The installation slot 13 for the metal rod connecting the self-rotating component at the front end of the gearbox provides a telescopic and self-rotating space for the metal rod 8 connecting the self-rotating component at the front end of the gearbox. The outside of the hard silicone protective layer 1 with a suction cup structure is wrapped with a soft silicone functional layer 2. The power supply assembly 5 is connected to an external power supply assembly through the charging device 6 passing through the hard silicone protective layer 1 with a suction cup structure and the soft silicone functional layer 2.

[0022] The charging device 6 adopts a waterproof charging interface to ensure safety during the charging process. The charging part can select a pin-type interface, a data cable type, or a magnetic suction type power connection method for charging according to design requirements.

[0023] The electronic product components include core components such as the gearbox assembly 3, the control circuit board 4, and the power supply assembly 5. These components are precisely installed in the fixed placement slots inside the housing of the rigid silicone protective layer 1 with a suction cup structure according to a predetermined position and layout. The control circuit board 4 and the power supply assembly 5 are connected by wires, and the gearbox is connected to the circuit board through a specific interface. All connection points adopt reliable connection methods to ensure the stability and safety of the circuit.

[0024] Figures 4 - 9 provide the application scenarios of specific embodiments 2 - 3 of other external shape products of this application.

[0025] Further, the rigid silicone protective layer 1 with a suction cup structure is made of organosiloxane material, and the rigid silicone protective layer 1 with a suction cup structure is provided with wire installation holes and control switch slots. The charging device 6 is arranged to pass through the wire installation holes, and a control switch 14 is also installed on the control circuit board 4.

[0026] The rigid silicone protective layer 1 with a suction cup structure is made of organosilicone rubber or other soft materials (such as TPER, TPU, PVC, epoxy resin, etc.), and has excellent elasticity and heat resistance (the heat resistance range depends on the selected material). This layer can tightly wrap the electronic components to provide effective buffering and protection.

[0027] The soft silicone functional layer 2 is arranged outside the rigid silicone protective layer 1 with a suction cup structure and is also made of organosilicone rubber or other soft materials. This layer not only enhances the elasticity of the overall structure but also provides good touch and anti-slip performance.

Further, a buffer and reinforcement rib structure is provided at the outer peripheral edge of the hard silicone protective layer 1 with a suction cup structure. To improve the drop protection of the product, a reinforcement rib structure is designed at the corners of the hard silicone protective layer 1 shell with a suction cup structure to enhance the impact resistance of the shell. At the same time, key components such as the gearbox are effectively fixed and protected inside the shell to reduce the impact and damage during dropping.

By adopting the silicone oxygen alkane perfusion process and the secondary injection molding technology, the stable encapsulation and protection of electronic components are achieved, while improving the environmental friendliness and user experience of the product.

[0061] The utility model has the following characteristics:

[0062] I. Improvement in the encapsulation and protection effect of electronic components.

Using the mold silicone oxygen alkane perfusion process, the outside of the electronic components is encapsulated in a hard silicone protective layer housing with a suction cup structure. This hard silicone protective layer housing with a suction cup structure not only has excellent stability and impact resistance, but also provides fixed placement slots for the circuit board and power module, as well as a semi-surrounding slot for fixing the gearbox. The output part of the gearbox is exposed outside the hard silicone protective layer housing with a suction cup structure so as to be wrapped by the functional layer of soft silicone in subsequent steps, thereby achieving a better vibration effect. After the hard silicone protective layer housing with a suction cup structure is manufactured, the present application adopts the secondary injection molding technology to inject a functional layer of soft silicone with a skin-friendly material outside the hard silicone protective layer housing with a suction cup structure. This functional layer not only provides a comfortable user touch, but also further enhances the protection of electronic components.

[0063] II. Improvement in the sealing and sound insulation effects. In order to improve the sealing and sound insulation effects of the product, the present application adopts an integrated injection method to manufacture the functional layer of soft silicone and sets the position of the mold joint line in a circular shape at the bottom of the product. This design not only eliminates the traditional mold joint line, significantly improves the sealing of the product, but also enhances the sound insulation effect of the product and improves the user experience.

[0064] III. Improvement in environmental friendliness. The hard silicone protective layer housing with a suction cup structure replaces the traditional ABS and plastic electronic component housings, significantly improving the environmental friendliness of the product. The hard silicone material has excellent biocompatibility and degradability, is friendly to the environment, and meets the current environmental protection requirements.

[0065] IV. Improvement in the drop protection. Through the design of the hard silicone protective layer housing with a suction cup structure, the electronic components are better fixed and protected, enabling the product to effectively resist impact when dropped and protecting the internal electronic components from damage. This design significantly improves the drop protection of the product and extends the service life of the product.

[0066] Compared with the existing massagers with hard plastic ABS or plastic electronic component housings, the structure of this application is more environmentally friendly. The overall structure adopts a hard silicone rubber protective layer with a good elastic double-layer material and a suction cup structure, and a soft silicone rubber layer for buffering. After the improvement, the drop protection of the structure is significantly improved, and the structural use stability is better. In terms of the production process, the structure process has also been improved, optimizing the production steps, improving the production efficiency, and increasing the product yield rate. During specific production, according to the placement positions of each electronic component, a corresponding electronic component wrapping housing is designed and processed through a silicone oxane perfusion process, so that the electronic components are wrapped and protected by a hard silicone rubber protective layer with a suction cup structure made of silicone rubber. Using silicone oxane, the temperature resistance of silicone oxane is between 200 and 600 degrees, which significantly improves the temperature resistance compared to the traditional plastic. Then, through secondary injection molding, a soft silicone rubber layer is injection-molded outside the electronic components wrapped with the hard silicone rubber protective layer with a suction cup structure. The glue injection is carried out in an integrated sealing injection method, which is improved from the original upper and lower mold closing method to the existing integrated sealing injection, optimizing the production steps and increasing the product yield rate. The silicone rubber layer on the outer layer of the integrated sealing injection significantly improves the product sealing performance and sound insulation effect compared to the traditional mold closing for wrapping electronic products.
