Electronic cigarette with dual-chamber dual-air-passage atomizer

Abstract

The invention discloses an electronic cigarette with a dual-chamber dual-air-passage atomizer. The electronic cigarette includes the detachable atomizer and a battery rod; the atomizer includes a shell, an atomization device and a bottom cover, one side of the interior of the shell is provided with a division part which divides an inner cavity of the shell into a large cavity and a small cavity, the upper portion of the atomization device is sleeved with the large cavity, the lower portion of the atomization device is sleeved with the inner wall of the lower edge of the shell, and a first airoutlet pipe, an air outlet through hole and a second air outlet pipe are sequentially connected to form a suction sensing air passage, wherein the small cavity is provided with the first air outlet pipe, the air outlet through hole is formed in the atomization device, and the battery rod is provided with the second air outlet pipe; an air inlet, an air inlet passage, an air inlet cavity, an atomization cavity, a smoke tube and a smoke outlet which are arranged inside the shell are sequentially communicated to form a smoking air passage. The electronic cigarette with the dual-chamber dual-air-passage atomizer has the advantages that the smoking air passage is arranged in the atomizer, and the smoking air passage does not pass through the battery rod, so that parts in the battery rod are prevented from being eroded by water vapor; at the same time, the suction sensing air passage is arranged and is communicated with the position where a battery-rod suction sensor is located, so that it is convenient to achieve automatic smoking control over the electronic cigarette by sensing the magnitude of suction.

Description

technical field [0001] The invention relates to the technical field of electronic cigarettes, and more specifically, the invention relates to an electronic cigarette with a double-cavity and double-airway atomizer. Background technique [0002] A detachable electronic cigarette generally includes an atomizer and a battery rod. The atomizer is provided with a liquid storage chamber to store the electronic cigarette liquid, and is also equipped with an atomizing device to heat and atomize the electronic cigarette liquid. [0003] Chinese patent application document CN106690425A discloses a waterproof electronic cigarette, the electronic cigarette includes a detachably connected atomizer and a battery rod, the atomizer includes a housing and an atomizing device, and a liquid storage chamber is provided in the atomizer And the liquid suction chamber, the shell is provided with a smoke pipe and an air inlet, the atomization device is provided with an air inlet connected with the ...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned electronic cigarette avoids the backflow of smoke into the battery rod, its disadvantage is that all the airflow circulates in the atomizer without passing through the battery rod, and the electronic cigarette with an automatic control circuit must be equipped with a trigger control system
