[0001] The utility model relates to the technical field of water dispenser sensors, in particular to a water dispenser based on an open-loop Hall current sensor. Background Art

[0002] As an important part of modern smart home, smart water dispenser has been widely used in homes, offices, schools and other places. It not only has the functions of traditional water dispenser, but also integrates advanced intelligent technology to achieve a more convenient, safe and energy-saving drinking experience. In the internal structure of the smart water dispenser, the water pump plays a vital role.

[0003] At present, in order to implement water pump detection, an open-loop Hall current sensor is usually installed on the water pump. The sensor can monitor the working current of the water pump in real time to determine whether the working status of the water pump is normal.

Currently, the Hall current sensor is connected to the inside of the water dispenser by screws. However, although this installation method ensures the stability and reliability of the sensor during the operation of the water dispenser, it brings certain inconveniences and complexities when performing daily inspections or maintenance of the Hall current sensor. Since the sensor is tightly fixed inside the water dispenser, maintenance personnel need to spend more time and energy to disassemble and reinstall the sensor, which can easily cause damage to the sensor, which undoubtedly increases the difficulty and time cost of the inspection work.
