Shock absorption and heat insulation structure of air pump

An air pump is installed in a shell, the shell comprises a bottom shell, an upper shell and a top cover, an opening of the bottom shell faces upwards, an air pump installation base is arranged in the middle of the bottom shell, a first damping and heat insulation coaming surrounding the air pump installation base is further arranged in the bottom shell, an opening of the upper shell faces downwards, and a second damping and heat insulation coaming is arranged on the lower side of a top plate. A heat dissipation window is arranged on one side of the upper shell, a fan installation clamping groove corresponding to the heat dissipation window is formed in the second shock absorption and heat insulation coaming, and the inner area of the second shock absorption and heat insulation coaming is communicated with the heat dissipation window at the fan installation clamping groove so as to facilitate air flowing; the gap between the first damping and heat-insulating coaming and the outer wall of the bottom shell and t
