Description

Cartomizer for electronic cigarette

The present invention relates to a cartomizer for an electronic cigarette, and more particularly, as the refill part is disposed on the upper unit, the liquid is easily transferred to the side of the upper unit without opening the upper part of the upper unit or the lower part of the lower unit during liquid refilling. To a cartomizer for an electronic cigarette that can maximize user convenience by quickly injecting and refilling the liquid, improving portability by reducing the size of the electronic cigarette, and preventing wasted liquid when refilling the liquid will be.

Tobacco is a favorite food that many people use, but it contains a large amount of various harmful substances such as tar that is harmful to the human body.

Accordingly, in recent years, for smoking cessation aid, an electronic cigarette capable of obtaining an effect similar to that of actual smoking has been developed and marketed.

Recently developed e-cigarettes have a similar appearance and are similar to those of tobacco cigarettes, and the vapor generated by heating the liquid gives the smoker a feeling as if they are actually smoking, and the harmful ingredients contained in the vapor are Compared to tobacco cigarettes, it reduces the damage caused by secondhand smoke, and does not deliver unpleasant sensations to users and people around them due to fragrances such as mint and peach added to the liquid instead of the characteristic smell of tobacco cigarettes.

Most e-cigarettes currently on sale have a method of recharging after using up a small amount of liquid stored therein, and a method of replacing a cartridge with a large amount of liquid stored in it by combining it with the main body.

However, the method of using a disposable cartridge filled with a large amount of liquid has the advantage of being convenient to use for a long time because the amount of stored liquid is large, but since the cartridge is discarded after using the liquid stored in the cartridge, garbage is generated, There was a problem in that the price per cartridge became expensive.

In order to overcome this disadvantage, the conventional e-cigarette cartomizer uses a method of filling a small amount of liquid, but since the number of times it can be used is limited depending on the amount of stored liquid, it must be frequently charged, and when moving to the outside, the liquid container is separately used. It is inconvenient to carry.

Nevertheless, disposable cartridges filled with a large amount of liquid are expensive, and as the stored liquid changes depending on the temperature or storage conditions, the cartomizer of the conventional e-cigarette has the upper housing separated as shown in FIG. Afterwards, the liquid was filled through the hole with a dropper or the like, or after the lower housing was separated, the liquid was filled through the hole with a dropper or the like.

As the electronic cigarette is a device that uses the oral cavity, hygiene problems such as a user's bacterial infection caused by oral bacteria or bacteria introduced from the outside are also emerging as important factors.

However, in the conventional cartomizer for e-cigarettes, when the lower housing is separated and the liquid is filled through the hole with a dropper, etc., the liquid moves to the vaporization unit and becomes contaminated or the liquid flows and is wasted. There were problems in that the liquid flowed or leaked during storage of the e-cigarette in a place or e-cigarette, resulting in poor hygiene, taking a lot of time to refill the liquid, and increasing the cleaning time, resulting in consumer dissatisfaction.

In addition, as shown in FIG. 1, in the conventional cartomizer for e-cigarettes, it is necessary to secure sufficient space in the e-cigarette to inject the liquid through the hole formed in the upper or lower housing, so the e-cigarette has a small outer diameter. Since it is not applied to the present invention, it is impossible to achieve miniaturization, and ultimately, there is a problem in that portability is deteriorated and manufacturing cost is increased. In particular, as described above, in today's electronic cigarette, portability is emerging as a very important factor because the electronic cigarette itself needs to be carried, unlike general cigarettes.

Furthermore, in the conventional cartomizer for e-cigarettes, even when liquid is injected through the hole after separating the upper housing as shown in FIG. As the liquid leaked during storage or use of the cigarette, it contaminates surrounding parts, thereby reducing the lifespan of the e-cigarette, increasing the maintenance cost and holding time of the e-cigarette, and reducing the safety and reliability of the e-cigarette.

Accordingly, regardless of the diameter of the e-cigarette, it is possible to easily refill the liquid with the side of the upper housing rather than the lower housing of the e-cigarette, and quickly and accurately maintain the sealed state of the e-cigarette to prevent leakage of the e-cigarette and check the e-cigarette. There is an urgent need to develop a cartomizer for

As shown in FIG. 8, the injection part 63 of the refill part of the cartomizer for electronic cigarette according to the present invention is recessed from the base part toward the central axis so that the length of the vertical cross-section of the injection part becomes smaller as it approaches the slit part. As such, as the injection part 63 is recessed from the base part toward the central axis so that the length of the vertical cross-section of the injection part becomes smaller as it approaches the slit part, the tip of the injection part adjacent to the slit part is outside even after the liquid is injected through the slit part. By maintaining the opening degree of the slit to a minimum by applying tension to bend it to a minimum, leakage of liquid during storage or use of the electronic cigarette is primarily prevented, thereby reducing maintenance costs and maintenance time due to liquid loss, and the cleanliness of the electronic cigarette can be maintained in the best condition and maximize the user's convenience.

In addition, as shown in FIG. 8, the injection part 63 of the refill part of the cartomizer for electronic cigarette according to the present invention is recessed so that the depression angle α of the injection part is 20 degrees or more to 60 degrees or less, and the injection part is formed It is made of silicone material. If the angle (α) of the injection part is less than 20 degrees, when injecting the liquid with a dropper or the like through the slit part, the incision of the slit part is not made smoothly, so it is difficult to inject the liquid, and the load is concentrated on the slit part to form the slit part However, there is a problem in that the slit part is damaged or damaged during liquid refilling of the e-cigarette, thereby reducing the lifespan and increasing the maintenance cost and maintenance time. In addition, if the angle (α) of the injection part exceeds 60 degrees, after injecting the liquid with a dropper or the like through the slit part, it does not receive sufficient tension in the thickness direction from the tip of the injection part that is impregnated from the base part, so that the hole in the slit part Since the e-cigarette does not become smaller, liquid leaks through the slit during use or storage, and the cleanliness is deteriorated, resulting in messiness, increased maintenance cost and maintenance time due to liquid loss, and consumer dissatisfaction.

The rotating part 64 is formed in a circular band shape having a hollow formed therein and having a predetermined length in the vertical direction to correspond to the shape of the seating part, and is rotatably installed in the seating part. In addition, the outer peripheral surface of the rotating part 64 may be processed on the surface of various patterns such as comb patterns, grid patterns, etc. to prevent slipping during rotation of the rotating part and to increase the friction coefficient.

In addition, the rotating part of the rotating part of the refill part of the electronic cigarette cartomizer according to a preferred embodiment of the present invention rotates the opening part through the rotation of the rotating part so that when the display part is opened, the opening part is arranged on the same central axis as the groove part. is formed through the Accordingly, the consumer can check whether the injection part and the slit part are closed from time to time with the naked eye through the display part when adjusting the air flow rate, thereby preventing secondary leakage of the liquid.

In addition, the rotating part of the refill part of the cartomizer for an electronic cigarette according to a preferred embodiment of the present invention rotates by 30 degrees or more to 80 degrees or less with respect to the central axis of rotation (C). If the rotating part rotates less than 30 degrees with respect to the central axis of rotation (C), the injection part and the slit part are disposed too adjacently, so that when the liquid is injected with a dropper or the like through the slit part, the slit part is cut smoothly. There are problems in that the liquid injection is difficult, and the load is concentrated on the slit part, and the slit part is damaged or damaged during slit part molding or e-cigarette liquid refilling, thereby reducing the lifespan, and increasing the maintenance cost and maintenance time. In addition, when the rotating part rotates more than 80 degrees with respect to the central axis of rotation (C), the rotation angle of the rotating part is excessive and the display part and the injection part are formed to be too spaced apart along the circumferential direction, and the injection formed of plastic and silicone materials There is a problem in that the rigidity of the part and the slit part is lowered, and the horizontality of the part is reduced, so that liquid leakage may occur due to breakage, and the life and durability of the equipment is reduced.

The opening part 65 extends along the circumferential direction on a part of the rotation part and is formed through the rotation part to selectively open and close the display part or the injection part according to the rotation angle of the rotation part. That is, as the opening 65 is rotated in conjunction with the rotating unit, the display unit and the injection unit of the base unit which are fixedly installed according to the rotation angle of the rotating unit are positioned to communicate the display unit and the injection unit with the outside.

The slit portion 66 extends along the circumferential direction of the injection portion and is formed by cutting the center of the injection portion. In addition, as shown in FIG. 6, the length of the open part (K) of the refill part of the cartomizer for electronic cigarette according to the present invention is formed to be 0.1 times or more and 0.3 times or less of the circumferential length (O) of the rotating part, and the length of the slit part (L) is formed to be not less than 0.4 times and not more than 0.7 times the length of the opening (K). If the length of the opening (K) is less than 0.1 times the circumferential length (O) of the rotating part, the length of the opening is small and the manufacturing cost is increased as the rotating part must be precisely manufactured, and the liquid is injected through the slit with a dropper When the slit part is not cut smoothly, liquid injection is difficult, the load is concentrated on the slit part, and the slit part is damaged or damaged during slit part molding or e-cigarette liquid refilling, reducing the lifespan, and reducing maintenance costs and maintenance time. There is a growing problem. In addition, when the length of the opening (K) exceeds 0.3 times the circumferential length (O) of the rotating part, the length of the opening is too large, so the rigidity and durability of the part are reduced, and the life is reduced, and the liquid After injection, the hole in the slit does not become small because it does not receive sufficient tension in the thickness direction from the tip of the injection unit that is impregnated from the base. There is a problem in that the maintenance cost and maintenance time are increased due to the loss of the liquid, resulting in consumer dissatisfaction.

If the length of the slit (L) is less than 0.4 times the length of the opening (K), the length of the slit is too short, so when injecting the liquid with a dropper through the slit, the incision of the slit is not made smoothly. It is difficult, and the load is concentrated on the slit part, so that the slit part is damaged or damaged during slit part molding or e-cigarette liquid refilling, thereby reducing the lifespan, and increasing maintenance cost and maintenance time. In addition, if the length of the slit (L) exceeds 0.7 times the length of the opening (K), the length of the slit is too large, and the rigidity and durability of the injection part are reduced, thereby reducing the lifespan, and removing the liquid with a dropper through the slit After injection, the hole in the slit does not become small because it does not receive sufficient tension in the thickness direction from the tip of the injection unit that is impregnated from the base. There is a problem in that the maintenance cost and maintenance time are increased due to the loss of the liquid, resulting in consumer dissatisfaction.

The stepped portion 67 is formed to protrude in the horizontal direction to a portion of the body portion to limit the rotation angle of the rotating portion. In this way, the rotation angle of the rotating part is limited by the stepped part to prevent leakage of the liquid, and liquid refilling is possible to the side of the upper unit through a simple operation.

The confirmation part 68 is coupled to the receiving groove 69 concavely formed on the upper part of the main body, and is formed of an elastic material to check the rotational state of the rotating part, and the confirmation part is extended or shortened with a click sound by the rotation of the rotating part. In addition to the display unit, the user can intuitively and clearly inform the user of the current position of the opening through sound to prevent leakage in the third place.

Accordingly, in the cartomizer for e-cigarette according to the present invention, as the liquid is refilled through the slit of the injection unit formed on the side of the upper unit, there is no need to separately form a hole for refilling the liquid. By applying this method, the electronic cigarette can be miniaturized and compact to increase portability, reduce manufacturing cost, and simply rotate the opening formed on the rotating part when replacing the liquid refill. As there is no need to inject the liquid into the hole formed in the upper unit or the lower unit after separating the lower part, it is prevented that the liquid overflows or leaks when refilling the liquid, thereby minimizing liquid waste, thereby reducing the maintenance cost and maintenance time of the e-cigarette. In the case of liquid refill replacement, liquid refill is performed while intuitively checking the complete opening of the slit part and the complete sealing of the display part through the confirmation part when rotating the rotating part during liquid refill replacement. It is possible to prevent leakage to maintain cleanliness, to prevent damage to equipment or hands due to liquid leakage in advance, thereby increasing the lifespan of e-cigarettes, and maximizing the safety and reliability of e-cigarettes.

Mouthpiece 10, upper unit 20, central unit 30, lower unit 40, vaporization unit 50, refill unit 60, and air flow control of the cartomizer for electronic cigarette according to the present invention A coating layer may be formed on the part 70 .

The coating layer (not shown) is to be coated using a coating composition, and the coating layer using the coating composition may exhibit an antistatic effect and a waterproof effect. Specifically, the coating layer prevents adhesion of dust and the like and at the same time has a water repellent effect, thereby exhibiting an excellent waterproof effect. More specifically, the coating composition of the present invention may include a siloxane-based compound represented by the following Chemical Formula 1; Conductive fillers and carbon nanotubes may include:

[Formula 1]

where n is an integer from 1 to 100.

After forming the coating layer using the coating composition of the present invention, the contact angle measurement result was confirmed to be 130 to 140 degrees, as can be seen in the range of the contact angle, it will be said that the waterproof effect appears by the coating layer.

The conductive filler may be selected from the group consisting of silica, alumina, and mixtures thereof. The conductive filler has a particle diameter of 70 to 100 μm, but is not limited to the above example. The conductive filler may exhibit electrical conductivity in the antistatic layer.

The carbon nanotubes are included in a small amount, so that the antistatic effect in the antistatic layer can be continuously maintained. Considering that carbon nanotubes are expensive conductive fillers, a small amount is included in the coating layer in the present invention, thereby maintaining a continuous antistatic effect.

More specifically, the coating layer of the present invention may include a siloxane-based compound represented by Formula 1; Including conductive fillers and carbon nanotubes, it may exhibit an antistatic effect. The siloxane-based compound is divided into a hydrophilic portion and a hydrophobic portion. The hydrophilic moiety is capable of hydrogen bonding with a water molecule by an oxygen atom containing a lone pair of electrons. On the other hand, as a hydrophobic group including an alkyl group or an aryl group is further included, a hydrophobic group acts on the opposite part of the hydrophilic part. Accordingly, the hydrophilic portion is positioned on the surface of the antistatic layer, and the hydrophobic portion is positioned in the opposite direction, thereby exhibiting a semi-permanent antistatic effect.

For forming the coating layer, the coating composition may include a siloxane-based compound represented by Chemical Formula 1; It can be prepared by mixing a conductive filler, carbon nanotubes, and an organic solvent.

The organic solvent may be selected from the group consisting of ethanol, methanol, butanol, hexane, propane, toluene, phenol, and mixtures thereof.

The coating composition may include 40 to 60 parts by weight of the siloxane-based compound represented by Chemical Formula 1, 20 to 40 parts by weight of the conductive filler, and 5 to 15 parts by weight of the carbon nanotubes based on 100 parts by weight of the organic solvent. In the case of the above range, a synergistic effect is expressed to the extent that the antistatic and waterproof effect due to the interaction of each component has a critical significance, and when it is out of the above range, the synergistic effect is rapidly reduced or almost absent.

More preferably, the viscosity of the coating composition is 1500 to 1800 cP, and when the viscosity is less than 1500 cP, it flows down during coating on one surface of the base layer, so that the formation of the coating layer is not easy, and when it exceeds 1800 cP, uniform There is a problem in that the formation of the coating layer is not easy.

2. Preparation of coating layer After coating the coating composition of DX1 to DX5 on one surface of the substrate layer, it was cured to form a coating layer. In order to test the antistatic and uniform coating layer formation, an experiment was conducted using polycarbonate as a base layer instead of a solar panel.

[Experimental Example 1: Antistatic effect test]

1. Viscosity Measurement

Before forming the antistatic layer on one surface of the polycarbonate base layer, the viscosity of the antistatic composition was measured. Viscosity was measured using a rheometer (Rheometer, Compac-100, Sun Sci. Co., Japan). The viscosity measurement results are shown in Table 2 below.

2. Measurement of Surface Electrical Resistance For the protective layer in which the antistatic layer of TX1 to TX5 is formed on one surface of the polycarbonate substrate, the surface electrical resistance was measured using a Resistance Meter SIMCO resistor ST-4 (23°C, 50% relative humidity). . As a comparative example, the surface electrical resistance of the polycarbonate substrate on which the antistatic layer was not formed was also measured.

4.4×10 ⁷ to 2.1×10 ⁸
6.5×10 ⁷ to 4.5×10 ⁸
5.8×10 ⁸ to 7.8×10 ⁸

According to Table 3, compared to the comparative example in which the antistatic layer is not formed, since the surface electrical resistance of TX 1 to TX5 is low, the electrical conductivity is excellent, and it can be confirmed that an excellent antistatic effect is exhibited. Evaluation of surface appearance

Due to the difference in viscosity of the antistatic composition, after the coating layer was prepared, a sensory evaluation was performed on whether a uniform surface was formed. Whether or not a uniform coating layer was formed was evaluated, and evaluation was performed according to the following criteria.

When the coating layer is formed, if the viscosity is less than a certain viscosity, a flow occurs on the surface of the polycarbonate, and after the curing process, it is difficult to form a uniform coating layer. Accordingly, there may be a problem in that the production yield is lowered. In addition, even when the viscosity is too high, it is difficult to uniformly apply the composition, making it impossible to form a uniform coating layer. Measurement of water repellency angle

After forming the coating layer on the base layer, the results of measuring the water repellency angle are shown in Table 5 below.

As shown in Table 5, after forming the coating layer using the coating composition of TX1 to TX5, the result of measuring the contact angle was confirmed. For TX1 and TX5, the receding contact angle was measured to be less than 10 degrees. That is, when it is out of the optimal range for preparing the coating composition, it was confirmed that the phenomenon of pinning water droplets occurs. On the other hand, it was confirmed that the peening phenomenon did not occur in TX2 to 4, thereby exhibiting an excellent waterproof effect.
