Through the above settings, the linear motor is started, and the linear slider moves linearly along the axial direction of the output shaft of the linear motor. When it moves upward, it will drive the pressing plate to move upward to pull out the rubber plug from the lower opening of the liquid storage tube. During the movement, the rubber plug recovers to be tightly engaged with the lower opening of the liquid storage tube under the action of the spring, that is, the linear motor and spring are used to control the opening and closing of the lower opening of the liquid storage tube, which further reduces the labor intensity of medical staff .

Preferably, the liquid storage tank is also connected with a metering connecting rod, the metering connecting rod is engraved with a scale mark, the metering connecting rod is connected with two limit sliders through bolts, and the pressing plate is connected with a metering slider The metering slide bar is also slidingly connected with the metering connecting rod, and the metering slide bar is arranged between two limit sliders.

Through the above settings, the limit sliders on the upper and lower sides are precisely fixed and positioned in advance with the help of the scale mark on the metering connecting rod, so as to realize the precise control of the time when the rubber plug is pulled up, that is, by controlling the sliding distance of the metering slider , so as to control the liquid discharge time in the liquid storage tube, and finally realize the control of the liquid discharge volume. The control of the liquid discharge volume of the liquid storage tube installed inside the liquid storage tank is intuitive, ensuring the correct mixing ratio of the liquid medicine, and easy operate.

Preferably, the diameter of the lower opening of the liquid storage tube is smaller than the diameter of the upper opening of the rotating tube.

Through the above arrangement, the liquid medicine in the liquid storage tube flows into the upper opening of the rotating tube from the lower opening, reducing the spilling of the liquid medicine in the process.

Preferably, there are six liquid storage components, and the six liquid storage components are evenly distributed on the outside of the driving gear.

Through the above setting, the mixing of up to six kinds of medicinal liquids can be realized, and the uniform arrangement of the six pieces makes the whole device more stable, which is beneficial to prolonging the service life of the device.
