[0068] As part of the creative concept of the present disclosure, before describing the embodiments of the present disclosure, it is necessary to analyze the reasons why hair styling irons in related technologies are inconvenient to use with two hands and the users have inconsistent force when turning the knobs, and to obtain the technical solutions of the embodiments of the present disclosure through reasonable analysis.

[0069] In the related art, a hair styling iron combines the functions of multiple tools such as a hair dryer, a curling iron, and a comb, meeting the different usage needs of users, making hair styling irons widely used in the hairdressing industry. Generally, a hair styling iron includes a body, a knob, a handle, and a switching component. The body is provided with multiple air outlets (the air outlets may include centralized air outlets and decentralized air outlets). The knob and the handle are arranged at opposite ends of the body. The switching component is rotatably arranged inside the body. An air flow channel is provided inside the switching component. A connecting channel is provided on the wall surface of the switching component. The knob is connected to the switching component and can drive the switching component to rotate relative to the body to switch the air flow channel to different air outlets through the connecting channel. The airflow in the air flow channel can be directed to the corresponding air outlet, and the airflow can be blown out from different directions, thereby adapting to different blowing modes of the hair styling iron. Among them, the hair dryer's blowing modes include: 1) concentrated blowing mode, in which the airflow in the airflow channel flows into the centralized air outlet to achieve the function of concentrated air outlet; 2) surround blowing mode, in which the airflow in the airflow channel flows into multiple dispersed air outlets to achieve the function of dispersed air outlet in a specific area.

[0070] However, there are still some technical problems when adopting the structural design of the above-mentioned hair styling iron, as follows: 1) Users often need to use both hands to switch the blowing mode, which is inconvenient. 2) The knob is easily touched by mistake; for example: when the user is curling the hair, the hair needs to be wrapped around the hair styling iron. The user holds the handle with one hand and the position of the hair styling iron near the knob with the other hand, and turns the hair up with both hands to curl the hair. During the rotation, it is easy to touch the knob by mistake, causing the blowing mode to be switched, affecting the styling effect and user experience, and even burning the surrounding skin. 3) Different users have different forces when turning the knob; specifically, due to the different usage habits of each user, the rotational force applied when manually turning the knob is also different. Users with strong strength may turn the knob too far, and users with weak strength feel that the rotation resistance is large and the rotation is laborious, which reduces the user experience.

[0071] To this end, the present disclosure provides a hair styling device, the hair styling device comprising a housing, a handle, a first barrel, a second barrel, a motor and a button; wherein the handle is connected to one end of the housing; the first barrel is arranged inside the housing, and a plurality of air outlet channels are arranged between the first barrel and the housing, and a wind guide opening is arranged on the barrel wall of the first barrel; the second barrel is arranged inside the first barrel, and the first barrel and the second barrel can rotate relative to each other, and an air outlet opening is arranged on the barrel wall of the second barrel; one of the first barrel and the second barrel is fixedly connected with the handle, and the other is connected with the motor; the motor is configured to control the relative rotation of the first barrel and the second barrel to change the relative position between the air outlet opening and the wind guide opening, and can guide the airflow in the inner cavity of the second barrel to different air outlet channels through the air outlet opening and the wind guide opening; the button is arranged on the handle, and the button is configured to control the start and stop of the motor and the operation of the motor. Thus, the technical problems that the hair styling device in the prior art needs to be operated by the user with both hands, is inconvenient to use, and the user rotates the knob with different forces, resulting in poor experience, are solved.

[0072] The technical solutions of the embodiments of the present disclosure are described in detail below with reference to the drawings. The technical features involved in the different embodiments of the present disclosure described below can be combined with each other as long as they do not conflict with each other.

[0073] Reference is made to Figure 1 , Figure 2 and Figure 4 , Figure 1 Fig. 1 shows a structural schematic diagram of a hair styling device according to some embodiments of the present disclosure, Figure 2 Fig. 2 shows a cross-sectional view of a wind guide opening and an air outlet opening in a first state according to some embodiments of the present disclosure, Figure 4 Fig. 3 shows a schematic diagram of the internal structure of a hair styling device according to some embodiments of the present disclosure.

[0074] In some embodiments, a hair styling device is provided. The hair styling device comprises a housing 1, a handle 2, a first barrel 3, a second barrel 4, a motor 5 and a button 6.

[0075] In this embodiment, the specific structure of the housing 1 is not limited in this embodiment, and can be a structure capable of accommodating other components, such as a shell having an accommodation cavity inside.

[0076] The housing 1 can be provided with comb teeth, comb hairs, air outlet holes and concentrated air nozzles. When the airflow flows to the air outlet holes between the comb teeth, the hair can be heated. When the airflow flows to the air outlet holes between the comb hairs, the hair can be curled or the hair can be dried while being combed. When the airflow flows to the concentrated air nozzles, the hair dryer can be used for drying the hair.

[0077] In this embodiment, the handle 2 is used to provide a hand-held position for the user to conveniently operate and control the hairdresser. Specifically, the handle 2 is connected to one end of the housing 1. The interior of the handle 2 may also be provided with an air inlet channel, a fan unit, a heating component, etc. The fan unit can draw the airflow outside the handle 2 into the air inlet channel. The airflow inside the air inlet channel can also be heated by the heating component to form a hot air flow. Figure 3 , Figure 3 A schematic structural diagram of a first cylinder and a second cylinder provided according to some embodiments of the present disclosure is shown.

[0078] In this embodiment, the specific shape of the first barrel 3 is not limited, and any shape having a cavity inside can be used, such as a cylinder having a cavity inside, an elliptical cylinder having a cavity inside, a prism having a cavity inside, etc. In this embodiment, the specific shape of the first barrel 3 is a cylinder having a cavity inside as an example for description.

[0079] Specifically, the first cylinder 3 is arranged inside the housing 1, and a plurality of air outlet channels are arranged between the first cylinder 3 and the housing 1.

[0080] Furthermore, an air guide port 33 is provided on the wall of the first cylinder 3. The air guide port 33 serves to guide the direction of the air flow, for example, to guide the air flow to the air outlet channel.

[0081] In this embodiment, the specific shape of the second barrel 4 is not limited, and any shape having a cavity inside can be used, such as a cylinder having a cavity inside, an elliptical cylinder having a cavity inside, a prism having a cavity inside, etc. In this embodiment, the specific shape of the second barrel 4 is a cylinder having a cavity inside as an example for description.

[0082] Specifically, the second barrel 4 is disposed inside the first barrel 3, and the two are capable of relative rotation. In this embodiment, the relative rotation of the two specifically refers to the first barrel 3 rotating relative to the second barrel 4 around the axis of the first barrel 3, or the second barrel 4 rotating relative to the first barrel 3 around the axis of the second barrel 4. This embodiment is described using the rotation of the first barrel 3 relative to the second barrel 4 around the axis of the first barrel 3 as an example.

[0083] Furthermore, an air outlet 41 is provided on the wall of the second cylinder 4. The air outlet 41 serves to allow air to be discharged from the second cylinder 4. For example, air inside the second cylinder 4 enters the air guide port 33 through the air outlet 41.

[0084] In this embodiment, one of the first barrel 3 and the second barrel 4 is fixedly connected to the handle 2 , and the other is fixedly connected to the motor 5 .

[0085] As an optional technical solution, the first cylinder 3 is fixedly connected to the handle 2 , and the second cylinder 4 is fixedly connected to the motor 5 .

[0086] As another optional technical solution, the first cylinder 3 is fixedly connected to the motor 5 , and the second cylinder 4 is fixedly connected to the handle 2 .

[0087] In this embodiment, the specific type of the motor 5 is not limited, and any motor that can drive the first barrel 3 or the second barrel 4 to rotate can be used, such as an empty cup motor, a stepping motor, etc.

[0088] The motor 5 is configured to control the rotation of the first barrel 3 or the second barrel 4 connected thereto to change the relative position between the air outlet 41 and the air guide port 33, and to guide the airflow in the inner cavity of the second barrel 4 to different air outlet channels through the air outlet 41 and the air guide port 33, so that the hair dryer can switch between different working modes.

[0089] In this embodiment, the button 6 is configured to control the start and stop and operation of the motor 5. It should be noted that the operation of the motor 5 controlled by the button 6 in this embodiment includes but is not limited to the rotation direction and speed of the motor 5 controlled by the button 6.

[0090] Specifically, the button 6 is provided on the handle 2 .

[0091] In the above technical solution, the motor 5 can drive the first barrel 3 and the second barrel 4 to rotate relative to each other, changing the relative position of the air outlet 41 and the air guide 33, and switching the inner cavity of the second barrel 4 to connect with different air outlet channels. This can then guide the airflow within the second barrel 4 to different air outlet channels to adapt to different blowing modes of the hair dryer. The motor 5 is controlled by a button 6, which is located on the handle 2. The user controls the opening and closing of the motor 5 and the operation of the motor 5 by button 6, enabling single-handed operation to switch the hair dryer's blowing mode. At the same time, because the motor 5 replaces the knob in the prior art and is controlled by button 6, the problems of inconsistent knob force and accidental knob touching are avoided.

[0092] In some embodiments, the motor 5 is disposed at an end of the housing 1 away from the handle 2. Since the handle 2 is internally provided with components such as a circuit board and a motor for blowing, disposing the motor 5 at the end of the housing 1 away from the handle 2 is beneficial for optimizing the space layout.

[0093] In some embodiments, the motor 5 is in transmission connection with the first barrel 3 via its output shaft, and the second barrel 4 is connected to the handle 2. In this embodiment, transmission connection refers to the ability of two or more components to transmit force or power when assembled together. For example, the motor 5 is in transmission connection with the first barrel 3 via its output shaft, and the output shaft of the motor 5 can drive the first barrel 3 to rotate.

[0094] Because the second barrel 4 is disposed within the first barrel 3 and the two are able to rotate relative to each other, the airflow within the hair dryer first flows from the interior of the handle 2 into the interior of the second barrel 4, then flows through the air outlet 41 into the air guide 33 of the first barrel 3, and finally flows through the air guide 33 to different air outlet channels.

[0095] Therefore, setting the output shaft of the motor 5 in driving connection with the first cylinder 3 and the second cylinder 4 in fixed connection with the handle 2 is conducive to improving the airtightness of the connection between the second cylinder 4 and the handle 2. On the contrary, if the output shaft of the motor 5 is in driving connection with the second cylinder 4 and the first cylinder 3 is in fixed connection with the handle 2, then during the process of airflow from the interior of the handle 2 into the interior of the second cylinder 4, since the second cylinder 4 and the handle 2 also rotate relative to each other, the airtightness between the second cylinder 4 and the handle 2 is poor, which is prone to gas leakage.

[0096] In some embodiments, a connector 7 is provided between the output shaft of the motor 5 and the end of the first barrel 3 away from the handle 2. The connector 7 serves to provide a mechanical connection and facilitate assembly and disassembly of other components. For example, if two components cannot be directly assembled, the connector 7 can be connected to the two components at both ends to facilitate assembly.

[0097] In the above technical solution, a connector 7 is provided between the output shaft of the motor 5 and the end of the first barrel 3 away from the handle 2. This allows for direct replacement of worn connector 7, facilitating maintenance of the hair dryer and reducing maintenance costs. Furthermore, the provision of connector 7 facilitates assembly and disassembly between the output shaft of the motor 5 and the end of the first barrel 3 away from the handle 2.

[0098] In this embodiment, a first engaging portion is provided between the connector 7 and the output shaft. The first engaging portion is configured to restrict the circumferential positioning between the connector 7 and the output shaft. The specific structure of the first engaging portion is not limited in this embodiment; any structure capable of restricting the circumferential positioning between the connector 7 and the output shaft may be employed, such as a snap-fit ​​structure, a mortise and tenon structure, or a nested structure. This embodiment uses the nested structure of the first engaging portion as an example for illustration.

[0099] In this embodiment, a second engaging portion is provided between the connector 7 and the first cylindrical body 3. The second engaging portion is configured to restrict the circumferential positioning between the connector 7 and the first cylindrical body 3. The specific structure of the second engaging portion is not limited in this embodiment; any structure capable of restricting the circumferential positioning between the connector 7 and the first cylindrical body 3 may be employed, such as a snap-fit ​​structure, a mortise and tenon structure, or a nested structure. This embodiment uses the nested structure as an example for description.

[0100] For reference Figure 5 、 Figure 6 、 Figure 7 and Figure 8 , Figure 5 A schematic diagram of the structure of a cross protrusion provided according to some embodiments of the present disclosure is shown. Figure 6 A schematic diagram showing the structure of a first angle of a connector provided according to some embodiments of the present disclosure is shown. Figure 7 A schematic diagram showing a second angle structure of a connector provided according to some embodiments of the present disclosure is shown. Figure 8 A top view of an end portion of a first cylinder provided according to some embodiments of the present disclosure is shown.

[0101] In some embodiments, the first engaging portion and the second engaging portion have different structures.

[0102] Specifically, one of the first engaging portion and the second engaging portion is a matching structure of a cross protrusion 71 and a cross groove 72 , and the other is a matching structure of a star-shaped protrusion 73 and a star-shaped groove 74 .

[0103] When the first engaging portion is a matching structure of a cross protrusion 71 and a cross groove 72 , one of the cross protrusion 71 and the cross groove 72 is arranged at the end of the output shaft facing the connecting member 7 , and the other is arranged at the end of the connecting member 7 facing the output shaft.

[0104] When the second engaging portion is a matching structure of a star-shaped protrusion 73 and a star-shaped groove 74 , one of the star-shaped protrusion 73 and the star-shaped groove 74 is arranged at the end of the first cylinder 3 facing the connecting member 7 , and the other is arranged at the end of the connecting member 7 facing the first cylinder 3 .

[0105] It should be understood that, in addition to the matching structure of the cross protrusion 71 and the cross groove 72 and the matching structure of the star-shaped protrusion 73 and the star-shaped groove 74, the first engaging portion and the second engaging portion may also be matching structures of other shapes, such as: the matching structure of a quadrilateral protrusion and a quadrilateral groove, the matching structure of a pentagonal protrusion and a pentagonal groove, the matching structure of a hexagonal protrusion and a hexagonal groove, the matching structure of a heptagonal protrusion and a heptagonal groove, the matching structure of an octagonal protrusion and an octagonal groove, etc. As long as the structure can limit the circumferential positioning between the connecting member 7 and the output shaft, and the structure can limit the circumferential positioning between the connecting member 7 and the first cylinder 3.

[0106] In the above technical solution, by providing the first engaging portion and the second engaging portion with different structures, it is possible to avoid incorrect installation of the connecting member 7, the output shaft, and the first cylinder 3, thereby achieving a foolproofing effect. It should be noted that, in this embodiment, foolproofing specifically refers to a preventive and corrective behavioral restraint method, which uses a restrictive method to avoid errors, allowing users to directly and accurately complete correct operations without expending attention, experience, or professional knowledge.

Figure 9 , Figure 9 A cross-sectional view of the air guide and the air outlet provided in some embodiments of the present disclosure in the second state is shown.

[0108] In some embodiments, the air outlet channel includes a first air outlet channel 81 and a second air outlet channel 82 .

[0109] The air guide port 33 is provided with a first shielding portion 31 and a second shielding portion 32 on both sides of the circumference of the first cylinder 3. The first shielding portion 31 and the second shielding portion 32 may be shielding structures provided on the air guide port 33. The first shielding portion 31 and the second shielding portion 32 may also be part of the cylinder wall of the first cylinder 3.

[0110] Driven by the motor 5 , the first barrel 3 rotates relative to the second barrel 4 , and the air outlet 41 and the air guide port 33 have at least a first state and a second state.

[0111] In the first state, the first shielding portion 31 blocks the air outlet 41 and the first air outlet channel 81 , and the air guide port 33 communicates with the air outlet 41 and the second air outlet channel 82 .

[0112] Specifically, driven by the motor 5, the first barrel 3 rotates relative to the second barrel 4. As the first barrel 3 and the second barrel 4 rotate relative to each other, the first shielding portion 31 rotates to a position between the air outlet 41 and the first air outlet channel 81, thereby blocking the air outlet 41 and the first air outlet channel 81. Simultaneously, the second shielding portion 32 rotates from a position blocking the air outlet 41 and the second air outlet channel 82 to a position that releases the blockage between the air outlet 41 and the second air outlet channel 82. At this point, the air guide 33 connects the air outlet 41 and the second air outlet channel 82, and airflow within the hair dryer flows from the air outlet 41 through the air guide 33 into the second air outlet channel 82.

[0113] The second state is: the second shielding portion 32 blocks the air outlet 41 and the second air outlet channel 82 , and the air guide port 33 communicates with the air outlet 41 and the first air outlet channel 81 .

[0114] Specifically, under the drive of the motor 5, the first barrel 3 rotates relative to the second barrel 4, and the second blocking part 32 rotates to between the air outlet 41 and the second air outlet channel 82 with the relative rotation of the first barrel 3 and the second barrel 4, and then the second blocking part 32 blocks between the air outlet 41 and the second air outlet channel 82. At the same time, the first blocking part 31 rotates from the position between the air outlet 41 and the first air outlet channel 81 to the position of unblocking between the air outlet 41 and the first air outlet channel 81. At this time, the air guide 33 connects the air outlet 41 and the first air outlet channel 81, and the airflow in the hair styling device flows from the air outlet 41 into the first air outlet channel 81 through the air guide 33.

[0115] It should be noted that the first state and the second state are two different relative positions of the air guide 33 and the air outlet 41, which can make the airflow flow to different air outlet channels, and then correspond to two different working modes of the hair styling device, such as: the first state corresponds to the concentrated air outlet mode of the hair styling device, and the second state corresponds to the surrounding air outlet mode of the hair styling device.

[0116] It can be understood that different numbers of air outlets 41 and air guides 33 can be set according to needs. According to the number of air outlets 41 and air guides 33, in the first state, the first blocking part 31 and the second blocking part 32 can be simultaneously blocked between the air outlet 41 and the first air outlet channel 81.

[0117] In some embodiments, a first limiting part 34 is arranged on the inner wall of the first barrel 3.

[0118] A second limiting part 42 is arranged on the outer wall of the second barrel 4.

[0119] For example, one of the first limiting part 34 and the second limiting part 42 is a limiting protrusion, and the other is a limiting groove, and the limiting protrusion can extend into the limiting groove.

[0120] In the circumferential direction of the first barrel 3, the limiting protrusion can only rotate in the inside of the limiting groove to limit the rotation angle range of the first barrel 3 relative to the second barrel 4.

[0121] In the above technical solution, through the cooperation of the first limiting part 34 and the second limiting part 42, the angle range of the relative rotation of the first barrel 3 and the second barrel 4 can be limited. At the same time, it can also play the function of installing and positioning the first barrel 3 and the second barrel 4.

[0122] In some embodiments, the limiting protrusion is a rib extending in the axial direction of the second barrel 4.

[0123] Specifically, the number of the ribs is multiple. In the embodiment, the number of the ribs is two, three, four, five, etc.

[0124] Further, the adjacent two ribs and the inner wall of the first barrel 3 and the outer wall of the second barrel 4 form a wire passing channel 43, which is configured to pass the wire connected between the motor 5 and the button 6.

[0125] Since the motor 5 is fixedly connected with the shell 1 in the embodiment, the motor 5 is drivingly connected with the first barrel 3 through the output shaft thereof, and the second barrel 4 is fixedly connected with the handle 2. Therefore, the ribs arranged on the second barrel 4 are stationary relative to the handle 2. Further, the wire in the wire passing channel 43 will not rotate and wind with the rotation of the first barrel 3, thereby causing breakage.

[0126] The limiting groove has a first side 341 and a second side 342 on two sides in the circumferential direction of the first barrel 3.

[0127] When the limiting protrusion abuts against the first side 341, the air outlet 41 and the air guide opening 33 are in the first state.

[0128] When the limiting protrusion abuts against the second side 342, the air outlet 41 and the air guide opening 33 are in the second state.

[0129] By arranging that the air outlet 41 and the air guide opening 33 are in the first state when the limiting protrusion abuts against the first side 341, and the air outlet 41 and the air guide opening 33 are in the second state when the limiting protrusion abuts against the second side 342, the angle stroke of the relative rotation between the first barrel 3 and the second barrel 4 is limited.

[0130] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present disclosure, but not to limit it; although the present disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present disclosure, and they should be covered in the scope of the claims and the specification of the present disclosure.
