensor for poison gas detection. Background Art
[0002] The gas sensor for poisonous gas detection is a sensor device specially used to detect specific toxic gases in the air. It uses chemical and physical effects to convert gas composition and concentration into electrical signal output, thereby realizing the detection and measurement of toxic gases. The working principle of the gas sensor may involve multiple mechanisms, such as chemical reactions, physical adsorption, and changes in wave velocity and frequency on the surface of acoustic wave devices.
[0003] The gas sensors currently on the market have the following problems when used:
[0004] 1. In the actual use of traditional gas sensors, the working stability and accuracy of gas sensors are easily affected by environmental factors. For example, changes in temperature, humidity and gas concentration may cause deviations in sensor readings. In an environment with high humidity, the performance of some gas sensors may be significantly reduced. Therefore, gas sensors cannot effectively dry out the moisture in the surrounding environment when in use;
[0005] 2. In actual applications, most gas sensors often have an integrated shell and mesh cover, which are used to filter attachments in the air. However, after long-term use, the air outside the mesh cover can easily cause blockage, and it is inconvenient to clean. The mesh cover cannot be disassembled well during application.

[0027] In order to better understand the purpose, structure and function of the utility model, the gas sensor for poison gas detection of the utility model is further described in detail below with reference to the accompanying drawings.
[0028] like Figure 1-4 As shown, a gas sensor for poison gas detection of the utility model comprises a base 1, a lower shell 5 is arranged on the top of the base 1, and since the base 1 is installed, it is convenient to install the lower shell 5 on the top of the base 1, the interior of the lower shell 5 is fixedly connected to a frame 14, the top of the frame 14 is connected to a reinforcement ring 19, a drying sheet 15 is arranged inside the frame 14, a notch 16 is arranged outside the lower shell 5, a push plate 17 is embedded inside the notch 16, and the push plate 17 is at the bottom of the drying sheet 15. By arranging the frame 14, the reinforcement ring 19, the drying sheet 15, the notch 16 and the push plate 17 inside the sensor, it is convenient to dry the humid environment and improve the drying effect of the humid environment of the gas sensor.
[0029] An upper shell 4 is provided on the top of the lower shell 5, a groove 10 is provided on the top of the upper shell 4, a ring body 9 is embedded in the groove 10, a mesh cover 13 is provided inside the ring body 9, a magnetic rod 11 is provided at the bottom of the ring body 9, a metal sleeve 12 is provided at the bottom of the upper shell 4, and the magnetic rod 11 is inserted into the metal sleeve 12. By arranging the mesh cover 13, the ring body 9, the groove 10, the magnetic rod 11 and the metal sleeve inside the upper shell 4, the mesh cover 13 can be quickly disassembled and assembled, which is convenient for the staff to clean the mesh cover 13.
[0030] An internal threaded barrel 7 is provided at the top of the lower shell 5, and an external threaded ring 6 is provided at the bottom of the upper shell 4. The internal threaded barrel 7 is threadedly connected to the external threaded ring 6. Due to the internal threaded sleeve and the external threaded ring 6, the lower shell 5 and the upper shell 4 can be easily disassembled and assembled.
[0031] An extension plate 18 is provided inside the frame 14 , one side of the extension plate 18 is connected to the push plate 17 , and the extension plate 18 is provided inside the notch 16 . The installation of the extension plate 18 makes it more convenient to push the push plate 17 .
[0032] The outer part of the upper shell 4 is provided with protrusions 8, which are distributed in a ring shape. By installing the protrusions 8, it is more convenient to screw the upper shell 4.
[0033] Inside the lower housing 5, there is a sintered body 3. Outside the sintered body 3, there are pins 2. The pins 2 penetrate through the base 1. Due to the presence of the sintered body 3, the sintering degree of the material can be measured more effectively.
[0034] The working principle of the gas-sensitive sensor for gas detection: When using this gas-sensitive sensor, first, the sensor body needs to be moved to a specified position. The user holds the base 1 and moves it. After moving to the specified position, the base 1 is placed on a plane. When the installation environment is relatively humid, a drying device needs to be installed inside first. By providing structures such as a frame 14, a reinforcing ring 19, a drying sheet 15, a notch 16, a push plate 17, etc. inside the sensor, first turn the upper housing 4 at the top of the lower housing 5 to take out the external thread ring 6 inside the internal thread cylinder 7. At the same time, there is a reinforcing ring 19 at the top of the frame. Then, the staff installs the drying sheet 15 inside the frame, so that the humid environment can be dried. Then turn the upper housing 4 to close it. However, when the effect of the drying sheet 15 weakens, first turn the external thread ring 6 at the bottom of the upper housing 4 in the reverse direction. Then, the staff pushes the push plate 17 inside the notch 16 to take out the drying sheet 15 and replace it with a new drying sheet 15. This can improve the drying effect of the gas-sensitive sensor on the moisture in the surrounding environment. Secondly, after using the mesh cover 13 for a long time, a large amount of dust adheres to the holes inside the mesh cover 13, which easily affects the gas detection. By providing structures such as a mesh cover 13, a ring body 9, a groove 10, a magnetic attraction rod 11, a metal sleeve 12, etc. inside the upper housing 4, first take out the upper housing 4 from the top of the lower housing 5. Then take out the ring body 9 from inside the groove 10. Then move the magnetic attraction rod 11 out of the metal sleeve 12. In this way, the mesh cover 13 can be quickly disassembled and assembled, which is convenient for the staff to clean the mesh cover 13. After the cleaning is completed, insert the magnetic attraction rod 11 into the metal sleeve 12. In this way, the ring body 9 can be embedded inside the groove 10, and thus the installation can be completed. The installation and disassembly are relatively simple during use.
[0035] It can be understood that the present utility model is described through some embodiments.
