The beauty head is equipped with a first contact point and a first sensor, while the handheld component is equipped with a second contact point and a capacitive touch detection circuit. Since the first contact point is connected to the first sensor, and the second contact point is connected to the capacitive touch detection circuit, and since the first and second contact points can engage when the beauty head is mounted on the handheld component, when the beauty head is mounted on the handheld component, the second contact point engages with the first contact point of the beauty head, thereby establishing a pathway between the capacitive touch detection circuit and the first sensor. When the pathway between the capacitive touch detection circuit and the first sensor is established, the capacitive touch detection circuit can generate an in-situ electrical signal, thereby determining that the beauty head is mounted on the handheld component based on this in-situ electrical signal. The above solution, by configuring a first contact point and a first sensor connected in the beauty head, and a second contact point and a capacitive touch detection circuit connected in the handheld component, allows the first and second contact points to make contact when the beauty head is mounted on the handheld component, thereby establishing a path between the capacitive touch detection circuit and the first sensor. Here, the capacitive touch detection circuit and the first sensor are used to identify whether the beauty head is in contact with the skin. By generating an in-situ electrical signal when the capacitive touch detection circuit establishes a path with the first sensor, the touch detection circuit and the first sensor in the beauty head can be reused. That is, the in-situ detection between the beauty device body and the beauty head can be completed using the touch detection circuit in the beauty device body and the first sensor in the beauty head. Since the beauty device can only operate after the in-situ detection is completed, it avoids the beauty device operating under conditions of poor contact between the beauty head and the beauty device body, improving the user experience and ensuring the lifespan of the beauty device.

[0033] In order to make the technical problems to be solved by the present application, technical solutions and beneficial effects clearer, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0034] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0035] It should be understood that the terms "length", "width", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the present application and simplify the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0036] In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can be explicitly or implicitly configured with one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise explicitly and specifically limited.

[0037] With the increasing demand for skin care, users have increasingly rich functional requirements for beauty instruments. In order to enable the beauty instrument to meet the different functional requirements of the user, the beauty instrument body and the functional beauty head can be designed to be detachable.

[0038] However, in actual use, the user needs to manually install the beauty head on the beauty instrument main body for use. If the docking direction is wrong when the beauty head is docked with the beauty instrument main body, or there are contaminants, rust, etc. at the docking position of the two, it is easy to cause the beauty instrument to be unable to use, or the beauty instrument to be damaged due to poor contact between the beauty head and the beauty instrument main body, which not only affects the user experience, but also affects the service life of the beauty instrument.

[0039] To solve the above technical problems, the embodiment of the present application provides a beauty instrument which is configured with a handheld assembly and a beauty head, and the beauty head is detachably arranged with the handheld assembly. Wherein, the beauty head is configured with a first connection contact and a first sensing element, and the handheld assembly is configured with a second connection contact and a capacitive touch detection circuit. Since the first connection contact is connected with the first sensing element, and the second connection contact is connected with the capacitive touch detection circuit, and because the first contact point and the second contact point can cooperate and contact when the beauty head is installed on the handheld assembly, when the handheld assembly is installed with the beauty head, the second connection contact cooperates and contacts with the first connection contact of the beauty head, thereby conducting the path between the capacitive touch detection circuit and the first sensing element. When the path between the capacitive touch detection circuit and the first sensing element is conducted, the capacitive touch detection circuit can generate an in-place electrical signal, so that it can be determined that the handheld assembly has installed the beauty head according to the in-place electrical signal.

[0040] The above scheme, by configuring the first connection contact and the first sensing element connected in the beauty head, configuring the second contact point and the capacitive touch detection circuit connected in the handheld assembly, when the beauty head is installed on the handheld assembly, the first contact point and the second contact point cooperate and contact, thereby conducting the path between the capacitive touch detection circuit and the first sensing element. Here, the capacitive touch detection circuit and the first sensing element are used to identify whether the beauty head is in contact with the skin, and by causing the capacitive touch detection circuit to generate an in-place electrical signal when the path between the capacitive touch detection circuit and the first sensing element is conducted, the multiplexing of the touch detection circuit and the first sensing element in the beauty head can be realized. That is, by using the touch detection circuit in the beauty instrument main body and the first sensing element in the beauty head, the in-place detection between the beauty instrument main body and the beauty head can be completed. Since the beauty instrument can only work after completing the in-place detection, the beauty instrument can be prevented from working in the case that the beauty head and the beauty instrument main body are in poor contact, which not only improves the user experience, but also ensures the service life of the beauty instrument.

[0041] Reference Figure 1 , Figure 1 A structure schematic diagram of a beauty instrument provided by the embodiment of the present application is shown. For ease of illustration, only parts related to the present embodiment are shown, which are described in detail as follows:

[0042] InFigure 1 In the embodiment, the cosmetic instrument 300 is configured with the handheld assembly 100 and the cosmetic head 200 detachably arranged on the handheld assembly 100. Specifically,

[0043] The cosmetic head 200 is configured with the first connecting contact 210 and the first sensing element 220. The first connecting contact 210 is connected with the first sensing element 220.

[0044] The handheld assembly 100 is configured with the second connecting contact 110 and the capacitive touch detection circuit 120. The second connecting contact 110 is connected with the capacitive touch detection circuit 120. The second connecting contact 110 is used to contact the first connecting contact 210 of the cosmetic head 200 when the cosmetic head 200 is mounted on the handheld assembly 100, so as to turn on the path between the capacitive touch detection circuit 120 and the first sensing element 220. The capacitive touch detection circuit 120 is used to generate an in-place electric signal when the path between the capacitive touch detection circuit 120 and the first sensing element 220 is turned on, and the in-place electric signal is used to determine that the handheld assembly 100 has mounted the cosmetic head 200. The capacitive touch detection circuit 120 and the first sensing element 220 are also used to identify whether the cosmetic head 200 is attached to the skin.

[0045] In the embodiment, the first connecting contact 210 arranged on the cosmetic head 200 cooperates with the second connecting contact 110 arranged on the handheld assembly 100. When the cosmetic head 200 is mounted on the handheld assembly 100, the first connecting contact 210 and the second connecting contact 110 are in contact to form an electrical connection. Since the first sensing element 220 in the cosmetic head 200 is connected with the first connecting contact 210, and the capacitive touch detection circuit 120 in the handheld assembly 100 is connected with the second connecting contact 110, when the first connecting contact 210 and the second connecting contact 110 are in contact, the path between the first sensing element 220 and the capacitive touch detection circuit 120 is turned on, and at this time, a loop is formed, and the capacitive touch detection circuit 120 can generate an in-place electric signal for determining that the handheld assembly 100 has mounted the cosmetic head 200.

[0046] In all embodiments of the present application, the first connecting contact 210 generally refers to an electrical connecting contact for cooperating with the second connecting contact 110. The first sensing element 220 is connected with the first connecting contact 210, specifically, the first sensing element 220 is connected in the loop of the first connecting contact 210.

[0047] In specific implementation, the first connecting contact 210 can be an electrical connecting contact exposed at the connection of the cosmetic head 200, and correspondingly, the second connecting contact 110 can be an electrical connecting contact exposed at the connection of the handheld assembly. For example, the first connecting contact 210 can be a metal pin, and correspondingly, the second connecting contact 110 can be a metal slot matched with the metal pin.

[0048] For example, the first connecting contact 210 is configured with two metal pins, and the second connecting contact 110 is correspondingly configured with two metal slots. The first sensing member 220 is connected between the two metal pins to form a conductive branch in the beauty head 200. When the beauty head 200 is installed on the handheld assembly 100, the two metal pins of the beauty head 200 are electrically connected with the two metal slots in the handheld assembly 100. At this time, the conductive branch is connected with the capacitive touch detection circuit 120 through the two metal slots, so that the capacitive touch detection circuit 120 generates an in-place electrical signal. Here, the in-place electrical signal can be a level signal, such as a low level signal, a high level signal, or a conductive signal.

[0049] It is easy to understand that, since the capacitive touch detection circuit 120 is arranged in the handheld assembly 100, in actual use, the capacitive touch detection circuit 120 can be in a power-on state when the handheld assembly is powered on.

[0050] As an example, the capacitive touch detection circuit 120 can carry a certain voltage through the second connecting contact 110.

[0051] In one example, when the beauty head 200 is installed on the handheld assembly 100, since the first connecting contact 210 is in contact with the second connecting contact 110, the conductive branch where the first connecting contact 210 is located pulls down the voltage of the second connecting contact 110, and then the capacitive touch detection circuit 120 outputs a low level as an in-place electrical signal.

[0052] As another example, the capacitive touch detection circuit 120 can carry a certain voltage through the second connecting contact 110. Assuming that the second connecting contact 110 is configured with two contact electrodes or two metal slots, one contact electrode or one metal slot carries a voltage. When the beauty head 200 is installed on the handheld assembly 100, since the first connecting contact 210 is in contact with the second connecting contact 110, the voltage carried by one contact electrode or one metal slot is transmitted to the other contact electrode or the other metal slot through the conductive branch where the first connecting contact 210 is located, and then the capacitive touch detection circuit 120 outputs a high level as an in-place electrical signal.

[0053] In this embodiment, the first sensing member 220 also serves as a sensing member, i.e., a touch electrode; the capacitive touch detection circuit 120 and the sensing member are used to identify whether the beauty head 200 is attached to the skin.

[0054] Specifically, the first sensing member 220 can be regarded as a touch electrode of the capacitive touch detection circuit 120 as a sensing member. The first sensing member 220 can be a metal conductor, such as a sheet conductor, or a conductive part formed on a flexible printed circuit (FPC). When the beauty head 200 is mounted on the handheld assembly 100, a path between the capacitive touch detection circuit 120 and the first sensing member 220 is conducted, and thus the first sensing member 220 is conducted with the ground, thereby generating an in-place signal. It can be understood that after the path between the capacitive touch detection circuit 120 and the first sensing member 220 is conducted, the first sensing member 220 can carry a certain amount of electric charge. When no other conductor contacts the first sensing member 220, the capacitive touch detection circuit 120 detects a relatively constant value.

[0055] The skin can be regarded as a conductor. During the process that the beauty head 200 approaches the skin until contact, the amount of electric charge carried by the first sensing member 220 continuously changes due to the continuous approach of the skin, so that the capacitive touch detection circuit 120 can detect the change of the amount of electric charge carried by the first sensing member 220, and thus can be used to identify whether the beauty head 200 is attached to the skin.

[0056] In a specific implementation, the capacitive touch detection circuit 120 can be specifically configured with a sampling branch and an amplification branch. For example, the sampling branch is connected with the second connection contact 110, and thus the first sensing member 220 can be voltage-sampled when the path between the capacitive touch detection circuit 120 and the first sensing member 220 is conducted. Then the sampled voltage is amplified through the amplification branch, and thus an amplified voltage is obtained, which is used as a basis for identifying whether the beauty head 200 is attached to the skin.

[0057] In the embodiment, the first sensing member 220 also serves as a sensing member, which is equivalent to multiplexing the first sensing member 220. That is, the first sensing member 220 can serve as a conductive branch in the beauty head 200 when the beauty head 200 is mounted on the handheld assembly 100, and can affect the electrical signal of the second connection contact 110, so that the capacitive touch detection circuit 120 can generate an in-place electrical signal. At the same time, after the path between the first sensing member 220 and the capacitive touch detection circuit 120 is conducted, the first sensing member 220 can serve as a sensing member. During the process that the beauty head 200 approaches the skin until contact, the amount of electric charge carried by the first sensing member 220 as a sensing member continuously changes due to the continuous approach of the skin, so that the capacitive touch detection circuit 120 can detect the change of the amount of electric charge carried by the first sensing member 220, and use it as a basis for identifying whether the beauty head 200 is attached to the skin.

[0058] The above scheme is configured with the first connection contact and the first sensing element in the beauty head, and the second contact and the capacitive touch detection circuit in the handheld assembly. When the beauty head is installed on the handheld assembly, the first contact and the second contact are in contact, so as to turn on the path between the capacitive touch detection circuit and the first sensing element. Here, the capacitive touch detection circuit and the first sensing element are used to identify whether the beauty head is attached to the skin. By generating an in-place electrical signal when the capacitive touch detection circuit is turned on, the multiplexing of the touch detection circuit and the first sensing element in the beauty head can be realized. That is, the in-place detection between the beauty head and the beauty head can be completed by using the touch detection circuit in the beauty head and the first sensing element in the beauty head. Since the beauty instrument can only work after in-place detection is completed, the beauty instrument can be prevented from working in the case that the beauty head and the beauty instrument body are not in good contact, which not only improves the user experience, but also ensures the service life of the beauty instrument.

[0059] Figure 2 The structure of the beauty instrument provided by another embodiment of the present application is shown. As an embodiment, in Figure 2 the beauty head 200 is also configured with at least one second sensing element 230 spaced from the first sensing element. The capacitive touch detection circuit 120 and the first sensing element 220 and the at least one second sensing element 230 are used to identify whether the beauty head 200 is attached to the skin.

[0060] In this embodiment, the second sensing element 230 is spaced from the first sensing element, that is, the second sensing element 230 is spaced from the first sensing element 220. In addition, the second sensing element 230 can be connected to the capacitive touch detection circuit 120 through another connection contact combination (such as a fifth connection contact provided on the beauty head and electrically connected to the second sensing element, and a sixth connection contact provided on the handheld component and connected to the capacitive touch detection circuit 120).

[0061] In specific implementation, the second sensing element 230 can be the same conductor as the first sensing element 220, such as a metal conductor or a conductive part on an FPC.

[0062] Correspondingly, the second sensing element 230 can also form a conductive branch with at least two fifth connection contacts. As the first sensing element 220, during the process of the beauty head 200 approaching the skin until contacting, the amount of charge carried by the second sensing element 230 continuously changes due to the continuous approach of the skin, so that the capacitive touch detection circuit 120 can detect the change of the amount of charge carried by the first sensing element 220 and the second sensing element 230, respectively, and then be used to identify whether the beauty head 200 is attached to the skin.

[0063] In the embodiment, since the second induction piece is arranged in a spaced manner with the first induction piece (the first induction piece), the second induction piece can also be arranged in a similar manner with the first induction piece to be exposed on the surface of the beauty head. Specifically, the second induction piece can be arranged on the surface of the beauty head that acts on the skin.

[0064] It can be understood that, by arranging the second induction piece in a spaced manner with the first induction piece on the beauty head, the second induction piece can form an induction electrode together with the first induction piece, that is, the beauty head is considered to be attached to the skin only when the first induction piece and the second induction piece both detect the skin, so that the accuracy of identifying whether the beauty head is attached to the skin can be improved.

[0065] Figure 3 A structure diagram of a beauty instrument according to another embodiment of the present application is shown. Compared with the embodiment shown in FIG. 1, the difference lies in that, Figure 2 Figure 3 In the embodiment shown, the beauty instrument 300 is further configured with a prompt unit 130. Specifically, the prompt unit 130 is configured to output prompt information for indicating that the beauty head 200 is successfully mounted on the handheld assembly 100 when the beauty head 200 is mounted on the handheld assembly 100.

[0066] For example, the prompt unit 130 can be connected with the capacitive touch detection circuit 120, or the prompt unit 130 can be connected with the second connection contact 110, which is not limited herein.

[0067] In a specific implementation, the prompt unit 130 can be configured with a prompt light, a buzzer, etc. For example, the prompt unit 130 is configured with a prompt light, and the prompt light outputs blue light or green light when the beauty head 200 is mounted on the handheld assembly 100, to indicate that the beauty head 200 is successfully mounted.

[0068] For another example, the prompt unit 130 is configured with a buzzer, and the buzzer buzzes for N times (for example, 2 times or 3 times) when the beauty head 200 is mounted on the handheld assembly 100, to indicate that the beauty head 200 is successfully mounted.

[0069] In the embodiment, the prompt unit is configured to output prompt information when the handheld assembly is mounted with the beauty head, so that the user can know that the handheld assembly is mounted with the beauty head, and the prompt unit can indicate the user to take the next control operation in time, so as to improve the user experience and increase the user stickiness.

[0070] Figure 4 A structure diagram of a beauty instrument according to another embodiment of the present application is shown. Compared with the embodiment shown in FIG. 1, the difference lies in that, Figure 3 Figure 4 In the embodiment shown, as an embodiment, the beauty instrument 300 is further configured with a control host 10. Specifically:

[0071] ​​The control host 10 is electrically connected with the handheld assembly 100. The control host 10 is configured to connect a power supply, and convert power provided by the power supply to supply power to the handheld assembly 100.

[0072] In the embodiment, the control host 10 can have a power conversion function, such as an inverter function, a rectifier function, etc. In actual use, the power supply can be a power supply providing direct current or a city power supply providing alternating current. In specific implementation, the control host 10 can be configured with an inverter circuit and / or a rectifier circuit.

[0073] As an example, it is assumed that the working power of the beauty head 200 is alternating current. If the control host 10 is connected with a power supply providing direct current, the direct current provided by the power supply can be inverted by the inverter circuit, and then the working alternating current required by the beauty head 200 is provided by the handheld assembly 100.

[0074] As another example, it is assumed that the working power of the beauty head 200 is direct current. If the control host 10 is connected with a city power supply, the alternating current provided by the city power supply can be rectified by the rectifier circuit, and then the working direct current required by the beauty head 200 is provided by the handheld assembly 100.

[0075] As an example, taking the city power supply as an example, the control host 10 can convert the alternating current output by the city power supply to direct current, then convert the voltage of the direct current, and then output a first direct current voltage through the first power supply branch and a second direct current voltage through the second power supply branch. For example, the first direct current voltage output by the first power supply branch can be a direct current voltage with a voltage value in the range of 3-30V, and the second direct current voltage output by the second power supply branch can be a direct current voltage with a voltage value equal to or greater than 300V.

[0076] It is easy to understand that in specific implementation, the control host 10 can be configured with an AC-DC conversion circuit to convert alternating current to direct current, and can be configured with a DC voltage conversion circuit to convert the voltage of alternating current. Of course, the control host 10 can also be configured with multiple voltage conversion units to convert the voltage of direct current, and then output direct current with different voltage values as working power for use by various units.

[0077] Based on the above example, based on the first direct current voltage output by the first power supply branch, a DC-DC voltage conversion circuit can be configured in the handheld assembly 100 to output a third direct current voltage based on the first direct current voltage as the power supply voltage for specific components in the circuit, such as a direct current voltage with a voltage value in the range of 5-3.3V.

[0078] It is understandable that since AC / DC conversion and DC voltage transformation can both be achieved using existing conversion or transformation circuits, they will not be elaborated upon here.

[0079] In this embodiment, the control host is used to convert the electrical energy provided by the power supply, which can make the beauty device compatible with different power supply systems and broaden the applicability of the beauty device.

[0080] Understandably, in practical implementation, the beauty device can also be equipped with an independent power source, such as a rechargeable battery. Here, by connecting the control unit to the handheld component, the power supplied by the main unit can also be used to charge the rechargeable battery in the handheld component.

[0081] It is easy to understand that, in actual implementation, the beauty device 300 can also be configured with a control unit to determine that the handheld component has been installed with the beauty head based on the in-situ electrical signal.

[0082] Of course, in other embodiments, the control unit can also be used to control the operation of the beauty device when the beauty head is mounted on the handheld component. That is, to control the beauty device to output corresponding physical energy, such as light energy, electrical energy, or heat energy, through the beauty head to act on the skin.

[0083] For example, a control unit (not shown in the figure) can be configured in the control host 10.

[0084] For example, a control unit (not shown in the figure) can be configured in the handheld component 100.

[0085] Figure 5 A schematic diagram of the specific structure of a beauty device according to another embodiment of this application is shown. As an embodiment, in... Figure 5 In this assembly, the beauty head 200 is also configured with a third contact point 215 and an information encryption unit 240. The information encryption unit 240 is connected to the third contact point 215. The handheld component 100 is configured with a fourth contact point 115 and a control unit 140. The control unit 140 is connected to the fourth contact point 115. Here, when the beauty head 200 is mounted on the handheld component 100, the information encryption unit 240 and the control unit 140 are connected via the third contact point 215 and the fourth contact point 115. Accordingly, the control unit 140 is also used to obtain encrypted information from the information encryption unit 240 to determine the attribute information of the beauty head 200 based on the encrypted information.

[0086] In the embodiment, the encryption unit 240 can carry or store the attribute information of the cosmetic head 200. When the cosmetic head 200 is mounted on the handheld assembly 100, the third connection contact 215 contacts the fourth connection contact 115, and the path between the encryption unit 240 and the control unit 140 is conducted. At this time, the control unit 140 can access the encryption unit 240 through the path, and further obtain the encryption information, and determine the attribute information of the cosmetic head 200 according to the encryption information.

[0087] In a specific implementation, the encryption unit 240 can be a storage circuit configured with a memory in which the encryption information is stored. The control unit 140 can access the memory to obtain the encryption information.

[0088] In the embodiment, the encryption unit stores the encryption information, and when the handheld assembly is mounted with the cosmetic head, the control unit can access the encryption unit to obtain the encryption information and determine the attribute information of the cosmetic head according to the encryption information. In this way, not only can the control unit automatically identify the type of the cosmetic head when the handheld assembly is mounted with the cosmetic head, but also can provide a basis for improving the intelligent degree of the cosmetic instrument.

[0089] As an embodiment, the control host 10 and / or the handheld assembly 100 are configured with a display module (not shown in the figure). The control unit 140 is further configured to control the display module to display the attribute information.

[0090] In a specific implementation, the display module can be a display screen. When the control unit 140 obtains the attribute information, the function or type of the cosmetic head 200 can be determined, and the attribute information can be displayed through the display module, so that the user can know the attribute of the cosmetic head by observing the display module.

[0091] Here, the attribute information can specifically include specification information and / or use data for distinguishing the cosmetic head 200. For example, the attribute information can include the type or specification of the cosmetic head 200.

[0092] Taking the cosmetic head 200 as an ultrasonic gun cosmetic head as an example, the specification information in the attribute information can specifically include the barrel diameter and / or energy acting area of the ultrasonic gun. The use data can include the remaining use times and / or the used times, and / or the time of the last use, and / or the time of each use, etc. which are not limited here.

[0093] As a possible implementation, the cosmetic head 200 can be distinguished according to different functions or output different energy. For example, the cosmetic head 200 is configured with a first cosmetic head (not shown in the figure), which is configured with an ultrasonic transducer. Here, the ultrasonic transducer is used to output ultrasonic energy. That is, when the first cosmetic head is installed on the handheld assembly 100, the ultrasonic energy can be output through the first cosmetic head to act on the skin.

[0094] For another example, the cosmetic head 200 is also configured with a second cosmetic head (not shown in the figure), which is configured with a light-transmitting part and a light-emitting unit. The light-transmitting part is used for light transmission, and the light-emitting unit is used for generating light through the light-transmitting part. Here, the light-emitting unit is used to output light energy. That is, when the second cosmetic head is installed on the handheld assembly 100, the light energy can be output through the second cosmetic head to act on the skin. The light-emitting unit can be configured with a light source, which is used to output at least one of pulsed light, near-infrared light, blue light, red light, and yellow light.

[0095] In specific implementation, different light sources can be configured according to different light energy output by the light-emitting unit. For example, the light source corresponding to the pulsed light can be a pulsed light tube filled with inert gas. The light source corresponding to the near-infrared light can be a halogen tungsten lamp. The light sources corresponding to the blue light, the red light, and the yellow light can be LED lamps.

[0096] It is easy to understand that in specific implementation, the second cosmetic head can be provided with at least two light sources. For example, the second cosmetic head can be configured with a pulsed light tube and an LED lamp, and after the pulsed light is triggered, the LED lamp can be used to soothe the skin.

[0097] For another example, the second cosmetic head can be configured with a halogen tungsten lamp and an LED lamp, and after the near-infrared light is triggered to irradiate the skin, the LED lamp can be used to soothe the skin.

[0098] In some embodiments, the second cosmetic head can also be configured with a refrigeration unit (not shown in the figure). Here, the refrigeration unit is in contact with the light-transmitting part and is used to output cold energy to the light-transmitting part. Here, since the refrigeration unit can output cold energy to the light-transmitting part, when the light energy is output to the skin through the second cosmetic head, the light-transmitting part can be prevented from causing a burning sensation of the skin due to excessive temperature. Or, after the light energy is output to the skin using the second cosmetic head, the LED lamp can be used in combination with the refrigeration unit to soothe the skin through light irradiation and cold compression.

[0099] In this embodiment, by providing cosmetic heads with different functions, not only can the functions of the cosmetic instrument be enriched, but also the sustainable use of the cosmetic instrument can be realized by replacing the cosmetic heads. This helps to improve the user's stickiness to the cosmetic instrument.

[0100] Figure 6A schematic diagram of the overall scheme of a beauty instrument is shown. As shown in Figure 6 The beauty instrument 300 is configured with a handheld assembly 100 and a beauty head 200. The handheld assembly 100 and the beauty head 200 are detachably connected.

[0101] For example, in combination Figures 1 to 5 The beauty head 200 is configured with a first connection contact 210 and a first sensing element 220. The first connection contact 210 and the first sensing element 220 are connected through internal wiring of the beauty head 200.

[0102] In this embodiment, the second sensing element 230 is arranged apart from the first sensing element 220. In a specific implementation, the first sensing element 220 and the second sensing element 230 can be arranged apart on an active surface of the beauty head 200. For example, the beauty head 200 is configured with an active surface for outputting energy to act on the skin. The first sensing element 220 and the second sensing element 230 can be arranged around the active surface.

[0103] As shown in Figure 6 The active surface 201 of the beauty head 200 is rectangular, and accordingly, the first sensing element 220 and the second sensing element 230 can be arranged around the active surface 201. In the example shown in Figure 6 The first sensing element 220 is arranged around one side length of the active surface 201 in the width direction, and the other three second sensing elements 230 are arranged apart around the other three side lengths of the active surface 201.

[0104] In a specific implementation, the first sensing element 220 can also be arranged in the length direction of the active surface 201, and the second sensing element 230 can be arranged apart from the first sensing element 220 in the length direction and / or the width direction of the active surface 201.

[0105] It is easy to understand that, similar to the first sensing element 220, the second sensing element 230 can also be connected to the first connection contact 210 through internal wiring of the beauty head 200. In this way, the capacitive touch detection circuit in the handheld assembly 100 can cooperate with the first sensing element 220 and the second sensing element 230 to identify whether the beauty head 200 is attached to the skin.

[0106] In combination Figures 1 to 6 The handheld assembly 100 is configured with a receiving groove 101 matched with the shape of the beauty head 200, for mounting the beauty head 200. Specifically, as shown in Figure 6 The second connection contact 110 is arranged at the bottom of the receiving groove 101. Here, the second connection contact 110 can be embedded in the handheld assembly 100. In this way, when the beauty head 200 is mounted on the handheld assembly 100, the first connection contact 210 (Figure 6 (Not shown) makes contact with the second contact point 110, thereby opening the path between the capacitive touch detection circuit 120 and the first sensor 220. When the path between the capacitive touch detection circuit 120 and the first sensor 220 is open, it generates an in-situ electrical signal, which is used to determine that the beauty head 200 has been installed on the handheld component 100.

[0107] Figure 7 A schematic diagram of a circuit board for a beauty device according to an embodiment of this application is shown. Figure 7 As shown, in one embodiment, the handheld component 100 includes handheld circuitry, and the beauty head 200 includes a head circuit board. (As illustrated...) Figure 7 As shown, the first contact point 210 is a pin point provided on the head circuit board of the beauty head 200, and the second contact point 110 is formed by a pin needle provided on the handheld circuit board of the handheld assembly 100.

[0108] It is readily understood that, in some embodiments, the third contact point in the beauty head 200 may also be the same pin as the first contact point 210. Correspondingly, the fourth contact point in the handheld assembly 100 may also be formed with the same pin as the second contact point 110.

[0109] Combination Figure 6 and Figure 7 In practical implementation, each unit in the beauty head 200, such as the first sensor 220, the second sensor 230, and the encryption unit 240, can be configured in the head circuit board. Similarly, each unit in the handheld assembly 100, such as the capacitive touch detection circuit 120, and / or the prompting unit 130, and / or the control unit 140, can be configured in the handheld circuit board.

They do not constitute a limitation or restriction on the specific shape and structure of the beauty device provided in this application's embodiments.
