Heating element, atomization head, atomizer and electronic cigarette

Abstract

The invention provides a heating element for an electronic cigarette. The heating element is composed of two or more stacked heating sheets with through holes and/or through slots. A clearance between every two heating sheets is a capillary clearance, and the through holes and/or through slots of the adjacent heating sheets are at least partially communicated. The invention further provides an atomization head comprising the heating element, an atomizer comprising the atomization head and the electronic cigarette comprising the atomizer. Cigarette liquid is conducted through the capillary clearances between the adjacent heating sheets without liquid conduction cotton or glass fibers, odor is avoided, and the risk that users inhale capillary fibers mixed in smoke is avoided.

Description

technical field [0001] The invention relates to the technical field of electronic cigarettes, in particular to a heating component, an atomizing head, an atomizer and an electronic cigarette. Background technique [0002] At present, the heating components in electronic vaporizers usually use liquid-conducting cotton, glass fiber or liquid-conducting ceramics to conduct smoke liquid. However, at high temperatures, both the fluid guide cotton and the glass fiber are easily burnt, and a small amount of smoke produced after burning will affect the taste of the electronic cigarette. On the other hand, catheter cotton and glass fiber are easy to release capillary fibers, and these capillary fibers may be mixed in the smoke and inhaled into the human body, causing harm to the user's body. In the preparation process of liquid-conducting ceramics, a pore-forming agent is usually used to create pores, and the residual pore-forming agent may precipitate harmful substances at high tem...
