Microfluidic detection system for refrigerator, control method of microfluidic detection system and refrigerator

Abstract

The invention relates to a micro-fluidic detection system for a refrigerator, a control method of the micro-fluidic detection system and the refrigerator. The microfluidic detection system comprises a microfluidic biochip and a detection cell formed in the microfluidic biochip, the microfluidic biochip is provided with a sample inlet, a communication port and a buffer solution inlet, and the sample inlet, the detection cell and the communication port are sequentially communicated through a micro-channel to form a main channel; a sample liquid in contact with the sample inlet is allowed to flow into the detection cell through the sample inlet and the micro-channel in sequence, and the buffer liquid inlet is communicated with the micro-channel connected between the communication port and the detection cell; the detection mechanism is used for detecting the detection pool to obtain preset detection parameters of the sample liquid; the buffer solution driving device is communicated with the buffer solution inlet and is used for promoting the buffer solution to flow into the main channel through the buffer solution inlet and flow out through the sample inlet, so that the buffer solution is used for cleaning the main channel, the automatic cleaning of the microfluidic detection system is realized, the structure and the control logic of the microfluidic detection system are simplified, and the volume of the microfluidic detection system is reduced.

Description

technical field [0001] The invention relates to refrigeration and freezing technology, in particular to a microfluidic detection system for a refrigerator, a control method thereof, and a refrigerator. Background technique [0002] With the improvement of people's living standards, it is usually necessary to detect pesticide residues, viruses, nutritional elements or other aspects of some food materials eaten in daily life, so as to obtain the status of food materials qualitatively or quantitatively. For example, due to the abuse of pesticides, the fruits and vegetables and agricultural by-products we buy daily may have excessive levels of pesticide residues. If the problem of excessive levels of pesticide residues in these foods is not discovered in time, human consumption will cause great harm. For another example, the breastfeeding currently advocated is the best feeding for babies only when the breastmilk has normal nutritional value. The content of elements is reduced ...

AI Technical Summary

Problems solved by technology

However, most of the existing microfluidic biochips are disposable, non-reusable, serious waste, high cost of use, and not easy to promote

Moreover, after the microfluidic biochip is integrated on the refrigerator, a new microfluidic biochip must be installed on the refrigerator every time it is used, and it must be removed from the refrigerator after use. The operation is very cumbersome

In addition, the structural integration degree of the refrigerator is relatively high, the layout is relatively compact, and the disassembly operation of the microfluidic biochip is relatively difficult.
