The furnace body is internally provided with a drainage channel, the water inlet end of the drainage channel faces the air outlet hole 11 and is used for receiving liquid entering the furnace body from the air outlet hole 11, the water outlet end of the drainage channel faces the air inlet hole 51 and is used for guiding the liquid to the air inlet hole 51 and discharging the liquid out of the furnace body from the air inlet hole 51, so that the liquid is prevented from accumulating in the furnace body and burning other electric elements (such as the heating component 6 and a circuit board) in the electric heating furnace, the water inlet end and the water outlet end of the drainage channel receive water and drain water in a mode of facing the air outlet hole 11 and the air inlet hole 51, the air inlet and the air outlet of the air inlet hole 51 and the air outlet hole 11 are not influenced.

Furthermore, the periphery of the air inlet hole 51 is provided with a diversion trench 511 corresponding to the water outlet end of the drainage channel, so that the liquid can be guided and discharged more quickly, and the liquid is prevented from falling on a circuit board arranged near the bottom plate 5.

Further, the drainage channel includes a first water receiving tank 20 and a first drainage tank 21, the first water receiving tank 20 is disposed below the air outlet 11, the first drainage tank 21 is disposed on the first water receiving tank 20, a drainage water inlet 211 of the first drainage tank 21 faces upward and is communicated with the first drainage tank 21, and a drainage water outlet 212 of the first drainage tank 21 faces downward and is communicated with the air inlet 51. After entering the furnace body through the air outlet 11, the liquid flows downwards under the action of gravity, and the first water receiving tank 20 positioned below the air outlet 11 can smoothly receive the liquid, then flows into the first water discharging tank 21, flows to the air inlet 51 through the water discharging outlet 212 and is discharged out of the furnace body. At this time, the first water receiving tank 20 corresponds to a water inlet end of the drainage channel, and the drainage outlet 212 corresponds to a water outlet end of the drainage channel.

Further, be equipped with in the main part 1 and be the heat exchanger 2 that separates of basin form, separate heat exchanger 2 cover joint at the interior top of main part 1, heating element 6 is located and separates heat exchanger 2, and first water receiving tank 20, first drain tank 21 set up at the open-top periphery that separates heat exchanger 2, and liquid gets into the furnace body after, can discharge from separating heat exchanger 2 through first water receiving tank 20, first drain tank 21, liquid can not contact with heating element 6.

Further, the side in the first water receiving tank 20 outside is higher than the inboard side, can prevent that liquid from directly overflowing to the furnace body, avoids liquid and circuit board contact, the inside second water receiving tank 22 that is equipped with of heat shield 2, bottom are equipped with second water drainage tank 23, and the level of second water receiving tank 22 is higher than second water drainage tank 23, and is close to the inboard side of first water receiving tank 20, is equipped with on the second water drainage tank 23 and separates heat shield through-hole 231, separates heat shield through-hole 231 and inlet port 51 intercommunication. When the liquid entering the furnace body from the air outlet 11 is not discharged through the first water receiving tank 20 and the first water discharging tank 21 in time, the liquid overflows to the second water receiving tank 22 under the action of gravity, and after the second water receiving tank 22 receives the liquid, the liquid is discharged to the second water discharging tank 23 and flows to the air inlet 51 through the heat shield through hole 231, so that the liquid is discharged out of the furnace body. At this time, the heat shield through hole 231 corresponds to the water outlet end of the drain passage.

In addition, the heating assembly 6 generates high heat when working, and when a small amount of liquid enters the furnace body, the liquid can be rapidly heated and evaporated, which can be understood by those skilled in the art.

Further, be equipped with the drainage groove 221 towards second water receiving tank 23 on the second water receiving tank 22, can prevent effectively that liquid from having no directional flow everywhere in second water receiving tank 22, through setting up drainage groove 221 guide liquid unilateralism flow to second water receiving tank 23, further avoid liquid and the contact of heating element 6.

Further, a middle plate 3 may be disposed in the main body 1, the middle plate 3 is located above the bottom plate 5 and below the first drainage channel 21 and the second drainage channel 23, the middle plate 3 is provided with a plurality of raised surrounding edges 30 to form a middle plate water receiving channel, the middle plate water receiving channel is fully covered with middle plate through holes 31, and the drainage water outlet 212 and the heat shield through holes 231 respectively face the middle plate water receiving channel and are communicated with the air inlet 51 through the middle plate through holes 31. At this time, the middle plate through hole 31 corresponds to a water outlet end of the drainage channel. The middle plate 3 plays a role of converging, liquid discharged from the water discharge outlet 212 and the heat shield through hole 231 is converged and flows to the air inlet 51 through the middle plate through hole 31 so as to be discharged out of the furnace body, and the liquid can be effectively prevented from contacting with a circuit board positioned below the middle plate 3 and above the bottom plate 5.
