Technical Field

[0001] This utility model relates to the field of beauty instrument technology, and in particular to a radio frequency electrode sheet and a dot matrix radio frequency beauty instrument. Background Technology

[0002] Most existing fractional radiofrequency (RF) beauty devices are handheld. Users must hold the device and continuously place the electrodes on the corresponding areas of the face to perform RF treatment. While this method offers some flexibility, allowing the device to be moved to the desired treatment location at any time, it is cumbersome for users, requiring them to maintain a handheld position for extended periods to perform multiple treatments in the same spot, resulting in a poor user experience.

[0003] In addition, the electrodes of existing radio frequency beauty masks or beauty devices are mostly made of hard metal materials. When the electrodes are in contact with the skin, they appear stiff and cannot fully conform to the user's facial curves, thus affecting comfort and user experience. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing fractional radio frequency beauty devices, which require prolonged handheld use and result in a poor user experience, and to provide a radio frequency electrode pad and a fractional radio frequency beauty device.

[0008] In one alternative technical solution, the surface of the electrode is coated with a hydrogel layer.

[0009] In one of the alternative technical solutions, the flexible substrate is provided with a plurality of clearance slots that connect to the outer edge of the flexible substrate.

[0010] The present invention also provides a dot matrix radio frequency beauty device, including a controller and at least one radio frequency electrode as described above, wherein the controller is connected to the electrical connection port of the radio frequency electrode.

[0011] In one of the alternative technical solutions, a handheld box is also included, and the controller is disposed within the handheld box.

[0012] In one of the alternative technical solutions, the handheld box is provided with a mode switching switch, which is connected to the controller.

[0013] In one of the alternative technical solutions, the handheld box is provided with a connecting cable, which is detachably connected to the electrical connection port.

[0014] In one of the alternative technical solutions, the number of radio frequency electrode sheets is three.

[0015] The above technical solution has the following beneficial effects: by using a flexible substrate and setting electrodes on the flexible substrate, and providing electrical connection ports on the outer edge of the flexible substrate, the radio frequency electrode sheet can be flexibly attached to the massage area. Users can complete the dot matrix radio frequency massage without holding the device, which is convenient and improves the user experience. Attached Figure Description

The clearance slots 111 are used to reduce stress concentration on the flexible substrate 11, thereby making it easier for the radio frequency electrode sheet 10 to fit into the massage area on different curved surfaces, further improving the fit and user experience.

[0036] Preferably, multiple clearance slots 111 are symmetrically arranged on the flexible substrate 11, such as... Figure 1 As shown, the flexible substrate 11 has symmetrical clearance slots 111 on opposite sides, which can further improve the fit, enhance the aesthetics of the radio frequency electrode sheet 10, and improve the user experience.
