[0022] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.
[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0024] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A liquid preparation preparation tank according to this specific embodiment includes a tank body 1. The top of the tank body 1 is fixedly connected to an inlet pipe 9. The top of the inlet pipe 9 is fixedly connected to a storage box 8. The top of the storage box 8 is fixedly connected to a pressure tank 3. A connecting pipe 11 is fixedly connected to one side of the storage box 8. A metering mechanism 2 is provided at one end of the connecting pipe 11.
[0025] The metering mechanism 2 includes an electric telescopic rod 201. A mounting plate 5 is fixedly connected to the bottom of the electric telescopic rod 201. One side of the mounting plate 5 is fixedly connected to the surface of the tank body 1. A push-pull rod 6 is fixedly connected to the telescopic end of the electric telescopic rod 201. A push rod 204 is fixedly connected to one end of the push rod 6, and a tube 202 is movably connected to its surface. One end of the tube 202 is fixedly connected to one end of the connecting pipe 11. A circular plate 205 is fixedly connected to one side of the push rod 204. A rubber block 206 is fixedly connected to the surface of the circular plate 205, and the surface of the rubber block 206 is in close contact with the inner wall of the tube 202. One-way valves are fixedly connected to both sides of the tube 202. 203, A limiting ring 207 is fixedly connected to the inner wall of the tube 202; By setting a metering mechanism 2, the dosage of medicine added into the tank 1 can be controlled under the action of the metering mechanism 2. At the same time, when adding medicine, the medicine remaining on the inner wall can be fully added, avoiding the medicine remaining on the inner wall from affecting the next use. This avoids the residual liquid preparation entering different liquid preparations, causing the later liquid preparation to contain the components of the first liquid preparation. This achieves the purpose of making it convenient for users to control the amount of medicine when adding medicine, and at the same time, ensuring that the medicine fully enters the tank 1.
[0026] Reference Figure 3 The bottom of the tube body 202 is fixedly connected with three fixing rings 4. The bottom of the fixing rings 4 is fixedly connected with two support blocks 12. The bottom of the support blocks 12 is fixedly connected with a connecting frame 13. The bottom of the connecting frame 13 is fixedly connected to the top of the mounting plate 5. By setting the fixing rings 4, support blocks 12 and connecting frames 13 together, the stability and firmness of the tube body 202 during use can be increased, and the tube body 202 can be prevented from shifting and shaking during use, thus achieving the purpose of increasing the stability and firmness of the tube body 202 during use.
[0027] Reference Figure 2 The inner wall of the mounting plate 5 is provided with a mounting groove 10. The inner wall of the mounting groove 10 is fixedly connected to the bottom of the electric telescopic rod 201. By setting the mounting groove 10, the user can easily fix the electric telescopic rod 201 to the mounting plate 5 under the action of the mounting groove 10, thereby increasing the stability and firmness between the electric telescopic rod 201 and the mounting plate 5.
[0028] Reference Figure 1 and Figure 2 The bottom of the mounting plate 5 is fixedly connected with two support legs 7. The support legs 7 are fixedly connected to the tank 1 on the side closest to the tank 1. By setting the support legs 7, the stability of the mounting plate 5 during use can be increased under the action of the support legs 7, thereby achieving the purpose of further increasing the stability and firmness of the mounting plate 5 during use.
[0029] Reference Figure 4 and Figure 5 The top of the pressure tank 3 is fixedly connected to an air inlet pipe 16, and a valve 15 is fixedly installed on the inner wall of the air inlet pipe 16. By setting the air inlet pipe 16 and the valve 15 in cooperation, the amount of medicine in the pipe 202 can be further increased to enter the tank 1, thereby avoiding the residue of medicine in the pipe 202 and ensuring that the medicine in the pipe 202 fully enters the tank 1.
[0030] Reference Figure 1 , Figure 2 and Figure 3 The surface of the tube 202 is provided with a scale 17. The tube 202 is made of transparent material. By making the tube 202 transparent, the user can easily observe the medicine in the tube 202. At the same time, under the function of the scale 17, the user can easily observe the dosage of the medicine in the tube 202, thereby making it convenient for the user to adjust the dosage.
[0031] Reference Figure 4 and Figure 5 Three anti-slip rings 14 are fixedly connected to the surface of the air inlet pipe 16. By setting the anti-slip rings 14, the anti-slip effect of the air inlet pipe 16 during use can be increased under the action of the anti-slip rings 14, thus achieving the purpose of increasing the anti-slip effect of the air inlet pipe 16.
[0032] Working Principle: When preparing a liquid formulation, a dispensing tank is required. To increase the user's ability to observe the dosage entering the tank 1 during addition, the user connects the formulation to be added through a pipe to a one-way valve 203. The user then activates the electric telescopic rod 201 via an external power supply and switch. The telescopic end of the electric telescopic rod 201 moves the push-pull rod 6, which in turn moves the push rod 204. The push rod 204 moves the circular plate 205, causing the rubber block 206 to move within the tube 202. This movement of the rubber block 206 creates a negative pressure within the tube 202, drawing the externally added formulation into the tube 202 through the one-way valve 203. At this point, the user can observe the dosage through the valve's design on the surface of the tube 202. The dosage is observed at scale 17 and then fed into tube 202. The user then activates the electric telescopic rod 201 again, causing the telescopic end of the electric telescopic rod 201 to retract, pushing the preparation into tube 202 into connecting tube 11. The preparation is then transported through connecting tube 11 into storage box 8, then into inlet pipe 9, and finally into tank 1. To prevent preparation residue in storage box 8 and inlet pipe 9, the user connects an external air compressor to storage box 8. During connection, the user connects the air compressor pipe to anti-slip ring 14 and opens valve 15 to allow all remaining preparation in storage box 8 and inlet pipe 9 to be transported into tank 1 by air pressure.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
