[0002] Accurate detection of gas concentrations is crucial in numerous fields, including modern industrial production, environmental monitoring, and scientific research. During industrial production, many chemical reactions produce various gases. Timely and accurate monitoring of these gas concentrations not only affects production efficiency but is also closely linked to safe production and product quality. For example, in chemical synthesis, improper control of reaction gas concentrations can lead to runaway reactions and serious safety accidents; in the food processing industry, detecting gas concentrations inside packaging directly impacts the shelf life and quality of food.

[0003] However, current gas concentration detection devices on the market have revealed numerous problems in practical applications. On the one hand, the complex detection environment results in diverse gas compositions, making it difficult for conventional devices to handle mixed gases containing impurities, special properties (such as acidity and alkalinity), and high temperatures, severely impacting detection accuracy. On the other hand, traditional devices lack flexibility in controlling gas flow rate and direction, failing to meet the differentiated gas flow requirements of various detection scenarios, and the detection process is prone to interruption when the gas flow rate is unstable. Furthermore, existing devices have poor heat dissipation and complex installation and maintenance, increasing operating and time costs. Utility Model Content

[0025] Example

[0026] Reference Figure 1-4 This is an embodiment of the present invention, which provides a gas concentration detection device, including,

[0027] The air supply assembly 100 includes a bracket 101, a support plate 102 fixedly connected to the end of the bracket 101, a filter 103 fixedly connected to the end of the support plate 102, and an air pump 104 fixedly connected to the lower side wall of the bracket 101. The air outlet of the air pump 104 is connected to the air inlet of the filter 103 through a pipe.

[0028] The detection assembly 200 includes an adapter 201 fixedly connected to the middle position of the support plate 102, a valve 202 fixedly connected to one end of the adapter 201, a neutralization pipe 203 installed on one side of the adapter 201, a heat dissipation pipe 204 adapted to be installed on the side wall of the support plate 102, and a gas detector 205 fixedly connected to the middle position of the bracket 101. The other end of the adapter 201 is connected to the outlet of the filter 103 through a pipe. The side wall of the valve 202 is connected to one end of the heat dissipation pipe 204 through a pipe. The other end of the heat dissipation pipe 204 is connected to the inlet of the gas detector 205 through a pipe.

[0029] The support plate 102 is fixedly connected to the end of the bracket 101, providing lateral support and load-bearing capacity. It also serves as the mounting base for other components, including the filter 103 and some key components of the detection assembly 200, ensuring stable installation. The filter 103 filters the gas entering the device, removing impurities and particulate matter to ensure accurate test results. The air pump 104 draws in external gas, pressurizes it, and delivers it to the filter 103, thus driving the gas flow throughout the device and ensuring continuous detection. The valve 202 is fixedly connected to one end of the adapter 201 to control the gas flow. When the valve 202 is open, gas flows from the adapter 201 through the valve 202 into subsequent pipelines; when the valve 202 is closed, the gas passage is cut off, achieving precise control of gas flow. The neutralization pipe 203 neutralizes gases with special properties (such as acids and alkalis) to prevent corrosion or interference with subsequent detection components, ensuring the stability and accuracy of the detection. The heat dissipation pipe 204 is used to dissipate heat and cool the gas passing through the valve 202, so as to prevent the gas temperature from affecting the detection accuracy of the gas detector 205.

[0030] Specifically, the detection component 200 also includes fins 206 encapsulated on the sidewall of the heat sink 204, with the middle region of the heat sink 204 extending uniformly into the interior of the fins 206.

[0031] The fins 206 are used to increase the heat dissipation area to improve heat dissipation efficiency, further increasing the gas cooling efficiency, so that the gas can enter the gas detector 205 at a relatively stable temperature.

[0032] Furthermore, the detection assembly 200 also includes a cover plate 207 snapped onto the side wall of the heat sink 204, and a support rod 208 inserted into the side wall of the cover plate 207, with the end of the support rod 208 threadedly connected to the side wall of the support plate 102.

[0033] The cover plate 207 and the support rod 208 are used together to facilitate the installation and fixing of the heat dissipation pipe 204, and also to facilitate the disassembly and maintenance of the heat dissipation pipe 204 when needed.

[0034] Furthermore, the detection assembly 200 also includes a gas storage tank 209 fixedly connected to the middle position of the bottom of the bracket 101, with the end of the gas storage tank 209 connected to the side wall of the adapter 201 via a pipe.

[0035] Among them, the gas storage tank 209 is used to store a certain amount of gas, which can provide a stable gas source supplement at the initial stage of device startup or when the gas flow is unstable, ensuring the continuity of the detection process.

[0036] Preferably, an adjustment knob 210 is installed on the side wall of the adapter 201, the end of the adjustment knob 210 extends to the inner wall of the adapter 201, and the adjustment knob 210 is fixedly connected to the valve plate encapsulated inside the adapter 201.

[0037] The opening and closing angle of the valve plate inside the adapter 201 can be controlled by rotating the adjustment knob 210, thereby adjusting the flow rate and direction of the gas in the adapter 201.

[0038] It should be noted that the detection assembly 200 also includes a flow meter 211 fixedly connected to the side wall of the bracket 101. The flow meter 211 is installed in the middle of the pipe connecting the heat dissipation pipe 204 and the gas detector 205, and the flow meter 211 is used in conjunction with the gas detector 205.

[0039] Among them, the flow meter 211 is used to measure the gas flow rate entering the gas detector 205, providing flow data reference for gas concentration detection, which helps to analyze and calculate gas concentration more accurately.

[0040] Preferably, a pressure valve is installed at the outlet of the gas storage tank 209, and the pressure valve at the end of the gas storage tank 209 is connected to the adapter 201 through a pipeline.

[0041] The pressure valve controls the output pressure and flow rate of the gas in the gas storage tank 209, ensuring that the gas enters the adapter 201 smoothly.

[0042] In operation, when the gas concentration detection device starts working, the air pump 104 starts, drawing in and pressurizing external gas, which is then transported through a pipeline to the filter 103. The clean gas filtered by the filter 103 enters the adapter 201. At this point, the flow rate of the gas entering different branch paths can be adjusted by rotating the adjusting knob 210 to control the opening and closing of the valve plate inside the adapter 201, according to actual detection needs. If neutralization is required, some gas will flow through the neutralization pipe 203, and the neutralized gas will return to the adapter 201. The valve 202 is opened, and the gas flows from the adapter 201 through the valve 202 into the heat dissipation pipe 204. In the heat dissipation pipe 204, the gas is cooled by heat exchange with the fins 206. During the cooling process, the flow meter 211 measures the gas flow rate in real time as the cooled gas flows through the heat dissipation pipe 204. Finally, the gas enters the gas detector 205, which accurately detects the gas concentration and outputs the result based on the received gas flow data and its own detection principle. Throughout the process, the gas storage tank 209 can replenish gas in a timely manner through the gas pressure valve according to the gas pressure in the adapter 201, thereby maintaining the stability of gas flow.

[0043] In summary, filter 103 filters the incoming air, neutralization pipe 203 neutralizes special gases, heat dissipation pipe 204 cools the gas, and flow meter 211 provides flow data. The coordinated action of these multiple components effectively eliminates various interference factors, ensuring that gas detector 205 can accurately detect gas concentration and improve the reliability of detection results. The device possesses multiple gas processing functions, including filtration, neutralization, and heat dissipation, adapting to the detection needs of gases with different properties, broadening its applicability, and enabling it to handle complex and diverse gas detection scenarios. Adjusting knob 210 allows flexible control of the gas flow rate and direction within adapter 201, valve 202 precisely controls gas on / off, and gas tank 209 works in conjunction with pressure valve to maintain stable gas pressure. These designs provide the device with high flexibility and accuracy in controlling gas flow rate and direction, facilitating adjustments based on actual detection requirements. The heat dissipation pipe 204, combined with fins 206, increases the heat dissipation area, significantly improving heat dissipation efficiency and quickly and effectively reducing gas temperature, preventing excessively high gas temperatures from affecting detection accuracy.
