Description

Technical field

[0001] The utility model relates to the technical field of hairdressing equipment, in particular to a hairdressing device. [Background Technology]

[0002] In daily life, people are paying more and more attention to hair care, but going to a barber shop is time-consuming and increases expenses, so many people use hair styling tools on their own. Whether it is to reduce the frizz caused by natural curls or to change the straight or curly hair style according to mood, these products can easily shape the hair. Therefore, hair styling tools have become a popular hair styling device.

[0003] See also Figure 1 When using existing hair styling devices, users often press the clamping portion H of the device against their scalp, forehead, cheeks, or other areas to fluff the roots of their hair or manage their bangs. Some users also hold the clamping portion H to facilitate pushing and clamping their hair, in order to achieve better straightening or curling effects. However, because existing hair styling devices often have a heating component embedded within the housing of the clamping portion H, the heat transferred from the heating component to the housing of the clamping portion H causes the housing to become hot. When users press the clamping portion H against their scalp, forehead, cheeks, or other areas, or hold the clamping portion H, they may experience discomfort or even burns due to the overheating housing.

[0004] In order to solve the technical problem that hairdressing tools are easy to get hot and have poor heat insulation, some hairdressing tools have complex anti-scalding structures installed on the shell to prevent burns. In addition to increasing the size and weight of the hairdressing tools, it also leads to increased costs. [Utility Model Content]

[0032] Compared with the prior art, the hairdressing device provided by the present invention has the following advantages:

[0033] 1. A hairdresser provided in an embodiment of the present invention includes two clamping plates and a handle connecting the two clamping plates. The clamping plates include a housing, a heating plate, and a connecting structure connecting the housing and the heating plates. The two heating plates face opposite each other, defining a working surface. The connecting structure is disposed on a side of the heating plate facing away from the working surface. An insulating gap is formed between the housing and the heating plates, and the heating plates can be reduced relative to the insulating gap. The hairdresser of the present invention utilizes air as the insulating material to significantly reduce the amount of heat transferred from the heating plates to the housing, thereby preventing burns when the user touches the housing. Furthermore, the insulating gap is formed by the housing and the heating plates being suspended by the connecting structure. Simply adjusting the height of the connecting structure allows the desired insulating gap size to be achieved, thereby achieving the desired insulation effect. This facilitates mass production and reduces costs. Furthermore, the connecting structure allows the heating plates to move relative to the housing. When the heating plates move relative to the housing, the height of the insulating gap can be reduced, allowing the heating plates to better adapt to contact and fit the hair, enhancing the user experience.

[0034] 2. In the hairdresser provided in the embodiment of the present invention, the connection structure avoids the end of the heating plate and connects to the side of the heating plate facing away from the working surface. This design simplifies the visible external structure of the connection structure, making the hairdresser lighter and more beautiful. It also allows for more flexible movement of the heating plate relative to the housing, allowing for vertical and horizontal movement relative to the housing. The user can achieve a good fit between the heating plate and the hairdresser from any angle.

[0035] 3. In the hairdressing device provided in the embodiment of the present invention, at least two connecting structures are provided, and the connecting structures are spaced apart along the central axis of the heating plate. Such connecting structures can firmly connect the housing and the heating plate, help maintain the balance of the heating plate, and ensure that the movement of the heating plate relative to the housing is not restricted.

[0036] 4. In the hair styling device provided in the embodiment of the present invention, when the heating plate rotates relative to the central axis, the height of the insulation gap on one side of the central axis of the heating plate is greater than the height of the insulation gap on the other side of the central axis. This design allows the heating plate to tilt to varying degrees depending on the angle of force applied, thus maintaining consistent grip on the hair regardless of the user's movements, making styling easier.

[0037] 5. In the hair styling device provided in the embodiments of the present invention, at least a portion of the working surface is flat or at least a portion is curved; and / or, one or both of comb teeth and protrusions are provided on the working surface. Different shapes of the working surface can achieve different hair styling effects, such as straightening, curling, and fluffing, to meet the various usage needs of users.

[0038] 6. In the hair styling device provided in the embodiments of the present invention, the connection structure further includes an elastic component and a connecting post. The elastic component includes an elastic member. The elastic member is made of an elastically deformable material. Since the elastic component is connected to the heating plate via the connecting post, when the heating plate is used for hair styling, the elastic member is deformed by force, causing the heating plate to move up and down, left and right, and forward and backward relative to the housing, thereby better adapting to contact with the clamped hair and making the user's hair care movements smoother.

[0039] 7. In the hairdresser provided in the embodiments of the present invention, the connecting post is disposed on the side of the heating plate opposite the working surface and is perpendicular to the working surface. The insulating gap is formed by the connecting post suspending the housing and the heating plate. The connecting post is disposed perpendicular to the working surface, maximizing the floating effect of the heating plate and further simplifying the visible external structure, making the hairdresser more lightweight and aesthetically pleasing.

[0040] 8. In the hairdressing device provided in the embodiment of the present invention, the elastic assembly further includes a heat insulator, one end of which is engaged with the elastic member and the other end is sleeved with a connecting post, which is enclosed within the heat insulator. The connecting post is connected to the heating plate, and some of the heat from the heating plate is transferred to the housing through the connecting post. Enclosing the connecting post with the heat insulator effectively blocks heat transfer, further preventing the housing from overheating.

[0041] 9. In the hair styling device provided in the embodiment of the present invention, support blocks are provided on both sides of the connecting column. The support blocks are used to strengthen the connection between the connecting column and the heating plate, which can reduce the impact of the torsional force on the connection between the connecting column and the heating plate when the heating plate moves relative to the housing, thereby extending the service life of the hair styling device.

[0042] 10. In the hairdressing device provided in the embodiment of the present invention, the end of the elastic component close to the inner surface of the shell is a hemispherical structure. The hemispherical structure allows the elastic component to move in all directions even when it is compressed, making the movement of the heating plate relative to the shell smoother.

[0043] 11. In the hairdresser provided in the embodiments of the present invention, the elastic component and the connecting post are connected by connecting holes, and the elastic component and the connecting post are fixed together by screws engaging the connecting holes. The width of the thermal insulation gap is greater than the distance between the screws and the inner surface of the housing, ensuring that the two clamping plates are fully clamped. When the elastic component is compressed to its maximum extent, the thermal insulation gap still exists, ensuring the thermal insulation effect, while the heating plate can still move up and down and left and right relative to the housing.

[0044] 12. In the hairdressing device provided in the embodiment of the present invention, two longitudinally opposing sides of the heating plate are defined as end faces, and a movable gap is defined between the two end faces and the housing. The width of the movable gap is greater than the distance between the screw and the inner surface of the housing, ensuring that the two clamping plates are fully closed. When the elastic component is compressed to its maximum extent, the movable gap still exists, preventing the ends of the heating plate from abutting the housing, thereby ensuring thermal insulation. At the same time, the heating plate can still move forward and backward relative to the housing.

[0045] 13. In the hairdressing device provided in the embodiment of the present invention, the diameter of the portion of the heat insulating member extending out of the first accommodating space is smaller than the width of the heating plate, so that the connecting structure can be hidden between the shell and the heating plate, making the overall structure of the hairdressing device more simple and beautiful.

[0046] 14. In the hairdressing device provided in the embodiment of the present invention, a first wiring hole is provided on one side of the heating plate where the connecting structure is provided, and a second wiring hole is provided on the heat insulating member. The first wiring hole is connected to the second wiring hole, thereby shortening the wiring distance of the signal connection line for controlling the heating element and hiding it in the elastic component and the connecting structure, eliminating the need for a separate wiring channel, making the entire structure more concise and beautiful.

[0047] 15. The hair styling device provided in the embodiment of the present invention has a groove on its inner side that matches the heating plate, and the heating plate is positioned in the groove. When using the hair styling device, users often press the hair styling device against their scalp to straighten the roots of their hair. Some hair styling devices have no protective heating plates, which can easily cause burns. The heating plate of the hair styling device of the present invention is positioned within the groove, so that the heating plate is partially enclosed by the housing, allowing users to adjust the hair styling device at various angles for hair care without getting burned.

[0048] 16. In the hairdresser provided in the embodiment of the present invention, the depth of the groove is greater than the width of the insulation gap and less than the thickness of the heating plate. This design is understandably more conducive to the user clamping hair, allowing it to more smoothly pass between the two heating plates rather than between the heating plates and the housing. It also ensures that the two heating plates prevent contact and collision with the housing during the clamping operation, which may cause adverse effects.

[0049] 17. The hair styling device provided in the embodiment of the present invention has a through hole on at least one inner side surface, and a negative ion generator is disposed in the first accommodating space. Negative ions generated by the negative ion generator enter the working space through the through hole. During the user's hair care process, the negative ion generator generates negative ions that pass through the through hole area. The generated negative ions are adsorbed by the upper and lower ironing plates and act on the hair, or partially act directly on the hair, to eliminate static electricity, smooth out tangled hair, and make the hair more flat and smooth. A steam generator, atomizer, and fan can also be disposed in the first accommodating space. The steam, spray, and airflow generated by these devices enter the working space through the through hole and are emitted to the area between the heating plates, thereby affecting the hair care process and improving the user experience.

[0050] 18. In the hair styling device provided in the embodiments of the present invention, a through hole is provided on at least one side of the inner side surface of the housing, and the height of the working surface relative to the inner side surface is higher than the height of the through hole relative to the inner side surface. This design allows the steam generated by the steam generator, the negative ions generated by the negative ion generator, the spray generated by the atomizer, and the airflow generated by the fan to better converge near the working surface and act on the hair, thereby improving utilization while also being safer and more comfortable.

[0051] 19. In the hairdressing device provided in the embodiment of the present invention, a second accommodating space is provided in the heating plate, a heating element is provided in the second accommodating space, a PCB board is provided in the shell, a control module is provided on the PCB board, and the control module is connected to the heating element by signal, so that the control module can control the turning on or off of the heating element, which can facilitate user operation. Moreover, the heating element abuts against the heating plate. After the control module controls the heating element to turn on, the heating element quickly transfers heat to the heating plate, thereby reducing the waiting time when the user uses the hairdressing device.

[0052] 20. In the hairdressing device provided in the embodiments of the present invention, an ultrasonic device is provided within the heating plate, and an ultrasonic control circuit is provided within the housing. The ultrasonic control circuit is connected to the ultrasonic device signal. The hairdressing device with ultrasonic function can generate high-frequency shock waves, thereby ultra-micromolecularizing water and protein molecules and directly penetrating the hair layer. When the user uses the hairdressing device, the hair care and nutrient solution on the hair can be more effectively absorbed. Because the hairdressing device of the present invention has an insulating gap, the high-frequency shock waves can cause the heating plate to produce a more obvious vibration effect. Moreover, because the heating plate and the housing are connected only by a connecting structure, its waterproof performance is greatly improved.

[0076] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and implementation examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0077] In this utility model, terms such as "upper," "lower," "left," "right," "front," "back," "top," "bottom," "inner," "outer," "center," "vertical," "horizontal," "transverse," and "longitudinal" indicate positions or locations based on the positions or locations shown in the accompanying drawings. These terms are primarily intended to better describe the utility model and its embodiments and are not intended to limit the devices, elements, or components indicated to having a specific orientation, or to being constructed or operated in a specific orientation.

[0078] Furthermore, the terms "installed," "disposed," "provided with," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0079] See also Figure 2 The first embodiment of the present invention provides a hairdressing device 1, comprising two clamping plates 11 and a handle 12. One end of the two clamping plates 11 is connected to the handle 12, and the handle 12 is used to open and close the clamping plates 11. The clamping plates 11 include a housing 111 and a heating plate 112. A working space 17 is defined between the housings 111 of the two clamping plates 11, and the heating plate 112 is disposed in the working space 17.

[0080] A connecting structure 15 is provided on the side of the heating plate 112 of at least one clamping plate 11 facing the housing 111 of the clamping plate 11. The housing 111 of the clamping plate 11 and the heating plate 112 of the clamping plate 11 are connected by the connecting structure 15, and a thermal insulation gap 13 is formed between the housing 111 of the clamping plate 11 and the heating plate 112 of the clamping plate 11. When the heating plate 112 moves relative to the housing 111, the height of the thermal insulation gap 13 can be reduced.

[0081] It should be noted that at room temperature (20°C), the thermal conductivity of air is only 0.026 W / (m·K), making it an excellent thermal insulation material. In the hair styling device 1 of this embodiment, since there is a thermal insulation gap 13 between the housing 111 and the heating plate 112, air is used as the thermal insulation material. This greatly reduces the amount of heat transferred from the heating plate 112 to the housing 111, thereby preventing burns to the user when touching the housing 111.

[0082] It can be understood that the insulation gap 13 is formed by the shell 111 and the heating plate 112 being suspended and connected through the connecting structure 15. The insulation gap 13 of appropriate width can be obtained by simply adjusting the height of the connecting structure 15 to achieve an ideal insulation effect, facilitate mass production and save costs.

[0083] It can be understood that the connecting structure 15 enables the heating plate 112 to move relative to the shell 111. When the heating plate 112 moves relative to the shell 111, the height of the insulation gap 13 will be reduced. This design enables the heating plate 112 to better adapt to the contact and fit with the clamped hair, making the hair clamped more firmly and enhancing the user experience.

[0084] It can be understood that the handle 12 can realize the opening or closing of the two splints 11. This embodiment does not limit the specific structure of the handle 12. As long as it can realize the opening and closing of the two splints 11, it will not be described in detail here.

[0085] Furthermore, the connecting structure 15 avoids the end of the heating plate 112 and is connected to the side of the heating plate 112 that is away from the working surface 1124. This design simplifies the visible external structure of the connecting structure 15, making the hairdresser 1 more lightweight and beautiful as a whole. It also allows for more flexible movement of the heating plate 112 relative to the housing 111, allowing the user to achieve a good fit with the heating plate 112 at any angle when holding the hair.

[0086] Furthermore, there are at least two connecting structures 15 on the heating plate 112 , and the connecting structures 15 are arranged at intervals along the central axis of the heating plate 112 .

[0087] It is understandable that if the connecting structure 15 is connected to the end of the heating plate 112, the movement of the heating plate 112 will be restricted, and the floating effect cannot be achieved. Therefore, two or more connecting structures 15 are arranged at intervals, rather than directly connected to their ends. This design can firmly connect the housing 111 and the heating plate 112, help the heating plate 112 maintain balance, and ensure that the range of movement of the heating plate 112 relative to the housing 111 is not restricted.

[0088] It is understandable that the connecting structures 15 can be arranged at intervals along the central axis of the length direction of the heating plate 112, or along the central axis of the width direction of the heating plate 112. Due to the support of the connecting structure 15, the heating plate 112 can rotate around the central axis, thereby better clamping the hair from different angles.

[0089] Furthermore, when the heating plate 112 moves relative to the housing 111, the height of the thermal insulation gap 13 on one side of the central axis of the heating plate 112 is greater than the height of the thermal insulation gap 13 on the other side of the central axis. When the heating plate 112 rotates relative to the central axis, the height of the thermal insulation gap 13 on one side of the central axis of the heating plate 112 is greater than the height of the thermal insulation gap 13 on the other side of the central axis.

[0090] It can be understood that during use, this design allows the heating plate 112 to tilt to different degrees depending on the angle of force applied, so that it can continuously clamp the hair without being affected by changes in the user's movements, making it easier for the user to style the hair.

[0091] Please further combine Figure 3 The opposite side of the two heating plates 112 is a working surface 1124 , and the connecting structure 15 includes a connecting column 152 . The connecting column 152 is arranged on a side of the heating plate 112 opposite to the working surface 1124 , and the connecting column 152 is perpendicular to the working surface 1124 .

[0092] It can be understood that the thermal insulation gap 13 is specifically formed by the connecting column 152 suspending and connecting the shell 111 and the heating plate 112. The connecting column 152 is arranged perpendicular to the working surface 1124, which can ensure that the floating effect of the heating plate 112 is maximized relative to the range of movement of the shell 111, and can further simplify the visible external structure, making the hairdressing device 1 more lightweight and beautiful as a whole.

[0093] Furthermore, at least a portion of the working surface 1124 is a plane or at least a portion of a curved surface; and / or, one or both of comb teeth and protrusions are provided on the working surface 1124 .

[0094] It can be understood that in this embodiment, the specific shape of the working surface 1124 of the heating plate 112 is not limited. The working surface 1124 of the heating plate 112 can be a plane, a curved surface, or an irregular surface that interlocks with each other to achieve different hair styling, such as straightening or curling the hair.

[0095] Furthermore, the working surface 1124 may be provided with interlocking comb teeth, protrusions, etc., and the shape of the protrusions may be rectangular, diamond-shaped, spherical, wavy, etc.

[0096] Furthermore, the working surface 1124 may be a combination of comb teeth and protrusions, such as a row of comb teeth is provided on the outer periphery of the working surface 1124 , and protrusions are further provided on the working surface 1124 surrounded by the comb teeth.

[0097] Furthermore, the shapes of the working surfaces 1124 of the two heating plates 112 may be asymmetrical, for example, one working surface 1124 is a plane, and the other working surface 1124 is an irregular surface with protrusions.

[0098] Please further combine Figure 4 Support blocks 11211 are provided on both sides of the connecting column 152. The support blocks 11211 are used to strengthen the connection between the connecting column 152 and the heating plate 112, and can reduce the influence of the torsional force on the connection between the connecting column 152 and the heating plate 112 during the relative movement of the shell 111, thereby extending the service life of the hair styling device 1.

[0099] It can be understood that in this embodiment, there is no specific limitation on the shape and size of the support block 11211 , and there is no specific limitation on the setting direction and number of the support block 11211 on each connecting column 152 .

[0100] Please continue to combine Figures 5 to 7 The connection structure 15 further includes an elastic component 151. The housing 111 defines a first accommodating space 1112. The elastic component 151 is partially located within the first accommodating space 1112 and is connected to the connecting post 152. The elastic component 151 includes an elastic member 1511, which is disposed within the first accommodating space 1112 and connected to the housing.

[0101] Understandably, when a user clamps their hair, each portion of the heating plate 112 clamps a different amount of hair and a different thickness of hair. If the heating plate 112 and the hair were in hard contact, the contact area between the thinner portions and the heating plate 112 would be reduced, resulting in uneven heating of the hair and poor hairdressing results. In this embodiment, since the elastic assembly 151 is connected to the heating plate 112 via the connecting post 152, when the heating plate 112 compresses and straightens the hair, the elastic member 1511 of the elastic assembly 151 is deformed by force, causing the heating plate 112 to move up and down, left and right, and forward and backward relative to the housing 111, thereby better adapting to contact with the clamped hair and making the user's hair care movements smoother.

[0102] For example, see Figures 8a to 8d ,in, Figure 8a The hairdressing device 1 is shown in a naturally closed state, in which the elastic member 1511 is not deformed, the width of the two insulation gaps 13 at the ends away from the handle 12 is 1.5 mm, and the width of the two insulation gaps 13 at the ends close to the handle 12 is 1.1 mm. Figure 8b The figure shows the state of the two heating plates 112 of the hairdressing device 1 moving up and down and forward relative to the housing 111. At this time, the elastic member 1511 is deformed by the force, and the width of the thermal insulation gap 13 changes. At this time, the width of the thermal insulation gap 13 away from the handle 12 is 0.3 mm, and the width of the thermal insulation gap 13 near the handle 12 is 0.5 mm. Figure 8c The figure shows the state of the two heating plates 112 of the hairdressing device 1 moving up and down and to the left relative to the housing 111. At this time, the elastic member 1511 is deformed by the force, and the width of the insulation gap 13 changes. At this time, the widths of the right sides of the two insulation gaps 13 are 0.3 mm and 0.5 mm respectively. Figure 8dThe figure shows the state of the two heating plates 112 of the hairdressing device 1 moving up and down and to the right relative to the housing 111. At this time, the elastic member 1511 is deformed by the force, and the width of the insulation gap 13 changes. At this time, the widths of the left sides of the two insulation gaps 13 are 0.3 mm and 0.5 mm respectively.

[0103] It should be noted that the elastic member 1511 needs to be made of an elastically deformable material, specifically silicone, a spring, a metal spring, etc.

[0104] Furthermore, one end of the elastic component 151 close to the inner surface of the shell 111 is a hemispherical structure. It can be understood that the hemispherical structure allows the elastic component 151 to be subjected to force, and the heating plate 112 can still move in all directions relative to the shell 111, making the movement of the heating plate 112 relative to the shell 111 smoother.

[0105] Furthermore, the elastic component 151 also includes a thermal insulation member 1512, one end of the thermal insulation member 1512 is located in the first accommodating space 1112 and is embedded in the elastic member 1511, and the other end extends out of the first accommodating space 1112 and is socketed with the connecting column 152, and the connecting column 152 is wrapped inside the thermal insulation member 1512.

[0106] It can be understood that the connecting column 152 is connected to the heating plate 112, and part of the heat on the heating plate 112 will be transferred to the shell 111 through the connecting column 152. Wrapping the connecting column 152 with the thermal insulation member 1512 can effectively block the transfer of heat and further prevent the shell 111 from heating up.

[0107] It should be noted that the thermal insulation component 1512 needs to be made of a material with low thermal conductivity and not easy to deform, specifically PET material or TPU material, so that it has good high temperature resistance, can withstand use under high temperature and effectively prevent heat from being transferred to the shell 111.

[0108] Further, see Figure 9 The diameter D1 of the portion of the heat insulating member 1512 extending out of the first accommodating space 1112 (e.g. Figure 9 D1 shown in FIG) is smaller than the width D2 of the heating plate 112 (as shown in FIG). Figure 9 D2) shown in the figure can increase the range of movement of the heating plate 112 relative to the housing 111, and the connecting structure 15 can be hidden between the housing 111 and the heating plate 112, making the overall structure of the hairdressing device 1 more simple and beautiful.

[0109] Please continue reading Figures 3 to 5The elastic component 151 and the connecting column 152 are provided with a connecting hole 1111 that is connected to each other. The elastic component 151 and the connecting column 152 are connected and fixed by screws 18 and the connecting hole 1111, thereby firmly connecting the shell 111 and the heating plate 112. This connection method is simple and reliable, can save process costs, and is convenient for mass production.

[0110] For further information, please refer to Figure 9 , the width L1 of the thermal insulation gap 13 (such as Figure 9 L1 shown in FIG) is greater than the distance L2 between the screw 18 and the inner surface of the housing 111 (as shown in FIG). Figure 9 L2) is provided to ensure that the two clamping plates 11 are completely clamped. When the elastic component 151 is compressed to the maximum extent, the insulation gap 13 still exists, thereby ensuring the insulation effect. At the same time, the heating plate 112 can still move up, down, left and right relative to the shell 111.

[0111] Optionally, in this embodiment, when the two splints 11 are in a naturally closed state, the width of the insulation gap ranges from 1.1 mm to 1.5 mm. When the two splints are fully clamped and the elastic component is compressed to the maximum extent, the width of the insulation gap ranges from 0.3 mm to 0.5 mm.

[0112] Furthermore, please combine Figure 9 and Figure 10 The two opposite sides of the heating plate 112 in the longitudinal direction are defined as end surfaces 1121. There is a movable gap 115 between the two end surfaces 1121 and the housing 111. The width L3 of the movable gap 115 (e.g. Figure 10 L3 shown in FIG) is greater than the distance L2 between the screw 18 and the inner surface of the housing 111 (as shown in FIG). Figure 9 L2) is shown in the figure to ensure that the two clamps are completely clamped. When the elastic component is compressed to the maximum extent, the movable gap 115 still exists, and the two ends of the heating plate 112 will not abut against the shell 111, thereby ensuring the heat insulation effect. At the same time, the heating plate 112 can still move in the front and rear directions relative to the shell 111.

[0113] It is understandable that when the heating plate 112 moves relative to the housing 111 , the elastic member 1511 will be elastically deformed, so the widths of the insulation gap 13 and the movable gap 115 will change with the direction of movement of the heating plate 112 relative to the housing 111 .

[0114] Please further combine Figure 11 The side of the shell 111 facing the working space 17 is defined as an inner side 113 . The inner side 113 is provided with a groove 114 matching the heating plate 112 . The heating plate 112 is disposed in the groove 114 .

[0115] Understandably, when using a hair styling device, users may press the hair styling device 1 against their scalp to straighten their hair roots. Some existing hair styling devices lack protective features on their heating components, making them susceptible to burns. In this embodiment, the heating plate 112 is located within the recess 114, partially encased by the housing 111. This allows users to adjust the hair styling device 1 to various angles for hair care without risk of burns.

[0116] Furthermore, the depth of the groove 114 is greater than the width of the thermal insulation gap 13 in a free state, and less than the thickness of the heating plate 112 .

[0117] It can be understood that such a design is more conducive to the user clamping the hair, and can more smoothly allow the hair to enter between the two heating plates 112 rather than between the heating plates 112 and the shell 111, and can ensure that the two heating plates 112 prevent the two shells 111 from contacting and colliding with each other during the clamping operation, thereby causing adverse effects.

[0118] Please combine Figure 6 and Figure 11 The heating plate 112 has a second accommodating space 1123, which contains a heating element 11231. A PCB 14 is located within the first accommodating space 1112 of one housing 111. A control module (not shown) is located on the PCB 14. The control module establishes a signal connection with the heating element 11231 to control its on and off operation, facilitating user operation. When the control module turns on the heating element 11231, it contacts the heating plate 112, rapidly transferring heat to the heating plate 112. This reduces waiting time for users.

[0119] It can be understood that the heating element 11231 is used to heat the heating plate 112. The heating element 11231 only needs to establish a signal connection with the control component to realize the heating function, and will not be described in detail here.

[0120] Specifically, see Figure 2 In this embodiment, a function button 19 is provided on one of the splints 11. The function button 19 establishes a signal connection with the control module, which can realize the switching and temperature adjustment of the heating element 11231, and divide the adjustable temperature range of the heating element 11231 into multiple gears, which conforms to the user's usage habits and facilitates the user to adjust the temperature according to actual needs.

[0121] It can be understood that the function button 19 only needs to be able to realize the switching and temperature adjustment functions of the heating element 11231, and will not be elaborated here.

[0122] For further information, please refer to Figure 6 and Figure 11A through hole 1131 is provided on at least one inner side surface 113 , and a negative ion generator 11131 is provided in the first accommodating space 1112 . Negative ions generated by the negative ion generator 11131 enter the working space 17 through the through hole 1131 .

[0123] It can be understood that a negative ion needle 11132 is also provided in the first accommodating space 1112. The negative ion needle 11132 is arranged on the clamping plate 11 near the edge of the heating plate 112, so that the negative ions generated by the negative ion needle 11132 and the negative ion generator 11131 can be emitted to the area between the two heating plates 112, so that when the user cares for the hair, the negative ions generated by the negative ion generator 11131 are adsorbed by the upper and lower ironing plates and act on the hair, or partially act directly on the hair, which is used to eliminate static electricity, smooth out messy hair, and make the hair more smooth and smooth.

[0124] It can be understood that through holes 1131 and negative ion needles 11132 are provided on both sides of the inner side surface 113 corresponding to the heating element, and there is no limit to their number.

[0125] Furthermore, in addition to the negative ion generator 11131, the first accommodating space 1112 can also be configured as a steam generating device, an atomizing device and a fan, etc. The steam, spray and air flow generated by them enter the working space 17 through the through hole 1131 and are emitted to the area in the middle of the heating plate 112, thereby affecting the hair care process.

[0126] Furthermore, please combine Figure 3 and Figure 11 The through hole 1131 is disposed on at least one side of the inner side surface 113 of the shell 111 , and a height of the working surface 1124 relative to the inner side surface 113 is higher than a height of the through hole 1131 relative to the inner side surface 113 .

[0127] It can be understood that this design can enable the steam generated by the steam generator, the negative ions generated by the negative ion generator, the spray generated by the atomizer, and the airflow generated by the fan to better converge near the working surface and act on the hair, thereby improving utilization while being safer and more comfortable.

[0128] Please continue reading Figures 3 to 5 The heating plate 112 is provided with a first connection hole 1122 on one side of the connection structure 15 , and the heat insulating member 1512 is provided with a second connection hole 1113 , and the first connection hole 1122 is communicated with the second connection hole 1113 .

[0129] It can be understood that the specific position of the first connection hole 1122 is around the connecting structure 15 close to the handle 12, and the second connection hole 1113 is set on the thermal insulation component 1512. This design makes the wiring distance of the signal connection of the control heating element 11231 shorter, and hides it in the elastic component and the connecting structure, so there is no need to set up a separate connection channel, making the entire structure more simple and beautiful.

[0130] It can be understood that the control module is connected to the heating element 11231 through the first connection hole 1122 and the second connection hole 1113 for signal connection, so as to control the heating element 11231 to be turned on or off.

[0131] See also Figure 12 The second embodiment of the present invention provides another hairdressing device 2 , wherein an ultrasonic device 21 is provided inside the heating plate 112 , and an ultrasonic control circuit (not shown) is provided inside the housing 111 , and the ultrasonic control circuit is connected to the ultrasonic device 21 for signal connection.

[0132] It is understandable that this embodiment does not impose any specific limitation on the ultrasonic device 21 , as long as it can generate high-frequency shock waves that meet the requirements, and specifically can be piezoelectric ceramics, etc.

[0133] It can be understood that the hair styling device 2 with ultrasonic function can generate high-frequency shock waves to make water molecules and protein molecules ultra-micromolecular and directly penetrate into the hair layer. When the user uses the hair styling device 2, the hair care nutrient solution on the hair can be absorbed more effectively.

[0134] It can be understood that, because there is a heat-insulating gap 13 in the hairdressing device 2 in this embodiment, the high-frequency shock wave can make the heating plate 112 produce a more obvious vibration effect, and because the heating plate 112 and the housing 111 are connected only by the connecting structure 15, its waterproof performance is greatly improved.

[0135] It can be understood that the hair styling device 2 in this embodiment also includes all the beneficial effects of the above-mentioned hair styling device 1, which will not be described in detail here.

[0136] Please further combine Figure 13 The third embodiment of the present invention provides another hair styling device 3. The hair styling device 3 is provided with an angled shell 111 on the basis of the hair styling device 1 and the hair styling device 2. The portion of the shell 111 away from the handle 12 is defined as a first portion 31, and the portion of the shell 111 close to the handle 12 is defined as a second portion 32. The heating plate 112 is provided on the first portion 31.

[0137] It can be understood that the angled housing 111 can meet the different usage needs of users. For example, when a professional hairdresser performs hair styling operations on a customer, in order to achieve a better hair styling effect, the wrist will frequently move to find a suitable angle. The hair styling device 3 is provided with an angled housing 111, which can reduce the wrist movement and is more convenient to use.

[0138] It can be understood that in this embodiment, the angle α between the first portion 31 and the second portion 32 (such as Figure 13 The α) shown in is not particularly limited.

[0139] It can be understood that the hair styling device 3 in this embodiment also includes all the beneficial effects of the above-mentioned hair styling device 1 and hair styling device 2, which will not be described in detail here.

[0140] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the principles of the present invention should be included in the scope of protection of the present invention.
