Embodiment 4

Tea cigarette cartridges are prepared respectively according to the smoke generating parts prepared in Embodiments 1-3. A structure of the tea cigarette cartridge prepared from bottom to top is: a sealing part 4, a smoke generating part 1, an isolation part 5, a purification part 21, an isolation part 5, a temperature control part 22, an isolation part 5, an air source part 23, an isolation part 5 and a filter 24. The entire tea cigarette cartridge is sleeved with a shaping part 3. For ease of understanding, the tea cigarette cartridges prepared according to the smoke generating parts prepared in Embodiments 1-3 are named a tea cigarette cartridge A, a tea cigarette cartridge B, and a tea cigarette cartridge C respectively.
In this embodiment, after the smoke generating part 1 generates smoke, the smoke is first purified by a tea stem purification part 21. Loose and porous tea stems can effectively absorb harmful substances in the smoke. At the same time, the tea stems in the purification part 21 can also enhance the aroma of the smoke, and tea polyphenols in the tea stems can also be refreshing. Therefore, the tea stem purification part 21 further has an effect of assisting in enhancing the aroma and refreshing, that is, assisting in strengthening the refreshing effect and the aroma enhancing effect of the smoke generating part 1. On the basis of ensuring a good filtration and purification effect on harmful substances in the smoke, the use of conventional filtration materials can be greatly avoided, which, on the one hand, can effectively reduce costs, and on the other hand, can also solve the problem of environmental pollution caused by difficult degradation of the conventional filtration materials.
In actual use, due to the complex structure of the tea cigarette cartridge, the structures are easy to loosen after being subjected to external force (such as insertion of heating plate insertion or smoking) or heating, and the structures easily influence each other, leading to a poor smoking effect. In this case, the isolation part 5 can effectively isolate the structures.
In order to effectively improve the stability of the structure of the tea cigarette cartridge, prevent various parts of the tea cigarette cartridge from loosening and falling off, and reduce the use of chemical components such as adhesives, the tea cigarette cartridge according to the embodiment of the present application further includes: a shaping part 3. The shaping part 3 is sleeved upon external surfaces of the smoke generating part 1 and the cigarette mouthpiece 2. The shaping part 3 is sleeved upon external surfaces of the smoke generating part 1 and the cigarette mouthpiece 2, so as to effectively maintain the structural stability of the tea cigarette cartridge, and after being affected by external vibration, can still maintain the structural stability of the tea cigarette cartridge to facilitate storage and transportation of the tea cigarette cartridge. At the same time, due to the shaping function of the shaping part 3, during the preparation of the tea cigarette cartridge, the method of pressing in one by one can effectively reduce the use of adhesive, which can prevent the release of harmful gases when the adhesive is heated and decomposed, and further improve the smoking taste of the tea cigarette cartridge, making the smoking safer.
The tea cigarette cartridge is further provided with a sealing part 4. The sealing part 4 is arranged under the smoke generating part 1, for preventing the content of the smoke generating part 1 from falling out. The arrangement of the sealing part 4 can effectively reduce damages to the cigarette structure during storage of the tobacco, and after the heating plate is inserted into the smoke generating part 1, the sealing part 4 can effectively prevent falling of the tobacco into the body of the electronic cigarette caused by looseness of the smoke generating part 1 due to heating and insertion of foreign matters and prevent pollution of the body of the electronic cigarette.

Embodiment 5

This embodiment is to measure smoking effects of the tea cigarette cartridges 1-3 prepared in Embodiment 4. In this embodiment, the tea cigarette cartridges 1-3 prepared in Embodiment 4 are evaluated for smoking tests, and evaluation results are shown in Table 1.

Tea cigarette cartridge b	Large amount of smoke	14	2950	Good	40	28 ppm
Tea cigarette cartridge c	Large amount of smoke	16	2980	Good	45	27 ppm

As shown in Table 1, the puff number of a single cigarette, the draw resistance, the smoke temperature, the taste and other technical parameters of the tea cigarette cartridge obtained in the technical solutions of the present application are all similar to those of existing electronic cigarette cartridges, therefore, the tea cigarette cartridge can act as an alternative to conventional cigarette cartridges from the perspective of smoking experience. Further, the tea polyphenols in the tea cigarette cartridge obtained have a good takeout effect, and the tea polyphenols have a good refreshing effect. Therefore, the tea cigarette cartridge can also act as an alternative to conventional cigarette cartridges from the perspective of refreshing requirements.
The present application further provides an electronic cigarette, including a heating unit, an energy storage unit, a control unit and the cigarette structure as described above. The control unit controls the heating unit for heating, and the energy storage unit provides energy for a heating process of the heating unit.
