Description

The present invention particularly relates to electronic cigarette atomizers and electronic cigarettes.

In an electronic cigarette atomizer, an air supply port, an air supply passage, an atomization chamber, an exhaust passage, an exhaust port, and a mouthpiece are sequentially connected. When smoking, air enters the atomization chamber from the air supply port through the air supply passage, entrains the smoke in the atomization chamber, and enters the mouth of the user sequentially through the exhaust passage, the exhaust port and the mouthpiece. , sucked by the user.

In the prior art, it is common to install an airflow adjustment ring on the air inlet, and adjust the size of the air inlet with this airflow adjustment ring, in order to meet the airflow demands of users with different lung capacity when smoking. is. Such an adjustment scheme has the following drawbacks. 1. When the airflow adjustment ring rotates, the seal ring between the airflow adjustment ring and the air supply port is likely to wrinkle and deform, thereby increasing the frictional force and degrading the sealing performance. Inconvenient to adjust. In addition, since the area of the hand-held portion of the airflow adjustment ring is extremely small, it is difficult to hold and control the amount of force required for adjustment. As a result, adjustment to the desired amount of air supply becomes difficult. 2. When smoking, the flow velocity of the air stream in the atomization chamber is constant, so that the drag force generated by the air stream velocity is greater than the sticking force of the tobacco liquid, so that the user can release the liquid droplets of small granules. Can be inhaled, degrading user experience.

The conventional method of adjusting the airflow rate of the electronic cigarette using an airflow adjusting ring is inconvenient, time-consuming, and has poor sealing performance. The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art, so that the airflow can be adjusted easily and quickly, the user can avoid inhaling small granules of tobacco liquid, the sealing performance is excellent, and the user's experience is improved. To provide an electronic cigarette atomizer and this electronic cigarette that can

Adjust the distance between the outlet of the air supply passage and the atomizing surface of the atomizing part, because the smoke generated when atomizing with the atomizing part will be emitted from the surface of the atomizing surface of the atomizing part. By adjusting the volume of the intersection area between the air supply passage and the smoke discharge passage of the atomizing part, the gas passage area between the air supply passage and the exhaust passage can be adjusted, and the unit By controlling the amount of airflow or smoke flowing through the atomization chamber per unit time, the amount of liquid droplets of small granules blown by the airflow per unit time is controlled, so that the user inhales the tobacco liquid. It is also understandable to avoid this and meet the needs of users with different lung capacities. Furthermore, when the distance between the outlet of the air supply passage and the atomizing surface of the atomizing part is adjusted to be small, the airflow flowing out from the outlet of the air supply passage exerts a large impact force on the atomizing surface of the atomizing part. , this impact force affects the distribution of the tobacco liquid at the atomizing wick in contact with the atomizing surface of the atomizing part (blowing the tobacco liquid to the periphery), and therefore, even in the prematurely penetrated state of the liquid, the fog The atomizing part can normally atomize and generate smoke without spoiling the amount of smoke and the feeling of smoking the smoke.
