Description

Technical Field

[0001] This utility model relates to the field of skin treatment, and in particular to a skin treatment device, an accessory head, and a skin treatment apparatus. Background Technology

[0002] Skin treatment devices can perform at least one of the following treatments: whitening, freckle removal, skin rejuvenation, or hair removal. These devices have high output power; therefore, to prevent accidental activation and potential damage to other parts of the user's body (such as the eyes), sensors are needed to ensure proper contact between the device and the skin. The device should only be activated when in good contact. To broaden the application scenarios of the skin treatment device, an accessory head can be installed. After the accessory head is installed on the main unit, an additional Hall sensor is required to prevent it from being mistaken for skin. However, using a Hall sensor to identify the accessory head is costly in related technologies. Utility Model Content

[0093] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0094] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0095] Skin treatment devices can perform at least one of the following treatments: whitening, freckle removal, skin rejuvenation, or hair removal. Taking a hair removal device as an example, the device uses a light-emitting component to emit light that shines onto the skin, thus removing hair. Because the light has high output power, to prevent accidental activation and potential damage to other parts of the user's body (such as the eyes), a sensor is needed to ensure the light-emitting end of the device is in good contact with the skin. The device should only be turned on when there is good contact and minimal light leakage, thus reducing the chance of accidental activation and potential damage to other parts of the user's body.

[0096] For different usage scenarios, the light emission area or light parameters of a hair removal device may vary. Therefore, hair removal devices can be equipped with an accessory head. This accessory head, installed on the main unit, can alter the light emission area or light parameters. For example, the size of the opening in the accessory head for emitting high-energy light can limit the light emission area, and the specific parameters of the filter within that opening can change the light parameters. To prevent the skin recognition sensor from misidentifying the accessory head as skin, related technologies incorporate an additional Hall sensor on the main unit to identify the presence and / or type of the accessory head. The addition of a Hall sensor increases the overall cost of the hair removal device.

[0097] In view of this, see Figures 1-21Some embodiments of this application provide a skin treatment device 10, which can reduce the material cost of skin treatment apparatus 1 in related technologies. The skin treatment device 10 of this application can perform any form of treatment on the skin to be treated. For example, the skin treatment device 10 can perform at least one of the following treatments: whitening, freckle removal, skin rejuvenation, hair removal, or massage. Exemplarily, the skin treatment device 10 can be a whitening instrument, freckle removal instrument, skin rejuvenation instrument, hair removal instrument, massage instrument, or radiofrequency beauty instrument, etc., used for skin treatment.

[0098] The skin treatment device 10 is adapted to connect at least one auxiliary head 20, the specific structure of which varies depending on the specific type of the skin treatment device 10. A skin treatment device 10 may be paired with only one auxiliary head 20 or with multiple auxiliary heads 20 simultaneously. One or more auxiliary heads 20 together with the skin treatment device 10 constitute the skin treatment apparatus 1. In other words, the skin treatment apparatus 1 includes the skin treatment device 10 and at least one auxiliary head 20. The skin treatment device 10 can treat the skin to be treated individually, or it can be detachably connected to one of the auxiliary heads 20 to treat the skin. In some embodiments, the skin treatment device 10 can also be detachably connected to multiple auxiliary heads 20 to treat the skin; in other embodiments, the skin treatment device 10 may not be convenient to treat the skin alone and requires connection to at least one auxiliary head 20 to treat the skin.

[0099] See Figures 1-10 The skin treatment device 10 includes a housing 100, a skin treatment component 200, a first sensor 300, a second sensor 400, and a capacitive touch recognition circuit 800.

[0100] See Figures 1-3 The housing 100 has a function output section 110 that outputs energy for skin treatment. The type and intensity of the energy output by the function output section 110 vary depending on the type of skin treatment device 10. For example, in some embodiments, when the skin treatment device 10 is a hair removal device, see [link to relevant documentation]. Figure 1 The function output section 110 of the outer casing 100 can be a head shell 111 portion having a light outlet 1131. The outer casing 100 defines a receiving cavity 120, and the light outlet 1131 of the head shell 111 communicates with the receiving cavity 120. During the use of the hair removal device, the user holds the outer casing 100, bringing the function output section 110 close to or against the skin to be treated, and allowing the treatment light to pass through the light outlet 1131 to irradiate the skin to be treated, thereby performing hair removal treatment on the skin.

[0101] A skin treatment unit 200 is located in the function output section 110. The skin treatment unit 200 generates energy to act on the skin to be treated. Different energy output methods of the skin treatment unit 200 correspond to different types of skin treatment devices 10. For example, see... Figures 1-10 In some embodiments, when the skin treatment device 10 is a hair removal device, the skin treatment component 200 may include a light-emitting component 240 that generates intense pulsed light or laser. The heat energy generated by the intense pulsed light or laser can destroy hair follicles and surrounding stem cells, thereby preventing hair regrowth and achieving the purpose of hair removal. In some embodiments, when the skin treatment device 10 is a skin rejuvenation device, the skin treatment component 200 may be a set of LED lights that emit light of specific wavelengths to promote skin cell activity and collagen production. In some embodiments, when the skin treatment device 10 is a massage device, the skin treatment component 200 may also include a heating element that massages the skin by transferring heat to it, thereby relieving user fatigue.

[0102] See Figures 2-4 A first sensor 300 is disposed on the function output section 110. The first sensor 300 is used to sense the skin to determine whether the function output section 110 is in contact with the skin to be treated. When the skin treatment device 10 needs to start working, after the function output section 110 is in contact with the skin to be treated, the first sensor 300 connected to the function output section 110 can sense the skin. Specifically, the first sensor 300 may include a first sensing terminal and a first sensing circuit electrically connected to each other. When the first sensing terminal of the first sensor 300 is close to the skin, the capacitance changes, thereby generating a change in the electrical signal of the first sensing circuit, that is, the first sensor 300 generates a first sensing signal. The capacitive touch recognition circuit 800, which is electrically connected to the first sensor 300, processes the first sensing signal and generates a first control signal. The MCU of the skin treatment device 10 enables the skin treatment device 10 based on the first control signal. That is, at this time, the skin treatment device 10 is in a state that can be turned on, and the user controls the light-emitting component 240 to turn on and off through a switch signal. Since the function output section 110 is in contact with the skin at this time, the energy output by the skin treatment device 200 is unlikely to cause harm to other parts of the user's body. When the skin treatment device 10 does not need to work, since the function output section 110 is away from the skin, the first sensor 300 connected to the function output section 110 cannot sense the skin (i.e., the first sensing end of the first sensor 300 cannot sense any change in capacitance). As a result, the MCU of the skin treatment device 10 cannot obtain the second control signal, and the skin treatment device 10 remains in an disabled state, that is, the skin treatment device 10 is in a state that cannot be turned on. At this time, even if the user tries to send a switch signal to the skin treatment device 10, the device will not respond, thereby ensuring the safety of use.

[0103] See Figures 2-4 The second sensor 400 is disposed on the function output section 110, and is spaced apart from the first sensor 300, with each sensor located at a different position on the function output section 110. A third sensor 22 is provided on the auxiliary head 20. The second sensor 400 senses the third sensor 22 on the auxiliary head 20, but does not sense the skin when the function output section 110 is in contact with the skin to be treated. When the auxiliary head 20 is provided on the skin treatment device 10, after the auxiliary head 20 is installed on the skin treatment device 10, the third sensor 22 corresponds to the position of the second sensor 400, at which point the second sensor 400 senses the third sensor 22. Specifically, the second sensing element 400 may include a second sensing terminal and a second sensing circuit electrically connected to each other. When the second sensing terminal of the second sensing element 400 approaches the third sensing element 22, the capacitance changes, thereby causing the second sensing circuit to generate a change in electrical signal, that is, the second sensing element 400 generates a second sensing signal. The capacitive touch recognition circuit 800, which is electrically connected to the second sensing element 400, processes the second sensing signal and generates a second control signal. Based on the second control signal, the MCU of the skin treatment device 10 determines that the skin treatment device 10 is connected to the auxiliary head 20. At this moment, the MCU of the skin treatment device 10 still keeps the skin treatment device 10 in a disabled state when it receives the first control signal, thereby effectively reducing the possibility that the skin treatment device 10 misidentifies the auxiliary head 20 as skin. When the auxiliary head 20 is not installed on the skin treatment device 10, during operation, the function output unit 110 is in contact with the skin, and after the first sensor 300 senses the skin, the second sensor 400 is at a relatively far distance from the skin. Therefore, the second sensor 400 cannot sense the skin or the third sensor 22 of the auxiliary head 20. Consequently, the MCU of the skin treatment device 10 cannot obtain the second control signal, thus determining that the skin treatment device 10 is not connected to the auxiliary head 20. Through this design, the skin treatment device 10 can accurately identify the presence or absence of the auxiliary head 20 when treating the skin, avoiding misoperation.

[0104] During the aforementioned sensing process, both the first sensor 300 and the second sensor 400 generate electrical signals through changes in capacitance. The capacitive touch recognition circuit 800 processes these generated electrical signals and generates corresponding control signals. Based on these control signals, the MCU of the skin treatment device 10 controls the operating state of the skin treatment device 10, ensuring effective skin sensing when the auxiliary head 20 is not present, preventing misoperation, and improving safety. In this embodiment, both the first sensor 300 and the second sensor 400 are electrically connected to the capacitive touch recognition circuit 800. Compared to related technologies where the first sensor 300 is a capacitive sensor and the second sensor 400 is a Hall sensor, the two sensors in this solution use the same sensing method, which is more conducive to mass production. Furthermore, the cost of the second sensor 400 is lower than the material cost of the Hall sensor, thereby reducing the overall material cost of the skin treatment device 10. In addition, the high sensitivity of the capacitive touch recognition circuit 800 ensures the accuracy of the sensing signal, further improving the device's working efficiency and user experience. Moreover, the sensing of capacitive sensors does not depend on changes in the magnetic field, which eliminates the need for magnetic components on the auxiliary head 20, and also reduces the processing and material costs of the auxiliary head 20.

[0105] The specific type of skin treatment device 10 depends on actual needs. For ease of description, unless otherwise specified, the following description will primarily use a hair removal device as an example. For details, please refer to... Figures 2-4 When the skin treatment device 10 is a hair removal device, in some embodiments, the skin treatment component 200 may include a light-emitting component 240. The light-emitting component 240 is disposed within the housing 100 and connected to the functional output unit 110. The light-emitting component 240 may include a light-emitting element 241, which may be an LED or a laser diode, etc. The light-emitting element 241 is used to generate high-energy light that irradiates the skin surface. The functional output unit 110 has a light outlet 1131. The high-energy light beam is led out through the light outlet 1131 of the functional output unit 110 and irradiates the skin to be treated. The high-energy light can destroy hair follicles and surrounding stem cells, thereby preventing hair regrowth and achieving the purpose of hair removal. The first sensor 300 and the second sensor 400 can be disposed at any convenient sensing position in the functional output unit 110. Specifically, in this embodiment, the first sensor 300 and the second sensor 400 are disposed around the light outlet 1131. This ensures sensing accuracy while effectively avoiding the light outlet 1131. Furthermore, compared to other types of devices, the skin treatment device 10 has a higher energy output and is relatively more dangerous. Therefore, a precise sensing mechanism is particularly important. Thus, adopting this solution to sense the accessory head 20 can further enhance the safety protection value of the skin treatment device 10.

[0106] To facilitate the output of light generated by the light-emitting element 241 through the light port 1131, see [link to relevant documentation]. Figures 2-4 In some embodiments, the light-emitting component 240 may further include a light guide 242. The light guide 242 is disposed within the housing 100 and connected to the functional output section 110. The light guide 242 covers the light outlet 1131 and is used to guide the light generated by the light-emitting element 241 out of the housing 100 through the light outlet 1131. The light guide 242 covering the light outlet 1131 makes it difficult for external foreign objects to enter the housing 100 through the light outlet 1131, thus improving the sealing effect of the housing 100. The light generated by the light-emitting element 241 enters the light guide 242 from one end, is conducted through the light guide 242, and finally exits the housing 100 from the other end of the light guide 242. The light guide 242 can be made of a material with high light transmittance and high heat resistance. The high light transmittance of the light guide 242 results in low energy loss after the treatment light is conducted through it; the heat resistance of the light guide 242 prevents it from deforming or being damaged after absorbing the energy of the treatment light and heating up. Furthermore, the light guide 242 can be directly applied to the skin to be treated to achieve a cooling effect. Therefore, the light guide 242 can also be made of a highly heat-insulating material. For example, the material of the light guide 242 can be sapphire or quartz. Of course, in other embodiments, the light-emitting component 240 may not include the light guide 242, and the light generated by the light-emitting element 241 can be directly discharged from the light outlet 1131.

[0107] The specific structure and relative arrangement of the first sensor 300 and the second sensor 400 can be determined according to actual needs, as long as they can perform their corresponding sensing functions. For details, see [link to documentation]. Figures 2-4 In some embodiments, the first sensor 300 may be annular, and an annular first sensor 300 has a larger sensing area, thus providing more accurate skin sensing. Further, observation along the centerline direction Z of the light outlet 1131 (i.e., along...) Figure 4 (As shown in the diagram), the annular first sensor 300 can be arranged around the light outlet 1131. In this design, the first sensor 300 can sense skin at any position around the light outlet 1131, effectively reducing the probability that the first sensor 300 will not sense skin under certain placement angles during normal operation of the hair removal device, thus preventing the device from turning on properly. In some embodiments, when the first sensor 300 is annular, the second sensor 400 can be located outside the first induction coil, so that the sensing area of ​​the second sensor 400 does not overlap with the sensing area of ​​the first sensor 300. The sensing processes of the first sensor 300 and the second sensor 400 will not interfere with each other, improving the sensing accuracy of the first sensor 300 and the second sensor 400, and ensuring the independence and accuracy of the sensing data.

[0108] See Figures 2-4 In some embodiments, along the centerline direction Z of the light outlet 1131, the second sensor 400 may be located on the side of the first sensor 300 opposite to the light outlet 1131. In other words, when the skin treatment device 10 is working normally and the function output section 110 is in contact with the planar skin, the distance between the first sensor 300 and the skin is relatively closer, thus the first sensor 300 has higher sensing accuracy for the skin; the distance between the first sensor 300 and the skin is relatively farther, thus making it less likely for the second sensor 400 to sense the skin, thereby reducing the probability that the second sensor 400 mistakenly senses the skin as the accessory head 20.

[0109] See Figures 2-4 In some embodiments, the functional output unit 110 includes a head shell 111, which is adapted to fit against the skin and to be detachably connected to the accessory head 20. The head shell 111 includes an end plate 113 located on the inner side and an outer peripheral plate 114 located on the outer periphery of the end plate 113. The outer periphery of the end plate 113 is connected to the inner periphery of the outer peripheral plate 114. The end plate 113 and the outer peripheral plate 114 can be assembled or integrally molded. In this embodiment, the end plate 113 and the outer peripheral plate 114 are integrally injection molded. The end plate 113 is provided with the light outlet 1131 described above. The high-energy light generated by the light-emitting component 240 is led out of the outer shell 100 through the light outlet 1131 of the end plate 113. When the accessory head 20 fits against the skin, the opening area of ​​the outer peripheral plate 114 gradually increases in the direction gradually away from the skin (i.e., the outer peripheral plate 114 is flared). The flared outer peripheral plate 114 is more convenient for assembly and connection with the accessory head 20.

[0110] The first sensor 300 can be attached to any suitable location on the head shell 111. In some embodiments, the first sensor 300 is attached to the end plate 113, thereby allowing the first sensor 300 to be closer to the skin and improving sensing sensitivity. See specifically... Figures 3-4 as well as Figure 6In some embodiments, the first sensing element 300 can be connected to the inner side of the end plate 113, that is, the first sensing element 300 can fit against the side of the end plate 113 facing the receiving cavity 120 of the outer shell 100. This arrangement makes the placement of the first sensing element 300 more convenient. In other embodiments, the first sensing element 300 can be disposed inside the end plate 113. In this arrangement, when the end plate 113 is injection molded (or when the outer peripheral plate 114 and the end plate 113 are integrally injection molded), the first sensing element 300 can be directly placed in the injection mold of the end plate 113, so that the end plate 113 and the first sensing element 300 are integrally injection molded. Alternatively, the end plate 113 can be formed by splicing two plates, and the first sensing element 300 is clamped between the two plates, thereby realizing the structure in which the first sensing element 300 is located inside the end plate 113. The structure of the first sensor 300 located within the end plate 113 makes it less prone to damage, extending its service life. Simultaneously, it allows the first sensor 300 to be positioned closer to the outer side of the end plate 113, enabling it to be closer to the skin when the function output section 110 is in contact with the skin, resulting in more accurate sensing. (See also...) Figure 5 In some embodiments, the end plate 113 may have a first groove 1132 facing the inner wall of the receiving cavity 120, and the first sensor 300 is embedded in the first groove 1132. This facilitates the placement of the first sensor 300 within the end plate 113 and reduces the distance between the first sensor 300 and the skin. In other embodiments, the first sensor 300 may also be located on the outer surface of the end plate 113, thereby further improving sensing accuracy.

[0111] The second sensor 400 can also be connected to any suitable position on the head shell 111, see [link / reference]. Figures 3-4 as well as Figure 6 In some embodiments, the second sensor 400 may be connected to the outer peripheral plate 114 of the head shell 111. In this configuration, the second sensor 400 can bypass the end plate 113, which is primarily used for skin contact, thereby allowing it to be located further away from the skin during the operation of the skin treatment device 10. Furthermore, because the outer peripheral plate 114 is flared, the distance between the second sensor 400 and the skin can be further increased, reducing the probability of false detection by the second sensor 400. Further, see... Figures 3-4 as well as Figure 6In some embodiments, the second sensing element 400 can be connected to the inner side of the outer peripheral plate 114, that is, the second sensing element 400 can fit against the side of the outer peripheral plate 114 facing the receiving cavity 120 of the outer shell 100. This arrangement makes the placement of the second sensing element 400 more convenient. In other embodiments, the second sensing element 400 can be disposed within the outer peripheral plate 114. In this arrangement, when the outer peripheral plate 114 is injection molded (or when the outer peripheral plate 114 and the end plate 113 are integrally injection molded), the first sensing element 300 can be directly placed in the injection mold of the outer peripheral plate 114, so that the outer peripheral plate 114 and the second sensing element 400 are integrally injection molded. Alternatively, the outer peripheral plate 114 can be formed by splicing two plates, and the second sensing element 400 is clamped between the two plates, thereby realizing the structure in which the second sensing element 400 is located inside the outer peripheral plate 114. See also Figure 5 In some embodiments, the outer peripheral plate 114 has a second groove 1143 facing the inner wall of the receiving cavity 120, and the second sensor 400 is embedded in the second groove 1143. This facilitates the arrangement of the second sensor 400 within the outer peripheral plate 114. The structure of the second sensor 400 within the outer peripheral plate 114 makes the second sensor 400 less prone to damage, extending its service life. Simultaneously, it allows the second sensor 400 to be closer to the outer side of the outer peripheral plate 114, reducing the distance between the second sensor 400 and the auxiliary head 20, thus making the sensing of the auxiliary head 20 more accurate. In other embodiments, the second sensor 400 can also be located on the outer surface of the outer peripheral plate 114, further improving sensing accuracy. In some embodiments, the second sensor 400 may also be located at one end of the outer peripheral plate 114 away from the end plate 113. Since the outer peripheral plate 114 is flared, the second sensor 400 may be arranged at a position further away from the center of the end plate 113, that is, further away from the skin, which further reduces the risk of false recognition by the second sensor 400.

[0112] See Figures 4-5In some embodiments, the function output section 110 has a width direction Y and a thickness direction X, and the width of the function output section 110 is greater than its thickness. The outer peripheral plate 114 includes two first side plates 1141 located in the width direction Y of the function output section 110 and two second side plates 1142 located in the width direction Y of the function output section 110. The two first side plates 1141 and the two second side plates 1142 are alternately connected end to end along the circumference of the light outlet 1131. In particular, in this embodiment, the angle between the first side plate 1141 and the end plate 113 is greater than the angle between the second side plate 1142 and the end plate 113. Simultaneously, when the outer wall of the end plate 113 is in contact with the skin, the distance between the two first side plates 1141 gradually increases along the direction away from the skin from the end plate 113, and the distance between the two second side plates 1142 gradually increases, with the rate of increase of the distance between the two first side plates 1141 being greater than the rate of increase of the distance between the two second side plates 1142. In this embodiment, the second sensor 400 is disposed on the first side plate 1141. In this design, the arrangement space for the second sensor 400 is larger, and the second sensor 400 can be arranged further away from the center of the end plate 113, i.e., further away from the skin, further reducing the risk of false recognition by the second sensor 400.

[0113] See Figure 7 In some embodiments, the function output unit 110 includes a head shell 111, which is adapted to conform to the skin and to be detachably connected to the accessory head 20. Specifically, the head shell 111 includes a recess 115, which forms a third groove 1151 with an opening facing outwards from the head shell 111 (i.e., the recess 115 is recessed inwards towards the outer shell 100), and a second sensor 400 is connected to the recess 115. Specifically, the recess 115 may include a bottom wall plate 1152 facing the opening of the third groove 1151 and a peripheral wall plate 1153 surrounding the opening. The second sensor 400 may be disposed on the bottom wall plate 1152, specifically on the outer wall of the bottom wall plate 1152 facing the opening, on the inner wall of the bottom wall plate 1152 away from the opening, or inside the bottom wall plate 1152. When the second sensor 400 is disposed on the bottom wall plate 1152 of the groove, it can be further away from the skin, reducing the probability of misidentifying the skin as the accessory head 20. In other embodiments, the second sensor 400 can also be disposed on the peripheral wall plate 1153 of the groove, specifically on the inner peripheral wall surface of the peripheral wall plate 1153 facing the third groove 1151, or on the outer peripheral wall surface of the peripheral wall plate 1153 facing away from the third groove 1151.

[0114] When the head shell 111 has a recess 115 and the second sensing element 400 is disposed in the recess 115, see Figure 7 as well as Figure 20In some embodiments, the auxiliary head 20 may include a protrusion 213 on the side facing the skin treatment device 10, the protrusion 213 extending into the third recess 1151, and the third sensor 22 connected to the protrusion 213. The third sensor 22 may be located at a position corresponding to the second sensor 400. For example, when the second sensor 400 is located on the bottom wall plate 1152 of the tank, the third sensor 22 may be located at the end position where the protrusion 213 abuts against or is spaced from the bottom wall plate 1152. When the second sensor 400 is located on the peripheral wall plate 1153 of the tank, the third sensor 22 may be located at the side wall position where the protrusion 213 abuts against or is spaced from the peripheral wall plate 1153. In this embodiment, the cooperation between the protrusion 213 and the recess 115 allows the third sensor 22 to be closer to the second sensor 400, thereby making it easier for the second sensor 400 to sense the third sensor 22 and improving the sensing accuracy. In a further embodiment, the protrusion 213, besides serving to house the third sensor 22 for sensing the second sensor 400 within the recess 115, can also be used to connect to the head shell 111. Specifically, a first connecting structure can be provided on the protrusion 213, and a second connecting structure can be provided within the recess 115. The first connecting structure and the second connecting structure can be engaged, interference-fitted, or magnetically connected, etc., so that the auxiliary head 20 can achieve a detachable connection with the head shell 111. Of course, in other embodiments, the protrusion 213 and the recess 115 can also be used solely for the connection between the auxiliary head 20 and the head shell 111, with the second sensor 400 and the third sensor 22 located at other positions outside the protrusion 213 and the recess 115, which will not be elaborated here.

[0115] In addition to being connected to the head shell 111 of the function output section 110, the first sensor 300 and the second sensor 400 can also be disposed at other locations in the function output section 110. Specifically, see Figure 8In some embodiments, the function output unit 110 includes a head shell 111, which is adapted to conform to the skin and to be detachably connected to the accessory head 20. The head shell 111 includes an inner end plate 113 and an outer peripheral plate 114 located on the outer periphery of the end plate 113, the outer peripheral plate 114 being flared. The end plate 113 is provided with a light outlet 1131. The skin treatment device 10 also includes a light guide 242, which is located at the light outlet 1131. The function output unit 110 also includes a bracket 112, which is used to fix the light guide 242. The bracket 112 is located on the side of the head shell 111 facing the receiving cavity 120 and is spaced apart from or abuts against the head shell 111. The first sensor 300 is disposed on the bracket 112, specifically connected to the end of the bracket 112 near the end plate 113. In this design, the first sensor 300 can be connected to the surface of the bracket 112 or disposed inside the bracket 112. The structure of the first sensor 300 being connected to the bracket 112 facilitates the overall assembly of the skin treatment device 10, and the assembly of the first sensor 300 is not limited by the position of the head shell 111. Furthermore, in this embodiment, the second sensor 400 can be connected to the inner side of the outer peripheral plate 114 or disposed inside the outer peripheral plate 114.

[0116] In some embodiments, the first sensor 300 and the second sensor 400 are oriented differently, resulting in different sensing directions. Specifically, the first sensor 300 may be more sensitive to sensing along the centerline direction Z of the light outlet 1131, while the second sensor 400 may be more sensitive to sensing in other directions intersecting the centerline direction Z. In this configuration, when the first sensor 300 senses skin, the second sensor 400 is oriented away from the skin, thus being less sensitive to skin and reducing the likelihood of the second sensor 400 misidentifying skin as the accessory head 20.

[0117] See Figures 4-8 ,as well as Figures 15-18In some embodiments, the skin treatment device 10 includes a plurality of second sensors 400, each of which is electrically connected to a capacitive touch recognition circuit 800. Each second sensor 400 is configured to sense at least one accessory head 20 to identify the type of accessory head 20 based on the number and / or position of the accessory head 20. For example, the skin treatment device 1 may have four second sensors 400 located at different positions; for example, the four second sensors 400 may be correspondingly located around the light guide 242. Correspondingly, one skin treatment device 10 may be matched with four accessory heads 20, each of which has at least one third sensor 22, and the third sensors 22 of the four accessory heads 20 are located at different positions; for example, the accessory head 20 has a light-transmitting opening 211, and the third sensor 22 of the first accessory head 20 is located at the light-transmitting opening 211. Figure 17 Above the light-transmitting opening 211 indicating orientation, the third sensor 22 of the second auxiliary head 20 is disposed on the auxiliary head 20. Figure 18 Below the light-transmitting opening 211 indicating orientation, the third sensor 22 of the third auxiliary head 20 is located on the auxiliary head 20. Figure 15 The third sensor 22 of the fourth auxiliary head 20 is located to the left of the light-transmitting opening 211 indicating orientation. Figure 16 To the right of the light-transmitting opening 211 indicating orientation. Four third sensors 22 correspond one-to-one with four second sensors 400. When the accessory head 20 is installed on the skin treatment device 10, the corresponding second sensor 400 senses the corresponding third sensor 22 on the accessory head 20. Therefore, the type of accessory head 20 can be determined by the position information of the corresponding second sensor 400. In other embodiments, different accessory heads 20 may have different numbers of third sensors 22. After different accessory heads 20 are installed on the skin treatment device 10, the number of second sensors 400 sensed by the skin treatment device 10 and the accessory head 20 will differ. By confirming the number of second sensors 400 sensed by the accessory head 20, the type of accessory head 20 can be determined.

[0118] See Figure 9In some embodiments, the skin treatment device 10 further includes a first circuit board 500, a second circuit board 600, and a third circuit board 700. The first circuit board 500 is equipped with a capacitive touch recognition circuit 800. The first circuit board 500 may contain an MCU, or the first circuit board 500 may be electrically connected to another circuit board containing an MCU. A first sensor 300 is electrically connected to the first circuit board 500 via the second circuit board 600, thereby connecting the first sensor 300 to the capacitive touch recognition circuit 800. A second sensor 400 is electrically connected to the first circuit board 500 via the third circuit board 700, thereby connecting the second sensor 400 to the capacitive touch recognition circuit 800. The second circuit board 600 and the third circuit board 700 are flexible circuit boards. In this design, because the second circuit board 600 and the third circuit board 700 can undergo small-range deformation, it is easier to arrange the positions of the first sensor 300 and the second sensor 400, reducing the assembly accuracy requirements of the first sensor 300 and the second sensor 400. In other embodiments, the first circuit board 500, the second circuit board 600, and the third circuit board 700 may all be flexible circuit boards.

[0119] See Figure 10 In some embodiments, the skin treatment device 10 further includes a first circuit board 500 and a second circuit board 600 electrically connected to each other. The first circuit board 500 is provided with a capacitive touch recognition circuit 800. The first circuit board 500 may be provided with an MCU, or the first circuit board 500 may be electrically connected to other circuit boards provided with an MCU. The first sensor 300 and the second sensor 400 are both electrically connected to the second circuit board 600. The second circuit board 600 includes a trunk board 610, a first branch board 620, and a second branch board 630. The trunk board 610 is electrically connected to the first circuit board 500. One end of the first branch board 620 is electrically connected to the trunk board 610 and the other end is electrically connected to the first sensor 300. One end of the second branch board 630 is electrically connected to the trunk board 610 and the other end is electrically connected to the second sensor 400. The second circuit board 600 is a flexible circuit board. In this design, because the second circuit board 600 can undergo a small range of deformation, it facilitates the positional arrangement of the first sensor 300 and the second sensor 400, reducing the assembly precision requirements for the first sensor 300 and the second sensor 400. Furthermore, since the electrical connection between the second circuit board 600 and the first circuit board 500 is sufficient to achieve the electrical connection between the first sensor 300 and the second sensor 400, the assembly steps with the first circuit board 500 are simplified. In other embodiments, both the first circuit board 500 and the second circuit board 600 can be flexible circuit boards.

[0120] In some embodiments, the capacitive touch recognition circuit 800 may include a first capacitive touch recognition circuit 800 and a second capacitive touch recognition circuit 800. The first capacitive touch recognition circuit 800 is electrically connected to a first sensor 300, and the second capacitive touch recognition circuit 800 is electrically connected to a second sensor 400. In this scheme, the first capacitive touch recognition circuit 800 can independently process the sensing signal sensed by the first sensor 300, and the second capacitive touch recognition circuit 800 can independently process the sensing signal sensed by the second sensor 400. The signal processing of the two is relatively independent of each other, resulting in lower circuit complexity and simpler manufacturing.

[0121] See Figures 1-20 The second aspect of this utility model also provides an accessory head 20 for detachably connecting to the skin treatment device 10 of any of the above-described embodiments. See details. Figures 11-21 The auxiliary head 20 includes a connector 21, a third sensor 22, and a fourth sensor 23. The connector 21 is detachably connected to the skin treatment device 10. The third sensor 22 is sensed by the second sensor 400, and the fourth sensor 23 senses the skin and is also sensed by the first sensor 300. In this design, the addition of the fourth sensor 23 serves as a relay component between the first sensor 300 and the skin sensing, thus improving the sensitivity of the first sensor 300 in sensing the skin. (See also...) Figure 21 In other embodiments, the auxiliary head 20 may not be equipped with the fourth sensor 23. By increasing the sensing sensitivity of the first sensor 300, the fourth sensor 23 can still directly sense the skin after the skin treatment device 10 is connected to the auxiliary head 20.

[0122] See Figures 14-15 In some embodiments, the fourth sensor 23 includes a first sensing part 231 and a second sensing part 232 electrically connected to each other. The first sensing part 231 is adapted to sense the skin, and the second sensing part 232 is adapted to be sensed by the first sensor 300. When the fourth sensor 23 is close to the skin, the capacitance between the first sensing part 231 and the outside environment changes, thereby generating an induced current in the fourth sensor 23. Consequently, the capacitance between the second sensing part 232 and the first sensor 300 changes, ultimately allowing the first sensor 300 to indirectly sense the skin through the fourth sensor 23. In some embodiments, the first sensing part 231 may be located on the side of the second sensing part 232 closer to the skin. In this configuration, the first sensing part 231 is more convenient for sensing the skin, and the second sensing part 232 is more convenient for sensing the first sensor 300. This allows for an increase in the size of the auxiliary head 20 along the centerline direction Z of the light outlet 1131, thereby improving the sensing range of the first sensor 300.

[0123] See Figures 14-15In some embodiments, both the first sensing part 231 and the second sensing part 232 may be annular, and both are connected to the side of the connector 21 facing the skin treatment device 10. The connector 21 is provided with a light-transmitting opening 211, and a filter for processing the high-energy light from the light-emitting component 240 may be provided inside the light-transmitting opening 211. Viewed along the center line Z of the light-emitting opening 1131, both the first sensing part 231 and the second sensing part 232 are arranged around the outer periphery of the light-transmitting opening 211. In this design, on the one hand, the annular structure of the first sensing part 231 can improve the sensing range of the first sensing part 231, so that when the auxiliary head 20 contacts the skin at any angle, the first sensing part 231 can effectively sense the skin, thus improving the sensing accuracy. On the other hand, the annular structure of the second sensing part 232 can improve the sensing range of the second sensing part 232, thereby making the position arrangement of the first sensing element 300 more flexible. On the other hand, both the first sensing element 231 and the second sensing element 232 are located on the outer periphery of the light-transmitting opening 211, which improves the concealment of the first sensing element 231 and the second sensing element 232. Furthermore, in this embodiment, when viewed along the center line direction Z of the light-emitting opening 1131, the first sensing element 231 can be located inside the second sensing element 232. This solution can further increase the sensing range of the second sensing element 232, thereby further facilitating the positional arrangement of the first sensing element 300.

[0124] See Figures 14-15 In some embodiments, the connector 21 is provided with a light-transmitting opening 211. Along the direction from the light-transmitting opening 211 to the skin treatment device 10, the connector 21 is inclined from the inside out towards the skin treatment device 10. In other words, the connector 21 is flared. On the one hand, the flared connector 21 can fit the external structure of the head shell 111; on the other hand, the flared connector 21 can increase the size of the head shell 111 extending into the connector 21, thereby improving the connection stability between the connector 21 and the head shell 111.

[0125] See Figures 1-21 The third aspect of this utility model also provides a skin treatment device 1, including the skin treatment apparatus 10 of any of the above claims and at least one auxiliary head 20 of any of the above claims. The specific structure and number of auxiliary heads 20 are configured according to the specific type of skin treatment apparatus 10. A skin treatment apparatus 10 may be matched with only one auxiliary head 20 or with multiple auxiliary heads 20 simultaneously, and one or more auxiliary heads 20 together with the skin treatment apparatus 10 constitute the skin treatment device 1. In view of the improvements to the skin treatment apparatus 10 and the auxiliary heads 20, the skin treatment device 1 in this embodiment has all the technical effects of the skin treatment apparatus 10 and the auxiliary heads 20 described above, which will not be elaborated here.

[0126] See Figures 4-8 ,as well as Figures 15-18 In some embodiments, the skin treatment device 10 includes a plurality of second sensors 400, each of which is electrically connected to a capacitive touch recognition circuit 800. Each second sensor 400 is configured to sense at least one accessory head 20 to identify the type of accessory head 20 based on the number and / or position of the accessory head 20. A connector 21 has a light-transmitting opening 211, and a third sensor 22 is connected to the connector 21. There are multiple accessory heads 20, and the third sensors 22 for different accessory heads 20 are respectively located on different sides of the outer periphery of the light-transmitting opening 211; each second sensor 400 is circumferentially distributed around the axis of the light-transmitting opening 211. This scheme can identify the type of accessory head 20, improving the accuracy of accessory head 20 identification.

[0127] See Figures 19-21 In some embodiments, the function output portion 110 has a width direction Y and a thickness direction X, and the width of the function output portion 110 is greater than the thickness of the function output portion 110; the outer peripheral plate 114 includes two first side plates 1141 located in the width direction Y of the function output portion 110 and two second side plates 1142 located in the width direction Y of the function output portion 110. The connector 21 includes two third side plates 212, wherein at least a portion of one third side plate 212 is located outside one of the second side plates 1142 in the width direction Y, and at least a portion of the other third side plate 212 is located outside the other second side plate 1142 in the width direction Y. At least one second side plate 1142 is connected to the second sensor 400, and at least one third side plate 212 is connected to the third sensor 22. In this design, the third side plate 212 of the auxiliary head 20 extends at least partially to one side of the second side plate 1142 along the width direction Y. This improves the connection stability of the auxiliary head 20 to the housing 100. Furthermore, the second sensor 400 and the third sensor 22 are further away from the skin, and their sensing directions are also more deviated from the first sensor 300. As a result, the mutual sensing between the second sensor 400 and the third sensor 22 is less susceptible to interference from the skin or the first sensor 300, thus improving the sensing accuracy.

[0128] It should be noted that if any directional indication (such as up, down, left, right, front, back, etc.) is involved in the embodiments of this utility model, such directional indication is only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indication will also change accordingly. When a directional reference is introduced in a specific embodiment, unless the direction is specifically limited to unidirectional, the direction can be unidirectional or bidirectional (two parallel and opposite directions). Whether it is unidirectional or bidirectional depends on what those skilled in the art can achieve. When the directional reference is bidirectional, it should be considered that two parallel and different embodiments have been introduced simultaneously.

[0129] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or," "and / or," or "and / or" throughout the text implies three parallel solutions. For example, "fourth sensing element 23 and / or B" includes the fourth sensing element 23 solution, solution B, or a solution where both fourth sensing elements 23 and B are satisfied. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0130] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
