In the technical schemes, a liquid level detection element can be arranged, so that the quantity of liquid in the container can be checked through the liquid level detection element when a product is heated, meanwhile, a controller can be connected with the liquid level detection element, so that the controller can control the electrifying condition of the heating element through the liquid level detected by the liquid level detection element, specifically, when the liquid level detection element detects that the liquid level in the container is low or the heating device is positioned on a desktop and is not inserted into the liquid, the controller cuts off the power of the heating element to ensure that the heating element can not be electrified to work, so that the heating element can be stopped from heating when the liquid in the container is insufficient, and the power of the heating element can be automatically cut off in time to avoid fire and the like when the heating element is not inserted into the container and is electrified by mistake, thereby reducing the potential safety hazard of the heating device, the use safety of the product is ensured. Meanwhile, it is preferable that a temperature detecting element, such as a thermistor or other type of temperature sensor, etc., be provided so that the temperature of the liquid in the heating device during heating can be detected by the temperature detecting element, and the temperature detecting element be connected to the controller so that the controller can control the operation of the heating body, such as controlling the energization of the heating body, or the amount of power, etc., according to the temperature detected by the temperature detecting element. Therefore, on one hand, the heating device can adaptively adjust the power, the working time, the heating process and the like of the heating body according to the temperature of the liquid during heating, and on the other hand, the heating device can stop heating when the temperature of the liquid is heated to a certain temperature, so that the temperature of the liquid can be reasonably controlled, and the heating device can heat the temperature of the liquid to the temperature required by a user.

The temperature detecting element may be disposed entirely within the first housing, or may be disposed partially within the first housing and partially outside the first housing.

The first preset temperature here may be a fixed value set in advance according to experience or habit, such as 95 ℃ or 100 ℃, or a value reset by the user according to actual needs when the user uses the device specifically. For example, when the water heater is used for boiling water, the first preset temperature can be set between 85 ℃ and 100 ℃, and when the water heater is used for heating milk and the like, the first preset temperature can be set between 40 ℃ and 70 ℃ to prevent the milk and the like from being heated too hot.

The liquid level requirement here may be embodied as the liquid in the container being able to submerge the liquid level detection element, or the liquid level detection element being able to be in contact with the liquid in the container, etc.

The liquid level detection element is a liquid level sensor, and the temperature detection element is a thermistor.

In these technical solutions, the liquid level can be detected by the liquid level sensor, and the specific temperature of the liquid can be detected by the thermistor, but of course, the temperature detecting element can also be other components capable of detecting the temperature of the liquid.
