Description

Technical Field

[0001] This application relates to the field of hair trimming technology, and in particular to a blade module and a hair trimming device. Background Technology

[0002] Hair trimming devices such as razors typically include a drive motor in their blade module. The drive motor is used to move the moving blades to trim the hair.

[0003] However, the hair trimming devices in related technologies have poor waterproofing of the blade module, which can easily lead to damage to the stator components of the drive motor. Utility Model Content

[0004] In view of this, this application provides a blade module and a hair trimming device, which are beneficial to at least to a certain extent improving the protection effect on the stator components and preventing damage to the stator components.

[0005] The blade module of the hair trimming device according to this application includes: a housing, a movable blade, a moving component, and a stator component. The housing has a spatial separator dividing it into a first cavity and a second cavity that are not electrically connected. The housing has a mounting opening communicating with the first cavity. The movable blade is disposed at the mounting opening and is movable relative to the housing. The moving component is movably disposed within the first cavity and connected to the movable blade; the moving component includes a magnetic element. The stator component is disposed within the second cavity and can cooperate with the magnetic element to generate a magnetic driving force for driving the moving component.

[0006] According to the blade module of the hair trimming device of this application, the outer shell is divided into a first cavity and a second cavity that are not connected to each other by using a space separator. The moving part is installed in the first cavity and the stator part is installed in the second cavity. This realizes the separate installation and non-contact drive of the stator part and the moving part. Thus, the second cavity can be used to protect the stator part separately, which improves the protection effect of the stator part and avoids the problem of stator part damage caused by poor waterproof effect of the blade module in related technologies. This helps to improve the service life of the stator part, eliminates the need for a sealing ring, reduces costs, and avoids the odor problem caused by stubble and other substances accumulating on the sealing ring.

[0030] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0031] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0032] In the description of the embodiments of this application, the term "at least one" means one or more, and "more than one" means two or more. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of a single item or a plurality of 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 a single item or multiple items.

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

[0034] In the description of the embodiments of this application, unless otherwise expressly specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, "linking" 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 described situation and situations that are similar to the described situation, within an acceptable deviation range, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a 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 could be, for example, a deviation within 10°. "Equal" includes absolute equality and approximate equality, where the acceptable deviation range for approximate equality could be, for example, a difference between the two equalities less than or equal to 10% of either one.

[0036] In the blade module of a hair trimming device, the drive motor typically includes 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 to perform 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 to reciprocate.

[0037] Generally, to provide waterproof protection for the drive motor, it is installed inside the housing of the cutter head module, with the drive shaft extending from inside the housing to connect to the moving blade located outside. A sealing ring is fitted onto the drive shaft at a perforation in the housing to provide waterproofing and protect the stator components of the drive motor.

[0038] However, due to the reciprocating motion of the drive shaft, the sealing ring is driven by the drive shaft to undergo high-frequency motion. Furthermore, the exposed sealing ring comes into contact with stubble, chemicals, etc., posing a risk of damage and leading to a decrease in its sealing performance. This poor sealing performance results in inadequate sealing between the housing and the drive shaft, reducing the waterproofing of the shaving head module and potentially causing damage to the stator components. In addition, stubble tends to accumulate on the sealing ring, making it difficult to clean and causing an unpleasant odor over time.

[0039] To address the aforementioned technical problems, this application provides a hair trimming device. The specific structure of the hair trimming device provided in this application will be described in detail below.

[0040] This application provides a hair trimming device. Specifically, the hair trimming device includes, but is not limited to, a razor, a hair clipper, or a nose hair trimmer.

[0041] Please see Figure 1 , Figure 1 This is a schematic diagram of a hair trimming device 1000 provided in this application. The hair trimming device 1000 includes a body 200 and a blade module 100.

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

[0043] The body 200 can integrate some essential 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 blade module 100 is mounted on the body 200. Specifically, the blade module 100 is mounted on one end of the body 200 along the second direction B, that is, the blade module 100 and the body 200 are arranged in the second direction B, and the blade module 100 is mounted on the body 200. When the user uses the hair trimming device 1000, they can hold the body 200 for ease of use.

[0045] The structure of the cutter head module 100 will be described in detail below.

[0046] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 , Figure 2 According to Figure 1 A schematic diagram of the cutter head module 100 shown; Figure 3 According to Figure 2 The cross-sectional view of the cutter head module 100 at line AA is shown. Figure 4According to Figure 1 A schematic diagram of the cutter head module 100 from another perspective; Figure 5 According to Figure 4 The cutter head module 100 shown is a cross-sectional view at line BB. The cutter head module 100 includes: a housing 1, a cutting edge assembly 3, a moving part 4, and a stator part 5.

[0047] The outer shell 1 serves as the supporting "skeleton" of the cutter head module 100, supporting the blade assembly 3, the moving part 4, and the stator part 5.

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

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

[0050] Please continue reading. Figure 3 and Figure 5 The outer casing 1 contains a space divider 2. The material of the space divider 2 includes, but is not limited to, metal, plastic, and a combination of both. The shape of the space divider 2 includes, but is not limited to, a flat or bent shape. The connection between the space divider 2 and the outer casing 1 includes, but is not limited to, adhesive bonding, welding, snap-fitting, screw connection, or magnetic attraction.

[0051] The space divider 2 can divide the space inside the outer shell 1 into a first cavity 11 and a second cavity 12 that are not connected to each other.

[0052] For example, the first cavity 11 and the second cavity 12 are arranged in the second direction B. In other examples, the first cavity 11 and the second cavity 12 may also be arranged in other directions.

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

[0054] The blade assembly 3 includes one or more blade structures. "Multiple" refers to two or more blade structures.

[0055] Each cutting edge structure includes a moving cutting edge 31 and an outer cutting edge 32.

[0056] The moving blade 31 is movable relative to the outer casing 1.

[0057] For example, the moving blade 31 is reciprocating relative to the housing 1 along a first direction A. The first direction A forms an angle with a second direction B; for example, the first direction A is perpendicular to the second direction B. In other embodiments, the moving blade 31 may also be rotatable relative to the housing 1.

[0058] The outer blade net 32 ​​is located outside the corresponding moving blade 31. The outer blade net 32 ​​is floatingly connected to the outer shell 1 along the second direction B, so that the outer blade net 32 ​​can float along the arrangement direction of the outer blade net 32 ​​and the moving blade 31. This allows the floating of the outer blade net 32 ​​to facilitate the movement of the moving blade 31 in conjunction with the outer blade net 32 ​​to cut hair, thereby achieving the purpose of trimming hair.

[0059] The moving part 4 is movably disposed within the first cavity 11 and is connected to the moving blade 31. The movement of the moving part 4 can drive the movement of the moving blade 31.

[0060] The moving part 4 includes a magnetic element 41. The shape of the magnetic element 41 includes, but is not limited to, a cuboid or irregular shape. The magnetic element 41 is a permanent magnet, such as a magnet or a magnetic steel.

[0061] The stator component 5 is disposed within the second cavity 12. The stator component 5 can cooperate with the magnetic component 41 to generate a magnetic driving force for driving the movement of the moving component 4, thereby enabling the driving of the moving blade 31 to achieve the function of the blade module 100 trimming hair.

[0062] As described above, by using the space divider 2 to divide the outer shell 1 into a first cavity 11 and a second cavity 12 that are not interconnected, and installing the moving part 4 in the first cavity 11 and the stator part 5 in the second cavity 12, the stator part 5 and the moving part 4 can be installed separately and driven without contact. Thus, the stator part 5 can be individually protected by the second cavity 12, which improves the protection effect of the stator part 5 and avoids the problem of damage to the stator part 5 caused by the poor waterproof effect of the cutter head module 100 in related technologies. This is conducive to improving the service life of the stator part 5, and also avoids the setting of the sealing ring in related technologies, reducing costs and avoiding the odor problem caused by stubble and other substances accumulating on the sealing ring.

[0063] In some embodiments of this application, the moving part 4 is slidably disposed within the first cavity 11 along a first direction A, where the first direction A forms an angle with the second direction B, for example, the first direction A is perpendicular to the second direction B. In this way, the movement of the moving blade 31 can be driven by the sliding of the moving part 4 along the first direction A. In other embodiments, the moving part 4 may also be rotatably disposed within the first cavity 11. In the following description, the example of the moving part 4 being slidably disposed within the first cavity 11 along the first direction A will be used for illustration.

[0064] In some specific examples, in order to enable the stator component 5 and the mover component 4 to cooperate in driving the mover component 4 to slide along the first direction A, the magnetization direction of the magnetic component 41 is the first direction A. That is, the arrangement direction of the south pole (S) and 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] For example, stator component 5 may also include coil support 53. Coil 51 is wound on coil support 53.

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

[0068] When alternating current is applied to the coil 51 of the stator component 5, alternating magnetic poles are formed at both ends of the stator core 52 in the first direction A (hereinafter referred to as the first end D1 and the second end D2). Please continue reading. Figure 5 When the magnetic pole of the first end D1 of the stator core 52 is opposite to the magnetic pole of the adjacent first end D1 of the magnetic component 41, the magnetic component 41 will be attracted by the first end D1 of the stator core 52. At this time, the magnetic pole of the second end D2 of the stator core 52 is the same as the magnetic pole of the adjacent second end D2 of the magnetic component 41, and the magnetic component 41 will be repelled by the second end D2 of the stator core 52, thereby causing the mover component 4 to move towards the first end D1. Conversely, when the magnetic pole of the first end D1 of the stator core 52 is the same as the magnetic pole of the adjacent first end D1 of the magnetic component 41, the magnetic component 41 will be repelled by the first end D1 of the stator core 52. At this time, the magnetic pole of the second end D2 of the stator core 52 is opposite to the magnetic pole of the adjacent second end D2 of the magnetic component 41, and the magnetic component 41 will be attracted by the second end D2 of the stator core 52, thereby causing the mover component 4 to move towards the second end D2. In this way, the moving part 4 can be made to slide back and forth along the first direction A.

[0069] It is worth noting that the driving principle of the stator component 5 and the mover component 4 described above is an example of the linear motion of the mover component 4, which should not be construed as a specific limitation of this 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 component 41 relative to the stator component 5, will be adaptively adjusted, as long as the stator component 5 and the mover component 4 cooperate to drive the stator component 4 to rotate.

[0070] Please refer to some embodiments of this application. Figure 5 and combined Figure 6 , Figure 6 According to Figure 5 This is a schematic diagram of a portion of the structure of the cutter head module 100. The cutter head module 100 includes an elastic element 6. The moving part 4 includes a mating part 421. Elastic elements 6 are respectively installed between the mating part 421 and the housing 1 on both sides along the first direction A. When the stator part 5 is not energized, the moving part 4 is in an initial state, in which the elastic element 6 can be in a compressed state or a naturally extended state. Specifically, when the stator part 5 is energized, the moving part 4 slides back and forth along the first direction A. When the moving part 4 moves along the first direction A towards one end of the cutter head module 100 (e.g., ...), the moving part 6... 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 element 6 located on the left side of the moving part 4 is in a compressed state. As the moving part 4 moves, the compression of the elastic element 6 gradually increases, the resistance to movement of the moving part 4 gradually increases, and the speed of the moving part 4 gradually decreases until it reaches the first limit position on the left. At the first limit position, the speed of the moving part 4 is 0. Then the magnetic poles of the stator core 52 change, and the moving part 4 moves along the first direction A towards the other end of the cutter head module 100 (e.g., Figure 5 The right end of the stator core 52 (the side where the second end D2 is located) moves, and the potential energy of the elastic element 6 on the left side of the mover component 4 after being compressed is gradually released, driving the mover component 4 to accelerate. After the mover component 4 passes the initial position, the elastic element 6 on the right side of the mover component 4 is gradually compressed, and as the mover component 4 moves, the compression of the elastic element 6 on this side gradually increases, the resistance to movement of the mover component 4 gradually increases, and the speed of movement of the mover component 4 gradually decreases until it reaches the second limit position on the right side, where the speed of the mover component 4 is 0.

[0071] As described above, it can be seen that installing elastic members 6 on both sides of the mating part 421 along the first direction A between it and the outer casing 1 serves two purposes. First, it facilitates the provision of restoring force after the moving part 4 has changed direction and before it has passed its initial position, thereby increasing the movement speed of the moving part 4 after the change. Second, it also facilitates reducing the movement speed of the moving part 4 as it moves from its initial position towards its limit position, thus enabling timely reversal of the moving part 4 when the magnetic poles of the stator core 52 change. Furthermore, by installing the elastic members 6 on both sides of the mating part 421 along the first direction A, rather than integrally connecting the elastic members 6 with the moving part 4 or a part of the moving part 4 (e.g., the driving member 42 mentioned below), it is more advantageous to select elastic members 6 with better elastic deformation capacity and higher structural strength for assembly with the moving part 4. This reduces the processing and design difficulty of the elastic members 6 and the moving part 4 as a whole, and the elastic members 6 are more stable and have a longer service life.

[0072] For example, the elastic element 6 can be made of metal, such as aluminum, copper, iron or an alloy.

[0073] Please refer to some embodiments of this application. Figure 5 and Figure 6 The moving part 4 includes a driving element 42. The material of the driving element 42 includes, but is not limited to, metal, plastic, and a combination of both. The driving element 42 is plate-shaped or block-shaped, for example, the driving element 42 is a rectangular plate, a rounded rectangular plate, an ellipse, or an irregular shape.

[0074] The driving component 42 is slidably mounted within the first cavity 11 along a first direction A. The magnetic component 41 is mounted on the driving component 42. The connection between the magnetic component 41 and the driving component 42 includes, but is not limited to, adhesive bonding, welding, snap-fitting, or screw connection.

[0075] The drive component 42 is connected to the moving blade 31.

[0076] In this embodiment, compared with the direct connection between the magnetic component 41 and the first cavity 11 and between the moving blade 31, by setting the driving component 42, the driving component 42 can be made of a material that is easier to process, and the driving component 42 supports the magnetic component 41, and the driving component 42 realizes the connection between the moving part 4 and the first cavity 11 and between the moving 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 element 41 is disposed on the surface of the drive element 42 facing the stator component 5. This helps to reduce the distance between the magnetic element 41 and the stator component 5 in the second direction B, thereby increasing the magnetic driving force of the magnetic element 41 in cooperation with the stator component 5.

[0078] For example, please continue reading Figure 5 The surface of the drive member 42 facing the space divider 2 is recessed with a receiving groove 424. The magnetic member 41 is installed in the receiving groove 424. This helps to reduce the space occupied by the drive 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 term "magnetic component 41 is installed in receiving groove 424" can mean that a part of the magnetic component 41 is located in receiving groove 424, or that the entire magnetic component 41 is located in receiving groove 424.

[0080] For example, the surface of the magnetic element 41 facing the space divider 2 is flush with the opening of the adjacent space divider 2 of the receiving groove 424. In this way, on the one hand, it is beneficial to reduce the space occupied by the drive element 42 and the magnetic element 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 the side of the magnetic element 41 facing the space divider 2 located away from the opening of the receiving groove 424, it is beneficial to reduce the distance between the magnetic element 41 and the stator component 5 in the second direction B, increase the magnetic field strength between the magnetic element 41 and the stator component 5, thereby increasing the magnetic driving force between the stator component 5 and the mover component 4.

[0081] It is understood that in other embodiments, the magnetic element 41 may also be disposed at other locations on the drive element 42, for example, the magnetic element 41 may be disposed on the surface of the drive element 42 opposite to the stator component 5.

[0082] Please refer to some embodiments of this application. Figure 6 and combined Figure 7 and Figure 8 , Figure 7 According to Figure 6 The diagram shows the engagement of the drive component 42, the elastic component 6, and the transmission shaft 43. Figure 8 According to Figure 7 The diagram shows another perspective view of the structure. When the cutter head module 100 also includes the elastic element 6, the drive member 42 has a mating portion 421 at one or both ends in the third direction C. The mating portion 421 protrudes from the drive member 42. The material of the mating portion 421 includes, but is not limited to, metal, plastic, and a combination of both. The shape of the mating portion 421 includes, but is not limited to, a rectangular block shape, a cylindrical shape, or an irregular shape.

[0083] Elastic members 6 are respectively installed on both sides of the mating part 421 in the first direction A. In this way, it is convenient to arrange the elastic members 6 within the area defined by the mating part 421 and the driving member 42, and the elastic members 6 can be compressed by the mating part 421 and the outer shell 1 during the movement of the moving part 4, making the structural layout more reasonable and compact.

[0084] In this configuration, 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 specific examples, please refer to [link / reference]. Figure 6 , Figure 7 and Figure 8 The driving component 42 has a mating part 421 at one end in the third direction C. Elastic members 6 are respectively installed on both sides of the mating part 421 in the first direction A.

[0086] Based on this, for example, there are multiple driving elements 42 and multiple magnetic elements 41. The multiple driving elements 42 and the multiple magnetic elements 41 correspond one-to-one. For example, please refer to... Figure 6 There are two driving elements 42 and two magnetic elements 41. The two driving elements 42 are symmetrically arranged in the third direction C. Each driving element 42 has a mating part 421 at the end in the third direction C away from the other driving element 42.

[0087] For example, the mating part 421 and the driving member 42 are integrally molded parts. This can improve the connection strength between the mating part 421 and the driving member 42, simplify the processing technology between the mating part 421 and the driving member 42, and reduce the overall processing and manufacturing cost of the mating part 421 and the driving member 42. Alternatively, the mating part 421 and the driving member 42 can also be connected by means of adhesive bonding, welding, snap-fitting, or screws.

[0088] For example, please continue reading Figure 6 , Figure 7 and Figure 8 The mating part 421 is located at the middle of the driving member 42 in the first direction A. In this way, the elastic members 6 on both sides of the mating part 421 can be more symmetrically distributed in the first direction A relative to the mating part 421 and the driving member 42 as a whole. This is beneficial to ensure that the force applied by the elastic members 6 on both sides of the mating part 421 to the moving part 4 is uniform and symmetrical during the reciprocating motion of the moving part 4, thereby improving the reliability of the reciprocating motion of the moving part 4 along the first direction A.

[0089] It should be noted that the surface of the mating portion 421 of the driving member 42 has a centerline position, which is equidistant from 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 that centerline position.

[0090] For example, please continue reading Figure 6 , Figure 7 and Figure 8 The mating part 421 has protruding shafts 422 at both ends in the first direction A. The shape of the protruding shafts 422 includes, but is not limited to, cylindrical, cubic, triangular prism, or irregular shapes. The material of the protruding shafts 422 includes, but is not limited to, metal, plastic, and a combination of both.

[0091] When the elastic element 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 element 6, preventing the elastic element 6 from shifting or deviating due to expansion and contraction deformation during the movement of the moving part 4.

[0092] For example, the protruding shaft 422 and the mating part 421 can be integrally molded. This helps to improve the connection strength between the protruding shaft 422 and the mating part 421, simplifies the overall processing technology of the protruding shaft 422 and the mating part 421, and reduces the overall processing and manufacturing cost of the protruding shaft 422 and the mating part 421. Alternatively, the protruding shaft 422 and the mating part 421 can also be connected by means of adhesive bonding, welding, snap-fitting, or screw connection.

[0093] For example, please continue reading Figure 7 , Figure 8 And see also Figure 3 and Figure 5 The cutter head module 100 also includes a drive shaft 43. The drive shaft 43 is disposed on the surface of the drive member 42 opposite to the space divider 2 and is connected to the moving blade 31. In this way, when the moving part 4 moves, the moving blade 31 can be driven to move by the drive shaft 43.

[0094] For example, the surface of the drive member 42 facing away from the space divider 2 has a mounting platform 426. The drive shaft 43 is fixed to the mounting platform 426. For example, the mounting platform 426 has a blind hole (not shown), in which the drive shaft 43 is interference-fitted.

[0095] Please refer to some embodiments of this application. Figure 7 , Figure 8 and combined Figure 9 , Figure 9 According to Figure 5The diagram shows an enlarged view of the cutter head module 100 circled at point M. The first cavity 11 contains one of a guide groove 14 and a guide block 423. The moving part 4 has the other guide groove 14 and guide block 423 at both ends in the first direction A. The guide block 423 is slidably fitted within the corresponding guide groove 14. That is, when the moving part 4 has guide grooves 14 at both ends in the first direction A, the first cavity 11 contains guide blocks 423 at the positions of the moving part 4 at both ends in the first direction A. When the moving part 4 has guide blocks 423 at both ends in the first direction A, the first cavity 11 contains guide grooves 14 at the positions of the moving part 4 at both ends in the first direction A. The guide grooves 14 and guide blocks 423 correspond one-to-one, and the corresponding guide grooves 14 and guide blocks 423 are slidably fitted. In this way, the sliding fit between the guide groove 14 and the guide block 423 can realize the assembly of the moving part 4 and the first cavity 11, and can also guide the sliding fit between the moving part 4 and the first cavity 11, thereby improving the reliability of the sliding fit between the moving part 4 and the first cavity 11.

[0096] For some specific examples, please refer to Figure 7 , Figure 8 and Figure 9 The moving part 4 is provided with guide blocks 423 at both ends in the first direction A, and guide grooves 14 are provided in the first cavity 11 at the positions of the moving part 4 at both ends in the first direction A.

[0097] For example, the drive member 42 of the moving part 4 is provided with guide blocks 423 at both ends in the first direction A. The guide blocks 423 and the drive member 42 can be integrally formed, which helps to improve the connection strength between the guide blocks 423 and the drive member 42, simplify the overall processing technology of the guide blocks 423 and the drive member 42, and reduce the overall processing and manufacturing cost of the guide blocks 423 and the drive member 42. Alternatively, the guide blocks 423 and the drive member 42 can also be connected by means of adhesive bonding, welding, snap-fitting, or screw connection.

[0098] For some specific examples, please refer to 9, and combine them with... Figure 5 and Figure 6The housing 1 contains a mounting bracket 15 and a limiting member 16. The limiting member 16 is located on the side of the mounting bracket 15 facing the space divider 2. The mounting bracket 15 has 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 inside the housing 1, by setting the mounting bracket 15 and the limiting member 16 inside the housing 1, and using 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 housing 1, which is more convenient for processing the guide groove 14, simplifies the processing and manufacturing process of the cutter head module 100, and reduces the processing and manufacturing cost.

[0099] For example, the mounting bracket 15 and the limiting member 16 are independently machined parts. That is, the mounting bracket 15 and the limiting member 16 are two separately machined parts, which are then assembled together. In this way, after the mounting bracket 15 and the limiting member 16 are assembled together, the guide groove 14 can be defined.

[0100] In this embodiment, by setting the mounting bracket 15 and the limiting member 16 as independent processing parts, it is convenient to process the mounting bracket 15 and the limiting member 16 separately, and 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 grooves 14, reduce the processing and manufacturing difficulty of the guide grooves 14, and improve processing efficiency.

[0101] For example, please continue reading Figure 6 The mounting bracket 15 is in the shape of a ring frame. For example, the mounting bracket 15 can be in the shape of a rectangular frame, a circular frame, an elliptical frame, or an irregularly shaped frame.

[0102] The moving part 4 is located on the inner periphery of the mounting bracket 15. This allows for the use of the space inside the mounting bracket 15 to arrange the moving part 4, which helps to reduce the overall size of the mounting bracket 15 and the moving part 4 in the second direction B, improves the compactness of the cutter head module 100 structure, and thus helps to reduce the volume of the cutter head module 100.

[0103] Based on this, please continue to refer to Figure 6 When the cutter head module 100 includes elastic elements 6, elastic elements 6 are respectively arranged between the mating part 421 and the mounting bracket 15 on both sides along the first direction A. In this way, the compression and release of elastic elements 6 can be achieved by utilizing the cooperation between the annular mounting bracket 15 and the moving part 4, resulting in a compact structure and a more reasonable structural layout.

[0104] For example, please continue reading Figure 6The mounting bracket 15 has a limiting shaft 151 on its inner circumferential surface. 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 both.

[0105] When the elastic element 6 is a spring, the spring is sleeved on the limiting shaft 151. In this way, the limiting shaft 151 can limit the elastic element 6, preventing the elastic element 6 from shifting or deviating due to expansion and contraction deformation during the movement of the moving part 4.

[0106] For example, the limiting shaft 151 and the mounting bracket 15 can be integrally molded. This helps to improve the connection strength between the limiting shaft 151 and the mounting bracket 15, simplifies the overall processing technology of the limiting shaft 151 and the mounting bracket 15, and reduces the overall manufacturing cost of the limiting shaft 151 and the mounting bracket 15. Alternatively, the limiting shaft 151 and the mounting bracket 15 can also be connected by means of adhesive bonding, welding, snap-fitting, or screw connection.

[0107] In some embodiments of this application, please refer to Figure 10 and combined Figure 3 and Figure 5 ,in, Figure 10 According to Figure 5 The diagram shows a partial structural schematic of the cutter head module 100. A groove 21 is formed on the surface of the space separator 2 facing the moving part 4. The opening shape of the groove 21 includes, but is not limited to, rectangle, circle, ellipse, triangle or irregular shape.

[0108] For example, at least a portion of the vertical projection of the moving blade 31 onto 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] For example, half or more of the vertical projection of the moving blade 31 onto the spacer 2 is located within the groove 21. This allows the groove 21 to hold more hair, facilitating the centralized collection and cleaning of trimmed hair.

[0110] For example, the vertical projection of the moving blade 31 onto the space divider 2 is located within the groove 21. This allows the groove 21 to hold more hair, facilitating the centralized collection and cleaning of trimmed hair.

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

[0112] For example, the bottom wall of the groove 21 is flat. This simplifies the machining of the groove 21 and reduces machining costs.

[0113] Please refer to some embodiments of this application. Figure 3 and Figure 5 The outer casing 1 includes a separable first shell portion 17 and a second shell portion 18. Both the second shell portion 18 and the first shell portion 17 are open on their respective sides. A space divider 2 is fixed to the open side of the second shell portion 18 and, together with the second shell portion 18, forms a second cavity 12. The space divider 2 and the first shell portion 17 form a first cavity 11, and a moving part 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 them, but also facilitates the disassembly and assembly of the moving part 4 inside the first cavity 11, and also facilitates the maintenance and replacement of the parts installed in the first shell 17 and the second shell 18 respectively. Furthermore, when the space divider 2 is provided with the aforementioned groove 21 for collecting hair, the groove 21 of the space divider 2 can be exposed to facilitate the cleaning of the hair collected in the groove 21.

[0115] For example, when the stator component 5 includes a stator core 52, the stator core 52 magnetically engages with the magnetic element 41 to detachably mount the second housing portion 18 and the first housing portion 17 together. In this way, the detachable arrangement of the second housing portion 18 and the first housing portion 17 is achieved by utilizing the magnetic engagement between the stator core 52 and the magnetic element 41, 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 face of the first housing portion 17 facing the second housing portion 18. A second magnetic member (not shown) is provided on the end face of the second housing portion 18 facing the first housing portion 17. The first magnetic member and the second magnetic member magnetically engage to detachably mount the second housing portion 18 and the first housing portion 17 together. In this way, by utilizing the magnetic engagement of the first magnetic member and the second magnetic member, the first housing portion 17 and the second housing portion 18 can be detachably connected, resulting in a simple structure that is easy to manufacture.

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

[0118] For example, please continue reading Figure 5 At least a portion of the moving part 4 is located within the groove 21. When the stator part 5 includes the stator core 52, the vertical projection of the stator core 52 onto the space separator 2 overlaps with the moving part 4 located within the groove 21. This arrangement of the groove 21 helps reduce the space occupied by the moving part 4 and the space separator 2 as a whole, making the structure of the cutter head module 100 more compact and reducing its volume. Furthermore, the arrangement of the groove 21 and the overlap of the vertical projection of the stator core 52 onto the space separator 2 with the moving part 4 located within the groove 21 help reduce the distance between the magnetic element 41 and the stator part 5 in the second direction B, increasing the magnetic field strength between the magnetic element 41 and the stator part 5, thereby increasing the magnetic driving force of the stator part 5 and the moving part 4 in cooperation.

[0119] Please refer to some embodiments of this application. Figure 5 and combined Figure 11 , Figure 11 According to Figure 10 The exploded view of the structure is shown. The inner shell 19 is installed inside the second cavity 12.

[0120] The inner shell 19 may be made of materials including but not limited to metal, plastic, and a combination of the two.

[0121] The inner shell 19 and the space divider 2 form an inner cavity. The stator component 5 is installed inside the inner cavity. In this way, the inner shell 19 and the outer shell 1 (e.g., the second shell portion 18 mentioned above) can form a multi-layer structure. Placing the stator component 5 inside the inner cavity formed by the inner shell 19 and the space divider 2 can improve the protection effect of the stator component 5, improve the reliability of waterproofing, and also help 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, thereby increasing the magnetic driving force of the stator component 5 and the mover component 4.

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

[0123] The seal 7 is disposed between the inner shell 19 and the space partition 2. In this way, by providing the seal 7, the sealing effect between the inner shell 19 and the space partition 2 is improved, thereby improving the operational reliability of the stator component 5.

[0124] In some embodiments of this application, please refer to Figure 12 , Figure 12 According to Figure 11The diagram shows the assembly of the spacer 2 and the stator component 5. The stator component 5 can be mounted on the spacer 2. This helps 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 increase the magnetic driving force of the stator component 5 and the rotor component 4.

[0125] For example, to facilitate the installation of the stator component 5, the cutter head module 100 also includes a fixing member 54. The coil 51 and the stator core 52 are positioned between the fixing member 54 and the spacer 2. The fixing member 54 is connected to the spacer 2. In this way, the stator component 5 and the spacer 2 can be assembled through the cooperation of the fixing member 54 and the spacer 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 outer periphery of the mounting boss 22. The fixing member 54 is connected to the space divider 2 via the mounting boss 22. In this way, the connection between the fixing member 54 and the space divider 2 can be easily achieved by providing the mounting boss 22.

[0127] For example, the mounting boss 22 and the space divider 2 can be integrally molded. This helps to improve the connection strength between the mounting boss 22 and the space divider 2, simplifies the overall processing technology of the mounting boss 22 and the space divider 2, and reduces manufacturing costs. Alternatively, the mounting boss 22 and the space divider 2 can also be connected by means of adhesive bonding, welding, snap-fitting, or screw connection.

[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 helps to improve the connection strength between the mounting boss 22 and the fixing member 54, simplifies the overall processing technology of the mounting boss 22 and the fixing member 54, and reduces manufacturing costs. As another example, the mounting boss 22 and the space divider 2 can also be connected by means of adhesive bonding, welding, snap-fitting, or screw connection.

[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 port 13 is located at the end of the first cavity 11 away from the second cavity 12. This facilitates the exposure of the blade assembly 3 for user convenience. Furthermore, the second cavity 12 can be closer to the body 200, allowing the stator component 5 to be positioned closer to the body 200, thereby facilitating electrical connection between the stator component 5 and the circuit board within the body 200 and shortening the electrical connection path.

[0130] Please see Figure 13 , Figure 14 , Figure 15 , Figure 13 This is a schematic diagram of a cutter head module 100 provided in other embodiments of this application. Figure 14 According to Figure 13 The cross-sectional view of the cutter head module 100 at the CC line is shown. Figure 15 According to Figure 13 The diagram shows an enlarged view of the portion circled at point N in the cutter head module 100. This embodiment is similar to the one described above. Figures 1-12 The difference in the illustrated embodiment is that, for example, a rolling element 4231 is provided between the guide block 423 and the guide groove 14. In this way, rolling friction is achieved between the guide block 423 and the guide groove 14 using the rolling element 4231, resulting in relatively low frictional resistance and making it more conducive to the sliding of the moving part 4.

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

[0132] For example, please refer to Figure 15 and combined Figure 16 , Figure 16 According to Figure 15 The diagram shows the engagement of the drive member 42, elastic member 6, rolling element 4231, and drive shaft 43 in the cutter head module 100. The guide block 423 may have a spherical cap-shaped limiting groove 4232. A portion of the rolling element 4231 can fit into the limiting groove 4232. In this way, when the moving part 4 moves, the limiting groove 4232 can limit the rolling element 4231, preventing it from disengaging from between the guide block 423 and the guide groove 14. In other embodiments, the limiting groove 4232 may also be formed 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, please refer to Figure 17 and Figure 18 , Figure 17 According to Figure 13 The cross-sectional view of the cutter head module at the DD line is shown below. Figure 18 According to Figure 17The diagram shows a partial structural schematic of the cutter head module. The bottom wall plate of the groove 21 has a recess 23A on the side of the space separator 2 facing the stator component 5, and a protrusion 23B on the side of the space separator 2 facing the mover component 4. At least a portion of the stator component 5 is located within the recess 23A. This allows the space separator 2 to be bent, which improves the structural strength of the space separator 2, reduces the distance between the magnetic component 41 and the stator component 5 in the second direction B, increases the magnetic driving force of the stator component 5 in cooperation with the mover component 4, and makes the cutter head module 100 more compact.

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

[0135] In other embodiments, the groove 21 has a sub-groove 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 protrusion 23B are symmetrically arranged with respect to the protrusion 23B. In this way, the structure of the entire space divider 2 is more symmetrical and aesthetically pleasing.

[0137] For some specific examples, please refer to Figure 19 , Figure 19 According to Figure 16 The diagram shows another perspective view of the structure. A mating 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. By placing the mating portion 421 and the magnetic member 41 on opposite sides of the driving member 42, the problem of the mating portion 421 occupying the layout space of the driving member 42, which would be caused by placing both the mating portion 421 and the magnetic member 41 on the same side of the driving member 42, can be avoided. This allows for a larger magnetic member 41, increasing the magnetic driving force of the mover component 4 and the stator component 5. Furthermore, when the magnetic member 41 is located on the side of the driving member 42 facing the space divider 2, the mating portion 421 is located on the side of the driving member 42 facing away from the space divider 2. This allows the driving member 42 and the magnetic member 41 to collectively shield the mating portion 421, providing protection for the mating portion 421 and resulting in a cleaner and more aesthetically pleasing structure.

[0138] For example, please continue reading Figure 19The mating part 421 includes two sub-matting plates 4211. The two sub-matting plates are disposed on both sides of the drive shaft 43 in the first direction A. An elastic element 6 is arranged between one sub-matting plate 4211 and the outer casing 1, and an elastic element 6 is arranged between the other sub-matting plate 4211 and the outer casing 1.

[0139] For example, at least one end of the drive member 42 on the third-party direction C and the surface of the drive member 42 facing away from the magnetic member 41 may both be provided with a mating portion 421 protruding from the drive member 42.

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

[0141] In the description of this specification, specific features, structures, materials or characteristics may be combined in any suitable manner in 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 this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
