[0018] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0019] Reference Figure 1-4 An automatic quantitative filling device according to an embodiment of the present invention includes a water storage tank 1. The inner side of the water storage tank 1 adopts a hollow structure. Fixing blocks 25 are fixedly connected to the left and right ends of the inner side of the water storage tank 1. A sliding groove 17 is opened in the inner side of the fixing block 25. A screw 16 is rotatably connected to the inner center of the sliding groove 17. Sliding rods 11 are fixedly connected to the inner ends of the sliding groove 17. A slider 15 is slidably connected to the inner side of the sliding groove 17. The slider 15 is threadedly connected to the screw 16. The slider 15 is slidably connected to the sliding rod 11. A connecting frame 10 is fixedly connected to the inner side of the slider 15. A water level detector 9 is fixedly connected to the lower end of the connecting frame 10. A motor 13 is fixedly connected to the center of the front end of the water storage tank 1. The output end of the motor 13 passes through the water storage tank 1 and is fixedly connected to the screw 16 via a coupling. The screw 16 and the slide rod 11 are made of reinforced polyamide material, which has good water resistance and strong mechanical strength during use. The water level detector 9 can emit laser light to the lower end in real time during use. The distance between the laser light and the water level is determined by the reflection of the laser light. When the distance is less than 5 mm, a signal will be emitted to the outside. After the outer antenna 2 receives the signal, it will translate the instruction to the controller 24 to complete the instruction transmission.

[0020] A hole is located at the center of the lower end of the water tank 1, and a drain outlet 5 is fixedly connected to the inside of the hole. A water inlet pipe 3 is fixedly connected to the left side of the lower end of the water tank 1. A cylinder 6 is fixedly connected to the lower right end of the water tank 1. A piston rod 19 is located at the center of the inside of the cylinder 6. A connecting plate 26 is fixedly connected to the lower end of the piston rod 19. A sealing plug 12 is fixedly connected to the left side of the upper end of the connecting plate 26. The sealing plug 12 cooperates with the drain outlet 5. A connecting rod 21 is fixedly connected to the right side of the lower end of the cylinder 6. A pressure switch 20 is located on the left side of the upper end of the connecting rod 21. When the controller 24 receives a signal transmitted by the water level detector 9, it will transmit a signal to the cylinder 6 at the lower end through the antenna, causing the cylinder 6 to move downward, thereby causing the sealing plug 12 to disengage from the inside of the drain outlet 5. The water inside the water tank 1 flows down... As the water flows out through drain 5, when the sealing plug 12 and the lower connecting plate 26 move, they will touch the pressure-activated switch 20 at the upper end of the connecting rod 21. At this time, the pressure-activated switch 20 is pressed, which sends a signal to the electronic valve 18, causing the electronic valve 18 to be closed. At this time, the water inlet pipe 3 stops flowing in. When the water inside the water tank 1 is drained, the water level detector 18 detects the maximum distance. At this time, another signal is emitted, which is received by the antenna 2 and sent through the controller 24. This causes the cylinder 6 to drive the piston rod 19 to move upward, causing the sealing plug 12 to block the drain 5 and the pressure-activated switch 20 to be loosened. At this time, the electronic valve 18 on the left side of the water inlet pipe 3 is open, and the water inlet pipe 3 supplies water to the water tank 1.

[0021] A circular hole is provided at the center of the upper end of the water storage tank 1. A threaded hole 8 is provided inside the circular hole. A sealing cover 4 is fitted inside the circular hole. A connecting thread 14 is provided on the outside of the sealing cover 4. The connecting thread 14 fits with the threaded hole 8. A handle 7 is fixedly connected at the center of the upper end of the sealing cover 4. An electronic valve 18 is provided at the lower left end of the drain outlet 5. When it is necessary to clean the inside of the water storage tank 1, the handle 7 is turned so that the connecting thread 14 next to the sealing cover 4 and the threaded hole 8 rotate in opposite directions, thereby removing the sealing cover 4 and cleaning the water storage tank 1.

[0022] A controller 24 is fixedly connected to the center of the lower front of the water tank 1. An antenna 2 is fixedly connected to the upper left side of the controller 24. A display screen 22 is fixedly connected to the upper front of the controller 24. Multiple buttons 23 are provided at the front of the controller 24. When in use, the display screen 22 can display the height of the water level inside and the quantitative position. Pressing the buttons 23 can control the rotation of the motor 13, thereby quantitatively adjusting the water level inside the water tank 1.

[0023] Working principle: In use, rotate the water supply pipe to the inlet pipe 3, press button 23 to make the motor 13 rotate, and drive the lower screw 16 to rotate synchronously under the action of the coupling. Under the rotation of the screw 16, the slider 15 connected by the outer thread slides along the inner side of the slide groove 17 on the outer side of the slide rod 11, thereby driving the connecting frame 10 connected to the inner side of the slider 15 to move. When the connecting frame 10 moves, the water level detector 9 at its lower end moves synchronously. By adjusting the height of the water level detector 9, the water level inside the water tank 1 is quantitatively measured. When the quantitative measurement is completed, the water inside the inlet pipe 3 will replenish the water tank 1. When the quantitative threshold is reached, the water level detector 9 will send a signal to the controller 2. 4. Start cylinder 6, which pushes piston rod 19 downward. Piston rod 19 moves downward, pushing connecting plate 26 and front sealing plug 12. When sealing plug 12 moves downward, the inside of drain port 5 is open. At this time, water inside water tank 1 will flow out along drain port 5 to complete filling. When connecting plate 26 moves downward, it will contact pressure switch 20. At this time, electronic valve 18 will receive a signal and close, thereby cutting off the water supply inside water tank 1 and avoiding water waste. After the water is drained, water level detector 9 will send a signal, causing sealing plug 12 to contact drain port 5 and pressure switch 20 to loosen and electronic valve 18 to open, completing the water supply to water tank 1.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
