[0003] The massager includes a jacket and electronic components such as a vibrating head, a motor, and a power supply installed in the jacket. In the process of processing the massager, the assembled electronic components are generally encapsulated and shaped first. The encapsulation and shaping requires first forming half of the protective cover to fix the electronic components, and then forming the other half of the protective cover, so as to form a complete protective cover on the outer surface of the electronic components. Then, the surface of the electronic components covered with the protective cover is processed twice to form a jacket, so that the electronic components are completely covered in the jacket.

[0004] However, the outer shell of the massager is generally made of plastic or silicone material, and the molding temperature is relatively high.

[0006] In the first aspect, the present application provides a semi-rubber-encapsulated massager, which includes a protective cover, an electronic component assembly and a seal, wherein the protective cover is provided with an installation cavity, the cavity wall of the installation cavity is provided with 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 shell and electronic components installed in the fixed shell, and the outer wall of the fixed shell and the cavity wall of the installation cavity are tightly fitted.

[0007] By adopting the above technical solution, the electronic components are pre-fixed in the fixed shell, then installed through the opening of the installation cavity of the protective cover, and then the opening is sealed with a seal. This semi-encapsulated structural design not only simplifies the preparation process, reduces the problem of the massager being affected by high temperature during the processing and molding process, improves the stability and service life of the massager, but also makes the overall shape of the massager more controllable, improving the performance and reliability of the product.

[0019] By adopting the above technical solution, the sleeve body is tightly bonded to the outer side of the sleeve core, so that the sleeve body and the sleeve core are tightly combined. When the electronic components vibrate, the protective cover has good structural stability and is not easy to loosen. The sleeve core is made of non-light-transmitting material, and the sleeve body is made of monochrome light-transmitting material. Under the combined effect of the sleeve core and the sleeve body, the protective cover can present different light-transmitting and refractive visual effects under the irradiation of external light sources, thereby forming a gradient color and texture structure, which improves the aesthetics and texture of the semi-rubber-encapsulated massager.

[0021] By adopting the above technical solution, the convex and concave patterns on the outer surface of the sleeve core are respectively engaged with the concave patterns and convex patterns of the sleeve body, thereby improving the bonding strength between the sleeve core and the sleeve body, ensuring the overall structural stability of the protective cover, and avoiding the problem of separation of the protective cover due to long-term vibration; at the same time, the combination of convex and concave patterns presents a uniform gradient color and texture structure, further enhancing the aesthetics and texture of the semi-rubber-coated massager.

[0022] In a second aspect, the present application provides a preparation process of a semi-encapsulated massager, comprising the following steps: Assembling and fixing the electronic components in a fixed housing to obtain an electronic component assembly; First molding: adding a first viscous silicone material into the cavity of the first lower mold, placing a core, closing the first upper mold and the first lower mold and performing compression molding, forming a complete sleeve core on the outer surface of the core, and the core and the sleeve core are detachably connected; Second molding: Add the second viscous silicone material into the cavity of the second lower mold, put the sleeve core with the core into it, close the second upper mold and the second lower mold and perform compression molding, form a complete sleeve body on the outer surface of the sleeve core, and the sleeve body and the sleeve core are tightly bonded to form a protective sleeve; The core is removed, and the protective cover forms an installation cavity corresponding to the position of the core and has an opening, and the electronic component assembly is installed into the installation cavity through the opening.

Under the action of the light-shielding filler, the sleeve core is not light-transmissive. If the color of the sleeve core needs to be adjusted, colorant can be added to obtain a sleeve core with different colors. Then, the second silicone material is used to form a light-transmissive sleeve body on the outer surface of the sleeve core. Under the action of the colorant, the sleeve body is transparent and colorful. Through two molding processes, the sleeve body and the sleeve core form a complete protective cover with good texture, elasticity and stability. Then remove the core, install the electronic component assembly in the installation cavity of the protective cover, and finally use a seal to seal the opening of the installation cavity to obtain a semi-encapsulated massager.

[0024] The present application solves the problem that the traditional preparation process requires multiple molding and shaping of electronic components through a semi-rubber-coated preparation process, and will not cause damage to the electronic components; the process is simple and easy to operate, suitable for industrial production, and the semi-rubber-coated massager obtained has good shape and performance stability.

[0026] By adopting the above technical scheme, the optimal amount of triallyl isocyanurate, 4-vinylbenzyl glycidyl ether and vinyl tri(methyl isobutyl ketoxime) silane plays a good synergistic role, which can further improve the crosslinking density of vinyl silicone rubber and methyl hydrogen silicone oil, and improve the flexibility and density of the prepared protective cover.

The fixed shell fits tightly with the cavity wall of the installation cavity, which improves the stability of the electronic components and reduces the problem of the massager loosening due to long-term vibration.

[0028] 2. By designing the fixed shell to be an upper shell and a lower shell, and providing limit blocks in the upper shell and / or the lower shell, the electronic components can be stably assembled in the fixed shell and easily disassembled, thereby reducing the problem of electronic components being easily loosened when the massager vibrates.

[0029] 3. By setting the core to a non-light-transmitting material and the body to a monochrome light-transmitting material, the protective cover formed by the combination of the convex and concave patterns of the core and the body can present different visual effects of light transmission and refraction under the illumination of an external light source, thereby forming a gradient color and texture structure, thereby improving the aesthetics and texture of the semi-rubber-encapsulated massager.

[0030] 4. The preparation process of the present application, through two molding processes, makes the sleeve body and the sleeve core form a protective sleeve with good texture, elasticity and stability; then the electronic component assembly is installed in the installation cavity of the protective sleeve and sealed, which solves the problem that the traditional preparation process requires multiple molding of the electronic components, and will not cause damage to the electronic components; the process is simple and easy to operate, suitable for industrial production, and the semi-rubber-encapsulated massager obtained has good shape and performance stability.
