Description

【Technical Field】 【0001】 The present invention relates to a handpiece for a skin beauty device, and more particularly, to a handpiece for a skin beauty device that can visually confirm the pressure transmitted to the skin. 【Background Art】 【0002】 Recently, for skin beauty and obesity treatment, etc., household skin beauty devices having various functions such as HIFU (High Intensity Focused Ultrasound), RF (Radio Frequency), galvanic, and ultrasonic have been developed. Since most users of household skin beauty devices are non-professionals, the energy output value of household skin beauty devices is set significantly lower than that of hospital skin beauty devices. Therefore, if a household skin beauty device does not contact the user's skin with accurate pressure, inclination, etc., an actual treatment effect cannot be expected. 【0003】 Also, hospital skin beauty devices also need to maintain a predetermined pressure to enhance the treatment effect during non-invasive procedures that require a rubbing operation, but it depends on the sensation or experience of the operator. Therefore, there is a problem that irregular intensity, temperature, or pressure friction may damage the skin, thereby providing a route for virus infection. 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0004】 An object of the present invention is to provide a handpiece for a skin beauty device that can visually confirm pressure and can always perform treatment with an optimal pressure regardless of the sensation or experience of the operator. 【Means for Solving the Problems】 【0005】 The handpiece for a skin aesthetic device according to the present invention includes: a handpiece body that can be operated by hand; a skin treatment section connected to the end of the handpiece body for treating the skin; a pressure sensing section installed in the skin treatment section for sensing the pressure between the skin and the skin treatment section; and a pressure display section that emits light in multiple colors according to the pressure value measured by the pressure sensing section. 【0006】 The plurality of pressure sensors can be arranged at equal intervals along the edges of the tip surface of the skin treatment area. 【0007】 The pressure sensing unit may include multiple pressure sensors installed at multiple locations in the skin treatment area to measure multiple pressure values. 【0008】 The pressure display unit can emit light in multiple colors according to the multiple pressure values ​​measured by the multiple pressure sensors and the deviation between the multiple pressure values. 【0009】 The system may further include a control unit that transmits the plurality of pressure values ​​measured by the plurality of pressure sensors, and control signals corresponding to the deviation between the plurality of pressure values, to the pressure display unit and controls the pressure display unit. 【0010】 The pressure sensing unit may include a plurality of elastic assemblies installed between the handpiece body and the skin treatment unit, whose length deforms in accordance with the pressure applied by the skin treatment unit to the skin. 【0011】 The elastic assembly may include a multi-stage pogo pin, each stage having an elastic body with a different elastic modulus. 【0012】 The multi-stage pogo pin includes an upper pogo pin adjacent to the skin treatment area, a lower pogo pin adjacent to the handpiece body, and a middle pogo pin located between the upper and lower pogo pins. The elastic modulus of the elastic body mounted on the upper, middle, and lower pogo pins may increase from the upper pogo pin to the lower pogo pin. 【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 can emit light in multiple colors as the length of the elastic assembly deforms. 【0015】 The system may further include a control unit that transmits a control signal corresponding to the deformation of the length of the elastic assembly to the pressure display unit and controls the pressure display unit. [Effects of the Invention] 【0016】 A handpiece for a skin aesthetic device according to one embodiment of the present invention allows for visual confirmation of the pressure applied to the skin using the pressure display unit, making it possible to always perform treatment with the optimal pressure, regardless of the practitioner's senses or experience. 【0017】 Furthermore, the practitioner or user can adjust the pressure and deviation applied to the skin in real time by checking the pressure and deviation displayed on the pressure display unit, thereby maximizing the effectiveness of the treatment. 【0018】 Furthermore, since the practitioner or user can immediately confirm the stability of the product on the skin, product reliability can be improved.

The present invention can be embodied in various different forms and is not limited to the embodiments described herein. 【0021】 FIG. 1 is a schematic plan view of a handpiece for a skin beauty device according to an embodiment of the present invention. 【0022】 As shown in FIG. 1, a handpiece for a skin beauty device according to an embodiment of the present invention includes a handpiece main 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 main body 100 usually has a deformed cylindrical shape that can be easily grasped by hand, but is not necessarily limited thereto, and various shapes are possible. 【0024】 The skin treatment unit 200 is connected to the end of the handpiece body 100 and can treat the skin. The skin treatment unit 200 may include a needle-shaped section, but is not necessarily limited to this; various structures are possible as long as they can treat the skin. In other words, the skin treatment unit 200 can be a structure that enables HIFU, galvanic, non-invasive or invasive RF treatments, 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 multiple pressure sensors 310 installed at multiple locations on the skin treatment unit 200 to measure multiple pressure values. 【0027】 Figure 2 illustrates the arrangement structure of multiple pressure sensors according to one embodiment, and Figure 3 illustrates the arrangement structure of multiple pressure sensors according to another embodiment. 【0028】 As shown in Figures 2 and 3, the multiple pressure sensors 310 may be at least two or more in number and can be arranged on the tip surface of the skin treatment section 200. Such multiple pressure sensors 310 can be arranged at equal intervals along the periphery of the tip surface of the skin treatment section 200. 【0029】 As one embodiment, as shown in Figure 2, two pressure sensors 310 may be arranged at equal intervals along the periphery of the tip surface of the skin treatment section 200. Here, the two pressure sensors 310 may be arranged with the maximum possible separation in the width direction (W) of the tip surface of the skin treatment section 200. 【0030】 In another embodiment, as shown in Figure 3, four pressure sensors 310 may be arranged at equal intervals along the periphery of the tip surface of the skin treatment section 200. Here, the four pressure sensors 310 may be arranged as far apart as possible along the periphery of the tip surface of the skin treatment section 200. 【0031】 In this way, by arranging the multiple pressure sensors 310 at equal intervals along the periphery of the tip surface of the skin treatment section 200, it is possible to prevent the handpiece for the skin cosmetic device according to one embodiment of the present invention from tilting to one side, or from measuring pressure when a part of the tip surface of the skin treatment section 200 is separated from the skin (S). Therefore, the pressure between the skin (S) and the skin treatment section 200 can be sensed more accurately. 【0032】 In the embodiments shown in Figures 2 and 3, arrangements of two and four pressure sensors, respectively, have been described. However, the arrangement of the multiple pressure sensors 310 is not necessarily limited to these configurations, and various changes can be made to achieve more accurate pressure measurement. 【0033】 The pressure display unit 400 can emit light in multiple colors according to the pressure value measured by the pressure sensing unit 300. Specifically, the pressure display unit 400 can emit light in multiple colors according to multiple pressure values ​​measured by multiple pressure sensors 310, and the deviation between multiple pressure values. Such a pressure display unit 400 can be made up of LEDs. 【0034】 The control unit 500 can transmit control signals to the pressure display unit 400 that correspond to multiple pressure values ​​measured by the multiple pressure sensors 310, and the deviation between the multiple pressure values, thereby controlling the pressure display unit 400. 【0035】 Figure 4 is a diagram showing the color change of the pressure indicator in a handpiece for a skin aesthetic device according to one embodiment of the present invention, in accordance with the pressure applied to the user's skin. 【0036】 As shown in Figure 4, by increasing the pressure exerted on the user's skin (S) by the handpiece for a skin aesthetic device according to one embodiment of the present invention, the color of the pressure indicator 400 can change to yellow (Y), green (G), and red (R). When the color of the pressure indicator 400 is yellow (Y), it indicates that the pressure and deviation have not reached the reference range; when the color of the pressure indicator 400 is green (G), it indicates that the pressure and deviation are within the reference range; and when the color of the pressure indicator 400 is red (R), it indicates that the pressure and deviation have exceeded the reference range. 【0037】 In this embodiment, the pressure display unit 400 changed color to yellow (Y), green (G), and red (R), but it is not limited to these colors, and pressure changes can be displayed by changing to various other colors. 【0038】 Thus, the handpiece for a skin aesthetic device according to one embodiment of the present invention allows for visual confirmation of the pressure and deviation applied to the skin using the pressure display unit, enabling treatment to always be performed at the optimal pressure, regardless of the practitioner's or user's senses or experience. 【0039】 In other words, 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 effectiveness of the treatment. 【0040】 Furthermore, since the practitioner or user can immediately confirm the stability of the product on the skin, product reliability can be improved. 【0041】 On the other hand, in the above embodiment, the pressure sensing unit includes a plurality of pressure sensors, but other embodiments are also possible in which the pressure sensing unit includes an elastic assembly. 【0042】 The following describes in detail another embodiment of the present invention, specifically a handpiece for a skin aesthetic device, with reference to Figures 5 to 7. 【0043】 Figure 5 is a schematic plan view of a handpiece for a skin aesthetic device according to another embodiment of the present invention. 【0044】 The other embodiment shown in Figure 5 is substantially the same as the embodiment shown in Figure 1, except for the structure of the pressure sensing section, so a repeated explanation will be omitted. 【0045】 As shown in Figure 5, another embodiment of the present invention of a handpiece for a skin aesthetic device 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 can 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 deforms in response to the pressure applied to the skin (S) by the skin treatment unit 200. One elastic assembly 320 may include a multi-stage pogo pin, each stage of which is equipped with an elastic body 32 having a different elastic modulus. Hereinafter, the elastic assembly 320 will be described using a multi-stage pogo pin as an example. 【0047】 Figure 6 is a specific perspective view of the elastic assembly shown in Figure 5. 【0048】 As shown in Figure 6, the multi-stage pogo pin 320 may include an upper pogo pin 320u adjacent to the skin treatment area 200, a lower pogo pin 320d adjacent to the handpiece body 100, and a middle pogo pin 320m located between the upper pogo pin 320u and the lower pogo pin 320d. 【0049】 Here, the elastic modulus of the elastic bodies 32 mounted on the upper pogo pin 320u, the middle pogo pin 320m, and the lower pogo pin 320d can increase 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 bodies 32u, 32m, and 32d of the upper pogo pin 320u, the middle pogo pin 320m, and the lower pogo pin 320d can be made to correspond to a pre-set pressure standard. 【0050】 In other words, the elastic modulus of the upper elastic body 32u mounted on the upper pogo pin 320u may be below the predetermined pressure reference range, the elastic modulus of the middle elastic body 32m mounted on the middle pogo pin 320m may be within the pressure reference range, and the elastic modulus of the lower elastic body 32d mounted on the lower pogo pin 320d may exceed the pressure reference range. 【0051】 The pressure display unit 400 can emit light in multiple colors by deforming the length (L) of the elastic assembly 320. Such a pressure display unit 400 can be constructed using LEDs. 【0052】 The control unit 500 can transmit control signals resulting from the length deformation of the elastic assembly to the pressure display unit 400, thereby controlling the pressure display unit 400. 【0053】 Figure 7 is a diagram illustrating the color change of the pressure indicator in a handpiece for a skin aesthetic device, based on another embodiment of the present invention, due to the pressure applied to the user's skin. 【0054】 As shown in Figure 7, by increasing the pressure exerted on the user's skin (S) by a handpiece for a skin aesthetic device according to another embodiment of the present invention, the length of the elastic assembly 320 may change to L, L', and L'', and correspondingly the color of the pressure indicator 400 may change to yellow (Y), green (G), and red (R). When the color of the pressure indicator 400 is yellow (Y), it indicates that the pressure has not reached the standard range; when the color of the pressure indicator 400 is green (G), it indicates that the pressure has reached the standard range; and when the color of the pressure indicator 400 is red (R), it indicates that the pressure has exceeded the standard range. 【0055】 Although the present disclosure has been described above through preferred embodiments, those engaged in the art to which the present invention pertains will readily understand that the present invention is not limited thereto and that various modifications and variations are possible as long as they do not deviate from the scope of the claims described below.
