Such a design may provide better adaptability and comfort, and the comb teeth 200 may better fit the curves of the scalp, increasing user comfort. A cavity is provided within the soft rubber tooth body 220, and a conductor is provided within the cavity. Such a design allows electrical conductors to make electrical contact with the metal tooth head 210 and the PCB substrate 300. The presence of the conductor enables electrical connection between the comb teeth 200 and an electric circuit to transmit current or signals. The metal tooth head 210 is fixed to the other end of the soft rubber tooth body 220 and is connected to the tooth box body 100 by a flexible connection of the soft rubber tooth body 220. This combination design allows the comb teeth 200 to combine the electrical conductivity of the metal tooth head 210 with the flexibility and comfort of the soft rubber tooth body 220. Electrical connection of the comb teeth 200 is achieved via a PCB board 300 electrically connected to the comb teeth 200.

In this embodiment, the comb assembly achieves optimization of comfort and electrical connection through flexible connections, conductor design, and the combination of metal tooth head 210 and soft rubber tooth body 220. Such a design can improve the effectiveness of the comb teeth 200 and the user's experience, making the EMS/RF functional hair care comb more suitable for scalp stimulation and RF therapy.

In addition, the soft rubber tooth main body 220 made of silica gel is relatively soft and can reduce friction and static electricity generation on hair, thereby reducing the possibility of hair damage or breakage. A metal head can be located at the tip of the comb teeth 200 to provide better electrical conductivity for the transmission of EMS/RF functions and protect the structural integrity of the comb teeth 200 at the same time.

In this embodiment, the electrical conductor is in tight contact with the metal tooth head 210. The tight contact can ensure the adhesion between the conductor and the metal tooth head 210, allowing a stable electrical connection. Even if a drop or impact occurs, the contact between the conductor and the metal tooth head 210 is reliable and will not cause power outage or signal interruption. Thereby, the earthquake resistance and fall resistance of the comb tooth assembly can be improved.

In this embodiment, the electrical conductor is a conductive spring needle 400 with one end welded to the PCB board 300 and the other end in tight contact with the metal tooth head 210. The conductive spring needle 400 has good conductivity as an electric conductor. By welding one end of the conductive spring needle 400 to the PCB board 300, a stable and reliable electrical connection can be achieved.

The close contact between the conductive spring needle 400 and the metal tooth head 210 can effectively transmit current or signals. By ensuring close contact between the conductive spring needle 400 and the metal tooth head 210, the contact resistance can be minimized and the efficiency and stability of the electrical connection can be improved. Since the spring needle acts as an electrical conductor and the spring needle itself has compressible properties, the metal toothed head 210 not only flexes relative to the spring needle when in use, but also conforms to the curve of the scalp. It can be compressed along the direction of the needle's wind, providing a higher cushioning effect during use.

In another embodiment, as shown with reference to FIGS. 3-4, the electrical conductor is a ball 500, at least two balls are disposed within the cavity of the soft rubber tooth body, and the balls are: It is in tight contact with the metal tooth head. Appropriate balls 500 are selected based on the size of the cavity within the tooth body of the soft rubber tooth body 220, and two or more balls 500 are arranged in parallel to constitute an electrical conductor, and the balls 500 are arranged in parallel to form a conductor. Located within a cavity. Two or more balls 500 are in tight contact with the metal tooth head 210 and the PCB board 300. At the time of assembly, first, the comb teeth 200 are fixed inside the tooth box main body 100, and the comb teeth 200 are penetrated into the tooth box main body 100. After that, put the ball 500 into the cavity in the soft rubber tooth body 220, cover it with the PCB board 300, press the ball 500 until it makes contact, and finally cover the cover plate 600 of the tooth box body 100 and press the PCB board 300 downward. Then, the fixing of the comb teeth 200 and the attachment of the ball 500 and the PCB board 300 are completed.

The contact aspect of ball 500 is more direct without the welding process. Ball 500 is a relatively large diameter conductor and can provide a more stable electrical connection. In contrast, the stability of conductive spring needle 400 can be affected by its elongated structure. Ball 500 has higher stability and can maintain a more stable electrical connection during use.

The two balls 500 arranged side by side cannot function as electrical conductors and provide a compressive buffer area in the direction of the comb teeth 200 for the spring needles, but a relative rotation between the balls 500 occurs. Therefore, the metal tooth head 210 can flex more flexibly with respect to the PCB board 300.
