Description

Technical Field

[0001] The present invention relates to the technical field of beauty instruments, and particularly to a hairpin moving mechanism for a hair curler. Background Art

[0002] A hair curler is one of the commonly used devices in beauty salons. Due to its portability and ease of use, it is quite popular. Its main components are a handle and a heating drum. The hair curler is designed to control the temperature with a circuit panel, improve the protein structure of the hair to create curls, and protect the hair quality during the curling process. Most of the existing hair curlers have an exposed heating drum design. During use, users need to temporarily fix the hair wound around the heating drum with their fingers, which is very inconvenient. Based on this, hair curlers with hairpins have emerged on the market.

[0003] The microwave hair curler with the patent number CN2349869Y and the hair curler with the patent number CN107157085A both have hairpins for temporarily fixing hair. However, the designs of such hairpins all adopt a single-sided opening and closing structure, that is, one end of the hairpin is used as the pivot point for rotation, and the other end is opened. This structure is likely to result in a greater clamping force on the hair near the pivot point and a smaller clamping force on the hair far from the pivot point when fixing the hair, making it difficult to comprehensively clamp the hair wound around the heating drum. Moreover, when clamping, the hairpin will generate a pushing force along the axial direction of the heating drum, causing the hair far from the pivot point to be easily pushed out of the clamping drum during curling by the user, resulting in the hair far from the pivot point being prone to loosening, which is not conducive to the user's smooth curling.

[0004] Therefore, it is necessary to propose a hairpin moving mechanism for a hair curler to solve the problem that the hairpin is difficult to comprehensively clamp the wound hair. Summary of the Invention

[0005] In order to solve the above problems, the present invention proposes a hairpin moving mechanism for a hair curler to solve the problem that the hairpin is difficult to comprehensively clamp the wound hair.

[0006] The present invention is achieved through the following technical solutions:

[0007] The present invention provides a hairpin moving mechanism for a hair curler, which includes a heating core assembly, a motor, and a clamping member. A heating rod and a connecting portion are provided on the heating core assembly. The connecting portion is located on one side of the heating rod. The motor is fixedly connected within the connecting portion. One end of the clamping member forms a sliding connection with one end of the connecting portion in a direction perpendicular to the axial direction of the heating rod. The clamping member is arranged parallel to the heating rod. The rotating shaft of the motor penetrates through the connecting portion and extends into the clamping member and forms a transmission connection with the interior of the clamping member. A clamping arc surface is provided on one side of the clamping member. The cylindrical space formed by the extension of the clamping arc surface from both sides wraps the heating rod. The rotation of the motor drives the clamping member to slide relative to the connecting portion, so that the clamping member approaches or moves away from the heating rod.

[0008] Further, the rotating shaft of the motor is arranged parallel to the heating rod.

[0009] Further, two support plates and a placement groove are symmetrically provided at one end of the connecting portion. The placement groove is located between the two support plates and faces the heating rod. Both support plates are arranged parallel to the heating rod. A sliding seat is provided at one end of the clamping member. A part of the sliding seat is received within the placement groove and is respectively in sliding connection with the support plates on both sides. The rotating shaft of the motor extends into the sliding seat and forms a transmission connection with the interior of the sliding seat.

[0010] Further, sliding grooves are provided on the support plates. The sliding grooves communicate with the placement groove. Sliding blocks are symmetrically provided on both sides of the sliding seat. The two sliding blocks respectively correspond to the two sliding grooves one by one. The sliding blocks are received within the sliding grooves.

[0011] Further, a limiting boss for limiting the sliding seat to slide to the position closest to the heating rod is provided on the support plate. The limiting boss is located on one side of the sliding groove and close to the heating rod.

[0012] Further, a balance plate is provided on the sliding seat. The balance plate is located above the support plate and fits with the upper surface of the support plate.

[0013] Further, a transmission portion is provided at the bottom of the sliding seat. The rotating shaft of the motor penetrates through the connecting portion and extends into the transmission portion and forms a transmission connection with the transmission portion.

[0014] Further, a transmission groove is provided on the transmission portion. The rotating shaft of the motor is received within the transmission groove. One side of the rotating shaft of the motor forms a transmission connection with the groove wall on one side of the transmission groove, and the other side of the rotating shaft of the motor contacts the groove wall on the other side of the transmission groove.

[0015] Further, a rack is provided on the groove wall on one side of the transmission groove, a transmission gear is provided on the rotating shaft of the motor, and the transmission gear is meshed with the rack.

[0016] Further, a fixing groove is provided on the connecting portion, the fixing groove is located below the placing groove, and a part of the motor is received in the fixing groove.

[0017] Advantages of the present invention:

[0018] The present invention uses the method of driving the clamping member to slide by a motor to clamp the hair wound around the heating rod in parallel, so that the clamping member can comprehensively clamp the wound hair, ensuring that the hair is subjected to a balanced clamping force; after the hair is wound around the heating rod, when the motor rotates forward, it drives the clamping member to slide towards the heating rod, and the clamping member always remains parallel to the heating rod during the sliding process. When clamping the hair, the force applied by the clamping member to the hair wound around the heating rod is always a force perpendicular to the axial direction of the heating rod. That is, when the user uses the hair curler to curl the hair, the wound hair will not be subjected to a driving force along the axial direction of the heating rod due to the clamping force of the clamping member, ensuring that the hair can be firmly wound around the heating rod for curling. When it is necessary to release the clamping member, the motor rotates in the reverse direction, and at this time, the clamping member slides in the direction away from the heating rod and also always remains parallel to the heating rod during the sliding process;

[0019] The sliding mode of the clamping member of the present invention adopts a direct transmission connection with the rotating shaft of the motor, eliminating the complicated transmission mechanism and facilitating the rapid assembly of workers; the motor drives the rack provided on the groove wall of the transmission groove to move through the gear column on the rotating shaft, thereby driving the sliding of the clamping member. During assembly, only need to slide the clamping member into the placing groove and then insert the rotating shaft of the motor into the sliding seat, so that the gear column on the rotating shaft of the motor is meshed with the rack on the groove wall of the transmission groove, which is convenient for workers to quickly assemble;

[0020] In summary, the hairpin moving mechanism for the hair curler of the present invention can comprehensively and firmly clamp the hair, ensuring that the hair can be firmly wound around the heating rod; at the same time, the sliding mode of the clamping member adopts a direct transmission connection with the rotating shaft of the motor, eliminating the complicated transmission mechanism and facilitating the rapid assembly of workers.

[0031] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0032] Please refer to Figures 1-6 , the present invention provides a hairpin moving mechanism for a hair curler, including a heating core assembly 1, a motor 2, and a clamping member 3. The heating core assembly 1 is provided with a heating rod 11 and a connecting portion 12. The connecting portion 12 is located on one side of the heating rod 11. The motor 2 is fixedly connected within the connecting portion 12. One end of the clamping member 3 forms a sliding connection with one end of the connecting portion 12 in a direction perpendicular to the axial direction of the heating rod 11. The clamping member 3 is arranged parallel to the heating rod 11. The rotating shaft of the motor 2 penetrates through the connecting portion 12 and extends into the clamping member 3 and forms a transmission connection with the interior of the clamping member 3. One side of the clamping member 3 is provided with a clamping arc surface 31. The cylindrical space formed by the clamping arc surface 31 extending from both sides wraps the heating rod 11. The rotation of the motor 2 drives the clamping member 3 to slide relative to the connecting portion 12, so that the clamping member 3 approaches or moves away from the heating rod 11.

[0033] In this embodiment:

[0034] The heating core assembly 1 is used for heating to curl hair;

[0035] The heating rod 11 is used for heating;

[0036] The connecting portion 12 is used to provide a stable installation structure for the motor 2 and the clamping member 3;

[0037] The motor 2 is used to drive the clamping member 3 to slide.

[0038] The rotating shaft is used to transmit the rotational force of the motor 2 to the clamping member 3.

[0039] The clamping member 3 is used to clamp the hair wound around the heating rod 11.

[0040] The clamping arc surface 31 is used to fit the hair wound around the heating rod 11.

[0041] Specifically, the hairpin moving mechanism for the hair curler is installed in the curling groove at one end of the hair curler. The heating rod 11 and the motor 2 are both electrically connected to the circuit board inside the hair curler. The user can control the forward or reverse rotation of the motor 2 by pressing the button on the surface of the hair curler, so as to control the clamping member 3 to slide towards or away from the heating rod 11.

[0042] After the hair is wound around the heating rod 11, when the motor 2 rotates forward, it drives the clamping member 3 to slide towards the heating rod 11. During the sliding process of the clamping member 3, it always remains parallel to the heating rod 11. When clamping the hair, the force applied by the clamping member 3 to the hair wound around the heating rod 11 is always a force perpendicular to the axial direction of the heating rod 11. That is, when the user uses the hair curler to curl the hair, the wound hair will not be subjected to a driving force along the axial direction of the heating rod due to the clamping force of the clamping member 3, ensuring that the hair can be firmly wound around the heating rod 11 for curling. When it is necessary to release the clamping member 3, the motor 2 rotates in the reverse direction. At this time, the clamping member 3 slides towards the direction away from the heating rod 11 and also remains parallel to the heating rod 11 during the sliding process.

[0043] Furthermore, the rotating shaft of the motor 2 is arranged in parallel with the heating rod 11.

[0044] In this embodiment:

[0045] The parallel arrangement of the rotating shaft of the motor 2 and the heating rod 11 can save the external occupied space during the layout of the motor 2, and at the same time eliminate the setting of redundant transmission mechanisms, which is convenient for the layout of the heating core assembly 1 in the hair curler housing.

[0046] Further, two support plates 121 and a placement groove 122 are symmetrically provided at one end of the connecting portion 12. The placement groove 122 is located between the two support plates 121 and faces the heating rod 11. The two support plates 121 are both arranged parallel to the heating rod 11. One end of the clamping member 3 is provided with a sliding seat 32. A part of the sliding seat 32 is received in the placement groove 122, and both sides are respectively slidably connected to the support plates 121. The rotating shaft of the motor 2 extends into the sliding seat 32 and forms a transmission connection with the inside of the sliding seat 32; a sliding groove 1211 is provided on the support plate 121. The sliding groove 1211 communicates with the placement groove 122. Two sliding blocks 321 are symmetrically provided on both sides of the sliding seat 32. The two sliding blocks 321 respectively correspond to the two sliding grooves 1211 one by one, and the sliding blocks 321 are received in the sliding grooves 1211.

[0047] In this embodiment:

[0048] The support plates 121 are used to provide a sliding support structure for the sliding seat 32, so that the sliding seat 32 can be stable during the sliding process;

[0049] The sliding groove 1211 is used to provide a placement space for the sliding block 321;

[0050] The placement groove 122 is used to provide a sliding space for the sliding seat 32;

[0051] The sliding seat 32 is used to provide a structure for the clamping member 3 to be slidably connected to the two support plates 121;

[0052] The sliding blocks 321 are used to provide a sliding support structure for the sliding seat 32, so that the sliding seat 32 can slide smoothly;

[0053] Specifically, with the assistance of the two support plates 121, when the rotating shaft of the motor 2 rotates, the sliding seat 32 can slide smoothly in the placement groove 122.

[0054] Further, the support plate 121 is provided with a limit boss 1212 for limiting the sliding seat 32 to slide to the position closest to the heating rod 11. The limit boss 1212 is located on one side of the sliding groove 1211 and close to the heating rod 11.

[0055] In this embodiment:

[0056] The limit boss 1212 is used to limit the sliding position of the sliding seat 32, prevent the sliding seat 32 from being too close to the heating rod 11, so that the clamping member 3 can maintain a certain clamping distance, and further prevent the clamping member 3 from clamping the hair excessively and causing damage to the hair.

[0057] Further, a balance plate 322 is provided on the sliding seat 32. The balance plate 322 is located above the support plate 121 and fits the upper surface of the support plate 121.

[0058] In this embodiment:

[0059] The balance plate 322 is used to provide a structure for the sliding seat 32 to maintain balance when sliding. Since the sliding seat 32 slides under the drive of the rotating shaft of the motor 2, a deflection force in the sliding direction is generated when the rotating shaft of the motor 2 rotates to drive the sliding seat 32 to slide. This deflection force causes the sliding seat 32 to be pressed toward a support plate 121, causing the outer side of the sliding block 321 to be pressed against the groove wall of the sliding groove 1211. After long-term use, the outer side of the sliding block 321 and the groove wall of the sliding groove 1211 will be worn. This is caused by the sliding connection. The gap will increase after wear. After the gap increases, when the sliding seat 32 slides again, it will be slightly deflected by the deflection force. That is, at this time, not only the entire outer side of the sliding block 321 is in contact with the entire groove wall of the sliding groove 1211, but a part of an inclined surface of the sliding block 321 is in contact with the groove wall of the sliding groove 1211. Such contact will increase the friction force, causing the sliding seat 32 to be blocked when sliding, and this friction force is not enough to block the rotational force of the rotating shaft of the motor 2, so the sliding seat 32 will continue to slide, but The deflection force still exists. During the sliding of the sliding seat 32, a portion of an inclined surface of the sliding block 321 will be pushed by the driving force of the rotating shaft of the motor 2. Since the friction between a portion of an inclined surface of the sliding block 321 and the groove wall of the sliding groove 1211 is not enough to prevent the sliding of the sliding seat 32, the sliding seat 32 is prone to vibration when sliding unsmoothly, causing the entire clamping member 3 to vibrate. In order to prevent the sliding seat 32 from vibrating when sliding due to the small gap between the sliding block 321 and the groove wall of the sliding groove 1211, it is necessary to A balancing plate 322 is added to the top of the sliding seat 32, and the balancing plate 322 fits against the support plate 121 from above when the sliding seat 32 slides. Since the balancing plate 322 is not affected by the deflection force generated when the motor 2 rotates, there is not too much squeezing force on the upper surface of the support plate 121, which reduces the wear of the balancing plate 322 and does not generate a large gap when the sliding seat 32 slides, thereby ensuring the tightness between the sliding seat 32 and the support plate 121, allowing the sliding seat 32 to slide more stably and preventing the clamping member 3 from vibrating.

[0060] Further, a transmission part 323 is provided at the bottom of the sliding seat 32. The rotating shaft of the motor 2 penetrates through the connecting part 12 and extends into the transmission part 323 and forms a transmission connection with the transmission part 323; a transmission groove 3231 is provided on the transmission part 323. The rotating shaft of the motor 2 is received in the transmission groove 3231. One side of the rotating shaft of the motor 2 forms a transmission connection with the groove wall on one side of the transmission groove 3231, and the other side of the rotating shaft of the motor 2 contacts the groove wall on the other side of the transmission groove 3231; a rack 32311 is provided on the groove wall on one side of the transmission groove 3231, and a transmission tooth is provided on the rotating shaft of the motor 2. The transmission tooth forms a meshing connection with the rack 32311.

[0061] In this embodiment:

[0062] The transmission part 323 is used to provide a structure for the sliding seat 32 to form a transmission connection with the rotating shaft of the motor 2;

[0063] The transmission groove 3231 is used to form a transmission connection with the rotating shaft of the motor 2. This transmission connection can be a tight connection, that is, transmission is carried out by relying on the frictional force between the outer wall of the rotating shaft of the motor 2 and the groove wall of the transmission groove 3231, or it can be carried out by relying on the meshing transmission between the transmission tooth and the rack 32311;

[0064] The rack 32311 is used to provide a structure for the transmission groove 3231 to form a meshing connection with the transmission tooth on the rotating shaft of the motor 2;

[0065] The transmission tooth is used to provide a structure for the rotating shaft of the motor 2 to mesh with the rack 32311;

[0066] Specifically, the motor 2 drives the rack 32311 provided on the groove wall of the transmission groove 3231 to move through the gear column on the rotating shaft, thereby driving the sliding of the clamping member 3. During assembly, only need to slide the clamping member 3 into the placement groove 122 and then insert the rotating shaft of the motor 2 into the sliding seat 32, so that the gear column on the rotating shaft of the motor 2 meshes with the rack 32311 on the groove wall of the transmission groove 3231. There is no need to install too many transmission mechanism connecting parts, which is convenient for workers to quickly assemble.

[0067] Further, a fixing groove 123 is provided on the connecting part 12. The fixing groove 123 is located below the placement groove 122, and a part of the motor 2 is received in the fixing groove 123.

[0068] In this embodiment:

[0069] The fixing groove 123 is used to provide a stable placement space for the motor 2.

[0070] In summary, the hairpin moving mechanism used for the curling iron can fully and firmly clamp the hair, ensuring that the hair can be firmly wrapped around the heating rod; at the same time, the sliding mode of the clamping part adopts a mode of directly realizing transmission connection with the rotating shaft of the motor, eliminating complicated transmission mechanisms and facilitating workers to quickly assemble.

[0071] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
