Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent manufacturing equipment, and in particular to an intelligent hair cutting device. Background Art

[0002] Currently, most explorations and attempts at fully automated haircutting devices are still in the conceptual design or prototype development stages. The vast majority of proposals mimic or utilize methods similar to those of industrial robotic arms coupled with various sensors, aided by complex computer algorithms, to replicate the manual haircutting process. These solutions are complex, expensive, and lack the dexterity of a human hand to perform complex haircuts. Some, based on handheld clippers, utilize sensors and computer-assisted positioning systems to assist in semi-automated haircutting, but these systems fall short of fully automated processes and fail to integrate new AI technologies for self-design and hairstyle selection.

[0058] In order for those skilled in the technical field to better understand the technical solutions in the specification, the technical solutions in the specification will be clearly and completely described below in combination with the drawings in the specification. Obviously, the described embodiments are only part of the embodiments of the specification, not all. Based on the embodiments in the specification, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the specification.

[0059] In the embodiments of the present application, the terms "first", "second", etc. are used to distinguish different elements from the point of view, but do not mean the spatial arrangement or time sequence of these elements, and these elements should not be limited by these terms. The term "and / or" includes any one and all combinations of one or more of the associated listed terms. The terms "include", "contain", "have" and the like mean the presence of the stated features, elements, elements or components, but do not exclude the presence or addition of one or more other features, elements, elements or components.

[0060] In the embodiments of the present application, the singular form "one", "the" and the like can include the plural form, which should be broadly understood as "one" or "a kind" rather than limited to the meaning of "one"; In addition, the term "said" should be understood to include both singular and plural forms, unless the context clearly indicates otherwise; In addition, the term "according to" should be understood as "at least partially according to", and the term "based on" should be understood as "at least partially based on", unless the context clearly indicates otherwise; In addition, the meaning of the term "a plurality of" is two or more, unless otherwise stated.

[0061] In view of the fact that there is no full-automatic hair cutting device in the prior art (only available handheld or semi-automatic hair cutting devices exist in the prior art, which can only assist people to complete certain operations, and full-automatic hair cutting cannot achieve the desired results or can only complete basic and simple operations), see Figure 1 and Figure 2 The present application provides an intelligent hair cutting device, which comprises:

[0062] A helmet 1 is provided on the user's head, and the user's head and the inner wall of the top of the helmet are provided with a first reserved space;

[0063] Two guide rails 2 are provided on both sides of the user's ears in the helmet, and the guide rails extend in the corresponding plane on the left and right sides of the user;

[0064] An arc-shaped track 3 is slidably connected with the two guide rails 2 and can slide along the guide rails 2;

[0065] A hair cutting part 4 is slidably connected with the arc-shaped track 3 and is provided in the first reserved space.

[0066] Guide rails 2 are provided at the positions corresponding to the user's left and right ears, respectively. The guide rails 2 are generally in the shape of a right angle, but the right angles are rounded to allow the haircutting part to move more easily from the horizontal section of the guide rails 2 (corresponding to haircutting the top and sides of the user's head) to the vertical section of the guide rails 2 (corresponding to haircutting the back of the user's head).

[0067] It should be noted that the haircutting part 4 can slide along the curved track 3 to achieve left-right movement of the haircutting part relative to the user's head, and the curved track 3 can slide along the guide rail 2 to achieve front-to-back movement of the haircutting part relative to the user's head, and ultimately achieve haircutting of all parts of the user's head.

[0068] In addition, the guide rail 2 is fixedly connected to the helmet, i.e., the relative position of the guide rail 2 and the helmet 1 does not change. However, the curved track 3 is slidably connected to the helmet 1, i.e., the relative position of the curved track 3 relative to the helmet 1 changes during the haircut process.

[0069] The helmet 1 is a rigid structure, and its shape is basically consistent with the outline of a human head. It can be put on the user's head to form a haircutting space between the user's head and the helmet. The helmet 1 can be set to different sizes according to other factors such as the user's age and gender.

[0070] As can be seen from the above description, the intelligent hair cutting device provided in the embodiment of the present application includes: a helmet, which is mounted on the user's head, and a first reserved space is provided between the user's head and the inner wall of the top of the helmet; two guide rails, respectively provided inside the helmet at the sides corresponding to the user's ears, and the guide rails extend in the corresponding planes on the left and right sides of the user; a curved track, which is slidably connected to the two guide rails and can slide along the guide rails; and a hair cutting part, which is slidably connected to the curved track and is provided in the first reserved space.

[0071] The intelligent haircutting device provided by this invention can fully realize autonomous haircutting and can design and complete the entire haircutting process according to the user's needs. It will be widely used by individuals and families. Users can complete their haircuts at any convenient time and place, and achieve unlimited and high-frequency haircuts at a controllable cost (just like using an electric shaver), and can continuously change different hairstyles to suit their needs. It can also help people with disabilities, special occupations, field workers, soldiers on missions, residents of remote areas, and others to meet their own haircut needs.

[0072] In some embodiments, see Figure 2 , the guide rail comprises:

[0073] The horizontal section 2-1 extends in a direction parallel to the front-to-back direction of the helmet 1 ( Figure 2 The arc track 3 and the haircutting part 4 are used to cut the front and upper part of the user's head;

[0074] The vertical section 2-2 extends in a direction parallel to the vertical direction of the helmet 1 and is used to cooperate with the arc-shaped track 3 and the haircutting part 4 to cut the back of the user's head;

[0075] The bending section 2-3 is used to connect the horizontal section 2-1 and the vertical section 2-2, and to enable the arc track 3 to move smoothly from the horizontal section 2-1 to the bending section 2-3.

[0076] In some embodiments, two second reserved spaces are provided between the user's head and the inner walls on the left and right sides of the helmet 1; the second reserved spaces are used by the haircutting part 4 to cut the side of the user's head.

[0077] In some embodiments, see Figure 2 , the intelligent hair cutting device further includes:

[0078] Two vertical tracks 5( Figure 2 Only the vertical track 5 on the left ear side of the user is shown), which is respectively provided in the two second reserved spaces, and the vertical track 5 is fixedly connected to the horizontal section 2-1 of the guide rail 2 on the same side, and the extension direction is parallel to the up and down direction of the helmet 1;

[0079] The vertical track 5 is used to make the barber part slide along the vertical track 5 when the end of the curved track 3 is connected to the end of the vertical track 5 (similar to the switch switching of train tracks) to trim the hair on both sides of the user's head (including hair and beard).

[0080] It can be understood that since the guide rail 2 is fixedly connected to the helmet 1, and the vertical rail 5 is also fixedly connected to the guide rail 2, the vertical rail 5 is also fixedly connected to the helmet 1, and the vertical rail 5 is different from the arcuate rail 3 in shape, and the other specifications are the same as the arcuate rail 3, so that the hair cutting part 4 can smoothly transition from the arcuate rail 3 to the vertical rail 5 ( Figure 2 The middle arc track 3 is aligned with the end of the vertical track 5. Figure 3 The ends of the middle curved track 3 and the vertical track 5 are not aligned).

[0081] In some embodiments, see Figure 4 , the hair cutting section 4 comprises:

[0082] The electric cutter head 4-1 is arranged on the arc track 3 and is used to trim the user's hair;

[0083] a comb 4-2 arranged between the electrically operated cutter head and the user's scalp and abutting the user's scalp;

[0084] a lifting screw 4-3 for driving the electrically operated cutter head 4-1 to move up and down;

[0085] an electrically operated telescopic rod 4-4 for driving the comb 4-2 to move up and down.

[0086] In some embodiments, the hair cutting unit 4 can rotate around a direction perpendicular to a straight line formed by the two end points of the arc-shaped track 3.

[0087] Referring to Figure 2 , the cutter head of the hair cutting unit is shown to be directed towards the user's face, the hair cutting unit can be rotated to a direction opposite to the direction in which the cutter head is directed towards the user's face, i.e. the electrically operated cutter head 4-1 and the comb 4-2 can be rotated by 180° (or about 180°), and the reason for this design is as follows:

[0088] The hair on the top of the head of a user with longer hair generally grows forward, while the hair on the back of the head generally grows downward (see Figure 5 and Figure 6 , of course, there are also some people whose hair grows in a direction different from this, but the above designs can be adapted), and thus when cutting the hair on different parts of the user's head, it is preferable to adjust the direction of the hair cutting unit in time according to the direction in which the user's hair grows, so as to obtain a better hair cutting effect.

[0089] It should be noted that the above electrically operated cutter head is detachable, and can be replaced by other types of cutter heads to meet the hair cutting needs of different users, for example, it can be replaced by a cutter head with a smaller size to cut the user's hair into a hairstyle with a stronger individuality, for example, to cut the hair into a hairstyle with a certain logo or character image. In addition, the electrically operated cutter head can also be replaced by an inkjet device to dye the user's hair, and it can be understood that such hair dyeing can be performed on all of the user's hair or on part of the user's hair.

[0090] In addition, the electrically operated cutter head can also be replaced by other devices for removing hair (such as an ultrasonic hair removal device or a laser pen, etc.) to achieve the effect of being able to draw any desired pattern on the user's hair, and other replacement devices can be used to complete the effect of having a fashionable and creative hairstyle.

[0091] In some embodiments, considering that head shapes differ from person to person, the hair cutting unit further comprises:

[0092] a resilient member arranged at the connection between the electrically operated telescopic rod and the comb for abutting the comb to the user's scalp.

[0093] In some embodiments, referring to Figure 1, an intelligent hair cutting device further includes:

[0094] Two rotation drive parts 6 are respectively arranged on the outside of the helmet 1 corresponding to the two sides of the user's ears. The rotation drive parts 6 are connected to the arc track 3 on the same side through a transmission member, and are used to make the arc track 3 slide along the guide rail 2 under the drive of external rotation.

[0095] In some embodiments, see Figure 2 , an intelligent hair cutting device further includes:

[0096] A first motor (not shown in the figure) is used to drive the arc track 3 to slide along the guide rail 2;

[0097] The second motor 7 is used to drive the hair cutting part to slide along the arc track.

[0098] It can be understood that, compared with the above-mentioned rotating drive unit 6, the first motor is another source of moving power for the arc track. These two methods can cooperate with each other to cope with different working conditions and achieve better haircutting effects.

[0099] The first motor can be driven by a stepping motor or other forms of electric motor to control the front-back and up-down movement of the arc track and the angular rotation change from the top to the back of the head.

[0100] In some embodiments, a smart hair cutting device further includes:

[0101] An annular inflatable airbag is provided on the inner wall of the helmet and is fitted over the neck and face of the user to fix the relative position of the user's head and the helmet and to prevent cut hair from falling outside the helmet;

[0102] The hair suction part is arranged through the preset hole of the helmet and is used for sucking the cut hair to the outside of the helmet.

[0103] The annular inflatable airbag can provide a soft seal that is more comfortable for the user. The annular inflatable airbag can have an inflation port and a deflation port. The inflation port can be connected to an air storage bag or an electric air pump outside the helmet 1 to allow gas to enter the self-inflating device. A sealing plug can be inserted into the deflation port. When deflation is required (for example, after a haircut), the sealing plug can be pulled out to deflate the self-inflating device through the deflation port.

[0104] For example, the self-inflating device can also be a cheese-type self-inflating cushion, which contains sponge and chemicals that can absorb gas. When the air inlet of the cushion is opened, air can be automatically inhaled, and exhaust can be exhausted by squeezing or using an air pump.

[0105] The annular inflatable air bag also plays a role of reinforcing the helmet and the head of the user, i.e. preventing the helmet from moving relative to the head of the user during the haircut process, thereby affecting the haircut accuracy.

[0106] The helmet 1 can be provided with an adapter hole which is in communication with the haircut space, so that a hair suction part (e.g. a vacuum cleaner) can be connected to the adapter hole during the haircut process to suck out the hair cuttings in the haircut space.

[0107] In some embodiments, the intelligent haircut device further comprises:

[0108] The processor is configured to acquire a moving track of the comb during the haircut process of the user, and simulate and store a 3D head contour of the user according to the moving track; wherein the 3D head contour is used to generate a plurality of simulated hairstyles for the user to select.

[0109] Specifically, the three-dimensional coordinate data during the movement along the arc-shaped track in a manner of keeping in close contact with the scalp of the user is acquired by the comb, and the 3D head contour of the user is established and stored according to the three-dimensional coordinate data, so as to serve as a reference contour for subsequent haircuts, thereby facilitating the determination of the haircut length based on the reference contour. Specifically, for example, after the switch button of the intelligent haircut device is turned on, the intelligent haircut device can first establish the 3D scalp contour, and generate simulated hairstyles for the user to select based on the 3D scalp contour. In addition, the ideal hairstyle can also be designed and selected for the user in combination with the developing AI artificial intelligence, so that the user can complete the self-design and selection of the suitable hairstyle, and the entire haircut process can be automatically completed. The user only needs to select the designed hairstyle on the mobile phone APP, and the ideal hairstyle can be obtained by one-key triggering. The ideal hairstyle can be reproduced at any time and anywhere, and is not limited by the number and frequency of times.

[0110] The real-time data of the entire haircut process are transmitted back to the software end, and are compared and verified with the previous head scanning contour in real time, so as to generate a real-time haircut animation effect. If the user has doubts or finds problems during the haircut process, the haircut process can also be paused or terminated through the APP software. Of course, a manual emergency button is also provided on the helmet, and the user can stop and turn off the entire haircut device at any time, so as to prevent any unsafe situation from occurring.

[0111] Mobile phone APP or computer software that can be remotely controlled (can complete all electrical control operations with integrated circuits, and can transmit data and device operation status to the software part in real time with the hardware part, and according to the data and device status, the software front-end interface will meet the individual needs of customers to design and select their own suitable hair styles, and can recommend optimized hair styles according to the real-time data of each user's hair cutting, and realize new adjustments or even a completely new design in the next hair cutting process. The mobile phone APP will be compatible and adaptable with external AI hair style design software to meet the diversified design and try of customers. The mobile phone APP also has more humanized and convenient functions such as face scanning and 3D real-time hair style design effect picture).

[0112] Further, the intelligent hair cutting device can further include a power control module, a Bluetooth module for transmitting data and control instructions, and a battery and other accessory circuit modules, and the Bluetooth module can be connected with a user terminal (such as a mobile phone or a touch display screen provided with the intelligent hair cutting device). The control system of the present application is integrated on a circuit board.
