Abstract

Disclosed is a fan structure for adjusting a negative pressure of a pressure measuring interface, which comprises: a volute (1) and a pressure measuring interface (2). A cavity (11) for accommodating a wind wheel is formed at the middle of the volute (1), a volute through hole (12) is set on the volute (1), a pressure measuring through hole (21) is formed at the middle of the pressure measuring interface (2), the pressure measuring interface (2) is mounted on the volute (1), the pressure measuring through hole (21) communicates with the cavity (11), a turbulence block (22) protrudes from an end surface of the pressure measuring interface (2), and the turbulence block (22) is located in the cavity (11) and can rotate around the volute through hole (12) with the pressure measuring interface (2). By changing a structure of an even tail of a conventional pressure measuring interface, a turbulence block protrudes from an end surface of the pressure measuring interface, and by means of a principle of uneven air distribution, the turbulence block changes the direction of the airflow in the pressure measuring interface, thereby influencing the negative pressure output value of the pressure measuring interface. The angle of the turbulence block of the pressure measuring interface is changed through rotation to obtain different negative pressure output values, thereby meeting requirements for negative pressure output values of different fans.
