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] These home-use beauty treatment devices utilize high-intensity focused ultrasound (HIFU) technology to 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] However, as the medium temperature rises, its volume may increase. Furthermore, if water is used as the medium, freezing of the water in low-temperature environments, such as winter, can cause the medium's volume to increase. If the beauty treatment device breaks due to this increased volume, this can compromise the overall durability of the device and lead to serious functional problems, such as water leakage.

[0005] Therefore, there is an urgent need to develop a technology for a cosmetic treatment device that can accommodate the expansion pressure caused by the increase in the medium's temperature or the increase in the medium's volume due to the freezing of water.

[0006] The present invention has been conceived in consideration of the above points, and an object of the present invention is to provide a cosmetic treatment device capable of accommodating expansion pressure resulting from an increase in the volume of a medium due to an increase in the temperature of the medium.

[0007] In addition, another object of the present invention is to provide a cosmetic treatment device capable of accommodating expansion pressure due to an increase in the volume of a medium caused by freezing.

[0008] The problems to be solved by the present invention are not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by a person having ordinary skill in the technical field to which the present invention belongs from the description below.

[0009] According to one aspect of the present invention, a cosmetic treatment device is provided, including a main body that receives power from a power source and an ultrasonic generator that receives a signal from the main body and applies ultrasonic vibration to the outside through a medium, wherein the ultrasonic generator includes a housing that accommodates the medium, an ultrasonic vibrator coupled to the housing and that receives the signal, generates ultrasonic vibration, and transmits the ultrasonic vibration to the medium, and an elastic member arranged to cover at least a portion of the housing.

[0010] At this time, the cross-sectional area of ​​the housing may increase as it moves toward the main body from the ultrasonic generator.

[0011] At this time, the ultrasonic generator may further include a fixing member coupled to one side of the inside of the housing, and to which the ultrasonic vibrator is coupled.

[0012] At this time, the ultrasonic generator may further include a coupling member that is placed on one side of the housing and couples the main body and the ultrasonic generator.

[0013] At this time, an expansion hole is formed in the connecting member, the elastic member is connected to the expansion hole, and the elastic member can be expanded through the expansion hole.

[0014] At this time, the elastic member may be formed larger than the expansion hole.

[0015] At this time, the cross-section of the expansion hole may be rectangular.

[0016] At this time, the elastic member may be in the shape of a plate.

[0017] At this time, the material of the elastic member may be any one of silicone, nitrile butadiene rubber, and urethane.

[0018] At this time, the material of the housing may be any one of silicone, nitrile butadiene rubber, and urethane.

[0019] At this time, the medium may be water.

[0020] According to the above configuration, the cosmetic treatment device according to the present invention can accommodate the expansion pressure due to the increase in the volume of the medium caused by the increase in the temperature of the medium by having an elastic member that expands according to the increase in the volume of the medium.

[0021] In addition, the beauty treatment device according to the present invention can accommodate expansion pressure due to an increase in the volume of the medium caused by freezing of water by having an elastic member that expands according to an increase in the volume of the medium.

[0022] The effects of the present invention are not limited to the effects described above, and should be understood to include all effects that can be inferred from the detailed description of the present invention or the composition of the invention described in the claims.

FIG. 6 is a drawing showing a state of coupling between a coupling member and an elastic member of an ultrasonic generator according to an embodiment of the present invention. Hereinafter, a cosmetic treatment device according to an embodiment of the present invention will be described with reference to the drawings.

[0037] Referring to FIGS. 1 and 2, a cosmetic treatment device (1) according to one embodiment of the present invention may include a main body (100), an ultrasonic generator (200), a case (300), and an ultrasonic radiation unit (400).

[0038] The main body (100) can generate ultrasonic waves by supplying a signal to the ultrasonic generator (200).

[0039] At this time, the main body (100) can be supplied with power from a separate power supply source. The main body (100) can be supplied with power from the outside through a wire (110) and apply a signal to the ultrasonic generator (200). In addition, the main body (100) can be supplied with power through a separate battery (not shown) inside the main body (100) and apply a signal to the ultrasonic generator (200). That is, the main body (100) can be supplied with power using a battery (not shown) outside or inside the main body (100) as a power supply source and apply a signal to the ultrasonic generator (200).

[0040] The ultrasonic generator (200) can be coupled to the main body (100).

[0041] A medium (2) can be accommodated inside the ultrasonic generator (200) for applying ultrasonic vibration.

[0042] The received medium (2) can receive a signal from the main body (100) and apply ultrasonic vibration to the outside.

[0043] Specifically, when power is applied from the main body (100) to the ultrasonic generator (200), ultrasonic waves are generated in the ultrasonic generator (200). The ultrasonic waves generated in the ultrasonic generator (200) pass through the medium (2) to be received, and ultrasonic vibrations can be applied to the outside from the medium (2) to be received.

[0044] The medium (2) can be selected to be suitable for effectively transmitting ultrasonic energy to the outside.

[0045] At this time, in selecting the medium (2), the phase change of the medium (2) according to the temperature change of the medium (2) due to ultrasonic energy can be considered.

[0046] In addition, when selecting a medium (2), whether bubbles are generated in the medium (2), whether foreign substances are generated, whether rust is generated, the degree of focus formation, energy transfer efficiency, etc. can be considered.

[0047] As an example, the medium (2) may be oil or liquid paraffin, which has less problems with phase change.

[0048] As another example, the medium (2) may be water, taking into account hygroscopicity and energy transfer efficiency.

[0049] More preferably, the medium (2) may be degassed water to prevent bubble formation within the medium (2).

[0050] The case (300) is coupled to the main body (100). In addition, as shown in Fig. 2, an ultrasonic generator (200) can be accommodated inside the case (300).

[0051] By accommodating the ultrasonic generator (200) inside the case (300), the ultrasonic generator (200) can be protected from external shocks or vibrations.

[0052] An ultrasonic radiator (400) can be coupled to the front end of the case (300).

[0053] The ultrasonic emitter (400) can transmit ultrasonic vibrations applied from the ultrasonic generator (200) to the user's skin.

[0054] Ultrasonic vibrations may be transmitted through direct contact between the ultrasonic emitter (400) and the user's skin, or may be transmitted through a separation of the ultrasonic emitter (400) and the user's skin at a certain distance.

[0055] The shape of the ultrasonic radiator (400) can vary depending on the purpose of transmitting ultrasonic vibration to the user's skin.

[0056] For example, the cross-section of the ultrasonic radiation unit (400) may be circular to allow the medicine to penetrate well into the user's skin.

[0057] Below, the ultrasonic generator (200) will be described in detail.

[0058] A medium (2) can be accommodated inside the ultrasonic generator (200) for applying ultrasonic vibrations. In addition, the ultrasonic generator (200) can receive a signal from the main body (100) and apply ultrasonic vibrations to the outside through the medium (2).

[0059] The ultrasonic generator (200) may include a housing (210), an ultrasonic vibrator (220), a fixing member (230), an elastic member (240), and a coupling member (250).

[0060] First, let's explain the housing (210).

[0061] As shown in FIGS. 3 to 5, a space capable of accommodating a medium (2) may be provided inside the housing (210).

[0062] A medium (2) can be accommodated inside the housing (210) and ultrasonic vibration can be applied to the outside through the accommodated medium (2).

[0063] The housing (210) may include a portion whose cross-sectional area decreases as it moves away from the main body (100) at the contact surface with the main body (100). Since the direction in which ultrasonic waves are applied is forward, the housing (210) may include a portion whose cross-sectional area decreases as it moves forward.

[0064] The housing (210) may include a portion whose cross-sectional area is constant and whose cross-sectional area decreases as it moves away from the body (100) at the contact surface with the body (100). In addition, the housing (210) may have a cross-sectional area that decreases constantly as it moves away from the body (100) at the contact surface with the body (100).

[0065] As the cross-sectional area of ​​the housing (210) decreases in the forward direction, the ultrasonic waves generated by the ultrasonic generator (200) can be gathered in the forward direction. Accordingly, the ultrasonic waves generated by the ultrasonic generator (200) can be stably transmitted to the outside.

[0066] In addition, in this case, the cross-sectional area of ​​the housing (210) closer to the main body (100) is formed to be larger than the cross-sectional area of ​​the housing (210) farther from the main body (100), thereby increasing the area of ​​the elastic member (240) described later. As a result, the elastic member (240) can stably accommodate the expansion pressure resulting from the increase in the volume of the medium (2).

[0067] Next, the ultrasonic vibrator (220) will be described.

[0068] The ultrasonic vibrator (220) can be coupled to the housing (210) as shown in FIGS. 4 and 5.

[0069] The ultrasonic vibrator (220) can generate ultrasonic vibrations by receiving a signal supplied from the main body (100). The ultrasonic vibrations generated from the ultrasonic vibrator (220) can pass through the medium (2).

[0070] Ultrasonic waves generated from an ultrasonic vibrator (220) can pass through the received medium (2) and ultrasonic vibrations can be applied to the outside from the received medium (2).

[0071] The position at which the ultrasonic vibrator (220) is coupled to the housing (210) may vary depending on the purpose of use of the beauty treatment device (1).

[0072] As an example, in order to maximize the amount of ultrasound transmitted to the user's skin, an ultrasonic vibrator (220) may be coupled to the front end of the housing (210). In this case, ultrasound generated from the ultrasonic vibrator (220) may be effectively transmitted to the user's skin.

[0073] Next, the fixed member (230) will be described.

[0074] The fixed member (230) can be coupled to one side of the inside of the housing (210). In addition, an ultrasonic vibrator (220) can be coupled to the inside of the fixed member (230).

[0075] In this case, the ultrasonic vibrator (220) can be prevented from moving in accordance with the movement of the medium (2) contained inside the housing (210). In addition, since the ultrasonic vibrator (220) does not move in accordance with the tilt of the main body (100), the user can use the beauty treatment device (1) regardless of the degree to which the main body (100) is tilted.

[0076] The position at which the fixed member (230) is attached to the housing (210) may vary depending on the purpose of use of the beauty treatment device (1).

[0077] As an example, the fixing member (230) may be coupled to the front end of the housing (210) to maximize the amount of ultrasonic waves transmitted to the user's skin. In this case, ultrasonic waves generated from the ultrasonic vibrator (220) can be effectively transmitted to the user's skin with minimal energy loss.

[0078] Next, the elastic member (240) will be described.

[0079] As shown in FIGS. 3 to 6, the elastic member (240) can be arranged to cover at least a portion of the housing (210).

[0080] The elastic member (240) can accommodate various state changes occurring in the beauty treatment device (1).

[0081] That is, the elastic member (240) can offset shock and vibration occurring in the beauty treatment device (1) and accommodate an increase and decrease in the volume of the medium (2) due to temperature changes between high and low temperatures.

[0082] Specifically, the elastic member (240) may be expandable when the volume of the medium (2) contained inside the housing (210) increases.

[0083] When the beauty treatment device (1) is used, the temperature of the medium (2) contained within the housing (210) may rise, thereby increasing the volume of the medium (2) contained within the housing (210). In addition, when the medium (2) contained within the housing (210) is water, the volume of the medium (2) may increase due to freezing of the water.

[0084] The elastic member (240) can be used both in cases where the temperature of the received medium (2) increases and the volume of the medium (2) increases, and in cases where the volume of the medium (2) increases due to freezing of water.

[0085] The elastic member (240) must be able to expand when the volume of the medium (2) increases and then return to the state before expansion when the volume of the medium (2) decreases again.

[0086] For this purpose, the elastic member (240) may be made of a material capable of elastic deformation.

[0087] The material of the elastic member (240) may be any one of silicone, nitrile butadiene rubber, and urethane. In this case, the elastic member (240) is capable of elastic deformation, so that it expands when the volume of the medium (2) increases, and then returns to its pre-expanded state when the volume of the medium (2) decreases again.

[0088] The elastic member (240) can prevent damage to the cosmetic treatment device (1) due to an increase in the volume of the medium (2) by receiving the expansion pressure resulting from an increase in the volume of the medium (2).

[0089] Since the elastic member (240) can accommodate the expansion pressure due to the increase in the volume of the medium (2), the user can use the medium (2) by filling the inside of the housing (210) with the medium (2).

[0090] Since the medium (2) is filled inside the housing (210), an air layer other than the medium (2) cannot be located in front of the ultrasonic vibrator (220). And since there is no air layer inside the medium (2), the user can use the beauty treatment device (1) regardless of how the beauty treatment device (1) is tilted.

[0091] Therefore, since the beauty treatment device (1) includes an elastic member (240), it is possible to prevent the user from being burned due to the air layer existing in front of the ultrasonic vibrator (220). In addition, it is possible to prevent ultrasonic vibrations from not being emitted due to the air layer existing in front of the ultrasonic vibrator (220).

[0092] As described above, the housing (210) may include a portion whose cross-sectional area decreases as it moves away from the main body (100) at the contact surface with the main body (100). Since the direction in which ultrasonic waves are applied is forward, the housing (210) may include a portion whose cross-sectional area decreases as it moves forward.

[0093] In this case, the cross-sectional area of ​​the housing (210) closer to the main body (100) is formed to be larger than the cross-sectional area of ​​the housing (210) farther from the main body (100), thereby increasing the area of ​​the elastic member (240) described later. As a result, the elastic member (240) can stably accommodate the expansion pressure resulting from the increase in the volume of the medium (2).

[0094] Additionally, the material of the housing (210) may be made of a material capable of elastic deformation.

[0095] At this time, the housing (210) can expand when the volume of the medium (2) increases and then return to the state before expansion when the volume of the medium (2) decreases again.

[0096] In this case, the housing (210) can be used both in cases where the temperature of the received medium (2) increases and the volume of the medium (2) increases, and in cases where the volume of the medium (2) increases due to freezing of water.

[0097] The material of the housing (210) may be any one of silicone, nitrile butadiene rubber, and urethane. In this case, the housing (210) is capable of elastic deformation, so that it expands when the volume of the medium (2) increases, and returns to its pre-expansion state when the volume of the medium (2) decreases.

[0098] Next, the joining member (250) will be described.

[0099] As illustrated in FIGS. 3 to 5, the coupling member (250) may be placed on one side of the housing (210). In addition, the main body (100) and the ultrasonic generator (200) may be coupled through the coupling member (250).

[0100] A joining hole (252) may be formed on one side of the joining member (250). The main body (100) and the ultrasonic generator (200) may be screw-joined through the joining hole (252).

[0101] A plurality of coupling holes (252) may be provided for screw coupling of the main body (100) and the ultrasonic generator (200). As an example, the coupling holes (252) may be formed at 90-degree intervals from the center of the coupling member (250).

[0102] In order to connect the main body (100) and the ultrasonic generator (200) through the connecting member (250), the connecting member (250) may be formed at the rear end of the main body (100).

[0103] As shown in Fig. 4, an expansion hole (251) can be formed in the joining member (250).

[0104] The elastic member (240) can be combined with the expansion hole (251). In this case, when the elastic member (240) expands, the elastic member (240) can expand through the expansion hole (251).

[0105] What is meant by the fact that the elastic member (240) can be expanded through the expansion hole (251) when the elastic member (240) expands means that the bond between the elastic member (240) and the expansion hole (251) is maintained even when the elastic member (240) expands.

[0106] At this time, as shown in Fig. 6, the elastic member (240) can be formed larger than the expansion hole (251).

[0107] Since the elastic member (240) is formed larger than the expansion hole (251), when the elastic member (240) expands, the elastic member (240) is not separated from the expansion hole (251) and can be stably maintained in a combined state with the expansion hole (251).

[0108] At this time, the elastic member (240) can be formed so as not to come into contact with the joining hole (252).

[0109] Since the elastic member (240) is formed so as not to come into contact with the joining hole (252), the expansion of the elastic member (240) may not cause interference with the joining hole (252).

[0110] The shape of the cross-section of the expansion hole (251) can be formed so that the elastic member (240) does not become detached from the expansion hole (251) when the elastic member (240) expands.

[0111] As an example, the cross-section of the expansion hole (251) may be formed into a square shape. In this case, by supporting an elastic member (240) at each vertex of the expansion hole (251), the joint state of the elastic member (240) and the expansion hole (251) can be stably maintained when the elastic member (240) expands. That is, by concentrating the stress due to the expansion of the elastic member (240) at the four vertices of the expansion hole (251), the joint state of the elastic member (240) and the expansion hole (251) can be stably maintained.

[0112] The shape of the elastic member (240) can be formed so that the elastic member (240) is stably combined with the joining hole (252).

[0113] As an example, the elastic member (240) may be in the form of a plate. In this case, stable shape changes are possible when the elastic member (240) expands and returns, so that the bonding state between the elastic member (240) and the expansion hole (251) can be stably maintained.

[0114] Additionally, the cross-section of the elastic member (240) may be formed into a square shape. In this case, the shape of the elastic member (240) is simple, making it easy to manufacture the elastic member (240).

[0115] Fig. 7 is a drawing showing a state in which a medium is accommodated inside an ultrasonic generator according to an embodiment of the present invention. Fig. 8 is a drawing showing a state in which the volume of a medium accommodated inside an ultrasonic generator according to an embodiment of the present invention has increased. Hereinafter, with reference to Figs. 7 and 8, a description will be given of a process for accommodating expansion pressure due to an increase in the volume of a medium (2) accommodated inside an ultrasonic generator (200).

[0116] As shown in Fig. 7, a fluid can be accommodated inside the ultrasonic generator (200).

[0117] When the beauty treatment device (1) is used, the temperature of the medium (2) contained within the housing (210) may rise, thereby increasing the volume of the medium (2) contained within the housing (210). In addition, when the medium (2) contained within the housing (210) is water, the volume of the medium (2) may increase due to freezing of the water.

[0118] As shown in Fig. 8, when the volume of the medium (2) increases, the elastic member (240) is capable of elastic deformation and can expand when the volume of the medium (2) increases.

[0119] In this way, the expansion pressure due to the increase in volume of the medium (2) contained inside the ultrasonic generator (200) can be accommodated through the elastic member (240).

[0120] When the volume of the increased medium (2) decreases, the elastic member (240) can be elastically deformed and thus can return to its original state. That is, it can return from the state of Fig. 8 to the state of Fig. 7.

[0121] By accommodating the expansion pressure resulting from the increase in the volume of the medium (2), damage to the cosmetic treatment device (1) due to the increase in the volume of the medium (2) can be prevented.

[0122] Additionally, the material of the housing (210) may be made of an elastically deformable material. In this case, when the volume of the medium (2) increases, the housing (210) is elastically deformable and can expand when the volume of the medium (2) increases.

[0123] When the volume of the increased medium (2) decreases, the housing (210) can be elastically deformed and thus can return to its original state.

[0124]
