If a reagent is added into each bottle, an action cycle needs to be completed within 60mS, the currently adopted method is a solenoid valve or a pump mode, because one cycle of a solenoid valve actuating mechanism is larger than 60mS, only a whole row of multiple filling heads can be adopted for matching a production line, for example, the production line stops, 10-20 filling heads fill simultaneously, 10-20 products flow simultaneously after filling is finished, the production line stops waiting in the process, and the production speed is reduced. In another conventional method, the reagents are filled continuously at the position where the product flows through the production line, when the bottle mouth moves to the filling port, the reagents enter the bottle, and the reagents flow out of the filling port and flow into the production line in the middle of the bottle, so that most of the reagents are wasted, and the bottle and the production line are required to be cleaned.
