Description

Aerial fog bomb

Technical Field

The invention relates to an aerosol bomb, in particular to an aerosol bomb comprising a capillary channel relay liquid guide element, which is used in the application fields of electronic cigarettes, medicine solution atomization and the like.

Background

The technology of atomizing liquid has been widely used in the fields of electronic cigarettes and the like. A common technique in electronic atomized cigarettes is to heat an atomizing core liquid-conducting element, such as a glass fiber bundle or a cotton fiber bundle, that is in direct communication with the tobacco tar, to atomize the liquid. The atomization chamber cavity and the atomization core liquid guide element need to be matched properly, so that external air enters the liquid storage element from a gap between the atomization core liquid guide element and the atomization chamber cavity while liquid is conducted from the atomization core liquid guide element. Because fine bundle of glass and cotton tow are soft and lack fixed shape for the clearance between atomizing core drain component and the atomizer chamber cavity is difficult with accurate control, and the liquid on the atomizing core is too much when the clearance is too big, can explode oil during the atomizing, can the weeping when serious, and the air is difficult to get into the stock solution component when the clearance is undersize, and then leads to atomizing core to lack liquid and paste the core, and these all influence atomizing stability and consumption experience.

According to a known aerosol bomb with an air-liquid channel, the air-liquid channel comprises a fluid core body made of bonded fibers, liquid is conducted to the atomizing core by the fluid core body, and the liquid seal of the air-liquid channel is controlled by the absorption and release of the liquid by the fluid core body, so that the atomizing process is controlled. When liquid is led out from the liquid storage element, negative pressure in the liquid storage element is increased, the liquid in the gas-liquid channel is absorbed by the fluid core body, the liquid seal of part or all of the gas-liquid channel disappears, air in the atomizing chamber enters the liquid storage element through the gas-liquid channel, and when the vacuum degree in the liquid storage element is reduced to a balance state, the gas-liquid channel is sealed again. In the technology, because the liquid flow path in the fiber-bonded fluid core is relatively tortuous, the liquid flow speed is relatively low, and particularly when the temperature is relatively low, the viscosity of the electronic cigarette liquid mainly containing propylene glycol and glycerin is relatively high, the atomized core is easy to cause insufficient liquid supply to influence the taste and even paste the core.

< liquid guide element for capillary channel Relay >

In this embodiment, as shown in fig. 1a, a capillary passage relay liquid guiding element 939 is disposed in the atomizing chamber 934, and the liquid storage element 100 and the atomizing core 930 are communicated with each other by the capillary passage relay liquid guiding element 939. As shown in fig. 1b to 1h, the capillary passage intermediate liquid guiding element 939 comprises at least 2 axially penetrating capillary passages 9392, and the capillary passages 9392 transport liquid from the liquid storage element 100 to the atomizing core liquid guiding element 932 by their capillary force.

In the present invention, the wall surface of the capillary channel 9392 can be wetted by the liquid in the liquid storage element 100, that is, the capillary channel 9392 has an inner peripheral wall that can be wetted by the liquid, and a person skilled in the art can make the inner peripheral wall of the capillary channel 9392 wettable by the liquid through the selection of materials, or the inner peripheral wall of the capillary channel 9392 is processed, or a hydrophilic material is coated or added on the inner peripheral wall of the capillary channel 9392.

Liquid can flow in capillary channel 9392 under the surface tension of the liquid and the capillary force of atomizing wick wicking element 932. The capillary passage 9392 in the capillary passage relay liquid guide element 939 is arranged in a straight line or nearly straight line along the axial direction, that is, the capillary passage 9392 in the capillary passage relay liquid guide element 939 is parallel or substantially parallel to the axial direction of the capillary passage relay liquid guide element 939, so that the liquid can flow in the capillary passage 9392 along the axial direction, and this structure is beneficial to reducing the liquid guide resistance and reducing the risk of the atomizing core 930 being starved.

Capillary channel relay liquid guiding member 939 may comprise radially closed capillary channels 9392 or peripherally closed capillary channels 9392, as shown in fig. 1b, 1c, 1 d. Capillary channel relay liquid guiding member 939 may also comprise radially open capillary channels 9392 or peripherally open capillary channels 9392 as shown in fig. 1e, 1f, 1 g. Capillary channel relay liquid guiding element 939 may also comprise both radially closed capillary channels 9392 and radially open capillary channels 9392, as shown in fig. 1 h. A relay liquid guiding member outer tube 9393 may be provided outside the radially open capillary passage relay liquid guiding member 939, the length of the relay liquid guiding member outer tube 9393 being equal to the capillary passage relay liquid guiding member 939, so that the radially open capillary passage relay liquid guiding member 939 becomes the radially closed capillary passage relay liquid guiding member 939, as shown in fig. 1 i. It is also possible to make the length of the relay liquid guiding element outer tube 9393 smaller than the capillary channel relay liquid guiding element 939, so that a part of the capillary channel 9392 which is radially open becomes radially closed, as shown in fig. 1 j. The liquid guiding member 939 in the capillary passage can be made of plastic or metal by injection molding or extrusion. In addition to capillary passage 9392 being capable of conducting liquid, other portions of capillary passage relay liquid guiding member 939 do not have a liquid guiding function.

The capillary channel relay liquid guiding element 939 can directly communicate the liquid storage element 100 and the atomizing core liquid guiding element 932, and the connection mode is simple. The relay buffer liquid storage portion 938 may be disposed in the atomizing chamber 934, the capillary channel relay liquid guiding element 939 is communicated with the atomizing core liquid guiding element 932 through the relay buffer liquid storage portion 938, the relay buffer liquid storage portion 938 plays a role of temporarily storing liquid in the connection mode, and the risk of liquid shortage of the atomizing core 930 can be reduced in a short time under the condition of a large amount of atomization. In the event of an abnormal condition, such as an external negative pressure, the relay buffer reservoir 938 may absorb a small amount of liquid leaking from the reservoir element 100, thereby preventing liquid from leaking from the cartridge 800.

The size of the capillary passage 9392 in the capillary passage relay liquid guiding member 939 is expressed by the maximum inscribed circle diameter of the smallest cross section in the capillary passage 9392, and the sizes of the different capillary passages 9392 in one capillary passage relay liquid guiding member 939 may be the same or different. The smallest cross section of capillary passage 9392 has a maximum inscribed circle diameter of 0.1mm to 0.8mm, such as 0.1mm, 0.15mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.8mm, preferably 0.15mm to 0.6mm, where "mm" in this context refers to millimeters. The capillary channel 9392 with smaller inscribed circle diameter has stronger liquid sealing capability and is suitable for application with lower viscosity and smaller liquid output. Capillary passage 9392 with a larger inscribed circle diameter has weaker liquid sealing capability and is suitable for applications with higher viscosity or larger liquid output. In the equilibrium state the capillary channel 9392 is liquid-sealed due to capillary forces.

When the atomizing core 930 works, liquid on the atomizing core 930 is atomized, aerosol escapes out of the aerosol bomb 800 through the aerosol channel 1303, meanwhile, liquid in the liquid storage element 100 is led out through the capillary channel 9392 of the capillary channel relay liquid guide element 939 and is supplemented to the atomizing core 930 or the periphery of the atomizing core 930, when the negative pressure in the liquid storage element 100 rises to a certain degree along with the leading-out of the liquid, the liquid seal of a certain capillary channel 9392 of the capillary channel relay liquid guide element 939 is opened, air in the atomizing chamber 934 enters the liquid storage element 100 through the capillary channel 9392 opened by the liquid seal, so that the negative pressure in the liquid storage element 100 is reduced, the capillary channel 9392 opened by the liquid seal is sealed by the liquid again, and the process is repeated so that the atomizing process can be carried out until the liquid in the liquid storage element 100 is used up.

The structure of this embodiment is similar to that of the first embodiment, and the same parts as the first embodiment are not described again in the description of this embodiment.

As shown in fig. 5a, according to an aerosol 800 with a capillary passage relay liquid guiding element 939 of the fifth embodiment of the present invention, the aerosol 800 includes a liquid storage element 100, an atomizing chamber cavity 9342, an atomizing core 930 and a capillary passage relay liquid guiding element 939, the atomizing core 930 includes an atomizing core liquid guiding element 932, the atomizing core liquid guiding element 932 is communicated with the liquid storage element 100 only through the capillary passage relay liquid guiding element 939, the capillary passage relay liquid guiding element 939 includes a relay liquid guiding element core body 9391 and at least 2 capillary passages 9392 axially penetrating through the relay liquid guiding element core body 9391, the capillary passages 9392 transport liquid from the liquid storage element 100 to the atomizing core liquid guiding element 932 by their capillary force, and the capillary passage relay liquid guiding element 939 has both liquid guiding function and gas guiding function.

The atomizing part in this embodiment includes an atomizing chamber cavity 9342, an atomizing chamber 934, and an atomizing core 930. The atomizing chamber 934 is a cavity in which the liquid is atomized, and is defined by the atomizing chamber cavity 9342 and the housing base 112, and in this embodiment, the atomizing chamber 934 is disposed at the lower portion of the liquid storage component 100. Set up atomizing core 930 in the atomizer 934, be provided with on the casing base 112 and run through casing base through-hole 1122, casing base through-hole 1122 and the one end of external intercommunication are as air inlet 1121, and outside air passes through air inlet 1121 and gets into atomizer 934. The liquid is atomized by atomizing core 930 in atomizing chamber 934 and exits aerosol can 800 through aerosol channel 1303.

As shown in fig. 5b to 5e, in the capillary passage relay liquid guiding element 939 of the present embodiment, only the capillary passage 9392 which is radially closed is provided, that is, the capillary passage 9392 is not radially communicated with the outside except for two ends thereof, and any part of the capillary passage 9392 is not radially communicated with the outside. In this embodiment, the atomizing core wicking element 932 is a cotton fiber bundle. As shown in FIG. 5a, a capillary passage relay liquid guiding element 939 is arranged in the atomizing chamber 934, and the liquid storage element 100 and the atomizing core 930 are directly communicated by the capillary passage relay liquid guiding element 939. Specifically, in this embodiment, two capillary channel relay liquid guiding elements 939 are provided, which are respectively and directly connected to the parts of the atomizing core liquid guiding element 932 near the two ends, and the end opening of the capillary channel 9392 connected to the atomizing core liquid guiding element is blocked by the atomizing core liquid guiding element 932, so that the external air cannot directly enter the capillary channel 9392. The end surface of the capillary passage relay liquid guiding member 939 can be made to compress the two ends of the atomizing core liquid guiding member 932 to ensure the closing of the opening of the end of the capillary passage 9392 by the atomizing core liquid guiding member 932. Capillary channel relay liquid guide element 939 comprises at least 2 axially extending capillary channels 9392, capillary channels 9392 transporting liquid from liquid storage element 100 to atomizing core liquid guide element 932 by virtue of their capillary forces. The liquid guiding member 939 of the present embodiment can be made of plastic such as poly (1-co-1-xylylene terephthalate) (PCTG), poly (ethylene terephthalate-1-co-4-cyclohexanedimethanol) (PETG), or polycarbonate by injection molding or extrusion molding.

In this embodiment, the walls of the capillary channel 9392 can be wetted by the liquid in the liquid storage component 100, and the liquid can move in the capillary channel 9392 under the surface tension of the liquid and the capillary force of the wick liquid-guiding component 932. The capillary channels 9392 in the capillary channel relay liquid guiding element 939 are arranged in a linear or nearly linear shape along the axial direction, which is beneficial to reducing the liquid guiding resistance and reducing the risk of liquid shortage of the atomizing core 930.

After the aerosol bomb 800 is assembled, due to the capillary action of the capillary channel 9392 and the atomizing core liquid guiding element 932, the liquid in the liquid storage element 100 is conducted to the atomizing core liquid guiding element 932 through the capillary channel relay liquid guiding element 939, and as the liquid in the liquid storage element 100 is guided out, a negative pressure difference is formed between the inside of the liquid storage element 100 and the outside. When the negative pressure difference between the inside of the liquid storage component 100 and the outside is high enough, the outside air can enter the liquid storage component 100 through the capillary passage 9392 of the capillary passage relay liquid guide component 939, but since the atomizing core liquid guide component 932 blocks the end opening of the capillary passage 9392 of the capillary passage relay liquid guide component 939 communicated with the atomizing core liquid guide component 932, the outside air cannot directly enter the capillary passage 9392, and the outside air must pass through the atomizing core liquid guide component 932 to enter the capillary passage 9392 of the capillary passage relay liquid guide component 939, and finally enter the liquid storage component 100. The capillary force of the wicking element 932 decreases as the liquid content therein increases until the negative pressure differential with the reservoir element 100 reaches equilibrium with the ambient. The wick element 932 is unsaturated at equilibrium, thus providing further liquid absorption capability and reducing the risk of oil blow-up due to excessive liquid content in the wick element 932 during atomization.

When the liquid in the atomizing core liquid guiding element 932 is consumed by atomization, the capillary force of the atomizing core liquid guiding element 932 is increased, and the atomizing core liquid guiding element 932 performs gas-liquid exchange with the liquid storage element 100 through the capillary channel relay liquid guiding element 939 until the equilibrium state is reached again.

When the ambient temperature rises or the ambient pressure decreases, the air in the liquid storage element 100 expands, the liquid in the liquid storage element 100 is led out, and the unsaturated atomizing core liquid guiding element 932 can absorb the liquid from the liquid storage element 100 through the capillary channel relay liquid guiding element 939, so that the risk of liquid leakage of the aerosol bomb 800 due to the rise of the ambient temperature or the decrease of the ambient pressure is reduced. If the ambient temperature or the ambient air pressure returns to the original state, since the atomizing core liquid guiding element 932 closes the end opening of the capillary channel 9392 of the capillary channel relay liquid guiding element 939 communicated with the atomizing core liquid guiding element 932, so that the external air cannot directly enter the capillary channel 9392, and part of the liquid in the atomizing core liquid guiding element 932 enters the liquid storage element 100 through the capillary channel relay liquid guiding element 939 in preference to the external air. This facilitates the flow of liquid to and from between the reservoir element 100 and the atomizing wick wicking element 932 in the event of a change in ambient temperature or pressure, thereby reducing the risk of liquid leakage during routine use of the aerosol bomb 800.

In this embodiment, the capillary passages 9392 in the capillary passage relay liquid guiding element 939 may be isolated from each other, as shown in fig. 5b and 5 c; the capillary passages 9392 in the capillary passage relay liquid guide member 939 may be communicated with each other, as shown in fig. 5d and 5 e; in the present invention, two capillary channels 9392 are considered to be different capillary channels 9392 if they are communicated with each other, but the two capillary channels 9392 have respective gas or liquid guiding functions.

In summary, the aerosol bomb of the present invention comprises the capillary channel relay liquid guiding element, and the capillary channel is arranged along the axial direction in a linear or nearly linear manner, and the capillary pulling force from the atomizing core liquid guiding element communicated with the capillary channel is added, so that the liquid conveying resistance is small, the speed is high, and the atomizing process can be smoothly performed. When the liquid content in the atomizing core liquid guiding element is increased, the capillary force is reduced, and the negative pressure balance in the liquid storage element conducted through the capillary channel is achieved, so that the liquid content in the atomizing core liquid guiding element is moderate, the atomization is stable, and the risk of oil frying and liquid leakage is reduced. The aerosol bomb has compact structure and can be widely applied to various electronic cigarettes and medicine atomization devices.
