First embodiment
FIG. 1a is a longitudinal cross-sectional view of an air guide element according to a first embodiment of the disclosed invention; FIG. 1b is a cross-sectional view of an air guide element according to a first disclosed embodiment of the invention; FIG. 1c is an enlarged schematic cross-sectional view of the bicomponent fiber of FIGS. 1a and 1 b; FIG. 1d is an enlarged cross-sectional schematic view of another bicomponent fiber of FIGS. 1a and 1 b; fig. 1e is a longitudinal cross-sectional view of a first disclosed embodiment of an aerosol dispensing device.
As shown in fig. 1a to 1e, an air-directing element 600 according to a first embodiment of the present invention for use in an aerosol dispensing device 1 for directing air from a liquid storage component 100 and controlling the amount of air entering the liquid storage component 100, the air-directing element 600 having an air-directing element first surface 610 for contacting liquid in the liquid storage component 100 and being wetted by the liquid, and an air-directing element second surface 620 for directly contacting air outside the liquid storage component 100, the air-directing element 600 being formed by bonding bicomponent fibers 2 to form a three-dimensional network, the bicomponent fibers 2 having a sheath 21 and a core 22.
The cross section of the air guide element 600 may be designed into a desired shape, such as a semicircle, a segment, a circular ring, an elliptical ring, etc., according to the inner space of the liquid storage element 100.
< Density of air guide elements >
The air guide element 600 of this embodiment has a density of 0.03-0.095 g/cm3For example, 0.03 g/cm30.045 g/cm30.05 g/cm30.065 g/cm30.07 g/cm30.08 g/cm30.095 g/cm3Preferably 0.045 to 0.08 g/cm3. When the density is less than 0.03 g/cm3The air guide element 600 is difficult to manufacture, and too weak to install. When the density is more than 0.095/cm3When the air guide element 600 is used, the air guide is difficult to wet by liquid due to small capillary gaps, which easily causes the heating element 930 to be burnt due to insufficient liquid supply. In the preferred range of 0.045 to 0.08 g/cm3The gas directing element 600 has the most suitable gas and liquid directing properties within the density range and is moderately strong for ease of installation.
< thickness of air guide element >
The thickness of the air guide element 600 is defined as the shortest distance between the portion of the air guide element 600 that contacts the liquid inside the liquid storage element 100 and the portion that contacts the air outside the liquid storage element 100. The air guide element 600 has a thickness of 2 mm to 15 mm, such as 2 mm, 4 mm, 6 mm, 8 mm, 10 mm, 12 mm, 15 mm, and preferably 4 mm to 12 mm. When the thickness of the air guide element 600 is less than 2 mm, the air guide element 600 is too weak to be easily installed. When the thickness of the air guide member 600 is larger than 15 mm, the air guide member 600 occupies too much space in the liquid storage member 100, and the air guide member 600 having too large a thickness may affect the air guide efficiency.
< bicomponent fiber >
FIG. 1c is an enlarged cross-sectional schematic view of the bicomponent fiber of FIGS. 1a and 1 b. As shown in fig. 1c, the skin layer 21 and the core layer 22 are of a concentric structure. FIG. 1d is another enlarged cross-sectional schematic view of the bicomponent fiber of FIGS. 1a and 1 b. As shown in fig. 1d, the skin layer 21 and the core layer 22 are of an eccentric structure. The air guide member 600 made of the concentrically structured bicomponent fibers 2 is relatively rigid, and the air guide member 600 made of the eccentrically structured bicomponent fibers 2 is relatively elastic.
The bicomponent fibers 2 may be selected to be either filaments or staple fibers depending on the manufacturing technique of the air guide element 600. Preferably, the core layer 22 of the bicomponent fiber 2 has a melting point higher than that of the sheath layer 21 by 20 ℃ or more. The air guide 600 of this embodiment is made of sheath-core bicomponent fibers 2 bonded by means of thermal bonding, adhesive bonding or plasticizer bonding, preferably thermal bonding to obtain a clean air guide 600. The core layer 22 of the bicomponent fiber 2 has a melting point higher than that of the sheath layer 21 by more than 20 ℃, so that the core layer 22 can keep certain rigidity during thermal bonding between fibers, and the air guide element 600 with uniform gaps can be conveniently manufactured.
The sheath layer 21 of the bicomponent fiber 2 may be polyolefin such as polyethylene and polypropylene, or may be common polymer such as polyamide, polyester, polylactic acid, or low-melting copolyester. When the skin layer 21 is polyethylene, the core layer 22 may be a polymer such as polypropylene, polyethylene terephthalate, PET for short, or the like. When the skin layer 21 is polyamide, the core layer 22 may be PET or the like.
The bicomponent fibers 2 making the air guide element 600 of the present invention have a denier of between 1 and 30, for example, 1, 1.5, 3, 4.5, 6, 7.5, 9, 10, 12, 15, 18, 21, 24, 27, 30, preferably 1.5 to 10 denier. Bicomponent fibers 2 having a sheath-core structure of less than 1 denier are difficult and costly to manufacture. Air guide elements 600 made of fibers above 30 denier have insufficient capillary force and poor liquid conductivity. Sheath-core bicomponent fibers 2 of between 1 and 30 denier are easy to make into air guide 600, with sheath-core bicomponent fibers 2 of between 1.5 and 10 denier being particularly suitable and less costly.
As shown in fig. 1c, in the present embodiment, it is preferable that the air guide member 600 is formed in a three-dimensional network structure by thermally bonding two short fibers 2 of a concentric structure. The skin layer 21 is polyethylene with melting point of 125-135 deg.C, the core layer 22 is polypropylene with melting point of 160-170 deg.C, and the density of the gas guide element 600 is 0.045-0.08 g/cm3The air guide member 600 has good strength and flexibility, is easy to install, and has a fast liquid transfer rate. Such an air guide element 600 may be used for electronic cigarettes, electric mosquito coils, or electric aromatherapy.
< Aerosol dispensing device >
As shown in FIG. 1e, the aerosol dispensing device 1 according to this embodiment comprises a power source 910, a control circuit 920, a heating element 930, a liquid reservoir 100, and the air directing member 600 described above, wherein the first surface 610 of the air directing member contacts and is wetted by the liquid in the liquid reservoir 100, and the second surface 620 of the air directing member is in direct contact with the air outside the liquid reservoir 100, and the air must pass through the air directing member 600 to enter the liquid reservoir 100. That is, the liquid storage element 100 controls the amount of air that enters the liquid storage element 100 only through the air directing element 600.
The liquid storage component 100 is a component for storing liquid in the aerosol dispensing device 1, and the liquid to be atomized, such as electronic cigarette liquid, cannabidiol solution, air freshener, etc., is injected into the liquid storage component 100. When atomized as needed, the liquid in the liquid storage element 100 is either directly contacted by the heating element 930 or conducted through the air directing element 600 to the heating element 930. The liquid storage element 100 in this embodiment is a cavity made of metal or plastic, or a porous material filled in the cavity for storing liquid. The reservoir member 100 has a reservoir member through bore 130 extending axially through the reservoir member 100, the reservoir member through bore 130 serving as an aerosol passage 1303 for escape of an aerosol gas from the aerosol dispensing device 1.
In this embodiment, the reservoir element through hole 130 is made up of a small diameter reservoir element through hole distal to the heating element 930 and a large diameter reservoir element through hole proximal to the heating element 930. An annular mounting space for the air guide member 600 is formed between the peripheral wall of the large-diameter liquid storage member through hole and the outer peripheral wall of the liquid storage member 100.
The air guide element 600 is provided with an air guide element through hole 630 which axially penetrates through the air guide element 600, the air guide element 600 is sleeved on the outer peripheral wall of the large-diameter liquid storage element through hole of the liquid storage element through hole 130 through the air guide element through hole 630, no air guide gap is arranged between the air guide element 600 and the wall of the liquid storage element 100, and the liquid storage element 100 only controls the amount of air entering the liquid storage element 100 through the air guide element 600.
Further, an annular mounting space for the air guide member 600 is formed between the peripheral wall of the large-diameter liquid storage member through hole and the peripheral wall of the liquid storage member 100, and may be partially closed, leaving only a part of the mounting space. For example, the bottom of the installation space of the liquid storage element 100 is sealed with a bottom plate by one quarter, or one half, and accordingly, the air guide element 600 is formed in a suitable shape, such as three quarters cylindrical shape, or one half cylindrical shape.
The aerosol dispensing device 1 further comprises a host housing 950 and a host spacer 951, which may be used to mount the heating element 930 and may enclose the power supply 910 and control circuitry 920 within the aerosol dispensing device 1.
Wire 933 of heating element 930 is electrically coupled to power supply 910 through host spacer 951.
The aerosol dispensing device 1 further includes a buffer chamber 953, and when the external environment changes, liquid from the reservoir 100 can enter the buffer chamber 953. The buffer chamber 953 is a cavity surrounded by the main machine partition 951, the main machine housing 950, the heating element 930, the supporting part 935, and the air guide element 600. In the following embodiments, the host spacer 951 and the support member 935 may be integrally formed or may be provided separately. When provided separately, the support member 935 may fit over the host spacer 951.
In this embodiment, the air guide element second surface 620 is in contact with the heating element 930, but the heating element 930 only partially covers the air guide element second surface 620, such that the air guide element second surface 620 is in direct contact with the air outside of the liquid storage element 100. The liquid in the liquid storage component 100 wets the air guide member first surface 610 and conducts the liquid in the liquid storage component 100 through the air guide member 600 to the heating element 930.
When the aerosol dispensing device 1 is in operation, the air stream passes through the heating element 930 and the heating wire heats up, and liquid conducted from the reservoir 100 to the heating element 930 is atomized and exits through the aerosol passage 1303 of the aerosol dispensing device 1. The liquid consumed on the heating element 930 is replenished by the liquid storage element 100 through the air directing element 600. Because the air guide element 600 has a three-dimensional network structure with a large number of capillary pores, the liquid in the liquid storage element 100 can be rapidly conducted to the heating element 930 through the air guide element 600, thereby enabling the heating element 930 to generate a stable aerosol during operation.
With the progress of atomization, liquid in the liquid storage element 100 is continuously consumed, negative pressure is generated in the liquid storage element 100, pressure difference is formed between the inside and the outside of the liquid storage element 100, when the pressure difference reaches a certain degree, outside air penetrates through the air guide element 600 to enter the liquid storage element 100, and the process is repeated until the liquid is used up.
When the aerosol dispensing device 1 is subjected to an elevated temperature or reduced ambient pressure during storage and transportation, the air expands within the reservoir 100 and some of the liquid is forced out of the reservoir 100. If the buffer chamber 953 is provided in the aerosol dispenser 1, the liquid pushed out can enter the buffer chamber 953, and the liquid is prevented from leaking to the outside.
