Description

The present invention specifically relates to an electronic cigarette atomizer and this electronic cigarette.

In the atomizer of the electronic cigarette, the air supply port, the air supply passage, the atomization chamber, the exhaust passage, the exhaust port, and the mouthpiece are sequentially connected. When smoking, air enters the atomization chamber from the air supply port through the air supply passage, is accompanied by smoke in the atomization chamber, and sequentially enters the user's mouth through the exhaust passage, the exhaust port, and the mouthpiece. , Sucked by the user.

In the prior art, it is common for users with different vital capacities to install an airflow control ring at the airflow port and adjust the size of the airflow port with this airflow control ring in order to meet the demand for air flow during smoking. Is. Such an adjustment method 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 easily deformed due to wrinkles, which increases the frictional force and deteriorates the sealing performance. Adjustment is inconvenient. Since the area of the hand-held portion of the airflow adjusting ring is extremely small, it is difficult to hold the airflow adjusting ring, and it is difficult to control the force applied during the adjustment. As a result, it becomes difficult to adjust the desired air supply amount. 2. When smoking, the flow velocity of the airflow in the atomization chamber is constant, so if the tensile force generated by the airflow velocity becomes greater than the adhesive force of the tobacco liquid, the user will eject small particles of liquid droplets. It can be inhaled, degrading the user experience.

The conventional adjustment method for adjusting the air flow rate of an electronic cigarette using an air flow adjustment ring is inconvenient, takes time and time, and has poor sealing performance. An object of the present invention is to cope with the above-mentioned drawbacks of the prior art, that the air flow rate can be adjusted easily and quickly, the user avoids inhaling the cigarette liquid of small granules, the sealing performance is excellent, and the user's experience is improved. To provide an e-cigarette atomizer and this e-cigarette.

The technical proposal adopted by the present invention in order to solve the above technical problems is as follows.

It is characterized by further providing an adjusting means for adjusting the distance between the outlet of the atomized part and the atomized surface of the atomized component.

According to the above structure, the present invention provides a new airflow adjusting method for adjusting the distance between the outlet of the air supply passage and the atomized surface of the atomized component by adjusting means. When atomizing with the atomizing part, the generated smoke is emitted from the surface of the atomizing surface of the atomizing part, so adjust the distance between the outlet of the air supply passage and the atomizing surface of the atomizing part. Thereby, the size of the volume of the intersection region between the air supply passage and the smoke discharge path of the atomizing component can be adjusted, and the gas passage area between the air supply passage and the exhaust passage can be adjusted, and the unit is also. By controlling the amount of air flow or smoke flowing through the atomization chamber per hour, the amount of liquid droplets of small granules blown off by the air flow rate per unit time is controlled, whereby the user inhales the tobacco liquid. It can also be understood to avoid this and meet the needs of users with different lung activity. Furthermore, if the distance between the outlet of the air supply passage and the atomized surface of the atomized parts is adjusted to be small, the airflow flowing out from the outlet of the air supply passage gives a large impact force to the atomized surface of the atomized parts. This impact force affects the distribution of the smoke liquid on the atomization wick that comes into contact with the atomized surface of the atomized part (blowing the tobacco liquid around) and therefore fog even when it is prematurely infiltrated into the liquid. The chemical parts can be atomized normally to generate smoke, and the amount of smoke and the scent of smoke are not impaired.

Has a pin. According to the above structure, the air supply pipe moves steplessly toward the atomized surface of the atomized component by driving the movable member, and the distance between the outlet of the air supply passage and the smoke emitting surface of the atomized component is increased. Decrease.

Further, a repositioning means for repositioning the movable member in a direction away from the atomized surface of the atomized component is further provided.

In the repositioning of the movable member, the drive of the movable member causes the air supply pipe to move steplessly in the direction away from the atomized surface of the atomized component, and the distance between the outlet of the air supply passage and the smoke emitting surface of the atomized component. Increases.

When the user smokes with a large lung activity (lung smoking), the air flow velocity increases and the amount of air supplied per unit time increases, and therefore, the distance from the exhaust end of the air supply pipe to the atomizing wick is increased, and the air supply is increased. Increases the corner area at the junction of the air passage and the exhaust passage, reduces the impact force of the atomized wick on the tobacco liquid due to the air supply airflow, and the liquid droplets of small particles in the atomized wick accompany the high speed airflow. The high-speed airflow carries the smoke atomized by the ultrasonic waves to the user's oral cavity for smoking, thus solving the phenomenon of inhaling the tobacco liquid. At the same time, it meets the smoke volume needs of users.

When the user smokes with small lung activity (oral smoking), the airflow velocity decreases and the amount of air supply per unit time decreases, and therefore the interval from the exhaust end of the air supply pipe to the atomization wick is reduced. Reduces the corner area at the junction of the air supply and exhaust passages, allowing the airflow to pass through the surface of the atomizing wick, accompanied by ultrasonically atomized smoke, and sufficient smoke for the user. It is used for smoking, gives the user comfort by smoking, and also slows down the airflow, so that the small granules resist the adhesive force between the tobacco liquids as the airflow passes through the surface of the atomized wick. The liquid droplets are not blown to the user's oral cavity. Therefore, in the case of oral smoking, the user can avoid inhaling the tobacco liquid, and there is no reduction in smoke, so that the user's needs can be met.

By rotating the mouthpiece, the distance from the exhaust end of the air supply pipe to the atomization wick is increased or decreased, thereby adjusting the amount of air supply or smoke generation, and the user inhales the cigarette liquid. It is possible to reduce the phenomenon that the user can easily and easily switch between the smoking method of oral smoking and lung smoking, satisfy the smoke amount adjustment needs of the user, and put the ultrasonic atomizer into practical use.
