Among them, the atomization component may include an oil cup 121, an oil guide cotton 122, a mist guide tube 123, a heating element 124, etc. The mist guide tube 123 connects the air inlet 113 and the mist outlet 114, and the oil cup 121 is used to contain e-liquid. Part of the oil-conducting cotton 122 is in contact with the e-liquid, part is located in the mist guide tube 123, and is in contact with the heating element 124, and the heating element 124 is in contact with the power-connecting electrode 130. It should be noted that the e-liquid can flow through the oil guide cotton 122 to the part of the oil guide cotton 122 located in the mist guide tube 123 . When the reusable electronic cigarette is in the assembled state and starts to work, the battery 225 of the power supply component supplies power to the circuit board 221, and the circuit board 221 supplies power to the power electrode 130 through the power supply electrode 230, so that the heating element 124 is in contact with the power electrode 130. It generates heat, so that the e-liquid in the oil-conducting cotton 122 in contact with the heating element 124 is heated and evaporates into smoke, and the smoke is then emitted through the mist outlet 114 for the user to smoke. It is worth noting that the atomization assembly may also include a cigarette holder oil-absorbing cotton 125, a heating element fixing seat 126, etc. The cigarette holder oil-absorbing cotton 125 is located above the mist guide tube 123 and can be used to absorb the insufficient atomization emitted from the mist guide tube 123. of smoke oil particles, and the fixing base of the heating element 124 can be installed on the second housing for fixing the heating element 124 .
