The invention provides a pressure gauge assembly, an inflator, a circuit and an inflation method, and the pressure gauge assembly comprises a display screen which is used for receiving the control ofa control mainboard and displaying the numerical value of pressure; a pressure sensor used for detecting air pressure and transmitting a detected air pressure signal to a control mainboard; the control mainboard used for receiving the air pressure signal and controlling the display screen to display the numerical value of the pressure in real time according to the air pressure signal; or collecting the digital signal pressure generated by the rotation of a rotary encoder and controlling the display screen to display and set an inflation air pressure value; and the rotary encoder which is electrically connected with the control mainboard. The rotary encoder is introduced into the inflator, and the rotary encoder and the display screen are ingeniously combined together such that the pressuregauge assembly is small i
