Abstract

An electronic cigarette is provided, which includes a connection structure between a battery assembly and an atomizer assembly. In the connection structure, a first connection member and a second connection member are connected. The second connection member defines a joint slot for receiving the first connection member. An elastic member includes a bulge radially protruding inward from an inner wall of the joint slot, or radially protruding outward from the first connection member. A buckle slot matched with the bulge is defined in an inner side of the second connection member or is defined in the outer side of the first connection member. The first connection member is inserted in the joint slot and is rotated to press and deform the bulge. When the bulge is rotated to enter the buckle slot, the bulge impacts an inner wall of the buckle slot to generate an indicating sound.

Claims

1. An electronic cigarette, comprising an atomizer assembly and a battery assembly;

a connection structure for connecting the atomizer assembly with the battery assembly mounted at a joint between the battery assembly and the atomizer assembly;

the connection structure including a first connection member and a second connection member, and the first connection member connected with the second connection member;

wherein the second connection member defines a joint slot for receiving the first connection member;

an elastic member is mounted on the first connection member or the second connection member, and the elastic member includes a bulge that radially protrudes inward from an inner wall of the joint slot or radially protrudes outward from the first connection member;

correspondingly, a buckle slot matched with the bulge is defined in an outer side of the first connection member or is defined in the inner wall of the joint slot of the second connection member;

wherein the second connection member includes a jamming base, and the joint slot is defined in the jamming base;

at least one guiding slot configured to receive the bulge is defined in one side wall of the jamming base;

a first step is formed on an inner wall of the jamming base, and the first step is positioned adjacent to the guiding slot and protrudes from the inner wall of the jamming base;

the first step and the inner wall of the jamming base cooperatively form the buckle slot the first step includes a first step plane positioned adjacent to the guiding slot;

when the atomizer assembly is connected with the battery assembly, the first connection member is inserted into the joint slot and is rotated to press and deform the bulge; and

when the bulge is rotated to enter the buckle slot, the bulge slides along the first step plane and crosses the first step plane to impact an inner wall of the buckle slot to generate an indicating sound and is then buckled in the buckle slot.

2. The electronic cigarette according to claim 1, wherein, the jamming base has an opening end, and a diameter of the opening end contracts inward to form a limiting step;

the limiting step is configured to limit an axial location of the bulge.

3. The electronic cigarette according to claim 1, wherein, the jamming base defines at least two guiding slots, and a second step is formed between two adjacent ones of the guiding slots;

the second step includes a second step plane inclining to the same inclining direction as the first step plane; and

the first step, the second step, and a portion of the inner wall of the jamming base between the first step and the second step cooperatively form the buckle slot.

4. The electronic cigarette according to claim 3, wherein, a side surface of the second step which is opposite to the second step plane is coplanar with a side surface of the guiding slot which is away from the first step.

5. The electronic cigarette according to claim 1, wherein, the buckle slot is a concave spot.

6. The electronic cigarette according to claim 1, wherein, the elastic member mounted on the first connection member is an elastic piece with an annular structure, and the bulge is a ridge radially protruding outward from the elastic piece;

and when the first connection member is inserted into the joint slot, the ridge is pressed to deform, and then impacts the inner wall of the buckle slot defined in the joint slot to generate the indicating sound.

7. The electronic cigarette according to claim 6, wherein, the first connection member includes a first outer electrode configured to enable the electrical connection between the atomizer assembly and the battery assembly;

a first through hole configured to enable the ridge to stretch out is defined in one side wall of the first outer electrode;

the elastic member is mounted inside the first outer electrode; and

the ridge runs through the first through hole and protrudes from the outer side of the first outer electrode.

8. The electronic cigarette according to claim 7, wherein, a first inner electrode configured to enable the electrical connection between the atomizer assembly and the battery assembly is inserted in the first outer electrode;

a first insulating member is disposed between the first inner electrode and the elastic member; and

a diameter of an outer side wall of the first insulating member contracts to form an annular groove for mounting the elastic member.

9. The electronic cigarette according to claim 1, wherein, the elastic member is an elastic block fixed on and protruding from the outer side wall of the first connection member or the inner side wall of the second connection member.

10. The electronic cigarette according to claim 9, wherein, the elastic block includes a fixed sleeve and the bulge;

and the bulge is partially sheathed in the fixed sleeve and is movably connected to the fixed sleeve.

11. The electronic cigarette according to claim 10, wherein, the bulge and the fixed sleeve cooperatively form a receiving cavity;

a spring is inserted in the receiving cavity;

one end of the spring abuts the bulge, and the other end of the spring abuts a bottom of the receiving cavity; and

the spring is configured to apply an elastic force to the bulge along a radial direction of the electronic cigarette.

12. The electronic cigarette according to claim 6, wherein, a buckle convex block is formed on the outer side wall of the first connection member;

the buckle convex block is positioned at a side of the elastic member which is away from the second connection member or a side of the buckle slot which is away from the second connection member; and

the buckle convex block is inserted in the second connection member and is then limited within the joint slot after being rotated.

13. The electronic cigarette according to claim 9, wherein a buckle convex block is formed on the outer side wall of the first connection member;

the buckle convex block is positioned at a side of the elastic member which is away from the second connection member or a side of the buckle slot which is away from the second connection member; and

the buckle convex block is inserted in the second connection member and is then limited within the joint slot after being rotated.

14. The electronic cigarette according to claim 5, wherein, a buckle ring is formed on the outer side wall of the first connection member;

the buckle ring is positioned at a side of the elastic member which is away from the second connection member or a side of the buckle slot which is away from the second connection member;
