[0048] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0049] In the description of the present invention, it should be understood that the terms "rise", "fall", "top", "bottom", "inside" and "outside" indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the position or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation of the present invention.

[0050] The utility model aims to provide a straight hair comb capable of cleaning broken hair, which can clean the broken hair remaining in the process of combing hair and improve user experience.

[0051] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0052] See also Figure 1 and Figure 2 The present embodiment provides a hair straightening comb capable of cleaning broken hair, comprising a shell, a lifting bottom plate 200, a lifting aluminum plate 300, a control key 500 and an elastic member 600.

[0054] The lifting aluminum plate 300 is connected to the lifting bottom plate 200 , and the lifting aluminum plate 300 is provided with a plurality of tooth holes 310 extending vertically.

[0055] It should be noted that the number and shape of the tooth holes 310 can be adjusted according to actual conditions and are not specifically limited here.

[0056] The comb tooth assembly is arranged between the lifting aluminum plate 300 and the lifting bottom plate 200. The comb tooth assembly is provided with comb teeth that can be inserted into the tooth holes 310 for combing hair.

[0057] In this embodiment, the bottom of the comb teeth fits in the tooth hole 310, and the shape and structure of the comb teeth should be compatible with the shape and structure of the tooth hole 310 to facilitate the insertion of the comb teeth.

[0058] The control key 500 is attached to the side of the lifting base plate 200 away from the comb teeth assembly, and is used to lift the lifting base plate 200 so that the lifting aluminum plate 300 can clean the broken hair between the comb teeth.

[0059] An elastic member 600 is disposed between the lifting base plate 200 and the comb teeth assembly to restore the lifting base plate 200 driven by the control key 500.

[0060] It is understandable that pressing the control key 500 causes the lifting base plate 200 to rise, at which time the elastic member 600 is in a force storage state. When the control key 500 is released, the elastic member 600 is released to drive the lifting base plate 200 to recover.

[0061] See also Figure 4 and Figure 5 Specifically, the hair straightening comb can play the effect of combing and straightening hair. A comb tooth assembly is provided between the connected lifting aluminum plate 300 and the lifting bottom plate 200, and the comb tooth assembly is provided with comb teeth for combing hair. By pressing the control key 500, the lifting bottom plate 200 can drive the lifting aluminum plate 300 to move along the extension direction of the comb teeth to clean the broken hair between the comb teeth. When the control key 500 is released, the lifting bottom plate 200 drives the lifting aluminum plate 300 to move back together under the action of the elastic member 600.
