Description

Technical Field

[0001] The utility model relates to the technical field of medium frequency therapeutic instruments, in particular to a medium frequency therapeutic instrument with waterproof and heat dissipation functions. Background Art

[0002] Medium-frequency therapeutic devices, commonly used in medical treatments, can be used for analgesia, improving local blood circulation, and promoting the resolution of inflammation. In cosmetic medicine, they can also be used to soften scars and loosen adhesions. A medium-frequency therapeutic device typically consists of a main unit, a hand-operated unit, and electrodes. The main unit transmits medium-frequency current, which is then applied to the user through the electrodes for treatment. The hand-operated unit connects to the main unit to control the delivery of the medium-frequency current.

[0003] In existing main units, a medium-frequency current is mostly generated by a single integrated circuit board, and the medium-frequency current generated by the circuit board is transmitted to the electrode sheet to treat the user's skin. However, when it is desired to achieve different degrees of treatment functions, different types of medium-frequency currents are usually required. It is difficult to use a single circuit board for planning to achieve the above functions. For non-single integrated circuit boards, too many circuits are integrated on one circuit board, and the heat generated will be more concentrated. If the heat cannot be dissipated in time, it is easy to affect the performance of the electronic devices on the circuit board; for therapeutic devices with an integrated manual control unit and a main unit (the manual control unit is embedded in the shell of the main body), when water is suddenly splashed onto the manual control unit or the surface of the main body, it is easy to penetrate from the position of the manual control unit, which can easily affect the use of electronic devices.

[0004] Therefore, the present invention proposes a medium frequency therapeutic apparatus with waterproof and heat dissipation functions. Utility Model Content
