Description

E-cigarette cartridges that prevent leakage of liquid substances

The present invention relates to an electronic cigarette cartridge that prevents liquid material from leaking, and more particularly, to a vaporizing unit that receives liquid material from a liquid storage unit and vaporizes it. By constructing a partition unit dividing the electronic cigarette cartridge into chambers, the liquid material is prevented from leaking from the first chamber to the second chamber, but air required for vaporization is introduced from the second chamber to the first chamber. It is about.

Cigarette smoke, such as cigarette smoke, tobacco smoke, and pipe tobacco, contains countless components harmful to the human body, such as tar, hydrocarbons, and carbon monoxide, which cause various diseases such as lung cancer and circulatory disease, and not only smokers' health. In addition, second-hand smoke causes harm to people around them due to the cigarette smoke exhaled when smokers smoke and the harmful components remaining in the place where they smoke.

Unlike in the past, various regulations on the sale of smoked cigarettes have been strengthened and policies to reduce smoking rates and encourage smoking cessation, such as restricting smoking places, are being implemented worldwide, but smokers addicted to nicotine contained in cigarettes Quitting smoking overnight is not an easy task.

In this regard, recently, an electronic cigarette that does not contain harmful components such as tar contained in smoking cigarettes and generates smoke by vaporizing a solution containing nicotine has been developed and marketed. Since it emits smoke that can satisfy but is less harmful, it reduces damage to smokers and secondhand smokers, and is even used as a smoking cessation aid for smokers who want to quit smoking.

Referring to FIG. 1, the conventional electronic cigarette cartridge 90 includes a mouthpiece part 91 having a shape that a user can bite into, and a liquid storage part 93 for storing liquid material to be used for vaporization. And, it is configured to include a vaporization unit 95 located inside the liquid storage unit 93 to vaporize the liquid material.

Referring to FIG. 2, the vaporization unit 95 is mounted on one surface of the vaporization unit 95 so that the liquid material stored in the liquid storage unit 93 flows into the vaporization unit 95 and is used for vaporization. An inlet hole 951 formed to pass through the inlet hole 951, a liquid absorbing part 953 absorbing the liquid material introduced from the inlet hole 951, and formed to surround the periphery of the liquid absorbing part 953 to form the liquid absorbing part. It includes a coil unit 955 that vaporizes the liquid material absorbed by the 953 by applying heat to it.

A gas inlet 957 through which air necessary for combustion is introduced is formed at the lower side of the evaporator 95, and the empty space inside the gas inlet 957 is formed through a ventilation hole 959 formed in the cartridge 90 and As the communication bar, the outside air of the cartridge 90 moves to the gas inlet 957 through the ventilation hole 959, and oxygen required for combustion is supplied to the inside of the vaporization unit 95.

However, in the conventional electronic cigarette cartridge 90, since the liquid absorbing part 953 is immersed in the liquid material and holds the liquid material, the liquid material absorbed compared to the amount of liquid vaporized by the coil part 955. When the amount of is large, various problems caused by liquid substances that have not been vaporized.

For example, when the user of the electronic cigarette sucks the vaporized smoke through the mouthpiece part 91, the non-vaporized liquid material is sucked into the mouth, so that 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 absorber 953 accumulates, it falls due to gravity, and as the fallen liquid material gathers and escapes through the ventilation hole 959, etc., the liquid material spreads around the electronic cigarette. There was a leak problem.

Recently, efforts have been made to make the material of the liquid absorber 953 made of cotton or the like into a higher quality material in order to prevent leakage of the liquid material, but the liquid absorber 953 is used to vaporize the liquid material. However, there is a limit to solving the leakage problem caused by the excessively absorbed liquid substance.

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

3 is a view showing an electronic cigarette cartridge 1 according to an embodiment of the present invention. Referring to FIG. 3, the present invention is an electronic cigarette cartridge 1 that prevents leakage of liquid material (L). Regarding, by configuring a partition unit 17 to be described later inside the vaporization unit 10, using the surface tension or viscosity of the liquid material (L) to prevent the liquid material (L) from passing through the partition unit (17). By doing so, the external leakage of the liquid material (L) is prevented, but the air required for vaporization has a feature that allows it to be introduced into the vaporizing unit (10) from the outside. As shown in FIG. 3, such an electronic cigarette cartridge 1 includes a vaporization unit 10, a liquid storage unit 30, and a mouthpiece unit 50.

The vaporization unit 10 refers to a configuration in which liquid material L is supplied from a liquid storage unit 30 to be described later, and heat is applied to the supplied liquid material L to vaporize it from a liquid to a gas. Specifically, the vaporizing unit 10 receives electrical energy, emits heat through the supplied electrical energy, and vaporizes the liquid material L absorbed by the dissipated heat to generate smoke.

4 is a cross-sectional view taken along line A-A' of FIG. 3. Referring to FIG. 4, the vaporizing unit 10 includes a housing unit 11, a liquid absorption unit 13, a coil unit 15, a partition unit ( 17), and a conductive part 19.

The housing part 11 is configured to form the outer shape of the vaporizing part 10, and as shown in FIG. 4, it may have a cylindrical shape with upper and lower surfaces open while forming an empty space inside. . The housing part 11 includes an inner chamber 111 and an inlet hole 113.

The inner chamber 111 refers to an empty space formed inside the housing part 11, and the inner chamber 111 is divided into a first chamber 1111 and a second chamber by a partition part 17 to be described later. (1113) can be separated. The first chamber 1111 refers to an empty space located above the partition unit 17 to be described later, and the second chamber 1113 refers to an empty space located below the partition unit 17 to be described later. In the first chamber 1111, the liquid material (L) necessary for vaporization is introduced, but the second chamber 1113 may be blocked from the liquid material (L) by the partition unit 17 to be described later.

The inlet hole 113 passes through one surface of the housing part 11 to the other surface so that the liquid material L stored in the liquid storage part 30, which will be described later, can be introduced into the first chamber 1111. As a formed hole, it is formed on the upper side of the partition part 17 to be described later and communicates with the first chamber 1111. Preferably, a liquid phase absorbing portion 13 to be described later is located on the inner surface of the inlet hole 113, and the liquid material introduced into the first chamber 1111 through the inlet hole 113 (L ) is absorbed by the liquid absorption unit 13 to be described later. Although the shape of the inlet hole 113 is not limited to any specific shape, it may preferably have a circular shape, and a plurality of inlets may be formed on the side surface of the housing part 11, and the inlet hole 113 may have a plurality of inlets. Among the holes 113, the inlet holes 113 may be formed in pairs by being formed on positions facing each other.

The liquid phase absorbing part 13 is located in the first chamber 1111 and is formed to cover the inner surface of the inlet hole 113, and the liquid material L introduced through the inlet hole 113 refers to a composition that absorbs The coil part 15 to be described later is formed to wind around the liquid phase absorbing part 13 and vaporizes the liquid material L absorbed by the liquid phase absorbing part 13 . The material of the liquid absorbing part 13 is not limited to any particular material, but may be preferably made of cotton, activated carbon, or the like. The liquid phase absorbing part 13 may be formed in a shape connecting inlet holes 113 facing each other, through which liquid material L is introduced from both sides of the liquid absorbing part 13 .

The coil part 15 is formed to surround the liquid phase absorbing part 13, and refers to a configuration in which heat is dissipated by receiving a current from a conducting part 19 to be described later. The heat dissipated by the coil part 15 heats the liquid material L absorbed by the liquid phase absorbing part 13 to generate gas, and the generated gas passes through the mouthpiece part 50 to be described later. It can be inhaled into 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 a partition part 17 to be described later, and through this, the second chamber It can be connected to the conducting part 19 formed at 1113.

FIG. 5 is a diagram showing a partition unit 17 according to an embodiment of the present invention, and FIG. 6 is a BB′ cross-sectional view of FIG. 5. Reference will be made to FIGS. 5 and 6 hereinafter.

The partition part 17 is located below the liquid phase absorbing part 13 to separate the inside of the housing part 11 forming the inner chamber 111 to prevent leakage of the liquid material (L). refers to the composition of the partition. Preferably, the partition unit 17 may be formed in a plate-like shape that separates 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 part 17 is spaced apart from the liquid phase absorbing part 15 so that the liquid material L falling from the liquid absorbing part 15 does not flow into the second chamber 1113. It may have a shape to pass gas required for vaporization from the second chamber 1113 to the first chamber 1111 while blocking the vaporization.

As a result, the liquid phase absorbing part 15 is located in the first chamber 1111 located on the upper side with respect to the partition part 17, and through the inlet hole 113 of the vaporizing part 10 Even if the liquid phase excessively introduced into the liquid phase absorbing part 15 is not vaporized and is collected and falls due to gravity, the second chamber 1113 is moved by the partition part 17 located below the liquid phase absorbing part 15. It is possible to prevent the liquid material (L) from flowing into the side.

Although the material of the partition part 17 is not limited to a specific material, a through hole 1711 and an extension hole 1731, which will be described later, are formed on the partition part 17 to form a through hole 1711 and an extension hole. Since the coil part 15 passes through the 1731, the partition part 17 is made of non-conductive plastic so that the current flowing through the coil part 15 is not lost by the partition part 17. It may be desirable to configure a non-conductor such as the like.

The partition part 17 includes a body part 171 and an extension part 173.

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

Referring to FIG. 5 , the body portion 171 includes a through hole 1711 and an attachment surface 173 .

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

The attachment surface 173 is a surface to which the liquid material L is attached, and serves to provide surface tension of the droplet. Surface tension is a type of interfacial tension, which refers to the property of the force that the surface of a liquid self-contracts to take as small an area as possible. 7 is a conceptual diagram for explaining the surface tension. Referring to FIG. 7, the molecules M existing inside the liquid material L receive force isotropically from the surrounding molecules M, while Molecules (M) located on the surface do not have a force acting from the outside of the liquid material (L), so they receive a force toward the inside of the liquid material (L). In other words, since the molecules on the surface have a greater free energy than the molecules on the inside, the liquid material (L) tends to have a small surface area, resulting in surface tension. For example, when two water droplets of the same size meet, they instantly merge into one water droplet because the surface area of a single sphere is much smaller than the sum of the surface areas of two separate spheres.

8 is a view showing the surface tension of the capillary, when the capillary is placed in the water tank in which the liquid material L is stored, as shown in FIG. 8, the weight of the liquid material L introduced into the capillary (L)

) is the circumferential surface (

) along the surface tension (

) by force (

) and the equilibrium of forces (

), the water level of the liquid material (L) inside the capillary becomes higher than the level of the surrounding liquid material (L) due to the surface tension caused by the liquid material (L). Summarizing the above relational expression,

,

surface tension (

), the unit of [

], it can be seen that the surface tension of the liquid material (L) is inversely proportional to the radius (r), and the radius (r) of the through hole 1711 should be determined in consideration of this.

Figure 9 is a view showing the surface tension in the droplet, referring to Figure 9, the surface tension in the droplet

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

Summarizing the above equation, the surface tension (

) appears as follows.

According to the above equation, the surface tension of the droplet (

) is proportional to the radius d of the droplet.

10 is a view showing the liquid material L blocking the through hole 1711 by surface tension. Referring to FIG. 10, the liquid material L excessively introduced into the liquid phase absorbing part 13 When the remaining liquid material L is not vaporized and gradually accumulates, the unvaporized liquid material L may fall on the upper side of the partition part 17 while forming droplets. At this time, the above-described through hole 1711 is formed on the partition part 17, and the size of the through hole 1711 is such that the liquid material L does not pass through the through hole 1711 due to the surface tension. When formed to a size that is not suitable, the liquid material L is prevented from passing through the through hole 1711 due to surface tension, so that the liquid material L does not flow into the second chamber 1113. Thus, leakage of the liquid material L can be prevented.

At this time, as shown in FIG. 10, the important thing is the surface tension that prevents the droplet from passing through the through hole 1711 (

) must be formed around the through hole 1711 so that the attachment surface 1713 can occur. In the absence of the attachment surface 1713, the surface tension acting in the opposite direction to the force in the direction of gravity (

) cannot be generated, and the liquid droplet flows out toward the second chamber 1113 through the through hole 1711 . For this reason, it may not be desirable to form the partition part 171 with a mesh network in which it is difficult to form the attachment surface 1713 .

FIG. 11 is a view showing a plurality of through-holes 1711 in which the attachment surface 1713 does not overlap. Referring to FIG. When the attachment surface 1713 as shown in FIG. 11 is to be formed around each through hole 1711 in order to do so, overlapping should not occur between the attachment surfaces 1713 around different through holes 1711. .

If overlap between the attachment surfaces 1713 occurs as shown in FIG. 12, the surface tension to offset the force in the direction of gravity (

) does not occur, the droplets inevitably flow out toward the second chamber 1113 through the through hole 1711 .

Therefore, when configuring the through hole 1711 on the body portion 171, the gap between the through hole 1711 is set so that overlapping between the attachment surfaces 1713 surrounding the through hole 1711 does not occur. It is necessary to adjust, and by adjusting the size of the through hole 1711 and the size of the attachment surface 1713, it is possible to prevent the liquid material L from escaping through the through hole 1711.

Similar to preventing leakage of the liquid material (L) by surface tension, the present invention may 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 a 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 thermal energy. Viscosity indicates the degree of viscosity of a fluid, is a physical unit that indicates the degree of stickiness of a fluid, and is expressed as a ratio of shear stress and shear rate.

When the through hole 1711 is formed in such a size that the liquid material L cannot pass through the through hole 1711 due to the viscosity of the liquid material L, the liquid material L may pass through the through hole Unless pressure equal to or higher 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) ) to 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), the leakage of the liquid material (L) into the second chamber 1113 may be prevented.

In addition, by forming the through hole 1711, 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 absorption The coil part 15 winding around the part 15 passes through the partition part 17 through the through hole 1711 and is located below the second chamber 1113 to form a conducting part 19 to be described later. , the coil unit 15 can receive current from the conducting unit 19 and dissipate heat.

Even if the droplets of the liquid material L collected on the upper side of the partition part 17 close the through hole 1711 due to surface tension and/or viscosity, the mouthpiece part 50 that will be described later by the user in the process of using the electronic cigarette When sucking in the mouth, the liquid drop located on the upper side of the partition part 17 can be sucked up and reabsorbed by the liquid absorption part 15.

As described above, a plurality of through holes 1711 may be formed on the body part 171 of the partition part 17, and some of the through holes 1711 formed on the body part 171 Even if it is blocked by the liquid material (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 material (L) is absorbed into the liquid phase absorbing part 15 by the suction force and opens the through hole 1711 closed by the liquid material (L).

6, the through hole 1711 is configured such 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 surface tension and/or viscosity of the liquid material (L).

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

The surface tension can be further increased. In addition, as the size W1 of the upper opening decreases, the effect of the viscosity also increases. After all, when the partition part 17 is configured as described above, a larger external force is required for the liquid material L to pass through the through hole 1711, so that the external leakage of the liquid material L is more reliably blocked. It can be.

In addition, as the size (W2) of the lower opening widens, when the air moves from the second chamber 1113 to the first chamber 1111, the flow rate increases due to Bernoulli's theorem, and thereby the through hole ( 1711) is easily removed, and the liquid material (L) separated from the surface of the partition part 17 can be easily reabsorbed by the liquid absorbing part 13 while rising. .

14 is a diagram showing a partition unit 17 according to another embodiment of the present invention, which will be described with reference to FIG. 14 hereinafter.

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

In the extension hole 1731, the size of the upper opening (W1) may be smaller than the size (W2) of the lower opening (W1 < W2). As a result, while increasing the effect of preventing the liquid material (L) from flowing into the second chamber 1113 through the upper opening of the relatively small extension hole 1731, the lower side of the relatively large extension hole 1731 Through the opening, air required for combustion is more easily introduced into the first chamber 1111 . 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, or 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 sectional opening decreases from the lower opening to the upper opening. Through this, a relatively narrower upper opening is formed and a greater pressure must be applied so that the liquid material (L) can pass through the partition portion 17, so that leakage of the liquid material (L) is more securely prevented and combustion As the air required for the air moves from the relatively wide lower opening to the relatively narrow upper opening, the flow rate increases so that the liquid material L blocking the upper opening can be more easily removed.

The attachment surface 1733 is a surface to which liquid droplets are attached, and even when the extension part 173 is formed so that the surface tension that prevents the outflow of the liquid material L through the extension hole 1731 is formed, the above-described attachment surface 1733 is formed. The attachment surface 1733 of the extension part 173 corresponding to the attachment surface 1713 of the body part 171 should be formed. When the same extension hole 1731 as shown in FIG. 15 is formed, but the extension part 173 is not formed in an inclined shape and is vertically extended as shown in FIG. 16, the extension part 173 The advantage of being able to secure a large attachment surface 1733 of (173) arises. 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 increase in the weight of the partition part 17. Therefore, the extension part 173 considers both the side surface for securing the attachment surface 1733 necessary to form the surface tension to prevent leakage of the liquid material (L) and the side surface for preventing unnecessary weight increase. It is desirable to determine the shape.

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

The conducting unit 19 is connected to the coil unit 15 of the vaporizing unit 10 and supplies current to the coil unit 15 . The conductive part 19 is connected to a battery, etc. to receive electric energy, and transfers the supplied electric energy to the coil part 15 so that heat is dissipated from the coil part 15, and the heat is used to cool the nose. As the liquid phase absorbing part 13 wound by the part 15 receives heat, the liquid material L absorbed by the liquid absorbing part 13 can be vaporized.

The liquid storage unit 30 is configured to store the liquid material (L), and refers to a configuration for supplying the liquid material (L) to the vaporizing unit (10). Preferably, as shown in FIG. 4, the liquid storage unit 30 is configured to include the vaporization unit 10 inside, even if no special measures are taken, the liquid stored in the liquid storage unit 30 The material (L) is allowed to flow naturally toward 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 may be formed therein, and one side of the gas pipe is an electronic cigarette cartridge (1). ) communicates with the outside and the other side communicates with the vaporizing unit 10 so that the smoke generated in the vaporizing unit 10 can escape to the outside through the gas tube.

18 is a diagram showing a state of use of the present invention. Referring to FIG. 18, the electronic cigarette cartridge 1 of the present invention, which prevents leakage of the liquid substance, even if the liquid substance L is excessively introduced into the liquid absorber 13 , When the non-vaporized liquid material (L) falls due to gravity, the inflow into the second chamber (1113) is blocked by the partition part (17).

However, a through hole 1711 needs to be formed in the partition part 17 so that air required for vaporization can flow into the first chamber 1111. ) The liquid material (L) is formed to a size that does not pass through the through hole 1711 due to the surface tension and viscosity of may be introduced 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 puts the mouthpiece part 50 of the electronic cigarette cartridge 1 in his mouth and sucks in the smoke. In the case of doing this, air is rapidly introduced from the lower side to the upper side, lifting the droplets covering the through-holes 1711, and these droplets are reabsorbed by the liquid absorption unit 13 located on the upper side, and oxygen required for combustion is While enabling the supply of, it is possible to promote the reuse of the non-vaporized liquid material (L).

In addition, the coil part 15 surrounding the liquid phase absorbing part 13 can be connected to the conducting part 19 through the through hole 1711, even if the partition part 17 is configured, the conducting part ( Heat is dissipated by the current that moves from 19) to the coil unit 15.
