Detailed Description

The following describes in further detail the embodiments of the present utility model with reference to the drawings and examples. The following examples are illustrative of the utility model and are not intended to limit the scope of the utility model.

The present utility model provides an atomization core, please refer to fig. 2-3, which includes an atomization assembly 1, an atomization tube 2 and a fixing plug 3. The atomization assembly 1 comprises a heating body 11 and an oil guiding cotton 12, the heating body 11 is embedded in the oil guiding cotton 12 to heat tobacco tar in the oil guiding cotton 12, the oil guiding cotton 12 is coiled materials, the oil guiding cotton 12 is wrapped on the heating body 11, and then the redundant part is sheared off and plugged into the atomization tube 2, and the free edge of the oil guiding cotton 12 extends in a first direction. The first direction is generally the width direction of the web and is also the direction of extension of the central axis of the oil deflector 12. For convenience of description, the first direction is named up-down direction (as shown in the XY axis coordinates in fig. 2, the X axis direction represents the first direction). The free edge of the oil-guiding cotton 12 refers to an edge formed by cutting out the oil-guiding cotton 12 after wrapping the heating element 11.

The atomization tube 2 is provided with a containing cavity 21 for containing the oil guiding cotton 12 and an oil inlet 22 for communicating the containing cavity 21 with the outside, when the atomization core is arranged in an oil storage component (not shown), tobacco tar in the oil storage component (not shown) enters the oil guiding cotton 12 from the oil inlet 22, wherein the length of the oil inlet 22 along a first direction is not greater than the length of a free edge of the oil guiding cotton 12; alternatively, the width of the oil inlet 22 perpendicular to the first direction is not greater than the thickness of the oil deflector 12; of course, the length of the oil inlet 22 in the first direction may be not greater than the length of the free edge of the oil deflector 12, while the width perpendicular to the first direction is not greater than the thickness of the oil deflector 12. The fixed stopper 3 card is located the one end of atomizing pipe 2 for prevent that atomizing subassembly 1 and atomizing pipe 2 from taking place the displacement.

In the atomization core and the electronic cigarette, the atomization core is simple in structure, and the oil inlet 22 on the atomization tube 2 is not easy to turn over.

In this embodiment, the atomizing tube 2 includes a first tube section 23, a connecting portion 24 and a second tube section 25 sequentially connected along a first direction, two ends of each connecting portion 24 are respectively connected to the first tube section 23 and the second tube section 25, the plurality of connecting portions 24 are circumferentially distributed around a central axis of the atomizing tube 2, and an oil inlet 22 is formed between two adjacent connecting portions 24. Wherein, at least a part of the connecting part 24 covers the free edge of the oil guiding cotton 12, and generates a certain extrusion force to the free edge to prevent the free edge from flanging.

Specifically, the first tube section 23 and the second tube section 25 are used for gas circulation, when the atomization component starts to work and generates smoke, external air enters the electronic cigarette and flows through the second tube section 25, and then the smoke generated by atomization of the atomization component is carried out of the first tube section 23 through the connecting part 24 and flows to a suction nozzle (not shown) of the electronic cigarette for sucking by a user.

In the present embodiment, the connecting portion 24 includes a first connecting section 241 and a second connecting section 242 which are offset in the circumferential direction of the atomizing tube 2, and a third connecting section 243 which connects the first connecting section 241 and the second connecting section 242. Wherein at least one of the first connecting section 241, the second connecting section 242 and the third connecting section 243 is positioned at the free edge of the oil guiding cotton 12, covers the free edge, provides a pressing force, prevents the free edge from being turned out from the oil inlet 22,

it will be appreciated that the length of the oil inlet hole 22 in the first direction is not greater than the width of the oil deflector 12, in which case the wall of the atomizing tube 2 obstructs the end side of the free edge of the oil deflector 12 to avoid the free edge of the oil deflector 12 being exposed from the oil inlet hole 22 to cause burring. The width of the oil inlet 22 perpendicular to the first direction (i.e. the circumferential dimension of the oil inlet 22 along the atomizing tube 2) is not greater than the thickness of the oil guide cotton 12, and the situation that the free edge of the oil guide cotton 12 leaks from the oil inlet 33 to generate flanging can be avoided. Therefore, in order to ensure that the oil guide cotton 12 is not exposed from the oil inlet 22, the shape and size of the oil inlet 22 need to satisfy: the length of the oil inlet 22 in the first direction is not greater than the width of the oil guide cotton 12, or the width of the oil inlet 22 perpendicular to the first direction (i.e., the size of the oil inlet hole 22 in the circumferential direction of the atomizing tube 2) is not greater than the thickness of the oil guide cotton 12. It should be noted that, herein, the length of the oil inlet 22 along the first direction refers to the distance between two points of the axial section of the oil inlet 22, and is not the vertical distance between the highest point and the lowest point of the whole oil inlet 22; similarly, the width of the oil inlet 22 perpendicular to the first direction refers to the distance between two points of the oil inlet 22 on each cross section, rather than the arc length of the projection of the outermost circumferentially ends of the oil inlet 22 on the cross section.

In the case where the oil inlet 22 is rectangular in opening, the opening area of the oil inlet 22 is small, which is disadvantageous in that tobacco tar flows from the oil storage assembly (not shown) to the cotton wool 12, subject to the above-described restrictions.

The first connecting section 241 and the second connecting section 242 are arranged in a staggered manner in the circumferential direction of the atomizing pipe 2, in other words, the first connecting section 241 and the second connecting section 242 are located on different axial planes of the atomizing pipe 2 and are connected through the third connecting section 243, and the arrangement can furthest improve the open area of the oil inlet 22, so that the oil guiding performance is improved. Specifically, referring to fig. 2 or 3, the connecting portion 24 divides the area into an upper through hole located on the upper side of the third connecting section 243 and a lower through hole located on the lower side of the third connecting section 243, a gap is reserved between the third connecting sections 243 of two adjacent connecting portions 24, and in two adjacent connecting portions 24, the upper through hole of one connecting portion 24 and the lower through hole of the other connecting portion 24 are communicated through the gap and jointly form the oil inlet 22. With this design, the maximum area of the oil inlet 22 may be: the upper through hole and the lower through hole are rectangular holes, the dimension in the up-down direction is smaller than the width of the oil guiding cotton 22, the dimension of the gap in the left-right direction is slightly smaller than the thickness of the oil guiding cotton 22, in this case, the distance between the highest point and the lowest point of the whole oil inlet 22 can be larger than the width of the oil inlet 22, and the arc length of the farthest ends of the whole oil inlet 22 in the circumferential direction can exceed the limit of the thickness of the oil guiding cotton 22, so that the circulation of tobacco tar from the oil storage assembly to the oil guiding cotton 12 is facilitated.

In addition, the first connecting section 241 and the second connecting section 242 are arranged in a staggered manner in the circumferential direction of the atomizing pipe 2 and are connected through the third connecting section 243, so that the whole connecting portion 24 is in a bending state, and the structural strength of the connecting portion 24 can be effectively improved compared with that of a straight line section under the condition of the same volume from the mechanical angle.

In the structure shown in fig. 2 or 3, the third connecting section 243 is a straight section and extends along the circumferential direction of the atomizing tube 2, and in other embodiments, the third connecting section 243 may be a straight section and inclined to the circumferential direction of the atomizing tube 2, or be a curved section or other shape, which is not limited herein.

In this embodiment, the first connection section 241 and the second connection section 242 are straight sections and are arranged in parallel in the up-down direction, and in other embodiments, the first connection section 241 and the second connection section 242 may be straight sections and are arranged obliquely, or curved sections, etc., which are not limited only herein.

Specifically, in this embodiment, the connection portion 24 formed by sequentially connecting the first connection section 241, the third connection section 243 and the second connection section 242 is a central rotationally symmetrical structure, and at the same time, a plurality of connection portions 24 of the central rotationally symmetrical structure are uniformly distributed at intervals around the central axis of the atomizing tube 2 in the circumferential direction; a gap exists between the third connecting sections 243 between two adjacent connecting portions 24, and the width of the gap is smaller than the thickness of the oil deflector 12. The oil guide cotton 12 is plugged into the atomizing pipe 2 after being sheared, a shearing opening of the oil guide cotton 12 is arranged at the connecting part 24, and the connecting part 24 applies pressure to the shearing opening of the oil guide cotton 12, so that the shearing opening can be effectively prevented from flanging; the design of the center rotation symmetry maximizes the area of the oil inlet 22 on the premise of ensuring that the flange is not turned, and improves the oil guiding performance; the plurality of connecting portions 24 are arranged along the circumference of the atomizing pipe 2, so that the cut of the oil guiding cotton 12 can be effectively prevented from flanging no matter which direction is installed, and the consistency and stability of product output are greatly improved. Note that, the cutout of the oil deflector 12 refers to the free edge of the oil deflector 12.

The outer side of the oil deflector 12 rolled into a cylindrical shape abuts against the connecting portion 241, and the connecting portion 24 applies pressure to the cut of the oil deflector 12 to prevent the cut from being turned.

Specifically, the oil guide cotton 12 is rolled by a sheet-shaped cotton layer, and after the cotton layer is rolled into a cylinder shape, two opposite sides of the cotton layer are butted and bonded together, so that the manufacturing process is simple and convenient.

In this embodiment, referring to fig. 6, the fixing plug 3 is annular, and includes a plurality of protrusions 31, the protrusions 31 are circumferentially disposed on the outer side of the fixing plug 3 and abut against the inner side wall of the atomizing tube 2, a gap 32 is formed between two adjacent protrusions 31, and two conductive pins 112 respectively extend out of the atomizing tube 2 through the gap 32.

Specifically, the fixing plug 3 in this embodiment is installed in one end of the atomization tube 2 in an interference fit manner, so that the fixing plug 3 can be prevented from being exposed in the atomization tube 2, the process of assembling other parts in the electronic cigarette at the end of the atomization tube 2 is interfered, and when the fixing plug 3 is assembled, only the fixing plug 3 is required to be plugged into the atomization tube 2, and the assembly process is simple and quick. Of course, in other embodiments, the fixing plug 3 may be adhered inside or outside the atomizing tube 2, and the fixing plug 3 may mainly be abutted against the atomizing assembly 1.
