It should be understood that the thickness, length and other dimensions of various components in the embodiments of the present disclosure shown in the drawings, as well as the overall thickness, length and other dimensions of the integrated device are only exemplary descriptions and should not constitute any limitation to the present disclosure.

[0030] 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 the hair dryer in the related art is inconvenient to use with two hands and the user has inconsistent force when turning the knob, and obtain the technical solution of the embodiments of the present disclosure through reasonable analysis.

[0031] In the related art, a hair styling iron combines the functions of a variety of tools such as a hair dryer, a curling iron, and a comb to meet the different usage needs of users, making the hair styling iron widely used in the hairdressing industry. Generally, the hair styling iron includes a body, a knob, a handle, and a switching component. The body is provided with a plurality of 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 arranged inside the switching component. A connecting channel is arranged on the wall of the switching component. The knob is connected to the switching component and can drive the switching component to rotate relative to the body, so as to realize the switching connection between the air flow channel and different air outlets through the connecting channel, and the air flow in the air flow channel can be directed to the corresponding air outlet, so that the air flow can be blown out from different directions, thereby adapting to different blowing modes of the hair styling iron. Among them, the blowing modes of the hair dryer include: 1) concentrated blowing mode, which means that the airflow in the airflow channel flows into the centralized air outlet to realize the function of concentrated air outlet; 2) surround blowing mode, which means that the airflow in the airflow channel flows into multiple decentralized air outlets to realize the function of decentralized air outlet in a specific area.

[0032] However, there are still some technical problems when adopting the structural design of the above-mentioned hair dryer, as follows: 1) Users often need to use both hands to switch the blowing mode, which is inconvenient. 2) The knob is easy to be touched by mistake; for example: when the user is curling the hair, the hair needs to be wrapped around the hair dryer. The user holds the handle with one hand and the position of the hair dryer near the knob with the other hand. Both hands turn up 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 scalding the surrounding skin. 3) Different users have different strengths when turning the knob; specifically, due to the different usage habits of each user, the rotational force applied when manually rotating the knob is also different. Users with strong strength may cause the knob to rotate too much, and users with weak strength feel that the rotational resistance is large and the rotation is laborious, which reduces the experience.

[0033] To this end, the present disclosure provides a hairdresser, which includes 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, a plurality of air outlet channels are arranged between the first barrel and the second barrel, and an air guide port is provided on the barrel wall of the first barrel; the second barrel is arranged inside the first barrel, the first barrel and the second barrel can rotate relative to each other, and an air outlet is provided on the barrel wall of the second barrel; one of the first barrel and the second barrel is fixedly connected to the handle, and the other is connected to 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 and the air guide port, and can guide the airflow in the inner cavity of the second barrel to different air outlet channels via the air outlet and the air guide port; the button is arranged on the handle, and the button is configured to control the opening and closing and operation of the motor. Thus, the technical problems that the hairdresser in the prior art requires the user to operate with both hands, which is inconvenient to use, and the user's rotation knob force is not uniform, resulting in a poor experience.

[0034] The technical solutions of the embodiments of the present disclosure are described in detail below in conjunction with the accompanying drawings. The technical features involved in the different embodiments of the present disclosure described below can be combined with each other as long as there is no conflict between them.

[0035] For reference Figure 1 , Figure 2 and Figure 4 , Figure 1 shows a schematic structural diagram of a hair dryer provided according to some embodiments of the present disclosure, Figure 2 shows a cross-sectional view of an air guide port and an air outlet in a first state according to some embodiments of the present disclosure, Figure 4 A schematic diagram of the internal structure of a hair dryer provided according to some embodiments of the present disclosure is shown.

[0036] In some embodiments, a hairstyling iron is provided, which comprises a housing 1 , a handle 2 , a first barrel 3 , a second barrel 4 , a motor 5 and a button 6 .

[0037] In this embodiment, the specific structure of the housing 1 is not limited in this embodiment, and any structure that can accommodate other components may be used, such as a housing with an accommodating cavity inside.

[0038] The housing 1 may be provided with comb teeth, combing hair, air outlet holes, and a concentrated air nozzle. When the air flows to the air outlet holes between the comb teeth, the hair may be heated. When the air flows to the air outlet holes between the combing hair, the hair may be curled or dried while combing the hair. When the air flows to the concentrated air nozzle, the hair may be used as a hair dryer to dry the hair.

[0039] In this embodiment, the handle 2 is used to provide a position for the user to hold the hair dryer, so that the user can conveniently operate and control the hair dryer. Specifically, the handle 2 is connected to one end of the housing 1. 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 airflow.

[0040] refer to 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.

[0041] 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.

[0042] Specifically, the first cylinder 3 is disposed inside the housing 1 , and a plurality of air outlet channels are disposed between the first cylinder 3 and the housing 1 .

[0043] 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 airflow, for example, to guide the airflow to the air outlet channel.

[0044] 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.

[0045] Specifically, the second barrel 4 is disposed inside the first barrel 3, and the two can rotate relative to each other. The two can rotate relative to each other in this embodiment specifically means that the first barrel 3 rotates relative to the second barrel 4 around the axis of the first barrel 3 or the second barrel 4 rotates relative to the first barrel 3 around the axis of the second barrel 4. In this embodiment, the first barrel 3 rotates relative to the second barrel 4 around the axis of the first barrel 3 as an example for explanation.

[0046] Furthermore, an air outlet 41 is provided on the wall of the second cylinder 4. The function of the air outlet 41 is to allow airflow to be discharged from the second cylinder 4. For example, the airflow inside the second cylinder 4 enters the air guide port 33 through the air outlet 41.

[0047] 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 .

[0048] 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 .

[0049] 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 .

[0050] In this embodiment, there is no limitation on the specific type of the motor 5 , and the motor 5 may be any motor capable of driving the first cylinder 3 or the second cylinder 4 to rotate, such as an empty cup motor, a stepping motor, etc.

[0051] 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 can guide the airflow in the inner cavity of the second barrel 4 to different air outlet channels via the air outlet 41 and the air guide port 33, so as to enable the hair dryer to switch between different working modes.

[0052] 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 button 6 controls the operation of the motor 5 in this embodiment, including but not limited to the button 6 controlling the rotation direction and speed of the motor 5.

[0053] Specifically, the button 6 is arranged on the handle 2 .

[0054] 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, change the relative position of the air outlet 41 and the air guide port 33, and realize the switching connection between the inner cavity of the second barrel 4 and different air outlet channels, thereby guiding the airflow in the second barrel 4 to flow to different air outlet channels to adapt to different blowing modes of the hair dryer. The motor 5 is controlled by the button 6, and the button 6 is set on the handle 2. The user controls the opening and closing and operation of the motor 5 by the button 6, and can realize one-handed operation to switch the blowing mode of the hair dryer. At the same time, since the motor 5 replaces the knob in the prior art, and the motor 5 is controlled by the button 6, the problem of inconsistent knob force and accidental knob touching is avoided.

[0055] 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 provided with components such as a circuit board and a motor for blowing, disposing the motor 5 at an end of the housing 1 away from the handle 2 is conducive to optimizing the space layout.

[0056] In some embodiments, the motor 5 is transmission-connected to the first barrel 3 through its output shaft, and the second barrel 4 is connected to the handle 2. In this embodiment, transmission connection means that after two or more parts are assembled together, force or power can be transmitted. For example, the motor 5 is transmission-connected to the first barrel 3 through its output shaft, and the output shaft of the motor 5 can drive the first barrel 3 to rotate.

[0057] Since the second barrel 4 is disposed inside the first barrel 3 and the two can rotate relative to each other, the airflow inside the hair dryer first flows from the inside of the handle 2 into the inside of the second barrel 4, then flows into the air guide port 33 of the first barrel 3 through the air outlet 41, and finally flows to different air outlet channels through the air guide port 33.

[0058] Therefore, setting the output shaft of the motor 5 to be transmission-connected with the first cylinder 3 and the second cylinder 4 to be fixedly connected with the handle 2 is conducive to improving the airtightness of the connection position between the second cylinder 4 and the handle 2. On the contrary, if the output shaft of the motor 5 is transmission-connected with the second cylinder 4 and the first cylinder 3 is fixedly connected with the handle 2, then in the process of the airflow flowing from the inside of the handle 2 into the inside of the second cylinder 4, since the second cylinder 4 and the handle 2 are also relatively rotated, the airtightness between the second cylinder 4 and the handle 2 is poor, which is easy to cause gas leakage.

[0059] In some embodiments, a connector 7 is provided between the output shaft of the motor 5 and the end of the first cylinder 3 away from the handle 2. The connector 7 is used for mechanical connection and to facilitate assembly and disassembly of other components. For example, if two components cannot be directly assembled, the two ends of the connector 7 are connected to the two components respectively, so that the two components can be assembled.

[0060] 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, and the worn connector 7 can be directly replaced, which is convenient for the maintenance of the hair dryer and reduces the maintenance cost. At the same time, the provision of the connector 7 also facilitates the assembly and disassembly between the output shaft of the motor 5 and the end of the first barrel 3 away from the handle 2.

[0061] In this embodiment, a first engaging portion is provided between the connecting member 7 and the output shaft. The first engaging portion is configured to limit the circumferential positioning between the connecting member 7 and the output shaft. The specific structure of the first engaging portion is not limited in this embodiment, and any structure that can limit the circumferential positioning between the connecting member 7 and the output shaft can be used, such as a snap-fit ​​structure, a mortise and tenon structure, a nested structure, etc. In this embodiment, the specific structure of the first engaging portion is a nested structure as an example for description.

[0062] In this embodiment, a second engaging portion is provided between the connecting member 7 and the first cylinder 3. The second engaging portion is configured to limit the circumferential positioning between the connecting member 7 and the first cylinder 3. The specific structure of the second engaging portion is not limited in this embodiment, and it can be a structure capable of limiting the circumferential positioning between the connecting member 7 and the first cylinder 3, such as a snap-fit ​​structure, a mortise and tenon structure, a nested structure, etc. In this embodiment, the specific structure of the second engaging portion is a nested structure as an example for description.

[0063] For reference Figure 5 , Figure 6 , Figure 7 and Figure 8 , Figure 5 shows a schematic diagram of the structure of a cross protrusion provided according to some embodiments of the present disclosure, Figure 6 shows a schematic diagram of the structure of a connector at a first angle according to some embodiments of the present disclosure, Figure 7 shows a schematic diagram of the structure of a second angle of a connector provided according to some embodiments of the present disclosure, Figure 8 A top view of an end portion of a first cylinder provided according to some embodiments of the present disclosure is shown.

[0064] In some embodiments, the first engaging portion and the second engaging portion have different structures.

[0065] 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 .

[0066] 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.

[0067] 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 .

[0068] 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 can 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 it is a structure that can limit the circumferential positioning between the connecting member 7 and the output shaft, and a structure that can limit the circumferential positioning between the connecting member 7 and the first cylinder 3.

[0069] In the above technical solution, by setting the first engaging part and the second engaging part to different structures, it is possible to avoid installation errors of the connecting member 7, the output shaft, and the first cylinder 3, thereby achieving a foolproof effect. It should be noted that foolproofing in this embodiment specifically refers to a preventive and corrective behavioral restraint method, which uses a restriction method to avoid errors, so that the user can directly and accurately complete the correct operation without paying attention, experience, or professional knowledge.

[0070] refer to Figure 2 , Figure 2 A cross-sectional view of the air guide port and the air outlet provided in some embodiments of the present disclosure in a first state is shown. Fig. 9 , Fig. 9 A cross-sectional view showing the air guide port and the air outlet in a second state according to some embodiments of the present disclosure is shown.

[0071] In some embodiments, the air outlet channel includes a first air outlet channel 81 and a second air outlet channel 82 .

[0072] 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 a part of the cylinder wall of the first cylinder 3.

[0073] Driven by the motor 5 , the first cylinder 3 rotates relative to the second cylinder 4 , and the air outlet 41 and the air guide port 33 have at least a first state and a second state.

[0074] The first state is that 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 .

[0075] Specifically, driven by the motor 5, the first barrel 3 rotates relative to the second barrel 4, and the first shielding portion 31 rotates to between the air outlet 41 and the first air outlet channel 81 as the first barrel 3 and the second barrel 4 rotate relative to each other, and then the first shielding portion 31 blocks the air outlet 41 and the first air outlet channel 81. At the same time, the second shielding portion 32 rotates from a position between the air outlet 41 and the second air outlet channel 82 to a position where the air outlet 41 and the second air outlet channel 82 are unblocked. At this time, the air guide port 33 connects the air outlet 41 and the second air outlet channel 82, and the airflow inside the hair dryer flows from the air outlet 41 through the air guide port 33 into the second air outlet channel 82.

[0076] The second state is that 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 .

[0077] Specifically, driven by the motor 5, the first barrel 3 rotates relative to the second barrel 4, and the second shielding portion 32 rotates to between the air outlet 41 and the second air outlet channel 82 as the first barrel 3 and the second barrel 4 rotate relative to each other, and then the second shielding portion 32 blocks the air outlet 41 and the second air outlet channel 82. At the same time, the first shielding portion 31 rotates from a position between the air outlet 41 and the first air outlet channel 81 to a position where the air outlet 41 and the first air outlet channel 81 are unblocked. At this time, the air guide port 33 connects the air outlet 41 and the first air outlet channel 81, and the airflow inside the hair dryer flows from the air outlet 41 through the air guide port 33 into the first air outlet channel 81.

[0078] It should be noted that the first state and the second state are two different relative positions of the air guide port 33 and the air outlet 41, which can allow the airflow to flow to different air outlet channels, and thus correspond to two different working modes of the hair dryer. For example, the first state corresponds to the concentrated air outlet mode of the hair dryer, and the second state corresponds to the surround air outlet mode of the hair dryer.

[0079] It is understandable that different numbers of air outlets 41 and air guide ports 33 can be set as needed. Depending on the different numbers of air outlets 41 and air guide ports 33, in the first state, the first blocking portion 31 and the second blocking portion 32 will simultaneously block the air outlet 41 and the first air outlet channel 81.

[0080] In some embodiments, a first limiting portion 34 is provided on the inner wall of the first cylinder 3 .

[0081] A second limiting portion 42 is disposed on the outer wall of the second cylinder 4 .

[0082] Exemplarily, one of the first limiting portion 34 and the second limiting portion 42 is a limiting protrusion, and the other is a limiting groove, and the limiting protrusion can extend into the limiting groove.

[0083] Along the circumference of the first cylinder 3 , the limiting protrusion can only rotate relatively within the limiting groove to limit the rotational angular stroke of the first cylinder 3 relative to the second cylinder 4 .

[0084] In the above technical solution, the first limiting portion 34 and the second limiting portion 42 cooperate with each other to limit the relative rotational angular travel of the first cylinder 3 and the second cylinder 4. At the same time, the first cylinder 3 and the second cylinder 4 can also be installed and positioned.

[0085] In some embodiments, the limiting protrusion is a rib extending along the axial direction of the second cylinder 4 .

[0086] Specifically, the number of ribs is multiple. In this embodiment, the number of ribs is multiple, which specifically means that the number of ribs is two, the number of ribs is three, the number of ribs is four, the number of ribs is five, etc.

[0087] Furthermore, a wire passage 43 is formed between two adjacent ribs and the inner wall of the first cylinder 3 and the outer wall of the second cylinder 4 . The wire passage 43 is configured to allow a wire connected between the motor 5 and the button 6 to pass through.

[0088] In this embodiment, the motor 5 is fixedly connected to the housing 1, the motor 5 is transmission-connected to the first cylinder 3 through its output shaft, and the second cylinder 4 is fixedly connected to the handle 2. Therefore, the ribs provided on the second cylinder 4 are stationary relative to the handle 2. Therefore, the wires in the wire passage 43 will not rotate or entangle with the rotation of the first cylinder 3, thereby causing breakage.

[0089] The two sides of the limiting groove along the circumference of the first cylinder 3 are respectively a first side 341 and a second side 342 .

[0090] When the limiting protrusion abuts against the first side 341 , the air outlet 41 and the air guide port 33 are in the first state.

[0091] When the limiting protrusion abuts against the second side 342 , the air outlet 41 and the air guide port 33 are in the second state.

[0092] By setting that when the limiting protrusion abuts against the first side 341, the air outlet 41 and the air guide port 33 are in the first state, and when the limiting protrusion abuts against the second side 342, the air outlet 41 and the air guide port 33 are in the second state, the angular travel of the relative rotation between the first cylinder 3 and the second cylinder 4 is limited.
