The present disclosure provides an electronic cigarette1000.

Referring toFIG. 1toFIG. 5, the electronic cigarette1000of the present disclosure includes an atomizer100and a power supply assembly200. The power supply assembly200is internally provided with a master control board220which is in electrical connection with an inbuilt power supply210. The atomizer100includes a top cover10, a base30, an atomizing assembly50, and a light-transmitting sleeve70connecting the top cover10and the base30.

The cover body11defines a liquid refill hole1111which is in communication with the liquid storage chamber60and an air inlet chamber1112which is in communication with the atomizing chamber. The aerosol outlet pipe13is at least partially accommodated in the air inlet chamber1112, and the aerosol outlet pipe13has two ends communicated with the mouthpiece12and the atomizing chamber respectively. Exterior air passes through the air inlet chamber1112, the atomizing chamber and the aerosol outlet pipe13in sequence and finally is expelled from the mouthpiece12.

The base30includes a base body31, an electrode assembly32, and a light-emitting assembly33illuminating the liquid storage chamber60. The base body31is fixedly mounted on the power supply assembly200, the electrode assembly32electrically connects the atomizing assembly50to the master control board220, and the light-emitting assembly33is fixedly mounted on the base body31and is electrically connected to the master control board220.

Therefore, a tobacco liquid enters the liquid storage chamber60from the liquid refill hole1111defined on the top cover10, and then permeates into the atomizing chamber from the liquid guide port52defined at the bottom of the liquid storage chamber60. Exterior air enters the atomizing chamber through the air inlet chamber1112defined on the top cover10, and then flows out through the mouthpiece12, mixing with an atomized aerosol, for a user to inhale. The tobacco liquid in the liquid storage chamber60is not easy to leak through the air inlet chamber1112defined on the top cover10of the electronic cigarette1000. Therefore, the sealing performance for the tobacco liquid is improved. Meanwhile, the aerosol outlet pipe13is partially accommodated in the air inlet chamber1112. When a user inhales, exterior cold air enters the air inlet chamber1112and then contacts the aerosol outlet pipe13accommodated in the air inlet chamber1112to be preheated, and then flows into the atomizing chamber for the tobacco liquid to be atomized to form a hot air aerosol, and finally is expelled through the aerosol outlet pipe13. At such time, when the hot air aerosol flows through the aerosol outlet pipe13accommodated in the air inlet chamber1112, the hot air aerosol exchanges heat with cold air to cool down. Therefore, the condition the hot air makes the mouthpiece12hot to burn mouth is effectively avoided. Moreover, the present disclosure illuminates the liquid storage chamber60by arranging the light-emitting assembly33on the base body31. Various lighting effects can be generated during the usage process of the user. The use experience of the user is effectively improved.

Here, in the present embodiment, the mouthpiece12is partially accommodated in the accommodation hole, and the mouthpiece12is provided with threads and is fixedly connected to the moveable cover112, so that a user can replace the mouthpiece conveniently. Meanwhile, occurrences of the mouthpiece12falling off and getting lost can be effectively avoided. Further, the moveable cover112and the fixed cover111are connected through a rotating pin. The rotating pin may have one end fixedly connected to the fixed cover111through interference fit and the other end connected to the moveable cover112through clearance fit, so that the moveable cover112is capable of rotating. The connection pin is capable of extending out the moveable cover112. The portion of the rotating pin extending out the moveable cover112may be provided with a stop block or an adjusting nut, so that the moveable cover112is not easy to separate from the fixed cover111. The arrangement of the adjusting nut also can facilitate the user to adjust the tightness of the rotation of the moveable cover112. Besides the above, during the rotation process, the moveable cover112and the fixed cover111are always connected to each other, so that the moveable cover112is not easy to lose.

Further, as shown inFIG. 1toFIG. 4, in the embodiment of the present disclosure, a sealing pad113is further provided between the fixed cover111and the moveable cover112, the fixed cover111defines an accommodation recess1113configured for accommodating the sealing pad113, the liquid refill hole1111is defined in the accommodation recess1113, the sealing pad113defines an opening (not marked in the drawings) corresponding to the liquid refill hole1111, the moveable cover112abuts against the sealing pad113when covering the liquid refill hole1111. In addition, in the present embodiment, the sealing pad113is made of elastic rubber materials. The elastic effect of the sealing pad113enables a sealing cover and an upper cover to keep an interaction force against each other, thus the sealing cover and the upper cover are not easy to loosen after they abut against each other. Meanwhile, one surface of the sealing pad113facing the moveable cover112is provided with a rib surrounding the liquid refill hole1111, so that, when the moveable cover112covers the accommodation recess1113, the moveable cover112is in interference fit with the rib to tightly abut against the sealing pad113and to tightly seal the liquid refill hole1111. And/or, one of the fixed cover111and the moveable cover112defines a snap-in connection groove1122, and the other one of the fixed cover111and the moveable cover112is provided with a snap-in projection1114; when the snap-in projection1114and the snap-in connection groove1122are in a snap-fit connection, the moveable cover112is tightly locked in the fixed cover111and covers the liquid refill hole1111. Here, in the present embodiment, when the moveable cover112is fastened in the fixed cover111through a snap-fit connection, loosening is not easy to occur.

Here, the regulating ring14can be sleeved on the fixed cover111through thread or clearance and the like structure. The side wall can define a plurality of regulating holes141simultaneously. When the regulating ring14moves by rotation on the periphery of the fixed cover111, overlapping of opening areas is caused between the regulating hole141and the air inlet chamber1112, and air enters from the overlapped opening area, thereby regulating the amount of air input. Since the amount of air input directly influences the volatile effect of the tobacco liquid, rotating the regulating hole141can control the volatile speed of the tobacco liquid, thereby satisfying the use experiences of different users.

Further, as shown inFIG. 1,FIG. 3orFIG. 4, in the embodiment of the present disclosure, the periphery of the moveable cover112is provided with a plurality of bumps which are arranged spaced apart. Here, in the present embodiment, by providing on the periphery of the moveable cover112a plurality of bumps which are arranged spaced apart, when a user rotates the moveable cover112, the friction is effectively enhanced, the occurrence of slipping is avoided and it is convenient for the user to operate. And/or, the periphery of the regulating ring14is provided with a plurality of projections142which are arranged spaced apart. Here, in the present embodiment, by providing on the periphery of the regulating ring14a plurality of projections142which are arranged spaced apart, when a user rotates the regulating ring14, the friction is effectively enhanced, the occurrence of slipping is avoided and it is convenient for the user to operate.

It is understandable that, during practical applications, the manner of enhancing the friction between the moveable cover112or the regulating ring14and a human body is not restricted to the above manner of providing a plurality of projections142or bumps, for example, it can also apply the manner of providing irregular patterns on the peripheries of the moveable cover112and the regulating ring14and other manners of enhancing friction, which are all intended to be included in the scope of protection of the present disclosure.

Here, in the present embodiment, one end of the connection ring15is sleeved on the periphery of the chamber wall of the air inlet chamber1112, and the other end thereof is connected to the atomizing assembly50through thread, meanwhile, the base30and the atomizing assembly50are in thread connection, thus the atomizing assembly50is convenient to disassemble or assemble. Herein, the air generated when the tobacco liquid in the atomizing chamber is atomized passes through the aerosol outlet pipe113penetrating into the air inlet chamber1112, and then reaches the mouthpiece12. A user inhales the aerosol through the mouthpiece12. Exterior air enters the atomization chamber after entering the air inlet chamber1112via the regulating hole141, so that the atomized air in the atomization chamber is not easy to volatile out from the air inlet chamber1112. The utilization and use effect of the tobacco liquid are improved. Moreover, air can be temporarily stored through the air inlet chamber1112and the normal volatilization of the tobacco liquid is guaranteed.
