Description

Technical Field

[0001] The invention relates to an aerosol bomb, in particular to an aerosol dispersing device with a liquid guide element for gasifying or atomizing liquid, such as an electronic cigarette, an electric mosquito coil, an electric aromatherapy device and a drug atomization inhalation device. Background Art

[0002] Aerosol dispensing devices are widely used in various fields of daily life, such as electronic cigarettes, electric mosquito coils, electric aromatherapy, and drug atomization inhalation devices. A common structure is to install an atomization core in the aerosol dispensing device, such as a porous ceramic with a pre-embedded heating wire. When the airflow passes through the atomization device, the atomization core is heated, and the liquid is atomized and carried out by the airflow. In order to transfer the liquid in the liquid storage part to the atomization core more smoothly and prevent liquid leakage, a non-woven fabric is usually coated on the surface of the atomization core and fixed in the aerosol dispensing device. Because the non-woven fabric is soft, lacks strength, and is easy to wrinkle, it is difficult to make an aerosol dispensing device with stable quality. In the case of severe wrinkles, liquid leakage is likely to occur. The method of coating the surface of the atomization core with non-woven fabric requires a lot of manpower, is difficult to automate, has high cost, and low efficiency. Similar problems also exist in aerosol dispensing devices that vaporize or atomize liquids, such as electric mosquito coils, electric aromatherapy, and drug atomization inhalation devices. Summary of the invention

[0003] In order to solve the problems existing in the prior art, the present invention proposes an aerosol bomb, comprising an aerosol bomb shell; an aerosol channel arranged inside the aerosol bomb shell; a shell bottom sealing portion sealing the bottom of the aerosol bomb shell; a liquid storage element formed between the aerosol bomb shell, the wall of the aerosol channel and the shell bottom sealing portion; a liquid guide hole formed between the wall of the aerosol channel and the shell bottom sealing portion; a liquid guide element arranged in the liquid storage element and completely covering the liquid guide hole; and a heating element accommodated in the liquid guide hole and abutting against the liquid guide element.

[0004] Furthermore, a gap is provided between the heating element and the sealing portion of the bottom of the shell.

[0005] Further, the gap is filled with silicone spacer.

[0006] Furthermore, the liquid-conducting element is formed into a three-dimensional network structure by thermal bonding of the bicomponent fibers, wherein the bicomponent fibers have a skin layer and a core layer.

[0007] Furthermore, the liquid-conducting element is in sheet or tube shape.

[0008] Furthermore, the radial rigidity of the liquid-conducting element is greater than its axial rigidity.

[0009] Furthermore, the speed at which the liquid in the liquid-conducting element penetrates in the radial direction is greater than the speed at which the liquid penetrates in the axial direction.

[0010] Furthermore, a bottom plate is provided at the bottom of the aerosol bomb housing, and a buffer chamber is provided between the bottom plate and the sealing portion at the bottom of the housing.

[0011] Furthermore, oil-absorbing cotton is arranged in the buffer chamber.

[0012] Furthermore, the inner diameter of the portion of the aerosol passage close to the aerosol outlet is smaller than the inner diameter of the portion close to the heating element.

[0013] Furthermore, the thickness of the liquid-conducting element is 0.3 mm-3 mm.

[0014] Furthermore, the density of the liquid conducting element is 0.05 g / cm 3 -0.35 g / cm 3 .

[0015] Furthermore, the sheath and core of the bicomponent fiber are of a concentric structure or an eccentric structure.

[0016] Furthermore, the core layer of the bicomponent fiber has a melting point that is more than 20° C. higher than that of the sheath layer.

[0017] Furthermore, the sheath of the bicomponent fiber is polyolefin, copolyester of polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate or polylactic acid.

[0018] Furthermore, the core layer of the bicomponent fiber is polylactic acid.

[0019] The aerosol bomb of the present invention has a simpler structure, is easier to assemble, is conducive to automated assembly, and has lower costs. The aerosol bomb of the present invention can be used in both disposable electronic cigarettes and cigarette bombs, and is very suitable for large-capacity electronic cigarettes.

[0020] The liquid-conducting element made of two-component fiber bonding has high strength and toughness, is not easy to wrinkle or break during installation, can be easily assembled in the aerosol dispensing device, and is easy to realize assembly automation, improve efficiency, save costs, and is particularly suitable for manufacturing large-scale consumer products such as electronic cigarettes. Due to the three-dimensional structure of the three-dimensional network formed by the bonding of the two-component fibers, a large number of interconnected capillaries are formed in the liquid-conducting element. Such capillaries are conducive to the rapid and smooth conduction of liquid therein, improving the stability of replenishing liquid for the atomization core, thereby improving the atomization stability. By selecting the fiber fineness and setting the density of the liquid-conducting element, the size of the capillaries and the capillary force can be controlled, so that the liquid-conducting element is suitable for the requirements of different aerosol dispensing devices.

[0035] First embodiment

[0036] Figure 1a A longitudinal cross-sectional view of the aerosol bomb of the first embodiment disclosed in the present invention; Figure 1b A cross-sectional view of a liquid-conducting element according to a first embodiment of the present invention; Figure 1c yes Figure 1a and 1b An enlarged schematic diagram of a cross section of a bicomponent fiber; Figure 1d yes Figure 1a and 1b Another enlarged schematic cross-section of the bicomponent fiber in FIG.

[0037] like Figures 1a to 1d As shown, the aerosol bomb 800 according to the first embodiment of the present invention includes an aerosol bomb shell 810; an aerosol channel 1303 arranged inside the aerosol bomb shell 810; a shell bottom sealing portion 112 sealing the bottom of the aerosol bomb shell 810; a liquid storage element 100 formed between the aerosol bomb shell 810, the wall of the aerosol channel 1303 and the shell bottom sealing portion 112; a liquid guide hole 837 formed between the wall of the aerosol channel 1303 and the shell bottom sealing portion 112; a liquid guide element 200 arranged in the liquid storage element 100 and completely covering the liquid guide hole 837; and a heating element 931 accommodated in the liquid guide hole 837 and against the liquid guide element 200.

[0038] One side of the liquid-conducting element 200 contacts the liquid in the liquid storage element 100 , and the other side contacts the heating element 931 , so that the liquid-conducting element 200 conducts the liquid to the heating element 931 .

[0039] like Figures 1a to 1d As shown, according to the first embodiment of the present invention, the liquid-conducting element 200 is formed by thermally bonding bicomponent fibers 2 to form a three-dimensional network structure, and the bicomponent fibers 2 have a skin layer 21 and a core layer 22 .

[0040] <Shape, thickness, rigidity and liquid penetration rate of liquid-conducting elements>

[0041] The liquid-conducting element 200 may have a liquid-conducting element through hole 230 axially penetrating the liquid-conducting element 200 .

[0042] The liquid-conducting element 200 of this embodiment can be designed to be sheet-shaped or tubular according to the design of the aerosol bomb 800. Figure 1a and Figure 1b As shown, the liquid-conducting element 200 in this embodiment is configured to be tubular.

[0043] The liquid-conducting element 200 may also be designed in a sheet shape. The sheet-shaped liquid-conducting element 200 may also be provided with a liquid-conducting element through hole 230 .

[0044] According to the structure of the aerosol bomb 800, the cross section of the liquid-conducting element 200 can be made into a circular ring, an elliptical ring or other required shapes.

[0045] For the sheet-like liquid-conducting element 200, the axial direction is defined as the thickness direction, and the radial direction is defined as the direction perpendicular to the thickness. By adopting appropriate manufacturing technology, the fibers in the liquid-conducting element 200 can have more axial arrangement orientations. In this case, the axial rigidity of the sheet-like liquid-conducting element 200 is greater than its radial rigidity, and the speed of liquid penetration in the axial direction of the liquid-conducting element 200 is greater than the speed of liquid penetration in the radial direction; the fibers in the liquid-conducting element 200 can also have more radial arrangement orientations. In this case, the radial rigidity of the sheet-like liquid-conducting element 200 is greater than its axial rigidity, and the speed of liquid penetration in the radial direction of the liquid-conducting element 200 is greater than the speed of liquid penetration in the axial direction.

[0046] For the tubular liquid-conducting element 200, the axial direction is defined herein as the direction of the central axis of the liquid-conducting element through hole 230, and the radial direction is defined as the direction perpendicular to the central axis of the liquid-conducting element through hole 230. The fibers in the tubular liquid-conducting element 200 have more axial arrangement orientations, the axial rigidity of the liquid-conducting element 200 is greater than its radial rigidity, and the liquid in the liquid-conducting element 200 penetrates at a speed in the axial direction greater than the liquid in the radial direction.

[0047] The rigidity comparison method in this article is: place the liquid-conducting element 200 axially or radially, clamp it between two parallel plates, and measure the axial height or radial height of the liquid-conducting element 200 before compression; under the same force, measure the axial height or radial height of the liquid-conducting element 200 after the two plates axially or radially compress it, and calculate the compression deformation, which is the difference between the axial height or radial height before compression and the axial height or radial height after compression; divide the compression deformation by the axial height or radial height of the liquid-conducting element 200 before compression to obtain the compression ratio. The smaller the compression ratio, the greater the rigidity, and the larger the compression ratio, the smaller the rigidity.

[0048] The thickness of the liquid-conducting element 200 refers to the shortest distance for liquid to be conducted from one side of the liquid-conducting element 200 to the other side. The thickness of the tubular liquid-conducting element 200 is the thickness of the tube wall, and the thickness of the sheet-like liquid-conducting element 200 is the thickness in the thickness direction.

[0049] The thickness of the liquid-conducting element 200 is 0.3 mm to 3 mm, preferably 0.6 mm, 0.9 mm, 1.2 mm, 1.5 mm, and 2 mm. When the thickness of the liquid-conducting element 200 is less than 0.3 mm, it is difficult to make a uniform liquid-conducting element 200, and it is also inconvenient to install. When the thickness of the liquid-conducting element 200 is greater than 3 mm, the liquid-conducting element 200 occupies too much space in the aerosol bomb 800, especially for a tubular liquid-conducting element 200, when the thickness is greater than 3 mm, it is usually difficult to install in a small aerosol bomb 800. In addition, when the thickness is greater than 3 mm, the liquid-conducting element 200 absorbs too much liquid, affecting the utilization efficiency of the liquid.

[0050] In this embodiment, the fibers in the tubular liquid-conducting element 200 have more axial arrangement orientations, the axial rigidity is greater than the radial rigidity, and the fibers have better elasticity in the radial direction, which is beneficial for applying axial force when installing the liquid-conducting element 200.

[0051] <Density of liquid-conducting element>

[0052] The density of the liquid-conducting element 200 of this embodiment is 0.05-0.35 g / cm 3 , preferably 0.1-0.3 g / cm 3 When the density is less than 0.05 g / cm 3 When the density is greater than 0.35 g / cm, the liquid-conducting element 200 is not strong enough, and the tubular liquid-conducting element 200 is easily deformed or even wrinkled when assembled with the aerosol bomb 800, which affects the stability of atomization and even causes leakage in severe cases. 3 When the liquid is guided, the liquid guiding speed is slow, which affects the atomization efficiency. In addition, the hardness of the high-density liquid guiding element is too high, and the radial elasticity is insufficient, so the compatibility between the tubular liquid guiding element and the aerosol bomb 800 decreases.

[0053] <Bicomponent Fiber>

[0054] Figure 1c yes Figure 1a and 1b An enlarged cross-sectional diagram of a bicomponent fiber in FIG. Figure 1c As shown, the skin layer 21 and the core layer 22 are concentric structures. Figure 1d yes Figure 1a and 1b Another enlarged cross-sectional schematic diagram of the bicomponent fiber in FIG. Figure 1d As shown, the skin layer 21 and the core layer 22 are of eccentric structure. The liquid-conducting element 200 made of the bicomponent fiber 2 of concentric structure has greater rigidity, and the liquid-conducting element 200 made of the bicomponent fiber 2 of eccentric structure has better elasticity.

[0055] The bicomponent fiber 2 is a filament or a staple fiber. The liquid conducting element 200 made of filament has greater rigidity, and the liquid conducting element 200 made of staple fiber has better elasticity. The bicomponent fiber can be selected to make a suitable liquid conducting element 200 according to the performance requirements of the liquid conducting element 200.

[0056] The core layer 22 of the bicomponent fiber 2 has a melting point 20°C higher than the skin layer 21. The liquid-conducting element 200 of this embodiment is made by thermally bonding the bicomponent fibers 2 with a skin-core structure. The core layer 22 of the bicomponent fiber 2 has a melting point 20°C higher than the skin layer 21, which can keep the core layer 22 rigid when the fibers are thermally bonded, making it easy to manufacture a liquid-conducting element 200 with uniform gaps.

[0057] The cortex 21 of the bicomponent fiber 2 can be a polyolefin such as polyethylene and polypropylene. Polyolefin is a polymer of olefin, usually a general term for a class of thermoplastic resins obtained by polymerizing or copolymerizing α-olefins such as ethylene, propylene, 1-butene, 1-pentene, and 1-hexene. It can also be a common polymer such as polyester or low-melting point copolyester. When the cortex 21 is polyethylene, the core layer 22 can be a polymer such as polypropylene and polyethylene terephthalate (PET for short). When the cortex 21 is polypropylene, the core layer 22 can be PET, polyamide, etc. The cortex 21 of the bicomponent fiber 2 has a low melting point, which is beneficial to improve production efficiency and reduce manufacturing costs. The cortex 21 of the bicomponent fiber 2 has a high melting point, and the liquid-conducting element has a high temperature resistance, which is beneficial to increase the working temperature of the atomization core.

[0058] When the skin layer 21 is polylactic acid, according to the melting point of polylactic acid, for example, poly D, L-lactic acid with a melting point of 125-135°C is used as the skin layer 21, and the core layer 22 can be polypropylene, polyethylene terephthalate, poly L-lactic acid or poly D-lactic acid with a melting point of 155-180°C, etc. When the skin layer 21 is poly D-lactic acid or poly L-lactic acid with a melting point of 145-180°C, the core layer 22 can be polyethylene terephthalate, polybutylene terephthalate (PBT for short), polypropylene terephthalate (PTT for short), polyamide, etc. Polylactic acid is a biodegradable material, which can reduce the environmental pollution caused by the abandonment of the liquid-conducting element.

[0059] When the skin layer 21 is polyester or copolyester, a suitable core layer 22 can be selected according to the melting point of the skin layer 21. For example, the skin layer 21 uses PBT or PTT with a melting point of 225-235°C, and the core layer 22 can use PET with a melting point of 255-265°C. For another example, when the skin layer is a copolyester of polyethylene terephthalate (Co-PET) with a melting point of 110-120°C or 160-200°C, the core layer can use PET, PBT or PTT.

[0060] The fineness of the bicomponent fiber 2 used to make the liquid-conducting element 200 of the present invention is between 1-30 deniers, preferably 1.5-10 deniers. The bicomponent fiber 2 with a skin-core structure of less than 1 denier is difficult to manufacture and has high cost. The liquid-conducting element 200 made of fibers higher than 30 deniers has insufficient capillary force and poor liquid conduction. The bicomponent fiber 2 with a skin-core structure of between 1-30 deniers is easy to make the liquid-conducting element 200, and the bicomponent fiber 2 with a skin-core structure of 1.5-10 deniers is particularly suitable, and the cost is relatively low. When the viscosity of the atomized liquid is low, it is advisable to use fibers with a smaller fineness to make the liquid-conducting element, such as 1 denier, 1.5 denier, 2 denier, and 3 denier fibers. When the viscosity of the atomized liquid is high, it is advisable to use fibers with a larger fineness to make the liquid-conducting element, such as 6 denier, 10 denier, and 30 denier fibers.

[0061] like Figure 1a , 1b As shown in 1c and 1d, in this embodiment, the liquid-conducting element 200 is preferably a tubular structure formed by thermal bonding of a concentric two-component short-dimensional 2 to form a three-dimensional network. The skin layer 21 is polyethylene with a melting point of 125-135°C, and the core layer 22 is polypropylene with a melting point of 160-170°C. The density of the liquid-conducting element 200 is between 0.05-0.35 g / cm 3 The liquid-conducting element 200 has good axial strength and good radial elasticity, and has a faster liquid conduction speed. The liquid-conducting element 200 can be used for atomization of electronic cigarette liquid, and is also suitable for use in mini electric mosquito coils and aromatherapy.

[0062] In this embodiment, when the skin layer 21 of the bicomponent fiber 2 is replaced by polypropylene with a melting point of 160-170°C, the core layer of the bicomponent fiber 2 can be made of PET, PBT, PTT, polyamide, etc., and the liquid-conducting element 200 produced has higher temperature resistance. It is also possible to use PBT or PTT as the skin layer and PET as the core layer to produce a liquid-conducting element 200 with higher temperature resistance.

[0063] In another preferred embodiment of the present invention, the liquid-conducting element 200 is formed of a tubular structure of a three-dimensional network by thermal bonding of bicomponent fibers of an eccentric structure. The skin layer 21 of the liquid-conducting element 200 is polyethylene, and the core layer 22 is polypropylene or PET. The thickness of the liquid-conducting element 200 is 0.3-0.8 mm, and the density is between 0.1-0.3 g / cm 3 .

[0064] <Atomizer Core>

[0065] In this embodiment, the atomizer core includes a heating element 931, which is a porous ceramic with a pre-embedded heating wire and is designed to be tubular, and has a through hole coaxial with the aerosol channel 1303. The outer wall of the tubular liquid-conducting element 200 directly contacts the liquid in the liquid storage element 100, and the liquid penetrates axially and radially in the liquid-conducting element 200 and is conducted to the heating element 931 through the liquid-conducting element 200. The heating element 931 is connected to the wire pin 936 through the wire 933, and the wire pin 936 facilitates the connection between the aerosol bomb 800 and the external power supply.

[0066] <Liquid storage element>

[0067] The liquid storage element 100 is a component for storing liquid in the aerosol bomb 800, and the liquid to be atomized, such as electronic cigarette oil, air freshener, etc., is injected into the liquid storage element 100. The liquid storage element 100 can be a cavity made of plastic or metal, or a porous material for storing liquid is filled in the cavity. The liquid in the liquid storage element 100 is conducted to the heating element 931 through the liquid conducting element 200 and is atomized when needed. In this embodiment, the liquid storage element 100 is a cavity made of metal or plastic, into which the atomized liquid is injected. During use, as the liquid in the liquid storage element 100 is discharged, outside air can enter the liquid storage element 100 through the liquid conducting element 200 or the gap between the liquid conducting element 200 and the inner wall of the liquid storage element 100.

[0068] One end of the aerosol channel 1303 is set as the aerosol outlet 1301, and the other end of the aerosol channel 1303 abuts or is close to the heating element 931. Specifically, the outer peripheral wall of the tubular liquid guide element 200 abuts against the inner wall of the liquid storage element and covers the liquid guide hole 837; the outer peripheral wall of the heating element 931 abuts against the inner peripheral wall of the liquid guide element 200.

[0069] The outer wall of the tubular liquid-conducting element 200 directly contacts the liquid in the liquid storage element 100 . The liquid penetrates in the liquid-conducting element 200 in the axial and radial directions and is conducted to the heating element 931 through the liquid-conducting holes 837 .

[0070] <Aerosol bomb>

[0071] The bottom sealing portion 112 of the shell of the aerosol bomb 800 can be made of high temperature resistant silicone or plastic. A gap can be set between the heating element 931 and the bottom sealing portion 112 of the shell. By setting the gap, the heat conducted from the heating element 931 to the bottom sealing portion 112 of the shell can be reduced, thereby avoiding damage to the bottom sealing portion 112 of the shell due to high temperature.

[0072] The bottom sealing portion 112 of the housing is provided with a sealing portion through hole 1122 penetrating the bottom sealing portion 112 of the housing, and the sealing portion through hole 1122 is coaxially arranged with the aerosol passage 1303. The lower part of the bottom sealing portion 112 of the housing is the housing bottom plate 815, and the housing bottom plate 815 is provided with an air inlet 1121 communicating with the sealing portion through hole 1122, and an air filter element 1125 can be arranged in the air inlet 1121 to remove impurities that may exist in the incoming air.

[0073] Second embodiment

[0074] Figure 2 This is a longitudinal cross-sectional view of the aerosol bomb of the second embodiment disclosed in the present invention. 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.

[0075] like Figure 2 As shown, the aerosol bomb 800 according to the second embodiment of the present invention includes an aerosol bomb shell 810; an aerosol channel 1303 arranged inside the aerosol bomb shell 810; a shell bottom sealing portion 112 sealing the bottom of the aerosol bomb shell 810; a liquid storage element 100 formed between the aerosol bomb shell 810, the wall of the aerosol channel 1303 and the shell bottom sealing portion 112; a liquid guide hole 837 formed between the wall of the aerosol channel 1303 and the shell bottom sealing portion 112; a liquid guide element 200 arranged in the liquid storage element 100 and completely covering the liquid guide hole 837; and a heating element 931 accommodated in the liquid guide hole 837 and against the liquid guide element 200.

[0076] In this embodiment, the liquid storage element 100 is a cavity made of plastic, and the liquid is injected into the liquid storage element 100 .

[0077] In this embodiment, the liquid-conducting element 200 is formed of a tubular structure of a three-dimensional network by thermal bonding of bicomponent fibers of an eccentric structure. The skin layer 21 of the liquid-conducting element 200 is polyethylene, and the core layer 22 is polypropylene or PET. The thickness of the liquid-conducting element 200 is 0.3-0.8 mm, and the density is between 0.2-0.3 g / cm 3 .

[0078] In this embodiment, the liquid storage element 100 includes a metal cavity. The heating element 931 is a porous ceramic with a pre-embedded heating wire, and the tubular liquid conducting element 200 is coated on the periphery of the heating element 931 and is in close contact with the heating element 931. The outer peripheral wall of the liquid conducting element 200 is in contact with the liquid in the liquid storage element 100. The liquid in the liquid storage element 100 is conducted to the porous ceramic of the heating element 931 through the liquid conducting element 200. During operation, the heating wire in the heating element 931 heats up, the liquid in the porous ceramic is consumed by atomization, and is replenished from the liquid storage element 100 through the liquid conducting element 200.

[0079] A gap is provided between the heating element 931 and the bottom sealing portion 112 of the housing. The gap is filled with a silicone spacer 8371. The silicone spacer 8371 is resistant to high temperatures and can further prevent the bottom sealing portion 112 of the housing from overheating.

[0080] The bottom of the aerosol bomb housing 810 is provided with a bottom plate 815, and a buffer chamber 953 is provided between the bottom plate 815 and the bottom sealing portion 112 of the housing. Oil-absorbing cotton can also be provided in the buffer chamber 953. The provision of the buffer chamber 953 and the oil-absorbing cotton can effectively prevent the liquid in the aerosol bomb 800 from leaking.

[0081] The inner diameter of the portion of the aerosol passage 1303 close to the aerosol outlet 1301 can be set to be smaller than the inner diameter of the portion close to the heating element 931. With such a structure, the portion close to the heating element 931 can be formed into a larger cavity, which is more conducive to the atomization and dispersion of the liquid.

[0082] In summary, the aerosol bomb of the present invention has a simpler structure, is easier to assemble, is conducive to automated assembly, and has lower costs. The aerosol bomb according to the present invention can be used in disposable electronic cigarettes and cigarette bombs, and is very suitable for large-capacity electronic cigarettes. The liquid-conducting element for the aerosol bomb involved in the present invention is made of two-component fiber bonding and can be widely used in various types of aerosol bombs. The liquid-conducting element has good strength, is suitable for automated assembly, and greatly improves the production efficiency of the aerosol bomb. The liquid-conducting element can smoothly and quickly conduct the liquid to the heating element, thereby improving the atomization efficiency and stability.

[0083] The above embodiments are merely 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 departing from 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 by the present invention should still be covered by the claims of the present invention.
