Description

Technical Field

[0001] This utility model relates to the field of hair styling device technology, and in particular to a handle structure and hair styling device. Background Technology

[0002] In related technologies, hair styling devices include a handle and accessories mounted on the handle; the handle has a housing, in which a heating element, a motor assembly, and a control unit are installed, and the motor assembly can draw external air into the handle housing to provide airflow for the accessories.

[0003] For handle housings, the upper and lower housings are usually snapped together to complete the assembly of a handle housing. However, when assembling the upper and lower housings by snapping them together, corresponding snapping positions need to be set on the upper and lower housings. However, the setting of snapping positions will increase the wall thickness of the upper and lower housings, making the overall diameter of the handle larger. This will cause inconvenience for users with smaller hands.

[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a handle structure that effectively solves the technical defect that the handle structure of hair styling devices in the prior art has an overall large diameter, so as to facilitate the user's grip.

When the heating frame cover 13 is inserted into the installation chamber, the first fastening positions and the second fastening positions engage with each other.

[0045] Specifically, compared with the prior art, by setting a first fastening position on the upper shell 11 and the lower shell 12, and setting a second fastening position on the heating frame cover 13; when the heating frame cover 13 is installed into the installation chamber, the first fastening position can be fastened to the second fastening position to complete the assembly of the heating frame cover 13, the upper shell 11 and the lower shell 12.

[0046] On the one hand, by setting the second fastening position on the heating frame cover 13, the problem of increasing the wall thickness of the upper shell 11 and the lower shell 12 due to the setting of the fastening position when the upper shell 11 and the lower shell 12 are fastened together in the conventional technology is solved. When assembling the heating frame cover 13 of the same size, the wall thickness of the upper shell 11 and the lower shell 12 can be further reduced, thereby making the overall diameter of the handle smaller, so that the user can hold it.

[0047] On the other hand, by setting the second fastener on the heating frame cover 13, the stress borne by the shell can be dispersed, and the stress can be avoided from being concentrated on the upper shell 11 and the lower shell 12 itself. This allows for a further reduction in the required wall thickness of the upper shell 11 and the lower shell 12, without having to increase the wall thickness of the upper shell 11 and the lower shell 12 to maintain strength.

[0048] Please refer to the following: Figures 3 to 8 In some embodiments of this application, the first fastener is located on the inner bottom sides of both ends of the upper housing 11 and on the inner top sides of both ends of the lower housing 12, and the second fastener is located on the left and right sides of the heating frame cover 13.
