DETAILED DESCRIPTION

[0023] The present application is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood.

This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0024] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0025] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0026] like Figures 1 to 4 As shown, the present application provides an atomization device, which includes an atomizer 1 and a power supply module 2. The atomizer 1 can realize atomization of an aerosol-generating substrate under the power supply of the power supply module 2.

[0027] The nebulizer 1 may include an atomizing assembly 10. The atomizing assembly 10 defines an airflow channel 100 for atomizing an aerosol-generating substrate to generate an aerosol for inhalation by a user through the airflow channel 100. The nebulizer 1 also defines a liquid storage chamber 30 for storing a liquid aerosol-generating substrate to be atomized.

[0028] The atomizer assembly 10 includes a housing 11, an atomizer bracket 12, and a seal 16. The housing 11 includes an atomizer nozzle 111, which defines an air outlet channel 1111. The atomizer bracket 12 defines an atomizer channel 123, which communicates with the air outlet channel 1111. The seal 16 is disposed between the housing 11 and the atomizer bracket 12 to seal at least a portion of the connection between the two, while ensuring that the air outlet channel 1111 and the atomizer channel 123 are in communication and sealed from the outside world.

[0029] The liquid storage chamber 30 is used to provide an aerosol-generating substrate to the atomizing assembly 10, and the top of the liquid storage chamber 30 is higher than the top of the atomizing channel 123. The aerosol-generating substrate in the liquid storage chamber 30 can flow into the atomizing channel 123 under the action of gravity, be heated and atomized, and generate an aerosol.

[0030] It should be understood that the atomization channel 123 and the air outlet channel 1111 can together constitute the air flow channel 100 of the atomizer 1 .

[0031] The direction of the atomizing nozzle 1 relative to the atomizing assembly 10 is top, top or up, above; the opposite direction is bottom, bottom or down, below. Figure 3 and Figure 4The angles shown are based on the extension direction of the axis L. Figure 3 and Figure 4 In the angle shown, “the top end of the liquid storage chamber 30 is higher than the top end of the atomization channel 123 ” can be understood as the upper end of the liquid storage chamber 30 is located above the upper end of the atomization channel 123 .

[0032] It should be understood that there is currently an atomizer 1 whose air outlet channel 1111 is defined by components outside the atomizing nozzle 111. Such a setting causes the atomizer 1 to have the problem of liquid leakage (atomized liquid and / or condensed liquid) after assembly, and there will also be leakage of aerosol during the suction process. Therefore, it is necessary to set a porous liquid absorbent part in the cavity around the atomizing nozzle 111 to absorb the leaked atomized liquid, condensed liquid, etc., and at the same time absorb the aerosol in the airflow. Such a setting method greatly reduces the user's suction taste and usage experience.

[0033] In this application, at least a portion of the structure of the atomizer bracket 12 is engaged with the inner wall of the housing 11 via a seal 16, effectively sealing the connection between the housing 11 and the atomizer bracket 12 to prevent liquid leakage. This also isolates the atomizer channel 123 and the air outlet channel 1111 from the outside world, preventing gas and liquid leakage at the connection between the atomizer channel 123 and the air outlet channel 1111. Furthermore, leakage of aerosol within the airflow channel 100 is prevented.

[0034] The present application sets the top of the liquid storage chamber 30 to be higher than the top of the atomization channel 123, thereby allowing the aerosol-generating substrate in the liquid storage chamber 30 to automatically flow into the atomization channel 123 under the action of gravity. In other words, the smoothness of the liquid flow can be improved, the occurrence of dry burning can be reduced, and the user experience can be improved.

[0035] In some embodiments, the liquid storage chamber 30 can be operably connected to the atomization channel 123. The aerosol-generating substrate in the liquid storage chamber 30 can flow into the atomization channel 123 under the action of gravity, where it is heated and atomized to generate an aerosol. The liquid storage chamber 30 can also be in a state of constant communication with the atomization channel 123 to ensure that the liquid storage chamber 30 can provide the aerosol-generating substrate to the atomization assembly 10 at any time.

[0036] In some embodiments, the atomizing assembly 10 further includes a heating assembly 13 disposed within the atomizing channel 123 for heating the aerosol-generating substrate to atomize it into an aerosol. The atomizing bracket 12 may further include a liquid guide hole 121 that connects the liquid storage chamber 30 to the atomizing channel 123.

[0037] The heating assembly 13 may include a heating body 131 and at least two heating electrodes 132. The heating electrodes 132 are used to connect to a power source and are electrically connected to the heating body 131 so that the heating body 131 can heat the atomized aerosol-generating substrate when powered on.

[0038] During use, the aerosol-generating substrate in the liquid storage chamber 30 can flow under the action of gravity through the liquid guide hole 121 to the heating component 13 in the atomization channel 123, where it is heated and atomized by the heating component 13 to form an aerosol. The aerosol can follow the airflow generated by the user's inhalation, pass through the atomization channel 123 and the air outlet channel 1111, and flow out of the atomization nozzle 111 for inhalation by the user.

[0039] In some embodiments, the heating body 131 is cylindrical and is disposed on the atomizing bracket 12 and is located in the circumference of the atomizing channel 123. The number of the heating electrodes 132 is three.

[0040] In some embodiments, the heating body 131 may also be in a spiral, block, sheet, filament, or other shaped structure. When it is in sheet form, it may be a heating net or a heating sheet, which is not specifically limited here. When it is in a spiral form, it may be formed by spirally winding a heating wire, which is also not limited here. The number of the heating electrodes 132 may also be three, four, or the like.

[0041] Continue reading Figure 3 and Figure 4 In some embodiments, the liquid storage chamber 30 may include a first liquid storage chamber 31 and a second liquid storage chamber 32. The first liquid storage chamber 31 and the second liquid storage chamber 32 are operably connected. The first liquid storage chamber 31 is located at the top of the second liquid storage chamber 32, and the second liquid storage chamber 32 is operably connected to the atomization channel 123 through the liquid guide hole 121.

[0042] By dividing the liquid storage chamber 30 into a first liquid storage chamber 31 and a second liquid storage chamber 32, which are operably connected to each other, the flow rate of liquid supplied from the liquid storage chamber 30 to the atomization channel 123 can be effectively controlled. The second liquid storage chamber 32 can serve as a chamber for temporarily storing liquid aerosol-generating substrate, thereby preventing the aerosol-generating substrate from automatically supplying liquid to the atomization channel 123 too quickly under the action of gravity, which could lead to leakage or explosion.

[0043] By positioning the first liquid storage chamber 31 at the top of the second liquid storage chamber 32 and operatively connecting the second liquid storage chamber 32 to the atomization channel 123, the relative connection and blockage between the first liquid storage chamber 31, the second liquid storage chamber 32, and the atomization channel 123 can be flexibly controlled during use. The aerosol-generating substrate can be pre-flowed from the first liquid storage chamber 31 into the second liquid storage chamber 32. The aerosol-generating substrate in the second liquid storage chamber 32 can then be controlled to flow into the atomization channel 123, thereby improving control over the flow rate of the aerosol-generating substrate.

[0044] The volume of the second liquid storage chamber 32 can be roughly selected as a smaller capacity such as 1ml, 1.5ml, 2ml, etc., and the volume of the first liquid storage chamber 31 can be roughly selected as a larger capacity such as 8ml, 10ml, 12ml, etc., so as to achieve flow rate control through the volume difference between the two.

[0045] In some embodiments, the liquid guide hole 121 can be positioned so as to correspond to the upstream position (or even the upstream end) of the atomization channel 123. It can also correspond to the bottom end of the second liquid storage chamber 32 to ensure that the liquid in the second liquid storage chamber 32 can be completely discharged, thereby avoiding waste of aerosol-generating substrate.

[0046] It should be understood that, with respect to "upstream" and "downstream", the position passed first is the upstream position, and the position passed later is the downstream position, based on the flow direction of the gas in the airflow channel 100. Figure 3 and Figure 4 In the position shown, the air outlet channel 1111 is located at the top of the atomizing channel 123 and downstream of the atomizing channel 123. The liquid guide hole 121 is provided at the bottom of the atomizing channel 123 and upstream of the atomizing channel 123.

[0047] In some embodiments, the liquid guide hole 121 may also be provided at other positions of the atomizing bracket 12. For example, it may correspond to the midstream or downstream section of the atomizing channel 123.

[0048] During use, if Figure 3 As shown, the second liquid storage chamber 32 can be controlled to communicate with the first liquid storage chamber 31, and the second liquid storage chamber 32 can be controlled to be blocked from the atomization channel 123 (the liquid guide hole 121 is blocked). The aerosol-generating substrate in the first liquid storage chamber 31 can move into the second liquid storage chamber 32 under the action of gravity.

[0049] For example Figure 4 As shown, the first liquid storage chamber 31 and the second liquid storage chamber 32 can be relatively blocked, and the second liquid storage chamber 32 can be connected to the atomization channel 123. The aerosol-generating substrate in the second liquid storage chamber 32 can move into the atomization channel 123 under factors such as negative pressure and gravity.

[0050] In some embodiments, the second liquid storage chamber 32 may not be provided, so that the first liquid storage chamber 31 is directly and blockably connected to the atomization channel 123. Alternatively, the second liquid storage chamber 32 may be provided so as to be always connected to the first liquid storage chamber 31 and blockably connected to the atomization channel 123. Alternatively, the second liquid storage chamber 32 may be provided so as to be always connected to the atomization channel 123 and blockably connected to the first liquid storage chamber 31.

[0051] In some embodiments, the second liquid storage chamber 32 may also be disposed between the first liquid storage chamber 31 and the atomizing channel 123, and the three may be disposed adjacent to each other in the horizontal direction. When the axis of the atomizing channel 123 does not coincide with the axis of the air outlet channel 1111 (there is an angle, for example, a vertical arrangement), the first liquid storage chamber 31, the second liquid storage chamber 32, and the atomizing channel 123 may also be disposed adjacent to each other in the height direction from top to bottom.

[0052] In some embodiments, the atomizer assembly 10 may further include a liquid conduction switch 17 movably disposed between the housing 11 and the atomizer bracket 12 for controlling the conduction and blocking between the second liquid storage chamber 32 and the atomization channel 123 and the first liquid storage chamber 31 .

[0053] The liquid guide switch 17 includes a first position and a second position along its movement path. When the liquid guide switch 17 is in the first position, the first liquid storage chamber 31 is in communication with the second liquid storage chamber 32, and the second liquid storage chamber 32 is sealed from the atomization channel 123 (i.e., the liquid guide hole 121 is blocked). When the liquid guide switch 17 is in the second position, the atomization channel 123 is in communication with the second liquid storage chamber 32, and the second liquid storage chamber 32 is sealed from the first liquid storage chamber 31 (is blocked).

[0054] The arrangement of the liquid guide switch 17 can realize the separate switch control of the two connection holes by controlling one component, thereby reducing the number of switch components and improving the user experience.

[0055] It should be understood that the movement of the liquid guide switch 17 can be achieved through manual adjustment by the user, or can be achieved through electronic control such as electromagnetic means, etc. No specific limitation is given here.

[0056] In some embodiments, the number of the liquid conduction switches 17 can also be set to two, which can separately control the conduction / closure of the first liquid storage chamber 31 and the second liquid storage chamber 32, and the conduction / closure of the second liquid storage chamber 32 and the atomization channel 123.

[0057] like Figure 3 and Figure 4As shown, in some embodiments, the atomizing assembly 10 may further include a liquid guide 14 for conducting the liquid aerosol-generating substrate. The liquid guide 14 may be disposed in the atomizing support 12 and located in the atomizing channel 123 .

[0058] The liquid guide 14 is substantially cylindrical with two ends connected therethrough and is disposed on the side wall of the atomizing channel 123. The heating assembly 13 is disposed on the inner wall of the liquid guide 14.

[0059] In some embodiments, the cylindrical heating element 131 is positioned in contact with the inner wall of the cylindrical liquid-guiding member 14. The liquid-guiding member 14 is positioned within the atomizing channel 123 such that the outlet of the first liquid storage chamber 31 is higher than at least a portion of the liquid-guiding member 14. This arrangement facilitates the automatic flow of the aerosol-generating substrate within the second liquid storage chamber 32 at the bottom end of the first liquid storage chamber 31 to the liquid-guiding member 14.

[0060] Further, in Figure 3 and Figure 4 In the angle shown, the first liquid storage chamber 31 corresponds to the air outlet channel 1111 in the extension direction along the axis L, and the second liquid storage chamber 32 corresponds to at least part of the atomization channel 123 in the extension direction along the axis L.

[0061] During inhalation, the liquid aerosol-generating substrate flows from the liquid storage chamber 30 into the liquid guide 14 and, under the action of negative pressure (and / or suction), gradually approaches the heating element 131. It is heated and atomized by the heating element 131, generating an aerosol. The aerosol mixes with air to form a mixed gas, which then flows out through the air outlet channel 1111.

[0062] It should be understood that the liquid-conducting member 14 can be made of a porous material, such as porous ceramics, porous cotton, etc., which is not specifically limited here.

[0063] In some embodiments, the liquid guide 14 may also be configured in other shapes such as a block, or may be configured only on one side of the heating body 131 .

[0064] In some embodiments, the first liquid storage chamber 31 may also correspond to at least a portion of the air outlet channel 1111 and / or a portion of the atomization channel 123 .

[0065] In this embodiment, the atomizer 1 further includes a liquid storage member 20. The liquid storage member 20 defines a first liquid storage chamber 31, and the atomizing assembly 10 defines a second liquid storage chamber 32. The liquid storage member 20 is detachably connected to the atomizing assembly 10.

[0066] By providing a separate liquid storage member 20 and detachably connecting it to the atomizer assembly 10, the user can replace the liquid storage member 20 during use. During use, if all the aerosol-generating substrate in the first liquid storage chamber 31 has been atomized, the liquid storage member 20 can be removed and replaced with a new one. Alternatively, the liquid storage member 20 can be removed and new aerosol-generating substrate can be added to the first liquid storage chamber 31.

[0067] In some embodiments, the liquid storage member 20 can be relatively fixedly disposed with respect to the atomizer assembly 10. In this embodiment, an opening can be provided on the liquid storage member 20. If the aerosol-generating substrate is exhausted during use, new aerosol-generating substrate can be added to the first liquid storage chamber 31 through the opening.

[0068] like Figure 3 and Figure 4 As shown, in some embodiments, the housing 11 may further include a main body 112. The main body 112 is connected to the atomizing nozzle 111 to form an integral structure, and is also connected to the atomizing bracket 12. The atomizing bracket 12 may be disposed in the housing 11.

[0069] It should be understood that the main body 112 and the atomizing nozzle 111 can be integrally formed, or can be relatively fixedly arranged by a connector, adhesive bonding, or can be detachably connected, etc. No specific limitation is given here.

[0070] The atomizing nozzle 111 may include a connecting portion and an air guide portion. The air guide portion may be cylindrical with both ends extending through it, defining an air outlet channel 1111. The connecting portion may also be cylindrical and arranged around the circumference of the air guide portion to form an outer shell of the atomizing nozzle 111. The air guide portion may be engaged with at least part of the structure of the atomizing bracket 12 via a sealing member 16. The connecting portion may be connected to the main body 112.

[0071] It should be understood that the air guide portion and the connection portion of the atomizing nozzle 111 can be integrally formed, or relatively fixedly arranged by a connector, adhesive bonding, or detachably connected, etc. No specific limitation is given here.

[0072] See also Figure 1 and Figure 2 As shown, the liquid storage component 20 is detachably connected to the housing 11 to achieve detachable connection between the liquid storage component 20 and the atomization assembly 10 .

[0073] In one embodiment, the housing 11 is generally L-shaped, and the atomizer bracket 12 is located at the bottom end (the horizontal side of the L) of the housing 11. The liquid storage member 20 is generally cubical and is located in the L-shaped notch of the housing 11. When assembled with the generally L-shaped housing 11, the entire atomizer 1 can be generally cubical.

[0074] The second liquid storage chamber 32 is located approximately in the L-shaped horizontal portion of the housing 11 and is defined by the top of the atomizing bracket 12 and the top wall of the L-shaped horizontal portion of the housing 11. The liquid storage member 20 is located at the top of the second liquid storage chamber 32.

[0075] A through hole may be formed on the top wall of the L-shaped horizontal portion of the housing 11 to allow communication between the first liquid storage chamber 31 and the second liquid storage chamber 32. The outlet of the liquid storage member 20 is detachably disposed within the through hole, and a seal may be provided between the two to provide an interference fit to prevent leakage.

[0076] In some embodiments, the housing 11 may also be in other shapes such as cylindrical, polygonal, spherical, irregular, etc. In some embodiments, the atomizing bracket 12 may also be disposed at other locations (such as one side) within the housing 11 .

[0077] The liquid storage member 20 may also be in other shapes such as cylindrical, polygonal, irregular, spherical, hemispherical, etc. After the liquid storage member 20 is assembled with the housing 11 , the atomizer 1 as a whole may also be in other shapes such as cylindrical, polygonal, irregular, spherical, hemispherical, etc.

[0078] See also Figure 2 In some embodiments, the housing 11 may further include an air inlet 113 that communicates with the atomization channel 123. The air inlet 113, the atomization channel 123, and the air outlet channel 1111 may be sequentially connected end to end to form an airflow channel 100 that is open at both ends. During the user's inhalation process, gas enters the atomizer 1 through the air inlet 113 and mixes with the atomized aerosol in the atomization channel 123 to form a mixed gas, which ultimately flows out through the air outlet channel 1111.

[0079] In some embodiments, the airflow channel 100 may further include an air inlet channel (not shown). Based on the airflow direction, the upstream end of the air inlet channel is connected to the air inlet hole 113, and the downstream end is connected to the upstream end of the atomization channel 123. The downstream end of the atomization channel 123 is connected to the upstream end of the air outlet channel 1111. The downstream end of the air outlet channel 1111 is connected to the atomization nozzle 111.

[0080] Continue reading Figure 3 and Figure 4 In this embodiment, the air outlet channel 1111 and the atomization channel 123 are coaxially arranged and are both located at the vertical edge of the L-shaped shell 11, so that the air flow channel 100 is located on one side of the liquid storage chamber 30.

[0081] It should be understood that after the airflow is heated by the heating assembly 13 through the atomization channel 123, it changes from a normal temperature airflow to a high temperature airflow. The heat transfer between the airflow and the solid wall also affects the liquid aerosol-forming substrate within the first liquid storage chamber 31. The high temperature environment may cause the ester substance in the aerosol-forming substrate within the first liquid storage chamber 31 to decompose and destroy.

[0082] By arranging the airflow channel 100 on one side of the liquid storage chamber 30 , the adjacent area between the airflow channel 100 and the first liquid storage chamber 31 can be reduced, thereby reducing the impact of the high temperature after heating and atomization on the aerosol-generating matrix in the first liquid storage chamber 31 .

[0083] In some embodiments, the air outlet channel 1111, the atomization channel 123, and the air inlet channel can be coaxially arranged, or at least one section can be non-coaxially arranged with the other sections. Each section of the three can be straight or curved.

[0084] In some embodiments, the housing 11 may further define a first cavity 114 , which is located around at least a portion of the air outlet channel 1111 . When the liquid storage member 20 is assembled with the housing 11 , the first liquid storage chamber 31 is located on one side of the first cavity 114 .

[0085] By providing the first cavity 114 around at least a portion of the circumference of the air outlet channel 1111, a spacer can be provided. In addition to the solid wall, a cavity also exists between the air outlet channel 1111 and the first liquid storage chamber 31 to provide thermal insulation. This further reduces the transfer of heat from the airflow channel 100 to the liquid storage chamber 30, thereby further reducing the impact of high temperatures on the aerosol-generating substrate within the liquid storage chamber 30.

[0086] In some embodiments, the first cavity 114 is located at the top of the atomizer bracket 12 and surrounds at least a portion of the air outlet channel 1111. The length of the area enclosed by the first cavity 114 in the axial direction of the air outlet channel 1111 can be adapted to the length of the side wall adjacent to the liquid storage component 20 and the housing 11 in the axial direction of the air outlet channel 1111.

[0087] In some embodiments, the first cavity 114 may also be disposed around the air outlet channel 1111 and at least a portion of the atomization channel 123 .

[0088] In some embodiments, the first cavity 114 may be located only on one side of the air flow channel 100 close to the first liquid storage chamber 31. That is, the first cavity 114 is only provided between the first liquid storage chamber 31 and the air flow channel 100 to reduce the volume of the atomizer 1.

[0089] In some embodiments, the atomizing bracket 12 may further define a second cavity 122 . The second cavity 122 is communicated with the atomizing channel 123 to provide expansion space for the liquid guide 14 .

[0090] It should be understood that since the liquid-guiding member 14 absorbs and conducts liquid aerosol-forming substrate, it may deform in some embodiments after absorbing liquid. The provision of a second cavity 122 connected to the atomization channel 123 provides space for the liquid-guiding member 14 to expand, ensuring that it can absorb sufficient aerosol-forming substrate. During the puffing process, a liquid-guiding member 14 that absorbs sufficient aerosol-forming substrate can better prevent dry burning.

[0091] In some embodiments, the atomizing bracket 12 may be formed with a longitudinal through hole (or through groove), the length of which is parallel to the axial direction of the atomizing channel 123 and is greater than or equal to the axial length of the liquid guide 14, so that the liquid guide 14 can expand through the through hole (or through groove).

[0092] In some embodiments, the second cavity 122 is located on a side of the atomizing channel 123 away from the first liquid storage chamber 31. Such a configuration can provide a clearance space for the communication between the first liquid storage chamber 31 and the atomizing channel 123.

[0093] In some embodiments, the second cavity 122 is located at a bottom end of a portion of the first cavity 114 .

[0094] In some embodiments, the second cavity 122 may also be located at other positions on the circumference of the atomization channel 123 , and the location thereof should not affect the communication between the first liquid storage cavity 31 and the atomization channel 123 .

[0095] In some embodiments, the atomizing assembly 10 may further include at least one liquid absorbing member 15 , which is disposed at the bottom end of the atomizing bracket 12 and blocks the second cavity 122 .

[0096] It should be understood that since the liquid guide 14 expands into the second cavity 122 after absorbing the aerosol-generating substrate, the absorbed aerosol-generating substrate may flow out during the expansion process. The aerosol-generating substrate that flows out due to squeezing may potentially leak out along the second cavity 122.

[0097] The provision of the liquid absorbing member 15 can effectively prevent the liquid aerosol-generating matrix from leaking out during the flow process, thereby improving the cleanliness of the atomizer 1 and indirectly increasing the service life of the atomizer 1.

[0098] It should be understood that during the suction process, cold air (relatively speaking) is prone to condensation when passing through the high-temperature atomization channel 123. Therefore, the arrangement of the liquid absorbing member 15 can also absorb the condensation and prevent the condensation from seeping out.

[0099] In one embodiment, the liquid absorbing member 15 is located at the bottom end of the entire atomizing support 12. That is, it is located at the bottom end inside the housing 11 and substantially covers the bottom end of the housing 11.

[0100] The number of the liquid absorbing members 15 can be set to at least two to improve the liquid absorbing effect.

[0101] In one embodiment, the number of the liquid absorbing members 15 is two, which are respectively defined as a first liquid absorbing member 151 and a second liquid absorbing member 152. The first liquid absorbing member 151 and the second liquid absorbing member 152 are at least partially overlapped and filled between the atomizing bracket 12 and the bottom wall of the housing 11.

[0102] In some embodiments, a separate absorbent member 15 may be provided solely for sealing the second cavity 122 to prevent liquid from leaking out of the second cavity 122. At least one absorbent member 15 may also be provided at other locations outside the second cavity 122, either as a whole or separately.

[0103] It should be understood that the liquid absorbing member 15 can be a tank capable of temporarily storing liquid. It can also be configured as a porous solid structure with liquid absorbing ability (such as a porous structure made of cotton or ceramic materials, etc.). No specific limitation is made here.

[0104] In some embodiments, the second liquid storage chamber 32 can be provided corresponding to the second cavity 122, respectively, on opposite sides of the atomizer bracket 12, and arranged together around the circumference of the atomizer channel 123. This arrangement can reduce the transfer of heat from the atomizer channel 123 to the sidewalls of the housing 11, prevent the atomizer 1 from overheating during use, and improve the user's grip experience.

[0105] The second liquid storage chamber 32 can also be configured to be roughly L-shaped, with the vertical portion of the L-shaped portion extending in parallel with the axial direction of the atomization channel 123. The length thereof in the axial direction of the atomization channel 123 can be adapted to the length of the second cavity 122 in the axial direction of the atomization channel 123.

[0106] It should be understood that, due to the effect of gravity, after the aerosol-generating substrate in the first liquid storage chamber 31 flows into the second liquid storage chamber 32 , it will fill the L-shaped horizontal portion in the second liquid storage chamber 32 .

[0107] By configuring the second liquid storage chamber 32 in an L-shape, the vertical portion at the top of the L-shape can also form a cavity when the aerosol-generating substrate is contained, thereby acting as a partition. This structural arrangement can further reduce the impact of high-temperature airflow on the liquid aerosol-generating substrate, thereby ensuring a pleasant puffing experience for the user.

[0108] In some embodiments, the L-shaped vertical portion of the second liquid storage chamber 32 and the second cavity 122 are located at the bottom end of a portion of the first cavity 114, and the two are arranged corresponding to the first cavity 114. The first liquid storage chamber 31 is located at the top of the L-shaped horizontal portion of the second liquid storage chamber 32.

[0109] In one embodiment, the length of the first cavity 114 defined by the housing 11 and the sealing member 16 is 0.25 to 0.5 times the length of the atomizer. Since the first cavity 114 is a sealed cavity, it is convenient to place decorative elements or create decorative surfaces in the first cavity 114. For example, decorative stickers, spray-painted or laser-engraved decorative patterns, or LED lights can be placed.

[0110] In some embodiments, the length of the second cavity 122 in the axial direction of the atomization channel 123 may be greater than or less than the length of the L-shaped vertical portion of the second liquid storage chamber 32 in the axial direction of the atomization channel 123. The second cavity 122 and the L-shaped vertical portion of the second liquid storage chamber 32 may not be located on opposite sides of the atomization channel 123, and the two may be adjacent to each other in the circumferential direction of the atomization channel 123.

[0111] In some embodiments, the second liquid storage chamber 32 can also be configured as a non-L-shaped columnar structure without a vertical protrusion. A separate cavity can be formed by the atomizer bracket 12 at the corresponding L-shaped vertical protrusion to achieve a spacing effect. The second liquid storage chamber 32 can also be configured as other shapes to correspond to embodiments with other positional relationships between the first liquid storage chamber 31, the second liquid storage chamber 32, and the atomizer channel 123.

[0112] In some embodiments, the atomizer assembly 10 further includes a positioning member 18, which is disposed at the bottom end of the liquid guide member 14 and is used to fix the heating electrode 132. The bottom end of the heating electrode 132 can extend downward through the positioning member 18 for connecting to a power source.

[0113] In one embodiment, the positioning member 18 is cylindrical, and its outer wall is substantially gear-shaped.

[0114] like Figure 1 and Figure 2 As shown, in this embodiment, a sliding groove structure is formed on the side wall of the liquid storage member 20 and the side wall of the housing 11, and the two are detachably connected by sliding.

[0115] In some embodiments, the two can also be detachably connected by setting a snap-fit structure or other methods.

[0116] In some embodiments, at least part of the bottom wall of the first liquid storage chamber 31 can also be set to an inclined shape, so that during the liquid discharge process, the aerosol generating matrix in the first liquid storage chamber 31 can slide down along the inclined bottom wall to the outlet of the liquid storage component 20 by gravity, thereby reducing the retention of the aerosol generating matrix in the first liquid storage chamber 31.

[0117] In some embodiments, the liquid storage element 20 may be configured in a triangular column shape, a funnel shape, or the like, which may also reduce the retention of the aerosol-generating matrix in the first liquid storage chamber 31 .

[0118] In some embodiments, the bottom wall of the second liquid storage chamber 32 may also be configured as an inclined structure so that the aerosol generating substrate in the second liquid storage chamber 32 can smoothly move into the liquid guiding member 14 .

[0119] like Figure 3 and Figure 4 As shown, in some embodiments, the power supply module 2 may include a housing 201 and a power supply assembly 202 disposed within the housing 201. The housing 201 may be detachably connected to the outer shell 11 of the atomizer 1. When the atomizer 1 or the power supply module 2 malfunctions, it can be disassembled and replaced.

[0120] In some embodiments, the housing 201 may also be integrally formed with or fixedly connected to the outer shell 11 to ensure a stable electrical connection between the power supply module 2 and the atomizer 1 .

[0121] The power supply component 202 can be electrically connected to the heating electrode 132 , and can be electrically connected to the heating body 131 through the heating electrode 132 to supply power to the heating body 131 .

[0122] In this embodiment, the heating electrode 132 is electrically connected to the power supply assembly 202 through hard contact.

[0123] It should be understood that the atomizing device constructed in the present application is only one of the applications of the atomizer 1. The description of the atomizing device should not be regarded as limiting the atomizer 1 constructed in the present application.

[0124] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For those skilled in the art of the present application, based on the concept of the present application, they can also make some simple deductions, modifications or substitutions.
