Description

Technical Field

[0001] The utility model relates to the technical field related to hair processing equipment, in particular to a hair curler. Background Art

[0002] In the relevant technical field, hair curlers usually use electric current to pass through heating elements to generate heat. After heating the hair to a certain temperature, the protein structure in the hair is temporarily changed to shape different hairstyles. The heating element can generally quickly heat up to the set temperature and maintain a relatively stable temperature range to ensure the consistency of the perm effect.

[0003] However, currently various types of hair curlers mainly focus on the perming function and have the following defects: on the one hand, among the few hair curlers equipped with a blow-drying function, the hot air is difficult to effectively dry the hair quickly, and most hair curlers do not have a blow-drying function. Therefore, users need to use a hair dryer to dry their hair in advance during use, which makes the equipment complicated and inconvenient to use; on the other hand, if the hair is repeatedly ironed to dry it only by relying on the perming function, the problem of uneven drying will occur, because it is difficult to keep a constant speed when manually controlling the speed of the hair curler, which will cause some hair to be over-heated and damaged, while some hair will be under-heated and still damp.

[0059] The present application will be further described in detail below through the accompanying drawings and examples, through which the features and advantages of the present application will become more clear and distinct.

[0060] The word "exemplary" is used exclusively herein to mean "serving as an example, example, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

[0061] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0062] In the related art, the current hair curlers have the following main defects: on the one hand, among the few hair curlers equipped with a blow-drying function, the hot air is difficult to effectively dry the hair quickly, and most hair curlers do not have a blow-drying function, so users need to use a hair dryer to dry their hair in advance during use, which makes the equipment complicated and inconvenient to use; on the other hand, if the hair is repeatedly ironed to dry it only by relying on the perming function, the problem of uneven drying will occur, because it is difficult to keep a constant speed of the hair curler on the hair by manual control, which will cause some hair to be over-heated and damaged, while some hair will be under-heated and still damp.

[0063] The present application provides a hair curler that optimizes its air outlet to form a special air duct structure corresponding to different air outlets, thereby enabling the hair curler to have two modes: a blower mode and a perm / blow-dry mode. When the user uses the blower mode, the upper and lower clamps do not heat up, and only the air duct blows out high-speed hot air for rapid hair drying. When the user uses the perm / blow-dry mode, the upper and lower clamps heat up while the air duct blows high-speed hot air toward the hair pressed by the clamps, straightening the hair while thoroughly drying it, providing high efficiency and convenience.

[0064] The technical solution of this embodiment is described in detail below with reference to the accompanying drawings. The following embodiments and implementation methods can be combined with each other unless there is any conflict.

[0065] In an exemplary embodiment of the present invention, a hair iron is provided. Figure 1 As shown, Figure 1 FIG1 is a schematic diagram showing a hair iron in a first working state according to an exemplary embodiment. The hair iron comprises a lower clamping plate assembly 10 and an upper clamping plate assembly 20 .

[0066] like Figures 1-4 、 Figure 7 As shown, the lower plate assembly 10 comprises a lower plate body and a lower heating element 102. An annular air duct is formed at the first end of the lower plate body. A lower air outlet 104 is formed in the middle region of the annular air duct, extending through the lower plate body. The annular air duct also includes an annular air outlet 103A, which opens toward the upper plate assembly 20. The lower heating element 102 is disposed on the side of the lower plate body facing the upper plate assembly 20 and surrounds the annular air outlet 103A. The annular air outlet 103A features a trumpet-like diffuser design, expanding the airflow range and reducing wind noise.

[0067] like Figures 1-4 、 Figure 11 As shown, the upper clamping plate assembly 20 includes: an upper clamping plate body, a middle area of ​​the first end of the upper clamping plate body is provided with an upper air outlet 201 that passes through the upper clamping plate body, the upper air outlet 201 corresponds to the annular air outlet 103A, and the second end of the upper clamping plate body is rotatably connected to the second end of the lower clamping plate body; an upper heating body 202, the upper heating body 202 is arranged on the side of the upper clamping plate body facing the lower clamping plate assembly 10, and is arranged around the upper air outlet 201, the upper heating body 202 corresponds to the lower heating body; and a damper assembly 30, which is arranged at the upper air outlet 201 and is used to open or close the upper air outlet 201.

[0068] In this embodiment, the second end of the lower clamping plate body is also integrated with a corresponding controller, a fan 60 and a corresponding electric heating element 50, etc., to cooperate with or control the operation of the upper and lower clamping plate assemblies 10. Figure 1-Figure 2 、 Figure 5 As shown, when the user is using the hair dryer 60 mode, neither the upper heating element 202 in the upper clamping plate assembly 20 nor the lower heating element 102 in the lower clamping plate assembly 10 generates heat. Only the air duct blows out high-speed hot air for quickly drying the hair. Specifically, the air delivered by the blower 60 is heated by the electric heating element 50, first enters the annular air duct, and then blows toward the upper clamping plate assembly 20 through the annular air outlet 103A. Since the damper assembly 30 is in an open state at the upper air outlet 201 of the upper clamping plate assembly 20, the hot air can be delivered through the upper air outlet 201, that is, the upper air outlet 201 of the upper clamping plate assembly 20 serves as the air outlet in the hair dryer 60 mode.

[0069] When the user uses the perm and blow-dry mode, the upper heating element 202 of the upper clamping plate assembly 20 and the lower heating element 102 of the lower clamping plate assembly 10 generate heat simultaneously. The blower 60 delivers an appropriate amount of air, which is then heated to a suitable temperature by the air supply heating assembly. The hot air is first delivered into the annular air duct and then blown through the annular air outlet 103A toward the hair held between the upper clamping plate assembly 20 and the lower clamping plate assembly 10. At this time, because the damper assembly 30 is closed at the upper air outlet 201 of the upper clamping plate assembly 20, the hot air is deflected and then delivered through the lower air outlet 104 corresponding to the upper air outlet 201. Thus, the lower air outlet 104 of the lower clamping plate assembly 10 serves as the air outlet in the perm and blow-dry mode. In this mode, the hair iron of this embodiment can blow high-speed hot air that fully contacts the hair, thereby straightening the hair while thoroughly drying it, making the perming and drying process efficient and convenient.

[0070] In some exemplary embodiments, considering that the air volume outputted from different air outlet points of the annular air outlet 103A is different, which will affect the blowing effect, the internal structure of the lower clamping plate body is optimized in this embodiment. Figure 7-10 As shown, the lower plate body includes: a lower plate shell 101, a lower plate air duct 103, and a flow guide 105. The lower plate shell 101 includes a lower plate bottom shell 1011 and a lower plate shell cover 1012. The lower plate air duct 103 is disposed within the lower plate shell 101 and is formed with an air inlet end, an air duct connecting section, and an air outlet end that are sequentially connected. The air inlet end of the lower plate air duct 103 is provided with a fan 60 and an electric heater 50, and the air outlet end of the lower plate air duct 103 forms an annular air duct. The flow guide 105 is disposed within the annular air duct and is used to evenly distribute the air volume directed to the annular air outlet 103A. By providing the guide member 105, the air supply pressure of each section inside the annular air duct can be adjusted and controlled. When the air is delivered through the annular air outlet 103A, the air output at each point of the annular air outlet 103A is more uniform, thereby improving the hair drying efficiency.

[0071] For example, Figure 10As shown, the air guide 105 is formed with a wedge-shaped air trough arranged around the circumference of the downwind outlet 104. The wedge-shaped air trough includes a first air guide section 105A, a second air guide section 105B, and a third air guide section 105C, which are connected in sequence. In this embodiment, the first air guide section 105A and the third air guide section 105C are respectively arranged on either side of the downwind outlet 104 along the direction from the air inlet end to the air outlet end. The second air guide section 105B is arranged on the side of the downwind outlet 104 facing away from the air inlet end. The slots of the first, second, and third air guide sections 105A, 105B, and 105C all face the annular air outlet 103A. In this embodiment, the wedge-shaped air trough is provided to adjust the air supply pressure of each section within the annular air duct, resulting in a more balanced air volume delivered through the annular air outlet 103A. This allows hair to dry quickly and prevents users from repeatedly ironing their hair to thoroughly dry it.

[0072] Further optionally, as Figure 10 As shown, the deflector 105 comprises a trough bottom plate, with a mounting opening 1053 in the middle region thereof for fitting onto the outer wall of the downwind outlet 104; an inner baffle 1051 disposed around the edge of the mounting opening 1053; and outer baffles 1052 disposed around three sides of the trough bottom plate, comprising a first side, a second side, and a third side connected in sequence. In this embodiment, the first side cooperates with the inner baffle 1051 to form a first deflector section 105A, the second side cooperates with the inner baffle 1051 to form a second deflector section 105B, and the third side cooperates with the inner baffle 1051 to form a third deflector section 105C. In this method, the inner baffle 1051 is arranged around the edge of the mounting hole to form an inner ring plate. On the one hand, it can cooperate with the outer baffle 1052 and the groove bottom plate to form the above-mentioned wedge-shaped wind groove. On the other hand, it can serve as a guide member for the lower air outlet 104, which facilitates the installation of the guide member 105 on the lower air outlet 104 and increases the stability of the guide member 105 in the lower splint body.

[0073] In order to achieve uniform air output at different air outlet points of the annular air outlet 103A, the grooves of the wedge-shaped air grooves can be evenly arranged. For example, along the direction from the air inlet end to the air outlet end, the groove depths of the first guide section 105A and the third guide section 105C are the same, and the groove widths of the first guide section 105A and the third guide section 105C gradually become smaller.

[0074] It should be noted that the depth and width of the wedge-shaped duct can be designed according to actual needs. When the depth of the wedge-shaped duct varies, the duct width needs to be adjusted accordingly. For example, if the duct depth becomes shallower, the duct width should be appropriately increased; otherwise, the duct width should be appropriately decreased.

[0075] In some exemplary embodiments, the flow area at the inlet of the air duct connecting section is larger than the flow area at the outlet of the air duct connecting section. By throttling the air supply, the air supply velocity is increased, thereby enhancing the hair drying effect. In this embodiment, the air guide 105 is embedded in the annular air duct of the lower clamping plate body. The air duct connecting section is located upstream of the air guide 105. The high-speed airflow is initially compressed by the air duct connecting section before entering the air guide 105. The annular air outlet 103A is formed on the inner ring of the lower clamping plate body and is located directly above the air guide 105. The high-speed airflow passes through the air duct connecting section and the air guide 105 in sequence, and then is ejected upward through the annular air outlet 103A.

[0076] Optionally, the air duct connection section can be designed as a circle, and the connection between it and the annular air duct can be deformed, that is, gradually flattened and the flow cross-sectional area is reduced to form a duckbill-shaped convergent flow channel. Figure 5-Figure 6 、 Figure 9 As shown, the duct structure of the duct connecting section is a convergent type, and the cross-section of the cylindrical high-speed airflow on the air inlet side becomes smaller after flowing through the duct connecting section, and the flow rate is further improved; the duct on the air outlet side of the duct connecting section is narrow, and the duct on the air inlet side is wider. In conjunction with the air outlet end of the lower splint duct 103, a guide member 105 is installed, so that the high-speed airflow is blocked in advance when entering the annular air duct from the duct connecting section to form a high-pressure area, thereby moving the high-pressure area formed by the high-speed airflow to the duct connecting section, and the high-pressure area is evenly distributed in the middle section of the duct, effectively utilizing the air outlet area of ​​the duct, and ensuring that the air outlet of the annular air outlet 103A is relatively uniform.

[0077] In some exemplary embodiments, Figure 8-Figure 9 As shown, the lower splint air duct 103 includes: an air duct bottom shell 1031, on which a lower air outlet 104 is provided; an air duct upper cover 1032, which is detachably connected to the air duct bottom shell 1031, wherein a lower heating body 102 is provided on the side of the air duct upper cover 1032 facing away from the air duct bottom shell 1031.

[0078] Optionally, the hair curler further includes a housing assembly. The housing assembly comprises an upper plate housing and a lower plate housing 101, which respectively cover the outer surfaces of the lower plate assembly 10 and the upper plate assembly 20. The assembly of the air duct bottom housing 1031 and the air duct upper cover 1032 forms an independent air duct and a heat-insulated design for the lower plate housing 101, effectively protecting the user from burns.

[0079] In some exemplary embodiments, Figure 5-Figure 6 As shown, the damper assembly 30 includes: a rotating shaft 302, the first end of which is rotatably arranged on the upper clamping plate body; an air guide plate 301, which is arranged at the second end of the rotating shaft 302 and is used to open and close the upper air outlet 201; and a switch assembly 303, which is used to control the opening and closing of the damper assembly 30.

[0080] Alternatively, as Figure 4 As shown, a sealing strip 2011 is provided on the inner side of the upper air vent 201 for cooperating with the damper assembly 30 to seal the upper air vent 201. The design of the sealing strip 2011 can not only ensure the sealing effect of the upper air vent 201 after the air guide plate 301 is closed, but also cooperate with the switch assembly 303 to limit the position of the air guide plate 301 when it is in the closed state.

[0081] In some exemplary embodiments, to achieve adjustment and control of the air guide plate 301 , a cam 3021 with a cam groove 30211 may be provided on the rotating shaft 302 , and a guide column 30321 may be provided on the switch assembly 303 to cooperate with the cam groove 30211 .

[0082] For example, Figure 5-Figure 6 As shown, a cam 3021 is formed on the circumference of the rotating shaft 302, and a cam slot 30211 is defined on the cam 3021. The switch assembly 303 includes a push plate 3032 and a switch 3031. The push plate 3032 is slidably disposed on the upper clamping plate body and is provided with a guide post 30321, the free end of which extends into the cam slot 30211. The switch 3031 is connected to the push plate 3032, and the switch 3031 can push the push plate 3032 to slide, thereby cooperating with the rotating shaft 302 through the guide post 30321 to open and close the air deflector 301.

[0083] Specifically, such as Figure 5-Figure 6 As shown, a cam groove 30211 is provided on the cam 3021, and a guide column 30321 is provided at the bottom of the push plate 3032. The guide column 30321 slides in the cam groove 30211. The rotating shaft 302 with the cam 3021 is installed in the upper clamping plate body, and the rotating shaft 302 can only rotate in the upper clamping plate body. The rotating shaft 302 is rigidly connected to the air guide plate 301. Due to the engagement of the cam groove 30211 and the guide column 30321, the forward and backward movement of the push plate 3032 will drive the rotating shaft 302 and the air guide plate 301 to rotate.

[0084] In some exemplary embodiments, when using the blowing mode, the upper clamping plate assembly 20 and the lower clamping plate assembly 10 need to be locked together so that the upper air outlet 201 corresponds to the annular air outlet 103A to facilitate blowing. For example, a locking tongue 30322 is provided on the push plate 3032, and a lock 106 is provided on the lower clamping plate body. The hair iron has a first operating state and a second operating state. The first operating state includes: the locking tongue 30322 engages with the lock 106 to lock the upper clamping plate assembly 20 and the lower clamping plate assembly 10, while the damper assembly 30 opens the upper air outlet 201. The second operating state includes: the locking tongue 30322 disengages from the lock 106 to open the upper clamping plate assembly 20 and the lower clamping plate assembly 10, while the damper assembly 30 closes the upper air outlet 201.

[0085] Specifically, such as Figure 7-Figure 8 As shown, the lower plate body is provided with a lower plate air duct 103 and an annular air outlet 103A, and the lower plate body is also provided with a lock 106. The upper plate body is provided with a damper assembly 30, wherein the damper assembly 30 includes an air guide plate 301. The air guide plate 301 can reciprocate within 0° to 90° within the upper air outlet 201, and the rotation can be controlled by a switch assembly 303. The rotating shaft 302 in the switch assembly 303 is provided with a cam 3021 with a cam groove 30211, which cooperates with the guide post 30321 on the push plate 3032. At the same time, the push plate 3032 is designed with a lock tongue 30322 at the bottom, which cooperates with the lock 106. In addition, heating bodies (upper heating body 202 and lower heating body 102) are installed on both the lower plate body and the upper plate body, and the two heating bodies are placed opposite each other.

[0086] like Figure 1 、 Figure 4-Figure 6 As shown, when the lock tongue 30322 is engaged with the lock buckle 106, the lower clamping plate assembly 10 and the upper clamping plate assembly 20 are combined into one, and the air guide plate 301 rotates 90° to an upright state, that is, the upper air outlet 201 is opened, and high-speed hot air is ejected from the annular air outlet 103A. This mode is the hair dryer 60 mode.

[0087] like Figure 2 As shown, when the lock tongue 30322 is disengaged from the lock buckle 106, the air guide plate 301 is in a horizontal state, and the upper clamping plate body rotates within a certain angle on the lower clamping plate body through the connecting shaft 40, which is reflected in the opening and closing action of the lower clamping plate body and the upper clamping plate body. At this time, the upper heating body 202 and the lower heating body 102 start to work, and the user can put the hair into the two heating bodies for ironing. At the same time, part of the high-speed and high-temperature airflow is blocked by the hair and discharged downward. After part of the airflow blows through the hair, it is hindered by the air guide plate 301, forming a high-pressure area between the air guide plate 301 and the hair and finally discharged downward through the lower air outlet 104. In this process, the hair is not only ironed by the two heating bodies, but also affected by the high-speed and high-temperature airflow blown out by the annular air outlet 103A, so that the hair can be dried at an extremely fast rate, and the ironing is completed in one go, and the user experience is better.

[0088] like Figure 12 、 13As shown, a micro switch 70 is provided in the upper clamping plate body, and the hair curler also includes a control unit (not shown in the figure). The micro switch 70 is electrically connected to the control unit, and a triggering part 30323 for triggering the micro switch 70 is provided on the push plate 3032. When the hair curler is in the first working state, the triggering part 30323 triggers the micro switch 70, and the control unit controls the upper heating body 202 and the lower heating body 102 not to work; when the hair curler is in the second working state, the triggering part 30323 disengages from the micro switch 70, and the control unit controls the upper heating body 202 and / or the lower heating body 102 to work.
