Description

A semi-rubber-coated massager and its manufacturing process 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: Assembling and fixing electronic components within a fixed housing to obtain an electronic component assembly; First molding: Adding a viscous first silicone material to the cavity of a first lower mold, placing a core inside, closing the first upper mold and the first lower mold, and molding to form a complete sleeve core on the outer surface of the core, wherein the core and the sleeve core are detachably connected; Second molding: Adding a viscous second silicone material to the cavity of a second lower mold, placing a sleeve core with a core inside, closing the second upper mold and the second lower mold, and molding to form a complete sleeve body on the outer surface of the sleeve core, wherein the sleeve body and the sleeve core are tightly bonded to form a protective sleeve; Removing the core, the protective sleeve forming an installation cavity with an opening corresponding to the core position, installing the electronic component assembly into the installation cavity through the opening, wherein the protective sleeve undergoes elastic deformation during installation to tightly wrap the electronic component assembly; Covering the opening with a sealing element to obtain a semi-rubber-coated massager; 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.

[0023] 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.

[0024] 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.

[0025] Preferably, the silicone rubber is made from the following raw materials in parts by weight:

[0026] 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 cover, 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 cover with stable structure and good comfort can be formed, improving the contact texture with the skin. When the electronic components are assembled, the protective cover 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 cover, and thus improve the vibration stability of the massager.

[0027] In summary, this application has the following beneficial effects: 1. In the preparation of the semi-rubberized 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 sealing element. This semi-rubberized assembly structure simplifies the manufacturing process, reduces the problem of the massager being affected by high temperatures during processing and molding, improves the stability and service life of the massager, and makes the overall shape of the massager more controllable, improving the performance and reliability of the product. The fixed housing and the cavity wall of the mounting cavity fit tightly, improving the stability of the electronic components and reducing the problem of the massager loosening due to long-term vibration.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0046] Example 2 discloses the manufacturing process of the semi-rubber massager of Example 1, including the following steps: Assembling and fixing electronic components in a fixed housing to obtain an electronic component assembly; Referring to Figure 4, first molding: using a molding vulcanizing machine, a viscous first silicone material is added to the cavity of the first lower mold, a core is placed in, the first upper mold and the first lower mold are closed and molded, wherein the molding temperature is controlled at 110°C and the time is 2 minutes, forming a complete sleeve core on the outer surface of the core, and the core and sleeve core are detachably connected; Referring to Figure 5, second molding: using a molding vulcanizing machine, a viscous second silicone material is added to the cavity of the second lower mold, a sleeve core with a core is placed in, the second upper mold and the second lower mold are closed and molded, the molding temperature is controlled at 160°C and the time is 10 minutes, forming a complete sleeve body on the outer surface of the sleeve core, the sleeve body and the sleeve core are tightly bonded to form a protective sleeve; Remove the core, and the protective sleeve core forms an installation cavity with an opening corresponding to the core. The electronic component is installed into the installation cavity through the opening. During installation, the protective sleeve undergoes elastic deformation to tightly wrap the electronic component. The seal is then placed over the opening to obtain a semi-rubber-coated massager.

[0047] 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 a colorant by weight of the silicone rubber is added. The second silicone material consists of silicone rubber and 1% of a colorant by weight of the silicone rubber. In this embodiment, a commercially available silicone colorant is used, and the type is not limited.

[0048] 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. The silicone rubber used in the first and second silicone materials in this embodiment is made of 6 kg of vinyl 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.

[0049] Examples 3-4 differ from Example 2 in that the preparation process parameters are different, as detailed in Table 2 below.

[0050] Table 2 Process Parameters for Examples 2-4 Example 5-11 The difference between Example 5-11 and Example 2 is that the source of the silicone rubber is different, as detailed in Table 3 below.

[0051] Table 3. Source of silicone rubber in Examples 5-11 Performance Testing Test 1. Mechanical Performance Test: The first silicone material in Examples 2-11 was vulcanized at 120℃ for 10 minutes to obtain a test piece. According to the test method in GB / T 528-2009, the test piece was cut into type A standard ring specimens: 1) Test the tensile strength at break of the type A standard ring specimen (unit: MPa); 2) Perform a tensile test on the type A standard ring specimen, stretching it to an elongation of 250%, let it stand for 10 seconds, then cancel the stretching, wait for the test strip to recover for 30 seconds, and then 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; 3. Assembly Performance Test: Assemble the fixed shell along the opening of the protective sleeve. The size of the protective sleeve is the same as the size of the fixed shell. Repeat the assembly 3 times. Visually inspect the opening of the protective sleeve for signs of breakage or whitening. Test and record the test results.

[0052] The following are the performance test data of the semi-rubber massagers in Examples 2-11, as detailed in Table 4 below.

[0053] Table 4 Performance test data of the semi-rubber massager in Examples 2-11 Combining Examples 2-4 and Examples 5-7 with 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 fit with electronic components, and reduces loosening problems 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%.

[0054] 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 combination, resulting in a decrease in tensile strength at break and an increase in deformation rate.
