Summary of the Invention

[0019] In one embodiment, the support component includes a support member, and the support member has the same shape as the target noise source and is nested parallelly.

[0020] In a second aspect, an embodiment of the present application provides a method for manufacturing a noise reduction structure, including:

[0021] Manufacturing a support component and surrounding the target noise source with the support component, wherein the support component and the target noise source jointly form a noise reduction area;

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0040] The present invention will be further described below with reference to the drawings.

[0041] Household appliances are various electrical appliances used in households and similar places. They are also known as domestic appliances or household electrical appliances. Household appliances have liberated people from the cumbersome and time-consuming housework and have become necessities for family life.

[0042] Household appliances generally make noise when operating, especially large household appliances. For example, when a smart bed operates, its motor generates noise, creating an uncomfortable auditory impression for users and affecting the user experience. Currently, noise reduction is generally achieved by wrapping the noise source of household appliances with sound-absorbing materials.

[0043] However, for noise sources with specific shapes, the wrapping effect of existing sound-absorbing materials is not good, and the sound-absorbing materials need to be cut and spliced multiple times before they can be wrapped around the noise source with a specific shape, which is time-consuming, laborious, and inconvenient to install.

[0044] To solve the above technical problems, at least one embodiment of the present application provides a noise reduction structure, which includes a support component 10, a main noise reduction component 20, and a secondary noise reduction component 30; the support component 10 surrounds the target noise source 40, and the support component 10 and the target noise source 40 jointly form a noise reduction area 50; the main noise reduction component 20 is distributed in the noise reduction area 50; the secondary noise reduction component 30 is located between two adjacent main noise reduction components 20, and the secondary noise reduction component 30 is connected to the two adjacent main noise reduction components 20 to connect multiple main noise reduction components 20 into a whole; wherein, there is a gap between two adjacent main noise reduction components 20, so that the noise reduction structure can be wrapped around the target noise source 40.

[0045] As can be seen from the above, by providing a gap between two adjacent main noise reduction components 20, the gap provides a deformation space for the main noise reduction component 20 and the secondary noise reduction component 30, enabling the noise reduction structure to be directly wrapped around the target noise source 40 with a specific shape. This not only has a good wrapping effect but also is convenient for installation, thus greatly improving the installation efficiency of the noise reduction structure and solving the problem that existing sound-absorbing materials need to be cut and spliced multiple times for noise sources with specific shapes and are inconvenient to install.

[0046] As Figure 1 , Figure 2 shown, the noise reduction structure includes a support component 10, a main noise reduction component 20, and a secondary noise reduction component 30; the support component 10 surrounds the target noise source 40, and the support component 10 and the target noise source 40 jointly form a noise reduction area 50.

[0047] The main noise reduction components 20 are distributed within the noise reduction area 50. It should be noted that multiple main noise reduction components 20 can be distributed around each main noise reduction component 20, so that the noise reduction structure includes multiple layers of main noise reduction components 20, thereby improving the sound absorption and noise reduction effect. It should also be noted that the main noise reduction components 20 are elastic and can undergo elastic deformation to adapt to a target noise source 40 with a specific shape, so that the noise reduction structure can wrap and fit the noise source with a specific shape.

[0048] The auxiliary noise reduction component 30 is located between two adjacent main noise reduction components 20. The auxiliary noise reduction component 30 is connected to the two adjacent main noise reduction components 20, so that multiple main noise reduction components 20 are connected into a whole; it should be noted that two adjacent main noise reduction components 20 are connected by at least one auxiliary noise reduction component 30. It should also be noted that the auxiliary noise reduction component 30 is elastic, and the number of main noise reduction components 20 per unit volume can be increased by compressing the auxiliary noise reduction component 30, thereby improving the sound absorption and noise reduction effect; at the same time, the auxiliary noise reduction component 30 can also undergo elastic deformation to adapt to a target noise source 40 with a specific shape, so that the noise reduction structure can wrap and fit the noise source with a specific shape. By connecting the auxiliary noise reduction component 30 with the main noise reduction components 20, multiple main noise reduction components 20 are connected into a whole, which is convenient for installation and transportation.

[0049] Among them, there is a gap between two adjacent main noise reduction components 20, so that the noise reduction structure can be wrapped on the target noise source 40. The deformation performance of the noise reduction structure is improved through the gap, providing a deformation space for the main noise reduction components 20 and the auxiliary noise reduction component 30, so that the deformed noise reduction structure can wrap and fit on the noise source. The installation process can be completed without multiple cuts and splicing, which is simple and convenient.

[0050] As Figure 3 shown, in some embodiments, the main noise reduction component 20 includes a noise reduction core 210, a first noise reduction layer 220, and a second noise reduction layer 230. It should be noted that the main noise reduction component 20 can be a spherical structure. By using the spherical structure as the main noise reduction component 20, the gap between two adjacent main noise reduction components 20 can be increased to improve the applicability of the noise reduction structure.

[0051] The first noise reduction layer 220 is wrapped on the noise reduction core 210; the second noise reduction layer 230 is wrapped on the first noise reduction layer 220. The main noise reduction structure forms a multi-layer noise reduction and sound absorption structure by arranging the noise reduction core 210, the first noise reduction layer 220, and the second noise reduction layer 230 in sequence from the inside to the outside, so as to improve the sound absorption and noise reduction effect, weaken the noise of the target noise source 40, and improve the user experience.

[0052] In some embodiments, the noise reduction core 210 is made of centrifugal glass wool, and the maximum cross-sectional width of the noise reduction core 210 is 4 millimeters. It should be noted that the noise reduction core 210 can be a spherical structure. When the noise reduction core 210 is a spherical structure, the maximum cross-sectional width of the noise reduction core 210 is the diameter of the noise reduction core 210. The noise reduction core 210 made of centrifugal glass wool has a large number of interconnected pores, which can convert the sound energy of the target noise source 40 into heat, thereby achieving the effect of noise reduction and sound absorption; by limiting the maximum cross-sectional width of the noise reduction core 210, it not only avoids the too small sound absorption and noise reduction area of the noise reduction core 210, reducing the sound absorption and noise reduction effect, but also avoids the too large volume of the main noise reduction component 20, increasing the size of the noise reduction structure.

[0053] When the maximum cross-sectional width of the noise reduction core 210 is less than 4 millimeters, the sound absorption and noise reduction area of the noise reduction core 210 is small, resulting in a decrease in the sound absorption and noise reduction effect of the noise reduction structure.

[0054] When the maximum cross-sectional width of the noise reduction core 210 is greater than 4 millimeters, it will increase the volume of the main noise reduction component 20, thereby increasing the volume of the noise reduction structure. This not only brings inconvenience to the installation of the noise reduction structure, but also requires more volume to be reserved in the household appliance for installing the noise reduction structure to avoid interference between the noise reduction structure and other components of the household appliance.

[0055] In some embodiments, the first noise reduction layer 220 is made of sound-absorbing cotton, and the thickness of the first noise reduction layer 220 is 3 millimeters. The first noise reduction layer 220 made of sound-absorbing cotton has a large number of micropores, which can buffer and absorb sound waves, so that the sound waves entering the sound-absorbing cotton no longer reflect, thereby achieving the effect of sound absorption and noise reduction. At the same time, the first noise reduction layer 220 made of sound-absorbing cotton and the noise reduction core 210 made of centrifugal glass wool are three-dimensionally crossed and intertwined with each other, further enhancing the sound absorption and noise reduction effect. By limiting the thickness of the first noise reduction layer 220, it not only avoids the too thin first noise reduction layer 220, reducing the sound absorption and noise reduction effect, but also avoids the too thick first noise reduction layer 220, increasing the size of the main noise reduction component 20.

[0056] When the thickness of the first noise reduction layer 220 is less than 3 millimeters, the three-dimensionally crossed and intertwined area between the first noise reduction layer 220 and the noise reduction core 210 is small, resulting in a decrease in the sound absorption and noise reduction effect of the noise reduction structure.

[0057] When the thickness of the first noise reduction layer 220 is greater than 3 millimeters, it will increase the size of the main noise reduction component 20, thereby increasing the volume of the noise reduction structure. This not only brings inconvenience to the installation of the noise reduction structure, but also requires more volume to be reserved in the household appliance for installing the noise reduction structure to avoid interference between the noise reduction structure and other components of the household appliance.

[0058] In some embodiments, the second noise reduction layer 230 is made of latex, and the thickness of the second noise reduction layer 230 is 3 millimeters. The second noise reduction layer 230 made of latex increases the elasticity of the main noise reduction component 20. By limiting the thickness of the second noise reduction layer 230, it is possible to avoid the second noise reduction layer 230 being too thin and reducing the elasticity of the main noise reduction component 20, and also avoid the second noise reduction layer 230 being too thick and increasing the size of the main noise reduction component 20.

[0059] When the thickness of the second noise reduction layer 230 is less than 3 millimeters, the second noise reduction layer 230 does not have enough elastic deformation travel, resulting in insufficient elasticity of the main noise reduction component 20 and inconvenience in the installation of the noise reduction structure.

[0060] When the thickness of the second noise reduction layer 230 is greater than 3 millimeters, it will increase the size of the main noise reduction component 20, thereby increasing the volume of the noise reduction structure. This not only brings inconvenience to the installation of the noise reduction structure, but also requires more volume to be reserved in the household appliance for installing the noise reduction structure to avoid interference between the noise reduction structure and other components of the household appliance.

[0061] In some embodiments, the auxiliary noise reduction component 30 is made of sponge, and the maximum cross-sectional width of the auxiliary noise reduction component 30 is 15 millimeters. It should be noted that the cross-section of the auxiliary noise reduction component 30 can be square. It should also be noted that the auxiliary noise reduction component 30 can be adhered to the second noise reduction layer 230 of the main noise reduction component 20 through an adhesive. The auxiliary noise reduction component 30 made of sponge connects multiple main noise reduction components 20 into a whole, facilitating installation and transportation, and at the same time increasing the elasticity of the noise reduction structure. By limiting the maximum cross-sectional width of the auxiliary noise reduction component 30, it is possible to avoid the size of the auxiliary noise reduction component 30 being too small and affecting its elasticity, and also avoid the size of the auxiliary noise reduction component 30 being too large and reducing the sound absorption and noise reduction effect of the noise reduction structure.

[0062] When the maximum cross-sectional width of the auxiliary noise reduction component 30 is less than 15 millimeters, the auxiliary noise reduction component 30 does not have enough elastic deformation travel, and at the same time it will affect the gap between two adjacent main noise reduction components 20, resulting in a small gap and insufficient elastic deformation space for the main noise reduction component 20, thus affecting the installation of the noise reduction component.

[0063] When the maximum cross-sectional width of the auxiliary noise reduction component 30 is greater than 15 millimeters, the increase in the size of the auxiliary noise reduction component 30 will reduce the number of main noise reduction components 20 per unit volume, thereby reducing the sound absorption and noise reduction effect.

[0064] In some embodiments, the support component 10 includes a support member, and the support member and the target noise source 40 have the same shape and are nested in parallel. It should be noted that the support member includes but is not limited to a wire mesh or a plastic mesh. It should also be noted that as Figure 4As shown, the support assembly 10 further includes a plurality of reinforcing members 110. The reinforcing members 110 are disposed within the noise reduction area 50 and are connected to the support members. The reinforcing members 110 can be distributed horizontally and vertically within the noise reduction area 50, and the reinforcing members 110 play a role in improving the strength. The reinforcing members 110 include, but are not limited to, wire meshes and plastic meshes.

[0065] Through the support members nested in parallel with the target noise source 40, an installation space adapted to the target noise source 40 is provided for the main noise reduction assembly 20 and the secondary noise reduction assembly 30, solving the problem that existing sound insulation materials need to be detected and spliced by users multiple times to be adapted to the target noise source 40. At the same time, the support members can stably support the main noise reduction assembly 20 and the secondary noise reduction assembly 30, ensuring that the noise reduction structure is wrapped around the target noise source 40 with a specific shape.

[0077] Connect the secondary noise reduction component 30 to the main noise reduction component 20 by bonding.

[0078] The following specifically describes the manufacturing method of the noise reduction structure of this embodiment.
