Description

Technical Field

[0001] The utility model relates to the technical field of hair beauty instruments, in particular to a detachable power cord structure applied to hair beauty instruments. Background Art

[0002] In the hair beauty industry, hair beauty instruments such as straighteners, curling irons, hair dryers, etc. have become indispensable tools; the power cord connectors of traditional hair beauty instruments are usually connected to the instrument body in a fixed connection manner; this fixed connection power cord connector structure has many problems; first of all, since the length of the power cord is fixed and non-detachable, during use and storage, the too long power cord is easy to tangle and knot, which not only affects the appearance, but also brings inconvenience to the user and increases the difficulty of storage. For example, in a hair beauty salon, the power cords of many hair beauty instruments are tangled with each other, which will affect the work efficiency and the cleanliness of the work environment; secondly, when the power cord is damaged, such as the outer skin is worn or the internal circuit is open, since the power cord connector is fixedly connected to the instrument body, the repair and replacement become very difficult; often, the entire hair beauty instrument needs to be sent back to the manufacturer or a professional repair agency for repair, which not only has a high repair cost, but also delays the use of the user and brings great inconvenience to the user. In addition, for users who often need to travel on business or travel, the fixed and non-detachable power cord connector makes it very inconvenient to carry the hair beauty instrument and increases the burden of traveling.

[0003] Therefore, in order to meet the user's requirements for convenience and flexibility in use, the detachable power cord structure of hair beauty instruments has gradually received attention and research. A hair beauty tool described in Patent 202122142997.2 also adopts a detachable power cord design. However, this locking method is to drive the first guiding block 431 by rotating the rotating sleeve 43, so as to drive the locking block 421 to snap into the locking groove 32. When using this setting method, since the entire rotating sleeve component can rotate, it is easy to accidentally rotate the rotating sleeve to cause an unlocking operation, and there is no restriction structure on the rotating sleeve to restrict its rotation angle. When rotating the rotating sleeve, it is easy to cause excessive friction between the guiding block and the locking rod due to too large a rotation force, or the looseness of the clamping position due to insufficient rotation angle. To sum up, the existing detachable power cord connector structure has certain deficiencies in service life and connection firmness and reliability. In this regard, it is necessary to propose a new technical solution to solve the above problems. Summary of the Utility Model
