What is the working principle of the automatic soap dispenser? What are the characteristics of the soap dispenser

1、 What is the automatic soap dispenser

The automatic soap dispenser, also known as soap dispenser and sensing soap dispenser, is a kind of machine that can automatically dispense soap by sensing. When you use it, extend your hand, and the sensing head of the automatic soap dispenser will sense the signal, turn on the switch of the soap dispenser, and spray soap or foam. It is very practical,

2、 What is the working principle of automatic soap dispenser

Many friends are very interested in the principle of soap dispenser. How does it automatically discharge liquid?

In fact, the working principle of the automatic soap dispenser is mainly based on the infrared induction principle. The automatic soap dispenser is equipped with sensors, deceleration mechanisms, pistons and other devices. Among them, the sensors are equipped with lenses and pyroelectric tubes. When the sensor senses that the human hand is at the position where it can receive the given soap solution, the sensor will sense the changes of the human body's infrared and generate a signal. This signal is amplified and compared by the electronic circuit to generate a switch signal, The switch signal drives the DC motor to drive the reducer to rotate, and the piston is pushed through the connecting rod of the reducer to extrude the soap liquid.

Most of the automatic soap dispensers work by setting the time to supply soap or foam. That is to say, the automatic soap dispensers generally sense that only one liquid is delivered at a time, and the delivery time is limited. When the set time comes, the machine will stop automatically, which is mainly to prevent waste.
