Opposing ends of the first and second stem bodies are respectively provided with matched first and second insertion members making the first and second stem bodies be stably connected with each other. Herein, a side wall of the first insertion member is provided circumferentially with a locking member of which a protrusion end is arc-shaped, while a side wall of the second insertion member is correspondingly provided with a locking groove engaged with the locking member such that the locking member is inserted therein. The locking member is provided on the first stem body and the corresponding locking groove is provided on the second stem body, thus realizing secure connection between the first and second stem bodies, making the structure simple, bringing out convenience in assembling and disassembling process and high stability. ## Claims ### Claim 1 An electronic cigarette comprising connected first and second bodies; opposing ends of the first and second stem bodies are respectively provided with a matched first and second insertion members making the first and second stem bodies be stably connected with each other; a side wall of the first insertion member is provided circumferentially with a locking member of which a protrusion end is arc-shaped, while a side wall of the second insertion member is correspondingly provided with a locking groove engaged with the locking member such that the locking member is inserted therein. ### Claim 2 (depends on 1) The electronic cigarette as recited in claim 1, wherein the locking member is a plurality of spherical bodies circumferentially and evenly arranged on the first insertion member; a locating hole is defined in the side wall of the first insertion member; the locating hole passes through the side wall of the first insertion member and its outer diameter is smaller than diameter of the locking member so as to receive the locking member therein and let one end of the locking member to be extended out. ### Claim 3 (depends on 2) The electronic cigarette as recited in claim 2, wherein one side of the locking member adjacent the locating hole is provided with a resilient pressing member for resiliently pressing the locking member inside the locating hole. ### Claim 4 (depends on 2) The electronic cigarette as recited in claim 2, wherein a holding groove is defined in the first insertion member for insertion of a corresponding end of the second insertion member therein; one end of the second insertion member inserted into the first insertion member is provided with a boss conformed to the internal contour of the holding groove so as to be locked into the holding groove. ### Claim 5 (depends on 2) The electronic cigarette as recited in claim 2, wherein an atomization device is disposed in the first stem body; the atomization device includes an atomization base pressed against the first insertion member and an electric heater coil secured on the atomization base; and the atomization base is made of rubber material. ### Claim 6 (depends on 5) The electronic cigarette as recited in claim 5, wherein the width of the side wall, on which the locking member is disposed, of the first insertion member is smaller than the diameter of the locking member; and the atomization base extends toward the first insertion member so as to form a pressing member pressed against the internal opening of the locating hole in order to press the locking member inside the locating hole. ### Claim 7 (depends on 5) The electronic cigarette as recited in claim 5, wherein the battery is disposed in the second stem body; one end of the first stem body opposing to the second stem body is further provided with a first electrode component which will electrically connect the atomization device and battery when the first and second stem bodies are connected with each other; and the first electrode component includes a first electrode member and a second electrode member which are insulated from each other and connected respectively with two ends of the electric heater coil so as to form a positive and negative electrodes of the atomization device. ### Claim 8 (depends on 7) The electronic cigarette as recited in claim 7, wherein the first electrode member is pressed against the atomization base and a first end of the electric heater coil is sandwiched between the two; and the second electrode member is pressed against the atomization base and a second end of the electric heater coil is sandwiched between two. ### Claim 9 (depends on 8) The electronic cigarette as recited in claim 8, wherein the first insertion member is made of conductive material and constitutes the first electrode member. ### Claim 10 (depends on 9) The electronic cigarette as recited in claim 9, wherein a guiding hole is defined in a middle portion of the first insertion member and axially extends through the first insertion member; the middle portion of the atomization base extends to the first guiding hole so as to form an insulation portion; a second guiding hole is axially defined in the insulation portion and extends the atomization base; and the second electrode member passes through the second guiding hole and is insulated from the first insertion member by the insulation portion. ### Claim 11 (depends on 7) The electronic cigarette as recited in claim 7, wherein the battery is a rechargeable battery and another end of the second stem body far away from the first stem body is provided with a charging unit connected to the battery so as to charge the battery. ### Claim 12 (depends on 11) The electronic cigarette as recited in claim 11, wherein the charging unit includes a charging coupler for connecting with an external power source; and the charging coupler is connected to the battery by a charging control module. ### Claim 13 (depends on 7) The electronic cigarette as recited in claim 7, wherein the second stem body is further provided with an atomization control unit electrically connected to the battery so as to supply power to or cut off power from the atomization device; the atomization control unit is disposed between the atomization base and battery; alternatively, the atomization control unit is disposed on the battery at one side away from the atomization base. ### Claim 14 (depends on 13) The electronic cigarette as recited in claim 13, wherein the atomization control unit includes an atomization control circuit and an atomization control switch associated with the atomization control circuit;
