[0029] The specific structure of this application will be described in detail below.

[0030] This application provides a hair trimming device. Specifically, the hair trimming device can be a razor, a hair clipper, or a nose hair trimmer.

[0031] Please see Figure 1 and Figure 2 The hair trimming device 100 includes a body 10 and a blade module 20.

[0032] The body 10 serves to support the blade module 20. The body 10 can also be used to integrate some functional components necessary to realize the function of the hair trimming device 100, including but not limited to the circuit board, power battery, etc.

[0033] The blade module 20 includes a blade mesh component 21. As an important component of the hair trimming device 100, the blade mesh component 21 is mainly used to contact the user's skin and cut hair during the hair cutting process.

[0034] The outer surface of the blade mesh component 21 has a trimming area 21A. The outer surface of the blade mesh component 21 refers to the surface of the blade mesh component 21 that faces away from the interior of the blade head module 20, that is, the surface that comes into contact with the user's skin.

[0035] In some embodiments, please refer to Figure 4 The body 10 includes a hygiene treatment module 12. The hygiene treatment module 12 is used to perform hygiene treatment on the blade mesh component 21 of the blade module 20. For example, the hygiene treatment module 12 may be a sterilization module, and / or a cleaning module, and / or a disinfection module, that is, the hygiene treatment module 12 is at least one of a sterilization module, a disinfection module, and a cleaning module.

[0036] According to the embodiments of this application, the hair trimming device 100, by providing a hygiene treatment module 12 and using the hygiene treatment module 12 to perform hygiene treatment on the blade screen component 21, can prevent contaminants such as bacteria, viruses, and dirt on the surface of the blade screen component 21 from affecting the user's safety when using the hair trimming device 100, thereby improving the user's safety when using the hair trimming device 100. Furthermore, integrating the hygiene treatment module 12 into the body 10 can also increase the functionality of the hair trimming device 100.

[0037] In some embodiments, please refer to Figure 1 , Figure 2 as well as Figure 3 In (a), the cutter head module 20 has a first position relative to the machine body 10. (See also...) Figure 3 In (b), the blade module 20 also has a second position relative to the body 10.

[0038] The cutter head module 20 is rotatably mounted on the machine body 10 about the rotation axis O1. That is, the cutter head module 20 is mounted on the machine body 10 and is rotatable relative to the machine body 10, with the rotation center line of the cutter head module 20 relative to the machine body 10 being the rotation axis O1.

[0039] The rotatable arrangement of the cutter head module 20 relative to the machine body 10 about the rotation axis O1 allows the cutter head module 20 to switch between a first position and a second position. In this way, the rotatable arrangement between the cutter head module 20 and the machine body 10 allows the cutter mesh component 21 to be movably mounted on the machine body 10, switching between the first and second positions. In other embodiments, the cutter head module 20 may be non-rotatable relative to the machine body 10.

[0040] Please continue reading. Figure 1 , Figure 2 as well as Figure 3 In (a), when the cutter head module 20 is in a first position relative to the body 10, the cutter mesh component 21 is also in a first position, and the trimming area 21A is exposed. When the cutter head module 20 is in a second position relative to the body 10, the cutter mesh component 21 is also in a second position, and the trimming area 21A faces the body 10, so that at least a portion of the trimming area 21A is covered by the body 10.

[0041] Here, it needs to be explained that "at least part of the trimmed area 21A is covered by the body 10" means that part of the trimmed area 21A is covered by the body 10 and part is exposed outside the body 10, or it can mean that the trimmed area 21A is completely covered by the body 10.

[0042] In this way, when the user needs to use the hair trimming device 100, the blade and net component 21 can be placed in the first position where the trimming area 21A is exposed, so that the trimming area 21A can contact the user's skin and achieve the function of cutting hair; when the user does not need to use the hair trimming device 100, the blade and net component 21 can be placed in the second position where at least a part of the trimming area 21A is covered by the body 10. The body 10 covers the trimming area 21A to protect the blade and net component 21, which helps to improve the user's user experience.

[0043] In other embodiments, the switching between the first position and the second position of the blade net component 21 can also be achieved by utilizing the movable setting of the blade net component 21 relative to the body 10.

[0044] In some embodiments, the maximum rotation angle of the blade module 20 between the second position and the first position is θ. That is, when the blade module 20 switches from the first position to the second position, or from the second position to the first position, the required rotation angle is the maximum rotation angle θ. The maximum rotation angle θ ranges from 90° to 190°. In this way, for the blade module 20 in the second position, where the trimming area 21A faces the body 10 such that at least a portion of the trimming area 21A is obscured by the body 10, the above-mentioned angle range is beneficial in two ways: firstly, it ensures that the trimming area 21A is fully exposed in the first position, facilitating user operation; secondly, it prevents the rotation angle of the blade module 20 from being too large, which would complicate the structure of the hair trimming device 100, thus reducing the manufacturing and design costs of the hair trimming device 100.

[0045] For example, when the blade module 20 is in the first position relative to the body 10, the trimming area 21A faces away from the body 10. This makes it more convenient for the user to use in the first position.

[0046] For example, when the cutter head module 20 is in the second position relative to the body 10, the trimming area 21A can be completely blocked by the body 10. In this way, the protective effect of the body 10 on the trimming area 21A can be improved in the second position.

[0047] For example, the maximum rotation angle θ of the blade module 20 between the second position and the first position ranges from 100° to 185°. In this way, for the blade module 20, which is covered by the body 10 when the outer surface of the blade mesh component 21 faces the body 10 in the second position, the aforementioned angle range helps to ensure that the blade mesh component 21 is fully exposed in the first position for user convenience. Furthermore, it prevents the rotation angle of the blade module 20 from becoming too large, which would complicate the structure of the hair trimming device 100, thus reducing the manufacturing and design costs of the hair trimming device 100.

[0048] For example, the maximum rotation angle θ of the cutter head module 20 between the second position and the first position is 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, 160°, 165°, 170°, 175°, 180° or 182°.

[0049] In some embodiments, please continue reading Figure 1 , Figure 2 and Figure 3 The body 10 includes a housing 11. The housing 11 is used to carry some functional components disposed inside the body 10, such as circuit boards and power batteries.

[0050] For example, the outer casing 11 extends along the arrangement direction of the body 10 and the blade module 20. That is, the length direction of the outer casing 11 is consistent with the arrangement direction of the body 10 and the blade module 20. This makes it easier for the user to hold the outer casing 11 to cut hair.

[0051] For example, the material of the housing 11 includes, but is not limited to, metal or plastic.

[0052] For example, please refer to Figure 3 In a plane perpendicular to the rotation axis O1, the vertical projection of the end of the outer shell 11 facing the cutter head module 20 is recessed in a direction away from the cutter head module 20. This provides clearance for the rotation of the cutter head module 20 relative to the body 10, avoids interference between the body 10 and the cutter head module 20 during rotation, and also improves the overall compactness of the cutter head module 20 and the body 10.

[0053] For example, the vertical projection of the end of the housing 11 facing the cutter head module 20 is a concave curve in the direction away from the cutter head module 20. In this way, while providing relief for the rotation of the cutter head module 20 relative to the body 10 and improving the overall compactness of the cutter head module 20 and the body 10, the structure of the housing 11 can be further optimized, making the structure of the housing 11 more aesthetically pleasing.

[0054] For example, the vertical projection of the end of the housing 11 toward the cutter head module 20 is one or more arc-shaped lines, one or more elliptical arc-shaped lines, or a combination of arc-shaped lines and elliptical arc-shaped lines.

[0055] This will help to further improve the reliability of the machine body 10 in avoiding the cutter head module 20, further improve the overall compactness of the cutter head module 20 and the machine body 10, and further optimize the structure of the outer shell 11, making the structure of the outer shell 11 more aesthetically pleasing.

[0056] For example, the center line of curvature of the curved vertical projection of the end of the housing 11 facing the cutter module 20 coincides with the rotation axis O1. For instance, when the vertical projection of the end of the housing 11 facing the cutter module 20 is an arc, the center line of that arc coincides with the rotation axis O1. This further improves the reliability of the housing 10 in avoiding the cutter module 20, further enhances the compactness of the overall structure of the cutter module 20 and the housing 10, and further optimizes the structure of the housing 11, making the structure of the housing 11 more aesthetically pleasing.

[0057] In some embodiments, please continue reading Figure 2 The wall panel at the end of the outer casing 11 facing the cutter head module 20 is a first wall panel 111. The first wall panel 111 is recessed into the outer casing 11 to define a clearance space for the cutter head module 20. In this way, the rotation of the cutter head module 20 relative to the body 10 can be avoided, preventing interference between the first wall panel 111 and the cutter head module 20 during rotation, and also improving the compactness of the overall structure of the cutter head module 20 and the body 10.

[0058] In some embodiments, when the blade module 20 is in the second position, the trimming area 21A faces the hygiene treatment module 12. This facilitates the blade mesh component 21, where the trimming area 21A is located, falling into the hygiene treatment area of ​​the hygiene treatment module 12, such as the sterilization area. The hygiene treatment module 12 can then perform hygiene treatment, such as sterilization, on the blade module 20 in the second position, thereby improving the hygiene treatment effect of the hygiene treatment module 12.

[0059] In some embodiments, please refer to Figure 4 , Figure 5 and Figure 6The hygiene treatment module 12 is located inside the outer casing 11 of the body 10. This allows the outer casing 11 to protect the hygiene treatment module 12. Of course, it is understood that in other embodiments, the hygiene treatment module 12 may also be located outside the outer casing 11, for example, the hygiene treatment module 12 may be located outside the outer casing 11 and mounted on the first wall panel 111 described above.

[0060] For example, the sanitation module 12 is located at one end of the housing 11 near the blade module 20. This allows the trimming area 21A to fall into the sanitation area of ​​the sanitation module 12, enabling thorough sanitation of the blade mesh component 21 in the second position, thereby improving the sanitation effect.

[0061] For example, the hygiene treatment module 12 includes a light source 122. For instance, the light emitted by this light source may include, but is not limited to, ultraviolet light, blue light, or infrared light. This results in good sterilization effect and low cost. In other embodiments, the hygiene treatment module 12 may be an ozone hygiene treatment module, a heating hygiene treatment module, or an alcohol hygiene treatment module, etc.

[0062] For example, when the sanitation module 12 includes a light source 122, please refer to [the relevant documentation]. Figure 5 The divergence angle γ of the light emitted from the light source 122 is greater than or equal to 60° and less than or equal to 180°. This ensures that the sterilization area of ​​the hygiene treatment module 12 is large, that the trimming area 21A is located within the sterilization area of ​​the hygiene treatment module 12, and also avoids affecting the structural layout of the internal structure of the machine body 10 due to an excessively large divergence angle γ.

[0063] For example, the divergence angle γ of the light emitted from the light source 122 is 65°, 70°, 75°, 80°, 85°, 90°, 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, 160°, 165°, 170°, or 175°.

[0064] For example, for the hygiene treatment module 12 located within the housing 11, when the hygiene treatment module 12 includes a light source 122, in order to facilitate the light emitted by the light source 122 to penetrate the housing 11 and illuminate the trimming area 21A, the end of the housing 11 facing the blade module 20 has a light-transmitting portion 112. This light-transmitting portion 112 is opposite to the hygiene treatment module 12. In this way, the hygiene treatment module 12 emits light towards the light-transmitting portion 112, and the light emitted by the hygiene treatment module 12 can pass through the light-transmitting portion 112 and illuminate the trimming area 21A, achieving the purpose of sterilization.

[0065] For example, please continue reading Figure 6 The wall panel at the end of the outer casing 11 facing the blade module 20 is a first wall panel 111. The first wall panel 111 has a through hole 1111. The light-transmitting part 112 is a light-transmitting solid component. The light-transmitting part 112 blocks the through hole 1111. In this way, not only can the light emitted by the sanitation treatment module 12 pass through the light-transmitting part 112 and illuminate the trimming area 21A, but the cooperation between the light-transmitting part 112 and the first wall panel 111 can also improve the sealing of the outer casing 11, thereby improving the waterproof and dustproof effect of the outer casing 11.

[0066] Of course, this application is not limited to this. In other embodiments, the light-transmitting portion 112 in the outer shell 11 can also be a light-transmitting through hole 1111.

[0067] For example, the shape of the through hole 1111 includes, but is not limited to, a circle, a rectangle, an ellipse, or an irregular shape.

[0068] For example, the material of the light-transmitting solid component can be quartz glass. Quartz glass has good light transmittance.

[0069] For example, please continue reading Figure 6 The housing 10 also includes a support frame 14. The support frame 14 is made of materials including, but not limited to, plastic, metal, and a combination of both. The support frame 14 is arranged laterally within the housing 11. The hygiene treatment module 12 is mounted on the support frame 14. Because the support frame 14 is arranged laterally within the housing 11, it is convenient to install the hygiene treatment module 12 in the laterally centered area inside the housing 11, thereby facilitating the relative arrangement of the hygiene treatment module 12 and the aforementioned light-transmitting portion 112.

[0070] For example, the connection between the support frame 14 and the housing 11 may include, but is not limited to, adhesive bonding, welding, snap-fitting, or screw connection.

[0071] It should be noted that "lateral arrangement" means that the circumferential direction of the support frame 14 is roughly the same as or consistent with the circumferential direction of the outer shell 11.

[0072] For example, please refer to Figure 6 and Figure 7 The fuselage 10 also includes a seal 13. The seal 13 is disposed around the through hole 1111. The seal 13 includes a first annular portion 131. The first annular portion 131 seals between the outer peripheral edge of the light-transmitting portion 112 and the first wall panel 111. In this way, the first annular portion 131 can be used to seal the gap between the first wall panel 111 and the light-transmitting portion 112, thereby improving the waterproof and dustproof performance of the fuselage 10.

[0073] For example, the material of the seal 13 includes, but is not limited to, rubber or silicone. This not only results in low cost but also good sealing performance.

[0074] For example, when the fuselage 10 includes a support frame 14, the support frame 14 is provided with an annular rib 141 extending toward the first wall panel 111. The annular rib 141 is arranged around the light-transmitting portion 112. The first annular portion 131 is also sealed between the annular rib 141 and the first wall panel 111. In this way, by utilizing the cooperation of the first annular portion 131 with the light-transmitting portion 112 and the annular rib 141 respectively, a two-stage sealing purpose can be achieved, thereby further improving the waterproof and dustproof effect of the fuselage 10.

[0075] For example, the support frame 14 and the annular rib 141 can be integrally formed. This simplifies the processing of the support frame 14 and the annular rib 141, reduces manufacturing costs, and improves the connection strength between them. In other examples, the support frame 14 and the annular rib 141 can also be connected by welding, gluing, snap-fitting, or screws.

[0076] For example, the first wall panel 111, which is recessed into the interior of the outer casing 11, is uneven. To facilitate the fit between the uneven first wall panel 111 and the seal 13, an annular stop flange 1112 is provided at the inner end of the through hole 1111. The inner surface of the first wall panel 111 has an annular stop rib 1113. The first annular portion 131 is sandwiched between the stop flange 1112 and the edge of the light-transmitting portion 112. The first annular portion 131 is also sandwiched between the stop rib 1113 and the annular rib 141.

[0077] For example, please continue reading Figure 6 The sanitation treatment module 12 includes a circuit board 121. The circuit board 121 is mounted on the support frame 14. A light source 122 is disposed on the surface of the circuit board 121 facing the light-transmitting portion 112.

[0078] For example, please continue reading Figure 6 and Figure 7 The light-transmitting portion 112 includes an edge light-transmitting portion 1121 and a central light-transmitting portion 1122. The edge light-transmitting portion 1121 is located on the outer periphery of the central light-transmitting portion 1122. A first annular portion 131 is located between the edge light-transmitting portion 1121 and the first wall panel 111. The central light-transmitting portion 1122 faces the light source 122 directly, and the entire central light-transmitting portion 1122 is recessed away from the light source 122 to define a clearance recess 1123. The formation of this clearance recess 1123 can be used to avoid the light source 122. This not only improves the structural compactness of the fuselage 10, but also avoids interference between the seal 13 and the sanitary treatment module 12 during assembly of the fuselage 10.

[0079] For example, to facilitate the assembly between the seal 13 and the light-transmitting portion 112, the seal 13 further includes a second annular portion 132. The second annular portion 132 is located on the side of the light-transmitting portion 112 opposite to the first annular portion 131. The outer peripheral edge of the second annular portion 132 is connected to the first annular portion 131, and the two cooperate to clamp the edge of the light-transmitting portion 112 (e.g., the aforementioned edge light-transmitting portion 1121). In this way, not only can the connection reliability between the seal 13 and the light-transmitting portion 112 be improved, but a secondary waterproof seal can also be formed between the light-transmitting portion 112 and the seal 13, resulting in a better sealing effect.

[0080] For example, the seal 13 can be a one-piece molded part, which helps to simplify the processing technology of the seal 13, reduce the manufacturing cost of the seal 13, and improve the connection reliability of the first annular portion 131 and the second annular portion 132.

[0081] For example, the sealing element 13 and the light-transmitting part 112 can be connected as a single unit using an in-mold secondary molding process. This improves the connection reliability between the sealing element 13 and the light-transmitting part 112, and enhances the sealing effect between them. Of course, this application is not limited to this; in other embodiments, the sealing element 13 and the light-transmitting part 112 can also be assembled together.

[0082] In some embodiments, please refer to Figure 8 and Figure 9 The outer casing 11 has two support members 15 extending towards the side where the cutter head module 20 is located, near one end of the outer casing 11. The two support members 15 are located at opposite ends of the outer casing 11. The cutter head module 20 is connected between the two support members 15. Specifically, since the two support members 15 extend towards the side where the cutter head module 20 is located, the two support members 15 protrude from the outer casing 11 towards the side where the cutter head module 20 is located. The area between the two support members 15 can form a placement space for the cutter head module 20. That is to say, the cutter head module 20 can be located between the two support members 15 and connected to the two support members 15, which is a simple structure.

[0083] For example, the two support members 15 are located at opposite ends of the housing 11 in the direction of extension of the rotation axis O1. The cutter head module 20 is rotatably connected to the two support members 15, so that when the cutter head module 20 rotates relative to the housing 10, interference of the housing 10 with the cutter head module 20 can be avoided, which helps to ensure the smooth rotation of the cutter head module 20.

[0084] For example, the connection between the support member 15 and the housing 11 may include, but is not limited to, adhesive bonding, welding, snap-fitting, or screw connection. In other examples, the support member 15 may also be integral with at least a portion of the housing 11.

[0085] Please continue reading. Figure 8 In some embodiments, the machine body 10 includes a first drive motor 16. The first drive motor 16 is connected to the cutter head module 20 and is used to drive the cutter head module 20 to rotate about the rotation axis O1.

[0086] Please continue reading. Figure 8 and Figure 9 When the cutter head module 20 is supported by the support member 15, the first drive motor 16 is installed on one of the support members 15. That is, the first drive motor 16 is installed on one support member 15 (i.e., the first support member 15A), and the first drive motor 16 is not installed on the other support member 15 (i.e., the second support member 15B).

[0087] In this example, by mounting the first drive motor 16 on the support 15, it is advantageous to place the first drive motor 16 and the cutter head module 20 relatively close together. This helps to avoid setting a transmission component for changing the power direction between the first drive motor 16 and the cutter head module 20, or to reduce the volume of the transmission component for changing the power direction between the first drive motor 16 and the cutter head module 20, thereby reducing the space occupied by the transmission component and improving the structural compactness of the hair trimming device 100.

[0088] For example, the rotation center axis of the first drive motor 16 is collinear with the rotation axis O1. In this way, it is not necessary to set up a transmission component for changing the power direction between the first drive motor 16 and the cutter head module 20, which helps to reduce the cost of the hair trimming device 100 and improve the structural compactness of the hair trimming device 100.

[0089] In other examples, the rotation center axis of the first drive motor 16 is parallel to the rotation axis O1, and the first drive motor 16 and the cutter head module 20 can be linked by transmission components such as gears or belts.

[0090] For example, please continue reading Figure 8 and Figure 9 The support member 15 for mounting the first drive motor 16, namely the first support member 15A, has a receiving cavity 151. This receiving cavity 151 is used to accommodate the first drive motor 16. In this way, the receiving cavity 151 can be used to protect the first drive motor 16.

[0091] For example, please continue reading Figure 8 and Figure 9 Each support member 15 includes a connecting plate 152 and a connecting block 153. The connecting plate 152 is connected to the housing 11. The connecting block 153 is located at the end of the connecting plate 152 away from the housing 11. The thickness of the connecting block 153 is greater than the thickness of the connecting plate 152.

[0092] The first support member 15A has a receiving cavity 151 in its connecting block 153, while the second support member 15B has a solid connecting block 153. Because the connecting block 153 is relatively thick, on the one hand, the receiving cavity 151 in the connecting block 153 of the first support member 15A provides ample installation space for the first drive motor 16; on the other hand, the solid connecting block 153 of the second support member 15B helps to balance the weight of the first drive motor 16 within the first support member 15A, reducing the weight difference between the first support member 15A and the first drive motor 16 as a whole, and between the first support member 15A and the second support member 15B, thus improving the consistency of support for the cutter head module 20 between the first support member 15A and the second support member 15B.

[0093] It is worth noting that in other embodiments, the first drive motor 16 can also be installed on each of the two support members 15. Furthermore, when both support members 15 are equipped with the first drive motor 16, both support members 15 can each have a receiving cavity 151, with each support member 15's receiving cavity 151 used to accommodate the corresponding first drive motor 16. Further, when the support member 15 includes a connecting block 153, the connecting blocks 153 of both support members 15 each have a receiving cavity 151 for accommodating the first drive motor 16, thereby achieving consistent support for the cutter head module 20 between the two support members 15.

[0094] For example, please continue reading Figure 8 ,and Figure 9 The first support member 15A has a shaft hole 15A1 communicating with the receiving cavity 151. This shaft hole 15A1 allows the motor shaft of the first drive motor 16, or a connecting shaft 161 connecting the motor shaft of the first drive motor 16 and the cutter head module 20, to pass through. (See also...) Figure 10 The cutter head module 20 (e.g., the mounting base 22 described below) has a protrusion 224 at one end facing the first support member 15A. The protrusion 224 has a rotating groove 2241. The shaft 161 is adapted to fit into the rotating groove 2241 and engages with the rotating groove 2241.

[0095] To improve the relative fixed connection between the shaft 161 and the rotating groove 2241 to facilitate the driving of the tool head module 20, the cross-section of the shaft 161 can be non-circular. For example, the shaft 161 can be rectangular, semi-circular, or elliptical.

[0096] For example, please continue reading Figure 8 and Figure 9 The second support member 15B is provided with a pivot groove 15B1. (See also...) Figure 10The end of the cutter head module 20 (e.g., the mounting base 22 described below) facing the second support member 15B is provided with a convex shaft 225. The convex shaft 225 is rotatably adapted within a pivot groove 15B1. Of course, in other embodiments, the convex shaft 225 is provided on the second support member 15B. The end of the cutter head module 20 (e.g., the mounting base 22 described below) facing the second support member 15B is provided with a pivot groove 15B1.

[0097] Considering the limited space on the support member 15 for arranging the first drive motor 16, the first drive motor 16 is, for example, an internal rotor brushless DC motor. It is small in size, powerful, and low in cost.

[0098] In some embodiments, please refer to Figure 10 and Figure 11 The cutter head module 20 includes a mounting base 22.

[0099] The mounting base 22 may be made of materials including, but not limited to, metal or plastic.

[0100] Mounting base 22 has an opening 226. The shape of the opening 226 includes, but is not limited to, rectangular, circular or irregular shapes.

[0101] The blade mesh component 21 is located at the opening 226.

[0102] For example, please continue reading Figure 11 The blade mesh component 21 includes one or more blade mesh structures 211. The illustration in the figure is based on the example of multiple blade mesh structures 211.

[0103] Each blade mesh structure 211 includes an inner blade mesh 2112 and an outer blade mesh 2111.

[0104] The inner blade 2112 can reciprocate relative to the mounting base 22. The inner blades 2112 of multiple blade structures 211 constitute the hair cutting assembly 211A (also referred to as the hair cutting assembly). It can be understood that when there is only one blade structure 211, the inner blade 2112 of that single blade structure 211 is the hair cutting assembly 211A.

[0105] The hair cutting component 211A can reciprocate relative to the mounting base 22.

[0106] For example, the swing center line of the inner blade 2112 may be parallel to the rotation axis O1.

[0107] Each outer blade mesh 2111 is located outside the corresponding inner blade mesh 2112. The outer blade meshes 2111 of the multiple blade mesh structures 211 constitute the outer blade mesh assembly 211B.

[0108] It is understandable that when there is only one blade mesh structure 211, the outer blade mesh 2111 of that single blade mesh structure 211 is the outer blade mesh component 211B.

[0109] As described above, the outer blade assembly 211B is located outside the hair cutting assembly 211A; conversely, the hair cutting assembly 211A is located inside the outer blade assembly 211B. The outer blade assembly 211B has the aforementioned trimming area 21A.

[0110] The hair cutting component 211A is movable relative to the outer blade assembly 211B, facilitating the cooperation between the hair cutting component 211A and the outer blade assembly 211B to cut hair, thereby achieving the purpose of hair cutting. Each outer blade 2111 slides against the mounting base 22, allowing the outer blade 2111 to rise and fall along the arrangement direction of the outer blade 2111 and the inner blade 2112. This allows the hair cutting component 211A to reciprocate and oscillate with the outer blade assembly 211B to cut hair, achieving the purpose of hair cutting, through the rising and falling of the outer blade 2111.

[0111] For example, each outer blade 2111 can be slidably plugged into the mounting base 22.

[0112] For example, the blade module 20 also includes a second drive motor 227. The second drive motor 227 is mounted within the mounting base 22. The second drive motor 227 is used to drive the hair cutting component 211A to reciprocate. In this way, integrating the second drive motor 227 within the mounting base 22 makes it easier for the second drive motor 227 to drive the hair cutting component 211A, and the structure is compact.

[0113] For example, to enable the second drive motor 227 to drive the hair cutting component 211A to swing, the cutter module 20 may further include a swing frame 25 and an eccentric wheel 24. The second drive motor 227 is connected to the eccentric wheel 24. The eccentric wheel 24 is connected to the swing frame 25. The swing frame 25 is connected to the hair cutting component 211A. When the second drive motor 227 rotates, it can drive the eccentric wheel 24 to rotate. The rotation of the eccentric wheel 24 drives the swing frame 25 to swing back and forth. The swing of the swing frame 25 can drive the hair cutting component 211A to swing.

[0114] The specific structure and connection method of the eccentric wheel 24, the swing frame 25, and the hair cutting assembly 211A are well known to those skilled in the art and will not be described in detail here.

[0115] For example, the second drive motor 227 is an external rotor brushless motor, which has low noise and long life.

[0116] For example, the cutter head module 20 may also include a mounting bracket 23. The mounting bracket 23 is mounted within the mounting base 22. The connection between the mounting bracket 23 and the mounting base 22 includes, but is not limited to, adhesive bonding, welding, snap-fitting, or screw connection. The swing bracket 25 is mounted on the mounting bracket 23. The connection method between the swing bracket 25 and the mounting bracket 23 is well known to those skilled in the art and will not be described in detail here.

[0117] Based on this, for example, the second drive motor 227 is mounted on the mounting bracket 23 and is located on the side of the mounting bracket 23 opposite to the opening. The second drive motor 227 can be mounted on the mounting bracket 23 originally used to mount the swing bracket 25, without the need for a separate mounting structure, which helps to reduce costs.

[0118] For example, the connection between the second drive motor 227 and the mounting bracket 23 may include, but is not limited to, adhesive bonding, welding, snap-fitting, or screw connection.

[0119] In some embodiments, please continue reading Figure 10 , Figure 11 And return to refer to them together. Figure 2 The mounting base 22 includes a first side plate 221, a second side plate 222, and an arc-shaped plate 223.

[0120] The first side plate 221 and the second side plate 222 are arranged opposite to each other and spaced apart in the extension direction of the rotation axis O1. An arc-shaped plate 223 is connected between the edges of the first side plate 221 and the second side plate 222. The center line of the arc-shaped plate 223 is parallel or collinear with the rotation axis O1; the cutter head module 20 is rotatably connected to the machine body 10 by means of the first side plate 221 and the second side plate 222.

[0121] In this way, when the blade module 20 rotates relative to the body 10, it helps to reduce the space required for the blade module 20 to rotate, thereby improving the structural compactness of the hair trimming device 100.

[0122] For example, the first side panel 221 can be fan-shaped, semi-circular, or semi-circular. The second side panel 222 can be fan-shaped, semi-circular, or semi-circular.

[0123] For example, please continue reading Figure 11 The inner surface of the arc-shaped plate 223 is recessed with a clearance step 2231. The clearance step 2231 is used to avoid the second drive motor 227. This helps to improve the structural compactness of the cutter head module 20.

[0124] In some embodiments, please refer to Figure 12The machine body 10 may include an instruction detection structure 19. The instruction detection structure 19 is used to acquire a second switching instruction. The second switching instruction is used to instruct the cutter head module 20 to switch from a second position to a first position.

[0125] The chassis 10 may also include a control module 18. For example, the control module 18 may be integrated on a circuit board. The control module 18 may include, but is not limited to, a processor.

[0126] The control module 18 is electrically connected to both the command detection structure 19 and the first drive motor 16. After receiving a second switching command from the command detection structure 19, the control module 18 controls the first drive motor 16 to operate, thereby using the first drive motor 16 to drive the cutter head module 20 to switch from the second position to the first position.

[0127] This makes the hair trimming device 100 more technologically advanced and provides a better user experience.

[0128] For example, the material constituting the housing 11 includes conductive particles (not shown). The control module 18 is electrically connected to the conductive particles.

[0129] The conductive particles include, but are not limited to, metal particles, indium tin oxide (ITO) particles, silver nanowires, or conductive polymer particles.

[0130] For example, the housing 11 may include a resin matrix, which includes, but is not limited to, thermosetting resin and thermoplastic resin. Conductive particles are uniformly distributed within the resin matrix. This results in low processing cost and light weight for the housing 11.

[0131] For example, the instruction detection structure 19 includes a housing 11. For the housing 11 made of conductive particles, when a user touches the housing 11, a microcurrent is formed between the skin surface and the conductive particles. The control module 18 can then receive this microcurrent signal, which can be used as a second switching instruction. After receiving this microcurrent signal, the control module 18 can control the blade module 20 to switch from a second position to a first position, making the hair trimming device 100 more technologically advanced and providing a better user experience.

[0132] For example, the body 10 includes a motion sensor (not shown). The motion sensor may be integrated onto a circuit board. The motion sensor is used to detect changes in the posture of the hair trimming device 100.

[0133] For example, the motion sensor can be a gyroscope sensor. The gyroscope sensor can be used to determine the motion posture of the hair trimming device 100. For example, the angular velocity of the hair trimming device 100 about three axes (i.e., the x, y, and z axes) can be determined by the gyroscope sensor.

[0134] The instruction detection structure 19 may include a motion sensor. When a user picks up the hair trimmer 100, the motion sensor can detect a change in the posture of the hair trimmer 100. In this way, the control module 18 can receive this posture change signal, which can be used as a second switching command. Therefore, after receiving this posture change signal, the control module 18 can control the blade module 20 to switch from a second position to a first position, making the hair trimmer 100 more technologically advanced and providing a better user experience.

[0135] Specifically, the instruction detection structure 19 can simultaneously include the aforementioned shell 11 with conductive particles and the motion sensor. In this way, after the control module 18 receives the aforementioned micro-current signal and attitude change signal, it uses both signals as a second switching instruction. This allows the control module 18 to control the blade module 20 to switch from the second position to the first position after receiving the second switching instruction. This enhances the technological feel of the hair trimming device 100, improves the user experience, and facilitates precise control of the hair trimming device 100 by the control module 18 based on the user's actual needs. It also avoids the problem of position switching of the blade module 20 caused by attitude changes in the hair trimming device 100 due to external objects touching it.

[0136] For example, please refer to Figure 12 And return them together Figure 1 and Figure 2 The device body 10 also includes a power switch 17. The power switch 17 is located on the outer casing 11. The power switch 17 includes, but is not limited to, touch buttons and mechanical buttons.

[0137] The on / off switch 17 is used to output hair cutting commands and cutting task completion commands triggered by the user. The control module 18 can be electrically connected to both the second drive motor 227 and the on / off switch 17.

[0138] Specifically, during the user's use of the hair trimming device 100, when the user triggers the power switch 17, the power switch 17 outputs a hair-cutting command to the control module 18. After receiving this hair-cutting command, the control module 18 controls the second drive motor 227 to drive the hair cutting component 211A to perform cutting motion. When the user triggers the power switch 17 again, the power switch 17 outputs a cutting task end command to the control module 18, and the control module 18 controls the second drive motor 227 to stop.

[0139] After the second drive motor 227 stops, the control module 18 can control the first drive motor 16 to drive the blade module 20 from the first position to the second position. This allows the hair trimming device 100 to be more intelligent and technologically advanced when the user is not using it, thanks to the protection of the blade mesh component 21 provided by the body 10. For example, to ensure the safety of using the hair trimming device 100, after the control module 18 controls the second drive motor 227 to stop for a first preset time, the control module 18 controls the first drive motor 16 to drive the blade module 20 from the first position to the second position.

[0140] For example, the first preset duration can be in the range of 1 second to 10 seconds. For instance, the first preset duration can be 2 seconds, 3 seconds, 4 seconds, 5 seconds, 6 seconds, 7 seconds, 8 seconds, or 9 seconds.

[0141] In other embodiments, the control module 18 may also control the first drive motor 16 to drive the cutter head module 20 to switch from the first position to the second position immediately after controlling the second drive motor 227 to stop.

[0142] For example, when the hair trimming device 100 does not include the instruction detection structure 19 described above, the switch 17 can serve as a medium for obtaining the second switching instruction. In this case, triggered by the user, the switch 17 will simultaneously output the second switching instruction and the hair cutting instruction to the control module 18.

[0143] For example, the control module 18 can be electrically connected to the hygiene treatment module 1. After the control module 18 controls the first drive motor 16 to drive the blade module 20 from the first position to the second position, the control module 18 controls the first drive motor 16 to stop and controls the hygiene treatment module 12 to work. In this way, not only is timely sterilization of the blade module 20 facilitated, but it also helps to improve the technological feel of the hair trimming device 100 and enhance the user experience.

[0144] In some embodiments, the housing 10 has a first limiting structure (not shown). For example, the housing 11 has a first limiting structure at one end near the cutter head module 20, and the first limiting structure protrudes from the housing 11. Alternatively, the first limiting structure may also be provided within the aforementioned pivot groove 15B1.

[0145] The first limiting structure is used to cooperate with the cutter head module 20 when the cutter head module 20 is in the second position, so as to limit the cutter head module 20 from continuing to rotate in the direction from the first position to the second position. In this way, the setting of the first limiting structure can avoid the excessive rotation of the cutter head module 20 under the drive of the first drive motor 16, which helps to ensure that the cutter head module 20 is maintained in the second position.

[0146] Specifically, after the first drive motor 16 drives the blade module 20 to switch to the second position, the first drive motor 16 generates a stall signal due to the restriction of the first limiting structure. Upon receiving the stall signal from the first drive motor 16, the control module 18 controls the first drive motor 16 to stop and controls the sanitation module 12 to operate. This not only facilitates timely sterilization of the blade module 20 but also enhances the technological feel of the hair trimming device 100 and improves the user experience.

[0147] For example, after receiving a stall signal from the first drive motor 16, the control module 18 controls the first drive motor 16 to stop for a second preset time, and then controls the sanitation treatment module 12 to work.

[0148] For example, the second preset duration can be in the range of 1 second to 10 seconds. For instance, the second preset duration can be 2 seconds, 3 seconds, 4 seconds, 5 seconds, 6 seconds, 7 seconds, 8 seconds, or 9 seconds.

[0149] In other embodiments, the control module 18 may also simultaneously control the first drive motor 16 to stop and control the sanitation treatment module 12 to operate.

[0150] In some embodiments of this application, the hair trimming device 100 further includes a weightlessness detection device 50. The weightlessness detection device 50 is used to detect whether the hair trimming device 100 is in free fall motion. For example, the weightlessness detection device 50 is an accelerometer, a microgravity sensor, or an inertial measurement unit (IMU), that is, an accelerometer and a gyroscope / magnetometer.

[0151] The control module 18 can be electrically connected to the weightlessness detection device 50. When the weightlessness detection device 50 detects that the hair trimming device 100 is in free fall, it controls the blade assembly 21 to switch to the second position. This prevents the blade assembly 21 from falling and being damaged.

[0152] In some embodiments of this application, please refer to Figure 16 The hair trimming device 100 also includes a protective cover 30. The protective cover 30 is detachably fitted to the body 10 to cover the blade module 20. In this way, the protective cover 30 can further protect the blade module 20 and improve the reliability of the protection of the blade module 20.

[0153] For example, when the hygiene treatment module 12 includes a light source 122 for emitting ultraviolet rays, the material of the protective cover 30 can be an ultraviolet-resistant material, so as to prevent ultraviolet rays from being exposed and improve the hygiene treatment effect of the hygiene treatment module 12 on the blade mesh component 21.

[0154] For example, the protective cover 30 can be made of plastic, such as polycarbonate (PC), polytetrafluoroethylene, etc.

[0155] In other embodiments, an anti-ultraviolet layer may be provided on the inner surface of the protective cover 30. This prevents ultraviolet radiation from being exposed and improves the hygienic treatment effect of the hygienic treatment module 12 on the blade mesh component 21.

[0156] The control method for the hair trimming device described above will be explained below. Please refer to [link / reference]. Figure 13 The control method for the hair trimming device includes:

[0157] S10: Receive a first switching command for the blade / net component. For example, the first switching command is generated when it is detected that the blade / net component has stopped performing the cutting action. Another example is when it is detected that the hair trimming device is in free fall. Yet another example is when a user's preset operation is detected, the first switching command is generated. For instance, the user's preset operation could be the user triggering a power button. Yet another example is that the hair trimming device can wirelessly communicate with the user's mobile terminal (e.g., a mobile phone or tablet). The user's preset operation could be the user triggering the hair trimming device's app on the mobile terminal's interface, and the mobile terminal then sends the first switching command to the hair trimming device.

[0158] S20: Control the blade assembly to switch from the first position to the second position. For example, the control module can control the first drive motor to drive the blade module to switch from the first position to the second position.

[0159] In this way, when the first switching command is received, the blade and net component can be controlled to switch from the first position to the second position where at least part of the trimming area is covered by the machine body. The machine body's covering of the trimming area serves to protect the blade and net component. Compared with related technologies, the protective cover can be omitted, reducing the cost of the hair trimming device and avoiding the problem of the protective cover falling off or being lost, which is conducive to improving the user experience.

[0160] Please refer to some embodiments of this application. Figure 13 After the control blade component switches from the first position to the second position, that is, after step S20, the control method of the hair trimming device further includes:

[0161] S30: Control the operation of the hygiene treatment module. For example, the hygiene treatment module can be a sterilization module, thereby facilitating the control of the sterilization module to sterilize the blade mesh components.

[0162] This makes it easier to clean the blade and mesh components, and also helps to enhance the technological feel of the hair trimming device and improve the user experience.

[0163] In some embodiments of this application, please refer to Figure 14 Prior to receiving the first switching command for the blade foil component, the control method for the hair trimming device further includes:

[0164] S1: In response to receiving a second switching command.

[0165] S2: Control the blade mesh component to switch from the second position to the first position.

[0166] In this way, when the user needs to use the hair trimming device, the blade and foil components can be controlled to be in the first exposed position of the trimming area to facilitate the hair cutting function, which helps to improve the user experience.

[0167] In some embodiments, the second switching command instructs the user to pick up the hair trimmer, that is, the second switching command instructs a change in the posture of the hair trimmer. Alternatively, it can be understood that the second switching command is generated when a change in the posture of the hair trimmer is detected. For example, the second switching command can be acquired using the aforementioned housing with conductive particles and / or a motion sensor. This enhances the technological feel of the hair trimmer and improves the user experience.

[0168] In some embodiments, please refer to Figure 15 If the hair trimming device receives a hair-cutting command, the control method for the hair trimming device further includes the following after the blade and foil components switch to the first position:

[0169] S3: Controls the hair cutting component to perform the cutting action.

[0170] For example, the hair-cutting command can be issued along with the second switching command. That is, the hair-cutting command is issued simultaneously with the second switching command. For instance, the aforementioned power switch, triggered by the user, can issue both the hair-cutting command and the second switching command together. Alternatively, the hair trimming device can receive a user's voice command to instruct hair cutting. After receiving the user's voice command, the hair trimming device issues the hair-cutting command and the second switching command together. Furthermore, the hair trimming device can wirelessly communicate with the user's mobile terminal (e.g., a mobile phone or tablet). The user can trigger the hair trimming device's app on the mobile terminal's interface, and the mobile terminal then sends the hair-cutting command and the second switching command to the hair trimming device.

[0171] For example, the hair-cutting command can be sent either during the switching process of the blade component from the second position to the first position, or after the blade component has switched to the first position. For instance, a user triggers a power button to issue a hair-cutting command; or, the hair trimming device can receive a user's voice-activated cutting command, which instructs the user to cut the hair, and the cutting command is issued after the hair trimming device receives the user's voice-activated cutting command. Furthermore, the hair trimming device can wirelessly communicate with a user's mobile terminal (e.g., a mobile phone or tablet). The user can trigger the hair trimming device's app on the mobile terminal's interface, and the mobile terminal then sends a hair-cutting command to the hair trimming device.

[0172] In some embodiments, prior to receiving a first switching command for the blade reamer component, the control method further includes:

[0173] S4: Controls the hair cutting component to stop cutting.

[0174] After the hair cutting component stops cutting, the first switching command mentioned above can be received. For example, after a first preset time has elapsed since the hair cutting component stopped cutting, step S20 is executed: the blade mesh component is switched from the first position to the second position. This ensures the safety of using the hair trimming device.

[0175] For example, the first preset duration can be in the range of 1 second to 10 seconds. For instance, the first preset duration can be 2 seconds, 3 seconds, 4 seconds, 5 seconds, 6 seconds, 7 seconds, 8 seconds, or 9 seconds.

[0176] In some embodiments, please continue reading Figure 15 The control method for the hair trimming device, which involves switching the control blade component from the first position to the second position (i.e., after step S20 and before step S30), includes:

[0177] S21: Receive the stall signal of the first drive motor.

[0178] In step S30, the first drive motor is stopped, and the sanitation treatment module is put into operation.

[0179] In this way, the control module can use the stall signal of the first drive motor to control the first drive motor to stop, and control the sanitation treatment module to stop. This not only facilitates timely sterilization of the trimming area, but also helps to improve the technological feel of the hair trimming device and enhance the user experience.

[0180] For example, in the step of controlling the first drive motor to stop and controlling the sanitation treatment module to work, that is, in step S30, after controlling the first drive motor 16 to stop for a second preset time, the sanitation treatment module 12 is controlled to work.

[0181] For example, the second preset duration can be in the range of 1 second to 10 seconds. For instance, the second preset duration can be 2 seconds, 3 seconds, 4 seconds, 5 seconds, 6 seconds, 7 seconds, 8 seconds, or 9 seconds.

[0182] In other embodiments, the first drive motor 16 can be stopped and the sanitation treatment module 12 can be operated simultaneously.

[0183] In some embodiments, please continue reading Figure 15 After controlling the first drive motor to stop and controlling the hygiene treatment module to work in step S30, the control method for the hair trimming device further includes:

[0184] S40: Control the sanitation treatment module to stop working.

[0185] This makes it easier to save electricity used by hair trimming devices.

[0186] For example, in step S40, after the sanitation treatment module has been working continuously for a third preset period of time, the sanitation treatment module is controlled to stop working.

[0187] For example, the third preset duration can be from 5 seconds to 200 seconds. For instance, the third preset duration can be 10 seconds, 20 seconds, 30 seconds, 40 seconds, 50 seconds, 60 seconds, 70 seconds, 80 seconds, 90 seconds, 100 seconds, 110 seconds, 120 seconds, 130 seconds, 140 seconds, 150 seconds, 160 seconds, 170 seconds, 180 seconds, or 190 seconds.
