When an air pressure during inflation is between 95% of the preset saturation pressure and 100% of the preset 2026201011   12 Feb 2026 saturation pressure, the third lamp body flashes slowly, which may prompt the user that the air pump needs to be turned off, or prompt the user that the air pump will automatically stop working soon and the next tire inflation operation may be carried out. The fourth lamp body is configured to display a deflation state. The fourth lamp body is a 5 blue light lamp. When the blue light lamp flashes slowly, it may prompt the user that it is currently in the deflated state. The fifth lamp body is configured to display a resting state. The fifth lamp body may be a white light lamp. When the white light lamp is constantly on, it may prompt the user that it is currently in the resting state (non-working state). The fifth lamp body may also be configured as a 0 breathing lamp, a chasing lamp, a multi-color constant lamp, etc. The sixth lamp body is used to display the abnormal state. The sixth lamp body may be a red light lamp. When the red light lamp is constantly on, it may prompt the user that the air pump is in an abnormal state, such as overheating, hardware errors, excessive air pressure and other faults, facilitating the user to take measures as soon as possible. 15        In this embodiment, the control panel 4 has a display panel 41, a mode indicator light 45, a button 42, a first interface 43 and a second interface 44.
