In this embodiment, the composite reservoir element 100 may further include a heating element 930, and the heating element 930 is mounted in the heating element connection port 1302 and directly connected to the controlled release portion 102 of the composite reservoir element 100. Alternatively, the heating element 930 may be indirectly connected to the controlled release portion 102 through a liquid guiding member, or directly connected to the liquid storage portion 101, thereby supplying the liquid to the heating element 930.

In this embodiment, the heating element connection port 1302 of the aerosol channel 1303 is communicated with the heating element 930, and the aerosol generated by atomization on the heating element 930 escapes through the aerosol channel 1303 and the aerosol outlet 1301. The aerosol channel 1303 may be integrally formed with the housing 110 of the liquid storage element, or may be formed separately, and the separately formed aerosol channel 1303 may be a plastic tube, a stainless steel tube, or a glass fiber tube. The aerosol passage 1303, when formed separately, can be removably attached to the reservoir housing 110. Alternatively, the composite reservoir element 100 may be provided with an atomizing chamber at the bottom thereof, and the heating element 930 is fitted in the atomizing chamber, which is in communication with the heating element connection port 1302.

Through a specific design, the composite liquid storage element 100 may be provided with a through hole or a small groove on the wall of the upper portion of the aerosol passage 1303, so that air can be communicated between the aerosol passage 1303 and the upper portion of the controlled release portion 102 through the through hole or the small groove. The controlled release portion vent 1021 may be provided in the top 818 of the reservoir component housing 110 at the top of the controlled release portion 102 or a non-tight fitting silicone plug may be used, by which the top or upper portion of the controlled release portion 102 is vented to the atmosphere.

As shown in fig. 1c and 1d, the controlled release part 102 may be a capillary medium, such as a capillary medium made of sponge or fiber bonding. The fiber can be filament or staple fiber, and the fiber has fineness of 1-30 denier, preferably 1.5-10 denier; the fibers may be monocomponent fibers such as polypropylene fibers, polyester fibers, polyamide fibers, and the like; the bicomponent fiber 2 with sheath-core structure or side-by-side structure can also be used, the sheath layer 21 and the core layer 22 of the bicomponent fiber with sheath-core structure can be concentric structure or eccentric structure, and the sheath layer 21 of the bicomponent fiber 2 with sheath-core structure can be polyethylene, polypropylene, polyester, copolyester, polyamide, polylactic acid, etc. The fibers may be bonded with a binder or plasticizer to form a capillary medium, preferably by thermal bonding of bicomponent fibers 2 in a sheath-core configuration. The cross-sectional shape of the controlled release portion 102 may be a circular ring, a semi-circular shape, a rectangular shape, a square shape, an elliptical ring shape, or other geometric shapes.

As shown in fig. 1b, the controlled release part 102 in this embodiment is preferably circular in cross section. The cross-section of the reservoir housing dividing wall 111 should match the outer contour of the cross-section of the controlled release portion 102, and the cross-section of the reservoir housing dividing wall 111 in this embodiment is shown in FIG. 1 e.

The controlled release portion 102 of this embodiment has a density of 0.03-0.2 g/cm 3, such as 0.03 g/cm³0.04 g/cm³0.05 g/cm³0.06 g/cm³0.08 g/cm³0.1 g/cm³0.12 g/cm³0.15 g/cm³0.18 g/cm³0.2 g/cm³Preferably 0.04 to 0.12 g/cm³. When the density is less than 0.03 g/cm³In this case, the strength of the controlled release part 102 is insufficient, and the manufacturing is difficult. When the density is more than 0.2 g/cm³In the case where the capillary force of the controlled release part 102 is too high, it is difficult to introduce external air into the liquid storage part 101 through the controlled release part 102, the pressure fluctuation range in the liquid storage part 101 is large, the stability of atomization is affected, and the liquid remaining rate after use is high. In the present embodiment, it is preferable to use the controlled-release section 102 made of the bicomponent fiber 2 of sheath-core structure by thermal bonding.

The heating element 930 is generally a bundle of glass fibers or cotton fibers wound with a heating wire, porous ceramics embedded with a heating wire, porous ceramics printed with a thick film heating element, or an ultrasonic atomizer, etc. The heating element 930 may be directly connected to the lower portion of the controlled release part 102, or indirectly connected through a liquid guide member, or directly connected to the liquid storage part 101. Heating element 930 may include wire 933 and wire leads 936 connected to an external power source.

The controlled release part 102 can have a higher density near the heating element 930, for example, the glass fiber bundles at two ends of the heating element 930 can be used to press the inner side of the controlled release part 102 and make it have a higher density locally, which is beneficial to the liquid in the controlled release part 102 to enrich near the heating element 930 and improve the stability of atomization.

The air inlet 1121 of the sealing portion of the assembled composite liquid storage element 100 is placed upward, a proper amount of liquid is injected into a liquid injection hole reserved in the sealing portion 112 of the lower portion of the liquid storage element shell, and then the liquid injection hole is closed. The liquid injection should be performed by exhausting air from the liquid reservoir 101 as much as possible or injecting liquid until part of the liquid is introduced into the controlled release portion 102, but the liquid introduced into the controlled release portion 102 is preferably not more than half of the liquid absorption capacity of the controlled release portion 102. After the liquid is injected, the air inlet 1121 of the sealing portion of the composite liquid storage element 100 is placed downward, the controlled release portion 102 absorbs a part of the liquid from the liquid storage portion 101 by using its capillary force to generate a negative pressure in the liquid storage portion 101, and when the controlled release portion 102 absorbs the liquid, the air in the controlled release portion 102 is discharged from the top or upper portion thereof.

In use, liquid on the heating element 930 is consumed by atomization and replenished from the liquid storage element 100, causing the negative pressure in the liquid storage portion 101 to rise, and the rising negative pressure pulls the liquid portion in the controlled release portion 102 back into the liquid storage portion 101. That is, the decrease of the liquid in the controlled release part 102 and the increase of the negative pressure of the liquid reservoir 101 are performed simultaneously, so that the liquid in the controlled release part 102 is gradually replaced by the external air from the top to the bottom. When the air level in the controlled release portion 102 drops to the partition wall opening 1113 of the liquid storage element casing partition wall 111, air is introduced into the liquid storage portion 101, thereby reducing the negative pressure inside the liquid storage portion 101.

This process is repeated until the liquid in the liquid reservoir 101 is used up. In the process of consuming the liquid in the liquid storage part 101, the negative pressure in the liquid storage part 101 fluctuates within a certain range but keeps relatively stable, so that the atomization process keeps relatively stable.

When the liquid in the liquid storage part 101 is used up and when the heating element 930 is directly or indirectly connected to the controlled release part 102, the liquid supply on the heating element 930 is entirely from the controlled release part 102. As the liquid in the controlled release portion 102 decreases, the amount of the liquid and the atomized aerosol supplied to the heating element 930 by the controlled release portion 102 is attenuated until the user stops using the aerosol.

Depending on the type of liquid to be atomized and the usage requirements, the negative pressure in the reservoir 101 can be changed by changing the capillary force of the controlled release portion 102 and changing the position of the partition wall opening 1113 of the reservoir housing partition wall 111, thereby changing the amount of liquid supplied to the heating element 930 and the amount of atomized aerosol.

As shown in fig. 1f, a partition wall groove 1111 may be formed on the side of the partition wall 111 of the cartridge case contacting the controlled release portion 102, the partition wall groove 1111 may be formed as a partition wall rib, so that air can be smoothly introduced into the reservoir 101 from the controlled release portion 102, and preferably, the partition wall groove 1111 or the partition wall rib is formed only on the side of the lower portion of the partition wall 111 of the cartridge case contacting the controlled release portion 102, so that the upper portion of the controlled release portion 102 is tightly fitted to the partition wall 111 of the cartridge case.

A gap is formed between a lower part of the controlled release portion 102 and the partition wall 111 of the liquid storage device case, so that air can smoothly enter the liquid storage portion 101 when the controlled release portion 102 is lowered to a certain height, and the risk of liquid leakage due to excessive air or premature air entering the liquid storage portion 101 is prevented. Preferably, the height of the partition wall recess 1111 or the partition wall bead is no more than one third of the height of the reservoir housing partition wall 111.

When the external environment is changed greatly, such as the ambient temperature is increased or the air pressure is decreased, the air in the liquid storage portion 101 expands, the negative pressure is decreased, and the liquid in the liquid storage portion 101 is partially discharged and absorbed by the release controlling portion 102, thereby preventing the liquid in the liquid storage element 100 from leaking. When the ambient temperature decreases, the air in the liquid reservoir 101 contracts, the negative pressure increases, and a part of the liquid returns from the controlled release portion 102 to the liquid reservoir 101.

The working principle of the composite liquid storage element 100 of this embodiment is the same as that of the first embodiment.
