Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid medicine dispensing, and in particular to a liquid medicine dispensing device with a buffer function. Background Technology
[0002] Before filling liquids, the bottles need to be cleaned to ensure cleanliness. Neutral detergents and other chemical solutions are usually used to clean the bottles. The chemical solution is usually prepared and stored in a chemical solution container before use so that it can be used at any time.
[0003] When adding the medicine into the medicine tank, it is necessary to avoid excessive impact force. High-speed impact may cause wear on the metal materials of the inner wall or accessories of the tank, resulting in metal particles falling off and contaminating the medicine. Moreover, high-pressure impact may damage the tank interface, flange or sealing ring, causing the medicine to leak out. Utility Model Content
[0004] In view of this, the present invention provides a medicine filling device with a buffer function. The main technical problem to be solved is to increase the medicine filling buffer structure to avoid the large impact force during medicine filling, which would cause wear of the metal material on the inner wall of the tank and pipeline vibration, resulting in pipeline leakage.

[0006] By adopting the above technical solution, the medicine is injected from the inlet pipe during use. After entering the inlet pipe, the medicine will enter the filling tank along the tangential direction of the inner wall of the filling tank, causing the medicine to rotate along the inner wall of the filling tank, absorbing the impact force during the injection. Afterwards, the medicine stored in the filling tank will enter the medicine tank through the connecting pipe for storage. In addition, when there is too much medicine in the filling tank, the excess medicine will enter the medicine tank through the anti-overflow pipe at the top of the filling tank, which has an emergency effect and prevents excess medicine from overflowing.
[0007] As a further description of the above technical solution:
[0008] The top of the medicine tank has a feed inlet, and an end cap is movably connected to the inside of the feed inlet.
[0009] By adopting the above technical solution, materials can be added into the medicine tank by opening the end cap at the feed port, the medicine tank can be cleaned, and the medicine in the medicine tank can be extracted to detect its concentration.
[0010] As a further description of the above technical solution:
[0011] A bracket is fixedly connected to the bottom of the filling tank, and the bottom of the bracket is fixedly connected to the upper surface of the medicine tank.
[0012] By adopting the above technical solution, the liquid medicine tank is installed on top of the filling tank using a bracket.
[0013] As a further description of the above technical solution:
[0014] A flow meter is installed on the connecting pipe.
[0015] By adopting the above technical solution, the state of the liquid medicine flowing in the connecting pipe can be detected by the flow meter.
[0016] As a further description of the above technical solution:
[0017] The bottom of the medicine tank is fixedly connected to a discharge pipe, and a valve is installed at the bottom of the discharge pipe.
[0018] By adopting the above technical solution, it is easy to drain the medicine from the medicine tank.
[0019] As a further description of the above technical solution:
[0020] A pressure relief pipe is fixedly connected to the bottom of the medicine tank. The top end of the pressure relief pipe is located inside the medicine tank, and the bottom end of the pressure relief pipe is located below the medicine tank.
[0021] By adopting the above technical solution, excess medicine in the medicine tank can be discharged, so that the amount of medicine in the medicine tank is kept at a certain level, which facilitates the storage of medicine in the medicine tank.
[0022] By employing the above technical solution, the medicine dispensing device with buffering function of this utility model has at least the following beneficial effects:
[0023] 1. Compared with the prior art, this buffered liquid dispensing device injects liquid medicine through an inlet pipe. After entering the inlet pipe, the liquid medicine enters the dispensing tank along the tangential direction of the inner wall of the dispensing tank, causing the liquid medicine to rotate along the inner wall of the dispensing tank, absorbing the impact force during dispensing. Afterwards, the liquid medicine stored in the dispensing tank will enter the liquid medicine tank through a connecting pipe for storage. Furthermore, when there is too much liquid medicine in the dispensing tank, the excess liquid medicine will enter the liquid medicine tank from the overflow prevention pipe at the top of the dispensing tank, which plays an emergency role and prevents excess liquid medicine from overflowing.

[0034] Working principle: When in use, the medicine is injected through the inlet pipe 7. After entering the inlet pipe 7, the medicine will enter the filling tank 4 along the tangential direction of the inner wall of the filling tank 4, causing the medicine to rotate along the inner wall of the filling tank 4, absorbing the impact force during the injection. Afterwards, the medicine stored in the filling tank 4 will enter the medicine tank 2 through the connecting pipe 8 for storage. In addition, when there is too much medicine in the filling tank 4, the excess medicine will enter the medicine tank 2 through the anti-overflow pipe 6 at the top of the filling tank 4, which has an emergency effect and prevents excess medicine from overflowing.
