Abstract

The invention discloses a micro-channel electronic cigarette atomization chip and a preparation method thereof. The micro-channel electronic cigarette atomization chip comprises a silicon substrate (1) and a glass cover (4). A microcolumn (2) array or a micropore (3) array, an inlet end (10) and an outlet end (11) are arranged on the silicon substrate (1), a plurality of micro-channels (9) are defined by the microcolumn (2) array, or a smoke liquid channel penetrating through micropores (3) is arranged on the silicon substrate (1). Air holes (5) penetrating through the glass cover (4) are formed in the glass cover (4). The glass cover (4) and the silicon substrate (1) are fixedly connected through a bonding process. According to the micro-channel electronic cigarette atomization chip and the preparation method thereof, silicon is adopted as a base material of the atomization chip, the cost is low, the manufacturing cost of the electronic cigarette atomization chip is greatly reduced, and the atomization chip of this type can be produced on a large scale.

Description

technical field [0001] The invention belongs to the technical field of electronic cigarettes, and in particular relates to a microchannel 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 or linear hea...
