[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4The utility model provides a technical solution: a fume sampling gun for environmental detection, comprising a gun body 1, a controllable discharge mechanism 2 is arranged at the left end of the gun body 1, a storage chamber 3 is provided inside the gun body 1, a smoke inlet hose 4 is fixedly connected to the upper surface of the gun body 1, a manual valve 5 is arranged on the smoke inlet hose 4, a piston 6 is slidably connected to the inner wall of the storage chamber 3, a limiting hole is arranged at the right end of the gun body 1, a push-pull rod 7 fixedly connected to the piston 6 is slidably connected to the inner wall of the limiting hole, a plurality of clamping holes 8 are equidistantly arranged on the surface of the push-pull rod 7, a locking mechanism 9 which cooperates with the clamping hole 8 is fixedly connected to the right end surface of the gun body 1, When sampling flue gas, by closing the manual valve 5 and pulling the push-pull rod 7, the piston 6 can be driven to slide to the right, so that the storage chamber 3 is in a negative pressure state, and then the locking mechanism 9 can be used to fix the push-pull rod 7 and the piston 6, and then the end of the smoke inlet hose 4 is extended into the oil fume gas, and the manual valve 5 is opened. At this time, the smoke will be sucked into the storage chamber 3, thereby effectively reducing the sampling time. After the smoke enters the storage chamber 3, the manual valve 5 is closed again to complete the oil fume gas collection work. Compared with the existing technology, the oil fume sampling gun does not require an external power supply and a built-in battery, is easy to use, and has improved applicability.

[0027] The locking mechanism 9 includes a fixed support plate 10, a spring 11, a latch rod 12 and a baffle plate 13. The fixed support plate 10 is fixedly connected to the side of the gun body 1, the latch rod 12 is slidably connected to the fixed support plate 10, the baffle plate 13 is fixedly connected to the outer surface of the latch rod 12, the spring 11 is sleeved on the outer surface of the latch rod 12, and the latch rod 12 can fit with the snap-in hole 8.

[0028] When the piston 6 moves to the leftmost side of the storage chamber 3, the latch rod 12 can fit with the rightmost snap-in hole 8. In the initial state, the latch rod 12 is inserted into the rightmost snap-in hole 8 to fix the latch rod 12. When the piston 6 moves to the leftmost side of the storage chamber 3, the gas in the storage chamber 3 can be emptied, effectively avoiding the problem of residual gas in the storage chamber 3 affecting subsequent oil fume gas detection.

[0029] The push-pull rod 7 also includes a limiting protrusion 14 integrally formed with the push-pull rod 7, and a volume scale value 15 is set on the limiting protrusion 14. By setting the limiting protrusion 14, the clamping hole 8 on the surface of the push-pull rod 7 can be limited so that the clamping hole 8 is always facing downward. By setting the volume scale value 15 and cooperating with the latch rod 12 to insert into different clamping holes 8, different volumes of oil fume gas can be collected, thereby realizing quantitative collection of oil fume.

[0030] A U-shaped snap-in plate 16 is fixedly connected to the upper surface of the gun body 1, and the U-shaped snap-in plate 16 can fit and snap-in with the smoke inlet hose 4. By providing the smoke inlet hose 4 and utilizing the free movement of the smoke inlet hose 4, smoke sampling can be performed at different locations, thereby improving the sampling convenience, and when not in use, the smoke inlet hose 4 can be snap-in and fixed using the U-shaped snap-in plate 16, thereby facilitating storage and carrying.

[0031] The controllable emission mechanism 2 includes a blocking disk 17, a plurality of smoke exhaust pipes 18 with different aperture sizes, a first magnet 19 and a second magnet 20. The blocking disk 17 is rotatably connected to the left end of the gun body 1 through a pin shaft. A smoke exhaust hole 21 is opened at the left end of the gun body 1. The smoke exhaust pipe 18 is fixedly connected to the surface of the blocking disk 17 in an annular array and is interconnected with the smoke exhaust hole 21. The first magnet 19 is fixedly connected to the surrounding of the blocking disk 17 in an annular array. The second magnet 20 is fixedly embedded in the left end of the gun body 1, and the first magnet 19 and the second magnet 20 are of opposite polarity. Corresponding to each other, by setting up a controllable emission mechanism 2, the first magnet 19 and the second magnet 20 are attracted to each other, so that the sealing disk 17 can be fixed easily. When the smoke exhaust pipe 18 is aligned with the smoke exhaust hole 21, the piston 6 is driven to move by pushing the push-pull rod 7, so that the oil fume gas in the storage chamber 3 can be discharged easily. By aligning the smoke exhaust pipes 18 with different apertures with the smoke exhaust holes 21, the smoke exhaust speed can be controlled easily. The through-hole rotating sealing disk 17 makes the smoke exhaust pipe 18 and the smoke exhaust hole 21 disconnected, so as to prevent the oil fume gas in the storage chamber 3 from overflowing.

[0032] Support legs are provided at the four corners of the lower surface of the gun body 1, and a handle 22 is rotatably connected to the side of the gun body 1. By providing the support legs, the sampling gun can be conveniently placed on a table or the ground, and by providing the handle 22, the sampling gun can be conveniently carried.

[0033] Working principle: When the oil fume sampling gun for environmental detection is in use, first close the manual valve 5, then pull down the latch rod 12, when the latch rod 12 is away from the clamping hole 8, the baffle plate 13 will compress the spring 11, and the push-pull rod 7 can move freely at this time. By pulling the push-pull rod 7, the piston 6 can be driven to slide to the right, so that the storage chamber 3 is in a negative pressure state, and then release the latch rod 12, and use the spring 11 to push the baffle plate 13, so that the latch rod 12 can be inserted into the clamping hole 8, thereby achieving the fixation of the push-pull rod 7 and the piston 6, and then extend the end of the smoke inlet hose 4 into the oil fume gas, and open the manual valve 5. At this time, the smoke will be sucked into the storage chamber 3, thereby effectively reducing the sampling time. When the smoke enters the storage chamber 3, the manual valve 5 is closed again to complete the oil fume gas collection work. Compared with the prior art, the oil fume sampling gun does not require an external power supply and a built-in battery, which is convenient to use and improves applicability.
