AI Technical Summary

Technical Problem

Existing water dispensers lack sufficient water level monitoring accuracy, and the sensors are easily affected by water quality, making it impossible to achieve dynamic gradient monitoring. This poses a risk of overflow or dry burning, and there is a lack of a visual water level interaction interface.

Method used

By employing infrared liquid level sensing components combined with high and low water level sensors and through the position design of overflow pipes and water supply pipes, real-time and accurate monitoring of water level changes can be achieved. The integrated control system supports signal processing and display screen interaction, forming a dual monitoring mechanism.

Benefits of technology

It enables real-time and accurate monitoring of water levels, avoids the risks of overflow and dry burning, improves the stability and safety of equipment operation, and enhances user interactivity.

Abstract

A water conveying pipe and an overflow pipe are arranged at the top of an ice water box body, an infrared liquid level sensing assembly is arranged in a communicating vessel, and the infrared liquid level sensing assembly comprises a high water level sensor close to the top of the box body and a low water level sensor close to the bottom of the box body. Through the infrared liquid level sensing assembly arranged in the communicating vessel, the dynamic change of the water level is tracked in real time by utilizing double monitoring of a high water level sensor and a low water level sensor, and an active anti-overflow protection mechanism is formed by combining the hierarchical layout of the overflow pipe and the water conveying pipe. The high-water-level sensor can trigger the water delivery pipe to close or give an alarm when the liquid level is close to the upper limit, and equipment is prevented from being damaged by overflow and permeation; the low-water-level sensor can detect insufficient water in time. The infrared sensing technology overcomes the defect that traditional mechanical detection is prone to being affected by water scale and condensation in a non-contact mode, and detection precision and long-term stability are ensured. The display screen synchronously feeds back the water level state, real-time control of a user on the equipment is enhanced, and safety and operation intuition are both considered.
