Description

Atomizer and aerosol generator

[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese patent applications filed on January 20, 2025, with application number 202520131792.X, entitled "Atomizer and Aerosol Generating Apparatus" and filed on April 25, 2025, with application number 202510534161.7, entitled "Atomizer and Aerosol Generating Apparatus", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of aerosol generation technology, and particularly to atomizers and aerosol generation devices. Background Technology

[0004] In aerosol generators, the atomizer is typically configured with the liquid channel closed before installation into the battery pack, and then opened after installation. As one existing implementation example, before installation, a silicone rod is inserted through the mouthpiece to block the liquid inlet between the reservoir and the atomizer assembly. After installation, the silicone rod is removed, opening the inlet. However, this wick-and-liquid separation method, with the silicone rod protruding from the mouthpiece, means the liquid channel cannot be closed once opened. This means liquid leakage is still possible during subsequent use after installation, and the extended silicone rod compromises product integrity.

[0005] Application content

[0006] This addresses the issue of potential liquid matrix leakage during subsequent use after the atomizer is installed in the battery assembly.

[0007] One embodiment of this application provides an atomizer, comprising:

[0008] A housing, within which a reservoir is defined for storing a liquid matrix;

[0009] The suction nozzle is located at one end of the housing;

[0010] The first seal is disposed adjacent to the other end of the housing;

[0011] The atomizing component, housed within the housing, is used to atomize the liquid matrix to generate an aerosol;

[0012] A first support member is disposed inside the housing and surrounds the atomizing assembly. The first support member is provided with an inlet hole for guiding the liquid matrix in the liquid storage chamber to the atomizing assembly.

[0013] The nozzle is operably rotatable relative to the housing between a first position and a second position. The first support is connected to the nozzle and can be driven by the nozzle to move linearly along the axis of the atomizer. When the nozzle is in the first position, the nozzle drives the first support to move to a position where the liquid inlet avoids the first seal. When the nozzle is in the second position, the nozzle drives the first support to move to a position where the liquid inlet is blocked by the first seal, thereby preventing the liquid matrix from entering the atomizing assembly from the reservoir.

[0014] One embodiment of this application provides an atomizer, wherein the nozzle is provided with a first protrusion, and a first support member is provided with a limiting groove, the limiting groove providing a sliding path for the first protrusion within the limiting groove.

[0015] One embodiment of this application provides an atomizer in which the limiting groove is configured as an inclined groove or an arc-shaped groove that deviates from the axial direction of a first support member.

[0016] One embodiment of this application provides an atomizer in which a first support member is restricted from rotating relative to a housing.

[0017] One embodiment of this application provides an atomizer, the housing including a third protrusion that radially protrudes from the inner surface of the housing, and a first support member including a longitudinally extending guide groove, the third protrusion being received in the guide groove, the guide groove being used to limit the first support member to linear movement in the axial direction of the atomizer.

[0018] One embodiment of this application provides an atomizer, wherein the mouthpiece is provided with a second protrusion, and the housing is provided with a groove for receiving the second protrusion. The mouthpiece and the housing are slidably connected by the second protrusion and the groove to achieve relative rotation.

[0019] One embodiment of this application provides an atomizer in which a groove extends circumferentially along the housing.

[0020] One embodiment of this application provides an atomizer, the housing including an end surrounding at least a portion of the mouthpiece, the end being provided with a first mark for indicating that the mouthpiece is rotated to a first position, and a second mark for indicating that the mouthpiece is rotated to a second position.

[0021] One embodiment of this application provides an atomizer, wherein a first seal is provided with a raised rib on the side facing the first support member, and when the nozzle is in the second position, the first support member moves longitudinally such that the liquid inlet is located on the side of the raised rib away from the liquid storage cavity.

[0022] One embodiment of this application provides an atomizer, the atomizing component including a second support member and a liquid guiding member and a heating element located within the second support member, and a liquid storage member for retaining a portion of the liquid matrix is ​​disposed between the second support member and the first support member.

[0023] One embodiment of this application provides an aerosol generating device, including a battery assembly and the aforementioned atomizer, wherein the battery assembly provides electrical energy to the atomizer.

[0024] The nozzle of this atomizer can be operably rotated relative to the housing between a first position and a second position. This allows the user to close the liquid inlet when the atomizer is in storage, during transport, or when it is not in use, and to reversibly open the liquid inlet when the user uses the atomizer. This prevents liquid leakage and avoids air entering the reservoir, which could degrade the liquid matrix. Furthermore, by rotating the nozzle to drive the linear movement of the first support member and restricting its rotation, the user can avoid the first support member causing the atomizing assembly to rotate, which could lead to distortion of the heating element and affect the atomization effect, or the risk of electrical connection failure due to twisting of the conductive pins.

[0074] Example 1

[0075] One embodiment of this application provides an atomizer 10, including a housing 1, a nozzle 2, a first seal 3, an atomizing assembly 4, and a first support 5. The housing 1 defines a liquid storage chamber 11 for storing a liquid matrix; the nozzle 2 is disposed at one end of the housing 1. The first seal 3 is disposed adjacent to the other end of the housing 1. The atomizing assembly 4 is disposed within the housing 1 and is used to atomize the liquid matrix to generate an aerosol. The first support 5 is disposed within the housing 1 and surrounds the atomizing assembly 4, and the first support 5 has a liquid inlet 51 for guiding the liquid matrix in the liquid storage chamber 11 to the atomizing assembly 4. The nozzle 2 is operably rotatable relative to the housing 1 between a first position and a second position. The first support member 5 is connected to the nozzle 2 and can be driven by the nozzle 2 to move linearly along the axial direction of the atomizer 10. When the nozzle 2 is in the first position, the nozzle 2 drives the first support member 5 to move to a position where the liquid inlet 51 avoids the first seal 3. When the nozzle 2 is in the second position, the nozzle 2 drives the first support member 5 to move to a position where the liquid inlet 51 is blocked by the first seal 3, so that the liquid matrix is ​​prevented from entering the atomizing assembly 4 from the liquid storage chamber 11.

[0076] The mouthpiece 2 of the atomizer 10 of this application can be operably rotated relative to the housing 1 between a first position and a second position. This allows the user to close the liquid inlet 51 when the atomizer 10 is in storage, in transit, or when it is not in use. When the user uses the atomizer 10, the liquid inlet 51 can be reversibly opened to prevent liquid leakage and to prevent air from entering the liquid reservoir 11 and causing the liquid matrix to deteriorate. On the other hand, by rotating the mouthpiece 2 to drive the first support member 5 to move linearly and restricting its rotation, it is possible to prevent the first support member 5 from rotating along with the atomizing assembly 4, which would cause the heating element 43 to twist and affect the atomization effect, or to avoid the risk of the conductive pin 44 twisting and causing electrical connection failure.

[0077] In one embodiment of this application, the liquid matrix may comprise a liquid containing tobacco-containing substances with volatile tobacco aroma components, or it may be a liquid containing non-tobacco substances. The liquid matrix may comprise water, pharmaceutical solutions, solvents, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures, etc. Fragrances may include areca nut extract, menthol, peppermint, spearmint oil, various fruit flavoring components, etc., but are not limited thereto. Flavorings contain ingredients that can provide the user with various fragrances or flavors. Vitamin mixtures may be mixtures containing at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but are not limited thereto. Based on the different properties of the liquid matrix, aerosol matrix reservoirs can be used in different fields, such as medical applications and electronic aerosol atomization.

[0078] In one embodiment of this application, the suction nozzle 2 and the first support member 5 are configured to convert circumferential motion into axial motion. In another embodiment of this application, the suction nozzle 2 may be provided with a first external thread, and the first support member 5 may be provided with a second external thread. The first and second external threads are adapted to each other, allowing the suction nozzle 2 to rotate circumferentially under the user's operation, and the first support member 5 to generate axial motion under the action of the suction nozzle.

[0079] In one embodiment of this application, the suction nozzle 2 is provided with a first sliding portion 21, and the first support member 5 is provided with a second sliding portion 52. The suction nozzle 2 and the first support member 5 are slidably connected through the first sliding portion 21 and the second sliding portion 52.

[0080] In one embodiment of this application, the suction nozzle 2 is provided with a first protrusion 211, and the first support member 5 is provided with a limiting groove 521, which provides a sliding path for the first protrusion 211 within the limiting groove 521. In another embodiment of this application, the limiting groove 521 is configured as an inclined groove or an arc-shaped groove that deviates from the axial direction of the first support member 5.

[0081] In one embodiment of this application, the first sliding portion 21 is a limiting groove, the second sliding portion 52 is a first protrusion, and the limiting groove defines the path of the suction nozzle 2 from the first position to the second position. In another embodiment of this application, the limiting groove is configured as an inclined groove or an arc-shaped groove that deviates from the axial direction of the first support member 5.

[0082] In one embodiment of this application, the mouthpiece 2 includes a mouth part 22, an air tube 23, and a main body part 24. The mouth part 22 is for the user to hold in their mouth. The air tube 23 is connected to one end of the mouth part 22 and is used to deliver aerosol to the user. The main body part 24 is connected to the mouth part 22 and is covered by the air tube, and is used to connect the mouthpiece 2 and the housing 1.

[0083] In one embodiment of this application, the first sealing member 3 includes a first through hole 31 and a first groove 32. One end of the first support member 5 is inserted into the air tube 23, and the other end of the first support member 5 is inserted into the first groove 32 and communicates with the first support member 5 and the first through hole 31, so that air enters the first support member 5 from the first through hole 31, carries away the aerosol generated by the heating of the atomizing component 4, and is delivered to the user through the air tube 23.

[0084] In one embodiment of this application, the suction nozzle 2 is provided with a third sliding part 25, and the housing 1 is provided with a fourth sliding part 12. The suction nozzle 2 and the housing 1 are slidably connected through the third sliding part 25 and the fourth sliding part 12, thereby allowing the suction nozzle 2 to rotate relative to the housing 1.

[0085] In one embodiment of this application, the suction nozzle 2 is provided with a second protrusion 251, and the housing 1 is provided with a groove 121 for receiving the second protrusion 251. The suction nozzle 2 and the housing 1 achieve relative rotation through the sliding connection of the second protrusion 251 and the groove 121.

[0086] In one embodiment of this application, the groove 121 extends along the circumferential direction of the housing 1.

[0087] In one embodiment of this application, the housing 1 includes an end 14 surrounding at least a portion of the suction nozzle 2. The end 14 is provided with a first mark 141 for indicating that the suction nozzle 2 has been rotated to a first position, and a second mark 142 for indicating that the suction nozzle 2 has been rotated to a second position. In one embodiment of this application, the first mark 141 is an unlock mark or an "ON" mark. In one embodiment of this application, the second mark 142 is a lock mark or an "OFF" mark.

[0088] In one embodiment of this application, the first sealing member 3 is provided with a rib 33 on the side facing the first support member 5. When the suction nozzle 2 is in the second position, the first support member 5 moves longitudinally so that the liquid inlet 51 is located on the side of the rib 33 away from the liquid storage cavity 11.

[0089] In one embodiment of this application, the atomizing component 4 includes a second support member 41 and a liquid guiding member 42 and a heating element 43 located within the second support member 41. A liquid storage member 6 is disposed between the second support member 41 and the first support member 5 to retain a portion of the liquid matrix. The liquid storage member 6 can prevent the liquid matrix in the liquid storage chamber 11 from leaking from the atomizing component 4. In addition, the liquid storage member 6 retains a portion of the liquid matrix around the atomizing component 4, so that even when the liquid supply in the liquid storage chamber is insufficient, a sufficient amount of liquid matrix can still be supplied to the atomizing component 4. This is beneficial in preventing the atomizing component 4 from overheating locally due to insufficient liquid supply, which could lead to the generation of substances such as formaldehyde.

[0090] In one embodiment of this application, the liquid reservoir 6 can be made of an elastic organic porous material. The liquid reservoir 6 can have a hardness or flexibility between that of conventional flexible plant cotton / non-woven fabric (Shore hardness less than 20A) and rigid porous ceramic / microporous metal (Shore hardness greater than 80A), thus exhibiting structural stability with extremely low expansion after absorbing and wetting the liquid matrix, while also possessing a certain degree of hardness for easy fixation and retention. In one embodiment of this application, the liquid reservoir 6 can be made of rigid synthetic cotton.

[0091] In one embodiment of this application, the atomizing component 4 includes a second support 41, a liquid guiding component 42, a heating element 43, conductive pins 44, and a fixing component 45. The second support 41 is disposed within the liquid storage component 6, and has a passage through which the liquid matrix can pass. The liquid guiding component 42 has a liquid guiding surface and a heating surface disposed opposite to each other. The liquid guiding surface is in fluid communication with the liquid storage component 6. The liquid guiding component 42 guides the liquid matrix from the liquid guiding surface to the heating surface. One side of the heating surface is an atomization chamber. Under the heating of the heating element 43 on the heating surface, the liquid matrix is ​​atomized to generate an aerosol that enters the atomization chamber. In one embodiment of this application, the liquid guiding component 42 includes a porous body, which can be a fiber, such as cotton fiber, polypropylene fiber, polyester fiber, or nylon fiber. The porous body can be porous ceramic or porous metal. This application does not limit the structure and composition of the porous body. In one embodiment of this application, the second support 41 is a steel pipe. The conductive pins 44 are connected to the heating element 43 and are used to electrically connect to the electrode post 7. The fixing member 45 is disposed inside the first support member 41 to fix the conductive pin 44 and prevent the conductive pin 44 from rotating in the circumferential direction.

[0092] In one embodiment of this application, the atomizing component 4 may include an ultrasonic element capable of high-frequency vibration under ultrasonic drive. The atomizing component 4 utilizes ultrasonic vibration to atomize the liquid matrix into an aerosol. Of course, the atomizing component 4 may also include other elements capable of atomizing the liquid matrix into an aerosol.

[0093] In one embodiment of this application, the liquid guiding element 42 can be made of an elastic organic porous material. The liquid guiding element 42 can have a hardness or flexibility between that of conventional flexible plant cotton / non-woven fabric (Shore hardness less than 20A) and rigid porous ceramic / microporous metal (Shore hardness greater than 80A), thus exhibiting structural stability with extremely low expansion after absorbing and wetting the liquid matrix, while also possessing a certain degree of hardness for easy fixation and retention. In one embodiment of this application, the liquid guiding element 42 can be made of rigid synthetic cotton.

[0094] In one embodiment of this application, a fixing part 34 is provided on the inner surface of the first through hole 31 of the first sealing member 3, and a conductive pin 45 extends out of the first through hole 31 and is fixed to the fixing part 34. In one embodiment of this application, the atomizer 10 further includes an electrode post 7, which is disposed in the second groove 25 of the first sealing member 3 and connected to the conductive pin 44 of the atomizing component 4. The electrode post 7 is used for electrical connection with the battery component 20.

[0095] In one embodiment of this application, a second seal 8 is provided at one end of the housing 1 away from the first seal 3. The housing 1, the first seal 3 and the second seal 8 together define a liquid storage chamber 11 for storing a liquid matrix. The second seal 8 can prevent the liquid preparation from leaking between the housing 1 and the nozzle 2.

[0096] In one embodiment of this application, the first support member 5 is restricted from rotating relative to the housing 1.

[0097] In one embodiment of this application, the housing 1 includes a third protrusion 13 that radially protrudes from the inner surface of the housing 1. The first support member 5 includes a longitudinally extending guide groove 53, and the third protrusion 13 is disposed within the guide groove 53. The third protrusion 13 restricts the first support member 5 to move linearly in the axial direction of the atomizer 10, thereby restricting the rotation of the first support member 5 relative to the housing 1 during the rotation of the nozzle 2. This is advantageous for preventing the first support member 5 from simultaneously driving the heating element 43 and the conductive pin 44 in the atomizing assembly 4 to rotate and causing torsion.

[0098] Example 2

[0099] One embodiment of this application provides an atomizer, as shown in Figures 11-22, which includes a housing 1, a mouthpiece 2, a first sealing member 3, an atomizing assembly 4, a first support member 5, and a bracket 6.

[0100] The housing 1 has a liquid storage chamber 11 defined inside for storing the liquid matrix.

[0101] The suction nozzle 2 is disposed at one end of the housing 1 and can be operably rotated relative to the housing 1 between a first position and a second position. The suction nozzle 2 can be held in the mouth by a user.

[0102] The atomizing component 4 is disposed inside the housing 1 and is used to atomize the liquid matrix to generate an aerosol.

[0103] The first support member 5 is configured as a tube and surrounds or houses the atomizing assembly 4. The first support member 5 has a proximal end near the nozzle 2 and a relatively distal end. The first support member 5 is provided with an inlet hole 51 for guiding the liquid matrix in the liquid storage chamber to the atomizing assembly 4.

[0104] The first seal 3 is disposed adjacent to the distal end of the first support 5 and is used to seal the liquid inlet hole 51.

[0105] The bracket 6 is fixedly connected to the proximal end of the first support member 5. The housing 1 is provided with a guide part 12 near the proximal end. The guide part 12 cooperates with the bracket 6 and is used to guide the bracket 6 to move longitudinally along the atomizer 10. The mouthpiece 2 is movably connected to the bracket 6, thereby driving the bracket 6 and the first support member 5 to move longitudinally along the atomizer 10 during rotation.

[0106] When the nozzle 2 is in the first position, the first support member 5 moves under the drive of the nozzle 2 to the position where the liquid inlet 51 avoids the position of the first seal member 3; when the nozzle 2 is in the second position, the first support member 5 moves under the drive of the nozzle 2 to the position where the liquid inlet 51 is blocked by the first seal member 3, so that the liquid matrix is ​​prevented from entering the atomizing component 4 from the liquid storage chamber 11.

[0107] The nozzle 2 of the atomizer 10 of this application can be operatively rotated relative to the housing 1 between a first position and a second position, so that when the atomizer 10 is in storage, in transport or when it is not in use, the user can close the liquid inlet 51, and when the user uses the atomizer 10, the liquid inlet 51 can be reversibly opened to prevent liquid leakage and to prevent air from entering the liquid storage chamber 11 and causing the liquid matrix to deteriorate.

[0108] In one embodiment of this application, the liquid matrix may comprise a liquid containing tobacco-containing substances with volatile tobacco aroma components, or it may be a liquid containing non-tobacco substances. The liquid matrix may comprise water, pharmaceutical solutions, solvents, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures, etc. Fragrances may include areca nut extract, menthol, peppermint, spearmint oil, various fruit flavoring components, etc., but are not limited thereto. Flavorings contain ingredients that can provide the user with various fragrances or flavors. Vitamin mixtures may be mixtures containing at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but are not limited thereto. Based on the different properties of the liquid matrix, aerosol matrix reservoirs can be used in different fields, such as medical applications and electronic aerosol atomization.

[0109] In one embodiment of this application, the guide portion 12 includes a guide ramp 121 extending in a direction offset from the axis of the atomizer 10. In another embodiment of this application, the guide ramp 121 is configured to extend in a spiral manner. In another embodiment of this application, when the mouthpiece 2 rotates relative to the housing 1, the support 6 moves relative to the guide ramp 121 both along the axis of the atomizer 10 and in the circumferential direction of the atomizer 10.

[0110] In one embodiment of this application, the suction nozzle 2 moves circumferentially relative to the housing 1, and the support 6 moves in a spiral shape along the guide slope 121 of the housing 1 under the drive of the suction nozzle 2, thereby driving the first support member 5 to move in a spiral shape, so that the first support member 5 moves relative to the first sealing member 3, thereby opening or closing the liquid inlet 51.

[0111] In one embodiment of this application, the first support member 5 is a steel pipe. In another embodiment of this application, the thickness of the first support member 5 is 0.15mm-0.50mm. The first support member 5 of this application is connected to the nozzle 2 via the bracket 6, and the guide part 12 cooperates with the bracket 6 to drive the first support member 5. Compared with the scheme of opening a spiral groove on the first support member 5 to directly cooperate with the nozzle 2, the first support member 5 of this application will not be twisted or deformed during relative rotation with the nozzle 2, causing the transmission connection between the first support member 5 and the nozzle 2 to fail. The first support member 5 of this application is not easily deformed during the rotation of the nozzle 2, and the connection between the first support member 5 and the nozzle 2 is more stable, making the structure of the atomizer 10 more stable.

[0120] In one embodiment of this application, as shown in FIG18, the first sealing member 3 includes a first through hole 32 and a second groove 33. One end of the first support member 5 is inserted into the air tube 25, and the other end of the first support member 5 is inserted into the second groove 33 and communicates with the first support member 5 and the first through hole 32, so that air enters the first support member 5 from the first through hole 32, carries away the aerosol generated by the heating of the atomizing component 4, and is delivered to the user through the air tube 25.

[0121] In one embodiment of this application, as shown in FIG11, the atomizer 10 includes a third seal 8, which is disposed in the housing 1 at one end away from the first seal 3. The first seal 3, the housing 1 and the third seal 8 together form a liquid storage chamber 11.

[0122] In one embodiment of this application, as shown in FIG16, the housing 1 includes a mounting portion 13, which extends inward from one end of the housing 1, and a third seal 8 is disposed within the mounting portion 13.

[0123] In one embodiment of this application, the housing 1 includes a positioning post 14 extending from the inner surface of the housing 1 into the housing 1.

[0128] In one embodiment of this application, as shown in FIG18, the first sealing member 3 is provided with a first rib 31 on the side facing the first support member 5. When the nozzle 2 is in the second position, the first support member 5 moves so that the liquid inlet 51 is located on the side of the first rib 31 away from the liquid storage chamber 11, so that the liquid matrix is ​​prevented from entering the atomizing component 4 from the liquid storage chamber 11.

[0129] In one embodiment of this application, as shown in FIG20, the atomizing component 4 includes a second support member 41 and a liquid guiding member 42 and a heating element 43 located within the second support member 41. A liquid storage member 9 for retaining a portion of the liquid matrix is ​​disposed between the second support member 41 and the first support member 5. The liquid storage member 9 can prevent the liquid matrix in the liquid storage chamber 11 from leaking from the atomizing component 4. In addition, the liquid storage member 9 retains a portion of the liquid matrix around the atomizing component 4, so that even when the liquid supply in the liquid storage chamber is insufficient, a sufficient amount of liquid matrix can still be supplied to the atomizing component 4. This is beneficial in preventing the atomizing component 4 from overheating locally due to insufficient liquid supply and generating substances such as formaldehyde.

[0130] In one embodiment of this application, the liquid reservoir 9 can be made of an elastic organic porous material. The liquid reservoir 9 can have a hardness or flexibility between that of conventional flexible plant cotton / non-woven fabric (Shore hardness less than 20A) and rigid porous ceramic / microporous metal (Shore hardness greater than 80A), thus exhibiting structural stability with extremely low expansion after absorbing and wetting the liquid matrix, while also possessing a certain degree of hardness for easy fixation and retention. In one embodiment of this application, the liquid reservoir 9 can be made of rigid synthetic cotton.

[0131] In one embodiment of this application, as shown in FIG21, the atomizing component 4 includes a second support 41, a liquid guiding component 42, a heating element 43, conductive pins 44, and a fixing component 45.

The liquid guiding component 42 has a liquid guiding surface and a heating surface disposed opposite to each other. The liquid guiding surface is in fluid communication with the liquid storage component 9. The liquid guiding component 42 guides the liquid matrix from the liquid guiding surface to the heating surface. One side of the heating surface is an atomization chamber.

The fixing member 45 is disposed inside the first support member 41 for fixing the conductive pin 44 and preventing the conductive pin 44 from rotating in the circumferential direction.

[0132] In one embodiment of this application, a fixing part 34 is provided on the inner surface of the first through hole 31 of the first sealing member 3, and a conductive pin 45 extends out of the first through hole 32 and is fixed to the fixing part 34. In one embodiment of this application, the atomizer 10 further includes an electrode post 46, which is disposed in the second groove 35 of the first sealing member 3 and connected to the conductive pin 45 of the atomizing component 4. The electrode post 36 is used for electrical connection with the battery component 20.

[0133] In one embodiment of this application, one end of the atomizing component 4 abuts against the mouthpiece 2, and the other end of the atomizing component 4 is fitted inside the first through hole 32 of the first sealing member 3 to prevent the atomizing component 4 from moving along the circumferential direction of the first support member 5, and to prevent the conductive pin 45 from rotating in the circumferential direction. In one embodiment of this application, the conductive pin 45 may be reserved with sufficient length to prevent the conductive pin 45 from causing the heating element 43 to rotate in the circumferential direction.

[0134] In one embodiment of this application, the atomizing component 4 may include an ultrasonic element capable of high-frequency vibration under ultrasonic drive. The atomizing component 4 utilizes ultrasonic vibration to atomize the liquid matrix into an aerosol. Of course, the atomizing component 4 may also include other elements capable of atomizing the liquid matrix into an aerosol.

[0135] In one embodiment of this application, the liquid guiding element 42 can be made of an elastic organic porous material. The liquid guiding element 42 can have a hardness or flexibility between that of conventional flexible plant cotton / non-woven fabric (Shore hardness less than 20A) and rigid porous ceramic / microporous metal (Shore hardness greater than 80A), thus exhibiting structural stability with extremely low expansion after absorbing and wetting the liquid matrix, while also possessing a certain degree of hardness for easy fixation and retention. In one embodiment of this application, the liquid guiding element 42 can be made of rigid synthetic cotton.
