Definitions

  • the present invention relates to electronic cigarettes, and particularly to an atomizing head, an atomizer and an electronic cigarette using same.
  • the piercing structure includes a hollow liquid passage. After the piercing structure pricks a liquid supply, tobacco liquid flows to an atomizing cavity through the liquid passage. To prevent liquid leakage, a liquid blocking element is provided at the bottom of the liquid passage. The liquid blocking element is configured for absorbing and storing the tobacco liquid flowed from the liquid passage. However, in the atomizer, the tobacco liquid may leak from the liquid blocking element.
  • EP2260733A1 discloses an atomizing head for an atomizer, according to the preamble of claim 1. Another atomizer is known from EP2489391A1 .
