The AC toilet squat pit sensor does not respond, and the light does not turn on, what is the fault?

Sensor repairs can be more expensive than buying a new one. Generally, the circuits are sealed and not easy to repair.

This kind of electrical appliances that are often touched by the human body are generally DC or safety voltage (36V or less), and strong electricity is never allowed.

Under normal circumstances, any flush toilet, 4-5 years of use will be fouled, the original smooth ceramic surface of the fouling, it seriously affects the drainage capacity of the toilet, resulting in the inability to flush in time, slow drainage, which is usually caused in the process of use, generally the only longer way to appear this phenomenon is to replace the toilet, even if it is descaled in various ways, the siphon elbow inside the toilet can not be completely removed, there is a temporary improvement, and this phenomenon will still appear after a while. >>>More

The toilet infrared sensor is realized by connecting the solenoid valve through the infrared sensor switch. >>>More

This is done through the principle of infrared reflection When the human hand or a certain part of the body is in the infrared region, the infrared rays emitted by the infrared emitting tube are reflected to the infrared receiving tube due to the blocking of the human hand or body, and are sent to the pulse solenoid valve through the signal processed by the microcomputer in the integrated circuit; >>>More
