Description

Technical Field

[0001] This utility model belongs to the technical field of air pollution detection equipment, and specifically relates to an air pollution detection instrument. Background Technology

[0002] Air contains pollutants, and air pollution detection requires the use of gas detectors to measure and analyze the concentration of pollutants in the air. There are many types of gas detectors used for air pollution detection, and pump-suction gas detectors are one type of instrument. The LY-GD2000 model gas detector has a built-in sampling pump. The main structure of the gas detector includes a main unit with a display screen and operation buttons, a built-in pump base, and an air inlet pipe. It can be used to detect gases such as carbon monoxide, hydrogen sulfide, oxygen, and combustible gases by drawing air through the gas pump. When the gas detector is in use, the gas to be tested enters through the inlet pipe, which is exposed and unprotected. The accumulation of particulate matter will affect the detection accuracy. The built-in pump base and inlet pipe are unprotected and easily damaged. In addition, the outer shell is easily damaged when dropped, which will damage the internal circuits and components. The gas detector has no protective design on the shell and needs to be improved. Existing gas detectors have the problem of being easily damaged due to the lack of protective design on the housing, internal pump base, and air inlet pipe when detecting gases. Therefore, this application proposes an air pollution detection instrument. Summary of the Invention

The air pollution detection instrument of this application is model LY-GD2000. The built-in pump base 12 has a built-in sampling pump. The detector main unit 1 has a display screen and operation buttons. When detecting air gases, the instrument is turned on by operating the buttons on the detector main unit 1. The gas to be tested is sampled by the air pump inside the built-in pump base 12, and enters the detector main unit 1 from the air inlet pipe 11. It can be used to detect gases such as carbon monoxide, hydrogen sulfide, oxygen, and combustible gases. A protective sleeve 2 is fitted on the outside of the air inlet pipe 11 and the built-in pump base 12 to protect the air inlet pipe 11 and the built-in pump base 12, preventing damage to them and also preventing... Particulate impurities entering the air inlet pipe 11 can cause blockage or affect gas purity, reducing measurement accuracy. The housing protection assembly includes a fixedly connected back panel 6 and protective plate 4, a connecting strip 7 that is pulled and connected to the back panel 6, a sealing ring 3 that is sleeved on the outside of the protective sleeve 2 and fixed to the connecting strip 7 with screws, and a rotating component. The back panel 6 and protective plate 4 are fixed to the housing of the detector main unit 1 with screws. The back panel 6 and protective plate 4 are used to protect the housing of the detector main unit 1 and prevent damage to the housing and its internal components if the detector main unit 1 is dropped. The rotating component includes a fixed shaft 61 installed inside the back panel 6 and a support plate 5 that is rotatably sleeved on the outside of the fixed shaft 61. The support plate 5 can be opened around the fixed shaft 61 to support the tilted detector main unit 1. The detector main unit 1 can be placed on a flat surface, freeing the hands during long-term handheld operation and providing a support function.

[0016] In this embodiment, the protective sleeve 2 includes a pump cylinder a sleeved on the outside of the built-in pump seat 12 and a sleeve b sleeved on the outside of the air inlet pipe 11. The surface of the sleeve b is provided with an air hole 21. When the sealing ring 3 slides and the air hole 21 is exposed, the inside and outside of the protective sleeve 2 are connected, which facilitates the gas to enter the air inlet pipe 11 and does not affect the pumping sampling.

[0017] In this embodiment, the sealing ring 3 is sleeved on the outside of the sleeve b. The inner diameter of the sealing ring 3 is the same as the outer diameter of the sleeve b. The sealing ring 3 is sleeved on the protective sleeve 2 and blocks the air hole 21, so that the protective sleeve 2 can be blocked and external particles are prevented from entering the air inlet pipe 11.

[0018] In this embodiment, the end of the connecting strip 7 inserted into the back panel 6 is an inverted "T" shaped structure. The surface of the connecting strip 7 and the opposing surface of the support plate 5 are matched. A movable groove is provided on the surface of the back panel 6. The connecting strip 7 is located in the movable groove. One end of the connecting strip 7 serves to limit the support plate 5 and prevent the support plate 5 from flipping.

[0019] In this embodiment, symmetrically distributed magnetic metal rings 62 are fixedly connected to the outer side of the fixed shaft 61. A magnetic ring 51 is embedded on the opposite surface of one side of the support plate 5. The magnetic ring 51 and the corresponding magnetic metal ring 62 are fixed by magnetic adsorption. The magnetic ring 51 and the magnetic metal ring 62 are fixed by magnetic adsorption, which has the function of fixing the support plate 5 and preventing the support plate 5 from easily flipping over.

[0020] In this embodiment, a hanging hole c is provided on the surface of the support plate 5. There are two hanging holes c, one circular and the other square. When the support plate 5 is open, it is easy to hang it on the outside of the rod or pipe, thus having a hanging function.

[0021] Working principle and usage process of this utility model: When the LY-GD2000 gas detector detects air gases, operate the button on the main unit 1 of the detector to turn on the instrument. The gas is sampled by the air pump inside the built-in pump base 12. The gas to be tested enters the main unit 1 of the detector from the air inlet pipe 11. It can be used to detect gases such as carbon monoxide, hydrogen sulfide, oxygen and combustible gases. Manually move the connecting bar 7 upward. The connecting bar 7 moves the sealing ring 3 upward, and the air hole 21 is exposed. The inside and outside of the protective sleeve 2 are connected, which facilitates the gas to enter the air inlet pipe 11 and does not affect the pump suction sampling. The back panel 6 and the protective plate 4 are used to protect the housing of the detector main unit 1 to prevent damage to the housing and internal components after the detector main unit 1 is dropped. Manual operation: The support plate 5 rotates around the fixed shaft 61 to open the support plate 5, so that the support plate 5 supports the tilted detector host 1. The detector host 1 can be placed on a flat surface, freeing the hands from fatigue during long-term hand operation, and has the function of a support. When not detecting gas, the connecting strip 7 blocks the support plate 5 to prevent the support plate 5 from easily flipping over. The sealing ring 3 covers the vent 21, and the protective sleeve 2 is fitted on the outside of the air inlet pipe 11 and the built-in pump seat 12 to protect the air inlet pipe 11 and the built-in pump seat 12, to prevent damage to the air inlet pipe 11 and the built-in pump seat 12, and to prevent particulate impurities from entering the air inlet pipe 11, causing blockage or affecting gas purity and reducing measurement accuracy. In summary: The gas detector of this application has protective designs on its housing, built-in pump base 12 and air inlet pipe 11. The back panel 6 and the protective plate 4 are used to protect the housing of the detector main unit 1 to prevent damage to the housing after the detector main unit 1 is dropped, which would cause damage to its internal components. The protective sleeve 2 is used to protect the air inlet pipe 11 and the built-in pump base 12 to prevent damage to the air inlet pipe 11 and the built-in pump base 12, and to prevent particulate impurities from entering the air inlet pipe 11.
