When the sampling bottle 25 located below the third threaded hole 24 takes water and reaches the preset water level under the action of the vacuum pump, the infrared water level sensor 800 will sense it, and the infrared water level sensor 800 will send a signal to turn off the vacuum pump 40, so that the working rod 5 can complete the sampling of the three sampling bottles in one sampling operation, so that the sampling work can be more convenient and quick.
