Description

Technical Field

[0001] The invention relates to a composite liquid storage element and an aerosol dispersing device, in particular to a composite liquid storage element for providing liquid for a heating element. Background Art

[0002] Aerosol dispensing devices are widely used in various fields of daily life, such as electronic cigarettes, electric aromatherapy, etc. Aerosol dispensing devices include a liquid storage element and a heating element. The liquid storage element provides liquid for the heating element. When the airflow passes through the atomization device, the heating element is heated, and the liquid is atomized and carried out by the airflow. The common liquid storage element is a cavity. In order to reduce leakage of the liquid in the cavity during storage and transportation but to be smoothly atomized during use, the usual composite liquid storage element or aerosol dispensing device is designed with a complex structure. Some liquid storage elements are filled with liquid adsorption materials, such as non-woven fabrics. The liquid release of the liquid storage element filled with liquid adsorption materials is severely attenuated during use, the experience is poor, and it is also easy to leak. In addition, the amount of residual liquid in the adsorption material after use is large, and the liquid waste is serious. Summary of the invention

[0003] In order to solve the problems existing in the prior art and effectively solve the leakage of liquid while maintaining a smooth atomization process, the present invention proposes a composite liquid storage element, which includes a liquid storage element shell, a liquid storage element shell partition wall, a liquid storage part, a controlled release part and a partition wall opening arranged near the lower part of the liquid storage part, and the liquid storage part and the controlled release part are separated by the liquid storage element shell partition wall and connected through the partition wall opening.

[0004] Furthermore, the controlled-release portion has a controlled-release portion vent hole connected to the atmosphere.

[0005] Furthermore, the composite liquid storage element also includes a sealing portion at the lower portion of the liquid storage element shell.

[0006] Furthermore, the lower sealing portion of the liquid storage element housing includes a sealing portion protrusion facing the liquid storage portion.

[0007] Furthermore, a liquid injection hole is provided at the lower sealing portion of the liquid storage element shell.

[0008] Furthermore, the composite liquid storage element further comprises a heating element, and the heating element is directly connected to the controlled release portion, or directly connected to the liquid storage portion, or indirectly connected to the controlled release portion via a liquid guiding element.

[0009] Furthermore, the wall surface of the liquid storage element shell partition wall in contact with the controlled release portion is provided with a partition wall groove or a partition wall convex rib extending from the bottom end to the top end of the liquid storage element shell partition wall, and the height of the partition wall groove or the partition wall convex rib does not exceed one third of the height of the liquid storage element shell partition wall.

[0010] Furthermore, the controlled release portion is a capillary medium.

[0011] Furthermore, the capillary medium is made of sponge.

[0012] Furthermore, the capillary medium is made of fibers bonded together.

[0013] Furthermore, the fiber is a bicomponent fiber with a sheath-core structure, and the sheath layer and the core layer are a concentric structure or an eccentric structure.

[0014] Furthermore, the density of the controlled release portion is 0.03 g / cm 3 -0.2 g / cm 3 .

[0015] Furthermore, the composite liquid storage element further includes a heating element, and the density of the controlled release portion near the heating element is higher than that of other portions.

[0016] Furthermore, the controlled release portion includes a density increasing portion.

[0017] Furthermore, a liquid injection hole is reserved at the top of the liquid storage part.

[0018] Furthermore, the controlled release portion controls the release of liquid in the composite liquid storage element.

[0019] Furthermore, the aerosol dispensing device includes the above-mentioned composite liquid storage element.

[0020] Normally, the controlled release part absorbs a portion of the liquid but is in an unsaturated state. Since the liquid storage part is connected to the controlled release part near the lower part, the capillary force of the controlled release part forms a certain negative pressure in the liquid storage part, thereby effectively preventing the liquid in the liquid storage element from leaking. During use, as the liquid in the liquid storage element is consumed, the negative pressure in the liquid storage part increases, the liquid in the controlled release part decreases, and the external air can be introduced into the liquid storage part through the controlled release part, effectively controlling the pressure fluctuation in the liquid storage part, so that the liquid storage part and the controlled release part can smoothly supply liquid to the heating element, ensuring the stability of the atomization process. If the external environment changes significantly during storage, transportation or use, such as the ambient temperature increases, the air in the liquid storage part expands, the negative pressure decreases, and the liquid in the liquid storage part tends to leak outward. At this time, the controlled release part uses its capillary force to absorb liquid from the liquid storage part, thereby maintaining the negative pressure in the liquid storage part at a certain level, avoiding liquid leakage in the liquid storage element.

[0021] The amount of liquid in the controlled release part accounts for a small proportion of the total amount of liquid in the composite liquid storage element, which is conducive to the full utilization of the liquid during the atomization process and reduces the residual proportion of liquid in the controlled release part after use. The composite liquid storage element and the aerosol dispensing device using the composite liquid storage element have a simple structure and are easy to assemble automatically. By controlling the capillary force of the controlled release part, the composite liquid storage element is adapted to the requirements of different aerosol dispensing devices. After the liquid is used up, the liquid injection hole at the top or bottom of the liquid storage part of the composite liquid storage element can be used to inject liquid again, so as to reuse resources.

[0022] The composite liquid storage element of the present invention can be applied to the atomization of various electronic cigarette liquids, and is also applicable to the atomization of solutions such as cannabidiol, and is also applicable to the atomization of electric mosquito coil liquids and air fresheners.

[0049] First embodiment

[0051] like Figure 1a and 1b As shown, the composite liquid storage element 100 according to the first embodiment of the present invention includes a liquid storage element shell 110, a liquid storage element shell partition wall 111, a liquid storage portion 101, a controlled release portion 102 and a partition wall opening 1113 arranged near the lower portion of the liquid storage portion 101, the liquid storage portion 101 and the controlled release portion 102 are separated by the liquid storage element shell partition wall 111 and are connected through the partition wall opening 1113.

[0052] The liquid storage element housing 110 can be made of plastic or metal, or can be made of paper-plastic composite film, paper-aluminum-plastic composite film, etc. The outer contour of the liquid storage element housing 110 can be a circular, rectangular, elliptical or other geometric shape designed according to requirements.

[0053] The liquid storage element housing 110 may be provided with a liquid storage element through hole 130 of the liquid storage element 100 axially penetrating therein, and the central axis of the liquid storage element through hole 130 is preferably arranged to coincide with the central axis of the liquid storage element 100. In this embodiment, the liquid storage element through hole 130 is also used as an aerosol passage 1303, and the outlet at one end of the aerosol passage 1303 is used as an aerosol outlet 1301, and the outlet at the other end is used as a heating element connection port 1302 connected to the heating element 930.

[0054] A liquid storage element housing partition wall 111 is provided in the inner cavity of the liquid storage element housing 110 , and the liquid storage element housing partition wall 111 divides the inner cavity of the liquid storage element housing 110 into two cavities, one cavity being used as the liquid storage part 101 , and the other cavity being used as the cavity for accommodating the controlled release part 102 .

[0055] In this embodiment, the composite liquid storage element 100 may also have a liquid storage element housing bottom sealing portion 112 to seal the lower opening of the liquid storage element housing 110. The liquid storage element housing bottom sealing portion 112 may be made of materials such as silicone or plastic. A liquid injection hole (not shown) may be provided on the top 818 of the liquid storage element housing 110 or the liquid storage element housing bottom sealing portion 112, and the liquid injection hole may be closed after the liquid is injected. After the liquid is used up, the liquid injection hole may be reopened and liquid may be injected into the composite liquid storage element 100 again.

[0056] The bottom sealing portion 112 of the liquid storage element housing may also be provided with a sealing portion through hole 1122 penetrating the bottom sealing portion 112 of the liquid storage element housing, and the sealing portion through hole 1122 is in communication with the aerosol passage 1303, and is preferably coaxially arranged with the aerosol passage 1303. The end entrance of the sealing portion through hole 1122 away from the aerosol passage 1303 is provided as a sealing portion air inlet 1121, which is used to deliver air to the aerosol passage 1303.

[0057] In this embodiment, the composite liquid storage element 100 can also be provided with a sealing protrusion 1123 facing the liquid storage part 101 on the lower sealing part 112 of the liquid storage element shell. The setting of the sealing protrusion 1123 can reduce the residual air in the liquid storage part 101 when the liquid is injected, thereby reducing the risk of liquid leakage during storage and transportation.

[0058] In this embodiment, the range of the cavity of the controlled release portion 102 is the space enclosed by part of the top 818 of the liquid storage element shell 110, the liquid storage element shell partition wall 111, the wall of the aerosol channel 1303 and part of the bottom sealing portion 112 of the liquid storage element shell; the range of the liquid storage portion 101 is the space enclosed by part of the top 818 of the liquid storage element shell 110, the liquid storage element shell partition wall 111, the side wall of the liquid storage element shell 110 and part of the bottom sealing portion 112 of the liquid storage element shell.

[0059] In this embodiment, the liquid storage part 101 and the controlled release part 102 are separated by a liquid storage element housing partition wall 111 , and are connected near the lower part of the liquid storage part 101 through a partition wall opening 1113 .

[0060] In this embodiment, the composite liquid storage element 100 may further include a heating element 930, which is assembled in the heating element connection port 1302 and directly connected to the controlled release portion 102 of the composite liquid storage element 100. Alternatively, the heating element 930 may be indirectly connected to the controlled release portion 102 through a liquid guide element, or directly connected to the liquid storage portion 101, so as to supply liquid to the heating element 930.

[0061] In this embodiment, the heating element connection port 1302 of the aerosol channel 1303 is connected to 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 can be integrally formed with the liquid storage element housing 110, or it can be formed separately. The separately formed aerosol channel 1303 can be a plastic tube, a stainless steel tube or a glass fiber tube. When the aerosol channel 1303 is formed separately, it can be detachably mounted on the liquid storage element housing 110. Alternatively, an atomization chamber can be set at the bottom of the composite liquid storage element 100, and the heating element 930 is assembled in the atomization chamber, and the atomization chamber is connected to the heating element connection port 1302.

[0062] Through a specific design, the composite liquid storage element 100 can be provided with a through hole or a small groove on the wall of the upper part of the aerosol channel 1303, so that the air can flow between the aerosol channel 1303 and the upper part of the controlled release part 102 through the through hole or the small groove. A controlled release part vent hole 1021 can also be provided on the top 818 of the liquid storage element housing 110 at the top of the controlled release part 102, or a non-tightly fitted silicone plug can be used. Through these methods, the top or upper part of the controlled release part 102 can be connected to the outside atmosphere.

[0063] like Figure 1c and 1dAs shown, the controlled release part 102 can be a capillary medium, such as a capillary medium made by sponge or fiber bonding. The fiber can be filament or staple fiber, and the fiber fineness is 1-30 denier, preferably 1.5-10 denier; the fiber can be a single component fiber, such as polypropylene fiber, polyester fiber, polyamide fiber, etc.; it can also be a double component fiber 2 with a skin-core structure or a parallel structure, the skin layer 21 and the core layer 22 of the skin-core structure fiber can be a concentric structure or an eccentric structure, and the skin layer 21 of the double component fiber 2 with a skin-core structure can be polyethylene, polypropylene, polyester, copolyester, polyamide, polylactic acid, etc. The fibers can be bonded with a binder or a plasticizer to form a capillary medium, preferably the double component fiber 2 with a skin-core structure is made into a capillary medium by thermal bonding. The cross-sectional shape of the controlled release part 102 can be circular, semicircular, rectangular, square, elliptical or other geometric shapes.

[0064] like Figure 1b As shown, in this embodiment, the cross section of the controlled release portion 102 is preferably a circular ring. The cross section of the liquid storage element housing partition wall 111 should match the cross section outer contour of the controlled release portion 102. In this embodiment, the cross section of the liquid storage element housing partition wall 111 is as shown in FIG. Figure 1e shown.

[0065] The density of the controlled release portion 102 of this embodiment is 0.03-0.2 g / cm3, such as 0.03 g / cm3. 3 , 0.04 g / cm 3 , 0.05 g / cm 3 , 0.06 g / cm 3 , 0.08 g / cm 3 , 0.1 g / cm 3 , 0.12 g / cm 3 , 0.15 g / cm 3 , 0.18 g / cm 3 , 0.2 g / cm 3 , preferably 0.04-0.12 g / cm 3 When the density is less than 0.03 g / cm 3 When the density is greater than 0.2 g / cm, the strength of the controlled release portion 102 is insufficient and the manufacturing is difficult. 3 When the capillary force of the controlled-release part 102 is too high, it is difficult for external air to be introduced into the liquid storage part 101 through the controlled-release part 102, and the pressure fluctuation range in the liquid storage part 101 is large, which affects the stability of atomization, and the liquid residual rate after use is high. In this embodiment, the controlled-release part 102 made of a bicomponent fiber 2 with a skin-core structure by thermal bonding is preferably used.

[0066] The heating element 930 is usually a glass fiber bundle or cotton fiber bundle wrapped with a heating wire, a porous ceramic with a pre-embedded heating wire, a porous ceramic with a printed thick film heating element, or an ultrasonic atomizer, etc. The heating element 930 can be directly connected to the lower part of the controlled release part 102, or indirectly connected through a liquid guide element, or directly connected to the liquid storage part 101. The heating element 930 can include a wire 933 connected to an external power source and a wire pin 936.

[0067] The controlled release portion 102 can have a higher density near the heating element 930, for example, by using the glass fiber bundles at both ends of the heating element 930 to squeeze the inner side of the controlled release portion 102 and form a higher density locally, which is conducive to the enrichment of the liquid in the controlled release portion 102 near the heating element 930 and improves the stability of atomization.

[0068] Place the assembled composite liquid storage element 100 with the air inlet 1121 of the sealing part facing upwards, inject a proper amount of liquid from the injection hole reserved in the sealing part 112 at the lower part of the liquid storage element shell, and then close the injection hole. When injecting liquid, the air in the liquid storage part 101 should be discharged as much as possible, or liquid should be injected until part of the liquid is introduced into the controlled release part 102, but the liquid introduced into the controlled release part 102 should preferably not be greater than half of the liquid absorption capacity of the controlled release part 102. After injecting the liquid, place the composite liquid storage element 100 with the air inlet 1121 of the sealing part facing downwards, and the controlled release part 102 uses its capillary force to absorb part of the liquid from the liquid storage part 101 and generate negative pressure in the liquid storage part 101. When the controlled release part 102 absorbs liquid, the air in the controlled release part 102 is discharged from its upper part or top.

[0069] During use, the liquid on the heating element 930 is consumed by atomization and is replenished from the liquid storage element 100, so that the negative pressure in the liquid storage part 101 increases, and at the same time, the increased negative pressure pulls part of the liquid in the controlled release part 102 back to the liquid storage part 101. That is to say, the reduction of the liquid in the controlled release part 102 and the increase of the negative pressure in the liquid storage part 101 are carried out simultaneously, so that the liquid in the controlled release part 102 is gradually replaced by the outside air from top to bottom. When the air position in the controlled release part 102 drops to the partition wall opening 1113 of the partition wall 111 of the liquid storage element housing, the air is introduced into the liquid storage part 101, thereby reducing the negative pressure in the liquid storage part 101.

[0070] This process is repeated until the liquid in the liquid storage part 101 is used up. During the consumption of the liquid in the liquid storage part 101, the negative pressure in the liquid storage part 101 will fluctuate within a certain range but remain relatively stable, so that the atomization process remains relatively stable.

[0071] 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 to the heating element 930 is all from the controlled release part 102. As the liquid in the controlled release part 102 decreases, the amount of liquid and the amount of atomized aerosol supplied by the controlled release part 102 to the heating element 930 decreases until the user stops using it.

[0072] Depending on the type of liquid to be atomized and the requirements of use, the negative pressure in the liquid storage portion 101 can be changed by changing the capillary force of the controlled release portion 102 and the position of the partition wall opening 1113 of the liquid storage element shell partition wall 111, thereby changing the amount of liquid supplied to the heating element 930 and the amount of atomized aerosol.

[0073] like Figure 1f As shown, a partition wall groove 1111 extending from the bottom end to the top end of the liquid storage element shell partition wall 111 can be provided on the side where the liquid storage element shell partition wall 111 contacts the release control portion 102. The partition wall groove 1111 can also be provided as a partition wall convex rib to make it smoother for air to be introduced from the release control portion 102 into the liquid storage portion 101. Preferably, the partition wall groove 1111 or the partition wall convex rib is provided only on the side where the lower part of the liquid storage element shell partition wall 111 contacts the release control portion 102, so that the upper part of the release control portion 102 is tightly matched with the liquid storage element shell partition wall 111.

[0074] A gap is formed between the local position of the lower part and the partition wall 111 of the liquid storage element housing, so that the air can smoothly enter the liquid storage part 101 only when it drops to a certain height in the controlled release part 102, thereby preventing excessive or premature entry of air into the liquid storage part 101 and increasing the risk of liquid leakage. Preferably, the height of the partition wall groove 1111 or the partition wall rib does not exceed one third of the height of the partition wall 111 of the liquid storage element housing.

[0075] When the external environment undergoes a significant change, such as an increase in ambient temperature or a decrease in air pressure, the air in the liquid storage portion 101 expands, the negative pressure decreases, and part of the liquid in the liquid storage portion 101 is discharged and absorbed by the controlled release portion 102, thereby preventing leakage of the liquid in the liquid storage element 100. When the ambient temperature decreases, the air in the liquid storage portion 101 contracts, the negative pressure increases, and part of the liquid returns to the liquid storage portion 101 from the controlled release portion 102.

[0076] Second embodiment

[0077] Figure 2a This is a schematic diagram of the aerosol dispensing device of the second embodiment disclosed in the present invention. The structure of the composite liquid storage element 100 in this embodiment is similar to that of the first embodiment, and the same parts as those of the first embodiment will not be repeated in the description of this embodiment.

[0078] like Figure 2aAs shown, in this embodiment, the liquid storage element housing 110 is a cavity made of plastic, and the liquid storage element housing partition wall 111 is integrally formed with the liquid storage element housing 110. The controlled release portion 102 is made of a bicomponent fiber 2 of a skin-core structure, the bicomponent fiber 2 is a filament, the skin layer 21 is polyamide, and the density of the controlled release portion 102 is 0.1-0.2 g / cm 3 The heating element 930 is a glass fiber bundle wound with a heating wire, and the glass fiber bundles at both ends of the heating element 930 are connected to the lower end of the release control portion 102 .

[0079] The aerosol dispensing device 1 of this embodiment is provided with a mouth 898, and a condensate absorbing element 400 is provided in the mouth 898. The condensate absorbing element 400 and the controlled release part 102 are separated by a controlled release part assembly part 1022 such as silica gel. The aerosol passage 1303 for guiding the aerosol is a glass fiber tube, and the controlled release part assembly part 1022 is not tightly assembled with the aerosol passage 1303, so that air can flow between the controlled release part 102 and the aerosol passage 1303.

[0080] like Figure 2b As shown, the cross section of the release control portion 102 of this embodiment is a rectangle with a circular through hole, and this shape of the release control portion 102 is suitable for flat electronic cigarettes. The working principle of the aerosol dispensing device 1 of this embodiment is the same as that of the first embodiment.

[0081] In this embodiment, the aerosol dispensing device 1 further includes a main body housing 950, and a power supply 910 and a control circuit 920 installed in the main body housing 950. The liquid storage element housing 110 and the main body housing 950 can be integrally formed, or can be assembled after being separately formed.

[0082] Third embodiment

[0083] Figure 3a FIG. 1 is a schematic longitudinal section diagram of a composite liquid storage element according to a third embodiment of the present invention. Figure 3b 1 is a schematic cross-sectional view of the controlled release portion 102. The structure of this embodiment is similar to that of the first embodiment, and the same parts as those of the first embodiment will not be repeated in the description of this embodiment.

[0084] like Figure 3a As shown, in this embodiment, the length of the controlled release portion 102 is relatively short, which is beneficial to increase the volume of the liquid storage portion 101, and the density of the controlled release portion 102 is 0.03-0.08 g / cm 3 , which is made of polyamide fiber bonded by a plasticizer. The heating element 930 is a porous ceramic with a pre-embedded heating wire. Cotton cloth or linen cloth can be wrapped around the porous ceramic to reduce the risk of the controlled release part 102 being scalded by the porous ceramic.

[0085] The aerosol channel 1303 for guiding out the aerosol is made of a stainless steel tube, and a small hole or a small groove (not shown) is provided near the upper part of the controlled release part 102 in the stainless steel tube, so that air can flow between the upper part of the controlled release part 102 and the aerosol channel 1303. The working principle of the composite liquid storage element 100 of this embodiment is the same as that of the first embodiment.

[0086] In this embodiment, one or more magnetic suctions are installed at the bottom of the bottom sealing portion 112 of the liquid storage element housing of the composite liquid storage element 100 to facilitate the assembly between the composite liquid storage element 100 and the aerosol dispensing host.

[0087] like Figure 3b As shown, in this embodiment, the cross section of the release control portion 102 is rectangular in the middle, the two ends of the rectangle and the arc form a fan-shaped shape, and a through hole with a circular cross section is arranged in the middle.

[0088] Fourth embodiment

[0089] Figure 4a FIG. 4 is a schematic longitudinal section diagram of a composite liquid storage element according to a fourth embodiment of the present invention. Figure 4b This embodiment is similar in structure to the first embodiment, and the same parts as the first embodiment will not be described in detail in the description of this embodiment.

[0090] In this embodiment, the composite liquid storage element 100 is provided with an atomization chamber 934 encapsulated by the bottom sealing portion 112 of the liquid storage element housing, and the bottom sealing portion 112 of the liquid storage element housing can be made of silicone. The heating element 930 is a liquid-conducting core wrapped with a heating wire, and the liquid-conducting core can be a cotton fiber bundle or a glass fiber bundle, etc. The middle part of the liquid-conducting core is in the atomization chamber 934, and its two ends are encapsulated by the bottom sealing portion 112 of the liquid storage element housing outside the atomization chamber 934 and directly contact the liquid in the liquid storage portion 101.

[0091] This packaging method prevents the air in the atomization chamber 934 from entering the liquid storage portion 101 through the liquid-conducting core of the heating element 930 , while reducing the risk of liquid entering the atomization chamber 934 and leaking from the air inlet 1121 of the sealing portion.

[0092] In this embodiment, the density of the controlled release portion 102 is 0.05-0.12 g / cm 3 , which is made of a bicomponent fiber 2 with a core-sheath structure by thermal bonding, and the fiber sheath 21 is a copolyester of polyethylene terephthalate.

[0093] During use, the liquid on the heating element 930 is consumed by atomization, and the liquid is conducted from the liquid storage portion 101 through the two ends of the liquid-conducting core of the heating element 930 to the middle portion of the liquid-conducting core, thereby enabling the heating element 930 to obtain a continuous supply of liquid.

[0094] In this embodiment, a small hole is provided on the top shell of the controlled release part 102. During use, as the liquid is consumed, the negative pressure in the liquid storage part 101 rises, the liquid in the controlled release part 102 is released back to the liquid storage part 101, and the outside air is introduced into the liquid storage part 101 through the controlled release part 102, thereby maintaining the pressure in the liquid storage part 101 within a certain range. This process is continued until the liquid in the liquid storage part 101 is used up. After the liquid in the liquid storage part 101 is used up, the injection hole (not shown) of the lower sealing part 112 of the liquid storage element housing is opened, and the liquid can be injected before reuse.

[0095] like Figure 4b As shown, in this embodiment, the cross section of the release control portion 102 is a circular ring with a circular through hole.

[0096] Fifth embodiment

[0097] Figure 5a FIG. 4 is a schematic longitudinal section diagram of a composite liquid storage element according to a fifth embodiment of the present invention. Figure 5b is a schematic cross-sectional view of the controlled release portion, Figure 5c Schematic diagram of the cross section of the lower part of the partition wall of the liquid storage element housing. This embodiment is similar in structure to the first embodiment, and the same parts as the first embodiment will not be repeated in the description of this embodiment.

[0098] In this embodiment, the composite liquid storage element 100 is provided with an atomization chamber 934 encapsulated by the bottom sealing portion 112 of the liquid storage element housing, and the bottom sealing portion 112 of the liquid storage element housing can be made of silicone. The heating element 930 is a liquid-conducting core body wound with a heating wire, and the liquid-conducting core body can be a cotton fiber bundle or a glass fiber bundle, etc. The middle part of the liquid-conducting core body is in the atomization chamber 934, and its two ends are encapsulated outside the atomization chamber 934 by the bottom sealing portion 112 of the liquid storage element housing.

[0099] like Figure 5a As shown, the controlled release part 102 is disposed on both sides of the composite liquid storage element 100, and the lower part of the controlled release part 102 is connected to the two ends of the liquid guide core of the heating element 930. Figure 5b As shown, there are two controlled-release portions 102 , and the cross section of each controlled-release portion 102 is a fan-shaped plane formed by a line segment and a circular arc.

[0100] like Figure 5c As shown, a partition wall rib 1112 extending from the bottom end to the top end of the liquid storage element shell partition wall 111 can be provided on the side where the liquid storage element shell partition wall 111 contacts the release control portion 102. The partition wall rib 1112 can also be provided as a partition wall groove, so that air can be introduced from the release control portion 102 into the liquid storage portion 101 more smoothly. Preferably, the partition wall rib 1112 or the partition wall groove is provided only on the side where the lower part of the liquid storage element shell partition wall 111 contacts the release control portion 102, so that the upper part of the release control portion 102 is tightly matched with the liquid storage element shell partition wall 111.

[0101] In this embodiment, the density of the controlled release portion 102 is 0.05-0.15 g / cm 3 , which is made of a bicomponent fiber 2 with a core-sheath structure by thermal bonding, and the fiber sheath 21 is polyethylene or polypropylene.

[0102] When in use, the liquid on the heating element 930 is consumed by atomization, and the liquid is conducted from the controlled release portion 102 through the two ends of the liquid-conducting core of the heating element 930 to the middle part of the liquid-conducting core, so that the heating element 930 obtains a continuous supply of liquid.

[0103] In this embodiment, a small hole is provided in the top outer shell of the controlled release portion 102. During use, as the liquid in the controlled release portion 102 is consumed, the liquid is replenished from the liquid storage portion 101 into the controlled release portion 102, the negative pressure in the liquid storage portion 101 increases, and the liquid level in the controlled release portion 102 decreases until the outside air is introduced into the liquid storage portion 101 through the controlled release portion 102, thereby maintaining the pressure in the liquid storage portion 101 within a certain range.

[0104] This process continues until the liquid in the liquid storage part 101 is used up. When the device continues to be used, the liquid in the controlled release part 102 is gradually consumed until the user stops using the device. It is worth noting that in this embodiment, the lower part of the controlled release part 102 is squeezed by the atomization chamber 934 to form a density increasing part, so that the lower part of the controlled release part 102 produces a liquid enrichment effect, which is beneficial to improve the stability of liquid supply during use and reduce the liquid residue in the controlled release part 102 after use.

[0105] Sixth embodiment

[0106] Figure 6a FIG. 4 is a schematic longitudinal section diagram of a composite liquid storage element according to a sixth embodiment of the present invention. Figure 6b This embodiment is similar in structure to the first embodiment, and the same parts as the first embodiment will not be described in detail in the description of this embodiment.

[0107] In this embodiment, the composite liquid storage element 100 can be provided with an atomization chamber 934 encapsulated by the bottom sealing portion 112 of the liquid storage element housing, and the bottom sealing portion 112 of the liquid storage element housing can be made of silica gel. The heating element 930 is a porous ceramic printed thick film heating element, one side of the porous ceramic contacts the liquid in the liquid storage portion 101, and the liquid penetrates through the porous ceramic to the vicinity of the thick film heating element.

[0108] like Figure 6a As shown, the controlled release portion 102 is disposed on both sides of the composite liquid storage element 100. Figure 6b As shown, there are two controlled-release portions 102 , and the cross section of each controlled-release portion 102 is a fan-shaped plane formed by a line segment and a circular arc.

[0109] In this embodiment, the density of the controlled release portion 102 is 0.04-0.12 g / cm 3 , which is made of a bicomponent fiber 2 with a core-skin structure by thermal bonding, and the fiber skin 21 is polyethylene.

[0110] During use, the liquid on the heating element 930 is consumed by atomization, and the liquid in the liquid storage part 101 continuously penetrates to the vicinity of the thick film heating element, so that the heating element 930 obtains a continuous supply of liquid. In this embodiment, a small hole is provided on the top shell of the controlled release part 102. During use, as the liquid in the controlled release part 102 is consumed, the negative pressure in the liquid storage part 101 increases, and the liquid level in the controlled release part 102 decreases until the outside air is introduced into the liquid storage part 101 through the controlled release part 102, thereby maintaining the pressure in the liquid storage part 101 within a certain range. This process continues until the liquid in the liquid storage part 101 is used up.

[0111] Seventh embodiment

[0112] Figure 7a FIG. 1 is a schematic longitudinal section diagram of a composite liquid storage element according to a seventh embodiment of the present invention. Figure 7b This embodiment is similar in structure to the first embodiment, and the same parts as the first embodiment will not be described in detail in the description of this embodiment.

[0113] like Figure 7a As shown, in this embodiment, the length of the controlled release portion 102 is relatively short, which is beneficial to increase the volume of the liquid storage portion 101, and the density of the controlled release portion 102 is 0.05-0.1 g / cm 3 , is made of sponge, and the heating element 930 is a glass fiber bundle wrapped with electric heating wire.

[0114] The aerosol channel 1303 for guiding out the aerosol is made of a stainless steel tube. A small hole or a small groove (not shown) is provided on the stainless steel tube near the top of the controlled release part 102 so that air can flow between the top of the controlled release part 102 and the aerosol channel 1303 .

[0115] In this embodiment, a liquid conducting element 200 is disposed in the composite liquid storage element 100, and the glass fiber bundle of the heating element 930 is indirectly connected to the controlled release part 102 through the liquid conducting element 200. The liquid conducting element 200 has a higher capillary force than the controlled release part 102, and can enrich the liquid from the controlled release part 102.

[0116] The working principle of the aerosol dispensing device 1 of this embodiment is the same as that of the first embodiment, but due to the liquid enrichment effect of the liquid guiding element 200, the liquid in the controlled release portion 102 is released more fully, and less liquid remains after use.

[0117] In this embodiment, if Figure 7b As shown, the cross section of the controlled release portion 102 is an ellipse with a circular through hole in the middle.

[0118] Eighth embodiment

[0119] Figure 8a It is a schematic longitudinal section diagram of a composite liquid storage element 100 according to an eighth embodiment of the present invention; Figure 8b for Figure 8a The cross-sectional view of the middle controlled release portion. The structure of this embodiment is similar to that of the first embodiment, and the same parts as those of the first embodiment will not be repeated in the description of this embodiment.

[0120] like Figure 8a As shown, in this embodiment, the controlled release portion 102 includes a low-density portion 123, a high-density portion 124, and a density increasing portion 125 located between the low-density portion 123 and the high-density portion 124. The density of the low-density portion 123 is 0.03-0.1 g / cm 3 , the density of high density 124 is 0.06-0.2 g / cm 3 , wherein the low-density portion 123 and the density-increasing portion 125 are an integrated structure, and the high-density portion 124 is formed separately and is adjacent to the density-increasing portion 125 .

[0121] The heating element 930 is a glass fiber bundle wrapped with a heating wire, the aerosol channel 1303 for conducting the aerosol is made of a glass fiber tube, and the top of the control release part 102 is fixed by a non-tightly fitted control release part assembly part 1022 such as silicone, so that air can flow between the control release part 102 and the aerosol channel 1303.

[0122] Normally, the high-density portion 124 generates a high capillary force, and the high-density portion 124 has a high liquid content, which ensures the liquid supply to the heating element 930 and makes the atomization more stable and smooth. When an abnormal situation occurs, the controlled-release portion 102 absorbs liquid from the liquid storage portion 101. Since the density increasing portion 125 and the high-density portion 124 have a larger cross-sectional area, they have a larger liquid absorption capacity, which effectively improves the anti-leakage ability. When the liquid in the liquid storage portion 101 is consumed, continued use will consume the liquid in the controlled-release portion 102. Due to the enrichment effect of the high-density portion 124 on the liquid, the liquid in the controlled-release portion 102 is released more fully, and less liquid remains after use.

[0123] like Figure 8b As shown, in this embodiment, the cross section of the release control portion 102 is in the shape of a ring with a circular through hole in the middle.

[0124] In summary, the composite liquid storage element or aerosol dispersing device disclosed in the present invention can effectively control the liquid supply of the liquid storage element to the heating element, ensure stable and smooth atomization, and effectively prevent liquid leakage. The composite liquid storage element has a simple structure and can be used in various types of atomization devices, including disposable atomization devices, disposable composite liquid storage elements, and composite liquid storage elements for repeated injection. The above embodiments are only illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Any person skilled in the art may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical ideas disclosed in the present invention should still be covered by the claims of the present invention.
