[0028] Please refer to Figure 1 , Figure 1 This is a perspective view of a head-mounted brain nerve stimulation device. This embodiment provides a head-mounted brain nerve stimulation device, which includes a head-mounted support 1 and two sets of stimulation components 2. The two sets of stimulation components 2 are connected to the head-mounted support 1, which is used for wearing and securing the device. The two sets of stimulation components 2 generate low-frequency pulses through connection with an external electrical pulse supply device to stimulate the user's brain nerves.

[0029] Specifically, the headband 1 includes two adjusting members 11 and an adjusting band 12. The two adjusting members 11 are respectively disposed at opposite ends of the adjusting band 12, and each adjusting member 11 is movably connected to the adjusting band 12. Each stimulation component 2 is connected to one adjusting member 11, and the stimulation component 2 can rotate relative to the adjusting member 11.

[0030] In practical use, the head-mounted brain nerve stimulation device is connected to an external electrical pulse supply device, and then worn on the user's head. By moving the adjustment component 11 relative to the adjustment band 12, the position of the stimulation component 2 relative to the adjustment band 12 is changed. By rotating the stimulation component 2, the angle of the stimulation component 2 is adjusted so that the stimulation component 2 fits snugly against the user's head. In this way, through the adjustment component 11 and the stimulation component 2, the head-mounted brain nerve stimulation device is adjustable to adapt to different users' heads, thereby achieving a better stimulation effect.

[0031] Please refer to Figures 2-5 , Figure 2 This is a schematic diagram of the adjustment belt. Figure 3 This is an enlarged view of part A. Figure 4 This is a sectional view of the adjusting component. Figure 5 This is an enlarged view of part B. Further, each end of the adjusting belt 12 is provided with a locking portion 121. The locking portion 121 includes multiple locking teeth 1211 equidistantly spaced along the length of the adjusting belt 12, with a locking groove 1212 formed between adjacent locking teeth 1211. Each adjusting member 11 has an adjusting groove 110, and the locking portion 121 passes through the adjusting groove 110 of one adjusting member 11. The opening of the adjusting groove 110 is provided with a limiting protrusion 1101 that matches the locking groove 1212, and the limiting protrusion 1101 is movably locked into the locking groove 1212.

[0032] When the adjusting belt 12 and the adjusting member 11 are connected, one end of the adjusting belt 12 extends into the adjusting groove 110 of the adjusting member 11, and any locking groove 1212 engages with the limiting protrusion 1101, so that the first adjusting member 11 is stably connected to the adjusting belt 12. By engaging the locking grooves 1212 at different positions with the limiting protrusions 1101, the position of the adjusting belt 12 relative to the adjusting member 11 is adjustable.

[0033] Preferably, each locking tooth 1211 has guide surfaces 12110 on its upper and lower sides, and the inclination directions of the guide surfaces 12110 on the upper and lower sides of the locking tooth 1211 are opposite. The limiting protrusion 1101 has abutment surfaces 11011 on its upper and lower sides, and the abutment surfaces 11011 on the upper and lower sides of the limiting protrusion 1101 are in opposite inclination directions. When the limiting protrusion 1101 is engaged in the locking groove 1212, the lower guide surface 12110 of the locking tooth 1211 fits against the upper abutment surface 11011 of the limiting protrusion 1101, so that the limiting protrusion 1101 and the locking groove 1212 remain stable. Since both the guide surface 12110 of the locking tooth 1211 and the abutment surface 11011 of the limiting protrusion 1101 are inclined surfaces, when the length of the adjusting belt 12 needs to be changed, only a downward or upward force needs to be applied to the adjusting belt 12. When the adjusting belt 12 is under force, the guide surface 12110 of the locking tooth 1211 slides relative to the abutment surface 11011 of the limiting protrusion 1101. When the desired length is reached, the force is stopped, and the limiting protrusion 1101 re-engages with the locking groove 1212. This allows for the sliding connection of the adjusting belt 12.

[0034] In this way, the adjusting belt 12 and the adjusting member 11 can be slidably connected through the adjusting part 112 and the limiting protrusion 1101 while maintaining a stable connection.

[0035] Please refer to Figure 2 To prevent the adjustment belt 12 from detaching from the adjustment member 11, the headband 1 also includes two limiting members 13. The two limiting members 13 are respectively disposed at opposite ends of the adjustment belt 12, and the outer diameter of the limiting members 13 is larger than the inner diameter of the adjustment groove 110. Thus, during connection, the adjustment belt 12 slides through the adjustment groove 110, and the limiting members 13 are connected to the ends of the adjustment belt 12 to prevent the adjustment belt 12 from moving beyond its limit and slipping off the adjustment member 11.

[0036] Please refer to Figure 1 Furthermore, each stimulation assembly 2 includes a rotating connector 21 and two stimulation elements 22. The rotating connector 21 is hinged to the inner side of the adjusting member 11, and the two stimulation elements 22 are respectively disposed at both ends of the rotating connector 21. Each stimulation element 22 is hinged to the rotating connector 21, and the direction of the rotation axis of the stimulation element 22 is perpendicular to the direction of the rotation axis of the rotating connector 21.

[0037] By superimposing the two rotation directions of the rotating connector 21 and the stimulating element 22, the stimulating component 2 can be adjusted to multiple angles, allowing the stimulating component 2 to better fit the user's head.

[0038] Please refer to Figure 6 and Figure 7 , Figure 6 This is a schematic diagram of the first shell and the second shell. Figure 7This is a schematic diagram of the coil array mounted on the second housing. The stimulating element 22 includes a first housing 221, a second housing 222, and a coil array 223. The first housing 221 is hinged to a rotating connector 21, allowing the first housing 221 to rotate relative to the rotating connector 21. During connection, the coil array 223 is disposed within the mounting groove 2221, and the second housing 222 covers the first housing 221, so that the coil array 223 is accommodated within both the first housing 221 and the second housing 222.

[0039] A mounting groove 2221 is formed within the second housing 222, and two annular winding walls 22211 are arranged at intervals along the length of the mounting groove 2221. A gap is formed between the outer side of each annular winding wall 22211 and the inner side of the second housing 222. The coil array 223 includes two sets of coils 2231, and a coil is disposed in the gap between each annular winding wall 22211 and the inner side of the second housing 222. The two sets of coils 2231 are arranged such that the coil array 223 is in the shape of "∞".

[0040] When the head-mounted brain stimulation device is used, power is supplied to the coil array 223. When the coils 2231 are energized, they generate magnetic pulses, which in turn generate pulse signals to stimulate the user's brain nerves. Because the magnetic field strength generated below the tangent portion of the two circular coils 2231 in the "∞"-shaped coil array 223 is mutually reinforcing, the coil array 223 produces a higher magnetic field strength, thus providing focused magnetic stimulation. It should be noted that the magnetic poles of the coil arrays 223 in the two stimulation elements 22 are oriented in the same direction, so that the two stimulation elements 22 cover a larger area of ​​magnetic field.

[0041] Each coil 2231 is made of wire with a diameter of 0.3 mm, and the inner diameter of the coil 2231 is 35 mm, 37 mm or 39 mm, and the outer diameter of the coil 2231 is 40 mm, 42 mm or 44 mm.

[0042] Furthermore, the outer side of the second housing 222 is formed with a fitting surface 2222, and the fitting surface 2222 is curved. When in use, the curved fitting surface 2222 fits the user's head more closely, making it ergonomic.

[0043] Please refer to Figure 8 , Figure 8 This is an exploded view of the adjustment component. The adjustment component 11 includes a receiving portion 111 and an adjustment portion 112. An adjustment groove 110 is formed in the adjustment portion 112, allowing the adjustment portion 112 to be movably connected to the adjustment belt 12. The receiving portion 111 covers one side of the adjustment portion 112. A first wire-passing hole 1111 and a second wire-passing hole 1112 are respectively formed on opposite sides of the receiving portion 111, and the first wire-passing hole 1111 and the second wire-passing hole 1112 are connected. The stimulation component 2 is rotatably connected to the side of the adjustment portion 112 opposite to the receiving portion 111.

[0044] During installation, the connecting wires of the head-mounted brain nerve stimulation device pass through the first wire hole 1111 and the second wire hole 1112 in sequence, so that part of the connecting wires are located in the receiving part 111, which facilitates the arrangement and storage of the connecting wires.

[0045] In summary, by movably connecting the adjusting element 11 to the adjusting band 12 and rotatably connecting the stimulation component 2 to the adjusting element 11, the stimulation component 2 can be adjusted in multiple directions. Furthermore, by rotatably connecting the stimulation element 22 to the rotating element, the adjustable directions are further increased, allowing the head-mounted brain nerve stimulation device to be adjusted according to the head size of different users, ensuring that the stimulation element 22 fits the user's head to the maximum extent and achieves the best stimulation and treatment effect.

[0046] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
