What is an Automatic Soap Dispenser?
An automatic soap dispenser automatically dispenses a measured amount of soap or hand sanitizer when you place your hand within its range. When used with taps in public bathrooms, they serve the purpose of conservation of soap used and prevention of transmission of infectious diseases through touching. When people use it, they don’t have to touch it to set the amount of soap output. All they have to do is remove their hands when they are satisfied with the amount of soap in their hands, and the soap dispenser will stop dispensing, preventing leaks or dripping.
Guey-Chaun Shiau was the person who submitted the idea for the first automated dispenser for patent rights in 1989. The idea got patented under the name “Automatic Cleaning-liquid Dispensing Device” with a patent issued in 1991
How Auto Soap Dispensers are Applied?
In recent times, the application of automatic soap dispensers and faucets have increased exponentially. Public and private institutions have spent a good amount of money to have this touchless technology in their bathrooms.
The application of the automatic soap dispenser has now spread to hospitals, kindergartens, office buildings, schools, restaurants, home kitchen, bathroom, and other public places. (Click here to wholesale automatic soap dispensers from VOLI manufacturer)
The Working Principle of Automatic Soap Dispenser
Infrared Sensors – These sensors burst ultrasound or microwave energy and wait for it to respond, triggering soap dispensing. When this happened, your hands are placed around the dispenser at a distance no more than 3.35 inches or 8.5 cm.
If you remove your hand from the below the pump, the light reflection is absent, so there is no detection of a pulse. This causes the dispenser to stop working. The soap dispenser also has a passive infrared technology, which is activated when it detects energy coming from human body heat. This fluctuation causes the pump to work.
Photosensors are now more popular and accessible versions of the soap dispenser. They use a light sensor and a source of focused light to function. The pump mechanism is activated when your hands are placed under a beam of light. The photosensors and infrared sensors are almost indistinguishable, even though they work together sometimes when the source of light for the photosensor is a laser beam.
Air induction technology is patented by SimpleHuman soap dispenser producer. It works by creating a vacuum of micro-bubble infusion into the soap at high intensity. This technology allows for the easy control of the precise air – soap ration to create a balanced foam texture. The pumping mechanism uses this technology, which is powered by source or through the handle.
Some automatic dispensers have a feature where an LCD shows the volume of soap available in the dispenser, along with the volume level. These LCDs are protected against moisture, and they allow you to take a quick peek and evaluate what is still left in the dispenser and how it works.
Adjustment of the level of soap contained in the dispenser cannot be done because that would mean touching the dispenser, so this option is very important when you don’t have much soap left.

| The user’s hand is too far away from the sensor. | Place your hand closer to the sensor (about 64 mm) below the sensor. For best results, hold your hand flat. |
| Lighting conditions near the dispenser are not allowing the sensor to work properly. | Transfer the dispenser to a different location where there are no highly reflective surfaces and direct sunlight. |
| Attempted to trigger the sensor using a dark-colored dishcloth or sponge. | Activate the sensor using a light-colored dishcloth, sponge, or by hand. |
The Unit Makes Noise But Does Not Dispense Soap
| Possible Cause | Corrective Action |
| The unit needs priming. | Cycle the dispenser about eight times before you start with an empty tank. Also, do this if you haven’t used the unit for a long while. Also, try to trigger the sensor until the soap is dispensed. |
