Description

an aerosol bomb technical field

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

Background technique

The technology of atomizing liquid has been widely used in fields such as electronic cigarettes. A common technology in electronic vaping is to heat the liquid-guiding element of the atomizing core that is directly connected to the e-liquid, such as glass fiber bundles or cotton fiber bundles passing through the cavity of the atomization chamber, to atomize the liquid. It is necessary to properly match the atomizing chamber cavity and the atomizing core liquid-conducting element, so that the liquid can be conducted from the atomizing core liquid-guiding element while allowing the outside air to pass through the gap between the atomizing core liquid-guiding element and the atomizing chamber cavity. into the reservoir element. Because the glass fiber bundle and cotton fiber bundle are soft and lack a fixed shape, it is difficult to precisely control the gap between the liquid-guiding element of the atomizing core and the cavity of the atomizing chamber. The oil will explode during the atomization, and the liquid will leak in severe cases. If the gap is too small, it is difficult for the air to enter the liquid storage element, which will lead to the lack of liquid in the atomization core and the paste core, which will affect the stability of the atomization and the consumption experience.

According to a known aerosol bomb with a gas-liquid channel, the gas-liquid channel includes a fluid core made of fiber bonding, the fluid core is used to conduct liquid for the atomizing core, and the fluid core is used to absorb the liquid and release to control the liquid sealing of the gas-liquid channel to control the atomization process. For example, in an equilibrium state, the fluid core absorbs enough liquid, and the liquid on the peripheral surface of the fluid core seals the gas-liquid channel. When the liquid is led out from the liquid storage element, the negative pressure in the liquid storage element increases, the liquid in the gas-liquid channel is absorbed by the fluid core, part or all of the liquid seal of the gas-liquid channel disappears, and the air in the atomizing chamber passes through the gas-liquid channel Entering the liquid storage element, when the vacuum degree in the liquid storage element is reduced to an equilibrium state, the gas-liquid channel is re-sealed by the liquid. In this technology, the liquid flow path in the fiber-bonded fluid core is tortuous and the liquid flow speed is slow, especially when the temperature is low, the viscosity of the electronic cigarette liquid whose main components are propylene glycol and glycerin is high, which is easy to cause fogging. Insufficient liquid supply to the core will affect the taste or even paste the core.

<Capillary channel relay liquid guide element>

In this embodiment, as shown in FIG. 1a , the capillary channel relay liquid guide element 939 is disposed in the atomization chamber 934 , and the liquid storage element 100 and the atomization core 930 are communicated by the capillary channel relay liquid guide element 939 . As shown in FIG. 1b to FIG. 1h, the capillary channel relay liquid guiding element 939 includes at least two axially penetrating capillary channels 9392, and the capillary channel 9392 uses its capillary force to transport the liquid from the liquid storage element 100 to the atomizing core liquid guiding element 932.

In the present invention, the wall 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. The inner peripheral wall is processed, or the inner peripheral wall of the capillary channel 9392 is coated or added with a hydrophilic material, so that the inner peripheral wall of the capillary channel 9392 can be wetted by liquid.

Under the action of the surface tension of the liquid and the capillary force of the liquid-conducting element 932 of the atomizing core, the liquid can flow in the capillary channel 9392. The capillary channels 9392 in the capillary channel relaying liquid-conducting element 939 are arranged in a linear or almost straight line along the axial direction, that is, the capillary channel 9392 in the capillary channel relaying the liquid-conducting element 939 and the capillary channel relaying the liquid-conducting element 939 are arranged. The axial direction is parallel or substantially parallel, so that the liquid can flow in the axial direction in the capillary channel 9392 , and this structure is beneficial to reduce the resistance of liquid conduction and reduce the risk of liquid shortage of the atomizing core 930 .

The capillary channel relay liquid guiding element 939 may include radially closed capillary channels 9392 or peripherally closed capillary channels 9392, as shown in FIG. 1b, FIG. 1c, and FIG. 1d. The capillary channel relay liquid-conducting element 939 may also include radially open capillary channels 9392 or capillary channels 9392 open at the periphery, as shown in FIG. 1e, FIG. 1f, and FIG. 1g. The capillary channel relay liquid-guiding element 939 can also include both radially closed capillary channels 9392 and radially open capillary channels 9392, as shown in FIG. 1h. A relay liquid guide element outer tube 9393 can be set outside the radially open capillary channel relay liquid guide element 939, and the length of the relay liquid guide element outer tube 9393 is equal to the capillary channel relay liquid guide element 939, so that the radially open The capillary channel relay liquid guide element 939 becomes a radially closed capillary channel relay liquid guide element 939, as shown in Figure 1i. The length of the outer tube 9393 of the relay liquid guiding element can also be made smaller than the capillary channel relay liquid guiding element 939, so that a part of the radially open capillary channel 9392 becomes radially closed, as shown in FIG. 1j. The capillary channel relay liquid-conducting element 939 can be formed by techniques such as injection molding or extrusion using plastic or metal. Except for the capillary channel 9392 which can conduct fluid, the other parts of the capillary channel relay fluid conducting element 939 have no fluid conducting function.

The capillary channel relay liquid guiding element 939 can directly communicate with the liquid storage element 100 and the atomizing core liquid guiding element 932, and the connection method is simple. It is also possible to set a relay buffer liquid storage part 938 in the atomization chamber 934, so that the capillary channel relay liquid guide element 939 communicates with the atomization core liquid guide element 932 through the relay buffer liquid storage part 938. The buffer liquid storage part 938 plays a function of temporarily storing liquid, and in the case of a large amount of atomization in a short time, the risk of liquid shortage of the atomizing core 930 can be reduced. When encountering abnormal conditions, such as external negative pressure, the relay buffer liquid storage part 938 can absorb a small amount of liquid leaking from the liquid storage element 100 , thereby preventing the liquid from leaking from the aerosol bomb 800 .

The size of the capillary channel 9392 in the capillary channel relay liquid guiding element 939 is represented by the maximum inscribed circle diameter of the smallest cross section in the capillary channel 9392, and the size of different capillary channels 9392 in the capillary channel relay liquid guiding element 939 can be the same or different. . The maximum inscribed circle diameter of the smallest cross-section in the capillary channel 9392 is 0.1 mm to 0.8 mm, such as 0.1 mm, 0.15 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.8 mm, preferably 0.15 mm to 0.6 mm mm, "mm" in this document all refers to millimeters. The capillary channel 9392 with smaller inscribed circle diameter has strong liquid sealing ability and is suitable for applications with low viscosity and small liquid output. The capillary channel 9392 with a larger inscribed circle diameter has a weaker liquid sealing ability and is suitable for applications with high viscosity or large liquid output. In the equilibrium state the capillary channel 9392 is liquid-sealed due to capillary force.

When the atomizing core 930 is working, the liquid on the atomizing core 930 is atomized, the aerosol escapes the aerosol bomb 800 through the aerosol channel 1303, and the liquid in the liquid storage element 100 relays the flow of the liquid guide element 939 through the capillary channel. The capillary channel 9392 is led out and supplemented to the atomizing core 930 or its periphery. As the liquid is led out, when the negative pressure in the liquid storage element 100 rises to a certain level, the capillary channel relays a certain capillary channel 9392 of the liquid conducting element 939. The air in the atomization 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, and the capillary channel 9392 opened by the liquid seal is re-sealed by the liquid seal. , this process is repeated so that the atomization process can continue until the liquid in the liquid storage element 100 is used up.

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, As the liquid in the liquid storage element 100 is led out, a negative pressure difference is formed inside the liquid storage element 100 and the outside. When the negative pressure difference between the liquid storage element 100 and the outside world is high enough, the outside air can enter the liquid storage element 100 through the capillary channel 9392 of the capillary channel relay liquid-conducting element 939. The end of the capillary channel 9392 of the connected capillary channel relay liquid-conducting element 939 is open, so that the outside air cannot directly enter the capillary channel 9392, and the outside air must pass through the atomizing core liquid-conducting element 932 to enter the capillary channel relay.

The liquid element 939 absorbs liquid from the liquid storage element 100, thereby reducing the risk of liquid leakage from the aerosol bomb 800 due to an increase in ambient temperature or a decrease in external pressure. If the ambient temperature or the external air pressure returns to the original state, the end opening of the capillary channel 9392 of the capillary channel relay liquid-conducting element 939 is blocked by the atomizing core liquid-conducting element 932, so that the outside air cannot directly enter the Referring to the capillary channel 9392, part of the liquid in the atomizing core liquid-conducting element 932 enters the liquid storage element 100 through the capillary channel relaying the liquid-conducting element 939 prior to the outside air.
