Referring to fig. 1 and 2, in an embodiment of the present invention, anelectronic cigarette 100 includes acartridge 10 and a power supply device (not shown) electrically connected to thecartridge 10. Wherein, thecartridge 10 includes acartridge body 11 and an atomizingcore 13. A liquid storage cavity (not shown) for storing tobacco tar is formed in thecartridge body 11, and the atomizingcore 13 is assembled in thecartridge body 11 and is in fluid communication with the liquid storage cavity so as to heat the adsorbed tobacco tar to form smoke under the electric drive of the power supply device for a user to suck.

Thecartridge body 11 includes ahousing 110 and abase 112. Thehousing 110 is substantially hollow, and has a first opening 1101 at one end. Thebase 112 is detachably coupled to an end of thehousing 110 having thefirst opening 1101 and forms the liquid storage chamber with thehousing 110.

The aforementioned detachable mating manner between thehousing 110 and thebase 112 may be that one of thehousing 110 and thebase 112 is provided with a first mating assembly (i.e., at least twofirst mating portions 1103 mentioned below), and the other of thehousing 110 and thebase 112 is provided with a second mating assembly (i.e., at least twosecond mating portions 1121 mentioned below). When the first mating assembly is mated with the second mating assembly, thehousing 110 is fixedly mated with thebase 112; when the first mating assembly is separated from the second mating assembly, thehousing 110 and thebase 112 are detached.

That is, in the present application, thebase 112 is detachably coupled to thehousing 110 through the cooperation of the first coupling assembly and the second coupling assembly, so that the user can assemble and disassemble the atomizingcore 13 conveniently. For example, when the atomizingcore 13 needs to be replaced, the first mating assembly is separated from the second mating assembly, so that thebase 112 is detached from thehousing 110 to complete the replacement of the atomizingcore 13. When the atomizingcore 13 is replaced, the first and second mating assemblies are operated again to mate thebase 112 to thehousing 110, thereby completing the assembly of thecartridge 10.

Specifically, the first mating assembly includes at least onefirst mating portion 1103, and the second mating assembly includes at least onesecond mating portion 1121, when one of thebase 112 and thehousing 110 is rotated relative to the other, eachsecond mating portion 1121 is screwed into thefirst mating portion 1103 adjacent thereto in the rotation direction and is locked in rotation.

Preferably, there are at least twofirst mating portions 1103, and at least twofirst mating portions 1103 are disposed at intervals in the circumferential direction of thecartridge body 11; the number of thesecond mating portions 1121 is at least two, and the at least twosecond mating portions 1121 are disposed at intervals along the circumferential direction of thecartridge body 11.

The above-mentioned "circumferential direction of thecartridge body 11" includes a first circumferential direction and a second circumferential direction which are opposite in direction, that is, at least twofirst mating portions 1103 may be disposed at intervals in the first circumferential direction or the second circumferential direction.

At this time, eachsecond mating portion 1121 can be screwed into the adjacentfirst mating portion 1103 along the first circumferential direction, and is in locked-screwing fit with the currentfirst mating portion 1103, so as to realize the fixed mating of thehousing 110 and thebase 112; and eachsecond mating portion 1121 can also be withdrawn from the currentfirst mating portion 1103 along the second circumferential direction, so as to separate thehousing 110 from thebase 112. Alternatively, eachsecond mating portion 1121 can be screwed into the adjacentfirst mating portion 1103 along the second circumferential direction, and is in locked-screwing fit with the currentfirst mating portion 1103, so as to realize the fixed mating of thehousing 110 and thebase 112; and eachsecond mating portion 1121 can also be withdrawn from the currentfirst mating portion 1103 along the first circumferential direction, so as to separate thehousing 110 from thebase 112. One of the first circumferential direction and the second circumferential direction is clockwise, and the other one is counterclockwise, which is not limited herein.

Further, the above-mentioned "at least twofirst mating portions 1103 are provided at intervals in the circumferential direction of thecartridge body 11" includes the following three arrangements:

the at least two first matchingparts 1103 are arranged on the same circumference at intervals along the circumferential direction of thecartridge body 11, that is, the at least two first matchingparts 1103 are staggered in the circumferential direction of thecartridge body 11;

the at least two first matchingparts 1103 are arranged on different circumferences which are distributed along the axial direction of thecartridge body 11 at intervals along the circumferential direction of thecartridge body 11, namely, the at least two first matchingparts 1103 are staggered in the circumferential direction of thecartridge body 11 and also staggered in the axial direction of thecartridge body 11;

the at least twofirst mating portions 1103 are disposed on different circumferences radially distributed along thecartridge body 11 at intervals along the circumferential direction of thecartridge body 11, that is, the at least twofirst mating portions 1103 are not only staggered in the circumferential direction of thecartridge body 11, but also staggered in the radial direction of thecartridge body 11.

It should be noted that, the arrangement of the at least twosecond mating portions 1121 is matched with the arrangement of the at least twofirst mating portions 110, and only the first mating assembly and the second mating assembly can be matched together to realize the mating and separating of thehousing 110 and thebase 112, which is not described herein again.

More specifically, eachfirst mating portion 1103 is a slot disposed on one of thehousing 110 and thebase 112, and eachsecond mating portion 1121 is a buckle disposed on the other of thehousing 110 and thebase 112 and engaged with the slot.

Each slot comprises arotation stopping section 1103A and ananti-drop section 1103B, and therotation stopping section 1103A is connected with theanti-drop section 1103B in an intersecting manner. Each of the clips includes afirst clip portion 1121A and asecond clip portion 1121B, and thefirst clip portion 1121A intersects with thesecond clip portion 1121B. Thus, when each buckle is locked and screwed into each slot, thefirst locking portion 1121A is locked and restricted in the rotation-stoppingsection 1103A along the circumferential direction of thecartridge body 11, and thesecond locking portion 1121B is restricted in theanti-disengaging section 1103B along the axial direction of thecartridge body 11.

Further, a circumferential end of eachrotation stopping section 1103A is provided with a guide inclined plane 1103C for guiding eachfirst clamping portion 1121A to rotate in and out, so that the fastener is more labor-saving and convenient to rotate in and out of the clamping groove. The guiding slope 1103C may preferably be a flat smooth surface or a circular smooth surface, and the circular smooth surface may be a convex circular smooth surface or a concave circular smooth surface.

The following describes in detail the coupling structure and principle of thecasing 110 and the base 112 in the present application with thecartridge body 11 being a substantially hollow rectangular parallelepiped structure, and the present embodiment is only used as an example and does not limit the technical scope of the present application. For example, the shape of thecartridge body 11, the number of thefirst coupling portions 1103, and the number of thesecond coupling portions 1121 may be determined as necessary, and are not limited herein.

Specifically, each slot is generally in the shape of an inverted "L" that opens toward the bottom of the housing 110 (i.e., the end of thehousing 110 that mates with the base 112). Therotation stopping section 1103A extends lengthwise in the vertical direction, and theseparation preventing section 1103B extends lengthwise in the horizontal direction.

The second adapting assembly includes twosecond adapting portions 1121, each of the twosecond adapting portions 1121 is a buckle protruding from the surface of the base 112 facing thehousing 110, and the two buckles are respectively located at two ends of the diameter of the circumference where the buckle is located (specifically, in this embodiment, the two buckles are respectively located at two ends of one diagonal line of the base 112). Specifically, thefirst fastening portion 1121A of each fastening extends lengthwise along the axial direction of thecartridge body 11, thesecond fastening portion 1121B of each fastening extends perpendicularly from the end of thefirst fastening portion 1121A away from thebase 112, and the extending directions of the twosecond fastening portions 1121B are opposite. That is, each clip is an inverted "L" shape with an opening facing thebase 110, thefirst clip portion 1121A extends lengthwise along the vertical direction, and thesecond clip portion 1121B extends lengthwise along the transverse direction and is perpendicular to thefirst clip portion 1121A.

In the process of replacing theatomizing core 13, an external force acts on thebase 112 and rotates the base 112 in one circumferential direction (for example, the first circumferential direction), so that the buckle is withdrawn from the clamping groove, thebase 112 is separated from thehousing 110, and a user can take out theatomizing core 13 to be replaced from thehousing 110.

After theatomizing core 13 is replaced, thebase 112 is oriented so that the two buckles are toward the end of thehousing 110 having thefirst opening 1101, and the two buckles and the two clamping grooves are arranged in a staggered manner in the circumferential direction of thecartridge body 11; rotating the base 112 in another opposite circumferential direction (e.g., a second circumferential direction) so that the two fasteners move toward the two slots until thefirst fastening portion 1121A of each fastener falls into therotation stop portion 1103A to limit the rotation of the base 112 in the circumferential direction relative to thehousing 110; synchronously, thesecond blocking portion 1121B of each of the latches falls into the anti-falling-offsection 1103B to limit the movement of the base 112 in the axial direction relative to thehousing 110, so as to prevent the base 112 from falling off from thehousing 110.
