[0033] In the technical solution provided by this utility model, the front limiting part 3 and the rear limiting part 4 not only serve to fix the pneumatic power component 2, but the design of the two notches allows the pneumatic power component 2 to have a certain floating space in the first direction 7, absorbing the high-frequency vibration generated when the piston pushes back and forth. At the same time, the shape and material of the notches can effectively absorb and disperse the vibration energy, thereby significantly reducing the noise level.

[0034] Please refer to Figures 1 to 5In this embodiment, the inflation power assembly 2 includes an inflation tube 21, a drive motor 22, a transmission structure 23, and a fixed base 24. The drive motor 22, the transmission structure 23, and the piston inside the inflation tube 21 are sequentially connected. The transmission structure 23 is mounted on the fixed base 24, which abuts against the first notch 31. The drive motor 22 abuts against the second notch 41. The first notch 31 and the second notch 41 respectively raise the mounting positions of the fixed base 24 and the drive motor 22 in the power chamber 11, reducing the frictional force during operation and thus reducing the noise generated during the gas output process of the inflation power assembly 2.

[0035] Please refer to Figures 1 to 5 In this embodiment, at least one support column 5 is also included. The support column 5 is disposed in the power chamber 11 and supports the bottom surface of the fixed base 24. The main function of the support column 5 is to support the bottom surface of the fixed base 24, providing additional support for the inflation power assembly 2. This design not only enhances the stability of the entire power assembly and reduces noise caused by vibration, but also optimizes the power transmission path and improves inflation efficiency.

[0036] Please refer to Figures 1 to 5 In this embodiment, a pair of reinforcing ribs 51 are connected around the support column 5. The two reinforcing ribs 51 are arranged perpendicularly to each other. This structure can significantly improve the bending and torsional resistance of the support column 5, enabling it to better withstand various forces and vibrations generated by the pneumatic power assembly 2 during operation, thereby helping to reduce noise caused by vibration and extending the service life of the air pump.

[0037] Please refer to Figures 1 to 5 In this embodiment, three front limiting parts 3 are equidistantly arranged in the power chamber 11 to ensure stable support of the inflation power component 2 in the front-rear direction. They also improve the overall stability of the structure by distributing the load, and the gap between the front limiting parts 3 is conducive to internal air circulation, thereby enhancing the heat dissipation capacity of the inflation power component 2. A reinforcing inclined surface 32 is provided on the side of the front limiting part 3 away from the first notch 31 to counteract the pressure from the first notch 31 and improve the structural strength of the front limiting part 3.

The second notch 41 is provided with a relief slope 411 for placing the drive motor 22, which can make the drive motor 22 more securely fixed between the two rear limiting parts 4. The rear limiting part 4 is provided with a thrust-resistant reinforcing block 42 on the side away from the second notch 41 to counteract the thrust from the second notch 41.

[0039] Please refer to Figures 1 to 5In this embodiment, a motor clearance groove 111 is provided at the bottom of the power chamber 11. The motor clearance groove 111 is located between the two rear limiting parts 4. The installation size of the drive motor 22 may be large. In order to reduce the contact area of ​​the bottom surface of the power chamber 11 and reduce the friction, the motor clearance groove 111 is provided.

[0040] Please refer to Figures 1 to 5 In this embodiment, the side wall of the power chamber 11 is provided with supporting ribs 112, and the drive motor 22 abuts against the supporting ribs 112. These ribs not only enhance the structural strength of the power chamber 11, but also provide additional support for the drive motor 22. At the same time, they can prevent the drive motor 22 from colliding with the side wall of the power chamber 11 and reduce noise during use.
