Description

Technical Field

[0001] This utility model relates to the field of hair styling technology, and in particular to a multifunctional hair perm. Background Technology

[0002] In the field of hair styling, volumizing tools are commonly used, and their working principle is mainly based on the application of heat effects. Through direct contact between the heated surface and the hair, heat conduction causes plastic deformation of the hair fiber structure, thereby achieving a voluminous and full style. Currently, most mainstream products use a heating plate design with protruding teeth (commonly known as "corner teeth"). This toothed structure allows for targeted heat treatment of the hair strands during the heating process, quickly and efficiently giving the hair a three-dimensional, voluminous look, meeting users' diverse styling needs.

[0003] For example, a hair-volumizing perm disclosed in Chinese Utility Model Patent (Authorization Announcement No.: CN208160307U) includes a control circuit and a clamping plate. The clamping plate consists of an upper clamping plate and a lower clamping plate. An upper heating plate and a lower heating plate are detachably mounted on the inner side of the front end of the upper clamping plate and the inner side of the front end of the lower clamping plate, respectively. Heating components are provided within both the upper and lower heating plates, and these heating components are connected to the control circuit. Protrusions are provided on both the upper and lower heating plates, and the heat generated on the heating plates is conducted to these protrusions. The protrusions are raised pillars, regularly distributed on the upper and lower heating plates, with the pillars on the upper and lower heating plates staggered. This perm uses the staggered protrusions on the heating plates to curl the hair, achieving an effective and quick way to volumize the hair. It is simple to operate and convenient to use.

[0004] However, the hair-volumizing perm disclosed in the aforementioned prior art has the following drawback: both its upper and lower heating plates are equipped with protruding structures. These protruding structures can easily obstruct the smooth entry of hair strands into the perm during use, making it difficult to evenly distribute the hair on the surface of the upper or lower heating plates. This uneven distribution directly causes differences in the heating and shaping effects of the hair, resulting in uneven thickness and poor consistency in the final volumizing style, thus affecting the overall perm quality.

[0005] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0006] The purpose of this invention is to solve the problem that the protruding structure in the prior art easily hinders the smooth entry of hair strands into the hair perm during use, resulting in uneven thickness and poor consistency in the voluminous style. Therefore, a multi-functional hair perm is proposed.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A multifunctional hair curler includes: two clamping arms hinged together and capable of clamping each other, with the clamping end of the two clamping arms defined as the working end; a shaping plate corresponding to each clamping arm, the shaping plate being disposed at the working end of the clamping arm, and the surface of the shaping plate being provided with protruding teeth; a floating plate corresponding to the shaping plate being levitatedly connected to the working end of the clamping arm, the working surface of the floating plate being provided with through holes corresponding to the protruding teeth, when the two clamping arms are clamped, the protruding teeth on the two shaping plates pass through the through holes and engage with each other; the floating plate moves relative to the shaping plate between a first working position and a second working position, when the floating plate is in the first working position, the protruding teeth retract into the through holes, and when the floating plate is in the second working position, the protruding teeth extend out of the through holes; the clamping arms are equipped with elastic elements that abut against the floating plate, the elastic elements causing the floating plate to always have a tendency to move towards the first working position.

[0009] Furthermore, when the floating plate is in the first working position, the working surface of the floating plate is flush with the end face of the protruding tooth.

[0010] Furthermore, a locking element is provided inside the clamping arm, which can lock the floating plate in the first working position.

[0011] Furthermore, the locking member has a locked position and an unlocked position relative to the floating plate; when the locking member is in the locked position, the locking member abuts against the floating plate so that the floating plate is always in the first working position; when the locking member is in the unlocked position, the locking member disengages from the floating plate so that the floating plate can float relative to the shaping plate.

[0012] Furthermore, a locking block is provided on the side of the locking member facing the floating plate, and the floating plate is provided with an unlocking groove that corresponds to and cooperates with the locking block; when the locking member is in the locked position, the locking block and the unlocking groove are misaligned and cooperate; when the locking member is in the unlocked position, the locking block and the unlocking groove are correspondingly cooperated.

[0013] Furthermore, a first protrusion is provided on the side of the locking member facing away from the floating plate, and the clamping arm includes a housing, on which a first groove and a second groove are provided to correspond to and cooperate with the first protrusion, so as to limit the locking member to the locked position or the unlocked position.

[0014] Furthermore, a second protrusion is provided between the first groove and the second groove.

[0015] Furthermore, the locking member has a push button extending from its end, and the housing has a clearance hole for the push button to extend out.

[0016] Furthermore, both ends of the shaping plate are provided with mounting grooves for accommodating elastic elements, and a guide ring is provided in the mounting groove. The floating plate is provided with a guide protrusion corresponding to the guide ring on the side facing the shaping plate. Both ends of the elastic element are respectively sleeved on the outer periphery of the guide ring and the guide protrusion.

[0017] Furthermore, the end of the shaping plate is provided with a guide strip, and the end of the floating plate is provided with a guide groove that slides with the guide strip.

[0018] The beneficial effects of this utility model after adopting the above structure are as follows:

[0019] (1) The multifunctional hair perm described in this utility model includes a floating plate that can be floated relative to the styling plate. When the two clamping arms are opened, the floating plate moves to the first working position under the action of the elastic element, that is, the protruding teeth retract into the through hole. At this time, there are no protruding teeth to block the hair strands from entering the hair perm, so that the hair can be evenly spread on the upper floating plate or the lower floating plate. Afterward, the two clamping arms are clamped together, and the floating plate moves to the second working position under the action of the protruding teeth, overcoming the elastic force of the elastic element. This allows the protruding teeth on the two styling plates to pass through the through hole and interlock with each other, so as to heat the hair evenly and improve the perm effect.

[0020] (2) The multifunctional hair curler of this utility model has a locking member inside the clamping arm. The locking member can lock the floating plate in a first working position. The locking member has a locked position and an unlocked position relative to the floating plate. When the locking member is in the locked position, the locking member abuts against the floating plate so that the floating plate is always in the first working position, that is, the working surface of the floating plate is flush with the end face of the protruding teeth. At this time, the hair curler can achieve a natural and smooth straight hair styling effect. When the locking member is in the unlocked position, the locking member disengages from the floating plate and abuts against it so that the floating plate can float relative to the styling plate. When the two clamping arms are clamped, the protruding teeth on the two styling plates pass through the through hole and interlock with each other to heat the hair evenly and create a fluffy texture with an airy feel. Through the ingenious combination of the floating plate and the locking member, the limitation of the single function of traditional hair curling tools is broken through, the functionality of the hair curler is significantly expanded, and users are brought a more diverse hair styling experience.

[0044] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0045] like Figures 1 to 14As shown, a multi-functional hair curler includes two clamping arms 1, which are hinged and can clamp each other, with the clamping end of the two clamping arms 1 defined as the working end; a shaping plate 2 corresponding to each clamping arm 1, the shaping plate 2 being disposed at the working end of the clamping arm 1, and the surface of the shaping plate 2 being provided with protruding teeth 21; a floating plate 3 corresponding to the shaping plate 2 is floatingly connected to the working end of the clamping arm 1, and the working surface 31 of the floating plate 3 is provided with through holes 311 corresponding to the protruding teeth 21, when the two clamping arms 1 are clamped together... The protruding teeth 21 on the two shaping plates 2 pass through the through holes 311 and mesh with each other; the floating plate 3 moves between a first working position and a second working position relative to the shaping plate 2. When the floating plate 3 is in the first working position, the protruding teeth 21 retract into the through holes 311, and when the floating plate 3 is in the second working position, the protruding teeth 21 extend out of the through holes 311; the clamping arm 1 is equipped with an elastic element 4 that abuts against the floating plate 3, and the elastic element 4 makes the floating plate 3 always tend to move toward the first working position.

[0046] Based on the above embodiments, the present invention aims to provide a multifunctional hair perm, including a floating plate 3 that can be floated relative to the styling plate 2. When the two clamping arms 1 are opened, the floating plate 3 moves to the first working position under the action of the elastic member 4, that is, the protruding teeth 21 retract into the through hole 311. At this time, there are no protruding teeth 21 to block the hair strands from entering the hair perm, so that the hair is evenly spread on the floating plate 3. Afterward, when the two clamping arms 1 are clamped together, the floating plate 3 moves to the second working position under the action of the protruding teeth 21, overcoming the elastic force of the elastic member 4. This allows the protruding teeth 21 on the two styling plates 2 to pass through the through hole 311 and interlock with each other, so as to evenly heat the hair and improve the perming effect.

[0047] For ease of description, the upper clamping arm 1 is defined as the upper clamping arm 12, and the lower clamping arm 1 is defined as the lower clamping arm 13. Correspondingly, the housing 11 corresponding to the upper clamping arm 12 is the upper housing 116, the shaping plate 2 corresponding to the upper clamping arm 12 is the upper shaping plate 26, and the floating plate 3 corresponding to the upper shaping plate 26 is the upper floating plate 36; the housing 11 corresponding to the lower clamping arm 13 is the lower housing 117, the shaping plate 2 corresponding to the lower clamping arm 13 is the lower shaping plate 27, and the floating plate 3 corresponding to the lower shaping plate 27 is the lower floating plate 37. The working surface 31 refers to the opposite surface of the upper shaping plate 26 and the lower shaping plate 27. A heating element 6 is also included, which is correspondingly disposed with the upper shaping plate 26 and / or the lower shaping plate 27, and forms a heat transfer connection. In this embodiment, the upper shaping plate 26 is fixedly connected to the upper shell 116, the upper floating plate 36 is floatingly connected to the upper shaping plate 26, the lower shaping plate 27 is fixedly connected to the lower shell 117, and the lower floating plate 37 is floatingly connected to the lower shaping plate 27. This structural design ensures that the heating element 6 always forms a stable heat transfer cooperation with the upper shaping plate 26 and / or the lower shaping plate 27, resulting in high heat transfer efficiency and a simpler connection structure.

[0048] As another preferred embodiment of this utility model, when the floating plate 3 is in the first working position, the working surface 31 of the floating plate 3 is flush with the end face 211 of the protruding tooth 21. A locking member 5 is provided inside the clamping arm 1, which can lock the floating plate 3 in the first working position. The locking member 5 has a locked position and an unlocked position relative to the floating plate 3; when the locking member 5 is in the locked position, it abuts against the floating plate 3, so that the floating plate 3 is always in the first working position; when the locking member 5 is in the unlocked position, it disengages from the floating plate 3, allowing the floating plate 3 to float relative to the shaping plate 2. In this embodiment, as... Figure 5 , Figure 7 and Figure 8As shown, when the locking member 5 is in the locked position, the locking member 5 abuts against the floating plate 3, so that the floating plate 3 is always in the first working position, that is, the working surface 31 of the floating plate 3 is flush with the end face 211 of the protruding tooth 21. At this time, the hair curler can achieve a natural and smooth straight hair styling effect. When the locking member 5 is in the unlocked position, the locking member 5 disengages from the floating plate 3 and abuts against it, so that the floating plate 3 can float relative to the styling plate 2. When the upper clamping arm 12 and the lower clamping arm 131 are clamped, the protruding tooth 21 of the upper styling plate 26 passes through the through hole 311 on the upper floating plate 36, and the protruding tooth 21 of the lower styling plate 27 passes through the through hole 311 on the lower floating plate 37, and they interlock with each other to heat the hair evenly and create an airy and fluffy texture. By cleverly combining the floating plate 3 and the locking component 5, the limitations of the traditional hair perming tool's single function are broken, significantly expanding the functionality of the hair perming tool and bringing users a more diverse hair styling experience.

[0049] As another preferred embodiment of this utility model, a locking block 51 is provided on the side of the locking member 5 facing the floating plate 3, and the floating plate 3 is provided with an unlocking groove 32 corresponding to the locking block 51; when the locking member 5 is in the locked position, the locking block 51 and the unlocking groove 32 are misaligned; when the locking member 5 is in the unlocked position, the locking block 51 and the unlocking groove 32 are correspondingly engaged. A first protrusion 52 is provided on the side of the locking member 5 facing away from the floating plate 3. The clamping arm 1 includes a housing 11, and the housing 11 is provided with a first groove 111 and a second groove 112 corresponding to the first protrusion 52, for limiting the locking member 5 to the locked position or the unlocked position. A second protrusion 113 is provided between the first groove 111 and the second groove 112. A push button portion 53 extends from the end of the locking member 5, and the housing 11 is provided with an avoidance hole 114 for the push button portion 53 to extend out. In this embodiment, as Figure 6As shown, when the locking member 5 is in the locked position, that is, the first protrusion 52 is engaged in the first groove 111, the locking member 5 abuts against the floating plate 3 so that the floating plate 3 is always in the first working position. At this time, the working surface 31 of the floating plate 3 is flush with the end face 211 of the protrusion 21, and the hair curler can achieve a straight hair styling effect. When the locking member 5 is in the unlocked position, that is, when the first protrusion 52 passes over the second protrusion 113 and is engaged in the second groove 112, the locking member 5 disengages from the floating plate 3 and abuts against it so that the floating plate 3 can float relative to the styling plate 2. So that when the two clamping arms 1 are clamped, the protrusions 21 on the two styling plates 2 pass through the through hole 311 and interlock with each other, so as to heat the hair evenly and create a fluffy texture with an airy feel. By cleverly combining the floating plate 3 and the locking element 5, the limitations of traditional hair-curling tools with their single function are overcome, significantly expanding the functionality of the hair-curling tool and bringing users a more diverse hair-styling experience. In a further preferred embodiment, the through hole 311 corresponds one-to-one with the protruding tooth 21, so that the plane formed by the working surface 31 of the floating plate 3 and the end face 211 of the protruding tooth 21 is flatter and has a smaller gap, which is more conducive to improving the straightening effect.

[0050] In this embodiment, when the first protrusion 52 and the first groove 111 are engaged, the locking block 51 and the unlocking groove 32 are misaligned, so that the floating plate 3 does not have a floating function and the floating plate 3 always remains in the first working position. At this time, the hair curler can achieve a straight hair styling effect. By pushing the locking member 5 through the push button 53, the first protrusion 52 passes over the second protrusion 113 and is inserted into the second groove 112. The locking block 51 and the unlocking groove 32 are engaged, so that the floating plate 3 has a floating function. When the upper shell 116 and the lower shell 117 are clamped, the protruding teeth 21 of the upper shaping plate 26 and the lower shaping plate 27 can extend out from the through hole 311 of the floating plate 3 and interlock with each other to create a fluffy texture with an airy feel. When the first protrusion 52 and the second groove 112 are engaged, and the upper shell 116 and the lower shell 117 are not clamped, the floating plate 3 is always in the first working position under the elastic force of the elastic member 4, which makes it easy for the hair curler to penetrate the hair and make the hair evenly spread on the surface of the upper floating plate 36 or the lower floating plate 37.

[0051] In another preferred embodiment of this utility model, both ends of the shaping plate 2 are provided with mounting grooves 22 for accommodating the elastic element 4. A guide ring 23 is provided within the mounting groove 22. A guide protrusion 33 corresponding to the guide ring 23 is provided on the side of the floating plate 3 facing the shaping plate 2. Both ends of the elastic element 4 are respectively fitted onto the outer periphery of the guide ring 23 and the guide protrusion 33. A guide strip 24 is provided at the end of the shaping plate 2, and a guide groove 34 that slides with the guide strip 24 is provided at the end of the floating plate 3. A guide block 35 is provided at the end of the floating plate 3, and guide grooves 115 corresponding to the guide block 35 are provided at the ends of both the upper housing 116 and the lower housing 117. In this embodiment, as... Figure 5 , Figure 10 and Figure 11 As shown, the mounting groove 22, guide ring 23, and guide protrusion 33 cooperate to reliably install the elastic element 4 and prevent displacement when the elastic element 4 is compressed and reset. Through the cooperation of the guide strip 24 with the guide groove 34 and the guide block 35 with the guide groove 115, the floating plate 3 can move up and down along a predetermined trajectory, improving the stability of the floating plate 3's movement. In a further preferred embodiment, two limiting posts 25 are provided on the side of the shaping plate 2 facing the locking element 5, and the distance between the two limiting posts 25 is adapted to the width of the locking element 5. In this embodiment, as... Figure 9 As shown, the distance between the two limiting posts 25 is adapted to the width of the locking member 5, so that the locking member 5 will not deviate when moving between the locked position and the unlocked position, and the movement is more stable.

[0052] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
