Description

Technical Field

[0001] This application relates to the field of massagers, and more specifically, to a semi-rubber-coated massager and its manufacturing process. Background Technology

[0002] Massagers, as a common health care device, act on the body's muscle tissue through vibration, providing a comfortable massage and relieving fatigue. They are widely used in the home and personal care fields.

[0003] A massager consists of an outer casing and electronic components such as a vibrating head, motor, and power supply installed inside the casing. During the manufacturing process, the assembled electronic components are typically first coated and shaped. This coating and shaping involves first forming one half of the protective sleeve to secure the electronic component, and then forming the other half, thus creating a complete protective sleeve on the outer surface of the electronic component. Then, the surface of the electronic component covered with the protective sleeve undergoes two more processing steps to form the outer casing, ensuring that the entire electronic component is completely enclosed within it.

[0004] However, the outer casing of massagers is generally made of plastic or silicone, which requires a high molding temperature. During the molding process, prolonged exposure to high temperatures can easily affect the stability and lifespan of electronic components; moreover, the entire manufacturing process is quite complicated, making it difficult to shape the electronic components and control the shape of the resulting massager, thus reducing its performance. Summary of the Invention

[0005] To address the aforementioned technical problems—namely, the long-term high-temperature environment during the manufacturing process of massagers can easily affect the stability and lifespan of electronic components; and the entire manufacturing process is relatively cumbersome, making it difficult to shape electronic components and control the shape of the resulting massager, thereby reducing the performance of the massager—this application provides a semi-coated massager and its manufacturing process.

[0006] In a first aspect, this application provides a semi-rubber-coated massager, which includes a protective cover, an electronic component assembly, and a seal. The protective cover is provided with an installation cavity, and the cavity wall of the installation cavity has an opening. The electronic component assembly is installed in the installation cavity through the opening, and the seal is used to close the opening. The electronic component assembly includes a fixed housing and electronic components installed in the fixed housing. The outer wall of the fixed housing and the cavity wall of the installation cavity are tightly fitted together.

[0007] By adopting the above technical solution, electronic components are pre-fixed within the housing and then inserted through the opening of the mounting cavity in the protective sleeve, which is then sealed with a sealant. This semi-encased design not only simplifies the manufacturing process and reduces the impact of high temperatures during the massager's molding process, improving its stability and lifespan, but also makes the overall shape of the massager more controllable, enhancing product performance and reliability. The tight fit between the housing and the cavity wall enhances the stability of the electronic components and reduces the risk of the massager loosening due to prolonged vibration.

[0008] Preferably, the fixing shell is made of rigid plastic material, or the outer surface of the fixing shell is provided with a soft material layer.

[0009] By adopting the above technical solution, using rigid plastic materials to prepare the fixed shell can improve the structural stability of electronic components, provide better protection for electronic components, and enhance the reliability and safety of the product; by setting a soft material layer on the outer surface of the fixed shell, the good cushioning of the soft material layer can further improve the assembly and fitting stability of the protective cover, thereby improving the massage comfort of the resulting massager.

[0010] Preferably, the fixed housing consists of an upper housing and a lower housing, which are connected by screwing, plugging, snapping, or bonding.

[0011] By adopting the above technical solution, electronic components are easy to assemble and can be stably connected without loosening, thus improving the assembly stability of the fixed housing.

[0012] Preferably, the upper housing and / or the lower housing are vertically provided with a plurality of limiting blocks, and when the upper housing and the lower housing are closed, the limiting blocks abut against the surface of the assembled electronic components.

[0013] By adopting the above technical solution, the limiting block can ensure the stable fixation of electronic components in the fixed housing, avoid positional displacement caused by vibration, and improve the stability of electronic components.

[0014] Preferably, the fixed housing has a connecting part at one end near the opening of the mounting cavity, and the sealing element and the connecting part are screwed, plugged, snapped or glued together.

[0015] By adopting the above technical solution, the seal is connected to the fixed housing through the connecting part to seal the opening of the protective sleeve and improve the installation stability of the seal.

[0016] Preferably, the sealing element is any one of plastic, rubber, silicone, metal, and glass.

[0017] By adopting the above technical solutions, the sealing components have good sealing performance, and the different materials have different textures, which can improve the aesthetics of the massager.

[0018] Preferably, the protective sleeve includes a core and a body, the body being tightly bonded to the outer side of the core, the core being a non-transparent core, the body being a monochromatic translucent body, and the thickness of the outer surface of the body relative to the surface of the core being different in different regions.

[0019] By adopting the above technical solution, the sleeve body is tightly bonded to the outer surface of the sleeve core, ensuring a tight connection between the sleeve body and the sleeve core. When electronic components vibrate, the protective sleeve exhibits good structural stability and is not easily loosened. The sleeve core is made of a non-transparent material, while the sleeve body is made of a single-color translucent material. The combined effect of the sleeve core and sleeve body allows the protective sleeve to exhibit different light transmission and refraction visual effects under external light source illumination, thereby creating a gradient color and texture structure, enhancing the aesthetics and texture of the semi-encased massager.

[0020] Preferably, the outer surface of the sleeve core is provided with at least one first raised texture, and the sleeve body is provided with a first recessed texture that fits and connects with the first raised texture; and / or the outer surface of the sleeve core is provided with at least one second recessed texture, and the sleeve body is provided with a second raised texture that fits and connects with the second recessed texture, and the sleeve core is a monochrome opaque sleeve core or a multicolor opaque sleeve core.

[0021] By adopting the above technical solution, the raised and recessed textures on the outer surface of the core are respectively fitted and connected with the recessed and raised textures of the body, which improves the bonding strength between the core and the body, ensures the overall structural stability of the protective cover, and avoids the problem of the protective cover separating due to long-term vibration; at the same time, the combination of raised and recessed textures presents a uniform gradient color and texture structure, further enhancing the aesthetics and texture of the semi-rubber massager.

[0022] Secondly, this application provides a manufacturing process for a semi-rubber-coated massager, comprising the following steps:

[0023] Electronic components are assembled and fixedly installed in a fixed housing to obtain an electronic component assembly.

[0024] First molding: The first viscous silicone material is added to the cavity of the first lower mold, the core is placed in, the first upper mold and the first lower mold are closed and molded, forming a complete core sleeve on the outer surface of the core. The core and the core sleeve are detachably connected.

[0025] Second molding: Add the viscous second silicone material to the cavity of the second lower mold, put in the core with the core, close the second upper mold and the second lower mold and perform molding to form a complete sleeve on the outer surface of the core. The sleeve and the core are tightly bonded to form a protective sleeve.

[0026] Remove the core, and the protective sleeve forms an installation cavity with an opening at the position of the core. The electronic components are installed into the installation cavity through the opening. During installation, the protective sleeve undergoes elastic deformation to tightly wrap the electronic components.

[0027] The sealing element is closed over the opening to obtain a semi-rubber-coated massager;

[0028] The first silicone material is composed of silicone rubber and light-shielding filler, or the first silicone material is composed of silicone rubber, light-shielding filler and colorant; the second silicone material is composed of silicone rubber and colorant; the molding temperature is 110-160℃, and the molding time is 2-10min.

[0029] By adopting the above technical solution, the fixed shell protects the electronic components, making them easy to assemble and disassemble, and improving their stability. First, a first silicone material is used to mold a core onto the outer surface of the core, forming the initial shape of the protective sleeve. Due to the action of the light-shielding filler, the core is not translucent. If the color of the core needs to be adjusted, colorant can be added to obtain cores with different colors. Then, a second silicone material is used to form a translucent sleeve body on the outer surface of the core. With the help of the colorant, the sleeve body becomes transparent and colored. Through two molding processes, the sleeve body and core form a complete protective sleeve with good texture, elasticity, and stability. The core is then removed, and the electronic component assembly is installed in the mounting cavity of the protective sleeve. Finally, a sealing element is used to seal the opening of the mounting cavity, resulting in a semi-encapsulated massager.

[0030] This application solves the problem of traditional manufacturing processes requiring multiple molding and shaping of electronic components through a semi-coating process, without damaging the electronic components. The process is simple and easy to operate, suitable for industrial production, and the resulting semi-coated massager has good shape and performance stability.

[0031] Preferably, the silicone rubber is made from the following raw materials in parts by weight:

[0032] 50-60 parts of vinyl-terminated silicone oil

[0033] 15-25 parts vinyl MQ silicone resin

[0034] 4-8 parts of triallyl isocyanurate

[0035] 4-Vinylbenzyl glycidyl ether 4-6 parts

[0036] Vinyltris(methylisobutyl ketone oxime)silane 3-5 parts

[0037] 8-15 parts of methyl hydrosilicone oil

[0038] 2-4 parts platinum vulcanizing agent

[0039] Inhibitor 0.1-0.3 parts.

[0040] By adopting the above technical solution, the optimal amounts of triallyl isocyanurate, 4-vinylbenzyl glycidyl ether, and vinyltris(methylisobutyl ketone oxime)silane have a good synergistic effect, which can further improve the crosslinking density of vinyl silicone rubber and methyl hydrogen silicone oil, improve the flexibility and density of the prepared protective case, and the inhibitor can slow down the reaction efficiency of silicone material during the formulation process and improve the stability of silicone material. During the molding process, a protective case with stable structure and good comfort can be formed, improving the contact texture with the skin. When the protective case is assembled with electronic components, it has good elasticity and toughness, can produce stable elastic deformation, improve the assembly stability of electronic components, and is not easy to crack or deform. It can tightly wrap the electronic components, improve the tight fit between the electronic components and the protective case, and thus improve the vibration stability of the massager.

[0041] In summary, this application has the following beneficial effects:

[0042] 1. In manufacturing the semi-rubber-coated massager of this application, the electronic components are first installed in the fixed housing, then inserted into the mounting cavity of the protective sleeve, and finally sealed with a sealant. This semi-rubber-coated assembly structure simplifies the manufacturing process, reduces the impact of high temperatures on the massager during processing and molding, improves the stability and service life of the massager, and makes the overall shape of the massager more controllable, thus improving product performance and reliability. The fixed housing fits tightly against the cavity wall of the mounting cavity, improving the stability of the electronic components and reducing the problem of the massager loosening due to long-term vibration.

[0043] 2. By designing the fixed housing as an upper and lower housing, and setting limiting blocks in the upper and / or lower housing, the electronic components are stably assembled in the fixed housing and are easy to disassemble, reducing the problem of electronic components easily loosening when the massager vibrates.

[0044] 3. By setting the core to a non-transparent material and the body to a single-color translucent material, the combined effect of the raised and recessed textures of the core and body creates a protective cover that exhibits different light transmission and refraction visual effects under external light, thus forming a gradient color and texture structure that enhances the aesthetics and texture of the semi-rubber massager.

[0045] 4. The manufacturing process of this application, through two molding processes, forms a protective sleeve with good texture, elasticity and stability by combining the sleeve body and the sleeve core; then, the electronic component assembly is installed in the mounting cavity of the protective sleeve and sealed, which solves the problem of the traditional manufacturing process requiring multiple molding and shaping of electronic components, and will not damage the electronic components; the process steps are simple and easy to operate, suitable for industrial production, and the resulting semi-rubber massager has good shape and performance stability.

[0046] 5. Further optimize the material of the protective case to improve its flexibility and elasticity, so that the protective case has a comfortable texture while having good flexibility and elasticity, making it less prone to cracking and deformation, and improving assembly stability and massage comfort.

[0077] Example 1

[0078] Reference Figures 1-3 Example 1 discloses a semi-rubber-coated massager, including a protective sleeve 1, an electronic component assembly 2, and a sealing element 3. The protective sleeve 1 has an installation cavity with an opening 10 in its wall. The electronic component assembly 2 is installed within the installation cavity of the protective sleeve 1 through the opening 10. The sealing element 3 seals the opening 10. The electronic component assembly 2 includes a fixed housing 21 and electronic components 22. The electronic components 22 are installed within the fixed housing 21, and the outer wall of the fixed housing 21 is tightly fitted to the wall of the installation cavity. The fixed housing 21 is made of a rigid plastic material, or its outer surface is covered with a soft material layer. This soft material layer can be coated or covered onto the outer surface of the fixed housing 21, and can be a silicone layer, a rubber layer, or an elastomer layer. Preferably, the rigid plastic material of the fixing housing 21 is selected from materials such as ABS, PC, PP, and SEBS, and the thickness of the fixing housing 21 is 0.2-2mm, such as 0.2mm, 0.4mm, 0.5mm, 0.8mm, 1mm, 1.2mm, 1.5mm, 1.8mm, or 2mm. More preferably, in this embodiment, the rigid plastic material of the fixing housing 21 is ABS material with a thickness of 1mm, thereby making the electronic component 22 stably fixed and not easily deformed.

[0079] Reference Figures 2-3In this embodiment, the fixed housing 21 consists of an upper housing 211 and a lower housing 212. The upper housing 211 and the lower housing 212 are connected by screwing, plugging, snapping, or bonding, making the fixed housing 21 easy to assemble and improving assembly stability. The preferred connection method in this embodiment is screwing, that is, by providing corresponding screwing structures on the upper housing 211 and the lower housing 212, the upper housing 211 and the lower housing 212 are fixed by nuts or bolts. The inner sidewalls of both the upper housing 211 and the lower housing 212 are provided with several limiting blocks 213. When the upper housing 211 and the lower housing 212 are closed, the limiting blocks 213 abut against the surface of the assembled electronic components 22, limiting the movement of the electronic components 22 and preventing them from loosening during vibration. A connecting portion 23 is provided at one end of the fixed housing 21 near the opening 10 of the mounting cavity. The sealing element 3 is connected to the connecting portion 23 by means of screwing, plugging, bonding, or snap-fitting to improve the connection stability of the sealing element 3, making it less likely for the electronic component assembly 2 to fall off during vibration and improving assembly stability. Preferably, the connection method in this embodiment is screwing, which is easy to assemble and disassemble. The sealing element 3 can be any one of plastic, rubber, silicone, metal, and glass, enhancing the texture and appearance versatility of the massager.

[0080] Specific reference Figure 3 i to Figure 3 iii. The protective cover 1 includes a core 11 and a body 12. Both the core 11 and the body 12 are made of elastic materials, preferably silicone, rubber, or elastomer. In this embodiment, both the core 11 and the body 12 are made of silicone, which provides good elasticity and massage comfort. The body 12 is tightly bonded to the outer surface of the core 11. The core 11 is a non-transparent core. It should be noted that "non-transparent" here means that light cannot pass through the core 11 under natural light or strong light. The body 12 is a single-color translucent body. The single color can be one of red, orange, yellow, green, blue, purple, pink, etc. In this embodiment, the preferred color of the body 12 is pink. The thickness of the outer surface of the body 12 to the surface of the core 11 varies in different areas. By changing the thickness of the body 12 at different positions and cooperating with the non-transparent core 11, the protective cover 1 presents a gradient color and texture structure under the transmission and refraction of light, enhancing the texture and appearance diversity of the massager.

[0081] Continue to refer to Figure 3 i to Figure 3iii. Specifically, the outer surface of the sleeve core 11 is provided with at least one first raised texture 111. The first raised texture 111 can be evenly distributed or randomly distributed, and the height of the first raised texture 111 can be the same or different. Preferably, the shape of the first raised texture 111 is arc-shaped. The sleeve body 12 is recessed with a first concave texture 121 that fits and connects with the first raised texture 111. Preferably, the shape of the first concave texture 121 is also arc-shaped. The outer surface of the sleeve core 11 is recessed with at least one second concave texture 112. The second concave texture 112 can be evenly distributed or randomly distributed, and the height of the second concave texture 112 can be the same or different. Preferably, the shape of the second concave texture 112 is arc-shaped. The sleeve body 12 is provided with a second raised texture 122 that fits and connects with the second concave texture 112. The shape of the second raised texture 122 is also arc-shaped. The sleeve core 11 is a monochrome opaque sleeve core or a multi-color opaque sleeve core. Preferably, the sleeve core 11 in this embodiment is a monochrome opaque sleeve core. By setting concave and convex textures, the core 11 and the body 12 can be stably connected, and the resulting protective sleeve 1 has good stability, elasticity and diverse appearance.

[0082] Example 2

[0083] Example 2 discloses the manufacturing process of the semi-rubber-coated massager of Example 1, including the following steps:

[0084] Electronic components are assembled and fixedly installed in a fixed housing to obtain an electronic component assembly.

[0085] Reference Figure 4 First molding: Using a molding vulcanizing machine, the viscous first silicone material is added to the cavity of the first lower mold, the core is placed in, the first upper mold and the first lower mold are closed and molding is performed, wherein the molding temperature is controlled at 110℃ and the time is 2 minutes, forming a complete core sleeve on the outer surface of the core, and the core and the core sleeve can be detachably connected.

[0086] Reference Figure 5 Second molding: Using a molding vulcanizing machine, add the viscous second silicone material into the cavity of the second lower mold, place the core with the core in it, close the second upper mold and the second lower mold and perform molding. Control the molding temperature to 160℃ and the time to 10 minutes. A complete sleeve is formed on the outer surface of the core. The sleeve and the core are tightly bonded to form a protective sleeve.

[0087] Remove the core, and the sleeve core of the protective sleeve forms an installation cavity with an opening corresponding to the core. The electronic components are installed into the installation cavity through the opening. During installation, the protective sleeve undergoes elastic deformation to tightly wrap the electronic components.

[0088] The sealing element is placed over the opening to produce a semi-rubber-coated massager.

[0089] The first silicone material consists of silicone rubber and light-shielding filler in a weight ratio of 4:1. The light-shielding filler consists of titanium dioxide and fumed silica in a weight ratio of 2:1. The titanium dioxide has a particle size of 50-75 nm, and the fumed silica has a particle size of 100-150 nm. To prepare a colored core, 1% of the silicone rubber weight of the colorant can be added. The second silicone material consists of silicone rubber and 1% of the silicone rubber weight of the colorant. In this embodiment, a commercially available silicone colorant is used, and the type is not limited.

[0090] It should be noted that the amount of the first and second silicone materials in this embodiment is not limited and can be adjusted according to the size and thickness of the core and the body to fill the cavity during the molding process and form a complete core and body.

[0091] In this embodiment, the silicone rubber used in the first and second silicone materials is made from 6 kg of ethylene-terminated silicone oil, 2 kg of vinyl MQ silicone resin, 0.8 kg of methyl hydrogen silicone oil, 0.2 kg of platinum vulcanizing agent, and 0.01 kg of acetylene cyclohexanol.

[0092] Examples 3-4

[0093] The difference between Examples 3-4 and Example 2 lies in the different preparation process parameters, as detailed in Table 2 below.

[0094] Table 2. Process parameters for Examples 2-4

[0095]

[0096] Examples 5-11

[0097] The difference between Examples 5-11 and Example 2 is that the source of the silicone rubber is different, as detailed in Table 3 below.

[0098] Table 3. Source of silicone rubber in Examples 5-11

[0099]

[0100] 1. Mechanical property testing:

[0101] The first silicone material from Examples 2-11 was vulcanized at 120°C for 10 minutes to obtain a test piece. Following the test method in GB / T 528-2009, the test piece was cut into type A standard ring-shaped specimens.

[0102] 1) Test the tensile strength at break of the type A standard ring specimen (unit: MPa);

[0103] 2) Perform a tensile test on the type A standard ring specimen. Stretch the specimen until the elongation of the type A standard ring specimen is 250%. Let it stand for 10 seconds, then cancel the stretching. After the test strip recovers for 30 seconds, repeat the stretching 10 times. Detect the deformation rate of the test strip (unit: %). Deformation rate = (inner diameter after test - inner diameter before test) / inner diameter before test * 100%. Test and record the test results.

[0104] 3. Assembly performance test:

[0105] Assemble the fixed housing along the opening of the protective sleeve. The size of the protective sleeve is the same as that of the fixed housing. Repeat the assembly process 3 times. Visually inspect the opening of the protective sleeve for signs of breakage or whitening. Test and record the results.

[0106] The following are the performance test data of the semi-rubber massagers in Examples 2-11, as detailed in Table 4 below.

[0107] Table 4 Performance test data of the semi-rubber-coated massagers in Examples 2-11

[0108]

[0109] Based on Examples 2-4 and 5-7, and referring to Table 4, it can be concluded that the silicone rubber preparation of the first and second silicone materials in this application, used to fabricate the core and body of the sleeve, results in a protective sleeve with good assembly stability, flexibility, and elasticity. It is less prone to deformation during assembly, can stably adhere to electronic components, and reduces loosening caused by vibration. Compared to Example 2, Examples 5-7 show an increase in elongation at break of 17.7 MPa and a decrease in deformation rate of 9.4%.

[0110] Based on Examples 5-7 and 8-11, and in conjunction with Table 4, it can be concluded that the triallyl isocyanurate, 4-vinylbenzyl glycidyl ether, and vinyltris(methylisobutyl ketone oxime)silane of this application have a synergistic effect, which can further increase the crosslinking density of vinyl silicone rubber and methyl hydrogen silicone oil, improve the flexibility and elasticity of the prepared protective case, making the protective case less prone to whitening, cracking, and deformation. Compared with Example 2, Examples 8-11 did not use triallyl isocyanurate, 4-vinylbenzyl glycidyl ether, and vinyltris(methylisobutyl ketone oxime)silane for formulation, resulting in a decrease in tensile strength at break and an increase in deformation rate.

[0111] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
