Through the above improvements, a threaded column is formed on the power input shaft, a connecting groove is formed on the ignition rod, and a connecting thread is formed on the connecting groove. The threaded column and the connecting groove are matched to enable the ignition rod and the power input shaft to be quickly connected.

[0012] Preferably, a sliding groove for the extrusion protrusion to slide is formed on the shell. Through the above improvement, the stability of the button during the sliding process is improved.

[0013] Preferably, the ceramic mounting seat and ceramic limit cover are made of high-temperature resistant ceramics, and the power input shaft and ignition rod are made of stainless steel. Through the above improvements, the power input shaft and ignition rod are made of stainless steel to ensure the conductive effect, and the ceramic mounting seat and ceramic limit cover are made of high-temperature resistant ceramics to ensure high-temperature resistance and insulation effects.

[0014] Preferably, an elastic element is provided on the PCB control board, and the elastic element abuts against the button so that the button always has a movement tendency away from the start switch. Through the above improvement, the automatic resetting of the button is achieved.

[0015] Preferably, the air inlet is arranged at an angle. Through the above improvements, the guidance of the airflow is improved, the ignition efficiency is increased, and the ignition delay can be reduced.

[0016] Compared with the prior art, the present invention has the following advantages and beneficial effects: The high-voltage module is driven by the PCB control board to work. When the high-voltage module increases the low voltage of the power supply unit to a high voltage, the current boosted by the circuit flows into the input shaft and is transmitted to the ignition rod. When the ignition rod is used to discharge, the arc breaks through the air, causing the molecules in the air to lose electrons, forming a mixture of cations and electrons. The burner generates a high-temperature plasma flame to achieve ignition. Compared with the traditional method that requires continuous reliance on gas, this application is free from gas dependence, is easy to operate and use, and is more convenient to carry, greatly improving the user experience.

These terms are only used to distinguish elements from each other for ease of understanding, and are not used to define any direction or order limitation.

[0020] like Figure 1-7 As shown, a handheld electronic flamethrower device includes a shell 1, a flamethrower 2 is provided on the shell 1, an ignition assembly 3 is provided in the flamethrower 2, a high-voltage module 11 is provided in the shell 1, a power supply unit 4 for powering the high-voltage module 11, and a PCB control board 5 for controlling the operation of the high-voltage module 11, and the high-voltage module 11 is connected to the power input end of the ignition assembly 3.

[0021] Furthermore, a fan 6 is provided in the housing 1 , and an air outlet end of the fan 6 is arranged toward the burner nozzle 2 . When the ignition assembly 3 discharges, the burner nozzle 2 generates a high-temperature plasma flame.

[0022] During the entire ignition process, the high-voltage module 11 is first driven by the PCB control board 5 to operate. When the high-voltage module 11 increases the low voltage of the power supply unit 4 to a high voltage, the current boosted by the circuit flows from the input shaft 8 and is transmitted to the ignition rod 9. When the ignition rod 9 discharges, the arc breaks through the air, causing the molecules in the air to lose electrons, forming a mixture of cations and electrons. The burner nozzle 2 generates a high-temperature plasma flame. The ceramic mount 7 is made of high-temperature resistant ceramics, which can prevent the arc from damaging the housing 1 and improve safety during use.

[0023] In addition, an air inlet slot is formed on the shell 1, and external wind enters the shell 1 through the air inlet slot, dissipating heat to the components inside the shell 1 while performing the flame-spraying function to ensure the service life of the internal components.

When the ignition rod 9 discharges, the arc breaks through the air, causing the molecules in the air to lose electrons, forming a mixture of cations and electrons, causing the burner nozzle 2 to generate a high-temperature plasma flame. The ceramic mount 7 is made of high-temperature resistant ceramics, which can prevent the arc from damaging the shell 1 and improve safety during use.

[0026] Specifically, a ceramic limit cover 10 is provided on the ceramic mounting base 7, and an air outlet slot 1.1 is formed on the ceramic limit cover 10.

When the fan 6 starts working, wind can flow into the air inlet 1.2 and be discharged through the air outlet slot 1.1, and the air inlet 1.2 is set toward the ignition rod 9, so that the flamethrower 2 can spray a uniform flame.

[0027] Furthermore, the ignition rod 9 is connected to the power input shaft 8 through a threaded connection. A threaded column is formed on the power input shaft 8, a connecting groove is formed on the ignition rod, and a connecting thread is formed on the connecting groove.

A starting switch 1.6 is formed on the PCB control board 5 and is arranged opposite to the pressing protrusion 1.5.

[0030] When ignition is required, the button 1.4 can be pressed to make the extrusion protrusion 1.5 on the button 1.4 squeeze the start switch 1.6, so that the PCB control board 5 controls the high voltage module 11 to work and ignite.

[0031] Furthermore, an elastic element 1.8 is provided on the PCB control board 5, and the elastic element 1.8 abuts against the button 1.4, so that the button 1.4 always has a movement tendency away from the start switch 1.6, thereby realizing automatic resetting of the button 1.4.

[0032] like Figure 3As shown, preferably, a sliding groove 1.7 for the extrusion protrusion 1.5 to slide is formed on the housing 1, thereby improving the stability of the button 1.4 during the sliding process.

[0033] like Figure 1 、 Figure 2 As shown, preferably, a gripping groove 1.3 for hand gripping is formed on the shell 1, and the gripping groove 1.3 and the button 1.4 are arranged on both sides of the shell 1 along the projection direction of the shell 1. When the hand is gripped on the gripping groove 1.3, the handle can be placed on the button 1.4, which improves the convenience of the user during use.

[0034] In other embodiments, the entire ignition device can be transferred to a lighter, and a high-voltage module 11 and an ignition assembly 3 are set in the housing 1 of the lighter to form a lighter that does not require the addition of fuel, thereby improving convenience in daily use.
