| How does an automatic soap dispenser work?

Automatic soap dispenser, also known as soap dispenser and induction soap dispenser, is a machine that can automatically dispense soap through induction. The switch, thus working to spray soap or foam, is very practical.

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

In fact, the working principle of the automatic soap dispenser mainly uses the principle of infrared induction, the inner device of the automatic soap dispenser, the deceleration mechanism and the piston and other devices. Among them, the sensor has a lens and a pyroelectric tube. When it can receive the given position of the soap liquid, the sensor will sense the change of the infrared rays of the human body and generate a signal. This signal is amplified by the electronic circuit to generate a switch signal. The switch signal drives the DC motor to drive the deceleration mechanism to rotate. The connecting rod of the mechanism pushes the piston and squeezes out the soapy liquid.

Most automatic soap dispensers work in the form of setting timed supply of soap or foam, that is to say, automatic soap dispensers generally sense only one liquid at a time, and the liquid discharge time is limited, and automatically when the set time is reached. Stop the operation of the machine, which is mainly to prevent waste.
