Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, specifically to a liquid storage bottle and an atomizer. Background Technology

[0002] An atomizer is a device that uses a heating element to heat an aerosol-generating matrix to form an aerosol. In related technologies, an atomizer has a reservoir and a reservoir bottle. The heating element is located inside the reservoir, and the reservoir bottle stores the aerosol-generating matrix. The reservoir bottle continuously feeds the aerosol-generating matrix into the reservoir to replenish it. When the atomizer is inverted, the reservoir bottle typically replenishes the reservoir with an excessive amount of aerosol-generating matrix, increasing the risk of leakage. Utility Model Content

[0003] This application provides a liquid storage bottle and an atomizer to solve or partially solve the technical problem of leakage when the atomizer with the liquid storage bottle is inverted.

[0004] In some embodiments, a liquid storage bottle is provided, comprising a bottle body and a switch valve. The bottle body has a bottle opening, and the bottle body has a first chamber and a second chamber separated from each other. The first chamber is used to contain an atomized matrix, and the second chamber is in communication with the bottle opening. The switch valve is located between the second chamber and the first chamber and is configured to control the communication or non-communication between the first chamber and the second chamber.

[0005] In some embodiments, the bottle body is provided with a partition, which is configured to divide the inner cavity of the bottle body into a first chamber and a second chamber. The partition has a liquid inlet, and the switch valve is located at the liquid inlet. The liquid inlet is located at the end of the second chamber away from the bottle opening.

[0006] In some embodiments, the switching valve includes a movable member and an elastic member, the movable member being configured to open the inlet under the action of an external force, and the elastic member having elastic potential energy that causes the movable member to block the inlet; when the inlet is in the open state, the first chamber and the second chamber are connected through the inlet; when the inlet is in the blocked state, the first chamber and the second chamber are not connected.

[0007] In some embodiments, the movable component has a channel, the first opening of the channel is located on the end face of the movable component facing the bottle opening, and the second opening of the channel is located on the side wall of the movable component; when the liquid inlet is in the open state, the first chamber, the second opening, the channel, the first opening, and the second chamber are connected in sequence; when the liquid inlet is in the blocked state, the first chamber and the second opening are not connected.

[0008] In some embodiments, multiple second openings are provided, and the multiple second openings are spaced apart around the outer periphery of the movable member.

[0009] In some embodiments, the movable member is configured such that, in the open state, the second opening enters the first chamber along with the movable member.

[0010] In some embodiments, the switching valve further includes a first seal connected to the end of the movable member opposite to the bottle opening, the first seal being configured to seal the gap between the movable member and the bottle opening when the inlet is in a blocked state.

[0011] In some embodiments, the bottle body includes a first housing and a first bottom cover, the first housing having the bottle opening, and one end of the first housing opposite to the bottle opening being connected to the first bottom cover; the liquid storage bottle also includes a second sealing member, the second sealing member being connected to the first housing and the first bottom cover respectively to seal the gap between the first housing and the first bottom cover.

[0012] In some embodiments, an atomizer is also provided, which includes a liquid storage chamber, a liquid storage bottle as described above, a bracket, and a liquid guiding element. The bracket is fixedly connected to the liquid storage chamber, and a support portion is provided on the side of the bracket away from the liquid storage chamber. The support portion is inserted into the second chamber and abuts against the switch valve. The liquid guiding element is connected to the bracket, with one end inserted into the second chamber and the other end inserted into the inner cavity of the liquid storage chamber.

[0013] In some embodiments, the support includes a first through hole, a second through hole, and a vent. One end of the first through hole is located on the end face of the support portion and communicates with the first opening of the channel in the switching valve. One end of the second through hole communicates with the first through hole, and the other end communicates with the inner cavity of the liquid storage tank. Along the radial direction of the second through hole, the diameter of the second through hole is smaller than the diameter of the first through hole. The liquid guiding element passes through the first through hole and the second through hole. A plurality of vents are arranged around the outer periphery of the second through hole, one end of the vent communicates with the first through hole, and the other end of the vent communicates with the inner cavity of the liquid storage tank.

[0014] In some embodiments, the atomizer further includes a third seal disposed between the side wall of the support and the wall of the second chamber.

[0015] According to the above embodiment, the switching valve of the storage bottle is configured to control the connection or disconnection between the first chamber and the second chamber. When the first chamber and the second chamber are not connected, the aerosol generating matrix in the first chamber will not flow into the second chamber, and the storage bottle will not leak. When the first chamber and the second chamber are connected, since the switching valve is located at the end of the second chamber away from the bottle opening, that is, the connection position between the second chamber and the first chamber is close to the bottom of the storage bottle, when the storage bottle is upright, the aerosol generating matrix in the first chamber will flow out and enter the second chamber, and the storage bottle can provide aerosol generating matrix for the storage chamber in the atomizer. When the storage bottle is inverted, the height of the aerosol generating matrix is ​​lower than the connection position between the second chamber and the first chamber, and the aerosol generating matrix in the first chamber will not flow out. Therefore, the storage bottle is also less likely to leak when inverted, reducing the risk of leakage when the atomizer is inverted. Attached Figure Description

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0036] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0037] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, the terms "connection" and "linkage" used in this application include both direct and indirect connections.

[0038] Atomizers can be placed in various positions, such as upright or inverted. In current technology, when atomizers are inverted, the aerosol-generating matrix inside the e-liquid bottle continuously leaks out, causing the reservoir to replenish the reservoir with excessive amounts of aerosol-generating matrix, leading to a tendency for leakage.

[0039] Reference Figures 1 to 13 This application provides a liquid storage bottle 1 and an atomizer. When inverted, the aerosol generating matrix will not flow out of the liquid storage bottle 1, and the liquid storage bottle 1 will not replenish the liquid storage chamber 3 with excessive aerosol generating matrix, thereby reducing the risk of leakage of the atomizer.

[0040] The liquid storage bottle 1 and the atomizer provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0041] In some embodiments, the storage bottle 1 includes a bottle body 11 and a switching valve 2. The bottle body 11 has a bottle opening 12, and a first chamber 13 and a second chamber 14 separated from each other are formed inside the bottle body 11. The first chamber 13 is used to contain the atomized matrix, and the second chamber 14 is connected to the bottle opening 12. The switching valve 2 is located between the first chamber 13 and the second chamber 14. The switching valve 2 is located at the end of the second chamber 14 away from the bottle opening 12 and is configured to control the connection or disconnection between the first chamber 13 and the second chamber 14.

[0042] The first chamber 13 and the second chamber 14 of this application extend along the height direction of the liquid storage bottle 1, that is... Figure 4 The direction indicated by the middle arrow Z is also the height direction of the atomizer. In the height direction, one end of the second chamber 14 is connected to the bottle opening 12, and the other end, near the bottom 114 of the bottle, is equipped with a switch valve 2. The connection point between the second chamber 14 and the first chamber 13 is close to the bottom 114 of the liquid storage bottle 1.

[0043] In this embodiment of the application, the liquid storage bottle 1 has a switch valve 2 configured to control the connection or disconnection between the first chamber 13 and the second chamber 14. When the first chamber 13 and the second chamber 14 are not connected, the aerosol generation matrix in the first chamber 13 will not flow into the second chamber 14, and the liquid storage bottle 1 will not leak. When the first chamber 13 and the second chamber 14 are connected, since the switch valve 2 is located at the end of the second chamber 14 away from the bottle opening 12, that is, the connection position between the second chamber 14 and the first chamber 13 is close to the bottom 114 of the storage bottle 1, when the storage bottle 1 is upright, the aerosol generating matrix in the first chamber 13 will flow out and enter the second chamber 14. The storage bottle 1 can provide the aerosol generating matrix for the storage chamber in the nebulizer. When the storage bottle 1 is inverted, the height of the aerosol generating matrix is ​​lower than the connection position between the second chamber 14 and the first chamber 13, and the aerosol generating matrix in the first chamber 13 will not flow out. Therefore, the storage bottle 1 is not prone to leakage when inverted, reducing the risk of leakage when the nebulizer is inverted.

[0044] In some embodiments, the bottle body 11 is provided with a partition 15, which is configured to divide the inner cavity of the bottle body 11 into a first chamber 13 and a second chamber 14. The partition 15 has a liquid inlet 16, and the switch valve 2 is located at the liquid inlet 16. The liquid inlet 16 is located at the end of the second chamber 14 away from the bottle opening 12.

[0045] In this embodiment, the partition 15 extends along the height direction, dividing the inner cavity of the bottle body 11 into a first chamber 13 and a second chamber 14 that extend along the height direction respectively. The switch valve 2 is located at the liquid inlet 16. The switch valve 2 opens or closes the liquid inlet 16 to make the first chamber 13 and the second chamber 14 connected or disconnected.

[0046] In some embodiments, the switching valve 2 includes a movable member 21 and an elastic member 22. The movable member 21 is configured to open the inlet port 16 under the action of an external force, and the elastic member 22 has elastic potential energy that causes the movable member 21 to block the inlet port 16. When the inlet port 16 is in the open state, the first chamber 13 and the second chamber 14 are connected through the inlet port 16. When the inlet port 16 is in the blocked state, the first chamber 13 and the second chamber 14 are not connected.

[0047] In this embodiment, the inlet 16 and the bottom 114 of the bottle are spaced apart in the height direction, thus providing space for the moving part 21 to move.

[0048] In use, the switching valve 2 of this embodiment moves the movable member 21 downward under the action of an external force, opening the inlet 16, and the first chamber 13 and the second chamber 14 are connected through the inlet 16. When no external force is applied, the movable member 21 is blocked by the elastic potential energy of the elastic member 22, thus disconnecting the first chamber 13 from the second chamber 14. The switching valve 2, including the movable member 21 and the elastic member 22, and the operating mode of the movable member 21 and the elastic member 22, gives the liquid storage bottle 1 the advantages of simple structure and stable operation.

[0049] In some embodiments, the movable part 21 is provided with a channel 213, the first opening 214 of the channel 213 is located on the end face of the movable part 21 facing the bottle mouth 12, and the second opening 215 of the channel 213 is located on the side wall of the movable part 21; when the liquid inlet 16 is in the open state, the first chamber 13, the second opening 215, the channel 213, the first opening 214 and the second chamber 14 are connected in sequence; when the liquid inlet 16 is in the blocked state, the first chamber 13 and the second opening 215 are not connected.

[0050] In this embodiment of the application, when the liquid inlet 16 is open, the aerosol generating matrix in the first chamber 13 can flow into the first opening 214 through the second opening 215 and the channel 213. When the liquid inlet 16 is blocked, the first chamber 13 and the second opening 215 are not connected, so the aerosol generating matrix in the first chamber 13 will not flow out, that is, there will be no leakage.

[0051] In the liquid storage bottle 1 of this application embodiment, when the liquid inlet 16 is in the open state, the aerosol generating matrix in the first chamber 13 enters the channel 213 through the second opening 215. By controlling the number of second openings 215 and the area of ​​a single second opening 215, the flow rate of the aerosol generating matrix can be controlled, thereby controlling the liquid supply flow rate of the liquid storage bottle 1 to meet the liquid supply requirements of the atomizer.

[0052] In some embodiments, multiple second openings 215 are provided, and the multiple second openings 215 are spaced apart around the outer periphery of the moving member 21. The above-described structure of the embodiments of this application allows the aerosol generating matrix to enter the channel 213 relatively uniformly through the multiple second openings 215.

[0053] Understandably, the number of second openings 215 is set according to usage requirements; for example, there may be two, three, or four second openings 215.

[0054] In other embodiments, a plurality of second openings 215 are provided, and the plurality of second openings 215 are spaced apart along the first direction Z.

[0055] In some embodiments, the switching valve 2 further includes a first seal 17 connected to the end of the movable member 21 opposite to the bottle opening 12. The first seal 17 is configured to seal the gap between the movable member 21 and the liquid inlet 16 when the liquid inlet 16 is in a blocked state. Thus, by providing the first seal 17, the liquid inlet 16 can be reliably sealed when it is blocked, preventing the aerosol generation matrix from leaking out through the gap between the movable member 21 and the liquid inlet 16, thus avoiding leakage.

[0056] In some embodiments, the movable member 21 is provided with a first contraction portion 216, which is arranged around the axis of the movable member 21 and located on the side of the second opening 215 opposite to the first opening 214. The first sealing member 17 is provided with a mounting hole and an annular groove 171, the mounting hole extending through the first sealing member 17 along the height direction, and the annular groove 171 surrounding the outer periphery of the mounting hole. The movable member 21 is inserted into the mounting hole, and a protrusion on the hole wall of the mounting hole is engaged within the first contraction portion 216, thus achieving the connection between the movable member 21 and the first sealing member 17.

[0057] The end of the separator 15 facing away from the bottle opening 12 contracts inward. When the inlet 16 is blocked, the end of the separator 15 facing away from the bottle opening 12 is inserted into the annular groove 171. In this way, the first sealing member 17 seals the gap between the moving member 21 and the inlet 16, and has the advantage of good sealing effect. When the moving member 21 moves downward under the action of external force, the first sealing member 17 moves downward with the moving member 21, and the annular groove 171 and the separator 15 move away from each other, so as to open the inlet 16.

[0058] In some embodiments, the elastic element 22 is a spring. A spring is a mechanical part that works by utilizing elasticity. A spring deforms under the action of an external force and returns to its original shape after the external force is removed. It is suitable for use in the liquid storage bottle 1 and has the advantage of long service life.

[0059] In some embodiments, the movable member 21 has an annular boss at its end facing the bottle opening 12, and the dividing portion 15 retracts inward at its end away from the bottle opening 12 to form a step. A spring is sleeved on the movable member 21, with one end of the spring abutting against the annular boss and the other end abutting against the step. The elastic member 22 has elastic potential energy that causes the movable member 21 to move away from the bottle opening 12 to block the liquid inlet 16. Without external force acting on the movable member 21, the spring keeps the movable member 21 constantly blocking the liquid inlet 16 to prevent the aerosol generation matrix in the first chamber 13 from flowing out through the liquid inlet 16.

[0060] In some embodiments, the bottle body 11 includes a first housing 111 and a first bottom cover 112. The first housing 111 has a bottle mouth 12, and one end of the first housing 111 opposite to the bottle mouth 12 is connected to the first bottom cover 112. The liquid storage bottle 1 also includes a second sealing member 18, which is connected to the first housing 111 and the first bottom cover 112 respectively to seal the gap between the first housing 111 and the first bottom cover 112 and prevent the bottle body 11 from leaking.

[0061] The first housing 111 contains a first chamber 13, a second chamber 14, and a partition 15. There is a gap between the liquid inlet 16 and the bottom of the bottle 114, which is used for the operation of the switch valve 2. The second sealing member 18 is wrapped around the gap between the liquid inlet 16 and the bottom of the bottle 114 to avoid affecting the operation of the switch valve 2.

[0062] In this embodiment of the liquid storage bottle 1, when not in use, the moving part 21 of the switch valve 2 is not subjected to external force. The elastic potential energy of the elastic member 22 causes the moving part 21 and the first sealing member 17 to block the liquid inlet 16, and the first chamber 13 and the second chamber 14 are not in communication. The aerosol generating matrix in the first chamber 13 will not flow into the second chamber 14, and the liquid storage bottle 1 will not leak.

[0063] When the storage bottle 1 is in use, the moving part 21 moves toward the side away from the bottle opening 12 under the action of external force. The second opening 215 enters the first chamber 13 along with the moving part 21. The first sealing part 17 moves away from the inlet 16 to open the inlet 16. The first chamber 13 is connected to the second chamber 14 through the inlet 16. The aerosol generating matrix in the first chamber 13 flows into the second chamber 14 through the inlet 16, and enters the second chamber 14 through the second opening 215, the channel 213, and the first opening 214 on the moving part 21.

[0064] When the switching valve 2 controls the connection between the first chamber 13 and the second chamber 14, since the inlet 16 is located at the end of the second chamber 14 away from the bottle opening 12, that is, the inlet 16 is close to the bottom 114 of the storage bottle 1, when the storage bottle 1 is upright, the aerosol generating matrix in the first chamber 13 will flow out and enter the second chamber 14, and the storage bottle 1 can provide the aerosol generating matrix for the storage chamber in the atomizer; when the storage bottle 1 is inverted, the height of the aerosol generating matrix is ​​lower than the inlet 16, so the aerosol generating matrix in the first chamber 13 will not flow out. Therefore, when the storage bottle 1 is inverted, leakage can be avoided.

[0065] In some embodiments, an atomizer is provided, which includes a liquid storage chamber 3, a liquid storage bottle 1 as described above, a bracket 41, and a liquid guiding element 42; the bracket 41 is fixedly connected to the liquid storage chamber 3, and a support portion 43 is provided on the side of the bracket 41 away from the liquid storage chamber 3. The support portion 43 is inserted into the second chamber 14 and abuts against the switching valve 2. The switching valve 2 connects the first chamber 13 and the second chamber 14; the liquid guiding element 42 is connected to the bracket 41, and one end of the liquid guiding element 42 is inserted into the second chamber 14, and the other end is inserted into the inner cavity of the liquid storage chamber 3.

[0066] In this embodiment of the atomizer, the support part 43 is inserted into the second chamber 14 and abuts against the switching valve 2, so that the moving part 21 of the switching valve 2 overcomes the elastic potential energy of the elastic member 22 and moves the first sealing member 17 toward the bottom of the bottle 114 to open the liquid inlet 16, so that the first chamber 13 and the second chamber 14 are connected, and the aerosol generating matrix in the first chamber 13 can flow into the second chamber 14. One end of the liquid guiding element 42 is inserted into the second chamber 14, and the other end is inserted into the inner cavity of the liquid storage tank 3, so as to guide the aerosol generating matrix flowing into the second chamber 14 into the inner cavity of the liquid storage tank 3.

[0067] Because the inlet 16 of the storage bottle 1 is close to the bottom 114 of the storage bottle 1, when the storage bottle 1 is upright, the aerosol generating matrix in the first chamber 13 will flow out and enter the second chamber 14. The liquid guiding element 42 guides the aerosol generating matrix in the second chamber 14 into the inner cavity of the storage chamber 3. When the storage bottle 1 is inverted, the height of the aerosol generating matrix is ​​lower than the inlet 16, so that the aerosol generating matrix in the first chamber 13 will not flow out into the second chamber 14, which can avoid the leakage problem of the storage bottle 1 when it is inverted; and the liquid guiding element 42 will not continuously introduce the aerosol generating matrix into the inner cavity of the storage chamber 3, avoiding the leakage problem of the atomizer caused by excessive aerosol generating matrix entering the storage chamber 3.

[0068] In some embodiments, the bracket 41 includes a first through hole 44 and a second through hole 47. One end of the first through hole 44 is located on the end face of the support portion 43 and is connected to the first opening 214 of the channel 213 in the switch valve 2. One end of the second through hole 47 is connected to the first through hole 44 and the other end is connected to the inner cavity of the liquid storage tank 3. Along the radial direction of the second through hole 47, the diameter of the second through hole 47 is smaller than the diameter of the first through hole 44, and the liquid guiding element 42 passes through the first through hole 44 and the second through hole 47.

[0069] In this embodiment, the diameter of the second through hole 47 is smaller than the diameter of the first through hole 44. When the liquid guiding element 42 is disposed through the first through hole 44 and the second through hole 47, there is a gap between the side wall of the liquid guiding element 42 and the hole wall of the first through hole 44. When the atomizer is inverted, part of the aerosol generating matrix located in the second chamber can flow into the gap between the liquid guiding element 42 and the first through hole 44, thus preventing leakage of the aerosol generating matrix when the atomizer is inverted. The contact between the liquid guiding element 42 and the hole wall of the second through hole 47 fixes the liquid guiding element 42 and prevents it from moving.

[0070] Since the first through hole 44 faces and communicates with the first opening 214, the liquid guiding element 42 can be inserted into the channel 213 through the first opening 214 to make more contact with the aerosol generating matrix and more smoothly introduce the aerosol generating matrix in the storage bottle 1 into the inner cavity of the storage chamber 3.

[0071] In some embodiments, the support 41 further includes a plurality of ventilation holes 45, which are arranged around the outer periphery of the second through hole 47. One end of the ventilation hole 45 communicates with the first through hole 44, and the other end of the ventilation hole 45 communicates with the inner cavity of the liquid storage tank 3. In this embodiment, the ventilation holes 45 are used for gas circulation within the inner cavity of the liquid storage tank 3 and the second chamber 14 to ensure pressure balance, so that the aerosol generation matrix can flow into the inner cavity of the liquid storage tank 3.

[0072] In some embodiments, the atomizer further includes a third seal 51 disposed between the side wall of the support 43 and the cavity wall of the second chamber 14 to prevent leakage of the aerosol generating matrix between the support 43 and the cavity wall of the second chamber 14.

[0073] In some embodiments, to facilitate the installation of the third seal 51, a second contraction portion 46 is also provided on the support portion 43. The second contraction portion 46 is arranged around the axis of the support portion 43, and the third seal 51 is locked inside the second contraction portion 46.

[0074] In some embodiments, the atomizer further includes, in the height direction, a mouthpiece 52, absorbent cotton 53, a third housing 54, a liquid storage tank 3, a heating element 57, an electrical connector 58, a third bottom cover 59, a bracket 41, and a mounting plate 61. Along the height direction, one end of the third housing 54 is connected to the mouthpiece 52, and the other end of the third housing 54 is connected to the third bottom cover 59. The absorbent cotton 53, the liquid storage tank 3, the heating element 57, the bracket 41, and the liquid storage bottle 1 are all disposed within the space formed by the third housing 54 and the third bottom cover 59.

[0075] Oil-absorbing cotton 53 is disposed at the end of the suction nozzle 52 near the liquid storage tank 3. The liquid storage tank 3 includes a second housing 32, the end of the second housing 32 near the suction nozzle 52 is connected to the fifth seal 60, and the end of the second housing 32 away from the suction nozzle 52 is connected to the fourth seal 56. The second housing 32, the fifth seal 60, and the fourth seal 56 surround and form the inner cavity of the liquid storage tank 3. An oil storage element 55 is provided inside the inner cavity of the liquid storage tank 3.

[0076] A heating element 57 is disposed inside the liquid storage chamber 3. The heating element 57 is used to heat the aerosol generating matrix inside the oil storage element 55 to generate aerosol, which flows out through the suction nozzle 52. A mounting plate 61 is disposed on the side wall of the third housing 54. An electrical connector 58 is disposed on the mounting plate 61. The electrical connector 58 is used to electrically connect the heating element 57 to an external power supply, so that the heating element 57 can generate heat to heat the aerosol generating matrix.

[0077] When the atomizer of this embodiment is in use, since the support part 43 is inserted into the second chamber 14 and abuts against the switch valve 2, the liquid inlet 16 is always in the open state, so that the first chamber 13 and the second chamber 14 are connected.

[0078] With the atomizer upright, the aerosol generating matrix in the first chamber 13 flows into the second chamber 14 through the inlet 16, and also enters the second chamber 14 through the second opening 215, channel 213, and first opening 214 on the moving part 21. The liquid guiding element 42 is inserted into the end of the channel 213 near the bottom 114 of the bottle, and guides the aerosol generating matrix flowing into the channel 213 into the inner cavity of the storage tank 3. When the inlet 16 is open, the second opening 215 is located on the side of the inlet 16 opposite to the bottle opening 12.

[0079] When the storage bottle 1 is inverted, the height of the aerosol generating matrix is ​​lower than the liquid inlet 16, so that the aerosol generating matrix in the first chamber 13 will not flow out to the second chamber 14. The liquid guiding element 42 cannot continuously contact the aerosol generating matrix to introduce it into the inner cavity of the storage chamber 3, which can avoid the problem of atomizer oil leakage caused by excessive aerosol generating matrix entering the storage chamber 3.

[0080] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
