It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.

Referring to fig. 1, an embodiment of the present application provides a beauty treatment apparatus 1, where the beauty treatment apparatus 1 may be a radio frequency beauty treatment apparatus. The cosmetic instrument 1 includes at least a cosmetic head 10 and a handle 20 connected to each other.

The handle 20 may also be used as a support member for other components, such as the beauty head 10, and in addition, other components of the beauty instrument 1 may be installed inside the handle 20, so that the handle 20 may protect the internal components.

The beauty head 10 is a component of the beauty instrument 1 which plays roles of beauty, nursing and physiotherapy, and the beauty head 10 is connected with the handle 20 so that a user can conveniently move the beauty head 10 to various positions for beauty after holding the handle 20. In the present embodiment, the cosmetic head 10 is a radio frequency cosmetic head 10.

Referring to fig. 1-3, in some embodiments, cosmetic head 10 includes at least a housing 11, an insulator 12, and an electrode assembly 13.

The housing 11 is connected to the handle 20 for supporting the insulator 12, and the insulator 12 is indirectly mounted to the handle 20 through the housing 11. The housing 11 may be integrally formed with the handle 20 or may be separately provided, and when the housing 11 is separately provided with the handle 20, the housing 11 may be engaged with, screwed with, or bonded to the handle 20.

Referring to fig. 3, for example, the inner wall surface of the handle 20 is provided with a first protrusion 21 and a second protrusion 22 that are disposed opposite to each other, the protrusion height of the first protrusion 21 is higher than the protrusion height of the second protrusion 22, the housing 11 includes an elastic arm 111, the elastic arm 111 has a first slot 111a, the other side of the housing 11 opposite to the elastic arm 111 has a second slot 112a, the first protrusion 21 is snapped into the first slot 111a, the second protrusion 22 is snapped into the second slot 112a, the second protrusion 22 is snapped into the second slot 111a by the first protrusion 21, and the mating structure of the first protrusion 21 and the first slot 111a and the mating structure of the second protrusion 22 and the second slot 112a are disposed opposite to two opposite sides of the housing 11, so as to improve the stability of the housing 11 after being mounted on the handle 20. And the protruding height of the first protruding portion 21 is higher than the protruding height of the second protruding portion 22, the first clamping groove 111a is formed in the elastic arm 111, the elastic arm 111 is elastic, in the process of assembling the shell 11 to the handle 20, the second protruding portion 22 is clamped into the second clamping groove 112a, the elastic arm 111 is extruded through the first protruding portion 21, elastic deformation is caused to occur to the elastic arm 111, and then the first protruding portion 21 can be clamped into the first clamping groove 111a, so that the shell 11 can be assembled to the handle 20 simply.

Referring to fig. 1-3, the insulating member 12 has insulating properties, i.e., is non-conductive, the insulating member 12 is connected to the handle 20, the insulating member 12 and the housing 11 together form a mounting cavity 11a, the mounting cavity 11a has an opening 12a, the insulating member 12 is correspondingly disposed in the opening 12a, and other components of the cosmetic head 10, such as the electrode assembly 13, can be mounted in the mounting cavity 11 a. Further, the insulator 12 is exposed to the housing 11 so as to be adapted to be in direct contact with the skin of the user. The shape and material of the insulating member 12 may not be particularly limited, and in some embodiments, the insulating member 12 may be formed in a sheet shape, and the thickness of the insulating member 12 in the sheet shape may be thinner, so that the distance between other parts of the cosmetic head 10, such as the electrode assembly 13, and the skin in the mounting cavity 11a may be reduced, thereby improving the cosmetic effect.

Referring to fig. 3-4, the electrode assembly 13 is a main component for generating rf cosmetic effect, the electrode assembly 13 includes at least a first electrode 131 and a second electrode 132 spaced apart from each other and insulated from each other, and the electrode assembly 13 is mounted in the mounting cavity 11a, i.e. the first electrode 131 and the second electrode 132 are mounted in the mounting cavity 11 a.

In the related art, a resistor model is generally adopted to realize radio frequency beauty, that is, two radio frequency electrodes of a radio frequency beauty instrument are simultaneously contacted with skin of a user, when high-frequency alternating current is provided for the two radio frequency electrodes, current flows from one radio frequency electrode to the other radio frequency electrode through skin, through modeling, the skin can be equivalent to a resistor or a combination of the resistor and a capacitor, and the resistor has specific impedance, and continuous current directly penetrates through the skin surface layer through skin and radio frequency waves, so that the aim of heating collagen tissues and cell tissues is fulfilled, and the beauty effect is achieved.

Unlike the resistor model, the cosmetic device 1 of the embodiment of the present application implements radio frequency beauty treatment using the capacitor model, that is, is in direct contact with the skin through the insulating member 12, and the first electrode 131 and the second electrode 132 are disposed in the mounting cavity 11a, the insulating member 12 spacing the first electrode 131 and the second electrode 132 from the skin. When high-frequency alternating current is supplied to the first electrode 131 and the second electrode 132, a third electrode with opposite polarity to the first electrode 131 is induced by the skin of the part opposite to the first electrode 131, and the first electrode 131 and the third electrode are separated by the insulating member 12, and the whole can be equivalent to a capacitor; and the same is true. The portion of the skin opposite the second electrode 132 induces a fourth electrode of opposite polarity to the second electrode 132, the second electrode 132 being spaced from the fourth electrode by the insulator 12 and being equivalently another capacitance as a whole. Due to the direction to the first electrode 131

When alternating current is supplied to the second electrode 132, one of the first electrode 131 and the second electrode 132 is positive, and the other is negative, and thus the limits of the third electrode and the fourth electrode are also opposite, current flows from the third electrode as the positive electrode to the fourth electrode as the negative electrode, or from the fourth positive electrode as the positive electrode to the third electrode as the negative electrode, and an induced current is induced between the third electrode and the fourth electrode.

In addition, the skin is divided into a basal layer, a thorn layer, a particle layer and a transparent layer from inside to outside

And the stratum corneum, which is a barrier that reduces the passive diffusion of 0% of water from the skin, while acting to prevent other molecules (including irritants) from entering the skin

Is a barrier to the passage of water. The skin barrier is formed primarily by the attachment of keratinocytes and intercellular lipids and other structures

The "brick wall" structure, the tight junctions of keratinocytes and intercellular lipids, are critical to maintaining the integrity of the skin barrier. There are studies showing that: the main cause of sensitive muscles is an impaired skin barrier function, i.e. "brick

Wall "structural weakness or imperfections. On the one hand, the skin barrier function is impaired, the percutaneous loss of moisture is accelerated 5 times and the loss of skin nutrients is accelerated, wherein the ceramide content is remarkably reduced, and the ceramide content is simultaneously matched with the skin

The level of sphingolipids associated with decreased barrier stability is up-regulated; on the other hand, the fragile skin barrier can enhance the penetration of irritants or allergens, the nerve endings are not fully protected, and deeper skin is exposed to microorganisms and external stimulus, thereby inducing local inflammatory states of the skin, and generating redness, itching and burning thorns

Pain, etc. And studies have shown that: the impaired skin barrier integrity increases the incidence of atopic dermatitis by a few 0 times, and the risk of allergy in individuals with sensitive skin is also 5 times higher.

The induced current in the embodiment of the application can generate heat when flowing in the skin, thereby accelerating the aging cell apoptosis, inducing the proliferation and differentiation of the granulosa layer cells, forming the horny layer with a brick wall structure after the cell apoptosis, thickening and densification of the horny layer, playing the role of repairing skin barriers, improving sensitive muscles,

simultaneously promote the regeneration of collagen in dermis, effectively lock moisture, make skin become compact, and improve wrinkles. In some embodiments, in order to better generate an induced current on the skin, the thickness D of the insulating member 12 is greater than or equal to 0.4mm, and the distance between the first electrode 131 and the second electrode 132 and the skin is also greater than or equal to at least 0.4mm, so that the portion of the skin opposite to the first electrode 131 senses the third electrode, the portion of the skin opposite to the second electrode 132 senses the fourth electrode, and further, an induced current is generated between the third electrode and the fourth electrode, and the first electrode 131 and the second electrode 132 are not in direct contact with the skin, so that the user is prevented from being scalded by the first electrode 131 and the second electrode 132. When the thickness D of the insulating member 12 is less than 0.4mm, the capacitor model cannot be formed between the first electrode 131 and the second electrode 132 and the skin, and thus the capacitor model fails, and the cosmetic effect cannot be achieved.

It will be appreciated that in other embodiments, it is only necessary to ensure that the distance from the side of the first electrode 131 and the second electrode 132 facing the insulating member 12 to the side of the insulating member 12 for contacting the skin of the human body is greater than or equal to 0.4mm, so that the electrode assembly 13 can construct a capacitor model with the skin of the human body. At this time, the thickness D of the insulator 12 has no direct relation with the establishment of the capacitor model. However, the insulation member 12 directly defines the distance between the electrode assembly 13 and the skin of the human body, so that the structure is simpler and the implementation is easier.

Referring to fig. 3, in some embodiments, the side surface of the first electrode 131 facing the insulating member 12 is bonded to the inner side surface of the insulating member 12 facing the mounting cavity 11a, the side surface of the second electrode 132 facing the insulating member 12 is bonded to the inner side surface of the insulating member 12 facing the mounting cavity 11a, so that the side surface of the first electrode 131 and the second electrode 132 facing the insulating member 12 is bonded to the inner side surface of the insulating member 12 facing the mounting cavity 11a on the basis that the thickness D of the insulating member 12 can ensure the effectiveness of the capacitor model of the electrode assembly 13, the distances between the first electrode 131 and the second electrode 132 and the skin can be reduced, the first electrode 131 and the second electrode 132 can be made to be as close to the skin as possible, the induced current generated between the third electrode and the fourth electrode is relatively large under the same skin depth condition, and the skin repair effect can be improved and the energy utilization rate can be improved under the condition that the shortwave frequency and the working voltage of the high-frequency alternating current are relatively low. Conversely, when the first electrode 131 and the second electrode 132 are not bonded to the insulating material 12, the distance between the first electrode 131 and the second electrode 132 and the skin increases, and in order to achieve the same repairing effect, it is necessary to increase the frequency and/or voltage of the high-frequency alternating current supplied to the first electrode 131 and the second electrode 132, and the energy utilization rate is low.

In some embodiments, the thickness D of the insulating member 12 is less than or equal to 3mm, so that the distance between the first electrode 131 and the second electrode 132 and the skin is relatively short, and the induced current generated between the third electrode and the fourth electrode is relatively large under the condition of the same skin depth, so that the skin repair effect and the energy utilization rate can be improved under the condition of relatively low shortwave frequency and working voltage of the high-frequency alternating current. On the contrary, when the thickness D of the insulating member 12 is greater than 3mm, it is necessary to increase the shortwave frequency and the operating voltage of the high-frequency alternating current supplied to the first electrode 131 and the second electrode 132 in order to achieve the same skin repair effect, and the energy utilization rate is low.

By way of example, the thickness D of the insulator 12 may be 0.4mm, 1mm, 2mm, 3mm, etc. The thickness D of the insulating member 12 is preferably equal to 0.4mm, and the thickness D of the insulating member 12 is relatively thin, so that the electrode assembly 13 is relatively close to the skin of the human body, and further, the energy radiated by the electrode assembly 13 is more introduced into the skin of the human body, so that the utilization rate of radio frequency energy can be improved. When the thickness D of the insulating member 12 is equal to 1mm or 2mm, the thickness D of the insulating member 12 is relatively moderate, so that the electrode assembly 13 can be ensured to construct a capacitor model with human skin, the electrode assembly 13 is relatively close to the human skin, and the utilization rate of radio frequency energy of the electrode assembly 13 can be improved. At a thickness D of the insulator 12 equal to 3mm, the distance between the electrode assembly 13 and the human skin is sufficiently large to ensure that the electrode assembly 13 and the human skin establish a capacitor model.

In some embodiments, the insulating member 12 is detachably connected to the housing 11, the number of insulating members 12 is plural, the plurality of insulating members 12 are alternatively connected to the housing 11, at least two of the plurality of insulating members 12 are different in thickness, that is, by detachably connecting the insulating members 12 to the housing 11, the insulating members 12 of different thicknesses may be assembled to the housing 11, and the electrode assemblies 13 are spaced apart from the skin by different distances corresponding to the insulating members 12 of different thicknesses, so that the electrode assemblies 13 may act on the skin of different depths, for example, when the insulating members 12 are thinner, the electrode assemblies 13 are spaced apart from the skin by a smaller distance, the electrode assemblies 13 may act on deeper granular layers, and when the insulating members 12 are thicker, the electrode assemblies 13 are spaced apart from the skin by a larger distance, the electrode assemblies 13 may act on the shallower stratum corneum, thereby improving the skin location of different depths with pertinence. It will be appreciated that. The removable connection of the insulator 12 to the housing 11 includes, but is not limited to, a snap fit connection, a threaded connection, or a magnetically attractive connection.

In some embodiments, the housing 11 extends along a first direction a, which is parallel to the length direction of the handle 20 and points from the handle 20 to the beauty head 10, and the insulator 12 is provided on one side of the housing 11 along the first direction a, so that the insulator 12 can be exposed to the housing 11 for direct contact with the skin.

Further, the insulating member 12 is in sealing connection with the housing 11, so that not only can dust and water be prevented, but also when the beauty instrument 1 is matched with gel for beauty treatment, the gel can be prevented from entering the mounting cavity 11a through a gap between the insulating member 12 and the housing 11, and further, the first electrode 131 and the second electrode 132 are prevented from being short-circuited by the gel, and the first electrode 131 and the second electrode 132 are prevented from being invalid due to short circuit.

Referring to fig. 1, further, the insulating member 12 is disposed in the middle of the housing 11, so that a certain distance is provided between the insulating member 12 and the edge of the housing 11, and when the cosmetic device 1 is inadvertently dropped, if the cosmetic head 10 is downward, the insulating member 12 collides with the ground, so that the probability of breaking the insulating member 12 due to the dropping of the cosmetic device 1 can be reduced.

In some embodiments, the insulating member 12 is in a one-piece structure, no gap exists in the middle of the insulating member 12, and the surface of the insulating member 12 used for contacting the skin is a plane or a smooth curved surface, that is, the surface of the insulating member 12 used for contacting the skin does not have a step structure, a groove or an opening, etc., so when the beauty instrument 1 cooperates with liquid such as gel to make beauty, the liquid such as gel can be prevented from entering the gap or the step structure, the groove or the opening, which is convenient for cleaning the liquid such as gel, and the liquid such as gel can be prevented from entering the installation cavity 11a through the gap, the groove or the through hole, and further, the electronic circuit such as the electrode assembly 13 in the installation cavity 11a can be prevented from being shorted.

Referring to fig. 2, in some embodiments, the cosmetic apparatus 1 further includes a circuit board 14, the circuit board 14 is disposed in the handle 20, and the circuit board 14 is used to control the operation of various electronic devices of the cosmetic apparatus 1 to implement the cosmetic function. The circuit board 14 may be a printed circuit board, a flexible circuit board, or a rigid-flex board.

In order to realize the rf function of the electrode assembly 13, the circuit board 14 includes a short-wave rf generator (not shown in the figure), which is disposed in the handle 20 or the housing 11, and the short-wave rf generator is electrically connected to the first electrode 131 and the second electrode 132, and can provide high-frequency ac power to the first electrode 131 and the second electrode 132 through the short-wave rf generator, and excite the rf signals, and the first electrode 131 and the second electrode 132 can convert the rf signals into electromagnetic waves and act on human tissues, thereby achieving the purpose of beauty, that is, achieving the rf beauty function of the first electrode 131 and the second electrode 132. Specifically, since the electrode assembly 13 is insulated from the skin of the human body by the insulating member 12, the electrode assembly 13 can construct a capacitor model with the skin of the human body when the short-wave radio frequency generator is operated, that is, when a radio frequency signal is supplied to the electrode assembly 12.

In some embodiments, the working voltage of the high-frequency alternating current provided by the short-wave rf generator to the electrode assembly 13 is greater than or equal to 90V, and the short-wave frequency of the high-frequency alternating current provided by the short-wave rf generator to the electrode assembly 13 is 6.78MHz, 13.56MHz, 27.12MHz, 40.68MHz or 54.24MHz, that is, the short-wave rf generator of the rf transmitter transmits the rf signal with the frequency of 6.78MHz, 13.56MHz, 27.12MHz, 40.68MHz or 54.24MHz through the electrode assembly 13, and the voltage is greater than or equal to 90V, so that the working voltage of the electrode assembly 13 is higher, and the short-wave frequency of the radiation energy of the electrode assembly 13 is higher, so that a larger induction current can be induced at a deeper skin position, providing a larger repair energy, and further improving the repair effect.

As can be seen from the above description, when the electrode assembly 13 performs the rf operation, the short-wave frequency of the high-frequency ac power supplied to the first electrode 131 and the second electrode 132 is very high, for example, when the short-wave frequency of the high-frequency ac power is 27.12MHz, the current direction of the high-frequency ac power is changed by 2712 ten thousand times within 1 second, so that the high-frequency ac power is liable to break down between the first electrode 131 and the second electrode 132, resulting in short circuit between the first electrode 131 and the second electrode 132, which may cause the problems of skin scald, damage to the cosmetic instrument 1, etc. in serious cases.

In order to solve the problem that the first electrode 131 and the second electrode 132 may be broken down by high-frequency ac power, in some embodiments, the first electrode 131 and the second electrode 132 have a first distance D1 therebetween, and the first distance D1 is 1.5mm or more and 5mm or less, and the applicant has found that by setting the first distance D1 to 1.5mm or more, breakdown is less likely to occur between the first electrode 131 and the second electrode 132, thereby making the cosmetic instrument 1 more stable and safer to operate. When the first distance D1 is less than 1.5mm, the probability of breakdown between the first electrode 131 and the second electrode 132 will be greatly increased.

Further, the first distance D1 is 2mm or more. Although it is theoretically required that the first distance D1 between the first electrode 131 and the second electrode 132 is 1.5mm or more, that is, the risk of breakdown of the first electrode 131 and the second electrode 132 can be greatly reduced, after the first electrode 131 and the second electrode 132 are actually mounted, the first distance between the first electrode 131 and the second electrode 132 in the partial region is less than 1.5mm due to the mounting inaccuracy, that is, the assembly inaccuracy, and therefore, the breakdown phenomenon is liable to occur, and therefore, by limiting the first distance D1 to 2mm or more, even if the mounting inaccuracy exists, the first distance D1 is 1.5mm or more after the first electrode 131 and the second electrode 132 are mounted, and further, the breakdown phenomenon is not liable to occur between the first electrode 131 and the second electrode 132. When the first distance D1 is less than or equal to 5mm, the overall size of the electrode assembly 13 can be reduced, thereby facilitating the reduction of the overall size of the cosmetic head 10, when the skin of the user is actually beautified, not planar, but there are some corner regions including skin depressions such as eyelets and skin protrusions such as noses, the smaller cosmetic head 10 can be more closely attached to the depressions of the skin, thereby achieving better cosmetic effect, and the smaller cosmetic head 10 can attach the vast majority of the insulator 12 to the skin, thereby enabling more rf energy to act on the skin, and improving energy utilization. When the first distance D1 is greater than 5mm, the cosmetic head 10 will be larger, a part of the cosmetic head 10 cannot contact with the skin, the energy radiates into the air, resulting in a reduction in energy utilization, and when the skin depression is required to be beautified, the cosmetic head 10 cannot be conveniently attached to the skin depression or near the skin depression, resulting in a reduction in the cosmetic effect on the skin depression.

Illustratively, the first spacing D1 may be 1.5mm, 2mm, 3mm, 5mm, etc. When the first distance D is equal to 1.5mm, the first distance D1 is small, so that the overall size of the beauty head 10 can be reduced, on the basis that the probability of breakdown of the first electrode 131 and the second electrode 132 can be reduced. The first distance D1 is preferably equal to 2mm or 3mm, and it is possible to avoid the first electrode 131 and the second electrode 132 from being broken down due to the assembly error, which results in the first electrode 131 and the second electrode 132 having a distance of less than 1.5 mm. At the first distance D1 equal to 5mm, the distance between the first electrode 131 and the second electrode 132 is sufficiently large to ensure that no breakdown phenomenon necessarily occurs between the first electrode 131 and the second electrode 132.

Referring to fig. 4, in some embodiments, the first electrode 131 is in a sheet shape, the second electrode 132 is in a ring shape, and the second electrode 132 is disposed around the first electrode 131, so that the assembly compactness of the first electrode 131 and the second electrode 132 can be improved, and the occupied area of the first electrode 131 and the second electrode 132 can be increased in the same assembly area, thereby improving the rf effect; in addition, by arranging the second electrode 132 in a ring shape, even if only the portion of the second electrode 132 is opposite to the skin when the skin is covered and beautified, the fourth electrode can be induced on the skin to construct a capacitor model, thereby improving the beauty effect of sensitive muscles and the like.

As shown in fig. 4, in some embodiments, the first electrode 131 is in a circular shape, the second electrode 132 is in a circular shape, and the second electrode 132 is disposed around the first electrode 131 and is concentric with the first electrode 131, so that each position of the first electrode 131 is equal to the first distance D1 of the second electrode 132 in the radial direction, and there is no situation that the first distance D1 is too large in some positions and the first distance D1 is too small in other positions, resulting in breakdown between the first electrode 131 and the second electrode 132.

In other embodiments, the first electrode 131 is in a triangular plate shape, the second electrode 132 is in a triangular ring shape, and the second electrode 132 is disposed around the first electrode 131 and is concentric with the first electrode 131, so that each position of the first electrode 131 is substantially equal to the first distance D1 of the second electrode 132 in the radial direction, and there is no situation that the first distance D1 corresponding to different positions is too different, resulting in the first distance D1 being smaller than 1.5mm, and the first electrode 131 and the second electrode 132 are prevented from breakdown.

In still other embodiments, the first electrode 131 is Fang Pianzhuang, the second electrode 132 is square, and the second electrode 132 is disposed around the first electrode 131 and is concentric with the first electrode 131, so that each position of the first electrode 131 is substantially equal to the first spacing D1 of the second electrode 132 in the radial direction, and there is no situation that the first spacing D1 corresponding to different positions is too different, resulting in the first spacing D1 being smaller than 1.5mm, and breakdown between the first electrode 131 and the second electrode 132 can be avoided. It is understood that the first electrode 131 may have other sheet structures, and the second electrode 132 may have other ring structures.

In other embodiments, the first electrode 131 and the second electrode 132 are arc-shaped, the concave side edge of the arc-shaped first electrode 131 is opposite to the concave inner side edge of the arc-shaped second electrode 132, the arc-shaped first electrode 131 and the arc-shaped second electrode 132 may be disposed on the same circle or may be disposed on different circles, and when the arc-shaped first electrode 131 and the arc-shaped second electrode 132 are disposed on the same circle, the effect similar to the above-mentioned annular second electrode 132 can be achieved, that is, when skin is covered and beautified, even if only the portions of the first electrode 131 and the second electrode 132 are opposite to the skin, the third electrode and the fourth electrode are respectively induced on the skin, so as to construct a capacitor model, thereby playing the role of improving the sensitive muscle.

Further, the beauty apparatus 1 further comprises at least a first wire (not shown in the figure) and a second wire 133, wherein the first wire is connected to the short-wave rf generator and the first electrode 131, the second wire 133 is connected to the short-wave rf generator and the second electrode 132, in the embodiment where the second electrode 132 is configured to be annular and configured to be disposed around the first electrode 131, the first wire needs to be electrically connected to the first electrode 131 across the annular second electrode 132, and in the embodiment where the first electrode 131 and the second electrode 132 are configured to be arc-shaped, the first wire can be connected to the first electrode 131 without crossing the second electrode 132, so that the connection is more convenient.

In some embodiments, the area of at least one of the first electrode 131 and the second electrode 132 is less than or equal to 6cm2, so that the overall size of the electrode assembly 13 can be reduced, thereby being beneficial to reducing the overall size of the cosmetic head 10, and in actual beauty, the smaller cosmetic head 10 can be more tightly attached to the concave portion of the skin, thereby achieving better beauty effect, and the smaller cosmetic head 10 can attach the vast majority of the insulating member 12 to the skin, thereby enabling more rf energy to act on the skin, and further improving energy utilization. When the areas of the first electrode 131 and the second electrode 132 are both larger than 6cm2, the cosmetic head 10 is larger, the partial area of the cosmetic head 10 cannot be contacted with the skin, the energy utilization rate is reduced, and when the skin is required to be beautified, the cosmetic head 10 cannot be conveniently attached to or near the skin recess, so that the beautifying effect of the skin recess is poor.

Referring to fig. 2, in some embodiments, a distance D2 between the electrode assembly 13 and the outer circumferential surface of the case 11 is 2mm or more and 8mm or less, which facilitates the installation of the electrode assembly 13 into the installation cavity 11a, and does not make the cosmetic head 10 too large to cause a reduction in the cosmetic effect on the skin depression. When the distance D2 between the electrode assembly 13 and the outer circumferential surface of the case 11 is less than 2mm, the electrode assembly 13 may interfere with the cavity wall of the mounting cavity 11a, and it is inconvenient to mount the electrode assembly 13. The distance D2 between the electrode assembly 13 and the outer circumferential surface of the case 11 is greater than 8mm, and a large area between the electrode assembly 13 and the case 11 does not play a cosmetic role, but results in a larger cosmetic head 10, resulting in a reduced cosmetic effect on the skin depression.

Illustratively, the distance D2 between the electrode assembly 13 and the outer circumferential surface of the case 11 may be equal to 2mm, 3mm, 5mm, 6mm, 8mm, etc. When the distance D2 between the electrode assembly 13 and the outer circumferential surface of the case 11 is equal to 2mm, the distance D2 between the electrode assembly 13 and the outer circumferential surface of the case 11 is relatively short, and the size of the cosmetic head 10 can be reduced, which is advantageous for cosmetic treatment of the skin corner. The distance D2 between the electrode assembly 13 and the outer circumferential surface of the case 11 is preferably equal to 3mm, 5mm or 6mm, not only enabling the cosmetic head 10 to have a smaller size, but also enabling the electrode assembly 10 to be more conveniently housed in the case 11, i.e., assembly to be simpler. The distance D2 between the electrode assembly 13 and the outer circumferential surface of the case 11 is equal to 8mm, and the distance D2 between the electrode assembly 13 and the outer circumferential surface of the case 11 is sufficiently large not only to facilitate the easy installation of the electrode assembly 10 into the case 11, but also to form a gap between the electrode assembly 13 and the inner wall of the case 11, which allows other components of the cosmetic head 10 (for example, a light emitting assembly 19 described below) to be mounted, so that the cosmetic head 10 is more compact in structure, and the cosmetic head 10 is not oversized.

In some embodiments, the cosmetic apparatus 1 further has a skin temperature control function of the insulating member 12, referring to fig. 3, the cosmetic apparatus 1 further includes a heat exchange assembly 15, the heat exchange assembly 15 is located in the mounting cavity 11a and is disposed corresponding to the insulating member 12, and the heat exchange assembly 15 is used for exchanging heat with the insulating member 12, so that the cosmetic apparatus 1 can perform cold compress or hot compress on the skin of a user, and can maintain a required specific temperature during the cold compress or hot compress. Illustratively, the cold compress temperature of the insulating member 12 is lower than 24 degrees, which can relieve pain and swelling of skin, and the hot compress temperature of the insulating member 12 is higher than 30 degrees, which can accelerate blood circulation and promote cell regeneration.

Referring specifically to fig. 2-3, heat exchange assembly 15 includes a heat exchange member 16 disposed within mounting cavity 11 a. It will be appreciated that the heat exchange member 16 may be disposed in the handle 20, or a portion of the heat exchange member 16 may be disposed in the mounting cavity 11a, and the rest may be disposed in the handle 20, so that the mounting position of the heat exchange member 16 in the cosmetic apparatus 1 may be adjusted according to the actual mounting requirement of the heat exchange member 16. The heat exchanging member 16 is electrically connected to the circuit board 14, and is used for cooling or heating the insulating member 12 under the control of the circuit board 14. The heat exchange member 16 may have only the cooling or heating function, or may have both the above functions. Illustratively, the heat exchange member 16 may be a semiconductor refrigeration sheet having both of the above functions.

In some embodiments, the heat exchange member 16 may directly abut against the inner side surface of the insulating member 12 to directly transfer heat or cold to the insulating member 12, so as to adjust the skin temperature of the insulating member 12, and the heat exchange member 16 may also indirectly transfer heat or cold to the insulating member 12 through other heat conducting media. In some embodiments, the heat exchange assembly 15 further includes a heat conducting member 17, where the heat conducting member 17 is disposed in the mounting cavity 11a and abuts against an inner side surface of the insulating member 12, the heat conducting member 16 abuts against a surface of the heat conducting member 17 facing away from the electrode assembly 13, and the heat conducting member 17 can transfer heat or cold of the heat conducting member 16 to the insulating member 12 through the heat conducting member 17, so as to realize temperature adjustment of the insulating member 12.

Because the electrode assembly 13 is attached to the inner side surface of the insulating member 12, compared with the case that the heat exchange member 16 is directly abutted to the inner side surface of the insulating member 12, the heat or cold of the heat exchange member 16 is transferred to the insulating member 12 through the heat conducting member 17 as an intermediate medium, the positions of the heat exchange member 16 and the heat conducting member 17 can be reasonably adjusted according to actual needs, for example, the positions of the insulating member 12, the electrode assembly 13, the heat conducting member 17 and the heat exchange member 16 can be sequentially arranged along the outer-inner direction of the insulating member 12, so that the insulating member 12, the electrode assembly 13, the heat conducting member 17 and the heat exchange member 16 are equivalent to being sequentially arranged on the central axis of the insulating member 12, but not on different axes, thereby forming a staggered arrangement, and reducing the radial dimension (or transverse dimension) of the whole body formed by the insulating member 12, the electrode assembly 13, the heat conducting member 17 and the heat exchange member 16 in the radial direction of the handle 20 on the basis that the cosmetic head 10 is ensured to have a radio frequency cosmetic function and an attaching temperature control function, and the cosmetic head 10 can be more beneficial to skin care.

Further, the heat conductive member 17 has deformability, and the heat conductive member 17 is an elastic heat conductive member 17. The elastic heat conducting piece 17 is arranged between the insulating piece 12 and the heat exchanging piece 16 and is respectively in contact with the insulating piece 12 and the heat exchanging piece 16, and the heat exchanging piece 16 is in heat transfer connection with the insulating piece 12 through the elastic heat conducting piece 17, so that the heat exchanging piece 16 transfers heat or cold to the insulating piece 12 through the elastic heat conducting piece 17, and the skin temperature of the insulating piece 12 is controlled. The elastic heat conductive member 17 may be, for example, a heat conductive silicone.

Referring to fig. 2-3, in some embodiments, the electrode assembly 13 is disposed between the elastic heat conducting member 17 and the insulating member 12, that is, the electrode assembly 13 is sandwiched between the heat exchanging member 15 and the light-transmitting insulating member 12, and the elastic heat conducting member 17 presses the electrode assembly 13 to attach the electrode assembly 13 to the inner side surface of the insulating member 12, so that the electrode assembly 13 has a smaller distance from the skin when the electrode assembly is opposite to the skin through the insulating member 12, and thus more rf energy can enter the skin, thereby improving the cosmetic effect. And when the insulating member 12 is slightly deformed by skin extrusion, the elastic heat conducting member 17 can buffer the extrusion force of the insulating member 12 to the electrode assembly 13, and compress the electrode assembly 13 on the inner side surface of the insulating member 12 by the elastic restoring force of the elastic heat conducting member.

Referring to fig. 5, further, the elastic heat conducting member 17 has a grooved surface 151 disposed towards the insulating member 12, the grooved surface 151 is provided with a fixing groove 15a, the first electrode 131 and the second electrode 132b are mounted in the fixing groove 15a, and the first electrode 131 and the second electrode 132 partially protrude from the grooved surface 151, so that after the first electrode 131 and the second electrode 132 are mounted in the fixing groove 15a, the insulating member 12 is mounted on the housing 11, the first electrode 131 and the second electrode 132 are pressed in the fixing groove 15a, and the elastic heat conducting member 17 has elastic restoring force, so that the first electrode 131 and the second electrode 132 are closely attached to the inner side surface of the insulating member 12, and the first electrode 131 and the second electrode 132 are in zero clearance fit with the inner side surface of the insulating member 12, so that the electrode assembly 13 has a smaller distance from the skin when passing through the insulating member 12, thereby enabling more rf energy to enter the skin, improving the energy utilization rate, and improving the beauty effect. It is understood that the first electrode 131 and the second electrode 132 may be mounted in the same fixing groove 15a, or may be mounted in different fixing grooves 15a in a one-to-one correspondence.

Conversely, when the first electrode 131 and the second electrode 132 are not attached to the inner side surface of the insulating member 12, the first electrode 131 and the second electrode 132 are farther from the inner side surface of the insulating member 12, which corresponds to the electrode assembly 13 being farther from the skin, the distance between the first electrode 131 and the third electrode in the capacitance model is increased, the distance between the second electrode 132 and the fourth electrode is also increased, and the induced current generated between the third electrode and the fourth electrode is smaller at the same skin depth, resulting in a decrease in skin repair effect, or a larger shortwave frequency and operating voltage are required to achieve the same skin repair effect, resulting in a lower energy utilization rate.

Further, in order to better control the skin temperature of the insulating member 12, the device further comprises a temperature sensor (not shown in the figure), wherein the temperature sensor is arranged in the mounting cavity 11a and is positioned at one side of the insulating member 12 and is used for detecting the temperature of the insulating member 12 and is electrically connected with the circuit board 14, the temperature sensor sends a detected temperature signal of the insulating member 12 to the circuit board 14, and the circuit board 14 controls the heat exchange member 16 to work according to the temperature signal, so that the heat exchange member 16 is controlled to perform refrigeration or heating work, or when the temperature of the insulating member 12 reaches a preset temperature to be maintained, the heat exchange member 16 is controlled to stop working, so that skin scalding caused by overhigh temperature of the insulating member 12 can be avoided, skin damage caused by overlow temperature of the insulating member 12 can be avoided, and the radio frequency beautifying effect of the electrode assembly 13 is influenced. How skin damage is caused and the radio frequency cosmetic effect of the electrode assembly 13 is affected when the temperature of the insulating member 12 is too low is described as follows:

Studies have shown that when skin temperature is 15 ℃, skin vasoconstriction reaches a maximum, tissue damage can be caused by long-term maintenance of tissue temperature at 15 ℃, and nerve damage can be caused below 15 ℃. According to van der waals' law, cryotherapy, i.e. cold compress, reduces biochemical reactions in time units, thereby slowing down cellular metabolism. The first modification of the vascular system involves surface vasoconstriction followed by reflex systemic vasoconstriction. Vasoconstriction is greatest at 15 ℃. When the skin temperature drops by 15 ℃, contradictory vasodilation occurs due to paralysis of vascular smooth muscle or nerve block of vasoconstrictive nerve fibers. This vasodilation is a defensive mechanism to maintain blood flow at low temperatures. Low temperatures slow down peripheral nerve conduction. It has been shown that for every 1℃decrease in temperature, the peripheral nerve conduction decreases by 2.4m/s and that at 10℃to 15℃the nerve conduction completely disappears. The effect of cryotherapy on muscle is related to the time of application. When the cryotherapy local temperature is below about 14 ℃, the propagation of action potentials along the autonomic and sensory nerves is impaired (cold-induced nerve loss), leading to contradictory vasodilation and paresthesia. In the embodiment of the application, the target temperature of cold compress is in a 15-25 ℃ range from the safety point of view, the cold compress time is about 30min, and the cold compress time can be monitored in real time through a temperature sensor, so that the safety is ensured; if the temperature is selected in the range of 0-10 ℃, the corresponding cosmetic duration should be considered, so as to avoid nerve damage and discomfort caused by cryotherapy.

Further, in order to make the heat exchange member 16 better radiate the corresponding heat during the operation, referring to fig. 2-3, the heat exchange assembly 15 further includes a heat dissipation member 18, the heat dissipation member 18 abuts against a side of the heat exchange member 16 facing away from the heat conducting member 17, that is, the heat exchange member 16 is located between the heat conducting member 17 and the heat dissipation member 18, and the heat exchange member 16 abuts against or abuts against the heat conducting member 17 and the heat dissipation member 18 at the same time, so as to realize heat transfer connection.

When the heat exchange piece 16 carries out refrigeration work, can be through heat conduction piece 17 with the cold volume transfer give insulating part 12 better, namely heat exchange assembly 15 is used for transmitting the cold volume to printing opacity insulating part 12, realize the cold compress function of insulating part 12, simultaneously, heat exchange piece 16 passes through heat dissipation piece 18 with the heat that heat exchange piece 16 produced in the inside air of handle 20 or handle 20, and in with the heat transfer outside air through handle 20, avoid the heat to cause too big influence to the refrigeration work of heat exchange piece 16, guarantee that heat exchange piece 16 can high-efficient work, and can avoid the heat transfer to the insulating part 12 place one side, avoid the heat to cause the influence to the cold compress effect of this insulating part 12.

Similarly, when the heat exchange piece 16 heats, heat can be better transferred to the insulating piece 12 through the heat conducting piece 17, the hot compress function of the insulating piece 12 is realized, simultaneously, cold produced by the heat exchange piece 16 is quickly transferred to the handle 20 or the inside air of the handle 20 through the heat radiating piece 18, and the cold is transferred to the outside air through the handle 20, so that the excessive influence of the cold on the heating work of the heat exchange piece 16 is avoided, the efficient work of the heat exchange piece 16 is ensured, the cold is prevented from being transferred to one side of the insulating piece 12, and the influence of the cold on the hot compress effect of the insulating piece 12 is avoided.

Referring to fig. 6, in some embodiments, the heat dissipation element 18 has a first contact surface 181, and the heat exchange element 16 has a second contact surface 161 that is in contact with the first contact surface 181, that is, the heat dissipation element 18 is in surface-to-surface contact with the heat exchange element 16, so that the contact area between the heat dissipation element 18 and the heat exchange element 16 can be increased, and the heat dissipation efficiency of the heat dissipation element 18 to the heat exchange element 16 can be improved. Illustratively, the heat sink 18 may be an active heat sink 18 such as a fan, or a passive heat sink 18 such as a metal such as an aluminum block. The specific type of the heat sink 18 in this embodiment is not limited.

With continued reference to fig. 6, in some embodiments, one of the heat dissipation element 18 and the heat exchange element 16 has a first positioning portion 162, the other of the heat dissipation element 18 and the heat exchange element 16 has a first positioning groove 18a in plug-in fit with the first positioning portion 162, and positioning and installation between the heat dissipation element 18 and the heat exchange element 16 can be achieved through plug-in fit between the first positioning portion 162 and the first positioning groove 18a, so that heat dissipation effect is prevented from being reduced due to loosening between the heat dissipation element 18 and the heat exchange element 16.

Referring to fig. 6-7, in still other embodiments, one of the heat dissipating member 18 and the housing 11 has a second positioning portion 182, the other of the heat dissipating member 18 and the housing 11 has a second positioning groove 11b in plug-fit with the second positioning portion 182, and the positioning and mounting between the heat dissipating member 18 and the housing 11 can be achieved by the plug-fit of the second positioning portion 182 and the second positioning groove 11b, so as to avoid loosening of the housing 11 and the insulating member 12 on the housing 11 relative to the handle 20.

In some embodiments, the beauty instrument 1 also has a photocosmetic function, and phototherapy can regenerate cytokines by activating cells, so that the effect of repairing skin aging is achieved, wrinkles can be effectively removed, the skin is fine, smooth and glossy, and the skin is more youthful. Specifically, referring to fig. 2-3, in order to implement the photocosmetic function, the insulating member 12 is a light-transmitting insulating member 12, the cosmetic head 10 further includes a light emitting component 19, the light emitting component 19 is located in the mounting cavity 11a, and the light emitted by the light emitting component 19 is suitable for being emitted from the light-transmitting insulating member 12 to the outside of the mounting cavity 11a, so as to photocosmetically treat the skin of the user.

In the above embodiment, the electrode assembly 12 does not need to directly contact with the skin of the user through the light-transmitting insulating member 12 to realize the radio frequency beauty function, the heat exchange assembly 15 does not need to additionally provide a skin-contacting part on the basis of the light-transmitting insulating member 12, but uses the better heat conducting property of the light-transmitting insulating member 12 to transfer heat or cold to the skin of the human body, so as to realize the hot compress or cold compress function, and the light emitting assembly 19 does not need to additionally provide a part with the light-transmitting part on the basis of the light-transmitting insulating member 12, but uses the light transmittance of the light-transmitting insulating member 12 to emit light from the light-transmitting insulating member 12 out of the mounting cavity 11a, so as to realize the light beauty function. That is, through the same light-transmitting insulating piece 12, the electrode assembly 13 can be enabled to realize the radio frequency beautifying function, the heat exchange assembly 15 can be enabled to realize the cold compress or hot compress function, the light-emitting assembly 19 can be enabled to realize the light beautifying function, on the basis of guaranteeing the beautifying function of each assembly, each function can be connected together through the light-transmitting insulating piece 12, each function can be mutually cooperated, the better beautifying effect is achieved, the structure of each function is simpler, the structure of the beautifying instrument is simplified, and the design and production difficulty of the beautifying instrument are reduced.

The position of the light emitting component 19 in the mounting cavity 11a may be varied, so long as it is ensured that the light emitted from the light emitting component 19 can be emitted out of the mounting cavity 11a from the light transmitting insulating member 12.
