However, an inlet 111c having a refracted path is formed at the facing portion of the closing cap 111b and the inlet pipe 111a to allow the inflow of air so that a small amount of air is continuously supplied to the inlet pipe 111a. The base horizontal surface 111d is provided in a horizontal direction between the inflow pipe 111a and the mixing chamber 140 to provide one surface forming the third inflow path 3IR, which will be described later.

As described above, the cover part 112 is formed to form a part of the inflow path IR by being laminated and coupled to the upper part of the base part 111.

A discharge hole 115b having a narrower cross-sectional area than the cross-sectional area of 114 is formed to induce an inertia collision of the gaseous tobacco material discharged through the discharge path OR and thereby gravity settling of the droplets.

The fixing protrusion 116 protrudes on the outer circumferential surface of the housing 110, so that when the mouthpiece 120 is coupled to the housing 110, the fixing protrusion 116 forms a fixed support point, and the protrusion height increases as the mouthpiece 120 is fitted. It is formed to.

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 pressing projection 121, the fixing groove 122, the suction port ( 123, the refractive space 124 and the suction seal 125.

By filling the upper space of the, the pressure of the upper space of the storage tank 130 is increased. That is, the storage pressure of the storage tank 130 increases the receiving pressure of the tobacco material. In addition, the fixing groove 122 is formed in a shape or penetrated into the inner circumferential surface of the mouthpiece 120 in order to receive and fix the fixing protrusion 116 described above. In addition, the suction port 123 may be provided with a user's suction power through the through-hole formed in the upper portion of the mouthpiece 120, and inertial gaseous tobacco material formed and discharged on a virtual axis different from the discharge path OR. Gravitational sedimentation upon impact causes reduction to liquid tobacco material. In addition, the refraction space 124 is formed on the suction path BR, which is formed by refracting and refracting the positions of the discharge path OR and the suction port 123 to form a vortex flow due to the convection of the gaseous tobacco material. As a result, the contact probability between the droplets can be increased to greatly reduce the outflow of the droplets. The refraction of the suction path BR can of course reduce the introduction of foreign substances in the path together with the function of removing the droplets. Briefly describing the droplets here, the vaporized gaseous tobacco material is incorporated into the flow of air in a condensed mist / aerosol state and provided to the user. However, some of the vaporized gaseous material is agglomerated with particles of the gaseous tobacco material in the mist / aerosol state, provided to the user in the state of the larger droplet size to make the user 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 from the injection hole (115a) of the inner cover 115.

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 140 through the liquid attraction hole 141 which will be described later is symmetrical on the horizontal plane of the front, rear, left and right By attracting the structure, it is possible to improve the mixing ratio of the air and the liquid tobacco material according to the uniform load. In the embodiment of the present invention, although the storage tank 130 is shown and described in the form of a chamber forming the side of the housing 110, it may be a separate chamber form accommodated in the housing 110, of course.

The mixing chamber 140 is formed in a tube shape and connects the inflow path IR and the discharge path OR to a space for mixing formed in the lower portion of the liquid mixing tube 114, and the liquid attracting hole 141 and the wick 142. ). At least one through hole is formed along the outer circumferential surface of the mixing chamber 140 based on the virtual axis of the mixing chamber 140 to connect the mixing chamber 140 and the storage tank 130. It provides a path through which the liquid tobacco material in the storage tank 130 can be attracted to the mixing chamber 140 by the flow of air flowing through the inflow path (IR) toward the discharge path (OR). In addition, the wick 142 absorbs the liquid tobacco material attracted from the liquid attraction hole 141 and provides the adjacent material to the heater 150. The wick 142 is formed in a fiber structure and forms a liquid attraction hole along the inner circumferential surface of the mixing chamber 140. 141 is installed to cover. Here, the height or area of the wick 142 may be set differently along the inner circumferential surface of the liquid mixing tube 114 as necessary.

Referring to FIG. 5, the heater 150 is provided in the mixing chamber 140 to heat and vaporize the liquid tobacco material absorbed in the wick 142 through the liquid attraction hole 141. A heat carrier 152. The heating element 151 is a heating coil having a spirally wound structure along the length direction in the heat transfer body 152 through insert injection, and generates heat by a power source electrically connected to the battery 220. The heat transfer body 152 accommodates the above-described heating element 151 therein, and is provided in a tube shape including a communication hole 153 connecting the inflow path IR and the discharge path OR of the heating element 151. It transfers heat to the liquid tobacco material absorbed by the wick 142 and is formed of a ceramic material which is a rigid member. The heater 150 including the heating element 151 and the heat transfer element 152 may prevent leakage of a set amount or more of the liquid tobacco material attracted to the liquid inducing hole 141 through the rigidity of the ceramic. In addition, by using the characteristics of the ceramic to prevent the combustion of the wick 142, it is possible to suppress the generation of harmful substances.

Table 1 shows the composition ratio of the heater 150 composed of the heating element 151 and the heat transfer element 152.

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

The heating element 151 is 30 to 50% of the total weight of the heater 150 and is composed of Fe, Cr, 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 152 (Ceramic body) occupies 50 to 70% of the total weight of the heater 150, 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 be set to have a weight ratio of 2.5% and 6.5% or less, respectively.

Hereinafter, referring to FIG. 6, a technique of suppressing primary leakage of a liquid tobacco material using the storage tank 130 and the mixing chamber 140 will be described in detail.

Referring to FIG. 6, the cartridge 100 of the present invention is disposed in the mixing chamber 140 by providing a heater 150, which is installed in the existing mixing chamber 140 to vaporize a liquid tobacco material, in a cylindrical or tubular shape. The wick 142 covering the liquid attraction hole 141 is pressed by the heat transfer member 152 to prevent leakage of a set amount of the liquid tobacco material drawn from the storage tank 130. Through this, the attracted liquid tobacco material can be made to flow only by the suction force of the user without leaking by its own weight.

At this time, the tube-shaped heat transfer member 152 is made of a ceramic material is provided with a rigid member that can provide a certain rigidity, the heat of the heating element 151 or the pressure of the liquid tobacco material attracted from the storage tank 130 The wick 142 described above can be pressed without being deformed or moved.

In addition, the heat transfer body 152 of the ceramic material is heated by receiving heat from the heating body 151 of the metal material, so that the temperature is not changed instantaneously but gradually changes, and the temperature of the heat transfer body 152 of the metal material is changed. Or longer than the heating element 151. Therefore, the heat transferred from the heat transfer body 152 made of ceramic material may heat and vaporize only the liquid tobacco material absorbed in the wick 142 and may not burn the wick 142 or the liquid tobacco material. To reduce the loss of the vaporization function of the cartridge 100 due to the combustion of (142), as well as the harmful substances contained in the gaseous tobacco material resulting from the combustion of the wick 142 and the liquid tobacco material and resulting burnt taste Can be greatly suppressed.

On the other hand, suppressing primary leakage through the configuration of the heat transfer body 152 of the ceramic material is a problem that requires a larger suction force of the user in order to attract the liquid tobacco material from the storage tank 130 in the end Holding Therefore, it is necessary to increase the attraction pressure of the liquid tobacco material contained in the storage tank 130 to increase the attraction force.

In detail, the storage tank 130 communicated with the mixing chamber 140 through the liquid attraction hole 141 does not leak the liquid tobacco material to the outside as in the principle of a syringe due to the small diameter liquid attraction hole 141. Induced by the suction force of the user, it is absorbed by the wick 142 of the inner circumferential surface of the mixing chamber 140 and flows out. Subsequently, when the liquid tobacco material of the wick 142 is heated and vaporized by the heater 150, the liquid tobacco material of the storage tank 130 is again absorbed by the wick 142 and flows out. However, the heat transfer body 152 of the ceramic material closes the path adjacent to the liquid attraction hole 141 with the wick 142 therebetween, so that the amount of the liquid tobacco material leaked to the outside by the suction force of the same user. Is bound to decrease. Therefore, in order to prevent the functional loss of the electronic cigarette (EC) vaporizer, by increasing the receiving pressure of the storage tank 130 to supplement the suction force of the user, the external outflow of the liquid tobacco material can be kept constant. At this time, the liquid induction hole 141 is formed in a plurality of positions symmetrical with respect to the virtual center axis of the tubular mixing chamber 140, the heat transfer member 152 to press the liquid induction hole 141 symmetrically To maintain the balance of force on the front, rear, left, and right sides.

Referring to FIG. 7, for this purpose, the pressing protrusion 121 of the mouthpiece 120 is inserted to the set depth in the storage tank 130 through the injection hole 115a of the inner cover 115 to store the inside of the storage tank 130. By raising the receiving pressure, it is possible to maintain the attraction force of the above-mentioned liquid tobacco material. In addition, in order to prevent the mouthpiece 120 including the pressing protrusion 121 from being released from the housing 110 by the increased accommodation pressure, the fixing protrusion 116 and the fixing groove 122 are provided with the housing 110 and the mouse. Is provided for the coupling of the piece 120, in this case, the fixing projection 116 is formed so that the protrusion height is increased in the direction in which the mouthpiece 120 is fitted, the mouthpiece 120 is easy to the housing 110 Are combined, but do not break away.

Hereinafter, referring to FIG. 8, secondary leakage of the 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 is performed. The technique for suppressing this will be described in detail.

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

The first inflow path 1IR is formed in the base part 111 in a straight line without being deflected along the advancing direction of the air in the mixing chamber 140, thereby forming a constant step with the inflow end of the air in the mixing chamber 140. The second, third 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 140. Accordingly, the second and third inflow paths 3IR are preferably formed by assembling the base part 111 and the cover part 112.

Here, the second inflow path (2IR) is formed in a direction that reverses the direction of the air in the mixing chamber 140, the flow of the liquid tobacco material compared to the flow of the air can be significantly restricted to prevent the back flow .

In addition, the third inflow path (3IR) is formed toward the inlet end of the air of the mixing chamber 140, when the second inflow path (2IR) is formed in the backward direction, the second inflow path (2IR) It is formed into a structure having a stepped / continuous slope from the end. This may allow the liquid tobacco material leaking from the mixing chamber 140 and accumulated in the inflow path IR of air to be easily re-entered into the mixing chamber 140 by the suction force of the user.

Further, although not shown in the drawing, the third inflow path 3IR is formed toward the inflow end direction of the air in the mixing chamber 140, and has a ring structure, a ring structure, or a spiral structure that is curved along the mixing chamber 140. It may be formed and connected to the mixing chamber 140. The cartridge 100 of the present invention may be in a standing state in a suction operation of a user or in a lying down state or in an inverted state when being carried. Accordingly, the third inflow path 3IR may be a symmetrical ring within a 180 ° range, a ring in a 360 ° range, or a lower portion, which is curved along the circumference of the mixing chamber 140 in consideration of the standing state or the lying down state. Of course, it can be formed of a spiral structure that is narrower in radius.

As described above, the cartridge 100 according to an embodiment of the present invention is a liquid phase through the configuration of the heater 150 including the heat transfer body 152 of the ceramic material and the pressing protrusion 121 of the mouthpiece 120. The leakage of the tobacco material can be primarily reduced, and the leakage of the liquid tobacco material can be secondarily reduced through the refracted inflow path IR formed by the assembly of the base part 111 and the cover part 112. I can alleviate it. In addition, by vaporizing the liquid tobacco material through the heat transfer body 152 of the ceramic material, to prevent the combustion of the wick 142 or the liquid tobacco material due to instantaneous heating to the user harmless to the human body and a rich gaseous phase Tobacco materials can be provided.
