A substitute cigarette includes a cigarette rod (10) and a simulated cigarette mouthpiece (20), the said cigarette rod (10) includes a power source and an electronic circuit, the said simulated cigarette mouthpiece(20) includes a simulated filter (25), a liquid storage chamber (28) and an atomizer (22), one end of the said atomizer (22) is connected to the output end of the power source in the cigarette rod(10), a column shape alloy sponge is provided in the atomizer (22)； the said simulated filter (25) includes a body (252) and a through hole (254) which runs through the axes of the body； the said liquid storage chamber (28) is housed in one end of the through hole (254) and includes a container (281) and a sealing membrane (30) for sealing the said container (281), some protrusions (284) are provided on the outer wall of the container (281)； when the simulated filter (25) mounts on the atomizer (22), the said sealing membrane (30) is thrust by the said column shape alloy sponge and ruptured, the liquid in the container (281) seeps into the alloy sponge in the atomizer (22) and is atomized into gas by the atomizer (22), the atomized gas passes through the interspace between the protrusions (284) and the simulated filter (25) and flows into the mouth of the user in the end.
