BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following is a further description of a safety device for preventing electric water heater leakage according to the present invention in conjunction with the accompanying drawings and specific embodiments.

[0014] Figure 1 The present invention is a schematic structural diagram of a safety device for preventing leakage of electric water heaters. DETAILED DESCRIPTION

[0015] like Figure 1 As shown, a safety device for preventing leakage of electric water heater of the present invention is composed of a power supply controller 10, a fluid mechanical control mechanism 20 and a signal transmitter and receiver 30. The power supply controller 10 and the fluid mechanical control mechanism 20 are connected by the signal transmitter and receiver 30. The power supply controller 10 is provided with an insulating base 11, and an upper electrical contact panel 12 is provided on the lower end surface of the insulating base 11. A telescopic column 13 is matched at the lower end of the insulating base 11, and the telescopic column 13 is connected to a drive motor 14, and the drive motor 14 and the telescopic column 13 are connected through a gear linkage. The drive motor 14 is controlled by a controller 15.

[0016] like Figure 1 As shown, the power controller 10 is connected to an external power source 1, and a power socket 2 is provided on the power controller 10, and the power socket 2 matches the power socket 3 of the water heater 0. A lower electrical contact panel 16 is provided on the upper end surface of the telescopic column 13, and a certain distance is between the upper electrical contact panel 12 and the lower electrical contact panel 16, and the upper electrical contact panel 12 matches the lower electrical contact panel 16, and one end of the upper electrical contact panel 12 is connected to the power socket 2, and one end of the lower electrical contact panel 16 is connected to the external power source 1. A transformer 17 is provided on the power controller 10, and a 24V voltage power supply is provided to the fluid mechanical control mechanism 20 by stepping down the voltage through the transformer 17.

[0017] like Figure 1 As shown, the fluid mechanical control mechanism 20 is designed with a water inlet interface 21 and a water outlet interface 22. The water inlet interface 21 is connected to the water outlet of the water heater 0, and the water outlet interface 21 is connected to the shower interface. The fluid mechanical control mechanism 20 is built with a mechanical opening and closing device 23 and a Hall sensor 24. The mechanical opening and closing device 23 is controlled by water flow. The mechanical opening and closing device 23 cooperates with the Hall sensor 24. The Hall sensor 24 is connected to the controller 15 through a signal transmitter and receiver 30.

[0018] like Figure 1 As shown, the mechanical opening and closing device 23 includes a force plate 25 and a magnetic gravity block 26. The force plate 25 is directly opposite to the water inlet interface 21. The magnetic gravity block 26 is arranged directly below the Hall sensor 24. The magnetic gravity block 26 matches the Hall sensor 24. A one-way check valve 27 is also provided at the lower end of the magnetic gravity block 26. The one-way check valve 27 is used to prevent the backflow of water from interfering with the movement of the magnetic gravity block 26.

[0019] like Figure 1 As shown, when the user opens the water valve of the water heater 0, the water flow flushes the force plate 25, causing the magnetic gravity block 26 to move upward, and the magnetic gravity block 26 triggers the Hall sensor 24. The Hall sensor 24 sends a signal to the controller 15. The controller 15 controls the drive motor 14 to start. The drive motor 14 retracts the telescopic column 13 through gear linkage, and the upper electric contact panel 12 and the lower electric contact panel 16 are separated. The circuit is disconnected, and the water heater 0 is safely used under the condition of power failure. When the valve is closed, that is, when no one uses the water heater, the magnetic gravity block 26 moves downward due to the action of gravity, and the Hall sensor 24 has no signal output. The power controller 10 defaults that the circuit is in a normally closed power-on state, and the water heater 0 heats normally, allowing the user to truly use the electric water heater safely in a power-off state, with the advantages of simple structure and safe use.
