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 in size, easy to control and portable; the cost is low; when the pressure gauge assembly is used in the inflator, the pressure gauge assembly is arranged in the thickness direction of the inflator such that the part, without internal assemblies, of a front surface of the inflator can be emptied, and the size and the cost are saved.

    本发明提供一种压力表组件、打气机、电路及打气方法,压力表组件包括:显示屏,用于接收控制主板的控制并显示压力的数值;压力传感器,用于检测气压并将检测到的气压信号传递给控制主板;控制主板,用于接收气压信号并根据气压信号控制所述显示屏实时显示压力的数值;或,采集旋转编码器旋转产生的数字信号压力并控制显示屏显示设置充气气压值;旋转编码器,与控制主板电连接。将旋转编码器引入打气机,将旋转编码器与显示屏巧妙结合在一起,所以压力表组件的体积小,容易操控,便携;成本低;将压力表组件用到打气机时,压力表组件设置在打气机的厚度方向,所以打气机正面不设置内部组件的地方可以做空处理,节省体积,节省成本。
