Atomizer and electronic cigarette

An atomizer, comprising:

• a shell defining a smoke outlet communicating with environment outside of the shell, a liquid cavity for storing a fluid to be vaporized, and an atomizing chamber;
• and
• a heating assembly separating the liquid cavity and the smoke outlet from the atomizing chamber, and comprising:
• a cover being an integral structure, and defining a liquid tunnel, a smoke tunnel and an accommodating space;
• the cover comprising a first side surface and a second side surface opposite to the first side surface;
• a liquid guiding member partially received in the accommodating space, wherein an upper surface of the liquid guiding member abuts the cover, and a side surface of the liquid guiding member is at least partially exposed in the atomizing chamber;
• and
• a heating component arranged on the liquid guiding member and configured to heat the liquid guiding member;
• wherein the liquid tunnel extends from an upper surface of the cover to the accommodating space, and configured to guide the fluid from the liquid cavity to an upper surface of the liquid guiding member;
• the smoke tunnel is opened from an upper surface of the cover, extends through the first side surface and the second side surface, and interconnects the smoke outlet and the atomizing chamber;
• the liquid guiding member is configured to transport the fluid from the liquid tunnel to the atomizing chamber, and to heat the fluid to generate smoke in the atomizing chamber.

An electronic cigarette, comprising an atomizer and a battery assembly connected together, wherein the atomizer comprises:

• a shell defining a smoke outlet communicating with environment outside of the shell, a liquid cavity for storing a fluid to be vaporized, and an atomizing chamber;
• and
• a heating assembly separating the smoke outlet and the liquid cavity from the atomizing chamber, and comprising a liquid guiding member, a cover and a heating component;
• wherein the cover is an integral structure defining a liquid tunnel and a smoke tunnel, the liquid tunnel communicates with the liquid cavity and extends to the liquid guiding member;
• the liquid guiding member is configured to transport the fluid from the liquid tunnel to the atomizing chamber, and to heat the fluid to generate smoke in the atomizing chamber;
• the smoke outlet communicates with the atomizing chamber via the smoke tunnel, such that the generated smoke is allowed to exit from the smoke tunnel and further enter the smoke outlet;
• and
• the heating component is connected with the liquid guiding member, and is configured to heat the liquid guiding member.
