Coated silicon-based electronic cigarette atomization chip and making method thereof

Abstract

The invention discloses a coated silicon-based electronic cigarette atomization chip and a making method thereof. The chip comprises a silicon substrate (1) and a glass cover (5); the silicon substrate (1) is provided with a microcolumn (2) array or a microhole (3) array, an inlet end (13) and an outlet end (14), the outer side wall of a microcolumn (2) is a coated side wall, the inner wall of a microhole (3) is a coated inner wall, and multiple micro channels (12) are defined by the microcolumn (2) array or a nicotine liquid flow channel (15) which runs through the microhole (3) is formed inthe silicon substrate (1); the glass cover (5) is provided with an air hole (6) which runs through the glass cover (5); the glass cover (5) is fixedly connected with the silicon substrate (1) througha bonding technology. According to the atomization chip, silicon is used as a base material of the atomization chip, the cost of the atomization chip is low, the cost of manufacturing the electronic cigarette atomization chip is greatly lowered, and convenience is provided for large-scale production of the atomization chip of the type.

Description

technical field [0001] The invention belongs to the technical field of electronic cigarettes, and in particular relates to a film-coated silicon-based electronic cigarette chip and a preparation method thereof. Background technique [0002] At present, the heating materials used in electronic cigarettes that are actually used or reported in patents mainly include metals, ceramics, polymers, silicon, etc., and the most commonly used heating wires are made of metal. Among them, electronic cigarettes with non-adjustable temperature use nickel-chromium alloy wire or Kanthal heating wire, which is an alloy containing nickel, chromium, aluminum, iron, etc.; temperature-controlled electronic cigarettes use pure nickel, pure titanium or stainless steel as heating wire. The shape of the heating element is linear, filamentary, sheet, mesh, etc. The e-liquid can be in contact with the surface of the heating element or contact with the inside to be heated and atomized. For filamentary ...
