AI Technical Summary
Existing portable vacuum pumps suffer from high-frequency vibration and noise during operation, which affects the user experience.
A first buffer pad and a second buffer pad are set on both sides of the vacuum pump, and the vacuum head and the housing are integrally molded into silicone material. Combined with structures such as convex rings, raised surfaces, ribs and ribs, the connection stability is enhanced and vibration and noise are reduced.
It effectively reduces the vibration and noise of portable vacuum pumps, improving user comfort and stability.
