Detailed Description
The invention is further explained by the accompanying drawings.
As shown in fig. 1, the non-combustible electronic smoking set based on electromagnetic induction heating comprises a shell 5 with an opening 5a at the top center, a heat insulation layer 6 closely attached to the inner wall of the shell or coated on the inner wall of the shell, an electromagnetic induction coil 2 arranged at the upper part in the heat insulation layer, a smoke cartridge cup 1 arranged in the electromagnetic induction coil, and a metal rod 3 axially arranged and inserted into the smoke cartridge cup from the center of the bottom of the smoke cartridge cup. The bottom of the cigarette cup is provided with an air inlet hole so that air flow can enter the cigarette cup from the bottom. A circle of gap is reserved between the heat insulation layer and the electromagnetic induction coil, the center opening of the top of the shell is a tooth-shaped edge opening, as shown in figure 3, the tooth tip end of the tooth-shaped edge can be tightly abutted against an inserted heating non-combustible tobacco rod (smoke cartridge) to prevent the smoke cartridge from loosening, and the gap between the teeth becomes a channel for air flow to enter the shell. A section of cavity 4 is left between the top ends of the electromagnetic induction coil and the smoke cartridge cup and the top end of the shell. The surface of the electromagnetic induction coil 2 is coated with heat insulation materials, so that heat can be prevented from being conducted to the outside of the smoking set. A control circuit board 7 connected with the electromagnetic induction coil and a battery 8 for supplying power to the control circuit board are arranged at the lower part in the shell, and a button switch 9 connected with the control circuit is arranged on the shell. And a temperature sensor is arranged at the lower part of the metal rod and is connected with the control circuit board. The control circuit board is a PCBA board in the prior art, and can be directly purchased in the market. The metal rod 3 is a thin needle-shaped metal rod, the diameter of the metal rod is not more than 3mm, so that the tobacco rod which is not combusted by heating can be inserted conveniently. The shell is generally provided with an upper cavity and a lower cavity which are separated by a partition board, the electromagnetic induction coil, the smoke bomb cup and the metal rod are arranged in the upper cavity, the control circuit board and the battery are arranged in the lower cavity, and the electric lead of the electromagnetic induction coil penetrates through the partition board to be connected with the control circuit board.
When the present invention is used, as shown in fig. 4, a rod 10 of a tobacco which is not burned by heating is put into a cup of a cigarette from an opening 5a at the top of a case, and a metal rod is inserted from the center of the bottom of the rod. The button switch 9 is pressed, the control circuit board is electrified, the electromagnetic induction coil 2 is electrified immediately, the electromagnetic induction coil generates an alternating magnetic field, the alternating magnetic field generates vortex in the metal rod 3 and generates heat, the heat is uniformly transferred to the heating non-combustible tobacco rod, and the heating non-combustible tobacco rod is heated. As shown in the arrow direction in figure 2, the airflow enters from the gap between teeth on the opening of the tooth-shaped edge at the top of the shell, enters the gap between the heat-insulating layer and the electromagnetic induction coil through the cavity 4, passes through the air inlet hole at the bottom of the smoke bomb cup to rise, and passes through the heating non-combustible tobacco rod upwards. The smoker can only suck the tobacco through the mouth rod 10a which is heated and does not burn the tobacco rod. The temperature sensor monitors and controls the heating temperature of the metal bar, and prevents the heating temperature from being too high or too low. The temperature sensor is connected with the control circuit board, and when the temperature sensor detects that the heating temperature of the metal bar is too high, the power is automatically cut off. The thermal insulation layer can prevent the shell from being overheated, reduce heat loss in the smoke bomb cup and improve heating efficiency.
