[0002] Liquid medicine storage tanks are widely used in the medical industry. Traditional liquid medicine storage tanks mainly include a tank body with a sealed upper cover, a liquid medicine inlet on the top of the tank body, and a liquid medicine outlet at the bottom of the tank body. The finished liquid medicine is placed in the liquid medicine storage tank to facilitate subsequent filling, or the intermediates of liquid medicine production are placed inside it and used as a buffer or transition tank.

[0003] When filling and discharging liquid, the existing liquid medicine storage tanks cannot fully receive the liquid medicine due to the narrow mouth of the bottle, which will cause the liquid medicine to splash. When sealing, most of them use a sealing plug to plug into the bottle mouth, which will squeeze out the liquid medicine. The change of liquid medicine pressure in the sealed environment will cause the liquid medicine to spray out when the liquid outlet is opened, and the cylindrical liquid outlet will have too much liquid medicine remaining on the outer wall after pouring the liquid medicine. These situations will cause leakage, easily pollute the surrounding environment, and reduce the utilization rate of the liquid medicine. Utility Model Content

[0026] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the scheme of the utility model will be further described below. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0027] The following description sets forth many specific details to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the implementation methods in the specification are only part of the implementation methods of the present invention, rather than all of the implementation methods.

[0028] Combination Figures 1 to 6 As shown, the liquid medicine receiving device for avoiding liquid leakage provided by the embodiment of the utility model includes a shell 1, a liquid inlet sealing mechanism 2, which is installed at the upper end of the liquid inlet of the shell 1, and when the larger end of the liquid inlet sealing mechanism 2 is buckled downward on the upper end of the liquid inlet of the shell 1, it plays a sealing role, and when the smaller end of the liquid inlet sealing mechanism 2 is buckled downward on the upper end of the liquid inlet of the shell 1, it plays a drainage role, a shell inner cavity pressure regulating mechanism 4, which is fixedly connected to the shell 1, a pressure sensor 5, which is installed at the lower end of the inner wall of the shell 1, a controller 3, and the controller 3 is electrically connected to the pressure sensor 5 and the shell inner cavity pressure regulating mechanism 4 respectively, and a liquid outlet mechanism 9, which is installed on a liquid level tube connected to the shell 1, and is used to control the flow rate of the liquid outlet, and the liquid outlet of the liquid outlet mechanism 9 is conical.

[0029] Therefore, the contact area with the liquid surface is increased by the liquid inlet sealing mechanism during canning to prevent the liquid medicine from splashing, and the liquid inlet is sealed after canning. The pressure regulating mechanism in the inner cavity of the shell allows the sealed environment in the device to maintain a stable pressure, and the liquid medicine can be discharged at a controlled flow rate by the liquid outlet mechanism, avoiding excessive liquid medicine remaining on the outer wall after pouring, thereby avoiding leakage and improving the utilization rate of the liquid medicine.

[0030] In some embodiments, Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the liquid sealing mechanism 2 includes a funnel 21, an iron cover 22, an electromagnet 23, a rechargeable battery 24 and a sealing ring 25. The inner wall of the funnel 21 is threadedly connected to the upper end of the liquid inlet of the shell 1, the iron cover 22 is hinged to the upper surface of the thin end of the funnel 21, the electromagnet 23 is installed in the upper surface of the thin end of the funnel 21, the rechargeable battery 24 is installed inside the thin end of the funnel 21, the rechargeable battery 24 is electrically connected to the electromagnet 23, and the sealing ring 25 is installed on the part of the iron cover 22 that contacts the liquid inlet. The electromagnet 23 is used to adsorb the iron cover 22 to seal the liquid inlet.

[0031] A sealing ring 25 is installed at the contact portion between the funnel 21 and the iron cover 22 .

[0032] Therefore, when filling the canned medicine, the iron cover 22 is opened, and then the thin end of the funnel 21 is tightened downwardly with the shell 1 to increase the contact area between the liquid inlet and the medicine to prevent the medicine from splashing. After the infusion is completed, the thin end of the funnel 21 is tightened upwardly with the shell 1, the iron cover 22 and the funnel 21 are buckled together, the rechargeable battery 24 is turned on, and the electromagnet 23 is energized to generate magnetism, the iron cover 22 is adsorbed, and the liquid inlet is sealed. This sealing method does not require the sealing mechanism to enter the medicine to change the volume of the medicine and then overflow to the outside of the device. A sealing ring 3 is installed at the contact portion between the funnel 21 and the iron cover 22 to further increase the sealing performance.

[0033] In some embodiments, Figure 1 and Figure 2 As shown, the shell inner cavity pressure regulating mechanism 4 includes a convex shell 41, a cylinder 42 and a baffle 43. The convex shell 41 is fixedly connected to the outer wall of the shell 1, the cylinder 42 is installed at one end of the convex shell 41 away from the shell 1, and the baffle 43 is installed on the output end of the cylinder 42. The side wall of the baffle 43 is sealed to the inner wall of the convex shell 41 close to the shell 1.

[0034] Therefore, when the pressure sensor 5 detects that the pressure in the device changes to a preset value, it transmits a signal to the external controller, starts the cylinder 42 to move the baffle outward, increases the volume of the liquid medicine in the device, and restores the pressure in the device to the pressure at the time of canning, thereby avoiding excessive pressure in the device causing the liquid medicine to spray out through the liquid outlet when the device is opened.

[0035] In some embodiments, Figure 1 and Figure 2 As shown, a visible L-shaped tube 8 is fixedly connected to one side of the shell 1 . The visible L-shaped tube 8 is a liquid level tube of the shell 1 , and a liquid outlet mechanism 9 is installed at the upper end of the visible L-shaped tube 8 .

[0036] Therefore, when the medicine liquid is being canned, as the medicine liquid enters the device, the liquid level of the visible L-shaped tube 8 also rises. Since it is on the same horizontal plane as the liquid inlet, the canning is stopped when the liquid level of the visible L-shaped tube 8 is full, and the capacity in the device can be clearly observed, thereby preventing leakage caused by canning when the device capacity is full.

[0037] In some embodiments, Figure 1 and Figure 2 As shown, the liquid outlet mechanism 9 includes a gate valve 91 and a conical liquid outlet 92 . The conical liquid outlet 92 is opened at the upper end of the visible L-shaped tube 8 . The gate valve 91 is installed on the upper surface of the visible L-shaped tube 8 . The gate valve 91 is used to control the liquid outlet of the conical liquid outlet 92 .

[0038] Therefore, when the medicine liquid is to be transported to the outside, the door valve 91 is opened to discharge the medicine liquid from the conical liquid outlet 92. The door valve 91 can control the flow rate. Since the metering requirements for the use of the medicine liquid are relatively precise, the flow rate can be controlled as needed to prevent pouring too quickly. Compared with the ordinary cylindrical outlet, the conical liquid outlet 92 can reduce the amount of medicine liquid remaining on the outer wall of the device after pouring.

[0039] In some embodiments, Figure 1 and Figure 2 As shown, a filter screen 7 is transversely installed on the inner wall of the shell 1 , and the filter screen 7 is located above the connection point between the visible L-shaped tube 8 and the shell 1 .

[0040] Therefore, after the liquid medicine is left standing for a period of time, precipitation may be generated, and if it is not processed, the quality of the liquid medicine will be affected. The filter screen 7 can process the generated precipitation, and the processed liquid medicine is discharged to the outside through the visible L-shaped tube 8.

[0041] In some embodiments, Figure 1 and Figure 2 As shown, a cooling rod 6 is installed on the inner wall of the shell 1, and the cooling rod 6 is located above the pressure regulating mechanism 4 in the inner cavity of the shell.

[0042] Therefore, when the outside temperature is high, the temperature of the medicine liquid will also rise, and it may deteriorate and lose its efficacy. By installing a refrigeration device, the medicine liquid in the device can be kept at an appropriate temperature.

[0043] The following is combined with Figure 1-6 Describe a specific embodiment of the utility model:

[0044] like Figure 1-Figure 6 As shown, it includes a shell 1, a liquid inlet sealing mechanism 2, which is installed at the upper end of the liquid inlet of the shell 1. When the larger end of the liquid inlet sealing mechanism 2 is buckled downward on the upper end of the liquid inlet of the shell 1, it plays a sealing role. When the smaller end of the liquid inlet sealing mechanism 2 is buckled downward on the upper end of the liquid inlet of the shell 1, it plays a drainage role. The shell cavity pressure regulating mechanism 4 is fixedly connected to the shell 1, the pressure sensor 5 is installed at the lower end of the inner wall of the shell 1, the controller 3, the controller 3 is electrically connected to the pressure sensor 5 and the shell cavity pressure regulating mechanism 4 respectively, and the liquid outlet mechanism 9 is installed on the liquid level pipe connected to the shell 1, and is used to control the flow rate of the liquid outlet. The liquid outlet of the liquid outlet mechanism 9 is conical, as shown in FIG. Figure 1 and Figure 2As shown, the shell cavity pressure regulating mechanism 4 includes a convex shell 41, a cylinder 42 and a baffle 43. The convex shell 41 is fixedly connected to the outer wall of the shell 1, the cylinder 42 is installed at the end of the convex shell 41 away from the shell 1, the baffle 43 is installed on the output end of the cylinder 42, and the side wall of the baffle 43 is sealed with the inner wall of the convex shell 41 at one end close to the shell 1. The liquid outlet mechanism 9 includes a gate valve 91 and a conical liquid outlet 92. The conical liquid outlet 92 is opened at the upper end of the visible L-shaped tube 8. The gate valve 91 is installed on the upper surface of the visible L-shaped tube 8. The gate valve 91 is used to control the liquid outlet of the conical liquid outlet 92.

[0045] In actual use, when filling the liquid medicine, the iron cover 22 is opened, and then the thin end of the funnel 21 is tightened downwardly with the shell 1 to increase the contact area between the liquid inlet and the liquid medicine to prevent the liquid medicine from splashing. After the infusion is completed, the thin end of the funnel 21 is tightened upwardly with the shell 1, the iron cover 22 is buckled with the funnel 21, and the rechargeable battery 24 is turned on to energize the electromagnet 23 to generate magnetism, adsorb the iron cover 22, and seal the liquid inlet. This sealing method does not require the sealing mechanism to enter the liquid medicine to change the volume of the liquid medicine, and then overflow to the outside of the device. When the pressure in the device changes to a preset value through the pressure regulating mechanism 4 in the inner cavity of the shell, a signal is transmitted to the outside The controller 3 starts the cylinder 42 to move the baffle outward, increasing the volume of the liquid medicine in the device and restoring the pressure in the device to the pressure when the device is canned, thus avoiding excessive pressure in the device causing the liquid medicine to spray out through the liquid outlet when the device is opened. When the liquid medicine is to be transported to the outside, the door valve 91 is opened to discharge the liquid medicine from the conical liquid outlet 92. The door valve 91 can control the flow rate. Since the metering requirements for the use of the liquid medicine are relatively precise, the flow rate can be controlled as needed to prevent pouring too quickly. Compared with the ordinary cylindrical outlet, the conical liquid outlet 92 can reduce the liquid medicine remaining on the outer wall of the device after pouring, thereby avoiding the occurrence of leakage and improving the utilization rate of the liquid medicine.
