The bottom of the ion head 422 is provided with an arc-shaped chamfer 4223; multiple tests show that the arc-shaped chamfer 4223 can effectively prolong the service life of the ion head 422. When a plurality of ion pins 42 are simultaneously installed on the furnace head, the arc-shaped chamfer 4223 at the bottom of the ion head 422 can prevent high-voltage arc discharge between the ion heads 422 on adjacent ion pins 42 (the voltage exceeds the tolerance of air to ionize the air into a conductor, namely, an arc is generated, the arc generally bypasses an insulator and is generated along the surface of the insulator, so that the insulator can be damaged, for example, the high temperature of the arc can melt or crack the insulator, for example, the rated short-circuit breaking current 20KA is shown on a switch, the arc-extinguishing heat element action of a short-circuit tripping contact in 20KA is shown to be effective, and the arc-extinguishing heat element action beyond the limit tripping joint is not ensured, so that the arc discharge can be generated). The mounting groove 4221 is a circular groove, the support bar 421 is provided with a first limit ring 4213, and the outer diameter of the first limit ring 4213 is larger than the inner diameter of the mounting groove 4221; the first limit ring 4213 can prevent the top of the first mounting protrusion 4212 from directly contacting the bottom of the first mounting groove 4221, so as to prevent the first mounting protrusion 4212 from being sintered and connected with the groove bottom of the first mounting groove 4221 at a high temperature, and prevent the ion head 422 from being detached from the support rod 421 quickly. The support bar 421 is provided with a plurality of heat dissipation rings 4214, a gap is formed between adjacent heat dissipation rings 4214, and a gap is formed between adjacent heat dissipation rings 4214 to increase the heat dissipation area of the ion needle 42, ensure the heat dissipation effect of the ion head 422, and increase the service life of the ion needle 42. Of course, other heat dissipation structures may be disposed on the ion pin 42 to prolong the service life of the ion pin 42.

Further, referring to fig. 23 to 24, as another embodiment of the electric flame stove according to the present invention, the supporting rod 421 is connected to the base 41 by a screw thread 4211, a second position-limiting ring 4215 is disposed on the supporting rod 421, and the second position-limiting ring 4215 is disposed on a side of the screw thread 4211 close to the ion head 422, so as to prevent the supporting rod 421 from being inserted into the base 41 to an excessively large depth.

Further, referring to fig. 21-22, as another embodiment of the electric flame stove provided by the present invention, a detection supporting platform 47 is disposed on the base 41, a detection groove 471 is disposed on the detection supporting platform 47, and an induction component 8 is disposed in the detection groove 471; the sensing assembly 8 comprises a sensing switch arranged in the detection groove 471, a sliding part 81 which is used for contacting with the pot 9 and triggering the sensing switch, and a compression spring 82 arranged between the sliding part 81 and the detection support platform 47; the slider 81 is slidably attached to the detection support table 47. When the pot 9 is placed on the burner, the pot 9 contacts the sliding member 81 and applies force to the sliding member 81 to enable the sliding member 81 to slide relative to the detection support platform 47 and compress the compression spring 82, the sliding member 81 slides for a certain distance to trigger the induction switch, the transformer 3 of the electric flame stove supplies high pressure to the ion needle 42 and generates electric flame at the ion head 422, when the pot 9 is taken away, the compression spring 82 is reset to push the sliding member 81 open, the triggering state of the sliding member 81 on the induction switch is released, and the transformer 3 of the electric flame stove stops supplying high pressure to the ion needle 42. Further, the operation of the ion needle 42 can be stopped as long as the pot 9 leaves the furnace end in the normal use process of the electric flame stove, and the potential safety hazard of high pressure at the ion head 422 of the ion needle 42 is avoided.

Further, referring to fig. 21-22, as another embodiment of the electric flame stove provided by the present invention, the sensing assembly 8 further includes a fixed cylinder 83 fixedly installed in the detection groove 471, a guide cylinder 84 inserted into the fixed cylinder 83 and threadedly connected to the fixed cylinder 83, and a seventh sealing ring 85 disposed between the fixed cylinder 83 and the detection support platform 47. The guide cylinder 84 is connected with the fixed cylinder 83 by screw threads, so that the assembly of the induction component 8 is convenient.
