[0025] The following is combined with Figure 1-Figure 6 This embodiment is described in further detail.

[0026] Combined with Figure 1-Figure 3In this embodiment, a liquid dispensing tank with a stirring function includes a tank body 100, a stirring chamber with an upper opening is provided in the tank body 100, a cover plate 110 is provided at the opening position of the stirring chamber, a drug inlet 112 is provided on the cover plate 110, and the drug inlet 112 is used to add drug powder into the stirring chamber, a water inlet pipe 120 is provided on the outer wall of the tank body 100, and the water inlet pipe 120 is used to input water into the stirring chamber, and a stirring component is provided on the cover plate 110, and the stirring component is used to In order to stir the liquid medicine, a water storage ring 130 is provided on the lower side surface of the cover plate 110 along its circumference, and a water inlet pipe 122 extending out of the tank body 100 is provided on the outer wall of the water storage ring 130. The water inlet pipe 122 is connected to the water inlet pipe 120 through a delivery pipe 121. A plurality of water spray pipes 131 are evenly arranged on the lower end surface of the water storage ring 130 along its circumference. The water spray pipes 131 are used to spray the water in the water storage ring 130 onto the side wall of the stirring chamber located above the water inlet pipe 120.

[0027] In actual use of this embodiment, the drug inlet 112 includes a hole provided on the cover plate 110 and a drug inlet pipe provided in the hole. The lower end of the drug inlet pipe is extended into the stirring chamber. The lower end of the drug inlet pipe is flush with the lower end of the water spray pipe 131. The drug powder is added into the stirring chamber through the drug inlet pipe. Some of the drug powder adheres to the side wall of the stirring chamber below the water spray pipe 131.

[0028] The water inlet pipe 120 is arranged on the outer wall of the tank body 100 below the water spray pipe 131, so that there is a certain height difference between the two, that is, the medicine powder added to the stirring chamber will partially adhere to the side wall of the stirring chamber between the height difference. The water inlet pipe 120 is used to pump the water used for preparing the medicine liquid into the stirring chamber, so that both the medicine powder and water can be added to the stirring chamber. At this time, the medicine powder and water in the stirring chamber can be stirred and mixed by starting the stirring component to obtain the desired medicine liquid;

[0029] In this embodiment, by setting the water inlet pipe 120, the delivery pipe 121, and the water inlet pipe 122, in actual use, a one-way valve is set on the water inlet pipe 120 between the delivery pipe 121 and the outer wall of the tank body 100. When the water inlet pipe 120 pumps water into the stirring chamber, the one-way valve on the water inlet pipe 120 is opened to allow water to be pumped into the stirring chamber through the water inlet pipe 120. When the one-way valve is closed, the water in the water inlet pipe 120 is pumped into the water inlet pipe 122 through the delivery pipe 121. The water in the water storage ring 130 can be sprayed out through the water spray pipe 131 to spray the powder adhered to the inner wall of the stirring chamber, so that the powder adhered to the inner wall of the stirring chamber can be sprayed into the liquid medicine to be stirred and dissolved; compared with the existing method, by spraying water onto the inner wall of the stirring chamber, the powder adhered to the inner wall of the stirring chamber can be sprayed into the liquid medicine to prevent the powder from adhering to the inner wall of the stirring chamber, resulting in a decrease in the concentration of the liquid medicine prepared by the liquid preparation tank;
