[0031] To clearly illustrate the solutions of the present invention, preferred embodiments are provided below and described in detail with reference to the accompanying drawings. The following description is merely illustrative in nature and is not intended to limit the application or use of the present disclosure. It should be understood that throughout the drawings, corresponding reference numerals indicate identical or corresponding parts and features.

[0032] As shown in Figures 1 to 13, the present invention provides a hair-drying assembly, comprising a cylindrical hair-curling outer barrel 1 and a built-in air flow distributor 2 installed in the hair-curling outer barrel 1, wherein the outer surface of the hair-curling outer barrel 1 extends to form a self-priming arc surface 10 for curling hair, and the hair-curling outer barrel 1 is provided with a plurality of long strip air outlets 11, and the air flow blown out by the air outlets 11 flows along the self-priming arc surface, the hair-curling outer barrel 1 is an integral component, and the air flow distributor 2 is also an integral component, and the air flow distributor 2 is sleeved in the hair-curling outer barrel 1, and further comprises an end cap 3 installed on the top of the hair-curling outer barrel 1, an air flow energy unloading space 31 is formed in the end cap 3, and a plurality of ventilation holes 32 are formed on the top of the hair-curling outer barrel 1, and the ventilation holes 32 are communicated with the air flow energy unloading space 31. The air outlet 11 in the present invention is formed on the hair curling outer barrel 1. The hair curling outer barrel 1 and the air flow distributor 2 are both complete independent components. During installation, the two components can be fitted together, making installation more convenient. In the prior art, the airflow at the end of the hair curling outer barrel 1 will form turbulence. The turbulence affects a certain length of the end of the air outlet 11, causing it to not have a curling effect. Therefore, during use, the end of the hair curling outer barrel 1 does not have a curling effect, affecting the entire use. The present invention provides an airflow unloading space 31, which extends the flow distance of the airflow, so that turbulence is formed in the airflow unloading space 31 instead of at the end of the air outlet 11. This ensures that the end of the air outlet 11 is not affected by the turbulence, extends the curling length of the air outlet 11, and ensures that the entire air outlet 11 has a curling effect, thereby improving the use effect.

[0033] Referring to Figures 1 to 13 , in the above-described embodiment of the present invention, the inner surface of the hair curling outer barrel 1 forms a plurality of inner curved air guide surfaces 12, and the air flow distributor 2 is formed with a plurality of outer curved air guide surfaces 26. An air guide channel 4 is formed between the inner curved air guide surfaces 12 and the outer curved air guide surfaces 26, and the air guide channel 4 communicates with the air outlet 11. The air guide channel 4 is formed between the inner curved air guide surfaces 12 and the outer curved air guide surfaces 26. After being guided by the curved surfaces, the high-pressure airflow flows along the self-priming curved surface 10 of the hair curling outer barrel 1, forming an arc-shaped blowing pattern. The air guide channel 4 provides a better air guiding effect.

[0034] Referring to Figures 1 to 13 , the above-described embodiment of the present invention further includes a cross-section of the hair curling outer barrel 1 presenting multiple arcuate sections 13, with the ends of two adjacent arcuate sections 13 offset to form the air outlet 11. This embodiment utilizes six arcuate sections 13, although five, eight, or nine segments may also be employed, depending on the size of the hair curling outer barrel 1. Each arcuate section 13 has an outwardly angled outer end 131 and an inwardly tapered inner end 132. The inner end 132 of the preceding arcuate section 13 and the outer end 131 of the succeeding arcuate section 13 form the air outlet 11. The end surface of the air outlet 11 is perpendicular to the self-inhaling arcuate surface 10 of the arcuate section 13, so that the air blown out of the air outlet 11 is tangential to the self-inhaling arcuate surface 10 of the arcuate section 13 and can flow along the self-inhaling arcuate surface 10 of the arcuate section 13, forming an arc-shaped wind.

[0035] 1 to 13 , in the above-described embodiments of the present invention, a sealing surface 27 is further provided on the airflow distributor 2 , and the sealing surface 27 contacts the inner air guide arc surface 12 . The sealing surface 27 is sealedly connected to the inner air guide arc surface 12 to prevent the airflow in the air guide channel 4 from flowing back into the airflow distributor 2 .

[0036] Referring to Figures 1 to 13 , the above-described embodiments of the present invention further include four to ten air outlets 11 distributed along a circumference, with the airflow from the multiple air outlets 11 relayed to form a circular wind. In this embodiment, there are six air outlets 11 . This circular wind can wrap hair around the outer barrel 1, facilitating hair drying.

[0037] Referring to Figures 1 to 13 , in the above-described embodiment of the present invention, a plurality of airflow dividers 33 are provided within the airflow energy unloading space 31. These airflow dividers 33 are arranged in a cross-shaped configuration, dividing the airflow energy unloading space 31 into multiple spaces that converge at the top of the airflow energy unloading space 31. This structure further reduces turbulence and does not affect the end of the curling outer barrel 1, allowing the end of the curling outer barrel 1 to still curl hair.

[0038] Referring to Figures 1 to 13, in the above-described embodiment of the present invention, a top plate 21 is provided on the top of the airflow distributor 2. A plurality of airflow holes 22 are provided on the top plate 21, and the airflow holes 22 are aligned with the ventilation holes 32. The airflow at the end of the airflow distributor 2 is discharged into the airflow unloading space 31 through the airflow holes 22, further reducing the generation of turbulence. In this embodiment, there are six airflow holes 22 and six ventilation holes 32, and the airflow holes 22 correspond one-to-one with the ventilation holes 32.

[0039] Referring to Figures 1 to 13 , in the above-described embodiment of the present invention, the air distributor 2 is provided with air distribution plates 23, with air outlet holes 24 formed between adjacent air distribution plates 23. The air distribution plates 23 direct the airflow entering axially in a radial direction. In this embodiment, the air distribution plates 23 have a trapezoidal structure, and therefore, the air outlet holes 24 formed by the two air distribution plates 23 also have a trapezoidal structure, facilitating airflow.

[0040] Referring to Figures 1 to 13 , in the embodiments of the present invention, the distance between adjacent air distribution plates 23 is adjusted based on the airflow intensity distribution. In the present invention, the distance between air distribution plates 23 is unequal. Adjusting the distance between the air distribution plates 23 adjusts the size of the air outlets 24, maintaining consistent airflow through the air outlets 24 and enhancing the curling effect.

[0041] 1 to 13 , in the above-described embodiment of the present invention, an air inlet channel 25 is formed in the center of the air flow distributor 2, and the air inlet channel 25 communicates with the air outlet 24. In the present invention, the air inlet channel 25 is formed only in the center of the air flow distributor 2, which facilitates the air flow distribution of the air flow distributor 2.

[0042] 1 to 13 , in the above embodiment of the present invention, one end of the outer barrel 1 is provided with an interface 15 for connecting to a hair dryer. The hair dryer is connected to the interface 15 to facilitate the connection between the hair dryer and the blowing assembly.

[0043] Referring to Figures 1 to 13 , the above-described embodiment of the present invention further includes a plurality of support legs 28 disposed at the bottom of the air distributor 2. The support legs 28 abut against the bottom inner wall of the outer curling barrel 1. The support legs 28 provide support and position the entire air distributor 2 to prevent deflection.

[0044] A hair dryer includes a main body for generating airflow and a blowing assembly mounted on the main body, wherein the blowing assembly is the blowing assembly described in the above-mentioned embodiment. The main body in the present invention can be an existing hair dryer or hair dryer, and its primary function is to generate a high-speed airflow for drying hair. The blowing assembly is mounted at the air outlet of the hair dryer or hair dryer.

[0045] In summary, the above contents are merely embodiments of the present invention and are intended only to illustrate the principles of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
