This application claims priority to Chinese Utility Model application No. 202321442671.4, filed on Jun. 7, 2023. The disclosure of the application is incorporated herein for all purposes by reference in its entirety.
The present disclosure relates to an accessory of a hair dryer, in particular to an airflow hood of a hair dryer.
When drying curly hair, in order to avoid styling damage and hair damage caused by the hair being close to an overheated hair dryer, a flared airflow hood product is often used.
The airflow hood includes a fixing part fixed to the hair dryer, a flared shell, and an air outlet hole plate fixed at the front end of the shell.
During use, the fixing part is connected to an air outlet of the hair dryer, and then the hair is placed on the air outlet hole plate for drying.
The airflow hood can not only diffuse the hot air, but also keep the hair at a certain distance from the air outlet of the hair dryer to prevent overheating. At the same time, it can blow to most of the hair at one time, which improves the efficiency of drying and care and achieve the purpose of drying and care of hair more safely and efficiently.
However, in the existing airflow hood products, the fixing part is usually designed as a soft silicone sleeve that matches the air outlet of the hair dryer of the corresponding size, due to (1) the soft silicone sleeve is elastic and deformable, thereby easily adapting to the hair dryer outlet, and (2) the frictional properties of the silicone make the silicone soft cover not easy to loosen after it is connected to the hair dryer. However, matching hair dryers of different sizes is difficult. Professional barbershops or individuals staying in hotels often have incompatibility problems when faced with hair dryers of different specifications. In addition, due to the large volume of the airflow hood, it is inconvenient to carry, so it is necessary to improve it.
The purpose of the disclosure is to provide an airflow hood that can be adapted to be connected to hair dryers of different specifications.
In order to achieve the above object, the technical solution adopted in the disclosure is shown as below.

Below in conjunction with accompanying drawings and embodiments, the disclosure is further described:
Referring to
During use, the two corresponding pressing blocks 122 may be radially pressed with one hand, so that the pressing block 122 pushes against the driving ends of the corresponding two clip bodies 1211 at the same time, the clip bodies 1211 then rotate about their respective mounting shaft 1212 such that four clips 121 of the two clamping mechanisms 12 move towards the inner wall of the sleeve 11. The air outlet of the hair dryer may be inserted into the sleeve 11, and then the pressing blocks 122 are released so that the clips 121 are driven by the corresponding torsion springs 1213 to move close to the hair dryer until the four contact plates 1215 hold and clamp the air outlet of the hair dryer. This clamping and fixing arrangement makes the airflow shell 2 applicable to hair dryers of various specifications. During operation, it is only necessary to press or loosen the pressing blocks 122 with one hand to complete the clamping or unclamping, which is convenient for user to use. In addition, the contact plate 1215 is hingedly provided at the clamping end of the clip body 1211, so that the contact plate 1215 may be adaptively configured to form an adjustable clamping angle according to the profile of the air outlet of the hair dryer. Therefore, hair dryers of different specifications may be optimally clamped and fixed.
In some embodiments, the airflow shell 2 is made of flexible silicone, and the airflow shell 2 defines several folding portions 21 at different axial positions, wherein the airflow shell 2 can be folded in the axial direction at the folding portions 21. The flaring airflow shell 2 may be bent, when pressed, at each folding line 21 to realize axial folding, thereby reducing the overall volume, which is convenient to carry.
In some embodiments, the airflow shell 2 includes a first annular shield 201, a second annular shield 202 and a third annular shield 203 whose diameters increase sequentially, and a flaring angle of the second annular shield 202 is larger than a flaring angle of the first annular shield 201 and a flaring angle of the third annular shield 203, so that the airflow shell 2 has a larger diameter for air exiting and can be folded more easily.
In some embodiments, the airflow shell 2 is provided with a first mounting ring 22 extending radially inward at its top, and the first mounting ring 22 is provided with a rigid gasket 23. The sleeve 11 is provided with a second mounting ring 13 extending radially inward at its top, a plurality of support columns 14 are circumferentially arranged on a bottom surface of the second mounting ring 13 and extend against the first mounting ring 22. The airflow shell 2 is fixed to the support columns 14 through screws passing through the gasket 23 and the first mounting ring 22. Some of the support columns 14 may act as the mounting shafts 14 for hinging the clip bodies 1211. On the one hand, the first mounting ring 22 made of flexible silicone material is clamped and fixed between the support columns 14 through the gasket 23, so that the airflow shell 2 can be reliably fixed on the sleeve 11; on the other hand, some of the support columns 14 are also used to hinge the clip bodies 1211, so that the installation the clip bodies 1211 is reliable and simple.
In some embodiments, when the two opposing pressing blocks 122 are radially pressed, both the clip bodies 1211 and the contact plates 1215 are accommodated in an annular space defined by the first mounting ring 22 and the second mounting ring 13. The diameter of the hair dryer that can be clamped by the clamping mechanisms 12 can be maximized.
In some embodiments, the second mounting ring 13 and the pressing block 122 may provide a mutually cooperative sliding structure along the moving direction of the pressing block 122. Specifically, for example, the second mounting ring 13 has a sliding groove 131 extending along a sliding direction, and the pressing block 122 has a sliding block that cooperates with the sliding groove 131, so that the pressing block 122 can move along pressing radial direction, which ensures the reliability of the structure.
In some embodiments, the clip body 1211 has a slot 1211a, at the clamping end, for installing the contact plate 1215, the contact plate 1215 may be hingedly installed within the slot 1211a via the rotating shaft 1214, preferably at the middle of the contact plate 1215. The middle portion of the contact plate 1215 may be hinged to the clip body 1211 such that the contact plate 1215 is capable of swinging with the rotating shaft 1214 as the fulcrum. The slot 1211a is used to make sure that the contact plate 1215 will not touch the clip body 1211 during the swing process.
In some embodiments, the contact plate 1215 includes a rigid back board 1215a, and a flexible silicone plate 1215b fixed on a front side of the back board 1215a to be in contact with the hair dryer. The flexible silicone plate 1215b has a corrugated or toothed surface for preventing sliding at its front side. The contact plate 1215 is in contact with the hair dryer through the flexible silicone plate 1215b, which can avoid damage to the hair dryer during the clamping process. At the same time, the corrugated or toothed surface also increases the friction, making clamping reliable.
In some embodiments, the plate 3 with holes for air exiting has a placement cavity 31 on its inner side. Volatile essential oils, shampoos, and the like can be placed within the placement cavity 31 and spread to the hair with the airflow during the blowing process, so that it can be more evenly combined with the hair and better absorbed by the hair.
In some embodiments, a plurality of protrusions 32 with spherical heads are arranged on an outer side of the plate 3 with holes for air exiting. The protrusions 32 can comb the hair during the drying process, so as to avoid knotted hair.
The above description does not limit the technical scope of the present disclosure. Any modification, equivalent change and modification made to the above embodiments according to the technical essence of the present disclosure still belong to the scope of the technical solution of the present disclosure.
