Example

[0021] like Figure 1-Figure 3 As shown, a telescopic sampling rod accessory for odor sampling comprises a handheld part 1 and a sampling mechanism, wherein the sampling mechanism comprises a three-section telescopic hollow rod 2, wherein the three-section telescopic hollow rod 2 is arranged at the top end face of the handheld part 1, wherein a dust block 3 is arranged at the top end face of the three-section telescopic hollow rod 2, wherein a dust net 31 is arranged inside the dust block 3, wherein the diameter of the dust net 31 is 0.85 times of the minimum inner diameter of the three-section telescopic hollow rod 2, wherein a rubber ring 32 is arranged at the bottom end face of the dust block 3, wherein the rubber ring 32 is movably connected to the inner side of the three-section telescopic hollow rod 2, wherein a disassembly assembly is arranged at the connection between the dust block 3 and the three-section telescopic hollow rod 2; wherein the disassembly assembly comprises an external threaded ring 21, wherein the external threaded ring 21 is arranged at the outer side of the three-section telescopic hollow rod 2, wherein an annular enclosure 33 is arranged at the bottom end of the dust block 3, wherein the annular enclosure 33 is sleeved on the outer side of the three-section telescopic hollow rod 2, wherein an internal threaded ring 34 is arranged inside the annular enclosure 33, wherein the internal threaded ring 34 is threadedly connected to the external threaded ring 21;

[0022] Air pollution generally refers to the phenomenon that certain substances enter the atmosphere due to human activities or natural processes, present sufficient concentrations, reach sufficient time, and thus endanger human comfort, health and welfare or the environment. In the face of environmental and air pollution, it is necessary to effectively detect these polluted air;

[0023] The existing samplers are large in size and inconvenient to carry. Secondly, when the on-site environment is relatively bad, or in areas that are difficult to access, such as suspected leakage points or relatively narrow locations, other tools are needed to collect the odor, which increases the collection cost.

[0024] First, the three-section telescopic hollow rod 2 is a telescopic hollow cylindrical rod made of rolled metal material, which is characterized in that the metal strip is pre-shaped into an elastic curling layer with a memory function that is smaller than the outer diameter of the rod body, so that it has a self-tightening function, so that the curling layer always has elastic potential energy to apply pressure to the telescopic rod. When in use, the specific length of the three-section telescopic hollow rod 2 can be adjusted according to specific collection requirements, and the odor is collected along the three-section telescopic hollow rod 2, and the coarse particles in the air will be filtered out by the dustproof net 31 in the dustproof block 3. When the entire device needs to be maintained, the dustproof block 3 is rotated to separate the internal thread ring 34 from the external thread ring 21, and the dustproof block 3 can be removed. In normal use, the rubber ring 32 can ensure the sealing between the dustproof block 3 and the three-section telescopic hollow rod 2, and there will be no leakage points.

[0025] When it is necessary to place large sampling equipment in some narrow and difficult-to-place places, this device can be used instead. The three-section telescopic hollow rod 2 can be telescoped to ensure the flexibility of use of the device and collect air at different heights without changing the equipment. At the same time, the dustproof block 3 can filter coarse particles larger than one hundred microns to a limited extent, ensuring the normal use of the device.

[0026] In other embodiments, the present embodiment discloses, please Figure 3 As shown, anti-slip grooves 35 are equidistantly provided on the outside of the dust block 3, and the outer diameter of the rubber ring 32 is matched with the minimum inner diameter of the three-section telescopic hollow rod 2. Through this design, when the dust block 3 needs to be rotated, it is more convenient to apply force, and there will be no slipping when applying force, and the matching setting of the rubber ring 32 and the three-section telescopic hollow rod 2 can better ensure the sealing.

[0027] In other embodiments, the present embodiment discloses, please Figure 1-Figure 2 As shown, anti-skid grooves 11 are provided at equal distances on the outside of the hand-held portion 1, and anti-skid protrusions are provided at equal distances on the outside of the hand-held portion 1. Through this design, when the staff holds the device, the friction between the hand-held portion 1 is increased, thereby avoiding falling off during collection. Example

[0028] In other embodiments, the present embodiment discloses, please Figure 1 , Figure 4As shown, it also includes a fixing mechanism, which includes a connecting hose 4, which is plugged into the bottom end of the handheld part 1 and is connected to the three-section telescopic hollow rod 2. A fixing ring block 12 is provided on the bottom end face of the handheld part 1, and an insertion groove 13 is provided inside the fixing ring block 12. One end of the connecting hose 4 is movably connected to the inner side of the insertion groove 13, and a movable groove 14 is provided inside the insertion groove 13. A spring 15 is provided inside the movable groove 14, and a fixing pressure block 16 is provided on the other end face of the spring 15. One end of the fixing pressure block 16 is located inside the insertion groove 13 and is tightly pressed against the outer side of the connecting hose 4; the fixing pressure block 16 is located inside the movable groove 14, and a connecting rod 18 is provided on the other end face, and one end of the connecting rod 18 passes through the fixing ring block 12, is located outside the fixing ring block 12, and is fixedly connected to an outer pull plate 19;

[0029] First, pull the outer pull plate 19 outward, the connecting rod 18 moves back with the fixed pressure block 16 and squeezes the spring 15. The spring 15 contracts and the position of the insertion slot 13 is completely vacated. Then the connecting hose 4 is inserted into the handheld part 1 and connected to the handheld part 1. Then, release the outer pull plate 19, the spring 15 extends and pushes the fixed pressure block 16 into the insertion slot 13 to fix the connecting hose 4. The connecting hose 4 connected to the bottom end of the handheld part 1 can be fixed to avoid disconnection when the odor is transmitted to the sampling barrel, thereby better ensuring the smooth use of the sampling mechanism.

[0030] In other embodiments, the present embodiment discloses, please Figure 1 , Figure 4 As shown, an anti-slip pad 17 is provided on the end face of one end where the fixed pressure block 16 is connected to the connecting hose 4, and four fixed pressure blocks 16 are provided in a ring shape around the inner side of the fixed ring block 12; through this design, the performance of the fixing mechanism can be enhanced, thereby improving the friction between the connecting hose 4 and the fixed pressure block 16, and also improving the connection tightness between the connecting hose 4 and the hand-held part 1.

[0031] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
