Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Existing mixing devices for atomized drug production have poor mixing efficiency and are inconvenient to disassemble and clean. To solve this technical problem, this embodiment discloses the following technical content.

[0029] Please see Figures 1-5 A mixing device for producing atomized medicine liquid includes a mixing tank 1, an observation window 2, a tank cover 3, a feed hopper 4, a motor 5, a toothed disc 6, a toothed ring 7, a connecting pipe 8, a first stirring pipe 9, a second stirring pipe 10, a third stirring pipe 11, a nozzle 12, a first conveying pipe 13, a second conveying pipe 15, a filter screen 16, a third conveying pipe 17, a discharge pipe 18, a control valve 19, and a controller 20.

[0030] An observation window 2 is installed at the front end of the mixing tank 1, through which the mixing of the atomized medicine solution can be observed;

[0031] The top of the mixing tank 1 is fixed with a tank cover 3 by screws, and the top of the tank cover 3 is fixed with a feed hopper 4. The feed hopper 4 conveys the material into the mixing tank 1. The mixing tank 1 is equipped with a stirring assembly, which stirs the material.

[0032] like Figure 2 and Figure 4 As shown, the stirring assembly includes a motor 5, a toothed disc 6, a toothed ring 7, a connecting pipe 8, a first stirring pipe 9, a second stirring pipe 10, a third stirring pipe 11, and a nozzle 12. The motor 5 is fixed on the upper surface of the can lid 3. The toothed disc 6 is fixed at the output end of the motor 5. The toothed ring 7 is meshed with the right end of the toothed disc 6. The connecting pipe 8 is fixed inside the toothed ring 7. The first stirring pipe 9 is fixed at the bottom end of the connecting pipe 8. The second stirring pipe 10 is fixed at the bottom end of the first stirring pipe 9 by screws. The third stirring pipe 11 is installed at the outer end of the second stirring pipe 10. The nozzles 12 are fixed at equal intervals at the outer end of the third stirring pipe 11. The third stirring pipe 11 is installed on both the left and right sides of the second stirring pipe 10. The nozzles 12 on the third stirring pipe 11 on the left and right sides of the second stirring pipe 10 are arranged one above the other. The first stirring pipe 9 passes through the middle of the top of the can lid 3.

[0033] When the medicine solution is stirred and mixed, the motor 5 is started by the controller 20. The motor 5 drives the toothed disc 6 to rotate, and the toothed ring 7 that meshes with the toothed disc 6 rotates, thereby rotating the connecting pipe 8, the first stirring pipe 9, the second stirring pipe 10, the third stirring pipe 11 and the nozzle 12. The material is stirred by the rotation of the first stirring pipe 9, the second stirring pipe 10 and the third stirring pipe 11.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, a circulation conveying assembly is provided on the left side of the mixing tank 1. The circulation conveying assembly includes a first conveying pipe 13, a material pump 14, a second conveying pipe 15, a filter screen 16, and a third conveying pipe 17.

The first conveying pipe 13 is fixed to the tank cover 3 by a rod.

[0035] When mixing materials, the materials circulate inside the mixing tank 1 through the circulating conveying component. Under the action of the material pump 14, the materials pass through the filter screen 16 and flow to the second conveying pipe 15, and then flow from the third conveying pipe 17 to the first conveying pipe 13. Then, they are conveyed to the connecting pipe 8, the first stirring pipe 9, the second stirring pipe 10 and the third stirring pipe 11. The materials flow out from the nozzles 12. Since the nozzles 12 are set up one above the other and are evenly spaced inside the mixing tank 1, the sprayed materials are evenly sprayed into the materials, improving the mixing effect. The liquid medicine sprayed from the nozzles 12 impacts the liquid medicine inside the mixing tank 1, causing the liquid medicine to tumble.

[0036] A controller 20 is fixedly installed on the right side of the mixing tank 1, which controls the motor 5, the material pump 14 and the control valve 19.

[0037] A discharge pipe 18 is fixed at the bottom of the mixing tank 1, and a control valve 19 is installed on the discharge pipe 18. When discharge is required, the control valve 19 is opened and the material flows out from the discharge pipe 18.

[0038] When cleaning is required, remove the screws connecting the mixing tank 1 and the tank cover 3, then remove the screws on the first conveying pipe 13 and the third conveying pipe 17, then lift the tank cover 3, remove the tank cover 3 and the stirring assembly, disassemble the screws connecting the first stirring pipe 9 and the second stirring pipe 10, and clean each part of the stirring assembly separately.

[0039] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.
