Hair styler and temperature-influencing device

Abstract

A hair styler includes a top cover, a roller body, and a base. The top cover includes a funnel body with a wide mouth and a narrow neck, and formed of a flexible material so as to be pliable or restorable in response to an external force, wherein the funnel body radially includes a plurality of segments, which are different in at least one parameter. The roller body has a first end connected to the narrow neck of the top cover for winding therearound a hair portion, wherein the top cover is flipped over by the external force to confine the hair portion within a space between the top cover and the roller body. The base is connected to a second end of the roller body, which is opposite to the first end, and functions as a flange of the roller body to stop the hair portion from escaping from the space.

         7 . The hair styler according to  claim 1 , wherein the top cover has a first gripping structure on outer and inner surfaces of the funnel body to provide additional friction for hand to operate and flip the funnel body, and for securing hair when the top cover is flipped over hair around the roller body. 
     
     
         8 . The hair styler according to  claim 1 , further comprising a temperature retaining structure inside the roller body for making a thermal and/or cold effect work longer. 
     
     
         9 . The hair styler according to  claim 8 , wherein the roller body is hollow, and the temperature retaining structure is a metal plate disposed inside the roller body. 
     
     
         10 . The hair styler according to  claim 8 , wherein the roller body is hollow, and the temperature retaining structure is a coil spring disposed inside the roller body. 
     
     
         11 . The hair styler according to  claim 10 , wherein the coil spring has a higher coil density at the middle of the roller body, such that heat is gradually cooler wear the top cover and the base when a heat source is applied. 
     
     
         12 . The hair styler according to  claim 10 , wherein the coil spring is disposed and confined in the middle of the roller body by way of stoppers disposed inside the hollow hair roller, and at least one cooling air layer is reserved at either or both of the first and second ends of the roller body. 
     
     
         13 . The hair styler according to  claim 10 , wherein the roller body is hollow, the coil spring is wrapped around a heat-conductive pillar, and inserted into the roller body. 
     
     
         14 . The hair styler according to  claim 1 , wherein the roller body has a second gripping structure on an outer surface thereof to secure hair while hair is wrapped around the roller body. 
     
     
         15 . The hair styler according to  claim 1 , wherein the gripping structure includes ring like tracks or spiral like tracks around an outer surface of the roller tube, and mini teeth and/or dot, and the mini teeth have different lengths and/or thicknesses to provide detangling for hair. 
     
     
         16 . The hair styler according to  claim 1 , wherein the base has an opening, through which a heat and/or cold source can be supplied to the temperature retaining structure inside the roller body. 
     
     
         17 . The hair styler according to  claim 1 , wherein a bottom surface of the base has a third gripping structure to prevent the hair styler from slipping off hair easily, and/or an upper surface of the base has a fourth gripping structure to further secure hair within the space. 
     
     
         18 . The hair styler according to  claim 1 , formed of a material mixed with powders, whose color is changeable with temperature.
