The induction trigger mechanism of the automatic soap dispenser is one of its key technologies. Its purpose is to realize contactless and automated soap dispensing by sensing the position and presence of the user's hands.

sensor type

Automatic soap dispensers mainly use two mainstream sensing technologies, namely infrared sensing and ultrasonic sensing.

Infrared sensing: The infrared sensor emits an infrared beam. When an object enters the sensing range, the beam is reflected by the object and returns to the sensor, thereby triggering the dispenser to work.

Ultrasonic sensing: Ultrasonic sensors determine the distance and position of objects by emitting ultrasonic pulses and measuring their return time. When the user's hand enters the sensing range, the ultrasonic sensor will detect the reflected wave, triggering the operation of the soap dispenser.

Sensing range and sensitivity

Sensing range and sensitivity are important factors to consider when designing an automatic soap dispenser. Reasonable sensing range and sensitivity can ensure that users can easily trigger the dispenser under normal use without false triggering or missed triggering. The precise sensing range design prevents the dispenser from being activated without the user reaching out, improving device reliability and user experience.

Response time

The response time of an automatic soap dispenser is also an important consideration. Reasonable response time can ensure that the soap liquid is quickly released when the user reaches out, providing a smooth use experience. Often, this requires a balance between hardware design and software control to ensure fast and accurate response.

Energy management

In order to increase the service life of automatic soap dispensers, energy consumption management is an aspect that cannot be ignored. Sensors should be designed to consume as little power as possible to extend battery life or reduce dependence on external power sources. This may involve the sensor entering a low-power state when inactive, as well as a sensible wake-up mechanism that only activates the sensor when needed.

Immunity to interference

Considering the complexity of the use environment, the induction triggering mechanism of the automatic soap dispenser needs to have a certain degree of anti-interference. This includes a certain degree of resistance to the effects of light, temperature and other electronic devices to ensure stable and reliable operation in a variety of environments.

safety

Safety is a key aspect in the design of induction trigger mechanisms. Devices need to be able to accurately distinguish between the user's hands and other objects to prevent false triggering, especially in high-traffic public spaces. This can be achieved by introducing advanced algorithms and sensor fusion technology.
