[0038] The electronic cigarette 100 provided in the embodiment of the present application is described in detail below through specific embodiments in conjunction with all the drawings of the specification.

[0039] Please refer to Figure 1 , Figure 2 and Figure 3 In one embodiment of the utility model, an electronic cigarette 100 is disclosed, including a main body 10 and a flexible sealing ring 20. The main body 10 is provided with a heating chamber 102, and the heating chamber 102 runs through one end of the main body 10; the flexible sealing ring 20 includes a main body 22, a first annular protrusion 24 and an elastic sealing portion 26. The main body 22 is installed on the main body 10, and the main body 22 is located at the cavity opening of the heating chamber 102. The main body 22 is provided with a plug-in groove 202, and the plug-in groove 202 is connected to the heating chamber 102. The first annular protrusion 24 is connected to the groove wall of the plug-in groove 202, and the elastic sealing portion 26 is connected to the first annular protrusion 24. The elastic sealing portion 26 extends inward from the first annular protrusion 24, and there is a gap between the outer side of the elastic sealing portion 26 and the groove wall of the plug-in groove 202. The inner side of the elastic sealing portion 26 is used to abut against the outer surface of the cigarette.

[0040] The cigarette is interference fit with the elastic sealing part 26. With the above structure, when inserting the cigarette into the heating chamber 102, the outer surface of the cigarette abuts against the inner side of the elastic sealing part 26, so that the elastic sealing part 26 undergoes elastic deformation; since there is a gap between the outer side of the elastic sealing part 26 and the groove wall of the insertion groove 202, the elastic sealing part 26 tilts toward the body 22 after deformation, so that the elastic sealing part 26 can clamp the cigarette and seal the gap between the cigarette and the cavity wall of the heating chamber 102, so that when smoking the cigarette, the outside air cannot enter the heating chamber 102 through the gap between the cigarette and the cavity wall of the heating chamber 102, and finally the smoke in the heating chamber 102 will not be excessively diluted, thereby increasing the concentration of the smoke.

[0041] Specifically, in this embodiment, the elastic sealing portion 26 extends from the first annular protrusion 24 to the heating chamber 102; the flexible sealing ring 20 is made of silicone material, and the body 22, the first annular protrusion 24 and the elastic sealing portion 26 are all in annular shape.

The side of the main body 22 facing away from the heating cavity 102 is provided with a plurality of inner grooves 2202, and all the inner grooves 2202 are evenly distributed around the central axis of the main body 22.

[0044] Through the above structure, the body 22 is embedded in the installation cavity 104, and the cavity wall of the installation cavity 104 plays a clamping role on the body 22, so that the body 22 is fixed relative to the main body 10, and the main body 10 and the flexible sealing ring 20 can be connected to each other without additional parts, which simplifies the structure of the electronic cigarette 100. In addition, the body 22 seals the installation cavity 104, so that the gas outside the heating cavity 102 cannot flow into the heating cavity 102 through the installation cavity 104, further improving the sealing performance at the cavity opening of the heating cavity 102 when a cigarette is placed in the heating cavity 102.

[0045] In addition, when the main body 22 is installed in the installation cavity 104, the side of the main body 22 facing away from the heating cavity 102 abuts against the cavity wall of the installation cavity 104, and then the main body 22 is squeezed and deformed, and the volume of the inner groove 2202 becomes smaller. The inner groove 2202 accommodates the deformation of the main body 22, making it easier for the main body 22 to be installed in the installation cavity 104.

[0048] In other embodiments, the body 22 may be installed on the main body 10 in other ways, such as snap-fitting or pasting; the cross-section of the inner groove 2202 may also be other shapes, such as a rectangle.

[0049] In some embodiments, the main body 10 includes a partition wall 11, which is located between the heating chamber 102 and the installation chamber 104. The flexible sealing ring 20 also includes a second annular protrusion 28, which is connected to the inner surface of the main body 22.

[0059] Through the above structure, when the cigarette located in the heating chamber 102 is heated, tar and cigarette residue may be produced in the cigarette, the tar is absorbed by the oil absorption component 30, and the cigarette residue is blocked by the oil absorption component 30 and adheres to the surface of the oil absorption component 30; therefore, when the user inhales the electronic cigarette 100, the tar and cigarette residue will not leak out through the air inlet 1502.

[0060] Specifically, in this embodiment, the oil absorbent 30 is oil absorbent cotton, the oil absorbent 30 is cylindrical, and the shape of the filter cavity 1602 is adapted to the oil absorbent 30. In other embodiments, the oil absorbent 30 can also be made of other materials, such as sponge; the oil absorbent 30 can also be other structures, such as a cuboid.

[0066] Through the above structure, the external gas can be connected to the heating chamber 102 through multiple air guide holes 1902 at the same time, so that the external gas flowing into the heating chamber 102 is more uniform, and smoke is generated in the heating chamber 102 after the cigarette is heated, and the external gas can be more fully in contact with the smoke in the heating chamber 102, so that the smoke and the external gas can be more fully mixed. In addition, one end of the cigarette extending into the heating chamber 102 can be partially embedded in the conical blind groove 1904, so that there is a gap between the end of the cigarette and the cavity wall of the conical blind groove 1904, so that the end of the cigarette will not block the air guide hole 1902, and the external gas can flow into the heating chamber 102 more uniformly through each air guide hole 1902.

[0067] Specifically, in this embodiment, the conical blind groove 1904 is coaxially arranged with the heating chamber 102, and the air guide hole 1902 is a circular through hole, wherein the central axis of one of the air guide holes 1902 is colinear with the central axis of the conical blind groove 1904, and the other air guide holes 1902 are arranged around the central axis of the conical blind groove 1904, and the central axes of all the air guide holes 1902 are parallel to each other.

[0070] Through the above structure, the air inlet 1502 and the vent 1604 are staggered, so that when the user does not smoke the cigarette, even if the external gas flows into the air inlet 1502, it is difficult to continue to flow into the vent 1604, thereby reducing the possibility of the electronic cigarette 100 being accidentally started when not being smoked.

[0071] Specifically, in this embodiment, the vent hole 1604 is a circular through hole, the vent hole 1604 is coaxially arranged with the filter cavity 1602, and the aperture of the vent hole 1604 is smaller than the diameter of the filter cavity 1602. In other embodiments, the vent hole 1604 can also be other structures, such as a rectangular through hole.

[0072] Please refer to Figure 3 In some embodiments, the elastic sealing portion 26, the first annular protrusion 24 and the plug-in slot 202 are coaxially arranged, and the inner diameters of the elastic sealing portion 26, the first annular protrusion 24 and the plug-in slot 202 increase in sequence.

[0073] Through the above structure, the diameter of the cigarette is larger than the inner diameter of the elastic sealing part 26 and smaller than the inner diameter of the first plug-in slot 202. When the cigarette is inserted into the plug-in slot 202, the cigarette can abut against the inner surface of the elastic sealing part 26, so that the elastic sealing part 26 undergoes elastic deformation, and the elastic sealing part 26 will not contact the slot wall of the plug-in slot 202, so that the elastic sealing part 26 can have a better sealing effect on the heating chamber 102.

[0074] In some embodiments, the first annular protrusion 24 includes a guide bevel 242, which is located on the side of the first annular protrusion 24 facing the heating chamber 102; in the direction in which the flexible sealing ring 20 extends into the heating chamber 102, the area enclosed by the guide bevel 242 gradually decreases, and the first annular protrusion 24 and the elastic sealing portion 26 are arranged in sequence.

[0075] Through the above structure, when the cigarette is inserted into the heating chamber 102, one end of the cigarette extending into the heating chamber 102 abuts against the guide slope 242, causing the guide slope 242 to elastically deform, and then the end of the cigarette abuts against the elastic sealing part 26, causing the elastic sealing part 26 to elastically deform; the guide slope 242 guides the end of the cigarette, making it easier to insert the cigarette into the heating chamber 102.

[0076] Specifically, in the present embodiment, the guiding inclined surface 242 is a curved surface, and the guiding inclined surface 242 forms a structure similar to a truncated cone; in other embodiments, the guiding inclined surface 242 may also be a plane.
