Description

[Technical field]

[0001] The present invention relates to a handpiece for a skin cosmetic device, and more particularly to a handpiece for a skin cosmetic device that allows visual confirmation of pressure transmitted to the skin. [Background technology]

[0002] Recently, home skin cosmetic devices with various functions such as HIFU (High Intensity Focused Ultrasound), RF (Radio Frequency), galvanic, and ultrasonic have been developed for skin cosmetic treatment and obesity treatment. Since most users of home skin cosmetic devices are non-professionals, the energy output value of the home skin cosmetic device is set significantly lower than that of hospital skin cosmetic devices. Therefore, a home skin cosmetic device cannot be expected to have a practical therapeutic effect unless it comes into contact with the user's skin with the correct pressure and tilt.

[0003] In addition, in non-invasive treatments that require rubbing, hospital-use skin cosmetic devices must maintain a certain pressure to enhance the treatment effect, but this is dependent on the practitioner's senses or experience. Therefore, there is a problem that friction with irregular strength, temperature or pressure can damage the skin, providing a route for viral infection. Summary of the Invention [Problem to be solved by the invention]

[0004] An object of the present invention is to provide a handpiece for a skin cosmetic device that allows the pressure to be visually confirmed and allows treatment to be performed at an optimal pressure at all times, regardless of the practitioner's sense or experience. [Means for solving the problem]

[0005] The handpiece for a skin cosmetic device according to the present invention includes a handpiece body operable by hand; a skin treatment unit connected to an end of the handpiece body and treating the skin; a pressure sensing unit installed in the skin treatment unit and sensing the pressure between the skin and the skin treatment unit; and a pressure display unit that emits light in a plurality of colors according to the pressure value measured by the pressure sensing unit.

[0006] The multiple pressure sensors may be disposed at equal intervals along the edge of the distal end surface of the skin treatment portion.

[0007] The pressure sensing unit may include a plurality of pressure sensors installed at a plurality of points on the skin treatment unit to measure a plurality of pressure values.

[0008] The pressure display unit may emit light in a plurality of colors according to the plurality of pressure values ​​measured by the plurality of pressure sensors and the deviations between the plurality of pressure values.

[0009] The pressure sensor may further include a control unit that transmits a control signal corresponding to the plurality of pressure values ​​measured by the plurality of pressure sensors and a deviation between the plurality of pressure values ​​to the pressure display unit to control the pressure display unit.

[0010] The pressure sensing unit may include a plurality of elastic assemblies that are installed between the handpiece body and the skin treatment unit and whose length is deformed according to the pressure applied by the skin treatment unit to the skin.

[0011] The elastic assembly may include a multi-stage pogo pin, each stage of which is equipped with an elastic body having a different elastic modulus.

[0012] The multi-stage pogo pins include upper stage pogo pins adjacent to the skin treatment unit, lower stage pogo pins adjacent to the handpiece body, and middle stage pogo pins located between the upper stage pogo pins and the lower stage pogo pins, and the elastic modulus of the elastic body mounted on the upper stage pogo pins, the middle stage pogo pins, and the lower stage pogo pins may be greater from the upper stage pogo pins to the lower stage pogo pins.

[0013] The elastic modulus of the upper elastic body mounted on the upper pogo pin may be less than a predetermined pressure reference range, the elastic modulus of the middle elastic body mounted on the middle pogo pin may be within the pressure reference range, and the elastic modulus of the lower elastic body mounted on the lower pogo pin may exceed the pressure reference range.

[0014] The pressure indicator may emit light in a plurality of colors as the length of the elastic assembly changes.

[0015] The pressure measuring device may further include a controller that transmits a control signal to the pressure indicator in response to a change in length of the elastic assembly, and controls the pressure indicator. Effect of the Invention

[0016] The handpiece for a skin cosmetic device according to one embodiment of the present invention allows the pressure applied to the skin to be visually confirmed using a pressure display unit, so that the practitioner can always perform treatment with an optimal pressure regardless of the practitioner's sense or experience.

[0017] In addition, the practitioner or user can check the pressure and deviation displayed on the pressure display unit and adjust the pressure and deviation applied to the skin in real time, thereby maximizing the treatment effect.

[0018] In addition, since the practitioner or user can immediately confirm the stability of the product on the skin, product reliability can be improved. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings, in which: FIG. 1 is a block diagram of a semiconductor device according to an embodiment of the present invention;

[0021] FIG. 1 is a schematic plan view of a handpiece for a skin cosmetic device according to an embodiment of the present invention.

[0022] As shown in FIG. 1, a handpiece for a skin cosmetic device according to an embodiment of the present invention includes a handpiece body 100, a skin treatment unit 200, a pressure sensing unit 300, a pressure display unit 400, and a control unit 500.

[0023] The handpiece body 100 typically has a modified cylindrical shape that can be easily gripped by hand, but is not necessarily so limited and can have a variety of shapes.

[0024] The skin treatment unit 200 is connected to an end of the handpiece body 100 and can treat the skin. The skin treatment unit 200 can include a needle part having a sharp needle shape, but is not necessarily limited thereto, and can have various structures as long as it has a structure capable of treating the skin. That is, the skin treatment unit 200 can have a structure capable of performing HIFU, galvanic, non-invasive or invasive RF treatment, etc.

[0025] The pressure sensing unit 300 is installed in the skin treatment unit 200 and can sense the pressure between the skin (S) and the skin treatment unit 200.

[0026] The pressure sensing unit 300 may include a plurality of pressure sensors 310 installed at a plurality of points on the skin treatment unit 200 to measure a plurality of pressure values.

[0027] FIG. 2 is a diagram illustrating an arrangement of a plurality of pressure sensors according to one embodiment, and FIG. 3 is a diagram illustrating an arrangement of a plurality of pressure sensors according to another embodiment.

[0028] 2 and 3, the pressure sensors 310 may be at least two or more and may be disposed on the distal end surface of the skin treatment portion 200. Such pressure sensors 310 may be disposed at equal intervals along the periphery of the distal end surface of the skin treatment portion 200.

[0029] 2, two pressure sensors 310 may be disposed at equal intervals along the periphery of the distal end surface of the skin treatment portion 200. Here, the two pressure sensors 310 may be disposed at a maximum distance apart in the width direction (W) of the distal end surface of the skin treatment portion 200.

[0030] 3, four pressure sensors 310 may be disposed at equal intervals along the periphery of the distal end surface of the skin treatment unit 200. Here, the four pressure sensors 310 may be disposed at maximum distances along the periphery of the distal end surface of the skin treatment unit 200.

[0031] In this way, the pressure sensors 310 are arranged at equal intervals along the periphery of the distal end surface of the skin treatment unit 200, thereby preventing the handpiece for the skin cosmetic device according to an embodiment of the present invention from being tilted to one side or from measuring pressure when a part of the distal end surface of the skin treatment unit 200 is separated from the skin (S). Therefore, the pressure between the skin (S) and the skin treatment unit 200 can be sensed more accurately.

[0032] In the embodiments shown in Figures 2 and 3, the arrangement structures of two and four pressure sensors are described, respectively, but this is not necessarily limited to this, and the arrangement structure of multiple pressure sensors 310 can be modified and applied in various ways to achieve more accurate pressure measurement.

[0033] The pressure display unit 400 may emit light in a plurality of colors according to the pressure value measured by the pressure sensing unit 300. Specifically, the pressure display unit 400 may emit light in a plurality of colors according to the plurality of pressure values ​​measured by the plurality of pressure sensors 310 and the deviation between the plurality of pressure values. Such a pressure display unit 400 may be configured with an LED.

[0034] The control unit 500 can transmit a control signal corresponding to a plurality of pressure values ​​measured by the plurality of pressure sensors 310 and a deviation between the plurality of pressure values ​​to the pressure display unit 400 and control the pressure display unit 400.

[0035] FIG. 4 is a diagram showing a color change of a pressure display unit according to a pressure applied to a user's skin by a handpiece for a skin cosmetic device according to an embodiment of the present invention.

[0036] 4, as the handpiece for a skin cosmetic device according to an embodiment of the present invention increases the pressure applied to the user's skin (S), the color of the pressure display unit 400 can change from yellow (Y), to green (G), and then to red (R). When the color of the pressure display unit 400 is yellow (Y), it indicates that the pressure and deviation standard ranges have not been reached, when the color of the pressure display unit 400 is green (G), it indicates that the pressure and deviation standard ranges are satisfied, and when the color of the pressure display unit 400 is red (R), it indicates that the pressure and deviation standard ranges have been exceeded.

[0037] In this embodiment, the color of the pressure display unit 400 changes from yellow (Y), to green (G), and to red (R), but this is not limited to this and the pressure change can be displayed by changing to various colors.

[0038] As described above, the handpiece for a skin cosmetic device according to one embodiment of the present invention can visually confirm the pressure and deviation applied to the skin using the pressure display unit, so that treatment can always be performed with the optimal pressure regardless of the sensation or experience of the practitioner or user.

[0039] That is, the practitioner or user can check the pressure and deviation displayed on the pressure display unit and adjust the pressure and deviation applied to the skin in real time, thereby maximizing the treatment effect.

[0040] In addition, since the practitioner or user can immediately confirm the stability of the product on the skin, product reliability can be improved.

[0041] Meanwhile, while in the above embodiment the pressure sensing portion includes a plurality of pressure sensors, other embodiments are possible in which the pressure sensing portion includes an elastic assembly.

[0042] Hereinafter, a handpiece for a skin cosmetic device according to another embodiment of the present invention will be described in detail with reference to FIGS.

[0043] FIG. 5 is a schematic plan view of a handpiece for a skin cosmetic device according to another embodiment of the present invention.

[0044] The other embodiment shown in FIG. 5 is substantially the same as the embodiment shown in FIG. 1 except for the structure of the pressure sensing portion, and therefore a repeated description will be omitted.

[0045] As shown in FIG. 5, a handpiece for a skin cosmetic device according to another embodiment of the present invention includes a handpiece body 100, a skin treatment unit 200, a pressure sensing unit 300, a pressure display unit 400, and a control unit 500.

[0046] The pressure sensing unit 300 may be installed between the handpiece body 100 and the skin treatment unit 200. The pressure sensing unit 300 may include a plurality of elastic assemblies 320 whose length changes according to the pressure applied by the skin treatment unit 200 to the skin (S). One elastic assembly 320 may include a multi-stage pogo pin, with elastic bodies 32 having different elastic coefficients mounted on each stage. Hereinafter, the elastic assembly 320 will be described taking a multi-stage pogo pin as an example.

[0048] As shown in FIG. 6, the multi-stage pogo pin 320 may include an upper stage pogo pin 320u adjacent to the skin treatment unit 200, a lower stage pogo pin 320d adjacent to the handpiece body 100, and a middle stage pogo pin 320m located between the upper stage pogo pin 320u and the lower stage pogo pin 320d.

[0049] Here, the elastic modulus of the elastic body 32 mounted on the upper pogo pin 320u, the middle pogo pin 320m, and the lower pogo pin 320d may be greater from the upper pogo pin 320u to the middle pogo pin 320m, and then to the lower pogo pin 320d. The elastic modulus of the elastic body 32u, 32m, and 32d of the upper pogo pin 320u, the middle pogo pin 320m, and the lower pogo pin 320d may correspond to a preset pressure standard.

[0050] In other words, the elastic coefficient of the upper-stage elastic body 32u mounted on the upper-stage pogo pin 320u may be less than a predetermined pressure standard range, the elastic coefficient of the middle-stage elastic body 32m mounted on the middle-stage pogo pin 320m may be within the pressure standard range, and the elastic coefficient of the lower-stage elastic body 32d mounted on the lower-stage pogo pin 320d may exceed the pressure standard range.

[0051] The pressure indicator 400 can emit light in a variety of colors by changing the length (L) of the elastic assembly 320. Such a pressure indicator 400 can be made of an LED.

[0052] The control unit 500 can transmit a control signal according to the length deformation of the elastic assembly to the pressure display unit 400 to control the pressure display unit 400 .

[0053] FIG. 7 is a diagram showing a change in color of a pressure display unit according to a pressure applied to a user's skin by a handpiece for a skin cosmetic device according to another embodiment of the present invention.

[0054] As shown in FIG. 7, by increasing the pressure applied to the user's skin (S) by the handpiece for a skin cosmetic device according to another embodiment of the present invention, the length of the elastic assembly 320 changes to L, L', and L'', and the color of the pressure display unit 400 can change to yellow (Y), green (G), and red (R) correspondingly. When the color of the pressure display unit 400 is yellow (Y), it indicates that the pressure reference range has not been reached, when the color of the pressure display unit 400 is green (G), it indicates that the pressure reference range is satisfied, and when the color of the pressure display unit 400 is red (R), it indicates that the pressure reference range has been exceeded.
