     Further, in this embodiment, the plurality of first liquid absorbing grooves  122  are disposed on an inner sidewall of the air outlet tube  12  and disposed at intervals in a circumferential direction of the air outlet channel  121 . When vapor reaches an air outlet through the air outlet channel  121 , airflow around the air outlet channel  121  is condensed when encountering the inner sidewall of the air outlet tube  12  to form condensed liquid, and in this case, the first liquid absorbing groove  122  may absorb the condensed liquid into the groove through capillary force.

     In this embodiment, the liquid absorbing structure  101  includes a plurality of fins  104 . The fins  104  are longitudinally disposed in parallel or not in parallel and at intervals, and a liquid storage groove  105  is formed between every two adjacently disposed fins  104 .

The first liquid absorbing structure and the second liquid absorbing structure absorb condensed liquid formed on the air outlet channel  121  through capillary force. The second liquid absorbing structure is located between the vaporization component  30  and the first liquid absorbing structure, and the capillary force of the second liquid absorbing structure is greater than that of the first liquid absorbing structure. The second liquid absorbing structure is provided with a liquid storage groove  105  that absorbs and stores the condensed liquid through capillary force.

     In other embodiments, the second liquid absorbing structure may be formed on an integrally formed separate element. For example, the air outlet tube  12  and the vaporization component  30  are disposed adjacent to each other in a longitudinal direction, the second liquid absorbing structure and the air outlet tube  12  may be an integral structure, and the liquid storage groove  105  is opened on an inner wall surface of the air outlet tube  12 . In this embodiment, the second liquid absorbing structure and the air outlet channel  12  are split structures. The second liquid absorbing structure includes a cylinder-shaped body disposed right above the vaporization component  30 , and the air inlet channel  131 , the vaporization cavity  311 , the inner cavity of the second liquid absorbing structure, and the air outlet tube  12  form a complete airflow channel. 
     As shown in  FIG. 13  and  FIG. 14 , the air outlet tube  12  includes a first end  1211  close to the vaporization component  30  and a second end  1212  away from the vaporization component  30 . The liquid absorbing groove  122  is longitudinally disposed in an extending manner from the first end  1211  of the air outlet tube  12  to the second end  1212  of the air outlet tube  12 , there are a plurality of liquid absorbing grooves  122  uniformly distributed along a peripheral wall of the air outlet channel  121 , and the liquid absorbing grooves are parallel to a central axis of the air outlet channel  121 .

     As shown in  FIG. 11 , the vaporization component  30  includes a cylinder-shaped vaporization core  321 , a liquid guiding cotton  323  surrounding the vaporization core  321 , and a heating element  322  wound on the vaporization core  321 . A conductive connection portion of the heating element  322  runs through the base  20  to be connected to an electrode  90 . In some embodiments, the heating element  322  may be a heating wire. In a use process, the liquid guiding cotton  323  absorbs e-liquid in the liquid storage cavity  111 , and the heating element  322  is powered on and generates heat, to vaporize the e-liquid in the vaporization core  321 .

     When vapor reaches an air outlet through the air outlet channel  121 , airflow around the air outlet channel  121  is condensed when encountering the inner sidewall of the air outlet tube  12  to form e-liquid condensed liquid, and in this case, the liquid absorbing groove  122  absorbs the condensed liquid into the groove through capillary force. Since the capillary force of the liquid storage groove  105  is greater than the capillary force of the liquid absorbing groove  122 , the condensed liquid in the liquid absorbing groove  122  reaches the second liquid absorbing structure under action of the capillary force of the liquid storage groove  105  to be absorbed and stored.

The reflux structure is a reflux groove, a liquid outlet, or a stage structure. 
     As shown in  FIG. 15 , in some embodiments, the liquid storage groove  105  is a transverse liquid storage groove. Specifically, the inner wall of the second liquid absorbing structure is provided with a plurality of first fins  104 . The first fins  104  are longitudinally disposed in parallel and at intervals, and a transverse liquid storage groove is formed between every two adjacently disposed first fins  104 . A width of the liquid storage groove  105  is small enough to generate capillary force to the condensed liquid, so that liquid drips carried in vapor generated in an inhaling process may stay in the liquid storage groove  105  due to the structure of the first fins  104 , thereby forming a liquid film in the liquid storage groove  105  and further being stored in the liquid storage groove  105 , and preventing leaked liquid from being inhaled.
