[0024] As a preferred technical solution of the present invention, a method for using an auxiliary metering device for preparing a multivitamin injection comprises the following steps:

[0025] Step 1: The driving motor rotates forward through the driving shaft to drive the mixing mechanism and the infusion mechanism to operate synchronously. At this time, the ratchet set at the bottom of the driving shaft will be disengaged, that is, the first ratchet and the second ratchet will be disengaged; at the same time, the driving shaft will also drive the first sprocket and the first bevel gear to operate, so that the first sprocket drives the second sprocket and the stirring shaft to rotate through the chain, so that the stirring shaft drives the stirring rod and the scraper to rotate inside the mixing chamber to mix the liquid;

[0026] Step 2: The second bevel gear and the peristaltic pump rod are driven to rotate by the first bevel gear, so that the peristaltic pump rod rotates inside the peristaltic pump housing to squeeze the infusion tube, so that the liquid in the infusion tube enters the mixing chamber through the flow meter, and the flow meter measures the amount of the liquid for the first time;

[0027] Step 3: When the liquid enters the mixing chamber, the electronic weighing device will weigh the liquid inside the mixing chamber, and at the same time, the scale mark in the scale will be driven by the floating block to move up and down through the sliding column to complete the second measurement;

[0030] When the mixing chamber is discharging pressure, the exhaust hole will transmit the pressure, causing the sliding shell to rise under the air pressure discharged by the exhaust hole, thereby discharging the pressure inside the mixing chamber.

[0031] Compared with the prior art, the present invention has the following beneficial effects: the driving motor drives the mixing mechanism and the infusion mechanism to operate, so that when the driving motor drives the mixing mechanism to operate, the infusion mechanism can be driven to operate at the same time, so that the infusion mechanism records the transmission amount of each raw material, and then the water level reached by all the raw materials is recorded through the scale, so that when the vitamin injection is proportioned, the amount of the raw materials can be monitored through the infusion mechanism and the scale;
