This is one of the water boilers commonly found in the prior art.

There are also water boilers provided with two or more temperature sensors in the prior art, for example, patent document with application number 201220629130.8 discloses a water boiler controlled by two temperature sensors, which comprises a housing, a water tank is arranged in the housing, a water outlet valve and a water inlet pipe communicated with the water tank are respectively arranged at the front end and the rear end of the water tank, a heating pipe is arranged in the water tank, a control panel is arranged on the housing, an upper temperature sensor and a lower temperature sensor are arranged in the water tank, the upper temperature sensor and the lower temperature sensor are positioned at different heights of the water tank, and whether the water tank is heated or not is controlled jointly by the upper temperature sensor and the lower temperature sensor.

For example, the patent document with the application number of 201920515467.8 discloses a commercial water boiler, which comprises a boiler body, a water inlet, a water outlet valve and a water receiving disc, wherein an electromagnetic heating plate is arranged in the water boiler, a snakelike heating pipe is fixed on one surface of the electromagnetic heating plate, an electromagnetic heating wire coil is fixed on the other surface of the electromagnetic heating plate, a flowmeter and a first temperature sensor are arranged at the inlet of the snakelike heating pipe, a second temperature sensor is arranged at the outlet of the snakelike heating pipe, the heating power of the electromagnetic heating wire coil can be controlled according to the temperature set by a controller, the water outlet temperature is more accurate, and the electric energy utilization rate is high.

However, the water boiler is generally used for business, the capacity of the water boiler is large, the water tank is used for storing water, and the water tank adopts a mode of entering from the bottom to the top, so that the temperature of one cup of water received by a user is the temperature of the water at the upper part of the water tank, but not the temperature of the water at the lower part of the water tank or the average temperature in the water tank, and therefore, the water boiler in the prior art cannot provide more accurate temperature of drinking water for the user.
