Furthermore, a protective plate 4 is provided outside the housing 1, with suction through holes 5 located on the equipment mounting frame. These holes are closely arranged to provide air intake for the fan 2. The protective plate 4 located at the top of the smoke generating frame is provided with a smoke injection through hole 6 so that the generated smoke can be ejected from the smoke injection through hole 6.

[0034] The smoke jet fan 2 is horizontally connected at both ends to one end of the smoke jet box frame 1 and the dividing mounting rod 3 via fan mounting bases, and the air inlet of the smoke jet fan 2 corresponds to the air intake through hole 5, so as to draw air into the smoke jet box frame 1 from the air intake through hole 5. Alternatively, the smoke jet fan 2 is a duct fan.

[0035] Furthermore, a guide plate 7 is provided at the bottom of the other end of the smoke jet box frame 1. The guide plate 7 is arc-shaped and corresponds to the air outlet of the smoke jet fan 2, so as to guide the air ejected by the smoke jet fan 2 upward and improve the smoke jet efficiency.

[0036] The smoke heating element includes a smoke heating chamber 8 and a smoke heater, both of which are mounted on the smoke injection box frame 1. The smoke heating chamber 8 is rectangular in shape, with one side wall fixed to the partition mounting rod 3, and the smoke heating chamber is located within the smoke generating frame. The bottom surface of the smoke heating chamber 8 has elongated oxygen supply through-holes 10, with multiple through-holes 10 evenly spaced to allow air to enter the smoke heating chamber 8 for combustion. The bottom surface of the smoke heating chamber 8 is provided with a flame baffle plate 11, which is rectangular in shape. The flame baffle plate 11 is fastened to the bottom surface of the smoke heating chamber 8, covering the multiple elongated oxygen supply through-holes 10 within its groove to prevent flames emitted by the smoke heater from escaping from the smoke heating chamber 8 through the elongated oxygen supply through-holes 10.

The smoke barrier plate 20 is vertically fixed to the dividing mounting rod 3 to prevent the smoke generated by the smoke generator from entering the equipment mounting frame, further improving the efficiency of smoke ejection from the smoke spraying through-hole 6.

[0041] The booster pump 21 is fixedly mounted on the spray mounting plate 19. The e-liquid tank 22 is mounted on the partition mounting rod 3 via a housing mounting bracket, and the e-liquid tank 22 is connected through the liquid inlet of the booster pump 21. One end of the spray pipe 23 is connected through the liquid outlet of the booster pump 21, and the other end of the spray pipe 23 passes through the smoke barrier plate 20 and extends into the e-liquid evaporator 16. The atomizing nozzle 24 is connected through the other end of the spray pipe 23, and multiple atomizing nozzles 24 are evenly distributed on the spray pipe 23, and all multiple atomizing nozzles 24 spray towards the e-liquid evaporator 16. When the atomized e-liquid is sprayed onto the high-temperature e-liquid evaporator 16 and the evaporation rib plate 17, it will evaporate into smoke with a smaller particle size, thereby rapidly and significantly increasing the amount of smoke generated.

[0042] The smoke pellet generator includes a smoke pellet cage 25, which is hung on the side wall of the e-liquid evaporator 16. Multiple smoke pellet cages are evenly distributed on the side wall of the e-liquid evaporator. The smoke pellet cage 25 is used to hold the smoke pellets.
