Description

Technical Field

[0001] The present invention relates to an aerosol bomb with a gas-liquid channel, and particularly to an aerosol bomb with a gas-liquid channel in application fields such as liquid electric mosquito repellent, electric aromatherapy, electronic cigarette, and atomization of drug solutions. Background Art

[0002] Technologies for emitting liquids through ultrasonic atomization or electric heating are widely used in fields such as liquid mosquito repellent, aromatherapy, and electronic cigarettes. In liquid mosquito repellent and aromatherapy, the traditional method is to siphon the liquid to the top with a core rod and volatilize the liquid at the top of the core rod by gasification with a heater or ultrasonic atomization. For high-viscosity liquids such as essential oils, the speed at which the core rod siphons the liquid upward is usually difficult to keep up with the atomization speed of the liquid. Therefore, this technology requires a large amount of organic solvents to dilute the highly viscous active ingredients to increase the siphon speed of the liquid. The use of a large amount of organic solvents not only wastes resources but is also harmful to human health. If the highly viscous concentrated liquid can be directly emitted, not only can resource waste be reduced, but also the device can be miniaturized, making the aerosol bomb with a gas-liquid channel more beautiful and portable.

[0003] When using traditional tobacco, inhaling harmful substances such as tar generated when burning tobacco has a greater impact on health. Electronic atomized cigarettes use atomization to ingest nicotine or nicotine salts, and this method does not produce tar. A common technology in electronic atomized cigarettes is to heat an atomization core directly connected to the e-liquid, so that nicotine and the solvent are atomized together. This technology lacks precise control over the e-liquid derivation and is prone to e-liquid leakage, resulting in a poor consumption experience. Summary of the Invention

[0004] To solve the problems existing in the prior art, the present invention proposes an aerosol bomb with a gas-liquid channel. The aerosol bomb includes a liquid storage element, a heating element, and a gas-liquid channel. The liquid storage element and the heating element are connected by the gas-liquid channel. The gas-liquid channel includes at least one fluid cavity axially penetrating the gas-liquid channel, and the gas-liquid channel further includes a fluid core.

[0005] Further, the maximum inscribed circle diameter of the smallest cross-section in the fluid cavity is 0.05 mm to 1 mm.

[0006] Further, the gas-liquid channel is directly connected to the heating element.

[0007] Further, a buffer liquid storage is provided in the atomization chamber.

[0046] First embodiment

[0047] Figure 1a Schematic structural view of an aerosol bomb with a gas-liquid channel according to the first embodiment of the present invention; Figure 1b Cross-sectional schematic view of the gas-liquid channel in an aerosol bomb with a gas-liquid channel according to the first embodiment; Figure 1c Another cross-sectional schematic view of the gas-liquid channel in an aerosol bomb with a gas-liquid channel according to the first embodiment.

[0048] As Figure 1a 、 1b shown in 1c, the aerosol bomb with gas-liquid channels according to the first embodiment of the present invention, the aerosol bomb 800 includes a liquid storage element 100, a heating element and a gas-liquid channel 830. The liquid storage element 100 and the heating element are connected by the gas-liquid channel 830. The gas-liquid channel 830 includes at least one fluid chamber 831 axially penetrating the gas-liquid channel 830, and the gas-liquid channel 830 further includes a fluid core 832.

[0049] <Liquid storage element>

[0050] In the aerosol bomb 800 of the present invention, the liquid storage element 100 is a component for storing the liquid to be emitted. Different liquids can be stored therein according to the application purpose, such as essential oils for aromatherapy, or mosquito repellents for liquid mosquito coils, e-liquids for e-cigarettes, cannabidiol solutions, or liquid medicines for aerosols, etc. The cross-section of the liquid storage element 100 can be of various shapes, such as circular, elliptical, rectangular, etc., or a combination of various geometric shapes. The liquid in the liquid storage element 100 can be injected from the gas-liquid channel, or a top cover can be provided for the liquid storage element 100 and the top cover is closed after the liquid is injected.

[0051] The aerosol bomb 800 further includes an aerosol bomb housing 810. The aerosol bomb housing 810 has a bottom plate 815 and a top plate 818, and a top plate aerosol hole 819 is provided on the top plate 818. The liquid storage element 100 is disposed in the aerosol bomb housing 810.

[0052] The liquid storage element 100 may have a liquid storage element through hole 130 axially penetrating the liquid storage element 100. The liquid storage element through hole 130 can be used as the aerosol channel of the aerosol bomb 800.

[0053] The aerosol channel communicates the atomization chamber 934 and the top plate aerosol hole 819, and its function is to lead the aerosol in the atomization chamber 934 to the top plate aerosol hole 819. The aerosol channel can also be integrally formed with the liquid storage element 100, with the liquid storage element through hole 130 as the aerosol channel, or can be separately formed from plastics, metals, ceramics or glass and then assembled into the aerosol bomb 800.

[0054] The top plate aerosol hole 819 is a component for the vaporized or atomized liquid to be emitted to escape from the aerosol bomb 800. The top plate aerosol hole 819 can be made of plastics, ceramics or metals, etc. The top plate aerosol hole 819 communicates with the atomization chamber 934 through the aerosol channel. If the application of the aerosol bomb 800 is an e-cigarette, an oil-absorbing cotton can be installed at the aerosol channel or the top plate aerosol hole 819. The oil-absorbing cotton is a porous material that can absorb condensate. When the liquid in the e-cigarette is atomized, part of it will condense and form condensate when passing through the aerosol channel. The oil-absorbing cotton can absorb the condensate before the aerosol enters the user's mouth, thereby improving the smoking experience.

[0055] <Atomizing section>

[0056] The atomizing section of the present invention includes an atomizing chamber 934 and a heating element. The atomizing chamber 934 is a cavity where the liquid is vaporized or atomized. In this embodiment, the atomizing chamber 934 is disposed in the region between the bottom of the liquid storage element 100 and the bottom plate 815. A heating element is disposed in the atomizing chamber 934, and an air inlet hole can be provided as needed. For example, a through hole 816 is provided on the bottom plate 815 as the air inlet hole. The liquid is vaporized or atomized by the heating element in the atomizing chamber 934 and escapes from the aerosol cartridge 800 through the through hole 130 of the liquid storage element and the aerosol hole 819 of the top plate.

[0057] The heating element of the present invention generally refers to a component that can vaporize or atomize the liquid according to the usage requirements. The heating element includes a heating core 930, such as an electric wire wound around glass fiber or cotton, a porous ceramic embedded with an electric wire, a ceramic with a printed thick film heating element, etc. The heating element may further include a liquid guiding element 200, such as glass fiber or cotton wound with an electric wire, a non-woven fabric wrapped around a porous ceramic embedded with an electric wire, etc.

[0058] The heating element further includes a wire 933. The heating element is connected to a power source (not shown) through the wire 933.

[0059] An electrically heated heating element can be used: such as winding an electric wire around a bundle of glass fiber or cotton rope, or winding cotton or cotton non-woven fabric around an electric wire, or embedding an electric wire in a ceramic, or printing a thick film heating element on the surface of a ceramic, or using a positive temperature coefficient ceramic heating element; an ultrasonic heating element or other types of heating elements can also be used. According to the application requirements, the heating element can be made into various shapes suitable for assembly.

[0060] A support member 935 can be provided at the bottom of the atomizing chamber 934. The support member 935 can be made of a material such as silica gel to strengthen the contact and communication between the gas-liquid channel 830 and the heating element.

[0061] Due to abnormal conditions during the storage, transportation or use of the aerosol cartridge 800, the liquid leaks. The support member 935 can be designed to be made of a material with both buffering and liquid storage functions. At the same time, the atomizing chamber 934 can also be designed to have a structure capable of storing part of the liquid, which can accommodate the liquid derived from the liquid storage element 100, thereby preventing the liquid from leaking to the outside.

[0062] When needed, a buffer liquid storage (not shown) can be provided in the atomization chamber 934. The gas-liquid channel 830 and the heating element can be respectively connected to the buffer liquid storage. The buffer liquid storage can store a part of the liquid derived from the liquid storage element 100 and can also conduct the liquid between the gas-liquid channel 830 and the heating element. When an abnormal situation occurs during the storage, transportation or use of the aerosol cartridge 800, the buffer liquid storage can absorb the liquid derived from the liquid storage element 100, reducing the risk of liquid leakage to the outside. The support member 935 and the buffer liquid storage can be made of fibers. The fibers can be natural fibers such as cotton, modified products of natural fibers such as cellulose acetate fibers, or synthetic fibers such as polyester fibers, polylactic acid fibers, core-sheath structure polyethylene / polypropylene bicomponent fibers, etc. The fibers can be bonded to form the buffer liquid storage in a required shape, facilitating assembly into the aerosol cartridge 800. Additionally, the support member 935 and the buffer liquid storage can also be made of sponge, such as polyurethane sponge, polyvinyl alcohol sponge, etc. The buffer liquid storage can be provided with a high-density part and a low-density part, thereby better controlling the liquid derivation in the liquid storage element 100 and improving the liquid leakage prevention ability.

[0063] <Gas-liquid channel>

[0064] In this embodiment, the liquid storage element 100 and the heating element are connected by the gas-liquid channel 830. As Figure 1b and Figure 1c shown, the gas-liquid channel 830 includes at least one fluid cavity 831 axially penetrating the gas-liquid channel 830, and the gas-liquid channel 830 further includes a fluid core 832. The gas-liquid channel 830 is provided in the atomization chamber 934.

[0065] As Figure 1b shown, for a gas-liquid channel 830, the gas-liquid channel 830 includes a gas-liquid channel outer tube 834, a fluid core 832 provided inside the gas-liquid channel outer tube 834, gas-liquid channel reinforcing ribs 833 provided between the gas-liquid channel outer tube 834 and the fluid core 832, and fluid cavities 831 separated by the gas-liquid channel reinforcing ribs 833.

[0066] As Figure 1c shown, for another structure of the gas-liquid channel 830. The gas-liquid channel 830 includes a gas-liquid channel outer tube 834, a fluid core 832 provided inside the gas-liquid channel outer tube 834, and a fluid cavity 831. The gas-liquid channel outer tube 834 and the fluid core 832 are in tight fit. A plurality of grooves axially penetrating the gas-liquid channel 830 are formed on the outer peripheral portion of the fluid core 832, and the grooves and the gas-liquid channel outer tube 834 together form the fluid cavity 831.

[0067] The fluid channel 831 can be used as a gas channel or a liquid channel, and at least one of the fluid channels 831 in the fluid channel 831 is used as a gas channel. In the equilibrium state, the fluid core 832 absorbs sufficient liquid, and the liquid on the peripheral surface of the fluid core 832 seals the gas channel. When the liquid is derived from the liquid storage element 100, the vacuum degree in the liquid storage element 100 increases, and the liquid sealing the gas channel is absorbed by the fluid core 832, and the liquid seal of part or all of the fluid channels 831 disappears. The air in the atomization chamber 934 enters the liquid storage element 100 through the gas channel. When the vacuum degree in the liquid storage element 100 decreases to the equilibrium state, the gas channel is sealed again.

[0068] The maximum inscribed circle diameter of the minimum cross-section in the fluid channel 831 is 0.05 mm - 1 mm, and "mm" in this article all refers to millimeters. When the fluid channel 831 with a smaller inscribed circle diameter is used as the gas channel, its liquid sealing ability is stronger, which is suitable for applications with lower viscosity and smaller liquid output. When the fluid channel 831 with a larger inscribed circle diameter is used as the gas channel, its liquid sealing ability is weaker, which is suitable for applications with higher viscosity or larger liquid output. According to the properties of the liquid and application requirements, the maximum inscribed circle diameter of the minimum cross-section of the fluid channel 831 is 0.05 mm - 1 mm, such as 0.05 mm, 0.08 mm, 0.2 mm, 0.5 mm, 0.6 mm, 0.8 mm, 1 mm. In the equilibrium state, the gas channel is sealed by the liquid on the peripheral surface of the fluid core 832 due to capillary force.

[0069] The gas-liquid channel 830 can be directly connected to the heating element, or the heating element is indirectly connected to the gas-liquid channel through a buffer liquid storage, so that the liquid is conducted from the liquid storage element 100 to the heating element through the gas-liquid channel. Usually, the fluid core 832 is set as a liquid channel, and the fluid core 832 is made by fiber bonding. For example, polyester fibers are bonded into the fluid core 832 with an adhesive, or two-component fibers are thermally bonded into the fluid core 832, etc. In this embodiment, the fluid core 832 can participate in forming the gas channel.

[0070] When the liquid is atomized, the liquid is continuously replenished from the liquid storage element 100 to the heating element or its periphery through the gas-liquid channel 830. When the external control device commands the heating element to work, the liquid on the heating element is atomized, and the aerosol escapes from the aerosol cartridge 800 through the aerosol channel and the top plate aerosol holes 819. At the same time, the liquid in the liquid storage element 100 is derived through the liquid channel of the gas-liquid channel 830 and replenished to the heating element. As the liquid is derived, when the vacuum degree in the liquid storage element 100 rises to a certain level, the liquid seal of the gas channel in the gas-liquid channel 830 is opened, and the air in the atomization chamber 934 enters the liquid storage element 100 through the gas channel, causing the vacuum degree in the liquid storage element 100 to drop, and the gas channel is sealed again. This process is repeated continuously so that the atomization process can continue until the liquid in the liquid storage element 100 is used up.

[0071] Second Embodiment

[0072] Figure 2a FIG. is a schematic structural diagram of an aerosol bomb with a gas-liquid channel according to the second embodiment of the present invention; Figure 2b FIG. is a cross-sectional schematic diagram of the gas-liquid channel in the aerosol bomb with a gas-liquid channel according to the second embodiment; Figure 2c FIG. is a sectional schematic diagram of the gas-liquid channel in the aerosol bomb with a gas-liquid channel according to the second embodiment. The structure of this embodiment is similar to that of the first embodiment, and the same parts as those in the first embodiment will not be described in detail in the description of this embodiment.

[0073] In this embodiment, the cross-section and section of the gas-liquid channel 830 are respectively as shown in Figure 2b and Figure 2c shown. A short outer gas-liquid channel tube 834 is provided at the bottom of the liquid storage element 100, and the fluid core 832 is inserted into the outer gas-liquid channel tube 834. Three gas-liquid channel reinforcing ribs 833 are provided between the fluid core 832 and the outer gas-liquid channel tube 834. A fluid cavity 831 is formed between the inner wall of the outer gas-liquid channel tube 834, the gas-liquid channel reinforcing ribs 833 and the outer wall of the fluid core 832. The maximum inscribed circle diameter of the minimum cross-section of the fluid cavity 831 is 0.5 mm. The fluid cavity 831 can be used as a gas channel, and the liquid channel is the fluid core 832.

[0074] The heating element includes a heating core 930 and a liquid guiding element 200. The heating core 930 is an electric heating wire, and the liquid guiding element 200 is a fiberglass bundle or a cotton string, and the electric heating wire is partially wound around the fiberglass bundle or the cotton string. The liquid guiding element 200 is in direct contact with the gas-liquid channel 830 in the atomization chamber 934, so that the liquid can be directly conducted from the liquid storage element 100 through the gas-liquid channel 830 to the liquid guiding element 200 of the heating element.

[0075] In this embodiment, a support member 935 is further provided in the atomization chamber 934 for supporting the heating element. Both ends of the liquid guiding element 200 are bent and then supported by the support member 935.

[0076] The aerosol bomb 800 of this embodiment is suitable for applications such as electronic cigarettes. The liquid derivation and atomization principle are similar to those of the first embodiment and will not be described in detail here.

[0077] The support member 935 of this embodiment is made of silicone and is designed into a special shape. For example, the cross-sectional view of the support member 935 is two symmetrical "L" shapes, so that a "depression" is formed in the atomization chamber 934. When the aerosol bomb 800 encounters abnormal fluctuations in the external environment during storage, transportation and use, a small amount of liquid will be discharged from the liquid storage element 100 through the liquid channel and temporarily stored in the "depression" of the atomization chamber 934, reducing the risk of liquid leakage. When the liquid on the heating element is consumed, the liquid temporarily stored in the depression of the atomization chamber 934 will be consumed first, so that no liquid will remain in the atomization chamber 934.

[0078] The aerosol bomb 800 may include a condensate absorbing element 400. In this embodiment, Figure 2a As shown, a condensate absorption element 400 may be disposed between the top plate 818 and the liquid storage element 100 to absorb condensate in the aerosol, thereby further improving the user experience.

[0079] The aerosol bomb 800 of the present embodiment is arranged as a contact connection end at the end of the wire 933, so that the aerosol bomb 800 is connected to the control device in a contact manner when in use. To adapt to different liquid viscosities, surface tensions and different atomization speed requirements, the maximum inscribed circle diameter of the minimum cross section of the fluid cavity 831 can be set to be less than 0.5mm, such as 0.08mm or 0.25mm, or greater than 0.5mm, such as 0.8mm or 1mm. At the same time, the cross-sectional area and porosity of the fluid core 832 as the liquid channel can also be set to increase or decrease the liquid guiding speed. Of course, the atomization speed is also related to factors such as the size of the glass fiber bundle and the heating power.

[0080] Third embodiment

[0081] Figure 3a is a schematic structural diagram of an aerosol bomb with a gas-liquid channel according to a third embodiment of the present invention; Figure 3b 1 is a cross-sectional view of the gas-liquid channel in the aerosol bomb with the gas-liquid channel according to the third embodiment. 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.

[0082] like Figure 3a As shown, the heating element in this embodiment includes a heating core 930 and a liquid guide element 200. The heating core 930 is a positive temperature coefficient thermistor heating element (PTC heating element for short), and the liquid guide element 200 is made of glass fiber, cotton or polyester fiber. The gas-liquid channel 830 in this embodiment is similar to that in the second embodiment, and the cross section is as shown in FIG. Figure 3b shown.

[0083] If the liquid is a low-viscosity essence solution, the maximum inscribed circle diameter of the smallest cross-section of the fluid channel 831 is set to 0.05 mm; if the liquid is a relatively high-viscosity essential oil or mosquito repellent, etc., the maximum inscribed circle diameter of the smallest cross-section of the fluid channel 831 can be set to 0.1 mm, 0.2 mm, 0.5 mm, or even 1 mm, so that gas can smoothly enter the liquid storage element 100 when the liquid is discharged.

[0084] This embodiment is particularly suitable for portable aerosol bombs 800 such as mini diffusers and mini liquid mosquito coils. To simplify the structure, the upper end of the liquid storage element 100 can be used as the top plate. The heating core 930 can also be fixed in an external control device to reuse the heating core 930 and reduce the usage cost.

[0085] Fourth Embodiment

[0086] Figure 4a FIG. is a schematic structural diagram of an aerosol bomb with a gas-liquid channel according to the fourth embodiment of the present invention; Figure 4b FIG. is a cross-sectional view of the gas-liquid channel in the aerosol bomb with a gas-liquid channel according to the fourth embodiment; Figure 4c FIG. is a sectional view of the gas-liquid channel in the aerosol bomb with a gas-liquid channel according to the fourth embodiment. This embodiment has a similar structure to the first embodiment, and the same parts as the first embodiment will not be described again in the description of this embodiment.

[0087] As Figures 4a to 4c shown, a fluid core 832 with axial grooves on its outer peripheral wall is inserted into the bottom short tube of the liquid storage element 100 to form a gas-liquid channel 830, and the short tube forms an outer tube 834 of the gas-liquid channel. As Figure 4b and 4c shown, the channel formed by the groove of the fluid core 832 and the inner wall of the bottom short tube of the liquid storage element 100 constitutes a fluid channel 831. The fluid core 832 serving as the liquid channel is made of fiber bonding. The maximum inscribed circle diameter of the smallest cross-section of the fluid channel 831 is 0.2 mm. If the liquid viscosity is relatively high, the maximum inscribed circle diameter of the smallest cross-section of the fluid channel 831 can be appropriately increased.

[0088] In this embodiment, a buffer liquid storage 835 is arranged in the atomization chamber 934. The buffer liquid storage 835 is made of fiber or sponge. For example, it is made of polyurethane sponge or polyethylene / polypropylene bicomponent fiber with a skin-core structure bonded together. The gas-liquid channel 830 is communicated with the heating element through the buffer liquid storage 835. The additional benefit brought by the buffer liquid storage 835 is that the heating element can obtain the liquid more stably, improve the stability of atomization, and enhance the user experience. The buffer liquid storage 835 with part of the liquid-absorbing part saturated still has partial liquid-absorbing performance, so this aerosol bomb 800 has good anti-leakage performance.

[0089] When this embodiment is used in an electronic atomizer, its advantage lies in that the buffer liquid storage 835 has sufficient contact with the liquid guiding element 200. If atomization occurs rapidly within a short period (commonly known as "taking a hard puff"), the liquid in the buffer liquid storage 835 can quickly replenish the liquid guiding element 200, reducing the risk of the liquid guiding element 200 of the heating element being burned due to a temporary lack of liquid. In this embodiment, a condensate absorption element 400 is provided at the upper end of the aerosol passage to absorb the condensate in the aerosol, improving the user experience.

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.

[0092] As Figure 5a shown, a fluid core 832 having an axial groove on the outer peripheral wall is inserted into the short tube at the bottom of the liquid storage element 100 to form a gas-liquid passage 830, and the short tube forms the outer tube 834 of the gas-liquid passage. As Figure 5b and 5c shown. The fluid core 832 is a liquid passage, and the passage formed by the groove of the fluid core 832 and the inner wall of the outer tube 834 of the gas-liquid passage is a fluid chamber 831, and the fluid chamber 831 is used as a gas passage. The maximum inscribed circle diameter of the minimum cross-section of the fluid chamber 831 is 1 mm, which is suitable for atomization of high-viscosity liquids, such as atomization of cannabidiol. If the liquid viscosity is low, the diameter of the maximum inscribed circle of the minimum cross-section of the fluid chamber 831 can be appropriately reduced, such as 0.8 mm or 0.6 mm. In this embodiment, a support member 935 made of polyurethane sponge or cotton is provided at the bottom of the atomization chamber 934, and the support member 935 has the function of buffer liquid storage.

[0093] The sixth embodiment

[0094] Figure 6a FIG. is a schematic structural diagram of an aerosol cartridge with a gas-liquid passage according to the sixth embodiment of the present invention; Figure 6b FIG. is a cross-sectional schematic diagram of the gas-liquid passage in the aerosol cartridge with a gas-liquid passage according to the sixth embodiment; Figure 6c FIG. is a sectional schematic diagram of the gas-liquid passage in the aerosol cartridge with a gas-liquid passage according to the sixth embodiment. 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.

[0095] The buffer liquid storage 835 may include a high-density part 8351 of the buffer liquid storage and a low-density part 8352 of the buffer liquid storage. In this embodiment, as Figure 6a shown, in this embodiment, the buffer liquid storage 835 is provided, including a high-density part 8351 of the buffer liquid storage close to the heating element and a low-density part 8352 of the buffer liquid storage located on the outer periphery. A gap is provided between the high-density part 8351 of the buffer liquid storage and the bottom of the liquid storage element 100. A cylindrical short tube with gas-liquid channel reinforcing ribs 833 on the inner wall extends from the bottom of the liquid storage element 100, and this cylindrical short tube serves as the outer tube 834 of the gas-liquid channel. The fluid core 832 is inserted into the outer tube 834 of the gas-liquid channel to form the gas-liquid channel 830.

[0096] As Figure 6b and 6c shown, the fluid core 832 is a liquid channel, and a fluid cavity 831 is formed between the outer tube 834 of the gas-liquid channel, the gas-liquid channel reinforcing ribs 833, and the fluid core 832. The fluid cavity 831 serves as a gas channel. The end face of the outer tube 834 of the gas-liquid channel abuts against the high-density part 8351 of the buffer liquid storage, the fluid core 832 is inserted into the high-density part 8351 of the buffer liquid storage, and the maximum inscribed circle diameter of the minimum cross-section of the fluid cavity 831 is 0.8 mm.

[0097] The heating element in this embodiment includes a heating core 930 and does not have a liquid guiding element. The heating core 930 is a porous ceramic embedded with an electric heating wire. After the aerosol cartridge 800 is assembled, the liquid in the liquid storage element 100 is conducted to the high-density part 8351 of the buffer liquid storage through the liquid channel of the gas-liquid channel 830, and further conducted to the porous ceramic. External gas enters the liquid storage element 100 from the gas channel of the gas-liquid channel 830. After the high-density part 8351 of the buffer liquid storage absorbs the liquid, the capillary force gradually decreases until the liquid no longer flows out of the liquid storage element 100, and the system reaches equilibrium.

[0098] Increasing or decreasing the maximum inscribed circle diameter of the minimum cross-section of the fluid cavity 831 can increase or decrease the liquid content in the high-density part 8351 of the buffer liquid storage at system equilibrium. During use, the heating element heats, the liquid atomizes, and the aerosol is emitted to the top plate aerosol holes 819 through the aerosol channel. The heating element obtains the liquid from the high-density part 8351 of the buffer liquid storage. The liquid content in the high-density part 8351 of the buffer liquid storage decreases, the capillary force rises, and the liquid flows out of the liquid storage element 100 through the liquid channel to the high-density part 8351 of the buffer liquid storage again. This process is repeated until the liquid in the liquid storage element 100 is used up. If the aerosol cartridge 800 continues to be used, the liquid in the buffer liquid storage 835 will continue to be conducted to the porous ceramic and atomize, but the liquid volume will gradually decay until it cannot be used.

[0099] This embodiment has better anti-leakage performance. Because under normal circumstances, the low-density part 8352 of the buffer liquid storage does not absorb liquid. However, when excessive liquid is exported and exceeds the capacity of the high-density part 8351 of the buffer liquid storage, the low-density part 8352 of the buffer liquid storage can absorb the excess liquid.

[0100] The seventh embodiment

[0101] Figure 7a FIG. is a schematic structural diagram of an aerosol bomb with a gas-liquid channel according to the seventh embodiment of the present invention; Figure 7b FIG. is a cross-sectional schematic diagram of the gas-liquid channel of an aerosol bomb with a gas-liquid channel according to the seventh embodiment; Figure 7c FIG. is a schematic sectional view of the gas-liquid channel of an aerosol bomb with a gas-liquid channel according to the seventh embodiment. 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.

[0102] As Figure 7a shown, a buffer liquid storage 835 is provided in the atomization chamber 934 of this embodiment. The buffer liquid storage 835 includes a low-density part 8352 of the buffer liquid storage close to the liquid storage element 100 and a high-density part 8351 of the buffer liquid storage located below the low-density part 8352 of the buffer liquid storage. A cylindrical short tube with gas-liquid channel reinforcing ribs 833 on the inner wall extends from the bottom of the liquid storage element 100. This cylindrical short tube serves as the outer tube 834 of the gas-liquid channel, and the fluid core 832 is inserted into the outer tube 834 of the gas-liquid channel to form a gas-liquid channel 830.

[0103] As Figure 7b 、 7c shown, the fluid core 832 is a liquid channel, and a fluid cavity 831 is formed between the outer tube 834 of the gas-liquid channel, the gas-liquid channel reinforcing ribs 833, and the fluid core 832. The fluid cavity 831 serves as a gas channel. The maximum inscribed circle diameter of the minimum cross-section of the fluid cavity 831 is 0.2 mm. The heating element is a glass fiber bundle wound with a resistance wire, and both ends of the glass fiber bundle are clamped between the high-density part 8351 and the low-density part 8352 of the buffer liquid storage or embedded in the high-density part 8351 of the buffer liquid storage. After the aerosol bomb 800 is assembled, the liquid in the liquid storage element 100 is conducted to the liquid guiding element 200 of the heating element and the high-density part 8351 of the buffer liquid storage through the liquid channel of the gas-liquid channel 830. External gas enters the liquid storage element 100 from the gas channel. After the high-density part 8351 of the buffer liquid storage absorbs the liquid, the capillary force gradually decreases until the liquid no longer exports from the liquid storage element 100, the gas channel is liquid-sealed, and the system reaches equilibrium.

[0104] During use, the heating element heats up to atomize the liquid in the glass fiber bundle, which is then dispersed through the aerosol passage and the aerosol holes 819 in the top plate. During the atomization process, the liquid is replenished to the glass fiber bundle from the liquid storage element 100 through the liquid passage, and the gas in the atomization chamber 934 passes through the gas passage and enters the liquid storage element 100. This process is repeated continuously until the liquid in the liquid storage element 100 is used up. If the liquid in the liquid storage element 100 is a particularly viscous liquid such as glycerol, the maximum inscribed circle diameter of the minimum cross-section of the gas passage can be increased to 0.3 mm or 0.5 mm so that the liquid seal in the gas passage can be smoothly opened to enable smooth atomization. If the viscosity of the liquid in the liquid storage element 100 is relatively low, the maximum inscribed circle diameter of the minimum cross-section of the gas passage can be appropriately reduced, such as 0.1 mm, so that the gas passage obtains an appropriate liquid seal strength to prevent liquid leakage.

[0105] In this embodiment, a condensate absorption element 400 is provided between the aerosol holes 819 in the top plate and the liquid storage element 100 to absorb the condensate in the aerosol and improve the user experience.

The fluid core 832 is inserted into the outer gas-liquid channel tube 834 to form a gas-liquid channel 830.

[0109] As Figure 8b 、 8c shown, the fluid core 832 is a liquid channel, and a fluid chamber 831 is formed between the outer gas-liquid channel tube 834, the gas-liquid channel reinforcing ribs 833 and the fluid core 832. The fluid chamber 831 serves as a gas channel. The maximum inscribed circle diameter of the minimum cross-section of the fluid chamber 831 is 0.3 mm, and the maximum inscribed circle diameter of the minimum cross-section of the fluid chamber 831 can also be appropriately increased or decreased according to the viscosity of the liquid and the usage requirements to obtain an appropriate amount of aerosol.

[0110] The heating core 930 of the heating element is a ceramic of a printed thick film heating body, and no liquid guiding element is provided in the heating element. In this embodiment, the liquid in the liquid storage element 100 is directly conducted to the heating core 930 through the fluid core 832. When working, the heating element heats up, and the liquid at the contact part between the fluid core 832 and the heating element is atomized and dissipated. The liquid on the fluid core 832 is replenished from the liquid storage element 100, and its principle is similar to that of the first embodiment, which will not be elaborated here.

According to the liquid viscosity, the maximum inscribed circle diameter of the minimum cross-section of the fluid chamber 831 can be appropriately increased or decreased.

[0115] A second liquid channel 836 is also provided at the bottom of the liquid storage element 100. The second liquid channel 836 is a small groove, and its cross-section is as Figure 9d shown. The second liquid channel 836 communicates with a buffer liquid storage 835 provided in the atomization chamber 934.
