Description

TECHNICAL FIELD

[0001] The present application belongs to the field of nursing automation, and particularly relates to an automatic haircut method and a wearable haircut device. BACKGROUND

[0002] Haircut is a regular personal care, which is difficult to be completed by oneself and needs more external human intervention, because, on one hand, the head of a person cannot be directly observed by his own eyes, leading to difficulty in self haircut; on the other hand, the shape of the head of a person is not a regular shape, and haircut is achieved by cutting with a blade, so if a person forcibly cuts his own hair, he is easy to be injured, or it is difficult to cut the hair well along the head, but external human intervention means that the economic cost of haircut rises, and the site of haircut is limited.

[0003] At present, various automatic or semi-automatic haircut devices appear in the market, which include a mechanical arm or a complex linkage mechanism, a haircut blade is arranged at the end of the mechanical arm or the complex linkage mechanism, in haircut, a preset haircut path is set, and then the mechanical arm or the linkage mechanism is controlled to move the haircut blade along the haircut path once or multiple times, so as to perform the haircut operation (similar to peeling a pear).

[0004] However, the above haircut device has high hardware cost due to the existence and control of the mechanical arm or the complex linkage mechanism, and the mechanical arm or the linkage mechanism not only has a large size, but also occupies more space when moving under control, so the above haircut device must have a fixed site with a large accommodation space as a prerequisite for implementation when implemented, therefore, although the automatic haircut device is realized in form, the defects of the related economic cost and site requirement have not been well solved, which seriously hinders the commercialization of the product. SUMMARY

[0005] In view of the defects of the prior art, the present application provides an automatic haircut method and a wearable haircut device, which are used in cooperation to greatly reduce the physical space occupied by the device as a whole, are flexible to use, and can meet the general haircut visual requirement.

[0006] To achieve the above object, the present application provides the following technical scheme: An automatic haircut method for cutting the hair of a target head, taking the imaginary arc line extending along the target head with the two ears as the two ends as the head latitude line, and taking the imaginary arc line extending along the target head and perpendicular to the head latitude line as the head longitude line, comprising the following steps: An automatic hair cutting method for cutting hair of a target head, characterized in that a virtual arc extending along the target head and taking the two ears as the two ends is taken as a head latitude line, a virtual arc extending along the target head and being perpendicular to the head latitude line is taken as a head longitude line, and the method comprises the following steps: A hair cutting track parallel to the head latitude line is provided, and a hair cutting implement is arranged on the hair cutting track to cut the hair of the target head; The hair cutting track is swung along the head longitude line to assist the hair cutting implement in cutting the hair along the head longitude line; The hair cutting track is moved towards or away from the shoulder on which the target head is located to assist the hair cutting implement in moving to cut the hair;

[0007] Preferably, a cutting knife set is arranged on the hair cutting implement to elastically abut against the target head, and the cutting knife set is used to cut the hair of the target head and is adapted to move relative to the hair cutting track. Further, an air suction fan is arranged on the hair cutting implement to suck the cut hair away from the target head.

[0008] Still further, a closed suction channel is arranged between the air suction fan and the cutting knife set.

[0009] Further, a fine-tuning comb plate is arranged between the cutting knife set and the target head, the fine-tuning comb plate has comb teeth for passing through the hair, and the fine-tuning comb plate is adapted to move towards the hair cutting track relative to the cutting knife set, when the fine-tuning comb plate is moved to have different distances from the cutting knife set, the cutting knife set cuts the hair to different lengths. Preferably, the hair cutting implement is adapted to rotate along the extension direction of the hair cutting implement.

[0010] Further, in step S2, the hair cutting track is swung in a moving manner in a step-by-step path, and the hair cutting implement is adapted to rotate at different angles based on the position of the target head corresponding to the hair cutting implement.

[0011] A wearable hair cutting device, comprising a wearable assembly, the wearable assembly comprising a body binding belt, a pair of shoulder base plates, and a fixing plate body, a lifting assembly comprising a pair of lifting lead screws corresponding fixedly arranged on the shoulder base plates, the lifting lead screws comprising a lead screw base, a lifting motor, a lifting lead screw, and a lifting slider, a track assembly comprising a swing motor and a hair cutting track, and a hair cutting implement arranged on the hair cutting track through a coupling unit, the wearable assembly being coupled with the hair cutting track, the wearable assembly comprising the body binding belt and the fixing plate body, and the body binding belt being used to be worn by a human body.

[0012] Preferably, the body-binding strap includes a front chest strap and a pair of armpit straps. The front chest strap corresponds to the front of the human body, and its two ends are respectively located near a pair of armpits. The armpit straps are connected to the two ends of the front chest strap and encircle the armpits of the human body. The shoulder base plate encircles the shoulders of the human body and is connected to the armpit straps at the front of the human body. The pair of shoulder base plates are respectively connected to the two ends of the fixed plate at the rear of the human body. The pair of armpit straps converge at the rear of the human body and are fixed to the fixed plate.

[0013] Preferably, the coupling unit includes a coupling base shell, and a drive assembly and a rotation assembly both disposed on the coupling base shell. The drive assembly includes a drive motor and a drive gear disposed on the output shaft of the drive motor. The rotation assembly includes a rotation motor and a rotation bracket disposed on the output shaft of the rotation motor. The outer surface of the haircutting track is a rack surface extending along the latitude line of the head. The drive gear meshes with the rack surface. The rotation bracket is connected to the haircutting execution mechanism. Compared with the prior art, the beneficial effects of the present invention are: 1. The automatic haircutting method of the present invention first sets up a haircutting track parallel to the latitude line of the head, and sets up a haircutting actuator that can move along the haircutting track. The haircutting actuator is used to cut the hair of the target head. Then, the haircutting track is set to swing along the meridian line of the head. Then, the haircutting track is moved vertically. Through the swinging action of the haircutting track, the haircutting actuator is driven to swing along the meridian line of the head corresponding to the target head. The haircutting actuator realizes that it corresponds to the target head on the latitude line of the head, thereby realizing haircutting at any position of the target head. Moreover, the method can be realized without the need for a relatively complex control method and linkage device. Therefore, the present invention can greatly reduce the physical space occupied by the overall device, and is flexible in use, which can meet the general haircutting appearance requirements.

[0014] 2. Because in this invention, a set of cutting blades is provided on the hair-cutting actuator that elastically abuts against the target head. The cutting blades are used to cut the hair on the target head, and the cutting blades can adaptively move relative to the hair-cutting track. Therefore, this invention can always keep the cutting blades close to the target head through the adaptive movement of the cutting blades, thereby enabling more accurate haircutting.

[0015] 3. Because an exhaust fan is installed on the hair-cutting actuator in this invention, which is used to remove the cut hair from the target head, this invention can remove the cut hair from the target head without requiring excessive subsequent processing of the cut hair, thus providing the user with a better hair-cutting experience.

[0016] 4. Because a closed extraction channel is provided between the exhaust fan and the shearing blade assembly in this invention, the efficiency of hair removal is greatly improved by the extraction channel.

[0017] 5. Because in this invention, a fine-tuning comb plate is provided between the cutting blade assembly and the target head. The fine-tuning comb plate has comb teeth for passing through the hair. The fine-tuning comb plate can move relative to the cutting blade assembly toward the hair cutting track. When the fine-tuning comb plate moves to different distances from the cutting blade assembly, the length of hair cut by the cutting blade assembly is different. When the hair cutting actuator cuts hair on the target head, the hair passes through the comb teeth of the fine-tuning comb plate at equal lengths and is then cut by the cutting blade assembly. That is, the hair cutting length is equal to the length difference of the hair length passing through the gap between the comb teeth and the cutting blade assembly. The fine-tuning comb plate can adjust this length difference. Therefore, this invention can flexibly adjust the length of the cut hair, thereby achieving a layered representation of the head area and significantly improving the appearance of the haircut.

[0018] 6. Because in this invention, the hair-cutting track swings in a step-by-step path movement manner, and the hair-cutting actuator rotates at different angles based on the position of its corresponding target head, the cutting angle of the scissor assembly can be changed by rotation at different positions of the target head. Since the hair at different positions of the target head hangs down in significantly different ways due to gravity, the scissor assembly can always cut in the direction of hair hanging down or close to the direction of hair hanging down, thus enabling more efficient haircutting. In particular, when cutting hair in the ear area, in order to avoid cutting the auricle and to cut a better ear contour hairstyle, the actuator can rotate at multiple consecutive angles to make the hair-cutting component move strictly along the ear contour.

[0019] 7. Because the wearable hairdressing device of the present invention includes a wearable component, a lifting component, a track component, and a haircutting actuator, the wearable component is worn by a human body, the wearable component includes a body-binding strap, a pair of shoulder base plates, and a fixed plate, the lifting component includes a pair of lifting screws correspondingly fixed on the shoulder base plates, the track component includes a drive motor and a haircutting track, the haircutting actuator is set on the haircutting track through a coupling unit, the wearable component is coupled to the haircutting track, the wearable component includes a body-binding strap and a fixed plate, the body-binding strap is for being worn by a human body, and the fixed plate has threaded holes, therefore, the present invention can be directly worn by a human body, that is, a person can complete automated haircutting while walking, and the fixed plate also has the possibility of being connected to an external platform, such as a seat.

[0036] To make the technical means, creative features, objectives and effects of the present invention easier to understand, the following embodiments, in conjunction with the accompanying drawings, specifically illustrate an automatic haircutting method and wearable haircutting device of the present invention. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0037] The automatic haircutting method in this embodiment is used to cut hair on a target head. It uses an imaginary arc extending along the target head with the ears as its two ends as the head's latitude line, and an imaginary arc extending along the target head and perpendicular to the head's latitude line as the head's longitude line. The method includes the following steps: A haircutting track is set up parallel to the latitude line of the head, and a haircutting actuator is set on the haircutting track to move along the haircutting track. The haircutting actuator is used for the haircutting steps of the target head.

[0038] A set of cutting blades is installed on the hair-cutting actuator, which elastically abuts against the target head. The cutting blade set is used to cut the hair on the target head and can move adaptively relative to the hair-cutting track. Specifically, the cutting blade set consists of two stacked comb-tooth blades, similar to the blades of electric clippers. By moving the comb-tooth blades in a relatively staggered manner, the hair passing through the gaps between the comb teeth is cut. The hair-cutting actuator has two separate parts connected by a spring. The cutting blade set is set on one of the separate parts, so that the elastic force of the spring ensures that the cutting blade set is always close to the target head throughout the hair-cutting process. At the same time, the extension length of the hair-cutting actuator can be adaptively adjusted based on the change in distance between the target head and the hair-cutting track.

[0039] An exhaust fan is installed on the hair-cutting actuator to remove the cut hair from the target head. A closed extraction channel is provided between the exhaust fan and the cutting blade assembly. In this embodiment, the extraction channel passes through the spring member between the two parts of the hair-cutting actuator, that is, the spring member includes at least an elastic telescopic tube.

[0040] A fine-tuning comb plate is placed between the cutting blade assembly and the target head. The fine-tuning comb plate has comb teeth for passing through the hair. The fine-tuning comb plate can move relative to the cutting blade assembly toward the hair cutting track. When the fine-tuning comb plate moves to different distances from the cutting blade assembly, the length of hair cut by the cutting blade assembly is different. Specifically, when the hair cutting actuator cuts hair on the target head, the hair passes through the comb teeth of the fine-tuning comb plate at equal lengths and is then cut by the cutting blade assembly. That is, the hair cutting length is equal to the length difference of the hair passing through the gap between the comb teeth and the cutting blade assembly. The fine-tuning comb plate can adjust this length difference, thereby achieving layered hair cutting for the corresponding head area.

[0041] The step involves swinging the hair-cutting track along the head's meridian to assist the hair-cutting actuator in cutting hair along the head's meridian direction.

[0042] This allows the haircutting actuator to rotate along its own extension direction, the haircutting track to swing in a step-by-step path movement mode, and the haircutting actuator to rotate at different angles based on the position of the target head it corresponds to.

[0043] The haircutting track is moved toward or away from the shoulder where the target head is located, to assist the movement of the haircutting actuator in performing additional haircutting steps.

[0044] A wearable component is coupled to the hair-cutting track. The wearable component includes a body-binding strap and a fixing plate. The body-binding strap is worn by the human body, and the fixing plate has threaded holes. Specifically, the human body wears the wearable component directly, so that the hair-cutting process does not require the human body to be in a sitting position. It is only necessary to keep the potential energy of the hair-cutting track higher than the target head. The fixing plate can also be connected and fixed to an external platform through the threaded holes. In this embodiment, the energy supply can be external, such as external power supply; or it can be a power supply component set on the fixing plate. The setting method can be detachable or non-detachable. The power supply component can be a rechargeable power supply component or a non-rechargeable power supply component.

[0045] like Figure 1 and Figure 2 As shown, a wearable hair-cutting device 1000 based on the above-mentioned hair-cutting method includes a wearable component 200, a lifting component 300, a track component 400, a hair-cutting actuator 500, and a hair-cutting actuator 100.

[0046] The wearable component 200 is worn on the upper body by the human body. The wearable component 200 includes a body binding strap 210, a pair of shoulder base plates 220 and a fixing plate 230.

[0047] The body binding 210 includes a front chest binding 211 and a pair of armpit bindings 212.

[0048] The front chest strap 211 corresponds to the front chest of the human body, and its two ends are respectively located near a pair of armpits. The armpit strap 212 is connected to the two ends of the front chest strap 211, and the armpit strap 211 encircles the armpits of the human body. The shoulder base plate 220 encircles the shoulders of the human body and is connected to the armpit strap 212 at the front of the human body. The pair of shoulder base plates 220 are respectively connected to the two ends of the fixed plate 230 at the rear of the human body. The pair of armpit straps 212 converge at the rear of the human body and are fixed to the fixed plate 230. Specifically, the front chest strap 211 is a two-section split, which can be connected or unconnected by engaging the buckle 211a. The human body completes the wearing of the wearable component 200 by extending both arms into the pair of armpit straps and closing the front chest strap 211 by engaging the buckle 211a. The body binding strap 210 is elastic, so as to adapt to the upper body of the human body.

[0049] The lifting assembly 300 includes a pair of lifting screws correspondingly fixed on the shoulder base plate 220. The lifting screws include a screw base 310, a lifting motor 320, a lifting screw 330, and a lifting slider (not shown in the figure).

[0050] Specifically, the lifting screw 330 is mounted on the screw base 310, the output end of the lifting motor 320 is coupled to the lifting screw 330, and the lifting slider is movably mounted on the lifting screw 330.

[0051] Specifically, when the wearable component 200 is worn by the human body, the lifting slider has the freedom to move between the top of the target head H and the shoulder base plate 220.

[0052] like Figure 3 As shown, the track assembly 400 includes a pendulum motor 410 and a barber track 420.

[0053] Specifically, there is a pair of pendulum motors 410, which are respectively set on a pair of lifting sliders. When the lifting sliders move, they can drive the pendulum motors 410 to move. The hairdressing track 420 is a convex arc along the latitude line T1 of the head. The outer surface of the convex arc is a rack surface 420a extending along the latitude line of the head. When the pair of pendulum motors 410 rotate synchronously, they can drive the hairdressing track 420 to swing and rotate along the longitude line T2 of the head. In this embodiment, both the lifting motor 320 and the pendulum motor 410 are stepper motors. The linear distance of the lifting slider and the rotation angle of the hairdressing track 420 can be calculated according to the frequency of the input signal and the duration of the signal input.

[0054] like Figure 4 and Figure 5 As shown, the coupling unit 500 includes a coupling base shell 510, and a drive assembly 520 and a drive rotation assembly 530, both disposed on the coupling base shell 510.

[0055] Specifically, the coupling base shell 510 consists of two separate threaded base shells, having a first inner cavity 511 and a second inner cavity 512. The first inner cavity 511 is an inner cavity that mates with the hair clipper track 420, and the two ends of the first inner cavity 511 form opposing openings in the coupling base shell 510. The hair clipper track 420 mates through the first inner cavity 511. In this embodiment, the extension direction of the second inner cavity 512 is perpendicular to the hair clipper track 420, and it has an opening that faces outward.

[0056] The drive assembly 520 includes a drive motor 521 and a drive gear 522 disposed on the output shaft of the drive motor 521. The drive gear 522 meshes with the rack surface 420a, so that when the drive motor 521 is activated, the drive gear 522 rotates, thereby coupling the base shell 510 to travel on the rack surface 420a. Specifically, the drive gear 522 is located in the first inner cavity 511. In this embodiment, the output shaft of the drive motor 521 is coupled to the drive gear 522 through a first reduction module 523 in the form of a gearbox.

[0057] The drive assembly 530 includes a drive motor 531 and a drive bracket 532 disposed on the output shaft of the drive motor 531. The drive bracket 532 is fixedly connected to the hair cutting actuator 100. Specifically, the output shaft of the drive motor 531 points to the target head H. In this embodiment, the output shaft of the drive motor 531 is coupled to the drive bracket 532 through a second reduction module 533 in the form of a gearbox.

[0058] In this embodiment, both the drive motor 521 and the rotation motor 531 are stepper motors, which can calculate the length of the coupling base shell 510 traveling on the rack surface 420a and the rotation angle of the hair-cutting actuator 100 based on the frequency of the input signal and the duration of the signal input.

[0059] Specifically, the coupling unit 500 also includes a pressing assembly 540, which includes a plurality of radial support rollers 541 and two sets of end face pressing rollers 542 located on opposite sides of the hairdressing track 420. The radial support rollers 541 roll in contact with the concave arc surface of the hairdressing track 420, and the end face pressing rollers 542 roll in contact with the planar surface of the hairdressing track 420.

[0060] like Figure 6 and Figures 8 to 10 As shown, the haircutting actuator 100 is mounted on the haircutting track 420 via a coupling unit 500. The haircutting actuator 100 includes a proximal housing 10, an adaptive component 20, a distal housing 30, a cutting blade assembly 40, a cutting generator 50, a sensor module 60, a fine-tuning drive assembly 70, and a fine-tuning entity 80.

[0061] The distal housing 30 is mounted on the proximal housing 10 via the adaptive component 20, and the proximal housing 10, the adaptive component 20, and the distal housing 30 are sequentially coupled along the mounting direction D1, so that the corresponding directions of the proximal end 10 and the distal end 30 are the mounting direction D1.

[0062] The near-end housing 10 is provided with an exhaust fan 11, which exhausts air towards the far-end housing 30. Specifically, the near-end housing 10 is injection molded and has a near-end air vent 10a that opens towards the far-end housing 30. The exhaust fan 11 is disposed on the near-end air vent 10a and is located on the surface of the near-end housing 10 away from the far-end housing 30. Furthermore, a grid filter window 12 is provided between the exhaust fan 11 and the near-end air vent 10a.

[0063] like Figure 11 As shown, the adaptive component 20 includes an over-conduction conduit 21 and an inter-end spring 22.

[0064] The over-flow duct 21 extends along the mounting direction D1 and can be elastically retracted. The upper end of the over-flow duct 21 is connected to the exhaust fan 11. The grid filter window 12 is disposed between the exhaust fan 11 and the over-flow duct 21. When the exhaust fan 11 is blowing air, an airflow is formed in the over-flow duct 21 that flows towards the exhaust fan 11. This airflow flows through the grid filter window 12. The lower end of the over-flow duct 21 is connected to the far end cover 30. Specifically, the upper end of the over-flow duct 21 is connected to the near end air outlet 10a.

[0065] There are three inter-end springs 22. The elastic direction of the inter-end springs 22 is parallel to the mounting direction D1, and the extension axes of the three inter-end springs 22 (extending along the elastic direction) form three edges of a straight triangular prism. In this embodiment, the inter-end springs 22 are tower springs, and the larger end is connected to the near-end housing 10.

[0066] The distal housing 30 is a semi-open structure formed by injection molding, having a guide portion 31a and a bottom opening 32a, specifically, as shown in... Figure 12 and Figure 13 As shown, the distal housing 30 includes a housing body 31 and a bottom fastening plate 32 connected to each other.

[0067] Specifically, the shell body 31 is a semi-open shell that opens toward the target head. An inner shell partition 311 and a motor housing entity (not shown in the figure) are formed inside the shell body 31. The inner shell partition 311 extends toward the target head. The motor housing entity has an inner cavity surface (not shown in the figure) facing the inner shell partition 311. A motor housing sub-cavity 30f extending toward the target head is formed inside the motor housing entity. The motor housing sub-cavity 30f has an opening on its inner cavity surface. The shear generator 50 is located in the motor housing sub-cavity 30f, and its output end extends into the shell body 31.

[0068] The guide portion 31a extends along a straight line and has two open ends that extend in the same direction as itself. Specifically, the guide portion 31a is formed by the motor housing body extending outward from the far end cover 30. The guide portion 31a extends toward the target head and the extending straight line intersects the straight line where the mounting direction D1 is located at an angle. In this embodiment, the guide portion 31a protrudes in a rectangular shape, the guide channel 31b is cylindrical, and the lower opening is located near the target head.

[0069] Specifically, such as Figure 14 As shown, the bottom fastening plate 32 is threadedly connected to the shell body 31 at the opening of the shell body 31. The bottom fastening plate 32 has a bottom opening 32a and a positioning protrusion 32b. The bottom opening 32a allows the distal cover 30 to open toward the target head.

[0070] The distal end cover 30 and the shearing blade assembly 40 enclose a hair-suction cavity 30a. Specifically, the distal end cover 30 and the shearing blade assembly 40 enclose a hair-suction cavity 30a and a receiving cavity 30b. The bottom opening 32a has a first region facing the target head (not shown in the figure) and a second region not facing the target head but located near the target head (not shown in the figure). The shearing blade assembly 40 is embedded in the first region, so that the whole formed by the distal end cover 30 and the shearing blade assembly 40 is only open near the target head through the second region. The hair-suction cavity 30a is the cavity between the second region and the inner partition 311. The receiving cavity 30b is the cavity between the shearing blade assembly 40, the inner partition 311, the bottom fastening plate 32, and the inner surface of the cavity. The free end of the inner partition 311 and the shearing blade assembly 40 form an inner through narrow opening 30c, so that the hair-suction cavity 30a and the receiving cavity 30b are connected through the inner through narrow opening 30c.

[0071] The suction chamber 30a has an air inlet 30d and an over-flow port 30e. The air inlet 30d is open to the outside, and the over-flow port 30e is open to the over-flow pipe 21. Specifically, the air inlet 30d is the second region, and the over-flow port 30e is formed on the surface of the distal cover 30 near the proximal housing 10. The lower end of the over-flow pipe 21 is connected to the over-flow port 30e.

[0072] The shear generator 50 is coupled to the output of the shear blade assembly 40. Specifically, the output end of the shear generator 50 extends into the accommodating cavity 30b, and a crank wheel 51 is coaxially provided on the output end of the shear generator 50. The crank wheel 51 has a rotating coupling rod 51a extending toward the target head. A bent and extended fixed sheet metal frame 52 is also fixed on the inner surface of the cavity. One end of the fixed sheet metal frame 52 is fixed on the inner surface of the cavity, and the other end is connected to the shear blade assembly 40. The fixed sheet metal frame 52 has a positioning hole (not shown in the figure), and the positioning protrusion 32b is engaged in the positioning hole, thereby realizing the stable positioning of the relative positional relationship of the shell body 31, the bottom fastening plate 32, and the shear blade assembly 40.

[0073] The shearing blade assembly 40 is disposed on the distal housing 30, and the shearing blade assembly 40 includes a fixed blade 41 and a movable blade 42 stacked along the mounting direction D1. like Figure 15 As shown, both the fixed blade 41 and the movable blade 42 have corresponding cutting portions 42b. The cutting portions 42b have multiple hair-cutting comb teeth 42c distributed along a predetermined straight direction D2. The predetermined straight direction D2 is perpendicular to the mounting direction D1. The sides of the hair-cutting comb teeth 42c form hair-cutting edge edges (not shown in the figure). The hair-cutting edge edges of the fixed blade 41 and the movable blade 42 correspond to each other and form hair-penetrating gaps (not shown in the figure). Thus, the cutting portions 42b of the fixed blade 41 and the movable blade 42 form multiple hair-penetrating gaps in a grid shape along the mounting direction D1. The passing direction of the hair-penetrating gaps extends along the mounting direction D1.

[0074] Specifically, both the fixed blade 41 and the movable blade 42 have an integrally formed blade holder 32a and a shearing part 42b. The blade holder 42a corresponds to the receiving cavity 30b, and the shearing part 42b corresponds to the suction cavity 30a, thereby connecting the suction cavity 30a and the hair passage pipe 21 to form an extraction channel between the exhaust fan 11 and the shearing blade assembly 40.

[0075] The end face of the fixed blade 41 facing the target head is used as the mating end face (not shown in the figure). The mating end face is exposed through the bottom opening 32a and the mating end face faces the surface of the target head along the mounting direction D1. The cutting section 42b includes multiple hair-cutting comb teeth 42c, which are distributed along a predetermined straight direction D2. The sides of the hair-cutting comb teeth 42c form hair-cutting edge blades (not shown in the figure). The hair-cutting edge blades of the fixed blade 41 and the movable blade 42 correspond to each other and form hair-penetrating gaps. That is, the cutting section 42b of the fixed blade 41 and the movable blade 42 forms multiple hair-penetrating gaps in a grid shape along the mounting direction D1 (not shown in the figure). The lower end of the hair-passing pipe 21 is connected to the hair-penetrating gaps through the hair-suction chamber 30a. The hair-cutting edge blades are located at the edge of the air inlet 30d. The hair-suction chamber 30a is open to the target head through the hair-penetrating gaps, and the hair-penetrating gaps are located at the edge of the air inlet 30d. The hair-passing pipe 21 is connected to the hair-penetrating gaps through the hair-suction chamber 30a. Specifically, the cutting section 42b is in the shape of open comb teeth.

[0076] Specifically, the fixed blade 41 is fixed on the inner wall of the bottom fastening plate 32. The fixed blade 41 has a movable straight groove 41a facing the movable blade 42. The movable straight groove 41a extends along a predetermined straight direction D2. The fixed blade 41 is connected to the fixed sheet metal frame 52. The fixed sheet metal frame 52 is fixed on the inner surface of the cavity. The fixed blade 41 is fitted into the first area, thereby exposing the fitting end face outward. The haircutting comb teeth 42c are located at the edge of the air inlet 30d and face outward. The lower surface of the fixed blade 41 fits against the target head, and the direction of the hair gap is perpendicular to the lower surface of the fixed blade 41.

[0077] Specifically, the movable blade 42 has a movable protrusion 423, a blade body 422, and a coupling entity 421 that are sequentially moved away from the fixed blade 41 along the mounting direction D1. The movable protrusion 423 and the coupling entity 421 are both injection molded parts, while the blade body 422 is a metal part. The blade body 422 has a welding through hole (not shown in the figure) extending along the mounting direction D1. The movable protrusion 423 and the coupling entity 421 are fused together through the welding through hole by a thermal fusion process. The movable protrusion 423 cooperates with the movable straight groove 321a, thereby enabling the movable blade 322 to move relative to the fixed blade 321 along a predetermined straight direction D2. The coupling entity 421 has a direct-motion coupling groove 421a and a limiting groove 421b. The extension direction of the direct-motion coupling groove 421a is perpendicular to the predetermined straight direction D2. The number of limiting grooves 421b is a pair, and the pair of limiting grooves 421b are arranged on opposite sides of the direct-motion coupling groove 421a along the predetermined straight direction D2.

[0078] The hair-cutting generator 50 drives the fixed blade 41 and the movable blade 42 to move repeatedly in opposite directions along a predetermined straight line D2, thereby causing the hair-penetrating gap to continuously open and close. When the hair-penetrating gap is open, the hair of the target head is inserted into the hair gap; when the hair-penetrating gap is closed, the hair inserted into the hair gap is cut off. Specifically, the rotating coupling rod 51a is inserted into the direct-acting coupling slot 421a. When the hair-cutting generator 50 drives the crank wheel 51 to rotate, the rotating coupling rod 51a performs a circular motion, thereby driving the movable blade 42 to move back and forth along the predetermined straight line D2 through the coupling entity 421. After the hair-penetrating gap is closed and the hair is cut off, the cut hair is driven by the directional airflow between the exhaust fan 11 and the air inlet 30d, and is sucked away from the surface of the target head through the hair suction chamber 30a and the hair passage pipe 21.

[0079] Specifically, during the haircutting process, the adaptive spacing between the target head surface and the external moving platform depends on the adaptive component 20. That is, the adaptive effect is achieved through the retractability of the hair passage 21 and the three inter-end springs 22, rather than the external moving platform itself.

[0080] The shearing blade assembly 40 also includes a pair of two-dimensional elastic rods 43. One end of the two-dimensional elastic rod 43 is fixed to the fixed blade 41, and the other end is inserted into the limiting groove 421b. The two-dimensional elastic rod 43 has a first elastic direction and a second elastic direction. The first elastic direction is parallel to the predetermined straight line direction D2, and the second elastic direction is parallel to the mounting direction D1. The two-dimensional elastic rod 43 provides a buffer for the non-uniform speed movement of the movable blade 42 in the predetermined straight line direction D2 through the first elastic direction. The two-dimensional elastic rod 43 presses the movable blade 42 against the fixed blade 41 in the mounting direction D1 through the second elastic direction. Specifically, the pair of two-dimensional elastic rods 43 are an integral structure.

[0081] The sensor module 60 includes a sensor housing 61 and a position sensor 62.

[0082] The position sensor 62 is fixed on the remote housing 30. Specifically, the position sensor 62 is a gyroscope sensor. The position sensor 62 is fixed inside the sensor housing 61, and the sensor housing 61 is fixed on the guide part 31a.

[0083] like Figure 16 and ​ As shown, the fine-tuning drive assembly 70 is used to drive the fine-tuning entity 80 to move closer to or away from the mating end face. The fine-tuning drive assembly 70 includes a cooperating electric lead screw 71 and a moving nut 72.

[0084] Specifically, the electric lead screw 71 and the moving nut 72 form a lead screw and nut structure. In this embodiment, the electric lead screw 71 has a lead screw motor 71a, a reduction gear set 71b and a lead lever body 71c coupled in sequence.

[0085] When the remote cover 30 moves at the target head, the position sensor 62 sends a fine-tuning signal, and the fine-tuning drive assembly 70 is activated based on external commands and the fine-tuning signal.

[0086] The fine-tuning entity 80 has a bent and integrally continuous fine-tuning base 81 and a fine-tuning comb plate 82.

[0087] The fine-tuning base 81 and the electric lead screw 71 are inserted from both ends of the guide channel 31b of the guide part 31a, respectively. The fine-tuning base 81 has a coupling channel 81a and an insertion through hole 81b that extend perpendicularly to each other and are connected.

[0088] The coupling channel 81a and the fine-tuning base 81 extend in the same direction and are open at both ends. The electric lead screw 71 is inserted into the coupling channel 81a, and the moving nut 72 is fitted into the insertion through hole 81b. The opposite sides of the moving nut 72 interfere with the inner wall of the insertion through hole 81b, so that the fine-tuning entity 80 is movably mounted on the guide part 31a through the fine-tuning base 81.

[0089] The fine-tuning comb plate 82 is disposed between the contact end face and the target head along the mounting direction D1. The fine-tuning comb plate 82 has comb teeth 82a, which correspond to the hair penetration gap in the mounting direction D1. Specifically, the fine-tuning comb plate 82 is in the shape of open comb teeth that extend in the same direction as the hair cutting comb teeth 42c, and the extension length of the fine-tuning comb plate 82 is greater than the extension length of the hair cutting comb teeth 42c. When the fine-tuning drive component 70 is activated and drives the fine-tuning entity 80 to move, the fine-tuning comb plate 82 moves closer to or further away from the mating end face.

[0090] Specifically, the wearable component 200 is equipped with a control unit (not shown in the attached figure). The control unit is used to issue or receive various external control commands. These commands control the actions of various related drive components on the wearable hairdressing device 1000, including the forward rotation, reverse rotation, and stop rotation of various drive components (including the lifting motor 320, drive motor 521, drive rotation motor 531, clipper generator 50, and lead screw motor 71a). Thus, the haircutting actuator 100 forms a haircutting path on the target head by executing the three steps of the above-mentioned automatic haircutting method.

[0091] The above embodiments are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Various modifications or variations that can be made by those skilled in the art without creative effort within the scope of the appended claims are still within the scope of protection of this patent.
