AI Technical Summary

Technical Problem

Existing detergent concentration detection methods in washing equipment suffer from inaccurate detection, high equipment costs, complex processing, and are not applicable to scenarios where detergent dosage is gradually increased, thus failing to achieve ideal washing results.

Method used

A detection method comprising a hydrophobic aggregation-induced emission (AIE) fluorescent probe composition is employed to detect the critical micelle concentration of washing water in a washing device. A non-volatile organic solvent is used as an auxiliary agent, combined with a fluorescent sensor, to achieve simple and rapid concentration detection and control.

Benefits of technology

It improves the accuracy of detergent dosing, reduces equipment costs, simplifies the process, and enables efficient detection of the critical micelle concentration of detergent in the washing water within the washing equipment, achieving optimal cleaning efficiency.

Abstract

The present application discloses a washing equipment, a detergent dispensing control method and system, which collects a predetermined amount of washing water as a sample from a sink; adds a predetermined amount of probe solution to the sample, the probe solution comprising a fluorescent probe composition comprising a probe and an auxiliary agent, the probe being an aggregation-induced emission (AIE) molecule; detects the detergent concentration of the sample added with the probe solution and outputs a detection signal; determines whether the detected detergent concentration reaches a critical micelle concentration (cmc), and based on the determination result, controls the subsequent dispensing of the detergent. The present application determines that the cmc in the washing water is the best point for washing and decontamination efficiency or the highest point for cost performance. When a hydrophobic AIE molecule is used, a non-volatile auxiliary agent is used. A low-sensitivity detection device with a specific detection wavelength is used, which eliminates the interference of fluorescent whitening agents and realizes simple, fast and efficient detection and determination of the cmc of the washing water in the washing equipment application scenario.
