Description

Technical Field

[0001] The utility model relates to a beauty instrument. Background Art

[0002] Radio frequency beauty devices are the mainstream technology products for facial rejuvenation. The electrode heating area, the uniformity of temperature distribution in the heating area, and the accuracy of the heating temperature are all factors that evaluate the performance of radio frequency beauty devices. Existing home handheld radio frequency beauty device electrodes all use bipolar radio frequency for safety reasons. According to the electrode distribution method, it can be divided into two categories: nested distribution and separated distribution.

[0003] For example, the Chinese utility model patent "Beauty Instrument" with authorization announcement number CN218474790U discloses a first functional electrode assembly in the beauty instrument, which includes a first electrode and a second electrode that are spaced and nested. In this distributed structure of the electrode assembly, the heating area is concentrated in the area between the inner and outer electrodes, while the area within the outer boundary of the inner circle electrode is almost not heated, which leads to uneven heating areas and hollow ring distribution of the heating areas. In addition, in order to obtain a favorable heating surface, the electrode of this structure usually has a larger area, which is suitable for flat areas on the face, but is not conducive to heating of curved surfaces, curved corners, and narrow areas around the eyes. In these areas, uneven heating or even no heating will occur due to uneven contact between the electrode and the skin.

[0004] For example, the Chinese invention patent application "A Beauty Instrument Control Method and Related Equipment" with publication number CN115501479A discloses the use of point electrodes with a separated distribution structure. Point electrodes have no gain in heating area and are not conducive to uniform and precise control of temperature zones. The more point electrodes there are, the more dispersed the number of small temperature zones between the electrodes, and therefore the more vacancies between the temperature zones, resulting in uneven temperature zones.

[0005] For example, the Chinese invention patent application "Multi-channel temperature-controlled radio frequency beauty device" with publication number CN109865196A adopts a strip electrode with a separated distribution structure. The heating area of ​​the strip electrode is relatively concentrated, so the temperature distribution is relatively uniform, which also provides a favorable basis for monitoring and regulating skin temperature. However, there are still the following problems: it is inconvenient for locations such as the nose with large curvature or narrow eyes. The existing strip-shaped electrodes have a large two-dimensional plane size and are suitable for flat parts of the face, but when used in parts with large curvature or narrow areas, the sensor contact effect is not good, resulting in unstable energy output. Especially for the eyes, there is also a risk of damaging the eyeball due to excessive energy. Therefore, the existing strip electrode solution is not suitable for the eyes. Utility Model Content

[0015] In order to better fit the user's skin, the first electrode and the second electrode are arranged on the active surface through an elastic member.

[0018] Optionally, the first electrode and the second electrode are continuous strip electrodes; or

[0019] The first electrode and the second electrode are multiple segments of electrode strips arranged at intervals along the extension direction of the active surface.

The working surface of the beauty instrument is set to be L-shaped, so that the flat part of the working surface can act on relatively flat areas such as the face and eyes, while the bent part can act on the curved surface and curved corners of the face, thereby ensuring that all areas of the face can be effectively acted on, and the acting position is not limited. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 1 It is a three-dimensional diagram of the beauty instrument in the embodiment of the utility model. DETAILED DESCRIPTION

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] like Figure 1 As shown, the beauty instrument in this embodiment includes a housing 1 and an electrode assembly 2 arranged on the housing 1.

[0024] The housing 1 in this embodiment is in the form of a straight rod as a whole. A control circuit board connected to the electrode assembly 2 with electrical signals may be provided in the housing 1 , so that the electrode assembly 2 is powered and controlled to work via the control circuit board.

[0025] The housing 1 has an L-shaped cross-section action surface 11. In order to facilitate the action on the user's skin, the action surface 11 is formed at the top of the housing 1. The L-shaped action surface 11 has a first action surface 111 and a second action surface 112 set at an angle. The angle between the first action surface 111 and the second action surface 112 is Y, 70°≤Y≤120°. In this embodiment, the angle Y between the first action surface 111 and the second action surface 112 is 90°. In addition, the angles between the central axis of the housing 1 described on the action surface 11 and the two action planes of the action surface 11 are both acute angles, which can make it easier for the user to hold the housing 1 and use the first action surface 111 or the second action surface 112.

[0026] The electrode assembly 2 includes a first electrode 21 and a second electrode 22, and the first electrode 21 and the second electrode 22 are arranged in parallel on both sides of the active surface 11 along the extension direction of the active surface 11, that is, the first electrode 21 and the second electrode 22 are distributed in parallel on both sides of the first active surface 111 and the second active surface 112. The spacing between the first electrode 21 and the second electrode 22 can be specifically determined according to the width of the first active surface 111 and the second active surface 112, and the spacing between the first electrode 21 and the second electrode 22 can be selected in the range of 1mm-20mm, preferably selecting a suitable spacing data in the range of 4mm-6mm.

[0027] The first electrode 21 and the second electrode 22 can be made of various electrode materials used in beauty devices in the prior art. For example, a copper strip that takes both electrical conductivity and oxidation resistance into consideration can be preferred, and a gold electrode can be plated on the copper strip. Alternatively, electrodes made of silver, copper, gold, aluminum, stainless steel, and other materials can be selected. As required, the first electrode 21 and the second electrode 22 can be continuous strip electrodes, or the first electrode 21 and the second electrode 22 can be multiple segments of electrode strips arranged at intervals along the extension direction of the active surface 11.

[0028] In order to better achieve the effect on the eye area, the extension lengths of the first action surface 111 and the second action surface 112 are different, so that the plane areas of the first action surface 111 and the second action surface 112 are different, and the plane with a smaller area is more suitable for the eye area, while the plane with a larger area is more suitable for the eye area. In this embodiment, the extension length of the first action surface 111 is greater than the extension length of the second action surface 112. Correspondingly, the length of the first electrode 21 and the second electrode 22 distributed on the first action surface 111 is A, and the length of the first electrode 21 and the second electrode 22 distributed on the second action surface 112 is B, A>B. In this embodiment, the length of the first electrode 21 and the second electrode 22 is X. When specifically designed, the corresponding length data can be specifically selected within the following distance range: 10mm≤X≤25mm, 5mm≤A≤12mm, 1mm≤B≤4mm. More preferably, 20mm≤X≤25mm, 8mm≤A≤12mm, 2mm≤B≤4mm.

[0029] The first electrode 21 and the second electrode 22 can be directly fixed on the housing 1, and in order to facilitate the fixed installation of the first electrode 21 and the second electrode 22 and improve the installation efficiency, fixing grooves are respectively provided on the action surface 11 corresponding to the setting positions of the first electrode 21 and the second electrode 22, and the first electrode 21 and the second electrode 22 are embedded in the fixing grooves and the upper surfaces protrude from the top of the fixing grooves. The height of the first electrode 21 and the second electrode 22 protruding from the top of the fixing groove can be more than 0.5 mm, and the height protruding from the top of the fixing groove is preferably selected within the range of 2 mm-4 mm. In this way, the first electrode 21 and the second electrode 22 can better contact the user's skin, thereby achieving a beauty effect.

[0030] In order to better fit the user's skin, the first electrode 21 and the second electrode 22 are arranged on the active surface 11 through an elastic member, so that the first electrode 21 and the second electrode 22 can float up and down based on the action of the elastic member, thereby better matching the changes in the user's facial curve and fitting more closely to the user's facial skin, thereby improving the effect.

[0031] In order to provide real-time feedback of skin temperature and ensure safety in use, a plurality of temperature sensors 3 are provided on the action surface 11 between the first electrode 21 and the second electrode 22 along the extension direction of the action surface 11. In order to facilitate real-time acquisition of facial skin temperature when the bent portion of the action surface 11 is used for action, the bent portion of the action surface 11 is provided with a temperature sensor 3.

[0032] A refrigeration module is provided on the housing 1 near the first electrode 21 and the second electrode 22. The refrigeration module can be various small modules in the prior art that can achieve refrigeration effects, such as semiconductor refrigeration sheets. The position of the refrigeration module can be set as needed. For example, the refrigeration module can be set on the side of the electrode assembly 2 in a heat transfer relationship with the electrode assembly 2, and then the cold energy is transferred to the skin through the electrode assembly 2. The refrigeration module can also be set in the area near the click assembly in the housing 1, and then the cold energy is transferred to the skin through the active surface 11 of the housing 1. The refrigeration module can be used to cool down the skin area with a higher temperature, and various beauty effects such as cold compress and shrinking pores can be achieved.

[0033] In addition, in order to achieve the diversification of functions, a light outlet is provided on the action surface 11, and a window plate 4 is embedded in the light outlet for light emission. A light action module is provided in the housing 1 at a position corresponding to the window plate 4. The light action module can be selected to use various light action modules with cosmetic effects in the prior art, such as LED light action modules, strong pulse light action modules, laser action modules, etc. As needed, a light outlet and a window plate 4 are provided on the first action surface 111 and / or the second action surface 112. When the light outlet and the window plate 4 are provided for both the first action surface 111 and the second action surface 112, the window plates 4 in the housing 1 that match the first action surface 111 and the second action surface 112 can be provided with different light action modules, such as one of them is provided with a pulse light action module, and the other is provided with a laser action module. For example, when the eye area is acted on, the laser action module can emit a weak laser to stimulate the acupuncture points around the eyes, especially the Sikongzhu acupoint, the temple, the Cuanzhu acupoint, the Juliao acupoint, the Ashi acupoint, etc., to enhance the cosmetic effect of the eyes.

[0034] This beauty instrument is different from the beauty instrument in the prior art which has a large flat working surface. The working surface of this beauty instrument is set to be L-shaped, so that the flat part of the working surface can act on relatively flat areas such as the face and eyes, while the bent part can act on the curved surface and curved corners of the face, thereby ensuring that all areas of the face can be effectively acted on, taking into account the action requirements of different areas such as the face and eyes, and the action position is not limited.
