[0034] The housing 1 is provided with a suction port 14. The bottom cover 3 is provided with an air inlet 31. The air inlet 31 and the suction port 14 form an air flow channel 15 therebetween. The bottom cover 3 includes a leakage prevention protrusion 32 disposed at the air inlet 31. The leakage prevention protrusion 32 is provided with at least one leakage prevention hole 321 in communication with the air inlet 31. The leakage prevention protrusion 32 is used for guiding the leakage of the tobacco tar from the oil storage cavity 13, so that the tobacco tar flows along the surface of the leakage prevention protrusion 32. When the tobacco tar flows to the leakage prevention hole 321, an oil film is formed thereon, which is used for isolating the leakage prevention hole 321 from the air inlet 31.

[0035] Based on the above-mentioned arrangement, the leakage prevention protrusion 32 is arranged at the air inlet 31. When the amount of tobacco tar stored in the oil storage body 7 in the oil storage cavity 13 is excessive, the tobacco tar in the oil storage cavity 13 will drip onto the air inlet 31. The leakage prevention protrusion 32 guides the leakage of the tobacco tar, so that the tobacco tar flows along the surface of the leakage prevention protrusion 32. The leakage of the tobacco tar from the air inlet 31 is effectively avoided. When the leakage prevention protrusion 32 guides the leakage of the tobacco tar, an oil film is formed when the tobacco tar passes through the leakage prevention hole 321. The oil film can isolate the communication between the leakage prevention hole 321 and the air inlet 31 within a certain air pressure range. Even if the tobacco tar in the oil storage cavity 13 leaks out subsequently, the direct leakage of the tobacco tar from the air inlet 31 is effectively prevented, so that the leakage and waste of the tobacco tar are avoided.

The leakage prevention groove 33 is used for accommodating the tobacco tar. When the leakage prevention protrusion 32 guides the leakage of the tobacco tar, the tobacco tar flows along the surface of the leakage prevention protrusion 32 to the groove bottom of the leakage prevention groove 33. The leakage prevention groove 33 can receive the tobacco tar. The leakage prevention protrusion 32 protrusively extends from the groove bottom of the leakage prevention groove 33 to the direction of the groove opening. The leakage prevention groove 33 can accommodate a certain amount of tobacco tar, so that the leakage of the tobacco tar is effectively prevented.
