Technical Field

[0002] As people's lives become increasingly integrated with smart technology and automation, issues such as environmental protection and energy shortages are receiving more attention. In particular, the upgrading of public places such as public restrooms with automated, energy-saving, and environmentally friendly equipment is becoming increasingly important. Currently, most areas in my country still use traditional hand-operated toilet flushers.

[0003] The invention patent with publication number CN208137060U discloses a water-saving and energy-efficient system for smart public toilets. The system includes a public toilet, a water tank, and a control module. The water tank is located inside the public toilet and is fixedly connected to it. The water tank includes a battery, an inlet pipe, and a flushing pipe. The battery includes an inverter and a solar panel. The control module includes an infrared sensor, a first solenoid valve, a second solenoid valve, a data analysis module, and a timer. The data analysis module also includes a data memory module. This water-saving and energy-efficient system for smart public toilets reduces electricity consumption and water usage, achieving the goal of water and energy conservation in public toilets. It has significant utilization and promotional value.

[0004] In existing public toilet timed flushing devices, the water circuit is controlled by a solenoid valve. Tap water is transported through pipes, and dirt and rust formed on the pipes will enter the solenoid valve along with the pipes. The dirt will cause problems such as blockage of the diaphragm in the solenoid valve or failure to close tightly, affecting the service life of the solenoid valve and the timed flushing action of the public toilet. In order to solve the above problems, this application proposes an automatic timed flushing device for public toilets. Utility Model Content

Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0027] like Figure 1-4 As shown, the present invention proposes an automatic timed flushing device for public toilets, including a timed controller 1 and a solenoid valve 5. The solenoid valve 5 is located on one side of the timed controller 1. A three-way connecting pipe 12 is threadedly connected to the top of the solenoid valve 5. A rotor booster pump 6 is connected to the top of the three-way connecting pipe 12. The discharge end of the rotor booster pump 6 is connected to the three-way connecting pipe 12.

[0028] The suction end of the rotor booster pump 6 is threadedly connected to a water guide pipe 7. The cross-section of the water guide pipe 7 is a right-angle structure, and an external filter 8 is connected to the end of the water guide pipe 7.

[0029] The bottom of the external filter 8 is threadedly connected to a filter cartridge 9, and the filter cartridge 9 is provided with an outer shell 10.

[0030] It should be noted that the external filter 8 is connected to the water supply equipment. Tap water is injected into the space between the filter cartridge 9 and the outer casing 10 of the external filter 8. The tap water passes through the mesh on the surface of the filter cartridge 9 and enters the filter cartridge 9. Impurities in the tap water are filtered out by the filter cartridge 9 and trapped between the filter cartridge 9 and the outer casing 10. Then, the tap water is guided into the rotor booster pump 6 by the water guide pipe 7. The rotor booster pump 6 can pressurize the tap water to prevent the pressure from dropping when the tap water passes through the external filter 8 and to prevent the water supply pressure from being too low, which would affect the automatic flushing effect of the public toilet. The timer controller 1 can control the solenoid valve 5 and the rotor booster pump 6 to open simultaneously at set times. The system can be turned on or off to achieve automatic timed flushing of the public toilet. After opening the slag discharge valve 11, the impurities filtered out of the external filter 8 can be quickly discharged. At the same time, the timer controller 1 controls the solenoid valve 5 to close, and then the water supply to the external filter 8 is turned off. The water supply equipment is connected to the backwash connection pipe 14 through the water pipe, and the rotor booster pump 6 is turned on. The rotor booster pump 6 can supply water from both ends, so that the tap water can be injected back into the filter cartridge 9 inside the external filter 8 through the rotor booster pump 6. Opening the slag discharge valve 11 can discharge the tap water in the outer shell 10, which can realize the rapid backwashing of the filter cartridge 9, so as to achieve rapid backwashing of the external filter 8 and ensure the filtration effect of tap water.

[0031] In this embodiment, as Figure 3 As shown, the timer controller 1 has a display panel 2 and control buttons 3 mounted on its surface, with the display panel 2 located above the control buttons 3.

[0032] It should be noted that the display panel 2 and control buttons 3 work together to adjust the timer controller 1.

[0033] In this embodiment, as Figure 1 As shown, the timing controller 1 has a connecting seat 4 integrally formed on its side wall, and the solenoid valve 5 is fixed to the timing controller 1 through the connecting seat 4.

[0034] It should be noted that the solenoid valve 5 is fixed to the timer controller 1 via the connecting seat 4.

[0035] In this embodiment, as Figure 4 As shown, the bottom of the outer shell 10 is provided with a drain port, and a slag discharge valve 11 is threadedly connected to the drain port.

[0036] It should be noted that opening the slag discharge valve 11 can quickly discharge impurities from the outer casing 10.

[0037] In this embodiment, as Figure 3As shown, the end of the three-way connecting pipe 12 is connected to a backwash valve 13, which is installed between the solenoid valve 5 and the rotor booster pump 6. The end of the backwash valve 13 is connected to a backwash connecting pipe 14.

[0038] It should be noted that the water supply equipment is connected to the backwash connection pipe 14 through a water pipe, and the rotor booster pump 6 is turned on. The rotor booster pump 6 can supply water from both ends, so that the tap water can be injected back into the filter cartridge 9 inside the external filter 8 through the rotor booster pump 6. The slag discharge valve 11 is opened to discharge the tap water in the outer shell 10, so as to realize the rapid backwashing of the filter cartridge 9, thereby achieving rapid backwashing of the external filter 8 and ensuring the filtration effect of tap water.

[0039] The working principle and usage process of this utility model are as follows: The external filter 8 is connected to the water supply equipment. Tap water is injected into the space between the filter cartridge 9 and the outer shell 10 of the external filter 8. The tap water passes through the mesh on the surface of the filter cartridge 9 and enters the filter cartridge 9. Impurities in the tap water can be filtered through the filter cartridge 9. The filtered impurities are blocked between the filter cartridge 9 and the outer shell 10. Then, the tap water is guided into the rotor booster pump 6 through the water guide pipe 7. The rotor booster pump 6 can pressurize the tap water to prevent the tap water from depressurizing when passing through the external filter 8 and to prevent the water supply pressure from being too low, which would affect the automatic flushing effect of the public toilet. The timer controller 1 can control the solenoid valve 5 and the rotor booster pump at regular intervals. Pump 6 is turned on or off simultaneously to achieve automatic timed flushing of the public toilet. After the slag discharge valve 11 is opened, the impurities filtered out of the external filter 8 can be quickly discharged. At the same time, the timer controller 1 controls the solenoid valve 5 to close, and then the water supply to the external filter 8 is turned off. The water supply equipment is connected to the backwash connection pipe 14 through the water pipe, and the rotor booster pump 6 is turned on. The rotor booster pump 6 can supply water from both ends, so that the tap water can be injected back into the filter cartridge 9 inside the external filter 8 through the rotor booster pump 6. Opening the slag discharge valve 11 can discharge the tap water in the outer shell 10, which can realize the rapid backwashing of the filter cartridge 9, so as to achieve rapid backwashing of the external filter 8 and ensure the filtration effect of tap water.
