Description

Beauty treatment device

[0001] The present invention relates to a beauty treatment device, and more particularly, to a beauty treatment device that performs a beauty treatment by coming into contact with a user's skin.

[0002] Recently, the popularity of home beauty treatment devices, which allow users to perform beauty treatments like hair removal and skin care at home, has been increasing. These devices lower the barrier to accessing beauty treatments and increase accessibility by allowing users to conveniently perform beauty treatments at their own home, at their own time.

[0003] Among these home-use beauty treatment devices, those using high-intensity focused ultrasound (HIFU) technology create a thermal focal point within skin tissue, resulting in lifting or tightening effects. Since ultrasound energy is transmitted as vibrations, a medium is required for this energy to propagate. This medium can be oil, liquid paraffin, or water.

[0004] The temperature of these media can be increased by ultrasonic vibration. However, this increase in media temperature can reduce the durability of components used for ultrasonic vibration.

[0005] The present invention is intended to solve the above problems, and an object of the present invention is to provide a cosmetic treatment device that smoothly disperses the heat of a medium and stably maintains ultrasonic performance.

[0006] The tasks of the present invention are not limited to the tasks mentioned above, and other tasks not mentioned will be clearly understood by those skilled in the art to which the present invention pertains from the description below.

[0007] According to one aspect of the present invention, a cosmetic treatment device may be provided, comprising: a housing; and an ultrasonic generator coupled to the housing and configured to receive an electrical signal from the housing and generate ultrasonic vibrations to the outside through a medium, wherein the ultrasonic generator comprises: a body portion in which the medium is accommodated; a bottom portion coupled to one side of the body portion; a bracket coupled to the housing and fixing the bottom portion to the housing; and a first heat transfer portion that transfers heat from the bottom portion to the bracket.

[0012] At this time, the first heat transfer unit may include a first thermal pad disposed between the support unit and the bracket; and a second thermal pad disposed between the support unit and the bracket and spaced apart from the first thermal pad.

[0013] At this time, the bottom portion may further include a receiving portion that receives an elastic member that expands to correspond to a change in the volume of the medium.

[0014] At this time, the heat of the medium can be transferred to the housing through the bottom portion, the first heat transfer portion, and the bracket.

[0015] At this time, the heat of the medium can be transferred to the housing through the extension and the second heat transfer portion.

[0031] Hereinafter, a cosmetic treatment device according to an embodiment of the present invention will be described with reference to the drawings.

[0032] FIG. 1 is a perspective view showing the appearance of a beauty treatment device according to an embodiment of the present invention, FIG. 2 is a perspective view showing an ultrasonic generator of a beauty treatment device according to an embodiment of the present invention separated from a housing, and FIG. 3 is a perspective view showing an ultrasonic generator of a beauty treatment device according to an embodiment of the present invention.

[0033] Referring to FIGS. 1 to 3, a cosmetic treatment device (100) according to an embodiment of the present invention includes a housing (110), an ultrasonic generator (200), and a cover (120).

[0034] The housing (110) may be formed into a roughly cylindrical shape. Furthermore, the housing (110) may be formed of aluminum. However, the housing (110) is not limited to being formed of aluminum, and may be formed of various materials with thermal conductivity, such as aluminum.

[0035] In addition, the housing (110) is provided with a control unit (not shown) that controls the ultrasonic generator (200) to generate ultrasonic vibration by applying an electrical signal to the ultrasonic generator (200).

[0036] At this time, the housing (110) can be supplied with external power through the terminal (150). Then, the control unit controls the ultrasonic generator (200) to generate ultrasonic vibration by applying an electrical signal through the external power.

[0037] In addition, the housing (110) may be equipped with a battery (not shown) that is charged through the terminal (150). In addition, the control unit may control the ultrasonic generator (200) to generate ultrasonic vibration by applying an electrical signal through the battery.

[0038] The ultrasonic generator (200) can be coupled with the housing (110). In addition, a portion of the ultrasonic generator (200) is accommodated inside the housing (110). At this time, a catch (130) is provided inside the housing (110) to catch the ultrasonic generator (200). In addition, the ultrasonic generator (200) is caught on the catch (130) and is stably fixed to the housing (110).

[0039] And, the ultrasonic generator (200) accommodates a medium for ultrasonic vibration. And, the medium can receive an electrical signal from the housing (110) and generate ultrasonic vibration to the outside.

[0040] Specifically, when an electrical signal is applied from the housing (110) to the ultrasonic generator (200), the ultrasonic generator (200) generates ultrasonic vibrations. Then, the ultrasonic vibrations generated from the ultrasonic generator (200) are transmitted to the outside through a medium.

[0041] In addition, the medium may be selected as suitable for effectively transmitting ultrasonic vibration energy to the outside. At this time, when selecting the medium, the phase change of the medium according to the temperature change of the medium due to ultrasonic vibration energy may be considered. In addition, when selecting the medium, the presence of bubbles, foreign substances, rust, degree of focus formation, energy transfer efficiency, etc. may be considered.

[0042] As an example, the medium may be oil or liquid paraffin, taking phase change into consideration.

[0043] As another example, the medium may be water, taking into account hygroscopicity and energy transfer efficiency.

[0044] As another example, the medium may be degassed water to prevent bubble formation.

[0045] The cover (120) accommodates the ultrasonic generator (200). In addition, the cover (120) is coupled to the housing (110). In addition, the cover (120) protects the ultrasonic generator (200) from external impact.

[0046] In addition, the cover (120), like the housing (110), may be made of aluminum. In addition, according to various embodiments of the present invention, the cover (120) may be made of an elastic material such as silicone, thereby alleviating discomfort caused by the cover (120) coming into contact with the user's skin.

[0047] Additionally, one side of the cover (120) can be opened so that the ultrasonic radiation unit (240) is exposed to the outside.

[0048] The above ultrasonic radiation unit (240) can transmit ultrasonic vibrations applied from the ultrasonic generation unit (200) to the user's skin.

[0049] At this time, the ultrasonic vibration can be transmitted when the ultrasonic radiator (240) directly contacts the user's skin, or can be transmitted to the user's skin when the ultrasonic radiator (240) is spaced a certain distance from the user's skin.

[0050] In addition, the end of the ultrasonic radiator (240) may be formed into a circular shape. Accordingly, when a medicine or cosmetic is applied to the user's skin, the circular end of the ultrasonic radiator (240) can stably ensure the absorption of the medicine or cosmetic by the user's skin.

[0051] However, the end of the ultrasonic radiator (240) is not limited to being formed in a circular shape, and may be formed in various shapes depending on the purpose of transmitting ultrasonic vibration to the user's skin.

[0052] Hereinafter, with reference to the drawings, the ultrasonic generator (200) will be described in detail.

[0053] FIG. 4 is a drawing schematically showing the main components of the ultrasonic generator of the beauty treatment device according to an embodiment of the present invention separated, FIG. 5 is a drawing focusing on the first heat transfer unit and the second heat transfer unit of the beauty treatment device according to an embodiment of the present invention, and FIG. 6 is a cross-sectional view showing the beauty treatment device according to an embodiment of the present invention.

[0054] As shown in FIGS. 3 to 6, the ultrasonic generator (200) includes a body (210), a bottom (230), and a bracket (220).

[0055] The medium is accommodated in the body portion (210). In addition, the cross-sectional area of ​​the body portion (210) decreases as it moves away from the housing (110). For example, the direction in which ultrasonic vibration is transmitted is forward, and the cross-sectional area of ​​the body portion (210) decreases along the forward direction.

[0056] The above body part (210) is equipped with an ultrasonic vibrator (not shown). The ultrasonic vibrator can generate ultrasonic vibrations by receiving an electrical signal.

[0057] The bottom part (230) is coupled to one side of the body part (210). In addition, the bottom part (230) receives the medium together with the body part (210). In addition, the bottom part (230) includes a support part (231), an extension part (233), and a receiving part (232).

[0058] The above support portion (231) is formed to correspond to one side of the body portion (210). Accordingly, the support portion (231) prevents the medium from leaking out from the body portion (210).

[0059] The above extension portion (233) extends from the support portion (231). At this time, the extension portion (233) may be formed integrally with the support portion (231). In addition, according to various embodiments of the present invention, the extension portion (233) may be formed separately from the support portion (231) and may be coupled to the support portion (231).

[0060] And, as shown in Fig. 6, the extension (233) faces the inner surface of the housing (110).

[0061] In addition, the extension part (233) has a curved surface corresponding to the inner surface of the housing (110). That is, the extension part (233) is caught on the inner surface of the housing (110), so that the ultrasonic generator (200) is stably fixed to the housing (110).

[0062] The above-mentioned receiving portion (232) is supported by the above-mentioned support portion (231). In addition, the receiving portion (232) may be formed in an approximately hexahedral shape. At this time, the receiving portion (232) is opened in the forward direction.

[0063] And, the receiving portion (232) receives an elastic member (250) that expands to correspond to a change in the volume of the medium. At this time, a catch portion (232b) on which the elastic member (250) is caught is formed in the receiving portion (232). The catch portion (232b) is spaced apart from the support portion (231) at a certain interval.

[0064] And, the elastic member (250) is caught on the catch (232b), so that a separation space (232a) is formed between the elastic member (250) and the support member (231).

[0065] Accordingly, the elastic member (250) can be expanded in the separation space (232a).

[0066] The above bracket (220) is coupled to the housing (110). In addition, the bracket (220) is coupled to the bottom portion (230) using a bolt connection method. That is, the bracket (220) serves to secure the bottom portion (230) to the housing (110).

[0067] At this time, the housing (110) is provided with a fixing protrusion (130) corresponding to the lower end of the bracket (220). The lower end of the bracket (220) is caught by the fixing protrusion (130), so that the ultrasonic generator (200) can be coupled to the housing (110).

[0068] In addition, the cosmetic treatment device according to an embodiment of the present invention includes a first heat transfer unit (270) that transfers heat of the bottom unit (230) to the bracket (220).

[0069] When the temperature of the body part (210) and the bottom part (230) increases due to the heat of the medium, there is a problem in that the performance of the ultrasonic generator (200) deteriorates.

[0070] To solve this, the first heat transfer unit (270) transfers the heat of the bottom unit (230) to the bracket (220). Then, the heat of the bracket (220) is transferred to the housing (110). Then, the first heat transfer unit (270) includes a first thermal pad (271) and a second thermal pad (272).

[0071] The above first thermal pad (271) is placed between the support member (231) and the bracket (220).

[0072] The second thermal pad (272) is disposed between the support portion and the bracket (220), and is spaced apart from the first thermal pad (271). At this time, as shown in FIGS. 5 and 6, the second thermal pad (272) is disposed spaced apart from the first thermal pad (271) with the receiving portion (232) interposed therebetween. Accordingly, the first thermal pad (271) and the second thermal pad (272) can prevent the generation of ultrasonic vibrations by minimizing temperature changes in the medium of the receiving portion (232) during the process of transferring heat from the bottom portion (230).

[0073] In addition, the cosmetic treatment device according to an embodiment of the present invention includes a second heat transfer unit (260) that transfers heat of the extension unit (233) to the housing (110).

[0074] The second heat transfer portion (260) covers one side of the extension portion (233) facing the inner surface of the housing (110).

[0075] In addition, since the second heat transfer part (260) is placed between the extension part (233) and the housing (110), the extension part (233) is stably fixed to the housing (110) through the second heat transfer part (260).

[0076] FIG. 7 is a drawing showing how heat of a medium of a beauty treatment device according to an embodiment of the present invention is transferred.

[0077] As illustrated in FIG. 7, the heat of the medium is transferred to the housing (110) through the first heat transfer unit (271, 272) or transferred to the housing (110) through the second heat transfer unit (260).

[0078] Specifically, the heat of the medium is transferred to the housing (110) through the bottom portion (230), the first heat transfer portion (271, 272), and the bracket (220).

[0079] And, the heat of the medium is transferred to the housing (110) through the extension (233) of the bottom portion (230) and the second heat transfer portion (260).

[0080] In addition, according to an embodiment of the present invention, the housing (110), the bottom part (230), and the bracket (220) may include an aluminum material. For example, the housing (110), the bottom part (230), and the bracket (220) may be made only of an aluminum material. In addition, according to various embodiments of the present invention, the parts where the housing (110), the bottom part (230), and the bracket (220) come into contact with each other may be made of an aluminum material.

[0081] In this way, since the housing (110), the bottom part (230), and the bracket (220) are made of aluminum, the effect of heat transfer of the medium to the housing (110) can be increased.

[0082] In addition, according to an embodiment of the present invention, the first heat transfer unit (271, 272) and the second heat transfer unit (260) may have a thermal conductivity of 1.0 W / mk to 5.0 W / mk. Accordingly, heat of the medium is prevented from accumulating inside the ultrasonic generator (200) and the performance of the ultrasonic generator (200) is prevented from deteriorating.

[0083] In addition, the first heat transfer unit (271, 272) and the second heat transfer unit (260) may be made of a silicone material. At this time, the first heat transfer unit (271, 272) and the second heat transfer unit (260) made of a silicone material may have a thermal conductivity of 1.0 W / mk to 5.0 W / mk, as described above.

[0084] Although the embodiments of the present invention have been described, the spirit of the present invention is not limited to the embodiments presented in this specification, and those skilled in the art who understand the spirit of the present invention will be able to easily propose other embodiments by adding, changing, deleting, or adding components within the scope of the same spirit, but this will also be considered to fall within the spirit of the present invention.
