1 and 2 illustrate an electronic cigarette (EC) according to an embodiment of the present invention.

1 and 2, the electronic cigarette (EC) of the present invention largely includes a cartridge 100 and a battery receiver 200.

The cartridge 100 stores a liquid tobacco material and vaporizes it through the built-in heater 140 to provide a gaseous tobacco material, thereby allowing the user to replace conventional tobacco smoke.

The battery receptor 200 is attached to and detached from the cartridge 100 by embedding the battery 220, thereby supplying power to the heater 140 and serving as a handle for the user to hold the electronic cigarette EC.

Here, the electrode of the heater 140 is exposed through the lower portion of the cartridge 100 to be electrically connected to the electrode of the battery 220 exposed in the coupling cover 210, the cartridge 100 and the battery receptor 200 The locking groove 101 formed on the outer circumferential surface of the cartridge 100 and the locking protrusion 211 formed on the inner circumferential surface of the coupling cover 210 are mechanically coupled by being fitted together. However, it is clarified that the above-described technical content corresponds to one embodiment and the technical idea of the present invention is not limited thereto.

The cartridge 100 is inserted into the battery receptor 200 and operates, and vaporizes a liquid tobacco material through the following process and provides it as cigarette smoke to the user.

When the cartridge 100 is seated and coupled to the battery receptor 200, the vacuum detection sensor 230 is switched to the sleeping mode and waits, and when the user transmits the suction power through the mouthpiece 120, the cartridge 100 and the battery As air in the space formed between the containers 200 flows into the cartridge 100, the pressure in the space where the cartridge 100 and the battery container 200 face each other is reduced (vacuum). At this time, the vacuum sensor 230 detects a pressure reduction state, converts the electronic cigarette EC, which was previously in the sleeping mode, into an operation mode, and supplies power to the heater 140 to generate heat to vaporize the liquid tobacco material. Here, the vacuum sensor 230 adjusts the amount of heat generated in proportion to the heat generation operation of the heater 140 and the size of the suction power by calculating the size of the user's suction operation and suction power according to the pressure drop. Meanwhile, new air is introduced and filled in the space between the cartridge 100 and the battery container 200 whose pressure is reduced through the gap between the cartridge 100 and the coupling cover 210 or the battery container 200.

In addition, the operation process of the electronic cigarette (EC) of the present invention can be easily recognized by the user through the operation lamp 240 installed to be exposed to the outer circumferential surface of the battery receptor 200, and although not shown in the drawing, the battery receptor ( It goes without saying that the USB charging terminal is installed at the bottom of 200) to charge the battery 220.

Hereinafter, a detailed configuration of the cartridge 100 will be described in detail with reference to FIGS. 3 to 5.

3 and 4, the cartridge 100 includes a housing 110 forming the entire outer shape of the cartridge 100, a mouthpiece 120 receiving suction power of a user, and a mixing path of a liquid tobacco material and air, or It includes a mixing chamber 130 forming a space and a heater 140 for heating.

The housing 110 constitutes the main body of the cartridge 100, and forms the overall appearance of the cartridge 100, as well as the air inlet path (IR) and the discharge path (OR) formed therein, and is used for liquid cigarettes. It includes a storage space 117 in which the material is accommodated. The cartridge 100 of the present invention has a configuration in which a liquid tobacco material is stored therein, and the reception and flow of fluid, such as receiving air from the outside, must be considered. It is preferable that the rest of the parts except for the upper part, which is a part for discharging the upper tobacco material, are provided in an integrated state for closure. The housing 110 includes a base part 111, a cover part 112, an inflow seal 113, a liquid mixing tube 114, and an inner cover 115.

The base part 111 is combined with the cover part 112 in a stacked structure to form a lower portion of the housing 110 as well as to form a part of the inflow path (IR), the inlet pipe (111a), the closing cap ( 111b), an inlet 111c, and a base horizontal surface 111d. The inlet pipe 111a is a cylindrical tube having a shape that extends from the bottom surface of the base part 111 to the top, and provides a straightened first inlet passage 1IR that is not bent among the air inlet paths IR. To form. At this time, the inlet pipe (111a) is formed with a predetermined width so that a large amount of air can be introduced, and to prevent the inflow of foreign substances, as well as to prevent deformation by heat or physical force, the closing cap 111b having a certain strength ) Is installed to close the opening. However, in order to introduce air, an inlet 111c having a bent path is formed in the facing portion of the closing cap 111b and the inlet pipe 111a so that a small amount of air is continuously supplied to the inlet pipe 111a. The base horizontal surface 111d is formed in a horizontal direction between the inflow pipe 111a and the mixing chamber 130 to provide one surface forming a third inflow path 3IR to be described later.

As described above, the cover part 112 is stacked on top of the base part 111 and combined to form a part of the inflow path IR, and the mixing pipe binding hole 112a, the cover vertical surface 112b, and the cover It includes a horizontal plane (112c). The mixing tube binding hole 112a is a through hole formed in the center to accommodate the liquid mixing tube 114 to be described later, and the cover vertical surface 112b is a second inflow path 2IR together with the outer peripheral surface of the inflow tube 111a described above. ) Is formed vertically at a position facing the outer circumferential surface of the inlet pipe 111a, and the cover horizontal surface 112c also forms a third inflow path 3IR together with the base horizontal surface 111d described above, It is formed horizontally at a position facing the base horizontal surface 111d.

A technique for secondaryly preventing leakage of a liquid tobacco material occurring in the inflow path IR using such a refraction and extending structure will be described in detail again in FIG. 6 to be described later.

The inflow sealing 113 is a sealing member fitted in a portion where the base part 111 and the cover part 112 are combined, and closes the combined gap to form the inflow path IR.

The liquid mixing pipe 114 is coupled to the mixing pipe binding hole 112a and is connected to the inflow path IR, thereby providing an exhaust path OR of the air introduced through the inflow path IR.

The inner cover 115 is placed between the mouthpiece 120 and the housing 110, covers the upper portion of the storage space 117 and the upper portion of the liquid mixing tube 114, and is coupled to the housing 110, thereby forming the housing 110 ) To form the top surface. In the upper portion of the storage space 117, a through-shaped injection hole 115a is formed to inject and store a liquid tobacco material into the storage space 117, and a liquid mixing pipe is formed at the upper portion of the liquid mixing pipe 114 A discharge hole 115b having a cross-sectional area narrower than the cross-sectional area of 114 is formed to induce an inertial collision of the gaseous tobacco material discharged through the discharge path OR and the gravitational sedimentation of fine droplets accordingly.

The fixing protrusion 116 protrudes from the outer circumferential surface of the housing 110 to form a fixing support point when the mouthpiece 120 is coupled to the housing 110, and the protrusion height increases toward the direction in which the mouthpiece 120 is inserted. Is formed to be

The storage space 117 is a space for storing the liquid tobacco material. In this embodiment, the liquid mixing pipe 114 is surrounded by the liquid mixing pipe 114 or the liquid mixing pipe 114 penetrates the storage space 117 to be transparent. It is formed and provided in a structure in which the amount of the liquid tobacco material stored in the storage space 117 is exposed to the outside. Through this, the user can intuitively check the remaining amount of the liquid tobacco material, and the liquid tobacco material supplied to the mixing chamber 130 through the liquid induction hole 131 to be described later is symmetrical on the horizontal plane of the front, rear, left and right. By being attracted to the structure, it is possible to improve the mixing ratio of air and liquid tobacco substances according to an equal load. In the exemplary embodiment of the present invention, the storage space 117 is illustrated and described in the form of a chamber forming a side portion of the housing 110, but it is of course possible that the storage space 117 may be a separate chamber accommodated in the housing 110.

On the other hand, the mouthpiece 120 is coupled to the upper portion of the housing 110 to form a suction path BR extending from the discharge path OR, the pressure protrusion 121, the fixing groove 122, the suction port ( 123), a refractive space 124 and a suction seal 125. The pressing protrusion 121 is inserted into the injection hole 115a of the above-described inner cover 115 to close the injection hole 115a and is inserted to a set depth inside the storage space 117, and the storage space 117 By filling the upper space of the storage space 117, the pressure of the upper space of the storage space 117 is increased. That is, the storage pressure of the liquid tobacco material in the storage space 117 is increased. In addition, the fixing groove 122 is formed in a shape inserted into the inner circumferential surface of the mouthpiece 120 or penetrated in order to receive and fix the fixing protrusion 116 described above. In addition, the suction port 123 allows the user to receive suction power through a through hole formed on the upper portion of the mouthpiece 120, and inertial gaseous tobacco material that is formed and discharged on a virtual axis different from the discharge path (OR). It causes gravitational sedimentation in accordance with the collision and is reduced to a liquid tobacco material. In addition, the refraction space 124 is provided on the suction path BR where the positions of the discharge path OR and the inlet 123 are formed with respect to different axes and refracts to form a vortex flow by convection of the gaseous tobacco material. By making it possible to increase the probability of contact between droplets, external outflow of droplets can be greatly reduced. It goes without saying that such refraction of the suction path BR can reduce the ingress of foreign substances in the path along with the function of removing droplets. Herein, the description of the droplets will be briefly described, and the vaporized gaseous tobacco material is incorporated into the flow of air in a condensed mist/aerosol state and provided to the user. However, in some of the vaporized gaseous substances, particles of the gaseous tobacco substance in the mist/aerosol state are agglomerated with each other, and are provided to the user in the form of droplets of which the size is increased, thereby causing the user to feel severe discomfort. In addition, the suction sealing 125 is provided between the inner cover 115 and the suction port 123 to seal the liquid tobacco material leaking out from the injection hole 115a of the inner cover 115.

The mixing chamber 130 is provided in a tube shape and connects the inflow path IR and the discharge path OR as a space for mixing formed in the lower part of the liquid mixing pipe 114, and the liquid induction hole 131 and the wick 132 ). The liquid induction hole 131 is formed with at least one through hole along the outer circumferential surface of the mixing chamber 130 based on the virtual axis of the mixing chamber 130 to connect the mixing chamber 130 and the storage space 117, A path through which the liquid tobacco material in the storage space 117 can be attracted to the mixing chamber 130 is provided by the flow of air introduced through the inlet path IR and directed to the discharge path OR. In addition, the wick 132 absorbs the liquid tobacco material attracted from the liquid attraction hole 131 and provides it to the adjacent heater 140, which is formed in a fiber structure and is formed in a liquid attraction hole along the inner circumferential surface of the mixing chamber 130. It is installed to cover 131. Here, it goes without saying that the height or area of the wick 132 may be set differently along the inner circumferential surface of the liquid mixing pipe 114 as necessary.

5, the heater 140 is provided in the mixing chamber 130 to heat and vaporize the liquid tobacco material absorbed by the wick 132 through the liquid induction hole 131, the heating element 141 and It includes a heat carrier 142. The heating element 141 is a heating coil having a spiral wound structure along the length direction of the heat transfer member 142 through insert injection, and generates heat by power supplied by being electrically connected to the battery 220. The heat transfer body 142 accommodates the above-described heating body 141 therein, and is provided in a tube shape including a communication hole 143 connecting the inflow path IR and the discharge path OR. It transfers heat to the liquid tobacco material absorbed by the wick 132 and is formed of a ceramic material that is a rigid member. The heater 140 including the heating body 141 and the heat transfer body 142 may prevent leakage of more than a set amount of the liquid tobacco material attracted to the liquid attraction hole 131 through the rigidity of the ceramic. In addition, the generation of harmful substances can be suppressed by preventing combustion of the wick 132 by using the characteristics of ceramic.

Table 1 shows the composition ratio of the heater 140 composed of the heating body 141 and the heat transfer body 142.

Configuration	importance(%)	Chemical name	Weight ratio (%)
Heat carrier (Ceramic)	50 to 70%	SiO 2	≥91%
		Fe 2 O 3	≤2.5%
		Al 2 O 3	≤6.5%
Heating element (Wire)	30-50%	Fe	≥68%
		Cr	≤25%
		Al	≥7%

The heating element 141 occupies 30 to 50% of the total weight of the heater 140 and is composed of Fe, Cr, and Al. Fe and Al are preferably set to have a weight ratio of 68% and 7% or more, respectively. In addition, the heat transfer body (142, Ceramic body) occupies 50 to 70% of the total weight of the heater 140, SiO ₂ , Fe ₂ O ₃ , It is composed of Al ₂ O ₃ . Fe ₂ O ₃ , It is preferable that Al ₂ O ₃ is set to have a weight ratio of 2.5% and 6.5% or less, respectively.

Hereinafter, a technique for suppressing primary leakage of liquid tobacco material using the configuration of the storage space 117 and the mixing chamber 130 will be described in detail with reference to FIG. 6.

Referring to Figure 6, the cartridge 100 of the present invention is installed in the existing mixing chamber 130 to provide a heater 140 used to vaporize a liquid tobacco material in a cylindrical or tubular arrangement and fixed in the mixing chamber 130 Also, by pressing the wick 132 covering the liquid attraction hole 131 with the heat transfer member 142, leakage of more than a set amount of the liquid tobacco material attracted from the storage space 117 is prevented. Through this, it is possible to allow the liquid tobacco material to be attracted to flow only by the suction power of the user without leakage due to its own weight.

At this time, the tube-shaped heat transfer body 142 is made of a ceramic material and is provided with a rigid member capable of providing a certain rigidity, so that the heat of the heating body 141 or the pressure of the liquid tobacco material attracted from the storage space 117 It is possible to press the wick 132 described above without being deformed or moved by.

In addition, the heat transfer body 142 made of ceramic material receives heat from the heating body 141 made of metal and is heated, so that the temperature does not change instantly, but gradually changes, as well as the temperature of the heat transfer body 142 made of metal. ) Or can be maintained longer than the heating element 141. Therefore, the heat transferred from the heat transfer body 142 made of such a ceramic material only heats and vaporizes only the liquid tobacco material absorbed by the wick 132 and may not burn the wick 132 or the liquid tobacco material. In addition to reducing the loss of the vaporization function of the cartridge 100 due to the combustion of 132, harmful substances contained in the gaseous tobacco material due to the combustion of the wick 132 and the liquid tobacco material and the resulting burnt taste Can be greatly suppressed.

On the other hand, suppressing the primary leakage through the above-described configuration of the ceramic material heat transfer body 142 eventually solves the problem of requiring a greater suction power of the user to attract the liquid tobacco material from the storage space 117. I hold it. Accordingly, there is a need to increase the attractive force by increasing the pressure of the liquid tobacco material accommodated in the storage space 117.

Specifically, the storage space 117 communicated with the mixing chamber 130 through the liquid induction hole 131 is a liquid induction hole 131 of a small diameter, so that the liquid tobacco material does not leak out as in the principle of a syringe. , It is attracted by the user's suction force and is absorbed by the wick 132 of the inner circumferential surface of the mixing chamber 130, and thus is discharged to the outside. Thereafter, when the liquid tobacco material in the wick 132 is heated and vaporized by the heater 140, the liquid tobacco material in the storage space 117 is reabsorbed by the wick 132 and is discharged. However, the amount of outflow of the liquid tobacco material leaked to the outside by the suction force of the same user by the heat transfer body 142 made of ceramic material adjacent to the liquid induction hole 131 with the wick 132 interposed therebetween and the path is in close contact Is bound to decrease. Accordingly, in order to prevent functional loss of the e-cigarette (EC) vaporizer, the user's suction power is supplemented by increasing the receiving pressure of the storage space 117, so that the amount of outflow of the liquid tobacco material can be kept constant. At this time, a plurality of liquid induction holes 131 are formed in a symmetrical position with respect to the virtual central axis of the tube-shaped mixing chamber 130, and the heat transfer body 142 presses the liquid induction holes 131 symmetrically. Thus, it is possible to maintain the balance of the power of the front, rear, left and right sides.

Referring to FIG. 7, for this purpose, the pressure protrusion 121 of the mouthpiece 120 is inserted to a set depth in the storage space 117 through the injection hole 115a of the inner cover 115 to be inserted into the storage space 117. By increasing the receiving pressure, it is possible to maintain the attractive force of the liquid tobacco material described above. In addition, in order to prevent the mouthpiece 120 including the pressing protrusion 121 from being separated from the housing 110 due to the increased receiving pressure, the fixing protrusion 116 and the fixing groove 122 are provided with the housing 110 and the mouse. It is provided for the coupling of the pieces 120, and at this time, the fixing protrusion 116 is formed so that the protruding height increases in the direction in which the mouthpiece 120 is inserted, so that the mouthpiece 120 is easily attached to the housing 110. It is combined in a way that does not make it easier to escape.

In the following, referring to FIG. 8, the secondary leakage of liquid tobacco material through the refracted inflow path IR formed by the stacked assembly structure of the base part 111 and the cover part 112 of the housing 110 It will be described in detail the technique to suppress the.

Referring to FIG. 8, the inflow path IR of the cartridge 100 of the present invention is formed through a coupling structure by lamination of the base part 111 and the cover part 112 as described above.

In the base part 111, the first inlet path 1IR is formed in a linear shape without being refracted along the traveling direction of the air in the mixing chamber 130, thereby forming a constant step with the inlet end of the air in the mixing chamber 130. The second and third inflow paths 3IR are formed in a structure in which the flow path is refracted differently from the first inflow path 1IR to connect the first inflow path 1IR and the mixing chamber 130. Therefore, it is preferable that the second and third inflow paths 3IR are formed by assembling the base part 111 and the cover part 112.

Here, the second inlet path 2IR is formed in a direction opposite to the traveling direction of the air in the mixing chamber 130, so that the flow of the liquid tobacco material is greatly restricted compared to the flow of air, so that reverse flow can be prevented. .

In addition, the third inlet passage 3IR is formed toward the inlet end of the air of the mixing chamber 130 when the second inlet passage 2IR is formed in the reverse direction, and the second inlet passage 2IR It is formed in a structure with a stepwise/continuous slope from the end. This allows the liquid tobacco material leaked from the mixing chamber 130 and accumulated in the air inflow path IR to be easily re-entered into the mixing chamber 130 by the suction force of the user.

Further, although not shown in the drawing, the third inlet path 3IR is formed toward the inlet end direction of the air in the mixing chamber 130, and has a curved ring structure, a ring structure, or a spiral structure along the mixing chamber 130. It may be formed and connected to the mixing chamber 130. The cartridge 100 of the present invention may be in an upright state during a user's suction operation, but may be in a lying state or upside down when carrying. Accordingly, the third inflow path 3IR is a symmetrical ring within a 180° range curved along the periphery of the mixing chamber 130, a ring in a 360° range, or a lower side in consideration of both the standing state or the lying state. Needless to say, it can be formed in a spiral structure with a narrower radius.
