The invention relates to a sampling unit for the concentrates preparation device. The unit comprises a movable rod, a sampling chamber, a sampling bore, an axle sleeve and an isobaric chamber. The movable rod is provided with a refreshing passage, and the tail end of the refreshing passage extends away from the handle and extends to the exterior cylindrical surface of the movable rod; the tail end of the refreshing passage is inside the sampling chamber when the sampling bore is inside the sampling chamber; the tail end of the passage is inside the axle sleeve and near to the back surface of the axle sleeve when the sampling bore is inside the axle sleeve and near to the front surface of the axle sleeve. Because concentrates in the sampling bore is refreshing in real time, it is no need to fast rotate the hand firstly when taking samples of concentrates in the boiler, it is convenient and time-saving. <Figure 8> |
