[0070] As part of the creative concept of the present application, before describing the embodiments of the present application, it is necessary to analyze the causes of the problems in the related art that the air outlet of the hair-drying styling device is not conducive to styling, and the temperature of the metal sheet on the surface of the hair straightener clamp is uneven, which affects the effect of heating and deformation of the hair, and the technical solution of the embodiments of the present application is obtained through reasonable analysis.

[0071] In the related art, styling equipment is used to style hair. Styling equipment includes but is not limited to hair straighteners, electric clamps, hair dryers and other hairdressing tools. Among them, the core technology of the styling equipment is to heat the heating element by electric current, and then transfer the heat to the aluminum plate or ceramic plate to make it generate heat. When the hair passes over these heating plates, it will be heated and softened into shape. In order to make the styling equipment multifunctional, the heating component is installed in the hair straightener or electric clamp to provide a hot air flow. However, in the prior art, the heating component is designed to be cylindrical or conical, so that the air outlet of the hair-drying styling equipment is circular, and the wind blown out of the circular air outlet is relatively concentrated, and the area swept by the wind is small, which is not conducive to styling the hair.

[0072] To this end, the present application provides a heating component. The heating component includes a shell and a heating wire; the shell is a long strip structure extending along a first direction, and the shell has an air inlet arranged in a second direction and an air outlet arranged in a third direction, wherein the second direction is perpendicular to the first direction, the third direction is perpendicular to the first direction, and the third direction is not parallel to the second direction. By setting the opening directions of the air inlet and the air outlet to be non-parallel, the flow direction of the gas flowing out through the air outlet after entering the heating component from the air inlet is changed. The air inlet and the air outlet are both extended in the first direction, the heating wire is extended in the first direction, and the heating wire is arranged between the air inlet and the air outlet; wherein the gas flowing in from the air inlet can be heated by the heating wire and discharged through the air outlet. By setting the air inlet and the air outlet to be extended in the first direction, the cross section of the air flow blown out from the air outlet is long strip-shaped, and the area swept by the long strip air flow is large, which improves the effect of styling hair.

[0073] The technical solutions of the embodiments of the present application are described in detail below in conjunction with the accompanying drawings. The technical features involved in the different implementation modes of the present application described below can be combined with each other as long as there is no conflict between them.

[0074] For reference Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the heating component provided in some embodiments of the present application. Figure 2 A schematic structural diagram of a shell of a heating component provided in some embodiments of the present application.

[0075] In an embodiment of the present application, a heat generating component is provided. Figure 1 and Figure 2 As shown, the heat generating assembly includes a housing 1. The housing 1 is used to accommodate other components, for example, to accommodate components that can generate heat or heat.

[0076] Specifically, the housing 1 is in a long strip structure extending along the first direction. Exemplarily: the housing 1 is in a rectangular parallelepiped structure, the housing 1 is in an elliptical column structure. The embodiment of the present application is described by taking the housing 1 in a rectangular parallelepiped structure as an example.

[0077] First, by setting the housing 1 to be a long strip structure extending along the first direction, the heating component as a whole is a long strip structure. The heating component integrates multiple components into an overall structure, which is convenient for assembling the overall structure with other devices. For example, the heating component is installed on a hair straightener, the heating component is installed on a hair dryer, etc. At the same time, the overall structure installation improves the assembly efficiency compared with the installation of multiple scattered components.

[0078] Secondly, the long strip structure is relatively compact and linear. The layout of the long strip structure is relatively simple and direct, and there is no need to reserve too much gap or space to adapt to other shapes, which is easy to assemble.

[0079] Therefore, the long strip structure is more efficient in space utilization, and can maximize the use of limited linear space and reduce space waste. Therefore, the heating component set as a long strip structure is easy to install on other devices. Installing the heating component with a long strip structure on a hair straightener can reduce the size of the product. Installing the heating component with a long strip structure on a hair dryer can achieve a better styling effect without installing a straight-line concentrated air nozzle.

[0080] The housing 1 has an air inlet 12 arranged in the second direction and an air outlet 13 arranged in the third direction. Figure 1 The second direction is perpendicular to the first direction, the third direction is perpendicular to the first direction, and the third direction is not parallel to the second direction. By setting the second direction to be perpendicular to the first direction, the third direction to be perpendicular to the first direction, and the third direction to be not parallel to the second direction, the flow direction of the gas is changed, so that the gas enters the heating component from the air inlet 12, and can be discharged from the air outlet 13 in a preset direction after being evenly heated.

[0081] The air inlet 12 and the air outlet 13 both extend in the first direction, so that the air inlet 12 and the air outlet 13 are long strip structures, for example: the air inlet 12 and the air outlet 13 are rectangular structures, the air inlet 12 and the air outlet 13 are elliptical structures. The embodiment of the present application is described by taking the air inlet 12 and the air outlet 13 as a rectangular structure as an example.

[0082] By arranging the air inlet 12 and the air outlet 13 to extend along the first direction, the cross-section of the wind blown out from the air outlet 13 is in the shape of an elongated strip. Combined with the user's swinging, the wind blown out from the straight-line air outlet 13 sweeps over a larger blowing area, thereby improving the hair styling effect.

[0083] The heating component also includes a heating wire 2. The material type of the heating wire 2 is not limited in the embodiment of the present application, and it can be a material that has good heating efficiency, can quickly reach the required temperature, has stable performance, and can maintain stable heating during long-term use, such as nickel-chromium alloy, iron-chromium-aluminum alloy, constantan, etc. In the embodiment of the present application, the material type of the heating wire is nickel-chromium alloy as an example for explanation.

[0084] Specifically, the heating wire 2 is extended along the first direction, and the heating wire 2 is arranged between the air inlet 12 and the air outlet 13 .

[0085] During the operation of the heating component, the gas flowing in from the air inlet 12 can be heated by the heating wire 2 and discharged through the air outlet 13 .

[0086] In the above technical solution, the heating wire 2 is arranged to extend along the first direction, and the heating wire 2 is arranged between the air inlet 12 and the air outlet 13, so that the gas entering from the air inlet 12 can be evenly heated and then discharged through the air outlet 13, so that the temperature of the gas discharged from the air outlet 13 is relatively uniform.

[0087] In the embodiment of the present application, the housing 1 includes two support frames 14. The support frames 14 are used to support the overall frame of the housing 1 or the structure inside the housing 1.

[0088] Specifically, the two support frames 14 are arranged opposite to each other along the first direction.

[0089] The housing 1 further comprises an outer wall 15. The outer wall 15 and the two support frames 14 surround a heating zone, the heating wire 2 is connected between the two support frames 14, and the heating wire 2 is located in the heating zone.

[0090] The air inlet 12 and the air outlet 13 are formed on the outer wall 15 .

[0091] As an optional technical solution, the length of the heating wire 2 along the first direction, the length of the air inlet 12 along the first direction, and the length of the air outlet 13 along the first direction are equal.

[0092] As another optional technical solution, the length of the heating wire 2 along the first direction is greater than the length of the air inlet 12 along the first direction, and the length of the heating wire 2 along the first direction is greater than the length of the air outlet 13 along the first direction.

[0093] In the above technical solution, the outer wall 15 and the two support frames 14 are surrounded by a heating zone, and the heating wire 2 is connected between the two support frames 14. Since the heating wire 2 is extended along the first direction and is arranged between the air inlet 12 and the air outlet 13, one side of the heating wire 2 is arranged opposite to the air inlet 12, and the other side of the heating wire 2 is arranged opposite to the air outlet 13, and then the gas flowing in from the air inlet 12 will flow through the heating zone around the heating wire 2, so that the temperature is increased after being heated by the heating wire 2, and then it flows out from the air outlet 13, so that the temperature of the gas flowing out at the air outlet 13 is more uniform, thereby improving the modeling effect.

[0094] A guide surface 16 is disposed on one side of the outer wall 15 opposite to the air inlet 12 , wherein the guide surface 16 is configured to guide the gas to flow from the air inlet 12 to the air outlet 13 .

[0095] Specifically, the guide surface 16 is an inclined surface provided on the inner side surface of the outer wall 15. During the operation of the heating component, the gas flowing in from the air inlet 12 is heated by the heating wire 2 and then blown toward the guide surface 16 and flows along the surface of the guide surface 16. Since the guide surface 16 is an inclined surface, the flow direction of the gas can be changed, and the gas with changed flow direction can be discharged from the air outlet 13. In this example, the cross section of the outer wall 15 is a trapezoid.

[0096] The guide surface 16 may also be configured as a smooth curved surface or an cambered surface.

[0097] refer to Figure 3 , Figure 3 Schematic diagram of the internal structure of the heating component provided in some other embodiments of the present application.

[0098] The heating component further includes a first insulating sheet 31 and a second insulating sheet 32 ​​which are spaced apart and face each other along the third direction. The first insulating sheet 31 and the second insulating sheet 32 ​​have the following functions:

[0099] First, it acts as an electrical insulator, preventing current from flowing in unintended paths and avoiding electrical faults such as short circuits.

[0100] Second, it can effectively isolate the heating wire 2 from other components, reduce the heat transfer to other places that do not need to be heated, and improve the situation where surrounding electronic components and plastic materials are damaged by high temperature.

[0101] Specifically, the first insulating sheet 31 and the second insulating sheet 32 ​​are connected between the two support frames 14 .

[0102] As an optional solution, the heating wire 2 is wound around the outer circumference of the first insulating sheet 31 and the second insulating sheet 32 ​​.

[0103] Exemplarily, the heating wire 2 is wound around the outer periphery of the first insulating sheet 31, and the heating wire 2 is wound around the outer periphery of the second insulating sheet 32. Alternatively,

[0104] The heating wire 2 is integrally wound around the outer circumference of the first insulating sheet 31 and the second insulating sheet 32 ​​, and there is no heating wire 2 on the opposing surfaces of the first insulating sheet 31 and the second insulating sheet 32 ​​.

[0105] A support column 17 is also provided inside the heating component.

[0106] Specifically, the support column 17 is disposed between the first insulating sheet 31 and the second insulating sheet 32 ​​, and can enhance the strength between the first insulating sheet 31 and the second insulating sheet 32 ​​.

[0107] Electronic components are arranged on the first insulating sheet 31 and / or the second insulating sheet 32. The support column 17, the first insulating sheet 31 and / or the second insulating sheet 32, and the electronic components arranged on the first insulating sheet 31 and / or the second insulating sheet 32 ​​may share a fixing point, and the support column 17 may fix the electronic components on the first insulating sheet 31 and / or the second insulating sheet 32 ​​during assembly.

[0108] For reference Figure 4 and Figure 5 , Figure 4 This is a schematic diagram of the structure of the heating component provided by some other embodiments of the present application. Figure 5 for Figure 4 A schematic diagram of the structure in which the heating wire in the heating component is directly arranged between the first insulating sheet and the second insulating sheet.

[0109] As another optional solution, the heating wire 2 is directly disposed between the first insulating sheet 31 and the second insulating sheet 32 ​​.

[0110] refer to Figure 6 , Figure 6 A schematic diagram of a structure in which a gap is left between the first insulating sheet, the second insulating sheet and the outer wall of a heating component provided in some embodiments of the present application.

[0111] In the embodiment of the present application, a gap is left between the first insulating sheet 31 and / or the second insulating sheet 32 ​​and the adjacent outer wall 15 in the third direction. It should be noted that the outer wall 15 may be a top wall, a bottom wall or a side wall, and the first insulating sheet 31 and / or the second insulating sheet 32 ​​and the adjacent outer wall 15 may allow gas to pass therebetween.

[0112] As an optional technical solution, a first gap 21 is left between the first insulating sheet 31 and the outer wall 15 adjacent to it in the third direction.

[0113] As another optional technical solution, a second gap 22 is left between the second insulating sheet 32 ​​and the outer wall 15 adjacent to it in the third direction.

[0114] As another optional technical solution, a first gap 21 is left between the first insulating sheet 31 and the adjacent outer wall 15 in the third direction, and a second gap 22 is left between the second insulating sheet 32 ​​and the adjacent outer wall 15 in the third direction.

[0115] It should be understood that a third gap 23 may also be left between the first insulating sheet 31 and the second insulating sheet 32. The third gap 23 may also be used to accommodate and install electronic components.

[0116] In the above technical solution, by setting a first gap 21 between the first insulating sheet 31 and the outer wall 15 adjacent thereto in the third direction, a second gap 22 between the second insulating sheet 32 ​​and the outer wall 15 adjacent thereto, and a third gap 23 between the first insulating sheet 31 and the second insulating sheet 32, a winding space is reserved for the heating wire 2. Moreover, the first gap 21, the second gap 22, and the third gap 23 can heat the gas and allow the gas to pass through.

[0117] The heating component also includes a thermistor 4. The specific structure of the thermistor 4 is not limited in the embodiment of the present application, and the resistance value can decrease with the increase of temperature, such as a bead thermistor, a sheet thermistor, a rod thermistor, etc. In the embodiment of the present application, the specific structure of the thermistor 4 is a rod thermistor as an example for explanation.

[0118] Specifically, the thermistor 4 is disposed at a position close to the air outlet 13 , and the thermistor 4 is configured to detect the temperature of the gas at the air outlet 13 .

[0119] The number of thermistors 4 may be one or more.

[0120] A plurality of thermistors 4 are arranged at intervals along the first direction at positions close to the air outlet 13. In the embodiment of the present application, the plurality of thermistors 4 specifically refers to two or more thermistors 4, such as two thermistors 4, three thermistors 4, four thermistors 4, five thermistors 4, six thermistors 4, seven thermistors 4, eight thermistors 4, etc. In the embodiment of the present application, the number of thermistors 4 is four for illustration.

[0121] It should be understood that a plurality of thermistors 4 may also be arranged at intervals along the third direction at positions close to the air outlet 13 to detect the temperature of the gas at different positions away from the air outlet 13 .

[0122] The heating component also includes a control unit. The control unit is configured to obtain the value of the temperature detected by the thermistor 4. The control unit in the embodiment of the present application is a conventional control module that is equipped with a single-chip microcomputer or a chip with a software program embedded therein, and can realize the control circuit and the electronic device to perform logical judgment, calculation and execution of commands. The control unit obtains the value of the temperature detected by the thermistor 4 as an existing control logic.

[0123] Specifically, the control unit is electrically connected to the thermistor 4. There are multiple ways to electrically connect the control unit to the thermistor 4, for example: the control unit is electrically connected to the thermistor 4 through a wire, the control unit is electrically connected to the thermistor 4 through a signal, and the control unit is electrically connected to the thermistor 4 through a network.

[0130] refer to Figure 7 , Figure 7 A schematic diagram of the internal structure of the modeling equipment provided in some embodiments of the present application.

[0131] In the prior art, a plurality of heating elements are arranged in a metal plate of a styling device to heat the metal sheet, for example, a plurality of ceramic heating elements are arranged to heat the metal plate. However, when a plurality of heating elements are arranged to heat the metal sheet, the temperature of the local area of ​​the metal sheet close to the heating element is higher, and the temperature of the local area of ​​the metal sheet far from the heating element is lower. The temperature of the side of the metal sheet used to clamp the hair is uneven, which affects the effect of hair styling.

[0132] To this end, the present application also provides a modeling device. The modeling device includes one or more heating components in any of the above embodiments and two shell groups 8 that can be opened and closed. The shell group 8 is provided with a receiving groove 81, which can be used for assembly with the heating component.

[0133] For reference Figure 8 and Fig. 9 and Fig.10 , Figure 8 A cross-sectional view of a molding device provided for some embodiments of the present application, Fig. 9 A cross-sectional view of a molding device provided in some embodiments of the present application, Fig.10 A schematic diagram of the structure of a shell group in a molding device provided in some embodiments of the present application.

[0134] Specifically, at least one of the two shell groups 8 has an air duct 82 and an outlet structure 83. Among them, at least one of the two shell groups 8 has an air duct 82 and an outlet structure 83 in the embodiment of the present application specifically means that one of the two shell groups 8 has an air duct 82 and an outlet structure 83, and the other shell group 8 does not have an air duct 82 and an outlet structure 83, or both shell groups 8 have an air duct 82 and an outlet structure 83. The present application is described by taking one of the two shell groups 8 having an air duct 82 and an outlet structure 83 and the other shell group 8 not having an air duct 82 and an outlet structure 83 as an example.

[0135] One end of the air duct 82 is configured to be arc-shaped to facilitate smooth flow of gas.

[0136] The heating component is arranged between the air duct 82 and the outlet structure 83, the air inlet 12 of the heating component is connected to the air duct 82, and the air outlet 13 is connected to the outlet structure 83. The outlet structure 83 and the installation position of the heating component are combined to form a U-shaped structure, which is convenient for the gas to change the direction of the airflow along the U-shaped structure.

[0137] By arranging the heating component between the air duct 82 and the outlet structure 83, the heating component is kept away from the interior of the molding device, which can effectively reduce the heat generated by the heating component from diffusing into the interior of the molding device body, thereby increasing the service life of the molding device. At the same time, arranging the heating component in the outlet structure 83 can also reduce the size and volume of the molding device body, making it easier to store and use.

[0138] Specifically, the outlet structure 83 includes a flow channel 831. The flow channel 831 is used to provide a channel for the flowing fluid, and illustratively, to provide a channel for the flow of gas.

[0139] Specifically, the flow channel 831 is communicated with the air outlet 13 .

[0140] The outlet structure 83 further includes an opening 832. The opening 832 is connected to the flow channel 831, and the opening 832 is opened toward the second direction and extends along the first direction. The number of the openings 832 can be one or more.

[0141] As an optional technical solution, the number of the opening 832 is one, the opening 832 is opened toward the second direction, and the opening 832 extends along the first direction.

[0142] As another optional technical solution, there are multiple openings 832, the openings 832 are opened toward the second direction, the openings 832 extend along the first direction, and the multiple openings 832 are arranged at intervals along the first direction. In the embodiment of the present application, the multiple openings 832 specifically refer to two or more openings 832, such as: two openings 832, three openings 832, four openings 832, five openings 832, six openings 832, seven openings 832, eight openings 832, etc. In the embodiment of the present application, the number of openings 832 is four as an example for description.

[0143] After the heating component is assembled on the styling device, during the operation of the styling device, the air passes through the air duct 82, is heated by the heating component 2, and flows to the outlet structure 83, and flows out through the opening 832 of the outlet structure 83. Since the opening 832 extends along the first direction, the cross section of the airflow blown out from the opening 832 is long and strip-shaped, thereby improving the effect of styling the hair.

[0144] In the embodiment of the present application, the two shell groups 8 have two clamping surfaces 9 arranged opposite to each other. The specific shape of the clamping surface 9 is not limited in the present application, and it can be a long strip, such as a rectangle, an ellipse, etc. In the embodiment of the present application, the specific shape of the clamping surface 9 is a rectangle as an example for explanation.

[0145] Specifically, at least one clamping surface 9 is provided with a metal plate 91. Among them, at least one clamping surface 9 is provided with a metal plate 91 in the embodiment of the present application specifically means that the clamping surface 9 of one shell group 8 of the two shell groups 8 is provided with a metal plate 91, the clamping surface 9 of the other shell group 8 is not provided with a metal plate 91, or both clamping surfaces 9 of the two shell groups 8 are provided with metal plates 91.

[0146] As an optional solution, a metal plate 91 is provided on the clamping surface 9 of one shell group 8 among the two shell groups 8 , while a metal plate 91 is not provided on the clamping surface 9 of the other shell group 8 .

[0147] Specifically, the metal plate 91 is laid flat on the outside of the flow channel 831, and the heated gas flowing through the flow channel 831 can evenly heat the metal plate 91 laid flat on the outside of the flow channel 831, so that the hair can be better styling by using the styling equipment to clamp the hair.

[0148] As another optional solution, metal plates 91 are provided on both clamping surfaces 9 of the two shell groups 8 .

[0149] Specifically, the two metal plates 91 are provided with flow channels 831 on one side facing away from the shell groups 81 opposite to each other, and the heated gas flowing through the flow channels 831 contacts the metal plates 91, so that the metal plates 91 are evenly heated, and then the two metal plates 91 of the two oppositely arranged shell groups 8 are heated by the gas, so the temperature on the two metal plates 91 is relatively uniform. When the styling device is used to clamp hair, the hair is heated to achieve a better styling effect.

[0150] In the embodiment of the present application, the thickness of the metal plate 91 ranges from 0.2 mm to 0.4 mm. For example, the thickness of the metal plate 91 is 0.2 mm, 0.23 mm, 0.25 mm, 0.28 mm, 0.3 mm, 0.32 mm, 0.35 mm, 0.38 mm, and 0.4 mm. In the embodiment of the present application, the thickness of the metal plate 91 is 0.3 mm as an example for description.

[0151] By setting the thickness of the metal plate 91 to a range of 0.2 mm to 0.4 mm, the metal plate 91 can be quickly heated, the preheating time can be reduced, and energy can be saved.

[0152] In the embodiment of the present application, a motor 10 is further provided in the shell group 8 , and the function of the motor 10 is to provide flowing gas for the air duct 82 .

[0154] In the embodiment of the present application, ribs 84 are further provided between the air duct 82 and the outlet structure 83 , which can play a role in supporting the shell group 8 .

[0155] The ribs 84 are arranged between the air duct 82 and the outlet structure 83, and the surface of the ribs 84 facing the air duct 82 is arranged as an inclined surface or a smooth curved surface, which can also play a role in guiding and dispersing the airflow, making the airflow distribution more uniform.
