At the same time, the bottle mouth is embedded between the two sets of symmetrically distributed bottle mouth positioning clips 44, and reset through the operation panel 11. Then the weighing parameters are set and the diaphragm pump 2 is started. At this time, under the action of the diaphragm pump 2, the fluid passes through the filter tip 22, the suction pipe 21, the diaphragm pump 2, the liquid delivery pipe 61 in sequence, and is finally filled into the filling bottle by the filling head 6 until the set weighing parameter is reached.
