Technical Field

[0001] This utility model belongs to the field of air pollutant collection technology, and in particular relates to a suction gun for collecting ambient air pollutants. Background Technology

[0002] Air sampling guns typically utilize the principle of negative pressure, generating suction through a connected air extraction device to draw air into the sampling container or adsorption medium inside the gun. During this process, various components in the air, such as particulate matter and gas molecules, are collected for subsequent analysis and detection.

[0003] In order to distinguish and collect dust or pollutants of different sizes in the air when the suction gun is used to draw air, so as to facilitate subsequent analysis and detection, an ambient air pollutant collection suction gun was designed. The device uses an enlarged surface groove, which allows particles of different sizes to adhere to the surface of the filter tank and filter screen under the action of the filter tank and filter screen. At the same time, the limiting block and the pushing block can facilitate the disassembly and installation of the filter tank, so as to distinguish and collect dust or pollutants of different sizes in the air, so as to facilitate subsequent analysis and detection.

[0024] In the following description, embodiments of the ambient air pollutant collection suction gun of the present invention will be described with reference to the accompanying drawings.

[0025] Example 1:

[0026] Figure 1-6 This invention illustrates an embodiment of an ambient air pollutant collection gun, comprising: an enlarged groove 2 connected to the air collection tube of a collection gun 1; rectangular holes on both sides of the enlarged groove 2; a support groove 3 slidably connected to the inner cavity of the enlarged groove 2; a filter groove 4 slidably connected to the inner cavity of the support groove 3; through grooves on both sides of the support groove 3; telescopic rods 5 fixedly connected to the inner cavities of both through grooves; limit blocks 6 fixedly connected to the opposite ends of the two telescopic rods 5; and springs 7 welded between the limit blocks 6 and the inner walls of the through grooves. The surface of the limiting block 6 is slidably connected to the inner cavity of the rectangular hole. The left and right sides of the enlarged groove 2 are connected to the rectangular groove 8 through the rectangular hole. The inner cavity of the rectangular groove 8 is slidably connected to the pushing block 9. The front and rear sides of the inner wall of the rectangular groove 8 are fixedly connected to the limiting strip 10. The front and rear sides of the pushing block 9 are provided with limiting grooves. The surface of the limiting strip 10 is slidably connected to the inner cavity of the limiting groove. By setting the limiting strip 10, the pushing block 9 can be guided in a straight line during the sliding process, so that the pushing block 9 can slide more smoothly.

[0027] Example 2:

[0028] Figure 1-6This invention illustrates an embodiment of an ambient air pollutant collection gun, comprising: an enlarged groove 2 connected to the air collection tube of a collection gun 1; rectangular holes on both sides of the enlarged groove 2; a support groove 3 slidably connected to the inner cavity of the enlarged groove 2; a filter groove 4 slidably connected to the inner cavity of the support groove 3; through grooves on both sides of the support groove 3; telescopic rods 5 fixedly connected to the inner cavities of both through grooves; limit blocks 6 fixedly connected to the opposite ends of the two telescopic rods 5; and springs 7 welded between the limit blocks 6 and the inner walls of the through grooves. Connecting grooves 11 are provided on both the left and right sides of the inner cavity of the support groove 3. Connecting strips 12 are fixedly connected to both the left and right sides of the expanded groove 2. The surface of the connecting strips 12 is slidably connected to the inner cavity of the connecting groove 11. Through the cooperation of the connecting grooves 11 and the connecting strips 12, the filter 4 can be guided vertically during the sliding process in the inner cavity of the support groove 3, so that the filter 4 can slide smoothly. A force-assisting piece 13 is fixedly connected to the front side of the support groove 3. A filter screen 14 is slidably connected to the inner cavity of the expanded groove 2. The filter screen 14 is located behind the filter 4.

[0029] Working principle: When using this utility model, the user slides the filter tank 4 into the inner cavity of the support tank 3, and then places the filter screen 14 and the support tank 3 into the inner cavity of the expansion tank 2 in sequence. When the support tank 3 slides into the inner cavity of the expansion tank 2, the position of the support tank 3 is fixed by the action of the limiting block 6 and the rectangular hole. After the collection suction gun 1 draws in, the user squeezes the pushing blocks 9 on both sides to push the limiting block 6, which then causes the limiting block 6 to disengage from the inner cavity of the rectangular hole and slide into the inner cavity of the through groove, thereby ending the restriction on the support tank 3. At the same time, the user squeezes the lever 13 to pull the support tank 3 out of the inner cavity of the expansion tank 2, and then classifies the collected sample. This allows for the differentiation and collection of dust or pollutants of different sizes in the air, which is convenient for subsequent analysis and detection.

[0030] In summary, this ambient air pollutant collection suction gun, by squeezing the pushing block 9 to push the limiting block 6 out of the inner cavity of the rectangular hole, and simultaneously squeezing the lever plate 13 to pull the support groove 3 out of the inner cavity of the enlarged groove 2, can then classify the collected samples, thereby achieving the purpose of distinguishing and collecting dust or pollutants of different sizes in the air, so as to facilitate subsequent analysis and detection.
