The filtering structure 105 is disposed in the body 100, but is not limited thereto. The atomizer 200 is disposed within the atomization chamber 103.

Specifically, the air inlet chamber 102, the atomization chamber 103 and the smoke outlet chamber 104 are arranged and communicated in sequence. The filter structure 105 is disposed within the smoke exit chamber 104. The body 100 is provided with an air inlet 106 communicating with the air inlet chamber 102, an air outlet 107 communicating with the air inlet chamber 102 and the atomization chamber 103, respectively, a smoke suction port 108 communicating with the smoke outlet chamber 104, and a smoke inlet 109 communicating with the atomization chamber 103 and the smoke outlet chamber 104, respectively. A smoke guide 1051 extends from the smoke suction port 108 in the filter structure 105. The outer wall of the smoke guide 1051 and the inner side wall of the filter structure 105 form an annular chamber 1001. The side wall of the filter structure 105 is provided with a first smoke outlet 1053. The first smoke guide 1053 is respectively communicated with the smoke inlet 109 and the annular cavity 1001. The smoke guiding part 1051 is provided with a smoke guiding hole 1052 and a second smoke guiding port 1054. The smoke guide hole 1052 is communicated with the smoking port 108. The second smoke guide 1054 is disposed at an end of the smoke guide 1051 facing away from the smoking port 108, but is not limited thereto. The second smoke guide port 1054 is respectively communicated with the annular cavity 1001 and the smoke guide hole 1052. The first smoke guide 1053 is located upward of the lower end of the smoke guide 1051.

The first smoke outlet 503 is provided in the upper direction of the lower end of the second smoke outlet 504.

In this embodiment, the first housing 510 is further provided with a guide portion 511 formed by extending from an outer peripheral wall thereof to one side. The first smoke guide 503 passes through the guide 511. It is understood that in other embodiments, the guide portion 511 may be omitted.

It can be understood that by extending the length of the smoke guiding part 501 and the length of the annular cavity 502 along the axial direction, the path of the smoke making spiral motion is longer, so as to improve the separation and filtration effect of the smoke.

Referring to fig. 9, the present invention further provides a cigarette holder 600. The mouthpiece 600 comprises a sleeve 601 and a filter structure 500. The jacket 601 is provided with a first accommodating cavity 6011, a second accommodating cavity 6013 and a smoke outlet 6015 which are communicated in sequence. The first accommodating chamber 6011 is used for accommodating the electronic cigarette or the cartridge. The second receiving cavity 6013 is configured to mount the filter structure 500, and the first smoke guide opening 503 is communicated with the first receiving cavity 6011. The smoke outlet 6015 communicates with the smoke guide hole 505.

The smoke generated by the electronic cigarette or cartridge enters the annular cavity 502 through the first smoke guide opening 503 in the guide portion 511. The smoke forms a cyclone in the annular cavity 502, liquid or solid particles in the smoke spirally move downwards along the annular cavity 502 to the second smoke guide opening 504 under the action of centrifugal force and collide with the inner wall of the filter structure 500, so that the kinetic energy difference between the gas and the liquid/solid particles is obvious, the oil and the gas are separated, meanwhile, the liquid or solid particles can be adhered to the inner wall of the filter structure 500 and gather towards the bottom wall of the filter structure 500 under the action of gravity, and the smoke is filtered. The filtered smoke is discharged from the smoke outlet 6015.

In this embodiment, the casing 601 is made of soft rubber, but is not limited thereto. It is understood that the sleeve 601 may be made of other soft materials so as to be sleeved outside the electronic cigarette.

In the filter structure, smoke generated after heating and atomizing tobacco tar enters the annular cavity through one of the first smoke guide opening and the smoke guide hole, the smoke moves along a spiral path in the annular cavity to form a cyclone, and under the action of centrifugal force, impurities such as liquid or solid particles collide with the inner wall of the filter structure to separate the impurities from gas. Liquid or solid-state granule rely on gravity to the diapire gathering of filtration, realize the filtration of smog, and the smog after the filtration is discharged from another in first smoke guide mouth and the smoke guide hole, and filtration's air resistance is little, improve and inhale the taste. And the filtering structure can be independently arranged inside or outside the cigarette cartridge, the cigarette holder or the electronic cigarette, and has simple structure and convenient installation.

In addition, other modifications within the spirit of the invention may occur to those skilled in the art, and such modifications are, of course, included within the scope of the invention as claimed.
