[0001] The utility model belongs to the field of beds and accessories thereof, in particular to a noise reduction controller and a bed. Background Art

[0002] Existing smart beds are equipped with an air mattress and a controller connected to the air mattress. The controller controls the inflation and deflation of the air mattress to achieve massage and relaxation effects, thereby promoting sleep. The controller is usually set on the bed frame and produces a loud noise when working. Users usually fall asleep after massage. If the controller produces a loud noise, it will affect the user experience and even affect the sleep of light sleepers. Therefore, it is necessary to improve the controller structure to reduce the impact of noise. Utility Model Content

[0005] The inner shell and the inner shell cover enclose the controller body, and the porous structure on the inner shell converts sound waves into heat energy to consume noise, thereby playing a noise reduction role. The noise reduction effect is relatively ideal, and the suspension is connected to the inner shell cover. During assembly, it is sufficient to ensure that the inner shell and the inner shell cover are matched, which makes assembly easy. In addition, the entire noise reduction controller has a compact structure and a reasonable layout.

[0006] Furthermore, the inner shell cover has a porous structure to further enhance the noise reduction effect.

[0007] Furthermore, the housing further includes an outer housing disposed outside the inner housing, with a first noise reduction layer disposed between the outer housing and the inner housing. The first noise reduction layer disposed between the outer housing and the inner housing acts as a noise reduction barrier, reducing the noise propagation path and further attenuating the impact of the noise.

[0008] Furthermore, the outer shell is provided with a first support column, and the inner shell is connected to the outer shell via screws mounted on the first support column. The first support column forms a first gap between the outer shell and the inner shell, and the first noise reduction layer is disposed in the first gap. The inner shell and the outer shell are connected via screws, and the first noise reduction layer fills the first gap, not only providing a noise reduction effect, but also ensuring that the outer shell and inner shell are connected as a whole, effectively preventing collisions between the inner shell and the outer shell due to loose screws.

[0009] Furthermore, an upper cover is provided on the top of the outer shell, and a second noise reduction layer is provided between the upper cover and the inner shell. In this arrangement, the second noise reduction layer acts as a noise reduction barrier, which can reduce the noise propagation path and further reduce the impact of noise.

[0010] Furthermore, the upper cover is provided with a second support column, and the inner shell is connected to the upper cover via screws provided on the second support column. The second support column forms a second gap between the upper cover and the inner shell, and the second noise reduction layer is provided in the second gap.

[0012] Furthermore, the first noise reduction layer has a double-layer structure, comprising a connected butyl rubber layer and a polyester fiber cotton layer, wherein the polyester fiber cotton layer is located on the inner side. After the noise is reduced by the inner shell, the sound passes through the polyester fiber cotton layer and is absorbed by the polyester fiber cotton layer, further reducing the noise. The butyl rubber layer also has a sound insulation effect, further ensuring the noise reduction effect.

[0013] Furthermore, the second noise reduction layer is a double-layer structure, comprising a connected butyl rubber layer and a polyester fiber cotton layer, wherein the polyester fiber cotton layer is located on the inner side. After the noise is reduced by the porous inner shell, the sound passes through the polyester fiber cotton layer and is absorbed by the polyester fiber cotton layer, further reducing the noise. The butyl rubber layer also provides a sound insulation effect, further ensuring the noise reduction effect.

[0014] The present application also provides a bed comprising an air mattress, a bed frame, and a controller, wherein the controller is disposed at the bottom of the bed frame and is used to control the inflation and deflation of the air mattress. The controller is the aforementioned noise reduction controller. A bed using this noise reduction controller is quieter and provides a better user experience.

[0015] The utility model has the following beneficial effects: the present application provides a noise reduction controller and bed, wherein the inner shell and inner shell cover enclose the controller body. The porous structure of the inner shell converts sound waves into heat energy, thereby consuming noise and achieving a relatively good noise reduction effect.

DETAILED DESCRIPTION

[0024] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the accompanying drawings of the present invention. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0025] Example 1

[0026] A noise reduction controller, such as Figures 1 to 6As shown, it includes a controller body 1 and a shell, the controller body 1 includes a suspension 11 and an air pump assembly 12 and a solenoid valve assembly 13 arranged on the suspension 11, wherein the air pump assembly 12 is used to generate airflow, and the solenoid valve assembly 13 is used to control the airflow interruption, the shell includes an inner shell 2 for accommodating the controller body 1, an inner shell cover 3 is provided on the top of the inner shell 2, the suspension 11 is connected to the inner shell cover 3, and the inner shell 2 has a porous structure.

[0027] The inner shell 2 and the inner shell cover 3 enclose the controller body 1, and the porous structure on the inner shell 2 converts sound waves into heat energy to consume noise, thereby playing a noise reduction role. The noise reduction effect is relatively ideal, and the suspension 11 is connected to the inner shell cover 3. During assembly, it is sufficient to ensure that the inner shell 2 and the inner shell cover 3 are matched, which makes assembly easy. In addition, the entire noise reduction controller has a compact structure and a reasonable layout.

[0028] The setting principle is as follows: the inner shell 2 and the inner shell cover 3 form a cavity, and the controller body 1 (sound source component) is placed in the cavity; when sound passes through the inner shell 2 with a porous structure, the sound waves can enter the interior of the inner shell 2 along the micropores, causing the air in the gap to vibrate. Due to the viscous resistance of the air, the friction between the air and the hole wall, and the heat conduction effect, a considerable part of the sound energy is converted into heat energy and is lost, thereby achieving the purpose of sound absorption.

[0029] The inner shell cover 3 has a porous structure and still adopts the above-mentioned noise reduction principle, so that the sound waves are consumed, further enhancing the noise reduction effect.

[0030] The housing further includes an outer housing 4 disposed outside the inner housing 2, with a first noise reduction layer 5 disposed between the outer housing 4 and the inner housing 2. The first noise reduction layer 5 disposed between the outer housing 4 and the inner housing 2 acts as a noise reduction barrier, reducing the noise propagation path and further attenuating the impact of the noise.

[0031] The outer shell 4 is provided with a first support column 41. The inner shell 2 is connected to the outer shell 4 via screws C mounted on the first support column 41. The first support column 41 forms a first gap between the outer shell 4 and the inner shell 2. The first noise reduction layer 5 is disposed in this first gap. The inner shell 2 and the outer shell 4 are connected via screws C. The first noise reduction layer 5 fills the first gap, not only providing noise reduction but also ensuring that the outer shell 4 and the inner shell 2 are connected as a whole, effectively preventing collisions between the inner shell 2 and the outer shell 4 due to loose screws C.

[0032] An upper cover 6 is provided on the top of the outer shell 4, and a second noise reduction layer 7 is provided between the upper cover 6 and the inner shell 3. In this arrangement, the second noise reduction layer 7 acts as a noise reduction barrier, which can reduce the noise propagation path and further reduce the impact of the noise.

[0033] The upper cover 6 is provided with a second support column 61. The inner shell 3 is connected to the upper cover 6 via screws C mounted on the second support column 61. The second support column 61 forms a second gap between the upper cover 6 and the inner shell 3. The second noise reduction layer 7 is positioned in this second gap. The upper cover 6 and the inner shell 3 are connected via screws C. The second noise reduction layer 7 fills the second gap, providing effective noise reduction and integrating the upper cover 6 and the inner shell 3.

[0034] The upper cover 6 and the outer shell 4 are fastened together by snaps, and the inner shell cover 3 and the inner shell 2 are fastened together by snaps. This structure facilitates the assembly of the upper cover 6 and the outer shell 4, and the inner shell cover 3 and the inner shell 2, and the assembly can be completed by simply pressing down to engage the corresponding parts.

[0035] The first noise reduction layer 5 has a double-layer structure, comprising a connected butyl rubber layer A and a polyester fiber layer B, with the polyester fiber layer B located on the inner side. After being reduced by the inner shell 2, the sound passes through and is absorbed by the polyester fiber layer B, further reducing the noise. The butyl rubber layer A provides a soundproofing effect, further enhancing the noise reduction effect.

[0036] The second noise-reduction layer 7 has a double-layer structure, comprising a connected butyl rubber layer A and a polyester fiber layer B, with the polyester fiber layer B located on the inner side. After being reduced by the porous inner shell 3, the sound passes through and is absorbed by the polyester fiber layer B, further reducing the noise. The butyl rubber layer A also provides sound insulation, further enhancing the noise reduction effect.
