[0025] Example 1

[0027] In this embodiment, the filter cartridge 301 is connected to the sampling device via the slider 311. During sampling, the sampling personnel hold the telescopic handle 1 and start the micro motor 302 to drive the fan blade 303 to rotate. The rotating fan blade 303 draws gas into the filter cartridge 301. The protective plate 313 is connected to the filter cartridge 301 via the nut 314 to protect the internal components of the filter cartridge 301. At the same time, the protective plate 313 can filter larger impurities in the gas entering the filter cartridge 301, preventing larger impurities from entering the filter cartridge 301 and damaging the internal components. The screw 307 connects the second annular plate 306 and the first annular plate 304 to the filter plate 301. 5. The filter plate 305 is fixed in place to further filter the gas entering the filter cartridge 301, avoiding excessive impurities in the sample that would make sample detection difficult. The limiting frame 308 is connected to the rotating rod 309 to support the rotating rod 309.

[0028] Example 2

[0029] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the sampling mechanism 2 includes a protective shell 201, a connecting seat 202 fixedly connected to the side of the protective shell 201, the connecting seat 202 being fixedly connected to the telescopic handle 1, a sealing plate 203 fixedly connected to one end of the protective shell 201, a cover plate 204 rotatably connected to the inside of the side of the protective shell 201, a baffle 205 fixedly connected to the inside of the other end of the protective shell 201, a sliding groove 206 provided on the inner side of the other end of the protective shell 201, the sliding groove 206 cooperating with the slider 311, and an observation hole 207 provided on the top surface of the sealing plate 203. An internal rotating shaft 208 is rotatably connected. One end of the rotating shaft 208 is rotatably connected to the inside of the baffle 205, and the other end of the rotating shaft 208 is fixedly connected to a turntable 209. A fixing nut 210 is threadedly connected to the top surface of the turntable 209. A rotating cylinder 211 is fixedly connected to the side of the rotating shaft 208. The side of the rotating cylinder 211 has four mounting slots 212, which are evenly distributed on the side of the rotating cylinder 211. A return spring 213 is fixedly connected to both sides inside the mounting slot 212. A retaining plate 214 is fixedly connected to one end of the return spring 213. The retaining plates 214 are in pairs, and a sampling tube 215 is movably connected inside each pair of retaining plates 214.

[0030] In this embodiment, the protective housing 201 is opened by pulling the cover plate 204 to rotate relative to the protective housing 201. Pulling the two clamping plates 214 separates them, causing the return spring 213 to contract. The sampling tube 215 is placed between the two clamping plates 214, and then the plates are released. The return spring 213 relaxes, causing the two clamping plates 214 to move and clamp the sampling tube 215. Similarly, according to sampling requirements, a corresponding number of sampling tubes 215 are connected to the clamping plates 214. The sealing plate 203 and the baffle 205 are connected to the rotating shaft 208 to support the rotating shaft 208 for sampling. During operation, the rotating disk 209 drives the rotating shaft 208 to rotate. The rotating shaft 208 is connected to the rotating cylinder 211, which in turn drives the rotating cylinder 211 to rotate. The rotating cylinder 211 drives the sampling tube 215 to rotate through the return spring 213 and the clamping plate 214. The position of the sampling tube 215 can be observed through the observation hole 207. When the sampling tube 215 rotates to be horizontal with the observation hole 207, the rotating disk 209 is stopped and the fixing nut 210 is rotated. One end of the fixing nut 210 abuts against the sealing plate 203 to restrict the rotation of the rotating disk 209, thereby fixing the position of the sampling tube 215 and facilitating the storage of gas by the sampling tube 215.

[0031] Example 3

[0032] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, a fixing ring 216 is fixedly connected to one side of the sampling tube 215, and a magnetic suction plate 217 is rotatably connected to the side of the fixing ring 216.

[0033] In this embodiment, the sampling tube 215 is connected to the magnetic plate 217 by the fixing ring 216 to seal the sampling tube 215, preventing impurities from entering the sampling tube 215 when it is not in use. When the sampling tube 215 is storing sampled gas, the magnetic plate 217 can be pulled to rotate relative to the fixing ring 216 to open the sampling tube 215, facilitating the storage of sample gas. After the sampling tube 215 has completed sampling the gas, the magnetic plate 217 can be pulled to rotate relative to the fixing ring 216 to seal the sampling tube 215, preventing the sample gas in the sampling tube 215 from flowing out. At the same time, it can also prevent external gas from entering the sampling tube 215 and mixing with the sample gas in the sampling tube 215, thereby affecting the detection results of the sample gas.

[0034] The working principle of this environmentally friendly gas sampling device will be explained in detail below.

[0035] like Figure 1-5As shown, by pulling the cover plate 204 to rotate relative to the protective shell 201, the protective shell 201 is opened. Pulling the two clamping plates 214 separates them. When the clamping plates 214 separate, they cause the return spring 213 to contract. The sampling tube 215 is placed in the two clamping plates 214, and the two clamping plates 214 are released. The return spring 213 relaxes, causing the two clamping plates 214 to move and clamp the sampling tube 215. The fixing ring 216 connects the sampling tube 215 and the magnetic suction plate 217 to seal the sampling tube 215, preventing impurities from entering the sampling tube 215 when it is not in use. According to the sampling requirements, the corresponding number of sampling tubes 215 are connected to the clamping plates 214, and the slider 311 is connected to the slide groove 206. The filter cartridge 301 is then connected to the protective housing 201. During sampling, the sampling personnel hold the telescopic handle 1 and rotate the turntable 209, which drives the rotating shaft 208 and the rotating cylinder 211 to rotate. The rotating cylinder 211 drives the sampling tube 215 to rotate through the return spring 213 and the clamping plate 214. The position of the sampling tube 215 can be observed through the observation hole 207. When the sampling tube 215 rotates to be horizontal with the observation hole 207, the rotation of the turntable 209 is stopped and the fixing nut 210 is rotated. One end of the fixing nut 210 abuts against the sealing plate 203 to restrict the rotation of the turntable 209, thereby fixing the position of the sampling tube 215. Pulling the magnetic suction plate 217 to rotate relative to the fixing ring 216 will move the sampling tube 215. When pipe 215 is opened, the micro motor 302 is started, driving the fan blade 303 to rotate. The rotating fan blade 303 draws gas into the filter cartridge 301. The protective plate 313, connected to the filter cartridge 301 by the nut 314, protects the internal components of the filter cartridge 301. At the same time, the protective plate 313 can filter larger impurities in the gas entering the filter cartridge 301. The screw 307 connects the second annular plate 306 and the first annular plate 304 to fix the filter plate 305. The filter plate 305 further filters impurities in the gas entering the filter cartridge 301. The limit bracket 308 connects to the rotating rod 309 to support the rotating rod 309. The output shaft of the micro motor 302 is connected to the rotating rod 309 to drive the rotating rod 309. 9. Rotating rod 309 connects to cleaning brush 310, which drives the cleaning brush 310 to rotate and clean the filter plate 305. This prevents excessive impurities on the surface of the filter plate 305 from clogging the filter holes on the filter plate 305, thus affecting the filtration rate of the filter plate 305. The filtered air can be discharged from the filter cartridge 301 through the connecting pipe 312 and enter the sampling tube 215. After the sampling tube 215 completes the sampling of the gas, it pulls the magnetic suction plate 217 to rotate relative to the fixing ring 216 to seal the sampling tube 215. This prevents the sample gas in the sampling tube 215 from flowing out and also prevents external gas from entering the sampling tube 215 and mixing with the sample gas in the sampling tube 215, thereby affecting the detection results of the sample gas.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
