Abstract
Description
Technical Field
[0001] The present invention relates to an aerosol atomization device with a liquid guiding element, and particularly to an aerosol atomization device with a liquid guiding element for vaporizing or atomizing a liquid, such as an electronic cigarette, an electric mosquito repellent, an electric aromatherapy device, and a drug atomization inhalation device. Background Art
[0002] Aerosol atomization devices are widely used in various fields of daily life, such as electronic cigarettes, electric mosquito repellents, electric aromatherapy devices, and drug atomization inhalation devices. A common structure is to install an atomization core in the aerosol atomization device, such as a porous ceramic embedded with an electric heating wire. When air flows through the atomization device, the atomization core is heated, and the liquid is atomized and carried out by the air flow. In order to smoothly conduct the liquid in the liquid storage part to the atomization core and prevent liquid leakage, a non-woven fabric is usually coated on the surface of the atomization core and fixed in the aerosol atomization device. Since the non-woven fabric is soft and lacks strength, it is easy to wrinkle, and it is difficult to manufacture an aerosol atomization device with stable quality. In the case of serious wrinkles, liquid leakage is likely to occur. The method of coating the non-woven fabric on the surface of the atomization core requires a large amount of manual labor, is difficult to automate, has high costs and low efficiency. Similar problems also exist in aerosol atomization devices for vaporizing or atomizing liquids, such as electric mosquito repellents, electric aromatherapy devices, and drug atomization inhalation devices. Summary of the Invention
[0003] To solve the problems existing in the prior art, the present invention provides an aerosol atomization device with a liquid guiding element. The aerosol atomization device with a liquid guiding element includes a power supply, a control circuit, a heating element, a liquid storage element, and a liquid guiding element. The liquid guiding element is arranged between the heating element and the liquid storage element.
[0004] Furthermore, the liquid storage element has a liquid storage element through hole axially penetrating the liquid storage element. A heating element connection port is arranged on the inner wall of the liquid storage element through hole. The liquid guiding element is arranged between the heating element and the heating element connection port of the liquid storage element.
[0005] Furthermore, the aerosol atomization device with a liquid guiding element further includes a main body housing and a liquid storage element housing. The gap between the main body housing and the liquid storage element housing forms an aerosol channel.
[0006] Furthermore, the liquid guiding element is formed by thermally bonding a bicomponent fiber to form a three-dimensional network three-dimensional structure. The bicomponent fiber has a skin layer and a core layer.
[0007] Furthermore, the liquid guiding element has a liquid guiding element through hole axially penetrating the liquid guiding element.
[0008] Furthermore, the liquid guiding element is sheet-shaped or tubular.
[0009] Furthermore, the axial rigidity of the liquid guiding element is greater than its radial rigidity.
[0010] Furthermore, the axial penetration rate of the liquid in the liquid guiding element is greater than the radial penetration rate of the liquid.
[0011] Furthermore, the radial rigidity of the liquid guiding element is greater than its axial rigidity.
[0012] Furthermore, the radial penetration rate of the liquid in the liquid guiding element is greater than the axial penetration rate of the liquid.
[0013] Furthermore, the thickness of the liquid guiding element is 0.3 mm - 3 mm.
[0014] Furthermore, the density of the liquid guiding element is 0.05 g / cm 3 - 0.35 g / cm 3 .
[0015] Furthermore, the skin layer and the core layer of the bicomponent fiber are in a concentric structure or an eccentric structure.
[0016] Furthermore, the melting point of the core layer of the bicomponent fiber is more than 20 °C higher than that of the skin layer.
[0017] Furthermore, the skin layer of the bicomponent fiber is polyolefin, copolyester of polyethylene terephthalate, polypropylene terephthalate, polybutylene terephthalate, polylactic acid or polyamide-6.
[0018] Furthermore, the core layer of the bicomponent fiber is polylactic acid.
[0019] The liquid guiding element made of the bonded bicomponent fiber has high strength and toughness, is not prone to wrinkling or breaking during installation, can be easily assembled in the aerosol emitting device, is easy to realize assembly automation, improves efficiency and saves costs. It is especially suitable for manufacturing large-scale consumer products, such as electronic cigarettes, etc. Since the bicomponent fiber bonds to form a three-dimensional network structure, a large number of interconnected capillary pores are formed in the liquid guiding element. These capillary pores are beneficial for the rapid and stable conduction of the liquid therein, improving the stability of replenishing the liquid for the atomization core, thereby improving the atomization stability. By selecting the fiber fineness and setting the density of the liquid guiding element, the size of the capillary pores and the capillary force can be controlled, making the liquid guiding element suitable for the requirements of different aerosol emitting devices.

[0047] First Embodiment
[0048] Figure 1a is a longitudinal sectional view of the liquid guiding element of the first embodiment disclosed in the present invention; Figure 1b is a cross-sectional view of the liquid guiding element of the first embodiment disclosed in the present invention; Figure 1c is Figure 1a and 1b is an enlarged schematic cross-sectional view of a bicomponent fiber in Figure 1d is Figure 1a and 1b is another enlarged schematic cross-sectional view of a bicomponent fiber in Figure 1e is a longitudinal sectional view of an aerosol dispersion device with a liquid guiding element of the first embodiment disclosed in the present invention; Figure 1f is for Figure 1e is an enlarged longitudinal sectional view of the through hole of the liquid storage element in
[0049] As Figures 1a to 1e shown, an aerosol dispersion device with a liquid guiding element according to the first embodiment of the present invention includes a power source 910, a control circuit 920, a heating element 930, a liquid storage element 100, and a liquid guiding element 200. The liquid guiding element 200 is disposed between the heating element 930 and the liquid storage element 100.
[0050] In this embodiment, as Figure 1e and 1f shown, the liquid storage element 100 has a liquid storage element through hole 130 axially penetrating the liquid storage element 100. A heating element connection port 1302 is provided on the inner wall of the liquid storage element through hole 130. The liquid guiding element 200 is disposed between the heating element 930 and the heating element connection port 1302 of the liquid storage element 100.
[0051] One side of the liquid guiding element 200 contacts the liquid in the liquid storage element 100, and the other side contacts the heating element 930. Thus, the liquid guiding element 200 conducts the liquid to the heating element 930.
[0052] As Figures 1a to 1dAs shown, the liquid guiding element 200 according to the first embodiment of the present invention is used to conduct liquid in an aerosol dispensing device having a liquid guiding element. The liquid guiding element 200 is formed into a three-dimensional network three-dimensional structure by thermally bonding the bicomponent fibers 2. The bicomponent fibers 2 have a skin layer 21 and a core layer 22.
[0053] <Shape, thickness, rigidity and liquid penetration speed of the liquid guiding element>
[0054] The liquid guiding element 200 may have a liquid guiding element through hole 230 axially penetrating the liquid guiding element 200.
[0055] For the liquid guiding element 200 of this embodiment, according to the design of the aerosol dispensing device having a liquid guiding element, the liquid guiding element 200 can be designed into a sheet shape or a tubular shape. As Figure 1a and Figure 1b shown, the liquid guiding element 200 in this embodiment is set as a tubular shape.
[0056] The liquid guiding element 200 can also be designed into a sheet shape. The sheet-shaped liquid guiding element 200 can also be provided with a liquid guiding element through hole 230.
[0057] According to the structure of the aerosol dispensing device having a liquid guiding element, the cross-section of the liquid guiding element 200 can be made into a circular ring shape, an elliptical ring shape or other required shapes.
[0058] For the sheet-shaped liquid guiding element 200, the axial direction is defined as its thickness direction herein, and the radial direction is defined as the direction perpendicular to the thickness. By using appropriate manufacturing techniques, the fibers can have more axial alignment orientations in the liquid guiding element 200. In this case, the axial rigidity of the sheet-shaped liquid guiding element 200 is greater than its radial rigidity, and the liquid penetration speed along the axial direction in the liquid guiding element 200 is greater than the liquid penetration speed along the radial direction; it is also possible to make the fibers have more radial alignment orientations in the liquid guiding element 200. In this case, the radial rigidity of the sheet-shaped liquid guiding element 200 is greater than its axial rigidity, and the liquid penetration speed along the radial direction in the liquid guiding element 200 is greater than the liquid penetration speed along the axial direction.
[0059] For the tubular liquid guiding element 200, the axial direction is defined as the direction of the central axis of the liquid guiding element through hole 230 herein, and the radial direction is defined as the direction perpendicular to the central axis of the liquid guiding element through hole 230. In the tubular liquid guiding element 200, the fibers have more axial alignment orientations, the axial rigidity of the liquid guiding element 200 is greater than its radial rigidity, and the liquid penetration speed along the axial direction in the liquid guiding element 200 is greater than the liquid penetration speed along the radial direction.
[0060] The rigid comparison method in this article is as follows: Place the liquid guiding element 200 axially or radially, clamp it between two parallel plates, and measure the axial height or radial height of the liquid guiding element 200 before compression; under the condition of applying the same force, measure the axial height or radial height of the liquid guiding element 200 after the two plates axially or radially compress the liquid guiding element 200, and calculate the amount of 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 amount of compression deformation by the axial height or radial height of the liquid guiding element 200 before compression to obtain the compression ratio. The smaller the compression ratio, the greater the rigidity; the larger the compression ratio, the smaller the rigidity.
[0061] The thickness of the liquid guiding element 200 refers to the shortest distance for the liquid to conduct from one side of the liquid guiding element 200 to the other side. The thickness of the tubular liquid guiding element 200 is the thickness of the tube wall, and the thickness of the sheet-like liquid guiding element 200 is the thickness in its thickness direction.
[0062] The thickness of the liquid guiding element 200 is 0.3 mm - 3 mm, preferably 0.6 mm, 0.9 mm, 1.2 mm, 1.5 mm, 2 mm. When the thickness of the liquid guiding element 200 is less than 0.3 mm, it is difficult to fabricate a uniform liquid guiding element 200 and it is not convenient for installation. When the thickness of the liquid guiding element 200 is greater than 3 mm, the liquid guiding element 200 occupies too much space in the aerosol emitting device with the liquid guiding element. Especially for the tubular liquid guiding element 200, it is usually difficult to install in a small aerosol emitting device with the liquid guiding element when the thickness is greater than 3 mm. In addition, when the thickness is greater than 3 mm, the liquid guiding element 200 absorbs too much liquid, affecting the utilization efficiency of the liquid.
[0063] In this embodiment, the fibers in the tubular liquid guiding element 200 have more axial alignment orientations, the axial rigidity is greater than the radial rigidity, and it has good elasticity in the radial direction, which is beneficial to applying force axially when installing the liquid guiding element 200 and using the radial elasticity of the liquid guiding element 200 to closely fit the liquid guiding element 200 with the heating element 930 and the liquid guiding element 200 with the atomizer housing.
[0064] <Density of the liquid guiding element>
[0065] The density of the liquid guiding element 200 in 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 , the strength of the liquid guiding element 200 is insufficient. When the tubular liquid guiding element 200 is assembled with the aerosol emitting device with the liquid guiding element, it is easy to deform or even wrinkle, affecting the stability of atomization, and even causing liquid leakage in severe cases. When the density is greater than 0.35 g / cm 3When the liquid guiding speed is slow, it affects the atomization efficiency. Moreover, the hardness of the high-density liquid guiding element is too high, the radial elasticity is insufficient, and the compatibility between the tubular liquid guiding element and the aerosol dispersion device with the liquid guiding element decreases.
[0066] <Bicomponent fiber>
[0067] Figure 1c is Figure 1a and 1b An enlarged cross-sectional schematic diagram of a kind of bicomponent fiber in Figure 1c As shown, the skin layer 21 and the core layer 22 are concentric structures. Figure 1d is Figure 1a and 1b Another enlarged cross-sectional schematic diagram of the bicomponent fiber in Figure 1d As shown, the skin layer 21 and the core layer 22 are eccentric structures. The liquid guiding element made of the concentric-structured bicomponent fiber 2 has greater rigidity, and the liquid guiding element 200 made of the eccentric-structured bicomponent fiber 2 has better elasticity.
[0068] The bicomponent fiber 2 is a filament or staple fiber. The liquid guiding element 200 made of filaments has greater rigidity, and the liquid guiding element 200 made of staple fibers has better elasticity. The appropriate liquid guiding element 200 can be selected according to the performance requirements of the liquid guiding element 200.
[0069] The melting point of the core layer 22 of the bicomponent fiber 2 is more than 20 °C higher than that of the skin layer 21. The liquid guiding element 200 of this embodiment is made by thermally bonding the skin-core structured bicomponent fiber 2. The melting point of the core layer 22 of the bicomponent fiber 2 being more than 20 °C higher than that of the skin layer 21 can keep the core layer 22 having a certain rigidity when thermally bonding between the fibers, which is convenient for making a liquid guiding element 200 with uniform voids.
[0070] The skin layer 21 of the bicomponent fiber 2 can be polyolefin, copolyester of polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polylactic acid or polyamide-6. Polyolefin is a polymer of olefins, generally referring to a general term for a class of thermoplastic resins obtained by polymerizing α-olefins such as ethylene, propylene, 1-butene, 1-pentene, 1-hexene alone or copolymerizing. It can also be common polymers such as polyester or low-melting copolyester.
[0071] When the skin layer 21 is polyethylene, the core layer 22 can be polymers such as polypropylene, polyethylene terephthalate (abbreviation: PET), etc. When the skin layer 21 is polypropylene, the core layer 22 can be PET, polyamide, etc. The lower melting point of the skin layer 21 of the bicomponent fiber 2 is beneficial to improving production efficiency and reducing manufacturing costs. The higher melting point of the skin layer 21 of the bicomponent fiber 2 makes the liquid guiding element have higher heat resistance performance, which is beneficial to increasing the working temperature of the atomization core.
[0072] 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 can be 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 (abbreviation: PBT), polypropylene terephthalate (abbreviation: PTT), polyamide, etc. Polylactic acid is a biodegradable material, which can reduce environmental pollution caused when the liquid guiding element is discarded.
[0073] 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, if the skin layer 21 uses PBT or PTT with a melting point of 225-235°C, the core layer 22 can use PET with a melting point of 255-265°C. Another example is that the skin layer is a copolyester of polyethylene terephthalate (abbreviation: Co-PET) with a melting point of 110-120°C or 160-200°C, and the core layer can use PET, PBT or PTT.
[0074] The fineness of the bicomponent fiber 2 for manufacturing the liquid guiding element 200 of the present invention is between 1-30 denier, preferably 1.5-10 denier. It is difficult and costly to manufacture a skin-core structured bicomponent fiber 2 with a fineness less than 1 denier. The liquid guiding element 200 made of fibers with a fineness higher than 30 denier has insufficient capillary force and poor liquid guiding performance. It is easy to manufacture the liquid guiding element 200 with a skin-core structured bicomponent fiber 2 between 1-30 denier, and the skin-core structured bicomponent fiber 2 with a fineness of 1.5-10 denier is particularly suitable and has a lower cost. When the viscosity of the atomized liquid is low, it is advisable to use fibers with a smaller fineness to manufacture the liquid guiding element, such as fibers with a fineness of 1 denier, 1.5 denier, 2 denier, or 3 denier. When the viscosity of the atomized liquid is high, it is advisable to use fibers with a larger fineness to manufacture the liquid guiding element, such as fibers with a fineness of 6 denier, 10 denier, or 30 denier.
[0075] As Figure 1a 、 1b As shown in 1c and 1d, in this embodiment, it is preferred that the liquid guiding element 200 is formed into a three-dimensional network tubular three-dimensional structure by thermal bonding of the concentric-structured bicomponent short fibers 2. 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 manufactured liquid guiding element 200 is between 0.05-0.35 g / cm 3 , and this kind of liquid guiding element 200 has good axial strength and good radial elasticity, and has a fast liquid conduction speed. This kind of liquid guiding element 200 can be used for the atomization of e-cigarette liquid, the atomization of cannabidiol or tetrahydrocannabinol solution, and is also suitable for use in mini electric mosquito coils and aromatherapy.
[0076] In this embodiment, when the skin layer 21 of the bicomponent fiber 2 is replaced with polypropylene having 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 guiding element 200 thus formed has high temperature resistance. PBT or PTT can also be used as the skin layer and PET as the core layer to make a liquid guiding element 200 with even higher temperature resistance.
[0077] In another preferred mode of this embodiment, the liquid guiding element 200 is formed into a three-dimensional network tubular structure by thermally bonding bicomponent fibers with an eccentric structure. The skin layer 21 of the liquid guiding element 200 is polyethylene, and the core layer 22 is polypropylene or PET. The thickness of the liquid guiding element 200 thus made is 0.3-0.8 mm, and the density is between 0.1-0.3 g / cm 3 .
[0078] <Heating element>
[0079] In this embodiment, the heating element 930 is a porous ceramic embedded with an electric heating wire and is designed to be tubular, and is provided with a wire 933. A part of the outer wall of the tubular liquid guiding element 200 is in direct contact with the liquid in the liquid storage element 100. The liquid penetrates axially and radially in the liquid guiding element 200 and is conducted to the heating element 930 through the liquid guiding element 200. The heating element 930 is connected to the power supply 910 in the aerosol emitting device 1 having a liquid guiding element through the wire 933.
[0080] <Liquid storage element>
[0081] The liquid storage element 100 is a component in the aerosol emission device 1 with a liquid guiding element for storing liquid. The liquid to be atomized, such as e-cigarette oil, cannabidiol solution, 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 930 through the liquid guiding element 200 and is atomized when needed. In this embodiment, the liquid storage element 100 is a cavity made of metal or plastic, and the atomized liquid is injected therein. When in use, as the liquid in the liquid storage element 100 is exported, external air can enter the liquid storage element 100 through the liquid guiding element 200 or the gap between the liquid guiding element 200 and the inner wall of the cavity of the liquid storage element 100. The liquid storage element 100 has a liquid storage element through hole 130 axially penetrating the liquid storage element 100. One end of the liquid storage element through hole 130 is set as the aerosol outlet 1301, and a heating element connection port 1302 is arranged on the inner wall of the liquid storage element through hole 130 near the other end. The liquid guiding element 200 is arranged between the heating element 930 and the heating element connection port 1302 of the liquid storage element 100. Specifically, the outer peripheral wall of the tubular liquid guiding element 200 abuts against the inner peripheral wall of the liquid storage element through hole 130 and covers the heating element connection port 1302; the outer peripheral wall of the heating element 930 abuts against the inner peripheral wall of the liquid guiding element 200. Thus, the liquid guiding element 200 is arranged between the heating element 930 and the liquid storage element 100.
[0082] A part of the outer wall of the tubular liquid guiding element 200 directly contacts the liquid in the liquid storage element 100 through the heating element connection port 1302. The liquid penetrates axially and radially in the liquid guiding element 200 and is conducted to the heating element 930 through the liquid guiding element 200.
[0083] <Aerosol emission device with a liquid guiding element>
[0084] Such as Figure 1e As shown, the aerosol emission device 1 with a liquid guiding element according to this embodiment includes a power supply 910, a control circuit 920, a heating element 930, a liquid storage element 100, and a liquid guiding element 200. The liquid guiding element 200 is arranged between the heating element 930 and the liquid storage element 100.
[0085] The aerosol emission device 1 with a liquid guiding element further includes a main body housing 950 and a main body partition 957. The main body partition 957 can be used to install the heating element 930 and can also encapsulate components such as the power supply 910 and the control circuit 920 inside the aerosol emission device 1 with a liquid guiding element.
[0086] The wire 933 of the heating element 930 passes through the main body partition 957 and is electrically connected to the power supply 910.

This embodiment is similar in structure to the first embodiment, and the same parts as those in the first embodiment will not be described again in the description of this embodiment.
[0089] As Figures 2a to 2e shown, the aerosol dispersion device with a liquid guiding element according to the second embodiment of the present invention includes a power source 910, a control circuit 920, a heating element 930, a liquid storage element 100, and a liquid guiding element 200.

During operation, the thick film heating element of the heating element 930 heats up, and the liquid in the porous ceramic is atomized and consumed, and is replenished from the liquid storage element 100 through the liquid guiding element 200. Preferably, the radial rigidity of the sheet-like liquid guiding element 200 is greater than its axial rigidity, and the speed of the liquid permeating along the radial direction in the liquid guiding element 200 is greater than the speed of the liquid permeating along the axial direction, which is beneficial to the liquid in the liquid storage element 100 to converge to the contact part of the liquid guiding element 200 and the heating element 930 through the liquid guiding element 200.
