Abstract: The present application relates to a communication system for a bathroom product such as a toilet. The communication system includes a remote control device and a host device that directly controls the bathroom product. The remote control device includes an infrared module, a first RF communication module, and a first microcontroller connected to the infrared module and the first RF communication module. The host device includes a second RF communication module and a host microcontroller. The first microcontroller uses the infrared module to detect whether a person has entered the proximity of the remote control device. The first microcontroller is configured to cause the first RF communication module to activate, from a deactivated state, in response to the infrared module and the first microcontroller detecting that a person has entered the proximity of the remote control device.

Abstract: The present invention application provides a bathtub. On the bathtub wall are fixed ultrasonic transmitters, and an ultrasonic transducer drive circuit is electrically connected to ultrasonic transducers. The ultrasonic transmitters further include an ultrasonic divergent structure which, after reflecting and scattering the ultrasonic waves emitted by the ultrasonic transducers, transmits the same into the bathtub (e.g., into the water of the tub).

Abstract: An overload protection driving mechanism is provided. The driving mechanism includes a first driving assembly having a mounting part, a second driving assembly having a friction part, and a locking assembly for slipably locking the first driving assembly and the second driving assembly. The locking assembly includes a friction surface matching an inner ring surface of the friction part and a mounting hole matching the mounting part.

Abstract: The present application relates to a foaming soap dispenser. The soap dispenser includes a housing, a liquid storage tank, a pump, a main control assembly and an output assembly. The arrangement of the pump allows for control of the output which prevents the air-liquid mixture from freely back flowing or dripping. The soap dispenser includes a controller configured to reverse the fluid pumping direction of the pump allowing for some liquid provided to the outlet to be returned to the liquid storage tank. Return of some liquid to the liquid storage tank prevents contamination.

Abstract: A bidet wand includes an arm and a nozzle. The arm includes one or more members, one or more connection tubes, and one or more inlet hoses. The one or more members are arranged in sequence from a first side to a second side and coupled to each other, the one or more members forming insertion portion at the first side. Each connection tube is coupled to and extends through the one or more members from the first side to the second side. Each inlet hose is coupled to one of the connection tubes at the second side and is configured to transfer water from a water source. The nozzle is configured to receive the insertion portion of the one or more members therein. The nozzle and the insertion portion include positive coupling features that are cooperatively configured to engage each other to couple the nozzle to the arm.

Abstract: The invention provides a drive assembly for a telescoping wand of water jet device. The drive assembly includes an internally engaged rotary disk. With rotation of the internally engaged rotary disk, the telescoping wand of the water jet device is caused to retract or expand.

Abstract: The present invention provides a bistable pulse solenoid valve control system and method. The control system includes a bistable pulse solenoid valve having a coil current, and including a coil frame, a coil having a magnetic flux, at least two permanent magnets, a valve core disposed inside the coil frame, and a frame configured to encapsulate the permanent magnets, the coil, the valve core, and the coil frame. The system also includes a main control circuit, a polarity conversion control circuit, and a drive current sampling detection circuit. The main control circuit is configured to generate a control signal and the polarity conversion control circuit is configured to control the direction and power on-off time of the coil current.

Abstract: A bidet wand for a toilet includes a nozzle, one or more inlet hoses, and a connector assembly configured to fluidly couple the nozzle to the one or more inlet hoses. The connector assembly includes one or more connector tubes, and first, second, and third members. Each connector tube is associated with one of the inlet hoses. The first, second, and third members are coupled to each other in axial alignment with each connector tube extending through the first member and the second member. Each inlet hose extends at least partially through the third member and is coupled to an inlet end of one of the connector tubes. The nozzle is configured to receive an outlet of each connector tube and at least a portion of the connector assembly therein.

Abstract: A liquid supply apparatus (e.g., for dispensing soap, shampoo, etc.) includes a liquid storage tank and a pump module connected to the storage tank. The liquid supply apparatus further includes a suck-back module. The suck-back module includes a chamber formed by a piston cover disposed at an end of a cylinder, a piston rod having a first end disposed in the chamber and a second end configured to extend through an opening in the piston cover, and a plug disposed in the chamber and connected to the first end of the piston rod.

Abstract: A touch sensing device for a kitchen or bath appliance includes a control panel. A sensing guide and a plurality of sensing function keys are provided on the control panel. The sensing guide and the plurality of sensing function keys operate via capacitive touch sensing.
