When the fixing base 202 moves down to touch the travel switch 205 located at the bottom dead center, the driving motor 400 stops rotating, and at this time, the heating chamber 100 is opened.
2) The cigarette is placed in the heating chamber 100 of the base 101 and a heating command is given to the smoking article.
3) The driving motor 400 rotates forward, and the following actions occur in the process of upward movement of the screw rod 404: the fixed seat 202 upwards releases the pull rod 305, the turntable 303 rotates under the action of the torsion spring, so that the revolving door 300 is closed, and the cigarettes are clamped by the revolving door 300 because the cigarettes are inserted into the heating cavity; the screw rod 404 continues to move upwards, and the heating body 200 is inserted into the cigarette in a rotating way; until the elastic electrode 203 contacts the conductive plate 204, the circuit of the heating body 200 is switched on; meanwhile, when the fixed seat 202 moves to the travel switch 205 touching the top dead center, the driving motor 400 stops rotating.
4) The heating body 200 starts the heating process and the cigarettes are baked.
5) After the smoking of the cigarettes is completed, a cigarette changing instruction is given to the smoking set, the driving motor 400 is reversed, and the following actions occur in the downward movement process of the screw rod 404: a travel switch 205 for the fixed seat 202 to leave the top dead center; the elastic electrode 203 is separated from the conductive plate 204, and the circuit of the heating body 200 is disconnected; the heating element 200 is separated from the cigarette while rotating; the fixing base 202 pulls the pull rod 305 downwards, the pull rod 305 enables the turntable 303 to rotate through the connected lever 306, and the revolving door 300 loosens cigarettes; when the fixed seat 202 moves to the travel switch 205 touching the bottom dead center, the driving motor stops rotating.
6) The cigarette is removed from the heating chamber 100 of the base 101 and a turnstile closing command is given to the smoking article.
7) The driving motor 400 rotates forward, the screw rod 404 moves upwards for a certain distance to enable the fixing seat 202 to loosen the pull rod 305, the revolving door 300 is closed, the heating cavity 100 is closed, and dust is prevented from entering. The motion distance of the section does not need to be precisely controlled, and the motion time of the driving motor is controlled by the pcb control board.
The above is only a specific embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the concept of the present invention belong to the protection scope of the present invention. It should be noted that modifications and adaptations to the present invention may occur to one skilled in the art without departing from the principles of the present invention and are intended to be within the scope of the present invention.
