The air flow sensor 30 is generally provided with three conductive wires 31, a first conductive wire 311, a second conductive wire 312, and a third conductive wire 313, wherein the first conductive wire 311 is electrically connected to the positive pole of the battery 14, the second conductive wire 312 is configured as the positive pole of the output, and the third conductive wire 313 is configured as the negative pole of the output and is simultaneously electrically connected to the negative pole of the battery 14.

The airflow sensor 30 is fixed inside the accommodating cavity of the sealing seat 50, and a lead structure is arranged on the sealing seat 50, and is used for three leads 31 on the airflow sensor 30 to pass through and guiding the direction of the leads 31. The lead structure is generally configured as a lead perforation that is disposed through the sealing seat 50, so that when the three wires 31 of the airflow sensor 30 cannot fully occupy the inner space of the perforation, the gap in the perforation that is not occupied by the wires 31 further communicates with both sides of the airflow sensor 30, thereby affecting the sensitivity of the airflow sensor 30. In fact, when there is a crossover between the three wires of the airflow sensor 30, the three wires 31 are extremely likely to form a gap inside the lead penetration hole after passing through the lead penetration hole, thereby affecting the sensitivity of the airflow sensor 30.

In an embodiment of the present application, the lead structure is optimized, so that the lead structure can ensure the air tightness of the lead structure while being led out by the plurality of wires 31 connected to the airflow sensor 30, and the air leakage of the lead structure is prevented.

Further, since the sealing seat 50 is made of a flexible silica gel material and the end cap 12 is made of a hard plastic material, the matching portion 125 is also made of a hard plastic material, so that sufficient extrusion interference can be formed between the lead groove 53 and the matching portion 125, thereby improving the air tightness of the lead structure.

Referring to fig. 4, the sealing seat 50 includes a peripheral wall 52, and the peripheral wall 52 encloses to form an accommodating chamber 51.

The three bone positions are radially protruded relative to the inner wall of the second receiving groove 123, and the width of the three bone positions is substantially the same as that of the three lead grooves 53, wherein the groove width of each lead groove 53 is substantially the same as the outer diameter of each wire 31 received therein so as not to form a gap, and the three bone positions are spaced apart by a distance substantially the same as that of the three lead grooves 53.

In the above embodiment, three wires 31 are provided on the airflow sensor 30, and in alternative embodiments, the number of the wires 31 on the airflow sensor 30 can be adjusted as required, for example, five wires 31 are provided on the airflow sensor 30 with the charging function, five wire guiding grooves 53 are correspondingly provided on the sealing seat 50, and five bone positions are provided on the inner wall of the end cap 12 for cooperation.

In a preferred embodiment, a guiding structure 126 is further disposed on the matching portion 125 on the inner wall of the end cap 12, and the guiding structure 126 enables the wire 31 to keep close contact with the matching portion 125, so as to prevent a gap from being formed due to failure of close contact between the wire 31 and the matching portion 125. When the lead wire 31 is configured in a cylindrical shape, the guiding structure 126 is configured in an arc-shaped curved surface, the arc-shaped curved surface wraps a part of the side surface of the lead wire 31, and the other part of the surface of the lead wire 31 is attached to the inner wall of the lead slot 53, so that the lead slot 53 and the matching part 125 cooperate to form a seamless attached wrapping on the lead part accommodated in the lead slot 53, and the formation of a gap is effectively avoided.
