[0040] Working principles of an electronic cigarette device are described as follows. Since the reception unit 71′ of the wireless charging receiver 7′ is disposed inside the at least one electronic cigarette 100, the reception unit 71′ approaches the transmitting unit 71 to cause the transmitting unit 71 and the reception unit 71′ initiating electromagnetic induction therebetween, and the first electronic switch is triggered for electrical connection by induction electrical currents generated by the transmitting unit 71 when the power rod 91 is inserted into the cigarette case 200. Afterwards, the first circuit processing module controls the transmitter circuit processing unit to transform and tune so as to acquire voltages and electrical currents needed by the transmitting unit 71. The transmitting unit 71 therefore initiates its work to transmit electromagnetic signals. The reception unit 71′ of the at least one electronic cigarette 100 is capable of automatically inducing and receiving electromagnetic signals transmitted from the transmitting unit 71 of the wireless charging transmitter 7, then the receiving conversion circuit disposed on the receiver circuit board 73′ receives the electromagnetic signals and converts the signals into electrical currents, and finally the second rechargeable battery 913 is recharged via the second charging circuit unit. It is convenient to recharge without disassembling the inhaling rod 90 and the power rod 91 during the entire process as above mentioned. When the quantity of electricity of the first rechargeable battery 84 is need to be displayed, it simply needs either insertion of the at least one electronic cigarette 100 or pressing on the key 881 to make the display unit 75 displaying the quantity of electricity of the first rechargeable battery 84.

[0041] Understandably, the at least one electronic cigarettes 100 of this invention can be made as an integrated whole, in other words, the inhaling rod 90 and the sleeve 910 of the power rod 91 are made as an integral casing.

[0042] The above mentioned is only exemplary embodiments of the present invention. It should be noted, for persons of ordinary skill in this art field, improvements and modifications within the spirit and principle of the present invention can be further made, and such improvements and modifications should be seemed to be included in the claimed scope of the present invention.
