For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0027] As Figures 1 to 4 As shown in the figure, an intelligent induction liquid heater, comprising a heater body 1, which is provided with a heating disc 11 for placing a liquid container 2. The liquid container 2 is a glass container. Other conventional components in the heater body 1 have no direct relationship with the present application, and will not be described here.

[0028] The heater body 1 is elastically connected with a detection bracket 3, and the front surface of the detection bracket 3 is provided with a temperature sensor 31 and a water level sensor 32. The water level sensor 32 is a capacitive sensor, and the temperature sensor 31 is a thermistor. The liquid container 2 is placed on the heating disc 11 and presses the detection bracket 3 to detect the water level, and the temperature sensor 31 contacts the bottom of the liquid container 2 to detect the temperature. When the liquid container 2 is placed on the heating disc 11, the bottom of the liquid container 2 contacts and presses the detection bracket 3, at this time the temperature sensor 31 contacts the bottom of the liquid container 2, the temperature of the liquid container 2 can be detected, and temperature sensing is realized. Since the detection bracket 3 moves downward, at this time the water level sensor 32 also sends different signals, so as to detect whether the liquid container 2 is filled with water.

[0029] The heater body 1 includes a base 12 and a top cover 13, and the base 12 is provided with a control circuit board 14 connected with the water level sensor 32 and the temperature sensor 31 to obtain detection signals. Specifically, the detection bracket 3 is connected below the top cover 13, and the detection bracket 3 and the top cover 13 are connected by elastic members. The elastic members are springs 34, and the number of the springs 34 is at least one. Preferably, in order to ensure the balance of the movement of the bracket, the number of the springs 34 can be selected as three.

The planes 22 on both sides of the bottom platform 21 contact the boss structure 33 and press the boss structure 33 downward, so that the detection bracket 3 moves downward. The liquid container 2 contacts the temperature sensor 31 on the surface of the boss structure 33, so that the temperature sensor 31 can detect the temperature of the liquid container 2. Since the water level sensor 32 on the back surface of the boss structure 33 moves downward synchronously, the water level sensor 32 also sends detection signals, so that whether the liquid container 2 is filled with water can be detected.

[0031] Embodiment 2, as Figure 5As shown, the back of the detection bracket 3 is not provided with a capacitive sensor, but a micro switch is arranged at the lower part of the detection bracket 3, and the liquid container 2 is placed on the heating disc to make the detection bracket be pressed down, then the detection bracket is pressed down to touch the micro switch, thereby judging whether the liquid container 2 is on the heating disc or not.
