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 handle 20 and a cosmetic head 10 connected to 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 mounted on 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, an inner wall surface of the handle 20 is provided with a first protrusion 21 and a second protrusion 22 disposed opposite to each other, and a protrusion height of the first protrusion 21 is higher than a protrusion height of the second protrusion 22. The housing 11 includes an elastic arm 111, the elastic arm 111 has a first clamping groove 111a, the other side of the housing 11 opposite to the elastic arm 111 has a second clamping groove 112a, the first protrusion 21 is clamped into the first clamping groove 111a, and the second protrusion 22 is clamped into the second clamping groove 112 a. By the snap-fit of the first protrusion 21 and the first clamping groove 111a, the snap-fit of the second protrusion 22 and the second clamping groove 112a, and the mating structure of the first protrusion 21 and the first clamping groove 111a and the mating structure of the second protrusion 22 and the second clamping groove 112a are located on two opposite sides of the housing 11, stability of the housing 11 after being mounted on the handle 20 can be improved. 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 is co-configured with the housing 11 and has 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 provided in a sheet shape, and the thickness of the insulating member 12 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, radio frequency beauty treatment is generally implemented by using a resistor model, that is, two radio frequency electrodes of a radio frequency beauty treatment instrument are simultaneously in contact with skin of a user, and when high frequency alternating current is supplied to the two radio frequency electrodes, current flows from one radio frequency electrode to the other radio frequency electrode through the skin. Through modeling, the skin can be equivalent to a resistor or a combination of the resistor and a capacitor, has specific impedance, and continuously passes through the skin and radio frequency waves directly penetrate through the skin surface layer so as to achieve the purpose of heating collagen tissues and cell tissues, thereby achieving the beauty effect.

Unlike the resistor model, the cosmetic instrument 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 and are disposed opposite to the inner side surface of the insulating member 12, and the insulating member 12 spaces the first electrode 131 and the second electrode 132 from the skin. When the high-frequency alternating current is supplied to the first electrode 131 and the second electrode 132, the portion of the skin facing the first electrode 131 induces a third electrode having a polarity opposite to that of the first electrode 131, and the first electrode 131 and the third electrode are separated by the insulating member 12, so that the whole can be equivalent to a capacitor. Similarly, the portion of the skin opposite to the second electrode 132 induces a fourth electrode of opposite polarity to the second electrode 132, and the second electrode 132 and the fourth electrode are separated by the insulating member 12, which may be equivalently another capacitor as a whole. When alternating current is supplied to the first electrode 131 and the second electrode 132, one of the first electrode 131 and the second electrode 132 is a positive electrode, and the other is a negative electrode, and thus the limits of the third electrode and the fourth electrode are also opposite, and a 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, so that 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 granular layer, a transparent layer and a horny layer from inside to outside, and the skin barrier is generally referred to as the horny layer of the epidermis, which is a barrier for reducing the passive diffusion of moisture from the skin and also serves as a barrier for preventing other molecules (including irritants) from entering the skin. The skin barrier is primarily formed as a "brick wall" structure by the attachment of keratinocytes and intercellular lipids, the tight attachment of which is 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. a weak or defective "brick wall" structure. On the one hand, impaired skin barrier function, accelerated transdermal moisture loss and loss of skin nutrients, which lead to a significant decrease in ceramide content, while upregulation of sphingolipid levels is associated with reduced skin barrier stability; on the other hand, the fragile skin barrier can enhance the penetration effect of the irritant or allergen, the nerve endings are not fully protected, and deeper skin is exposed to microorganisms and external stimulus, so that the local inflammatory state of the skin is induced, and symptoms such as redness, itching, burning and stinging occur. And studies have shown that: the impaired integrity of the skin barrier increases the incidence of atopic dermatitis, and the risk of allergy in individuals with sensitive skin is also 5 times higher.

The induced current of this embodiment can produce heat when flowing in skin to can accelerate ageing apoptosis, the cell proliferation differentiation of induced granulosa layer, form the stratum corneum that has "brick wall" structure after the apoptosis, stratum corneum is thickened and become dense, can play the effect of repairing skin barrier, improves sensitive muscle, promotes dermis layer collagen regeneration simultaneously, effectively locks moisture, makes skin become compact, and improves the wrinkle.

In some embodiments, in order to enable the capacitor model to be configured between the electrode assembly 13 and the skin of the human body, a distance from a surface of the first electrode 131 and the second electrode 132 facing the insulating member 12 to a surface of the insulating member 12 for contacting the skin of the human body is greater than or equal to 0.4mm, and a distance between the first electrode 131 and the second electrode 132 and the skin is also greater than or equal to 0.4mm when the insulating member 12 is in skin-contacting operation, a third electrode is induced by a portion of the skin facing the first electrode 131, and the first electrode 131 and the third electrode are configured to form a capacitor. Similarly, the portion of the skin opposite to the second electrode 132 induces a fourth electrode, and the second electrode 132 and the fourth electrode are configured to form another capacitor. The capacitor formed by the first electrode 131 and the second electrode 132 can induce induced current on the skin of the human body, and meanwhile, the first electrode 131 and the second electrode 132 convert electric energy into electromagnetic waves to radiate to the skin of the human body, so that the effect of radio frequency beauty is achieved. When the thickness D of the insulating member 12 is less than 0.4mm, the capacitor model fails due to the too close distance between the first and second electrodes 131 and 132 and the skin, and the cosmetic effect cannot be achieved.

The electrode assembly 13 is disposed opposite to the inner side surface of the insulating member 12 in the mounting cavity 11a, and in a specific implementation, the electrode assembly 13 may be disposed at intervals from the inner side surface of the insulating member 12, and it is only necessary to ensure that a distance from a surface of the first electrode 131 and the second electrode 132 facing the insulating member 12 to a surface of the insulating member 12 for contacting with skin of a human body is greater than or equal to 0.4 mm.

In other embodiments, the electrode assembly 13 may be directly attached to the inner side of the insulating member 12, where the first electrode 131 and the second electrode 132 are in contact with the insulating member 12, 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 the thickness D of the insulating member, and 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 may be obtained by directly setting the thickness of the insulating member 12, so that the electrode assembly 13 is not required to be fixed to the insulating member 12 by other structures, and the inner side of the remaining insulating member 12 of the electrode assembly 13 is directly separated from the insulating member 12. In addition, when the electromagnetic wave propagates in the air, compared with the scheme that when the electrode assembly 13 is spaced from the inner side surface of the insulating member 12, the electromagnetic wave of the first electrode 131 and the second electrode 132 needs to be conducted to the insulating member 12 through the air and then conducted to the skin of the human body through the insulating member 12, the electrode assembly 13 of the embodiment is attached to the inner side surface of the insulating member 12, the electromagnetic radiation generated by the first electrode 131 and the second electrode 132 is directly conducted to the skin of the human body through the insulating member 12, and the air propagation attenuation does not exist, so that the electromagnetic wave conduction efficiency is higher and the utilization rate is higher.

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. It should be understood that the first electrode 131 and the second electrode 132 may not be bonded to the insulating member 12, and the first electrode 131 and the second electrode 132 may be disposed opposite to the inner surface of the insulating member 12, so that the capacitor model may be configured when the distance between the first electrode 131 and the second electrode 132 and the skin of the human body is sufficiently large.

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.

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.

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 electrically connected to the first electrode 131 and the second electrode 132, and through which high-frequency ac power can be supplied to the first electrode 131 and the second electrode 132, and rf signals can be excited, 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, so that the working voltage of the electrode assembly 13 is higher, the short-wave frequency of the radiation energy of the electrode assembly 13 is higher, and a larger induction current can be induced at a deeper skin position to provide larger repair energy, thereby 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, in some embodiments, the first electrode 131 and the second electrode 132 have a first distance D1 therebetween, where the first distance D1 is greater than or equal to 1.5mm, and the applicant has found that by setting the first distance D1 to be greater than or equal to 1.5mm, the probability of breakdown of the rf signal of the shortwave rf generator between the first electrode 131 and the second electrode 132 is reduced, so that the beauty instrument 1 operates more stably and more safely. 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.

In some embodiments, the first distance D1 is less than or equal to 5mm, so that the overall size of the electrode assembly 13 can be reduced, which is advantageous in reducing the overall size of the cosmetic head 10, when the user's skin is not planar in actual beauty, but there are some corner regions, including skin depressions such as eyelets and skin protrusions such as noses, smaller cosmetic heads 10 can more closely fit the depressions of the skin, thereby achieving better cosmetic effect, and smaller cosmetic heads 10 can allow a substantial portion of the insulator 12 to be affixed to the skin, thereby allowing more rf energy to be applied to the skin, 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.

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, at least one of the first electrode 131 and the second electrode 132 has an area of 6cm or less ² In this way, the overall size of the electrode assembly 13 can be reduced, thereby being beneficial to reducing the overall size of the beauty head 10, and in actual beauty, the smaller beauty head 10 can be more tightly attached to the concave portion of the skin, thereby realizing better beauty effect, and the smaller beauty head 10 can attach the vast majority of the insulating member 12 to the skin, thereby enabling the radio frequency energy to act on the skin more, and further improving the energy utilization rate. The areas of the first electrode 131 and the second electrode 132 are larger than 6cm ² When the beauty head 10 is bigger, the partial area of the beauty head 10The domain cannot be in contact with the skin, resulting in a reduction in energy utilization rate, and when it is desired to make up for the skin depression, it is also impossible to conveniently attach the cosmetic head 10 to or near the skin depression, resulting in deterioration of the cosmetic effect for the skin depression.

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.

Referring to fig. 2-3, in some embodiments, the beauty treatment head 10 further includes a buffer member 15, the buffer member 15 is disposed in the mounting cavity 11a and has a deformability, the electrode assembly 13 is disposed between the buffer member 15 and the insulating member 12, and the buffer member 15 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, thereby enabling more rf energy to enter the skin and further improving the beauty treatment effect. And when the insulator 12 is slightly deformed by skin extrusion, the buffer member 15 can buffer the extrusion force of the insulator 12 to the electrode assembly 13 and compress the electrode assembly 13 against the inner side surface of the insulator 12 by its elastic restoring force.

Referring to fig. 5, further, the buffer member 15 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 buffer member 15 has elastic restoring force, so that the first electrode 131 and the second electrode 132 can be 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 the first electrode assembly is opposite to the skin through the insulating member 12, thereby enabling more radio frequency 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.

In some embodiments, the beauty instrument 1 further has a skin temperature control function of the insulation member 12, and the beauty instrument 1 can perform cold or hot compress on the skin of the user and can maintain a desired specific temperature when the cold or hot compress is performed. 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, the cosmetic head 10 includes a heat exchange member 16 disposed within the 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 member 16 further includes a heat conducting member 17, and the heat conducting member 17 may be the buffer member 15 described above, or may be a member different from the buffer member 15. The heat conducting piece 17 is arranged in the mounting cavity 11a and is abutted with the inner side surface of the insulating piece 12, the heat exchanging piece 16 is abutted with the surface, deviating from the electrode assembly 13, of the heat conducting piece 17, and the heat conducting piece 17 can transfer heat or cold of the heat exchanging piece 16 to the insulating piece 12 through the heat conducting piece 17, so that temperature adjustment of the insulating piece 12 is achieved.

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 the middle, and 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 sequentially arranged on the central axis of the insulating member 12, but not on different axes, so that dislocation arrangement is formed, and 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 can be reduced on the basis that the cosmetic head 10 is ensured to have a radio frequency cosmetic function and an attaching temperature control function, thereby being more beneficial to the cosmetic skin depression.

Further, in order to reduce the number of parts, the size of the beauty head 10 may be further reduced, and the buffer member 15 may be used as the heat conductive member 17, and in this case, 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 heat or cold generated by the heat exchanging piece 16 is transmitted 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 conducting member 17 can also realize the function of the buffer member 15, that is, the electrode assembly 13 is pressed against the inner side surface of the insulating member 12, so as to reduce the distance between the electrode assembly 13 and the skin, and further improve the utilization rate of radio frequency energy. The elastic heat conducting member 17 is compressed by the insulating member 12, so that the elastic heat conducting member 17 can be better clung to the inner side surface of the insulating member 12, the heat conducting efficiency is improved, and the influence of the thickness of the first electrode 131 and the second electrode 132 on the heat conducting efficiency of the elastic heat conducting member 17 is reduced. The elastic heat conductive member 17 may be, for example, a heat conductive silicone.

Further, compared with the arrangement that the electrode assembly 13 is spaced from the inner side surface of the insulating member 12, when the electrode assembly 13 is attached to the inner side surface of the insulating member 12, the electrode assembly 13 has a better heat conducting property as a conductor, so that the heat or cold of the heat conducting member 17 can be directly conducted to the insulating member 12 and then conducted to the skin of the human body through the insulating member 12, thereby improving the efficiency of conducting the heat or cold of the heat conducting member 17 to the skin of the human body and improving the energy utilization rate. In addition, when the beauty instrument 1 cold-compress the skin of the human body, the heat exchanging member 16 cools to lower the temperature of the insulating member 12. However, if the indoor air temperature is high, if the electrode assembly 13 is spaced from the inner side surface of the insulator 12, condensed water may be generated on the inner side surface of the insulator 12 after the high-temperature indoor air enters the mounting cavity 11a, and the condensed water may cause a short circuit of the electronic circuits (such as the first electrode 131 and the second electrode 132) inside the cosmetic 1, and by attaching the electrode assembly 13 to the inner side surface of the insulator 12, the contact between the high-temperature air and the inner side surface of the insulator 12 and the probability of generating condensed water may be reduced.

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 corresponding heat during the working process, please refer to fig. 2-3, the cosmetic head 10 further includes a heat dissipation member 18, the heat dissipation member 18 is abutted against one side of the heat exchange member 16 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 is abutted against or abutted 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 member 16 performs refrigeration work, the heat exchange member 17 can better transfer cold to the insulating member 12, so as to realize the cold compress function of the insulating member 12, and meanwhile, the heat exchange member 16 can quickly transfer the heat generated by the heat exchange member 16 to the handle 20 or the internal air of the handle 20 through the heat dissipation member 18, and transfer the heat to the external air through the handle 20, so as to avoid the heat from influencing the refrigeration work of the heat exchange member 16, ensure that the heat exchange member 16 can work efficiently, and avoid the heat from being transferred to the side of the insulating member 12, so as to avoid the influence on the cold compress effect of the insulating member 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.
