Microfluidic flow channel structure and microfluidic chip

A microfluidic flow channel structure, comprising a main chamber, the main chamber comprises at least two division zones and a reaction zone, and the at least two division zones are respectively connected with the reaction zone, wherein:

• a division zone of the at least two division zones comprises a first division wall, and the first division wall is provided with an opening for liquid inlet;
• a diversion structure is arranged at the opening of the division zone of the at least two division zones, and the diversion structure at least comprises a first diversion wall, which is arranged opposite the first division wall;
• a first division channel is formed between the first diversion wall and the first division wall;
• the opening serves as a liquid inlet of the first division channel, and the first division channel comprises at least two liquid outlets;
• each division zone is in a single-input and double-output structure;
• the at least two division zones are adjacent to form four liquid paths for sample liquid to enter the reaction zone;
• the reaction zone is a conical reaction zone, and the conical reaction zone is in an outlet region of the single-input and double-output structure;
• and
• the microfluidic flow channel structure further comprises a liquid outlet zone, and the liquid outlet zone comprises a plurality of liquid outlet channels, and each liquid outlet channel is connected with the reaction zone.
