[0030] A liquid medicine diverter and a liquid medicine buffer tank thereof, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes a diverter shell 10, a collar 12 is fixedly connected to the inner side of the top of the diverter shell 10, a fixing plate 11 is fixedly connected to the top surface of the diverter shell 10, and the fixing plate 11 is located between the diverter shell 10 and the collar 12; a flow-aiding structure, the flow-aiding structure is fixedly arranged inside the diverter shell 10, the flow-aiding structure includes a diverter tube 14, a diverter ball 15 and a flow-aiding ball 17, the diverter ball 15 is fixedly arranged in the diverter shell 10, the flow-aiding ball 17 is fixedly arranged above the diverter ball 15, and the diverter tube 14 is fixedly arranged on the outside of the diverter shell 10; a local control structure, the local control structure is rotatably arranged on the outside of the diverter shell 10, the local control structure includes a stop valve 18, a telescopic rod 19, a gear 20 and a gear ring 21, the telescopic rod 19 is fixedly arranged on the top of the stop valve 18, the stop valve 18 is threadedly arranged at one end of the diverter tube 14, the gear 20 is fixedly arranged on the top surface of the telescopic rod 19, and the gear ring 21 is rotatably arranged on the outer curved surface of the diverter shell 10.

[0031] The working principle is as follows: by setting a local control structure, rotating the gear ring 21, and utilizing the gear ring 21 to mesh and transmit six gears 20, six stop valves 18 can stop or release flow at the same time; by lifting the gear 20, the telescopic rod 19 can be extended and retracted; when the gear 20 is higher than the position of the gear ring 21, the stop valve 18 connected to the gear 20 is away from the synchronous control of the gear ring 21; at this time, the stop valve 18 can realize autonomous control of stopping flow or releasing flow, so that the device can control a certain stop valve 18 to close the corresponding shunt tube 14 to stop flow according to the needs of liquid medicine packaging, thereby achieving the effect of local shunt, and further improving the applicability of the device; by setting a flow-aiding structure, the sphere of the flow-aiding ball 17 is utilized to perform arc-shaped flow-aiding on the liquid medicine, and at the same time, the shunt ball 15 is provided with six shunt directions, which can meet the needs of different directions and different shunt work, thereby speeding up the work efficiency to a certain extent and improving the practicality of the device.

[0032] like Figure 2 As shown, the fixing plate 11 is provided with four circular holes at positions away from the four corners, and bolts 13 are clamped in the circular holes. The fixing plate 11 is fixed to the bottom surface of the buffer tank body by the bolts 13; Figure 1 and Figure 3As shown, the flow-dividing shell 10 is composed of a torus and a hemispherical cylinder. The flow-dividing ball 15 is a sphere, which is fixedly connected in the hemispherical cylinder. A spherical groove is provided on the top of the flow-dividing ball 15, and a flow-aiding ball 17 is fixedly connected in the spherical groove. Figure 1 and Figure 3 As shown, six diverter grooves 16 are evenly provided on the top curved surface of the diverter ball 15 , and six through holes are evenly provided in the annular cylinder of the diverter housing 10 , which are communicated with the diverter grooves 16 .

[0033] The working principle is as follows. Before use, the fixing plate 11 is pressed against the bottom surface of the buffer tank body, and the bolts 13 are used to fix the entire device to the buffer tank body. Then the medicine in the buffer tank body flows down to the diversion shell 10, passes through the surface of the flow-aiding ball 17 and flows through the diversion groove 16. Part of the medicine passes through the surface of the diversion ball 15 and flows through the diversion groove 16, and then converges in the diversion pipe 14 to achieve diversion. Here, the junction between the diversion ball 15 and the diversion groove 16 is set as an arc surface. The arc surface and the hemispherical structure are more convenient for the flow of liquid. At the same time, the spherical surface makes the flow direction of the medicine a spherical direction. In the whole process, the medicine flows on the surface of the diversion ball 15 and converges in the diversion shell 10, and the medicine can reach the diversion groove 16 through the arc surface, and then be diverted through the diversion pipe 14.

[0034] like Figure 1 , Figure 2 and Figure 4 As shown, one end of the shunt pipe 14 is fixedly connected to the outer curved surface of the shunt housing 10, six shunt pipes 14 are provided, the shunt pipes 14 are arranged opposite to the through hole, the other end of the shunt pipe 14 is provided with a thread, the stop valve 18 is a T-shaped structure, both ends of the stop valve 18 are provided with threaded holes, and the shunt pipe 14 is threadedly connected with the threaded hole of the stop valve 18; Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a slip ring 23 is fixedly connected to the inner side of the gear ring 21, an annular column is fixedly connected to the top surface of the gear ring 21, a handle 22 is fixedly connected to the top surface of the annular column, the gear ring 21 and the handle 22 are rotatably connected to the outer wall of the flow splitting housing 10 through the same annular column, the handle 22 is located directly below the fixed plate 11, and a ring groove 24 is opened on the outer side of the flow splitting housing 10, the ring groove 24 is located between the fixed plate 11 and the flow splitting pipe 14, and the slip ring 23 rotates and slides in the ring groove 24; Figure 4 As shown, the top of the stop valve 18 is fixedly connected to the bottom wall of the telescopic rod 19, the top surface of the telescopic rod 19 is fixedly connected to the bottom surface of the gear 20, and the gear 20 drives and meshes with the gear ring 21.

[0035] The specific implementation is as follows. First, the stop valve 18 used in the device is composed of a T-shaped cylinder, an internal resistance block and a handle threaded rod. The handle threaded rod is rotatably arranged in the T-shaped cylinder, and the handle threaded rod is threadedly connected to the internal resistance block. Here, the interior of the T-shaped cylinder is a T-shaped through cavity, and the internal resistance block is located in the middle of the T-shaped through cavity. When in use, the rotation of the handle threaded rod will drive the internal resistance block to move up and down in the T-shaped through cavity. When moving up, the stop valve 18 is in an open state, and when moving down, the stop valve 18 is in a closed state. Before use, first rotate the handle 22 to control the gear ring 21 to engage with the six gears 20 at the same time. The gear 20 drives the rotation of the handle threaded rod. The handle threaded rod prompts the internal resistance block to move down to block the T-shaped through cavity in the T-shaped cylinder, thereby closing the six stop valves 18 at the same time. At this time, the bolt 13 is used to connect the entire device to the buffer tank The main body is fixed, and then the medicine liquid in the buffer tank body flows down to the diversion shell 10, passes through the surface of the flow-aiding ball 17 to reach the top surface of the diversion ball 15, flows through the diversion groove 16, and then converges in the diversion shell 10. At this time, the stop valve 18 is opened as needed. Here, if all of them need to be opened, the handle 22 is turned in the opposite direction, and the toothed ring 21 engages with the six gears 20 in the opposite direction to achieve the simultaneous opening of the six stop valves 18. If one or more of the six stop valves 18 need to be opened, the gear 20 above the threaded rod of the handle of the remaining stop valves 18 that do not need to be opened is pulled up to extend the telescopic rod 19 and move the gear 20 away from the toothed ring 21. Then the handle 22 is turned in the opposite direction to achieve the simultaneous opening of the local stop valves 18. At this time, the medicine liquid flows through the diversion pipes 14 corresponding to these stop valves 18 to achieve diversion.
