In particular, hot hair dryers are used for a variety of purposes, such as drying substances (such as paint and hair), and cleaning or stripping surface layers.

[0003] At present, the hair dryers commonly seen on the market are mostly used for drying and assisting in styling hair. The widely used hair dryers are equipped with a heat drying hood (commonly known as a diffuser). The purpose is that when the hair dryer is used to dry the hair, the hood can be used to dry the curly hair, making the curly hair less likely to be messy and able to maintain the original curly hair shape after drying the hair. The diffuser guides the air flow so that the hair dryer has a better air outlet effect.

[0004] Prior art example 1, referring to patent document CN111150206A, discloses a diffuser and a hair dryer.

[0042] Embodiment 1

[0043] Reference Figures 1 to 10 , a hair care accessory 1 for a hair styling appliance 9, comprising:

[0044] A rear shell 2, which is detachably connected to the hair styling device 9, and an air inlet structure 6 is provided on the rear shell 2;

[0045] A front cover 3 is assembled with the rear shell 2 as a whole, an inner cavity air duct 4 is formed between the front cover 3 and the rear shell 2, and an air outlet structure 7 is opened at the front end of the front cover 3, and the air outlet structure 7 is connected with the air inlet structure 6 through the inner cavity air duct 4;

[0046] An air duct distribution bracket 5, which is arranged in the inner cavity air duct 4, and the air duct distribution bracket 5 divides the inner cavity air duct 4 into an outer air duct 41 and an inner air duct 42;

[0047] The air outlet structure 7 includes an outer air outlet section 7a and an inner air outlet section 7b. The outer air duct 41 is connected to the outer air outlet section 7a, and the inner air duct 42 is connected to the inner air outlet section 7b.

[0048] The above content is the basic structural scheme of the utility model. What is different from the prior art such as Example 1 and Example 2 is that the utility model adds an air duct distribution bracket 5 between the rear shell 2 and the front cover 3, which can reasonably divide the inner cavity air duct 4 into an outer air duct 41 and an inner air duct 42, and the air duct distribution bracket 5 can divert and guide the incoming air flow, so that part of the air flow flows to the outer air duct 41, and the other part of the air flow flows to the inner air duct 42. Furthermore, the airflow of the outer air duct 41 is eventually ejected to the outside through the outer air outlet section 7a, and the airflow of the inner air duct 42 is eventually ejected to the outside through the inner air outlet section 7b. In addition, according to the needs, the shape and specific installation position of the air duct distribution bracket 5 can be set to achieve the function of guiding and distributing the air volume to the outer air duct 41 and the inner air duct 42.

[0049] Embodiment 2

[0050] Reference Figure 3 to Figure 7In some embodiments of the present invention, the air outlet structure 7 includes a plurality of air outlet holes 71 and an air outlet column 72 , a portion of the air flow is ejected to the outside through the air outlet holes 71 , and another portion of the air flow is ejected to the outside through the air outlet column 72 .

[0051] Further, see Figure 7 The air outlet column 72 protrudes from the air outlet hole 71 to form a first height difference H1. The air outlet column 72 can support the head. Due to the existence of the first height difference H1, the air outlet is kept smooth to prevent the head from being damaged (burned) by being too close to the head, and the airflow is fully in contact with the hair to quickly dry the hair.

[0052] Preferably, refer to Figure 5 The outlet column 72 is provided with an air inlet 721 which is the same as the inner cavity air duct 4, and the side of the outlet column 72 is provided with a double-sided lateral air outlet slot 722, the air inlet 721 is connected with the double-sided lateral air outlet slot 722, and the outlet hole 71 is cross-shaped. The preferred shape of the outlet hole 71 and the structure of the outlet column 72 can realize multi-directional air outlet, so that the air outlet angle is wider, the air outlet area is larger, and the air flow fully contacts the hair, so that the hair can be dried quickly, and the hair blowing experience is improved.

[0053] Generally, the distance between the inner air duct 42 and the outer air duct 41 is shorter, so the outlet air temperature of the inner air outlet section 7b corresponding to the inner air duct 42 is relatively high and the wind speed is faster. Figure 7 In order to make the inner and outer air outlet effects more balanced, it is preferred that the outer air outlet section 7a protrude from the inner air outlet section 7b to form a second height difference H2 to extend the air outlet distance of the inner air duct 42, thereby making the inner and outer air outlet structures 7 more similar and the effects closer.

[0054] Embodiment 3

[0055] Reference Figure 8 In the embodiment, the air duct distribution bracket 5 is in the shape of a trumpet that expands outward from the back to the front, which plays the role of guiding and expanding the flow. The air duct distribution bracket 5 has an arc wall 53 (preferably including an inner wall and an outer wall) to reduce interference, make the air flow smoother, and reduce wind noise. Figure 3 The rear end face of the air duct distribution bracket 5 forms a diversion tip 51, which has an effective diversion effect. The front end face of the air duct distribution bracket 5 is evenly distributed with diversion ribs 54. The diversion ribs 54 can be used to separate the area in the annular direction, eliminate turbulence, and enable the airflow to flow forward evenly.

[0056] In some embodiments of the present invention, referring to Figure 9-10The rear shell 2 is provided with a wind-breaking body 21 protruding forward, and the wind-breaking body 21 extends into the inner air duct 42. The wind-breaking body 21 is used to break the wind and guide the flow, so that the overall noise is reduced and the wind speed loss is small, thereby reducing the power consumption of the hair dryer.

[0060] 2. Fixing structure: The first positioning column 31 and the first positioning groove 52 are provided with first fixing holes 311 in opposite positions, and the second positioning column 32 and the second positioning groove 23 are provided with second fixing holes 321 in opposite positions. The first fixing holes 311 and the second fixing holes 321 can be connected with fasteners (preferably screws, etc., not shown in the figure) respectively. Alternatively, the fixing can be achieved by connecting with buckles 33, gluing, etc., instead of fasteners, and the specific method is not particularly limited here.

[0061] Preferably, refer to Fig.10 The rear end of the air-breaking body 21 has an opening 211, and the opening 211 is detachably connected to the back cover 22. The second positioning column 32 is located at the front end of the air-breaking body 21. Therefore, when the back cover 22 is removed, the installation of the positioning structure and the fixing structure is convenient. After installation, the back cover 22 is assembled to cover the opening 211, so that the appearance of the air-breaking body 21 remains intact.

[0062] Through the coordinated use of the pre-positioning structure and the fixing structure, the front cover 3, the air duct distribution bracket 5 and the rear shell 2 can be assembled into one body.

[0063] Embodiment 5

[0064] Reference Figure 2 to Figure 4Since the hair care accessory 1 in the present invention cannot be used alone, it is generally docked at the air outlet of the hair dryer (hair styling appliance 9), so that the airflow blown by the hair dryer enters the hair care accessory 1, and is diffused and sprayed out after being guided by the hair care accessory 1.
