Description

Vaporizer and aerosol-generating device comprising same

Embodiments relate to a vaporizer and an aerosol-generating device having the same, and more particularly, to a vaporizer comprising a valve part that tightly seals and selectively supplies a liquid composition of a liquid storage part and an aerosol-generating device comprising the same. .

In recent years, there is an increasing demand for alternative methods to overcome the shortcomings of common cigarettes. For example, the demand for aerosol-generating methods is increasing as the aerosol-generating material in the cigarette is heated, rather than a method of burning the cigarette to produce an aerosol. Accordingly, research into a heated cigarette or a heated aerosol generating device has been actively conducted.

The aerosol-generating device may include a vaporizer capable of generating an aerosol. The vaporizer may be referred to as, for example, a cartomizer or atomizer, but is not limited thereto. The vaporizer has a liquid reservoir and the liquid composition of the liquid reservoir is absorbed by the wick and heated by the heating. The heating unit may generate an aerosol by heating the liquid composition.

When the user uses the aerosol-generating device, the liquid composition can be provided from the liquid reservoir to the wick. The liquid composition needs to be tightly sealed in the liquid storage portion or in a path through which the liquid composition flows, and needs to be selectively provided to the wick according to the user's use.

If the liquid composition is not tightly sealed in the liquid reservoir or in the path through which the liquid composition flows, leakage may occur where the liquid composition flows out of the aerosol-generating device or other components in the aerosol-generating device. The spilled liquid composition can be spilled out of the vaporizer and delivered to the user. In addition, when the liquid composition is spilled to a component in the aerosol-generating device, it may be inhaled to the user in a liquid state rather than in an aerosol state.

If such leakage occurs repeatedly, the components of the aerosol-generating device may be contaminated, thereby deteriorating the performance of the aerosol-generating device and making the aerosol-generating device impossible to operate. In addition, when the liquid composition is spilled through the airflow inlet of the aerosol-generating device, the user of the aerosol-generating device may feel uncomfortable due to the spilled liquid composition.

3A and 3B showing the valve unit 120 and the wick unit 130 coupled to one side of the valve unit 120, the valve unit 120 and the wick unit 130 can be known in more detail. have. The valve unit 120 that seals the outlet 1101 of the liquid storage unit 110 may be disposed between the liquid storage unit 110 and the wick unit 130. The outlet 1101 of the liquid storage unit 110 may be sealed through the valve unit 120 to prevent the liquid composition from flowing out of the liquid storage unit 110.

The valve portion 120 may include a fixed portion 1201 fixed in position with respect to the liquid storage portion 110 and a deformable portion 1202 disposed adjacent to the fixed portion 1201.

The fixed part 1201 and the deformed part 1202 may have convexly curved faces extending in the direction of the weak part 130 at both end portions. Accordingly, each of the fixing part 1201 and the deforming part 1202 of the valve part 120 may have a ribbon shape in which the central portion protrudes in the direction of the liquid storage part 110, but the fixing part of the valve part 120 ( 1201) and the shape of the deformable portion 1202 is not limited thereto.

The fixing part 1201 of the valve part 120 is fixed in position with respect to the liquid storage part 110, and the deforming part 1202 may be disposed adjacent to the fixing part 1201. At this time, the fixing part 1201 and the deforming part 1202 may be alternately arranged, and the number of the fixing part 1201 and the number of the deforming parts 1202 may correspond to each other.

The valve unit 120 may selectively flow the liquid composition stored in the liquid storage unit 110 to the wick unit 130. When the deformed portion 1202 disposed adjacent to the fixed portion 1201 deforms, a passage may be formed between the fixed portion 1201 and the valve portion 120. The passage may be opened or closed according to the deformation of the deformable portion 1202, through which the liquid composition may flow. The valve unit 120 may block or allow the liquid composition from being supplied to the wick unit 130 from the liquid storage unit 110.

Referring to FIG. 3A, which shows a valve portion 120 of a vaporizer 100 according to an embodiment when the passage is closed, and a wick portion 130 coupled to one side of the valve portion 120, the valve portion ( Each of the portions disposed at positions corresponding to the outlet 1101 of the liquid storage unit 110 among the fixed portion 1201 and the deformed portion 1202 of the 120 is positioned side by side in the same plane, and thus the liquid storage unit 110 The outlet 1101 of the can be sealed.

The surface tension of the liquid composition may act between the fixed portion 1201 and the deformable portion 1202 disposed adjacent to the fixed portion 1201, and the liquid composition is transferred from the liquid storage unit 110 through the surface tension of the liquid composition. Spilling can be prevented.

Referring to FIG. 3B, which shows the valve unit 120 of the vaporizer 100 and the wick unit 130 coupled to one side of the valve unit 120 according to an embodiment when the passage is opened, the valve unit ( The passage formed between the fixed portion 1201 of the 120 and the deformed portion 1202 adjacent to the fixed portion 1201 is one of a direction in which the deformed portion 1202 faces the wick portion 130 and a direction away from the wick portion 130. It can be opened by deforming in one direction.

For example, a portion of the deformed portion 1202 disposed at a position corresponding to the outlet 1101 of the liquid storage portion 110 may be deformed in a direction toward the wick portion 130 according to deflection, but the deformed portion 1202 ) The deformation direction and shape are not limited thereto.

Deformation in one direction of the direction toward the wick portion 130 of the deformable portion 1202 and away from the wick portion 130 may form a passage between the fixing portion 1201 and the deformable portion 1202. The deformable portion 1202 and the fixed portion 1201 may be alternately arranged, and a passage formed between the fixed portion 1201 and the deformable portion 1202 may also be alternately formed in the valve portion 120. The valve unit 120 may allow the liquid composition stored in the liquid storage unit 110 to flow from the liquid storage unit 110 to the wick unit 130 through an open passage.

The passage formed between the fixed portion 1201 and the deformed portion 1202 adjacent to the fixed portion 1201 is the other direction of the direction in which the deformed portion 1202 faces the wick portion 130 and away from the wick portion 130. It can be closed by deformation. For example, a portion of the deformed portion 1202 disposed at a position corresponding to the outlet 1101 of the liquid storage portion 110 is deformed in a direction toward the wick portion 130 as the sag sags, and the valve portion 120 is deformed.

As the passage is closed, the valve unit 120 may block the liquid composition stored in the liquid storage unit 110 from being supplied to the wick unit 130 from the liquid storage unit 110.

The deformable portion 1202 may change according to a change in tensile force acting on the deformed portion 1202. For example, if the magnitude of the tensile force acting on the deformable portion 1202 is reduced, deflection may occur in the deformed portion 1202. Accordingly, a portion of the deformation unit 1202 disposed at a position corresponding to the outlet 1101 of the liquid storage unit 110 may be deformed in a direction toward the weak unit 130.

After the deflection occurs in the deformable portion 1202, if the magnitude of the tensile force acting on the deformed portion 120 increases again, the deformed portion 1202 is disposed at a position corresponding to the outlet 1101 of the liquid storage unit 110 among the deformed portions 1202. The part may be deformed in a direction away from the wick part 130. The deformable portion 1202 may be a material having elasticity.

The wick part 130 may be coupled to one side of the valve part 120, and may absorb a liquid composition flowing through the valve part 120 from the liquid storage part 110. The wick unit 130 may be formed of a material capable of constantly discharging a predetermined amount after absorbing the liquid composition. For example, the wick portion 130 may be formed of at least one of cotton, silica wick, stainless steel mesh and glass fiber, but is not limited to the above-described material. The wick part 130 may be a shape that is coupled to one side of the valve part 120 and surrounds one surface of the valve part 120, and may be a prismatic shape including a cylindrical shape, but the wick part 130 may have a shape. Is not limited thereby.

The vaporizer 100 may include a heating unit 140 for heating the liquid composition absorbed by the wick unit 130. The liquid composition absorbed by the wick 130 may be heated by the heating 140 to generate an aerosol. The aerosol generated in the vaporizer 100 may be delivered to a user and inhaled.

The vaporizer 100 may further include a wick 150 coupled to one side of the wick 130. The wick 150 may be provided with a liquid composition from the wick 130 absorbing the liquid composition from the liquid storage 110. The liquid composition may flow through the wick portion 130 to the wick portion 150, thereby preventing the rapid flow of the liquid composition to the wick portion 150. The liquid composition absorbed by the wick 130 may be moved to the wick 150 and heated by the heating 140. The shape of the wick 150 may be prismatic or cylindrical, but is not limited thereto.

The heating part 140 may generate an aerosol by heating the liquid composition absorbed by the wick part 130 and the wick part 150. The heating unit 140 is located on one side of the wick unit 130 and may be in a shape surrounding the wick unit 150 in contact with one surface of the wick unit 130. The heating unit 140 may have a coil or filament shape, for example, and may be formed to surround the central portion of the wick unit 150. The material of the heating unit 140 may include at least one of nichrome, kanthal, tantalum, stainless, tungsten, nickel, and titanium, but is not limited thereto.

The flow of the liquid composition in the vaporizer 100 can be seen in detail with reference to FIG. 4, which is a diagram schematically showing the vaporizer 100 according to the embodiment when the passage is opened.

The liquid composition may be stored in the liquid storage unit 110 and optionally provided to the wick unit 130. When the liquid composition is stored in the liquid storage unit 110, the liquid composition in the liquid storage unit 110 is transferred to the wick unit 130 by the valve unit 120 that seals the outlet 1101 of the liquid storage unit 110. Supply may be cut off.

The valve unit 120 may selectively provide the liquid composition stored in the liquid storage unit 110 to the wick unit 130. When the deformed portion 1202 disposed adjacent to the fixed portion 1201 deforms, a passage may be formed between the fixed portion 1201 and the valve portion 120. The passage may be opened or closed according to the deformation of the deformable portion 1202. The liquid composition may flow through a passage formed between the fixing part 1201 and the valve part 120. The valve unit 120 may block or allow the liquid composition to be supplied from the liquid storage unit 110 to the wick unit 130 through the fixing unit 1201 and the deformation unit 1202.

The liquid composition that has passed through the valve unit 120 may be absorbed by the wick unit 130 by flowing to the wick unit 130 coupled to one side of the valve unit 120. At this time, the wick portion 130 may absorb the liquid composition that has passed through the valve portion 120 and discharge the absorbed liquid composition again.

The liquid composition may be released from the wick portion 130 and absorbed by the wick portion 150 coupled to one side of the wick portion 130. At this time, the liquid composition is constantly discharged from the wick 130 to prevent the rapid flow of the liquid composition in the vaporizer 100. Accordingly, leakage of the liquid composition outside the vaporizer 100 can also be prevented. have.

The liquid composition absorbed by the wick portion 130 and the wick portion 150 may be heated by the heating portion 140 located between the wick portion 130 and the wick portion 150. As the heating unit 140 heats the liquid composition, an aerosol may be generated in the vaporizer 100. The aerosol generated in the vaporizer 100 may be discharged from the vaporizer 100 and sucked by the user.

The vaporizer 100 may further include an airflow path 250 that is connected to the vaporizer 100 and discharges an aerosol in the vaporizer 100.

In addition, the aerosol-generating device 200 may have an air inlet 205 through which external air can be introduced, and a cigarette may be inserted into the inner space of the aerosol-generating device 200.

It can be understood by those of ordinary skill in the art related to this embodiment that other general-purpose components in addition to those shown in FIG. 5 may be further included in the aerosol-generating device 200.

In addition, although the heater 240 is illustrated in the aerosol generating device 200 in FIG. 5, the heater 240 may be omitted, if necessary. Depending on the design of the aerosol-generating device 200, the arrangement of the battery 230, the control unit 220, the sensor 210, the vaporizer 100, and the heater 240 may be changed.

The sensor 210 may detect smoking of the user. The sensor 210 detects, for example, a drop in pressure in the aerosol-generating device 200 due to the user's smoking, a temperature change in the aerosol-generating device 200, or an air flow in the aerosol-generating device 200, and the like. Can detect smoking. The sensor 210 may be a puff detection sensor 210, a temperature detection sensor 210, etc., but the operating principle and type of the sensor 210 are not limited thereto.

Although the sensor 210 of the aerosol-generating device 200 is illustrated as being included inside the aerosol-generating device 200 in FIG. 5, it may be mounted on an outer surface or a case coupled with the outer surface of the aerosol-generating device 200. .

The control unit 220 controls the operation of the aerosol generating device 200. Specifically, the control unit 220 controls the operation of the batteries 230, the heater 240, and the vaporizer 100, as well as other components included in the aerosol-generating device 200.

The control unit 220 includes at least one processor. The processor may be implemented as an array of multiple logic gates, or may be implemented as a combination of a general-purpose microprocessor and a memory in which programs executable on the microprocessor are stored. In addition, those of ordinary skill in the art to which this embodiment pertains may understand that it may be implemented in other types of hardware.

The control unit 220 may check the state of each of the components of the aerosol generating device 200 to determine whether the aerosol generating device 200 is in an operable state. In addition, by controlling the operation of the valve unit 120 and the heating unit 140 in the vaporizer 100, the control unit 220 may generate an aerosol in the vaporizer 100.

The vaporizer 100 may generate an aerosol by heating the liquid composition, and the aerosol generated in the vaporizer 100 may be delivered to a user through a cigarette. The aerosol-generating device 200 may include an airflow pass 250 through which the aerosol generated in the vaporizer 100 flows.

The aerosol generated by the vaporizer 100 may move along the airflow path 250 of the aerosol-generating device 200, and the airflow path 250 passes through the cigarette by the aerosol generated by the vaporizer 100. It can be configured to be delivered to the user.

The vaporizer 100 may include a liquid storage unit 110, a valve unit 120, a wick unit 130, and a heating unit 140, but is not limited thereto. For example, the liquid storage unit 110, the valve unit 120, the wick unit 130, and the heating unit 140 may be included in the aerosol generating device 200 as independent modules.

If the liquid composition is heated in the vaporizer 100 of the aerosol-generating device 200 to learn in detail about the process of generating the aerosol, the user's smoking by the sensor 210, that is, the use of the aerosol-generating device 200 Upon detection, the control unit 220 of the aerosol generating device 200 may transmit an electrical signal to the vaporizer 100. The electrical signal of the control unit 220 is transmitted to the vaporizer 100 and the deformable portion 1202 of the valve portion 120 of the vaporizer 100 may be deformed.

At this time, the deformable portion 1202 may open a passage of the valve portion 120 by deforming in one direction of a direction toward the wick portion 130 and a direction away from the wick portion 130. As the passage of the valve part 120 is opened, the liquid composition stored in the liquid storage part 110 may be supplied from the liquid storage part 110 to the weak part 130.

In addition, according to the electrical signal of the control unit 220, the heating unit 140 of the vaporizer 100 is operated to increase the temperature of the heating unit 140. When the heating part 140 heats the liquid composition absorbed by the wick part 130 and the wick part 150, an aerosol may be generated in the vaporizer 100. At this time, the aerosol generated by the vaporizer 100 may be delivered to the user through the airflow path 250 connected from the vaporizer 100 to the outside of the aerosol-generating device 200. Alternatively, when a cigarette is inserted into the aerosol-generating device 200, the aerosol that has passed through the airflow path 250 may further pass through the cigarette and be delivered to the user.

When the user stops using the aerosol-generating device 200, the passage of the valve unit 120 of the vaporizer 100 may be closed again. At this time, the deformable portion 1202 of the valve portion 120 may close the passage of the valve portion 120 by deforming it in another direction of the direction toward the wick portion 130 and away from the wick portion 130. As the passage is closed, supply of the liquid composition to the weak portion 130 may be blocked.

In addition, the operation of the heating unit 140 in the vaporizer 100 may be stopped to lower the temperature of the heating unit 140. Accordingly, aerosol generation in the vaporizer 100 can be prevented and power consumption of the aerosol generating device 200 can be prevented from being wasted.

The heater 240 may be heated by electric power supplied from the battery 230. For example, when the cigarette is inserted into the aerosol-generating device 200, the heater 240 may be located inside the cigarette. Thus, the heated heater 240 can increase the temperature of the aerosol-generating material in the cigarette.

The heater 240 may be an electric resistive heater 240. For example, the heater 240 may include an electrically conductive track, and as the current flows through the electrically conductive track, the heater 240 may be heated. However, the heater 240 is not limited to the above-described example, and may be applied without limitation as long as it can be heated to a desired temperature. Here, the desired temperature may be previously set in the aerosol-generating device 200, or may be set to a desired temperature by the user.

Meanwhile, as another example, the heater 240 may be an induction heating heater 240. Specifically, the heater 240 may include an electrically conductive coil for heating the cigarette in an induction heating method, and the cigarette may include a susceptor capable of being heated by the induction heating method 240.

Meanwhile, the aerosol-generating device 200 may further include general-purpose components in addition to the battery 230, the control unit 220, and the heater 240. For example, the aerosol generating apparatus 200 may include a display capable of outputting visual information and / or a motor for outputting tactile information.
