In specific implementation, part of the material in the oil tank 10 may be removed to form the accommodating chamber, and the oil tank 10 with the accommodating chamber may also be manufactured in an integrated molding manner. The opening of the receiving chamber, from which the tobacco tar is injected into the receiving chamber during the production of the cartridge, opens on the side facing away from the smoking opening 21.

In this embodiment the mouthpiece 20 is fitted to the exterior of the tank 10 as part of the outer shell of the cartridge, and the user inhales with the mouthpiece 20 contained in the mouth during use, and the atomised smoke passes from the mouthpiece 20 through the mouthpiece 21 into the user's mouth.

The refrigerating device preferably adopts a semiconductor refrigerating sheet 40, the semiconductor refrigerating sheet is formed by mutually arranging a plurality of N-type and P-type semiconductors, and the control of the refrigerating effect of the semiconductor refrigerating sheet 40 can be realized by controlling the input current. The semiconductor refrigeration piece 40 does not need any refrigerant when refrigerating, can continuously work, has no pollution source, does not have a rotating part, does not generate a rotation effect, does not have a sliding part, does not have vibration and noise when working, and has long service life. In other embodiments, the refrigeration device can also adopt other devices such as loop heat pipes, heat pumps and the like. The refrigerating device comprises a cold end for generating cold and a hot end for generating heat, namely, one end of the cold end generates cold, the other end generates heat, the semiconductor refrigerating sheet 40 is usually in a sheet shape, one surface of the semiconductor refrigerating sheet 40 faces the oil tank 10, and the other surface of the semiconductor refrigerating sheet 40 is back to the oil tank 10.
