The vaporizer assembly comprises an outer sleeve, a liquid storage cup, a vaporizer unit and a heat insulation sleeve. An air passage is formed between an exterior longitudinal flat surface of the liquid storage cup and the heat insulation sleeve. The liquid storage cup is sheathed with the outer sleeve, an inner wall of the outer sleeve and an exterior arc surface of the liquid storage cup forms an arc-shaped slit. An inner wall of the outer sleeve and the exterior longitudinal flat surface of the liquid storage cup forms a vapor flow passage. The vapor flow passage is interconnected to the arc-shaped slit. The mouthpiece assembly is fixed to one end of the outer sleeve to seal an outlet of the arc-shaped slit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Cotton-free electronic cigarette preventing liquid spill","description":"Disclosed is a cotton-free electronic cigarette preventing liquid spill, comprising a vaporizer assembly, a mouthpiece assembly and a battery control assembly.
