Hair styling device

Abstract

A hair styling device dry and/or to form a hair strand into a curl by suctioning hair into a hair styling chamber is disclosed. The device has a main styling chamber and air flow channel parallel to the styling chamber. The device has a vacuum impeller mounted in a fan chamber. The fan chamber is aerodynamically connected to the main styling chamber and to the air flow channel. The styling chamber has a styling form, which in the depicted embodiment is a spiral for forming spiral curls. The styling form can be heated directly by a heater and the air flow channel can have heating elements to heat the air flowing through it. At the opposite end of the body from the impeller, there is a hair inlet with a mixing tip through which hair is drawn into the styling chamber around the styling form by suction of the air flow.

         4 . The hair styling device of claim wherein the intake channel has a smaller internal diameter than the hair styling chamber. 
     
     
         5 . The hair styling device of  claim 1  further comprising the hair styling chamber having a style form, said style form extending the length of the hair styling chamber and the combined air flow pulling the lock of hair around the style form forming the lock of hair into a spiral; 
     
     
         6 . The hair styling device of  claim 1  further comprising a heating element in the air flow channel to heat the second air flow. 
     
     
         7 . The hair styling device of  claim 1  further comprising the style form being heated. 
     
     
         8 . The hair styling device of  claim 1  wherein a portion of the air flow generated by the impeller is vented to outside of the body without being circulated through the air intake channel. 
     
     
         9 . The hair styling device of  claim 5  wherein the style form is removable and is held in the style chamber by a removal cap. 
     
     
         10 . The hair styling device of  claim 5  wherein the style form is held in the style chamber by a latch located near the fan chamber. 
     
     
         11 . The hair styling device of  claim 1  wherein there is a filter located between the hair styling chamber and the fan chamber to prevent hair or other matter from being drawn into the means to induce an airflow. 
     
     
         12 . A hair styling device comprising:
 a first chamber defining an air flow path from a first end to a second end,   a second chamber having a first end and a second end, said second chamber defining a respective flow path,   a blower having an input and an output, the input of the blower coupled with the second end of the first chamber,   the output of the blower connected with the first end of the second chamber and with an exit port,   a mixing tip, the mixing tip having a mouth of a first diameter and a throat of a second diameter, the second diameter smaller than the first diameter,   the throat coupled with the first end of the first chamber, and   the second end of the second chamber coupled with a plurality of openings between the mouth of the mixing tip and the throat of the mixing tip.   
     
     
         13 . The hair styling device of  claim 12  wherein blowing by the blower draws air into the mouth and through the throat into the first chamber. 
     
     
         14 . The hair styling device of  claim 12  further characterized in that blowing by the blower forces air into the second chamber, and through the at least one opening, the air forced through the first opening being entrained with the air drawn into the mouth and through the throat. 
     
     
         15 . The hair styling device of  claim 12  wherein the mouth and throat and at least one opening define a Venturi structure. 
     
     
         16 . The hair styling device of  claim 12  further comprising a heating element in the respective flow path of the second chamber. 
     
     
         17 . The hair styling device of  claim 12  wherein the mixing tip has a number of openings spaced around the throat, said openings aerodynamically connecting the second chamber to the mixing tip. 
     
     
         18 . The hair styling device of  claim 12  wherein the throat has a smaller internal diameter than the first chamber. 
     
     
         19 . The hair styling device of  claim 12  further comprising the first chamber having a style form, said style form extending the length of the first chamber and the combined air flow pulling the lock of hair around the style form forming the lock of hair into a spiral. 
     
     
         20 . The hair styling device of  claim 12  further comprising the style form being heated.
