Description

Technical Field

[0001] This utility model relates to the field of cosmetics technology, and in particular to an improved structure of an eyelash curler. Background Technology

[0002] Electric eyelash curlers are convenient to use and offer long-lasting results, making them a popular cosmetic product among beauty enthusiasts. The technical solution disclosed in Chinese Utility Patent Application No. 202020326464.2, entitled "An Electric Eyelash Curler," features a fixed heating element on one side of the front end of the curler's housing. A recessed groove is provided on the other side of the front end of the housing, and a strip-shaped clamp is rotatably fitted into this groove. A return spring is provided between the strip-shaped clamp and the recessed groove. Pressing the tail end of the strip-shaped clamp opens its front end; releasing the pressure closes the front end of the clamp, embedding it into the clamping groove on the heating element. During use, this technical solution suffers from several drawbacks. Because the strip clamp is exposed on the outside of the housing and cannot be protected by it, it is directly impacted by external forces when bumped or knocked, making it prone to falling off the housing or even breaking. This results in poor durability and high user costs. Furthermore, the tail end of the strip clamp can only be pressed within the recessed groove. Due to the limited depth of the recessed groove, the tail end of the strip clamp has limited space for movement, resulting in a small opening angle at the front end. Consequently, it is more difficult to use and cannot clamp the eyelashes securely.

[0003] Given the above-mentioned shortcomings of the existing technology, the applicant believes it is necessary to make technical improvements to provide an electric eyelash curler that is more impact-resistant, durable, and easier to use. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned problems and shortcomings, and to provide a partially improved structure for an electric eyelash curler. By embedding the curling clip strip in a groove and concealing the hinge and pressing parts inside the front half of the shell, the movable curling clip is protected in all directions. In the event of an impact, the movable curling clip is less likely to fall off or break, thus giving the eyelash curler excellent impact resistance and durability. Furthermore, the internal space of the front half of the shell can be used to provide a larger range of motion for the hinge and pressing parts, allowing the front end of the curling clip strip to have a larger opening angle, making it easier to use and more precise in clamping eyelashes. In addition, the hinge and pressing parts can bypass the obstruction of the front half of the shell wall through the transition bend and achieve stable opening or closing of the curling clip strip in a very narrow space.

[0005] The technical solution of this utility model is implemented as follows: A partially improved structure of an electric eyelash curler includes a front half shell and a rear half shell that are interlocked together, a movable curling clamp, a fixed curling clamp, and an electric heating element strip disposed between the movable curling clamp and the fixed curling clamp; characterized in that: the movable curling clamp is composed of an integrally formed pressing part, a hinge part, a curling clamp strip part, and a transition bending part disposed between the hinge part and the curling clamp strip part; the front end of the front half shell is provided with a groove, a through hole communicating with the rear end of the groove, and a button located behind the through hole; the pressing part is in contact with the button from the inside of the front half shell, and a return spring is also provided at the bottom of the pressing part; the hinge part is hinged to a hinge seat provided between the front half shell and the rear half shell, and the transition bending part is inserted into the through hole; the curling clamp strip part is embedded in the groove and, under the action of the return spring, the front part of the curling clamp strip part is interlocked with the fixed curling clamp disposed on the front end of the rear half shell.

[0006] Furthermore, the front half housing is composed of a front sub-shell and a front main shell that are interlocked together. The groove is provided on the surface of the front sub-shell, the through hole is provided at the interlocking point of the front sub-shell and the front main shell, and the button is provided on the front main shell.

[0007] Furthermore, the vertical length of the front sub-shell is less than the vertical length of the front main shell.

[0008] Furthermore, the lower end of the front sub-shell is provided with a sleeve portion and a pin hole, and the upper end of the front main shell is provided with a sleeve inner cavity and a pin. The front sub-shell is assembled together with the front main shell by sleeve-fitting the sleeve portion and sleeve inner cavity and fastening the pin hole and pin.

[0009] Furthermore, the front main housing is also provided with a button hole, the button is fitted into the button hole, and a limiting bottom edge is provided at the bottom of the button to form an anti-detachment assembly with the button hole.

[0010] Furthermore, the hinge seat is located in the inner cavity of the rear half shell. The hinge seat is formed by two vertical plates. A half-shaft hole is provided at the top of the vertical plate. The two ends of the hinge part are also provided with hinge shafts that are hinged to the half-shaft holes.

[0011] Furthermore, it also includes a cap shell, a handle shell, and an annular decorative piece. The front half shell and the rear half shell are provided with a protruding ring in the middle. The handle shell is fitted onto the lower half of the front half shell and the rear half shell. The cap shell is fitted onto the upper half of the front half shell and the rear half shell. The annular decorative piece is fitted onto the protruding ring.

[0012] Furthermore, the cap shell and handle shell are provided with anti-misfit notches at their ports; the handle shell port is also provided with anti-misfit recesses, and the rear half shell surface is provided with corresponding protrusions that fit into the recesses.

[0013] Furthermore, it also includes decorative elements, which consist of end caps and side wings on both sides of the end caps; the top of the cap shell is also provided with a recessed groove for the decorative elements to be installed.

[0014] Furthermore, it also includes a decorative cap, with a corresponding cavity at the bottom of the handle housing that engages with the decorative cap.

[0015] The beneficial effects of this utility model are: Firstly, by placing the hinge and pressing parts inside the front half of the housing and concealing the curling clip strip within a groove, the movable curling clip is fully enclosed for protection. Even if the eyelash curler falls to the ground during use, the movable curling clip will not fall off and is less likely to break, thus greatly improving the durability and reliability of the electric eyelash curler and reducing the cost of use for consumers.

[0016] Secondly, by placing the pressing part and the hinge part inside the front half of the shell, the internal space of the front half of the shell can be utilized to provide a larger range of motion for the pressing part and the hinge part. This allows the front end of the curling clip strip to open to a larger angle, making it easier to use and more precise to clamp the eyelashes for heating and curling.

[0017] In addition, the transition bend allows the hinge to bypass the obstruction of the front shell wall and be placed inside the front shell. This also allows the hinge and pressing parts to have sufficient room to move even in the very small space inside the front shell, thus helping to reduce the volume of the front shell and making the electric eyelash curler more compact and smaller in size.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0029] like Figure 2 , 3 As shown in Figures 4 and 5, this utility model provides a partially improved structure for an electric eyelash curler, including a front half-shell 1 and a rear half-shell 2 that are interlocked together, a movable curling clamp 3, a fixed curling clamp 4, and an electric heating element 5 disposed between the movable curling clamp 3 and the fixed curling clamp 4. To achieve the purpose proposed by this utility model, the movable curling clamp 3 is composed of an integrally formed pressing part 31, a hinge part 32, a curling clamp strip part 33, and a transition bending part 34 disposed between the hinge part 32 and the curling clamp strip part 33. The front end of the front half-shell 1 is provided with grooves 1 in sequence. 1. A through hole 12 that communicates with the rear end of the groove 11, and a button 13 located behind the through hole 12; the pressing part 31 is in contact with the button 13 from the inside of the front half housing 1, and a return spring 6 is also provided at the bottom of the pressing part 31; the hinge part 32 is hinged to the hinge seat 7 provided between the front half housing 1 and the rear half housing 2, and the transition bending part 34 is inserted into the through hole 12; the coil clip strip part 33 is embedded in the groove 11 and, under the action of the return spring 6, the front part of the coil clip strip part 33 is engaged with the fixed coil clip 4 provided on the front end of the rear half housing 2.

[0030] In this way, the transition bend 34 allows the hinge 32 and the pressing part 31 to avoid the side wall of the front half-shell 1 and be placed inside the front half-shell 1, providing a large range of motion within the narrow interior of the front half-shell 1. This allows the front part of the curling clip 33 to open at a larger angle, making it not only easier to use but also allowing for precise clamping of the eyelashes, heating and curling them for a very good curling effect. This application, through partial improvements to the movable curling clip 3 and the front half-shell 1 in the electric eyelash curler, makes the electric eyelash curler more robust and durable, easier to use, and more compact, thereby greatly improving the quality of the electric eyelash curler and making it more attractive to consumers.

[0031] like Figure 3 , 7 As shown, to enable the front half-shell 1 and the rear half-shell 2 to be quickly fastened together, the front half-shell 1 has multiple male fasteners 16 at its edge, and the rear half-shell 2 has corresponding female fasteners 26 at its edge. Furthermore, the front half-shell 1 has multiple positioning recesses 17 with concave holes, and the rear half-shell 2 has multiple positioning protrusions 27 that are inserted into the positioning recesses 17. These positioning protrusions 27 and positioning recesses 17 not only facilitate rapid positioning between the front half-shell 1 and the rear half-shell 2, but also further enhance the compressive strength of the assembled front half-shell 1 and rear half-shell 2, providing stronger protection for the internal components.

[0032] Furthermore, such as Figure 3 , 4 As shown, the back of the pressing part 31 is provided with a spring chamber 61, and the rear half shell 2 is provided with a spring protrusion 62; the spring 6 is fitted on the spring protrusion 62 and embedded in the spring chamber 61, so that even if the pressing part 31 swings back and forth, the spring 6 will not fall off.

[0033] like Figure 3As shown, the fixing clamp 4 is integrally mounted on the front end of the rear half-shell 2, and the fixing clamp 4 is provided with a strip groove 41 for embedding the electric heating element 5. The electric heating element 5 is preferably made of copper sheet with excellent thermal conductivity, electrical conductivity, and toughness. In order to make the electric heating element 5 firmly embedded in the strip groove 41, elastic folded edges 51 are provided on both sides of the electric heating element 5. In this way, the elastic folded edges 51 on both sides abut against the groove wall of the strip groove 41, so that the electric heating element 5 is embedded in the strip groove 41 and is not easy to fall out. Furthermore, a mounting hole 42 communicating with the strip groove 41 is provided at the top of the fixed roll clamp 4, and a stop block 43 is provided at the top of the fixed roll clamp 4 inside the mounting hole 42. A protrusion 52 is provided at the top of the electric heating element strip 5. The protrusion 52 passes through the mounting hole 42 and elastically abuts against the stop block 43, thereby further enhancing the stability of the electric heating element strip 5 assembled on the fixed roll clamp 4.

[0034] like Figure 3 , 6 As shown in Figure 7, to facilitate the assembly of the movable curling clip 3 onto the front half-shell 1, the front half-shell 1 is composed of a front auxiliary shell 14 and a front main shell 15 that are interlocked together. A groove 11 is provided on the surface of the front auxiliary shell 14, a through hole 12 is provided at the interlocking point between the front auxiliary shell 14 and the front main shell 15, and a button 13 is provided on the front main shell 15. Thus, during assembly, the pressing part 31 and the hinge part 32 of the movable curling clip 3 can be first inserted into the front main shell 15, and then the front auxiliary shell 14 can be fastened onto the front main shell 15. This allows the through hole 12 to be relatively small, providing better restraint for the curling clip strip 33 and preventing it from wobbling during use, making the electric eyelash curler more stable.

[0035] Furthermore, such as Figure 6 , 7 As shown, the groove 11 extends through the length of the front sub-shell 14, so that after the front sub-shell 14 is fastened onto the front main shell 15, a through hole 12 is formed between the rear end of the groove 11 and the front main shell 15. Furthermore, in order to enable the movable coil clamp 3 to have a large swing angle, an arc-shaped clearance recess 120 is also provided at the top of the front main shell 15.

[0036] like Figure 6 , 7As shown, the front sub-shell 14 provides support and protection for the coiled strip 33. However, the split design weakens the shell's strength. To ensure the front half-shell 1 has excellent overall mechanical strength, the vertical length of the front sub-shell 14 is less than the vertical length of the front main shell 15. This minimizes the adverse effects of the front sub-shell 14 on the mechanical strength of the front half-shell 1, ensuring excellent overall mechanical strength and providing good protection for the internal components.

[0037] like Figure 7 As shown, in order to quickly and securely assemble the front sub-shell 14 and the front main shell 15 together, the lower end of the front sub-shell 14 is provided with a sleeve portion 141 and a pin hole 142, and the upper end of the front main shell 15 is provided with a sleeve inner cavity 151 and a pin 152 respectively. In this way, the front sub-shell 14 is assembled with the front main shell 15 through the sleeve portion 141 sleeved with the sleeve inner cavity 151 and the pin hole 142 and the pin 152 fastened together. Furthermore, the pin hole 142 is provided on the sleeve portion 141, and the pin 152 is provided in the sleeve inner cavity 151. When the sleeve portion 141 is sleeved on the sleeve inner cavity 151, the pin hole 142 and the pin 152 are fastened together at the same time, making the structure of the front half shell 1 very compact.

[0038] like Figure 3 , 6 As shown in Figure 7, the front main housing 15 is also provided with a button hole 153. The button 13 is fitted into the button hole 153, and a limiting bottom edge 131 is provided at the bottom of the button 13 to form an anti-detachment assembly with the button hole 153. During assembly, the button 13 passes through the inside of the front main housing 15 into the button hole 153, and the limiting bottom edge 131 is fitted into the inner opening of the button hole 153. In this way, during use, the button 13 moves back and forth in the button hole 153. Due to the limitation of the button hole 153 wall, the button 13 will not wobble, and the operation feel is good. After resetting, the limiting bottom edge 131 is fitted into the inner opening of the button hole 153, and the button 13 will not fall out of the button hole 153.

[0039] like Figure 3 As shown, the hinge seat 7 is disposed in the inner cavity of the rear half-shell 2. The hinge seat 7 is formed by two upright plates 71. A half-shaft hole 72 is provided at the top of the upright plate 71. The two ends of the hinge part 32 are also provided with hinge shafts 321 that are hinged to the half-shaft holes 72. In this way, the pressing part 31 swings back and forth with the hinge shaft 321 as the fulcrum, thereby driving the curling clip strip part 33 to swing back and forth to realize the opening or closing state between the curling clip strip part 33 and the fixed curling clip 4, thereby completing the clamping and curling of eyelashes.

[0040] Furthermore, such as Figure 7As shown, two support protrusions 73 are provided inside the front main housing 15 for supporting the hinge shaft 321. The hinge part 32 is sandwiched between the two support protrusions 73. One side of the hinge shaft 321 is supported on the support protrusion 73. The upright plate 71 abuts against the support protrusion 73. The other side of the hinge shaft 321 is wrapped in the half shaft hole 72. In this way, when the hinge part 32 swings, both the front and rear sides can be strongly supported and will not deviate, so that the eyelashes can be clamped very stably and powerfully.

[0041] like Figure 1 , 2 As shown, the electric eyelash curler body in this invention comprises the front half-shell 1 and rear half-shell 2, the movable curling clip 3, the fixed curling clip 4, the electric heating element 5, and the battery circuit board. To protect the electric eyelash curler body and improve product quality, this invention also includes a cap shell 8, a handle shell 9, and an annular decorative piece 10. A protruding ring 20 is provided in the middle of the front half-shell 1 and rear half-shell 2. The handle shell 9 is fitted onto the lower half of the front half-shell 1 and rear half-shell 2, the cap shell 8 is fitted onto the upper half of the front half-shell 1 and rear half-shell 2, and the annular decorative piece 10 is fitted onto the protruding ring 20. Thus, after the front half-shell 1 and rear half-shell 2 are fastened together, the outer sides are further protected by the cap shell 8, handle shell 9, and annular decorative piece 10, providing all-around protection and improving the impact resistance and durability of the electric eyelash curler.

[0042] like Figure 2 , 8 As shown in Figure 10, to improve assembly efficiency and prevent assembly errors, the cap shell 8 and handle shell 9 are provided with anti-misassembly notches 30 at their ports; the handle shell 9 is also provided with an anti-misassembly recess 40 on its inner side at its port, and the rear half shell 2 is provided with a corresponding protrusion 50 that fits into the recess 40. In this way, during assembly, not only can the cap shell 8 and handle shell 9 be quickly and correctly assembled with the front half shell 1 and rear half shell 2, but the cooperation between the recess 40 and the protrusion 50 also prevents the handle shell 9 from rotating after assembly, thus ensuring the stability of the assembled structure.

[0043] like Figure 2 , 9 As shown, to further improve product quality, this utility model also includes a decorative component 60, which is composed of an end cap 601 and side wings 602 disposed on both sides of the end cap 601; the top of the cap shell 8 is also provided with a recessed groove 81 for the decorative component 60 to be inserted. In this way, the decorative component 60 is placed in the recessed groove 81, making the surface of the cap shell 8 very flat.

[0044] Furthermore, such as Figure 2As shown, the recessed groove 81 is composed of a horizontal groove 811 located on the top surface of the cap shell 8 and vertical grooves 812 located on the left and right sides of the top of the cap shell 8. In this way, the end cap 601 is hidden in the horizontal groove 811 and the side wing 602 is hidden in the vertical groove 812, thereby increasing the contact area between the decorative part 60 and the recessed groove 81, making the connection between the two more secure.

[0045] Furthermore, such as Figure 2 , 9 As shown, in order to enable the decorative part 60 to be quickly and securely assembled onto the cap shell 8, the bottom surface of the end cover 601 is provided with an insert protrusion 603, the bottom end of the side wing 602 is provided with an insert protrusion 604, the bottom of the horizontal groove 811 is provided with an insert hole 813 for inserting the insert protrusion 603, and the bottom end of the vertical groove 812 is provided with an insert slot 814; in this way, the insert protrusion 603 is inserted into the insert hole 813 and the insert protrusion 604 is inserted into the insert slot 814, so that the decorative part 60 can not only be hidden in the hiding groove 81, but also be securely assembled onto the cap shell 8.

[0046] like Figure 2 , 10 As shown, to further improve product quality, this utility model also includes a decorative cap 70, and the bottom end of the handle shell 9 is correspondingly provided with a cavity 91 that is snapped into the decorative cap 70. In this way, the decorative cap 70 can be quickly assembled to the bottom end of the handle shell 9 by snapping it into the cavity 91.

[0047] Furthermore, such as Figure 2 The decorative cap 70 shown has a snap-fit ​​protrusion 701 at its top. By snapping the protrusion 701 into the cavity 91, the decorative cap 70 can be quickly assembled onto the bottom of the handle shell 9, and the outer surfaces of the two are flush and joined together, thus improving product quality.
