Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3The utility model provides an embodiment: a medicine metering device based on a metering tank, comprising a device support frame 1, a visualization control module 3, a liquid metering tank body 4 and a solenoid valve 10, a high-precision electronic scale 2 is fixedly installed in the middle of the top of the device support frame 1, a top packaging cover 5 is threadedly connected to the top of the liquid metering tank body 4, a pressure balance pipe 6 is fixedly connected to the top of the liquid metering tank body 4, and a dust-proof filter plug 7 is threadedly connected to the end of the pressure balance pipe 6 away from the liquid metering tank body 4, a discharge pipe 8 is fixedly connected to the bottom end of the outer side of the liquid metering tank body 4, and a manual valve 9 is fixedly installed on the discharge pipe 8, the liquid metering tank body 4 is respectively connected with the pressure balance pipe 6 and the discharge pipe 8, when the liquid metering tank body 4 discharges liquid through the discharge pipe 8, the pressure inside the liquid metering tank body 4 is reduced due to the discharge of liquid, and the external air is filtered by the dust-proof filter plug 7 and then transported to the inside of the liquid metering tank body 4 through the pressure balance pipe 6, thereby achieving the balance of the internal and external pressures of the liquid metering tank body 4, thereby ensuring that the discharge pipe 8 can discharge liquid smoothly.

[0020] The bottom end of the liquid measuring tank body 4 is fixedly connected to a bottom support frame 11, an observation port 12 is provided through the outer side of the liquid measuring tank body 4, a transparent glass observation plate 13 is fixedly installed on the inner side of the observation port 12, and a scale line 14 is provided on the outer side of the liquid measuring tank body 4 near the transparent glass observation plate 13. The amount of liquid inside the liquid measuring tank body 4 can be observed through the transparent glass observation plate 13. At the same time, according to the amount of liquid required for the day, the scale line 14 can be used to roughly understand whether liquid needs to be added.

[0021] The visualization control module 3 is electrically connected to the high-precision electronic scale 2 and the solenoid valve 10 respectively. The visualization control module 3 conveniently controls the opening and closing of the solenoid valve 10 by receiving the weight information transmitted in real time by the high-precision electronic scale 2, thereby accurately controlling the discharge amount of the liquid.

[0022] The visualization control module 3 is fixedly installed on the top of the device support frame 1, and the visualization control module 3 is located on the outside of the high-precision electronic scale 2. A PLC controller is provided inside the visualization control module 3. The user can conveniently set the program and observe the real-time status of the discharge through the display screen on the visualization control module 3.

[0023] The bottom end of the bottom support frame 11 is close to the top of the high-precision electronic scale 2, and the liquid measuring tank body 4 is placed in the middle of the top of the high-precision electronic scale 2 through the bottom support frame 11. The liquid measuring tank body 4 is weighed by the high-precision electronic scale 2, and the high-precision electronic scale 2 transmits the weight of the liquid measuring tank body 4 to the visualization control module 3 in real time, and controls the opening and closing of the solenoid valve 10 through the preset program in the visualization control module 3.

[0024] The solenoid valve 10 is fixedly installed at one end of the discharge pipe 8 away from the liquid metering tank body 4, and the manual valve 9 is located between the liquid metering tank body 4 and the solenoid valve 10. When in use, the manual valve 9 is normally open. The manual valve 9 is closed when the use is completed on the day or when it is not used for a long time, thereby avoiding leakage caused by damage to the solenoid valve 10.

[0025] Working principle: During use, first set the automatic control program through the visual control module 3, and set different control instructions according to the weight of the liquid required in different situations, and then observe the amount of liquid inside the liquid measuring tank body 4 through the scale line 14 on the outside of the liquid measuring tank body 4 and the transparent glass observation plate 13. When the amount of liquid inside the liquid measuring tank body 4 is not enough to meet the daily usage, open the top sealing cover 5 through external force and pour the liquid into the liquid measuring tank body 4. After the liquid is loaded, tighten the top sealing cover 5 to the top of the liquid measuring tank body 4 through external force, and then the high-precision electronic scale 2 transmits the weight of the liquid measuring tank body 4 to the visual control module 3 in real time. The initial weight of the liquid metering tank body 4 is set. When the liquid needs to be discharged, the container for receiving the liquid is placed directly below the end of the discharge pipe 8 away from the liquid metering tank body 4, and then the manual valve 9 is opened by external force, and the corresponding control instruction is selected through the visual control module 3. The visual control module 3 controls the solenoid valve 10 to open, and the liquid in the liquid metering tank body 4 is discharged through the discharge pipe 8 and falls into the container. At the same time, the high-precision electronic scale 2 transmits the weight data of the liquid metering tank body 4 to the visual control module 3 in real time. When the weight reduction of the liquid metering tank body 4 reaches a predetermined value, the visual control module 3 controls the solenoid valve 10 to close. After the use of the day is over, the manual valve 9 is closed by external force to prevent liquid leakage.
