[0053] like Figures 1 to 9 As shown, this utility model provides a noise-reducing air pump device 100, including a housing 10, an air pump module 20, and a vibration damping component 30. The housing 10 has a mounting cavity 11; the air pump module 20 is at least partially disposed within the mounting cavity 11; the vibration damping component 30 is disposed between the housing 10 and the air pump module 20, so that a vibration damping space is formed between the inner wall of the housing 10 and the air pump module 20; the vibration damping component 30 includes a first connecting part 31, a second connecting part 32, and a connecting arm 33. The first connecting part 31 is disposed in the housing 10; the second connecting part 32 is disposed in the air pump module 20; the connecting arm 33 is disposed between the first connecting part 31 and the second connecting part 32; wherein, the connecting arm 33 is configured to reduce the transmission of vibration generated by the air pump module 20 to the housing 10 through its own elastic deformation, thereby reducing noise caused by resonance, making the equipment operate more smoothly and quietly, and improving the user experience.

[0054] In this embodiment, as Figures 1 to 6 As shown, the air pump device 100 also has an air outlet 50 attached to the housing 10; the air pump module 20 has an air outlet end 22; the air outlet 50 is connected to the air outlet end 22 so that the airflow generated by the air pump module 20 flows out through the air outlet 50 via the air outlet end 22. The air pump device 100 has a spatial axis that runs through the entire structure of the air pump device 100; for example, the axis of the air pump device 100 passes through the geometric center of the air outlet of the air outlet 50 and / or the geometric center of the air outlet end 22.

[0055] In this embodiment, as Figures 1 to 6 As shown, the housing 10 adopts a split structure; the housing 10 includes a first housing 13 and a second housing 14 arranged circumferentially along the air pump device 100, and the first housing 13 and the second housing 14 are detachably connected; wherein, the vibration damping member 30 is located near the connection between the first housing 13 and the second housing 14. The air outlet 50 is attached to the second housing 14.

[0056] In this embodiment, as Figures 1 to 6 As shown, the first housing 13 and the second housing 14 are detachably connected by means of snap-fit ​​15 or screws. Specifically, the first housing 13 has multiple hooks that are spaced apart around the circumference of the first housing 13; the second housing 14 has multiple slots that are spaced apart around the circumference of the second housing 14; the multiple hooks and slots are matched to fix the first housing 13 and the second housing 14, thereby facilitating the disassembly and installation of the housing 10.

[0057] In this embodiment, as Figures 1 to 6 As shown, the first housing 13 has a first receiving cavity 132 with an opening, and the second housing 14 has a second receiving cavity 141 with an opening. After the first housing 13 and the second housing 14 are assembled, the first receiving cavity 132 and the second receiving cavity 141 constitute the mounting cavity 11. Part of the structure of the air pump module 20 is located in the first receiving cavity 132, and another part of the structure is located in the second receiving cavity 141.

[0058] In this embodiment, as Figures 1 to 6 As shown, the end of the first housing 13 facing the second housing 14 has a positioning groove 131; the edge of the second housing 14 facing the first housing 13 is correspondingly embedded in the positioning groove 131, forming a circumferential limiting fit, which ensures connection reliability and facilitates quick disassembly and maintenance. The positioning groove 131 is arranged in a ring shape.

[0059] In this embodiment, as Figures 3 to 5 as well as Figure 7As shown, the vibration damping component 30 is made of elastic materials such as rubber or silicone, which further absorbs high-frequency vibrations through the material properties, reduces the transmission efficiency of vibration to the shell 10, and thus significantly reduces resonance noise.

[0060] In this embodiment, as Figures 3 to 5 as well as Figure 7 As shown, one of the housing 10 and the first connecting part 31 is provided with a plug hole 311, and the other is provided with a plug member 12; the plug member 12 is configured to extend into the plug hole 311 to attach the first connecting part 31 to the housing 10. The plug-in design of the housing 10 and the first connecting part 31 simplifies the assembly process and facilitates quick disassembly and subsequent maintenance.

[0061] Specifically, the connector 12 is fixed to the first housing 13; the connector 12 is located at the end of the first housing 13 facing the second housing 14. One end of the connector 12 is integrally formed with the first housing 13, and the other end faces the second housing 14 and extends along the axis of the air pump device 100; the opening of the insertion hole 311 faces the first housing 13, and the insertion hole 311 extends along the axis of the air pump device 100. There are multiple connectors 12, which are arranged circumferentially around the air pump module 20; there are also multiple insertion holes 311, which mate with corresponding connectors 12.

[0062] In this embodiment, as Figures 3 to 5 as well as Figure 7 As shown, the second connecting portion 32 is annular and is sleeved on the outside of the air pump module 20. The air pump module 20 has a limiting step 21, and at least the second connecting portion 32 of the vibration damping member 30 abuts against the limiting step 21. The outer wall of the air pump module 20 is provided with an annular limiting step 21, and at least a portion of the second connecting portion 32 forms an axial abutment with the limiting step 21, which can realize a reliable connection between the vibration damping member 30 and the air pump module 20. The limiting step 21 effectively prevents the air pump module 20 from axial displacement caused by vibration during operation.

[0063] In this embodiment, as Figures 3 to 5 as well as Figure 7 As shown, the connecting arm 33 extends along an axis perpendicular to the air pump device 100, such that the first connecting portion 31 and the second connecting portion 32 are spaced apart. The connecting arm 33 is integrally formed with the first connecting portion 31 and the second connecting portion 32 to reduce the processing difficulty of the vibration damping component 30 and to enhance the structural strength of the vibration damping component 30.

[0064] In this embodiment, as Figures 3 to 5 as well as Figure 7As shown, along the axis of the air pump device 100, the opening of the insertion hole 311 and the limiting step 21 are located on both sides of the vibration damping member 30, respectively. The limiting step 21 faces away from the air outlet 50 of the air pump device 100 to ensure the connection stability between the vibration damping member 30 and the housing 10.

[0065] In this embodiment, as Figures 3 to 5 as well as Figure 7 As shown, the air pump device 100 also includes a connecting member 40, which is configured to connect the air outlet 22 to the air outlet 50. The connecting member 40 has a connecting channel 41, into which both the air outlet 22 and the air outlet 50 extend. Along the extending direction of the connecting channel 41, the air outlet 22 and the air outlet 50 are spaced apart to prevent vibrations generated during the operation of the air pump module 20 from being transmitted from the air outlet 22 to the housing 10.

[0066] In this embodiment, as Figures 3 to 5 as well as Figure 7 As shown, the connecting member 40 is located inside the second housing 14; the connecting member 40 and the vibration damping member 30 form a vibration damping space between the air pump module 20 and the inner wall of the housing 10. The connecting member 40 is made of vibration damping material; the connecting member 40 ensures smooth airflow transmission and can effectively absorb the vibration energy generated by the air pump module 20 during operation through elastic deformation.

[0067] In this embodiment, as Figures 1 to 2 As shown, the air pump device 100 also includes a mounting component 60, which is configured to connect the air pump device 100 to external equipment and to maintain a certain distance between the air pump device 100 and the external equipment. This effectively isolates the transmission path of vibrations generated by the operation of the air pump device 100 to the external equipment, reducing additional noise caused by resonance. At the same time, the spacing design avoids direct rigid contact between the air pump module 20 and the external equipment, reducing secondary noise generated by vibration energy transmission through the structure. In addition, the mounting component 60 facilitates independent suspension or positioning of the air pump device 100, reduces installation accuracy requirements, improves on-site assembly efficiency and ease of later maintenance, and comprehensively extends the overall service life of the equipment.

[0068] In this embodiment, as Figures 1 to 2 as well as Figures 8 to 9 As shown, there are multiple mounting components 60; the multiple mounting components 60 are distributed on the same side of the housing 10. The mounting components 60 are made of vibration-damping material, and the elastic deformation of the mounting components 60 effectively absorbs the vibration energy between the air pump device 100 and the external equipment, reducing the noise caused by structural resonance; for example, the material of the mounting components 60 is rubber or silicone.

[0069] In this embodiment, as Figures 1 to 2 as well as Figures 8 to 9As shown, one of the mounting component 60 and the housing 10 has a first mounting portion 16, and the other has a second mounting portion 61. The first mounting portion 16 and the second mounting portion 61 are interlocked to assemble the mounting component 60 into the housing 10. The cooperation between the first mounting portion 16 and the second mounting portion 61 enables rapid assembly, ensuring the stability of the gap between the air pump device 100 and external equipment, and avoiding displacement or loosening caused by vibration. At the same time, the mounting component 60 is assembled with the housing 10 through a plug-in structure, which simplifies the installation and disassembly process, facilitates later maintenance or replacement, and improves the flexibility and reliability of equipment use.

[0070] In this embodiment, as Figures 1 to 2 As shown, the first mounting part 61 has a mounting hole 611; the first mounting part 16 is configured to extend into the mounting hole 611 to assemble the mounting member 60 to the housing 10. The insertion and engagement of the first mounting part 61 with the mounting hole 611 enables quick assembly, and the mounting part 16 forms a stable mechanical connection after extending into the mounting hole 611. The first mounting part 16 is fixedly connected to the housing 10 and is bent; a limiting protrusion 161 is provided at the end of the first mounting part 16 away from the housing 10. The mounting hole 611 is provided through the mounting member 60; when the first mounting part 16 extends out through the mounting hole 611, the limiting protrusion 161 and the mounting member 60 form a snap-fit ​​engagement, effectively preventing the first mounting part 16 from coming out of the mounting hole 611 and ensuring the stability of the connection between the mounting member 60 and the housing 10.

[0071] In another embodiment, such as Figures 8 to 9 As shown, the first mounting portion 16 includes a snap-fit ​​portion 162; the second mounting portion 61 includes a slot 612; the snap-fit ​​portion 162 engages with the slot 612 to facilitate quick assembly of the first mounting portion 61 with the mounting hole 611. The slot 612 is annularly disposed in the second mounting portion 61; the snap-fit ​​portion 162 has an inlet to facilitate the entry and exit of the mounting component 60.

[0072] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0073] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
