The utility model relates to a negative ion straight hair comb structure, which mainly comprises an upper clamping body and a lower clamping body, wherein the upper clamping body and the lower clamping body have a shaft hinge at the rear end thereof, and the upper clamping body and the lower clamping body are freely opened and closed by the shaft hinge And a semiconductor heating element is respectively disposed on the upper body and the lower body. Wherein, the lower clip system is provided with a floating protrusion, the release protrusion is provided with an release hole, and the lower clamp body is provided with an negative ion element, and the negative ion element is placed on the floating protrusion； the upper clamp body and the lower part The clip system is respectively provided with comb teeth, and the comb teeth are respectively arranged in a sharp vertex shape with a top edge being sharp and a bottom edge being wide. When using, the upper and lower clips are used to firmly hold the appropriate amount of hair, and the combing action of the hair is combed to straighten and straight straight hair, and the negative ions can be released from the release hole to be sprayed around the comb teeth. It can protect the hair from static electricity, dryness, and breakage of the hair to achieve hair care.一種負離子直髮梳結構，主要係包含上夾體及下夾體，該上夾體及下夾體後端設有軸鉸鏈，藉由軸鉸鏈使該上夾體及下夾體可自由開合，並於該上夾體及下夾體分別設有半導體發熱件。其中，該下夾體係設有一浮突部，於該浮突部設有釋出孔，下夾體內部係設有一負離子元件，該負離子元件係置於該浮突部；該上夾體及下夾體係分別設有梳齒，該等梳齒係分別設為頂緣較尖而底緣較寬之尖椎狀。俾於使用時利用上夾體及下夾體將適量頭髮牢固的夾持，搭配對頭髮的梳理動作，梳理出又直又順的直髮，且可由釋出孔釋出負離子噴到梳齒周邊產生保護作用，從而可避免頭髮產生靜電、乾燥、分岔斷裂，達到護髮之目的。
