Description

Technical Field

[0001] The present disclosure relates to the technical field of hairdressing equipment, and in particular to a hairdressing equipment. Background Art

[0002] As people's living standards improve, the pursuit of haircut effects is also increasing. When using a hair cutting device to trim hair, due to different hairstyles, the length of hair required to be trimmed is different at different positions on the head of the barber.

[0003] In the related art, the current method of changing and modifying the length of hair through hairdressing equipment is relatively complicated, and now more and more users choose to do their own hairdressing, which also makes it difficult for users to easily change the length of trimmed hair, resulting in not getting the ideal hairstyle of the barber, affecting the user experience. Utility Model Content

[0004] In view of this, the present disclosure provides a hair cutting device that can conveniently change the length of trimmed hair and improve the user experience.

[0005] Specifically, the present disclosure is achieved through the following technical solutions:

[0007] The technical solutions provided by the embodiments of the present disclosure may have the following beneficial effects:

[0008] When using this haircutting device for haircutting, the haircutting device moves on the user's head, and the abutment abuts the user's head, so that the cutter head assembly can cut the user's hair. The telescopic mechanism is connected to the cutter head assembly via a telescopic end. When the length of the trimmed hair needs to be changed, the telescopic mechanism drives the second cutter head assembly to move relative to the abutment via the telescopic end. The cutter head assembly includes a first cutter and a second cutter. The relative sliding between the first cutter and the second cutter can cut the user's hair. Therefore, the drive assembly drives the first cutter and the second cutter to move synchronously relative to the abutment.

DETAILED DESCRIPTION

[0037] Here, the technical solutions in the embodiments (or "implementations") of the present application will be clearly and completely described in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0038] If there are terms related to directional indications or positional relationships in the embodiments of this application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, height, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between the components in a specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first" and "second" in the embodiments of this application are only used for the purpose of convenience of description and should not be understood as indicating or implying relative importance.

[0039] As people's living standards improve, their pursuit of haircutting results is also increasing. As an important tool for haircutting, haircutting equipment is becoming more and more common. However, with a wide variety of types and brands, consumers have many choices. How to win the favor of consumers and improve product competitiveness has become an issue that haircutting equipment manufacturers are paying more and more attention to.

[0040] Based on this, the present disclosure provides a hairdressing device 10, such as Figures 1 to 4 As shown, in some embodiments, the hair cutting device 10 includes a housing assembly 100 and a cutting module 200. The housing assembly 100 is provided with an abutment 101. The cutting module 200 includes a cutting head assembly 210 and a telescopic mechanism 201. The telescopic mechanism 201 includes a telescopic end 2011, which is connected to the cutting head assembly 210 to drive the cutting head assembly 210 to move relative to the abutment 101.

[0041] Thus, when using the haircutting device 10 for haircutting, the device 10 moves along the user's head, and the abutment member 101 abuts the user's head, allowing the cutter head assembly 210 to cut the user's hair. The telescopic mechanism 201 is connected to the cutter head assembly 210 via the telescopic end 2011. When the length of the hair to be trimmed needs to be changed, the telescopic mechanism 201 drives the cutter head assembly 210 to move relative to the abutment member 101 via the telescopic end 2011 to change the length of the hair to be trimmed. This haircutting device 10 allows for convenient changes in the length of the hair to be trimmed, enhancing the user experience.

[0042] like Figures 1 to 4 As shown, in some embodiments, the abutment member 101 includes a matching comb 400, and the cutter head assembly 210 includes a first cutter 211 and a second cutter 212 movably connected to the first cutter 211. The telescopic end 2011 is connected to the cutter head assembly 210 to drive the first cutter 211 and the second cutter 212 to move relative to the matching comb 400.

[0043] Thus, when using the haircutting device 10 for haircutting, the device 10 moves along the user's head, with the comb 400 abutting the user's head, allowing the cutter head assembly 210 to cut the user's hair. The telescopic mechanism 201 is connected to the cutter head assembly 210 via the telescopic end 2011. When the length of the hair to be trimmed needs to be changed, the telescopic mechanism 201 drives the cutter head assembly 210 to move relative to the comb 400 via the telescopic end 2011. The cutter head assembly 210 includes a first blade 211 and a second blade 212. The relative sliding movement between the first blade 211 and the second blade 212 enables trimming of the user's hair. Therefore, the drive assembly drives the first blade 211 and the second blade 212 to move synchronously relative to the comb 400. In other words, the first blade 211 and the second blade 212 move synchronously relative to the user's head to change the length of the hair to be trimmed. The haircutting device 10 allows for convenient changes in the length of the hair to be trimmed, enhancing the user experience.

[0044] like Figures 1 to 3 As shown, in some embodiments, the hair cutting device 10 further includes a displacement detection assembly 300 and a controller 700. The displacement detection assembly 300 is disposed within the housing assembly 100 and is configured to detect the travel distance of the abutment 101. The controller 700 is in communication with the telescopic mechanism 201. The controller 700 can control the telescopic mechanism 201 to drive the cutter head assembly 210 to telescope toward or away from the abutment 101 based on the travel distance of the abutment 101. Thus, when using the hair cutting device 10 for haircutting, the device 10 moves across the user's head, and the abutment 101 abuts the user's head, allowing the cutter head assembly 210 to cut the user's hair. The displacement detection assembly 300 can detect the distance the abutment 101 moves on the user's head, and the telescopic mechanism 201 is connected to the cutter head assembly 210 via the telescopic end 2011, thereby driving the cutter head assembly 210 to move relative to the abutment 101. The controller 700 can obtain the distance of the abutment 101, and the controller 700 is in communication with the telescopic mechanism 201, so that the controller 700 can control the telescopic mechanism 201 to drive the cutter head assembly 210 to move toward or away from the abutment 101 based on the distance of the abutment 101. This allows the cutter head assembly 210 to change the distance from the user's head based on the distance of the abutment 101, thereby enabling the hair cutting device 10 to automatically control the haircut length at different positions on the head, thereby improving the accuracy of the haircut length and enhancing the user experience.

[0045] When using the haircutting device 10 of the present application, the user places the haircutting device 10 on their head and moves it regularly. The displacement detection component 300 records the distance the haircutting device 10 moves on the user's head. The controller 700 controls the telescopic mechanism 201 to drive the cutter head assembly 210 up and down based on the acquired displacement, thereby automatically controlling the length of hair cut at different locations on the head. Furthermore, the user can select their preferred hairstyle (e.g., by selecting a hairstyle on a terminal device or the haircutting device 10). The haircutting device 10 can adjust the haircut length corresponding to the different displacement information based on the user's selected hairstyle, thereby trimming the user's selected hairstyle.

[0046] It should be noted that the telescopic mechanism 201 includes devices that directly provide telescopic power, such as a telescopic motor, a pneumatic lever, and a hydraulic cylinder. Of course, the telescopic mechanism 201 may also include devices that indirectly provide telescopic power.

[0047] like Figures 3 to 5 As shown, in some embodiments, the telescopic mechanism 201 includes a first power source 230 and a transmission assembly 220. The first power source 230 is connected to the cutter head assembly 210 through the transmission assembly 220 to drive the first knife 211 and the second knife 212 to move telescopically toward or away from the abutment 101.

[0048] It should be noted that there may be many specific implementations of the first power source 230 , including but not limited to a motor and its derivatives.

[0049] like Figures 3 to 7 As shown, in some embodiments, the cutting module 200 further includes a connecting assembly 240, the cutter head assembly 210 is disposed on the connecting assembly 240, the first power source 230 is in transmission connection with the transmission assembly 220, and the transmission assembly 220 is in transmission connection with the connecting assembly 240. In this way, the first power source 230 drives the connecting assembly 240 to move through the transmission assembly 220, and the cutter head assembly 210 is disposed on the connecting assembly 240, so that when the first power source 230 drives the connecting assembly 240 to move, the second cutter head assembly 212 is simultaneously driven to move relative to the housing assembly 100, thereby driving the first cutter 211 and the second cutter 212 to move synchronously relative to the housing assembly 100.

[0050] like Figure 3 As shown, in some embodiments, the transmission assembly 220 includes a first transmission member 221 and a second transmission member 222 that is transmission-connected to the first transmission member 221, one of the first transmission member 221 and the second transmission member 222 is fixedly connected to the first power source 230, and the other is fixedly connected to the connecting assembly 240.

[0051] It should be noted that one of the first transmission member 221 and the second transmission member 222 is fixedly connected to the first power source 230, and the other is fixedly connected to the connecting assembly 240, including the first transmission member 221 being fixedly connected to the first power source 230, the second transmission member 222 being fixedly connected to the connecting assembly 240, and the second transmission member 222 being fixedly connected to the first power source 230, and the first transmission member 221 being fixedly connected to the connecting assembly 240.

[0052] Taking the example of a case where the first transmission member 221 is fixedly connected to the first power source 230 and the second transmission member 222 is fixedly connected to the connecting assembly 240, the first power source 230 drives the first transmission member 221, which is in transmission connection with the second transmission member 222 to drive the second transmission member 222. The second transmission member 222 is fixedly connected to the connecting assembly 240 so that the first power source 230 drives the connecting assembly 240 to move along the housing assembly 100 via the first transmission member 221 and the second transmission member 222.

[0053] like Figure 3 As shown, in some embodiments, the first power source 230 includes a first output portion 231, which is fixedly connected to the first transmission member 221. The first transmission member 221 can rotate under the drive of the first power source 230. The second transmission member 222 is fixedly connected to the connecting assembly 240. The second transmission member 222 can reciprocate linearly under the drive of the first transmission member 221. In this manner, the first power source 230 is fixedly connected to the housing assembly 100 as a whole, for example, the first power source 230 is mounted on the housing assembly 100. The first output portion 231 of the first power source 230 serves as a power output end and is fixedly connected to the first transmission member 221 to drive the first transmission member 221 to rotate. The first transmission member 221 is in transmission connection with the second transmission member 222, converting the rotational motion of the first transmission member 221 into reciprocating linear motion of the second transmission member 222. The second transmission member 222 is fixedly connected to the connecting assembly 240, so that the connecting assembly 240 drives the second cutter head assembly 212 to reciprocate linearly.

[0054] like Figures 3 to 7As shown, in some embodiments, the first transmission member 221 includes a screw rod 2211, and the second transmission member 222 includes a nut 2221. The screw rod 2211 is fixedly connected to the first power source 230 and can be driven to rotate by the first power source 230. The nut 2221 is fixedly connected to the connecting assembly 240, and the nut 2221 and the screw rod 2211 are threadedly engaged. The connecting assembly 240 abuts against the housing assembly 100 to limit the rotation of the connecting assembly 240 relative to the screw rod 2211, so that the connecting assembly 240 can perform reciprocating linear motion along the screw rod 2211. Taking the first power source 230 as an example, the output shaft of the motor is fixedly connected to the first transmission member 221, that is, the screw rod 2211. At this time, the output shaft of the motor can rotate synchronously with the screw rod 2211, and the nut 2221 is fixedly connected to the connecting assembly 240. The screw rod 2211 and the nut 2221 are threadedly engaged, so that the screw rod 2211 can drive the nut 2221 to move. Under the action of the connecting assembly 240 abutting against the housing assembly 100 to limit the rotation of the connecting assembly 240 relative to the screw rod 2211, the nut 2221 reciprocates along the screw rod 2211, thereby causing the cutter head assembly 210 to reciprocate along the screw rod 2211.

[0055] like Figure 8 As shown, in some embodiments, the housing assembly 100 includes a housing cavity 110, and the connecting assembly 240, transmission assembly 220, and first power source 230 are disposed within the housing cavity 110. The connecting assembly 240 is slidably connected to the inner sidewall of the housing cavity 110, enabling the connecting assembly 240 to telescopically move toward or away from the abutment 101. Thus, by disposing the connecting assembly 240, transmission assembly 220, and first power source 230 within the housing cavity 110 of the housing assembly 100, the overall structure of the hairdressing device 10 can be made compact, achieving a miniaturized design. When the first power source 230, via the transmission assembly 220, drives the connecting assembly 240 to telescopically move toward or away from the abutment 101, the connecting assembly 240 is slidably connected to the inner sidewall of the housing cavity 110, improving the reliability of the telescopic movement of the connecting assembly 240.

[0056] like Figure 5 as well as Figure 6 As shown, in some embodiments, the connecting assembly 240 further includes a connecting body 241 and a plurality of rollers 242 rotatably connected to the connecting body 241. The inner sidewall of the accommodating cavity 110 is provided with a slide rail 102 that cooperates with the rollers 242. The plurality of rollers 242 are disposed on opposite sides of the connecting body 241 and are in rolling connection with the slide rail 102. Thus, when the first power source 230 is in transmission connection with the connecting assembly 240 via the transmission assembly 220, the rolling connection between the rollers 242 and the slide rail 102 further improves the reliability of the telescopic movement of the connecting assembly 240.

[0057] Furthermore, since the rollers 242 are in rolling connection with the slide rail 102, the connecting assembly 240 cannot rotate relative to the screw rod 2211, allowing the connecting assembly 240 to perform reciprocating linear motion along the screw rod 2211 under the action of the nut 2221. Furthermore, by rotatably connecting multiple rollers 242 to the main body of the connecting assembly 240, the multiple rollers 242 are respectively in rolling connection with the inner sidewalls of the accommodating cavity 110, thereby facilitating the reciprocating linear motion of the connecting assembly 240 relative to the housing assembly 100 along the screw rod 2211.

[0058] like Figure 9 As shown, in other embodiments, the first transmission member 221 includes a driving gear 2212, and the second transmission member 222 includes a driven rack 2222. The driving gear 2212 is fixedly connected to the first output portion 231, and the driving gear 2212 can be driven to rotate by the first output portion 231. The driven rack 2222 is fixedly connected to the connecting assembly 240, and the driving gear 2212 and the driven rack 2222 are meshed and transmission-coordinated. In this way, the first output part 231 of the first power source 230 is fixedly connected to the driving gear 2212, so that the driving gear 2212 rotates under the drive of the first output part 231, and the driving gear 2212 is engaged with the driven rack 2222 to transmit the rotational motion of the driving gear 2212 into the linear motion of the driven rack 2222, and the driven rack 2222 is fixedly connected to the connecting assembly 240, thereby driving the connecting assembly 240 to perform reciprocating linear motion, so that the cutter head assembly 210 can perform reciprocating linear motion relative to the housing assembly 100.

[0059] Of course, it is understandable that in addition to the screw 2211, nut 2221, and gear rack transmission method, there are many other specific implementation methods of the first transmission member 221 and the second transmission member 222, which can enable the cutter head assembly 210 to perform reciprocating linear motion relative to the shell assembly 100, and they will not be repeated here.

[0060] like Figure 3As shown, in some embodiments, the connecting assembly 240 is provided with a receiving cavity 243, and the cutting module 200 further includes a second power source 250, which is located within the receiving cavity 243. The second power source 250 includes a second output portion 251, which is fixedly connected to the second blade 212. The second blade 212 can be driven by the second power source 250 to slide relative to the first blade 211. Thus, when the hair cutting device 10 is in operation, the second output portion 251 of the second power source 250 is fixedly connected to the second blade 212, allowing the second blade 212 to slide relative to the first blade 211 under the drive of the second output portion 251, thereby cutting hair. Placing the second power source 250 within the receiving cavity 243 helps improve the overall compactness of the hair cutting device 10, achieving a miniaturized design.

[0061] It should be noted that there may be many specific implementations of the second power source 250 , including but not limited to a motor and its derivatives.

[0062] In the practice of this application, researchers found that although the first power source 230 can drive the cutter head assembly 210 to move relative to the housing assembly 100, thereby changing the cut hair length, this method mainly drives the cutter head assembly 210 as a whole to move relative to the housing assembly 100 when the hair cutting device 10 moves the user's head, making it difficult to achieve fine-tuning of the cut hair length.

[0063] like Figure 6 as well as Figure 7 As shown, in some embodiments, the cutting module 200 further includes a first adjustment assembly (not shown) and a second blade holder 213 connected to the first adjustment assembly. A second blade 212 is mounted on the second blade holder 213. The first adjustment assembly controls the movement of the second blade holder 213 to adjust the inter-tooth distance between the second blade 212 and the first blade 211. Thus, when fine-tuning the length of the cut hair is required, the first adjustment assembly is adjusted to move the second blade holder 213, causing the second blade 212 to move relative to the first blade 211, thereby adjusting the distance between the ends of the second blade 212 and the first blade 211 to change the cut hair length.

[0064] Of course, if Figure 6 as well as Figure 7As shown, in other embodiments, the cutting module 200 may also include a second adjustment assembly (not shown) and a first blade holder 214 connected to the second adjustment assembly. The first blade 211 is mounted on the first blade holder 214, and the second adjustment assembly is capable of controlling the movement of the first blade holder 214 to adjust the distance between the ends of the second blade 212 and the first blade 211. Thus, when fine-tuning the length of the cut hair is required, the second adjustment assembly is adjusted to move the first blade holder 214, causing the second blade 212 to move relative to the first blade 211, thereby adjusting the distance between the ends of the second blade 212 and the first blade 211 to change the length of the cut hair.

[0065] The first adjustment component or the second adjustment component is used to adjust the distance between the end of the second blade 212 and the end of the first blade 211 to change the length of the cut hair, allowing the user to better control the length of the cut hair, which is conducive to improving the user experience. The adjustment method using the first adjustment component or the second adjustment component can be toggling, twisting, sliding, rotating, etc., which is not further limited in this application.

[0066] like Figure 1 、 Figures 2 to 10 As shown, in some embodiments, the abutment member 101 includes a comb 400, which is connected to the housing assembly 100. The comb 400 includes a comb body 410, a plurality of comb teeth 420 spaced apart on the comb body 410, and a connector 430. The displacement detection assembly 300 is disposed on the connector 430, which is connected to the comb body 410. Thus, when the hairdressing device 10 is used for haircutting, the comb 400 abuts the user's skin. At this time, the displacement detection assembly 300 abuts the user's skin, enabling the displacement detection assembly 300 to obtain displacement information of the hairdressing device 10 during haircutting. The comb 400 has a simple structure, and the method for obtaining displacement information of the hairdressing device 10 using the comb 400 is simple. The comb 400 is detachably connected to the housing assembly 100 of the hairdressing device 10, which improves the convenience of replacing the comb 400.

[0067] like Figure 8 、 Figure 10 as well as Figure 11 As shown, in some embodiments, the matching comb 400 is detachably connected to the housing assembly 100. The comb body 410 is provided with a buckle 411, and the housing assembly 100 is provided with a slot 120. The matching comb 400 engages with the slot 120 via the buckle 411 to achieve a detachable connection with the housing assembly 100. In this manner, the comb body 410 and the housing assembly 100 are detachably connected by engaging the buckle 411 with the slot 120. This detachable connection method facilitates disassembly, has high connection reliability, and is easy to implement.

[0068] like Figure 10 As shown, in some embodiments, the connecting member 430 is rotatably connected to the comb body 410 and has an initial state and a detection state. The connecting member 430 can be reset to the initial state. When the connecting member 430 is in the initial state, a first angle is formed between the connecting member 430 and the comb teeth 420. When the connecting member 430 is in the detection state, a second angle is formed between the connecting member 430 and the comb teeth 420 that is smaller than the first angle.

[0069] Thus, when using the hairdressing device 10 for haircutting, the comb 400 comes into contact with the user's skin, and the displacement detection assembly 300 can come into contact with the user's skin and detect the travel distance of the comb 400. The comb 400 has a simple structure, and the method for using the comb 400 to detect its travel distance is simple. When the comb 400 is not in contact with the user's skin, the connector 430 is in an initial state, at which point a first angle is formed between the connector 430 and the comb teeth 420. When the comb 400 comes into contact with the user's skin, the connector 430 enters a detection state. When force is applied to the hairdressing device 10, the connector 430 is subjected to the force and rotates relative to the comb body 410, causing the angle between the connector 430 and the comb teeth 420 to decrease to a second angle. At this time, the connecting member 430 has a reset force to reset to the initial state, so that the displacement detection component 300 can better adhere to the user's skin and can adapt to the head shape of different users, thereby improving the accuracy of the displacement detection component 300 in detecting the moving distance of the comb 400.

[0070] It should be noted that when the connecting member 430 is in the initial state, the first angle between the connecting member 430 and the comb teeth 420 is as follows: Figure 4 Angle a shown.

[0071] like Figure 10As shown, in some embodiments, the comb teeth 420 include a support portion 421 and a stopper portion 422 bent and connected to the support portion 421. A receiving groove 423 is formed between the stopper portion 422 and the support portion 421. The receiving groove 423 is used to accommodate hair. Thus, when using the hairdressing device 10 for haircutting, the support portion 421 of the comb teeth 420 is designed to abut against the user's head. As the hairdressing device 10 moves, the support portion 421 always abuts the user's head, allowing the first power source 230 of the cutter head assembly 210 to accurately cut hair. The receiving groove 423 formed between the support portion 421 and the stopper portion 422 can accommodate the user's hair, preventing hair from slipping out of the comb 400 during the haircutting process, resulting in uncut hair and the need for repeated trimming. When the hair cutting device 10 is moved on the user's head, the limiting portion 422 can make it easier for hair to enter the accommodating groove 423. Using the accommodating groove 423 to accommodate hair can improve the cutting efficiency of the hair cutting device 10.

[0072] Of course, in some embodiments, the hair cutting device 10 further includes a hair suction device, through which hair can enter the accommodating groove 423 to cut the hair in the accommodating groove 423.

[0073] It should be noted that there are many specific implementation methods of the hair suction device, including wind suction method, crawler transmission method, roller transmission method, etc.

[0074] Furthermore, when designing the structure of the comb teeth 420, the researchers found that the difference in length between the various limiting portions 422 would affect the reliability of the accommodating groove 423 in accommodating the user's hair. Therefore, the researchers designed the lengths between the different limiting portions 422.

[0075] like Figure 10 As shown, in some embodiments, the plurality of comb teeth 420 include a plurality of corresponding limiting portions 422 , the plurality of limiting portions 422 are spaced apart, and the length of at least two limiting portions 422 is greater than the length of the other limiting portions 422 .

[0076] like Figure 10 As shown in FIG, in one example, the lengths of the limiting portions 422 are two different types, wherein two longer limiting portions 422 are located on both sides, and two shorter limiting portions 422 are sandwiched between the two longer limiting portions 422. Figure 8 When designing the structure of the comb teeth 420 , researchers found that this design method can better facilitate the accommodating groove 423 to accommodate the user's hair.

[0077] It should be noted that there are many specific implementations of the displacement detection component 300, including a magnetic displacement sensor, a photoelectric sensor, and the like.

[0078] like Figure 10 As shown, in some embodiments, the connector 430 includes a connecting portion 431 rotatably connected to the comb body 410 and a rotating portion 432 rotatably connected to the connecting portion 431. The displacement detection assembly 300 includes a magnetic displacement sensor 310 disposed on the connecting portion 431 and a magnet 320 fixed to the rotating portion 432. The magnetic displacement sensor 310 and the magnet 320 are capable of generating electromagnetic induction. Thus, when the hairdressing device 10 is used for haircutting, the rotating portion 432 abuts the user's head while being rotatably connected to the connecting portion 431, allowing the rotating portion 432 to roll relative to the user's head. By disposing the magnet 320 within the rotating portion 432 and the magnetic displacement sensor 310 within the connecting portion 431, which is capable of generating electromagnetic induction with the magnet 320, the magnetic displacement sensor 310 can detect the distance the rotating portion 432 rolls relative to the user's head, thereby obtaining displacement information of the hairdressing device 10 on the user's head. Based on the acquired displacement information, the first power source 230 is controlled to drive the cutter head assembly 210 to cut hair. The connecting portion 431 is rotatably connected to the comb body 410. When force is applied to the hair cutting device 10 during haircutting, the connecting portion 430 rotates relative to the comb body 410, causing the supporting portion 421 of the comb 400 to abut against the user's head, facilitating hair cutting.

[0079] By arranging the displacement detection assembly 300 on the matching comb 400 , which is detachably connected to the housing assembly 100 , it is convenient to replace the displacement detection assembly 300 .

[0080] like Figure 10 As shown, in one example, two connecting members 430 are included, and two displacement detection assemblies 300 are included. The displacement detection assemblies 300 are respectively provided on the connecting members 430 in a one-to-one correspondence. The two connecting members 430 are respectively provided on either side of the comb teeth 420, so that the displacement detection assemblies 300 are located on either side of the comb teeth 420. In this way, two displacement detection assemblies 300 are provided on the matching comb 400, and the two displacement detection assemblies 300 are respectively provided on either side of the comb teeth 420. When the hairdressing device 10 is used for haircutting, the two displacement detection assemblies 300 obtain displacement information of the hairdressing device 10, which can improve the reliability of the displacement information.

[0081] like Figure 10As shown, in some embodiments, the plurality of comb teeth 420 include two conductive comb teeth 424. When the two conductive comb teeth 424 are electrically connected, the displacement detection component 300 begins detecting the movement distance of the accessory comb 400. Thus, when the hairdressing device 10 is used for haircutting, when the two conductive comb teeth 424 are electrically connected, the displacement detection component 300 is informed that the hairdressing device 10 has started cutting hair, and the detection component detects the movement distance of the accessory comb 400. This method automatically controls the displacement detection component 300 to obtain displacement information of the hairdressing device 10 and trim hair based on the displacement information, thereby improving the automation level of the hairdressing device 10 and enhancing the user experience.

[0082] It is understandable that the number of the conductive comb teeth 424 can be set according to the actual needs of the user, and can include one, two, three or four conductive comb teeth 424.

[0083] It should be noted that there are many ways to achieve electrical connection between the two conductive comb teeth 424, including directly contacting the conductive comb teeth 424 with the user's skin to achieve electrical connection between the two conductive comb teeth 424, or achieving electrical connection between the two conductive comb teeth 424 through other tools.

[0084] like Figure 12 As shown, in some embodiments, the hairdressing device 10 further includes a headgear 500, which includes a conductive headband 510. The headgear 500 is worn on the user's head via the conductive headband 510. When the conductive comb teeth 424 abut the conductive headband 510, the displacement detection assembly 300 begins detecting the movement distance of the comb 400. Thus, when using the hairdressing device 10 for haircutting, the headgear 500 is first worn on the user's head, at which point the conductive headband 510 is also positioned around the user's head (the user can then position the conductive headband 510 to a suitable location as the starting point for haircutting). Once the conductive headband 510 is positioned, the conductive comb teeth 424 of the hairdressing device 10 abut against the conductive headband 510, enabling electrical communication between the two conductive comb teeth 424.

[0085] It is understandable that in the hands of some users who are not proficient in hairdressing skills, the head-mounted device 500 can help users determine the starting point of haircutting. The user only needs to place the haircutting device 10 on the conductive hairband 510 first, and then move the haircutting device 10 on the head. Since during the movement of the haircutting device 10, the first power source 230 can control the movement of the cutter head assembly 210 according to the displacement information of the haircutting device 10 to cut the target hair length, the user's operation workload is greatly reduced, and the user can achieve self-service haircutting.

[0086] Of course, some skilled barbers can determine their own starting point for haircutting. In this case, the user does not need to wear the head-mounted device 500 during haircutting. When the user places the head-mounted device 500 at the appropriate starting point, the user can activate the displacement detection assembly 300 to begin acquiring displacement information of the haircutting device 10. The first power source 230 controls the movement of the cutter head assembly 210 based on the displacement information of the haircutting device 10 to cut the hair to the target length. This also greatly reduces the user's operation workload and ensures a more accurate hair cut length.

[0087] like Figure 12 As shown, in some embodiments, the head-mounted device 500 further includes a plurality of abutting portions 520, each of which can abut against the user's forehead and cheeks. Thus, when the user wears the head-mounted device 500, the abutting portions 520 abut against the user's forehead and cheeks, respectively, to provide a positioning function, thereby improving the wearing position accuracy of the head-mounted device 500.

[0088] like Figure 12 As shown, in some embodiments, the head-mounted device 500 further includes a third adjustment component 530, which is used to adjust the size of the conductive headband 510. Thus, when a user wears the head-mounted device 500, the user can adjust the size of the conductive headband 510 through the third adjustment component 530, thereby adjusting the tightness of the head-mounted device 500 on the user's head, thereby improving the user experience.

[0089] It should be noted that there are many specific implementation methods for the third adjustment component 530, including adjustment methods such as toggling, twisting, sliding, and rotating.

[0090] like Figure 10 As shown, in some embodiments, the conductive comb teeth 424 are rotatably connected to the comb body 410. When the connector 430 is in the initial state, the conductive comb teeth 424 and the comb teeth 420 have a third angle therebetween. When the connector 430 is in the detection state, the conductive comb teeth 424 and the comb teeth 420 have a fourth angle therebetween that is smaller than the third angle, and a force is provided to return the conductive comb teeth 424 to the third angle. Thus, when the comb 400 is not in contact with the user's skin, the connector 430 is in the initial state, at which point the conductive comb teeth 424 and the comb teeth 420 have the third angle therebetween. When the comb 400 is in contact with the user's skin, the connector 430 is in the detection state. When force is applied to the hairdressing device 10, the conductive comb teeth 424 are subjected to the force and rotate relative to the comb body 410, causing the angle therebetween to decrease to the fourth angle. At this time, the conductive comb teeth 424 have a reset force to reset to the third angle, so that the conductive comb teeth 424 can better adhere to the user's skin and can adapt to the head shapes of different users to better trigger the displacement detection component 300 for detection.

[0091] It should be noted that when the connecting member 430 is in the initial state, the third angle between the conductive comb teeth 424 and the comb teeth 420 is as follows: Figure 4 Angle b shown.

[0092] like Figure 10 As shown, in some embodiments, the comb 400 is further provided with a connection port 440 , and the displacement detection component 300 is electrically connected to the hairdressing device 10 via the connection port 440 to achieve charging and / or communication connection.

[0093] In some embodiments, the hair cutting device 10 may include a storage module 600 storing a plurality of hairstyle data. The user may select one of the plurality of hairstyle data as a target hairstyle, and the hair cutting device 10 performs hair cutting according to the target hairstyle data.

The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this application shall be included in the scope of protection of this application.
