It should be noted that, because the second sealing member 122 is configured to form the bottom of the liquid storage bin 13, a surface of the second sealing member 122 facing away from the base 121 is flush with the upper end surface of the housing 60, so that the situation that the second sealing member 122 protrudes from the upper end surface of the housing 60 can be avoided, at this time, a boundary line between the upper end surface of the housing 60 and the second sealing member 122 and a boundary line between the upper end surface of the second sealing member 122 and the atomized liquid can be seen through the housing 11 from the outside, which results in more visual and organoleptic layers and is not brief; the situation that the second sealing member 122 is lower than the upper end face of the housing 60 can be avoided, and at this time, the parting line between the upper end face of the second sealing member 122 and the atomized liquid and the inner side face of the housing 60 between the upper end face of the housing 60 and the upper end face of the second sealing member 122 can be seen through the housing 11 from the outside, so that the visual sense has more layers and is not simple.

The second liquid guiding layer 322 is stacked on a surface of the first liquid guiding layer 321 facing away from the heating element 31, so that atomized liquid absorbed by the second liquid guiding layer 322 can be uniformly transferred to the first liquid guiding layer 321. In order to overcome the defect of poor high temperature resistance of the traditional liquid absorbing member, the first liquid guiding layer 321 is a heat-resistant layer arranged between the heating member 31 and the second liquid guiding layer 322, the first liquid guiding layer 321 serving as the heat-resistant layer is made of a high temperature-resistant material, and meanwhile, the first liquid guiding layer 321 serving as the heat-resistant layer has good liquid guiding performance, so that the whole liquid guiding member 32 has better high temperature resistance and good liquid guiding performance and is not easy to burn. In addition, the first liquid guiding layer 321 serving as the heat-resistant layer has good liquid storage performance, namely the liquid storage amount of the first liquid guiding layer 321 is 35-50 mg/min, meanwhile, the liquid guiding rate of the second liquid guiding layer 322 is larger than that of the first liquid guiding layer 321, so that the defects of low liquid absorption rate and low liquid guiding rate of the traditional liquid absorption piece can be effectively overcome, the liquid absorption rate and the liquid guiding rate of the liquid guiding piece 32 can meet the normal atomization work of the heating piece 31, the situation that the liquid absorption rate and the liquid guiding rate of the liquid absorption piece are too low can not occur, and the problem that the heating piece 31 is dry-burned due to untimely liquid supply of the liquid absorption piece can be well solved.

It should be noted that, in some specific application scenarios, the heat-resistant layer may be, but is not limited to, flax cotton. The process of carrying out transverse liquid guiding test on flax cotton comprises the following steps: the single-layer flax cotton is vertically hung, the flax cotton is contacted with the atomized liquid in the vertical direction, and the height (unit is mm/3 s) of the single-layer flax cotton wetted by the atomized liquid within 3 seconds is captured by a camera. After the atomized liquid climbs along the vertically suspended flax cotton for 1 minute, the atomized liquid is removed, and the liquid storage amount (in mg/min) of the heat-resistant layer is reflected by examining the quality of the atomized liquid adsorbed by the single-layer flax cotton. According to the embodiment of the utility model, by the transverse liquid guiding testing method, the liquid storage amount of the first liquid guiding layer 321 can be measured to be 35-50 mg/min, and the transverse liquid guiding rate of the first liquid guiding layer 321 is 3-3.5 mm/3s.

It will be appreciated that in some of these specific applications, the second liquid-guiding layer 322 may be, but is not limited to, porous cotton such as wood pulp cotton or non-woven fabric, and the grammage of the second liquid-guiding layer 322 is 45-55 g/m ² Therefore, the second liquid guiding layer 322 has a higher liquid absorbing rate and liquid guiding rate than the first liquid guiding layer 321, so that the liquid absorbing rate and liquid guiding rate of the liquid guiding member 32 can be increased, and the liquid guiding member 32 can rapidly transmit the atomized liquid to the heating member 31.

Compared with the prior art, the liquid guide member provided by the embodiment of the utility model has the advantages that the first liquid guide layer 321 is arranged between the heating member 31 and the second liquid guide layer 322, the first liquid guide layer 321 is a heat-resistant layer made of a high-temperature-resistant material, and the first liquid guide layer 321 serving as the heat-resistant layer is contacted with the heating member 31, so that the high-temperature resistance of the liquid guide member 32 can be improved, and the burnt smell of the liquid guide member 32 can be effectively prevented. In addition, the liquid storage amount of the first liquid guiding layer 321 is 35-50 mg/min, and the liquid guiding rate of the second liquid guiding layer 322 is greater than that of the first liquid guiding layer 321, so that the liquid absorbing rate and the liquid guiding rate of the liquid guiding piece 32 can be accelerated, the liquid guiding piece 32 can rapidly transmit atomized liquid to the heating piece 31, and dry burning of the heating piece 31 due to insufficient liquid supply or infusion interruption is avoided, so that the burning of the liquid guiding piece 32 is further effectively prevented.

In some embodiments, a first liquid-guiding layer 321 is arranged between the heating element 31 and the second liquid-guiding layer 322, and the gram weight of the first liquid-guiding layer 321 is 54-66 g/m ² Since the first liquid guiding layer 321 is a heat-resistant layer arranged between the heating element 31 and the second liquid guiding layer 322, the first liquid guiding layer 321 as the heat-resistant layer is made of a high temperature resistant material, so that the whole liquid guiding element 32 has better high temperature resistance and no scorching problem.

Referring to fig. 8 in combination, in other embodiments, two first liquid guiding layers 321 are disposed between the heat generating element 31 and the second liquid guiding layer 322, and the first liquid guiding layers 321 are heat resistant layers disposed between the heat generating element 31 and the second liquid guiding layer 322, and the first liquid guiding layers 321 as heat resistant layers are made of heat resistant materials, so that the heat resistance of the whole liquid guiding element 32 can be further improved by disposing two heat resistant layers between the heat generating element 31 and the second liquid guiding layer 322. It should be noted that, since the liquid guiding rate of the first liquid guiding layer 321 as the heat-resistant layer is smaller than that of the second liquid guiding layer 322, when three or more heat-resistant layers are provided between the heat generating element 31 and the second liquid guiding layer 322, the heat resistance of the entire liquid guiding element 32 can be enhanced, but the liquid guiding performance of the entire liquid guiding element 32 is greatly reduced, and dry heating of the heat generating element 31 due to insufficient liquid supply or interruption of transfusion is likely to occur.
