The air ball valve 30 connected to the air inlet pipe 12 needs to receive the signal from the external pipe system to operate. And in the default state, the state is closed. The external pipe system detects the air pressure value inside the pipe through an external sensor. When the air pressure value in the pipeline reaches the set value, the signal is sent to the external air ball valve 30, the air ball valve 30 is opened, and the external air enters the device from the air inlet pipe 12.
An external pipeline system connected with the air outlet pipe 11 is mainly used for pumping the sample bottle in the emission position to the external pipeline system. The external piping system is equipped with a vacuum pump 32 for evacuating the interior of the piping to form a negative pressure environment.
After the sample bottle is in the in-place launching position, the outer sealing ring 24 on the end face of the sealing sliding sleeve 6 is extruded with the air inlet hole face at the bottom of the blanking turnover barrel 16, and sealing is achieved between the sealing sliding sleeve 6 and the blanking turnover barrel 16. A pair of inner sealing rings 28 and 29 are embedded in the inner wall of the sealing sliding sleeve 6 to realize the sealing between the sealing sliding sleeve 6 and the air inlet pipe 12.

The external pipe system, the inventive device and the air ball valve 30 form a closed pipe space.
After the operation is finished, the external pipeline system gives a signal to the vacuum pump 32, the vacuum pump 32 starts to vacuumize, the sensor of the external pipeline system detects the negative pressure condition inside the pipeline in real time, when the negative pressure value inside the pipeline reaches a set value, the sensor outputs a signal to the external air ball valve 30, the air ball valve 30 is opened instantly, and a pressure difference is formed between the inside and the outside of the pipeline. Air enters the pipeline through the air inlet pipe 12, and sample bottles in the blanking turnover barrel 16 are blown into the air outlet pipe 11 from the feed inlet of the blanking turnover barrel 16 through the air inlet hole at the bottom of the blanking turnover barrel 16 and then enter the external pipeline system. The sample bottles enter the designated area upon external tubing dispense. At this point, the sample vial launch is complete.
After the sample bottle launch is completed, the external air ball valve 30 is closed and the external plumbing vacuum pump 32 is stopped. According to the invention, the piston rods of the first thin cylinder 1 and the second thin cylinder 2 move to right to specify positions, so that the first push plate 7 is driven to move to the right, and the first push plate 7 drives the sealing sliding sleeve 6 to move to the right, thereby completing the resetting.
