TECHNICAL FIELD

The present disclosure relates to the technical field of electronic cigarettes and, in particular, to an atomizer for an electronic cigarette and an electronic cigarette.

BACKGROUND

In the related art, the atomizer and electronic cigarette liquid storage structure of an electronic cigarette are an integrated structure. The atomizer can atomize electronic cigarette liquid to form smoke. One end of the electronic cigarette is an air inlet communicating with the outside air and the other end of the electronic cigarette communicates with a nozzle. When a user inhales through the nozzle, the outside air enters the atomizer and the electronic cigarette liquid storage structure through an inspiratory airflow. As a result, the smoke enters the nozzle together with the inspiratory airflow. However, the electronic cigarette in use has the following defects: One is that there is large-particle smoke after the atomizer atomizes the electronic cigarette liquid. The large-particle smoke enters the mouth of the user together with the inspiratory airflow, leaving a bad taste of the electronic cigarette and even a scald in the mouth of the user in a severe case. The other is that during the transportation of the electronic cigarette or when the user carries the electronic cigarette to move, the electronic cigarette liquid inside the electronic cigarette liquid storage structure seeps out of the atomizer or leaks from the atomizer. Since the air inlet communicates with the outside air, the user is likely to suck the electronic cigarette liquid when the user mistakes the air inlet of the electronic cigarette as the nozzle.

The present embodiments provide an atomizer for an electronic cigarette. As shown in

FIGS. 1 to 4, the atomizer for an electronic cigarette includes an atomization compartment housing1, an atomizer assembly2and an outer cover3covering the atomization compartment housing1. The outer cover3is provided with a suction nozzle opening311and a communication hole321communicating with the suction nozzle opening311. The atomization compartment housing1includes an atomization cavity111, an opening112and a through groove113. In an embodiment, the atomization cavity111is disposed inside the atomization compartment housing1and the atomizer assembly2is disposed inside the atomization cavity111. The opening112is disposed at an end of the atomization compartment housing1and communicates with the atomization cavity111. The opening112and the atomization cavity111form a smoke passage that communicates with the suction nozzle opening311. A side of the opening112facing the suction nozzle opening311can form a negative pressure such that atomized electronic cigarette liquid can flow through the opening112. The through groove113is disposed in an outer wall of the atomization compartment housing1. The through groove113and the outer cover3form an intake passage. Two ends of the intake passage communicate with the suction nozzle opening311and the communication hole321respectively.

Two ends of the intake passage communicate with the suction nozzle opening311and the communication hole321respectively. During inhalation, an inspiratory airflow passes through the communication hole321, the intake passage and the suction nozzle opening311successively and then enters the mouth of a user. In the atomization cavity111, the atomizer assembly2atomizes electronic cigarette liquid. When there is no external force, the atomized electronic cigarette liquid remains inside the atomization cavity111. During inhalation, a side of the opening112facing the suction nozzle opening311forms a negative pressure such that the atomized electronic cigarette liquid inside the atomization cavity111can flow through the opening112, mix with the inspiratory airflow and then enter the mouth of the user through the suction nozzle opening311. The atomized electronic cigarette liquid inside the atomization cavity111only overflows when the inspiratory airflow forms a negative pressure so that the electronic cigarette liquid leakage is prevented. At the same time, since the smoke passage does not directly communicate with the communication hole321and is disposed apart from the atomization cavity111through the through groove113such that the smoke passage and the intake passage are disposed apart from each other. The inspiratory airflow converges at the suction nozzle opening311through the intake passage and directly enters the mouth of the user without passing through the atomization cavity111so that the inspiratory airflow is prevented from driving the large-particle smoke inside the atomization cavity111to be inhaled into the mouth of the user, and thus the taste can be improved. Moreover, the electronic cigarette liquid can only overflow from one end of the nozzle, so even though the user mistakes one end of the communication hole321of the electronic cigarette for intake as the nozzle, the possibility that electronic cigarette liquid is inhaled into the mouth of the user can be reduced, and thus discomfort of the respiratory tract caused by sucking electronic cigarette liquid can be prevented.
