[0056] 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 problem of poor styling effect after hair shaping in the related art, and obtain the technical solution of the embodiments of the present application through reasonable analysis.

[0057] In the related art, the development of hairdressing tools has experienced an evolution from primitive tools to metal tools, electric tools, and then to modern and environmentally friendly tools. With the advancement and innovation of science and technology, especially the invention of generators, electric hairdressing tools have begun to rise. These electric tools make trimming and styling hair more convenient and quick. Tools such as hair dryers, curling irons, and hair straighteners have become essential hairdressing tools for people. They can not only better meet people's needs for hair styling, but also be safer and more convenient. Hair straighteners are also called hair straighteners or electric plywood or plywood. The core technology of hair straighteners is to heat the heating element through electric current, and then conduct the heat to the aluminum plate or ceramic plate to make it heat up. When the hair passes through these heated plates, it will be heated and softened, and then the effect of the hairstyle will be fixed by cooling. At present, hair straighteners can both straighten and curl; based on the principle, the heating stage of the hair straightener is to shape the hair, and the waiting stage for cooling is to shape the hair. However, during the waiting time for shaping, the hair is always easy to be disturbed again, so there is an urgent need for a hair straightener that can quickly cool and shape the shaped hair.

[0058] To this end, the present application provides a hairstyling iron, which includes a fluid channel, a fluid inlet and a fluid outlet, wherein the fluid channel is arranged inside the arm, and the fluid outlet is arranged on one side of the heating unit; the above structure enables the fluid provided by the fluid source to enter the fluid channel through the fluid inlet and be discharged from the fluid outlet, so that the fluid can cool the hair heated and shaped by the heating unit in time, shortening the waiting time for styling, thereby solving the technical problem of poor styling effect after hair styling in the prior art.

[0059] 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.

[0060] For reference Figures 1 to 4 and Fig.10 , Figure 1 A schematic diagram of the structure of a hair styling device provided in some embodiments of the present application with two arms in an open state; Figure 2 A schematic diagram of the structure of a hair styling device provided in some embodiments of the present application with two arms in a closed state; Figure 3 A schematic diagram of a three-dimensional structure of an arm provided in some embodiments of the present application, wherein a fluid channel 14 is provided inside the arm; Figure 4 A schematic diagram of the internal structure of an arm provided in some embodiments of the present application, wherein a fluid channel 14 is provided inside the arm; Fig.10 A schematic diagram of the internal structure of a hair dryer provided in some embodiments of the present application.

[0061] In an embodiment of the present application, a hair styler is provided, such as Figure 1 and Figure 2 As shown, the hairstyling iron comprises two arms and a heating unit.

[0062] In this embodiment, the two arms can open and close to each other; illustratively, as Figure 1 and Figure 2 As shown, a specific structure in which the two arms can be opened and closed may be: one end of the two arms is hinged through the axis 3, and the other end of the two arms can rotate around the axis 3 to achieve the opening and closing action between the two arms.

[0063] In this embodiment, the heating unit is mainly used to heat the hair to shape the hair. Exemplarily, a specific structure of the heating unit can be: the heating unit includes a heating element and a heating plate, the heating element can be heated by electric current, optionally, the heating element can be a metal ceramics heater (MCH), a positive temperature coefficient thermistor heater (PTC) or a heating wire; the heating plate is wrapped around the outside of the heating element, the heat of the heating element can be conducted to the heating plate, the heating plate can clamp the hair and heat the hair for shaping, if the shaping is straight hair, the surface of the heating plate clamping the hair can be designed as a plane, if the shaping is curly hair, the surface of the heating plate clamping the hair can be designed with corresponding concave and convex shapes, preferably, the heating plate can be an aluminum plate or a ceramic plate.

[0064] Furthermore, the two arms have clamping surfaces arranged opposite to each other, and the two clamping surfaces can be designed near the ends where the two arms can be opened and closed. The heating unit has a connecting surface and a heating surface arranged opposite to each other, wherein the connecting surface is used to connect with the clamping surface, and the heating surface is used to directly contact the hair and heat and shape the hair. The number of heating units can be one or two or more; when only one heating unit is designed, the connection surface of the heating unit is connected to one clamping surface, and the heating surface of the heating unit is arranged toward the other clamping surface, the hair can be clamped between the heating surface and the other clamping surface, and the hair can be heated and shaped on one side through the heating surface; when two heating units are designed, the connection surfaces of the two heating units are connected to the two clamping surfaces one by one, and the heating surfaces of the two heating units are arranged opposite to each other, the hair can be clamped between the two heating surfaces, and the hair can be heated and shaped on both sides through the heating surface; when more than two heating units are designed, these heating units can be reasonably distributed on the two clamping surfaces, and the heating surface of each heating unit has a corresponding heating surface or clamping surface, so as to achieve heating and shaping of the hair.

[0065] In this embodiment, if Figure 4As shown, at least one of the two arms is provided with a fluid channel 14, and the arm is provided with a fluid inlet 15 and a fluid outlet 16 connected to the fluid channel 14. It can also be understood that both arms are provided with fluid channels 14, and each arm is provided with a fluid inlet 15 and a fluid outlet 16 connected to the corresponding fluid channel 14; or, only one arm is provided with a fluid channel 14, and the arm is provided with a fluid inlet 15 and a fluid outlet 16 connected to the fluid channel 14.

[0066] Furthermore, if Fig.10 As shown, the fluid inlet 15 is connected to the fluid source 61. The fluid source 61 may be a fan, a hair dryer, or an air compressor, etc. The fluid source 61 may be installed inside the main structure 6 (host), and then the main structure 6 is connected to the corresponding arm, and a communication channel is established between the fluid source 61 and the fluid inlet 15, so that the fluid (such as air) provided by the fluid source 61 is transported to the fluid inlet 15, and then enters the fluid channel 14 through the fluid inlet 15, and is discharged from the fluid outlet 16.

[0067] Furthermore, if Figure 3 As shown, the fluid outlet 16 is arranged on one side of the heating unit along the first direction X so that the fluid discharged through the fluid outlet 16 can cool the heated hair; wherein the first direction X is the moving direction of the hair heated by the heating unit moving out of the heating unit.

[0068] In this embodiment, by setting a fluid channel 14 inside the arm, the fluid provided by the fluid source 61 can enter the fluid channel 14 through the fluid inlet 15 and be discharged from the fluid outlet 16; and because the fluid outlet 16 is set on one side of the heating unit, the discharged fluid can timely cool the hair heated and shaped by the heating unit, thereby shortening the waiting time for styling and improving the styling effect of the hair.

[0069] For reference Figures 4 to 6 , Figure 4 A schematic diagram of the internal structure of an arm provided in some embodiments of the present application, wherein a fluid channel 14 is provided inside the arm; Figure 5 A schematic structural diagram of a channel cross section of a fluid channel 14 close to a fluid inlet 15 provided in some embodiments of the present application; Figure 6 A schematic structural diagram of a channel cross section of a fluid channel 14 away from a fluid inlet 15 provided in some embodiments of the present application.

[0070] In some embodiments, Figures 4 to 6As shown, the cross-sectional area of ​​the fluid channel 14 gradually decreases from the end close to the fluid inlet 15 to the end far from the fluid inlet 15. That is, the space of the fluid channel 14 tends to narrow, and the farther away from the fluid inlet 15, the narrower the space.

[0071] This embodiment adopts the structural design of the fluid channel 14. After the fluid provided by the fluid source 61 enters the fluid inlet 15, the fluid will be further accelerated as the space of the fluid channel 14 gradually narrows, and the fluid will be discharged from the fluid outlet 16 at a high speed to speed up the cooling of the hair, which is beneficial to shorten the hair styling time.

[0072] In some embodiments, Figures 4 to 6 As shown, a guide surface 141 for guiding the fluid to flow in the fluid channel 14 is provided inside the fluid channel 14 , and the guide surface 141 is a smooth curved surface.

[0073] It should be noted that, considering the overall layout of the hairdresser, the fluid channel 14 may be offset relative to the axis of the fluid source 61 providing the fluid, and the inner cavity of the fluid channel 14 may also have corners in order to avoid other components of the hairdresser. Based on this situation, a guide surface 141 is provided inside the fluid channel 14 (especially at the corners and the fluid inlet 15). The smooth curved guide surface 141 can guide the fluid to flow smoothly in the fluid channel 14, and the flow of the fluid in the fluid channel 14 will not be hindered by corners or protrusions.

[0074] In this embodiment, by providing a guide surface 141 in the fluid channel 14 , the influence of the internal structure of the fluid channel 14 on the fluid can be reduced, and the fluid can flow more smoothly in the fluid channel 14 .

[0075] For reference Figure 3 and Figure 7 , Figure 3 This is a schematic diagram of a three-dimensional structure of an arm provided in some embodiments of the present application, and a fluid channel 14 is provided inside the arm. Figure 3 The positional relationship between the fluid outlet 16 and the heating unit and the arrangement of the multiple fluid outlets 16 are shown; Figure 7 A schematic diagram of the internal structure of a hair dryer provided in some embodiments of the present application after the front end is cut off. Figure 7 The orientation of the fluid outlet 16 and the structure of the boss 17 are shown.

[0076] In some embodiments, Figure 7As shown, the fluid outlet 16 is arranged toward the side away from the heating unit; specifically, the fluid outlet 16 has two ports, which can be set as a first port and a second port, and the first port is communicated with the fluid channel 14, and the second port is communicated with the external space between the two arms. Since the fluid outlet 16 is arranged on the side of the heating unit along the first direction X, the fluid outlet 16 is arranged toward the side away from the heating unit, which means that the second port is arranged away from the heating unit relative to the first port, that is, the direction of the fluid outlet 16 is offset relative to the first direction X, and there is an angle between the two, wherein the direction of the fluid outlet 16 refers to the direction from the first port to the second port.

[0077] Further, the angle α between the direction of the fluid outlet 16 and the first direction X is in the range of 30°≤α≤40°. Optionally, the angle α may be, but is not limited to, 30°, 32°, 35°, 38°, or 40°.

[0078] In this embodiment, an inclined fluid outlet 16 is provided, that is, the direction of the fluid outlet 16 has an angle with the first direction X, so that the fluid discharged through the fluid outlet 16 will not be blown directly toward the hair, but will be blown toward the hair obliquely along the first direction X (that is, the moving direction of the hair heated by the heating unit moving out of the heating unit). The fluid can be blown toward the hair in a larger area, which is beneficial to improving the cooling efficiency of the hair; moreover, compared with the fluid blowing directly toward the hair, the fluid blowing toward the hair obliquely along the first direction X is less likely to disturb the shaped hair.

[0079] In some embodiments, Figure 3 As shown, there are multiple fluid outlets 16 , and the multiple fluid outlets 16 are arranged along the second direction Z; wherein the second direction Z is perpendicular to the first direction X.

[0080] It should be noted that when styling hair, a piece of hair is clamped and heated by the heating unit. Generally, the size of the heated hair in the second direction Z (the width of the hair) is close to the size of the heating unit in the second direction Z, so that the hair can be effectively heated. Accordingly, in order to ensure that the heated and shaped hair can be quickly cooled, a plurality of fluid outlets 16 can be provided in the second direction Z; optionally, the plurality of fluid outlets 16 are provided on one side of the heating unit along the first direction X, and are spaced from one end to the other end of the heating unit along the second direction Z.

[0081] Furthermore, the fluid channel 14 is extended along the second direction Z, and the plurality of fluid outlets 16 are distributed along the extension direction of the fluid channel 14. Considering that the space of the fluid channel 14 tends to narrow, and the space is narrower the farther away from the fluid inlet 15, the fluid flow rate discharged from each fluid outlet 16 can be made close to the same, ensuring that the fluid discharged from each fluid outlet 16 is more uniform, so that the hair can be cooled more evenly, thereby improving the cooling and shaping effect.

[0082] In this embodiment, by providing a plurality of fluid outlets 16, hair of a certain width can be cooled simultaneously, thereby improving the cooling and styling effect on the hair; in addition, the design of combining the structure of the plurality of fluid outlets 16 with the structure of the fluid channel 14 with a narrowing space trend can make the fluid discharged from each fluid outlet 16 more uniform, so that the hair can be cooled more uniformly, which can further improve the cooling and styling effect on the hair.

[0083] In some embodiments, Figure 7 As shown, a boss 17 is arranged on the clamping surface, and the boss 17 is arranged on one side of the heating unit along the first direction X to support the hair after being removed from the heating unit.

[0084] It should be noted that after the heating unit is assembled to the clamping surface, the heating surface of the heating unit in contact with the hair generally protrudes from the clamping surface, so that there is a height difference between the clamping surface and the heating surface of the heating unit. The hair heated and shaped by the heating unit will fall onto the clamping surface after being moved away from the heating surface along the first direction X. The shaped hair is easy to bend and disturbed due to the height difference, so a boss 17 is provided on the clamping surface, and the boss 17 is used to support the shaped hair and make the shaped hair as parallel as possible to the hair on the heating surface, which is conducive to maintaining the shaping effect of the hair.

[0085] Furthermore, the protruding height of the boss 17 gradually increases along the first direction X, so that the side of the boss 17 close to the hair is an inclined surface; wherein the maximum protruding height of the boss 17 does not exceed the height of the hair clamped by the heating unit. With the above structural design, an inclined surface is designed on the boss 17, wherein the high point of the inclined surface can be used to support the hair after being removed from the heating unit, and a space is formed between the low point of the inclined surface and the corresponding hair, and the space is conducive to natural wind cooling the corresponding hair.

[0086] Further, the value range of the angle β between the inclined surface and the first direction X is: 3°≤β≤4°. Optionally, the angle β may be, but is not limited to, 3°, 3.2°, 3.5°, 3.8°, or 4°.

[0087] Furthermore, the fluid outlet 16 penetrates the middle area of ​​the boss 17. With the above structural design, the fluid outlet 16 is designed in the middle area of ​​the boss 17, and the fluid discharged through the fluid outlet 16 can cool the hair it faces, and the fluid partially blocked by the hair and flowing back can enter the space formed between the depression of the inclined surface and the corresponding hair to cool the hair corresponding to the space. This structural design can improve the cooling and shaping efficiency of the hair.

[0088] In this embodiment, by providing a boss 17 with an inclined surface, the high point on the inclined surface of the boss 17 can be used to support the shaped hair to avoid bending and disturbance of the shaped hair. The low-lying area on the inclined surface of the boss 17 and the space surrounded by the corresponding hair and the heating unit can also be used to cool the hair, wherein the space allows the corresponding hair to fully contact with the air or natural wind, which is beneficial to the cooling of the corresponding hair; in addition, the space can also cooperate with the fluid outlet 16 structure provided on the boss 17, so that part of the fluid blocked by the hair and refluxed can enter the space to cool the corresponding hair, which can improve the cooling and shaping efficiency of the hair.

[0089] For reference Figures 8 to 10 , Figure 8 An exploded view of two arms in a hair styling iron provided in some embodiments of the present application, Figure 8 The specific structure of the fluid channel 14 is shown; Fig. 9 A schematic diagram of the three-dimensional structure of a hair dryer provided in some embodiments of the present application; Fig.10 A schematic diagram of the internal structure of a hair dryer provided in some embodiments of the present application, Fig.10 The structural relationship between the fluid source 61 and the fluid channel 14 is shown.

[0090] In some embodiments, Figures 8 to 10 As shown, at least one arm includes a heat insulating plate 13 and a first inner shell 12 equipped with a heating unit; a fluid channel 14 is formed by the heat insulating plate 13 and the first inner shell 12 .

[0091] Exemplarily, a specific structure of a hair dryer may be: the hair dryer includes two arms, two heating units and a main structure 6, the two arms are respectively a first arm 1 and a second arm 2, the two heating units are respectively a first heating unit 4 and a second heating unit 5, the first arm 1 includes a first outer shell 11, a first inner shell 12 and a heat insulation board 13, and the second arm 2 includes a second outer shell 21 and a second inner shell 22.

[0092] The first inner shell 12 and the heat insulation board 13 are assembled and installed on the first outer shell 11 to form a first arm 1. A fluid channel 14 is formed between the first inner shell 12 and the heat insulation board 13. Specifically, a fluid inlet 15 is arranged on the heat insulation board 13, and a fluid outlet 16 is arranged on the first inner shell 12. The first heating unit 4 is installed on the first inner shell 12 and is arranged adjacent to the fluid outlet 16. The second outer shell 21 and the second inner shell 22 are assembled to form a second arm 2. The second heating unit 5 is installed on the second inner shell 22. One end of the first arm 1 is hinged to the second arm 2 through the shaft 3, and the other end of the first arm 1 is hinged to the second arm 2 through the shaft 3. The ends can be opened and closed. After the first arm 1 and the second arm 2 are assembled, the two heating units can be relatively arranged at the opening and closing ends of the two arms; a fluid source 61 and a connecting channel are arranged inside the main structure 6. The main structure 6 is connected to the first arm 1. After the two are assembled, the fluid source 61 and the fluid inlet 15 can be connected by the connecting channel, and the outlet size of the connecting channel is larger than the size of the fluid inlet 15. The fluid provided by the fluid source 61 is transported to the fluid inlet 15 through the connecting channel, and then enters the fluid channel 14, and finally discharged from the fluid outlet 16, and can be blown to the hair after heating and shaping, so as to improve the cooling and shaping effect of the hair.

[0093] This embodiment has a reasonable layout, that is, the fluid channel 14 is surrounded by the heat insulation board 13 and the first inner shell 12, and can be modified on the basis of the original product with minor changes, which can effectively reduce the production cost.
