Due to the sound generated during the inflation and deflation process and the noise generated inside and outside, the existing device generally only has an inflation support structure and does not specifically install an effective sound insulation and isolation part. Therefore, when the device is in use, the internal environment is noisy, affecting the actual use experience of the device. Summary of the Invention

[0021] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0022] Embodiment

[0023] Figures 1-4 The figure shows a schematic diagram of the overall structure as a specific embodiment of the present utility model. Figures 1-4Among them, a micro high-pressure oxygen chamber sound insulation device includes a protective outer chamber 1, an external sound insulation mechanism installed on the outer side of the protective outer chamber 1, and an internal sound insulation mechanism installed on the inner side of the protective outer chamber 1.

[0024] The external sound insulation mechanism includes a rebound ellipse 102 installed on the outer surface of the protective outer chamber 1, a support chassis 101 installed at the lower end of the protective outer chamber 1, and a reinforcement plate 103 installed at the upper end of the support chassis 101. The reinforcement plate 103 is inserted into the protective outer chamber 1.

[0025] The internal sound insulation mechanism includes a sound insulation inner chamber 2 for isolating the protective outer chamber 1 from the outside, a sound absorption groove 201 for internal sound absorption, a middle rebound chamber 205 for sound rebound, an inner sound absorption chamber 204 and an outer sound absorption chamber 206 for overall adsorption of internal and external sounds respectively. The sound insulation inner chamber 2 is installed on the inner wall of the protective outer chamber 1, and the sound absorption groove 201 is opened on the inner wall of the sound insulation inner chamber 2.

[0026] Under the isolation of the external sound by the external sound insulation mechanism and the adsorption of the internal sound by the internal sound insulation mechanism, and at the same time under the combined use of the external sound insulation mechanism and the internal sound insulation mechanism, a single mechanism can simultaneously isolate and adsorb the sounds inside and outside the device, so as to achieve the effect of comprehensive sound insulation for the whole device. Specifically, under the rebound effect of the rebound ellipse 102 on the outer side of the protective outer chamber 1 when transmitting external sounds, and under the action of the reinforcement plate 103 itself being a thickened layer, the sounds on the outer side of the device are isolated to prevent the sounds from being transmitted to the inside of the device. At the same time, under the isolation of the sound insulation inner chamber 2 itself, the internal and external sounds can be synchronously isolated, effectively preventing the transmission of sounds on both sides of the device. Then, under the sound absorption effect of the sound absorption groove 201, the sounds inside the device are adsorbed and then transmitted to the inside of the inner sound absorption chamber 204. Through the adsorption of the inner sound absorption chamber 204, the transmission of sounds is reduced, and under the rebound effect of the middle rebound chamber 205 on the sounds, the sounds on both the inner and outer sides can be rebound and transmitted to the inner sound absorption chamber 204 and the outer sound absorption chamber 206 respectively. Thus, under the simultaneous adsorption of the inner sound absorption chamber 204 and the outer sound absorption chamber 206, the sounds on both sides are isolated and adsorbed, further preventing the sounds from being transmitted to the other side, providing comprehensive sound insulation support for both inside and outside the device.

[0027] Figure 1 Shown is a schematic cross-sectional structure diagram of the internal sound insulation mechanism as a specific embodiment of the present utility model. Figure 1 Among them, the internal sound insulation mechanism further includes a sound absorption layer 202 installed inside the inner sound absorption chamber 204, and the sound absorption layer 202 is used for adsorbing the sounds on one side of the middle rebound chamber 205 and one side of the sound absorption groove 201.

[0028] With the sound absorption and support of the sound absorption layer 202, it is possible to absorb the sound flowing from one side of the sound absorption groove 201. At the same time, it can uniformly absorb the sound rebounding from one side of the middle rebounding chamber 205 and the sound flowing in from the outside of the device, improving the sound insulation intensity of the device.

[0029] Figure 1 Shown is a schematic cross-sectional structure diagram of the internal sound insulation mechanism as a specific embodiment of the present invention. Figure 1 In it, the internal sound insulation mechanism further includes a rebounding layer 203 installed inside the middle rebounding chamber 205. The rebounding layer 203 is used for rebounding the sound on the side of the inner sound absorption chamber 204 and the side of the outer sound absorption chamber 206.

[0030] With the rebounding and support of the sound by the rebounding layer 203, the middle rebounding chamber 205 can rebound the sound flowing from one side of the inner sound absorption chamber 204 and can also rebound the sound flowing from one side of the outer sound absorption chamber 206, so that the sounds on both sides flow in the opposite direction. At the same time, it resists the sound that is flowing, causing them to cancel each other out, further improving the sound insulation effect of the device.

[0031] Figure 1 Shown is a schematic cross-sectional structure diagram of the internal sound insulation mechanism as a specific embodiment of the present invention. Figure 1 In it, a sound absorption layer 202 is installed inside the outer sound absorption chamber 206, and the sound absorption layer 202 is used for absorbing the sound on the side of the middle rebounding chamber 205 and the sound outside the protective outer cabin 1.

[0032] With the sound absorption and support of the sound by the sound absorption layer 202, the absorption effect of the outer sound absorption chamber 206 on the sounds flowing on both sides is improved, so that it combines with the middle rebounding chamber 205 and the inner sound absorption chamber 204 to form a multi-layer sound insulation layer, improving the sound insulation performance of the internal sound insulation mechanism.

[0033] Figure 2 Shown is a schematic three-dimensional structure diagram of the interior of the device as a specific embodiment of the present invention. Figure 2 In it, the reinforcing plate 103 is inserted into the sound insulation inner cabin 2 at the same time. The reinforcing plate 103 extends into the interior of the sound insulation inner cabin 2, and the reinforcing plate 103 is used for sound insulation at the lower end of the sound insulation inner cabin 2.

[0034] With the support of the reinforcing plate 103 from the bottom of the device, sound insulation is carried out on the lower part of the sound insulation inner cabin 2 and the protective outer cabin 1, thereby improving the effect of further enhancing the sound insulation intensity of the device.

[0035] Figure 1 and Figure 4 Shown is a schematic structure diagram of the sound insulation method as a specific embodiment of the present invention. Figure 1 and Figure 4Among them, the rebound ellipse 102 and the rebound layer 203 have shapes with sound rebound, and the sound absorption layer 202 is made of materials with sound absorption properties.

[0036] By setting the rebound ellipse 102 as a spherical shape, it can rebound the external sound. By setting the inside of the rebound layer 203 as an uneven structure, it can effectively rebound the sound on both sides. And by setting the sound absorption layer 202 as materials such as mineral wool and glass wool, its sound absorption effect is ensured.

[0037] Working principle: First, under the rebound effect of the rebound ellipse 102 on the outside of the protection outer cabin 1 when transmitting external sound, and with the strengthening plate 103 itself being a thickened layer, the sound on the outside of the device is isolated to prevent the sound from being transmitted into the device. At the same time, under the isolation of the sound insulation inner cabin 2 itself, the internal and external sounds can be synchronously isolated, effectively preventing the transmission of sound on both sides of the device. Then, under the sound absorption effect of the sound absorption groove 201, the sound inside the device is absorbed and then transmitted to the inside of the inner sound absorption chamber 204. Through the absorption of the inner sound absorption chamber 204, the transmission of sound is reduced. And under the rebound effect of the middle rebound chamber 205 on the sound, the internal and external sounds can be respectively rebound and transmitted to the inner sound absorption chamber 204 and the outer sound absorption chamber 206. Thus, under the simultaneous absorption of the inner sound absorption chamber 204 and the outer sound absorption chamber 206, the sound on both sides is isolated and absorbed, further preventing the sound from being transmitted to the other side, providing comprehensive sound insulation support inside and outside the device.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
