CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] 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.TECHNICAL FIELD

[0002] 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.BACKGROUND

[0003] 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.

[0004] 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.SUMMARY

[0025] Below, a further detailed description of the present disclosure will be provided in combination with the accompanying drawings and specific embodiments.

[0026] In this embodiment, referring to FIGS. 1-7, a specific structure of a hair dryer head for straightening hair includes a blowing shell 1 and a hollow connection tube 3 configured to connect with a blowing host 2. The hollow connection tube 3 is quickly connected with the blowing host 2 through an L-shaped clamp groove.

[0027] The blowing shell 1 includes a first blowing part 101 and a second blowing part 102. Opposing surfaces of the first blowing part 101 and the second blowing part 102 are 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 part 101 and the second blowing part 102 near the hollow connection tube 3 are connected to the hollow connection tube 3. A hair clip cavity 112 configured to pass through the hair bundle is provided between the first blowing part 101 and the second blowing part 102. One ends of the first blowing part 101 and the second blowing part 102 away from the hollow connection tube 3 is provided with a hair guide opening 113 that is conductive an introduction of the hair bundle and connecting with the hair clip cavity 112. The hair guide opening 113 is combined with the hair clip cavity 112 in a Y-shaped structure, a surface of the hair guide opening 113 is a smooth arc-shaped structure. The arc-shaped structure makes it easier to quickly and smoothly introduce the hair bundle.

[0028] A side of the first blowing part 101 in this embodiment is provided with three first external blowing ports 103, a side of the second blowing part 102 is provided with three second external blowing ports 104 on the same side as the first external blowing ports 103. Opposite surfaces of the first blowing part 101 and the second blowing part 102 are respectively provided with five first internal blowing ports 105 and five second internal blowing ports 106. Blowing directions of the first internal blowing port 105 and the second internal blowing port 106 are inclined to a plane where it is located, and airflow directions blown out by the first internal blowing port 105, the second internal blowing port 106, the first external blowing port 103, and the second external blowing port 104 are all in the same direction.

[0029] The blowing directions of the first external blowing port 103 and the second external blowing port 104 are 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.

[0030] An interior of the first blowing part 101 is provide with a first air duct that is connected to the first external blowing port 103 and the first internal blowing port 105, and an interior of the second blowing part 102 is provided with a second air duct that is connected to the second external blowing port 104 and the second internal blowing port 106. Air inlets of the first air duct and the second air duct both face the hollow connection tube 3. When the blowing host 2 is working, high-speed airflow blown out enters the first air duct and the second air duct along the hollow connection tube 3, and finally blows out along the first internal blowing port 105, the second internal blowing port 106, the first external blowing port 103, and the second external blowing port 104 respectively. The blowing host 2 can be set to blow hot or cold air, and different blowing intensities can also be set.

The first arc-shaped boosting slope 109 wraps 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 slope 109 in a direction of the first external blowing port 103. An end face of the second air duct face away from the first air duct is provided with a second arc-shaped boosting slope 110, 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 slope 110 in a direction of the second external blowing port 104. Providing with the first arc-shaped boosting slope 109 and the second arc-shaped boosting slope 110, 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.

[0033] As shown in FIGS. 1-3, in order to facilitate an installation of the blowing shell 1, an outer shell 114 is fixedly installed on a periphery of the blowing shell 1. The outer shell 114 is clamped and installed with the blowing shell 1. Two positioning blocks 115 are provided on an inner wall of one end of the outer shell 114 near the hollow connection tube 3. An end of the hollow connection tube 3 near the outer shell 114 is provided with a locking tooth 301 configured to clamp into the positioning block 115. The locking tooth 301 has a certain degree of elasticity and is easy to quickly clamp into the positioning block 115. When installing the hollow connection tube 3, it can be quickly clamped into the positioning block 115 through the locking tooth 301 so as to achieve a purpose of quick installation. There are two guide columns 116 on an inner wall of one end of the outer shell 114 near the hollow connection tube 3. An end of the hollow connection tube 3 near the outer shell 114 is provided with a guide groove 302 configured to penetrate the guide columns 116. The hollow connection tube 3 is locked with the blowing shell 1 by two screws. The guide groove 302 can be used for quick positioning to avoid installation misalignment. During installation, the guide columns 116 can quickly penetrate into the guide groove 302 so as to achieve fast and accurate installation.

[0034] When in use, as shown in FIGS. 6 and 7, the hair dryer head is docked with the blowing host 2, and a L-shaped clamp groove of the hollow connection tube 3 is used to quickly dock with the blowing host 2, while also enabling quick disassembly, as shown in FIG. 7. When the blowing host 2 is 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 3. Under diversion and turning action of the first arc-shaped air guide plate 107 and the second arc-shaped air guide plate 108, it is finally blown out simultaneously along the first internal blowing port 105, the second internal blowing port 106, the first external blowing port 103, and the second external blowing port 104. During use, the hair bundle enters the hair clip cavity 112 along the hair guide opening 113 and passes through the hair clip cavity 112. The user only needs to clamp the hair in the hair clip cavity 112 and 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 port 103 and the second external blowing port 104 is evenly blown to the surface of hair, while the hot air blown out by the first internal blowing port 105 and the second internal blowing port 106 is also evenly blown to the hair. Blowing directions of the first internal blowing port 105 and the second internal blowing port 106 are inclined at an angle, and the blowing directions of the first external blowing port 103 and the second external blowing port 104 are 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.
