Please refer to FIGS. 1 to 8, as shown in the present application, which provides a hair straightener air duct. The hair straightener air duct is an integrated handheld device that can be used to quickly dry hair while also straightening hair.

The straightener air duct includes a hair straightening unit, an air duct unit, and a control unit 30. The hair straightening unit is equivalent to a hair straightener, configured to straighten hair. The air duct unit is equivalent to a hair dryer, configured to blow hair. The control unit 30 is configured to control a joint or independent operation of the hair straightening unit and the air duct unit, thereby switching different styling modes.

The hair straightening unit includes two arms 11 that are hinged with each other at one end of the arm. Styling surfaces 101 of both arms are provided with two opposite straightening plates 12, which heat and straighten hair.

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

The control unit 30, provided on any one arm 11, controls the hair straightening unit and the air duct unit to work alone or together, and thereby entering a straightening hair mode, a blowing mode, or straightening hair and blowing mode, so that this product can switch freely among multiple use modes, with diverse functions and simple use, and is loved by consumers.

In the straightening hair mode, a consumer clamps a section of wet hair between two opposite straightening plates 12 and pulls the device along a direction of hair extension. Two pairs of straightening plates 12 cause the wet hair to be scraped, removing excess unbound moisture, and heating the hair to accelerate a subsequent evaporation of water. During a pulling process, the two pairs of straightening plates 12 also straighten the hair for styling purposes.

In the blowing mode, the air outlet 215 of the air supply duct 21 delivers airflow, and the consumer aligns the airflow channel 22 with the hair, allowing a blown airflow to dry the hair.

In the straightening hair and blowing mode, wet hair is sandwiched between the styling surface 101, and the device is pulled along the direction of the hair extension. Two pairs of straightening plates 12 straighten the hair, and synchronously, the air duct unit dries the hair 1, completing the straightening and drying of the hair.

More specifically, as shown in FIG. 1, in one embodiment, the two arms 11 are a first arm 111 and a second arm 112, respectively. One end of the first arm 111 and the second arm 112 are hinged with each other, so that the first arm 111 and the second arm 112 cooperate, providing the styling surface 101 with a closed state (see FIG. 1) and an open state (see FIG. 2).

As shown in FIGS. 1 and 2, one use mode is: when the styling surfaces 101 of the first arm 111 and the second arm 112 close and clamp the hair, the hair straightening unit is activated, and the straightening plate 12 can straighten the hair. A second use mode is: when the styling surfaces 101 of the first arm 111 and the second arm 112 are closed, the air duct unit is started to work, and the device is placed close to the hair to dry hair. A third use mode is to store wet hair between the first arm 111 and the second arm 112 when in an open state.

As shown in FIG. 1, multiple buttons 70 are provided on an outer wall of one arm 11, including a switch button, a speed control button, and different mode buttons.

As shown in FIGS. 1 and 2, a display unit 80 is also provided on an outer wall of any one arm 11, which provides feedback style information according to a demand, such as a current mode. In other embodiments, the hair straightener air duct may further be provided with a temperature detection unit, a humidity detection unit, etc., and the situation can also be feedback to the display unit 80, so that a user can grasp a situation in a timely manner and adjust the styling method or strategy in real-time.

As shown in FIG. 2, in one embodiment of the present application, the hair straightener air duct further includes a locking unit 90 for limiting an opening of the two arms. The locking unit 90 is located on any one arm, when in a closed state, the locking unit 90 can lock the two arms 11 together without manually pressing them down. The locking unit 90 includes a hook groove 91 located on one arm 11 and a push button 92 located on the other arm 11. The push button 92 is provided with a locking hook, and after the push button 92 is pushed into place, the locking hook is locked with the hook groove 91.

As shown in FIG. 3, there are two straightening plates 12 spaced on the styling surface 101 of the two arms 11. The straightening plates have a second heating element on them, which conducts heat to the straightening plate 12 when straightening hair. Furthermore, due to the fact that there are two straightening plates on each styling surface, compared to traditional single straightening plate, the heating effect when straightening hair is better, and the styling efficiency is improved. An air outlet 215 of the air supply duct 21 and an airflow channel 22 are placed between left and right straightening plates 12 arranged at intervals, rendering reasonable use of space, and reducing the volume of the device. In an implementation mode, the straightening plate 12 is an aluminum plate, or a ceramic float plate with a spring that has low rebound rate or stiffness, providing a good control over hair tension.

As shown in FIGS. 4 to 6, in one embodiment, the air supply duct 21 has an air inlet and an air outlet 215. The air inlet is located at a handle of the hair straightening air duct, and the air outlet 215 is located in a middle of the styling surface of the arm with the air supply duct and between the two straightening plates 12. The air supply duct is provided with a motor 212 and a first heating element 213, and the airflow is blown out from the air inlet 214 through the motor 212 and the heating element 213. The air supply duct 21 further includes an air duct housing 211 located in one arm 11, a motor 212 is built in the air duct housing 211. When the control unit 30 only controls an operation of the motor 212, it enters a blowing cold air mode. It can be understood that the blowing cold air mode is one of blowing modes. When entering the blowing cold air mode, the airflow dries the hair or blows cold air to cool hot hair.

As shown in FIG. 5, in an implementation mode, the motor 212 includes an impeller 202 located on an output shaft of the motor 211. The motor 221 drives the impeller 202 to rotate, and the airflow enters the airflow channel 22 through the air inlet 214 and is discharged through the air outlet 215.

In an implementation mode, the motor 212 can be a brushless motor designed to operate at high speeds (e.g., over 30000 revolutions per minute) and low power (e.g., up to 15 W, 3 W during normal operation), and can be driven by a DC power supply. This high-speed and low power parameter provides excellent drying performance, and drying hair quickly as a traditional 2000 W hair dryer, and with significantly reduced power use.

As shown in FIGS. 5 and 6, in one embodiment, the first heating element 213 is located within the air duct housing 211 of the air supply duct 21 for heating the airflow. When the control unit 30 controls the first heating element 213 and the motor 212 to work together, it enters a blowing hot air mode. It can be understood that the blowing hot air mode is another blowing mode. In the blowing hot air mode, the hot air dries the hair with hot air, accelerating the drying efficiency of wet hair.

In an implementation mode, 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 straightening plate 12 are two separate heating systems of this device and they do not affect each other. One of the two can work independently or together.

As shown in FIGS. 5 and 6, in one embodiment, an air guide structure 40 is provided at a connection position between the airflow channel 22 and the air supply duct 21 to change the airflow direction. The air guide structure 40 changes the airflow direction inside the air supply duct 21 to allow the airflow to be blown out through the airflow channel 22.

As shown in FIG. 6, in one embodiment, the air guide structure 40 includes a base frame 41 and multiple air guide plates 42 that are inclinedly provided on the base frame 41. The base frame 41 is installed in the air supply channel 211, the multiple air guide plates 42 are spaced along a flow path of the airflow, an inclination angle of the multiple air guide plates 42 gradually decreases along the flow path of the airflow.

The inclinedly provided air guide plates 42 is conducive to guiding the airflow outwardly from the air outlet 215 in a direction of the airflow, so that the airflow is evenly dispersed and blown out from the air outlet, ensuring the styling effect of the hairstyle. Secondly, because the airflow at a front end is relatively large, the airflow at a rear end gradually decreases. Therefore, the inclination angle at the front end of the air guide plate 42 is designed to be larger than that at the rear end of the air guide plate 42 to ensure that the airflow with high airflow at the front end is evenly dispersed and blown out, while the airflow with reduced airflow at the rear end is blown out to ensure that the airflow at the rear end blows enough air onto the hair, thereby achieving a good styling effect. In an implementation mode, the inclination angle at the front end of air guide plate 42 is 45°, the inclination angle at the rear end of the air guide plate 42 is 90°

As shown in FIG. 5, in one embodiment of the present application, an arm 11 with an air duct housing 211 includes a lower shell 13 and an upper shell 14, the upper shell 14 and the lower shell 13 are spliced and connected to form the air supply duct 21. A sealing strip 15 is provided between the lower shell 13 and the upper shell 14 for the air outlet 215 to prevent air leakage from a connection position between the lower shell 13 and the upper shell 14. In an implementation mode, the sealing strip 15 is a silicone strip.

As shown in FIG. 6, in an implementation mode, the control unit 30 is a PCB board, which is provided in the air supply duct 21. The airflow in the air supply duct 21 can effectively take away heat of the PCB board and improve its service life.

In one embodiment, the control unit 30 controls the motor 212 and the straightening plate 12 to work together, and thereby entering a straightening hair and blowing cold air mode. It can be understood that the straightening hair and blowing cool air mode is one of straightening hair and blowing modes. For example, during a process of straightening dry hair, the blowing cool air mode quickly cools the hair to better care the hair.

In one embodiment, the control unit 30 controls the first heating element 213, the motor 212, and the second heating element in the straightening plate 12 to work together, and thereby entering a straightening hair and blowing hot air mode. It can be understood that the straightening hair and blowing hot air mode is another straightening hair and blowing mode. In the straightening hair and blowing hot air mode, one pair of straightening plates 12 clamp hair at an upper end for heating, the other pair of straightening plates 12 clamps hair at a lower end for heating. The airflow channel 22 guides the airflow to dry hair at a middle. During a process of pulling the device to straighten hair, the airflow channel 22 continues to air dry heated hair by one pair of straightening plates 12, while the other pair of straightening plates 121 reheats the hair after blowing by the airflow channel 22, thereby straightening hair through a primary heating, air drying, and straightening hair through a secondary heating are performed. Heat generated by the straightening plates 12 and the air duct unit can quickly remove moisture from the wet hair, thereby shortening the styling time and improving the styling efficiency.

As shown in FIGS. 7 and 8, in one embodiment, the airflow channel 22 runs through one arm 11 and is connected 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 to flow out. The air outlet 215 is located between two corresponding straightening plates 12, and the airflow channel 22 is located between the two corresponding straightening plates 12. The airflow channel 22 forms a guide for the airflow blown out by the air outlet 215, effectively preventing airflow turbulence and basically not affecting the airflow velocity and volume.

In one embodiment of the present application, the straightening plate 12 on one arm 11 is arranged at a certain distance from the air outlet 215, the straightening plate 12 on the other 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 straightening plate 12 and affecting the heat of the straightening plate 12.

When in the straightening hair and blowing hot air mode or straightening hair and blowing cold air mode, the straightening plate 12 on the two arms 11 clamps hair 1 for straightening hair. At the same time, the air outlet 215 guides high-speed airflow through hair 1 located at a position of the airflow channel 22 and directly blows it out from the airflow channel 22, allowing the airflow to dry the wet hair, thereby shortening the styling time, and improving the styling efficiency.

When in the blowing hot air or blowing cold air mode, the styling surface 101 is closed. At this time, the air outlet 215 and the airflow channel 22 are close to each other, and the airflow channel 22 forms a guide for the airflow blown out by the air outlet 215. The consumer holds the device to bring an outer side of the airflow channel 22 closer to the hair, and the airflow blows from the airflow channel 22 onto the hair to complete the drying of the hair.

In one embodiment, as shown in FIGS. 1, 2, 7, and 8, the airflow channel 22 is a hollow hole that runs through the corresponding arm 11 in a straight line. Multiple air outlets 215 are spaced and arranged in two rows on the styling surface 101 of the corresponding arm 11, the two rows of air outlets 215 are facing the hollow holes. By designing the hollow holes into large-diameter rectangular holes, it is possible to reduce obstacles during ventilation and ensure smooth ventilation. The multiple air outlets 215 are designed to be multiple, and the multiple air outlets 215 are holes with small diameter. When the airflow is transported from the front end (large diameter) of the air supply duct 211 to an end of the air outlet 215, the airflow speed increases, which can further shorten the styling time and improve the styling efficiency. The air outlet 215 is designed to be arranged in two rows, which can increase a coverage area of the air outlet and improve a uniformity of the ventilation, thereby further improving the styling efficiency.

As shown in FIGS. 2, 3, 4, 5, 7, and 8, in one embodiment, a dual functional channel 50 with low-pressure airflow and drainage is provided on the styling surface of the arm 11 with the air supply duct 21. The dual function channel 50 has a drainage function and provides space for low-speed airflow acceleration. The dual function channel 50 is facing toward the airflow channel 22 directly.

During a process of pulling hair, hair with moisture will be scraped and moved by the straightening plate 12. Scraped moisture will fall into the dual function channel 50 and then be discharged from the dual function channel 50, thereby avoiding the moisture from falling into the air inlet and air outlet 215 and affecting a component in the air duct housing 211. At the same time, a design of the dual function channel 50 increases a distance between the air outlet 215 and the straightening plate 12, effectively avoiding the high-speed airflow blowing on the straightening plate 12 and affecting the heat of the straightening plate 12.

In one embodiment of the present application, a height of a clamping surface of the straightening plate 12 is higher than a height of the water inlet of the dual function channel 50, thereby ensuring that the moisture scraped out by the straightening plate 12 can smoothly fall into the dual function channel 50.

As shown in FIGS. 7 and 8, in an implementation mode, there are two dual function channels 50 located on one side of the corresponding two straightening plates 12. One dual function channel 50 is configured to collect the moisture scraped out by the first pair of straightening plates 12, while the other dual function channel 50 is configured to collect the moisture scraped out by the second pair of straightening plates 12.

As shown in FIGS. 7 and 8, in one embodiment of the present application, the dual function channel 50 includes a water inlet 51 and a water outlet 52. The water inlet 51 is formed by an inner side of the styling surface 101 of the first arm 111 being concave and facing downward, the water inlet 51 is located on one side of the air outlet 215. In an implementation mode, the water inlet 51 is located between the air outlet and a corresponding straightening plate. The water outlet 52 is formed by a bottom wall of the water inlet 51 being concave and facing downward and runs through the first arm 111, that is, the water outlet 52 is located on the rear of the arm 111. For example, an aperture of the water inlet 51 is larger than that of the water outlet 52, that is, the water inlet 51 is a large-diameter space for the collection of water, and the water outlet 52 is a small-diameter hole for the drainage of water.

As shown in FIG. 7, in one embodiment of the present application, multiple grids 53 are spaced on an opening position of an upper of the water inlet 51, effectively reducing hair and impurities to entry into the water inlet 51. The grid 53 is provided with an inclined surface towards an end face of the airflow channel 22, which facilitates moisture to flow into the dual functional channel.

As shown in FIG. 8, in one embodiment of the present application, the rear of the first arm 111 is an arc-shaped structure, and there are multiple water outlets 52, which are spaced in a middle area of the arc-shaped structure. By designing the rear of the first arm 111 as an arc-shaped structure, and the multiple water outlets 52 are concentrated in the middle area of the arc-shaped structure, it is easy to guide and discharge water.

As shown in FIGS. 2-7, in one embodiment of the present application, opening edges at an upper of the two rows of the air outlets 215 are jointly surrounded by a rib 60, which can prevent water from permeating into an interior of the airflow channel 22 along the air outlet 215. As shown in FIG. 8, two rows of the air outlets 215 form a connection line L with a corresponding edge of the rib 60. Two connection lines L extend to an inner wall of the airflow channel 22 and form a high-pressure zone A1 in the air flow channel 22. Areas in the airflow channel 22 except for high-pressure zone A1 and the dual functional channel 12 jointly form a low-pressure zone A2. The high-speed airflow in high-pressure zone A1 will drive the airflow in the low-pressure zone A2 to increase and flow velocity to become faster, accelerated airflow in the low-pressure zone A2 flows towards the airflow channel 22, further drying wet hair. The dual function channel 12 not only has drainage function, but also provides space for the flow of the airflow in the low-pressure area A2, which increases a flow time of airflow in the low-pressure area A2 within the dual function channel 12, thereby accelerating the flow rate of the airflow in the low-pressure area A2.

In one embodiment of the present application, two pairs of straightening plates 12 are located on one side of the low-pressure area A2, the high-speed airflow in the high-pressure area A1 will not blow to the straightening plates 12 on the side of the low-pressure area A2, thereby effectively avoiding a problem of the high-speed airflow affecting the heat of the straightening plates 12.

The present disclosure is based on the above-mentioned hair straightener hair duct and provides a styling method for the hair straightener air duct. The control unit 30 controls the hair straightener unit and the air duct unit to work alone or together, entering the hair straightening mode, blowing mode, or hair straightening and blowing mode.

In the blowing mode, the control unit 30 controls the air duct unit to work and the hair straightening unit does not to work. There are two blowing modes: a first is a blowing cold air mode and a second is a blowing hot air mode.

In the straightening hair and blowing mode, the control unit 30 controls the air duct unit and the straightening hair unit wo work together. The hair straightening and blowing mode is divided into two types: a first is straightening hair and blowing cold air mode, a second is straightening hair and blowing hot air mode.

Overall, it includes the following five modes: (1) strengthening hair mode; (2) blowing cold air mode; (3) blowing hot air mode; (4) strengthening hair and blowing hot air mode; (5) straightening hair and blowing cool air mode.

In each mode, working status of the second heating element, motor 212, and first heating element 213 controlled by the control unit 30 on the straightening plate 12 are as follows:
