Description

Flexible hair styling device and heating device thereof

Technical Field

The utility model relates to the technical field of hair styling devices, in particular to a flexible hair styling device and a heating device thereof.

Background

At present, the hair straightener has wide application in the hairdressing industry and can be used for straightening hair. Since the heating plates of existing hair straighteners are typically made of rigid materials such as rigid metals, ceramics, or a combination of both, a rigid structure is formed. Sometimes, a spring or silica gel is arranged in the shell for supporting the bottom of the heating plate assembly, so that the heating plate assembly can move up and down or swing integrally when being stressed, but the whole heating plate is of a rigid structure, so that the clamping pressure of the hair straightener cannot be excessively high when hair is pulled, the hair cannot be clamped and cannot slide due to the high clamping pressure, and pain is caused to a user. Meanwhile, the rigid heating plate can clamp and disperse hair when the hair is clamped and pulled, the hair cannot be well wrapped, heat of the heating plate cannot be uniformly and rapidly transferred to the hair, the hair pulling efficiency is reduced, and the effect is poor.

Therefore, the Chinese patent application with publication number of CN114732201A discloses a hair straightener with a heating plate capable of being elastically bent and deformed, which comprises a shell, a power line component, a heating plate component, a control switch and a circuit board, wherein the heating plate component comprises a heating plate and a heater, the heater is horizontally arranged on a plurality of supporting blocks, and the supporting blocks are arranged on a fixing frame through supporting legs at two ends; an elastic rubber seat is arranged in the fixing frame, and the supporting block is arranged above the elastic rubber seat; a plurality of U-shaped brackets are paved on the heater, and the heating plate is paved on the U-shaped brackets. According to the prior art, the U-shaped support, the supporting block and the elastic rubber seat are designed as the main supporting structure, the heating plate and the heater are installed and fixed through the supporting structure, and the heating plate can generate local elastic bending deformation along the pulling direction during pulling, so that the hair can not be clamped to be pulled smoothly and the pain sense can be generated due to overlarge clamping pressure, meanwhile, the heating plate can better wrap the hair, heat energy is more uniformly and effectively directly transferred to the hair, and the pulling effect and experience are improved. Although this prior art realizes better flexible hair straightening effect through setting up multistage elastic support, still there is following not enough: although the elastic support is realized by the support blocks with multiple sections, the effect of flexibly clamping hair can be seemingly realized by the sectional stress, but the heating plate, the U-shaped support and the heater are of an integral structure, and even if the thickness is reduced, the flexibility of the integral structure after lamination is still insufficient, and particularly, the volume thickness of the heater is required to be large enough to obtain larger heat, otherwise, the heating efficiency is very slow.

Therefore, the key to better achieve the flexible clamping effect with the hair is how to solve the problem of insufficient overall flexibility after the combination of the heating plate, the U-shaped bracket and the heater in the prior art.

Embodiment 1, as shown in fig. 1 to 3, a heating apparatus has a first heat generating component 1 and a second heat generating component 2 arranged side by side in front of and behind each other, and the surfaces of the first heat generating component 1 and the second heat generating component 2 are covered with a first heat conductive sheet 3. When the first heat conducting fin 3 above the first heat generating component 1 is pressed, the pressed first heat conducting fin 3 and the first heat generating component 1 move downwards, and the second heat generating component 2 is driven to move downwards due to the integral structure of the first heat conducting fin 3, however, the downward stroke of the second heat generating component 2 is smaller than that of the first heat generating component 1, so that the surface of the first heat generating component 1 is lower than that of the second heat generating component 2, and therefore, a local suspension gap is formed between the first heat generating component 1 and the first heat conducting fin 3, and particularly, the suspension gap at a position close to the second heat generating component 2 is larger. Thanks to the suspension gap, the flexible heat conducting fin has better deformation space. In addition, the second heat generating component may be replaced with a floatable support for a non-heat generating component.

In this embodiment 1, the second heat generating component 2 is movable, in embodiment 2, as shown in fig. 4, the second heat generating component 2 may be fixed, and although the second heat generating component 2 is fixed, the first heat conducting fin 3 corresponding to the second heat generating component 2 loses the effect of flexible contact, the second heat generating component 2 may be used as the heat supplement of the first pair of heat conducting fins, that is, the first heat conducting fin 3 corresponding to the first heat generating component 1 is used as the position of flexible contact, and due to the generation of the suspension gap (after the second heat generating component 2 is fixed, the suspension gap is larger), so that the contact surface between the first heat conducting fin 3 and the first heat generating component 1 is reduced, and the first heat conducting fin 3 corresponding to the suspension gap loses direct contact with the first heat generating component 1 and loses direct heat conduction, so that the fixed second heat generating component 2 can also perform heat supplement to compensate for the defect caused by the suspension gap. Alternatively, the second thermal assembly 2 may be replaced with a fixed, non-heat generating assembly support.

In embodiment 10, as shown in fig. 17, two heating devices are used to form a clamping surface, the upper heating device has a first heat conducting strip 3 and a first heating element 1 and a second heating element 2 which are arranged side by side in front of and behind each other, the lower heating device has a first heat conducting strip 3 and a first heating element 1 and a second heating element 2 which are arranged side by side in front of and behind each other, and the length dimensions of the first heating element 1 and the second heating element 2 are the same in the upper and lower directions, and the upper and lower gaps are formed in the middle. In embodiment 11, as shown in fig. 18, on the basis of embodiment 10, the first heating element 1 of the upper heating device is shorter, the second heating element 2 is longer in length, the upper slit is formed on the left side, the first heating element 1 of the lower heating device is longer in length, the second heating element 2 is shorter in length, and the lower slit is formed on the right side. In embodiment 12, as shown in fig. 19, the upper heating device is configured by sequentially arranging the first heat conductive sheet 3 and the first heating element 1, the second heating element 2 and the third heating element 4 in a front-to-rear direction, the lower heating device is configured by arranging the first heat conductive sheet 3 and the first heating element 1 and the second heating element 2 in a front-to-rear direction, the lower gap of the lower heating device is located in the middle, and the two upper gaps of the upper heating device are located on the left and right sides. Through the pairing combination of the upper gap and the lower gap, the configuration of clamping forces at different positions is realized, and a person skilled in the art can randomly combine and realize the control design of the clamping forces of different clamping surfaces according to the scheme, so that the scheme is extended and the scheme is within the protection scope.

In addition to the above embodiments, the number and the size of the heat generating components may be changed to evolve more combinations, and then the coverage range of the heat conducting fin may be changed to evolve more combinations, so that the evolved structure based on the concept is all extended in the scope of the concept, and should be within the scope of protection of the concept, which is not described herein.

In embodiment 14, as shown in fig. 21, the heating element 7 is supported by a single elastic member 8, the elastic member 8 is disposed in the middle of the bottom surface of the heating element 7, and since only one elastic member 8 provides elastic supporting force, it is necessary to provide reliable structure for assembling the elastic member 8, for example, the upper and lower ends of the elastic member are respectively assembled and fixed by a silica gel supporting block, one of the elastic members is assembled in place with the middle of the bottom surface of the heating element 7, so that the heating element 7 can float in multiple directions around the silica gel supporting block, including front-back floating at two ends of the heating element, left-right floating at two sides, and so on.

In embodiment 15, as shown in fig. 22, in order to make the floating effect of the heating element 7 more reliable and stable, two elastic members 8 are generally used to support the heating element 7 together, and one elastic member 8 is generally disposed under the bottom surface near each of the two ends according to the length extending direction. As shown in fig. 23, in order to enhance the effect of the multidirectional floating, the bottom surface of the elastic member 9 is provided with an arc supporting surface, which contributes to the floating effect of the heat generating component 7 on the left and right sides.

For example, an inclined heat generating component, which generates a position of partially arching the heat conductive sheet in the middle when the first heat generating component 1 and the second heat generating component 2 are elevated toward the center, so that the holding force at this position is more enhanced. Of course, the position-adjustable elastic piece 8 can also be used for adjusting different clamping force requirements, so that the application range is improved.

Besides the arrangement positions of the elastic pieces in the above embodiments, the elastic pieces may be disposed on the left and right sides of the bottom surface of the heating element, or the side surfaces of the heating element are connected by tension springs to realize floating, which is also realized by those skilled in the art, and the specific structure is not described herein again.
