Description

    FIELD OF THE INVENTION
  • The present invention relates to electronic atomization device and, in particular, it concerns an electronic atomization device with an adjustable air inlet.
  • BACKGROUND OF THE INVENTION
  • Electronic atomization device, also called electronic cigarette, atomization tobacco with low temperature, is mainly used for reducing harms brought by smoking traditional cigarette. Its appearance and taste are similar to cigarette and it has more flavors than even normal cigarette does. It can also create a cloud, a taste and a feel that resemble cigarette. The electronic atomization device, which is composed of battery assembly and atomizer, is an imitative cigarette, and flavor components therein can be atomized into gas by atomization so that user can inhale it directly. The flavor components include tobacco liquid, tobacco shred, tobacco powder, tobacco paste, fragrant slice, fragrant bar, liquid tobacco and so on.
  • The atomization device for atomizing the flavor components generally includes an air inlet for inhaling the outside air which will be mixed with the atomizing gas, and such an air inlet may be an access for the condensate and liquid flavor flowing to the outside world. Generally, the air inlet is arranged at the bottom of the electronic atomization device and cannot be closed when not in use, thus the condensate and liquid flavor are very easy to flow to the outside surface of the electronic atomization device which will cause the outside surface of the electronic atomization device to be dirty. And if the condensate and liquid flavor enter into the inside of the battery assembly via the air inlet, the battery assembly may be damaged.
  • SUMMARY OF THE INVENTION
  • An object of the present invention is to overcome the defects of the prior art by providing an electronic atomization device with an adjustable air inlet, which can prevent the condensate and liquid flavor from flowing out of the electronic atomization device via the air inlet, so as to avoid the outside surface of the electronic atomization device getting dirty and reducing the possibility of damaging the battery assembly.
  • To achieve the above object, the following technical solutions are provided:
  • There is provided an electronic atomization device with an adjustable air inlet, which includes a cigarette holder, an atomizer connected to the cigarette holder and a battery assembly for supplying power to the atomizer. The device further includes an air inlet disposed at an upper portion of the atomizer for connecting the atomizer to outside world and a switch assembly disposed between the atomizer and the cigarette holder for opening or closing the air inlet.
  • Preferably, the switch assembly includes a round ring sandwiched between the atomizer and the cigarette holder and a sealing block fixed inside the round ring for opening or closing the air inlet, the round ring being coaxial with the atomizer, and when the round ring rotates with respect to the atomizer, the air inlet will be opened or closed by the sealing block which is driven by the round ring.
  • Preferably, there is provided a flange disposed inside the round ring and the sealing block is fixed on the flange.
  • Preferably, there are provided a limiting notch formed at the flange and a limiting pillar disposed at the top of the atomizer and extending throughout the limiting notch. Due to the assembly relation between the limiting notch and the limiting pillar, the rotation range of round ring will be restricted, thereby avoiding the sealing block far away from the air inlet which will bring inconvenience to use.
  • Preferably, the round ring has an inlet notch formed at the bottom thereof and the air inlet connects to the outside world via the inlet notch.
  • Preferably, the round ring has ant-slip strips formed on an outside surface thereof.
  • Preferably, the sealing block is an elastic sealing block.

  • Preferably, the smoke outlets are disposed at an upper portion of the cigarette holder uniformly. Such a structure will cause that the smokes fill the mouth of user more quickly and easily when using the electronic cigarette. Additionally, it will increase the distance the smokes have to travel in the cigarette holder, thereby lowering the temperature of smokes in the cigarette holder and then improving the taste of the electronic cigarette.
  • Preferably, an upper portion of the cigarette holder has an elliptical or round cross section. Such an elliptical cross section of the cigarette holder can better meet the requirement of human body engineering, thereby improving the user experience.
