[0084] The detection method and principle of the water quality detector 1 will be described below.

[0085] First, the water sample to be detected is placed in the storage cavity 1211 of the storage barrel 121. For example, the water sample to be detected can be injected into the storage cavity 1211 of the storage barrel 121 by using a syringe. Preferably, in the embodiment of the present application, since the water quality detector 1 has good sealing performance, the water quality detector 1 can be directly placed in the water sample to be detected for sampling, thereby saving the cumbersome sampling steps and facilitating convenient and fast operation.

[0086] Then, the user controls the shell button 114 to control the opening and closing of the irradiation light source 41 and the photoelectric receiver 42. In the storage cavity 1211 of the storage barrel 121, the detection tablet reacts with the measured substance in the water sample to be detected, so that the water sample to be detected presents different colors. Then, the water sample to be detected is irradiated by the super-high-brightness white light LED light source, and the wavelength of light is accurately measured by the high-performance photoelectric receiving device. After analysis and processing by the built-in program, accurate detection results can be quickly given, avoiding the error of naked eye observation and ensuring the accuracy and consistency of the test results. In other words, when the LED light source irradiates the water sample, specific light will be absorbed by the water sample, and the degree of absorption is related to the color of the liquid, so that after the irradiation light source 41 irradiates the water sample to be detected, the photoelectric receiver 42 quickly obtains accurate detection results according to the RGB value of the water sample to be detected combined with the preset program algorithm.

[0087] In conclusion, the water quality detector 1 has good sealing performance, facilitates sampling of the water sample to be detected, and avoids damage caused by the water sample to be detected entering the water quality detector 1, so that the water quality detector 1 can be directly placed in the water sample to be detected for sampling, thereby saving a complicated sampling step and facilitating convenient and fast operation. In addition, the water quality detector 1 irradiates the water sample through the irradiation light source 41, then accurately measures the light wavelength and detects the color change of the water sample through the photoelectric receiver 42, thereby avoiding errors in visual observation and ensuring the accuracy and consistency of the test results.
