In a preferred embodiment of the present invention, the cross-sectional area of the channel 103a is smaller than or equal to the area of the smoke solution replenishing surface of the porous body 10, so that the smoke solution in the liquid storage cavity 104 is favorably adsorbed by the porous body 10, the excessive smoke solution is prevented from leaking into the accommodating cavity 105 of the liquid replenishing device, and the liquid replenishing device can be kept clean. Wherein, the porous body 10 is contacted with the separator 103, and the smoke liquid supplementing surface is the surface of the porous body 10 contacted with the separator 103.

Referring to fig. 13, a liquid guiding layer 106 is further provided on the partition 103, and is configured to contact the porous body 10 and the partition 103, respectively, and to be capable of adsorbing the smoke liquid in the liquid storage chamber 104. Wherein, porous body 10 and drainage layer 106 contact, and the cigarette liquid replenishment face is the surface that porous body 10 and drainage layer 106 contact. The porous body 10 is in contact with the liquid-conductive layer 106, and can absorb and replenish the liquid smoke through the liquid-conductive layer 106. In a preferred embodiment of the present invention, the liquid-guiding layer 106 is made of a material that is permeable to liquid. Liquid-guiding layer 106 may be porous, such as cotton, porous ceramic, low-foaming resin, or may have a fibrous structure.

Referring to fig. 13, when the cover 102 closes the inner cavity, one end of the porous body 10 abuts against the cover 102, and the other end abuts against the cigarette liquid contact surface. When the liquid guide layer 106 is not provided, the porous body 10 is in contact with the separator 103, and the smoke contact surface is a surface of the separator 103 in contact with the porous body 10. When the liquid-conductive layer 106 is provided, the porous body 10 is in contact with the liquid-conductive layer 106, and the liquid-smoke contact surface is a surface of the liquid-conductive layer 106 in contact with the porous body 10. After the cover 102 is opened, the porous body 10 can be taken out and put in. When the cover 102 is closed, the porous body 10 cannot move freely.

Referring to fig. 13 and 15, as a preferred embodiment of the present invention, the cover 102 is provided with an elastic pressing pad 107 for pressing the porous body 10 when the cover 102 closes the inner cavity, and one end of the porous body 10 abuts against the elastic pressing pad 107 and the other end abuts against a cigarette liquid contact surface. After the elastic pressure pad 107 is arranged, the porous body 10 can be ensured to be fully contacted with a tobacco juice contact surface, and the limiting effect can be achieved while full liquid supplement is realized. The number of the elastic pressure pads 107 is not limited, and in the present embodiment, the number of the elastic pressure pads 107 is consistent with the number of the porous bodies 10, and corresponds to one another. Two porous bodies 10 are shown in fig. 15, and elastic pressure pads 107 are provided in one-to-one correspondence with the two porous bodies 10.

The invention also provides an aerosol-generating device assembly comprising: the porous body 10 of any of the previous embodiments, storing tobacco smoke; the heating element 20 according to any of the preceding embodiments, wherein the porous body 10 is capable of transporting the stored tobacco juice to the heating element 20, and the heating element 20 is configured to atomize the tobacco juice transported by the porous body 10 after being energized; the fluid infusion device according to any of the above embodiments is used for infusing tobacco fluid to the porous body 10.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that the foregoing is a more detailed description of the invention, taken in conjunction with the specific embodiments thereof, and that no limitation of the invention is intended thereby. Various changes in form and detail, including simple deductions or substitutions, may be made by those skilled in the art without departing from the spirit and scope of the invention.
