Description

Technical Field

[0001] This invention relates to the field of hair styling equipment technology, and in particular to a hair straightener and its styling method. Background Technology

[0002] In daily life, hair straighteners are often used to straighten hair to achieve a beautiful hair effect. Most traditional hair straighteners simply use heating plates to clamp and heat the hair to straighten it. A few hair straighteners also have a blower function to dry the hair while straightening it.

[0003] These hair straighteners are basically designed to work together as a straightener and a blow dryer, and cannot be used as a standalone straightener or a blow dryer. Their functions are relatively limited and cannot meet the needs of consumers. Summary of the Invention

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a hair straightener nozzle that solves the problem of the limited functionality of existing hair straighteners.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hair straightener nozzle, comprising:

[0007] The straightening unit includes two arms that are hinged to each other at one end, and each arm has two straightening plates facing each other on its styling surface;

[0008] The air duct unit includes an air supply duct on one arm and an airflow channel on the other arm. The airflow channel is opposite to the air outlet of the air supply duct and guides the airflow out. The air outlet of the air supply duct is located on the side of the two straightener plates.

[0009] A control unit, located on either arm, controls the straightening unit and the blower unit to work individually or together, entering straightening mode, blow-drying mode, or straightening and blow-drying mode.

[0010] As a preferred embodiment, the air supply duct has an air inlet and an air outlet, and a motor and a first heating element are installed inside the air supply duct. The airflow passes through the air inlet, the motor, and the heating element and is blown out from the air outlet.

[0011] As a preferred embodiment, the air inlet is located at the handle of the hair straightener, and the air outlet is located in the middle of the styling surface of the arm with the air delivery duct, and is located between the two straightener plates.

[0012] As a preferred option, the arm with an air supply duct has a dual-function channel for low-pressure airflow and drainage on its shaped surface.

[0013] As a preferred embodiment, the dual-function channel has a water inlet and a drain outlet, with the water inlet located between the air outlet and the corresponding straightener plate, and the drain outlet located on the back of the arm.

[0014] As a preferred embodiment, the hair straightener plate has a second heating element.

[0015] As a preferred embodiment, it also includes a locking mechanism for limiting the opening of the two arms, the locking mechanism being located on either arm.

[0016] As a preferred embodiment, the system also includes a display unit located on either arm.

[0017] A styling method for a hair straightener, based on the hair straightener described above, enters one of the following styling modes: (1) straightening mode; (2) cold air blowing mode; (3) hot air blowing mode; (4) straightening + hot air blowing mode; (5) straightening + cold air blowing mode.

[0018] As a preferred option, (1) in the direct heating mode: only the second heating element of the direct heating plate works, and the motor and the first heating element do not work.

[0019] (2) When blowing cold air mode: only the motor works, the first heating element and the second heating element do not work to blow out natural air;

[0020] (3) When blowing hot air: only the motor and the first heating element work together, and the second heating element does not work;

[0021] (4) When using the direct hair + cold air blowing mode: only the motor and the second heating element work together, and the first heating element does not work;

[0022] (5) When in the direct heat + hot air mode: the first heating element, the motor and the second heating element work together.

[0023] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, the straightening unit and the blower unit can be controlled individually or together by the control unit, and can be switched at will in straightening mode, blow-drying mode or straightening and blow-drying mode. This allows the product to be used alone as a straightener, as a blower, or as a straightener and blower. It has diversified functions and is easy to use, which is very popular among consumers.

[0024] The product of this application has a straightening mode, a hot air blowing mode, a cold air blowing mode, a straightening + cold air blowing mode, and a straightening + hot air blowing mode, with diversified functions. Consumers can choose or switch between different modes to style their hair according to their needs.

[0025] By providing an air supply duct within one arm and an airflow channel on the styling surface, the airflow channel guides the airflow delivered by the air supply duct (i.e., forms a direct blow), effectively preventing airflow turbulence and minimizing reduction in airflow velocity and airflow volume, thereby shortening styling time and improving styling efficiency. At the same time, after the airflow is guided, it effectively prevents the airflow from blowing onto the straightener and affecting the heat of the straightening unit.

[0026] To more clearly illustrate the structural features and effects of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

Therefore, they should not be construed as limitations on this application.

[0054] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0055] Please see Figures 1 to 8As shown, this application provides a hair straightener, which is an integrated handheld device that can be used to quickly dry hair and straighten it.

[0056] A hair straightener includes a straightening unit, a blower unit, and a control unit 30. The straightening unit is equivalent to a hair straightener and is used to straighten hair. The blower unit is equivalent to a hairdryer and is used to dry hair. The control unit 30 is used to control the straightening unit and the blower unit to work together or independently, thereby switching between different styling modes.

[0057] The straightening unit includes two arms 11 that are hinged to each other at one end. Each of the two arms has two straightening plates 12 facing each other on its styling surface 101. The straightening plates 12 are used to heat and straighten the hair.

[0058] The air duct unit includes an air supply duct 21 located on one arm and an airflow channel 22 on the other arm. The airflow channel is opposite to the air outlet of the air supply duct and guides the airflow out. The air outlet of the air supply duct 21 is located on the side of the two straightener plates 12.

[0059] The control unit 30 is located on any arm 11. The control unit 30 controls the straightening unit and the blower unit to work individually or together, entering the straightening mode, blow-drying mode or straightening and blow-drying mode. Thus, this product can switch freely between multiple usage modes, has diversified functions, and is easy to use, making it popular with consumers.

[0060] In straightening mode, the consumer holds a section of wet hair between two opposing straightening plates 12 and pulls the device along the direction of hair growth. The two pairs of straightening plates 12 scrape the wet hair, removing excess unbound water and heating the hair to accelerate subsequent evaporation. During the pulling process, the two pairs of straightening plates 12 also straighten the hair for styling.

[0061] In blow-drying mode, the air outlet 215 of the air supply duct 21 delivers airflow, and the consumer directs the airflow channel 22 toward the hair, and the blown air dries the hair.

[0062] In the hair straightening and drying mode, wet hair is clamped between the styling surfaces 101, and the device is pulled along the direction of hair extension. The two pairs of straightening plates 12 straighten the hair, and simultaneously, the blower unit dries the hair, completing the straightening and drying of the hair.

[0063] More specifically, such as Figure 1 As shown, in one embodiment, the two arms 11 are a first arm 111 and a second arm 112, with one end of the first arm 111 and the second arm 112 hinged to each other, so that the first arm 111 and the second arm 112 cooperate to make the shaping surface 101 have a closed state (see...). Figure 1 ) and open state (see Figure 2 ).

[0064] like Figure 1 and Figure 2 As shown, one usage method is as follows: when the styling surfaces 101 of the first arm 111 and the second arm 112 are closed and clamp the hair, the straightening unit is activated, and the straightening plate 12 can straighten the hair. A second usage method is as follows: when the styling surfaces 101 of the first arm 111 and the second arm 112 are closed, the air dryer unit is activated, and the hair can be dried by bringing the device close to the hair. A third usage method is as follows: when open, wet hair can be collected between the first arm 111 and the second arm 112.

[0065] like Figure 1 As shown, multiple buttons 70 are provided on the outer wall of one of its arms 11. The multiple buttons 70 include a power switch button, a speed control button, and buttons for different modes.

[0066] like Figure 1 and Figure 2 As shown, a display unit 80 is also provided on the outer wall of any arm 11. The display unit 80 provides styling information, such as the current mode, as needed. In another embodiment, the hair straightener may also be equipped with a temperature detection unit, a humidity detection unit, etc., and their status can also be fed back to the display unit 80 as needed, so that the user can grasp the situation immediately and adjust the styling method or strategy in real time.

[0067] like Figure 2 As shown, in one embodiment of this application, the hair straightener's nozzle further includes a locking unit 90 for restricting the opening of the two arms. The locking unit 90 is disposed on either arm. In the closed state, the locking unit 90 can lock the two arms 11 together without requiring manual pressing of the two arms 11. The locking unit 90 includes: a hook groove 91 disposed on one arm 11 and a push button 92 disposed on the other arm 11. The push button 92 is provided with a locking hook. After the push button 92 is pushed into place, the locking hook locks with the hook groove 91.

[0068] like Figure 3 As shown, two straightening plates 12 are spaced apart on the styling surfaces 101 of the two arms 11. Each straightening plate has a second heating element, which conducts heat to the straightening plate 12 during straightening. Furthermore, since there are two straightening plates 12 on each styling surface, the heating and straightening effect is better and styling efficiency is improved compared to a single straightening plate. Additionally, the air outlet 215 of the air duct 21 and the airflow channel 22 are located between the spaced-apart straightening plates 12, making efficient use of space and reducing the size of the device. Optionally, the straightening plate 12 can be an aluminum plate or a ceramic float plate with a spring. This spring has a low rebound rate or low stiffness, thus providing good control over hair tension.

[0069] like Figures 4 to 6As shown, in one embodiment, the air duct 21 has an air inlet and an air outlet 215. The air inlet is located at the handle of the hair straightener, and the air outlet 215 is located in the middle of the styling surface of the arm with the air duct and between the two straightener plates 12. A motor 212 and a first heating element 213 are installed inside the air duct. Airflow passes from the air inlet through the motor 212 and the heating element 213 and exits through the air outlet 215. The air duct 21 also includes a hair dryer housing 211 disposed in one of its arms 11, and the motor 212 is built into the hair dryer housing 211. When the control unit 30 only controls the motor 212 to operate, it enters the cool air blowing mode. This can be understood as a type of blow-drying mode; in this mode, the airflow dries the hair or cools hot hair with cool air.

[0070] like Figure 5 As shown, optionally, the motor 212 includes a motor 201 and an impeller 202 disposed on the output shaft of the motor 201. The motor 201 drives the impeller 202 to rotate, and the airflow enters the air supply channel 211 through the air inlet 214 and is discharged through the air outlet 215.

[0071] Alternatively, motor 201 can be a brushless motor designed to operate at high speed (e.g., more than 30,000 revolutions per minute) and low power (e.g., 15W at maximum, 3W during normal operation) and can be driven by a DC power supply. These high-speed, low-power parameters provide excellent drying performance, drying hair as quickly as a conventional 2000W hair dryer, but with significantly reduced power consumption.

[0072] like Figure 5 and Figure 6 As shown, in one embodiment, the first heating element 213 is disposed inside the air duct housing 211 of the air supply duct 21 and is used to heat the airflow. When the control unit 30 controls the first heating element 213 and the motor 212 to work together, the hot air blowing mode is entered. It can be understood that the hot air blowing mode is another mode of the blow-drying mode. In the hot air blowing mode, hot air dries the hair, speeding up the drying efficiency of wet hair.

[0073] Optionally, the first heating element 213 is an electric heating coil or other heating element. The first heating element 213 and the second heating element in the straightener plate 12 are two separate heating systems of this device, which do not affect each other. One of them can work alone or together.

[0074] like Figure 5 and Figure 6As shown, in one embodiment, a guide structure 40 for changing the airflow direction is provided at the connection between the airflow channel 22 and the air supply duct 21. The guide structure 40 changes the airflow direction in the air supply duct 21 so that the airflow is blown out of the airflow channel 22.

[0075] like Figure 6 As shown, in one embodiment, the air guiding structure 40 includes a base frame 41 and a plurality of air guiding vanes 42 inclinedly disposed on the base frame 41. The base frame 41 is installed in the air supply channel 211. The plurality of air guiding vanes 42 are arranged at intervals along the airflow path, and the inclination angle of the plurality of air guiding vanes 42 gradually decreases along the airflow path.

[0076] The inclined air guide vanes 42 facilitate the guidance of airflow from the air outlet 215 outwards, ensuring even distribution of airflow and maintaining the desired styling effect. Secondly, because the airflow is larger at the front and gradually decreases at the rear, the inclination angle of the front air guide vanes 42 is designed to be larger than that of the rear air guide vanes 42. This ensures that the larger airflow at the front is evenly distributed, while the smaller airflow at the rear is directed outwards, guaranteeing sufficient airflow to the hair at the rear for optimal styling. Preferably, the inclination angle of the foremost air guide vane 42 is 45°, and the inclination angle of the rearmost air guide vane 42 is 90°.

[0077] like Figure 5 As shown, in one embodiment of this application, the arm 11 with the duct housing 211 includes: a lower shell 13 and an upper shell 14. The upper shell 14 and the lower shell 13 are spliced ​​together to form the air supply channel 211. A sealing strip 15 is sandwiched between the lower shell 13 and the upper shell 14 for the air outlet 215 end. The sealing strip 15 prevents airflow from leaking from the connection between the lower shell 13 and the upper shell 14. Preferably, the sealing strip 15 is a silicone strip.

[0078] like Figure 6 As shown, optionally, the control unit 30 is a PCB board, which is located in the air supply duct 215. The airflow in the air supply duct 215 can effectively remove the heat from the PCB board and improve the service life of the PCB.

[0079] In one embodiment, the control unit 30 controls the motor 212 and the straightener 12 to work together to enter a straightening + cool air blowing mode. This can be understood as a type of hair straightening and blow-drying mode; for example, during the straightening process, the cool air mode rapidly cools the hair, providing better hair care.

[0080] In one embodiment, the control unit 30 controls the first heating element 213, the motor 212, and the second heating element in the straightener 12 to work together to enter a straightening + hot air blowing mode. This can be understood as another mode of the straightening and hot air blowing mode. In this mode, one pair of straighteners 12 clamps and heats hair relatively close to the upper end, while another pair clamps and heats hair relatively close to the lower end. The airflow channel 22 guides the airflow to dry hair relatively in the middle. During the straightening process, the airflow channel 22 continues to dry the hair heated by one pair of straighteners 12, while the other pair of straighteners 121 reheats the hair blown by the airflow channel 22. This results in a first heating and straightening + drying + second heating and straightening process. Furthermore, the heat generated by the straighteners 12 and the blower unit quickly removes moisture from wet hair, thus shortening styling time and improving styling efficiency.

[0081] like Figure 7 and Figure 8 As shown, in one embodiment, the airflow channel 22 passes through one arm 11 and connects to the air outlet 215 of the air supply duct 21. The airflow channel 22 is opposite to the air outlet 215 and guides the airflow out. The air outlet 215 is located between the two corresponding straightener plates 12. The airflow channel 22 is located between the two corresponding straightener plates 12. The airflow channel 22 guides the airflow blown out of the air outlet 215, effectively preventing airflow turbulence, so that it will not affect the airflow speed and volume.

[0082] In one embodiment of this application, the straightener 12 on one arm 11 is arranged at a certain distance from the air outlet 215, and the straightener 12 on one arm 11 is arranged at a certain distance from the airflow channel 22. After the airflow is guided, it effectively prevents the airflow from blowing onto the straightener 12 and affecting the heat of the straightener 12.

[0083] In the straight hair + hot air blow-drying mode or the straight hair + cold air blow-drying mode, the straightening plates 12 on both arms 11 clamp the hair 1 to straighten it. At the same time, the air outlet 215 guides the high-speed airflow through the hair 1 located in the airflow channel 22 and blows it out directly from the airflow channel 22, so that the airflow dries the wet hair, thereby shortening the styling time and improving the styling efficiency.

[0084] When blowing hot or cold air, the styling surface 101 is closed. At this time, the air outlet 215 and the airflow channel 22 are close to each other. The airflow channel 22 guides the airflow blown out of the air outlet 215. When the consumer holds the device and brings the outside of the airflow channel 22 close to the hair, the airflow blows from the airflow channel 22 onto the hair to dry it.

[0085] like Figure 1 , Figure 2 , Figure 7 and Figure 8 In one embodiment, the airflow channel 22 is a hollow hole that runs straight through the corresponding arm 11. Multiple air outlets 215 are spaced apart and arranged in two rows on the molding surface 101 of the corresponding arm 11, with the two rows of air outlets 215 directly opposite the hollow hole. By designing the hollow hole as a large-diameter strip-shaped hole, the obstruction during airflow is reduced, ensuring smooth airflow. Designing multiple air outlets 215, each with a small diameter, increases the airflow speed as it travels from the front end (large diameter) of the air supply channel 211 to the end air outlet 215, further shortening the molding time and improving molding efficiency. The two rows of air outlets increase the airflow coverage area and improve airflow uniformity, further enhancing molding efficiency.

[0086] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, in one embodiment, the arm 11 with air supply duct 21 has a low-pressure airflow and drainage dual-function channel 50 on its shaped surface. The dual-function channel 50 has a drainage function and provides space for low-speed airflow acceleration. The dual-function channel 50 is directly opposite the airflow channel 22.

[0087] During the straightening process, the damp hair is scraped by the moving straightener 12, and the scraped liquid falls into the dual-function channel 50 and is then discharged through the dual-function channel 50, thus preventing the liquid from falling into the air outlet 215 and affecting the internal components of the hair dryer housing 211. At the same time, the design of the dual-function channel 50 increases the distance between the air outlet 215 and the straightener 12, effectively preventing high-speed airflow from blowing onto the straightener 12 and affecting the heat of the straightener 12.

[0088] In one embodiment of this application, the height of the hair straightener 12's clamping surface is higher than the height of the water inlet of the dual-function channel 50, thereby ensuring that the water scraped out by the straightener 12 can fall smoothly into the dual-function channel 50.

[0089] Figure 7 and Figure 8 As shown, optionally, there are two dual-function channels 50, which are located on the sides of the corresponding two straighteners 12. One dual-function channel 50 is used to collect the water scraped out by the first pair of straighteners 12, and the other dual-function channel 50 is used to collect the water scraped out by the second pair of straighteners 12.

[0090] like Figure 7 and Figure 8As shown, in one embodiment of this application, the dual-function channel 50 includes a water inlet 51 and a drain outlet 52. The water inlet 51 is recessed downward on the inner side of the shaping surface 101 of the first arm 111 and is located beside the air outlet 215, more specifically, between the air outlet and the corresponding straightener plate. The drain outlet 52 is recessed downward on the bottom wall of the water inlet 51 and penetrates the first arm 111, that is, the drain outlet 52 is located on the back of the arm 111. Exemplarily, the diameter of the water inlet 51 is larger than the diameter of the drain outlet 52, that is, the water inlet 51 is a large-diameter space to facilitate water collection, and the drain outlet 52 is a small-diameter hole for water drainage.

[0091] like Figure 7 As shown in one embodiment of this application, a plurality of meshes 53 are spaced apart at the upper opening of the water inlet 51. The meshes 53 effectively reduce the entry of hair and impurities into the water inlet 51. The end face of the meshes 53 facing the airflow channel 22 has an inclined surface to facilitate the flow of liquid into the dual-function channel.

[0092] like Figure 8 As shown, in one embodiment of this application, the back of the first arm 111 is an arc-shaped structure, and there are multiple drain outlets 52, which are spaced apart in the middle area of ​​the arc-shaped structure. By designing the back of the first arm 111 as an arc-shaped structure and having multiple drain outlets 52 concentrated in the middle area of ​​the arc-shaped structure, it is easier to guide and drain water.

[0093] like Figures 2-7 As shown, in one embodiment of this application, the upper opening edges of the two rows of air outlets 215 are jointly surrounded by a retaining rib 60, which can prevent moisture from seeping into the air supply channel 211 along the air outlets 215. Figure 8 As shown, the two rows of air outlets 215 form a line L connecting them to the corresponding edges of the surrounding rib 60. The two lines L extend to the inner wall of the airflow channel 22, forming a high-pressure zone A1 within the airflow channel 22. The area within the airflow channel 22 excluding the high-pressure zone A1, together with the dual-function channel 12, forms a low-pressure zone A2. The high-speed airflow in the high-pressure zone A1 increases the airflow volume and velocity in the low-pressure zone A2. The accelerated airflow in the low-pressure zone A2 flows towards the airflow channel 22, further drying the wet hair. In addition to its drainage function, the dual-function channel 12 provides space for airflow in the low-pressure zone A2, increasing the airflow time and thus accelerating the airflow velocity.

[0094] In one embodiment of this application, both pairs of straightener plates 12 are located on the side of the low-pressure zone A2. The high-speed airflow in the high-pressure zone A1 will not blow onto the straightener plates 12 on the side of the low-pressure zone A2, thereby effectively avoiding the problem of high-speed airflow affecting the heat of the straightener plates 12.

[0095] Based on the above-mentioned hair straightener, the present invention provides a hair straightener styling method, wherein the control unit 30 controls the hair straightening unit and the hair straightener unit to work individually or together, and enters a hair straightening mode, a blow-drying mode or a hair straightening and blow-drying mode.

[0096] In the blowing mode, the control unit 30 controls the blower unit to work and the straightening unit to not work. There are two blowing modes: the first is the cold air blowing mode and the second is the hot air blowing mode.

[0097] In the hair straightening and blow-drying mode, the control unit 30 controls the blower unit to work together with the hair straightening unit. There are two types of hair straightening and blow-drying modes: the first is hair straightening + cold air blowing mode, and the second is hair straightening + hot air blowing mode.

[0098] In summary, there are five modes: (1) straight hair mode; (2) cool air mode; (3) hot air mode; (4) straight hair + hot air mode; (5) straight hair + cool air mode.

[0099] In each mode, the operating status of the second heating element, motor 212, and first heating element 213 of the straightener plate 12 by the control unit 30 is as follows:

[0100] (1) In direct mode: only the second heating element of the direct heating plate (12) works, and the motor and the first heating element do not work.

[0101] (2) When blowing cold air mode: only the motor (212) works, the first heating element (213) and the second heating element do not work to blow out natural air;

[0102] (3) When blowing hot air: only the motor (212) and the first heating element (213) work together, and the second heating element does not work;
