Description

Device for beauty treatment}

The present invention relates to a cosmetic treatment device, and more specifically, to a cosmetic treatment device that contacts the user's skin to perform a cosmetic treatment.

In recent years, the prevalence of home beauty treatment devices that allow users to perform beauty treatments such as hair removal and skin care at home is increasing. Home cosmetic treatment devices lower barriers to cosmetic procedures and increase accessibility by allowing users to conveniently perform cosmetic procedures at their own home and at the time they want.

As the spread of home beauty treatment devices increases, the performance of home beauty treatment devices is improving dramatically compared to before, and the effectiveness of the treatment is also increasing. This means that the possibility of side effects occurring while a user performs a cosmetic procedure using the device has also increased. For example, home beauty treatment devices perform hair removal, massage, etc. through lasers, suction, etc., but if excessive laser irradiation or excessive suction is applied to the user's skin during use, burns, skin damage, etc. Side effects may occur.

In order to safely obtain the effects of using a home cosmetic treatment device without side effects, laser irradiation, suction, etc. must be performed appropriately. However, the appropriate laser irradiation intensity and irradiation amount, suction intensity, etc. vary depending on the user's skin elasticity, skin tone, etc. Therefore, in order to maximize the effect of the cosmetic treatment device and ensure safety, the appropriate irradiation intensity and dose of the laser, suction intensity, etc. need to be customized for each user.

Additionally, Figure 2 is a diagram briefly illustrating components disposed in the main body of the cosmetic treatment device according to the first embodiment of the present invention.

The cosmetic treatment device 100 according to the first embodiment of the present invention performs cosmetic treatment on the user's skin. More specifically, the cosmetic treatment device 100 according to the first embodiment of the present invention allows the user to directly perform cosmetic treatment on his or her skin. That is, the user can perform the cosmetic treatment on his/her own by contacting the cosmetic treatment device 100 according to the first embodiment of the present invention to his or her skin. For example, the cosmetic treatment device 100 according to the first embodiment of the present invention may provide a suction function for massaging the user's skin.

1 and 2, the cosmetic treatment device 100 according to the first embodiment of the present invention includes a main body 110, a sound pressure provider 120, a pressure measurement unit 130, and a time measurement unit 140. , may include a skin elasticity calculation unit 150 and a control unit 160.

The main body 110 has a shape that can contact a predetermined area of the user's skin. A negative pressure providing unit 120, a pressure measuring unit 130, a time measuring unit 140, a skin elasticity calculating unit 150, and a control unit 160 may be disposed in the main body 110. The main body 110 provides a space where these components can be placed.

The main body 110 has an intake port 111. The sound pressure provided by the sound pressure provider 120 may be transmitted to the user's skin through the suction port 111. In the first embodiment of the present invention, the main body 110 has an opening 112 that contacts the user's skin, and the suction port 111 may be disposed adjacent to the opening 112. For example, the intake port 111 may be formed on the edge of the opening 112. In more detail, the opening 112 is formed wider than the suction port 111, and the suction port 111 may be formed as a small hole on the edge of the opening 112. Accordingly, when negative pressure is provided through the suction port 111, the user's skin may be sucked into the inside of the main body 110 mainly through the opening 112 by the negative pressure.

The negative pressure provider 120 provides negative pressure through the suction port 111. The sound pressure provider 120 may be disposed inside the main body 110. In the first embodiment of the present invention, the negative pressure providing unit 120 may include a pump that generates negative pressure. For example, the pump can be a pneumatic pump.

A suction function that sucks the user's skin toward the main body 110 may be provided by the sound pressure provided by the sound pressure provider 120. In other words, the cosmetic treatment may include suction in which the user's skin is sucked into the inside of the main body 110 by the negative pressure.

The pressure measuring unit 130 measures the internal pressure of the main body 110. The pressure measuring unit 130 may measure the internal air pressure of the main body 110 when sound pressure is provided by the sound pressure providing unit 120. The pressure measuring unit 130 may be disposed inside the main body 110. Additionally, the pressure measuring unit 130 may include a pressure sensor, etc.

As described above, when sound pressure is provided by the sound pressure provider 120 while the user's skin is in contact with the opening 112 of the main body 110, the user's skin is sucked into the inside of the main body 110. Specifically, the user's skin is sucked into the suction port 111 and the opening 112 of the main body 110, and the suction port 111 and the opening 112 are blocked by the user's skin, thereby preventing the user from entering the main body 110. Air inflow is blocked. Accordingly, negative pressure is formed inside the main body 110. At this time, the pressure measuring unit 130 can measure the sound pressure formed inside the main body 110.

The time measuring unit 140 measures the time it takes for the user's skin to be sucked into the inside of the main body 110 according to the provision of the sound pressure and the pressure measured by the pressure measuring unit 130 to reach a preset reference pressure. Measure time. The time measuring unit 140 may be disposed inside the main body 110. Additionally, the time measuring unit 140 may include a timer, etc.

Here, the reference pressure may be any negative pressure. When the user's skin is sucked into the main body 110 during suction, negative pressure begins to form inside the main body 110, and after the suction port 111 and the opening 112 are closed by the user's skin, the negative pressure The absolute value can reach a maximum. The reference pressure may be set as the pressure when the absolute value of the sound pressure reaches the maximum after the suction port 111 and the opening 112 are closed by the user's skin. The reference pressure may vary depending on the size and shape of the internal space of the main body 110, the performance of the sound pressure provider 120, etc.

The skin elasticity calculation unit 150 calculates the user's skin elasticity based on the time required by the time measurement unit 140. The skin elasticity calculation unit 150 may be disposed inside the main body 110. The skin elasticity calculation unit 150 may include one or more processors, memory elements, etc. that can store and process data.

The skin elasticity calculation unit 150 may calculate the user's skin elasticity using the pressure measurement information of the pressure measurement unit 130 and the time measurement information of the time measurement unit 140. When the opening 112 of the main body 110 comes into contact with the user's skin and the sound pressure provider 120 starts providing sound pressure, the user's skin is sucked into the main body 110 by the sound pressure. At this time, the higher the skin elasticity, the greater the resistance to being sucked into the inside of the main body 110. Therefore, the higher the skin elasticity, the slower the closure of the suction port 111 and the opening 112 by the user's skin, and accordingly, it takes a relatively long time for the internal pressure of the main body 110 to reach the reference pressure. This is required. The skin elasticity calculation unit 150 can calculate the user's skin elasticity based on this phenomenon.

The skin elasticity calculation unit 150 can calculate the skin elasticity at a high level in proportion to the time required. That is, the skin elasticity calculation unit 150 can calculate the skin elasticity on a continuous scale in proportion to the time required. At this time, skin elasticity can be calculated as an absolute elastic modulus or a relative value within a predetermined value range (for example, an arbitrary value selected from 0 to 10).

Alternatively, the skin elasticity calculation unit 150 may calculate the skin elasticity as a value selected from two or more categories (for example, any one of three categories: upper, middle, and lower). For example, the skin elasticity calculation unit 150 may calculate the skin elasticity based on the time intervals divided into two or more and the skin elasticity value set for each time interval. For example, the time required is divided into three sections, the skin elasticity of the section with the shortest time is low, the skin elasticity of the section with the longest time is high, and the skin elasticity of the section with the longest time is high, and the skin elasticity of the section with the longest time is high. Skin elasticity can be calculated as a medium.

The controller 160 controls the intensity of cosmetic treatment based on the skin elasticity. The control unit 160 may be placed inside the main body 110. In the first embodiment of the present invention, the control unit 160 may control the sound pressure providing unit 120, the pressure measuring unit 130, the time measuring unit 140, and the skin elasticity calculating unit 150. The control unit 160 may include one or more processors, memory elements, etc. capable of storing and processing data.

The controller 160 may set the intensity of the cosmetic treatment to be high in proportion to the skin elasticity. When the skin elasticity is relatively high, the skin can be considered healthy, so the control unit 160 can set the intensity of the cosmetic treatment to be high. Meanwhile, when the skin elasticity is relatively low, the health of the skin can be considered low, so the control unit 160 can minimize side effects by setting the intensity of the cosmetic treatment low.

In the first embodiment of the present invention, the intensity of the cosmetic treatment may include the intensity of the sound pressure provided by the sound pressure provider 120. As discussed above, the cosmetic treatment performed by the cosmetic treatment device 100 according to the first embodiment of the present invention may be suction through the negative pressure generated by the negative pressure provider 120. Suction provides a massage effect to the user's skin. In this regard, the control unit 160 may adjust the intensity of the sound pressure provided by the sound pressure provider 120 so that an appropriate level of suction is achieved according to the skin elasticity. Specifically, the controller 160 may set the intensity of the sound pressure to be high when the skin elasticity is relatively high, and may set the intensity of the sound pressure to be low when the skin elasticity is relatively low.

Hereinafter, the operation of the cosmetic treatment device 100 according to the first embodiment of the present invention will be described in more detail with reference to the related drawings.

Figure 3 is a diagram illustrating a process of setting the intensity of a cosmetic treatment in a cosmetic treatment device according to the first embodiment of the present invention. In addition, Figure 4 is a diagram illustrating the results of pressure measurement by the pressure measuring unit of the cosmetic treatment device according to the first embodiment of the present invention.

Referring to Figures 3 and 4, first, when the user's skin is in contact with the opening 112 of the main body 110, the sound pressure provider 120 provides sound pressure, which is measured by the pressure measurement unit 130. Negative pressure is provided until the pressure reaches the preset reference pressure (S110). That is, suction is performed until the internal pressure of the main body 110 reaches a preset reference pressure.

Next, as the time measuring unit 140 provides the sound pressure, the user's skin is sucked into the inside of the main body 110, and the pressure measured by the pressure measuring unit 130 reaches a preset reference pressure. Measure the time taken (S130). As discussed above, the reference pressure may be set to the pressure (sound pressure) when the absolute value of the sound pressure reaches the maximum after the suction port 111 and the opening 112 are closed by the user's skin.

Next, the skin elasticity calculation unit 150 calculates the user's skin elasticity using the pressure measurement information of the pressure measurement unit 130 and the time measurement information of the time measurement unit 140 (S150). When the opening 112 of the main body 110 comes into contact with the user's skin and the provision of the sound pressure begins, the user's skin is sucked into the inside of the main body 110 by the sound pressure. After the skin elasticity calculator 150 starts providing negative pressure, the suction port 111 and the opening 112 are closed by the user's skin until the internal pressure (absolute negative pressure) of the main body 110 reaches the reference pressure. Skin elasticity can be calculated based on the time taken.

Referring to FIG. 4, in the case of the first user (P1) whose skin elasticity is relatively low, the skin is easily sucked and the suction port 111 and the opening 112 are closed quickly, and at the first time point (t1) the main body ( 110) The internal pressure reaches the above reference pressure. In comparison, in the case of the second user (P2), whose skin elasticity is relatively high, the skin is sucked in late and the suction port 111 and the opening 112 are closed relatively late, and the first time point (t1) is later than the first time point (t1). At time t2, the internal pressure of the main body 110 reaches the reference pressure.

The skin elasticity calculation unit 150 calculates the skin elasticity at a relatively low level for the first user (P1) whose internal pressure of the main body 110 reaches the reference pressure at the first time point (t1). Meanwhile, the skin elasticity is calculated to be relatively high for the second user (P2) whose internal pressure of the main body 110 reaches the reference pressure at the second time point (t2), which is later than the first time point (t1).

Meanwhile, in the suction process for calculating skin elasticity, when the reference pressure is reached, the sound pressure provider 120 may stop providing sound pressure. As a result, the user's skin is restored by elasticity and escapes to the outside of the main body 110. As a result, the intake port 111 and the opening 112 are opened, and the absolute value of the internal sound pressure of the main body 110 decreases. . At this time, the higher the skin elasticity, the faster the skin is restored, so the maintenance time of the reference pressure (which can be said to be the time during which the user's skin maintains the state of closing the suction port 111 and the opening 112) appears short. Referring to FIG. 4, in the case of a first user (P1) with low skin elasticity, the provision of negative pressure is stopped after reaching the reference pressure at the first time point (t1), and the main body 110 is stopped at the third time point (t3). The internal pressure (absolute value of sound pressure) was found to be lower than the reference pressure. Meanwhile, in the case of the second user (P2) with high skin elasticity, the provision of negative pressure is stopped after reaching the reference pressure at the second time point (t2), and the internal pressure (sound pressure) of the main body 110 is increased at the fourth time point (t4). The absolute value of) was found to be lower than the above reference pressure. At this time, it can be seen that the length from the first time point (t1) to the third time point (t3) is longer than the length from the second time point (t2) to the fourth time point (t4).

Based on the above phenomenon, the skin elasticity calculation unit 150 may use the maintenance time of the standard pressure as the basis for calculating skin elasticity, assuming that the provision of negative pressure is stopped after the standard pressure is reached. Additionally, the skin elasticity calculation unit 150 may calculate the skin elasticity by considering the time required to reach the reference pressure and the maintenance time of the reference pressure.

Finally, the control unit 160 sets the intensity of the cosmetic treatment based on the skin elasticity (S170). As described above, the cosmetic treatment performed by the cosmetic treatment device 100 according to the first embodiment of the present invention may include suction. In this case, the control unit 160 can adjust the intensity of suction, that is, the intensity of sound pressure provided by the sound pressure provider 120.

The controller 160 may set the intensity of the cosmetic treatment to be high in proportion to the skin elasticity. The control unit 160 sets the intensity of the cosmetic treatment high for the second user (P2) with relatively high skin elasticity, and sets the intensity of the cosmetic treatment low for the first user (P1) with relatively low skin elasticity. You can set it.
