Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0034] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] The multifunctional hair care comb provided by the utility model can have the functions of EMS (Electronic Muscle Stimulation) massage, scalp photography, medicine application, combing and massage, etc. Figure 1 and Figure 2 The multifunctional hair care comb of the utility model comprises: a comb body 10 and at least two functional heads, each functional head is detachably connected to the comb body 10, and each functional head can be used in combination with the comb body 10 to achieve care with different functions.

[0036] As shown in the figure, the comb body 10 includes a handle 11 and a comb head 12 located at one end of the handle 11. The comb head 12 is provided with a mounting groove 13 for mounting a functional head, so that the functional head is installed in the mounting groove 13 and can be combined and replaced through a detachable structure.

[0037] Optionally, the functional heads include two or three of the EMS massage functional head 21, the camera functional head 22, the liquid application functional head 23, and the combing tooth massage functional head (not shown in the figure). Preferably, the multifunctional hair care comb of the utility model includes the EMS massage functional head 21, the camera functional head 22, and the liquid application functional head 23, which can respectively realize EMS microcurrent massage of the skin (such as scalp, face, neck or other parts) after being installed with the comb body 10, take scalp images for the server (or related software) to perform scalp nutrition analysis, and apply liquid or essential oil in the liquid application functional head 23 to the skin (such as scalp).

[0038] In order to facilitate the control of various functions of the hair care comb, an identity identifiable part 24 is provided on the functional head, and the multifunctional hair care comb also includes an identity recognition module (not numbered in the figure), which is arranged in the comb body 10; when the functional head is connected to the comb body 10, that is, when the functional head is installed on the comb body 10, the identity recognition module can recognize the identity information of the identity identifiable part 24 on the functional head, and can control the working state of the functional head according to the identity information.

[0039] For example, when the identity recognition module recognizes that the functional head installed on the comb body 10 is the camera functional head 22, the camera and flash of the camera functional head 22 can be controlled to turn on, and when a photo-taking command is received (such as pressing the control key on the comb body 10), the camera is enabled to capture the user's scalp image and transmit it to the identity recognition module, which is then sent to the server (or cloud platform, etc.) for image processing and analysis. The user can view the analysis results and care plans through a mobile phone APP (Application) or mini-program.

[0040] The utility model enables one comb body to be used in combination with a plurality of functional heads by detachably mounting two or more functional heads on one comb body 10, and an identification member 24 is provided on each functional head, and an identification module is provided on the comb body 10. After the identification module identifies the identity information of the functional head, the working state of the functional head is controlled accordingly, so that the functions of the hair care comb are enriched, the purchase cost of consumers is reduced, and the storage space of the care comb is reduced, so that the care comb is easy to carry, and the user can also perform scalp or hair care during business trips.

[0041] Please also read Figure 3 , Figure 4 and Figure 5 The comb body 10 is provided with a locking tongue 14 and a control mechanism 15 for controlling the extension and retraction of the locking tongue 14. The control mechanism 15 is connected to the locking tongue 14 and can control the extension and retraction of the locking tongue 14. Each functional head is provided with a slide groove 25 that cooperates with the locking tongue 14. After the functional head is installed in the installation groove 13, a part of the locking tongue 14 can be extended into the slide groove 25 for assembly. After the control mechanism 15 controls the locking tongue 14 to retract, the functional head can be taken out and replaced with another functional head.

[0042] The slide groove 25 is arc-shaped, and its length is more than half of the circumference of the side of the functional head. There are two or more locking tongues 14, which are evenly distributed around the functional head with the center of the circle of the functional head as the center, so that the functional head and the installation groove 13 are not easy to loosen after installation, thereby facilitating care operations.

[0043] Optionally, the control mechanism 15 includes an unlocking key 151, a slider 152 and a connecting rod mechanism 153, the lower side of the unlocking key 151 has a slope 155, the slider 152 is provided with a through hole (not numbered in the figure), the unlocking key 151 is inserted into the through hole, the slope 155 is slidably matched with the bottom end of the through hole (such as the perspective of the granular soil 4), the connecting rod mechanism 153 has a rotating part 1531, which is connected to the comb body 10, and the connecting rod mechanism 153 can swing around the rotating part 1531 as the center.

[0044] Among them, one end of the connecting rod mechanism 153 is connected to the slider 152, and the other end of the connecting rod mechanism 153 is connected to the lock tongue 14. When the unlocking key 151 is pressed, the inclined surface 155 cooperates with the through hole to make the slider 152 slide toward the bottom end of the comb body 10, so that the connecting rod mechanism 153 moves. At this time, one end of the connecting rod mechanism 153 moves downward with the slider 152. Due to the action of the rotating part 1531, the other end of the connecting rod mechanism 153 swings toward the outside of the comb head 12, so that the lock tongue 14 shrinks, that is, the lock tongue 14 leaves the slide groove 25, so that the functional head can be removed from the comb body 10. After the external force of the unlocking key 151 disappears, the lock tongue 14 is reset by the spring 154 at the other end of the connecting rod mechanism 153. The lock tongue 14 has an inclined surface. When installing the functional head, you only need to press the functional head into the installation groove. The lock tongue 14 will shrink under the action of external force. When the functional head is installed in place, the spring 154 makes the lock tongue 14 extend into the slide groove 25. Of course, you can also shrink the lock tongue 14 and install it by pressing the unlocking key 151. The installation and disassembly method is simple.

[0045] Of course, other detachable structures such as threaded structure, buckle structure, etc. can also be used between the functional head and the comb body 10, and the utility model does not limit this. In addition, the utility model can also set mounting grooves 13 on both sides of the comb head to realize the solution of installing two functional heads on one comb body at the same time, further saving storage space.

[0046] Please also read Figure 6 In a further embodiment, each functional head is provided with an anti-idiot portion 26, and the comb body 10 is provided with an anti-idiot portion 156 for accommodating the anti-idiot portion 26. When the functional head is installed in the installation groove 13, the anti-idiot portion 26 is located in the anti-idiot portion 156. The anti-idiot design can ensure that the multi-function head and the comb body are correctly installed, and can prevent the input and output poles of the identity recognition module on the functional head and the comb body 10 from being reversed, thereby ensuring that the identity recognition module can reliably control the operation of the functional head.

[0047] Optionally, the foolproof groove 156 has a guide portion 1561 (such as Figure 3 As shown), the guide portion 1561 has a trumpet-shaped mouth (not numbered in the figure) to facilitate the anti-idiot portion 26 to be embedded in the anti-idiot groove 156.

[0048] Furthermore, the fool-proof groove 156 may also be provided with a locking tongue 14 , and a recessed portion 261 may be provided on the fool-proof portion 26 , so as to further improve the stability of the installation of the functional head and the combing head 12 .

[0049] The mounting slot 13 of the comb body 10 and the functional head are both provided with a plurality of conductive parts 157. The design of the foolproof part 26 and the foolproof slot 156 enables the conductive parts 157 of the two to be reliably electrically connected when the functional head is installed on the comb body 10, so that the electrical signal can be correctly transmitted, ensuring that the functions of the multifunctional hair care comb can be well realized. For example, after the EMS massage functional head 21 is installed on the comb body 10, the EMS driving signal output by the identity recognition module can be loaded onto the metal comb teeth 211 of the EMS massage functional head 21 through the conductive part 157, and when the metal comb teeth come into contact with the human body, micro-current can be output to act on the human skin for EMS massage. Since the EMS massage function, the camera function, the piston push liquid function, etc. are all functions that the existing care combs can have, and their implementation methods are not the protection points of the present utility model, the implementation methods of these functions are not described in detail here.

[0050] Please continue reading Figure 1 and Figure 2 The identity identifiable element 24 is an RFID tag or an NFC tag attached to the functional head. Since the RFID tag includes an RFID chip, identity information can be written into the RFID chip for reading by the identity recognition module; the NFC tag can also include an NFC chip, and identity information can be written into the NFC chip for reading by the identity recognition module. Since the method of writing identity information into the RFID chip and the NFC chip is a prior art, it will not be described in detail here.

[0051] In this embodiment, the identity recognition module is disposed on the circuit board of the comb body 10. Figure 7 and Figure 8 The identity recognition module includes a reading unit 27 and a control unit 28. The reading unit 27 is connected to the control unit 28. The control unit 28 includes a main control chip U1 and peripheral electronic components (such as resistors and capacitors). The main control chip U1 can adopt a microprocessor with model ZX32F018, which is mainly used to control the functions of the care comb, such as EMS massage, video recording, controlling the motor to rotate and push liquid, light therapy, motor vibration, etc. It has rich IO ports, which can facilitate the expansion of the functions of the care comb.

[0052] In this embodiment, the reading unit 27 is used to read the identity information of the RFID tag or NFC tag and feed it back to the control unit 28, and the control unit 28 controls the working state of the functional head according to the identity information. For example, when the reading unit 27 reads that the identity information of the RFID tag or NFC tag on the functional head is the camera functional head 22, the control unit 28 turns on the camera function on the functional head, takes a photo after receiving the photo command, and sends the captured image to the server or cloud platform via wired or wireless means. At this time, the corresponding program (such as a mobile phone APP) can be installed on a terminal such as a mobile phone to view the captured image and skin health status analysis results, care plans, etc.

[0053] In an optional embodiment, taking the identity identifiable element 24 as an attached RFID tag as an example, the reading unit 27 includes an antenna ANT, an NFC chip U2, a first resistor R1, a second resistor R2, a third resistor R3, a first capacitor C1, a second capacitor C2, a third capacitor C3, a fourth capacitor C4, a fifth capacitor C5, a sixth capacitor C6, a seventh capacitor C7 and an eighth capacitor C8. The NFC chip U2 can use a chip model MS520, which is a contactless near-field communication chip that can quickly read the identity information of the RFID tag.

[0054] In this embodiment, the antenna ANT can be a printed antenna, which occupies a small space. When it senses the RFID tag, the NFC chip can read the identity information of the RFID tag. The D5 pin, D6 pin, D7 pin, NSS pin and IRQ pin of the NFC chip U2 are connected to the control unit 28. Specifically: the D5 pin of the NFC chip U2 is connected to the 38th pin of the main control chip U1, the D6 pin of the NFC chip U2 is connected to the 39th pin of the main control chip U1, the D7 pin of the NFC chip U2 is connected to the 40th pin of the main control chip U1, the NSS pin of the NFC chip U2 is connected to the 37th pin of the main control chip U1, and the IRQ pin of the NFC chip U2 is connected to the 46th pin of the main control chip U1. Communication is carried out through the SPI bus, and its communication speed is fast.

[0055] One end of the antenna ANT is connected to one end of the first capacitor C1, one end of the second capacitor C2 and one end of the fourth capacitor C4 through the first resistor R1, the other end of the antenna ANT is connected to the other end of the first capacitor C1, one end of the third capacitor C3 and one end of the sixth capacitor C6 through the second resistor R2, the other end of the second capacitor C2 is grounded, and is also connected to the other end of the fourth capacitor C4, one end of the third resistor R3 and one end of the first inductor L1 through the fifth capacitor C5, the other end of the third capacitor C3 is grounded, and is also connected to the other end of the sixth capacitor C6 and one end of the second inductor L2 through the seventh capacitor C7, the other end of the first inductor L1 is connected to the TX2 pin of the NFC chip U2, the other end of the second inductor L2 is connected to the TX1 pin of the NFC chip U2, and the other end of the third resistor R3 is connected to the RX pin of the NFC chip U2 through the eighth capacitor C8.

[0056] Among them, the first resistor R1, the second resistor R2, and the first capacitor C1 constitute an RC filtering circuit, the first inductor L1 and the second, fourth, and fifth capacitors C2, C4, and C5, and the second inductor L2 and the third, sixth, and seventh capacitors C3, C6, and C7 respectively constitute LC filtering circuits, all of which can filter out unnecessary harmonics, so that the energy carrier signal generated after the antenna ANT and the RFID tag are sensed is smoother, thereby facilitating the NFC chip U2 to read and identify the identity information.

[0057] The reading unit 27 further includes a fourth resistor R4 and a ninth capacitor C9, which also form an RC filter circuit for filtering out spike signals to make the RF signal input to the RX pin of the NFC chip U2 smoother. The RX pin of the NFC chip U2 is also connected to the VMID pin of the NFC chip U2 and one end of the ninth capacitor C9 through the fourth resistor R4, and the other end of the ninth capacitor C9 is grounded.

[0058] Of course, in other embodiments, other identification methods may also be used to identify the identity information of the functional head, such as using a Hall sensing method, by installing magnets at different positions of different functional heads, setting a Hall sensor on the comb body, and using the Hall sensor to sense the position of the magnet to achieve identification of the functional head. The utility model cites the RFID identification method, which should not be understood as a limitation to the utility model.

[0059] Furthermore, the reading unit 27 also includes a crystal oscillator Y1, a tenth capacitor C10 and an eleventh capacitor C11, the first pin of the crystal oscillator Y1 is connected to the fourth pin of the crystal oscillator Y1 and the ground through the tenth capacitor C10, and the second pin of the crystal oscillator Y1 is connected to the third pin of the crystal oscillator Y1 and the OSCOUT pin of the NFC chip U2 through the eleventh capacitor C11. The crystal oscillator Y1 can generate a 27.12MHz clock signal, which can output a 13.56MHz clock signal after being divided by the first capacitor C1 and the eleventh capacitor C11, and can be used as a system clock to ensure that the identity recognition module works reliably.

[0060] In an optional embodiment, when the function head is installed in the installation slot 13, the RFID tag on the function head performs near field communication with the reading unit 27. At this time, the antenna ANT and the RFID tag sense and generate a carrier signal, which is input into the NFC chip U2 after being filtered by the RC circuit and the LC circuit. The NFC chip U2 identifies the identity information of the RFID tag and feeds it back to the main control chip U1 in the SPI communication mode. The main control chip U1 controls the function head to perform the corresponding function according to the identity information, such as outputting an EMS drive signal with a corresponding duty cycle through the 23rd or 24th pin of the main control chip U1, turning on the flash light through the 9th, 10th or 11th pin, controlling the on state of the camera through the 8th pin, controlling the forward and reverse state of the push motor through the 27th pin, etc. These drive signals are transmitted to the function head through the conductive part 157, so that the corresponding function head performs the corresponding work.

[0061] In summary, the utility model enables one comb body to be used in combination with multiple functional heads by detachably installing more than two functional heads on one comb body, and an identity identifiable part is provided on each functional head, and an identity recognition module is provided on the comb body. After the identity recognition module recognizes the identity information of the functional head, the working state of the functional head can be controlled accordingly, thereby enriching the functions of the hair care comb, reducing the purchase cost for consumers, and reducing the storage space of the care comb, making it easy to carry.

[0062] In addition, RFID tags or NFC tags are used for identity recognition, which is reliable. The thickness of the RFID tags or NFC tags can be less than 1 mm, which reduces the structural complexity of the functional head, and can reduce the mold cost and assembly cost of the functional head. In addition, there is no need to make direct conductive contact between the functional head and the comb body during identity recognition, so there is no need to consider waterproof design, and the functional adaptability range is wider.

[0063] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
