[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] like Figures 1-3As shown, this embodiment of the invention provides a massage head structure, including a flexible circuit board 31, a temperature sensor, a vibration drive element 321 connected to the flexible circuit board 31, and a heating element 322 connected to the flexible circuit board 31. The temperature sensor is disposed on the heating element 322 for real-time monitoring of the temperature of the heating element 322. One side of the vibration drive element 321 is attached to the flexible circuit board 31, and the other side is attached to the heating element 322. This structure ensures close contact between the vibration drive element 321 and the heating element 322, thereby improving the system's heat conduction efficiency and vibration transmission effect. By integrating the temperature sensor, heating element 322, and vibration drive element 321 together, the product assembly process is simplified, and assembly costs are reduced. Furthermore, the integrated design reduces the number of connection points between components, lowering the risk of failure due to connection problems and improving reliability and stability.

[0023] The heating element 322 is integrally formed with the flexible circuit board 31, meaning that the heating element 322 is directly formed on the flexible circuit board 31 during the manufacturing process, eliminating the need for additional connecting parts and reducing assembly steps and costs. This integrated structure design not only improves the overall reliability and durability of the massage head module but also effectively enhances its heat conduction efficiency, ensuring uniform heating.

[0024] In this embodiment, the flexible circuit board 31 has connection points, and the vibration driving element 321 extends to one side with a pin portion. The pin portion is connected to the connection points to achieve a reliable connection between the vibration driving element 321 and the flexible circuit board 31. The vibration driving element 321 is connected to the flexible circuit board 31 by soldering or other reliable electrical connection methods. This method not only ensures the reliability of the electrical connection but also simplifies the manufacturing and assembly process. By reducing the number of connection points between components, the risk of poor contact is reduced, while production efficiency and product consistency are improved.

[0025] In this embodiment, the vibration drive element 321 is a 1034 motor. Compared to other products on the market, the 1034 motor does not require post-processing wiring and gluing, which significantly reduces material and processing costs. In traditional designs, the wiring and gluing process of the motor requires additional manual operation and material input, while this design simplifies this step through direct welding connection, reducing production steps and corresponding costs.

[0026] Furthermore, the width of the flexible circuit board 31 is 1 / 2 to 2 / 3 of the diameter of the vibration driving element 321. This size design ensures that the flexible circuit board 31 provides sufficient conductive paths and support structures while minimizing its volume, thus improving the compactness and portability of the overall structure.

[0027] Furthermore, the flexible circuit board 31 is provided with conductive paths, which are connected to the vibration drive element 321 and the heating element 322 respectively through precise wiring design. The conductive path design not only ensures efficient current transmission but also reduces resistance and energy loss, improving the overall efficiency of the massage head structure. The temperature sensor, vibration drive element 321, and heating element 322 are interconnected through the conductive paths on the flexible circuit board 31, simplifying the connections between components. The flexible circuit board 31 also possesses good bending and flexibility, adapting to different shapes and sizes, enhancing the product's adaptability and durability. Simultaneously, the use of the flexible circuit board 31 makes the entire massage head structure more compact and lightweight, suitable for the requirements of modern portable devices.

[0028] Furthermore, the heating element 322 is provided with at least one insulating layer to ensure electrical insulation between the heating element 322 and other components during operation. This insulating layer not only improves structural safety but also prevents accidental current leakage, protecting user safety. In this embodiment, the heating element 322 is a heating plate, which is connected to the conductive path on the flexible circuit board 31, thereby realizing current conduction and heat generation. When the heating plate is connected to the power system through the conductive path on the flexible circuit board 31, current is transmitted to the heating plate, the heating plate generates heat, and in conjunction with the vibration drive element 321, provides a warm massage effect.

[0029] In some embodiments, the insulating layer can be disposed on the surface of the heating element body to directly isolate the heating element from the external environment, effectively preventing the heating element from contacting the external environment, avoiding current leakage or short circuit, and protecting the stability of the heating element in high-temperature environments; in other embodiments, the insulating layer can be disposed on both sides of the heating wire body, which can provide electrical insulation protection in all directions of the heating wire, further improving the safety of the heating element 322.

[0030] Furthermore, a heating wire is provided on the side of the heating element 322 away from the vibration driving element 321. The heating wire can be designed in a spiral, mesh, or parallel arrangement to achieve uniform heat distribution and efficient heat conduction. The heating wire is typically made of nickel-chromium alloys, copper-nickel alloys, etc., which have excellent electrical conductivity and high-temperature stability.

[0031] The temperature sensor is mounted on the heating element, and the heating wire surrounds the temperature sensor, enabling the temperature sensor to accurately and promptly sense the temperature of the heating element 322. By monitoring the temperature of the heating element 322 in real time, the temperature sensor provides precise data, allowing the control system to adjust the operating state of the heating element 322 as needed to prevent overheating and ensure safety and comfort. In this embodiment, the temperature sensor is an NTC thermistor.

[0032] Furthermore, an adhesive layer is provided on the side of the heating element 322 near the vibration driving element 321. This adhesive layer is bonded to the vibration driving element 321, securely attaching the vibration driving element 321 between the heating element 322 and the flexible circuit board 31. By applying the adhesive layer between the heating element 322 and the vibration driving element 321, the stability of the vibration driving element 321 is improved, preventing displacement or loosening during operation. It also ensures efficient vibration and heat transfer, enhancing the reliability and performance of the overall system. Specifically, the adhesive layer can be made of various materials, such as thermally conductive adhesive, thermally conductive double-sided tape, or other materials with good thermal conductivity and adhesion. Preferably, the adhesive layer can be provided using a high-temperature curing adhesive, which maintains good adhesion and stability at high temperatures, preventing the heating element 322 from detaching from the vibration driving element 321 due to thermal expansion during operation.

[0033] Example 2

[0034] The difference between this embodiment and embodiment 1 is that the temperature sensor is located on one side of the flexible circuit board 31 to indirectly monitor the temperature of the heating element 322.
