Description

Technical Field

[0001] The invention belongs to the technical field of atomization, and in particular relates to a noise reduction atomization device. Background Art

[0002] Suction noise is one of the important evaluation dimensions of atomizers. In related technologies, various structural components within the atomizer form an airway with a complex shape. Suction noise is generated when the suction airflow passes through various dislocated, corner or small-aperture airways. Excessive suction noise will affect the user's experience and comfort. The market generally requires that the suction noise of the atomizer during suction must be lower than 45 decibels.

[0003] At present, some noise reduction solutions adopt the solution of adding sound insulation cotton to the structural shells of the atomizer device or installing a silencer at the airway suction inlet to reduce noise, but this solution is not suitable for ultra-thin, delicate and compact small atomizer devices. Due to limited space, it is difficult for small atomizer devices to place sound insulation and noise reduction devices such as sound insulation cotton. The noise reduction function can only be achieved by optimizing the original materials or structures of the atomizer device. However, the wall material thickness of the shell or structural parts of the atomizer device is often at the millimeter level. It is extremely difficult to process the noise reduction structure of the millimeter-level wall material, and it is difficult to ensure that the atomizer device has sufficient structural strength and good noise reduction effect at the same time. Summary of the Invention

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] Example: See also Figures 1 to 5 This embodiment provides a noise reduction atomizer device, which includes a housing having a first end and a second end. An air passage 10 extends from the first end of the housing into the housing. The housing contains an atomizing liquid and an atomizing core. The atomizing core can heat the atomizing liquid to generate an aerosol when in operation. The air passage 10 transports the aerosol to an outlet at the first end of the housing. At least part of the wall material of the shell and / or air duct 10 is noise reduction wall material 100; the thickness of the noise reduction wall material 100 is less than 5 mm; the noise reduction wall material 100 includes a first layer 110 and a second layer 120 arranged on the outside of the first layer 110, and the first layer 110 and the second layer 120 are arranged at intervals to form an intermediate layer 130 between the first layer 110 and the second layer 120, and a support member 140 is provided in the intermediate layer 130 to abut against the first layer 110 and the second layer 120, and the support member 140 forms a diffuse reflection structure for diffusely reflecting sound waves.

[0023] The support member 140 is used to diffusely reflect the noise passing through the middle layer 130. When the sound waves of the noise enter the middle layer 130, the sound waves will continuously hit the support member 140 with a diffuse reflection structure in the middle layer 130, so that the mechanical energy of the sound waves is gradually consumed, thereby achieving noise reduction.

[0024] When the atomizing device is in use, the suction airflow will generate noise through the air passage 10 of the atomizing device. Figure 3 As shown, the suction noise is reduced by at least partially using noise reduction wall materials on the housing and / or air duct 10 of the atomizing device, wherein the first layer 110, the second layer 120 and the middle layer 130 of the millimeter-level noise reduction wall materials form a sandwich structure, and a support member 140 is provided in the middle layer 130 to abut against the first layer 110 and the second layer 120. The support member 140 has a diffuse reflection structure, which achieves a good noise reduction effect while ensuring the structural strength of the noise reduction wall material. In addition, as part of the housing or the air duct 10 wall material of the atomizing assembly, the noise reduction wall material 100 occupies a small volume and has a simple structure. There is no need to install sound insulation cotton or other sound insulation and noise reduction devices at other locations of the atomizing device, which is beneficial to reducing the suction noise of small atomizing devices.

[0025] It should be known that the noise reduction wall material 100 in the present invention is used as the wall material of the shell or structural parts of a small atomizing device, which is beneficial to the noise reduction of the small atomizing device, but the noise reduction wall material 100 is not limited to application in small atomizing devices. The noise reduction wall material 100 is suitable for atomizing devices of various sizes and can also be combined with other noise reduction structures of the atomizing device. For example, the noise reduction wall material 100 of the present invention can also be used as the wall material of the noise reduction resonant cavity, or combined with various noise reduction structures such as silencer cotton and porous materials to jointly reduce the suction noise of the atomizing device. In addition, the intermediate layer formed between the first layer and the second layer can be fully sealed or partially sealed according to different situations.

[0026] Furthermore, a plurality of hollow cylindrical and / or spherical materials are evenly distributed in the middle layer 130 to form at least one filling layer, and the first layer 110 and the second layer 120 are supported by the filling layer.

[0027] like Figure 4 (b) and Figure 5 As shown in (b), Figure 4 (b) is a partial schematic diagram of the noise reduction wall material 100 in one embodiment. Figure 5 (b) Yes Figure 4 (b) is a schematic diagram of the noise reduction wall material 100 from another perspective. As an example, the middle layer 130 is filled with hollow cylindrical materials. Multiple hollow cylindrical materials form a diffusely reflective support member 140 in the middle layer 130. The sound waves of the suction noise can continuously reflect on the surface of each cylindrical material to consume energy.

[0028] In addition, since the thickness of the noise reduction wall material 100 is less than 5 mm, too thin first layer 110 and second layer 120 will lead to insufficient overall structural strength. The first layer 110 and second layer 120 require a certain thickness to ensure the overall structural strength. Filling the middle layer 130 of the noise reduction wall material 100 with hollow cylindrical and / or spherical materials can not only reduce noise, but also support the first layer 110 and second layer 120, while having the effects of improving strength and sound insulation and noise reduction.

[0029] It should be understood that hollow cylindrical and / or spherical materials can be prepared using a variety of materials such as high molecular polymers, inorganic non-metallic compounds, and composite materials. Hollow cylindrical and spherical materials have mature preparation processes, are low-cost, and can be purchased in large quantities, making them a preferred solution for forming the support member 140. Preferably, the hollow portion of the hollow spherical material can also be in a vacuum state, thereby further improving the noise reduction capability of the noise reduction wall material 100 by reducing the propagation medium of the sound waves of the suction noise. The middle layer 130 can also be filled with polyhedral hollow materials or solid porous particles or other fillers that are conducive to forming the support member 140, and the middle layer 130 can also be evacuated to form a vacuum state.

[0030] Hollow cylindrical materials can be Figure 4 The evenly spaced distribution shown in (b) can also be closely arranged. If the hollow cylindrical materials are evenly spaced, the hollow cylindrical materials need to be fixedly connected to the inner wall of the first layer 110 and / or the second layer 120 during the production process.

[0031] Furthermore, if Figure 4 (b) and Figure 5 As shown in (b), a plurality of hollow cylindrical and / or spherical materials are evenly distributed in the middle layer 130 to form at least one filling layer, and the first layer 110 and the second layer are supported by the filling layer.

[0032] As an example, a hollow cylindrical material is evenly distributed within middle layer 130 to form a filling layer. The thickness of middle layer 130 is equal to the outer diameter of the circular cross-section of the hollow cylindrical material perpendicular to the axis. The hollow cylindrical material is fixed between first layer 110 and second layer 120 to support the first and second layers 110, 120, thereby increasing the structural strength of noise reduction wall material 100.

[0033] In other embodiments, the hollow cylindrical material may be evenly stacked to form multiple filling layers, and the thickness of the middle layer 130 is greater than or equal to the outer diameter of the circular cross section of the hollow cylindrical material perpendicular to the axis.

[0034] As another example, a layer of hollow spherical material is evenly distributed within the middle layer 130 to form a filling layer, and the thickness of the middle layer 130 is equal to the particle size of the hollow spherical material. The hollow spherical material is fixed between the first layer 110 and the second layer 120 to support the first layer 110 and the second layer 120, and also serves to increase the structural strength of the noise reduction wall material 100.

[0035] In other embodiments, the hollow spherical materials may be evenly stacked to form multiple filling layers, and the thickness of the middle layer 130 is greater than or equal to the particle size of the hollow spherical materials.

[0036] Furthermore, if Figure 4 As shown in (b), the hollow cylindrical and / or spherical materials are hollow microbeads, and the material of the hollow microbeads is an inorganic non-metallic material.

[0037] Hollow microspheres, also known as hollow microbeads, are a new type of inorganic non-metallic material with excellent performance in the form of a hollow spherical powder. Their particle size typically ranges from 0.04 to 0.125 mm, and their wall thickness typically ranges from 1 to 2 μm. Hollow microspheres are manufactured using a mature process and are relatively low-cost. They are commonly used as fillers in coatings, thermosetting plastics, adhesives, and fiberglass reinforced plastics. Filling these products with the hollow microsphere structure can reduce costs and provide thermal insulation.

[0038] Hollow microspheres are lightweight and have high compressive strength. When used in the noise reduction wall material 100 of the present invention, they not only provide sound insulation and noise reduction, but also support the first layer 110 and the second layer 120, thereby increasing the strength of the noise reduction wall material 100. Furthermore, compared to ordinary wall materials or wall materials made of noise reduction wall materials 100 in which the middle layer 130 is filled with solid support members 140, the wall material made of noise reduction wall materials 100 filled with hollow microspheres is lighter, providing a better user experience. Furthermore, hollow microspheres are low-cost and can be directly filled into the middle layer 130 during the preparation process without the need for additional complex processing, which is a significant advantage.

[0039] Furthermore, if Figure 4 (c) and Figure 5 As shown in (c), the support member 140 includes a plurality of curved surface layers, the cross-sectional shape of the curved surface layers along the thickness direction of the intermediate layer 130 is serrated, concave-convex and / or corrugated, and the curved surface layers fill the intermediate layer 130 .

[0040] The cross-sectional shape of the intermediate layer 130 along the thickness direction is a serrated, concave-convex and / or corrugated curved layer, which can make the sound waves of the suction noise reflect between the multiple curved surfaces of the curved layer, gradually consuming the mechanical energy of the sound waves and converting it into heat energy, thereby achieving the effect of reducing noise.

[0041] Specifically, as an example, according to the shape of the wall material of a certain part of the atomizing device to be prepared, the mold is processed by surface etching or wire cutting method, so that the first layer 110, the second layer 120 and the curved layer are separately formed by the mold, and then the first layer 110, the curved layer and the second layer 120 are assembled and the edges of the first layer 110 and the second layer 120 are sealed to obtain the wall material of the atomizing device with noise reduction wall material 100.

[0042] In other embodiments, the surface of the curved layer to be processed may be directly processed, and the cross section of the curved layer to be processed along the thickness direction may be processed into a serrated, concave-convex and / or corrugated shape by cutting or other means.

[0043] Furthermore, two surfaces of the curved layer along the thickness direction are at least partially in contact with or fixedly connected to the first layer 110 and the second layer 120 .

[0044] The two sides of the curved layer are at least partially abutted or fixedly connected to the first layer 110 and the second layer 120, which effectively reduces the volume of the cavity of the middle layer 130, improves the strength of the noise reduction wall material 100, and takes into account the noise reduction effect and strength reliability of the atomization device using the noise reduction wall material 100.

[0045] In one embodiment, if Figure 5As shown in (c), the cross-sectional shape along the thickness direction of the intermediate layer 130 is a sawtooth-shaped curved surface layer, the tooth height of each sawtooth is equal and slightly smaller than the thickness of the intermediate layer 130, and the tooth width is equal. The tooth tip of each sawtooth on one side of the sawtooth-shaped curved surface layer is fixedly connected to the second layer 120.

[0046] In other embodiments, the cross-sectional shape along the thickness direction of the intermediate layer 130 is a corrugated curved surface layer, so that the multiple wavelengths of the corrugated cross-section are equal, the multiple wave heights are equal and equal to the thickness of the intermediate layer 130, so that each wave top and wave bottom are in contact with or fixed to the first layer 110 and the second layer 120, so as to better achieve the effect of supporting the first layer 110 and the second layer 120. The serrated or concave-convex curved surface layer can also have the same design as the corrugated curved surface layer.

[0047] Furthermore, the material of the curved surface layer is any one of metal, glass, plastic or ceramic.

[0048] Specifically, various materials can be prepared to form a curved surface layer through various methods such as injection molding, surface etching or wire cutting. Relevant technicians are familiar with the corresponding preparation methods when manufacturing different structural parts or shell wall materials of the atomization device, which will not be repeated here.

[0049] Furthermore, the surface of the first layer 110 facing the second layer 120 has a plurality of grooves and / or protrusions. And / or, the surface of the second layer 120 facing the first layer 110 has a plurality of grooves and / or protrusions.

[0050] In some embodiments, the facing surfaces of the first layer 110 and the second layer 120 can be smooth; in other embodiments, the facing surfaces of the first layer 110 and the second layer 120 can have a concave-convex structure. The facing surfaces of the first layer 110 and the second layer 120 can be provided with multiple grooves and / or protrusions simultaneously, or only on the first layer 110 or the second layer 120. The first layer 110 can have both multiple grooves and multiple protrusions on the surface facing the second layer 120, or only on either one. The second layer 120 can also have the same configuration. Specifically, the grooves can be strip-shaped or dot-shaped grooves, and the protrusions can be strip-shaped or dot-shaped protrusions. Depending on the materials of the first layer 110 and the second layer 120, millimeter-scale protrusions or depressions can be machined onto the surfaces of the first layer 110 and the second layer 120 through processes such as CNC machining, laser cutting, electrical discharge machining, and chemical etching.

[0051] Such an arrangement enables the first layer 110 and the second layer 120 to form a synergistic noise reduction effect with the support member 140 having a diffuse reflection structure, thereby improving the noise reduction capability of the noise reduction wall material 100 .

[0052] Further, if Figure 4As shown in the partial schematic diagrams of the noise reduction wall material 100 in (a), (b) and (c), the middle layer 130 is in a vacuum state.

[0053] Preferably, when a support member 140 is provided in the middle layer 130, an exhaust gap connecting the middle layer 130 is reserved when the edges of the first layer 110 and the second layer 120 are sealed so that the middle layer 130 is in a vacuum state, and the gas in the middle layer 130 is evacuated through the exhaust gap and the exhaust gap is sealed to form an middle layer 130 in a vacuum state.

[0054] On the one hand, the energy of the sound waves of the suction noise is consumed by the first layer 110, the second layer 120 and the support member 140 in the middle layer 130, thereby achieving the effect of reducing the suction noise. On the other hand, the medium air for the propagation of the sound waves in the middle layer 130 is removed, and the suction noise is reduced by cutting off the propagation path of the noise waves, thereby improving the comfort of the user's suction experience.

[0055] Furthermore, the non-edge portions of the first layer 110 and the second layer 120 are partially connected, so that the middle layer 130 between the first layer 110 and the second layer 120 is separated to form a plurality of cavities, and the support member 140 is disposed in each cavity.

[0056] For example, the cavity can be an annular cavity extending along a cross-sectional trajectory of the noise reduction wall material 100 perpendicular to the axial direction of the atomizing device. The cavities can be spaced apart along the axial direction of the atomizing device. The cavity can also be a strip, square, circular, or other shape that can ensure that the support member 140 can be placed in the cavity. The cavities can be connected or completely sealed.

[0057] The non-edge portions of the first layer 110 and the second layer 120 are partially connected, separating the middle layer 130 to form a plurality of cavities, thereby further improving the structural strength of the noise reduction wall material 100 .

[0058] Furthermore, the cavities are distributed in a uniform array or in a staggered array on the noise reduction wall material 100 .

[0059] The uniform array distribution or staggered array distribution of the cavities can evenly disperse the external stress borne by the noise reduction wall material 100 and improve the structural strength of the noise reduction wall material 100.

[0060] Furthermore, the thickness of the noise reduction wall material 100 is 0.7-4 mm; the thickness of the first layer 110 and the second layer 120 are 0.3-3 mm, respectively; and the thickness of the intermediate layer 130 is greater than or equal to 0.1 mm. This configuration not only meets the lightweight and miniaturized requirements of the noise reduction wall material 100 as the wall material of the atomization device, but also ensures the basic structural strength of the wall material by filling the intermediate layer 130 with support members 140.

[0061] Furthermore, the material of the first layer 110 and the second layer 120 is any one of metal, glass, plastic or ceramic. Specifically, depending on the different materials used, the first layer 110 and the second layer 120 can be formed once to seal the edges, or can be formed multiple times.

[0062] Test Case Specifically, the wall material of the control example and the noise reduction wall material 100 of schemes A, B and C described below are used as wall materials on the air pipe and the shell of the atomizing device. The specific settings of each scheme are as follows: Comparative example: Figure 1 As shown, the noise reduction wall material 100 is applied to the air duct 10 of the atomizing device with the same structure, wherein the air duct 10 of the atomizing device of the control example uses a single-layer solid wall material, the material of the solid wall material is polycarbonate (PC), and the thickness of the solid wall material is 0.5 mm.

[0063] Test Example 1: Solution A uses the noise reduction wall material 100 as the wall material of the air duct 10. Specifically, the noise reduction wall material 100 in Solution A is as follows: Figure 4 As shown in (a), it includes a first layer 110 and a second layer 120 spaced apart on the outside of the first layer 110 . The edges of the first layer 110 and the second layer 120 are sealed to form a sealed middle layer 130 , and the middle layer 130 is in a vacuum state.

[0064] The air duct 10 and the shell of the atomizing device of Test Example 1 use the noise reduction wall material 100 of Solution A as a whole. The material of the noise reduction wall material 100 is polycarbonate (PC). The thickness of the first layer 110 and the second layer 120 are both 0.2 mm, and the thickness of the middle layer 130 is 0.1 mm. The total thickness is equal to the thickness of the solid wall material of the control example, and the diameter of the air outlet is 2 mm.

[0065] Test Example 2: Solution B uses the noise reduction wall material 100 as the wall material of the air duct 10. Specifically, the noise reduction wall material 100 in Solution B is as follows: Figure 4 As shown in (b), it includes a first layer 110 and a second layer 120 spaced apart on the outside of the first layer 110, the edges of the first layer 110 and the second layer 120 are sealed, and a support member 140 is provided in the sealed middle layer 130 between the first layer 110 and the second layer 120, wherein the middle layer 130 is filled with a hollow cylindrical material to form the support member 140.

[0066] The air duct 10 and the shell of the atomizing device of Test Example 2 are made of the wall material of Solution B. The noise reduction wall material 100 is made of polycarbonate (PC). The thickness of the first layer 110 and the second layer 120 are both 0.2 mm, and the thickness of the middle layer 130 is 0.1 mm. The total thickness is equal to the thickness of the solid wall material of the control example. The middle layer 130 is filled with hollow glass microspheres with a particle size of 0.1 mm, and the air outlet diameter is 2 mm.

[0067] Test Example 3: Solution C uses the noise reduction wall material 100 as the wall material of the air duct 10. Specifically, the noise reduction wall material 100 in Solution C is as follows: Figure 5 As shown in (c), it includes a first layer 110 and a second layer 120 spaced apart on the outside of the first layer 110, the edges of the first layer 110 and the second layer 120 are sealed and connected, and a support member 140 is provided in the sealed intermediate layer 130 between the first layer 110 and the second layer 120, wherein a curved surface layer having a serrated cross-sectional shape along the thickness direction of the intermediate layer 130 is provided in the intermediate layer 130 to form the support member 140.

[0068] The air passage 10 and housing of the atomizer of Test Example 3 used the wall material of Scheme C. The noise reduction wall material 100 was made of polycarbonate (PC). The thickness of the first layer 110 and the second layer 120 were both 0.2 mm, and the thickness of the middle layer 130 was 0.1 mm. The total thickness was equal to that of the solid wall material of the control example. The middle layer 130 was filled with a serrated curved layer of polycarbonate (PC), and the diameter of the air outlet was 2 mm. The atomizer devices of the control example, test example 1, test example 2, and test example 3 are now subjected to a suction noise test. The test method is as follows: a closed soundproof box is set up in a test room with a noise level lower than 40 dB, and a decibel meter and a suction device are set up in the soundproof box. The air inlet of the air duct 10 of the atomizer device in the control example and each test is connected to the suction device. Under the condition that the air flow rate through the air outlet is 6 ml / s, the decibel meter is started to test the sound intensity of the suction noise. The test results are shown in Table 1.

[0069] As can be seen, in Test Example 1, the middle layer 130 of the noise reduction wall material 100 is not provided with support members 140. The middle layer 130 is vacuum-set. Although it is difficult to meet the structural strength requirements of the atomization device, it can reduce noise by about 20% compared to the control example, proving that the vacuum setting of the middle layer can significantly reduce suction noise. Test Examples 2 and 3 can reduce noise by up to about 17% compared to the control example, showing a significant effect in reducing suction noise, demonstrating that the use of the noise reduction wall material 100 as the wall material of the air duct 10 is effective in reducing suction noise.

[0070]

[0071] Table 1 The noise reduction wall material and atomization device provided by the present invention have obvious advantages. The wall material made of the noise reduction wall material is light and thin, has sufficient strength and good noise reduction effect, and has low preparation cost.
