In the present embodiment, the electronic cigarette 100 can comprise a cylindrical shell 110, an atomizing component, a mainboard module 120 and a bottom cover 140 with an inner concaved surface. The atomizing component is electrically connected with the mainboard module 120, both of them are provided inside the cylindrical shell 110, the bottom cover 140 is disposed to cover one end of the cylindrical shell 110, the bottom cover 140 is provided with a touch medium on the inner concaved surface, and the touch medium is connected with a touch management chip in the mainboard module 120 to generate a touch control signal.

It can be understood that the cylindrical shell 110 comprises two open ends, and the devices such as the atomizing component and the mainboard module 120 can be mounted inside the cylindrical shell 110 by the open ends. One of the two open ends is used as a smoke outlet or called a suction nozzle, and the other open end is covered by the bottom cover 140. That is, the bottom cover 140 is disposed to cover the end of the cylindrical shell 110 distal from the smoke outlet so as to seal off the cylindrical shell 110.

The shape of the bottom cover 140 is matched with the shape of the cylindrical shell 110. For example, if the cylindrical shell 110 is a columnar barrel with an elliptical radial section, and then the bottom cover 140 can be an elliptical cover, as shown in FIG. 3. If the cylindrical shell 110 is a cylindrical barrel, the bottom cover 140 can be a circular cover. If the cylindrical shell 110 is a prismatic barrel, the bottom cover 140 can correspondingly be a polygonal bottom cover 140. For example, if the cylindrical shell 110 is a quadrangular barrel, the bottom cover 140 can be a quadrangular bottom cover 140.

The shape and size of the inner concaved surface of the bottom cover 140 can be disposed according to actual circumstances, wherein the size of the inner concaved surface is smaller than the outer surface of the bottom of the bottom cover 140.

Exemplarily, referring to FIG. 3 again, the inner concaved surface of the bottom cover 140 can be an elliptical inner concaved surface, the size of the major axis of the elliptical inner concaved surface can be any value in the range of 10mm to 50mm, and the size of the minor axis can be any value in the range of 4mm to 30mm.

Generally, the inner concaved surface is a smooth and concaved camber or curved surface, and the specific shape of the inner concaved surface is not specifically defined herein.

In the present embodiment, the touch control medium can be used as a power switch and a function switch of the electronic cigarette 100, and can change the capacitance value when touched by a user, thereby generating the corresponding touch control signal. The mainboard module 120 can identify the touch control signal and then conduct corresponding functional control according to the touch control signal. For example, the user can touch the touch medium by the touching methods of long touching (long press) , short touching (short press) , consecutive touching (consecutive short press) and the like, so that the touch control medium generates the corresponding touch control signal. The mainboard module 120 can associate various kinds of touch control signals with the corresponding functions in advance, and sequentially implement corresponding control operations when receiving the corresponding touch control signals.

Exemplarily, the mainboard module 120 can use the touch control signal generated when the user's finger touches the touch medium for more than 3 seconds as a control signal for turning on or off the power of the electronic cigarette 100, use the touch signal generated by only touching the touch medium once within 3 seconds as a control signal to control the increasing of the power of the atomizing component, to increase the temperature of the cigarette smoke, and use the touch control signal generated when the touch medium is touched twice within 3 seconds as a control signal to control the decreasing of the power of the atomizing component, to reduce the temperature of the cigarette smoke. It can be understood that controlling the corresponding functions of the electronic cigarette 100 according to different touch control signals is common for a person skilled in the art and will not be repeated here.

In the present embodiment, the atomizing component can be used to receive the cigarette oil, and can heat and atomize the cigarette oil during work, so that the cigarette oil can be diffused as cigarette smoke.

It can be understood that the mainboard module 120 can comprise a main control processor and a touch management chip. The touch management chip can identify and transform the touch control signal generated by the touch medium into the corresponding digital signal, and input the digital signal into the main control processor. The main control processor can identify the digital signal to conduct corresponding function control over the other electronic devices of the electronic cigarette 100. That is, the mainboard module 120 can cooperate with the touch management chip through the main control processor, and identify the long press signal, the short press signal, the double-click or multi-click signal, and multiple gesture signal combinations alternated by long press and short press generated when the user touches the touch medium, so as to achieve different function needs. In the above, the main control processor and the touch management chip are common for a person skilled in the art, and the signal treatment process of the main control processor and the touch management chip is also well known for a person skilled in the art, and will not be repeated here.

The through hole of the bottom cover 140 can be provided in the center portion of the inner concaved surface of the bottom cover 140, as shown in FIG. 3.

For example, the designated region can be ring-shaped, or fan-shaped and the like, and is not defined specifically here.

In the above embodiment, the area of the designated area is smaller than that of the inner concaved surface, so that the touch control medium is located within the inner concaved surface, and in this way, the touch control medium is not easily touched by mistake, and thus the problem can be solved that the electronic cigarette 100 is mistakenly activated due to a mistaken touch.

As an optional embodiment, the atomizing component comprises a cigarette oil chamber 131, a smoke pipe 132 and a heating element 133, and the smoke pipe 132 is provided within the cigarette oil chamber 131, and the heating element 133 is electrically connected with the mainboard module 120 so as to heat and atomize the cigarette oil in the cigarette oil chamber 131.
