TECHNICAL FIELD

The present application relates to a technical field of electronic appliances for hair styling, and in particular, to a motor rotation mechanism, a hair clipping mechanism, a hair adsorption structure, an automatic hairdresser, a hair styling appliance, and a hair curling device.

BACKGROUND

The hairdresser is a hand-held hairdressing product used to perm the hair. Main components of the hairdresser include a handle and a heating roller. The existing curly hair styling method is as follows: manually winding the hair on a roller, using a relevant heating device to heat up the roller, and maintaining the curling effect for a certain period of time. In the process of manually winding the hair, the temperature of the roller is too high during use, which can easily cause burns and damage the hair. When the styling is over, it is difficult to obtain a better stereotyped effect. In addition, the hair clipping mechanism is not effective, and it is easy to clip the scalp, thereby reducing the user experience.

Therefore, how to design a hairdresser which can automatically curl hair, avoid scalding and not damage the hair is a technical problem needs to be solved.

Based on the above structure, when the air is blown out from the air outlet slot, a negative pressure area will appear in a direction opposite to the blowing direction. At this time, the hair ends in the negative pressure area can be sucked and blown, so that the hair can be smoothly placed in the gap. Through the above method, the orderliness of the hair winding is ensured, and it is beneficial to obtain a better styling effect.

In view of the deficiencies in the above technologies, the present application also provides a hair styling appliance. In order to solve the above-mentioned technical problems, the technical solution adopted in this application is:

DETAILED DESCRIPTION

In order to make the above objects, features and advantages of the present application more clearly understood, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

The terms “comprising” and “including” and any variations thereof in this application are intended to cover a non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or elements is not limited to the listed steps or elements, but may optionally also include unlisted steps or elements; or, optionally, other steps or units inherent to these processes, methods, products or devices are also included.

Reference herein to an “embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor a separate or alternative embodiment that is mutually exclusive of other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

As shown inFIG.1toFIG.12, the present application provides an automatic hairdresser which includes: a handle1with an air duct inside, a fan5configured to guide air in the air duct, a heating element4configured to heat the air guided in the air duct, a hair curling post2rotatably arranged at one end of the handle1, and a motor rotation mechanism disposed in the handle1and configured to rotate the hair curling post2. Wherein, the air duct has an inlet end and an outlet end. The handle1is provided with a plurality of air inlet holes10communicating with the inlet end of the air duct. The hair curling post2is provided with an air outlet portion communicating with the outlet end of the air duct.

Specifically, both the motor rotation mechanism and the fan5can operate independently; and the heating element4can cooperate with the fan5to operate.

For convenience of description, in this application, an installation direction of the hair curling post2is defined as a front end, and an installation direction of the handle1is defined as a rear end.

It is understandable that the present application allows for quick automatic styling of hair. The process of quick automatic styling is as follows: securing the end of a strand of hair to the hair curling post2; activating the motor rotation mechanism to wind the hair on the hair curling post2clockwise/counterclockwise; and operating the heating element4and the fan5simultaneously. Under the action of the fan5, the air enters the air duct from the air inlet holes10. The air guided in the air duct is heated by the heating element4, and the hot air is discharged to the hair by the air outlet portion. In the above-described manner, the hair wound on the hair curling post2can be styled quickly and automatically.

When the hair is finished styling, the present application allows for quick styling of the hair. In the process of quick styling, the fan5is operated alone. Under the action of the fan5, the air enters the air duct from the air inlet holes10, and the cool air is discharged to the styled hair by the air outlet portion. As a result, the hair wound on the hair curling post2can be quickly styled.

Of course, in this application, the motor rotation mechanism can also be disabled from beginning to end. The heating element4and the fan5can be operated according to the needs of use, so as to manually perform hair modeling and styling.

In one embodiment, a mounting bracket assembly is fixed in the handle1, and the air duct is formed in the mounting bracket assembly.

Specifically, the mounting bracket assembly includes a first mounting bracket121and a second mounting bracket122which can be fastened to each other. Wherein, the first mounting bracket121and the second mounting bracket122are substantially half-cylindrical shells, and after the two are fastened together, a cylindrical shell can be formed. That is, the air duct is formed in the cylindrical shell.

Furthermore, the heating element4includes a heating wire mounting bracket41. A ventilation cavity (not shown in the drawings) is formed inside the heating wire mounting bracket41. A heating wire (not shown in the drawings) is wound around the ventilation cavity. The air guided by the fan5can all flow through the ventilation cavity. When the heating wire is energized, it can effectively heat the guided air.

Furthermore, two ends of the heating wire mounting bracket41are provided with a plurality of limiting plates42which can limit the heating wire in the ventilation cavity. As a result, the heating wire can be prevented from coming out of the heating wire mounting bracket41, and two ends of the ventilation cavity can be in a state of air circulation.

In the specific application scenario of the present application, the number of limiting plates42at each end of the heating wire mounting bracket41is six. The limiting plates42are uniformly fixed to the heating wire mounting bracket41along a circumferential direction of the heating wire mounting bracket41.

In order to improve the heating efficiency of the flowing air, the heating element4is restricted to be arranged in the air duct. At the same time, in order to improve the air conduction efficiency, the fan5is also restricted to be arranged in the air duct.

Wherein, the heating element4may be arranged at a front of the fan5or at a rear of the fan5. Considering that the longer the heated air flows, the greater the heat loss; and when the heated air blows to the fan5, the service life of the fan5will be affected; therefore, the heating element4is preferably arranged at the front end of the air duct, and the fan5is preferably arranged at the rear of the heating element4.

In addition, a shock-absorbing ring50is sleeved on the fan5to reduce the vibration effect of the fan5on the mounting bracket assembly and the handle1, and to reduce vibration noise.

As an embodiment of the present application, the motor rotation mechanism includes a motor31fixed in the handle1, a connecting plate32rotatably arranged in the front of the air duct, and a transmission assembly33for transmitting rotational power between the motor31and the connecting plate32. Wherein, the hair curling post2is fixedly connected to the connecting plate32.

In the present application, the motor31may be arranged in the air duct, in front of the air duct, or at a rear of the air duct. Considering that a blocking surface of the motor31to the flowing air is relatively large, the motor31is not suitable to be arranged in the air duct or at the front of the air duct. In addition, when the heated air blows toward the motor31, the service life of the motor31will be affected; therefore, it is preferable to arrange the motor31at the rear of the air duct.

Furthermore, the transmission assembly33includes a driving gear331fixed to an output shaft of the motor31, a driven gear332meshing with the driving gear331, and a gear set rotating synchronously with the driven gear332.

Specifically, the gear set includes a first gear334fixedly connected to the driven gear332through a rotating shaft333, a second gear336fixedly connected to the connecting plate32, and a third gear335. The third gear335is meshing with the first gear334and the second gear336to transmit rotational power.

Furthermore, the power transmission between the motor31and the connecting plate32is not limited to the use of gears, and other transmission structures such as a transmission belt can also be used.

Considering that the hair curling post2needs to be fixed with the connecting plate32, and the flowing air needs to pass through the connecting plate32and flow to the hair curling post2, it is limited that the connecting plate32is arranged at a front port of the handle1, and a plurality of through grooves320are formed on the connecting plate32.

In a specific application scenario, since the hair curling post2needs to be disassembled frequently for maintenance, or it may also be necessary to install other hairdressing accessories, such as a straightening comb and a hair dryer, on the handle1, the hair curling post2and the connecting plate32are designed to be connected in a quick-detachable manner. Specifically, a snap connection, a threaded connection, a quick-plug connection or other connection manners that can be quickly detached may be used between the hair curling post2and the connecting plate32, which is not limited in this application.

The automatic hairdresser in the present application also includes a printed circuit board6for controlling and operating the motor rotation mechanism, the heating element4and the fan5. Since the printed circuit board6has heating elements which will generate heat during operation; in view of this, the printed circuit board6is preferably arranged in the air duct, and an installation plane of the printed circuit board6is parallel to a flow direction of the air in the air duct. In this way, the printed circuit board6can block the air duct as little as possible, and at the same time, the flowing cold air can effectively reduce the temperature rise of the heating elements, thereby prolonging the service life of the elements.

Specifically, the printed circuit board6may be disposed between the heating element4and the fan5, or may be disposed at a rear of the heating element4and the fan5. Preferably, the printed circuit board6is disposed at the rearmost end of the air duct.

As an embodiment of the present application, the plurality of air inlet holes10communicating with the air duct are arranged at a rear side of the handle1along a circumferential direction of the handle1. A filter screen13for filtering the air is disposed between the air inlet holes10and the air duct.

Specifically, a rear end of the mounting bracket assembly (i.e., the inlet end of the air duct) is fixedly clamped with a filter screen holder130for supporting the filter screen13. A filter screen bottom plate14for restricting the filter screen13on the filter screen holder130is detachably provided at a rear of the filter screen holder130.

Furthermore, a lower bottom plate15is detachably connected to the rear of the filter screen bottom plate14, and the lower bottom plate15is configured to block a rear port of the filter screen13.

Specifically, the filter screen bottom plate14is provided with a plurality of twist grooves141, and the lower bottom plate15is provided with a plurality of twist buttons151which are configured to be correspondingly buckled with the twist grooves141. The twist groove141is L-shaped. As a result, the lower bottom plate15can be easily detached from the filter screen bottom plate14.

A rear bottom plate11is fixed at the rear port of the handle1, and the rear bottom plate11is used to block the rear port of the handle1. Wherein, the rear bottom plate11is provided with a first power cord opening (not shown in the drawings). The lower bottom plate is provided with a plurality of rear air inlet holes150communicating with the air duct and a second power cord opening (not shown in the drawings).

In a specific application scenario, a power cord can pass through the first power cord opening, the second power cord opening and the filter screen holder130so as to be connected to the printed circuit board6.

As an embodiment of the present application, the hair curling post2includes an integrally formed end shell21and a half-post shell assembly22; wherein, the end shell21of the hair curling post2can be quickly detached and fixed to the connecting plate32.

Furthermore, an outer surface of the half-post shell assembly22is substantially cylindrical, and includes two half-post shells23. The two half-post shells23are arranged opposite to each other and form a gap20between the two half-post shells23. Wherein, the two half-post shells23are integrally formed at a front of the end shell21.

Specifically, each half-cylindrical shell23includes a ventilation cavity230formed therein. The end shell21is provided with a connecting cavity210which communicates with the ventilation cavities230and the air duct. Wherein, the air outlet portion is configured to communicate with the ventilation cavities230. It is understandable that the cold air/hot air blown from the air duct can all flow through the connecting cavity210, and be divided into the two ventilation cavities230, and then be blown onto the hair from the air outlet portions arranged on the half-post shells23.

The air outlet portion in this application includes an air outlet slot231. The air outlet slot231is configured to communicate with the ventilation cavity230, and is obliquely opened on a side of the half-post shell23facing the gap20.

Referring toFIG.11andFIG.12, the two air outlet slots231correspondingly opened on the two half-cylindrical shells23are symmetrically arranged with a central plane of the gap as a symmetrical plane. An included angle α is formed between an inclination direction of the air outlet slot231and the center plane of the gap20. Based on the above structure, when the two air outlet slots231blow air outward, a negative pressure area will be generated in an opposite direction of the air blowing direction. At this time, if the end of the hair is placed in the negative pressure area, the wind blown out through the air outlet slots231can blow the hair along the blowing direction, and then the hair can be placed in the gap20smoothly.

The inclination direction of the air outlet slot231is obliquely downward. In a specific application scenario, when the included angle α is too large, the air blown from the two air outlet slots231will collide, and it is not easy to create a significant negative pressure area above the gap20. Therefore, it is limited that the included angle α should not be too large, and preferably the included angle α should be no greater than 45°.

The air outlet portion in this application also includes a plurality of air outlet holes24. The air outlet holes24are configured to communicate with the ventilation cavity230. The air outlet holes24are opened on a side of the half-post shell23facing away from the gap20, and are configured to perform hot air styling or cold air styling on the hair wound on the hair curling post2.

Furthermore, each front end of the two half-post shells23includes a chamfer27. The two chamfers27form an outwardly flared opening which communicates with the gap20. A user can place the hair in the gap20through the opening, and then place the hair in the gap20smoothly through the wind blown from the air outlet slot231.

In addition, in the prior art, some of the existing hair curlers lack a hair clipping mechanism, and the user only relies on the winding force to fix the hair on a heating roller. In this way, the hair is easy to scatter, and it is difficult to achieve a better curly hair effect. Some other existing hair curlers are also provided with a hair clipping mechanism. The hair clipping mechanism can completely fix the end of the hair on the heating roller, so that the hair is not easily scattered. However, when more hair is clipped or the curling force is stronger, this completely fixed manner will cause the hair to have a strong sense of pinching, thereby reducing the user experience. The user needs to manually place the ends of the hair on the heating roller for fixing. Since there is no external pressure after placing, it will cause the hair to become loose after releasing the hand, which not only affects the orderliness of the hair curling, but also makes it difficult to achieve a better styling effect.

In view of this, in order to improve the stability of the hair being wound around the hair curling post2, a hair clipping mechanism is provided on the hair curling post2. The hair clipping mechanism includes two oppositely arranged clipping plate fixing plates25, two clipping plates26correspondingly slidably arranged on the two clipping-plate fixing plates25, and a spring disposed between the clipping-plate fixing plate25and the clipping plate26.

Wherein, the two clipping-plate fixing plates25are correspondingly fixed on the sides of the two half-post shells23facing the gap20. Under the action of the spring, the two clipping plates26can abut against each other so as to clip the hair.

Specifically, the spring is a compression spring.

Specifically, the inclination direction of the air outlet slot231is toward the hair clipping mechanism.

Furthermore, a recessed portion251is provided at a middle portion of the clipping plate fixing plate25toward the side of the gap20. The end positions of the two clipping plate fixing plates25are abutted against each other and fixed together, so that the two recessed portions251constitute a placement opening for passing the hair.

An accommodating cavity250is provided on the clipping plate fixing plate25. The clipping plate26can be retracted into the accommodating cavity250to expose the placement opening. In addition, when there is a lot of hair between the two clipping plates26, the spring will be compressed, so that the hair does not have a pinch feeling, which improves the user experience.

The clipping plate26is provided with a guide rod261inserted to the clipping plate fixing plate25for improving the sliding stability between the clipping plate fixing plate25and the clipping plate26.

As an embodiment of the present application, the hair curling post2is also provided with a trigger structure configured to keep the two clipping plates26away from each other. The trigger structure can correspondingly retract the two clipping plates26into the two accommodating cavities250. After the hair has passed through the placement opening, the trigger structure is released so as to hold the hair between the two clipping plates26.

Specifically, the trigger structure can be a mechanical structure or an automated electromechanical structure. The trigger structure can realize the function of pushing or pulling the two clipping plates26away from each other, which is not limited in this application.

In summary, the present application includes the fan5for guiding the air in the air duct, the heating element4for heating the air guided in the air duct, the hair curling post2rotatably disposed at one end of the handle1, and the motor rotation mechanism configured to rotate the hair curling post2. Based on the above-described structure, the hair curling post2can automatically curl the hair, and the hair wrapped around the hair curling post2can be quickly styled under the action of the hot air. When the hair is styled, the fan5is controlled to run independently, and the air outlet portion can blow cold air to the hair, so that the hair can be quickly styled.

As shown inFIG.13toFIG.20, the present application provides a hair styling appliance including: a handle1for an operator to hold, the handle1having an air duct formed inside the handle1; a rod body1002disposed at one end of the handle1, an inside the rod member1002being hollow to form an accommodating cavity communicating with the air duct; a first heating element3disposed in the accommodating cavity and configured to heat the rod body1002; a second heating element1004configured to cooperate with the first heating element3for auxiliary heating; and a fan5configured to blow air. Wherein, the air duct has an inlet end and an outlet end. The handle1is provided with a plurality of air inlet holes10communicating with the inlet end of the air duct. A plurality of air outlet holes24are formed on an outer peripheral surface of the rod body1002and communicate with the outlet end of the air duct. The air outlet holes24communicate with the air duct through the accommodating cavity. The fan5makes the air flow in the air duct flow out through the air outlet holes24after entering the accommodating cavity.

Specifically, the rod body1002includes a styling state when the first heating element3and the second heating element1004are heated, and a styled state when the first heating element3and the second heating element1004are not heated.

For convenience of description, in this application, an installation direction of the rod body1002is defined as a front end, and an installation direction of the handle1is defined as a rear end.

It is understandable that the present application allows for quick styling of hair. During the quick styling process, the first heating element3, the second heating element1004and the fan5operate together. Under the action of the fan5, the air enters the air duct from the air inlet holes10. The second heating element1004heats the air guided in the air duct, and discharges the hot air through the air outlet holes24. At the same time, the first heating element3can heat the rod body1002. In the above manner, the hair wound on the rod body1002can be quickly styled under the dual action of the rod body1002and the hot air.

When the hair is finished styling, the present application allows for quick styling of the hair. During the process of quick styling, the first heating element3and the second heating element1004stop working, that is, the fan5operates independently. Under the action of the fan5, the air enters the air duct from the air inlet holes10, and the cool air is discharged to the styled hair through the air outlet holes24, so that the hair can be quickly styled.

As an embodiment of the present application, the rod body1002is substantially cylindrical, and is disposed at the front end of the handle1in a quick-detachable manner. A sealing gasket1023is disposed at the connection between the rod body1002and the handle1.

In a specific application scenario, the rod body1002and the handle1may adopt a snap connection, a screw connection, a quick-plug connection or other connection manners that can be quickly disassembled, which are not limited in this application.

The first heating element3is disposed inside the rod body1002. The first heating element3includes a plurality of PTC resistor plates1033and a resistor plate mounting bracket for mounting the PTC resistor plates1033. In order to improve the heating efficiency of the rod body1002, the PTC resistor plates1033are preferably attached to an inner wall of the rod body1002.

Specifically, the resistor plate mounting bracket30includes a shaft rod1031arranged along a length direction of the rod body1002and a plurality of holders1032arranged on the shaft rod1031along a circumferential direction of the shaft rod1031. Wherein, the holder1032is composed of two fixing plates321arranged opposite to each other. A space322for inserting the PTC resistor plate1033is formed between the two fixing plates321.

In order to ensure that the first heating element3can evenly heat the rod body1002, the number of the PTC resistor plates1033and the holders1032is defined to be multiple, and they are evenly arranged in the rod body1002.

The more the number of PTC resistor plates1033is, the better the heating uniformity effect of the rod body1002is. However, when there are too many PTC resistor plates1033, the air volume leading to the air outlet holes24will be affected. Therefore, in a specific application scenario, the number of the PTC resistor plates1033should be appropriate, and preferably the number is 3 to 6.

Furthermore, the holder1032is provided with a rear limit block324. The rear limit block324is disposed at a rear of the space322for limiting the rear end of the PTC resistor plate1033. A front limit block1021is provided in a front end of the rod body1002. The front limit block1021is configured to abut against the front ends of the holder1032and the PTC resistor plates1033, and is used to limit the front ends of the holder1032and the PTC resistor plates1033.

Furthermore, a top cover1022is clamped on a front end of the rod body1002. The top cover1022and the shaft rod1031are fixedly connected by a first fastener221. Based on the above structure, the relative positions of the top cover1022, the rod body1002and the resistor plate mounting bracket30can be fixed. In addition, the PTC resistor plate1033can be stably inserted into the space322under the joint limitation of the front limit block1021, the rear limit block324and the inner wall of the rod body1002.

The first fastener221is a bolt, a screw, a rivet or others, which is not limited in this application.

In one embodiment, in order to prevent the fixing plate321from bearing the heat generated by the PTC resistor plate1033too much, a plurality of heat sinks323are provided on a side of the fixing plate321facing away from the space322, so that the heat dissipated by the heat sinks323is carried out from the air outlet holes24by the flowing air. It can also be understood that the plurality of heat sinks323are disposed on a side of the holder1032.

Specifically, the shaft rod1031is provided with an air-inducing groove (not shown in the drawings) with an open rear end along its length direction. A slot310communicating with the air-inducing groove is disposed between two adjacent holders1032. Based on the above structure, part of the air guided by the fan5can pass through the air-inducing groove and be blown toward the heat sink323from the slot310. This not only effectively controls the temperature rise of the heat sink323, but also reduces the influence of the shaft rod1031on the resistance of the air flow.

As an embodiment of the present application, the second heating element1004includes a heating wire mounting bracket41. A ventilation cavity (not shown in the drawings) is formed inside the heating wire mounting bracket41. A heating wire (not shown in the drawings) is wound around the ventilation cavity. The air guided by the fan5can all flow through the ventilation cavity. When the heating wire is energized, it can effectively heat the guided air.

Furthermore, two ends of the heating wire mounting bracket41are provided with a plurality of limiting plates42which can limit the heating wire in the ventilation cavity. As a result, the heating wire can be prevented from coming out of the heating wire mounting bracket41, and two ends of the ventilation cavity can be in a state of air circulation.

In the specific application scenario of the present application, the number of limiting plates42at each end of the heating wire mounting bracket41is six. The limiting plates42are uniformly fixed to the heating wire mounting bracket41along a circumferential direction of the heating wire mounting bracket41.

In one embodiment, a mounting bracket assembly12is fixed in the handle1, and the air duct is formed in the mounting bracket assembly12.

Specifically, the mounting bracket assembly12includes a first mounting bracket121and a second mounting bracket122which can be fastened to each other. Wherein, the first mounting bracket121and the second mounting bracket122are substantially half-cylindrical shells, and after the two are fastened together, a cylindrical shell can be formed. That is, the air duct is formed in the cylindrical shell.

In order to improve the heating efficiency of the flowing air, the second heating element1004is restricted to be arranged in the air duct. At the same time, in order to improve the air conduction efficiency, the fan5is also restricted to be arranged in the air duct.

Wherein, the second heating element1004may be arranged at a front of the fan5or at a rear of the fan5. Considering that the longer the heated air flows, the greater the heat loss; and when the heated air blows to the fan5, the service life of the fan5will be affected; therefore, the second heating element1004is preferably arranged at the front end of the air duct, and the fan5is preferably arranged at the rear of the second heating element1004.

In addition, a shock-absorbing ring50is sleeved on the fan5to reduce the vibration effect of the fan5on the mounting bracket assembly12and the handle1, and to reduce vibration noise.

The present application also includes a printed circuit board6for controlling and operating the first heating element3, the second heating element1004and the fan5. Since the printed circuit board6has heating elements which will generate heat during operation; in view of this, the printed circuit board6is preferably arranged in the air duct, and an installation plane of the printed circuit board6is parallel to a flow direction of the air in the air duct. In this way, the printed circuit board6can block the air duct as little as possible, and at the same time, the flowing cold air can effectively reduce the temperature rise of the heating elements, thereby prolonging the service life of the elements.

Specifically, the printed circuit board6is disposed at the rearmost end of the air duct.

As an embodiment of the present application, the hair styling appliance further includes a hair clipping plate7. The hair clipping plate7is pivotally connected to the front side of the handle1through the plate sleeve8and can be pressed against the outside of the rod body1002. The hair clipping plate7is configured to clip the end of a strand of hair between the hair clipping plate7and the rod body1002, so that the hair can be easily wound on the rod body1002.

In order to make the hot air/cold air blown out from the air outlet holes24better blow to the hair, a plurality of ventilation holes70are formed on the hair clipping plate7.

Furthermore, the hair clipping plate7is fixedly connected with the plate sleeve8through a second fastener71. An elastic member9for restoring the plate sleeve8is disposed between the handle1and the plate sleeve8. It is understandable that the hair clipping plate7and the plate cover8are fixed in one piece. The elastic member9can bounce the hair clipping plate7and the plate sleeve8, so that the hair clipping plate7cooperates with the rod body1002to clip the hair.

Wherein, the second fastener71is a bolt, a screw, a rivet or others, which is not limited in this application. The elastic member9may be a torsion spring or a compression spring. One end of the elastic member9is fixed on the handle1through a fixing seat91.

Specifically, the plate sleeve8is provided with a pressing plate81which is convenient for opening the hair clipping plate7.

Furthermore, rotating shafts1011are fixed on two sides of the handle1along its width direction, and the plate sleeve8is pivotally connected to the two rotating shafts1011.

Specifically, the rotating shaft1011is fixed on the handle1by a third fastener111. The third fastener111can pass through the handle1and be screwed on the mounting bracket assembly12, so that the positions of the mounting bracket assembly12and the handle1are relatively fixed.

Wherein, the third fastener111is one of a bolt, a screw and a stud.

In one embodiment, the plurality of air inlet holes10communicating with the air duct are arranged at a rear side of the handle1along a circumferential direction of the handle1. A filter screen13for filtering the air is disposed between the air inlet holes10and the air duct.

Specifically, a rear end of the mounting bracket assembly12(i.e., the inlet end of the air duct) is fixedly clamped with a filter screen holder130for supporting the filter screen13. A filter screen bottom plate14for restricting the filter screen13on the filter screen holder130is detachably provided at a rear of the filter screen holder130.

Furthermore, a lower bottom plate15is detachably connected to the rear of the filter screen bottom plate14, and the lower bottom plate15is configured to block a rear port of the handle1.

Specifically, the filter screen bottom plate14is provided with a plurality of twist grooves141, and the lower bottom plate15is provided with a plurality of twist buttons151which are configured to be correspondingly buckled with the twist grooves141. The twist groove141is L-shaped. As a result, the lower bottom plate15can be easily detached from the filter screen bottom plate14.

In the present application, the lower bottom plate15is provided with a plurality of rear air inlet holes150communicating with the air duct, and a power cord opening (not shown in the drawings). The power cord can pass through the power cord opening and the filter screen holder130so as to be connected to the printed circuit board6.

In summary, the present application includes the fan5for guiding air in the air duct, the second heating element1004for heating the air guided in the air duct, and the first heating element3for heating the rod member1002. Based on the above structure, the hair wound on the rod body1002can be quickly styled under the dual action of the heated rod body1002and the hot air. When the hair is styled, the fan5is controlled to run alone, and the cold air can be blown from the air outlet holes24to the hair, so that the hair can be quickly styled.

As shown inFIG.21andFIG.22, a hair curling device includes a handle2001; and a styling body2002connected to the handle2001. The styling body2002includes an outer shell2021for hair to be wound around. An air outlet hole2210is formed on the outer shell2021. The styling body2002further includes a hair clipping gap2008disposed on an inner side of the outer shell2021. Two sides of the hair clipping gap2008are respectively provided with a clipping member2023. At least one clipping member2023is connected to a transmission mechanism to operably extend or retract toward the hair clipping gap2008. By providing the hair clipping gap2008for holding the hair, the hair curling device can realize the flexible opening and closing of the hair clipping gap2008through a simple and compact transmission mechanism, without worrying about the hair slipping and causing styling failure.

Wherein, the transmission mechanism includes an inclined surface matching structure. The inclined surface matching structure operatively converts an external force acting on the hair curling device into an extension or contraction movement of the clipping member2023toward the hair clipping gap2008, so that the operation of the hair curling device has flexibility.

Referring toFIG.23toFIG.28, the transmission mechanism includes an operable moving bracket2003, a support plate2024disposed in parallel with the clipping member2023, a first inclined surface matching structure disposed between the moving bracket2003and the support plate2024, and a second inclined surface matching structure disposed between the support plate2024and the clipping member2023. The first inclined surface matching structure converts a movement of the moving bracket2003along a first direction into a lifting movement of the support plate2024relative to the styling body. The second inclined surface matching structure converts the lifting movement of the support plate2024into a telescopic movement of the clipping member2023along a second direction.

In other words, the inclined surface matching structure includes the first inclined surface matching structure disposed between the moving bracket2003and the support plate2024, and the second inclined surface matching structure disposed between the support plate2024and the clipping member2023. The two inclined surface matching structures both play the role of converting the direction of movement. The first inclined surface matching structure converts the movement in the first direction into a lifting movement along an extending direction of the styling body2002. The second inclined surface matching structure converts the lifting movement into the telescopic movement in the second direction.

The present application provides two preferred embodiments of the first inclined surface matching structure, which will be described separately below.

Referring toFIG.23toFIG.25, in a first preferred embodiment, the first direction is a lateral direction, and the second direction is also the lateral direction. The first direction and the second direction are separated by a longitudinal distance. The moving bracket2003is operable to translate in the lateral direction. A sliding rail2004for the relative movement of the moving bracket2003is fixed in the styling body2002. Preferably, a spring (not shown in the drawings) is disposed between the moving bracket2003and the sliding rail2004. After the hair is put into the hair clipping gap2008, the moving bracket2003is released, the spring moves the moving bracket2003relative to the sliding rail2004to an initial position, the support plate2024moves downwardly, and the clipping member2023moves toward a direction of the hair clipping gap2008, so that the hair clipping gap2008is closed again.

The moving bracket2003is also provided with an operation portion2035for the user to operate. In this embodiment, a shell of the styling body2002is provided with a receiving hole2212. The operation portion2035at least partially protrudes out of the shell through the receiving hole2212, so that the user can press to move the moving bracket2003relative to the sliding rail2004in the first direction.

Referring toFIG.25, the first inclined surface matching structure includes a first inclined portion2031provided on the moving bracket2003and a first sliding portion2241provided on the support plate2024. Of course, exchanging the positions of the first inclined portion2031and the first sliding portion2241can also convert the translational movement of the moving bracket2003along the first direction into the vertical lifting movement of the support plate2024.

The height of the first inclined portion2031decreases along the moving direction of the moving bracket2003, so that the first sliding portion2241is located at a bottom position of the first inclined portion2031in the initial state. When the operation portion2035is pressed to move the moving bracket2003, the first sliding portion2241climbs upward relative to the first inclined portion2031.

The first sliding portion2241is an arc surface, which is beneficial to reduce sliding resistance. The first inclined portion2031is a straight inclined surface.

The first inclined surface matching structure further includes a limiting portion2033. The limiting portion2033is disposed on the first inclined portion2031to prevent the first sliding portion2241from being separated from the first inclined portion2031.

Referring toFIG.26toFIG.28, in a second preferred embodiment, the styling body2002is set to extend along a longitudinal direction. The first direction is a circumferential direction around the longitudinal direction. The moving bracket2003′ is operable to rotate in the circumferential direction.

Referring toFIG.28, the first inclined surface matching structure includes a first inclined portion2031′ provided on the moving bracket2003′ and a first sliding portion2241provided on the support plate2024. Of course, exchanging the positions of the first inclined portion2031′ and the first sliding portion2241can also convert the translational movement of the moving bracket2003′ along the first direction into the vertical lifting movement of the support plate2024.

The height of the first inclined portion2031′ decreases along the moving direction of the moving bracket2003′, so that the first sliding portion2241is located at a bottom position of the first inclined portion2031′ in the initial state. When the operation portion2035′ is pressed to move the moving bracket2003′, the first sliding portion2241climbs upward relative to the first inclined portion2031′.

Wherein, the first sliding portion2241is an arc surface, which is beneficial to reduce sliding resistance. The first inclined portion2031′ is a spiral inclined surface.

The first inclined surface matching structure further includes a limiting portion2033′. The limiting portion2033′ is provided on the first inclined portion2031′ to prevent the first sliding portion2241from being separated from the first inclined portion2031′.

In the second embodiment, the moving bracket2003′ is a circular ring. A protruding operation portion2035′ is provided on the moving bracket2003′. The shell of the styling body2002is provided with a receiving hole2212′. The operation portion2035′ at least partially protrudes out of the shell through the receiving hole2212′, so as to facilitate the user to operate.

Referring toFIG.23andFIG.26, the styling body2002includes an outer shell2021and an inner bracket2022. In this embodiment, the outer shell2021is integrally formed. The hair clipping gap2008inside the outer shell2021is Y-shaped, and an opening thereof tends to decrease from the top to the bottom, so as to facilitate placing the hair. Correspondingly, the inner bracket2022also has a Y-shaped opening.

Referring toFIG.25andFIG.28, the styling body2002includes a mounting sleeve2009. The inner bracket2022is assembled by two half shells which are inserted into the mounting sleeve2009.

A groove is formed inwardly on one side of the inner bracket2022close to the clipping member2023, so as to accommodate the clipping member2023when retracted. A positioning post2221is arranged in the groove. The support plate2024is provided with a positioning hole2026for receiving the positioning post2221. The positioning hole2026is configured in an oval shape, so that the support plate2024can be displaced in a longitudinal direction. The arrangement of the positioning post2221and the positioning hole2026restricts the movement direction of the support plate2024, and only allows the support plate2024to move up and down in the longitudinal direction.

Referring toFIG.24andFIG.25, in the first embodiment, the second inclined surface matching structure includes a second inclined portion2243provided on the support plate2024and a second sliding portion2242provided on the clipping member2023. The second sliding portion2242is slidably matched with the second inclined portion2243and pushes the clipping member2023to translate. Of course, the positions of the second inclined portion2243and the second sliding portion2242can also be exchanged to each other to convert the lifting movement of the support plate2024into the translational movement of the clipping member2023in the second direction.

Specifically, the second inclined portion2243extends from the support plate2024toward the clipping member2023. The second sliding portion2242extends from the clipping member2023toward the support plate2024. A free end of the second inclined portion2243is provided with a barb2245to prevent the second sliding portion2242from slipping off.

In this embodiment, the second inclined portion2243is inclined upwardly. That is, the second inclined portion2243is provided at an acute angle with respect to an ascending direction of the support plate2024. In this way, the rising of the support plate2024drives the second inclined portion2243to rise, so that the second sliding portion2242slidingly matched with the second inclined portion2243moves downwardly along the slope of the second inclined portion2243relatively. The second sliding portion2242approaches a direction of the support plate2024to complete a retracting action of the clipping member2023away from the hair clipping gap2008.

Referring toFIG.26toFIG.28, the second inclined surface matching structure in the second preferred embodiment is the same as the second inclined surface matching structure in the first embodiment, and thus will not be repeated.

In the hair curling device in the two embodiments of the present application, in the initial state, the hair clipping gap2008is closed. When the hair curling device needs to be used, the user operates the moving bracket2003(2003′) through the operation portion2035(2035′), so that the clipping member2023is retracted in a direction away from the hair clipping gap2008. The user places hair into the hair clipping gap2008. After the hair is placed successfully, release the operation portion2035(2035′), so that the moving bracket2003(2003′) moves under the action of the elastic restoring force and drives the clipping member2023back to the initial state; or reversely operate the moving bracket2003(2003′), so that the moving bracket2003(2003′) moves in a reverse direction to drive the clipping member2023to return to the initial position. As a result, putting the hair is completed.

In summary, the hair curling device provided by the present application includes the hair clipping gap2008and the clipping member2023actuated by the mechanical transmission mechanism, so that the user can fix a section of the hair before curling the hair. Then, the hair is rotated around the shell2021. Finally, the curling hair is shaped under the action of hot air, and the styling is completed under the action of cold air. Such a structure is convenient for fixing the hair and avoids the failure of the curling due to the hair slipping during the styling process.

Referring toFIG.29toFIG.34, a hair curling device includes: a handle401; a styling body402connected with the handle401, the styling body402including an outer shell421for hair to be wound around, the outer shell421being provided with an air outlet hole4210; and a transmission mechanism disposed between the handle401and the styling body402. The styling body402further includes a hair clipping gap408arranged on an inner side of the outer shell421. Two sides of the hair clipping gap408are provided with a clipping member423, respectively. At least one of the clipping members423is connected to the transmission mechanism to operably extend and retract toward the hair clipping gap408.

The hair curling device includes the hair clipping gap408for holding the hair, and can realize flexible opening and closing of the hair clipping gap408through the simple and compact transmission mechanism. As a result, there is no need to worry about the styling failure due to slipping of the hair.

The transmission mechanism is configured as a linkage mechanism. The linkage mechanism includes a sliding member403and a swinging member404. One end of the swinging member404is pivotally connected to the sliding member403. The other end of the swinging member404is pivotally connected to the clipping member423. The swinging member404converts a translational movement of the sliding member403in the first direction into a telescopic movement of the clipping member423. Two ends of the swinging member404are pivotally connected to the sliding member403and the clipping member423respectively, so as to convert the translational movement of the sliding member403along the first direction into the telescopic movement of the clipping member423. It is needless to say that the direction of the telescopic movement of the clipping member423is perpendicular to the first direction.

Each of the two clipping members423is connected with one linkage mechanism. The two linkage mechanisms share the sliding member403. The swinging members404of the two linkage mechanisms are disposed on two sides of the sliding member403, respectively. Of course, in other embodiments, one clipping member423can also be kept stationary, while the other clipping member423is connected to and driven by the linkage mechanism.

The present application provides two preferred embodiments, whereinFIG.31andFIG.32illustrate a first embodiment, andFIG.33andFIG.34illustrate a second embodiment. One of the differences between the two embodiments is that the first direction of the sliding member403that triggers the movement of the clipping member423is different.

Referring toFIG.31andFIG.32, the first direction is parallel to a longitudinal axis direction of the styling body402. Two swinging members404are connected to two sides of the sliding member403, respectively. The two swinging members404on a same side are arranged parallel to each other. Each of the two sides of the sliding member403is provided with two swinging members404. Moreover, by arranging the two swinging members404on the same side in parallel, it is beneficial to transmit the power of the sliding member403more reliably, and the balance of the sliding members403can also be better maintained.

Furthermore, the linkage mechanism includes two sliding members403. One end of the swinging member404is located between the two sliding members403. The swinging member404and the sliding member403are connected by a pin. In a preferred embodiment, the swinging member404is clamped between the two sliding members403. One end of the four swinging members404is pivotably connected to the sliding member403through pins.

In the above first embodiment, the sliding member403translates along the longitudinal axis direction of the styling body402to drive one end of the swinging member404to move in the same direction. However, the other end of the swinging member404is connected with the clipping member423and is limited by the clipping member423along the longitudinal axis direction. The swinging member404reverses the direction of movement and causes the clipping member423to move in the direction of extending or retracting to the hair clipping gap408.

The clipping member423includes a support plate424. The support plate424is connected with the linkage mechanism. In this embodiment, the support plate424has a connecting portion extending along the longitudinal axis direction of the styling body402. The connecting portion and the swinging member404are connected by a pin.

Referring toFIG.31andFIG.32, the clipping member423further includes a floating clipping plate425disposed on a side of the support plate424close to the hair clipping gap408. A restoring member (not shown) is provided between the floating clipping plate425and the support plate424. The elastic restoring force of the restoring member biases the floating clipping plate425toward the hair clipping gap408. The arrangement of the floating clipping plate425enables the clipping member423to have a certain space for avoidance. After the hair is put into the hair clipping gap408, if there are too many hairs, the floating clipping plate425can be retracted toward the support plate424to prevent the hair from being clipped too tightly. With this arrangement, the hair curling device can be adapted to the needs of users with different volumes of hair. In this embodiment, the floating clipping plate425is provided with a positioning post426, and the support plate424is provided with a guide hole for receiving the positioning post426. The restoring member is a spring which is sleeved on the positioning post426.

Continuing to refer toFIG.31andFIG.32, the styling body402includes an outer shell421and an inner bracket422. The inner bracket422is recessed toward the outer shell421so as to form an accommodating cavity for accommodating the clipping member423. When the clipping member423retracts, the support plate424and the floating clipping plate425enter the accommodating cavity. The accommodating cavity of the inner bracket422provides a lateral movement space for the clipping member423and also restricts the movement of the clipping member423along the longitudinal axis direction of the styling body402.

In this embodiment, the outer shell421is integrally formed. The hair clipping gap408of the outer shell421is Y-shaped, and an opening thereof tends to decrease from the top to the bottom, which facilitates placing the hair. Correspondingly, the inner bracket422also has a Y-shaped opening, and the inner bracket422is also integrally formed.

Referring toFIG.33andFIG.34, a second embodiment is provided for this application. In this embodiment, the first direction is perpendicular to the longitudinal axis direction of the styling body402. The linkage mechanism also includes an intermediate member406connecting the clipping member423and the swinging member404. The intermediate member406is configured in an L shape including a generally transverse first end portion461and a generally longitudinal second end portion462. The first end portion461is provided with a hole for a pivot shaft of the swinging member404to pass through. The second end portion462is fixedly connected with the clipping member423.

Specifically, two ends of the swinging member404are respectively provided with the pivot shafts, and the two pivot shafts face opposite directions along the longitudinal axis direction of the styling body402. The sliding member403is provided with a shaft hole for receiving the pivot shaft at one end of the swinging member404. The first end portion461of the intermediate member406is provided with a shaft hole for receiving the pivot shaft of the other end of the swinging member404. The second end portion462of the intermediate member406is fixedly connected with the clipping member423through a fixing member. In this embodiment, the fixing member includes a bolt and a nut matched with the bolt.

In the second embodiment, the styling body402also includes an outer shell421and an inner bracket422. Different from the first embodiment, the inner bracket422is a split type, and end portions of the inner bracket422are provided with protruding inserts.

A mounting sleeve409is also provided in the styling body402. The mounting sleeve409is provided with a mounting portion for receiving the inserts of the inner bracket422, and is also provided with a mounting hole for passing through the end of the clipping member423. In addition, the second end portion462of the intermediate member406is further provided with a limiting portion463abutting against the mounting sleeve409. By providing the mounting sleeve409, on one hand, it is beneficial to the stability of the entire set of transmission structure, and on the other hand, it also plays the role of restricting the swinging member404to transmit the movement in the first direction to the clipping member423.

Referring toFIG.33, the sliding member403is configured as a slider432. A sliding rail431is fixedly arranged in the styling body402. The slider432reciprocates in the sliding rail431.

A free end of the slider432protrudes beyond the styling body402so as to constitute an operation portion (not shown). In a non-triggered state, the hair clipping gap408is in a closed state, and the free end of the slider432protrudes beyond the sliding rail431. When the hair clipping gap408needs to be opened, the operation portion is pressed inwardly to move the slider432relative to the sliding rail431in the first direction. The swinging member404is pushed, and under a force that is restricted from moving in the first direction, the movement direction is changed to move the two clipping members423away from each other. As a result, the clipping gap408is opened, allowing the user to place hair into the clipping gap408.

Referring toFIG.33, the same as the first embodiment, the clipping member423includes a support plate424which is connected with the linkage mechanism.

The clipping member423further includes a floating clipping plate425disposed on a side of the support plate424close to the hair clipping gap408. A restoring member is provided between the floating clipping plate425and the support plate424. The elastic restoring force of the restoring member biases the floating clipping plate425toward the hair clipping gap408. Here, the restoring member is a spring407.

In summary, the hair curling device provided by the present application includes the hair clipping gap408and the clipping member423actuated by the mechanical transmission mechanism, so that the user can fix a section of the hair before curling the hair. Then, the hair is rotated around the outer shell421. Finally, the curling hair is shaped under the action of hot air. Such a structure is convenient for fixing the hair and avoids the failure of the curling due to the hair slipping during the styling process.

Referring toFIG.35toFIG.39, the present application provides a hair curling device, including: a handle501; a styling body502movably connected with the handle501, the styling body502including two half-shell assemblies521, and the half-shell assemblies521being provided with air outlet holes5210; and a transmission mechanism connected with at least one of the half-shell assemblies521, the transmission mechanism being operable to drive at least one of the half-shell assemblies521to translate relative to a remaining one of the half-shell assemblies521so as to form an openable and closable hair clipping gap.

The hair curling device realizes relative translation of the two half-shell assemblies521through a simple transmission mechanism, thereby forming the openable and closable hair clipping gap. It is convenient for the placement and clipping of the hair, and there is no need to worry about the styling failure caused by the hair slipping during the curling process.

The present application provides two preferred embodiments of the transmission mechanism. In these two preferred embodiments, both the half-shell assemblies521are connected to the transmission mechanism. That is, under the driving of the transmission mechanism, the two half-shell assemblies521move relatively close to each other or move away from each other at the same time. When moving away from each other, the hair clipping gap becomes larger until a maximum gap is reached, and the user places the hair to be styled into the hair clipping gap. When moving close to each other, the hair clipping gap becomes smaller until it is closed, and the hair to be styled is reliably clipped, so as to proceed to a next step of the styling process.

Of course, in other not-shown embodiments, only one half-shell assembly521may be connected to the transmission mechanism, and the other half-shell assembly521may be fixed relative to the handle501. In this way, when the transmission mechanism drives the one half-shell assembly521to translate relative to the handle501, the one half-shell assembly521also moves close to or moves away from the other half-shell assembly521, so that the hair clipping gap is closed or opened.

Wherein,FIG.35toFIG.38show a first embodiment, andFIG.39toFIG.42show a second embodiment, which will be described in sequence below.

Referring toFIG.36toFIG.38, the transmission mechanism includes a gear structure. The gear structure is provided between the handle5011and the half-shell assembly521. The gear structure translates the half-shell assembly521relative to the handle501by rotation.

Specifically, the gear structure includes a motor504, a gear503sleeved on the motor504, and a rack505meshing with the gear503. The rack505is disposed at the bottom of the half-shell assembly521. In this embodiment, the rack505and the half-shell assembly521are integrally formed. The rotation of the gear503drives the rack505to translate, so that the half-shell assembly521translates relative to the handle501.

Preferably, the gear503includes a driving wheel531and a driven wheel533intermeshing with the driving wheel531. The motor504includes an output shaft541. The driving wheel531is sleeved on the output shaft541. In this embodiment, a total of one driving wheel531and three driven wheels533are provided. The driving wheel531is driven by the motor504to drive the driven wheel533to rotate. By arranging the driving wheel531and the driven wheel533, and a row of racks505meshing with the driving wheel531and the driven wheel533are disposed on both sides of the bottom of each half-shell assembly521, thereby ensuring the stability of the translational movement of the half-shell assembly521.

Of course, in other embodiments, only one of the half-shell assemblies521may be provided with the racks505on both sides of the bottom, while the other half-shell assembly521remains stationary relative to the handle501. Accordingly, the gear503includes only one driving wheel531and only one driven wheel533. The driving wheel531is driven by the motor504to drive the driven wheel533to rotate. The driving wheel531and the driven wheel533are respectively matched with the racks505on the both sides of the bottom of the half-shell assembly521. Therefore, the motor504drives the driving wheel531to rotate, so that one half-shell assembly521moves close to or moves away from the other half-shell assembly521, thereby forming the openable and closable hair clipping gap.

Referring toFIG.37andFIG.38, the gear structure further includes a gear carrier535between the motor504and the gear503. The gear carrier535is provided with a plurality of protruding posts5351for mechanically connecting with the gears503, respectively. In this embodiment, both the driving wheel531and the driven wheel533are provided with shaft holes532. The gear carrier535is provided with four protruding posts5351. The driving wheel531and the driven wheel533are respectively sleeved on the corresponding protruding posts5351through the shaft holes532. The gear carrier535provides stable support for the driving wheel531and the driven wheel533, thereby ensuring the stability of the gear structure.

The gear carrier535in the gear structure is located in the handle501below a top plane of the handle501. However, the driving wheel531and the driven wheel533are raised above the top plane of the handle501. The motor504located in the handle501drives the driving wheel531to rotate, and the driving wheel531drives the driven wheel533to rotate. When the driving wheel531and the driven wheel533rotate, the racks505at the bottom of the two half-shell assemblies521are driven relatively close to each other or away from each other, thereby forming the openable and closable hair clipping gap.

Referring toFIG.36, an upper end of the handle501is provided with a sliding slot513. Two ends of the bottom of the half-shell assembly521are provided with protrusions211. The protrusions211are accommodated in the sliding slot513and are movable along the sliding slot513. The arrangement of the protrusions211and the sliding slot513facilitates the translational movement of the half-shell assembly521relative to the handle501.

Referring toFIG.39toFIG.42, in the second embodiment, the transmission mechanism includes a swinging rod structure. The swinging rod structure is arranged between the handle501and the half-shell assembly521. The swinging rod structure translates the half-shell assembly521relative to the handle501by rotating.

Specifically, the swinging rod structure includes a swinging rod506, a sliding rail507cooperating with the swinging rod506, and a pivot shaft563. The swinging rod506is rotatable about the pivot shaft563. In this embodiment, a pair of sliding rails507are provided. The two sliding rails507are respectively disposed at the bottom end of the half-shell assembly521. The swinging rod506is partially disposed in the handle501. The two sliding rails507are respectively connected with two ends of the swinging rod506. The pivot shaft563is disposed in the middle of the swinging rod506. When the swinging rod506rotates around the pivot shaft563, two ends of the swinging rod506push the two sliding rails507to translate. When the swinging rod506is substantially parallel to the sliding rails507, the two sliding rails507are close to each other. When the swinging rod506is rotated to a position perpendicular to the sliding rails507, the two sliding rails507are spaced apart from each other to a maximum distance.

The present embodiment shows a situation where the swinging rod structure causes the two half-shell assemblies521to translate relative to each other. Of course, in an alternative embodiment, one end of the swinging rod506may also be connected to the pivot shaft563, and the other end may be connected to the sliding rail507provided at the bottom end of one of the half-shell assemblies521. When the swinging rod506rotates around the pivot shaft563, the other end pushes the sliding rail507to translate, so that the half-shell assembly521moves close to or moves away from the other half-shell assembly521to form the openable and closable hair clipping gap.

Referring toFIG.41, two ends of the swinging rod506are provided with upwardly protruding sliders561, and the sliders561are movable in the sliding rails507.

In conjunction withFIG.39andFIG.41, the swinging rod structure further includes an operating rod565. One end of the operating rod565is connected with the swinging rod506through the pivot shaft563, and the other end extends out of the receiving groove5212of the handle501.

The user rotates the operating rod565to drive the swinging rod506to move in a circumferential direction, so that the swinging rod506pushes the two sliding rails507closer to each other or relatively away from each other through the sliders561at two ends, thereby realizing the opening and closing of the hair clipping gap.

Referring toFIG.40, an upper end of the handle501is provided with a sliding slot513. The bottom end of the half-shell assembly521is provided with a protrusion211. The protrusion211is accommodated in the sliding slot513and is movable along the sliding slot513. The arrangement of the protrusion211and the sliding slot513facilitates the translational movement of the half-shell assembly521relative to the handle501on the one hand, and limits the movement direction of the sliding rail507in the swinging rod structure on the other hand.

In summary, in the hair curling device provided in this application, since the styling body502includes the two half-shell assemblies521, through a simple and easy transmission mechanism, the openable and closable hair clipping gap is formed between the half-shell assemblies521, so that the user can fix a section of the hair before curling the hair. Then, the hair is rotated around the closed styling body502. Finally, the curling hair is shaped under the action of hot air, and the styling is completed under the action of cold air. Such a structure is convenient for fixing the hair and avoids the failure of the curling due to the hair slipping during the styling process.
