[0033] The core of this utility model is to provide a stepless speed-regulating hair clipper, which adopts a stepless speed regulation method to meet the usage needs of hair clippers in different environments and improve the user experience of hair clippers.

[0034] Please refer to Figure 5 A continuously variable speed hair clipper includes a housing 1, a speed regulating component 6, a blade assembly 2, a connecting frame 12, and an eccentric wheel 10. The housing 1 houses a control board 5, a motor 3, and a power supply 4. The speed regulating component 6 is used to continuously adjust the speed of the motor 3. The blade assembly 2 optionally includes a stationary blade support 202. The blade assembly 2 includes a stationary blade 201, a movable blade 203 that slides in contact with the stationary blade 201, and a drive unit 204 connected to the movable blade 203.

[0035] It should be noted that in this embodiment of the present invention, the motor 3 can be a small motor as the driving source, and the battery can be a rechargeable battery, and a charging port is provided on the control board 5.

[0036] In addition, in this embodiment of the present invention, both the moving blade 203 and the stationary blade 201 have a serrated structure and are made of metal.

[0037] In addition, in this embodiment of the invention, the contact surfaces of the moving blade 203 and the stationary blade 201 are coated with a wear-resistant layer or made of a wear-resistant material.

[0038] Optionally, in some embodiments, the drive unit 204 is slidably mounted inside the housing 1. Specifically, the housing 1 is provided with a sliding groove, through which the drive unit 204 slides smoothly within the housing 1.

[0039] In use, the control board 5, motor 3, and power supply 4 are all installed inside the housing 1. The speed control component 6 enables stepless adjustment of the motor 3. The motor 3 controls the relative sliding between the moving blade 203 and the stationary blade 201. At the same time, the moving blade 203 and the stationary blade 201 come into contact, thus achieving the shearing effect. The adjustment component 7 also adjusts the overlap length of the stationary blade 201 and the moving blade 203, allowing for rapid adjustment for different trimming situations to meet the user's needs. The stepless adjustment of the speed control component 6 allows for arbitrary speed adjustment according to different trimming lengths or trimming situations, effectively increasing the user's choice of product power and enhancing the user's comfort and convenience.

[0040] Please refer to Figure 6 In some embodiments, the stationary blade 201 is mounted on the housing 1, that is, the stationary blade 201 can be directly mounted on the housing 1 by bolt fixing.

[0041] Please refer to Figure 1 In some embodiments, the blade assembly 2 further includes a stationary blade bracket 202 for fixing the stationary blade 201. The stationary blade bracket 202 is connected to the housing 1, and the stationary blade 201 can be installed and fixed by means of the stationary blade bracket 202.

[0042] Optionally, in some embodiments, the stationary blade 201 can be fixed to the stationary blade bracket 202 by bolts. Specifically, the stationary blade 201 has a through hole, and the stationary blade bracket 202 has a corresponding threaded hole. The stationary blade 201 is fixed by bolts. The stationary blade bracket 202 includes a connecting part, which is a snap-fit ​​structure with two L-shaped structures. The outer shell 1 has a slot for fixing the connecting part. Therefore, the connecting part can be fixed to the outer shell 1 through the slot, so that the stationary blade bracket 202 can be fixed to the outer shell 1.

[0043] Please refer to Figure 1In some embodiments, the outer shell 1 includes an upper shell 101 and a lower shell 102, with the upper shell 101 and the lower shell 102 forming an installation cavity. The control board 5, the motor 3, the power supply 4, and the speed control component 6 are all placed in the installation cavity. The speed control component 6 includes a control switch 601 mounted on the control board 5 and a speed control switch 603 for stepless adjustment. The upper shell 101 is provided with an opening for the speed control switch 603 to extend out of the installation cavity. In other words, the opening and closing of the hair clippers can be controlled by the control switch 601.

[0044] Optionally, in some embodiments, the upper housing 101 is further provided with an opening for the control switch 601 to extend out of the upper housing 101, so as to facilitate operation by the user.

[0045] Optionally, in some embodiments, the upper shell 101 and the lower shell 102 are detachably connected by means of snaps or bolts to facilitate their assembly and maintenance.

[0046] In the above embodiment, the lower shell 102 is provided with a number of limiting grooves, limiting posts, positioning posts and other structures. The control plate 5 is fixed in position by a number of positioning posts. At the same time, the positioning posts are provided with threaded holes, and the control plate 5 is provided with through holes corresponding to the positions of the positioning posts. Therefore, the control plate 5 can be fixed in the outer shell 1 by bolts. Meanwhile, the power supply 4 is a lithium battery, and the battery is fixed by the fixing groove of the lower shell 102.

[0047] Please refer to Figure 1 In some embodiments, the speed control component 6 further includes an encoder 604, which is electrically connected to the control board 5. The speed control switch 603 is connected to the encoder 604. That is, by connecting the encoder 604 and the motor 3, stepless speed regulation of the motor 3 can be achieved.

[0048] Optionally, in some embodiments, the encoder 604 can be directly fixed to the control board 5, that is, installed on the control board 5 in an integrated manner. The encoder 604 provides crucial real-time feedback for the motor 3 control system by converting mechanical motion into electrical signals. At the same time, the controller uses this feedback to compare and correct with the target command, thereby realizing high-precision and high-dynamic response control of the motor 3 speed and position, and also realizing stepless adjustment of the electrode speed.

[0049] Please refer to Figure 1In some embodiments, the speed control switch 603 is a roller component, which is rotatably mounted on the control plate 5. A speed control lever 605, coaxially aligned with the roller component, is provided on one side of the roller component. The speed control lever 605 is connected to the encoder 604. In other words, by adopting a roller component structure, the user can easily control the speed of the motor 3 by simply flicking the lever, and the user can also have a more specific feel for speed adjustment. The speed control lever 605, coaxially aligned with the roller component, is provided on one side of the roller component. The speed control lever 605 is then connected to the encoder 604. Specifically, the speed control lever 605 is inserted into the encoder 604, and the user can control the rotation of the motor 3 by rotating the roller component, which is more convenient and faster.

[0050] Optionally, in some embodiments, in order to further improve the control of the encoder 604, the speed control lever 605 adopts an irregular shape. Specifically, the speed control lever 605 is provided with a cutout with a semi-circular cross-section, and the encoder 604 can be controlled more precisely through the cutout.

[0051] Optionally, in some embodiments, the control plate 5 is provided with at least one support protrusion, and the roller is rotatably mounted on the control plate 5 through the support protrusion. Specifically, the speed control lever 605 passes through the support protrusion and rotatably engages with the support protrusion.

[0052] Please refer to Figure 1 In some embodiments, a switch control lever 602 is provided on the side of the roller component away from the speed control lever 605, and is coaxially arranged with the roller component. The switch control lever 602 is in contact with the control switch 601. That is to say, in order to reduce the number of switch buttons, the control switch 601 and the speed control switch 603 are integrated and cooperated. Specifically, the switch control lever 602 is coaxially arranged on the roller component and is positioned above the control switch 601. Therefore, the user can control the opening and closing of the hair clippers by pressing the speed control switch 603, which is more convenient and faster, and reduces exposed buttons, improving the aesthetics of the hair clippers.

[0053] Optionally, in some embodiments, both the speed control lever 605 and the switch control lever 602 are made of materials with elastic deformation, such as PVC, PE, etc.

[0054] Optionally, in some embodiments, the control lever switch may be a micro-push switch to increase the sensitivity of the control switch 601.

[0055] Optionally, in some embodiments, the control switch 601 is provided with a groove for fixing the switch control lever 602. Specifically, the button of the control switch 601 is provided with a top sleeve with a groove, which can place the switch control lever 602 inside the groove, so that the switch control lever 602 is more stable when rotating, and at the same time ensures that the switch control lever 602 is always in contact with the control switch 601, thereby increasing the stability of use.

[0056] Optionally, in some embodiments, to ensure that the speed control switch 603 has sufficient rebound, a reset member can be installed on the control board 5, and the reset member contacts the top sleeve of the above embodiment, so that the speed control switch 603 quickly resets after pressing, ensuring that the control switch 601 is reset.

[0057] Optionally, in some embodiments, the roller is provided with anti-slip texture, which helps to increase the stability of the roller during sliding; or, a rubber layer is used instead of anti-slip texture.

[0058] Optionally, in some embodiments, the axis of the speed control lever 605 is arranged perpendicular to the length direction of the housing 1 to limit the orientation of the roller, making the speed control switch 603 easier for the user to operate and allowing the user to easily toggle the speed control switch 603 with one hand.

[0059] Please refer to Figure 1 In some embodiments, a support plate 8 is also fixed inside the mounting cavity, and a rotating shaft 9 is rotatably mounted on the support plate 8. One end of the rotating shaft 9 is connected to the output end of the motor 3, and an eccentric wheel 10 is fixed to the other end of the rotating shaft 9. The eccentric wheel 10 is used to connect with the drive unit 204. That is to say, the stability of the rotating shaft 9 during rotation is increased by the support plate 8, thereby increasing the stability of the moving blade 203 during use.

[0060] Optionally, in some embodiments, a bearing is mounted on the support plate 8, and the smoothness of rotation of the shaft 9 is increased by passing the shaft 9 through the bearing.

[0061] Optionally, in some embodiments, a connecting rod 11 is eccentrically mounted on the eccentric wheel 10, and the connecting rod 11 is connected to the drive unit 204. That is, the movement of the moving blade 203 is controlled by the eccentric wheel.

[0062] Optionally, in some embodiments, the drive unit 204 includes a connecting plate and a connecting groove provided on the connecting plate. The connecting rod 11 is inserted into the connecting groove, and the width of the connecting groove is the same as the diameter of the connecting rod 11. Therefore, when the motor 3 rotates, it drives the drive unit 204 to move.

[0063] Please refer to Figure 1In some embodiments, the adjustment component 7 includes an adjustment arm 702 and a locking block 701. One end of the adjustment arm 702 is hinged to the housing 1. The adjustment arm 702 is connected to the stationary blade support 202. The housing 1 is provided with a plurality of positioning grooves 703 that cooperate with the locking block 701. That is to say, the position of the stationary blade 201 is adjusted by adjusting the adjustment arm 702, thereby realizing the control of the overlap length of the stationary blade 201 and the moving blade 203, which is more convenient and faster.

[0064] Optionally, in some embodiments, the stationary blade holder 202 is slidably mounted on the housing 1, and the stationary blade holder 202 is provided with a movable slot. The adjusting arm 702 is provided with a protrusion that cooperates with the movable slot. After the protrusion is inserted into the movable slot, the adjusting arm 702 can be rotated to control the stationary blade holder 202 to slide on the housing 1, thereby controlling the overlap length of the stationary blade 201 and the moving blade 203.

[0065] Optionally, in some embodiments, the outer casing 1 is provided with an arc-shaped limiting hole concentric with the rotation axis of the adjusting arm 702. The limiting hole is composed of several evenly distributed through holes. When the locking block 701 enters the through hole, the position of the adjusting arm 702 can be fixed.

[0066] Optionally, in some embodiments, the blade assembly 2 further includes a temperature control device that contacts the stationary blade 201. The temperature control device is electrically connected to the control board 5. The temperature control device uses a thermoelectric cooler, also known as a Peltier element, which is a device that uses the thermoelectric effect to achieve cooling or heating. When current passes through the thermoelectric cooler, the movement of electrons between the P-type and N-type materials leads to heat transfer. Specifically, the current causes electrons to accumulate in the P-type material and decrease in the N-type material. This change in electron density causes a redistribution of heat, resulting in heat generation on one side of the thermoelectric cooler (hot end) and heat absorption on the other side (cold end). Therefore, both sides of the thermoelectric cooler generate heat, but the temperature of the hot end is higher and the temperature of the cold end is lower. Thus, using a thermoelectric cooler can achieve both heating and cooling.

[0067] Optionally, in some embodiments, the blade assembly 2 further includes a heat sink, which contacts the side of the thermoelectric cooler away from the stationary blade 201 and is fixedly connected to the connecting frame (12). In other words, the heat sink can quickly dissipate the heat at the hot end of the thermoelectric cooler during use to ensure the cooling effect of the thermoelectric cooler.

[0068] Optionally, in some embodiments, in order to improve the heat dissipation effect of the heat sink, a number of heat dissipation openings can be provided on the stationary knife bracket 202 or the housing 1 during installation, and the heat sink can be made to contact the outside through the heat dissipation openings to improve its heat dissipation efficiency.

[0069] Optionally, in some embodiments, the blade assembly 2 further includes a heat insulation sheet located between the stationary blade support 202 and the heat sink. The function of the heat insulation sheet is to isolate the heat sink from the stationary blade support 202, so as to avoid the heat sink from contacting the stationary blade support 202 and causing the cooling effect of the stationary blade 201 to deteriorate, thereby improving the performance of the stationary blade 201.

[0070] In other words, the key features of this invention are: the control board 5, motor 3, and power supply 4 are all installed inside the housing 1, and the stepless adjustment of the motor 3 is achieved through the speed regulating component 6. The motor 3 controls the relative sliding between the moving blade 203 and the stationary blade 201, and at the same time, the moving blade 203 and the stationary blade 201 come into contact, thus achieving the shearing effect. In addition, the overlap length of the stationary blade 201 and the moving blade 203 is adjusted through the adjusting component 7, so that it can be quickly adjusted for different trimming situations to meet the needs of users. The stepless adjustment effect of the speed regulating component 6 can adjust the speed arbitrarily according to different trimming lengths or trimming situations, which can effectively increase the user's choice of product power and increase the user's comfort and convenience in using the product.

[0071] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
