Electronic Cigarette Cartridge to Prevent Leakage of Liquid Substance}

The present invention relates to an electronic cigarette cartridge that prevents leakage of liquid substances, and more specifically, to the inside of a vaporization unit that receives liquid substances from a liquid storage unit and vaporizes them, and that the internal chamber of the vaporization unit is divided into a first chamber and a second chamber. An electronic cigarette cartridge that prevents liquid material from leaking from the first chamber to the second chamber by configuring a partition to divide it into chambers, but allows air necessary for vaporization to flow from the second chamber to the first chamber. It's about.

Cigarette smoke from pipes, leaf pipes, and pipes contains numerous components harmful to the human body, such as tar, hydrocarbons, and carbon monoxide, which cause various diseases such as lung cancer and circulatory diseases, and are not only harmful to the smoker's health, but also to the smoker's health. , The smoke that a smoker exhales when smoking and the harmful ingredients remaining in the place where he smoked cause harm to people around him due to secondhand smoke.

Unlike in the past, various regulations on the sale of smoking cigarettes have been strengthened and policies to reduce smoking rates and encourage smoking cessation, such as limiting smoking places, are being implemented around the world. However, smokers who are addicted to the nicotine component contained in cigarettes are increasing. It is not easy to quit smoking overnight.

In this regard, recently, electronic cigarettes that do not contain harmful ingredients such as tar contained in smoking cigarettes and generate smoke by vaporizing a solution containing nicotine have been developed and are being sold on the market, which reduces the smoker's desire to smoke. Since it emits smoke that is satisfactory and less harmful, it reduces the damage to smokers and second-hand smokers, and is even used as a smoking cessation aid for smokers who want to quit smoking.

FIG. 1 is a view showing a conventional electronic cigarette cartridge 90, and FIG. 2 is a view showing a portion of a side cross-section of FIG. 1, which is disclosed in Korean Patent Publication No. 10-2016-0031801 (2016.03.23). It has been disclosed.

When described with reference to FIG. 1, the conventional electronic cigarette cartridge 90 includes a mouthpiece portion 91 that has a shape that a user can bite into his or her mouth, and a liquid storage portion 93 that stores a liquid substance to be used for vaporization. And, it is configured to include a vaporization portion 95 located inside the liquid storage portion 93 to vaporize the liquid material.

Referring to FIG. 2, the vaporization unit 95 is formed on one side of the vaporization unit 95 so that the liquid material stored in the liquid storage unit 93 can flow into the vaporization unit 95 and be used for vaporization. an inlet hole 951 formed to penetrate, a liquid absorbing part 953 that absorbs the liquid material flowing in from the inlet hole 951, and a liquid absorbing part formed to surround the liquid absorbing part 953. It includes a coil portion 955 that applies heat to the liquid material absorbed in 953 to vaporize it.

A gas inlet 957 through which air necessary for combustion flows is formed on the lower side of the vaporization part 95, and the empty space inside the gas inlet 957 is formed by a ventilation hole 959 formed in the cartridge 90 and As it communicates, the outside air of the cartridge 90 moves to the gas inlet 957 through the ventilation hole 959, and oxygen necessary for combustion is supplied to the inside of the vaporization unit 95.

However, in the conventional electronic cigarette cartridge 90, the liquid absorption portion 953 is immersed in the liquid material and contains the liquid material, so the amount of liquid absorbed is compared to the amount of liquid vaporized by the coil portion 955. If the amount is large, various problems are caused by liquid substances that have not been vaporized.

For example, when an electronic cigarette user sucks vaporized smoke through the mouthpiece 91, the liquid material that has not been vaporized is sucked into the mouth, and the user eats the liquid material or the liquid material gets into the mouth. A problem occurred.

In addition, as the liquid material excessively absorbed in the liquid absorption unit 953 accumulates, it falls due to gravity, and as the falling liquid materials gather and escape through the ventilation hole 959, etc., the liquid material spreads around the electronic cigarette. There was a leaking problem.

Recently, efforts have been made to make the material of the liquid absorbing part 953, made of cotton, etc., of higher quality in order to prevent the leakage of such liquid substances. However, for vaporization, the liquid absorbing part 953 is made of liquid substances. Since it had the property of absorbing water, there were limitations in solving the water leakage problem caused by excessively absorbed liquid substances.

Accordingly, the related industry is requesting the development of a new type of electronic cigarette cartridge that solves the problem of liquid material leakage caused by the liquid material overflowing into the liquid absorption unit 953.

Figure 3 is a diagram showing an electronic cigarette cartridge (1) according to an embodiment of the present invention. When explained with reference to Figure 3, the present invention is an electronic cigarette cartridge (1) that prevents leakage of liquid substance (L). Regarding this, a partition 17, which will be described later, is formed inside the vaporization unit 10 to prevent the liquid material (L) from passing through the partition 17 by using the surface tension or viscosity of the liquid material (L). By doing so, external leakage of the liquid substance (L) is prevented, but the air required for vaporization is allowed to flow into the vaporization unit (10) from the outside. As shown in FIG. 3, this electronic cigarette cartridge 1 includes a vaporizing unit 10, a liquid storage unit 30, and a mouthpiece unit 50.

The vaporization unit 10 refers to a configuration that receives a liquid substance (L) from the liquid storage unit 30, which will be described later, and applies heat to the supplied liquid substance (L) to vaporize it from a liquid to a gas. Specifically, the vaporizing unit 10 receives electrical energy, radiates heat through the supplied electrical energy, and vaporizes the liquid substance (L) absorbed by the radiated heat to generate smoke.

FIG. 4 is a cross-sectional view taken along line A-A' of FIG. 3, and when explained with reference to FIG. 4, the vaporization unit 10 includes a housing unit 11, a liquid absorption unit 13, a coil unit 15, and a partition unit ( 17), including the current carrying part (19).

The housing portion 11 is a configuration that forms the outer shape of the vaporization portion 10, and as shown in FIG. 4, it may have a cylindrical shape with the upper and lower surfaces open while forming an empty space on the inside. . The housing portion 11 includes an inner chamber 111 and an inlet hole 113.

The inner chamber 111 refers to an empty space formed inside the housing portion 11, and the inner chamber 111 is divided into a first chamber 1111 and a second chamber by a partition portion 17 to be described later. It can be separated and classified as (1113). The first chamber 1111 refers to an empty space located above the partition 17, which will be described later, and the second chamber 1113 refers to an empty space located below the partition 17, which will be described later. Liquid material (L) required for vaporization flows into the first chamber 1111, but the inflow of liquid material (L) may be blocked in the second chamber 1113 by a partition 17, which will be described later.

The inlet hole 113 is formed to penetrate from one side of the housing portion 11 to the other side so that the liquid material (L) stored in the liquid storage portion 30, which will be described later, can flow into the first chamber 1111. The formed hole is formed on the upper side of the partition 17, which will be described later, and communicates with the first chamber 1111. Preferably, a liquid absorbing part 13, which will be described later, is located on the inner surface of the inlet hole 113, and the liquid substance (L) flows into the first chamber 1111 through the inlet hole 113. ) is absorbed in the liquid absorption unit 13, which will be described later. The shape of the inlet hole 113 is not limited to any specific shape, but preferably has a circular shape, and a plurality of inlet holes 113 may be formed on the side of the housing portion 11, and these plurality of inflow holes 113 may have a circular shape. Among the holes 113, the inflow holes 113 may be formed at opposing positions to form a pair.

The liquid absorbing part 13 is located in the first chamber 1111 and is formed to cover the inner surface of the inlet hole 113, so that the liquid substance (L) flowing in through the inlet hole 113 refers to a composition that absorbs. The coil portion 15, which will be described later, is formed to wrap around the liquid absorbing portion 13 and vaporizes the liquid substance (L) absorbed by the liquid absorbing portion 13. The material of the liquid absorbing part 13 is not limited to any specific material, but may preferably be made of cotton, activated carbon, etc. The liquid absorbing part 13 may be formed in a shape that connects opposing inflow holes 113, through which the liquid substance (L) flows in from both sides of the liquid absorbing part 13.

The coil portion 15 is formed to surround the liquid absorbing portion 13, and is configured to radiate heat by receiving current from an energizing portion 19, which will be described later. The heat emitted by the coil unit 15 heats the liquid substance (L) absorbed by the liquid absorption unit 13 to generate gas, and the generated gas is transmitted through the mouthpiece unit 50, which will be described later. It can be inhaled through the user's mouth. The coil part 15 may extend from the first chamber 1111 to the second chamber 1113 through a through hole 1711 formed in the partition part 17, which will be described later, and through this, the second chamber 1113 It can be connected to the energizing part 19 formed at 1113.

Figure 5 is a diagram showing the partition unit 17 according to an embodiment of the present invention, and Figure 6 is a cross-sectional view taken along line B-B' of Figure 5. Hereinafter, Figures 5 and 6 will be referred to.

The partition part 17 is located below the liquid absorbing part 13 and separates the inside of the housing part 11 forming the internal chamber 111 to prevent leakage of the liquid material (L). It refers to the composition of division. Preferably, the partition portion 17 may be formed in a plate-like shape to separate the inner chamber 111 into a first chamber 1111 located on the upper side and a second chamber 1113 located on the lower side. . More preferably, the partition portion 17 is spaced apart from the liquid absorbing portion 15 to prevent the liquid material (L) falling from the liquid absorbing portion 15 from flowing into the second chamber 1113. It may have a shape that allows the gas required for vaporization to pass from the second chamber 1113 to the first chamber 1111 while blocking it from doing so.

As a result, the liquid absorption unit 15 is located in the first chamber 1111 located on the upper side with respect to the partition unit 17, and the liquid absorption unit 15 is located in the first chamber 1111 located on the upper side with respect to the partition unit 17. Even if the liquid that overflows into the liquid absorption unit 15 fails to vaporize and collects and falls due to gravity, the second chamber 1113 is maintained by the partition unit 17 located on the lower side of the liquid absorption unit 15. It is possible to prevent liquid material (L) from flowing into the side.

The material of the partition 17 is not limited to any specific material, but a through hole 1711 and an extension hole 1731, which will be described later, are formed on the partition 17 to form a through hole 1711 and an extension hole. Since the coil portion 15 passes through (1731), the partition portion 17 is made of plastic that does not conduct electricity so that the current flowing through the coil portion 15 is not lost by the partition portion 17. It may be desirable to construct it with an insulator such as the like.

This partition portion 17 includes a body portion 171 and an extension portion 173.

The body portion 171 is a part of the partition portion 17 that forms a plate-shaped body, and may preferably be configured in a disk shape as shown in FIG. 5. The body portion 171 allows the inner chamber 111 of the housing portion 11 to be separated into the first chamber 1111 and the second chamber 1113, and thus the second chamber 1113 ) can prevent liquid substances from entering the system.

Referring to FIG. 5, the body portion 171 includes a through hole 1711 and an attachment surface 1713.

The through hole 1711 is a hole formed to penetrate from one side of the body portion 171 to the other side. The through hole 1711 allows liquid to flow from the first chamber 1111 to the second chamber 1113. The liquid material (L) is prevented from moving by the surface tension of the liquid material (L) so that the air required for vaporization can flow from the second chamber (1113) to the first chamber (1111). (L) may be formed to a size that does not pass through the through hole (1711), or may be formed to a size that does not allow the liquid material (L) to pass through the through hole (1711) due to the viscosity of the liquid material (L). You can. Referring to FIG. 6, the through hole 1711 may be configured so that the size of the upper opening (W1) is the same as the size of the lower opening (W2) (W1 = W2), as shown in FIG. 6.

The attachment surface 1713 is a surface to which the liquid material (L) is attached and serves to provide surface tension of the droplet. Surface tension refers to the property of the force that causes the surface of a liquid to contract itself and take up as small an area as possible, and is a type of interfacial tension. Figure 7 is a conceptual diagram to explain this surface tension. Referring to Figure 7, while the molecules (M) existing inside the liquid material (L) receive force isotropically from the surrounding molecules (M), Since the molecules (M) located on the surface do not have a force acting from the outside of the liquid material (L), they receive a force in the inner direction of the liquid material (L). In other words, the molecules on the surface have a greater free energy than the molecules on the inside, so the liquid substance (L) tends to have a small surface area, which generates surface tension. For example, when two water droplets of the same size meet, they immediately merge into one water droplet. This is because the surface area when they exist as one combined sphere is much smaller than the sum of the surface areas when they exist as two independent spheres.

When the capillary is placed in a water tank storing the liquid material (L) as shown in Figure 8, the self-weight of the liquid material (L) flowing into the capillary (

If the air pressure difference between the inside and outside of the droplet is P, and the radius of the droplet is d, then the resultant force acting on the circumference of the cut surface of the droplet due to surface tension and the force generated by the pressure difference are in balance, so these The relationship can be expressed as follows.

FIG. 10 is a diagram showing the liquid substance (L) blocking the through hole 1711 by surface tension. When explained with reference to FIG. 10, the liquid substance (L) overflowing into the liquid absorption unit 13 If the remaining liquid material (L) is not vaporized and gradually accumulates, the non-vaporized liquid material (L) may fall on the upper side of the partition 17 while forming droplets. At this time, the above-described through-hole 1711 is formed on the partition 17. The size of this through-hole 1711 is such that the liquid substance (L) does not pass through the through-hole 1711 due to the above-mentioned surface tension. If the liquid material (L) is formed to an unreasonable size, the liquid material (L) cannot pass through the through hole (1711) due to surface tension, preventing the liquid material (L) from flowing into the second chamber (1113). As a result, it is possible to prevent leakage of the liquid substance (L).

)이 발생될 수 없어, 액적이 상기 관통홀(1711)을 통해 상기 제2챔버(1113) 측으로 유출되기 때문이다. 이로 인해 부착면(1713) 형성이 어려운 메쉬망으로 상기 파티션부(171)를 형성하는 것은 바람직하지 않을 수 있다.What is important at this time is the surface tension that prevents the droplet from passing through the through hole 1711, as shown in Figure 10.

) is that an attachment surface 1713 must be formed around the through hole 1711 so that the. If the attachment surface 1713 is not present, the surface tension acting in the opposite direction to the force of gravity (

) cannot be generated, and the droplets flow out toward the second chamber 1113 through the through hole 1711. For this reason, it may not be desirable to form the partition portion 171 with a mesh network on which it is difficult to form an attachment surface 1713.

FIG. 11 is a diagram showing a plurality of through holes 1711 in which the attachment surface 1713 does not overlap. Referring to FIG. 11, it is necessary to prevent liquid droplets from flowing out through the through holes 1711 shown in FIG. 11. In order to do this, if an attachment surface 1713 as shown in FIG. 11 is to be formed around each through hole 1711, no overlap should occur between the attachment surfaces 1713 around different through holes 1711. .

)이 발생하지 않게 되면서, 액적이 상기 관통홀(1711)을 통해 상기 제2챔버(1113) 측으로 유출될 수밖에 없다.If overlap between the attachment surfaces 1713 occurs as shown in FIG. 12, surface tension (which will cancel out the force in the direction of gravity)

) does not occur, the droplets have no choice but to flow out toward the second chamber 1113 through the through hole 1711.

Therefore, when constructing the through hole 1711 on the body portion 171, the gap between the through holes 1711 must be adjusted to prevent overlap between the attachment surfaces 1713 surrounding the through hole 1711. It is necessary to adjust the size of the through hole 1711 and the size of the attachment surface 1713 to prevent the liquid substance (L) from escaping through the through hole 1711.

Similar to preventing leakage of the liquid material (L) using surface tension, the present invention can also prevent leakage of the liquid material (L) by using the inherent viscosity of the liquid material (L). Viscosity refers to the resistance to the flow of fluid, and is also called internal friction because it is the frictional force that appears inside a moving liquid or gas. Viscosity, like friction, converts the kinetic energy of a moving object into heat energy. Viscosity represents the degree of viscosity of a fluid, and is a physical unit that represents the degree of stickiness of the fluid, and is expressed as the ratio of shear stress and shear rate.

When the through hole 1711 is formed to a size that prevents the liquid material (L) from passing through the through hole 1711 due to the viscosity of the liquid material (L), the liquid material (L) cannot pass through the through hole (1711). Unless a pressure greater than the viscosity of the liquid material (L) that allows it to pass through (1711) is applied, the liquid material (L) cannot pass through the through hole (1711), and eventually the liquid material (L) ) can prevent external leakage.

Furthermore, considering both the surface tension and viscosity of the liquid material (L) for the size of the through hole (1711), the liquid material (L) is formed through the through hole ( 1711), it is possible to prevent the liquid material (L) from leaking into the second chamber 1113.

In addition, by forming the through hole 1711, the air required for vaporization can be supplied from the second chamber 1113 to the first chamber 1111 through the through hole 1711, and the liquid phase is absorbed. The coil part 15 wound around the part 15 passes through the partition part 17 through the through hole 1711 and forms an energizing part 19, which will be described later, located on the lower side of the second chamber 1113. As a result, the coil unit 15 can receive current from the energizing unit 19 and dissipate heat.

Even if the droplets of the liquid substance (L) collected on the upper side of the partition unit 17 close the through hole 1711 due to surface tension and/or viscosity, the mouthpiece unit 50, which will be described later, will be removed by the user during use of the electronic cigarette. When the liquid is sucked in the mouth, the liquid droplets located on the upper side of the partition unit 17 may be sucked up and reabsorbed into the liquid absorption unit 15.

As described above, a plurality of through holes 1711 may be formed on the body portion 171 of the partition 17, and some of the through holes 1711 formed on the body portion 171 may be Even if it is blocked by the liquid substance (L), the air required for vaporization can move to the first chamber (1111) through another through hole (1711), and the through hole (1711) is blocked during the user's smoke inhalation process. The liquid substance (L) is absorbed into the liquid absorption part 15 by its suction force, thereby opening the through hole 1711 that was closed by the liquid substance (L).

In FIG. 6 discussed above, the through hole 1711 is configured so that the size of the upper opening (W1) and the size of the lower opening (W2) are the same, but the shape of the through hole 1711 is not necessarily limited to this shape. no. Preferably, as shown in FIG. 13, the size of the upper opening (W1) may be smaller than the size of the lower opening (W2) (W1<W2), and the size of the upper opening of the through hole 1711 is , the liquid material (L) may be formed to a size that does not pass through the upper opening of the through hole (1711) due to the surface tension and/or viscosity of the liquid material (L).

When the through hole 1711 is configured as shown in FIG. 13, the size of the upper opening (W1) can be relatively reduced, and the value of r becomes smaller in the formula below,

The surface tension can be further increased. Additionally, as the size of the upper opening (W1) becomes smaller, the influence of viscosity also increases. Ultimately, when the partition 17 is configured in this way, a greater external force is required for the liquid material (L) to pass through the through hole 1711, and external leakage of the liquid material (L) is more reliably blocked. It can be.

In addition, as the size (W2) of the lower opening becomes wider, when air moves from the second chamber 1113 to the first chamber 1111, the flow speed increases due to Bernoulli's theorem, which causes the through hole ( 1711) can be easily removed, and the liquid material (L) separated from the surface of the partition 17 can be easily reabsorbed into the liquid absorption unit 13 as it rises. .

Figure 14 is a diagram showing the partition unit 17 according to another embodiment of the present invention, and will be described below with reference to Figure 14.

The extension portion 173 refers to a configuration in which the peripheral body portion 171 of the through hole 1711 is extended in the direction of the first chamber 1111, as shown in FIG. 14. The extension portion 173 may be formed in a cylindrical shape with one side and the other side open while forming an extension hole 1731, which is an empty space on the inside. This extension 173 includes an extension hole 1731 and an attachment surface 1733.

The extension hole 1731 may be formed so that the size of the upper opening (W1) is smaller than the size of the lower opening (W2) (W1<W2). As a result, the effect of preventing the liquid material (L) from flowing into the second chamber 1113 through the relatively small upper opening of the extension hole 1731 is increased, and the lower side of the relatively large extension hole 1731 is increased. The air required for combustion is allowed to flow more easily into the first chamber 1111 through the opening. Preferably, the upper opening of the extension hole 1731 is formed to a size that prevents the liquid material (L) from passing through the upper opening of the extension hole (1731) due to the surface tension of the liquid material (L). Due to the viscosity of the liquid material (L), the liquid material (L) may be formed to a size that does not pass through the upper opening of the extension hole (1731).

Preferably, the extension hole 1731 may be formed such that the size of the horizontal cross-sectional opening decreases from the lower opening to the upper opening. Through this, a relatively narrow upper opening is formed and a greater pressure must be applied to allow the liquid material (L) to pass through the partition 17, thereby ensuring more prevention of leakage of the liquid material (L) and combustion. As the air required moves from the relatively wide lower opening to the relatively narrow upper opening, the flow rate increases, making it possible to more easily remove the liquid substance (L) blocking the upper opening.

The attachment surface 1733 is a surface to which liquid droplets are attached, and even when the extension portion 173 is formed to form a surface tension that prevents the outflow of the liquid material (L) through the extension hole 1731, the above-mentioned The attachment surface 1733 of the extension portion 173 must be formed corresponding to the attachment surface 1713 of the body portion 171. When the same extension hole 1731 as shown in FIG. 15 is formed, but the extension part 173 is not configured in an inclined shape and is formed to extend vertically as shown in FIG. 16, the extension part 173 There is an advantage that the attachment surface 1733 of (173) can be secured to a large extent. However, an excessive increase in the attachment surface 1733 causes an unnecessary increase in the volume of the extension part 173, which may cause problems such as waste of material and an increase in the weight of the partition part 17. Therefore, the extension portion 173 is designed by considering both the side for securing the attachment surface 1733 necessary to form the surface tension that prevents leakage of the liquid material (L) and the side for preventing unnecessary weight increase, etc. It is desirable to determine the shape.

FIG. 17 is a view showing another embodiment of FIG. 15. As shown in FIG. 13, the through hole 1711 may be configured to decrease in size from the lower opening W2 to the upper opening, The extension hole 1731 also has a lower opening that is the same as the upper opening of the through hole 1711, and as shown in FIG. 17, the upper opening of the extension hole 1731 extends from the lower opening of the extension hole 1731 ( It can also be configured to decrease in size as it goes to W1).

The current conducting unit 19 is connected to the coil unit 15 of the vaporizing unit 10 and supplies current to the coil unit 15. The energizing part 19 is connected to a battery, etc. to receive electric energy, and transfers the supplied electric energy to the coil part 15 to radiate heat from the coil part 15, and this heat causes the nose to radiate. As the liquid absorbing part 13 wrapped around the part 15 receives heat, the liquid substance L absorbed by the liquid absorbing part 13 can be vaporized.

The liquid storage unit 30 is a configuration that stores a liquid substance (L) and supplies the liquid substance (L) to the vaporization unit 10. Preferably, the liquid storage unit 30 is configured to include the vaporization unit 10 inside, as shown in FIG. 4. Even if no special measures are taken, the liquid stored in the liquid storage unit 30 The substance (L) can naturally flow into the vaporization unit (10).

The mouthpiece part 50 is formed in a shape that an electronic cigarette user can bite into, and a gas pipe through which vaporized smoke moves can be formed inside, and this gas pipe has one side of the electronic cigarette cartridge (1). ) is in communication with the outside, and the other side is in communication with the vaporization unit 10 so that the smoke generated in the vaporization unit 10 can escape to the outside through the gas pipe.

Figure 18 is a diagram showing the state of use of the present invention. Referring to Figure 18, the electronic cigarette cartridge 1, which prevents leakage of liquid material according to the present invention, prevents leakage of liquid material even if liquid material L is excessively introduced into the liquid absorption portion 13. , when the liquid material L that has not been vaporized falls due to gravity, the partition 17 blocks the inflow into the second chamber 1113.

However, a through hole 1711 must be formed in the partition 17 so that the air required for vaporization can flow into the first chamber 1111, and the size of this through hole 1711 is the size of the liquid material (L). Due to the surface tension and viscosity of ), the liquid material (L) is formed to a size that does not pass through the through hole 1711, preventing leakage of the liquid material (L) and allowing external air to pass through the through hole 1711. can be allowed to flow into the first chamber 1111.

Even if the through hole 1711 is blocked by the surface tension and/or viscosity of the liquid material (L), the user holds the mouthpiece portion 50 of the electronic cigarette cartridge 1 in his mouth and inhales to suck in smoke. When doing this, air flows quickly from the bottom to the top, lifting the liquid droplets covering the through hole 1711, and these droplets are reabsorbed in the liquid absorption unit 13 located at the top, thereby removing the oxygen necessary for combustion. While enabling the supply of , it is possible to promote reuse of the liquid material (L) that has not been vaporized.

In addition, the coil part 15 surrounding the liquid absorbing part 13 can be connected to the energizing part 19 through the through hole 1711, so even if the partition part 17 is formed, the energizing part ( Heat is dissipated by the current moving from 19) to the coil unit 15.
