Hair Dryer Head for Straightening Hair

This application claims priority to Chinese Patent Application No.202421317302.7, filed on June 07, 2024, which is hereby incorporated by reference in its entirety.

The present disclosure relates to the field of hairdressing technologies, and in particular, to a hair dryer head that can be quickly dry and straighten straight hair.

For a long time, consumers have mostly used splints for hair care. Which brings about a long-term drawback, that is the ultra-high temperature caused by splints, which can easily lead to hair becoming dry, yellow, brittle, and lacking elasticity. As a traditional heating type hairdressing electric heater, the splints heat a heating element MCH or PTC or heating wire of the straightener through an electric current and conduct it to the aluminum plate or ceramic plate to generate heat. After heating, surface temperature of the splints can reach up to 200 ° C. If used frequently, it can directly cause the loss of hard protein and keratin in the hair, thereby resulting in dry, yellow, easily broken, faded, and dull hair. Over time, this can lead to increased dandruff, split hair, and even hair loss, and causing serious damage to hair health.

There is a type of blowing comb on the market that can avoid burning hair and cause less damage to hair compared to splints. The blowing comb is a hairdressing tool that combines a comb and a hair dryer, usually including a combing part, a hair dryer body, and a connection part. The combing part has comb teeth, and the blowing body is responsible for generating airflow, which is combined together through the connection part (which may be a direct or magnetic connection). Some high-class blowing combs are also equipped with different wind speed and temperature adjustment functions to adapt to different hair qualities and styling needs. The blowing combs mainly rely on airflow to dry and shape hair, and the straightening effect is relatively weak. During use, while drying hair through a row of hair blowing holes in the same direction as the comb teeth, the hair can be straightened through the comb teeth. The blowing volume of a single row of hair blowing holes is limited, and only one direction can be used to dry hair. It is difficult to achieve the effect of quickly and evenly drying hair. For rough or curly hair, the blowing combs may not achieve a desired straightening effect. Furthermore, using the blowing combs for straightening take a longer time. Due to the limited straightening effect of the blowing combs, users may need to spend more time combing and styling hair to achieve satisfactory straightening results. In addition, when using the blowing combs, one also needs to rely on skills. Achieving the straight hair effect with the blowing combs requires certain skills and practice, including appropriate combing direction, angle, and speed. If the users do not master the correct use skills, it may affect the straight hair effect.

A purpose of the present disclosure is to solve the above defects by providing a hair dryer head that can be quickly dry and straighten straight hair, solving the technical problem in the prior art that only a one-way blowing makes it difficult to achieve fast drying and straightening hair.

Below, a further detailed description of the present disclosure will be provided in combination with the accompanying drawings and specific embodiments.

In this embodiment, referring to, a specific structure of a hair dryer head for straightening hair includes a blowing shelland a hollow connection tubeconfigured to connect with a blowing host. The hollow connection tubeis quickly connected with the blowing hostthrough an L-shaped clamp groove.

The blowing shellincludes a first blowing partand a second blowing part. Opposing surfaces of the first blowing partand the second blowing partare mutually parallel planes, which facilitate a smooth pulling of hair bundle and render the hair blowing and straightening process smoother. One ends of the first blowing partand the second blowing partnear the hollow connection tubeare connected to the hollow connection tube. A hair clip cavityconfigured to pass through the hair bundle is provided between the first blowing partand the second blowing part. One ends of the first blowing partand the second blowing partaway from the hollow connection tubeis provided with a hair guide openingthat is conductive an introduction of the hair bundle and connecting with the hair clip cavity 112. The hair guide openingis combined with the hair clip cavityin a Y-shaped structure, a surface of the hair guide openingis a smooth arc-shaped structure. The arc-shaped structure makes it easier to quickly and smoothly introduce the hair bundle.

A side of the first blowing partin this embodiment is provided with three first external blowing ports 103, a side of the second blowing partis provided with three second external blowing portson the same side as the first external blowing ports. Opposite surfaces of the first blowing partand the second blowing partare respectively provided with five first internal blowing portsand five second internal blowing ports. Blowing directions of the first internal blowing portand the second internal blowing portare inclined to a plane where it is located, and airflow directions blown out by the first internal blowing port, the second internal blowing port, the first external blowing port, and the second external blowing portare all in the same direction.

The blowing directions of the first external blowing portand the second external blowing portare both inclined inward at an angle along directions opposite to each other. In an implementation,the angle is designed to 45 degrees, spraying two rows of high-speed airflow at 45-degree angle to converge and form a strong downward airflow, thereby providing a downward pulling force required for straightening hair, replacing a clamping force required by a traditional splint and straightening method, evenly acting on the hair bundle. A user only needs to clamp the hair and pull it down so as to start an operation, and then straighten the hair while drying wet hair.

An interior of the first blowing partis provide with a first air duct that is connected to the first external blowing portand the first internal blowing port, and an interior of the second blowing partis provided with a second air duct that is connected to the second external blowing portand the second internal blowing port. Air inlets of the first air duct and the second air duct both face the hollow connection tube. When the blowing hostis working, high-speed airflow blown out enters the first air duct and the second air duct along the hollow connection tube, and finally blows out along the first internal blowing port, the second internal blowing port, the first external blowing port, and the second external blowing portrespectively. The blowing hostcan be set to blow hot or cold air, and different blowing intensities can also be set.

As shown in, in order to increase wind speed, the first air duct is provided with a first arc-shaped air guide platehaving a same number as the first external blowing port, specifically three first arc-shaped air guide plates. The second air duct is provided with a second arc-shaped air guide platehaving a same number as the second external blowing port, specifically three second arc-shaped air guide plates. The first arc-shaped air guide plateand the second arc-shaped air guide plateare respectively used to separate the first air duct and the second air duct into independent small air ducts, so as to more concentrate the air volume and achieve an effect of increasing pressure and speed. The first arc-shaped air guide plateand the second arc-shaped air guide platealso play a turning role. There are also four first longitudinal bafflesprovided in the first air duct for diverting the flow of adjacent two first internal blowing ports. Heights of adjacent two first longitudinal bafflesgradually decreases from an end away from the hollow connection tubealong an end close to the hollow connection tube. There are also four second longitudinal baffles provided in the second air duct for diverting the flow of adjacent two second internal blowing ports, and heights of the adjacent two second longitudinal baffles gradually decrease from the end away from the hollow connection tubealong the end close to the hollow connection tube.

As shown in, one end face of the first air duct away from the second air duct is provided with a first arc-shaped boosting slope. The first arc-shaped boosting slopewraps around an outer side of the first air duct, and a volume of the first air duct decreases from one end of the first arc-shaped boosting slopein a direction of the first external blowing port. An end face of the second air duct face away from the first air duct is provided with a second arc-shaped boosting slope, which wraps around an outer side of the second air duct. A volume of the second air duct decreases from one end of the second arc-shaped boosting slopein a direction of the second external blowing port. Providing with the first arc-shaped boosting slopeand the second arc-shaped boosting slope, an overall structure of the air duct gradually decreases from large to small. By providing with the arc-shaped structure, the airflow velocity is faster to achieve the effect of increasing pressure.

As shown in, in order to facilitate an installation of the blowing shell, an outer shellis fixedly installed on a periphery of the blowing shell. The outer shellis clamped and installed with the blowing shell. Two positioning blocksare provided on an inner wall of one end of the outer shellnear the hollow connection tube. An end of the hollow connection tubenear the outer shellis provided with a locking toothconfigured to clamp into the positioning block. The locking toothhas a certain degree of elasticity and is easy to quickly clamp into the positioning block. When installing the hollow connection tube, it can be quickly clamped into the positioning blockthrough the locking toothso as to achieve a purpose of quick installation. There are two guide columnson an inner wall of one end of the outer shellnear the hollow connection tube. An end of the hollow connection tubenear the outer shellis provided with a guide grooveconfigured to penetrate the guide columns. The hollow connection tubeis locked with the blowing shellby two screws. The guide groovecan be used for quick positioning to avoid installation misalignment. During installation, the guide columnscan quickly penetrate into the guide grooveso as to achieve fast and accurate installation.

When in use, as shown in, the hair dryer head is docked with the blowing host, and a L-shaped clamp groove of the hollow connection tubeis used to quickly dock with the blowing host, while also enabling quick disassembly, as shown in. When the blowing hostis working, it can blow hot or cold air. When the hot air is blown out, the high-speed hot air enters the first air duct and the second air duct through the hollow connection tube. Under diversion and turning action of the first arc-shaped air guide plateand the second arc-shaped air guide plate, it is finally blown out simultaneously along the first internal blowing port, the second internal blowing port, the first external blowing port, and the second external blowing port. During use, the hair bundle enters the hair clip cavityalong the hair guide openingand passes through the hair clip cavity. The user only needs to clamp the hair in the hair clip cavityand pull it down to start the operation. The operation is simple and easy to use. During the pulling process, the high-speed hot air blown out by the first external blowing portand the second external blowing portis evenly blown to the surface of hair, while the hot air blown out by the first internal blowing portand the second internal blowing portis also evenly blown to the hair. Blowing directions of the first internal blowing portand the second internal blowing portare inclined at an angle, and the blowing directions of the first external blowing portand the second external blowing portare inclined inward at the angle along directions opposite to each other. After forming the angle, the high-speed airflow sprayed out at this angle provides the downward pulling force required to straighten hair that can quickly dry and straighten hair, and the high-speed airflow can straighten hair while drying wet hair, thereby simplifying a daily styling process in one step.
