a base 101 embedded in the breathing conduit, wherein the breathing conduit is used for interfacing with the mouth and nose of a human body; the base 101 and the wall of the breathing tube form a sealed whole, and the base 101 is made of hard materials such as ABS (Acrylonitrile butadiene Styrene copolymers) or flexible materials such as silica gel; a flexible circuit 102 is attached to the bottom surface of the base 101, and a micro-flow sensor is connected in the flexible circuit 102, wherein the micro-flow sensor is an MEMS (micro electro Mechanical Systems); the micro-flow sensor is arranged in the breathing pipeline 200, a signal connecting line 103 is welded on the flexible circuit 102, and the signal connecting line 103 penetrates out from the upper part of the base 101.

In this embodiment, when air flows through the breathing conduit, the micro flow sensor disposed in the breathing conduit detects the air flow in the breathing conduit, converts the detected air flow into current data, and outputs the current data to the external control circuit through the signal connection line 103, so as to obtain the air flow data. And because the micro-flow sensor is attached to the bottom surface of the base 101 through the flexible circuit 102, the structure is more compact and small, and the micro-flow sensor is convenient to be integrated into breathing pipelines with various shapes.

In this embodiment, a protrusion 104 protruding toward the bottom surface of the base 101 is disposed on the bottom surface of the base 101, the area of the protrusion 104 is smaller than that of the base 101, and the flexible circuit 102 is attached to the surface of the protrusion 104.
