Heater for vaporizer device with air preheating element and method for producing the same

Abstract

A heater for a vaporizer with air preheating element includes a casing, a tunnel with a perforated bottom, which is a cylindrical heating chamber for placing a cigarette, a heating element of a resistive type, a heat exchanger, including air channels for circulation and preheating of air by a heater, a top end and a bottom end, an air intake hole made in the top end. Outlet holes are communicated with exits of air channels of the heat exchanger for intake of air preheated by the heater in the tunnel. The casing is made in the form of a tape of a thin-film dielectric heat-resistant material, on which a thin layer of resistive material with contacts is applied on the end of one side, forming the heating element, and on the other side a top and bottom spacers are fixed and inclined toward the middle, as well as the edging, which are made of flexible heat-resistant material. The above mentioned tape with a heating element, located on its external side, is rolled into a cylinder and forms a tunnel, and is additionally coiled into several interconnected spiral coils, and forms a spiral casing with the top and bottom ends so that the top and bottom spacers and the edging located on the inside form a spiral heat exchanger comprising the top and bottom and the middle spiral air ducts for spiral and labyrinth circulation and preheating of air, and at the bottom there is an additional inlet hole for air intake.
