Description

Technical Field

[0001] This utility model relates to the field of gas detection and analysis equipment technology, and in particular to a laser gas analyzer for analyzing gas concentration. Background Technology

[0002] The principle of a laser gas analyzer is mainly based on laser spectroscopy technology. By measuring the absorption, scattering, or transmission characteristics of a gas to laser light, it can achieve accurate analysis of the gas composition and concentration.

[0003] The working principle of a laser gas analyzer can be summarized in the following steps: A laser source generates a laser beam. The laser source is the core component of the analyzer, producing a laser beam of a specific wavelength. This laser beam is used to irradiate the gas to be tested. The gas absorbs the laser energy. When the laser beam irradiates the gas to be tested, the gas molecules absorb the laser energy. The degree of absorption by the gas molecules depends on factors such as the type and concentration of the gas, as well as the wavelength and intensity of the laser. Photoelectric conversion and signal processing follow. The laser signal, after being absorbed by the gas, is received by photoelectric conversion devices such as photodiodes and converted into an electrical signal. Concentration calculation and output occur when the signal processing system calculates the concentration of the gas to be tested based on the received electrical signal and pre-set gas absorption spectrum data.

[0004] Existing laser gas analyzers require connecting different gas cylinders to the analyzer when detecting the concentration of various gases. The current connection method primarily involves connecting the spiral head on the gas cylinder's flexible hose to the analyzer's inlet. This method requires frequent disassembly and reassembly, which is time-consuming and labor-intensive. Therefore, we propose a laser gas analyzer for analyzing gas concentrations to solve these problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a laser gas analyzer for analyzing gas concentration, including a gas analyzer body. The gas analyzer body is provided with a display screen and control buttons. On the side of the gas analyzer body away from the display screen and control buttons, there is an air inlet, an exhaust, and a power socket. An air inlet plug is also provided in the air inlet, and an air inlet hose is connected to the air inlet plug.

When the air intake plug is inserted into the air intake interface, at least part of the elastic fixing component in the air intake interface is embedded in the embedding groove, so that the elastic fixing component fixes the air intake plug after it is inserted into the air intake interface.

[0009] Preferably, the air intake interface includes an outer ring frame and an inner ring frame, and the air intake plug is inserted between the outer ring frame and the inner ring frame.

The elastic fixing component is set on the inner side wall of the outer ring frame of the air intake interface. The fixing ball is embedded in the insertion groove of the air intake plug under the action of the spring force, thereby realizing the fixing of the air intake plug.

[0013] Preferably, four elastic fixing components are provided and are symmetrically distributed within the air intake interface.

[0014] The above technical solution involves setting four elastic fixing components, which are symmetrically distributed inside the air intake interface, so that the air intake plug is firmly fixed inside the air intake interface.

[0015] Preferably, the end of the air intake plug near the air intake interface has a convenient inclined surface for insertion.

[0016] The above technical solution is adopted: the end of the air intake plug near the air intake interface has a convenient inclined surface for insertion, which makes it easy for the air intake plug to be inserted into the air intake interface.

[0017] Preferably, the sealing member includes a sealing gasket and a sealing ring, the sealing ring being embedded in the inner ring frame of the air intake port, and the sealing gasket being embedded in the end of the inner ring frame.

[0018] The above technical solution employs a sealing component comprising a sealing gasket and a sealing ring. The sealing ring is embedded in the inner ring frame of the air intake port, and the sealing gasket is embedded in the end of the inner ring frame, providing a double seal to ensure sealing performance.

[0019] Preferably, the outer surface of the sealing ring is an arc-shaped surface.

[0020] The above technical solution adopts the following: the outer surface of the sealing ring is arc-shaped, which facilitates the insertion of the air intake plug.

[0021] Preferably, the outer periphery of the sealing ring at least partially fits the inner wall of the air intake plug.

[0022] The above technical solution ensures the airtightness of the gas being tested by having at least a partial outer portion of the sealing ring fit against the inner wall of the air inlet plug.

[0023] Preferably, heat dissipation holes are also provided on both sides of the gas analyzer body.

[0024] The above technical solution involves heat dissipation holes on both sides of the gas analyzer body to dissipate heat from the operating gas analyzer.

[0025] Compared with related technologies, this utility model has the following beneficial effects:

The end of the inlet hose furthest from the inlet plug is connected to the gas tank to be tested. An elastic fixing component and a sealing component are provided between the inlet port and the inlet plug. When different gases need to be tested, the inlet plug is fixedly connected to the gas analyzer body via a plug-in connection, allowing the gas to be tested from the gas tank to be analyzed to be delivered into the gas analyzer body. The elastic fixing component ensures that the inlet plug is inserted into the inlet port and will not detach from it. The sealing component ensures the sealing of the connection between the inlet plug and the inlet port. Compared with the traditional screw connection, this application eliminates the need for cumbersome disassembly when testing different gases, thus improving the efficiency of multi-gas testing.
