Preferably, the heater 3 is a ceramic heater to improve heating efficiency. Alternatively, the heater 3 may have a length of about one-fourth to one-half of the length of the regular cigarette 100, i.e., about 10mm to 30mm, and the heater 3 may have a length of 13mm in this embodiment. Compared with other existing heaters 3, the heater 3 of the invention has shorter size and smaller volume, and has the characteristics of high heating efficiency, small heat dissipation and high energy utilization rate under the condition of supplying energy by the battery 24 with the same power, thereby being capable of heating the cigarettes 100 more quickly and better.
Alternatively, the heater 3 may be driven by the motor 21 to move along the cigarette 100 from bottom to top or from top to bottom for heating. In this embodiment, the heater 3 is driven by the motor 21 to move along the cigarette 100 from the bottom to the top, i.e., from the bottom of the cigarette 100 to the filter end of the cigarette 100. Specifically, as shown in fig. 5 and 6, wherein fig. 5 shows the heater 3 in the home position; figure 6 shows the heater 3 moved to the bottom of the cigarette 100, i.e. the initial heating position, when the cigarette 100 is inserted into the housing 1, the switch button 6 is actuated; as the user draws on the cigarette 100, the heater 3 moves from the base of the cigarette 100 progressively towards the filter end until it stops moving to a point adjacent the underside of the filter of the cigarette 100, i.e. back to the original position shown in figure 5. This moving, continuous, uninterrupted heating allows the interior of the cigarette 100 to be fully baked.
In order to avoid preheating the heater 3 for a plurality of times during heating, the heater 3 of the present invention has two temperature ranges, one is a preheating temperature range, and the other is a baking temperature range. Specifically, the preheating temperature range is 150-240 ℃, and the baking temperature range is 240-350 ℃. In use, the cigarette 100 is inserted into the housing 1, the switch button 6 is pressed, the electronic cigarette roaster is started, the heater 3 moves to the position in fig. 6 and the heater 3 heats to a roasting temperature range to roast the cigarette 100 for the user to smoke; when the preset time (which can be set to several seconds) is exceeded and the user has not smoked the cigarette 100, the heater 3 is warmed back to the preheating temperature range to prepare for the next baking, thereby reducing the preheating waiting time and the energy consumption.
Further, to ensure that the heater 3 is baked or preheated within a preset temperature range, the electronic cigarette roaster further comprises a temperature sensor 9.

A sensor 101 is mounted on the circuit board 10 for detecting whether the cigarette 100 is inserted into the housing 1. When the cigarette baking machine is used, the switch button 6 is pressed to start the electronic cigarette baking machine, the circuit board 10 controls the motor 21 and the heater 3 to start working after the sensor 101 senses that the cigarette 100 is inserted into the shell 1, and otherwise, the motor 21 and the heater 3 are not started. Preferably, the sensor 101 is an infrared sensor.
To ensure that the heater 3 can move with the user's smoking, the electronic vaper further includes an airflow sensor 102. The airflow sensor 102 is in communication with the through-hole for detecting the air pressure within the through-hole. And the airflow sensor 102 is connected to the circuit board 10 to transmit the information of the air pressure change in the through hole to the circuit board 10. Alternatively, the gas flow sensor 102 is mounted on the second electrode plate 5, and communicates with the through hole through a gas transmission passage. When a user sucks the cigarette, the lower end of the cigarette 100 in the through hole generates airflow change, so that the air pressure in the through hole is in a negative pressure state, at the moment, the airflow sensor 102 transmits the information of the air pressure change to the circuit board 10, and the circuit board 10 controls the heater 3 to be heated to the baking temperature on one hand; on the other hand, the control motor 21 is started to drive the heater 3 to move upwards; when the user stops the suction, the air flow in the through hole tends to be stable, the circuit board 10 controls the heater 3 to return to the preset temperature range, and controls the motor 21 to stop rotating, so that the heater 3 stops moving.
Optionally, in order to prevent the heater 3 from moving and the cigarette 100 from shaking, the electronic flue-cured tobacco further comprises a first supporting part 104, the first supporting part 104 is provided with a through hole, one end of the cigarette 100, which is far away from the filter tip, is arranged in the through hole, and one end of the heater 3 can be inserted into the through hole. Specifically, the first support 104 is connected to the second electrode plate 5 so that the lower end thereof can be placed in the through hole when the heater 3 is in the initial heating position and the end of the cigarette 100 away from the filter is placed in the through hole when the heater 3 is moved upward.
In order to further clamp and fix the cigarette 100, the electronic flue-cured tobacco further comprises a second supporting part 105, the second supporting part 105 is tubular, is installed in the housing 1 and is located at the cigarette insertion opening 121, the cigarette 100 passes through the second supporting part 105, and the filter end of the cigarette 100 is abutted against the inner wall of the second supporting part 105.

Specifically, one end of the heat insulation sleeve 106 is sleeved on the outer periphery of the first supporting portion 104 and abuts against the step on the outer periphery of the first supporting portion 104, and the other end is sleeved on the outer periphery of the second supporting portion 105, that is, the heater 3 always moves inside the heat insulation sleeve 106, and can always insulate heat. And the heat insulation sleeve 106 is axially sleeved on the periphery of the cigarette 100, so that the flow converging and guiding functions on the smoke generated by the cigarette 100 can be realized, and the sufficient smoke can be sucked out when a user sucks the smoke. Further, a strip-shaped avoiding opening is axially formed in one side, facing the screw rod 22, of the heat insulation sleeve 106, and the connecting piece 23 drives the heater 3 to move within the range of the strip-shaped avoiding opening. Compared with the heater 3 in the prior art, the heater 3 provided by the invention has smaller volume and smaller heating source, so that the requirement on the heat insulation sleeve 106 is not high, the common heat insulation material and heat insulation mode are only needed, and the process and production cost is reduced.

3. if the airflow sensor 102 detects that the user does not perform the pumping action within the preset time, the circuit board 10 controls the temperature of the heater 3 to be reduced to the preheating temperature range (150 ℃ -240 ℃), and the circuit board 10 controls the heater 3 to stop moving;
4. if the airflow sensor 102 detects that the user generates a suction action, the circuit board 10 controls the driving assembly 2 to drive the heater 3 to move towards the filter end of the cigarette 100 at a certain speed (which can be set as required), and the circuit board 10 controls the temperature of the heater 3 to rapidly rise to a baking temperature range (240 ℃ -350 ℃), so that the cigarette 100 is heated in a moving manner.
5. The heater 3 moves to the filter end of the cigarette 100 and the heater 3 stops moving and heating.
It can be seen that in the electronic tobacco flue-curing device, the heater 3 moves and heats along with the smoking action of the user, so that the manual burning smoking process is simulated, and good user experience is brought to the user.
