As a suitable material selection, the elastic sealing member 102a is preferably made of a flexible material, for example, in some examples, the elastic sealing member 102a can be made of silicone, thermoplastic elastomer (Thermo-Plastic-Elastomer) or thermoplastic rubber (Thermo-Plastic-Rubber) material prepared.

The elastic seal 102a includes an upstream end 102a1 (an end away from the liquid storage chamber A), a downstream end 102a2 (an end close to the liquid storage chamber A), a body 102a3 extending from the upstream end 102a1 to the downstream end 102a2; A sleeve portion (not shown) between the cavities 102a4 is at least partially clamped between the inner wall of the main body 101a and the outer side wall of the bottom cover 106a, the downstream end 102a2 and the inner wall of the main body 106a Contact is maintained to form a seal and define at least part of reservoir A.

In a preferred implementation, a first rib (not shown) is provided on the outer wall of the body 102a3 near the upstream end 102a1, and a second rib (not shown) is provided on the outer wall of the body 102a3 near the downstream end 102a2. , a good sealing effect can be formed by the first rib and the second rib.

The main body 102a3 is provided with a receiving cavity 102a4 and a liquid channel 102a5. The downstream end 102a2 has an opening, and the receiving chamber 102a4 is exposed to the opening, that is, the receiving chamber 102a4 communicates with the opening. The atomization assembly can be assembled or accommodated in the receiving cavity 102a4 through the opening of the downstream end 102a2, and the liquid channel 102a5 communicates with the receiving cavity 102a4 and the liquid storage cavity A, so that the liquid matrix can be transferred to the liquid guiding element 104a through the liquid channel 102a5.

In a preferred implementation, another liquid-guiding element (not shown), such as: liquid-guiding cotton, can be arranged in the liquid channel 102a5, to prevent the liquid matrix from directly flowing to or passing to the liquid-guiding element 104a quickly, and to regulate the liquid matrix. A function of the velocity delivered to the liquid conducting element 104a. In a further preferred implementation, another liquid-guiding element (not shown) can be arranged on the elastic sealing member 102a, such as: hard organic cotton, and the hard organic cotton has the effect of basically sealing the opening of the liquid storage chamber A, and is used to avoid The liquid matrix directly flows out from the opening, so that the liquid matrix in the liquid storage chamber A can basically only permeate away slowly through the liquid guiding element, and then transfer to the liquid guiding element 104a through the liquid channel 102a5.

A part of the outer surface of the liquid guiding element 104a is kept in contact with the inner wall (or inner wall surface) of the receiving cavity 102a4, so as to block the flow of the liquid matrix towards the bottom cover 106a through the liquid channel 102a5, and then between the liquid storage cavity A and the air flow channel.

In the example of Fig. 3 to Fig. 10, the upstream end of aerosol channel 102a6 is an open end (that is, communicates with accommodating chamber 102a4), and abuts with connection part 104a5; Of course, the upstream end of aerosol channel 102a6 can also be closed end and abuts against the connecting portion 104a5.

On the second side, the heating element 103a is disposed on the second side; the upstream end of the aerosol channel 102a6 is a closed end (that is, separated from the receiving cavity 102a4 ) and kept at a distance from the first side. A gap is provided between the closed end and the first face of the porous body 104b. In some implementations, there is a laterally extending groove (not shown) on the surface of the closed end opposite the first face of the porous body 104b.

In this way, the liquid matrix can pass through the gap between the closed end and the porous body 104b to the middle part of the porous body 104b (shown by the arrow in FIG. 10 ), avoiding the problem of dry burning caused by insufficient liquid supply.

In another example, the atomizing surface of the liquid guide element, that is, the surface combined with the heating element faces the liquid storage chamber A, and the liquid absorption surface faces away from the liquid storage chamber A, so that the atomization surface is closer to the aerosol channel than the liquid absorption surface. At this time, the upstream end of the aerosol channel can be an open end and maintain fluid communication with the atomizing surface of the liquid guiding element.

There is a gap between the second side wall 104a2 and the inner wall of the elastic sealing member 102a, thereby respectively forming a first airflow channel and a second airflow channel. In the process of suction, after the air enters the atomization chamber bounded by the atomization surface 104a7, the aerosol is carried across the liquid guide element 104a or the receiving chamber 102a4 from the airflow channel (that is, the aerosol flows through the liquid guide element 104a). The side surface between the upper and lower surfaces), and then output to the aerosol channel 102a6 near the central part of the smoke output pipe 1011a, and then output to the smoke output pipe 1011a. In a preferred implementation, the inner wall (or inner wall surface) of the elastic seal 102a has a groove 102a7 to define the air flow channel with the first side wall 104a1 or the second side wall 104a2; one end of the groove 102a7 is close to the elastic seal 102a The upstream end 102a1 is set, and the other end extends along the longitudinal direction of the main body 101a and crosses the liquid guiding element 104a or the receiving cavity 102a4. It can be seen from the figure that the inner wall of the elastic sealing member 102a has two correspondingly arranged grooves 102a7; thus, Each groove 102a7 forms an air flow channel with the side surface of the liquid guiding element 104a.

Referring further to FIG. 9 , an airflow groove 102a8 is disposed in the elastic sealing member 102a, and the airflow groove 102a8 is arranged along the receiving chamber 102a4 and the liquid passage 102a5 to form an air pressure balance passage. The air entering the atomization chamber can flow into the liquid storage chamber A through the airflow groove 102a8, thereby relieving the negative pressure in the liquid storage chamber A.

The liquid guiding element 104 is made of flexible strip or rod-shaped fiber material, such as cotton fiber, non-woven fabric fiber, sponge body and the like.

The liquid guiding element 105 is made of elastic organic porous material, which exhibits moderate flexibility and rigidity. In practice, the fluid guiding element 105 has a modulus of elasticity or stiffness that is smaller than that of the body 101 or the material defining the reservoir A, and greater than that of the fluid guiding element 104 .

Fig. 18 shows a schematic structural view of an elastic seal 102a in another embodiment; the difference from the elastic seal 102a illustrated in Fig. The hole 102a82 and the through hole 102a82 extend longitudinally from the downstream end 102a2 to the receiving cavity 102a4 and are physically separated from the liquid channel 102a5. In this way, the air entering the atomization chamber can flow into the liquid storage chamber A through the airflow groove 102a81 and the through hole 102a82, thereby relieving the negative pressure in the liquid storage chamber A. After the liquid guiding element 104a is assembled on the elastic seal 102a, a part of the outer surface of the liquid guiding element 104a is kept in contact with the inner wall (or inner wall surface) of the receiving chamber 102a4, so that the air pressure balance channel and the liquid channel 102a5 are completely physically separated, thereby The air bubbles formed by the entry of external air from the air pressure balance channel can directly escape into the liquid storage chamber A, which can prevent the bubbles from accumulating in the liquid channel 102a5 and causing The problem that the liquid substrate is not smoothly discharged through the liquid channel 102a5.

It should be noted that the air pressure balance channel is not limited to the two situations shown in Fig. 9 and Fig. 18 . In other examples, the air pressure balance channel can also extend from the downstream end 102a2 to the groove 102a7 or the aerosol channel 102a6, which can be slotted or provided with a through hole; the air pressure balance channel can also be partially arranged between the elastic seal 102a and the main body 101a between.
