This application claims priority to Chinese Patent Application No. 202110491502.9 filed May 6, 2021, the disclosure of which is incorporated herein by reference in its entirety.
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.
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 disclosure provides an atomizer for an electronic cigarette. The atomizer for an electronic cigarette can improve the taste and prevent discomfort caused by sucking leaked electronic cigarette liquid.
The present disclosure adopts the solution below.

The present embodiments provide an atomizer for an electronic cigarette. As shown in
Two ends of the intake passage communicate with the suction nozzle opening 311 and the communication hole 321 respectively. During inhalation, an inspiratory airflow passes through the communication hole 321, the intake passage and the suction nozzle opening 311 successively and then enters the mouth of a user. In the atomization cavity 111, the atomizer assembly 2 atomizes electronic cigarette liquid. When there is no external force, the atomized electronic cigarette liquid remains inside the atomization cavity 111. During inhalation, a side of the opening 112 facing the suction nozzle opening 311 forms a negative pressure such that the atomized electronic cigarette liquid inside the atomization cavity 111 can flow through the opening 112, mix with the inspiratory airflow and then enter the mouth of the user through the suction nozzle opening 311. The atomized electronic cigarette liquid inside the atomization cavity 111 only 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 hole 321 and is disposed apart from the atomization cavity 111 through the through groove 113 such that the smoke passage and the intake passage are disposed apart from each other. The inspiratory airflow converges at the suction nozzle opening 311 through the intake passage and directly enters the mouth of the user without passing through the atomization cavity 111 so that the inspiratory airflow is prevented from driving the large-particle smoke inside the atomization cavity 111 to 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 hole 321 of 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.
