Description

Technical Field

[0001] The utility model relates to the technical field of sampling equipment, in particular to a bladder sampler. Background Art

[0002] A crucial step in the ventilation process during daily production is displacement sampling. This requires ignition with a bladder, and a yellow flame is considered acceptable. Currently, a standard bladder is used for sampling. After sampling, the hose must be manually bent 180° to seal the bladder and prevent gas from escaping. During the ignition test, the hose must be returned to the bladder to allow the gas to escape.

[0003] However, the sampling port and ignition port of the traditional bladder sampler are set at the same end, which makes sampling inconvenient and easily leads to sampling failure due to gas leakage during the sampling process, affecting the efficiency of gas detection.

[0004] A Chinese patent with publication (announcement) number CN117109991A discloses a sealer and a gas sampler, which includes a top cover and a base, an inlet and an outlet, a snap-fit ​​assembly and a sealing assembly. The top cover and the base are arranged relative to each other in a first direction, the top cover is rotatably connected to the base around the first direction, and the inner wall surface of the top cover and the inner wall surface of the base jointly define an inner cavity; the inlet and the outlet are arranged relative to each other in a second direction and are both connected to the inner cavity, the snap-fit ​​assembly is arranged in the inner cavity and is connected to the base, the snap-fit ​​assembly includes a slot, and the slot, the inlet and the outlet are arranged in sequence in the second direction to form a channel; the sealing assembly is arranged in the inner cavity; the top cover has an opening position and a sealing position, in the opening position the trachea can pass through the channel and the airflow in the trachea can flow normally; in the sealing position the trachea passes through the channel, and the top cover rotates relative to the base around a preset angle in the second direction so that the sealing assembly bends the trachea.

[0005] The sealer and gas sampler involved in the above patents still have some obvious shortcomings in actual use. The sampler is also inconvenient to use, so we need to propose a bladder sampler. Utility Model Content
