Detailed implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] To further understand the content of the present invention, the present invention will be described in detail in conjunction with the accompanying drawings.

[0024] Combined with Figure 1 , a gas detection device with an anti-blocking air inlet includes a detection box 1 and a suction pipe 2 fixedly penetrating through one side of the air pump. One end of the suction pipe 2 is movably provided with a filtering component 3 for filtering dust.

[0025] The following further describes the present invention in conjunction with the embodiments.

[0026] Embodiment 1:

[0027] Please refer to Figures 2 - 6 , the filtering component 3 includes a filtering pipe 31, a filtering tank 32 opened on the inner wall of the filtering pipe 31, a first filtering hole 33 opened on the inner wall of the filtering tank 32, a first filtering cotton placed inside the filtering tank 32, a first connecting plate 34 movably arranged at one end of the filtering pipe 31, and a first filtering plate 35 fixedly connected to the inner side of the first connecting plate 34. The first filtering plate 35 is used to filter impurities such as dust in the air. The gas enters the inside of the filtering pipe 31 through the first filtering plate 35. The first filtering cotton is rolled into a barrel and placed inside the filtering tank 32. The first filtering cotton is convenient for increasing the filtering area. The larger filtering area is convenient for better capturing and filtering pollutants in the gas to improve the filtering efficiency inside the filtering tank 32.

[0028] A first locking bolt 341 is threadedly connected between the filtering pipe 31 and the first connecting plate 34. The first connecting plate 34 is fixed to the filtering pipe 31 through the first locking bolt 341. Remove the first locking bolt 341 to separate the first filtering plate 35 from the filtering pipe 31, which is convenient for cleaning the first filtering plate 35.

[0029] A first fixing ring 5 is fixedly connected to the outer surface of the air suction pipe 2. A limiting groove 51 is formed at one end of the first fixing ring 5. A limiting block 4 is fixedly connected to the outer surface of the filter pipe 31. A second fixing ring 41 is fixedly connected to the outer surface of the limiting block 4. The diameter of the limiting block 4 is equal to the diameter of the limiting groove 51, and the diameter of the first fixing ring 5 is equal to the diameter of the second fixing ring 41. When the limiting block 4 is fitted with the limiting groove 51, the first fixing ring 5 is in contact with the second fixing ring 41, and the filter pipe 31 is in contact with the air suction pipe 2, facilitating the flow of gas through the filter pipe 31 into the air suction pipe 2.

[0030] A second locking bolt 411 is threadedly connected between the first fixing ring 5 and the second fixing ring 41. The second fixing ring 41 is fixed to the first fixing ring 5 through the second locking bolt 411. By removing the second locking bolt 411, the first fixing ring 5 and the second fixing ring 41 can be separated, facilitating the separation of the air suction pipe 2 from the filter pipe 31, and thus facilitating the cleaning of the filter pipe 31.

[0031] A rubber washer 7 is placed inside the limiting groove 51. Rubber has good elasticity and resilience. Placing the rubber washer 7 inside the limiting groove 51 helps improve the sealing performance, ensuring good sealing during the operation of the device and preventing gas leakage.

[0032] A fixing groove 21 is formed at one end of the air suction pipe 2. A second connecting plate 6 is placed inside the fixing groove 21. A second filter plate 61 is fixedly connected to the inner side of the second connecting plate 6. A groove 611 is formed at one end of the second filter plate 61, and a second filter hole 612 is formed at the other end of the second filter plate 61. A second filter cotton is placed inside the groove 611. The diameter of the second filter plate 61 is equal to the inner diameter of the air suction pipe 2. The second filter cotton is placed flat inside the groove 611. After the gas is filtered by the second filter cotton, it enters the air suction pipe 2 through the second filter hole 612, facilitating the improvement of the filtering effect.

[0033] A protective cover 8 is sleeved on one end of the filter pipe 31 close to the first filter plate 35. When not in use, the protective cover 8 helps prevent external debris, dust, or other contaminants from polluting the first filter plate 35, reducing the risk of pollution and damage, and facilitating the extension of the service life of the device.

[0034] In the initial state, the first connecting plate 34 is fixed to the filter tube 31 by the first locking bolt 341. The limiting block 4 is fitted and connected with the limiting groove 51. The first fixing ring 5 is in contact with the second fixing ring 41. The filter tube 31 is in contact with the suction pipe 2. The second fixing ring 41 is fixed to the first fixing ring 5 by the second locking bolt 411. The second connecting plate 6 is placed inside the fixing groove 21. The second filter plate 61 is in contact with the inner wall of the suction pipe 2. When in use, the air pump inside the detection box 1 adsorbs the external gas through the suction pipe 2. The external gas first enters the inside of the filter tube 31 after being filtered by the first filter plate 35. The first filter cotton inside the filter tank 32 facilitates increasing the filtering area. The larger filtering area facilitates better capturing and filtering of pollutants in the gas, so as to improve the filtering efficiency inside the filter tank 32. The gas that has been filtered twice enters the suction pipe 2 and is filtered three times by the second filter cotton placed inside the groove 611 and then enters the detection box 1 for detection. When cleaning is required, take out the first locking bolt 341 to separate the first filter plate 35 from the filter tube 31, which facilitates cleaning the first filter plate 35 and at the same time facilitates replacing the first filter cotton. Take out the second locking bolt 411 to separate the first fixing ring 5 from the second fixing ring 41, which facilitates separating the suction pipe 2 from the filter tube 31, thereby facilitating cleaning the filter tube 31 and at the same time facilitating taking out the second filter plate 61 to replace the second filter plate 61.
