Description

Technical Field

[0001] The utility model relates to the technical field of carbon dioxide detection, in particular to a carbon dioxide gas analyzer. Background Art

[0002] The carbon dioxide gas analyzer mainly uses infrared spectroscopy technology to measure the concentration of carbon dioxide in the air. Its principle is based on the infrared absorption characteristics of carbon dioxide molecules at a specific wavelength. The carbon dioxide concentration is calculated by measuring the attenuation of light intensity after absorption. Carbon dioxide is an important factor in plant photosynthesis. Appropriate carbon dioxide concentration can increase crop yields. Therefore, in agricultural planting and greenhouse control, carbon dioxide gas analyzers are used to detect carbon dioxide concentrations.

[0003] Regarding the above technical solution, there are the following defects in use: in fields such as agricultural planting, an analyzer is needed to detect the concentration of carbon dioxide gas. When charging the analyzer, the power plug is inserted into the charging port at an angle, which will cause the internal deformation of the charging port after multiple charging, resulting in the power plug becoming loose when inserted into the charging port during subsequent charging. Utility Model Content

[0004] The utility model provides a carbon dioxide gas analyzer which solves the problems raised by the above-mentioned background technology.

[0010] Infrared probe, installed on the surface of the tester, to analyze and detect carbon dioxide in the air;

[0011] The charging port is installed on the surface of the tester to provide power to the tester;

[0012] The limiting device is arranged on the surface of the tester to fix the power plug;

[0013] The protective device is arranged on the surface of the tester to protect the infrared probe.

[0014] Furthermore, the limiting device includes a slide groove, which is opened on the surface of the tester, and the inner wall of the slide groove is slidably connected to two sliders, the inner wall of the tester is rotatably connected to a bidirectional screw, and the bidirectional screw is threadedly connected to the two sliders, the surface of the slider is fixedly connected to a positioning plate, the surface of the positioning plate is fixedly connected to a splint, one end of the bidirectional screw is fixedly connected to a twist block, and the surface of the twist block is fixedly connected to an anti-slip sleeve.

[0015] Through the above technical solution, when the tester is charged, the clamp can fix the power plug, and the positioning plate can cover the charging port to prevent dust from accumulating in the charging port, thereby effectively improving the service life of the tester.

[0016] Furthermore, a round rod is fixedly connected to the inner wall of the tester, and the round rod is slidably connected to two positioning plates.

[0017] Through the above technical solution, the positioning plate and the bottom surface of the tester are moved in close contact, so that the positioning plate covers the charging port more closely.

[0018] Furthermore, a clearance groove is provided on the surface of the tester, and the size of the anti-slip sleeve is matched with the size of the clearance groove.

[0019] Through the above technical solution, the twist block and the anti-slip cover will not protrude from the tester body, making it difficult for the twist block to be accidentally touched.

[0020] Furthermore, a rubber pad is fixedly connected to the surface of the clamping plate.

[0021] Through the above technical solution, the friction force of the clamping plate on the power plug is improved, and the tightness of the clamping plates when they are fitted together can also be improved.

[0023] Through the above technical solution, by protecting the infrared probe, the tester can be prevented from being accidentally scratched when stored, which would cause the infrared light emitted by the infrared probe to be uneven.

[0024] Furthermore, a protrusion is fixedly connected to the inner wall of the tester.

[0025] Through the above technical solution, the baffle is limited after it rotates into the rectangular groove.

[0026] Furthermore, a sponge pad is fixedly connected to the inner wall of the baffle.

[0027] Through the above technical solution, there is no friction between the infrared probe and the baffle, thus preventing the baffle from causing damage to the infrared probe.

[0028] The above solution of the utility model includes at least the following beneficial effects:

[0029] The utility model provides a limit device and uses two clamping plates to position the power plug when the tester is charged, so that the power plug is located in the center when inserted into the charging port, thereby preventing the power plug from being inserted obliquely into the charging port and causing damage to the charging port, thereby improving the practicality of the tester to a certain extent.

[0030] The utility model provides a protective device so that when the tester is not needed, the baffle is covered on the infrared probe, thereby effectively preventing the infrared probe from being accidentally scratched and ensuring the accuracy of data when the tester is testing.
