Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and particularly to atomizers and aerosol generation devices. Background Technology

[0002] A typical aerosol generating device typically has a closed liquid channel between the reservoir and the atomizing component in the atomizer when in storage or unused. However, this channel can be opened by the user during use. As an example of existing technology, before the atomizer is installed with the battery, a silicone rod is inserted through the mouthpiece to block the liquid inlet between the reservoir and the atomizing component. When the atomizer is in use, the user removes the silicone rod, opening the inlet. However, this method of separating the coil with the silicone rod is irreversible; once the liquid channel is opened, it cannot be closed again. This means that liquid matrix leakage may still occur during subsequent use, and the presence of the silicone rod protruding from the mouthpiece compromises product integrity. Utility Model Content

[0003] To address the issue that liquid matrix leakage may still occur during subsequent use of atomizers with liquid channel blocking mechanisms.

[0004] This application provides an embodiment of an atomizer, including:

[0005] A housing, wherein a reservoir for storing a liquid matrix is ​​defined within the housing;

[0006] A suction nozzle is disposed at one end of the housing and is operable to rotate relative to the housing between a first position and a second position;

[0007] An atomizing component, disposed within the housing, is used to atomize a liquid matrix to generate an aerosol;

[0008] A first support member is configured as a tube and surrounds or houses the atomizing assembly. The first support member has a proximal end near the mouthpiece and a opposite distal end. The first support member is provided with a liquid inlet for guiding the liquid matrix in the liquid storage chamber to the atomizing assembly.

[0009] A first sealing element is disposed adjacent to the distal end of the first support element and is used to seal the liquid inlet hole;

[0010] The bracket is fixedly connected to the proximal end of the first support member. The housing is provided with a guide part near the proximal end. The guide part cooperates with the bracket and is used to guide the bracket to move longitudinally along the atomizer. The mouthpiece is movably connected to the bracket, thereby driving the bracket and the first support member to move longitudinally along the atomizer during rotation.

[0011] When the nozzle is in the first position, the first support moves under the drive of the nozzle to a position where the liquid inlet avoids the first seal; when the nozzle is in the second position, the first support moves under the drive of the nozzle to a position where the liquid inlet is blocked by the first seal, so that the liquid matrix is ​​prevented from entering the atomizing component from the liquid storage chamber.

[0012] In some embodiments, the guide includes a guide ramp that extends in a direction offset from the axis of the atomizer, or the guide ramp is configured to extend in a spiral manner.

[0013] In some embodiments, the support is configured to be non-rotatable relative to the mouthpiece, but slidable relative to the mouthpiece along the longitudinal direction of the atomizer.

[0014] In some embodiments, the mouthpiece includes a snap-fit ​​groove extending longitudinally along the atomizer, and at least a portion of the bracket is slidably disposed within the snap-fit ​​groove.

[0015] In some embodiments, the support includes a first main body and a second main body, the first main body being connected to the first support member and the second main body being connected to the suction nozzle.

[0016] In some embodiments, the first main body is fitted over the first support member.

[0017] In some embodiments, the first main body is annular, and the inner diameter of the end of the first main body away from the first support is smaller than the inner diameter of the end of the first main body near the first support.

[0018] In some embodiments, a reinforcing portion is provided between the first main body portion and the second main body portion.

[0019] In some embodiments, a second seal is provided between the nozzle and the housing.

[0020] In some embodiments, the atomizer includes a third seal disposed within the housing at one end away from the first seal.

[0021] In some embodiments, the housing includes a mounting portion extending inward from one end of the housing, and the third seal is disposed within the mounting portion.

[0022] In some embodiments, the suction nozzle is provided with a first protrusion, and the housing is provided with a groove for receiving the first protrusion. The suction nozzle and the housing can rotate relative to each other through a sliding connection between the first protrusion and the groove.

[0023] In some embodiments, the outer surface of the housing is provided with a first mark, and the outer surface of the suction nozzle is provided with a second mark. When the suction nozzle is in the first position, the first mark and the second mark are positioned opposite each other.

[0024] In some embodiments, the first seal is provided with a first rib on the side facing the first support member. When the nozzle is in the second position, the first support member moves such that the liquid inlet is located on the side of the first rib away from the liquid storage cavity.

[0025] This application provides an embodiment of an aerosol generating device, including a battery assembly and the aforementioned atomizer, wherein the battery assembly provides electrical energy to the atomizer.

[0026] The nozzle of the atomizer of this application can be operably rotated relative to the housing between a first position and a second position, so that when the atomizer is in storage, in transportation or when it is not in use, the user can close the liquid inlet, and when the user uses the atomizer, the liquid inlet can be reversibly opened to prevent liquid leakage and prevent air from entering the liquid reservoir and causing the liquid matrix to deteriorate.

[0055] One embodiment of this application provides an atomizer, such as Figure 1-2 As shown, the atomizer includes a housing 1, a mouthpiece 2, a first seal 3, an atomizing assembly 4, a first support 5, and a bracket 6.

[0056] The housing 1 has a liquid storage chamber 11 defined inside for storing the liquid matrix.

[0057] 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.

[0058] The atomizing component 4 is disposed inside the housing 1 and is used to atomize the liquid matrix to generate an aerosol.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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 menthol, peppermint, spearmint oil, various fruit flavoring components, etc., but are not limited to these. 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 to these. Based on the different properties of the liquid matrix, aerosol matrix reservoirs can be used in different fields, such as medical and electronic aerosol atomization.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] In one embodiment of this application, the bracket 6 has a first thread, and the first support member 5 has a second thread; the bracket 6 and the first support member 5 are connected by the first thread and the second thread. In another embodiment of this application, the bracket 6 has a first snap-fit ​​portion, and the first support member 5 has a second snap-fit ​​portion; the bracket 6 and the first support member 5 are snap-fitted together by the first snap-fit ​​portion and the second snap-fit ​​portion. In another embodiment of this application, the bracket 6 and the first support member 5 are bonded together with adhesive.

[0069] In one embodiment of this application, the support 6 is configured to be non-rotatable relative to the mouthpiece 2, but can slide longitudinally relative to the mouthpiece 2 along the atomizer 10.

[0070] In one embodiment of this application, such as Figure 7As shown, the nozzle 2 includes a snap-fit ​​groove 21, and at least a portion of the bracket 6 is disposed in the snap-fit ​​groove 21, allowing the bracket 6 to move within the snap-fit ​​groove 21. In one embodiment of this application, the snap-fit ​​groove 21 extends along the axial direction of the atomizer 10. When the nozzle 2 rotates from a first position to a second position, the bracket 6, under the action of the guide ramp 121 of the nozzle 2 and the housing 1, moves in both the circumferential and axial directions of the atomizer 10. The bracket 6 drives the first support member 5 to move in both the circumferential and axial directions, thereby opening and closing the liquid inlet 51.

[0071] In one embodiment of this application, such as Figure 4 As shown, the bracket 6 includes a first main body 61 and a second main body 62. The first main body 61 is connected to the first support member 5, and the second main body 62 is connected to the suction nozzle 2. The second main body 62 is disposed in the snap-fit ​​groove 21 of the suction nozzle 2.

[0072] In one embodiment of this application, the first main body 61 is fitted over the first support member 5. In another embodiment of this application, the first main body 61 is annular, and the inner diameter of the end of the first main body 61 away from the first support member 5 is smaller than the inner diameter of the end of the first main body 61 near the first support member 5, so that the first support member 5 abuts against the first main body 61, facilitating the movement of the first support member 5 by the first main body 61.

[0073] In one embodiment of this application, a reinforcing part 63 is provided between the first main body part 61 and the second main body part 62, and the reinforcing part 63 makes the connection between the first main body part 61 and the second main body part more secure.

[0074] In one embodiment of this application, such as Figure 1 As shown, a second sealing element 7 is provided between the nozzle 2 and the housing 1. The second sealing element 7 seals the gas between the housing and the nozzle 2, providing a suitable suction resistance for the user during suction. In one embodiment of this application, the nozzle 2 is provided with a first groove 24, and the second sealing element 7 is disposed in the first groove 24.

[0075] In one embodiment of this application, such as Figure 7 As shown, the nozzle 2 also includes an air tube 25 extending from the inner surface of the nozzle 2 into the interior of the nozzle 2. One end of the first support member 5 is connected to the air tube 25, allowing the aerosol generated by the atomizing component 4 to be delivered to the user through the air tube. In one embodiment of this application, the air tube 25 is also provided with reinforcing ribs, which make the structure of the air tube 25 more robust.

[0076] In one embodiment of this application, such as Figure 8As shown, 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.

[0077] In one embodiment of this application, such as Figure 1 As shown, the atomizer 10 includes a third seal 8, which is disposed inside 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.

[0078] In one embodiment of this application, such as Figure 6 As shown, 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.

[0079] 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. The positioning post 14 abuts against the third seal 8. The positioning post 14 can increase the movement resistance of the third seal 8 and prevent the third seal 8 from falling off.

[0080] In one embodiment of this application, the third seal 8 has a second through hole through which the first support 5 passes. In another embodiment, the third seal 8 has at least one second rib on its side facing the first support 5, the second rib ensuring a good seal between the third seal 8 and the first support 5. In yet another embodiment, the third seal 8 has at least one third rib on its side facing the mounting portion 13, the third rib ensuring a good seal between the third seal 8 and the mounting portion 1.

[0081] In one embodiment of this application, the third seal 8 is provided with a plurality of third through holes. The third through holes are used to position the third seal 8 with the gripper or other mechanism during the installation of the third seal 8 in the mounting part 13, so as to facilitate the automated installation of the third seal 8.

[0082] In one embodiment of this application, the suction nozzle 2 is provided with a first protrusion 22, and the housing 1 is provided with a groove 15 for receiving the first protrusion 22. The suction nozzle 2 and the housing 1 achieve relative rotation through the sliding connection of the first protrusion 22 and the groove 15.

[0083] In one embodiment of this application, such as Figure 3As shown, the outer surface of the housing 1 is provided with a first mark 16, and the outer surface of the suction nozzle 2 is provided with a second mark 23. When the suction nozzle 2 is in the first position, the first mark 16 and the second mark 23 are positioned opposite each other. In one embodiment of this application, both the first mark 16 and the second mark 23 are triangles, and when the suction nozzle 2 is in the first position, the angles of the two triangles are positioned opposite each other. In one embodiment of this application, both the first mark 16 and the second mark 23 are equilateral triangles. In one embodiment of this application, the first mark 16 and the second mark 23 may also be other shapes.

[0084] In one embodiment of this application, such as Figure 8 As shown, 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.

[0085] In one embodiment of this application, such as Figure 10 As shown, the atomizing assembly 4 includes a second support member 41, a liquid guiding member 42 located within the second support member 41, and a heating element 43. A liquid storage member 9 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 9 can prevent the liquid matrix in the liquid storage chamber 11 from leaking out of the atomizing assembly 4. In addition, the liquid storage member 9 retains a portion of the liquid matrix around the atomizing assembly 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 assembly 4. This is beneficial in preventing the atomizing assembly 4 from overheating locally due to insufficient liquid supply, which could lead to the generation of substances such as formaldehyde.

[0086] 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.

[0087] In one embodiment of this application, such as Figure 11As shown, 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 9, and has through holes through which the liquid matrix can pass. The liquid guiding component 42 has a liquid guiding surface and a heating surface arranged 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. 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] One embodiment of this application provides an aerosol generating device 100, such as... Figure 12 As shown, it includes a battery assembly 20 and the aforementioned atomizer 10, with the battery assembly 20 providing electrical power to the atomizer 10.

[0093] In one embodiment of this application, the battery assembly 20 provides electrical power to the atomizing assembly 4. In another embodiment, the DC supply voltage provided by the battery assembly 20 is in the range of about 2.5V to about 9.0V, and the DC current provided by the battery assembly 20 is in the range of about 2.5A to about 20A in amperes. Typically, the battery assembly 20 is a rechargeable battery. Alternatively, the battery assembly 20 may be another form of charge storage device, such as a capacitor. The battery assembly 20 may require recharging and may have a capacity that allows for storing sufficient energy for one or more aspirations; for example, the battery assembly 20 may have sufficient capacity to allow continuous aerosol generation over a predetermined period of time. In another example, the battery assembly 20 may have sufficient capacity to allow the activation of a predetermined number of aerosol generating devices.

[0094] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
