Patent number: 11662040Abstract: The present disclosure provides an electric water diverter, which includes a controller, a brushless DC motor, a core and a T-shaped body. The controller is electrically connected to a fixed Hall PCB circuit board and the brushless DC motor in turn. The brushless DC motor has a rotating shaft detachably connected to the core via a connector, which is also embedded with a magnet cooperating with the Hall PCB circuit board. The Hall PCB circuit board obtains a relative position signal of the rotating shaft through Hall induction and feeds the relative position signal back to the controller. A user controls the brushless DC motor to perform phase rotation through the controller and drive the connector and the core to selectively rotate forward or backward relative to the T-shaped body. Thereby, stepless adjustment of water flow from water outlet is achieved.Type: GrantFiled: May 5, 2022Date of Patent: May 30, 2023Assignee: Guangzhou Rising Dragon Recreation Industrial Co., Ltd.Inventors: Xuewen Liu, Ziqin Guo, Yingjun Wu, Huamin Tang
