Description

[0002] With the progress of the economy and society, more and more people will consider timeliness, hygiene and economy in life, which makes people do their own haircuts at home more and more, and various smart hair clippers have appeared on the market. In order to reduce the difficulty of home haircuts, the user's head contour is generally scanned by a light scanning device to obtain a corresponding head contour model, and then the user is assisted by a smart terminal to guide the user to complete self-haircuts through a smart hair clipper. However, the method of scanning the head contour by a light scanning device is easily affected by the user's hair and external factors, resulting in large errors in the obtained head contour data. In addition, the existing smart hair clippers are relatively complex in structure, and the steps of haircut operations are cumbersome, which easily causes users to forget the next step.

The second angular velocity sensor 80 is used to detect the second Euler angle data when the trimmer trims the head trimming area corresponding to the trimming indication area 1402.

The limit comb 130 is connected to an adjustment mechanism, and the adjustment mechanism is used to drive the limit comb 130 to adjust the position according to the hairstyle data.

[0048] In the fully automatic hair trimmer of the present embodiment, a collection mechanism 40 is provided to collect the stroke length data and the first Euler angle data during the movement of the collection housing 20, and all the collected stroke length data and the first Euler angle data are processed and simulated to form a head contour model 10 through the contour model forming module 170. The head collector can accurately simulate the user's head contour data by simultaneously collecting the stroke length data and the first Euler angle data; the hairstyle data of each trimming indication area 1402 is set in the hairstyle setting module 140, so that the adjustment mechanism connected to the limit comb 130 automatically drives the limit comb 130 according to the hairstyle data. 30 is used for position adjustment, and a second angular velocity sensor 80 is set.

Not only is the user operation simple and easy to use, but it can also effectively ensure that the hairstyle lengths between different head trimming areas can have a smooth transition, so as to achieve an ideal haircutting effect.

[0050] The first main controller 160 is arranged in the collection shell 20, and the size of the collection shell 20 is suitable for the user's hand to hold, so that the user can hold the collection shell 20 and perform data collection operations on his own head contour; during the movement of the collection shell 20, only the moving mechanism 30 drives the collection shell 20 to move, and the user only holds the collection shell 20 and does not participate in the operation of pushing the collection shell 20 to move, so as to ensure that the collection shell 20 can move stably during the data collection process; the number of head collection areas 101 is preferably eight, and there are three head collection areas 101 on the left and right sides of the head respectively, and two head collection areas 101 on the top of the head; the moving mechanism 30 and the collection mechanism 40 are both installed on the collection shell 20, and are both electrically connected to the first main controller 160, and the first main controller 160 controls the moving mechanism 30 to drive the collection shell 20 to move, the first main controller 160 controls the collection mechanism 40 to collect the stroke length data and the first Euler angle data, and sends the collected stroke length data and the first Euler angle data to the contour model forming module 170; the contour model forming module 170 can be optionally installed on the collection shell 20 and electrically connected to the first main controller 160, or can be optionally installed on the intelligent terminal and wirelessly connected to the first main controller 160. The contour model forming module 170 receives the stroke length data and the first Euler angle data sent by the first main controller 160, and forms a head contour point 102 for each group of stroke length data and the first Euler angle data through an algorithm or AI technology. The head contour point 102 corresponds to the position of the collection shell 20 in the current head collection area 101.

[0051] During the process of collecting data on the head contour, the head collector will perform the same collection operation on each head collection area 101 in turn. After all the collection operations are completed, the contour model forming module 170 can finally form a head contour model 10 through algorithms or AI technology. The head collection area 101 of the head contour also corresponds to the head collection area 101 of the contour model forming module 170. Each head acquisition area 101 has a starting point, which is the position where the acquisition operation of each head acquisition area 101 starts, and the starting point is generally located at the forehead of the head; the starting point is defined as the acquisition origin, and a acquisition point is formed after the acquisition shell 20 moves a unit stroke, and the acquisition mechanism 40 collects corresponding stroke length data and first Euler angle data at each acquisition point, and the unit stroke can be 1mm; the stroke length data refers to the distance moved by a certain acquisition point of the acquisition shell 20 in a single head acquisition area 101 relative to the acquisition origin of the head acquisition area 101; the first Euler angle data is also collected and recorded at the same time at the acquisition point, the origin of the coordinate system of the first Euler angle data is taken at the acquisition origin, the x-axis of the coordinate system is consistent with the left-right direction, the y-axis of the coordinate system is consistent with the front-back direction, and the z-axis of the coordinate system is consistent with the up-down direction, and the first Euler angle data refers to the angle rotated by the second acquisition mechanism 402 at the acquisition point relative to the acquisition origin.

[0052] The fully automatic hairdresser in this embodiment is provided with a moving mechanism 30 for driving the collection housing 20 to move on the head contour of the user, so that the collection mechanism 40 can accurately and stably collect the stroke length data and the first Euler angle data during the movement of the collection housing 20, thereby helping the user to get an ideal hairstyle;

[0053] Combination Fig. 9 , Fig.11 , Fig.12 , Fig.14 , Fig.15 , Fig.16 , Fig.17 As shown, the trimmer includes a blade 120, a second angular velocity sensor 80, a posture verification module 90 and a second main controller 150, the adjusting mechanism includes a first adjusting mechanism 50 and a second adjusting mechanism 60, the first adjusting mechanism 50, the second adjusting mechanism 60, the second angular velocity sensor 80, the posture verification module 90 and the hairstyle setting module 140 are all connected to the second main controller 150, the hairstyle data includes limit length data and limit angle data, the first adjusting mechanism 50 is used to drive the limit comb 130 to move forward and backward relative to the blade 120 according to the limit length data, and the second adjusting mechanism 60 is used to drive the limit comb 130 to adjust the angle according to the limit angle data.

[0054] Among them, the second main controller 150 is arranged in the trimmer, and the user holds and pushes the trimmer to perform mobile trimming operations when the trimmer is trimming. The limit comb 130 is arranged in front of the blade 120, and the blade 120 is used to cut hair. The limit comb 130 is used to limit the length of hair trimming. The blade 120 is connected to the fourth motor 100, and the fourth motor 100 can drive the blade 120 to perform hair cutting operations when working; the number of trimming indication areas 1402 is preferably eight, and there are three trimming indication areas 1402 on the left and right sides of the head respectively, and two trimming indication areas 1402 on the top of the head. The trimming indication areas 1402 are divided into multiple areas to facilitate users to perform trimming operations in steps and reduce the difficulty of trimming.

[0055] The number of head trimming areas is also eight, which correspond one to one with the trimming indication area 1402. The head trimming area refers to the position of the user's head corresponding to the position of the head indication area when the user trims his or her hair style. The head contour model 10 is obtained by collecting the user's head contour data by the collector and recording and saving it. The head contour model 10 is obtained by combining multiple head contour points 102, and each head contour point 102 corresponds to a first Euler angle data.

[0056] The blade 120 and the limit comb 130 are installed at the front end of the trimmer, the first adjustment mechanism 50, the second adjustment mechanism 60, the second main controller 150 and the second angular velocity sensor 80 are all arranged in the trimmer, the blade 120, the first adjustment mechanism 50, the second adjustment mechanism 60, the second angular velocity sensor 80 are all electrically connected to the second main controller 150, the hairstyle setting module 140 and the posture verification module 90 can be selectively installed on the trimmer and electrically connected to the second main controller 150, or can be selectively installed on the smart terminal and wirelessly connected to the second main controller 150, the wireless communication connection method is preferably Bluetooth connection, the hairstyle setting module 140 generates hairstyle data of each trimming indication area 1402 according to the pre-stored head contour model 10 and sends the hairstyle data to the second main controller 150, the hairstyle data is the hairstyle result expected by the user, and the second main controller 150 is connected to the second main controller 150. 150 controls the first adjusting mechanism 50 to change its action in real time according to the limit length data of the hairstyle data, so that the limit comb 130 can move forward and backward relative to the blade 120 in real time. The second main controller 150 also controls the second adjusting mechanism 60 to change its action in real time according to the limit angle data of the hairstyle data, so that the limit comb 130 can change its angle in real time. The angle refers to the angle between the limit comb 130 and the blade 120 in the left and right directions. The hairstyle data includes the limit length data and the limit angle data, so that the hairstyle of a certain head contour point 102 corresponding to the user after automatic trimming can reach the specified inclination angle, so as to have a perfect transition with the hairstyle of the adjacent head contour point 102 after automatic trimming. In addition, after the first adjusting mechanism 50 pushes the limit comb 130 to move away from the blade 120, the second adjusting mechanism 60 can also adjust the angle of the limit comb 130 in a larger range.

[0057] The second angular velocity sensor 80 is installed in the trimmer and its installation inclination angle is consistent with the inclination angle of the blade 120, so as to accurately detect the current posture of the trimmer. The second angular velocity sensor 80 is preferably a gyroscope sensor; the second main controller 150 sends the second Euler angle data detected by the second angular velocity sensor 80 to the posture verification module 90, and the posture verification module 90 compares the second Euler angle data with the corresponding pre-stored first Euler angle data of the head contour point 102. Only when the second Euler angle data is consistent with the first Euler angle data, it means that the position and posture of the trimmer are consistent with the position of the head contour point 102. At this time, the trimmer can perform trimming operations. Otherwise, the posture verification module 90 will prompt and guide the user to adjust the posture of the trimmer, such as prompting the user to move the head or tail of the trimmer up or down.

[0058] For another example, when the head trimming area does not correspond to the trimming indication area 1402, such as requiring to trim the trimming indication area 1402 on the left ear, but the trimmer is in the posture of trimming the right ear, the second Euler angle data of the current user actually holding the trimmer is transmitted to the posture detection module via wireless Bluetooth. The posture detection module will guide the user to adjust to the best posture of the trimmer, specifically the rotation direction, the upward or downward tilt of the blade 120 and other prompts.

[0059] When the trimmer is trimming the user's hairstyle, the same trimming operation will be performed on each head trimming area in turn. During the trimming process, the limit comb 130 adjusts its position in real time according to the hairstyle data. When all the head trimming areas are trimmed, the ideal hairstyle set by the hairstyle setting module 140 can be obtained. The pre-stored head contour model 10 can be the head contour model 10 of multiple users. When performing the trimming work, the selected head contour model 10 must be the current user's own head contour model 10.

[0060] In the fully automatic hair trimmer of the present embodiment, the hairstyle data of each trimming indication area 1402 is set in the hairstyle setting module 140, so that the first adjustment mechanism 50 and the second adjustment mechanism 60 connected to the limit comb 130 automatically drive the limit comb 130 to move forward and backward and adjust the angle according to the hairstyle data, and a second angular velocity sensor 80 is provided to detect the second Euler angle data of the head trimming area and compare the second Euler angle data with the first Euler angle data of the trimming indication area 1402 of the head contour model 10, so as to ensure that the trimmer starts the trimming work normally only when the second Euler angle data is consistent with the first Euler angle data, thereby ensuring that the hairstyle trimming effect achieved by the automatic adjustment of the limit comb 130 during trimming can be consistent with the hairstyle requirement set by the user.

[0061] The fully automatic hair trimmer in this embodiment is provided with a moving mechanism 30 for driving the collection housing 20 to move on the head contour of the user, so that the collection mechanism 40 can accurately and stably collect the stroke length data and the first Euler angle data during the movement of the collection housing 20, and the contour model forming module 170 processes all the collected stroke length data and the first Euler angle data and simulates to form a head contour model 10. The head collector can accurately simulate the user's head contour data by simultaneously collecting the stroke length data and the first Euler angle data, thereby helping the user to cut an ideal hairstyle; the hairstyle data of each trimming indication area 1402 is set in the hairstyle setting module 140, so that the first adjustment mechanism connected to the limit comb 130 can be adjusted. The mechanism 50 and the second adjustment mechanism 60 automatically drive the limit comb 130 to move forward and backward and adjust the angle according to the hairstyle data, and a second angular velocity sensor 80 is provided to detect the second Euler angle data of the head trimming area and compare the second Euler angle data with the first Euler angle data of the trimming indication area 1402 of the head contour model 10, so as to ensure that the trimmer starts the trimming work normally only when the second Euler angle data is consistent with the first Euler angle data, thereby ensuring that the hairstyle trimming effect achieved by the automatic adjustment of the limit comb 130 during trimming is consistent with the hairstyle requirement set by the user. Not only is the operation simple and easy for users to use, but it can also effectively ensure that the hairstyle lengths between different head trimming areas can have a smooth transition, so as to achieve an ideal haircutting effect.

[0062] Optionally, combined Figure 1 , Figure 2 , Fig.14 As shown, it also includes a self-starting mechanism 70 for controlling the moving mechanism 30 to start moving, the self-starting mechanism 70 includes a first direction detection switch 701 and a second direction detection switch 702 arranged at the front and rear ends of the collection shell 20, the moving mechanism 30 includes a third motor 301, a front collection wheel 302 and a rear collection wheel 303, the third motor 301 is arranged in the collection shell 20, the front collection wheel 302 and the rear collection wheel 303 are respectively connected to the bottom of the collection shell 20, the first direction detection switch 701, the second direction detection switch 702 and the third motor 301 are all connected to the first main controller 160, and the first main controller 160 automatically controls the third motor 301 to drive the rear collection wheel 303 to rotate or the front collection wheel 302 to rotate according to the detection signal of the first direction detection switch 701 or the detection signal of the second direction detection switch 702.

[0063] The front and rear ends of the collection housing 20 are respectively provided with a first direction detection switch 701 and a second direction detection switch 702. Through the level change of the first direction detection switch 701 and the second direction detection switch 702, it can be detected which of the front and rear ends of the collection housing 20 passes through the starting point of the head collection area 101 first. The detection signal refers to the level change, and the collection housing 20 is automatically controlled to move backward from the starting point in the head collection area 101 according to the detection result. When the first direction detection switch 701 or the second direction detection switch 702 does not detect the detection signal, the first main controller 160 In the sleep state, when the first direction detection switch 701 or the second direction detection switch 702 detects a detection signal, the first main controller 160 is awakened and enters the working state; specifically, when the level of the first direction detection switch 701 changes, it means that the front end of the collection shell 20 has passed the starting point first, and at this time, the main control board automatically controls the third motor 301 to drive the rear collection wheel 303 to rotate; conversely, when the level of the second direction detection switch 702 changes, it means that the rear end of the collection shell 20 has passed the starting point first, and at this time, the main control board automatically controls the third motor 301 to drive the front collection wheel 302 to rotate.

[0064] In this embodiment, a self-starting mechanism 70 that automatically controls the operation of the third motor 301 is added, and the first direction detection switch 701 and the second direction detection switch 702 of the self-starting mechanism 70 are respectively installed at the front and rear ends of the collection shell 20, which simplifies the use of the user, so that the user can randomly align the front end or the rear end of the collection shell 20 with the starting point when using it, which plays a fool-proof role, has a high degree of intelligence, and can also automatically start the third motor 301 through the received detection signal, so that the front collection wheel 302 or the rear collection wheel 303 has power, so that the collection shell 20 can continue to move normally in the head collection area 101; in addition, the collection wheel that passes the starting point later is always used as the driving wheel to push the collection shell 20 to move, which makes the drive more labor-saving and helps to extend the service life of the third motor 301; in addition, the collection wheel that passes the starting point first can also be used as the driving wheel to push the collection shell 20 to move, and the specific principle and structure are similar, which will not be repeated here.

[0065] The front collecting wheels 302 and the rear collecting wheels 303 are respectively connected to the front and rear sides of the bottom of the collecting shell 20. The collecting shell 20 can move forward and backward on the head contour by rotating the front collecting wheels 302 and the rear collecting wheels 303. The structure is simple and the movement is stable. The number of the front collecting wheels 302 and the number of the rear collecting wheels 303 are preferably two, and the shape and size of each collecting wheel are consistent. The two front collecting wheels 302 are symmetrically installed on the left and right sides of the front side of the collecting shell 20, and the two rear collecting wheels 303 are symmetrically installed on the left and right sides of the rear side of the collecting shell 20, so that the collecting shell 20 is not easy to tip over during the movement, thereby ensuring the accuracy of the collected data. The third motor 301 only drives the front collecting wheels 302 or the rear collecting wheels 303 as the active wheels to rotate. For example, when the third motor 301 drives the front collecting wheels 302 to rotate, the front collecting wheels 302 The collecting wheel 302 is the driving wheel, and the rear collecting wheel 303 is the driven wheel. When the front collecting wheel 302 rotates, the rear collecting wheel 303 will rotate along with the rotation of the front collecting wheel 302. Conversely, when the third motor 301 drives the rear collecting wheel 303 to rotate, the rear collecting wheel 303 is the driving wheel, and the front collecting wheel 302 is the driven wheel. When the rear collecting wheel 303 rotates, the front collecting wheel 302 will rotate along with the rotation of the rear collecting wheel 303. This structure in which the third motor 301 selectively drives the front collecting wheel 302 and the rear collecting wheel 303 ensures that there is no speed difference between the front collecting wheel 302 and the rear collecting wheel 303, thereby ensuring that the front collecting wheel 302 and the rear collecting wheel 303 can rotate synchronously, thereby ensuring that the collecting shell 20 can move normally relative to the head contour. This structure is simple, reliable, and easy to process and implement.

[0066] Optionally, combined Figure 1 , Figure 3 , Fig.14 As shown, the mobile mechanism 30 also includes a power distribution wheel 304, a reduction gear box, a first belt 306 and a second belt 307. The third motor 301 is connected to the power distribution wheel 304 through the reduction gear box, the front collection wheel 302 is connected to the power distribution wheel 304 through the first belt 306, and the rear collection wheel 303 is connected to the power distribution wheel 304 through the second belt 307.

[0067] Among them, a reduction gear box is connected to the third motor 301 to reduce the rotation speed of the third motor 301, so that the output torque is larger, thereby ensuring that the power distribution wheel 304 can smoothly drive the front collection wheel 302 or the rear collection wheel 303 to rotate; the rotation speed of the third motor 301 is constant, and the rotation speed after the speed change processing of the reduction gear box is also constant, so that in the process of moving the collection shell 20, only the rotation of the collection wheel drives the collection shell 20 to move, and the user only holds the collection shell 20 and does not participate in the operation of pushing the collection shell 20 to move, so as to ensure that the collection shell 20 can move at a uniform speed in each head collection area 101 during the data collection process, thereby avoiding the situation where the data collection times are insufficient due to the collection shell 20 moving too fast or the data collection times are too many due to the moving speed being too slow, so that the collection mechanism 40 can accurately collect the stroke length data and the first Euler angle data at a stable collection frequency during the movement of the collection shell 20. The power distribution wheel 304 drives the front collection wheel 302 and the rear collection wheel 303 to rotate respectively through the first belt 306 and the second belt 307, and the power distribution wheel 304 can only drive one of the front collection wheel 302 and the rear collection wheel 303 to actively rotate at a time, so that there is no speed difference between the front collection wheel 302 and the rear collection wheel 303, ensuring that the front collection wheel 302 and the rear collection wheel 303 can rotate synchronously; specifically, when the level of the first direction detection switch 701 changes, it means that the front end of the collection housing 20 has passed the starting point first, and at this time the main control The control board automatically controls the third motor 301 to rotate in the reverse direction, and the third motor 301 drives the power distribution wheel 304 to rotate in the reverse direction. The power distribution wheel 304 rotating in the reverse direction drives the rear collection wheel 303 to rotate through the second belt 307. Conversely, when the level of the second direction detection switch 702 changes, it means that the rear end of the collection shell 20 has passed the starting point first. At this time, the main control board automatically controls the third motor 301 to rotate in the forward direction, and the third motor 301 drives the power distribution wheel 304 to rotate in the forward direction. The power distribution wheel 304 rotating in the forward direction drives the front collection wheel 302 to rotate through the first belt 306.

[0068] Optionally, combined Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, the front-row collecting wheel 302 is coaxially connected to the front-row connecting wheel 308 which is transmission-connected to the first belt 306, and the rear-row collecting wheel 303 is coaxially connected to the rear-row connecting wheel 309 which is transmission-connected to the second belt 307. A forward locking component 310 is provided between the front-row connecting wheel 308 and the front-row collecting wheel 302, and a reverse locking component 311 is provided between the rear-row connecting wheel 309 and the rear-row collecting wheel 303.

[0069] When the power distribution wheel 304 rotates forward, the front connecting wheel 308 is driven to rotate forward through the first belt 306, and the front collecting wheel 302 is locked with the front connecting wheel 308 through the forward locking component 310, so that when the front connecting wheel 308 rotates, the front collecting wheel 302 is also driven to rotate, and when the power distribution wheel 304 rotates forward, the reverse locking component 311 will not lock the rear connecting wheel 309 with the rear collecting wheel 303, so the power distribution wheel 304 drives the rear connecting wheel 309 to rotate through the second belt 307, and the rotation of the rear connecting wheel 309 will not drive the rear collecting wheel 303 to rotate, that is, at this time, the front collecting wheel 302 is the driving wheel, and the rear collecting wheel 303 is the driven wheel; On the contrary, when the power distribution wheel 304 rotates in the opposite direction, the rear connecting wheel 309 is driven to rotate in the opposite direction through the second belt 307, and the rear collecting wheel 303 is locked with the rear connecting wheel 309 through the reverse locking component 311, so that when the rear connecting wheel 309 rotates, the rear collecting wheel 303 is also driven to rotate, and when the power distribution wheel 304 rotates in the opposite direction, the forward locking component 310 will not lock the front connecting wheel 308 and the front collecting wheel 302 with each other, so the power distribution wheel 304 drives the front connecting wheel 308 to rotate through the first belt 306, and the rotation of the front connecting wheel 308 will not drive the front collecting wheel 302 to rotate, that is, at this time the rear collecting wheel 303 is the driving wheel, and the front collecting wheel 302 is the driven wheel.

[0070] In this embodiment, a forward locking component 310 and a reverse locking component 311 with opposite locking directions are respectively provided on the front collection wheel 302 and the rear collection wheel 303, so that the position switching of the driving wheel and the driven wheel can be achieved by switching the rotation direction of the power distribution wheel 304, and the structure is simple and reliable.

[0071] Optionally, combined Figure 1 , Figure 3 , Figure 4 , Figure 5As shown, the positive locking assembly 310 includes a first locking block 3101 and a first locking pin 3102 that cooperate with each other. The first locking block 3101 and the first locking pin 3102 are respectively arranged on the front connecting wheel 308 and the front collecting wheel 302. A first return spring 3103 is arranged between the first locking block 3101 and the front connecting wheel 308. The first locking block 3101 is provided with a first locking portion 31011 and a first yielding guide portion 31012. When the front connecting wheel 308 rotates forward, the first locking portion 31011 and the first locking pin 3102 abut against each other to achieve mutual locking of the front connecting wheel 308 and the front collecting wheel 302. When the front connecting wheel 308 rotates reversely, the first yielding guide portion 31012 can move relative to the first locking pin 3102. The reverse locking assembly 311 comprises a second locking block 3111 and a second locking pin 3112 which cooperate with each other, the second locking block 3111 and the second locking pin 3112 are respectively arranged on the rear connecting wheel 309 and the rear collecting wheel 303, a second return spring 3113 is arranged between the second locking block 3111 and the rear connecting wheel 309, the second locking block 3111 is provided with a second locking portion 31111 and a second yielding guide portion 31112, when the rear connecting wheel 309 rotates in the reverse direction, the second locking portion 31111 and the second locking pin 3112 abut against each other to realize mutual locking of the rear connecting wheel 309 and the rear collecting wheel 303, and when the rear connecting wheel 309 rotates forwardly, the second yielding guide portion 31112 can move relative to the second locking pin 3112.

[0072] The first locking block 3101 and the second locking block 3111 have the same structure, the second locking pin 3112 and the first locking pin 3102 have the same structure, the first locking block 3101 and the second locking block 3111 are symmetrically arranged, and the structure of the first locking block 3101 and the second locking block 3111 is a right-angled trapezoidal structure, which has a simple structure and a reliable locking function; the first return spring 3103 pushes the first locking block 3101 to extend outward, and the first locking block 3101 The first locking portion 31011 is located at the right angle side of the right-angled trapezoidal structure so as to cooperate with the first locking pin 3102. The first yielding guide portion 31012 is located at the hypotenuse of the right-angled trapezoidal structure. When the first locking block 3101 rotates until the first yielding guide portion 31012 cooperates with the first locking pin 3102, the first locking pin 3102 squeezes the first yielding guide portion 31012 so that the first locking block 3101 moves to compress the first return spring 3103 until the first locking pin 310 After the first locking block 3101 is separated from the first yielding guide portion 31012, the first locking block 3101 is restored to its original extended length under the action of the reset force of the first reset spring 3103. Similarly, the second reset spring 3113 pushes the second locking block 3111 to extend outward, and the second locking portion 31111 of the second locking block 3111 is located at the right angle side of the right-angled trapezoidal structure to cooperate with the second locking pin 3112. The second yielding guide portion 31112 is located at the oblique side of the right-angled trapezoidal structure. When the second locking block 3111 rotates to the point where the second yield guide portion 31112 cooperates with the second locking pin 3112, the second locking pin 3112 squeezes the second yield guide portion 31112 so that the second locking block 3111 moves and compresses the second return spring 3113, until the second locking pin 3112 and the second yield guide portion 31112 are disengaged from each other, and the second locking block 3111 recovers to its original extended length under the action of the return force of the second return spring 3113.

[0073] Optionally, combined Figure 1 , Figure 6 As shown, the front collecting wheel 302 and the rear collecting wheel 303 are both connected to a first connecting rod 312 , and a third return spring 305 is provided between the first connecting rod 312 and the collecting housing 20 .

[0074] Among them, the front collection wheel 302 and the rear collection wheel 303 are connected to the collection shell 20 through the first connecting rod 312, and a third return spring 305 is provided, so that the first connecting rod 312 can move up and down relative to the collection shell 20, so as to realize that the front collection wheel 302 and the rear collection wheel 303 can move up and down relative to the collection shell 20, which helps to increase the angle change range of the collection bracket 4021 in the second collection mechanism 402 to adapt to the use of more shapes of head contours.

[0075] Optionally, combined Figure 1 , Figure 6 As shown, the first acquisition mechanism 401 includes a acquisition wheel, a connecting rod and a third photoelectric encoder disk 4011 arranged on the side of the acquisition wheel, a plurality of encoding disk holes 40111 are arranged at intervals in the circumferential direction of the third photoelectric encoder disk 4011, and a third photoelectric sensor 4012 for sensing the encoding disk holes 40111 is installed on the connecting rod.

[0076] The third photoelectric encoder 4011 is used in conjunction with the third photoelectric sensor 4012 to detect the rotation speed and number of revolutions of the collection wheel, so that the first main controller 160 calculates the travel length of the collection wheel according to the rotation speed and number of revolutions of the collection wheel. When the third photoelectric sensor 4012 coincides with the encoding disc hole 40111, a high level is obtained, and when the third photoelectric sensor 4012 does not coincide with the encoding disc hole 40111, a low level is obtained. Preferably, one or more of the front row collection wheel 302 and / or the rear row collection wheel 303 are used as the collection wheel. Each time the high level of the third photoelectric sensor 4012 changes, the travel distance of the collection wheel is a unit travel. For example, if the number of the encoding disc holes 40111 is 10, the length of a unit travel is the circumference of the collection wheel / 10. In this embodiment, the third photoelectric encoder 4011 is provided on the collection wheel, and the collection of the travel length data of the collection housing 20 is realized by mutual induction between the encoding disc hole 40111 and the third photoelectric sensor 4012 during the rotation of the collection wheel, so as to ensure the reliability and accuracy of the collection of the travel length data.

[0077] Optionally, combined Figure 1 , Figure 2 , Figure 7 As shown, the second acquisition mechanism 402 includes a acquisition bracket 4021 and a first angular velocity sensor 4022 for detecting the first Euler angle data, the first angular velocity sensor 4022 is installed in the acquisition bracket 4021, the acquisition bracket 4021 is vertically connected to the front and rear directions of the acquisition shell 20, and acquisition blocks 40211 are provided at the left and right ends of the acquisition bracket 4021, and the two acquisition blocks 40211 are always in contact with the head contour during the movement of the acquisition shell 20; a second connecting rod 4023 is connected between the acquisition bracket 4021 and the acquisition shell 20, the second connecting rod 4023 is movably connected to the acquisition shell 20 up and down, and the second connecting rod 4023 is rotatably connected to the acquisition bracket 4021.

[0078] Among them, the first angular velocity sensor 4022 is installed at the center of the collection bracket 4021, and a fourth reset spring 4024 is provided between the second connecting rod 4023 and the collection shell 20 to enable the collection bracket 4021 to move up and down relative to the collection shell 20. A rotating shaft 4025 is provided between the second connecting rod 4023 and the collection bracket 4021 to enable the collection bracket 4021 to swing left and right around the front and back directions of the collection shell 20. During the movement of the collection bracket 4021, the first angular velocity sensor 4022 is used to detect and obtain the first Euler angle data every unit stroke. The collector moves During the movement, the acquisition bracket 4021 will change its position along the head contour, and the first Euler angle data detected by the first angular velocity sensor 4022 will also change simultaneously; the first angular velocity sensor 4022 is preferably a gyroscope sensor, which also includes an acceleration sensor, wherein the first angular velocity sensor 4022 is used to detect the first Euler angle data of the acquisition bracket 4021 during the movement on the head contour, so as to prompt the user to keep the grip horizontally or vertically, and the acceleration sensor can be used to detect whether the user forcibly applies force, so as to avoid the collection shell 20 being pushed forward too fast or too slow.

[0079] The contour model forming module 170 synchronously processes the stroke length data collected by the first acquisition mechanism 401 and the first Euler angle data collected by the second acquisition mechanism 402 through an algorithm or AI technology to form a head contour point 102; for example, the circumference of the acquisition wheel is set to 36 mm, and the number of the encoding disk holes 40111 on the acquisition wheel is set to 36. In this way, each time the high level of the third photoelectric sensor 4012 changes once, the acquisition wheel rotates about 10°, and the rotation change of 10° means that the acquisition wheel travels 1mm. At this time, the first main controller 160 records and saves the first Euler angle data of each 1mm stroke length, so that the corresponding stroke length data and the first Euler angle data can be detected simultaneously for each 1mm stroke position, and in the same head acquisition area 101, the current position can be inferred from the known first Euler angle data.

[0080] In this embodiment, a collection bracket 4021 is provided which can be moved up and down and adjusted left and right relative to the collection shell 20, and a first angular velocity sensor 4022 which can detect first Euler angle data is provided in the collection bracket 4021. The structure is simple and reliable, and can ensure that the collection bracket 4021 is always in contact with the head contour as the head contour changes, thereby effectively ensuring that the first Euler angle data detected by the first angular velocity sensor 4022 is consistent with the transformed angle of the head contour, so as to ensure that an accurate head contour model 10 is finally formed.

[0081] Optionally, combined Figure 1 , Figure 8 , Fig. 9 , Fig.10 As shown, the first Euler angle data includes a yaw angle, a pitch angle and a roll angle, the yaw angle is used to detect the position of the acquisition shell 20 in the head acquisition area 101, the pitch angle is used to detect the straightening position of the head contour, and the roll angle and the stroke length data form the head contour point 102.

[0082] Among them, the pitch angle is the angle of rotation around the x-axis of the coordinate system, the roll angle is the angle of rotation around the y-axis of the coordinate system, and the yaw angle is the angle of rotation around the z-axis of the coordinate system; when the collector starts to move backward from the starting point of a head collection area 101 to perform a collection operation, the change in the yaw angle can be used to determine whether the collector has moved to the back of the head contour, thereby determining whether the collector has completed the head collection area 101, which can ensure that the collector has completely collected data in each head collection area 101, thereby improving the accuracy of head contour data collection; during the movement and collection of the collector, the user's head is generally required to be straight, that is, the forehead of the head should be roughly facing the front. If the user's head is lowered or raised, the change in the pitch angle can be used to prompt the user to straighten the head contour, thereby ensuring the accuracy of data collection and simplifying the simulation method of the head contour model 10; the change in the roll angle is consistent with the change in the left and right angles of the collection bracket 4021, and only the roll angle data and the corresponding stroke length data are processed together to form the data of the head contour point 102, and the calculation method is simple and accurate.

[0083] Optionally, combined Fig.11 , Fig.14 , Fig. 9 As shown, the hairstyle setting module 140 includes a length modification module 1401 , and the length modification module 1401 is used for the user to adjust the hairstyle data of the trimming indication area 1402 .

[0084] Among them, the hairstyle setting module 140 will provide a hairstyle model for user reference based on the head contour model 10. The user can adjust the length of the hairstyle model provided for reference through the length modification module 1401 to generate an adjusted hairstyle model. The adjustment method includes lengthening the hair length, shortening the hair length or not modifying the hair length. For example, as shown in the figure, the user clicks to modify the hair length of a certain modification indication area in the hairstyle setting module 140. The hair length recommended by the hairstyle setting module 140 is such as curve M. After clicking to modify, curve N will be generated. After the modification is confirmed, the hairstyle setting module 140 will first make an accumulated difference to the original length to form a new hairstyle data and send it to the main controller of the trimmer via wireless Bluetooth. The trimmer adjusts the length and angle of the limit according to the hairstyle data.

[0085] In this embodiment, a length modification model is set so that the hairstyle setting module 140 can provide the user with a reference hairstyle or fine-tune the reference hairstyle according to the head contour data, thereby making the selection and design of the hairstyle more intelligent and meeting the user's higher usage requirements.

[0086] Optionally, combined Fig.11 , Fig.12 , Fig.14 As shown, the first adjustment mechanism 50 includes a first motor 501 and a length adjustment component 502. The two ends of the length adjustment component 502 are respectively connected to the first motor 501 and the limit comb 130. The first motor 501 drives the length adjustment component 502 to push the limit comb 130 to move forward and backward.

[0087] Among them, the length adjustment component 502 is connected to the center position of the lower end of the limit comb 130 to ensure that it does not interfere with the hair trimming operation of the blade 120 located above. The forward and reverse rotation of the first motor 501 can drive the length adjustment component 502 to extend and retract, so that the first adjustment mechanism 50 pushes the limit comb 130 to move forward and backward; the first motor 501 is electrically connected to the second main controller 150, and the second main controller 150 drives the first motor 501 to perform corresponding work according to the limit length data, so as to achieve the purpose of moving the limit comb 130 relative to the blade 120.

[0088] Optionally, combined Fig.11 , Fig.12 As shown, the length adjustment component 502 includes an adjusting screw 5021, an adjusting nut and a positioning support rod 5022, one end of the positioning support rod 5022 is connected to the adjusting nut, and the other end is connected to the limiting comb 130, the adjusting screw 5021 is connected to the first motor 501, and the adjusting nut cooperates with the adjusting screw 5021.

[0089] Among them, one end of the positioning support rod 5022 is fixedly connected to the outer wall of the adjusting nut, and the other end is fixedly connected to the middle part of the lower end of the limiting comb 130; the end of the adjusting screw 5021 connected to the adjusting nut is provided with an external thread of a certain length, and the external thread is matched with the adjusting nut; a first reduction gear box 5025 is provided between the first motor 501 and the adjusting screw 5021 to reduce the rotation speed of the first motor 501 so that the output torque is larger to ensure that the first motor 501 drives the adjusting screw 5021 to rotate when working. During the rotation of the adjusting screw 5021, the adjusting nut can move in the front and rear directions relative to the adjusting screw 5021, thereby realizing the change of the position of the limiting comb 130.

[0090] In this embodiment, a structure in which an adjusting screw 5021 and an adjusting nut cooperate is adopted so that the first motor 501 can drive the limit comb 130 to move by moving the positioning support rod 5022 forward and backward. The structure is simple, and the forward and backward position change of the limit comb 130 is stable and reliable.

[0099] The reversing gearbox 6021 also includes a deceleration function to reduce the rotation speed of the second motor 601, so that the output torque is greater, so as to ensure that the second motor 601 drives the left adjustment component 6022 and the right adjustment component 6023 to move when working; the reversing gearbox 6021 is composed of three bevel gears, one of which is fixedly connected to the motor shaft of the second motor 601, and the other two bevel gears are respectively located on the left and right sides of the bevel gear and are respectively meshed with the bevel gear, and the bevel gears located on the left and right sides are respectively meshed with the left adjustment component 60 22 and the right adjusting component 6023 are fixedly connected, so that when the second motor 601 rotates, the left adjusting component 6022 and the right adjusting component 6023 can move in opposite directions respectively; the left adjusting component 6022 and the right adjusting component 6023 are respectively connected to the left and right sides of the limiting comb 130, when the left adjusting component 6022 pushes the left end of the limiting comb 130 forward, the right adjusting component 6023 pulls the right end of the limiting comb 130 backward, thereby changing the angle between the limiting comb 130 and the blade 120 in the left and right directions.

[0100] In this embodiment, two left and right adjustment components are used to drive the limiting comb 130 to change its angle, so that the angle adjustment of the limiting comb 130 is more stable and reliable, and can also play a supporting role on both sides of the limiting comb 130, so that when the trimmer is trimming, the position of the limiting comb 130 will not be changed by external force, and the extended length and tilt angle of the limiting comb 130 can be kept accurate to achieve an ideal haircutting effect.

When the left connecting rod 60221 and / or the right connecting rod 60231 rotates, the second photoelectric encoder 603 can be driven to rotate synchronously. The second photoelectric sensor 604 can be arranged on the trimmer housing or on the reversing gear box 6021. The position of the second photoelectric sensor 604 is fixed and unchanged.

Or the rotation speed and number of revolutions of the right connecting rod 60231, so that the second main controller 150 calculates the distance that the left rack moves in the front-to-back direction relative to the left gear 60223 and / or the distance that the right rack moves in the front-to-back direction relative to the right gear 60233 according to the rotation speed and number of revolutions of the left connecting rod 60221 and / or the right connecting rod 60231; the second photoelectric encoder disk 603 is provided with a plurality of holes, and a high level is obtained when the second photoelectric sensor 604 coincides with the hole, and a low level is obtained when the second photoelectric sensor 604 does not coincide with the hole.

[0105] In this embodiment, a second photoelectric encoder 603 is provided on the left connecting rod 60221 and / or the right connecting rod 60231, and during the rotation of the connecting rod and / or the right connecting rod 60231, the second photoelectric encoder 603 and the second photoelectric sensor 604 are inductively coupled to each other to control the angle change of the limit comb 130 according to the received limit angle data, so as to ensure the reliability and accuracy of the angle adjustment position of the limit comb 130; the left support arm push rod 60222 and the right support arm push rod 60232 are made of metal to ensure the supporting strength.

[0106] Preferably, combined Fig.11 , Fig.12 , Fig.13 As shown, the ratio between the length distance of the limit comb 130 extended or retracted and the angle between the limit comb 130 and the blade 120 in the left and right directions is 1:3. The ratio is set to ensure that the limit comb 130 will not interfere with the blade 120 when it rotates to the maximum angle in the left and right directions relative to the blade 120. For example, the first motor 501 is transmitted to the adjusting screw 5021 through the first reduction gear box 5025, and the first photoelectric sensor 5024 detects that the adjusting screw 5021 rotates 1 circle, and is set to 1 circle equal to 1 mm. Then, the current position of the position points A, B, and C is 1 mm away from the starting position. The second motor 601 is transmitted to the left connecting rod 60221 and the right connecting rod 60231 through the reversing gear box 6021, and the second photoelectric sensor The sensor 604 detects that the left connecting rod 60221 and the right connecting rod 60231 rotate 1 circle, and is set to 1 circle equal to 1mm. At this time, the distance between the current position of the position point A and the starting position is -1mm, and the distance between the current position of the position point C and the starting position is +1mm. The angle of the limit comb 130 changes by about 3° for every 1mm change in the extended length of the limit comb 130. Therefore, this ratio is set to 1:3. In this way, if the angle of the limit comb 130 needs to be adjusted by 1°, it is only necessary to push the limit comb 130 forward by 0.33mm, and at the same time, the left support arm push rod 60222 and the right support arm push rod 60232 also move 0.33mm in opposite directions. The above-mentioned position points A, B, and C are three points located at the left, middle, and right positions of the limit comb 130, respectively.
