[0036] The partition plate 17 is arranged in two, and the communication hole 21 is arranged on the side of the partition plate 17 away from the layering pipe 13, the middle cavity 19 is communicated with the lower cavity 18 and the upper cavity 20 through the communication hole 21, and the main through pipe 22 and the exhaust pipe 23 are connected to the dosing pipe.

[0037] The mixing box 1 is divided into the lower cavity 18, the middle cavity 19 and the upper cavity 20 through the partition plate 17, the medicaments can be mixed in three parts, the mixing path is prolonged, the mixing uniformity is improved, the finally mixed medicaments can enter into the dosing pipe through the main through pipe 22, the exhaust pipe 23 is closed during mixing to avoid the liquid loss, and the medicaments remaining in the lower cavity 18 are discharged through the exhaust pipe 23 when the dosing is about to end.

[0038] The flow resistance plate 25 is vertically arranged in the lower cavity 18 and the upper cavity 20, and is located between the inlet of the layering pipe 13 and the communication hole 21, and the flow resistance plate 25 is controlled through the straight rail 24 connected to the partition plate 17.

[0039] The flow resistance plate 25 is arranged in the lower cavity 18 and the upper cavity 20, and the medicaments entering into the flow resistance plate 25 can enter into the middle cavity 19.

[0040] The bottom of the flow resistance plate 25 is provided with the hard sealing strip 26, the top of the flow resistance plate 25 is provided with the soft sealing pad 27, the turbulence type structure comprises the through slot arranged on the flow resistance plate 25, and the turbulence piece 28 is arranged in the through slot.

[0041] In fact, the upper part of the baffle 25 is provided with a certain gap from the top of the mixing box 1 or the top of the partition, so that the baffle 25 is lifted under the control of the linear track 24. In addition, the gap in the upper part of the baffle 25 is sealed by a soft sealing gasket 27, the thickness and shape of which can be selected according to actual needs, and it is also a soft deformable structure, for example Figure 9 As shown in FIG. 8, the soft sealing gasket 27 can be L-shaped after extrusion deformation, which also has a sealing effect and ensures that the baffle 25 is not blocked by a soft structure.

[0042] The baffle 25 is provided with a turbulence passing structure. Under normal circumstances, the baffle 25 is controlled at the bottom by the linear track 24, and the upper and lower sides of the baffle 25 are sealed by the hard sealing strip 26 and the soft sealing gasket 27. The medicament can only pass through the position of the turbulence sheet 28, which rotates under the action of the water flow to increase the homogenization effect of the multiple medicaments.

Only the medicaments that enter the middle cavity 19 after passing through the baffle 25 can ensure that the medicaments have been mixed and uniform, and the flow rate is limited by the layered pipe 13 and the baffle 25, so that the medicaments are overflowed into the middle cavity 19.

[0046] The medicaments entering into the middle layer cavity 19 from the lower layer cavity 18 and the upper layer cavity 20 have been subjected to a primary mixing process, and the flow rate is limited by the limiting layered pipe 13 and the blocking plate 25, so that the medicaments are poured into the middle layer cavity 19, and the flow rate in the layered pipe 13 connected to the middle layer cavity 19 is the slowest, and the medicaments in the lower layer cavity 18, the middle layer cavity 19 and the upper layer cavity 20 can be converged at the position of the drainage plate 29 to perform a final mixing and homogenization process through the guidance of the drainage plate 29.
