Tips for High-Frequency Skin Beauty Devices

[0001] The present invention relates to a tip for a high-frequency skin beauty device.

[0002] High-frequency skin care devices are widely used for cosmetic purposes. These devices emit high-frequency waves to the skin, promoting collagen regeneration. Meanwhile, the tips provided with the high-frequency skin care devices are responsible for applying the high-frequency waves to the skin.

[0003] A conventional tip for a high-frequency skin beauty device includes a second substrate that receives power from a power module, a first substrate that is movable toward the second substrate, and a signal transmission pin that electrically connects the second substrate and the first substrate. One end of the signal transmission pin is coupled to the second substrate, and the other end of the signal transmission pin is forcefully coupled to the first substrate. Therefore, when the first substrate is moved, there is a problem in that frictional damage occurs between the first substrate and the signal transmission pin, and the contact resistance between the first substrate and the signal transmission pin increases.

[0007] In addition, the connector may include a first member coupled to the first substrate; a second member coupled to the second substrate; and a third member that connects the first member and the second member and is elastic.

[0008] Additionally, the third member may have at least one bend.

[0009] Additionally, the bend may include a zigzag shape.

[0010] Additionally, the connector may include a wire electrically connecting the first substrate and the second substrate and having at least one bend formed therein.

[0012] Additionally, the electrode may have a needle shape or a pin shape.

[0013] Additionally, the device may further include a driving module that moves the first substrate in the first direction or the second direction.

[0014] In addition, the housing may include an outer frame; a base connected to the outer frame and having at least one through hole formed therein through which at least one electrode passes; and a guide frame disposed inside the outer frame to guide movement of the first substrate.

[0027] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0028] FIG. 1 is a perspective view showing a tip for a high-frequency skin beauty device according to one embodiment of the present invention, FIG. 2 is an exploded perspective view showing a tip for a high-frequency skin beauty device according to one embodiment of the present invention, FIG. 3 is a perspective view showing a connector of a tip for a high-frequency skin beauty device according to one embodiment of the present invention, and FIG. 4 is a cross-sectional view showing a tip for a high-frequency skin beauty device according to one embodiment of the present invention.

[0029] As illustrated in FIGS. 1 to 4, a tip for a high-frequency skin beauty device according to one embodiment of the present invention may include a housing (100), a first substrate (200), at least one electrode (300), a second substrate (400), and a connector (500).

[0030] The housing (100) is the basic body of the present invention and may include an outer frame (110), a base (120), and a guide frame (130).

[0031] The outer frame (110) may be opened at the top and bottom. Here, at least one electrode (300) and a first substrate (200) may be accommodated at the bottom of the outer frame (110), a guide frame (130) and a second substrate (400) may be accommodated at the top of the outer frame (110), and a connector (500) may be accommodated between the top and bottom of the outer frame (110).

[0032] The base (120) may be connected to the external frame (110) so that at least one through-hole (121) through which at least one electrode (300) passes may be formed. Here, the electrode (300) may protrude outwardly from the housing (100) through the through-hole (121). For example, the through-holes (121) may be arranged in a matrix shape in the base (120).

[0033] The guide frame (130) may be placed inside the outer frame (110) and serve to guide the movement of the first substrate (200). This guide frame (130) may guide the movement of the plunger (700) coupled with the first substrate (200), thereby guiding the movement of the first substrate (200).

[0034] A guide channel (131) may be formed inside the guide frame (130). The guide channel (131) may be arranged so that the plunger (700) can reciprocate, and the plunger (700) may move along the guide channel (131). For example, the guide channel (131) may be formed along the central axis of the guide frame (130).

[0035] An elastic member (600) that generates an elastic force to move the plunger (700) in a second direction may be disposed in the guide channel (131). This elastic member (600) may move and return the plunger (700) in the second direction after the plunger (700) has been moved in the first direction. For example, the elastic member may be interposed between a first groove (701) sunken into the plunger (700) and a second groove (132) formed in the guide channel (131).

[0036] The guide frame (130) may be detachably connected to the handpiece. For example, a hook may be formed on the guide frame (130), and a hook groove may be formed on the handpiece to allow the hook to be hooked and fixed. Here, the hook may be formed to protrude from the upper side of the guide frame (130). As another example, a hook groove may be formed on the guide frame (130), and a hook may be formed to be hooked and fixed to the hook groove. Here, the hook groove may be formed to be recessed into the upper side of the guide frame (130).

[0037] The handpiece can be used as a handle for the operator to grasp. Additionally, the handpiece can house a power module that supplies power to the second substrate (400).

[0038] The first substrate (200) can serve to transmit power supplied from the second substrate (400) to the electrode (300). The first substrate (200) can be placed inside the housing (100). Meanwhile, the first substrate (200) can be installed to be movable in a first direction away from the second substrate (400) or a second direction toward the second substrate (400). At this time, the first substrate (200) can be moved in the first direction or the second direction by the driving module.

[0039] The drive module may function to move the first substrate (200) in a first direction or a second direction. For reference, the first direction may be the direction in which the lower side or the electrode (300) protrudes outward from the housing (100), and the second direction may be the direction in which the upper side or the electrode (300) is inserted into the interior of the housing (100).

[0040] The drive module (not shown) may include an actuator (not shown) and a plunger (700).

[0041] The actuator is positioned outside the housing (100) and can move the plunger (700) in a first direction or a second direction. For example, the actuator may include a screw shaft rotated by a driving motor and a moving nut that moves along the screw shaft by the rotation of the screw shaft. As another example, the actuator may include a rod provided in a cylinder that can be moved by hydraulic pressure.

[0042] The plunger (700) is arranged inside the housing (100) and connected to the first substrate (200), and can be moved in the first direction or the second direction by the actuator. The plunger (700) can be arranged to be movable along the guide channel (131).

[0043] At least one electrode (300) may be arranged on the first substrate (200) and may serve to apply high frequency waves to the skin. For example, referring to FIGS. 1 to 4, the electrodes (300) may be configured in multiple numbers, and the multiple electrodes (300) may be arranged at intervals on the lower surface of the first substrate (200) and may serve to apply high frequency waves to the skin. As another example, the electrodes (300) may include a needle shape or a pin shape.

[0044] The second substrate (400) may be positioned inside the housing (100) facing the first substrate (200) and may serve to supply power to the first substrate (200). The second substrate (400) may receive power from a power module positioned inside the handpiece. In addition, the second substrate (400) may be positioned inside the guide frame (130).

[0045] The connector (500) is arranged inside the housing (100) and can electrically connect the first substrate (200) and the second substrate (400). Here, the connector (500) can have a length greater than the distance between the first substrate (200) and the second substrate (400). Therefore, the present invention can prevent frictional damage to the connector (500) since only the length of the connector (500) changes when the first substrate (200) or the second substrate (400) moves. In addition, the connector (500) and the first substrate (200) are directly coupled, and the connector (500) and the second substrate (400) are also directly coupled. In this way, the present invention can prevent contact resistance between the first substrate (200) and the second substrate (400) by directly connecting the first substrate (200) and the second substrate (400) through the connector (500). For reference, the direct connection may include welding connection and soldering connection.

[0046] The connector (500) includes a first member (510), a second member (520), and a third member (530).

[0047] The first member (510) can be coupled to the first substrate (200). The first member (510) can be directly coupled to the first substrate (200).

[0048] The second member (520) can be coupled to the second substrate (400). This second member (520) can be directly coupled to the second substrate (400).

[0049] The third member (530) connects the first member (510) and the second member (520) and may be elastic. In other words, the third member (530) may have a shape that allows for length adjustment by elasticity.

[0050] For example, the third member (530) may have a zigzag shape. Specifically, the zigzag shape may have a shape in which a first bend pattern bent in a third direction orthogonal to the first direction and a second bend pattern bent in a fourth direction opposite to the third direction are alternately connected. For reference, the third direction may be to the left, and the fourth direction may be to the right.

[0051] For example, the third member (530) can generate an elastic force that moves the first substrate (200) in the second direction. Accordingly, the plunger (700) can be quickly moved and returned in the second direction by the elastic force of the third member (530) and the elastic force of the elastic member (600).

[0052] Hereinafter, a process for applying high-frequency waves to the skin using a tip for a high-frequency skin beauty device according to one embodiment of the present invention will be described. The following process can be performed by a robotic arm or a practitioner.

[0053] FIG. 5 is a cross-sectional view showing a state in which a first substrate of a tip for a high-frequency skin beauty device according to one embodiment of the present invention is moved in a first direction.

[0054] First, the first substrate (200) is moved in a first direction, and at least one electrode (300) protrudes outward from the housing (100) through the through hole (121). Here, if at least one electrode (300) is in the form of a needle, it can be inserted into the skin. In addition, if at least one electrode (300) is in the form of a pin, it can be in close contact with the skin. Furthermore, the third member (530) of the connector (500) can be extended in the first direction. (See FIG. 5)

[0055] Thereafter, power supplied from the power module is transmitted to at least one electrode (300) via the second substrate (400), connector (500), and first substrate (200). As a result, high frequency is applied to the skin from at least one electrode (300).

[0056] Hereinafter, various embodiments of a connector (500) of a tip for a high-frequency skin beauty device according to one embodiment of the present invention will be described.

[0057] FIGS. 6 to 9 are cross-sectional views showing various embodiments of a connector of a tip for a high-frequency skin beauty device according to one embodiment of the present invention.

[0058] As illustrated in FIG. 6, the connector (500) may include a flexible printed circuit board (540), a first clamp (550), and a second clamp (560).

[0059] A flexible printed circuit board (540) can electrically connect a first substrate (200) and a second substrate (400). The flexible printed circuit board (540) can have a length longer than the maximum distance between the first substrate (200) and the second substrate (400). Accordingly, the flexible printed circuit board (540) can be extended when the first substrate (200) moves in the first direction, and can be bent when the first substrate (200) moves in the second direction.

[0060] The first clamp (550) is electrically connected to the first substrate (200) and can be detachably fixed to one side of the flexible printed circuit board (540).

[0061] The second clamp (560) is electrically connected to the second substrate (400) and the other side of the flexible printed circuit board (540) can be detachably fixed.

[0062] As illustrated in FIG. 7, the connector (500) may include a rigid-flex printed circuit board (570). This rigid-flex printed circuit board may electrically connect the first substrate (200) and the second substrate (400). In addition, the rigid-flex printed circuit board (570) may have a length longer than the maximum distance between the first substrate (200) and the second substrate (400). Accordingly, the rigid-flex printed circuit board may be extended when the first substrate (200) moves in the first direction, and may be bent when the first substrate (200) moves in the second direction.

[0063] As illustrated in FIG. 8, the connector (500) may include a wire (580). The wire (580) electrically connects the first substrate (200) and the second substrate (400) and may have at least one bend formed therein. In addition, the wire (580) may have a length longer than the maximum distance between the first substrate (200) and the second substrate (400). Accordingly, the wire (580) may be extended when the first substrate (200) moves in the first direction and may be bent when the first substrate (200) moves in the second direction.

[0064] According to the present invention, a tip for a high-frequency skin beauty device according to one embodiment of the present invention can prevent frictional damage to a connector (500) that electrically connects a first substrate (200) and a second substrate (400), and has the effect of reducing contact resistance between the first substrate (200) and the second substrate (400).

[0065] While the embodiments of the present invention have been described above with reference to the attached drawings, those skilled in the art will appreciate that the present invention can be implemented in other specific forms without altering the technical concept or essential features thereof. Therefore, the embodiments described above should be understood to be illustrative in all respects and not restrictive.
