The Hall switch is arranged on the bracket 200 and can detect the proximity of the magnet. Specifically, the Hall switch is an active electromagnetic conversion device made by integrated packaging and assembly technology based on the principle of the Hall effect. The Hall switch can sense the magnitude of the magnetic flux. When the magnetic flux reaches a preset value, When the value is set, the internal trigger of the Hall switch flips, and the output level state of the Hall switch also flips accordingly, so that the magnetic input signal can be converted into an electrical signal. The magnet in the float box will move up and down with the liquid level, and the magnetic flux detected by the Hall switch will also change accordingly. When the Hall switch is in the connected state, the controller receives the signal and determines that the kettle 100 has been placed on the bracket 200. If the liquid level in the kettle 100 does not reach the preset level, the magnet is far away from the Hall switch, and the magnetic flux sensed by the Hall switch cannot make the trigger inside the Hall switch flip, the controller will control the water valve. Turn on and fill the kettle 100 with water. During the water filling process, the liquid level will rise to drive the float box 122 to move upward, and the magnet will also approach the Hall switch until the liquid level in the kettle 100 reaches the preset level, and the magnetic flux sensed by the Hall switch also reaches the preset level. Value, the trigger inside the Hall switch flips to switch the output level state of the Hall switch, and the controller will control the water valve to close and stop water injection. Therefore, the Hall switch determines the liquid level in the kettle by detecting the position of the magnet, and the controller can control the opening and closing of the water valve according to the detection signal sent by the Hall switch, so as to automatically fill the kettle with water when needed.

As shown in FIGS. 4-5, the water injection port 110 is arranged on the lid 120.
