Abstract: A pull type rotary massage nozzle sequentially includes a nozzle holder, a nozzle core seat, a nozzle surface cover, and a nozzle core assembly. The nozzle core seat is detachably mounted on the nozzle holder. The nozzle surface cover is fixedly mounted on the nozzle core seat. The nozzle core assembly is mounted in the nozzle core seat and may circumferentially rotate about a mounting axle relative to the nozzle core seat and the nozzle surface cover, and may also axially float or sink along the mounting axle relative to the nozzle core seat and nozzle surface cover. The nozzle surface cover is provided with a static torsion rib. The nozzle core assembly is provided with a dynamic torsion rib. The dynamic torsion rib is selectively engaged with or separated from the static torsion rib along with floating or sinking of the nozzle core assembly.

Abstract: A control method for a lamp system based on RGB wiring arrangement includes outputting a first PWM signal through a connecting line and a second PWM signal through another connecting line; wherein, the first PWM signal is used for controlling an on/off time interval of a first switch device on the connecting line to generate a continuous variable level at two terminals of the resistor on the connecting line, the continuous variable level forms a digital signal, and the second PWM signal is used for controlling the second switch device on the another connecting line to be normally-off to provide a stable power supply; the lamps acquiring corresponding control information from the digital signal through ID matching; and after the control information is decoded by the decoding module, currents transmitted to the coloured light emitting modules being regulated to control the coloured light emitting modules.

Abstract: The invention provides a lighting fixture based on a DMX controller, and a control method. The lighting fixture includes an NFC address writer, a DMX controller for outputting light control data, NFC controllers receiving data from the DMX controller, and DMX lamps receiving data from the NFC controllers, wherein the DMX controller, the NFC controllers and the DMX lamps are electrically connected in sequence, the NFC address writer is used for modifying address information of the NFC controllers in real time, the NFC controllers selectively extract the light control data output by the DMX controller according to the address information and output the extracted light control data to the DMX lamps, and the DMX lamps change light according to the light control data received from the NFC controllers.

Abstract: A massage nozzle includes a nozzle housing and a nozzle core detachably attached in the nozzle housing. The nozzle housing is split-type and includes a cover mounted in a hole of a wall of a hot tub, a nozzle seat and a fastener. The cover includes an end ring and a side wall extending from the end ring. The side wall is conformed with the hole. The nozzle seat includes an inlet and a spray end which has a surface conformed with the side wall. The nozzle seat passes through and detachably connects with the cover. The outer circumferential surface of the spray end contacts with an inner surface of the side wall. The fastener is detachably sleeved on the outer circumferential surface of the nozzle seat and cooperates with the cover to fix the nozzle seat to the hot tub. The installation is convenient and the cost is reduced.

Abstract: 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.
