Modularized induction flushing device for a urinal
A recently filed patent (Publication Number: US20230313515A1) describes a modularized induction flushing device for a urinal. The device includes a water inlet and outlet assembly, a water drainage assembly, an electromagnetic valve assembly, and a power supply assembly. The device also features an induction module that can be switched between at least two induction modes, and the electromagnetic valve assembly responds to these different modes to control the flushing of the urinal.
The induction module of the device can include various types of induction assemblies, such as an infrared induction assembly, a conductance induction assembly, and a capacitive induction assembly. The water inlet and outlet assembly consists of a water inlet pipe connected to the electromagnetic valve assembly, a water outlet pipe, and a flushing nozzle that can be attached to the water outlet pipe. The flushing nozzle is designed to be placed on the upper portion of the urinal and has a flushing opening.
In one embodiment, the induction module includes an infrared induction assembly with an infrared induction controller and probe. The probe is attached to the water inlet and outlet assembly, specifically to the flushing nozzle, which has a slot allowing the probe to be exposed. Another embodiment includes a conductance induction assembly with a conductance inductor attached to the inner wall of the urinal, adjacent to the water drainage assembly. The conductance inductor is not in contact with the liquid in the urinal.
The device also includes a capacitive induction assembly with a capacitive inductor and electrodes. The capacitive inductor is removably bonded to the water drainage assembly, and the electrodes are attached to the outer wall of the water inlet port. The electrodes are not in contact with the liquid in the urinal and are arranged in sequence along the water drainage direction.
The modularized induction flushing device can be mounted on a wall, and the water drainage assembly connects to a sewage pipeline via a mounting plate. The electromagnetic valve assembly, power supply assembly, and induction module can be fixed to the inner wall of the urinal through a bracket or to the mounting plate through a connecting frame.
The patent also describes an induction urinal that incorporates the modularized induction flushing device. The induction module of the device can be attached to the water inlet and outlet assembly and/or the water drainage assembly in a replaceable manner, allowing for the switching of at least two induction modes.
In summary, the patent describes a modularized induction flushing device for urinals that allows for different induction modes and provides flexibility in installation and operation.
