[0033] Please see Figure 5As shown, in this embodiment, the housing mechanism 21 includes a main housing 211, a first end cap 212, and a second end cap 213. The main housing 211 is a hollow cavity with openings at opposite ends. The circuit board 22, the air pump mechanism 23, and the sound-absorbing cotton 24 are respectively disposed in the main housing 211. The first end cap 212 and the second end cap 213 are respectively disposed at the openings at opposite ends of the main housing 211.

The control technology used is existing technology, so the specific control process and product model are not described here, as long as they meet the requirements of this application.

[0035] Please see Figure 3 , Figure 5 and Figure 6 As shown, in this embodiment, the air pump mechanism 23 includes a brushless motor 231, an eccentric wheel 232, a transmission link 233, a cylinder body 234, and a fan blade 235.

The cylinder body 234 transports the external gas to the air storage tank body 11 in sequence through the silencer 2111 and the air inlet pipe structure 14 for storage, thereby realizing the air storage operation of the silent air storage pump 1. Then, it charges other equipment through the air outlet pipe structure 15. While driving the eccentric wheel 232 to rotate, the brushless motor 231 also drives the fan blade 235 to rotate, thereby dissipating the heat in the housing mechanism 21 to the outside atmosphere through multiple heat dissipation holes 2131.
