1 is a diagram showing an aerosol generating device according to an embodiment.

Referring to FIG. 1 , an aerosol generating device 100 according to an embodiment may include a first chamber 110, a second chamber 120, a discharge passage 130, and a sieve 140. Components related to the present embodiment are shown in the aerosol generating device 100 shown in FIG. 1 . Therefore, those of ordinary skill in the art related to the present embodiment may understand that other general-purpose components other than the components shown in FIG. 1 may be further included in the aerosol generating device 100.

The first chamber 110 may be a space in which an aerosol-generating material accommodated therein changes into an aerosol. The first chamber 110 may include a first storage tank 111 , a first valve 112 , a first elastic part 113 , and a first support part 114 .

The first storage tank 111 may store the first aerosol generating material. For example, the first storage tank 111 may store the first aerosol generating material by accommodating the first aerosol generating material therein.

As an example, the first aerosol generating material stored inside the first storage tank 111 may be in a pressurized fluid state. Accordingly, the first aerosol generating material is stored in a pressurized state inside the first storage tank 111, and when the first storage tank 111 is opened, due to the high pressure inside the first storage tank 111 May be released in the form of an aerosol.

Here, the pressurized fluid may refer to a fluid compressed to a pressure higher than atmospheric pressure, and the expression may be used equally below unless otherwise noted.

For example, the first aerosol generating material may be stored inside the first storage tank 111 in a pressurized state at a pressure of 3 atm to 150 atm. Preferably, the first aerosol generating material may be stored inside the first storage tank 111 in a pressurized state at a pressure of 5 to 20 atm, but is not limited thereto, and the first aerosol generating material may be stored in various pressure ranges. can be pressurized.

The first aerosol generating material may include at least one of a tobacco-containing material including a volatile tobacco flavor component, a non-tobacco material, oxygen, carbon dioxide, and nitrogen. For example, the first storage tank 111 may include an amount of oxygen corresponding to 30% to 70% of the internal volume of the first storage tank 111, but is not limited thereto.

The first aerosol-generating substance may include, for example, any one of water, solvents, ethanol, plant extracts, fragrances, flavors, and vitamin mixtures, or mixtures of these components. Fragrance may include menthol, peppermint, spearmint oil, various fruit flavor components, etc., but is not limited thereto. Flavoring agents can include ingredients that can provide a variety of flavors or flavors to the user. The vitamin mixture may be a mixture of at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but is not limited thereto. The first aerosol generating material may also include aerosol formers such as glycerin and propylene glycol.

For example, the first aerosol generating material may comprise a solution of glycerin and propylene glycol in any weight ratio to which a nicotine salt has been added. The first aerosol generating material may include two or more nicotine salts. Nicotine salts can be formed by adding a suitable acid, including organic or inorganic acids, to nicotine. The nicotine may be naturally occurring nicotine or synthetic nicotine, which may be in any suitable weight concentration relative to the total weight of the solution of the first aerosol generating material.

The acid for forming the nicotine salt may be appropriately selected in consideration of the absorption rate of nicotine in the blood, the operating temperature of the aerosol generating device 100, flavor or taste, solubility, and the like. For example, acids for the formation of nicotine salts include benzoic acid, lactic acid, salicylic acid, lauric acid, sorbic acid, levulinic acid, pyruvic acid, formic acid, acetic acid, propionic acid, butyric acid, valeric acid, caproic acid, caprylic acid, capric acid , citric acid, myristic acid, palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, phenylacetic acid, tartaric acid, succinic acid, fumaric acid, gluconic acid, saccharic acid, malonic acid, or a single acid selected from the group consisting of malic acid or the above It may be a mixture of two or more acids selected from the group, but is not limited thereto.

As an example, the first storage tank 111 may be detachably coupled to the aerosol generating device 100 . Accordingly, when the first aerosol generating material inside the first storage tank 111 is exhausted, the first storage tank 111 may be replaced.

As another example, when the first aerosol generating material inside the first storage tank 111 is exhausted, the first storage tank 111 may be charged with the first aerosol generating material from the outside.

The first storage tank 111 may include a discharge hole 111a. For example, the discharge hole 111a may be a passage through which the first aerosol generating material in a pressurized fluid state is ejected in an aerosol state when the first storage tank 111 is opened.

The first valve 112 may open or close the first storage tank 111 . As an example, the first valve 112 may close the first storage tank 111 by being disposed to cover the discharge hole 111a of the first storage tank 111 .

Here, closing may mean that the first valve 112 hermetically seals the first storage tank 111 to make it impossible for the fluid to be discharged from the first storage tank 111, and the corresponding expression hereinafter may be used in the same meaning unless otherwise stated.

As another example, the first valve 112 may open the first storage tank 111 in response to the user's suction pressure. Specifically, the first valve 112 may open the first storage tank 111 by moving in a direction away from the first storage tank 111 (eg, +z direction in FIG. 1) by the user's suction pressure. can

Here, the suction pressure may refer to the pressure applied by the user to the aerosol generating device 100 in order to inhale the aerosol, and the corresponding expression may be used in the same meaning below unless otherwise noted.

The first elastic part 113 may provide elastic force to press the first valve 112 by being compressed or stretched. For example, the first elastic part 113 is directed toward the first storage tank 111, which is opposite to the direction in which the pressurized fluid inside the first storage tank 111 presses the first valve 112. (eg, the first valve 112 may be pressed in the -z direction of FIG. 1). Accordingly, the first elastic part 113 may maintain a state in which the first valve 112 closes the first storage tank 111 .

The elastic force with which the first elastic part 113 presses the first valve 112 may determine the suction resistance of the aerosol generating device 100 . Specifically, the user can inhale the aerosol by opening the first storage tank 111 by providing the aerosol generating device 100 with a suction pressure capable of overcoming the suction resistance of the first elastic part 113.

Here, the suction resistance may mean the pressure required for the user to inhale the aerosol from the aerosol generating device 100, and the expression may be used in the same meaning unless otherwise specified.

In addition, after the first valve 112 is opened in response to the user's suction pressure, the first elastic part 113 allows the first valve 112 to close the first storage tank 111 again. 112) may provide a restoring force for restoring the position.

For example, the first elastic part 113 may be a spring, but is not limited thereto, and various elastic bodies conforming to Hooke's Law may be employed.

The first support part 114 may be disposed inside the first chamber 110 and support the first elastic part 113 . For example, one end of the first elastic part 113 may be connected to the first valve 112 and the other end of the first elastic part 113 may be connected to the first support part 114 .

The first support part 114 may be disposed to be movable inside the first chamber 110 . In addition, the first support part 114 may provide a reference point at which the first elastic part 113 is compressed or stretched by fixing its position inside the first chamber 110 before the user starts inhaling. . However, a detailed description thereof will be described later.

The second chamber 120 may include a second storage tank 121 , a second valve 122 , a second elastic part 123 , and a second support part 124 .

Meanwhile, the second storage tank 121 is connected to the first storage tank 111, the second valve 122 is connected to the first valve 112, and the second elastic part 123 is connected to the first elastic part 113. , The second support portion 124 may be substantially the same as the first support portion 114, and therefore, overlapping descriptions will be omitted.

The second storage tank 121 may store a second aerosol generating material different from the first aerosol generating material. Specifically, the second aerosol generating material is stored in the second storage tank 121 in a pressurized fluid state similar to the first aerosol generating material, but may contain different components or have different composition ratios.

As an example, the second aerosol generating material may include a different fragrance than the first aerosol generating material. Accordingly, each of the aerosols generated from the fragrance included in the first aerosol generating material or the second aerosol generating material may be combined with each other to provide a new flavor to the user or serve as an enhancer that enhances either flavor. there is.

As another example, the second aerosol generating material may be classified according to whether it contains the first aerosol generating material and nicotine, but is not limited by the foregoing description.

The second valve 122 may open or close the second storage tank 121 . Specifically, the second valve 122 may open the second storage tank 121 in response to a user's suction pressure different from the user's suction pressure at which the first valve 112 is opened.

For example, the second valve 122 may open the second storage tank 121 in response to a user's suction pressure lower than the user's suction pressure at which the first valve 112 is opened. Accordingly, the second valve 122 may open before the first valve 112 when the user inhales the aerosol.

The second elastic part 123 may provide elastic force to press the second valve 122 by being compressed or stretched. Specifically, the second elastic part 123 may provide the second valve 122 with an elastic force different from the elastic force with which the first elastic part 113 presses the first valve 112 .

For example, the modulus of elasticity of the second elastic part 123 and the modulus of elasticity of the first elastic part 113 may be different from each other. Accordingly, the first valve 112 and the second valve 122 may be opened in response to different suction pressures of users.

The second elastic part 123 may be, for example, a spring, but is not limited thereto, and various elastic bodies conforming to Hooke's Law may be employed.

The second support part 124 may be disposed inside the second chamber 120 and support the second elastic part 123 . For example, one end of the second elastic part 123 may be connected to the second valve 122 and the other end of the second elastic part 123 may be connected to the second support part 124 .

The discharge passage 130 may be a passage through which aerosol discharged from at least one of the first storage tank 111 and the second storage tank 121 is discharged to the outside of the aerosol generating device 100 . For example, one end of the discharge passage 130 communicates with at least one of the first chamber 110 and the second chamber 120, and the other end of the discharge passage 130 is outside the aerosol generating device 100. can be connected with

Among the aerosols passing through the discharge passage 130, the sieve 140 may capture aerosols having a size greater than a predetermined size. Specifically, the strainer 140 may include a plurality of perforations and pass only aerosols smaller than the perforations, thereby capturing aerosols larger than the perforations 140a.

The user of the aerosol-generating device 100 can comfortably inhale the aerosol as the strainer 140 captures the aerosol having large particles that may be objectionable to the user.

For example, the strainer 140 may be in the form of a mesh including perforations 140a having a size of 3 μm to 50 μm, but is not limited thereto.

Meanwhile, the same reference numerals for components of the embodiments shown in FIG. 1 may mean substantially the same components hereinafter, and components for one embodiment may be substantially equally applied to other embodiments. there is.

FIG. 2 is a diagram illustrating another aspect of the aerosol-generating device shown in FIG. 1; More specifically, FIG. 2 is a view showing a state in which the second valve 122 of the aerosol generating device 100 shown in FIG. 1 is opened.

Referring to FIG. 2 , the first elastic part 113 and the second elastic part 123 may have different modulus of elasticity. As an example, the modulus of elasticity of the first elastic part 113 may be greater than that of the second elastic part 123 . In this case, the pressure applied to the first valve 112 by the first elastic part 113 may be greater than the pressure applied to the second valve 122 by the second elastic part 123 .

In a state before the user inhales the aerosol, the second valve 122 may keep the second storage tank 121 closed by the second elastic part 123 . In other words, since the pressure applied to the second valve 122 by the second elastic part 123 is greater than the pressure applied to the second valve 122 by the pressurized fluid inside the second storage tank 121, the second valve (122) may keep the second storage tank 121 closed.

A user may apply suction pressure to the aerosol generating device 100 to inhale the aerosol. The user's suction pressure may apply pressure to the second valve 122 in a direction away from the second storage tank 121 .

Accordingly, when the sum of the user's suction pressure and the pressure applied by the pressurized fluid inside the second storage tank 121 is greater than the pressure applied by the second elastic part 123, the second valve 122 2 can move in a direction away from the storage tank 121.

When the second valve 122 moves in a direction away from the second storage tank 121, the second storage tank 121 is opened, and the second aerosol generating material accommodated in the second storage tank 121 is an aerosol. It is ejected in the state and can pass through the discharge passage 130. The aerosol passing through the discharge passage 130 may be discharged to the outside of the aerosol generating device 100 and reach the user.

On the other hand, since the suction resistance of the first elastic part 113 is greater than the suction resistance of the second elastic part 123, the first valve 112 is opened by the suction pressure by which the second valve 122 is opened. It may not be. In other words, since the pressure applied to the first valve 112 by the first elastic part 113 is greater than the pressure applied to the second valve 122 by the second elastic part 123, unlike the second valve 122 The first valve 112 may keep the first storage tank 111 closed.

However, when the user's suction pressure increases and the sum of the user's suction pressure and the pressure applied by the pressurized fluid inside the first storage tank 111 is greater than the pressure applied by the first elastic part 113, 1 valve 112 may move in a direction away from the first storage tank 111 .

When the first storage tank 111 is opened by moving the first valve 112, the first aerosol generating material accommodated in the first storage tank 111 may be ejected in an aerosol state. In addition, the ejected aerosol may pass through the discharge passage 130 and reach the user.

As described above, in the aerosol generating device 100 according to an embodiment, whether the first storage tank 111 or the second storage tank 121 is opened may differ depending on the user's suction pressure. Accordingly, since the user can inhale different types of aerosols or inhale aerosols in the form of a combination of different types of aerosols according to the suction pressure, the aerosol generating device 100 according to an embodiment provides the user with discriminating aerosols. Smoking can give satisfaction.

Meanwhile, the following description is based on the first chamber 110, but the embodiment applied to the first chamber 110 can be substantially equally applied to the second chamber 120. It will be obvious to those skilled in the art.

FIG. 3A is a diagram showing an aerosol generating device according to another embodiment, and FIG. 3B is a diagram showing another aspect of the aerosol generating device shown in FIG. 3A.

3A and 3B, the aerosol generating device 100 according to another embodiment includes a first storage tank 111, a first valve 112, a first elastic part 113, and a first support part 114. , a protrusion 115, a central axis 116, and a through hole 117 may be included.

The protrusion 115 may be moved by the first valve 112 to notify the user that the first storage tank 111 is opened. For example, at least a portion of the protrusion 115 protrudes to the outside of the aerosol generating device 100 by being rotated by the first valve 112, and the user can see the first storage tank 111 through the protrusion 115. It can be seen that it is open.

The central axis 116 may provide a rotational center of the protrusion 115 . For example, the central axis 116 may pass through the protrusion 115 , and the protrusion 115 may rotate about the central axis 116 .

The through hole 117 may be disposed adjacent to the protrusion 115 . Accordingly, the protrusion 115 rotated by the first valve 112 may pass through the through hole 117 and protrude out of the aerosol generating device 100 .

A user may apply suction pressure to the aerosol generating device 100 to inhale the aerosol. The user's suction pressure may apply pressure to the first valve 112 in a direction away from the first storage tank 111 .

Accordingly, when the sum of the user's suction pressure and the pressure applied by the pressurized fluid inside the first storage tank 111 is greater than the pressure applied by the first elastic part 113, the first valve 112 1 can move in a direction away from the storage tank 111.

When the first storage tank 111 is opened by moving the first valve 112, the first aerosol generating material accommodated in the first storage tank 111 may be ejected in an aerosol state.

In addition, when the first valve 112 moves in a direction away from the first storage tank 111, the first valve 112 moves away from the first storage tank 111 at one end 115a of the protrusion 115. A force acting in one direction can be applied. Accordingly, the protrusion 115 may rotate in the first rotational direction around the central axis 116, and the other end 115b of the protrusion 115 may protrude out of the aerosol generating device 100.

Here, the first rotation direction is the direction in which the protrusion 115 rotates so that the other end 115b of the protrusion 115 protrudes out of the aerosol generating device 100 (eg, y in FIGS. 3A and/or 3B). A rotation direction in a counterclockwise direction using the axis as a rotation axis).

As another example, as the user's inhalation ends, the first valve 112 may move in a direction toward the first storage tank 111 . The weight of one end 115a of the protrusion 115 may be greater than the weight of the other end 115b of the protrusion 115 .

Since the weight of one end 115a of the protrusion 115 is greater than the weight of the other end 115b of the protrusion 115, when the user's inhalation ends, the protrusion 115 may rotate in the second rotational direction. Accordingly, the protruding portion 115 may be restored to a position of a state before the first valve 112 is opened.

Here, the second rotation direction is the direction in which the protrusion 115 rotates so that the other end 115b of the protrusion 115 is positioned inside the aerosol generating device 100 (eg, y in FIGS. 3A and/or 3B). clockwise rotation direction with the axis as the rotation axis).

As described above, the aerosol generating device 100 according to another embodiment may visually notify the user that the first storage tank 111 is opened according to the user's suction pressure through the protrusion 115.

Accordingly, when the protrusion 115 is included inside the first chamber 110 and the second chamber 120, the user inhales the aerosol in the first storage tank 111 or the second storage tank 121. It is possible to visually confirm which storage tank it is ejected from.

FIG. 4A is a view showing an aerosol generating device according to another embodiment, and FIG. 4B is a view showing the outside of the aerosol generating device shown in FIG. 4A.

4A and 4B, the aerosol generating device 100 according to another embodiment includes a first storage tank 111, a first valve 112, a first elastic part 113, and a first support part 114. ), a knob 150, a guide groove 160, a sealing member 170, an installation hole 180, and a fixing part 190.

The first support part 114 may be disposed to be movable inside the first chamber 110 . For example, the first support 114 may move toward the first valve 112 or away from the first valve 112 .

As the first support part 114 moves, the distance between the first valve 112 and the first support part 114 changes so that the length of the first elastic part 113 changes, and the first elastic part 113 ) may change the pressure at which the first valve 112 is pressed.

The knob 150 may be exposed to the outside of the aerosol generating device 100 . For example, the knob 150 extends from the first support 114 to protrude out of the aerosol generating device 100 and can move together with the first support 114 . Accordingly, the user may change the position of the first support part 114 by using the knob 150 from the outside of the aerosol generating device 100 .

The guide groove 160 may guide the movement of the knob 150 . For example, the guide groove 160 may be formed along the longitudinal direction (eg, the +z or -z direction of FIG. 6 ) of the aerosol generating device 100 . Accordingly, the knob 150 may slide with respect to the outer surface 100a of the aerosol generating device 100 along the guide groove 160 .

The sealing member 170 may prevent the aerosol from leaking unnecessarily from the first chamber 110 to the outside of the aerosol generating device 100 . For example, the sealing member 170 may be disposed between the outer surface 100a of the aerosol generating device 100 and the first support 114 .

A plurality of installation holes 180 may be disposed on the outer surface 100a of the aerosol generating device 100 along the longitudinal direction of the aerosol generating device 100 . For example, the installation hole 180 may have a shape in which a plurality of hollow holes are perforated on the outer surface of the aerosol generating device 100.

The fixing part 190 may limit the movement of the first support part 114 . The user may move the first support part 114 to a desired location and fix the position of the first support part 114 using the fixing part 190 . For example, the fixing part 190 may limit the movement of the knob 150 by penetrating at least a portion of the knob 150 and combining with the installation hole 180 .

A method of fixing the position of the first support part 114 by the fixing part 190 is not limited by the foregoing and may be changed in various ways. For example, the fixing part 190 is formed along the guide groove 160 and includes a plurality of grooves having a shape corresponding to the knob 150, and the knob 150 is accommodated in the grooves to form a first support part ( 114) may be fixed.

FIG. 5A is a diagram showing another aspect of the aerosol generating device shown in FIG. 4A and FIG. 5B is a diagram showing another aspect of the aerosol generating device shown in FIG. 4 . More specifically, the aerosol generating device 100 of FIGS. 5A and 5B may be in a state in which the first elastic part 113 is compressed more than the aerosol generating device 100 of FIGS. 4A and 4B.

The user's suction pressure required to open the first storage tank 111 may be proportional to the pressure applied to the first valve 112 by the first elastic part 113 . Accordingly, the pressure required to open the first storage tank 111 by changing the length of the first elastic part 113 by changing the position of the first support part 114 before the user inhales the aerosol. can be changed.

For example, when the first support part 114 is disposed adjacent to the discharge passage 130, the first elastic part 113 may be in an elastic equilibrium state. Here, the elastic equilibrium state may mean a state in which no elastic restoring force acts on the elastic body because the elastic body is not deformed.

When the first support part 114 moves in a direction toward the first valve 112, the first elastic part 113 is compressed and the pressure applied to the first valve 112 by the first elastic part 113 increases. can Accordingly, the pressure required to open the first storage tank 111 may increase.

In addition, the user fixes the position of the first support part 114 by moving the first support part 114 to a specific position and coupling the fixing part 190 to the installation hole 180 in order to set a desired suction pressure. can make it

As another example, when the first support part 114 moves in a direction away from the first valve 112 again in a state in which the first elastic part 113 is compressed, the first elastic part 113 is stretched so that the first elastic part 113 is stretched. Pressure applied to the first valve 112 by the unit 113 may decrease. Accordingly, the pressure required to open the first storage tank 111 may decrease.

As described above, the aerosol generating device 100 according to another embodiment utilizes the first support 114 to adjust the pressure at which the first storage tank 111 is opened, so that the user inhales the aerosol. Suction pressure can be adjusted. Accordingly, the aerosol generating device 100 may provide a differentiated smoking satisfaction to the user by allowing the user to experience various resistances to drawing.

6A is a diagram showing an aerosol generating device according to another embodiment.

Referring to FIG. 6A, the aerosol generating device 100 according to another embodiment includes a first storage tank 111, a first valve 112, a first elastic part 113, a first support part 114, a knob 150, a guide groove 160, a sealing member 170, an installation hole 180, and a fixing part 190 may be included.

The first elastic part 113 may include a plurality of elastic members. Also, each of the plurality of elastic members may have different lengths. Here, the length of the elastic member may mean a length extending from the first support part 114 toward the first valve 112, and the expression may be used the same below unless otherwise noted.

Meanwhile, although the number of elastic members included in the first elastic part 113 is shown as two in FIG. 6A, the number of elastic members may be changed as needed without being limited thereto.

As an example, the first elastic member 113 includes a first elastic member 113a and a second elastic member 113b, and the length of the first elastic member 113a is the length of the second elastic member 113b. can be longer

Accordingly, in a state where the first support part 114 is disposed adjacent to the discharge passage 130, the first elastic member 113a is disposed to come into contact with the first valve 112 to press the first valve 112. And, the second elastic member (113b) is spaced apart from the first valve 112 may not pressurize the first valve (112).

Meanwhile, the user's suction pressure required to open the first storage tank 111 may be proportional to the pressure applied to the first valve 112 by the first elastic part 113 . Accordingly, in a state before the user inhales the aerosol, the position of the first support part 114 is changed to change the number of elastic members that press the first valve 112 to open the first storage tank 111. You can adjust the pressure you need.

FIG. 6B is a diagram illustrating another aspect of the aerosol generating device shown in FIG. 6A. More specifically, the aerosol generating device 100 of FIG. 6B may be in a state in which the number of elastic members of the first elastic part 113 pressing the first valve 112 is increased compared to the aerosol generating device 100 of FIG. 6A. there is.

Referring to FIG. 6B, as the first support part 114 moves in the direction toward the first valve 112, the distance between the first support part 114 and the first valve 112 decreases, thereby increasing the second elasticity. The member 113b and the first valve 112 may be disposed to be in contact with each other.

Accordingly, the number of elastic members that press the first valve 112 increases, so that the pressure applied to the first valve 112 by the first elastic part 113 increases, thereby opening the first storage tank 111. The pressure required for this may increase.

In addition, as the first support part 114 moves in a direction away from the first valve 112, the distance between the first support part 114 and the first valve 112 increases, so that the second elastic member 113b ) and the first valve 112 may be spaced apart again.

As described above, the aerosol generating device 100 according to another embodiment utilizes the first support part 114 to change the number of elastic members that press the first valve 112 so that the first storage tank 111 The opening pressure can be adjusted. Accordingly, the aerosol generating device 100 may provide a differentiated smoking satisfaction to the user by allowing the user to experience various resistances to drawing.

Those skilled in the art related to the present embodiment will be able to understand that it may be implemented in a modified form within a range that does not deviate from the essential characteristics of the above description. Therefore, the disclosed methods are to be considered in an illustrative rather than a limiting sense. The scope of the present invention is shown in the claims rather than the foregoing description, and all differences within the equivalent range should be construed as being included in the present invention.
