Abstract: An anti-siphon device for a flush valve having an air-inlet sealing diaphragm, a diaphragm bracket with an air inlet, a flex sleeve, a venting bracket, and an offsetting spring. The deformation power of the air-inlet sealing diaphragm is comparatively small. When compared with existing anti-siphon reflux devices, this anti-siphon device has a very low current pressure loss and can prevent leaking. When the anti-siphon device is applied in heating and plumbing devices, such as a flush valve, the current pressure can be retained and thus satisfactory flush effect is achieved.

Abstract: An active infrared induction instrument powered by a dry battery capable of reducing power consumption through the adjustment of the emitter pulse width. The infrared emitted LED emits infrared signals, which, after being reflected by an object, are received by the infrared photodiode. The infrared signals received the infrared signals received by the infrared photodiode then enter an integrated circuit chip through a comparator. The pulse widths of the infrared emission pulse signals are dynamically adjusted after the width of the pulse series is received by the discrimination chip, thus reducing the emission power consumption to save energy.

Abstract: An application solution using infrared communication in automatic sensing for use in bathroom sanitary wares. A main circuit board emits an infrared pulse signal on one side to detect a user. After a user is detected, the main circuit board produces a group of pulse collated code opening valve signals to drive another infrared emitting diode to send this collated code. The infrared receiving diode on the slave board receives this collated code, transforms it into a pulse signal and then transmits it to the chip for procession. If the collated codes agree with each other, the solenoid valve can be controlled to open or close the valve. At the same time, the collated code is returned to the main circuit board, which consequently stops emitting the collated code signal for opening the valve.

Abstract: An automatic sensing system used in automatic sensing sanitary wares. The main circuit board uses infrared signal on one side to detect a user, and then sends the user-detected or no-user signal through radio control to the slave circuit board inside the toilet water box. After the slave circuit board receives the radio control signal from the main circuit board, it switches on or off the solenoid valve to control flushing of the water box.
