A beauty instrument is an instrument for regulating and improving skin conditions, which can help people to whiten, tenderize skin, remove spots and the like, and enables the skin to be tender, glossy, and elastic. The beauty instrument stimulates and acts on the skin by way of micro-frequency current, radio frequency, ultrasonic wave, and strong light, to improve skin metabolism, contract muscles, and realize a beauty function. It can also facilitate effective ingredients in skin care products to enter deep layers of the skin so as to be more easily absorbed and utilized by the skin, and function better in beautifying.
Electrodes may be provided on a care head of the beauty instrument to care for the skin by way of micro-frequency current or radio frequency. During operations of the beauty instrument, the electrodes on the care head are in contact with and discharges to the skin, thus realizing care effect. However, the electrodes on the care head are usually block electrodes with a large area, and a large interval is kept between the block electrodes to avoid short circuit. As a result, during care, users can obviously feel parts with the electrodes and those without the electrodes on the care head, thus the care experience is not good.

Referring to
In an embodiment, the operating part 100 includes a front housing 10, a rear housing 20, and a middle housing assembly 30. The front housing 10 and the rear housing 20 are respectively fixed to the middle housing assembly 30 from one side of two opposite sides of the middle housing assembly 30, to define an accommodation for accommodating internal electrical components such as circuits and wirings.
In an embodiment, the middle housing assembly 30 may be provided with a button (not shown) that can be operated and pressed by the user, so as to realize operations of switching functions of the beauty instrument or turning on and off of the power supply, or the middle housing assembly 30 may be provided with an indicator lamp that indicates an operation state of the beauty instrument.
With reference to
It can be understood that in this disclosure, the electrode is exposed on the main housing, which may include a situation that the electrode is convexly provided at a surface of the main housing, a situation that a surface of the electrode is flush with a surface of the main housing, or a situation that a groove is defined in the surface of the main housing, the electrode is accommodated in the groove, and the surface of the main housing protrudes from the surface of the electrode, as long as the electrode can discharge to the skin during contact between the housing and the skin.
In an embodiment, the operating part 100 is flat in shape, with a length direction perpendicular to its thickness direction. In the thickness direction of the operating part 100, each of the grip part 101 is arranged on flat surface at one side of both sides of the operating part 100. During using the beauty instrument, the user can hold the operating part 100 with one hand and push the beauty instrument back and forth along the length direction of the operating part 100 by holding the two grip parts 101. Since the extending direction Y of the first electrode 221 is basically perpendicular to the thickness direction X of the operating part 100, the first electrode 221 extends basically along the length direction of the operating part 100, so that when the beauty instrument is pushed along the skin surface, the length direction of the first electrode 221 is consistent with a moving direction of the beauty instrument, and the first electrode 221 moves on the skin surface along a pushing direction of the beauty instrument, which can reduce foreign body sensation on the skin surface of the user during operations of the beauty instrument and realize more comfortable care experience.
The operating part of the beauty instrument according to this embodiment is provided with an elongated first electrode. During use of the beauty instrument, the user holds the grip parts of the operating part and pushes the beauty instrument to move on the skin surface to perform skin care. Since the extending direction of the first electrode is basically perpendicular to the thickness direction of the operating part, the extending direction of the first electrode is consistent with the moving direction of the beauty instrument during movement of the beauty instrument, thus the user may not feel the foreign body sensation at care sites, and the elongated electrode ensures a contact area of the electrode with the skin, thus improving care efficiency and ensuring care experience. In this embodiment, a shape of the first electrode is provided to be matched with a setting of the grip part so as to guide the user to move the beauty instrument, thus fully using advantages of the strip electrode and improving the care efficiency and experience.
In an embodiment, the grip part 101 includes concave parts 101A formed on a side of the operating part 100, and each of the concave parts 101A may extend along the length direction of the first electrode 221. The grip part 101 can also be provided as a profiling concave part matched with a human hand. For example, the grip part 101 includes a first concave part corresponding to an arc contour of a human palm and a second concave part corresponding to a contour of a human knuckle. Due to provision of the profiling concave part, a contact area between a side surface of the operating part 100 and the human hand is increased, and the user can hold it more firmly.
In an embodiment, there may be more than one first electrode 221. As shown in
In an embodiment, the electrode assembly 220 further includes a plurality of dot electrodes 222 arranged at intervals, and at least part of the dot electrodes 222 are arranged in an array between the first sub-electrode 2211 and the second sub-electrode 2212, and an end of each of the dot electrodes 222 is exposed on an end 2101 of the main housing 210. The dot electrodes 222 are configured to perform skin care by generating micro current or radio frequency current.
In an embodiment, the electrode assembly 220 includes a plurality of rows of dot electrodes 222 arranged side by side, and two adjacent dot electrodes 222 among each row of dot electrodes 222 have opposite polarities and form an electrode pair. Illustratively, the electrode assembly 220 includes a plurality of rows of dot electrodes 222 arranged along the extending direction Y of the first electrode 221, and two adjacent dot electrodes 222 among each row of dot electrodes 222 have opposite polarities and form an electrode pair. When the two adjacent dot electrodes 222 among each row of dot electrodes 222 contact the skin at the same time, they can form a loop, thereby discharging to the skin. It can be understood that formation of electrode pairs of the dot electrodes 222 is not limited to this. For example, in other embodiments, two adjacent dot electrodes 222 in a direction perpendicular to the row of the dot electrodes 222 have opposite polarities and form an electrode pair.
In an embodiment, an area of each of the dot electrodes 222 is small, but there are a larger number of dot electrodes, and a cross section of the dot electrode 222 may be circular or elliptical. Illustratively, the dot electrodes 222 output a radio frequency current for skin care. In this embodiment, a large number of dot electrodes 222 are configured to contact with the skin, thus discharging to the skin. Compared with a method of using large-area electrodes for discharging, an effective contact area between the dot electrodes 222 and the skin is larger. For example, in areas with curvature such as mandible, the electrodes in array are more conducive to contact with the skin than the large-area electrodes. Moreover, due to decentralized arrangement of the dot electrodes 222, on a premise of a same electrode area, the decentralized electrodes have a larger skin action area than the large-area electrodes, with more uniform radio frequency energy distribution. It can be understood that in other embodiments, a micro current can also be output through the dot electrode 222 for the skin care.
In an embodiment, the main housing 210 includes an end 2101 and a side 2102. The electrodes at the end 2101 of the main housing 210 can discharge to the skin with flat area, and the electrodes at the side 2102 of the main housing 210 can discharge to the local skin. The first sub-electrode 2211 is arranged at the end 2101 of the main housing 210 and closing to a middle area of the end 2101 of the main housing, and the second sub-electrode 2212 is arranged at an edge of the end 2101 of the main housing 210 and partially extends to the side 2102 of the main housing 210. When the beauty instrument is pushed along the skin surface, the first sub-electrode 2211, the second sub-electrode 2212, and the dot electrodes 222 can serve to perform skin care for large flat area, for example, by generating a micro current to act on the skin to achieve skin resurfacing effect. The second sub-electrode 2212 can serve to perform care for an uneven skin surface. For example, the second sub-electrode 2212 may be in contact with an edge of the nose to discharge to the skin around the nose.
Illustratively, the first electrodes 221 include two second sub-electrodes 2212, with each second sub-electrode 2212 being located at one side edge of two side edges of the main housing 210 in the thickness direction X of the operating part 100. The first sub-electrode 2211 is arranged between the two second sub-electrodes 2212, and each of the two second sub-electrodes 2212 and the first sub-electrode 2211 have opposite polarities and form an electrode pair. When the first sub-electrode 2211 and a corresponding second sub-electrode 2212 are in contact with the skin at the same time, they can form a loop and thus discharge to the skin. The second sub-electrodes 2212 at the two sides can serve to respectively perform care for skin in different areas, thus expanding application scenarios. In addition, dot electrodes 222 may be arranged between the second sub-electrodes 2212 at the two sides and the first sub-electrode 2211 at the middle, and the dot electrodes 222 can cooperate with the first sub-electrode 2211 and the second sub-electrode 2212 of the first electrodes 221, so that the first sub-electrode 2211 and the second sub-electrode 2212 discharge to skin at an edge of a target area, while the dot electrodes 222 discharge to skin between the first sub-electrode 2211 and the first sub-electrode 2212, thus further expanding application scenarios and meeting care needs of different skin areas.
Because the two second sub-electrodes 2212 are respectively located at two side edges of the main housing 210 in the thickness direction X of the operating part 100, a distance between the second sub-electrode 2212 and the first sub-electrode 2211 can be maximized, so that a current sensation felt by the user is weakest during the second sub-electrode 2212 and the first sub-electrode 2211 are in contact with the skin and discharging, and thus comfort of care experience is improved to a maximum extent.
Illustratively, when it needs to achieve skin tightening effect for large-area skin, the beauty instrument can operate in a pulling mode and discharge to the large-area skin. For example, in this mode, the first electrode 221 and the dot electrode 222 output a radio frequency current at the same time, or the first electrode 221 outputs a micro current, or the first electrode 221 and the dot electrode 222 output a radio frequency current at the same time for a period of time and then the first electrode 221 outputs a micro current for a period of time, and these two manners are alternately adopted to discharge to the skin.
Illustratively, when it needs to perform care for skin in a nasolabial fold area, it can be achieved by cooperation of the first electrodes 221 and the dot electrodes 222. For example, the first electrode 221 and the dot electrode 222 can be combined and configured to alternately output the micro current and the radio frequency current, so that it is not easy for users to perceive change in current.
Illustratively, when it needs to perform care for skin in different areas, it can also be achieved by cooperation of the first electrodes 221 and the dot electrodes 222. For example, the first electrode 221 and the dot electrode 222 can be combined and alternately energized with a micro current and a radio frequency current, and after care for each area for a period of time, care can be performed for another care area, and in this process, it is not easy for users to perceive change in current.
In an embodiment, the electrode assembly 220 further includes a second electrode 223, and the second electrode 223 includes a first arc-shaped electrode 2231 and a second arc-shaped electrode 2232, which have opposite polarities and form an electrode pair. Illustratively, areas of the first arc-shaped electrode 2231 and the second arc-shaped electrode 2232 are both larger than that of the dot electrode 222. When the first arc-shaped electrode 2231 and the second arc-shaped electrode 2232 are in contact with the skin at the same time, they can form a loop and thus discharge to the skin.
In an embodiment, the first arc-shaped electrode 2231 is disposed at the edge of the end 2101 of the main housing 210 and partially extends to the side 2102 of the main housing 210, and the second arc-shaped electrode 2232 is disposed at the end 2101 of the main housing 210 and closing to the first arc-shaped electrode 2231. In this way, the first arc-shaped electrode 2231 and the second arc-shaped electrode 2232 of the second electrode 223 are located at the edge of the end 2101 of the main housing 210, and can be in contact with an uneven skin surface to discharge.
Illustratively, when it needs to perform care for skin at an eye area, it can be achieved by cooperation of the first arc-shaped electrode 2231 and the second arc-shaped electrode 2232 of the second electrode 223 to be in contact with the skin to discharge. For example, by alternately outputting a micro current and a radio frequency current by the first arc-shaped electrode 2231 and the second arc-shaped electrode 2232, it is not easy for users to perceive change in current.
In an embodiment, the second electrode 223 is disposed at an end of the first electrode 221 along the extending direction Y of the first electrode 221. For example, in the thickness direction X of the operating part 100, each of the two second sub-electrodes 2212 is arranged on one side of two sides of the main housing 210, and the first arc-shaped electrode 2231 and the second arc-shaped electrode 2232 are located between the two second sub-electrodes 2212 and at an end of the first sub-electrode 2211. The first arc-shaped electrode 2231 is further away from the first sub-electrode 2211 than the second arc-shaped electrode 2232.
In an embodiment, the first arc-shaped electrode 2231 and the second arc-shaped electrode 2232 extend in a same direction, and both of them are arched away from the first sub-electrode 2211. Both the first arc-shaped electrode 2231 and the second arc-shaped electrode 2232 extend towards both sides of the operating part 100 in the thickness direction X, that is, extend towards the two sides where the second sub-electrodes 2212 are located. When user moves the beauty instrument along the extending direction Y of the first electrode 221, length directions of the first arc-shaped electrode 2231 and the second arc-shaped electrode 2232 vertically intersect with the moving direction of the beauty instrument.
Illustratively, a connecting line of curvature centers of the first arc-shaped electrode 2231 and the second arc-shaped electrode 2232 is collinear with an extension line of the first sub-electrode 2211. Dot electrodes 222 may be also provided between the second arc-shaped electrode 2232 and the first sub-electrode 2211.
In an embodiment, an edge of the first electrode 221 is chamfered, for example, rounded or beveled; and/or both ends of the first electrode 221 in the longitudinal direction are arc-shaped. In this way, foreign body sensation caused by respective electrode of the electrode assembly 220 being in contact with the skin and moving on the skin surface can be further weakened. It can be understood that other electrodes of the electrode assembly 220 can be of similar structures. For example, edges of the dot electrodes 222 and the second electrode 223 can be chamfered, and both ends of the second electrode 223 in the length direction can also be arranged in an arc shape.
As shown in
The second ends of the dot electrodes 222 are limited by the end 2101 of the main housing 210, and the first ends of the dot electrodes 222 are abutted against the electrode contacts 231, so as to realize a passage between the dot electrodes 222, the circuit board 230, and human skin. When two adjacent dot electrodes 222 are in contact with the human skin at the same time, the two dot electrodes 222 form a loop, so as to discharge to the skin for care. Such construction of detachable dot electrodes 222 also facilitates replacement and maintenance of the electrodes.
In an embodiment, the performing part 200 further includes an insulating substrate 240, and each of the dot electrodes 222 penetrates through and is fixed to the insulating substrate 240. In this way, during installing the dot electrodes 222, the first ends of the dot electrodes 222 can be in contact with corresponding electrode contacts 231 on the circuit board 230 only by aligning and fixing the insulating substrate 240 to the main housing 210 and the circuit board 230. By integrating the dot electrodes 222 together using the insulating substrate 240, the dot electrodes 222 can be quickly disassembled and assembled, thus disassembling and assembling steps are simplified.
In an embodiment, the dot electrodes 222 and the insulating substrate 240 are integrally formed, for example, by injection molding, which simplifies a manufacturing process and improves assembly efficiency of the beauty instrument.
In an embodiment, the performing part 200 includes a circuit board 230 fixed in the main housing 210, and a plurality of lamp beads 232 are provided at a side of the circuit board 230 facing the electrode assembly 220. Correspondingly, a region of the main housing 210 facing the lamp beads 232 is allowed to be light-transmitting, and light emitted by the lamp beads 232 passes through the main housing 210 for skin care.
In an embodiment, the performing part 200 includes both the dot electrodes 222 and the lamp beads 232, and the lamp beads 232 are arranged among the dot electrodes 222. In the performing part 200 provided with the insulating substrate 240, the insulating substrate 240 can be made of a light-transmitting material, and light emitted by the lamp beads 232 passes through the insulating substrate 240 and then passes through the main housing 210, thereby performing skin care. In this way, the insulating substrate 240 can not only be used as a fixing medium for the dot electrodes 222, but also as a light-diffusing medium for the lamp beads 232, so that the light emitted from the lamp beads 232 to the human skin is more uniform and softer, thus realizing various functions.
In an embodiment, the performing part 200 of the beauty instrument includes:
a main housing 210;
an electrode assembly 220 provided and fixed to the main housing 210;
a circuit board 230 fixed in the main housing 210, a plurality of electrode contacts 231 being provided at a side of the circuit board 230 facing the electrode assembly 220; and
an insulating substrate 240.
The electrode assembly 220 includes a plurality of dot electrodes 222, each of the plurality of dot electrodes 222 penetrates through and is fixed to the insulating substrate 240. First ends of the plurality of dot electrodes 222 are abutted against the electrode contacts 231, and second ends of the plurality of dot electrodes 222 are exposed on the main housing 210 to discharge to skin.
Because the insulating substrate 240 integrates the dot electrodes 222 together, respective dot electrode 222 does not need to be mounted on the circuit board 230 or the main housing 210 one by one, but only needs to align the insulating substrate 240 to corresponding sites on the circuit board 230 or the main housing 210 and then complete relative fixation, and in this way, the respective dot electrode 222 can be in contact with the corresponding electrode contact 231 on the circuit board 230, thus eliminating cumbersome installation steps. Moreover, because the dot electrodes 222 are fixed to the insulating substrate 240, in case the dot electrodes 222 are damaged, it is only need to replace the insulating substrate 240, which improves convenience of maintenance.
In an embodiment, the dot electrodes 222 and the insulating substrate 240 are integrally formed, for example, by injection molding, which simplifies a manufacturing process and improves assembly efficiency of the beauty instrument.
In an embodiment, a plurality of lamp beads 232 are provided at a side of the circuit board 230 facing the electrode assembly 220, and the lamp beads 232 are arranged among the dot electrodes 222. The insulating substrate 240 is made of a light-transmitting material, and a region of the main housing 210 facing the lamp beads 232 is allowed to be light-transmitting. In this way, the insulating substrate 240 can not only be used as a fixing medium for the dot electrodes 222, but also as a light-diffusing medium for the lamp beads 232, so that the light emitted from the lamp beads 232 to the human skin is more uniform and softer, thus realizing various functions.

The first mounting groove T2 may provide an accommodating and limiting space for a part of the first sub-electrode 2211 located outside the main housing 210, and the first sub-electrode 2211 partially protrudes outside the first mounting groove T2 to contact the skin. The second through hole T3 and the third through hole T4 provide a space for the first fixing post T1 of the first sub-electrode 2211 to pass through, and the fourth through hole T5 provides a space for the first fastener S1 to pass through. Illustratively, the first fixing post T1 is a stud, and the first fastener S1 is threadedly connected with the first fixing post T1.

In an embodiment, the beauty instrument includes:
a main housing 210; and
an electrode assembly 220 provided in the main housing 210, the electrode assembly 220 including:
a plurality of elongated first electrodes 221, each of the plurality of elongated first electrodes 221 being exposed on the main housing 210, the plurality of elongated first electrodes 221 being arranged at intervals; and
a plurality of dot electrodes 222 arranged at intervals, at least part of the dot electrodes 222 being arranged between two adjacent first electrodes 221 in an array, an end of each of the dot electrodes 222 being exposed on the end 2101 of the main housing 210.
In this way, the elongated first electrodes 221 at the two sides are large-area electrodes that act on the skin to discharge, and the dot electrodes 222 between the elongated first electrodes 221 uniformly discharge to the skin on an area between the first electrodes 221, so that user is prevented from obviously feeling the electrode provision area on the care head, discharge uniformity is improved, a care area of the electrodes of the beauty instrument is increased, and care experience and efficiency are also improved. Further, different electrodes can act on the skin in different areas, thereby further expanding application scenes and meeting care needs of different skin areas.
Illustratively, the first electrodes 221 are parallel to each other. That is, extending directions of the first electrodes 221 are the same. When the beauty instrument moves along the skin surface, the elongated first electrodes 221 at the two sides are in contact with the skin at the same time, thus forming a loop and generating a current at a contact site with the skin, for example, a micro current or radio frequency current, to perform skin care.
It can be understood that in other embodiments, the first electrode 221 is not limited to be of a regular strip shape, and for example, the first electrode 221 can also be a wavy, zigzag, or multi-segment connected electrode.
In an embodiment, the first electrodes 221 include a first sub-electrode 2211 and a second sub-electrode 2212, and the first sub-electrode 2211 and the second sub-electrode 2212 have opposite polarities and form an electrode pair. At least part of the dot electrodes 222 are arranged between the first sub-electrode 2211 and the second sub-electrode 2212 in an array, thus filling a blank area between the first sub-electrode 2211 and the second sub-electrode 2212, thus performing care for a target skin area between the first sub-electrode 2211 and the second sub-electrode 2212, expanding a discharge area of the beauty instrument and improving care efficiency.
In an embodiment, the first sub-electrode 2211 is disposed at the end 2101 of the main housing 210 and closing to the middle area of the end 2101 of the main housing, the second sub-electrode 2212 is arranged at an edge of the end 2101 of the main housing 210, and the second sub-electrode 2212 at least partially extends to the side 2102 of the main housing 210.
During the process of the beauty instrument being pushed along the skin surface, the first sub-electrode 2211 and the dot electrodes 222 can serve to perform skin care on a large flat area, for example, by generating a micro current acting, to achieve skin resurfacing effect. The second sub-electrode 2212 can serve to perform care for an uneven skin surface. For example, the second sub-electrode 2212 can be in contact with an edge of the nose to discharge to skin around the nose.
In an embodiment, the first electrodes 221 include two second sub-electrodes 2212, each second sub-electrode 2212 is located at one side edge of two side edges of the main housing 210, the first sub-electrode 2211 is arranged between the two second sub-electrodes 2212, and each of the two second sub-electrodes 2212 and the first sub-electrode 2211 have opposite polarities and form an electrode pair.
When the first sub-electrode 2211 and a corresponding second sub-electrode 2212 at the two sides are in contact with the skin at the same time, they can form a loop and thus discharge to the skin. The second sub-electrodes 2212 at the two sides can perform care for skin in different areas, thus expanding application scenarios.
In an embodiment, dot electrodes 222 in an array are arranged between each of the second sub-electrodes 2212 and the first sub-electrode 2211. Thus, an area between the second sub-electrode 2212 on each side and the first sub-electrode 2211 at the middle can be filled with the dot electrodes 222 to discharge a target area between each of the second sub-electrodes 2212 and the first sub-electrode 2211.
In an embodiment, the electrode assembly 220 further includes a second electrode 223 disposed between the two second sub-electrodes 2212, and the second electrode 223 includes a first arc-shaped electrode 2231 and a second arc-shaped electrode 2232, which have opposite polarities and form an electrode pair. When the first arc-shaped electrode 2231 and the second arc-shaped electrode 2232 are in contact with the skin at the same time, they can form a loop and thus discharge to the skin.
In an embodiment, the first arc-shaped electrode 2231 is arranged at the edge of the end 2101 of the main housing 210, and the first arc-shaped electrode 2231 extends to the side 2102 of the main housing 210. In this way, the first arc-shaped electrode 2231 of the second electrode 223 is located at the edge of the end 2101 of the main housing 210, and can cooperate with the second arc-shaped electrode 2232 to be in contact with an uneven skin surface to discharge.
In an embodiment, the two second sub-electrodes 2212 and the second electrode 223 surround the dot electrodes 222. Therefore, a blank area among the second sub-electrode 2212, the first arc-shaped electrode 2231, and the second arc-shaped electrode 2232 (that is, an area without electrodes) can be filled by the dot electrodes 222, to allow the dot electrodes 222 to discharge to the skin, thus increasing care area.
In an embodiment, dot electrodes 222 are disposed between the edge of the end 2101 of the main housing 210 and at least one end of the first sub-electrode 2211 in a longitudinal direction. In this way, the blank area on a surface of the main housing 210 can be further reduced, thus increasing an effective care area of the beauty instrument.
The above are only specific embodiments of the present disclosure. It should be pointed out that some improvements and modifications can be made by those of ordinary skilled in the art without departing from technical principle of the present disclosure, which should also be regarded to be within a protection scope of the present disclosure.
