- the user starts the operation by the control controller 6 of the switch 7, and the temperature adjustment button can also be set at the switch 7 to facilitate the user to manually set the first predetermined temperature of the heating element 13, in this embodiment
- a predetermined temperature is 200 ° C, and the first predetermined temperature in other embodiments may be 80 ° C - 300 ° C.
- step S22 the airflow sensor 5 continues to detect the airflow signal, proceeds to step S23; the airflow sensor 5 does not detect the airflow signal again, proceeds to step S24; [0085] S23, the controller 6 controls the heating element 13 to be heated to a second predetermined temperature, and the temperature sensor 3 measures the temperature of the first cavity 11 and transmits a temperature signal to the controller 6, when the detected temperature is lower than the first Two predetermined temperature ⁇ , the controller 6 controls the heating element 13 to continue heating, and when the temperature is higher than the second temperature ⁇ , the controller 6 controls the heating element 13 to stop heating;
- the controller 6 controls the heating element 13 to continue heating, so that the temperature in the first cavity 11 is maintained at a higher level.
- the predetermined temperature is further to enhance the mouthfeel of the user's smoking sputum.
- the second predetermined temperature is 20 ° C to 30 ° C higher than the first predetermined temperature. In the present embodiment, the second predetermined temperature is 230 ° C.
- the temperature sensor 3 measures the temperature of the first cavity 11 and transmits a temperature signal to the controller 6. When the detected temperature is lower than the first predetermined temperature, the controller 6 The heating element 13 is controlled to continue heating, and when the temperature is higher than the first predetermined temperature, the controller 6 controls the heating element 13 to stop heating.
- the controller 6 will control the heating element 13 to heat to maintain the temperature in the first cavity 11. It is the first predetermined temperature.
- the operation of the heating element 13 can be controlled according to the smoking action of the user, and the temperature in the first cavity 11 can be adjusted to improve the smoking taste and the smoking taste of the user.
- the heating temperature of the heating element 13 is lowered to save energy.
- the controller 6 has a storage function for storing a preset set temperature, and the controller 6 further has a judging process, and when the detected temperature is lower than a predetermined temperature, the controller 6 controls the heating element. 13 continues heating, and when the temperature is higher than the predetermined temperature, the controller 6 controls the heating element 13 to stop heating.
- the controller 6 can also have a counting function. When the heating element 13 reaches the predetermined temperature for the first time, the controller 6 controls the heating element 13 to stop heating when the user smokes for more than a predetermined length.
- a predetermined day adjustment button can also be set. The user can set the smoking room by the button to protect the life of the evaporator, and also protect the user from smoking too long.
- the tobacco evaporator of the present invention disperses the heat generated by the heat generating component by providing a mesh filter layer structure, so that the substance to be evaporated which is placed on the mesh filter layer structure is uniformly heated, so that the heat does not appear. Bake out of the paste; also by providing a heat shield on the first cavity, insulation, and in the second The heat insulating structure, the heat insulating layer and the like are disposed outside the cavity, and the heat generating element is heated to slow the heat dissipation of the tobacco evaporator, thereby shortening the preheating time of the heating wire and conserving the battery power.
- the technical problem that the tobacco evaporator in the prior art can not ensure the short preheating time and the low energy consumption, and the softness of the baking outlet and the uniform baking is effectively solved.
