For example, it can be a fixed connection, a detachable connection, or an integral construction; It can be mechanically connected, or electrically connected; It can be directly connected, indirectly through an intermediate medium, or an internal communication between two devices, elements or components. For an ordinary person skilled in the art, specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

Referring to FIG. 2, a first embodiment of the present disclosure provides a hair styling device 1, which includes two clamping plates 11 and a handle 12. One end of the two clamping plates 11 is connected with the handle 12 and is opened and closed through the handle 12. Each clamping plate 11 includes a shell 111 and a heating plate 112. A working space 17 is defined between the shells 111 of the two clamping plates 11, and the heating plates 112 are arranged in the working space 17.

In at least one of the clamping plate 11, a connecting structure 15 is provided between the shell 111 and the heating plate 112 of the clamping plate 11. The shell 111 of the clamping plate 11 is connected with the heating plate 112 of the clamping plate 11 through the connecting structure 15. A heat insulation gap 13 is formed between the shell 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 shell 111, a height of the heat insulation gap 13 can be reduced.

It should be noted that, at room temperature (20° C.), a thermal conductivity of air is only 0.026 W/(m·K). The air is an excellent thermal insulation material, and the hair styling device 1 in this embodiment uses air as a thermal insulation material because there is a heat insulation gap 13 between the shell 111 and the heating plate 112, so that the heat transmitted to the shell 111 by the heating plate 112 is greatly reduced, thus the user is protect from being scalded when touching the shell 111.

Understandably, the heat insulation gap 13 is formed by the shell 111 and the heating plate 112 are connected by the connecting structure 15, and the heat insulation gap 13 of a suitable width can be obtained only by adjusting the height of the connecting structure 15, so as to achieve an ideal heat insulation effect, which is convenient for mass production and manufacturing, and saves cost.

Understandably, the connection structure 15 allows 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 heat insulation gap 13 will be reduced. Such arrangement can make the heating plate 112 better adapt to contact and fit with the hair, so that the hair is clamped more firmly, and the user's use experience is enhanced.

It is understandable that the handle 12 can realize opening or closing of the two clamping plates 11, and the embodiment does not limit the specific structure of the handle 12, as long as the opening and closing between the two clamping plates 11 can be realized, and it will not be repeated herein.

It is understood that the shell 111 can include an upper cover and a lower cover detachably connected with the upper cover. The upper cover together with the lower cover defines a receiving space for receiving internal components. The whole of the shell 111 is made of heat-insulating materials, such as plastic, to isolate heat generated by the internal components of the hair styling device, and prevent the shell 111 from overheating and causing discomfort or scalding to the user.

Further, the connecting structure 15 is connected with one side of the heating plate 112 that avoids the end of the heating plate 112 and is opposite to a working surface 1124 of the heating plate 112. Such design makes simplify visible external structures of the connecting structure 15, makes the hair styling device 1 more lightweight and beautiful, and makes movement of the heating plate 112 more flexible relative to the shell 111, and the user can clamp the hair from any angle and can achieve a better fit between the hair and the two heating plates 112.

Further, please referring to FIG. 10, two opposite sides located in the length direction of the heating plate 112 are defined as end faces 1121. There is a movement gap 115 between each of the two end faces 1121 and the shell 111.

Understandably, the movement gap 115 ensures the two ends of the heating plate 112 will not be butted against the shell 111, so that the heat insulation effect is guaranteed, and the heating plate 112 can still move in the front and rear directions relative to the shell 111 simultaneously, the heating plate 112 can better adapt to contact and fit with the clamped hair.

Please continue to refer to FIG. 3 to FIG. 5, a side of the heating plate 112 where the connecting structure 15 is arranged is provided with a first wiring hole 1122, the connecting structure is provided with a second wiring hole 1113, and the first wiring hole 1122 is communicated with the second wiring hole 1113.

Understandably, the first wiring hole 1122 is positioned around the connecting structure 15 adjacent to the handle 12, and such design makes a line routing distance of the signal connection for controlling the heating piece 11231 shorter, and hides lines in the elastic component and the connecting structure, and does not need to separately arrange a connecting channel for the lines, so that the whole structure is more concise and beautiful.

Further, the two ends of the heating plate 112 located in length direction are not in contact with the shell 111.

Understandably, such design can ensure the movement of the heating plate 112 flexible relative to the shell 111, and can ensure the heating plate 112 and the shell 111 are only connected through a connecting structure 15, avoiding the connection design of the end of the heating plate 112 and the shell 111 in the traditional design, further reducing the possibility of heat transfer on the heating plate 112 to the shell 111, improving the anti-scalding effect, and making the overall structure more smoother and more beautiful.

Further, the number of the connecting structures 15 on each heating plate 112 is at least two, and the at least two connecting structures 15 are arranged at intervals along a central axis of the heating plate 112.

Understandably, if the connecting structure 15 is connected with the end of the heating plate 112, movement of the heating plate 112 is restricted, so that a floating effect cannot be achieved. Therefore, two or more connecting structures 15 are arranged at intervals to connect the heating plate 112 with the shell 111, instead of directly connecting the heating plate 112 with the shell 111 with their ends. Such design can have the heating plate 112 firmly connected with the shell 111. It is conducive to maintaining balance of the heating plate 112 and ensuring a movement range of the heating plate 112 relative to the shell 111 not limited simultaneously.

Understandably, the connecting structure 15 can be arranged at intervals along the central axis of a length direction of the heating plate 112, and can also be arranged at intervals along the central axis of a width direction of the heating plate 112. Due to support of the connecting structure 15, the heating plate 112 can rotate around the central axis, so that the hair can be better clamped from different angles.

Further, the heating plate 112 moves relative to the shell 111, and the height of the heat insulation gap 13 on one side of the central axis of the heating plate 112 is greater than the height of the heat insulation gap 13 on the other side of the central axis. When the heating plate 112 rotates around the central axis, the height of the heat insulation gap 13 on one side of the central axis of the heating plate 112 is greater than the height of the heat insulation gap 13 on the other side of the central axis.

Understandably, during the process of use, such design makes the heating plate 112 incline at different angles along with different force applied thereon, which can keep clamping the hair for styling without being affected by the change of the user's action.

Please further referring to FIG. 3, opposite sides of the two heating plates 112 are the working surfaces 1124. Each connecting structure 15 includes a connecting column 152. The connecting column 152 is provided at 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.

Understandably, specifically, the heat insulation gap 13 is formed by a suspension connection between the shell 111 and the heating plate 112 by the connecting column 152, and the connecting column 152 is arranged perpendicular to the working surface 1124, so that the floating effect of the heating plate 112 can be achieved to maximize the movement range of the heating plate 112 relative to the shell 111. Furthermore, visible structures of the hair styling device can be further simplified, so that the hair styling device 1 is more lightweight and beautiful.

Furthermore, at least part of the working surface 1124 is flat or curved; and/or, one or two of comb teeth and protrusions are arranged on the working surfaces 1124.

Understandably, in the embodiment, the shape of the working surface 1124 of the heating plate 112 is not limited, and the working surfaces 1124 of the heating plates 112 can be a plane, a curved surface or an irregular surface engaged with each other, so as to realize different hair styles, such as straightening, curling hair, etc.

Further, the comb teeth, the protrusions and the like that are engaged with each other can also be arranged on the working surfaces 1124, and the shape of the protrusions can be rectangular, diamond-shaped, spherical, wavy-shaped and the like.

Further, the working surfaces 1124 can be a combination of the comb teeth and the protrusions, such as arranging a row of comb teeth around an outer periphery of the protrusions on the working surfaces 1124.

Further, the shape of the working surfaces 1124 of the two heating plates 112 can be asymmetrically arranged, such as one of the working surfaces 1124 is a plane, and the other of the working surfaces 1124 is provided with an irregular surface with protrusions.

Please further referring to FIG. 4, two sides of the connecting column 152 are provided with supporting blocks 11211, and the supporting blocks 11211 are used for strengthening the connection between the connecting column 152 and the heating plate 112, which can weaken the influence that a torsion force generated by the movement of the heating plate relative to the shell applied on connection points between the connecting column 152 and the heating plate 112, thus prolonging the service life of the hair styling device 1.

Understandably, in the embodiment, the shape and size of the support block 11211 are not specifically limited, and arranging directions and the number of the support blocks 11211 on each connecting column 152 are not specifically limited.

Further, the connecting structure 15 at least partially an elastic structure. When the heating plates 112 are clamping hair, the connecting structure 15 is subjected to force, the elastic part will be deformed, so that the heating plate 112 can move relative to the shell 111 and the movement of the heating plate 112 relative to the shell 111 is smoother, which can provide users with a better hair styling experience.

Please continue to referring to FIG. 5 to FIG. 7, the connecting structure 15 further includes an elastic component 151, the shell 111 is provided with a first accommodating space 1112, the elastic component 151 is partly located in the first accommodating space 1112, and the elastic component 151 is connected with the connecting column 152. The elastic component 151 includes an elastic piece 1511 arranged in the first accommodating space 1112 and connected with the shell.

Understandably, in the process of clamping hair, the amount and thickness of hair clamped by each part of the heating plate 112 may be different. If the heating plate 112 is directly pressed on the hair, the contact area of the hair with smaller thickness with the heating plate 112 is reduced, so that the hair is heated unevenly, and the hair styling effect is not good. In the embodiment, because the elastic component 151 is connected between the connecting column 152 and the heating plate 112, the elastic component 151 will be forced to deform to allow the heating plate 112 to move upwards or downwards, leftwards or rightwards, forward or backward relative to the shell 111 when the heating plate 112 performs operations of clamping and straightening the hair, thus better adapting to the contact with clamped hair, which is beneficial for the user to care for the hair more smoothly.

As an example, referring to FIG. 8a to FIG. 8d, FIG. 8a shows the hair styling device in a natural closed state in which the elastic piece 1511 is not deformed, and the width of the two heat insulation gaps 13 at an end away from the handle 12 is 1.5 mm, and the width of the two heat insulation gaps 13 at an end adjacent to the handle 12 is 1.1 mm. FIG. 8b shows the state when the two heating plates 112 of the hair styling device 1 move upward and downward and forward relative to the shell 111, the elastic pieces 1511 are deformed by force at this moment, and the width of the heat insulation gap 13 changes, at this moment, the width of the heat insulation gap 13 at the end away from the handle 12 is 0.3 mm, and the width of the heat insulation gap 13 at the end adjacent to the handle 12 is 0.5 mm. FIG. 8c shows the state when the two heating plates 112 of the hair styling device 1 move upward and downward and leftward relative to the shell 111, and the elastic pieces 1511 are deformed by force at this moment, and the width of the heat insulation gap 13 changes, and the width of the right side of the two heat insulation gaps 13 is 0.3 mm and 0.5 mm respectively. FIG. 8d shows the state when the two heating plates 112 of the hair styling device 1 move upward and downward and rightward relative to the shell 111, and the elastic pieces 1511 are deformed by force at this moment, and the width of the heat insulation gap 13 changes, and the width of the left side of the two heat insulation gaps 13 is 0.3 mm and 0.5 mm respectively.

It should be noted that the elastic pieces 1511 should be made of elastic deformation materials, specifically silicone, springs, metal sheets, etc.

Further, an end of the elastic component 151 facing the inner surface of the shell 111 is a hemispherical structure. It is understandable that the hemispherical structure can make the heating plate 112 move in all directions relative to the shell 111 under the condition that the elastic component 151 is pressed, so that the movement of the heating plate 112 relative to the shell 111 is smoother.

Further, each elastic component 151 further includes a heat insulation piece 1512. One end of the heat insulation piece 1512 is located in the first accommodating space 1112 and is embedded with the elastic piece 1511, the other end extends out of the first accommodating space 1112 and sleeves on the connecting column 152, and the connecting column 152 is wrapped inside the heat insulation piece 1512.

Understandably, the connecting column 152 is connected with the heating plate 112, and part of the heat from the heating plate 112 can be transmitted to the shell 111 through the connecting column 152. The connecting column 152 is wrapped inside the heat insulation piece 1512, which is beneficial to prevent the heat from being transmitted to the shell effectively, thus further prevent the shell 111 from overheating.

It should be noted that the heat insulation piece 1512 should be made of materials with low thermal conductivity and not easy to deform. Specifically, the heat insulation piece 1512 can be made of PET material or TPU material, which can resist high temperature and can effectively block heat transmission to the shell 111.

Further, referring to FIG. 9, a diameter D1 of the part of the heat insulation 1512 extending out of the first accommodating space 1112 (D1 shown in FIG. 9) is smaller than the width D2 of the heating plate 112 (D2 shown in FIG. 9), which can increase the movement range of the heating plate 112 relative to the shell 111. The connecting structure 15 can be hidden between the shell 111 and the heating plate 112, so that the overall structure of the hair styling device 1 is more simplified and beautiful.

Please continue to refer to FIG. 3 to FIG. 5, both the elastic component 151 and the connecting column 152 are provided with connecting holes 1111 communicated with each other. The elastic component 151 and the connecting column 152 are connected and fixed by engaging screws into the connecting holes 1111, thereby firmly connecting the shell 111 with the heating plate 112. Such connection way is simple and reliable, which can save process cost, and is convenient for mass production.

Furthermore, please continue to refer to FIG. 9, the width L1 of the heat insulation gap 13 (L1 as shown in FIG. 9) is greater than the distance L2 between the screws 18 and the inner surface of the shell 111 (L2 as shown in FIG. 9), so as to ensure that the two clamping plates 11 are completely clamped. When the elastic component 151 is compressed to a maximum extent, the heat insulation gap 13 still exists, and the thermal insulation effect is ensured, and the heating plate 112 can still move upward-downward, leftward-rightward relative to the shell 111 simultaneously.

Optionally, in the embodiment, when the two clamping plates 11 is in the natural closed state, the width of the heat insulation gap is in the range of 1.1 mm˜1.5 mm, the two clamping plates are completely clamped; and when the elastic components are compressed to the maximum extent, the width of the thermal insulation gap is 0.3 mm˜0.5 mm.

Furthermore, please referring to FIG. 9 and FIG. 10, the width L3 of the movement gap 115 (L3 shown in FIG. 10) is greater than the distance L2 between the screw 18 and the inner surface of the shell 111 (L2 as shown in FIG. 9), which ensures that the two clamping plates are completely clamped. When the elastic component is compressed to the maximum extent, the movement gap 115 still exists, and the two ends of the heating plate 112 will not be butted against the shell 111, so that the heat insulation effect is guaranteed, and the heating plate 112 can still move in the front and rear directions relative to the shell 111 simultaneously.

It is understandable that when the heating plate 112 moves relative to the shell 111, because the elastic piece 1511 will be deformed, the width of the heat insulation gap 13 and the movement gap 115 will change along with the direction in which the heating plate 112 moves relative to the shell 111.

Please further referring to FIG. 11, a side of the shell 111 facing the working space 17 is defined as the inner surface 113. The inner surface 113 defines a recess 114 matching the heating plate 112, and the heating plate 112 is arranged at the recess 114.

It is understandable that in the process of using the hair styling device, in order to straighten hair roots, the hair styling device 1 may be pressed against the scalp, and heating parts of some existing hair styling devices do not have any protective structures, thus prone to cause burns. In this embodiment, the heating plate 112 is located in the recess 114, so that the heating plate is half-wrapped by the shell 111, and the user can adjust various angles of the hair styling device 1 for hair care without being burned.

Furthermore, in the original state, the depth of the recess 114 is greater than the width of the heat insulation gap 13, and is smaller than the thickness of the heating plate 112.

Understandably, such arrangement is convenient for the user have the hair more smoothly entering the working space between the two heating plates 112 instead of between the heating plate 112 and the shell 111, and can ensure that the two shells 111 are prevented from contacting and colliding with each other to produce adverse effects when the two heating plates 112 are clamped with each other.

Please referring to FIG. 6 and FIG. 11, a second accommodating space 1123 is defined in the heating plate 112, and a heating piece 11231 is arranged in the second accommodating space 1123. A PCB board 14 is arranged in the first accommodating space 1112 of one of the shells 111, and a control module (not shown) is arranged on the PCB board 14. The control module establishes a signal connection with the heating piece 11231 to control on and off of the heating piece, which is convenient for the user to operate. After the control module controls the heating piece 11231 to be turned on, the heating piece 11231 contacts the heating plate 112 to quickly transmit heat to the heating plate 112, thus reducing waiting time to use.

It is understandable that the heating piece 11231 is used for heating the heating plate 112, as long as the heating piece 11231 can establish a signal connection with the control module to achieve a heating function, and it will not be repeated here.

Specifically, referring to FIG. 2, in the embodiment, a function button 19 is arranged on one of the clamping plates 11. The function button 19 can establish a signal connection with the control module to achieve turning on and off the heating piece 11231 and regulating temperature of the heating piece 11231. The temperature of the heating piece 11231 can be divided into multiple ranges, which conforms to the user's use habits, and is convenient for the user to regulate temperature according to actual needs.

Understandably, as long as the function button 19 can realize switching on and off of the heating piece 11231 and regulating temperature of the heating piece 11231, detailed arrangements and structures will not be repeated here.

Specifically, the first wiring hole 1122 is positioned around the connecting structure 15 adjacent to the handle 12, and the second connecting hole 1113 is arranged on the heat insulation piece 1512. The control module is in a signal connection with the heating piece 11231 through the first wiring hole 1122 and the second wiring hole 1113, and is used for controlling switching on and off of the heating piece 11231.

Further, please referring to FIG. 6 and FIG. 11, at least one inner surface 113 is provided with a through hole 1131, the first accommodating space 1112 is provided with an anion generator 11131, and anions generated by the anion generator 11131 can enter the working space 17 from the through hole 1131.

Understandably, an anion needle 11132 is arranged in the first accommodating space 1112. The anion needle 11132 is arranged at a position on the clamping plate 11 adjacent to an edge of the heating plate 112, so that the anions generated by the anion needle 11132 and the anion generator 11131 can be emitted to the area between the two heating plates 112. Therefore, in the process of caring for the user's hair, the anions generated by the anion generator 11131 are adsorbed on the hair by the two heating plates or partially act directly on the hair, which can eliminate static electricity, smooth messy hair, and make hair softer and smoother.

It can be understood that both sides of the inner surface 113 corresponding to the heating piece are provided with through holes 1131 and anion needles 11132, the number of which are not limited.

Furthermore, in addition to the anion generator 11131, the first accommodating space 1112 further can be provided with a steam generating device, an atomizing device, a fan, etc, steam, spray and air flow generated by which enter the working space 17 through the through holes 1131 and are emitted to the area between the heating plates 112, so as to have an effect on the hair care process.

Furthermore, with reference to FIG. 3 and FIG. 11, the through hole 1131 is arranged on at least one side of the inner surface 113 of the shell 111, and the height of the working surface 1124 relative to the inner surface 113 is higher than the height of the through hole 1131 relative to the inner surface 113.

It can be understood that this design allows steam generated by the steam generating device, negative ions generated by the anion generator, spray generated by the atomizing device, and airflow generated by the fan to better converge near the working surface and act on the hair, improving efficiency while being safer and more comfortable.

Referring to FIG. 12, a second embodiment of the present disclosure provides another hair styling device 2, the heating plate 112 is provided with an ultrasonic device 21, an ultrasonic control circuit (not shown) is arranged in the shell 111, and the ultrasonic control circuit is in a signal connection with the ultrasonic device 21 signal.

Understandably, in the embodiment, it does not make a specific limitation on the ultrasonic device 21, as long as it can produce a high-frequency vibration wave that satisfies user's demand. Specifically, it can be piezoelectric ceramics or the like.

Understandably, the hair styling device with an ultrasonic function can generate high-frequency vibration waves so that the ultra-fine molecules of water and protein molecules can penetrate directly into the hair layer, and the hair care solution can be absorbed more effectively when the user uses the hair styling device 2.

Understandably, because there is a heat-insulation gap 13 in the hair styling device 2 in the embodiment, the high-frequency vibration wave can make the heating plate 112 produce a more obvious vibration effect, and because the heating plate 112 and the shell 111 are only connected through a connecting structure 15, its waterproof performance is greatly improved.

It is understandable that the hair styling device 2 in the present embodiment also includes all beneficial effects of the hair styling device 1, which will not be repeated herein.

Please further referring to FIG. 13, a third embodiment of the present disclosure provides another hair styling device 3. The hair styling device 3 is provided with a shell 111 bended at an angle on the basis of the hair styling device 1 and the hair styling device 2. A part of the shell 111 that is far away from the handle 12 is a first part 31, a part of the shell 111 adjacent to the handle 12 is a second part 32, and the heating plate 112 is arranged on the first part 31.

It is understandable that the shell 111 bended at an angle can meet different user' needs. For example, when a professional hair dresser using the styling tool 3 to perform hair styling operations on a customer, in order to achieve better styling effect, his wrist will move frequently to find a suitable angle for operations. The shell 111 of the hair styling device 3 is bended at the angle, which can reduce its wrist actions, and is more convenient for operations.

Understandably, the angle α between the first part 31 and the second part 32 (as a shown in FIG. 13) is not specifically qualified in the present embodiment.

Understandably, the hair styling device 3 in this embodiment also includes all the beneficial effects of the hair styling device 1 and the hair styling device 2, which are not repeated herein.

The foregoing is only a better embodiment of the present disclosure and is not used to limit the present disclosure, and any modifications, equivalent substitutions and improvements, etc., made within the principles of the present disclosure shall be included in the scope of protection of the present disclosure.
