[0030] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate an example, illustration, or description. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being more preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0031] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, features defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0032] In the description of the embodiments of the present application, the term "at least one" refers to one or more, and "plurality" refers to two or more. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can represent: a, b, c, ab, ac, bc, or abc, where a, b, and c can be single or multiple.

[0033] In the description of the embodiments of this application, the term "and / or" refers to and encompasses any and all possible combinations of one or more of the associated listed items. The term "and / or" describes an association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this application generally indicates that the associated objects are in an "or" relationship.

[0034] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0035] As used herein, "perpendicular" and "equal" include the conditions described and conditions similar to the conditions described, where the range of the similar conditions is within an acceptable deviation range, where the acceptable deviation range is determined by a person of ordinary skill in the art taking into account the measurement in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system). For example, "perpendicular" includes absolute perpendicularity and approximate perpendicularity, where the acceptable deviation range for approximate perpendicularity can also be, for example, a deviation within 10°. "Equal" includes absolute equality and approximate equality, where the acceptable deviation range for approximate equality can be, for example, that the difference between the two is less than or equal to 10% of either of them.

[0036] In a hair trimming device's blade module, the drive motor typically consists of a stator, a mover, and a frame. Both the stator and mover are fixed to the frame. When the stator is energized, it drives the mover in linear reciprocating motion. The mover is connected to a drive shaft, which in turn is connected to the moving blade. The reciprocating motion of the mover drives the moving blade.

[0037] Typically, to ensure waterproofing, the drive motor is mounted within the housing of the cutter head module, with a drive shaft extending from the housing to connect to the moving blade outside. A sealing ring is fitted over the drive shaft at a hole in the housing to provide waterproofing and protect the stator of the drive motor.

[0038] However, the reciprocating motion of the drive shaft drives the sealing ring through high-frequency motion. Furthermore, the exposed seal ring is exposed to stubble, chemicals, and other substances, which can damage it and degrade its sealing performance. This poor sealing performance can lead to a poor seal between the housing and the drive shaft, impairing the waterproofing of the cutter head module, and potentially damaging the stator components. Furthermore, stubble from shaving easily accumulates on the seal ring, making it difficult to clean and resulting in an odor over time.

[0039] In order to solve the above technical problems, the present application provides a hair trimming device. The specific structure of the hair trimming device provided by the present application will be described in detail below.

[0040] The present application provides a hair trimming device, which includes but is not limited to a shaver, a hair clipper, or a nose hair trimmer.

[0041] See also Figure 1 , Figure 1 Schematic diagram of a hair trimming device 1000 provided in this application. The hair trimming device 1000 includes a body 200 and a cutter head module 100.

[0042] The body 200 can support the cutter head module 100 .

[0043] The body 200 may integrate some functional components necessary for realizing the functions of the hair trimming device 1000, including but not limited to a circuit board, a power battery, etc. The structure of the body 200 is well known to those skilled in the art and will not be described in detail here.

[0044] The cutter head module 100 is mounted on the body 200. Specifically, the cutter head module 100 is mounted on one end of the body 200 along the second direction B. That is, the cutter head module 100 and the body 200 are arranged in the second direction B, and the cutter head module 100 is mounted on the body 200. When using the hair trimming device 1000, the user can hold the body 200 for ease of use.

[0045] The following will focus on the structure of the cutter head module 100 in detail.

[0046] See also Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , Figure 2 Based on Figure 1 A schematic diagram of the cutter head module 100 is shown; Figure 3 Based on Figure 2 The cutter head module 100 is shown in a cross-sectional view at line AA; Figure 4Based on Figure 1 A schematic diagram of the cutter head module 100 from another perspective is shown; Figure 5 Based on Figure 4 The cutter head module 100 is shown in a cross-sectional view along line BB. The cutter head module 100 comprises a housing 1 , a blade assembly 3 , a moving component 4 and a stator component 5 .

[0047] The housing 1 serves as a supporting “skeleton” of the cutter head module 100 , and plays a role in supporting the blade assembly 3 , the mover component 4 and the stator component 5 .

[0048] The material of the housing 1 includes but is not limited to metal, plastic, and a combination of the two.

[0049] The shape of the housing 1 includes but is not limited to a cylindrical, cubic, or irregular shape. The housing 1 can be a single structure or can be formed by splicing multiple shell parts.

[0050] Please continue reading Figure 3 and Figure 5 The housing 1 is provided with a space divider 2. The material of the space divider 2 includes, but is not limited to, metal, plastic, or a combination thereof. The shape of the space divider 2 includes, but is not limited to, a flat plate or a curved shape. The connection between the space divider 2 and the housing 1 includes, but is not limited to, gluing, welding, snapping, screw connection, or magnetic attraction.

[0051] The space divider 2 can divide the space in the housing 1 into a first cavity 11 and a second cavity 12 which are not connected to each other.

[0052] Exemplarily, the arrangement direction of the first cavity 11 and the second cavity 12 is the second direction B. In other examples, the first cavity 11 and the second cavity 12 may also be arranged along other directions.

[0053] Please refer to Figure 3 and Figure 5 The housing 1 has a mounting opening 13 communicating with the first cavity 11, and the blade assembly 3 is mounted at the mounting opening 13. The shape of the mounting opening 13 includes but is not limited to a rectangle, a circle, an ellipse or a special shape.

[0054] The blade assembly 3 includes one or more blade structures, wherein a plurality refers to two or more.

[0055] Each blade structure includes a movable blade 31 and an outer blade net 32 ​​.

[0056] The movable blade 31 is movably arranged relative to the housing 1 .

[0057] Illustratively, the movable blade 31 can reciprocate relative to the housing 1 along a first direction A. The first direction A and the second direction B form an angle, for example, the first direction A is perpendicular to the second direction B. In other embodiments, the movable blade 31 can also rotate relative to the housing 1.

[0058] The outer blade net 32 ​​is located outside the corresponding movable blade 31. The outer blade net 32 ​​is connected to the housing 1 in a floating manner along a second direction B, allowing the outer blade net 32 ​​to float along the alignment of the outer blade net 32 ​​and the movable blade 31. This floating outer blade net 32 ​​facilitates the movement of the movable blade 31, enabling it to cooperate with the outer blade net 32 ​​to cut hair, thereby achieving the desired hair trimming effect.

[0059] The movable member 4 is movably disposed in the first cavity 11 and is connected to the movable blade 31. The movement of the movable member 4 can drive the movement of the movable blade 31.

[0060] The movable member 4 includes a magnetic member 41. The shape of the magnetic member 41 includes but is not limited to a rectangular parallelepiped or a special shape. The magnetic member 41 is a permanent magnet, for example, a magnet or magnetic steel.

[0061] The stator component 5 is disposed in the second cavity 12. The stator component 5 can cooperate with the magnetic component 41 to generate a magnetic driving force for driving the movable component 4 to move, thereby driving the movable blade 31 to achieve the function of the cutter head module 100 to trim hair.

[0062] From the above description, it can be found that by utilizing the space divider 2 to separate the housing 1 into a first cavity 11 and a second cavity 12 which are not connected to each other, and the mover component 4 is installed in the first cavity 11, and the stator component 5 is installed in the second cavity 12, the stator component 5 and the mover component 4 are installed separately and driven without contact, so that the second cavity 12 can be utilized to perform separate protection on the stator component 5, thereby improving the protection effect on the stator component 5, avoiding the problem of damage to the stator component 5 due to poor waterproof effect of the cutter head module 100 in the related art, and being beneficial to improving the service life of the stator component 5. It also avoids the setting of the sealing ring in the related art, reduces the cost, and avoids the odor problem caused by the accumulation of stubble and the like on the sealing ring.

[0063] In some embodiments of the present application, the movable member 4 is slidably disposed within the first cavity 11 along a first direction A, and the first direction A and the second direction B form an angle, for example, the first direction A and the second direction B are perpendicular. In this way, the movable blade 31 can be driven to move by sliding the movable member 4 along the first direction A. In other embodiments, the movable member 4 can also be rotatably disposed within the first cavity 11. In the following description, the movable member 4 is slidably disposed within the first cavity 11 along the first direction A as an example.

[0064] In some specific examples, in order to achieve the cooperation between the stator component 5 and the movable component 4 to drive the movable component 4 to slide along the first direction A, the magnetization direction of the magnetic component 41 is the first direction A. In other words, the arrangement direction of the south pole (S) and the north pole (N) of the magnetic component 41 is the first direction A.

[0065] Please continue reading Figure 3 and Figure 5 The stator component 5 includes a coil 51 and a stator core 52 .

[0066] Exemplarily, the stator component 5 may further include a coil support 53 . The coil 51 is wound on the coil support 53 .

[0067] The stator core 52 is connected to the coil 51. The stator core 52 can converge magnetic lines of force and increase the magnetic field strength between the coil 51 and the magnetic member 41.

[0068] When alternating current is supplied to the coil 51 of the stator component 5, the stator core 52 forms alternating magnetic poles at both ends (hereinafter referred to as the first end D1 and the second end D2) in the first direction A. Figure 5 When the magnetic poles of the first end D1 of the stator core 52 differ from the magnetic poles of the magnetic member 41 adjacent to the first end D1, the magnetic member 41 is attracted to the first end D1 of the stator core 52. At this time, the magnetic poles of the second end D2 of the stator core 52 and the magnetic poles of the magnetic member 41 adjacent to the second end D2 are the same, and the magnetic member 41 is repelled by the second end D2 of the stator core 52, thereby causing the movable component 4 to move toward the first end D1. Conversely, when the magnetic poles of the first end D1 of the stator core 52 and the magnetic poles of the magnetic member 41 adjacent to the first end D1 are the same, the magnetic member 41 is repelled by the first end D1 of the stator core 52. At this time, the magnetic poles of the second end D2 of the stator core 52 and the magnetic poles of the magnetic member 41 adjacent to the second end D2 are different, and the magnetic member 41 is attracted to the second end D2 of the stator core 52, thereby causing the movable component 4 to move toward the second end D2. In this way, the reciprocating sliding of the movable component 4 along the first direction A can be achieved.

[0069] It is worth noting that the driving principle of the stator component 5 and the mover component 4 described above is illustrated using the linear motion of the mover component 4 as an example, and this does not constitute a special limitation on the present application. In other embodiments, when the mover component 4 is rotatably disposed within the first cavity 11, the layout relationship between the coil 51 and the stator core 52, as well as the layout of the magnetic member 41 relative to the stator component 5, can be adaptively adjusted to ensure that the stator component 5 and the mover component 4 cooperate to drive the stator component 4 to rotate.

[0070] In some embodiments of this application, please continue to refer to Figure 5 , and combined with Figure 6 , Figure 6 Based on Figure 5 Schematic diagram of part of the structure of the cutter head module 100 shown. The cutter head module 100 includes an elastic member 6. The movable member 4 includes a fitting portion 421. Elastic members 6 are respectively installed between the fitting portion 421 and the housing 1 on both sides along the first direction A. When the stator component 5 is not supplied with alternating current, the movable member 4 is in an initial state, in which the elastic member 6 can be in a compressed state or in a naturally extended state. Specifically, when alternating current is supplied to the stator component 5, the movable member 4 slides back and forth in the first direction A. When the movable member 4 moves along the first direction A toward one end of the cutter head module 100 (for example Figure 5 When the left end of the stator core 52 (i.e., the side where the first end D1 of the stator core 52 is located) moves, the elastic member 6 located on the left side of the movable member 4 is in a compressed state, and as the movable member 4 moves, the compression amount of the elastic member 6 gradually increases, the movement resistance of the movable member 4 gradually increases, and the movement speed of the movable member 4 gradually decreases until it reaches the first limit position on the left side. At the first limit position, the speed of the movable member 4 is 0. Then the magnetic pole of the stator core 52 changes, and the movable member 4 moves along the first direction A toward the other end of the cutter head module 100 (for example Figure 5 As the movable member 4 moves toward the right end (i.e., the side where the second end D2 of the stator core 52 is located), the compressed potential energy of the elastic member 6 on the left side of the movable member 4 is gradually released, driving the movable member 4 to accelerate. After the movable member 4 passes the initial position, the elastic member 6 on the right side of the movable member 4 is gradually compressed. As the movable member 4 moves, the compression of the elastic member 6 on this side gradually increases, the movement resistance of the movable member 4 gradually increases, and the movement speed of the movable member 4 gradually decreases until it reaches the second extreme position on the right side, where the speed of the movable member 4 is zero.

[0071] From the above description, it can be found that the installation of the elastic member 6 between the housing 1 and both sides of the mating portion 421 along the first direction A can, on the one hand, facilitate providing a restoring force after the movable member 4 moves and reverses, and before the movable member 4 passes through the initial position, thereby increasing the movement speed of the movable member 4 after the reversal. On the other hand, it can also facilitate reducing the movement speed of the movable member 4 during the process of moving from the initial position to the position close to the limit position, so as to facilitate the timely reversal of the movable member 4 when the magnetic pole of the stator core 52 changes. In addition, by installing the elastic member 6 on both sides of the mating portion 421 along the first direction A, rather than integrally connecting the elastic member 6 with the movable member 4 or a part of the movable member 4 (for example, the driving member 42 mentioned below), it is more conducive to selecting an elastic member 6 with better elastic deformation ability and higher structural strength for assembly with the movable member 4, reducing the processing and design difficulty of the elastic member 6 and the movable member 4 as a whole, and the elastic member 6 is more stable and has a longer service life.

[0072] Exemplarily, the elastic member 6 may be made of metal, for example, aluminum, copper, iron or an alloy.

[0073] In some embodiments of this application, please continue to refer to Figure 5 and Figure 6 The movable member 4 includes a driving member 42. The driving member 42 may be made of, but not limited to, metal, plastic, or a combination thereof. The driving member 42 may be plate-shaped or block-shaped. For example, the driving member 42 may be rectangular, rounded, oval, or a special shape.

[0074] The driving member 42 is slidably mounted in the first cavity 11 along the first direction A. The magnetic member 41 is mounted on the driving member 42. The connection between the magnetic member 41 and the driving member 42 includes, but is not limited to, gluing, welding, clamping or screwing.

[0075] The driving member 42 is connected to the movable blade 31 .

[0076] In this embodiment, compared with directly connecting the magnetic part 41 with the first cavity 11 and the moving blade 31, by setting the driving part 42, a material that is easier to process can be selected to make the driving part 42, and the driving part 42 is used to support the magnetic part 41, and the driving part 42 is used to realize the connection between the movable part 4 and the first cavity 11, and between the movable part 4 and the moving blade 31, thereby simplifying the manufacturing process of the cutter head module 100 and reducing the manufacturing difficulty.

[0077] In some specific examples, the magnetic member 41 is provided on the surface of the driving member 42 facing the stator component 5. This helps to reduce the distance between the magnetic member 41 and the stator component 5 in the second direction B and improve the magnetic driving force of the magnetic member 41 and the stator component 5.

[0078] For example, please see Figure 5 The surface of the driving member 42 facing the space divider 2 is provided with a recessed receiving groove 424. The magnetic member 41 is mounted in the receiving groove 424. This helps to reduce the space occupied by the driving member 42 and the magnetic member 41 as a whole, making the structure of the cutter head module 100 more compact and reducing the volume of the cutter head module 100.

[0079] The magnetic component 41 being installed in the receiving groove 424 may mean that part of the magnetic component 41 is located in the receiving groove 424 , or the entire magnetic component 41 is located in the receiving groove 424 .

[0080] For example, the surface of the magnetic member 41 facing the space divider 2 is flush with the opening of the receiving slot 424 adjacent to the space divider 2. This, on the one hand, helps reduce the space occupied by the driving member 42 and the magnetic member 41 as a whole, making the structure of the cutter head module 100 more compact and reducing the volume of the cutter head module 100; on the other hand, compared with a case where the surface of the magnetic member 41 facing the space divider 2 is located on the side of the opening of the receiving slot 424 away from the space divider 2, it helps reduce the distance between the magnetic member 41 and the stator component 5 in the second direction B, thereby increasing the magnetic field strength between the magnetic member 41 and the stator component 5, and thus increasing the magnetic driving force between the stator component 5 and the mover component 4.

[0081] It is understandable that, in other embodiments, the magnetic member 41 may also be provided at other positions of the driving member 42 , for example, the magnetic member 41 is provided on the surface of the driving member 42 facing away from the stator component 5 .

[0082] In some embodiments of this application, please continue to refer to Figure 6 , and combined with Figure 7 and Figure 8 , Figure 7 Based on Figure 6 The schematic diagram of the cooperation of the driving member 42, the elastic member 6 and the transmission shaft 43 shown in FIG. Figure 8 Based on Figure 7 Schematic diagram of the structure shown from another perspective. When the cutter head module 100 also includes the elastic member 6, the driving member 42 is provided with a mating portion 421 at one or both ends in the third direction C. The mating portion 421 protrudes from the driving member 42. The material of the mating portion 421 includes, but is not limited to, metal, plastic, or a combination of the two. The shape of the mating portion 421 includes, but is not limited to, a rectangular block, a cylindrical shape, or a special shape.

[0083] Elastic members 6 are respectively installed on both sides of the matching portion 421 in the first direction A. In this way, the elastic member 6 can be easily arranged in the area defined by the matching portion 421 and the driving member 42, and the matching portion 421 and the housing 1 can be used to compress the elastic member 6 during the movement of the movable component 4, making the structural layout more reasonable and compact.

[0084] The third direction C forms an angle with the first direction A, and the third direction C forms an angle with the second direction B. For example, the third direction C, the second direction B, and the first direction A are perpendicular to each other.

[0085] For some specific examples, see Figure 6 、 Figure 7 and Figure 8 The driving member 42 is provided with a matching portion 421 at one end in the third direction C. Elastic members 6 are respectively installed on both sides of the matching portion 421 in the first direction A.

[0086] On this basis, for example, there are multiple driving members 42 and multiple magnetic members 41. Multiple driving members 42 correspond to multiple magnetic members 41 one by one. For example, see Figure 6 , there are two driving members 42 and two magnetic members 41. On this basis, the two driving members 42 are symmetrically arranged in the third direction C. An end of each driving member 42 away from the other driving member 42 in the third direction C is provided with a matching portion 421.

[0087] Exemplarily, the mating portion 421 and the driving member 42 are integrally formed. This improves the connection strength between the mating portion 421 and the driving member 42, simplifies the processing of the mating portion 421 and the driving member 42, and reduces the overall processing and manufacturing costs of the mating portion 421 and the driving member 42. Exemplarily, the mating portion 421 and the driving member 42 can also be connected by gluing, welding, clamping, or screws.

[0088] For example, please see Figure 6 、 Figure 7 and Figure 8 The matching portion 421 is located in the middle of the driving member 42 in the first direction A. This facilitates a more symmetrical distribution of the elastic members 6 on both sides of the matching portion 421 relative to the matching portion 421 and the driving member 42 as a whole in the first direction A. This facilitates a more uniform and symmetrical force exerted on the movable member 4 by the elastic members 6 on both sides of the matching portion 421 during the reciprocating motion of the movable member 4, thereby improving the reliability of the reciprocating motion of the movable member 4 in the first direction A.

[0089] It should be noted that the surface of the driving member 42 on which the mating portion 421 is provided has a centerline position, and the centerline position is equal to the distance between the two ends of the driving member 42 in the first direction A. The mating portion 421 being located in the middle of the driving member 42 in the first direction A means that the mating portion 421 occupies the position of the centerline position.

[0090] For example, please see Figure 6 、 Figure 7 and Figure 8 The mating portion 421 has protruding shafts 422 at both ends in the first direction A. The shape of the protruding shaft 422 includes, but is not limited to, a cylinder, a cube, a triangular prism, or a special shape. The material of the protruding shaft 422 includes, but is not limited to, metal, plastic, or a combination of the two.

[0091] When the elastic member 6 is a spring, the spring can be sleeved on the protruding shaft 422. In this way, the protruding shaft 422 can limit the elastic member 6, preventing the elastic member 6 from shifting or deviating due to telescopic deformation during the movement of the movable member 4.

[0092] For example, the protruding shaft 422 and the mating portion 421 can be integrally formed. This helps improve the connection strength between the protruding shaft 422 and the mating portion 421, simplifies the overall processing of the protruding shaft 422 and the mating portion 421, and reduces the overall processing and manufacturing costs of the protruding shaft 422 and the mating portion 421. For another example, the protruding shaft 422 and the mating portion 421 can be connected by gluing, welding, clamping, or screwing.

[0093] For example, please see Figure 7 、 Figure 8 , and also see Figure 3 and Figure 5 The cutter head module 100 further includes a transmission shaft 43. The transmission shaft 43 is provided on the surface of the driving member 42 facing away from the space divider 2 and is connected to the moving blade 31. In this way, when the movable member 4 moves, the moving blade 31 can be driven by the transmission of the transmission shaft 43.

[0094] Exemplarily, a surface of the driving member 42 facing away from the space divider 2 has a fixing platform 426. The transmission shaft 43 is fixed on the fixing platform 426. For example, the fixing platform 426 has a blind hole (not shown), and the transmission shaft 43 is interference-fitted into the blind hole (not shown).

[0095] In some embodiments of this application, please continue to refer to Figure 7 、 Figure 8 , and combined with Figure 9 , Figure 9 Based on Figure 5The cutter head module 100 shown is an enlarged view of the part circled at M. One of the guide grooves 14 and the guide blocks 423 is provided in the first cavity 11. The other of the guide grooves 14 and the guide blocks 423 is provided at both ends of the movable component 4 in the first direction A. The guide blocks 423 are slidably fitted in the corresponding guide grooves 14. That is to say, when the guide grooves 14 are provided at both ends of the movable component 4 in the first direction A, guide blocks 423 are provided at the positions of the movable component 4 at both ends in the first direction A in the first cavity 11. When the guide blocks 423 are provided at both ends of the movable component 4 in the first direction A, guide grooves 14 are provided at the positions of the movable component 4 at both ends in the first direction A in the first cavity 11. The guide grooves 14 correspond one-to-one to the guide blocks 423, and the corresponding guide grooves 14 slideably fit with the guide blocks 423. In this way, through the sliding fit between the guide groove 14 and the guide block 423, on the one hand, the assembly of the movable component 4 and the first cavity 11 can be realized, and on the other hand, it can play a guiding role for the sliding fit between the movable component 4 and the first cavity 11, thereby improving the reliability of the sliding fit between the movable component 4 and the first cavity 11.

[0096] For some specific examples, see Figure 7 、 Figure 8 and Figure 9 Guide blocks 423 are respectively provided at both ends of the movable component 4 in the first direction A, and guide grooves 14 are respectively provided at the positions at both ends of the movable component 4 in the first direction A in the first cavity 11.

[0097] Exemplarily, the driving member 42 of the mover component 4 is provided with guide blocks 423 at both ends in the first direction A. The guide blocks 423 and the driving member 42 may be integrally formed. This helps to improve the connection strength between the guide blocks 423 and the driving member 42, simplify the overall processing of the guide blocks 423 and the driving member 42, and reduce the overall processing and manufacturing costs of the guide blocks 423 and the driving member 42. Exemplarily, the guide blocks 423 and the driving member 42 may be connected by gluing, welding, clamping, or screwing.

[0098] For some specific examples, please continue to refer to 9 and combine them with Figure 5 and Figure 6, a mounting bracket 15 and a limiting member 16 are installed in the outer shell 1. The limiting member 16 is located on the side of the mounting bracket 15 facing the space divider 2. The mounting bracket 15 is provided with limiting members 16 at both ends in the first direction A. A guide groove 14 is defined between the limiting member 16 and the mounting bracket 15. In this way, compared with directly opening the guide groove 14 in the outer shell 1, by arranging the mounting bracket 15 and the limiting member 16 in the outer shell 1, and utilizing the cooperation of the mounting bracket 15 and the limiting member 16 to define the guide groove 14, the guide groove 14 can be processed on the outside of the outer shell 1, which is more convenient for processing the guide groove 14, simplifying the processing and manufacturing process of the cutter head module 100, and reducing the processing and manufacturing cost.

[0099] For example, the mounting bracket 15 and the stopper 16 are independently processed parts. In other words, the mounting bracket 15 and the stopper 16 are two separately processed parts that are then connected together by assembly. In this way, the guide groove 14 is defined by the mounting bracket 15 and the stopper 16 being assembled together.

[0100] In this embodiment, by setting the mounting bracket 15 and the limiting member 16 as independent processing parts, on the one hand, it is convenient to process the mounting bracket 15 and the limiting member 16 separately, and on the one hand, partial guide grooves 14 can be processed on the mounting bracket 15 and / or the limiting member 16 respectively, which can simplify the processing technology of the guide groove 14, reduce the processing and manufacturing difficulty of the guide groove 14, and improve the processing efficiency.

[0101] For example, please see Figure 6 The mounting bracket 15 is an annular frame. For example, the mounting bracket 15 is a rectangular frame, a circular frame, an oval frame or a special-shaped frame.

[0102] The movable member 4 is located on the inner circumference of the mounting bracket 15. In this way, the space inside the mounting bracket 15 can be conveniently utilized to arrange the movable member 4, which is beneficial to reducing the overall size of the mounting bracket 15 and the movable member 4 in the second direction B, improving the compactness of the structure of the cutter head module 100, and thus facilitating a reduction in the volume of the cutter head module 100.

[0103] On this basis, please continue to refer to Figure 6 When the cutter head module 100 includes an elastic member 6, an elastic member 6 is disposed between the mounting bracket 15 and the mating portion 421 on both sides along the first direction A. This allows the elastic member 6 to be compressed and released by the mating between the annular mounting bracket 15 and the movable member 4, resulting in a compact structure and a more rational layout.

[0104] For example, please see Figure 6A limiting shaft 151 is provided on the inner circumference of the mounting bracket 15. The shape of the limiting shaft 151 includes but is not limited to a cylindrical, cubic, prismatic or irregular shape. The material of the limiting shaft 151 includes but is not limited to metal, plastic, or a combination of the two.

[0105] When the elastic member 6 is a spring, the spring is sleeved on the limiting shaft 151. In this way, the limiting shaft 151 can limit the elastic member 6, preventing the elastic member 6 from shifting or deviating due to telescopic deformation during the movement of the movable member 4.

[0106] For example, the limiting shaft 151 and the mounting bracket 15 can be integrally formed. This helps improve the connection strength between the limiting shaft 151 and the mounting bracket 15, simplifies the overall processing of the limiting shaft 151 and the mounting bracket 15, and reduces the overall processing and manufacturing costs of the limiting shaft 151 and the mounting bracket 15. For another example, the limiting shaft 151 and the mounting bracket 15 can be connected by gluing, welding, clamping, or screwing.

[0107] In some embodiments of this application, please refer to Figure 10 , and combined with Figure 3 and Figure 5 ,in, Figure 10 Based on Figure 5 The schematic diagram of the partial structure of the tool head module 100 is shown. A groove 21 is formed on the surface of the space divider 2 facing the movable component 4. The opening shape of the groove 21 includes but is not limited to rectangular, circular, elliptical, triangular or special shape.

[0108] For example, at least a portion of the vertical projection of the movable blade 31 on the space divider 2 is located within the groove 21. In this way, the groove 21 can be used to define a hair storage space for storing hair. When the user uses the hair trimming device 1000, at least a portion of the trimmed hair can be received by the groove 21, thereby facilitating the centralized collection and cleaning of the trimmed hair.

[0109] Exemplarily, half or more of the vertical projection of the moving blade 31 on the space divider 2 is located in the groove 21. In this way, it is beneficial to utilize the groove 21 to receive more hair, thereby facilitating the centralized collection and centralized cleaning of the trimmed hair.

[0110] Exemplarily, the vertical projection of the moving blade 31 on the space divider 2 is located in the groove 21. In this way, it is beneficial to utilize the groove 21 to receive more hair, thereby facilitating the centralized collection and centralized cleaning of the trimmed hair.

[0111] For example, please see Figure 10The space divider 2 is recessed from the first cavity 11 toward the second cavity 12, forming a groove 21 on the surface of the space divider 2 facing the movable member 4 and a convex bulge on the surface of the space divider 2 facing the stator member 5. This improves the structural strength of the space divider 2.

[0112] For example, the bottom wall of the groove 21 is a plane, thereby simplifying the processing of the groove 21 and reducing the processing cost.

[0113] In some embodiments of this application, please continue to refer to Figure 3 and Figure 5 The housing 1 includes a separable first shell portion 17 and a separable second shell portion 18. The second shell portion 18 and the first shell portion 17 are both open on one side facing each other. The space divider 2 is fixed to the open side of the second shell portion 18 and, together with the second shell portion 18, encloses the second cavity 12. The space divider 2 and the first shell portion 17 enclose the first cavity 11, and the mover component 4 is mounted on the first shell portion 17.

[0114] In this way, the second shell 18 and the first shell 17 can be separated, which not only simplifies the connection structure between the two, but also facilitates the disassembly and assembly of the movable component 4 in the first cavity 11, and also facilitates the maintenance and replacement of components installed in the first shell 17 and the second shell 18. In addition, when the space divider 2 is provided with the above-mentioned groove 21 with the function of storing hair, the groove 21 of the space divider 2 can be exposed, so that the hair collected in the groove 21 can be cleaned.

[0115] For example, when the stator component 5 includes a stator core 52, the stator core 52 and the magnetic member 41 are magnetically engaged to detachably mount the second shell 18 and the first shell 17 together. In this way, the magnetic engagement between the stator core 52 and the magnetic member 41 enables the separable arrangement of the second shell 18 and the first shell 17, eliminating the need for additional assembly structures and reducing manufacturing costs.

[0116] For example, a first magnetic member (not shown) is provided on the end surface of the first shell portion 17 facing the second shell portion 18. A second magnetic member (not shown) is provided on the end surface of the second shell portion 18 facing the first shell portion 17. The first magnetic member and the second magnetic member are magnetically coupled to each other so that the second shell portion 18 and the first shell portion 17 can be detachably mounted together. In this way, the magnetic coupling of the first magnetic member and the second magnetic member can achieve a detachable connection between the first shell portion 17 and the second shell portion 18, which has a simple structure and is easy to process and manufacture.

[0117] For example, the first magnetic member is a permanent magnet and the second magnetic member is a ferromagnet. For another example, the first magnetic member is a ferromagnet and the second magnetic member is a permanent magnet. For another example, both the first magnetic member and the second magnetic member are permanent magnets.

[0118] For example, please see Figure 5 , at least a portion of the movable component 4 is located in the groove 21. When the stator component 5 includes a stator core 52, the vertical projection of the stator core 52 on the space separator 2 overlaps with the movable component 4 located in the groove 21. In this way, the provision of the groove 21 is conducive to reducing the space occupied by the movable component 4 and the space separator 2 as a whole, making the structure of the cutter head module 100 more compact and reducing the volume of the cutter head module 100; the provision of the groove 21 and the vertical projection of the stator core 52 on the space separator 2 overlapping with the movable component 4 located in the groove 21 are conducive to reducing the distance between the magnetic component 41 and the stator component 5 in the second direction B, increasing the magnetic field strength between the magnetic component 41 and the stator component 5, and thus increasing the magnetic driving force of the stator component 5 and the movable component 4.

[0119] In some embodiments of this application, please continue to refer to Figure 5 , and combined with Figure 11 , Figure 11 Based on Figure 10 The second cavity 12 is provided with an inner shell 19 .

[0120] The material of the inner shell 19 includes but is not limited to metal, plastic, and a combination of the two.

[0121] The inner shell 19 and the space divider 2 enclose an inner cavity. The stator component 5 is installed in the inner cavity. In this way, the inner shell 19 and the outer shell 1 (for example, the second shell portion 18 described above) can form a multi-layer structure. The stator component 5 is arranged in the inner cavity formed by the inner shell 19 and the space divider 2. This can improve the protection effect of the stator component 5 and the reliability of waterproofing. It is also beneficial to reduce the distance between the magnetic component 41 and the stator component 5, increase the magnetic field strength between the magnetic component 41 and the stator component 5, and thus improve the magnetic driving force of the stator component 5 and the mover component 4.

[0122] For example, please see Figure 5 , and combined with Figure 11 The cutter head module 100 includes a sealing member 7. The sealing member 7 includes but is not limited to rubber, silicone or sealant.

[0123] The sealing member 7 is provided between the inner shell 19 and the space divider 2. Thus, the provision of the sealing member 7 is conducive to improving the sealing effect between the inner shell 19 and the space divider 2, thereby improving the working reliability of the stator component 5.

[0124] In some embodiments of this application, please refer to Figure 12 , Figure 12 Based on Figure 11The assembly diagram of the space divider 2 and the stator component 5 is shown. The stator component 5 can be installed on the space divider 2. This can help reduce the distance between the magnetic component 41 and the stator component 5, increase the magnetic field strength between the magnetic component 41 and the stator component 5, and thus improve the magnetic driving force of the stator component 5 and the mover component 4.

[0125] For example, to facilitate installation of the stator assembly 5, the cutter head module 100 further includes a fixing member 54. The coil 51 and the stator core 52 are positioned between the fixing member 54 and the space divider 2. The fixing member 54 is connected to the space divider 2. Thus, the stator assembly 5 and the space divider 2 can be assembled by the fitting of the fixing member 54 and the space divider 2.

[0126] For example, a mounting boss 22 is provided between the space divider 2 and the fixing member 54. The coil 51 and the stator core 52 are located on the periphery of the mounting boss 22. The fixing member 54 is connected to the space divider 2 via the mounting boss 22. Thus, the provision of the mounting boss 22 facilitates the connection between the fixing member 54 and the space divider 2.

[0127] For example, the mounting boss 22 and the space divider 2 can be integrally formed. This helps improve the connection strength between the mounting boss 22 and the space divider 2, simplifies the overall processing of the mounting boss 22 and the space divider 2, and reduces manufacturing costs. For another example, the mounting boss 22 and the space divider 2 can be connected by gluing, welding, clamping, or screwing.

[0128] For example, when the mounting boss 22 and the space divider 2 are not integrally formed, the mounting boss 22 and the fixing member 54 can be integrally formed. This can improve the connection strength between the mounting boss 22 and the fixing member 54, simplify the overall processing of the mounting boss 22 and the fixing member 54, and reduce manufacturing costs. For another example, the mounting boss 22 and the space divider 2 can be connected by gluing, welding, clamping, or screwing.

[0129] In some examples, the first cavity 11 is located on the side of the second cavity 12 away from the body 200, and the mounting opening 13 is located at the end of the first cavity 11 away from the second cavity 12. This facilitates exposure of the blade assembly 3 for easier user access. Furthermore, the second cavity 12 can be closer to the body 200, facilitating placement of the stator assembly 5 closer to the body 200. This facilitates electrical connection between the stator assembly 5 and the circuit board within the body 200, shortening the electrical connection path.

[0130] See also Figure 13 、 Figure 14 、 Figure 15 , Figure 13 Schematic diagram of a cutter head module 100 provided in some other embodiments of the present application, Figure 14 Based on Figure 13 The cutter head module 100 is shown in a cross-sectional view at line CC; Figure 15 Based on Figure 13 The cutter head module 100 shown is an enlarged view of the part circled at N. Figures 1-12 The difference of the embodiment shown is that, for example, a rolling element 4231 is provided between the guide block 423 and the guide groove 14. In this way, the guide block 423 and the guide groove 14 are subjected to rolling friction by the rolling element 4231, and the friction resistance therebetween is relatively small, which is more conducive to the sliding of the movable member 4.

[0131] The number of the rolling element 4231 between the guide block 423 and the guide groove 14 can be one or more. The material of the rolling element 4231 includes but is not limited to metal. The rolling element 4231 includes but is not limited to balls and rollers.

[0132] For example, see Figure 15 , and combined with Figure 16 , Figure 16 Based on Figure 15 Schematic diagram of the coordination of the driving member 42, the elastic member 6, the rolling body 4231 and the transmission shaft 43 in the cutter head module 100 shown. The guide block 423 may have a spherical crown-shaped limiting groove 4232. A portion of the rolling body 4231 may be adapted in the limiting groove 4232. In this way, when the movable component 4 moves, the limiting groove 4232 may limit the rolling body 4231 and prevent the rolling body 4231 from detaching from between the guide block 423 and the guide groove 14. In other embodiments, the limiting groove 4232 may also be provided on the groove wall of the guide groove 14, for example, on the limiting member 16 and / or the mounting bracket 15.

[0133] For some specific examples, see Figure 17 and Figure 18 , Figure 17 Based on Figure 13 The cross-sectional view of the cutter head module at line DD is shown. Figure 18 Based on Figure 17A schematic diagram of a partial structure of the cutter head module shown. The bottom wall of the groove 21 is formed with a recessed portion 23A on the side of the space separator 2 facing the stator component 5, and a protruding portion 23B is formed on the side of the space separator 2 facing the movable component 4. At least a portion of the stator component 5 is located in the recessed portion 23A. In this way, the space separator 2 can be bent, which is beneficial to improving the structural strength of the space separator 2, and is beneficial to reducing the distance between the magnetic component 41 and the stator component 5 in the second direction B, thereby improving the magnetic driving force of the stator component 5 and the movable component 4, and making the structure of the cutter head module 100 more compact.

[0134] For example, the movable member 4 can be supported by the protrusion 23B. The groove 21 has sub-grooves 211 located on both sides of the protrusion 23B in the direction of movement of the movable member 4, that is, in the first direction A. In this way, as the movable member 4 slides back and forth along the first direction A, hair and other items that fall onto the protrusion 23B can be pushed into the sub-grooves 211 by the movable member 4. The sub-grooves 211 can then be used to collect the hair and other items, making it easier to clean the cutter head module 100.

[0135] In other embodiments, the groove 21 has a sub-groove portion 211 located on one side of the protrusion 23B in the first direction A.

[0136] For example, the sub-grooves 211 on both sides of the protruding portion 23B are symmetrically arranged relative to the protruding portion 23B. In this way, the structure of the entire space divider 2 can be made more symmetrical and more aesthetically pleasing.

[0137] For some specific examples, see Figure 19 , Figure 19 Based on Figure 16 Schematic diagram of another perspective of the structure shown. A matching portion 421 protruding from the driving member 42 is provided on the surface of the driving member 42 facing away from the magnetic member 41. In this way, by arranging the matching portion 421 and the magnetic member 41 on both sides of the driving member 42 respectively, it is possible to avoid the problem of the matching portion 421 occupying the layout space of the driving member 42 caused by arranging the matching portion 421 and the magnetic member 41 on the same side of the driving member 42, thereby facilitating the magnetic member 41 to be arranged larger and improving the magnetic driving force of the moving part 4 and the stator part 5. In addition, when the magnetic member 41 is arranged on the side of the driving member 42 facing the space separator 2, the matching portion 421 is located on the side of the driving member 42 facing away from the space separator 2. In this way, the driving member 42 and the magnetic member 41 can be used to shield the matching portion 421 as a whole, which not only plays a protective role on the matching portion 421, but also makes the structure more neat and beautiful.

[0138] For example, please see Figure 19The mating portion 421 includes two sub-mating plates 4211. The two sub-mating plates are provided on both sides of the transmission shaft 43 in the first direction A. An elastic member 6 is arranged between one of the sub-mating plates 4211 and the housing 1, and an elastic member 6 is arranged between the other sub-mating plate 4211 and the housing 1.

[0139] Illustratively, at least one end of the driving member 42 in the third direction C and a surface of the driving member 42 facing away from the magnetic member 41 may be provided with a matching portion 421 protruding from the driving member 42 .

[0140] It is understood that in other embodiments, the matching portion 421 located on the surface of the driving member 42 facing away from the magnetic member 41 may also be defined by one or more fixing platforms 426. Alternatively, in other embodiments, the matching portion 421 may also refer to the driving member 42.

[0141] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples without contradicting each other.

[0142] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
