Please refer toFIGS.1to8, 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 unit30. 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 unit30is 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 arms11that are hinged with each other at one end of the arm. Styling surfaces101of both arms are provided with two opposite straightening plates12, which heat and straighten hair.

The air duct unit includes an air supply duct21located on one arm and an airflow channel22located 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 duct21is located on one side of the two straightening plates12.

The control unit30, provided on any one arm11, 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 plates12and pulls the device along a direction of hair extension. Two pairs of straightening plates12cause 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 plates12also straighten the hair for styling purposes.

In the blowing mode, the air outlet215of the air supply duct21delivers airflow, and the consumer aligns the airflow channel22with the hair, allowing a blown airflow to dry the hair.

In the straightening hair and blowing mode, wet hair is sandwiched between the styling surface101, and the device is pulled along the direction of the hair extension. Two pairs of straightening plates12straighten the hair, and synchronously, the air duct unit dries the hair1, completing the straightening and drying of the hair.

More specifically, as shown inFIG.1, in one embodiment, the two arms11are a first arm111and a second arm112, respectively. One end of the first arm111and the second arm112are hinged with each other, so that the first arm111and the second arm112cooperate, providing the styling surface101with a closed state (seeFIG.1) and an open state (seeFIG.2).

As shown inFIGS.1and2, one use mode is: when the styling surfaces101of the first arm111and the second arm112close and clamp the hair, the hair straightening unit is activated, and the straightening plate12can straighten the hair. A second use mode is: when the styling surfaces101of the first arm111and the second arm112are 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 arm111and the second arm112when in an open state.

As shown inFIG.1, multiple buttons70are provided on an outer wall of one arm11, including a switch button, a speed control button, and different mode buttons.

As shown inFIGS.1and2, a display unit80is also provided on an outer wall of any one arm11, 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 unit80, so that a user can grasp a situation in a timely manner and adjust the styling method or strategy in real-time.

As shown inFIG.2, in one embodiment of the present application, the hair straightener air duct further includes a locking unit90for limiting an opening of the two arms. The locking unit90is located on any one arm, when in a closed state, the locking unit90can lock the two arms11together without manually pressing them down. The locking unit90includes a hook groove91located on one arm11and a push button92located on the other arm11. The push button92is provided with a locking hook, and after the push button92is pushed into place, the locking hook is locked with the hook groove91.

As shown inFIG.3, there are two straightening plates12spaced on the styling surface101of the two arms11. The straightening plates have a second heating element on them, which conducts heat to the straightening plate12when 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 outlet215of the air supply duct21and an airflow channel22are placed between left and right straightening plates12arranged at intervals, rendering reasonable use of space, and reducing the volume of the device. In an implementation mode, the straightening plate12is 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 inFIGS.4to6, in one embodiment, the air supply duct21has an air inlet and an air outlet215. The air inlet is located at a handle of the hair straightening air duct, and the air outlet215is located in a middle of the styling surface of the arm with the air supply duct and between the two straightening plates12. The air supply duct is provided with a motor212and a first heating element213, and the airflow is blown out from the air inlet214through the motor212and the heating element213. The air supply duct21further includes an air duct housing211located in one arm11, a motor212is built in the air duct housing211. When the control unit30only controls an operation of the motor212, 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 inFIG.5, in an implementation mode, the motor212includes an impeller202located on an output shaft of the motor211. The motor221drives the impeller202to rotate, and the airflow enters the airflow channel22through the air inlet214and is discharged through the air outlet215.

In an implementation mode, the motor212can 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 inFIGS.5and6, in one embodiment, the first heating element213is located within the air duct housing211of the air supply duct21for heating the airflow. When the control unit30controls the first heating element213and the motor212to 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 element213is an electric heating coil or other heating element. The first heating element213and the second heating element in the straightening plate12are 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 inFIGS.5and6, in one embodiment, an air guide structure40is provided at a connection position between the airflow channel22and the air supply duct21to change the airflow direction. The air guide structure40changes the airflow direction inside the air supply duct21to allow the airflow to be blown out through the airflow channel22.

As shown inFIG.6, in one embodiment, the air guide structure40includes a base frame41and multiple air guide plates42that are inclinedly provided on the base frame41. The base frame41is installed in the air supply channel211, the multiple air guide plates42are spaced along a flow path of the airflow, an inclination angle of the multiple air guide plates42gradually decreases along the flow path of the airflow.

The inclinedly provided air guide plates42is conducive to guiding the airflow outwardly from the air outlet215in 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 plate42is designed to be larger than that at the rear end of the air guide plate42to 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 plate42is 45°, the inclination angle at the rear end of the air guide plate42is 90°

As shown inFIG.5, in one embodiment of the present application, an arm11with an air duct housing211includes a lower shell13and an upper shell14, the upper shell14and the lower shell13are spliced and connected to form the air supply duct21. A sealing strip15is provided between the lower shell13and the upper shell14for the air outlet215to prevent air leakage from a connection position between the lower shell13and the upper shell14. In an implementation mode, the sealing strip15is a silicone strip.

As shown inFIG.6, in an implementation mode, the control unit30is a PCB board, which is provided in the air supply duct21. The airflow in the air supply duct21can effectively take away heat of the PCB board and improve its service life.

In one embodiment, the control unit30controls the motor212and the straightening plate12to 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 unit30controls the first heating element213, the motor212, and the second heating element in the straightening plate12to 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 plates12clamp hair at an upper end for heating, the other pair of straightening plates12clamps hair at a lower end for heating. The airflow channel22guides the airflow to dry hair at a middle. During a process of pulling the device to straighten hair, the airflow channel22continues to air dry heated hair by one pair of straightening plates12, while the other pair of straightening plates121reheats the hair after blowing by the airflow channel22, thereby straightening hair through a primary heating, air drying, and straightening hair through a secondary heating are performed. Heat generated by the straightening plates12and the air duct unit can quickly remove moisture from the wet hair, thereby shortening the styling time and improving the styling efficiency.

As shown inFIGS.7and8, in one embodiment, the airflow channel22runs through one arm11and is connected to the air outlet215of the air supply duct21. The airflow channel22is opposite to the air outlet215and guides the airflow to flow out. The air outlet215is located between two corresponding straightening plates12, and the airflow channel22is located between the two corresponding straightening plates12. The airflow channel22forms a guide for the airflow blown out by the air outlet215, effectively preventing airflow turbulence and basically not affecting the airflow velocity and volume.

In one embodiment of the present application, the straightening plate12on one arm11is arranged at a certain distance from the air outlet215, the straightening plate12on the other 11 is arranged at a certain distance from the airflow channel22. After the airflow is guided, it effectively prevents the airflow from blowing onto the straightening plate12and affecting the heat of the straightening plate12.

When in the straightening hair and blowing hot air mode or straightening hair and blowing cold air mode, the straightening plate12on the two arms11clamps hair1for straightening hair. At the same time, the air outlet215guides high-speed airflow through hair1located at a position of the airflow channel22and directly blows it out from the airflow channel22, 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 surface101is closed. At this time, the air outlet215and the airflow channel22are close to each other, and the airflow channel22forms a guide for the airflow blown out by the air outlet215. The consumer holds the device to bring an outer side of the airflow channel22closer to the hair, and the airflow blows from the airflow channel22onto the hair to complete the drying of the hair.

In one embodiment, as shown inFIGS.1,2,7, and8, the airflow channel22is a hollow hole that runs through the corresponding arm11in a straight line. Multiple air outlets215are spaced and arranged in two rows on the styling surface101of the corresponding arm11, the two rows of air outlets215are 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 outlets215are designed to be multiple, and the multiple air outlets215are holes with small diameter. When the airflow is transported from the front end (large diameter) of the air supply duct211to an end of the air outlet215, the airflow speed increases, which can further shorten the styling time and improve the styling efficiency. The air outlet215is 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 inFIGS.2,3,4,5,7, and8, in one embodiment, a dual functional channel50with low-pressure airflow and drainage is provided on the styling surface of the arm11with the air supply duct21. The dual function channel50has a drainage function and provides space for low-speed airflow acceleration. The dual function channel50is facing toward the airflow channel22directly.

During a process of pulling hair, hair with moisture will be scraped and moved by the straightening plate12. Scraped moisture will fall into the dual function channel50and then be discharged from the dual function channel50, thereby avoiding the moisture from falling into the air inlet and air outlet215and affecting a component in the air duct housing211. At the same time, a design of the dual function channel50increases a distance between the air outlet215and the straightening plate12, effectively avoiding the high-speed airflow blowing on the straightening plate12and affecting the heat of the straightening plate12.

In one embodiment of the present application, a height of a clamping surface of the straightening plate12is higher than a height of the water inlet of the dual function channel50, thereby ensuring that the moisture scraped out by the straightening plate12can smoothly fall into the dual function channel50.

As shown inFIGS.7and8, in an implementation mode, there are two dual function channels50located on one side of the corresponding two straightening plates12. One dual function channel50is configured to collect the moisture scraped out by the first pair of straightening plates12, while the other dual function channel50is configured to collect the moisture scraped out by the second pair of straightening plates12.

As shown inFIGS.7and8, in one embodiment of the present application, the dual function channel50includes a water inlet51and a water outlet52. The water inlet51is formed by an inner side of the styling surface101of the first arm111being concave and facing downward, the water inlet51is located on one side of the air outlet215. In an implementation mode, the water inlet51is located between the air outlet and a corresponding straightening plate. The water outlet52is formed by a bottom wall of the water inlet51being concave and facing downward and runs through the first arm111, that is, the water outlet52is located on the rear of the arm111. For example, an aperture of the water inlet51is larger than that of the water outlet52, that is, the water inlet51is a large-diameter space for the collection of water, and the water outlet52is a small-diameter hole for the drainage of water.

As shown inFIG.7, in one embodiment of the present application, multiple grids53are spaced on an opening position of an upper of the water inlet51, effectively reducing hair and impurities to entry into the water inlet51. The grid53is provided with an inclined surface towards an end face of the airflow channel22, which facilitates moisture to flow into the dual functional channel.

As shown inFIG.8, in one embodiment of the present application, the rear of the first arm111is an arc-shaped structure, and there are multiple water outlets52, which are spaced in a middle area of the arc-shaped structure. By designing the rear of the first arm111as an arc-shaped structure, and the multiple water outlets52are concentrated in the middle area of the arc-shaped structure, it is easy to guide and discharge water.

As shown inFIGS.2-7, in one embodiment of the present application, opening edges at an upper of the two rows of the air outlets215are jointly surrounded by a rib60, which can prevent water from permeating into an interior of the airflow channel22along the air outlet215. As shown inFIG.8, two rows of the air outlets215form a connection line L with a corresponding edge of the rib60. Two connection lines L extend to an inner wall of the airflow channel22and form a high-pressure zone A1in the air flow channel22. Areas in the airflow channel22except for high-pressure zone A1and the dual functional channel12jointly form a low-pressure zone A2. The high-speed airflow in high-pressure zone A1will drive the airflow in the low-pressure zone A2to increase and flow velocity to become faster, accelerated airflow in the low-pressure zone A2flows towards the airflow channel22, further drying wet hair. The dual function channel12not 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 A2within the dual function channel12, 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 plates12are located on one side of the low-pressure area A2, the high-speed airflow in the high-pressure area A1will not blow to the straightening plates12on the side of the low-pressure area A2, thereby effectively avoiding a problem of the high-speed airflow affecting the heat of the straightening plates12.

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 unit30controls 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 unit30controls 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 unit30controls 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, motor212, and first heating element213controlled by the control unit30on the straightening plate12are as follows:(1) when in the straightening hair mode: only the second heating element of the straightening plate12works, the motor and first heating element do not work;(2) when in the blowing cold air mode: only the motor212works, the first heating element (213) and second heating element do not work to blow out natural air;(3) when in the blowing hot air mode: only the motor212and the first heating element213work together, the second heating element does not work;(4) when in the straightening hair and blowing cool air mode: only the motor212and the second heating element work together, the first heating element213does not work;(5) when in the straightening air and blowing hot air mode: the first heating element213, motor212, and second heating element work together.

The above is only preferred embodiments of the present application and is not intended to limit it. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present application shall be included within the protection scope of the present application.
