[0027] Embodiment: please refer to Figures 1 to 7 According to the embodiments of the present application, a technical solution is provided: a sampling device for canned gas production, comprising a tank body 1, a sampling port 2 is formed in the outer peripheral side wall and communicates with the inside of the tank body 1; a guide column 3 is fixed in the tank body 1, a sampling cavity 4 is defined in the guide column 3, a sampling inlet hole 5 and a sampling outlet hole 6 are respectively formed in the guide column 3 and communicate with the sampling cavity 4; a sealing part 7 is movably sleeved on the guide column 3, the sealing part 7 is adapted to seal the sampling port 2 and seal the sampling outlet hole 6 when the sampling port 2 is sealed, a spring 8 is sleeved on the guide column 3, the spring 8 elastically abuts against the sealing part 7, a limiting part 9 is arranged on the sealing part 7 to limit the sealing part 7 from being abutted out of the tank body 1 by the spring 8; a sampling assembly 10 is used to abut against the sealing part 7 to expose the sampling outlet hole 6, and seal the sampling port 2 when the sealing part 7 is abutted into the tank body 1, the sampling assembly 10 sucks the gas in the tank body 1 through the sampling outlet hole 6 when the sampling port 2 is sealed.

[0028] The sampling device for canned gas production has the above structure. When a user needs to sample the gas in the tank 1, first, the user abuts the sampling assembly 10 against the sealing part 7, moves it into the tank 1, and thus exposes the sampling outlet hole 6. At this time, the sealing part 7 is immersed in the tank 1, and the sampling assembly 10 replaces the sealing of the sampling port 2, so as to ensure that the gas does not leak during sampling. When the sealing part 7 is completely pressed into the designated position, the sampling assembly 10 sucks and samples the gas in the tank 1 through the sampling outlet hole 6. After sampling is completed, the sampling assembly 10 is withdrawn, the spring 8 pushes the sealing part 7 back to the original position, and the sampling outlet hole 6 and the sampling port 2 are automatically closed, so as to ensure the sealing of the gas in the tank 1 and improve the sampling efficiency.

[0029] In the embodiment, the sampling assembly 10 comprises an abutting ring 11, a sealing ring 12, a sampling cylinder 13, a piston 14, a movable column 15, and a pipe body 16. The sealing ring 12 is fixed to the second end of the abutting ring 11, the sampling cylinder 13 is fixed to the second end of the sealing ring 12, the piston 14 is arranged in the sampling cylinder 13, the movable column 15 is movably penetrated through the sampling cylinder 13 and fixed to the piston 14. A sampling groove 17 is arranged on the inner circumferential side wall of the abutting ring 11, the two ends of the pipe body 16 are respectively communicated with the sampling cylinder 13 and the sampling groove 17, and the abutting ring 11 is movably penetrated through the guide column 3. When the user uses the sampling assembly 10, first, the abutting ring 11 is abutted to the sealing part 7 by holding the sampling cylinder 13, the sealing part 7 is pressed into the tank 1 by pushing the sampling cylinder 13, the sampling outlet hole 6 is exposed, and in this process, the sealing ring 12 ensures the sealing of the sampling port 2 to avoid gas leakage. When the abutting ring 11 moves to the position, the sampling groove 17 is aligned with the sampling outlet hole 6. At this time, the piston 14 is driven by the movable column 15 to generate negative pressure in the sampling cylinder 13, so as to suck the gas in the tank 1 into the sampling cylinder 13 through the sampling outlet hole 6.

[0030] In the embodiment, the first end of the abutting ring 11 is fixed with an abutting long ring 18, and the sealing part 7 is provided with an abutting groove 19 suitable for the abutting long ring 18 to be movably inserted. When the user uses the sampling assembly 10, first, the first end of the abutting ring 11 is aligned with the abutting groove 19 on the sealing part 7, so as to ensure that the abutting long ring 18 can be accurately inserted into the abutting groove 19 of the sealing part 7. With the advancement of the abutting ring 11, the abutting long ring 18 is inserted into the abutting groove 19, and the sealing part 7 is pushed to move inward by the applied pressure, so as to improve the stability during abutting.

[0032] In the embodiment, the sampling cylinder 13 is sleeved with a friction ring 22; when the user holds the sampling cylinder 13, the friction ring 22 sleeved on the sampling cylinder 13 increases the friction between the palm of the user and the sampling cylinder 13, so that the user can stably hold the friction ring 22.

[0033] In the embodiment, the abutting block 23 is fixed to the end of the movable column 15 away from the piston 14; when the user pulls the movable column 15, the abutting block 23 provides a fulcrum for the user to pull the movable column 15, so as to facilitate the user to pull the movable column 15.

[0034] Working principle: when the user needs to sample the gas in the tank 1, first, hold the sampling cylinder 13, make the abutting ring 11 abut on the sealing part 7, push the sampling cylinder 13, make the abutting ring 11 press the sealing part 7 into the tank 1, expose the sampling outlet hole 6, in this process, the sealing ring 12 can ensure the sealing of the sampling port 2, avoid gas leakage, when the abutting ring 11 moves to the position, the sampling groove 17 is aligned with the sampling outlet hole 6, at this time, the piston 14 is driven by the movable column 15 to generate negative pressure in the sampling cylinder 13, so as to suck the gas in the tank 1 into the sampling cylinder 13 through the sampling outlet hole 6, after sampling is completed, the sampling assembly 10 is withdrawn, the spring 8 pushes the sealing part 7 back to the original position, automatically closes the sampling outlet hole 6 and the sampling port 2, ensures the sealing of the gas in the tank 1, improves the efficiency of sampling operation; when the user uses the sampling assembly 10, first, the first end of the abutting ring 11 is aligned with the abutting groove 19 on the sealing part 7, ensures that the abutting long ring 18 can be accurately inserted into the abutting groove 19 of the sealing part 7, with the advance of the abutting ring 11, the abutting long ring 18 is inserted into the abutting groove 19, and through the applied pressure, the sealing part 7 is pushed to move inward, improves the stability in the abutting process; after the sealing sleeve 20 enters the sealing groove 21 on the tank 1, the sealing performance of the sampling assembly 10 to the sampling port 2 is further improved; when the user holds the sampling cylinder 13, the friction ring 22 sleeved on the sampling cylinder 13 increases the friction between the palm of the user and the sampling cylinder 13, so that the user can stably hold the friction ring 22; when the user pulls the movable column 15, the abutting block 23 provides a fulcrum for the user to pull the movable column 15, so as to facilitate the user to pull the movable column 15.
