[0002] Currently, many household or outdoor appliances require air pumps as air supply devices, such as aroma diffusers based on the Venturi effect, air mattresses, outdoor air pumps, and aquarium air supply devices.

[0003] In the existing technology, air pumps typically use a motor to drive an impeller to rotate, thereby generating airflow and providing air pressure to the outside world. Due to factors such as motor operation, motor vibration, impeller-driven airflow, and impeller vibration, air pumps usually generate a certain amount of vibration and noise.

[0004] As people's demand for low-noise environments becomes more widespread, the noise problem of air pumps during operation has become particularly prominent. Seeking noise reduction solutions for air pumps has become one of the key research and development directions in the industry. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a novel air pump structure, which aims to provide a structural solution for vibration reduction and noise reduction of the air pump, and solve the noise problem of the air pump during operation.

[0033] This utility model surrounds the air pump body 1 within the receiving cavity 3. The housing 2 provides initial sound insulation and noise reduction. The air pump body 1 is secured within the receiving cavity 3 by the first damping body 5 and the second damping body 6. The first damping body 5 and the second damping body 6 can buffer the vertical vibration of the air pump body 1 during operation, avoiding noise caused by the vertical vibration of the air pump body 1.

Moreover, the above solution can be achieved simply by setting the housing 2, the first damping body 5, and the second damping body 6, making the structure simple.

[0034] In a preferred embodiment, the housing 2 includes a main housing 21 and a first end cap 22. One end of the main housing 21 is detachably connected to the first end cap 22 to form a receiving cavity 3, which facilitates the installation of the air pump body 1 in the receiving cavity 3. The other end of the main housing 21 is provided with a wiring through hole 7 for the passage of electrical cables to connect to the electrical connection pin 8 on the air pump body 1. In this embodiment, the first damping body 5 is disposed between the first end cap 22 and the air pump body 1, and the second damping body 6 is disposed between the electrical connection pin 8 and the housing wall of the main housing 21 where the wiring through hole 7 is provided. The first damping body 5 abuts against the first end cap 22, and the second damping body 6 abuts against the housing wall of the main housing 21 where the wiring through hole 7 is provided. In order to buffer and absorb the vertical vibration of the air pump body 1 during operation, the first damping body 5 and the second damping body 6 need to have compression and rebound properties.
