Example Embodiment

[0020] The present invention will be further described below in conjunction with the drawings and embodiments.

[0021] As attached figure 1 As shown, the present invention provides an internal water-filling kettle, including a kettle body 1, a kettle lid 2, a spout 3, and a kettle handle 4 are arranged on the kettle body 1, and a heating plate 5 is arranged in the kettle body 1. An electric heating chassis 6 is arranged below the kettle body 1, a water filling bucket 10 is arranged below the electric heating chassis 6, and a water pipe 11 is arranged inside the water filling bucket 10, and the water pipe 11 penetrates into the electric heating chassis 6, on the electric heating chassis 6 A water outlet 8 is provided, and a water receiving port 7 is provided under the kettle body 1, and the positions of the water outlet 8 and the water receiving port 7 correspond to each other;

[0022] The electric heating bottom plate 6 is provided with a water pump, the water pump is connected to a water pipe 11, a built-in water pipe is arranged inside the pot handle 4, the built-in water pipe is connected to the water pipe 11, and a backflow prevention device 12 is provided on the built-in water pipe to avoid water in the pot. From the pot handle 4, a pressure sensor 9 is installed at the water receiving port 7 of the pot body 1, a water level sensor 13 is installed at the highest limit water injection position in the pot body 1, and the water level sensor 13 sends a high-frequency circuit signal for feedback A control chip is given to control the turning off of the water pump, and the inside of the electric heating chassis 6 is provided with a control chip that receives signals from the water level sensor 13 and the pressure sensor 9 and controls the turning on of the water pump.

[0023] The backflow prevention device 12 adopts a one-way valve, the built-in water pipe adopts a food-grade silicone hose, the electric heating chassis 6 and the bottom of the pot body 1 are provided with a positioning device that prevents the pot body from rotating arbitrarily, and the positioning device may be an electric heating chassis 6. With the interlocking slot provided on the kettle body 1.

[0024] In the internal water-filling kettle provided by the present invention, a water pump is arranged on an electric heating chassis 6, and a pressure sensor 9 and a control chip are arranged in the electric heating chassis 6. When the kettle body 1 is placed on the electric heating chassis 6, the pressure sensor 9 transmits high-frequency circuit signals To the control chip, the control chip controls the water pump to turn on and inject water into the kettle body 1, and the water flows into the kettle body 1 through the water pipe 11 and the built-in water pipe. When the water in the kettle body 1 reaches the highest limit water injection position, the water level sensor 13 sends out a high frequency circuit The signal is fed back to the control chip to control the shutdown of the water pump; in addition, by setting the value of the pressure sensor 9, when the pot body 1 is placed on the electric heating chassis 6 and the water level reaches the highest limit position, the pressure of the electric heating chassis 6 reaches the set value, The pressure sensor 9 sends a high-frequency circuit signal to feedback to the control chip to control the water pump to shut down.

[0025] As attached figure 2 As shown, the control system of the internal water injection kettle provided by the present invention is controlled by the control chip to control the pressure sensor 9, the water level sensor 13, and the water pump. In addition, the internal water injection kettle is also provided with a control panel and touch switches, which are operated through the control panel The functions of adding water, boiling water, and keeping warm, and the circuit connection between the control panel and the control chip are in the prior art, and a variety of existing technologies can be implemented, so it will not be repeated.

[0026] The present invention provides an internal water-filling kettle to control the water level:

[0027] 1. Water pump flow control, mostly by controlling the working time of the water pump to control the water volume;

[0028] 2. The water level sensor 13 is set at the highest position in the kettle body 1. When the water level reaches this position, the water level sensor 13 sends a high-frequency circuit signal to feed back to the electric heating chassis 6 control chip to control the water pump to shut down;

[0029] 3. The backflow prevention device 12, such as a one-way valve, prevents the water from flowing back from the pot handle 4 to the bottom of the pot body 1 from causing a circuit short circuit;

[0030] 4. The electric heating chassis 6 is equipped with a pressure sensor 9. When the kettle body 1 is placed on the electric heating chassis 6, the water pump can work. When the water pump is removed, the water pump stops working, the water is full or the kettle body 1 is removed to prevent the water from being filled and overflowed.

[0031] Although the present invention has been disclosed as above in preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the present invention The scope of protection shall be as defined in the claims.
