Description

Technical field

The present invention relates to a gas-liquid channel aerosol can, is a gas-liquid channel aerosol can, in particular, for applications in such fields as liquid mosquito-proof appliances, electronic flavors, electronic cigarettes, and drug sprays.

State of the art

The method of dispersing liquid by ultrasonic atomization or electric heating is widely used in fields such as liquid mosquito repellents, flavors and electronic cigarettes. In liquid mosquito repellents and fragrances, the traditional methods are to pour the liquid with a siphon and evaporate the liquid at the top of the siphon using a heater or ultrasonic atomization. For high-viscosity liquids such as essential oils, it is generally difficult for the siphon to pump the liquid up to keep up with the liquid spraying rate, so this method requires a large amount of organic solvent to dilute the high-viscosity liquid, active ingredients to improve the liquid siphoning speed. The use of large amounts of organic solvents is not only a waste of resources, but also harmful to human health. If the concentrated liquid with higher viscosity is directly dispensed, it can not only reduce the waste of resources, but also miniaturize the device, making the gas-liquid channel aerosol can be more beautiful and easy to carry.

When using traditional tobacco, inhaling harmful substances, such as the tar formed when tobacco is burned, has a strong impact on health. E-cigarettes use vaping to ingest nicotine or nicotine salts, a method that does not produce tar. The conventional technology of electronic cigarettes is to heat the atomizer core, which is directly connected to the tobacco tar for electronic cigarettes, to atomize nicotine and solvent together. This technology is prone to leakage of tobacco tar due to the lack of precise control over the release of tobacco tar, as well as poor consumption experience.

The aerosol opening in the top plate 819 is connected to the spray chamber 934 through an aerosol channel. If the aerosol can 800 is used as an electronic cigarette, then in place of the aerosol channel or the aerosol hole on the top plate 819, a resin absorbent wadding, which is a condensate-absorbing material, can be installed. After the liquid is sprayed in an electronic cigarette, it partially condenses and forms condensate when passing through the aerosol channel of the resin, the absorbent cotton can absorb the condensate before the aerosol enters the user's mouth, thereby improving the smoking experience.

Spray part

The atomization portion described in the present invention includes a atomization chamber 934, which is a cavity in which liquid is gasified or atomized, and a heating element. The atomizing chamber 934 is provided with a heating element, and may be provided with an air collection hole if necessary, for example, a through hole of the bottom plate 816 is provided on the bottom plate 815 as an air collection hole. The liquid is gasified or atomized in the spray chamber 934 by the action of the heating element and exits into the aerosol can 800 through the through hole 130 of the liquid storage tank element 819 of the top plate.

The heating element described in the present invention generally refers to elements capable of gasifying or atomizing a liquid in accordance with the requirements of the operation.

When an unexpected situation occurs during storage, transportation, or use of the aerosol can 800, the buffer liquid storage tank can absorb the liquid discharged from the liquid storage member 100 and reduce the risk of liquid leakage to the outside. The support portion 935 and the buffer liquid storage tank may be made of fibers, and the fibers may be natural fibers such as cotton, modified natural fiber products such as cellulose acetate fibers, or synthetic fibers such as polyester fibers, polylactic acid, skin fibers. bicomponent polyethylene/polypropylene fiber with a core, etc. The fibers can be combined into a buffer liquid storage tank of a desired shape to facilitate assembly of the aerosol can 800. In addition, the support portion 935 and the buffer liquid storage tank can also be made of a sponge such as polyurethane sponge, polyvinyl sponge, etc. The buffer liquid storage tank can be installed in both the high density part and the low density part, which can better control the output of the liquid storage member 100 and improve the ability to prevent liquid leakage.

Gas-liquid channel

In this embodiment, the liquid storage element 100 and the heating element are connected by a gas-liquid passage 830. As shown in FIG. 1b and 1c, the gas-liquid passage 830 includes at least one liquid passage 831 extending axially through the gas-liquid passage 830, and the gas-liquid passage 830 further includes a liquid core 832. The gas-liquid passage 830 is provided in the spray chamber 934.

As shown in FIG. 1b. gas-liquid channel 830, gas-liquid channel 830 includes an outer gas-liquid channel pipe 834, a liquid core 832 installed in the outer pipe 834 of the gas-liquid channel, a gas-liquid channel amplifier 833 installed between the outer pipe 834 and the liquid core 832, and a fluid channel 831 separated from the amplifier 833 gas-liquid channel.

Gas-liquid channel 830 of another design, shown in Fig 1c. The gas-liquid passage 830 includes a gas-liquid passage outer tube 834, a liquid core 832 installed in the gas-liquid passage outer tube 834, and a liquid passage 831. The gas-liquid passage outer tube 834 closely coordinates with the liquid core 832, and multiple axial directions are formed on the periphery of the liquid core 832, passing through the gas-liquid channel 830, together with the outer pipe 834 of the gas-liquid channel, a liquid channel 831 is formed.

The liquid passage 831 may be used as a gas passage or a liquid passage, and at least one liquid passage 831 in the liquid passage 831 may be used as a gas passage. In the equilibrium state, the liquid core 832 absorbs a sufficient amount of liquid, and the liquid on the surface of the liquid core 832 plugs the gas channel. When the liquid leaves the liquid storage element 100, the degree of vacuum in the liquid storage element 100 increases, the liquid in the liquid-sealed gas channel is absorbed by the liquid core 832, the liquid channel 831 partially or completely disappears, the air from the spray chamber 934 enters through the gas channel into the element liquid storage 100, when the degree of vacuum in the liquid storage element 100 is reduced to an equilibrium state, the gas passage is closed again by the liquid passage.

The maximum inner cut circle diameter of the smallest cross-section of the liquid passage 831 is 0.05 mm-1 mm, in this case "mm" means millimeter. When the liquid passage 831 with a smaller inscribed circle diameter is used as a gas passage, the sealing capability of the liquid is higher and it is suitable for applications with low viscosity and low liquid output. When the liquid passage 831 with a large inscribed circle diameter is used as a gas passage, the sealing ability of the liquid is poor, and it is suitable for applications with high viscosity or large liquid output. Depending on the fluid properties and application requirements, the maximum inscribed circle diameter of the smallest cross-section of fluid channel 831 should be 0.05mm-1mm, e.g. 0.05mm, 0.08mm, 0.2mm, 0.5mm, 0.6mm, 0.8mm, 1mm. In the equilibrium state, the gas channel is sealed with liquid on the peripheral surface of the liquid core 832 due to the capillary force.

The gas-liquid passage 830 may be directly connected to the heating element, or the heating element may be indirectly connected to the gas-liquid passage through the buffer liquid storage tank, so that liquid passes from the liquid storage element 100 to the heating element through the gas-liquid passage. Fluid core 832 is typically a fluid channel, and fluid core 832 is made of a fibrous compound such as polyester fibers bonded to fluid core 832 with a binder, or bicomponent fibers thermally bonded to fluid core 832, etc. In this embodiment, the liquid core 832 may participate in the composition of the gas channel.

When spraying, the liquid is continuously added through the gas-liquid channel 830 from the liquid storage element 100 to the heating element or its perimeter. When the external control device instructs the heating element to operate, the liquid on the heating element is sprayed and exits the aerosol can 800 through the aerosol channel and the aerosol hole 819 in the top plate, and the liquid storage element 100 passes through the gas-liquid channel 830. The liquid channel is output and supplemented with a heating element. As the liquid is discharged, when the vacuum degree of the liquid storage element 100 rises to a certain level, the liquid seal of the gas passage of the gas-liquid passage 830 opens, and the air in the spray chamber 934 enters the liquid storage element 100 through the gas passage, the vacuum degree of the liquid storage element 100 decreases, and the gas channel becomes liquid. This process is repeated, continuously spraying, until the liquid in the liquid storage element 100 is used up.

The fluid channel 831 is formed between the inner wall of the outer pipe 834 of the gas-liquid channel, the amplifier 833 of the gas-liquid channel, and the outer wall of the liquid core 832. The maximum inscribed circle diameter of the smallest cross section of the fluid channel 831 is 0.5 mm, the fluid channel 831 can be used as a gas channel, the liquid channel is liquid core 832.

When the aerosol can 800 collides with abnormal fluctuations in the external environment during storage, transportation and use, a small amount of liquid will be ejected from the liquid storage element 100 through the liquid passage and temporarily stored in the "trough" of the spray chamber 934, which reduces the risk of liquid leakage. When the liquid is consumed by the heating element, the liquid temporarily stored in the cavity of the spray chamber 934 is preferred, so that no liquid remains in the spray chamber 934.

The aerosol can 800 may include a condensation absorbing element 400. In this embodiment, as shown in FIG. 2a, the condensation absorbing member 400 may be positioned between the top plate 818 and the liquid storage member 100, which may absorb the condensation in the aerosol and further enhance the user experience.

The aerosol can 800 in this embodiment is provided with a contact-type connecting end at the end of the wire 933 so that the aerosol can 800 can be contacted with the control device in use. Considering the different requirements for fluid viscosity, surface tension and spray rate, the maximum diameter of the inner cut circle of the minimum cross section of the fluid passage 831 can be set to less than 0.5 mm, such as 0.08 mm or 0.25 mm, or more than 0 .5 mm, such as 0.8 mm or 1 mm. At the same time, factors such as the cross-sectional area and porosity of the fluid core 832 serving as the fluid channel can be set to increase or decrease the speed of the guiding fluid.

After the aerosol can 800 is assembled, the liquid in the liquid storage member 100 is directed through the liquid passage of the gas-liquid passage 830 to a portion of the high-density buffer liquid storage tank 8351 and further into the porous ceramic. External gas enters the liquid storage element 100 from the gas passage 830, after the liquid is absorbed by a part of the high density buffer liquid storage tank 8351, the capillary force gradually decreases until the liquid leaves the liquid storage element 100 and the system reaches equilibrium.

Increasing or decreasing the maximum inscribed circle diameter of the smallest cross section of the fluid passage 831 can increase or decrease the liquid content of the high density buffer liquid storage tank portion 8351 when the system is in equilibrium. In use, the heating element is heated, the liquid is atomized, and the aerosol is ejected into the aerosol opening 819 of the top plate through the aerosol channel. The heating element receives liquid from the high-density buffer liquid storage tank part 8351, the liquid content in the high-density buffer liquid storage tank part 8351 decreases, the capillary force increases, and the liquid again exits the liquid storage element 100 into the high-density buffer liquid storage tank part. density 8351 through the liquid channel. This process is repeated until the liquid in the liquid storage element 100 is used up. If the aerosol can 800 continues to be used, the liquid in the buffer liquid storage tank 835 will still be directed towards the porous ceramic and sprayed, but the amount of liquid will gradually decrease until it can no longer be used.

This embodiment has better sealing properties. Because normally the low density buffer liquid storage tank part 8352 does not normally absorb liquid, the excess liquid is discharged and exceeds the capacity of the high density buffer liquid storage tank part 8351, the low density buffer liquid storage tank part 8352 can absorb excess liquid.
