[0034] like Figure 3 and Figure 4 As shown, the oil storage bin 112 is located in the atomizer housing 11, and the lower part of the oil storage bin 112 is an oil storage bin sealing silica gel 15; a shaping frame 16 is arranged inside the oil storage bin sealing silica gel 15, so that the oil storage bin sealing silica gel 15 is closely attached to the inner wall of the atomizer housing 11 to form a closed space for storing the smoke oil; the upper part of the atomizer housing 11 is a suction nozzle end 111 (the suction nozzle end 111 is a flat tongue-shaped structure for the convenience of the smoker to inhale), and the lower part is through the card slot 113 thereon (see Figure 4 ) and the buckle 1703 on the metal connector 17 (see Figure 7 ) for clamping, and a sealing ring 1705 (see Figure 3 and Figure 7 ), the card slot 113 and the buckle 1703 are four respectively; the sealing ring 1705 can be one, two or more to ensure the sealing effect; the bottom of the metal joint 17 is provided with an air inlet 1702 and a pin 1704 that can be connected to electricity and magnetic attraction (see Figure 2 ); The space between the metal joint 17 and the oil tank sealing silica gel 15 is the smoke oil recovery tank 1701 (see Figure 3 and Figure 7), the oil recovery bin 1701 is provided with oil absorbing cotton 19; the height of the air inlet 1702 is higher than the thickness of the oil absorbing cotton 19, to prevent the oil from flowing out directly from the air inlet 1702; at the same time, when the air flows into the oil recovery bin 1701 from the air inlet 1702, the air will not flow to the liquid surface of the oil recovery bin 1701, to prevent the gas from carrying oil and affecting the taste. The metal joint 17 is generally non-detachably connected to the atomizer housing 11.
[0035] like Figure 5 As shown, the interdigital transducer 1201 is connected to an electrode 1204 ; the electrode 1204 is located on the lower end surface of the surface acoustic wave atomization core 12 and passes through the hole on the oil tank sealing silicone 15 to be in electrical contact with the ejector pin 1704 .

[0038] If a small amount of the smoke oil that enters the atomization area 1202 through the oil-guiding cotton 18 and the oil-guiding slit 1203 is not atomized, it enters the smoke oil recovery bin 1701 under the action of gravity and is absorbed by the oil-absorbing cotton 19 and then recovered; this will not cause the smoke oil to leak and contaminate the battery and circuit board in the cigarette rod 2.
[0039] The embodiments of the present invention are described in detail above. For ordinary technicians in this field, according to the ideas provided by the present invention, there will be changes in the specific implementation methods, and these changes should also be regarded as the protection scope of the present invention.
