Contamination detection device, automatic cleaning device, contamination detection and auto-cleaning equipment and method using the same

An automatic cleaning device for cleaning a sample container, comprising:

• an ultrasonic generation unit configured to generate an oscillation with an ultrasonic frequency;
• a hollow sleeve;
• an ultrasonic conduction rod connected to the ultrasonic generation unit, located in the hollow sleeve, and configured to conduct the oscillation to a test liquid that is to be measured within the sample container;
• and
• a cleaning brush component disposed on the hollow sleeve and configured to clean an inner wall of the sample container.

A contamination detection and auto-cleaning equipment, comprising:

• a contamination detection device for detecting a cleanliness of a sample container, comprising:
• a light emitter located at a light incident side of the sample container, and configured to emit an emission light, wherein the emission light becomes a detection light after traveling through the sample container;
• a detection-light receiver located at a position opposite to the light emitter, the position is at an light output side of the sample container, and configured to receive the detection light to obtain a detection-light intensity;
• and
• a controller coupled to the light emitter and the detection-light receiver and configured to obtain a cleanliness of the sample container according to a variation of the detection-light intensity;
• an automatic cleaning device for cleaning the sample container, comprising:
• an ultrasonic generation unit located at a configured to generate an oscillation with an ultrasonic frequency;
• a hollow sleeve;
• an ultrasonic conduction rod connected to the ultrasonic generation unit, located in the hollow sleeve, and configured to conduct the oscillation to a test liquid that is to be measured within the sample container;
• and
• a cleaning brush component disposed on the hollow sleeve and configured to clean an inner wall of the sample container;
• and
• the controller coupled to the light emitter, the detection-light receiver and the automatic cleaning device, and configured to:
• control the light emitter to emit the emission light;
• obtain the cleanliness of the sample container according to the variation of the detection-light intensity;
• and
• when the cleanliness is lower than a predetermined value, control the automatic cleaning device to clean the sample container.
