[0026] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0027] Example 1

[0028] Please refer to Figure 1 As shown, this embodiment provides a massage head assembly, which includes: a bracket 100, a massage head 200, an electromagnetic coil 300 and a heat-conducting end cover 400. The bracket 100 is used to connect the massage device. The massage head 200 is provided with an annular metal insert 201 inside. The metal insert 201 is rotatably connected to the bracket 100, and the insert has an end exposed from the massage head 200. The electromagnetic coil 300 is provided at one end of the metal insert 201. The metal insert 201 is located within the range of the alternating magnetic field generated by the coil. The other end of the metal insert 201 is covered with a heat-conducting end cover 400.

[0029] In this embodiment, the bracket 100 can be connected to the movement of the external massage device by bolt connection or welding. The massage head 200 is rotatably arranged on the bracket 100, and the user's body is massaged and kneaded by the rotation of the massage head 200. Specifically, the massage head 200 is a drum-like structure with two ends open and a hollow interior, and a ring-shaped metal insert 201 is arranged inside the massage head 200. The metal insert 201 is rotatably connected to the bracket 100 to support and fix the massage head 200. The massage head 200 is covered on the outside of the metal insert 201 and is in close contact with the metal insert 201. An electromagnetic coil 300 is arranged at one end of the metal insert 201, and the electromagnetic coil 300 is connected to an AC power supply. The metal insert 201 is located within the range of the alternating magnetic field generated by the coil. As the current in the electromagnetic coil 300 changes continuously, the metal insert 201 generates heat due to the principle of electromagnetic induction, and the heat is transmitted to the massage head 200 connected to the metal insert 201. The massage head 200 contacts the user's body, and the massage head 200 is heated by the electromagnetic coil 300 to improve the comfort during massage. Compared with the traditional heating method of heating resistance wire, the use of electromagnetic induction principle can increase the heating speed and reduce the start-up time. The metal insert 201 is used as a supporting element to support the massage head 200, and at the same time as a heating element, it directly generates heat and quickly transfers heat to the massage head 200, further reducing the heating time. In order to facilitate the installation of the metal insert 201 and ensure the smooth rotation of the metal insert 201 after being connected to the bracket 100, both ends of the metal insert 201 are exposed to the massage head 200. One end of the metal insert 201 is rotatably connected to the bracket 100, and the other end of the metal insert 201 is covered with a heat-conducting end cover 400, and the edge of the heat-conducting end cover 400 is in contact with the massage head 200. On the one hand, the heat-conducting end cover 400 and the bracket 100 cover the metal insert 201 to prevent the metal insert 201 from being exposed or contacting with other objects to cause safety accidents. On the other hand, the heat-conducting end cover 400 is in contact with the metal insert 201 and the massage head 200 at the same time, forming a heat-conducting channel, transferring the heat from the side of the metal insert 201 to the massage head 200, making full use of the originally lost energy and improving energy efficiency.

[0030] Optionally, see Figure 1 As shown, in some implementations of this embodiment, a plurality of circular ribs are evenly spaced circumferentially arranged on the metal insert 201, and a portion of the circular ribs is opened and wrapped in the massage head 200, and a portion is exposed from the massage head 200. The heat-conducting end cover 400 is tightly connected to the exposed portion of the circular ribs by screws. The heat-conducting end cover 400 is detachably connected to the circular ribs, which is convenient for assembly and subsequent disassembly and maintenance. When the metal insert 201 generates heat, most of the heat is directly transferred to the massage head 200, and part of the heat is conducted from the circular ribs to the heat-conducting end cover 400.

[0031] Optionally, in some implementations of this embodiment, a magnetic isolation sheet 500 is provided at one end of the electromagnetic coil 300 away from the metal insert 201 .

[0032] Please refer to Figure 1 As shown, in this embodiment, a magnetic isolation sheet 500 is provided at one end of the metal inlay 201 away from the heat-conducting end cover 400, and the electromagnetic coil 300 is located between the metal inlay 201 and the magnetic isolation sheet 500. The magnetic isolation sheet 500 and the heat-conducting end cover 400 respectively encapsulate the metal inlay 201 and the electromagnetic coil 300 from the left and right ends to prevent the electromagnetic coil 300 and the metal inlay 201 from being exposed. The magnetic isolation sheet 500 shields the electromagnetic coil 300 to ensure that the changing magnetic field generated by the electromagnetic coil 300 mainly acts on the metal inlay 201, and most of the energy of the electromagnetic wave generated by the electromagnetic wire is absorbed by the metal inlay 201, which greatly improves the energy efficiency. The magnetic isolation sheet 500 prevents the changing magnetic field from affecting the external metal and causing heat, which improves safety while avoiding energy loss, ensuring the heating effect and saving energy.

[0033] Optionally, in some implementations of this embodiment, the bracket 100 includes a connecting portion 101 and a columnar supporting portion 102 , one end of the supporting portion 102 is fixedly connected to the connecting portion 101 , and the metal insert 201 is rotatably mounted on the supporting portion 102 .

[0034] Please refer to Figure 1 and Figure 3 As shown, the bracket 100 includes a disc-shaped connecting portion 101 and a columnar supporting portion 102. A plurality of connecting holes may be provided on the connecting portion 101, so as to facilitate installation on the massage movement of an external massage device through bolts or studs. The disc-shaped connecting portion 101 can increase the contact area with the massage device, and can be fixed with a plurality of connecting bolts to improve the stability after installation. The supporting portion 102 is a cylindrical structure, and the diameter of the supporting portion 102 is smaller than that of the connecting portion 101. One end of the supporting portion 102 is fixed to the connecting portion 101, and the metal insert 201 is rotatably mounted on the supporting portion 102. The entire bracket 100 has a simple structure, which is convenient for the assembly of the metal insert 201, and can also ensure the smooth rotation of the metal insert 201 after installation.

[0035] Optionally, in some implementations of this embodiment, the support portion 102 and the connecting portion 101 are integrally formed to improve the supporting strength of the support portion 102 and the connecting portion 101, thereby increasing the service life of the support portion 102 and preventing the support portion 102 from loosening and shaking during use, thereby affecting the massage effect.

[0036] Optionally, in some implementations of this embodiment, a rotating bearing 600 is provided between the metal insert 201 and the support portion 102 .

[0037] During the massage operation, the massage head 200 rotates continuously and moves in accordance with the human body to perform massage. In order to avoid the metal insert 201 from wearing the support part 102 of the bracket 100, a rotating bearing 600 is provided between the metal insert 201 and the support part 102 to avoid the metal insert 201 from wearing the support part 102, thereby increasing the service life of the bracket 100 and improving the smoothness of the massage head 200 when rotating, thereby improving the massage comfort.

[0038] Optionally, in this embodiment, the massage bearing can be made of a wear-resistant material. Preferably, a wear-resistant plastic material can be used, which is light in weight, high in strength, and will not be affected by the electromagnetic coil 300 to generate eddy currents.

[0039] Optionally, in some implementations of this embodiment, a fixed baffle 700 is provided at one end of the support portion 102 away from the connection portion 101 , and the fixed baffle 700 abuts against an end surface of the massage head 200 or the rotating bearing 600 .

[0040] Please refer to Figure 1 As shown, a connection screw hole is provided at one end of the support portion 102 away from the connection portion 101, and a fixed baffle 700 is disposed at the movable end of the support portion 102, and the fixed baffle 700 is detachably connected to the support portion 102 via a stud. After installation, the fixed baffle 700 abuts against the end surface of the massage head 200 or the rotating bearing 600 away from the connection portion 101 of the bracket 100, thereby limiting and fixing the massage head 200 and the metal insert 201, and preventing the massage head 200 and the metal insert 201 from falling off from the support portion 102.

[0041] Optionally, in some implementations of this embodiment, a wear-resistant sheet 800 is provided on the support portion 102 , and the wear-resistant sheet 800 is located between the metal insert 201 and the electromagnetic coil 300 .

[0042] Please refer to Figure 2As shown, the wear-resistant sheet 800 is located between the metal insert 201 and the electromagnetic coil 300, and is used to separate the metal insert 201 and the connecting portion 101 of the bracket 100. Since the metal insert 201 and the bracket 100 rotate relative to each other, the metal insert 201 and the bracket 100 will inevitably rub against each other and cause wear. The wear-resistant sheet 800 is provided for isolation to ensure the safety and practical life of the bracket 100.

[0043] Optionally, in some implementations of the present embodiment, the wear-resistant sheet 800, the electromagnetic coil 300 and the magnetic isolation sheet 500 are all annular structures. On the one hand, they are convenient for assembly on the support portion 102 of the bracket 100. On the other hand, they are also adapted to the shape of the massage head 200 and the metal insert 201, so as to facilitate the rotation of the massage head 200 and improve the heating effect.

[0044] Optionally, in some implementations of this embodiment, the massage head assembly further includes a temperature sensor 1000 , which is disposed on the bracket 100 , and the temperature sensor 1000 is used to detect the temperature of the massage head 200 .

[0045] Please refer to Figure 2 As shown, the support part 102 of the bracket 100 is set as a hollow structure, and the temperature sensor 1000 is installed inside the support part 102 for real-time detection of the temperature of the massage head 200. The temperature sensor 1000 is connected to the external control system signal and transmits the detected temperature information to the control system, so that the control system can adjust the temperature of the massage head 200 in time. That is, the temperature comfort during use is guaranteed, the massage comfort is improved, and the temperature can be adjusted in advance according to the physical condition of each person, ensuring safety and saving electricity.

[0046] Optionally, in some implementations of this embodiment, the massage head assembly further includes a fuse 900 , and the fuse 900 is connected in series with the electromagnetic coil 300 .

[0047] Please refer to Figure 1 As shown, a mounting groove is provided on the connection portion 101 of the bracket 100, and a fuse 900 is fixed in the mounting groove. The fuse 900 is connected in series with the electromagnetic coil 300, and the fuse 900 plays a role of power-off protection, thereby improving safety.

[0048] Optionally, the fuse 900 may be a thermal fuse 900 . When the temperature of the massage head 200 exceeds a threshold value, the fuse 900 is melted by the heat, thereby disconnecting the power supply and de-energizing the electromagnetic coil 300 , so that the temperature of the massage head 200 drops.

[0049] Optionally, in some implementations of this embodiment, the massage head 200 is made of thermally conductive silicone material.

[0050] The massage head 200 is in contact with the user's body, so the massage head 200 uses a soft material with a certain elasticity to improve the comfort during massage. Preferably, the massage head 200 uses thermal conductive silicone to quickly transfer the heat generated by the metal insert 201 to the surface, and the thermal conductive silicone itself has a certain heat resistance. As long as the temperature does not exceed the threshold, deformation and damage will not occur.
