[0024] 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.

[0025] like Figures 1-6 As shown, this utility model embodiment provides a massage head module, including a flexible circuit board 31, a temperature sensor, and multiple massage head structures 32. The temperature sensor is electrically connected to the flexible circuit board 31, and each massage head structure 32 is located on and electrically connected to the flexible circuit board 31. The temperature sensor is disposed in any one of the massage head structures 32.

[0026] In this embodiment, the heating element 322 and the flexible circuit board 31 are an integral structure, 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 integral 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.

[0027] Furthermore, the massage head structure 32 includes a vibration driving element 321 and a heating element 322. One side of the vibration driving 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 driving 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 driving element 321 together, the product assembly process is simplified, and assembly costs are reduced. Secondly, the integrated design reduces the number of connection points between components, lowers the risk of failure due to connection problems, and improves the reliability and stability of the massage head assembly.

[0028] Specifically, the flexible circuit board 31 has multiple connection points, and the vibration driving element 321 extends to one side with a pin portion, which connects 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 welding 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. In this embodiment, the driving element 21 is preferably a 1034 motor. Compared with 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 by directly welding the connection, reducing production steps and corresponding costs.

[0029] 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.

[0030] Furthermore, the heating element 322 includes a heating element body, on which at least one insulating layer is provided to ensure electrical insulation between the heating element body and other components during operation. This insulating layer not only improves structural safety but also prevents accidental current leakage, protecting user safety. 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 contact between the heating element and the external environment, avoiding current leakage or short circuits, 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. This arrangement provides electrical insulation protection in all directions of the heating wire, further enhancing the safety of the heating element 322.

[0031] 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.

[0032] 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. A temperature sensor is installed on the heating element 322 of any massage head structure 32. The positive and negative terminals of the temperature sensor are connected to the system circuit through the conductive paths on the flexible circuit board 31, enabling real-time monitoring of the temperature status of the heating element 322 and ensuring accurate and timely temperature control. Due to the close integration of the heating element 322 and the temperature sensor, the temperature sensor can accurately reflect the actual temperature of the heating element 322, thereby achieving precise temperature control of the massage head module. Through real-time data feedback from the temperature sensor, the control system can adjust the temperature of multiple massage head structures 32 according to the temperature sensor readings. Specifically, when the temperature sensor detects a temperature exceeding a preset range, the control system can reduce the temperature of the heating element by adjusting the current or voltage; conversely, when the detected temperature is below the preset range, the control system can increase the current or voltage to increase the temperature of the heating element. This centralized control method ensures the temperature uniformity and stability of the entire massage head module. In this embodiment, the temperature sensor is disposed on the heating element 322 in the first massage head structure 32 of the plurality of massage head structures 32. The temperature sensor is an NTC thermistor.

[0033] Specifically, the heating wire is arranged around the temperature sensor, enabling the temperature sensor to accurately and timely sense the temperature of the heating element 322. By monitoring the temperature of the heating element 322 in real time, the temperature sensor can provide accurate data, allowing the control system to adjust the working state of the heating element 322 as needed to avoid overheating and ensure safety and comfort.

[0034] 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.

[0035] Example 2

[0036] 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.
