[0050] The control switch 5 is used to switch the blocking and opening states of the purge air duct structure.

[0051] The medicine bottle dispensing structure of the present invention can realize the compartment storage of liquid and powdered medicines. When in use, by pressing the adjusting cover, different medicines are discharged from the first row of ports, the second row of ports and the third row of ports that are connected. After the first adjusting cover is elastically reset, the connecting thin tubes at both ends of the second row of ports are pulled outward, and its inner cavity is tightened and a relatively high pressure is formed in the second row of ports to prevent liquid medicines from seeping out from the relatively low-pressure storage compartment; before the second adjusting cover is released, the control switch can be operated so that the relatively high-pressure variable pressure chamber caused by the synchronous activity of the piston plate when the second adjusting cover is pressed is connected to the purge air duct structure, so that the gas therein is blown out, and the medicines in the first row of ports and the third row of ports corresponding to the powdered medicines are purged so that they are blown back into the storage compartment, thereby realizing the medicine dispensing and taking out without leakage. The multi-layer design of the medicine dispensing cover and the adjusting cover can ensure the stability of the lateral sliding structure without vertical displacement, ensure the sealed docking between the two medicine outlets, and prevent the medicines from leaking into the pressing cavity.

[0052] A central column 11 is provided in the middle of the medicine bottle body 1, and the central column 11 is connected to the outer partition 12, and the central column 11 is inserted into the slot 21 in the center of the medicine dispensing cover 2, and the fan-shaped block 22 is embedded and assembled in the storage compartment, and the card groove 13 on the outer wall of the bottle mouth of the medicine bottle body 1 is engaged and positioned with the card block 23 in the bottom inner cavity of the medicine dispensing cover 2. The above-mentioned chimeric splicing design can ensure the close docking of the medicine bottle body 1 and the medicine dispensing cover 2, and avoid cross contamination of different drugs in each storage compartment or leakage to the outside of the drugs.

[0053] The mouth of the medicine bottle body 1 is sleeved with a sealing kit that is tightly assembled with the bottom cavity of the medicine dispensing cover 2 and the fan-shaped block 22. The outer side of the mouth of the medicine bottle body 1 is provided with a first sealing gasket 14 that is sealably assembled with the bottom edge of the medicine dispensing cover 2. The outer side of the end of the third row of ports 41 is sealed and connected to the pressing cavity 25 through the first sealing gasket 14, thereby further improving the independence of the storage of multiple types of medicine compartments.

[0054] The top of the middle column 11 is provided with a first pressurized cavity 15 docking with the slot 21, and the bottom side of the first pressurized cavity 15 extends with a second pressurized cavity 16 docking with the sealing kit. This design mainly realizes the drug leakage prevention of the gap between the sealing kit and the storage compartment and the bottom cavity of the medicine dispensing cover 2 through the pressure difference between the pressurized cavity and the storage compartment, thereby avoiding drug cross contamination.

[0055] The first adjustment cover 3, the second adjustment cover 4 and the pressing cavity 25 are elastically connected by the first elastic pressing block 33 and the second elastic pressing block 42 respectively. A flip cover can also be provided at the first row of openings 24 at the bottom corresponding to the second adjustment cover 4, so that when the second adjustment cover 4 is not pressed and the third row of openings 41 are not connected to the first row of openings 24, the second adjustment cover 4 can block the flip cover to prevent it from opening and causing the medicine to be spilled into the pressing cavity 25, and only when the third row of openings 41 is connected to the first row of openings 24, the flip cover can be opened to pour out the medicine.

[0056] The branch extending from the side of the normal pressure chamber is connected to the re-pressure hole 26 , and the variable pressure chamber is connected to the re-pressure hole 26 through the pressing chamber 25 .

[0057] The purge air duct structure includes an L-shaped air duct 27 connected to the transformer chamber and an annular air duct 28 connected to the end of the L-shaped air duct 27 . An inner air duct connected to the first outlet 24 corresponding to the second regulating cover 4 is radially extended from the inner side of the annular air duct 28 .

[0058] The pressing block 51 of the control switch 5 is press-type elastically docked with the pressing groove 29 on the surface of the medicine dispensing cover 2 through the reset elastic member 52, the reset elastic member 52 is sealed at the top of the pressing groove 29, the bottom of the pressing groove 29 passes through the L-shaped air duct 27, the blocking member 53 at the bottom of the pressing block 51 is inserted into the L-shaped air duct 27, and the blocking member 53 is provided with a through hole 54 corresponding to the L-shaped air duct 27.

[0059] The working principle of the multi-layer compartment medicine bottle dispensing structure of this embodiment includes: when in use, the first pressurized chamber 15 is closed with the slot 21 and forms a relatively high pressure due to the plug-in sealing assembly of the medicine dispensing cover 2 and the medicine bottle body 1. Through the pressure difference between it and the storage compartment, the medicine therein is prevented from leaking out of the gap and cross-contamination with other medicines. When the liquid medicine is discharged for use, such as Figure 6 , 7, press the first adjustment cover 3 inwards, so that the corresponding first row of ports 24, second row of ports 31, and connecting thin tubes 32 are connected, and the medicine can be poured out. When the first adjustment cover 3 is released, it is reset and the connecting thin tube 32 is pulled outwards, so that the inner cavity of the connecting thin tube 32 is closed, and a relatively high pressure is formed in the second row of ports 31 to prevent the liquid medicine from seeping upwards from the first row of ports 24 and connecting thin tubes 32 when it is idle. When the powdered medicine is discharged for use, Figure 8-10 , press the second regulating cover 4 inwardly, so that the third row of ports 41 connect with the first row of ports 24 on the upper and lower sides, and isolate it from the pressing chamber 25 through the first sealing gasket 14. At this time, the second sealing gasket 43 is blocked at the bottom of the piston chamber 20 to achieve airtightness, and the piston plate 44 moves synchronously to pressurize one side of the pressure-changing chamber, and then the medicine can be poured out; after the medicine is taken out, press the control switch 5 to move the blocking member 53 downward, and the through hole 54 connects with the L-shaped air duct 27, so that the relatively high-pressure gas in the pressure-changing chamber can be discharged from the L-shaped air duct 27 and the annular air duct 28, and the residual powder in the third row of ports 41 and the first row of ports 24 is purged to blow it back into the storage compartment at the bottom, and then the second regulating cover 4 can be loosened to reset it, the row of ports is closed, and the piston chamber 20 is connected to the pressing chamber 25 and the re-pressure hole 26 to re-pressurize the pressure-changing chamber and replenish gas.

[0060] In summary, due to the adoption of the above technical solution, the multi-layer compartment medicine bottle medicine dispensing structure of this embodiment has the following beneficial effects compared with the prior art:

[0061] The medicine bottle dispensing structure of the present invention can realize the compartment storage of liquid and powdered medicines. When in use, by pressing the adjusting cover, different medicines are discharged from the first row of ports, the second row of ports and the third row of ports that are connected. After the first adjusting cover is elastically reset, the connecting thin tubes at both ends of the second row of ports are pulled outward, and its inner cavity is tightened and a relatively high pressure is formed in the second row of ports to prevent liquid medicines from seeping out from the relatively low-pressure storage compartment; before the second adjusting cover is released, the control switch can be operated so that the relatively high-pressure variable pressure chamber caused by the synchronous activity of the piston plate when the second adjusting cover is pressed is connected to the purge air duct structure, so that the gas therein is blown out, and the medicines in the first row of ports and the third row of ports corresponding to the powdered medicines are purged so that they are blown back into the storage compartment, thereby realizing the medicine dispensing and taking out without leakage. The multi-layer design of the medicine dispensing cover and the adjusting cover can ensure the stability of the lateral sliding structure without vertical displacement, ensure the sealed docking between the two medicine outlets, and prevent the medicines from leaking into the pressing cavity.
