The working principle of infrared sensor soap dispenser

The advancement of science and technology freed people from heavy physical labor and used their talents to build everything. And gradually pursue the comfort of life on a higher level. Even for such a common thing as hand washing, we just rinse with water or put some soap on our hands, and now we are also pursuing how to be cleaner and hygienic.

Now some of the more high-end shopping malls and hotels equipped with hand dryers will also be equipped with infrared sensor soap dispensers, and a small number of households will also use the sensor soap dispenser.

Because the push-type soap dispenser needs to be pressed by the thumb to press the soap into the palm of the hand, sometimes the quality of the product is not enough to press and it will be quite difficult, and the amount of liquid is small.

The sensor soap dispenser uses the principle of a human body sensor. The sensor soap dispenser is equipped with a human body sensing device near the liquid outlet. When the sensor of the lens and the pyroelectric tube senses the signal announced by the human body, it will output and expand the electronic circuit to form a signal to open the switch and drive The internal DC motor rotates to push the switch piston to squeeze out the soap. The touch between the human body and the machine is completely avoided.
