Title:
MULTI-STAGE BOOST HANDHELD HIGH-FREQUENCY ELECTRO-THERAPEUTIC DEVICE AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/000752
Kind Code:
A1
Abstract:
The present invention relates to the field of beauty instruments. Disclosed are a multi-stage boost handheld high-frequency electro-therapeutic device and a control method therefor. A power source module with a relatively low voltage is configured in the high-frequency electro-therapeutic device, and power is supplied to a boost module by means of control of a control board, such that the possibility of a high voltage which is outputted by the boost module affecting the control board and even threatening the operation safety of a user at the control board is eliminated, thereby improving the safety and convenience of the high-frequency electro-therapeutic device when in handheld use. A multi-stage boost structure is configured, such that a hazard caused by a voltage swell in one step can be avoided; moreover, a low voltage is increased, by means of a first boost plate, to a voltage level which is required by a second boost unit, and the voltage is then increased to a high-voltage level by means of the second boost unit, such that the performance requirement for a circuit element and the design difficulty thereof are reduced and a boost circuit is simplified, so as to reduce the production difficulty, the maintenance difficulty and the production cost of the circuit, thereby further preventing the threat of a high voltage to a user operation, and ensuring the safety of a user when in handheld use.
