[0025] See also Figure 1 and Figure 2 An air pump includes a shell 1, a buffer sleeve 2 and an air pump body 3. The shell 1 is provided with a receiving cavity 11. The buffer sleeve 2 includes a sleeve 21 and a cantilever 22. One end of the cantilever 22 is connected to the sleeve 21, and the other end of the cantilever 22 is connected to the shell 1, so that the sleeve 21 is suspended in the receiving cavity 11. The buffer sleeve 2 is made of a flexible material, and the air pump body 3 is sleeved in the sleeve 21. The buffer sleeve 2 made of the flexible material can reduce the noise generated during the operation of the air pump body 3, so that the air pump has a good noise reduction effect. In addition, the buffer sleeve 2 made of the flexible material and the suspension method of the buffer sleeve 2 can reduce the probability of the buffer sleeve 2 being displaced, deformed or falling off due to collision during transportation or use, so as to reduce the impact on the noise reduction effect of the air pump.

[0026] For the above pumps, see Figure 1 and Figure 2 The housing 1 has an inner wall and an outer wall, the air pump body 3 has two end faces 31 and a side face 32 connecting the two end faces 31, the sleeve 21 has an inner peripheral surface 211 and an outer peripheral surface 212, the shape and area of ​​the inner peripheral surface 211 of the sleeve 21 are equal to the shape and area of ​​the side face 32 of the air pump body 3, the inner peripheral surface 211 of the sleeve 21 completely wraps the side face 32 of the air pump body 3, the outer peripheral surface 212 of the sleeve 21 is connected to one end of the cantilever 22, and the other end of the cantilever 22 is connected to the inner wall or outer wall of the housing 1. In the above manner, the contact area between the sleeve 21 and the air pump body 3 can be increased, so that the sleeve 21 made of a flexible material can more effectively absorb the vibration generated by the air pump body 3, so that the sleeve 21 made of a flexible material can reduce the noise generated by the vibration of the air pump body 3. In addition, by increasing the contact area between the sleeve 21 and the air pump body 3, the stability of the air pump body 3 can also be increased. It is understandable that the flexible material includes but is not limited to silicone, rubber or plastic foam, etc., which are used to slow down the transmission of sound and play a role in noise reduction.

[0027] Considering that the internal space of the housing 1 is saved and the area of ​​the receiving chamber 11 is reduced, which is conducive to the miniaturization of the air pump, in order to avoid the shortage of installation space for the cantilever 22 caused by saving the internal space of the housing 1, the cantilever 22 is referred to as Figures 2 to 4 The housing 1 is also provided with a through hole 12 connected to the receiving cavity 11, and the other end of the cantilever 22 is connected to the housing 1 after extending out of the through hole 12, wherein the side wall of the cantilever 22 abuts against the hole wall of the through hole 12 to form a limiting structure. By the above-mentioned method, the cantilever 22 is connected to the outer wall of the housing 1, which can not only save the internal space of the housing 1, which is conducive to the miniaturization and weight reduction of the air pump, but also reduce the shaking of the cantilever 22 and increase the stability of the cantilever 22.

[0028] Further, for the above cantilever 22, please refer to Figures 2 to 3 , one end of the cantilever 22 extending out of the through hole 12 is provided with a plug hole 221, and the outer wall of the shell 1 is provided with a plug post 13, and the plug post 13 is plugged into the plug hole 221. In the above manner, the cantilever 22 and the shell 1 can be connected and fixed by plugging, which is conducive to the rapid assembly and disassembly of the cantilever 22. It can be understood that in some other embodiments, the connection method between the cantilever 22 and the shell 1 also includes but is not limited to bonding, snap-on, screw-on, clamping or magnetic attraction.

[0029] In order to improve the overall stability of the sleeve 21, please refer to Figures 2 to 4 , the number of the plug posts 13 and the cantilever 22 are both four, one end of the two cantilevers 22 is connected to the two ends of one side of the sleeve 21, and one end of the other two cantilevers 22 is connected to the two ends of the other side of the sleeve 21, two plug posts 13 are located on the outer wall of one side of the shell 1, and the other two plug posts 13 are located on the outer wall of the other side of the shell 1, and one plug post 13 is plugged into a plug hole 221. Through the above four cantilevers 22, a uniformly distributed fixed structure can be formed on the periphery of the sleeve 21, providing a balanced fixed support to the sleeve 21, which is beneficial to reduce the shaking of the sleeve 21, so as to improve the overall stability of the sleeve 21. In addition, through the above four cantilevers 22, the weight and vibration load of the air pump body 3 can also be evenly dispersed, reducing the pressure on a single cantilever 22, which helps to extend the service life of the cantilever 22.

[0030] For the above case 1, see Figures 2 to 4 The housing 1 includes a first housing 141 and a second housing 151. The first housing 141 is connected to the second housing 151.

In the above manner, the housing 1 can be formed into a modular structure, which is beneficial to the manufacture of the housing 1 and the assembly of the internal structure of the housing 1.

[0031] Further, for the above-mentioned housing 1, please refer to Figures 2 to 4 The first shell 141 is provided with a first extension part 141, the second shell 151 is provided with a second extension part 151, the second extension part 151 is spaced apart from the first extension part 141, the plug post 13 is connected to the first extension part 141, the plug post 13 is located between the first extension part 141 and the second extension part 151, and the first extension part 141 and the second extension part 151 respectively abut against both ends of the plug post 13 after the plug post 13 is inserted into the insertion hole 221. In the above manner, a limiting effect can be provided to the insertion hole 221 of the cantilever 22, thereby reducing the probability of the plug post 13 falling off the insertion hole 221, which is conducive to improving the stability of the cantilever 22.

[0032] For the connection method between the first shell 141 and the second shell 151, please refer to Figures 2 to 4The air pump further includes a screw connection (not shown), which passes through the second extension portion 151 and is screwed to the plug post 13. In the above manner, the second extension portion 151 can be indirectly connected to the first extension portion 141 through the plug post 13, thereby stably connecting the first shell 141 and the second shell 151.

[0033] To further improve the noise reduction of the air pump, please refer to Figures 2 to 4 The air pump further includes a sound insulator 4, which is disposed on the inner wall of the housing 1 and wraps the sleeve 21. It is understandable that in some other embodiments, the sound insulator 4 includes but is not limited to the inner wall of the housing 1, and the sound insulator 4 only needs to be disposed inside the housing 1 and wrap the sleeve 21. For example, the sound insulator 4 is disposed on the outer wall of the sleeve 21, or the sound insulator 4 is disposed inside the sleeve 21 and the sound insulator 4 is located between the inner wall of the housing 1 and the outer wall of the sleeve 21.
