Working Principle: It is equipped with built-in sensors, a reduction mechanism, a piston, and other components. The sensor is fitted with a lens and a pyroelectric tube. When it detects a hand approaching, it senses changes in the infrared rays emitted by the human body and generates a signal. After the signal is amplified and compared by an electronic circuit, a switch signal is produced, which drives a DC motor to rotate the reduction mechanism. The piston is then pushed via a connecting rod to dispense the soap liquid.

Product Features:

• Hygienic and Convenient: No manual pressing is required. Simply extend your hand near the liquid outlet, and the liquid will be dispensed automatically. This avoids direct contact between hands and the soap dispenser, effectively preventing cross-infection and ensuring better hygiene. It is particularly suitable for households with the elderly or children.
• Precise Liquid Dispensing: Usually controlled by a microcomputer, it enables intelligent automatic liquid dispensing with a relatively fixed amount each time, effectively controlling soap usage and avoiding waste. Some products also support adjustable liquid output, allowing users to set it according to actual needs.
• Wide Applicability: In addition to common hand sanitizers, it can be used with various viscous liquids such as dishwashing liquid, disinfectant, and shower gel. Simply pour the liquid directly into the soap dispenser or dilute it as required before pouring.
• Compact Design: As a desktop device, it is generally small in size, occupying little space, and can be flexibly placed on washbasins in bathrooms, kitchens, etc. It comes in diverse designs—some are simple and stylish, others are cute and exquisite—adding a decorative touch to the space.
