A wall mounted soap dispenser typically works by using an infrared sensor to detect hand motion, triggering a mechanism that dispenses a pre-measured amount of soap.
Here's a breakdown of the process:
- Hand Detection: The dispenser is equipped with an infrared (IR) sensor. This sensor emits an infrared beam.
- Activation: When you place your hand under the dispenser's spout, your hand breaks the infrared beam. The sensor detects this change.
- Signal Transmission: The sensor sends a signal to the dispenser's internal control system.
- Dispensing Mechanism: The control system activates a pump or valve. This mechanism is designed to dispense a specific amount of liquid soap or foam.
- Soap Delivery: The pump or valve draws soap from a reservoir within the dispenser and releases it through the spout and onto your hands.
- Reset: Once the soap is dispensed, the mechanism resets, ready for the next activation.
The key components that make this happen are:
- Infrared Sensor: Detects the presence of hands.
- Control System (Circuit Board): Processes the signal from the sensor and activates the dispensing mechanism.
- Pump or Valve: Dispenses the soap. This can be a peristaltic pump, a piston pump, or a solenoid valve.
- Soap Reservoir: Holds the liquid soap.
- Power Source: Typically batteries or a wired electrical connection.
The advantage of these dispensers lies in their touch-free operation, promoting hygiene and reducing the spread of germs. The pre-measured dispensing also helps to conserve soap and reduce waste.
