[0043] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for the convenience of description, only the parts related to the utility model are shown in the accompanying drawings.

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0045] Please refer to Figure 1-2 , an embodiment of the utility model provides a rapid dispensing pump, comprising:

[0046] The top of the housing component 1 is connected to a feed hopper 11 at one end, and the bottom of the other end is connected to a liquid outlet pipe 12. Both sides of the feed hopper 11 near the bottom are symmetrically connected to first reflux stirring pipes 31.

[0047] The water inlet assembly 2 includes a water inlet pipe 21 and an inlet diffuser 22. The water outlet end of the water inlet pipe 21 extends into the bottom of the feed hopper 11 and is connected to a Laval tube. The inlet diffuser 22 is arranged in the housing assembly 1 and communicates with the bottom end of the feed hopper 11.

[0048] The reflux pipeline 3 is respectively connected with the housing assembly 1 and the first reflux stirring pipe 31;

[0049] The stirring component 4 is arranged in the housing component 1, and the gap between the stirring component 4 and the inner cavity of the housing component 1 forms a Tesla valve structure;

[0050] The driving assembly 5 is transmission-connected with the stirring assembly 4 and is used for driving the stirring assembly 4 to rotate.

[0051] In this embodiment, the required medicine is placed in the feed hopper 11 and mixed with the liquid medicine in the return line 3 to form a premixed powder water. Water is injected into the water inlet pipe 21, and the premixed powder water is flushed into the inlet diffuser 22 through the Laval tube at the lower end. The inlet diffuser 22 is connected to the inlet of the premixing chamber 131 for the liquid medicine flowing in the lower part of the hopper 11 to form a Venturi tube structure. The pressure at the outlet end of the inlet diffuser 22 is lower than the pressure at the inlet end, so that the premixed powder water is sucked into the premixing chamber 131 of the liquid shell. The suction impeller 42 in the chamber 131 and the boost chamber 132 sucks the premixed powder water into the boost chamber 132 and stirs it into liquid medicine. Then the liquid medicine enters the stirring chamber for full stirring. The stirred liquid medicine enters the liquid outlet shell 15. The liquid medicine first enters the collecting chamber 151 of the liquid outlet shell. The collecting chamber 151 is connected to the reflux pipeline 3 below. Part of the liquid medicine is refluxed through the reflux pipeline 3. When the liquid in the collecting chamber 151 is full, it flows into the temporary storage chamber 152. The liquid medicine flows out of the rapid dispensing pump through the liquid outlet pipe 12.

[0052] The gap between the stirring blade 43 of the rapid dispensing pump of the present application and the inner cavity of the shell component 1 forms a three-dimensional Tesla valve structure, which slows down the speed of the medicine liquid flowing into the next stage through the physical structure, so that the medicine liquid is fully stirred, and the problem of easy deposition of the medicine liquid is solved; the Laval tube structure and the Venturi tube structure allow the premixed medicine powder water to quickly enter the rapid dispensing pump, thereby improving the working efficiency; the suction impeller 42 sucks the premixed medicine liquid from the premixing chamber 131 into the boosting chamber 132, ensuring that the pressure of the premixing chamber 131 is lower than the atmospheric pressure, preventing the medicine liquid from overflowing the shell component 1; the stirring blade 43 and the stirring chamber form a three-dimensional Tesla valve structure, which slows down the speed of the medicine liquid flowing into the next stage through the physical structure, so that the medicine liquid is fully stirred, and the problem of easy deposition of the medicine liquid is solved.

[0056] A collecting chamber 151 and a temporary storage chamber 152 are sequentially arranged in the liquid outlet shell 15 from one end to the other end. The tops of the collecting chamber 151 and the temporary storage chamber 152 are connected; the collecting chamber 151 is connected to the stirring chamber adjacent thereto; and the liquid outlet pipe 12 is connected to the bottom of the temporary storage chamber 152.

[0057] In this embodiment, the liquid inlet housing 13, the stirring housing 14 and the liquid outlet housing 15 are installed compactly at each level, thereby reducing the volume of the rapid dispensing pump.

[0058] In a preferred embodiment, if Figure 1 As shown, one side of the top of the premixing chamber 131 is connected to the reflux pipeline 3 through the second reflux stirring tube 32, so that the liquid medicine refluxes into the premixing chamber 131 to increase the volume of the premixed powder water.

[0063] In this embodiment, the stirring blade 43 is designed as a straight blade or a curved blade or a solid cone structure such as Figure 3 As shown, the structure with grooves on the surface or holes inside forms a Tesla valve structure with the gap between the stirring shell, which has a simple structural design and low cost.

Mechanical or electronic interlocking mechanisms simplify the operating steps and make control more convenient.
