Abstract

A blower, including a scroll casing, a fan impeller, a motor, and a pressure measuring connector. The scroll casing includes a chamber, an air inlet, and an air outlet. The air inlet and the air outlet communicate with the chamber. The motor is disposed on the scroll casing. A drive end of the motor is inserted into the chamber and is connected to the fan impeller. The pressure measuring connector is disposed on the scroll casing. A channel is disposed in the pressure measuring connection, and the channel communicates with the chamber. The channel includes a first subchannel and a second subchannel. The first subchannel communicates with the second subchannel, and an inner diameter of the first subchannel is larger than an inner diameter of the second subchannel.
