[0025] like Figure 1 and Figure 2 As shown, the cross partition 5 inside the solid medicine barrel 2 can be used to divide the space inside the solid medicine barrel 2, which is convenient for storing different types of medicines. In the solid medicine barrel 2, the inner bottom wall of the divided space is provided with a medicine discharge port. When it is rotated clockwise or counterclockwise to the top of the metering barrel 4, the solenoid valve 7 (point a) is opened to discharge the solid medicine into the interior of the metering barrel 4, which is convenient for switching different types of medicines for use, so as to facilitate flexible use.

[0026] A removable top cover 8 is provided on the top of the solid medicine barrel 2. The upper surface of the top cover 8 is provided with a feed port and is connected to the space corresponding to the cross partition 5. A marking layer 9 is provided at the edge of the cross plate of the bracket 1. The outer wall of the solid medicine barrel 2 is provided with a transparent layer 10, which is used in conjunction with the marking layer 9.

[0027] like Figure 2 As shown, the required medicine can be injected into the interior of the top cover 8 without opening the top cover 8 through the feed port on the upper surface of the top cover 8. When the solid medicine barrel 2 rotates and the transparent layer 10 is aligned with the marking layer 9, the medicine discharge port on its inner bottom wall is connected to the metering barrel 4.

[0028] The drive assembly includes a main gear 11 provided inside the horizontal plate of the bracket 1, a sub-gear 12 meshing with the main gear 11, and a drive wheel 13 and a drive wheel 2 14 used in conjunction with the sub-gear 12. The outer wall of the lower end of the solid medicine barrel 2 is provided with a toothed layer 30, which is meshed with the drive wheel 13. The top of the drive wheel 2 14 is fixedly connected to a vertical rod 15, and the top of the vertical rod 15 is meshed with a gear rod 16.

[0029] The stirring member includes a stirring rod 17 provided inside the liquid medicine barrel 3 and a bevel gear 28 fixedly connected to the top of the stirring rod 17. The other end of the gear rod 16 is meshed with the bevel gear 28. The lower surface of the horizontal plate of the bracket 1 is fixedly connected with a driving block 18, and the output end of the driving block 18 is fixedly connected to the main gear 11.

[0030] like Figure 6 As shown, starting the driving block 18 (with a motor as the power source) can drive the main gear 11 to rotate. A slide is provided inside the horizontal plate of the bracket 1, and the sub-gear 12 can move along the slide. When the sub-gear 12 moves to the left and meshes with the driving wheel 13, it synchronously drives the solid medicine barrel 2 to rotate. When the sub-gear 12 moves to the right and meshes with the driving wheel 2 14, it drives the vertical rod 15, the gear rod 16, the bevel gear 28 and the stirring rod 17 to rotate in sequence. The stirring rod 17 can be used to stir the medicine inside the liquid medicine barrel 3 to reduce the precipitation of particles in the liquid medicine and maintain the purification effect.

[0031] The metering module includes a baffle 19 disposed inside the bottom end of the metering cylinder 4 and a weighing sensor 20 disposed inside the baffle 19;

[0032] The power assembly includes an electric telescopic rod 21 provided at the edge of the bottom plate of the bracket 1, a connecting rod 22 provided at the output end of the electric telescopic rod 21, an auxiliary rod 23 fixedly connected to the end of the connecting rod 22 close to the electric telescopic rod 21, a spring 24 provided at the top of the auxiliary rod 23, and a bent rod 25 provided at the top of the spring 24. The top end of the bent rod 25 extends to the inside of the horizontal plate of the bracket 1 and is fixedly connected to the sub-gear 12.

[0033] In order to avoid manual adjustment of the position of the auxiliary gear 12, the following steps are taken:

[0034] When the electric telescopic rod 21 moves to the left, it can synchronously drive the connecting rod 22 and the baffle 19 to move to the left, and the baffle 19 is used to close the bottom of the metering cylinder 4, and the amount of solid medicine is measured by the weighing sensor 20. When the connecting rod 22 moves to the left, it synchronously drives the auxiliary rod 23 to move to the left. When the baffle 19 moves to the right, the bottom of the metering cylinder 4 can be opened, so that the solid medicine is discharged from the discharge pipe 6. Among them, the distance that the baffle 19 moves left and right is greater than the distance that the pinion 12 moves left and right in cooperation with the driving wheel 1 13 and the driving wheel 2 14. When the auxiliary rod 23 moves to the left, under the cooperation of the spring 24 and the bent rod 25, the pinion 12 is synchronously driven to move to the left. When the bent rod 25 drives the pinion 12 to move left and engages with the driving wheel 13, the baffle 19 does not move to the inside of the bottom end of the metering cylinder 4. At this time, the spring 24 is slowly in a stretched state, and the connecting rod 22 continues to move to the left. When the auxiliary rod 23 moves to the right, it performs the opposite movement as described above.

[0035] The upper surface of the liquid medicine barrel 3 is provided with a feed port and a metering rod 26 for measuring the amount of medicine. The side of the horizontal plate of the bracket 1 is fixedly connected with a display 27 and a control module, and is electrically connected to the weighing sensor 20 and the solenoid valve 7. The surface of the side plate of the bracket 1 is provided with a removable back plate 29, and the surface of the back plate 29 is provided with threaded holes for installation.

[0036] like Figure 1 and Figure 4 As shown, the metering rod 26 includes a buoyancy ball extending into the interior of the liquid medicine barrel 3. When the liquid medicine is injected into the liquid medicine barrel 3, the buoyancy ball can make the metering rod 26 rise. When the medicine is used, the solenoid valve 7 can be opened (point b) to discharge the medicine from the discharge pipe 6, thereby adding medicine to the water.

[0037] The weighing sensor 20 and the solenoid valve 7 can be controlled by the control module. Since the weighing sensor 20 is electrically connected to the display 27, when the weighing sensor 20 reaches the set weight, the value can be displayed on the display 27 for easy viewing. The weighing sensor 20, display 27, solenoid valve 7 and electric telescopic rod 21 mentioned above are existing well-known technologies and are only cited here. The specific structure is not described in detail.

[0038] The electrical components mentioned in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that performs control such as a computer.

[0039] In the present invention, the working steps of the device are as follows:

[0040] When in use, the top cover 8 is opened. Different types of medicines are stored in the solid medicine barrel 2, and liquid medicines are stored in the liquid medicine barrel 3. Then the top cover 8 is closed. The back plate 29 is fixed in the required position with bolts in advance. When it is necessary to add medicine to the water, a hose is provided at the bottom of the discharge pipe 6 to connect it to the water source that needs to be purified. The solenoid valve 7 (point a) or point b is opened, and the medicine is automatically discharged from the discharge pipe 6.

[0041] When the solid medicine barrel 2 is used and different medicines need to be replaced, the solenoid valve 7 (point a) is in a non-conducting state, and the electric telescopic rod 21 drives the pinion 12 to move to the left to engage with the drive wheel 13, and then starts the drive block 18 to drive the solid medicine barrel 2 to rotate. When the transparent layer 10 is compared with the marking layer 9, the drive block 18 is stopped, and then the solenoid valve 7 (point a) is opened, and the medicine automatically falls into the interior of the metering cylinder 4. When the weight of the medicine reaches the threshold set by the weighing sensor 20, an electrical signal is sent to the control module. At this time, the control module controls the solenoid valve 7 (point a) to close, and the electric telescopic rod 21 moves to the right, opening the bottom of the metering cylinder 4, and the medicine is automatically discharged from the discharge pipe 6, which facilitates the metering and delivery of medicines, thereby purifying the water source.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
