[0033] Specifically, the support frame 1 serves as the base of the entire device, providing a stable support structure. The water tank 2 is used to store the water for secondary water supply and is located at the top of the support frame 1 for easy collection and distribution of water. The water pump 3 is installed on the top of the water tank 2 and is used to suck and push the water into the water tank 2 to ensure that the water can flow to the users. The water inlet pipe 4 is connected to the input end of the water pump 3 and is used to guide the external water source into the water tank 2. The water output pipe 5 is connected to the output end of the water pump 3 and is used to transport the water into the water tank 2. The sewage discharge pipe 6 is used to discharge the cleaned sewage, and the water outlet pipe 8 is used to supply tap water. The motor 10 is used to provide power to drive the bidirectional threaded rod 11 to rotate. The bidirectional threaded rod 11 is used to drive the housing 12 to move. The housing 12 is used to install other components. The spring 13 is used to provide an elastic force. The scraper 14 is used to clean the scale on the inner bottom wall of the water tank 2, and the dropping component is used to drop the fungicide.

[0034] Referring to Figure 4 and Figure 5 , the dropping component includes a housing 15, the bottom of the housing 15 is fixedly connected to the top of the water tank 2, a motor 16 is fixedly connected to the outside of the housing 15, a cam 17 is fixedly connected to the output end of the motor 16, four corners inside the housing 15 are fixedly connected with tension springs 18, a sliding block 19 is slidably connected inside the housing 15, a check valve 1 20 is arranged on the inner bottom wall of the housing 15, and an input pipe 21 is fixedly connected to the outside of the housing 15.

[0035] Specifically, the housing 15 is used to support and install other components. The motor 16 is used to provide power to drive the cam 17 to rotate. The cam 17 is used to intermittently push the sliding block 19. The tension spring 18 is used to provide a pulling force. The sliding block 19 is used to squeeze the fungicide to enter the water tank 2. The check valve 1 20 is used to prevent the extruded fungicide from flowing back. The input pipe 21 is used to add the fungicide into the housing 15.

[0036] Referring to Figures 1 - 5, one end of the spring 13 is fixedly connected to the inner wall of the housing 12, the other end of the spring 13 is fixedly connected to the outside of the scraper 14, and the outside of the housing 12 is slidably connected to the inner wall of the water tank 2. A valve 7 is arranged inside the sewage discharge pipe 6, and a solenoid valve 9 is arranged inside the water outlet pipe 8. Both ends of the bidirectional threaded rod 11 are rotatably connected inside the water tank 2, and the end of the output pipe 5 far away from the water pump 3 is fixedly connected to the top of the water tank 2. The outside of the motor 10 is fixedly connected to the outside of the water tank 2, and the scraper 14 abuts against the inner bottom wall of the water tank 2. One end of the tension spring 18 is fixedly connected to the inner wall of the housing 15, and the other end of the tension spring 18 is fixedly connected to the outside of the sliding block 19. A check valve II 22 is arranged inside the input pipe 21, and the cam 17 abuts against the sliding block 19.

[0037] Specifically, one end of the spring 13 is fixed to the inner wall of the housing 12 and the other end is fixed to the outside of the scraper 14, which is used to provide an elastic force to push the scraper 14 to automatically extend when the scraper 14 wears. The outside of the housing 12 slides on the inner wall of the water tank 2, so that the housing 12 will not rotate together with the bidirectional threaded rod 11. The valve 7 is arranged inside the sewage discharge pipe 6 to control the switch of sewage discharge. The solenoid valve 9 is arranged inside the water outlet pipe 8 to control the supply switch of tap water. Both ends of the bidirectional threaded rod 11 rotate inside the water tank 2 to make the rotation of the bidirectional threaded rod 11 more stable. The end of the output pipe 5 far away from the water pump 3 is fixedly connected to the top of the water tank 2 to make the tap water pumped by the water pump 3 enter the water tank 2. The outside of the motor 10 is fixed to the outside of the water tank 2 to make the motor 10 more stable during operation. The scraper 14 abuts against the inner bottom wall of the water tank 2 to clean the scale on the inner bottom wall of the water tank 2 when the scraper 14 moves. One end of the tension spring 18 is fixed to the inner wall of the housing 15 and the other end is fixed to the outside of the sliding block 19 to provide a pulling force to pull the sliding block 19 back to its original position when the cam 17 does not push the sliding block 19. The check valve II 22 is arranged inside the input pipe 21 to prevent the backflow of the inhaled fungicide. The cam 17 abuts against the sliding block 19 to make the cam 17 intermittently push the sliding block 19 inside.

[0038] Working principle: When the water tank 2 is in use, start the water pump 3. The water pump 3 extracts tap water through the water inlet pipe 4, and then inputs the tap water into the interior of the water tank 2 through the output pipe 5 for pressurization. Open the solenoid valve 9, and the tap water supplies tap water to users through the water outlet pipe 8. When it is necessary to clean the scale in the water tank 2, turn off the water pump 3 and the solenoid valve 9. The water pump 3 stops pumping water into the interior of the water tank 2, and the water outlet pipe 8 stops discharging water. Start the motor 10. The motor 10 drives the double-threaded screw rod 11 to rotate inside the water tank 2. The double-threaded screw rod 11 drives the two scrapers 14 to move towards the middle of the water tank 2. The scrapers 14 abut against the inner bottom wall of the water tank 2 to clean the scale. After scraping off the scale, open the valve 7, and the sewage is discharged from the sewage pipe 6. When it is necessary to add a bactericide, start the motor 16. The motor 16 drives the cam 17 to rotate. The cam 17 intermittently pushes the sliding block 19 to slide inside the housing 15 by abutting against the sliding block 19. The sliding block 19 slides to pull the tension spring 18, and the tension spring 18 generates a pulling force. When the cam 17 does not push the sliding block 19, the tension spring 18 pulls the sliding block 19 back to its original position. When the sliding block 19 slides, the bactericide is squeezed into the interior of the water tank 2 from the check valve 1 20, and at the same time, the bactericide is inhaled from the input pipe 21. Because of the check valve 2 22, the input pipe 21 can only inhale the bactericide and cannot extrude the bactericide.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
