[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] A gas metering and detection device includes a display module, a sensor module, and a gas filtration module. An air inlet (10) is opened at the center of the lower end of the gas storage tank (4), with the same diameter as the inner diameter of the filter material (7), and it contacts and cooperates with the filter material (7) to achieve communication. A top plate (2) is provided at the upper end of the gas storage tank (4), and a circular hole is opened at the center of the top plate for installing and removing the filter material (7). A groove is opened around the circular hole, and the thickness of the groove is the same as the thickness of the top cover (3). The groove is threaded on the inner side, and it meshes with the thread on one side of the inner surface of the top cover (3). The gas filtration module can be removed and installed by rotation.

[0028] The display module consists of a display and a processor chip inside it. The display (1) is located on the outer surface of the top plate (2) of the gas storage tank. It is responsible for receiving and processing the signals emitted by the electrochemical sensor (8), calculating information such as gas concentration value through intelligent algorithms, and displaying the data detected by the sensor module. This makes it convenient for technicians to view and record gas metering detection data and monitor gas concentration in real time. The display (1) can be an LED display, an LCD display, etc. There are no restrictions on the type of display. The processor chip can be, for example, a 32-bit high-speed ARM chip of the SM32F103 series, or a DSP control chip.

[0029] The sensor module consists of two adaptively configured electrochemical sensors. The sensor (8) is inverted and placed on the inner surface of the top plate (2) of the gas storage tank, and reacts with the chemical gas in the gas storage tank (4). The pin part is connected to the processor in the display (1). Different numbers and types of sensors are set according to actual needs, such as methane gas sensor, carbon dioxide gas sensor, hydrogen gas sensor, etc.

[0030] The gas filtration module includes a top cover (3), an arc-shaped handle (11), a slide groove (5), a slider (6), and filter material (7). The top cover is a concave cylinder with an arc-shaped handle (11) on the top. The inner side is threaded, which meshes with the thread on the side of the top plate (2). The connection and separation between the top cover (3) and the top plate (2) are achieved by rotation. A soft rubber gasket is provided on one side of the top of the inner surface of the top cover (3) to avoid hard contact and friction when the top cover (3) and the top plate (2) rotate together, further enhancing the airtightness of the gas storage tank (4). The filter material (7) is a cylindrical hollow shape with an open bottom and a closed top. A slider (6) is provided at the top. The slider (6) has two I-shaped protrusions side by side.

After the filter material (7) is installed on the top cover (3) through the groove (5) and the slider (6), the hollow hole at the bottom of the filter material (7) is in contact with the air inlet (10) of the gas storage tank (4).

[0031] When using this device, the staff connects it to an external chemical reaction instrument and uses the device to measure and detect the gas produced by the chemical reaction. When the chemical gas enters the gas storage tank (4) through the inlet (10), it first passes through the gas filtration module to filter out impurities and excess moisture in the chemical gas, and then seeps into the gas storage tank (4) through the fine pores of the filter material. The electrochemical sensor (8) at the bottom of the top plate (2) reacts with the target gas and converts information such as concentration into an electrical signal for output. After obtaining the concentration information of the target gas, the processor chip in the display module controls the display (1) to display the concentration information of the target gas, so that technicians can record and operate it. After the gas filtration module filters the gas, it ensures that the service life of the electronic instrument will not be affected by moisture, while improving the sensitivity and accuracy of the electrochemical sensor to be tested.

[0032] When the filter material (7) needs to be replaced, the staff can remove the gas filter device by rotating the handle (11) on the top cover (3) of the gas filter device and then slide the filter material (7) to separate it from the groove (5) on the bottom surface of the top cover (3). After replacing the filter material (7), the filter material is installed in the same way by sliding block (6), and then the gas filter device is installed and inserted into the gas storage tank (4) by threaded hole. The gas filter module can be removed and installed by threaded hole to ensure good airtightness of the device and prevent leakage. It is also convenient for staff to operate and replace.
