[0037] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention.

[0038] Reference Figure 1 and Figure 2As shown, in one embodiment, a sound insulation structure for a micro air pump is provided, comprising an air pump assembly 100, an inner support 200, an inner air bag 300, an outer support 400, and an outer air bag 500. The inner support 200 has a first mounting cavity, within which the air pump assembly 100 is fixedly mounted. The inner air bag 300 is hermetically mounted on the outer surface of the inner support 200. The outer support 400 has a second mounting cavity, within which the inner air bag 300 is fixedly mounted and supported. The outer air bag 500 is tightly fitted around the outer support 400, forming a sealed cavity 600 between the inner air bag 300 and the outer air bag 500. The outer air bag 500 has a nozzle 501 and a sealing plug 502. The nozzle 501 is used to extract air from the cavity 600, and the sealing plug 502 is used to seal the nozzle 501 after the air in the cavity 600 is extracted, thereby creating a vacuum-sealed cavity 600. A vacuum does not propagate sound waves, so the air around the air pump assembly 100 is removed by vacuuming, minimizing the paths for sound transmission. This significantly reduces noise, resulting in a superior silencing effect and a better user experience.

[0039] Reference Figure 3 As shown, in one example, the air pump assembly 100 includes an air pump 110 and a suspension support 120, with the air pump 110 suspended and fixed inside the suspension support 120. The air pump 110 can be a micro air pump in a smart pillow. Specifically, the suspension support 120 includes an elastic connector 123, a liner 121, and a suspension frame 122. The liner 121 is elastically suspended on the suspension frame 122 via the elastic connector 123. The liner 121 has a support panel for placing the air pump 100. The air pump 110 is fixed via the liner 121, and the elastic connector 123 is suspended within the suspension frame 122. Suspending the air pump 110 minimizes contact with other components. The air pump 110 transmits sound through the very thin solid medium elastic connector 123, thereby reducing the degree of sound transmission.

[0040] Reference Figure 4 As shown, in a specific example, the air pump 110 is cylindrical, and the supporting panel is configured as a first curved panel 1211 that is in contact with the lower side of the air pump 110. The first curved panel 1211 extends upward, and a hook 1212 is formed at the upper end of the first curved panel 1211. The hook 1212 is connected to the lower end of the elastic connector 123. Optionally, the hook 1212 can be provided at the four corners of the upper end of the first curved panel 1211, and the specific location of the hook 1212 is not limited herein.

[0041] Reference Figure 4As shown, in a specific example, the suspension bracket 122 is configured as a second curved panel 1221 extending upward, and a suspension column 1222 is formed on the upper end of the second curved panel 1221. Optionally, the suspension columns 1222 are provided at the four corners of the upper end of the second curved panel 1221, and the number of elastic connectors 123 is set to 4 corresponding to the suspension columns 1222. The upper end of the elastic connector 123 is connected to the suspension column 1222 and hooks the suspension column 1222. The specific position of the suspension column 1222 at the upper end of the second curved panel 1221 is not limited here, and can be provided under the condition that the air pump 110 can be stably suspended. The arc radius of the second curved panel 1221 is greater than the arc radius of the second curved panel 1211. As shown Figure 3 There is enough space inside the suspension frame 122 to accommodate the card liner 121 and the air pump 110. The card liner 121 is suspended at a certain height inside it. Except for being connected through the elastic connecting piece 123, there is no other contact with it, so as to minimize the path of sound transmission.

[0042] Reference Figure 3 As shown, in one example, the first mounting cavity is configured as a cylindrical cavity with a single-side opening. A limiter 210 is disposed within the first mounting cavity. The limiter 210 can be configured as a raised plate on the inner wall of the first mounting cavity. The limiter 210 abuts against the upper edge of the first curved panel 1221 to limit the movement of the hanger 122 within the inner support, thereby securing the air pump assembly 100 within the inner support 200.

[0043] Reference Figure 2 As shown, in one example, the end 111 of the air pump 110 is connected to a silicone tube 112. The end 111 is the pump outlet of the air pump 110, and the silicone tube 112 is inserted for air outlet.

[0044] In one example, the inner air bag 300 further includes a PVC tube 113 sleeved on the outer periphery of the silicone tube 112. The outer diameter of the silicone tube 112 is smaller than the inner diameter of the PVC tube 113. A first sealing edge 310 is formed on the circumference of the inner air bag 300. The first sealing edge 310 near the silicone tube 112 corresponds to the position Figure 4 The sealing opening 311 shown is press-sealed with the PVC tube 113 at the sealing opening 311. The PVC tube 113 and the inner air bag 300 are pressed together, and the air pump 110 inside is relatively sealed by the inner air bag 300.

[0045] Reference Figure 1As shown, in one example, a second sealing edge 510 is formed around the outer air bag 500. This second sealing edge 510, located near the silicone tube 112, is pressed and sealed against the PVC tube 113. The outer air bag 500 is sealed, creating a sealed cavity 600 between the inner air bag 300 and the outer air bag 500. A vacuum pump is used to evacuate air from cavity 600 through nozzle 501, which is then sealed with silicone plug 502, creating a vacuum-insulated air pump structure. The micro air pump transmits sound through a very small solid structure, significantly reducing noise.

[0046] Reference Figure 5 As shown, in one example, a plurality of fixing posts 410 are provided on the bottom plate of the second mounting cavity, and a plurality of through-holes 312 are provided on the first sealing edge 310. Screws are passed through the through-holes 312 and fixed in the fixing posts 410. Optionally, after the inner air bag 300 is wrapped around the outer surface of the inner bracket 200 and fixed using the fixing posts 410, the inner air bag 300, the inner bracket 200, and the air pump assembly 100 therein can be stabilized in the outer bracket 400, restricting their movement.

[0047] This embodiment provides a sound insulation structure for a micro air pump. The internal spring-suspended air pump is combined with a vacuum isolation air pump to achieve an excellent vacuum effect. It is suitable for products with extremely high requirements for quietness. There is no limit on its specific size and it can be adjusted at will according to product requirements.
