When the infusion pump overflows, the overflowing liquid medicine can enter thewater inlet 3 and be ejected from thewater outlet 4 so as to push the water flow in the liquid medicine box to flow and promote the liquid medicine with different concentrations in the liquid medicine box to be mixed, so that the liquid medicine in the liquid medicine box reaches a state with more uniform concentration. Meanwhile, aspray head 5 is arranged on thewater outlet 4, and thespray head 5 is in threaded connection with thewater outlet 4. The flow direction of the liquid medicine sprayed out of thespray head 5 is parallel to the tangential direction of theshell 1 at the position opposite to thespray head 5. And simultaneously, all the liquid sprayed by thespray head 5 is sprayed in the clockwise direction. Therefore, when the infusion pump works, the liquid medicine in the liquid medicine box can flow clockwise and form a vortex relatively quickly, so that the liquid in the liquid medicine box flows, and the effect of mixing different concentrations is achieved.

Meanwhile, the top of theshell 1 is provided with awater supply port 2, thewater supply port 2 is positioned between triangles enclosed by a circular pipeline, thewater supply port 2 is communicated with an opening at the lower part of theshell 1, when in use, thewater supply port 2 is connected with a liquid suction port of the liquid conveying pump, and liquid medicine enters theshell 1 from the opening at the lower part of theshell 1 and enters the liquid conveying pump through thewater supply port 2. The reason why thewater supply port 2 is arranged at the position is that the water flow at the position is stable, and the energy consumption of the liquid suction pump on the liquid suction port is low when the liquid medicine is sucked, so that the energy is saved. Meanwhile, a first filter screen and a second filter screen are respectively arranged on thewater supply port 2 and the opening at the lower part of theshell 1. The first filter screen and the second filter screen are pressed on theshell 1 in a hot pressing mode. The first filter screen sets up at the 2 lower extremes of feed water inlet, and the second filter screen setting is greater than the second filter screen at 1 lower extreme opening part of casing, the filter fineness of first filter screen. When the liquid medicine enters the infusion pump, the liquid medicine needs to be filtered by the first filter screen and the second filter screen, so that the cleanliness of the liquid medicine entering the infusion pump can be better improved, and the infusion pump is prevented from being damaged due to entering impurities.

In addition, as shown in fig. 1, 2 and 3, in order to avoid negative pressure generated in thecasing 1 when the infusion pump works due to the fact that water in thecasing 1 flows to the infusion pump, the opening at the lower end of thecasing 1 is attached to the bottom of the liquid medicine tank, so that liquid medicine normally enters thecasing 1,support legs 6 are integrally arranged at the lower portion of thecasing 1, the distance between the lower end of thecasing 1 and the bottom of the liquid medicine tank is increased, and the liquid medicine conveniently enters thecasing 1. Thefeet 6 are evenly distributed on the circumference of the lower part of theshell 1 to obtain better supporting effect and better flow capacity.

During operation, liquid medicine enters the inner wall of theshell 1 from the channel between thesupport legs 6, and simultaneously the liquid medicine is filtered by the first filter screen and the second filter screen and then enters the infusion pump through thewater supply port 2. After the liquid medicine is pressurized by the infusion pump, one part of the liquid medicine is sprayed out of the spray rod, the other part of the liquid medicine overflows from the overflow port and enters thewater inlet 3 on the liquid medicine stirrer through the pipeline to be sprayed out of thewater outlet 4 finally, the liquid medicine in the liquid medicine box is driven to flow, so that the liquid medicine in the liquid medicine box is better mixed, and the concentration of the liquid medicine box reaches a more uniform state.
