Description

Technical Field

[0001] The present invention relates to the technical field of hair removal devices, and more particularly to a hair clamping component and a hair remover. Background Art

[0002] The hair clip assembly is a personal care device for plucking human hair. It usually uses the clamping effect of multiple clips connected in series on an arched shaft to grasp and release the hair. When the clip rotates to the narrower side of the arched shaft, a clamping effect is generated to grasp the hair; and when it rotates to the wider side of the arched shaft, the hair is released.

[0003] For example, CN201079113Y discloses an electric hair remover, comprising a disc, a crankshaft and a driven gear; wherein the disc and the disc rack are alternately inserted on the crankshaft to form a disc group; the surface of the disc has a ring array of alternately arranged protrusions and recesses.

[0004] In the above patented structure, as the device runs for a long time, a jamming phenomenon may occur due to continuous friction between the disc racks and the outer shell on both sides of the hair clamping assembly. Summary of the invention

[0005] The present invention aims to solve one of the technical problems in the related art to a certain extent. To this end, the present invention proposes a hair clamping component, which realizes dynamic buffering and support through a combination of elastic balls and ordinary balls, reduces local friction, improves the stability and durability of the hair clamping component, and improves user experience.

[0006] The invention also provides an epilator having the hair clamping assembly.

[0007] The technical solution adopted by the present invention is to provide a hair clamping component, including: Base; A movable seat rotatably mounted on one side of the base; A driven gear, a transmission gear, a plurality of clips and a plurality of mounting seats, wherein the clips and the mounting seats are arranged alternately, the driven gear and the transmission gear are arranged on both sides of the plurality of mounting seats and are connected in series through an arched shaft, and the two ends of the arched shaft are respectively connected to the base and the movable seat; Among them, the inner surface of the movable seat is provided with multiple first balls and multiple second balls, the first balls are elastic balls, and the first balls are located on the narrower side of the bow-shaped axis, and the second balls are located on the wider side of the bow-shaped axis. When the outer side of the driven gear or the transmission gear is pushed to abut against the first ball, the diameter of the first ball is elastically reduced and remains in a rollable state.

[0008] Since the first ball is located on the narrowing side of the bow shaft, it is subjected to a greater extrusion force. Under different working conditions, the number and thickness of hair clamped by multiple clips are different, resulting in a dynamic change in the reaction force between the clips and the mounting seat. This force is further transmitted to the movable seat and the driven gear or the transmission gear, causing the local friction to gradually increase, which can easily cause the frustration of the hair clamping assembly after long-term operation, resulting in the occurrence of a jamming phenomenon. After adopting the above structure, the present invention effectively improves the running stability of the hair clamping assembly by arranging the first ball and the second ball on the inner surface of the movable seat and utilizing a combination of elastic balls and ordinary balls. As an elastic ball, the diameter of the first ball can be elastically reduced when subjected to extrusion force, providing dynamic buffering, thereby reducing the reaction force borne by the clip and the mounting seat on the narrowing side of the bow shaft. This buffering effect not only reduces local friction, but also significantly reduces the frustration of the assembly after long-term operation.

[0009] At the same time, the second ball is located on the widening side of the bow-shaped shaft. Because it is subjected to less force, it can serve as an auxiliary support structure to ensure the overall stability of the hair clamping assembly and reduce the operating burden of the driven gear or the transmission gear. The rolling characteristics of the first ball and the second ball also effectively disperse the friction force, making the contact between the clip and the mounting seat more uniform, thereby improving the durability and service life of the modified hair clamping assembly.

[0010] With this technical solution, the hair gripping component can capture and release hair more smoothly under different working conditions, and can maintain high operating accuracy even when the hair is uneven in thickness or the number of captured and clamped hair changes. In addition, this design can effectively prevent jamming caused by wear, making the device run quieter and more stable, thereby improving the user experience.

[0011] According to one embodiment of the present invention, a plurality of elastic pins are evenly arranged on the inner ring of the mounting seat, the elastic pins are in an eight-shaped shape and the outer ends are connected to the mounting seat as a whole, and the distance between the two inner ends of the elastic pins gradually increases from the outside to the inside along the radial direction of the mounting seat, and the inner ends of the plurality of elastic pins are sleeved on the bow-shaped shaft; the eight-shaped structural design of the elastic pins enables it to have a certain flexibility and floating ability in the radial direction, so that it can adapt to different curvature changes on the human body surface and fit the human body surface more easily. During use, the plurality of mounting seats form a flexible connection with the bow-shaped shaft through the elastic pins, so that the clip can automatically adjust the angle and position during operation to ensure a more precise fit with the skin. At the same time, the design can also effectively disperse the stress generated during operation, reduce the pressure of the clip on the skin, and thus improve the comfort and efficiency of use.

[0012] According to an embodiment of the present invention, the inner ring of the mounting seat is provided with a plurality of reinforcement parts, and the outer end of each of the elastic pins is connected to the corresponding reinforcement part as a whole; the provision of the reinforcement part not only enhances the overall structural strength of the elastic pin and the mounting seat, but also effectively prevents the elastic pin from being deformed or broken due to repeated force during long-term use. By connecting the outer end of the elastic pin with the reinforcement part as a whole, a stable support structure is formed, so that the mounting seat has higher durability while maintaining the radial floating function.

[0013] According to one embodiment of the present invention, a first pin is provided on the side of the driven gear facing the mounting seat, and the first pin is staggered with the elastic pin to form a power transmission structure. During the transmission process, the first pin interacts with the elastic pin to achieve a stable mechanical connection, while ensuring that the power can be smoothly transmitted from the mounting seat to the driven gear. This design utilizes the flexible characteristics of the elastic pin, while ensuring accurate transmission of the transmission force, alleviating the impact force that may be generated by device vibration or instantaneous load changes, thereby improving the stability of operation.

[0014] According to an embodiment of the present invention, a second pin is provided on the side of the transmission gear facing the mounting seat, and the second pin is staggered with the elastic pin; the staggered cooperation of the second pin and the elastic pin ensures that the transmission gear can transmit external power to the mounting seat when working, thereby driving the movement of the clip. In this design, the addition of the second pin provides additional stable support for power transmission, reducing mechanical vibration or imbalance that may be caused by uneven force transmission.

[0015] According to one embodiment of the present invention, a fixed seat is provided on the side of the base away from the movable seat, and a third ball is provided on the inner wall of the fixed seat, whose main function is to provide additional support and stability to ensure smooth relative movement between the base and the movable seat.

[0016] According to an embodiment of the present invention, a driving gear is rotatably mounted on the side away from the movable seat, and the driving gear is located on the inner side of the base and meshes with the transmission gear. Through the meshing of the driving gear and the transmission gear, the external input power can be smoothly transmitted to various parts of the hair clamping assembly. The rotation of the driving gear drives the transmission gear to operate, thereby driving the clamping and releasing actions of the clip.

[0017] According to one embodiment of the present invention, the hair clamping assembly further includes an elastic rod, the two ends of which are respectively in contact with the movable seat and the fixed seat; the clamping force applied by the elastic rod, through the elastic action between the movable seat and the fixed seat, enables the driven gear, the transmission gear and the mounting seat to fit closely together, ensuring that each component maintains good contact and precise transmission during operation. The introduction of such clamping force helps to improve the meshing efficiency between gears, reduce the gap during transmission, and thus improve the operating stability and response speed of the hair clamping assembly.

[0018] According to one embodiment of the present invention, the movable seat is provided with a plurality of mounting parts, and the first ball and the second ball are rollably mounted on the mounting parts; the first ball and the second ball provide smooth rolling support in the movable seat, thereby effectively reducing energy loss caused by friction.

[0019] A hair plucker comprises a body and any one of the above-mentioned hair clamping components, wherein the hair clamping component is detachably mounted on the body. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention. Embodiment 1

[0041] like Figure 5-18 As shown, in this embodiment, a hair clip assembly 10 is disclosed, comprising: Base 11; A movable seat 12, which is rotatably mounted on one side of the base 11; A driven gear 15, a transmission gear 16, a plurality of clips 112 and a plurality of mounting seats 111, wherein the clips 112 and the mounting seats 111 are arranged alternately, and the driven gear 15 and the transmission gear 16 are arranged on both sides of the plurality of mounting seats 111 and are connected in series through a bow shaft 17, and the two ends of the bow shaft 17 are respectively connected to the base 11 and the movable seat 12; Among them, the inner surface of the movable seat 12 is provided with a plurality of first balls 13 and a plurality of second balls 14, the first balls 13 are elastic balls, and the first balls 13 are located on the narrowing side of the bow axis 17, and the second balls 14 are located on the widening side of the bow axis 17. When the outer side of the driven gear 15 or the transmission gear 16 is pushed to abut against the first ball 13, the diameter of the first ball 13 is elastically reduced and remains in a rollable state.

[0042] Further, combined with Figure 5-6 As shown, in this embodiment, one side of the base 11 is rotatably connected to the movable seat 12, and the other side is provided with a fixed seat 11a. The inner side wall of the movable seat 12 is provided with four mounting portions 12a, the two mounting portions 12a arranged side by side at the upper part are used to mount the first ball 13, and the two mounting portions 12a arranged side by side at the lower part are used to mount the second ball 14.

[0043] The second ball 14 is made of a hard stainless steel ball structure, and the first ball 13 is an elastic ball, whose material includes highly elastic polyurethane, silicone or other materials with excellent elasticity and wear resistance, ensuring that it can be elastically deformed and restored to its original shape when subjected to force, thereby providing stable support and buffering functions. The design of the elastic ball enables the first ball 13 to effectively reduce vibration when in contact with the driven gear 15 or the transmission gear 16, thereby improving the smooth operation of the overall hair clamping assembly 10.

[0044] Furthermore, combined with Figure 7-9 As shown, in this embodiment, a rotating shaft 12c is provided at the lower part of the movable seat 12, and the movable seat 12 is rotatably mounted on the base 11 through the rotating shaft 12c. A D-shaped connecting hole 12b is provided in the middle part of the movable seat 12, and one end of the arched shaft 17 has a D-shaped profile adapted to the connecting hole 12b, so that the arched shaft 17 can achieve a stable mechanical connection with the movable seat 12. The cooperation between the D-shaped connecting hole 12b and the arched shaft 17 not only ensures the precise positioning of the arched shaft 17 during the rotation process, but also effectively prevents the transmission instability caused by axial misalignment or misalignment.

[0045] Furthermore, combined with Figure 10-14 As shown, in this embodiment, the hair clip assembly 10 includes twelve mounting seats 111 and twenty-two clips 112. Every two adjacent mounting seats 111 are circumferentially staggered, a clip 112 is fixedly installed on both sides of the middle ten mounting seats 111, and a clip 112 is fixedly installed on the inner side of the two outermost mounting seats 111.

[0046] Furthermore, combined with Figure 14-15 As shown, five extensions 111a are evenly arranged on the outer circumference of each mounting seat 111, and the edge of each extension 111a extends toward both sides, and forms a positioning portion 111b along the axial direction of the mounting seat 111. Bosses 111c are arranged on both sides of the mounting seat 111, and the inner hole 112a of the clip 112 is adapted to the bosses 111c, ensuring that the mounting seat 111 and the clip 112 are stably positioned in the radial direction. Through contour limiting, the clip 112 and the mounting seat 111 also achieve circumferential positioning, preventing the two from deflecting during operation, thereby improving the stability and accuracy of the hair clamping assembly 10.

[0047] Furthermore, combined with Figure 5-6 As shown, in this embodiment, the positioning portions 111b of each two adjacent mounting seats 111 are staggered to ensure that each positioning portion 111b abuts against the clip 112. Specifically, the side of the driven gear 15 facing the mounting seat 111 is provided with a first positioning protrusion 15a and a first pin 15b, and the extension portion 111a on the mounting seat 111 adjacent to the driven gear 15 is staggered with the first positioning protrusion 15a. Similarly, the side of the transmission gear 16 facing the mounting seat 111 is provided with a second positioning protrusion 16a and a second pin 16b, and the extension portion 111a on the mounting seat 111 adjacent to the transmission gear 16 is staggered with the second positioning protrusion 16a. Through this staggered positioning structure, each clip 112 can be accurately fixed.

[0048] Specifically, combined Figure 15-16As shown, a plurality of elastic pins 111d are evenly arranged on the inner circle of the mounting seat 111. The elastic pins 111d are in an eight-shaped shape and the outer ends are connected to the mounting seat 111 as a whole. The distance between the two inner ends of the elastic pins 111d gradually increases from the outside to the inside along the radial direction of the mounting seat 111. The inner ends of the plurality of elastic pins 111d are sleeved on the bow shaft 17.

[0049] Furthermore, in this embodiment, a through hole is provided in the center of the mounting seat 111, and five reinforcement parts 111e are evenly distributed on the inner wall of the through hole. These reinforcement parts 111e are formed by radial protrusions, so that the inner wall of the through hole is more solid and the stability of the structure is enhanced. Each reinforcement part 111e is connected to an elastic pin 111d in an eight-shaped shape, and the narrower ends of the elastic pin 111d are respectively connected to the two sides of the reinforcement part 111e as a whole, and the wider end thereof serves as the inner end of the elastic pin 111d. The inner ends of the five elastic pins 111d are combined to form a cylindrical space, and the bow shaft 17 passes through this space and keeps contact with the inner end of the elastic pin 111d, playing a supporting role, ensuring the stable transmission of force and uniform force. It is worth noting that the elastic pins 111d of the five mounting seats 111 are staggered between adjacent mounting seats 111 and are closely abutted against each other. Through this staggered arrangement, the mounting seat 111 can produce a floating effect in both the arcuate axis 17 direction and the radial direction.

[0050] This floating structure enables the narrow side of the hair clamping assembly 10 to better fit the curve of the human body surface, especially when grasping hair, it can flexibly adapt to different surface shapes, thereby improving the comfort and effect of the hair clamping process. In addition, since the elastic pin 111d can alleviate the pressure and impact generated during the transmission process to a certain extent, it reduces the wear on other mechanical parts, and at the same time improves the durability and service life of the hair clamping assembly 10.

[0051] Specifically, combined Fig.12 As shown, a fixed seat 11a is provided on the side of the base 11 away from the movable seat 12, and a third ball 19 is provided on the inner wall of the fixed seat 11a, which mainly provides additional support and stability to ensure smooth relative movement between the base 11 and the movable seat 12. A driving gear 18 is rotatably mounted on the side away from the movable seat 12, and the driving gear 18 is located on the inner side of the base 11 and meshes with the transmission gear 16.

[0052] Specifically, combined Fig.11 As shown, the hair clamping assembly 10 further includes an elastic rod 110, and two ends of the elastic rod 110 are respectively in contact with the movable seat 12 and the fixed seat 11a.

[0053] Combination Figure 1-4As shown, in other embodiments, a hair plucker is disclosed, including a body 20 and the hair clamping assembly 10 described in this embodiment, and the hair clamping assembly 10 is detachably mounted on the body 20.

[0054] Further, in some other embodiments, the body 20 includes a housing 21, a motor 22 installed inside the housing 21, a reduction gear set 23 and a battery 24. The gear on the output shaft of the motor 22 meshes with the input gear in the reduction gear set 23, thereby transmitting power. A connecting groove 21a is provided at the upper part of the housing 21, and a connecting gear 25 is rotatably installed in the connecting groove 21a, and a sealing sleeve 26 is provided at the bottom of the connecting groove 21a. The shaft of the connecting gear 25 passes through the sealing strip and meshes with the output gear in the reduction gear set 23.

[0055] When the hair clip assembly 10 is connected and plugged into the connection groove 21a, the driving gear 18 and the connecting gear 25 are meshed to ensure the smooth transmission of power. The battery 24 provides power to the motor 22, and the motor 22 drives the connecting gear 25 to rotate through the reduction gear set 23, and then transmits power in sequence through the driving gear 18, the transmission gear 16, the multiple mounting seats 111 and the driven gear 15. In this process, the driven gear 15 rotates relative to the movable seat 12 around the bow shaft 17 to ensure that the clip 112 and the mounting seat 111 move synchronously.

[0056] In addition, the first ball 13 not only plays a lubricating role, but also effectively offsets the axial force of the driven gear 15 along the direction of the bow axis 17, thereby reducing the friction between mechanical parts, reducing vibration, and improving the stability and durability of the overall transmission system.
