In fact, the working principle of the touchless soap dispenser mainly uses the principle of infrared induction. The touchless soap dispenser has built-in sensors, deceleration mechanisms and pistons and other devices. Among them, the sensor has a lens and a pyroelectric tube. When the position of the soap liquid is given, the sensor will sense the change of the infrared rays of the human body 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 deceleration mechanism to rotate. The connecting rod pushes the piston, squeezing out the soapy liquid.
Most touchless soap dispensers work by setting a timed supply of soap or foam, that is, touchless soap dispensers generally sense only one liquid at a time, and the liquid time is limited, and the machine will automatically stop when the set time is reached. operation, which is mainly to prevent waste.
