[0031] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various implementation manners. At the same time, the steps or actions in the method description can also be reordered or adjusted in an obvious manner by those skilled in the art.

And the "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connection (coupling).

[0033] In the embodiments of the present application, in order to solve the problems in the prior art that the battery in the aerosol generating device is welded to the circuit board 22 to provide power for the operation of the aerosol generating device, resulting in inconvenient battery installation and difficult disassembly and repair, an atomizing device is provided. Please refer to Figure 1-4 As shown, the atomizing device 1 includes:

[0034] The atomization component 2 includes an atomization core 21, a circuit board 22, and elastic electrodes 23. The atomization core 21 is used to heat an aerosol matrix to generate an aerosol; the elastic electrodes 23 are fixed to the circuit board 22;

[0035] The battery component 3 includes a battery body 31 and contact electrodes 32. The contact electrodes 32 are electrically connected to the battery body 31; the elastic electrodes 23 are elastically contact-connected to the contact electrodes 32; the elastic electrodes 23 can be elastically compressed and deformed under the pressing of the contact electrodes 32;

[0036] The limiting component 5 is arranged between the atomization component 2 and the battery component 3 and is used to form a preset gap between the atomization component 2 and the battery component 3; the size of the preset gap in the height direction is between the minimum working size and the maximum working size of the elastic electrodes 23 in the height direction.

[0037] The atomization device 1 in the embodiment of the present application is used to heat an aerosol matrix to generate an aerosol. Among them, the atomization device 1 includes an atomization component 2, and the structure for heating in the atomization component 2 is the atomization core 21. In order to energize the atomization core 21 to work, a battery component 3 is provided in the embodiment of the present application to provide power for the atomization core 21.

[0038] To achieve the electrical connection between the atomization component 2 and the battery component 3, please continue to refer to Figure 2-4 As shown, the atomization component 2 includes a circuit board 22 and elastic electrodes 23. Among them, an electrical connection is formed between the elastic electrodes 23 and the atomization core 21 through the circuit board 22, that is, an electrical connection is formed between the corresponding pins of the atomization core 21 and the elastic electrodes 23. This part usually includes the elastic electrodes 23 corresponding to the positive and negative pins. Therefore, the number of elastic electrodes 23 is generally configured to be at least two. An electrical connection is formed between the atomization core 21 and the circuit board 22. The atomization core 21 can be electrically connected to the circuit board 22 through a wiring harness. The wiring harness can be a flexible wire. Therefore, a fixed connection may not be directly formed between the atomization core 21 and the circuit board 22, and a fixed connection can be formed through the housing component 7 of the atomization device 1.

[0039] The battery component 3 for providing power includes a battery body 31 and contact electrodes 32. Among them, the battery body 31 can be a disposable battery cell type or a rechargeable battery cell type. The structure of the battery body 31 can include a soft-pack battery cell and a battery cell housing fixedly arranged around the soft-pack battery cell. The battery cell housing can provide protection for the soft-pack battery cell.

[0040] In order to supply the power of the battery body 31 to the outside, the battery assembly 3 is provided with a contact electrode 32, and the contact electrode 32 is electrically connected to the battery body 31. The contact electrode 32 and the elastic electrode 23 are oppositely arranged in the height direction, and a contact electrical connection can be formed between the elastic electrode 23 and the contact electrode 32, so there is no need to form a connection by welding. In addition, it is worth mentioning that, for the sake of convenience of description, the height direction in the embodiments of the present application refers to the connection direction between the atomizing assembly 2 and the battery assembly 3.

[0041] To ensure the reliability of the contact electrical connection formed between the elastic electrode 23 and the contact electrode 32, please continue to refer to Figure 2-4 As shown, the elastic electrode 23 abuts against the contact electrode 32 to form an electrical contact connection, and the elastic electrode 23 can be elastically compressed and deformed under the pressure of the contact electrode 32. That is to say, the elastic electrode 23 can undergo elastic deformation under the pressure of the contact electrode 32. When elastic deformation is generated due to the pressure, the elastic electrode 23 has an elastic tendency to return to its original state. Therefore, the elastic electrode 23 will be tightly connected to the contact electrode 32 under the action of elastic deformation, thereby ensuring the reliability of the electrical connection between the elastic electrode 23 and the contact electrode 32. Among them, the elastic electrode 23 can specifically be an elastic electrical connector such as an elastic thimble, and the contact electrode 32 can be a fixed conductive part including a pad and a metal contact.

[0042] Since the electrical connection between the elastic electrode 23 and the contact electrode 32 is formed based on contact, in order to prevent damage to the elastic electrode 23 when the atomizing assembly 2 and the battery assembly 3 are connected, such as the elastic electrode 23 being bent due to too small a gap between the circuit board 22 and the battery body 31 or being elastically deformed due to excessive extrusion, please continue to refer to Figure 2-4As shown, the atomizing device 1 further includes a limiting component 5. The limiting component 5 is arranged between the atomizing component 2 and the battery component 3 and is used to form a preset gap between the atomizing component 2 and the battery component 3. The preset gap refers to the interval between the circuit board 22 and the battery body 31. The purpose of setting this preset gap is that when the atomizing component 2 is fixedly connected to the battery component 3, it can not only make the elastic electrode 23 elastically contact the contact electrode 32, but also prevent the elastic electrode 23 from being damaged due to excessive compression. Therefore, the size of the preset gap needs to be set within a certain range. The range of the preset gap is that its size in the height direction is between the minimum working size and the maximum working size of the elastic electrode 23 in the height direction. Among them, the maximum working size refers to the size of the elastic electrode 23 after the minimum amount of compression, usually the size in the non-compressed state, and this size is larger than the size of the preset gap; the minimum working size refers to the size of the elastic electrode 23 after the maximum amount of compression, and this size represents the minimum size of the elastic electrode 23 in the extreme compression state, and this size is smaller than the size of the preset gap. Therefore, since the preset gap is smaller than the maximum working size of the elastic electrode 23, the preset gap will not affect the contact between the elastic electrode 23 and the contact electrode 32 to achieve electrical connection; and since the preset gap is larger than the minimum working size of the elastic electrode 23, the preset gap will limit the excessive deformation of the elastic electrode 23, thereby avoiding the rigid contact between the elastic electrode 23 and the battery component 3 due to excessive compression, resulting in the circuit board 22 being bent or even damaged, or the elastic electrode 23 itself being damaged due to excessive compression.

[0043] In some alternative embodiments, such as Figure 3As shown, in order to limit the position between the atomization component 2 and the battery component 3 through the limiting component 5, so as to form a preset gap between the circuit board 22 and the battery body 31, the limiting component 5 may specifically include a first limiting member 51 and a second limiting member 52. The first limiting member 51 is fixedly arranged on the atomization component 2, and the second limiting member 52 is fixedly arranged on the battery component 3. That is to say, the limiting component 5 is composed of two parts, namely the first limiting member 51 fixedly connected to the atomization component 2 and the second limiting member 52 fixedly connected to the battery component 3. The first limiting member 51 and the second limiting member 52 are in contact with each other, so that the first limiting member 51 and the second limiting member 52 limit each other's positions, thereby realizing the formation of a preset gap between the circuit board 22 and the battery body 31. The first limiting member 51 and the second limiting member 52 are separated from each other, which can improve the design and assembly freedom of the first limiting member 51 and the second limiting member 52. For example, different sizes of preset gaps can be realized by separately adjusting the materials and sizes of the first limiting member 51 or the second limiting member 52, and the first limiting member 51 and the second limiting member 52 can be made of different materials, and the first limiting member 51 and the second limiting member 52 can each reuse the structures of other components in the atomization device 1. For example, the atomization component 2 further includes a housing component 7, and the housing component 7 includes structural members for forming various chambers. The first limiting member 51 can be formed in these structural members, including the pneumatic switch mounting seat for forming the pneumatic switch induction chamber, the housing for forming the liquid storage chamber for storing the aerosol matrix, etc., or can be directly formed on the circuit board 22 and fixedly connected to the circuit board 22. The same is true for the second limiting member 52, which can be formed in the corresponding structural member of the battery component 3.

[0044] In some alternative embodiments, please continue to refer to Figure 3, the size of the preset gap itself is not necessarily fixed; in order to adapt to more installation environments, such as adapting to elastic electrodes 23 of different sizes, and at the same time preventing rigid contact between the first limiting member 51 and the second limiting member 52 from causing damage, the material hardness of one of the first limiting member 51 and the second limiting member 52 can be higher than that of the other, and the first limiting member 51 and the second limiting member 52 are in contact with each other, so that a preset gap is formed between the atomizing assembly 2 and the battery assembly 3. Since the material hardness of one of the first limiting member 51 and the second limiting member 52 is higher than that of the other, for example, the material hardness of the first limiting member 51 is higher than that of the second limiting member 52, the second limiting member 52 can provide buffering for the first limiting member 51, so that the contact distance between the first limiting member 51 and the second limiting member 52 can be adjusted. On the one hand, it can avoid damage to the first limiting member 51 and the second limiting member 52 that may be caused by rigid contact between the first limiting member 51 and the second limiting member 52. On the other hand, it can realize the change of the gap between the first limiting member 51 and the second limiting member 52, so that the preset gap formed between the circuit board 22 and the battery body 31 is adjustable. Among them, the second limiting member 52 can specifically be made of a flexible structure such as EVA foam that can deform.

[0045] In some alternative embodiments, in order to protect the contact electrode 32 and at the same time improve the uniformity of the preset gap, the second limiting member 52 can be arranged in a ring shape, and the second limiting member 52 is arranged around the contact electrode 32. When the second limiting member 52 is arranged in a ring shape, the contact electrode 32 is surrounded by the second limiting member 52. Therefore, the second limiting member 52 can form a buffering effect on the contact electrode 32 to a certain extent to prevent the contact electrode 32 from being damaged by an external mechanism. By arranging the second limiting member 52 in a ring shape and cooperating with the first limiting member 51, a ring-shaped contact can be formed between the first limiting member 51 and the second limiting member 52 along the ring shape of the second limiting member 52, thereby improving the uniformity of the preset gap and preventing the occurrence of deflection angles.

[0046] In some alternative embodiments, in order to improve the uniformity of the preset gap, the number of the first limiting members 51 can be greater than or equal to 2, and the first limiting members 51 are arranged at intervals along the ring shape of the second limiting member 52. In the embodiments of the present application, the number of the first limiting members 51 is generally configured to be 2-3, which can reduce the structural complexity while ensuring the improvement of the uniformity of the preset gap.

[0047] In some alternative embodiments, since among the first limiting member 51 and the second limiting member 52, the material hardness of the first limiting member 51 is greater than that of the second limiting member 52, the dimension of the first limiting member 51 in the height direction can be set to be less than the minimum working dimension of the elastic electrode 23 in the height direction, and the maximum combined dimension of the first limiting member 51 and the second limiting member 52 in the height direction due to mutual abutment is greater than the minimum working dimension of the elastic electrode 23 in the height direction. The minimum working dimension refers to the dimension of the elastic electrode 23 after being extremely compressed in the height direction, and this dimension is the minimum dimension of the elastic electrode 23; the dimension of the first limiting member 51 is less than the minimum working dimension of the elastic electrode 23, and at the same time, the maximum combined dimension after the first limiting member 51 and the second limiting member 52 abut against each other is greater than the minimum working dimension of the elastic electrode 23, which can enable the first limiting member 51 and the second limiting member 52 to abut according to the deformation of the elastic electrode 23, and at the same time, it does not affect the deformable range of the elastic electrode 23. Among them, the maximum combined dimension of the first limiting member 51 and the second limiting member 52 in the height direction due to mutual abutment refers to the sum of the maximum dimensions of the first limiting member 51 and the second limiting member 52 in the height direction after they abut against each other, specifically, it is the sum of the dimensions corresponding to the first limiting member 51 and the second limiting member 52 without deformation due to different material hardnesses.

[0048] In some alternative embodiments, in addition to the split setting, the limiting component 5 may further include an integral limiting member. The integral limiting member is fixedly arranged on the atomization component 2 and extends towards the battery component 3 in the height direction; or, the integral limiting member is fixedly arranged on the battery component 3 and extends towards the atomization component 2 in the height direction. That is to say, the limiting component 5 can be arranged on one side. It can be arranged on the side of the atomization component 2 and abut against the battery body 31 to form a preset gap; it can also be arranged on the side of the battery component 3 and abut against the circuit board 22 to form a preset gap.

[0049] In some alternative embodiments, please refer to Figure 3, in order to implement the anti-fooling design during the installation of the circuit board 22, one or more alignment holes 24 may be provided on the circuit board 22, and the alignment holes 24 penetrate the circuit board 22 in the height direction; the atomization assembly 2 further has an inner housing 25, and the limiting assembly 5 includes a first limiting member 51. The first limiting member 51 is disposed at the end of the inner housing 25 close to the battery assembly 3 in the height direction, and the first limiting member 51 is disposed through the circuit board 22 through the alignment hole 24. Among them, one or more alignment holes 24 are provided on the circuit board 22, and one or more first limiting members 51 are correspondingly provided on the atomization assembly 2. During assembly, it is necessary to pass the first limiting member 51 through each alignment hole 24 on the circuit board 22. If the circuit board 22 is not assembled in place, if the front and back are reversed or the rotation angle is incorrect during assembly, etc., the first limiting member 51 cannot pass through the circuit board 22 normally, resulting in the inability to assemble the circuit board 22, thereby achieving the physical anti-fooling effect. The first limiting member 51 in the embodiment of the present application may cooperate with a second limiting member 52 provided on the battery assembly 3 to form a limiting assembly 5 to form a preset gap between the atomization assembly 2 and the battery assembly 3, or the first limiting member 51 may be used as an integral limiting member alone to directly form a preset gap between the atomization assembly 2 and the battery assembly 3. The first limiting member 51 is disposed through the circuit board 22, and then the first limiting member 51 may be in contact with the second limiting member 52 to form a preset gap between the atomization assembly 2 and the battery assembly 3, or the first limiting member 51 may be in contact with the battery assembly 3 alone to form a preset gap between the atomization assembly 2 and the battery assembly 3.

[0050] The inner housing 25 of the atomization assembly 2 can be used to form a storage chamber, which can be used as a storage space for the various components of the atomization assembly 2, such as the storage space for the pneumatic switch, the storage space for the atomization core, etc.; the specific function of the inner housing 25 can be determined according to the structural layout design of the atomization assembly 2, and it is not specifically limited in the embodiment of the present application.

[0051] In some alternative embodiments, please continue to refer to Figure 4, the contact electrode 32 may specifically include a solder pad or the like that can form a surface contact conductive mechanism; in order to improve the convenience of assembling the battery assembly 3, the contact electrode 32 may specifically include a first conductive region 43 and a second conductive region 44 that are insulated from each other, and the second conductive region 44 is disposed around the first conductive region 43; the number of elastic electrodes 23 is set to two, one of the two elastic electrodes 23 is a first electrode post 45 and the other is a second electrode post 46, and the first electrode post 45 forms a contact electrical connection with the first conductive region 43, and the second electrode post 46 forms a contact electrical connection with the second conductive region 44. The contact electrode 32 in the embodiment of the present application includes a second conductive region 44 arranged in a ring shape and a first conductive region 43 arranged within the second conductive region 44. Therefore, the battery assembly 3 can be connected to the atomization assembly 2 at any rotation angle along the height direction, and the electrical connection between the atomization assembly 2 and the battery assembly 3 can be realized without specifying an angle, thereby greatly improving the convenience of assembly. Among them, the elastic electrode 23 includes a first electrode post 45 and a second electrode post 46, which respectively correspond to the first conductive region 43 and the second conductive region 44, and the second electrode post 46 is eccentrically arranged relative to the center line and is in contact connection with the second conductive region 44; and according to whether the setting position of the first electrode post 45 is eccentrically arranged relative to the center line, the first conductive region 43 can be correspondingly arranged as a circular shape or a circular ring shape.

[0052] In some alternative embodiments, the elastic electrode 23 and the contact electrode 32 may also be arranged in reverse, that is, the elastic electrode 23 is arranged on the battery assembly 3 and the contact electrode 32 is arranged on the atomization assembly 2. The elastic electrode 23 extends in the height direction, and the elastic deformation direction of the elastic electrode 23 is also the same as the height direction.

[0053] In some alternative embodiments, please refer to Figure 5 and 6 As shown, the atomization device 1 may further include a housing assembly 7, and an accommodation cavity 71 is formed in the housing assembly 7; the circuit board 22 is disposed in the accommodation cavity 71, and the circuit board 22 divides the accommodation cavity 71 into a first accommodation space 72 and a second accommodation space 73 in the height direction; the atomization core 21 is located in the first accommodation space 72, and the battery assembly 3 is located in the second accommodation space 73.

[0054] In some alternative embodiments, please refer to Figure 7 and Figure 8, for the convenience of assembling the battery assembly 3, the housing assembly 7 may specifically include a main body portion 76 and an end cover portion 77 that are detachably connected. The end cover portion 77 is disposed at an end of the main body portion 76 away from the atomization assembly 2 in the height direction. An installation hole 761 penetrating the main body portion 76 is provided at the end of the main body portion 76 away from the atomization assembly 2 in the height direction. The size of the installation hole 761 matches that of the end cover portion 77. The end cover portion 77 is detachably connected to the main body portion 76 through the installation hole 761. The installation hole 761 is used for the battery assembly 3 to be inserted into the second accommodation space 73, and the end cover portion 77 is used to close the installation hole 761. Among them, in order to achieve the detachable connection between the main body portion 76 and the end cover portion 77, the end cover portion 77 has a protruding portion 771 extending in a direction perpendicular to the height direction. A clamping groove 762 matching the protruding portion 771 is provided at the edge of the installation hole 761, and the clamping groove 762 communicates with a limiting groove 763 provided on the inner side wall of the installation hole 761 and extending circumferentially; the end cover portion 77 is inserted into the installation hole 761 when the protruding portion 771 is aligned with the clamping groove 762, and rotates along the extending direction of the limiting groove 763 so that the protruding portion 771 is placed in the limiting groove 763. By providing the installation hole 761 at the end of the housing assembly 7 away from the atomization assembly 2 in the height direction, an opening for the battery assembly 3 to be inserted is provided, that is, the battery assembly 3 can be assembled into the second accommodation space from the installation hole 761; and the end cover is detachably connected to the installation hole 761, and the size of the end cover matches that of the installation hole 761.

The protruding portion 771 can be placed in the clamping groove 762 to realize the connection between the end cover and the installation hole 761; after the end cover is placed into the installation hole 761, the end cover can be rotated to make the protruding portion 771 enter the limiting groove 763 along the clamping groove 762, so that the limiting groove 763 limits the end cover to prevent the end cover from falling off, thereby realizing the assembly and fixation between the end cover and the installation hole 761.

[0055] In some alternative embodiments, please refer to Figure 1 , Figure 7 and Figure 8As shown, in order to implement the intake structure required for the atomization core 21 to heat the aerosol matrix to generate aerosol, there is an intake gap 74 between the battery body 31 and the housing assembly 7; an air inlet 75 is provided on the housing assembly 7, and the air inlet is arranged in parallel with the mounting hole 761. The air inlet 75 passes through the intake gap 74 and communicates with the atomization assembly 2. An intake gap 74 is formed between the battery body 31 and the housing assembly 7. Through the intake gap 74, outside air can enter the inside of the atomization device 1, so that when the atomization core 21 heats the aerosol matrix, it can be mixed with air to generate aerosol and be discharged. An air inlet 75 is provided on the housing assembly 7, and the air inlet 75 communicates with the intake gap 74 and then communicates with the atomization assembly 2.

[0056] Since the atomization assembly 2 includes a circuit board 22 and an atomization core 21, through holes can be provided on the circuit board 22 to allow the intake gap 74 to pass through the through holes and communicate with the atomization core 21. Alternatively, an assembly gap can be formed between the circuit board 22 and the housing assembly 7 to allow the intake gap 74 to pass through the assembly gap and communicate with the atomization core 21.

[0057] In the embodiment of the present application, an atomization device 1 is provided. Since the elastic electrode 23 and the contact electrode 32 are electrically connected by contact and there is no need to be connected by welding, it is convenient to realize automatic assembly and improve the convenience of disassembly and assembly; and the limiting assembly makes a preset gap formed between the atomization assembly 2 and the battery assembly 3, avoiding rigid contact of the elastic electrode 23 and damaging the circuit board 22 and the elastic electrode 23, and enhancing the reliability of the electrical connection.

[0058] The embodiment of the present application also provides an aerosol generating device, which includes a liquid replenishing device 8 and the atomization device 1 in the embodiment of the present application; the liquid replenishing device 8 communicates with the atomization assembly 2 and is used to replenish the aerosol matrix.

[0059] The liquid replenishing device 8 is used to replenish the aerosol matrix for the atomization assembly 2; that is to say, the liquid replenishing device 8 can store the aerosol matrix and then replenish the aerosol matrix into the liquid storage space in the atomization assembly 2. To achieve this purpose, the accommodating space of the liquid replenishing device 8 and the liquid storage space can communicate with each other, so as to realize the conduction of the aerosol matrix from the liquid storage device to the liquid storage space.

[0060] In order to facilitate the liquid replenishing device 8 to replenish the aerosol matrix, the opening of the liquid replenishing device 8 can be arranged at the bottom, so as to facilitate the aerosol matrix to be discharged from the opening. In addition, a liquid guiding mechanism 9 can be provided between the liquid replenishing device 8 and the atomization assembly 2. On the one hand, it can be used to guide the aerosol matrix to flow from the liquid replenishing device 8 into the atomization assembly 2, and on the other hand, it can limit the flow of the aerosol matrix flowing in from the liquid replenishing device 8 to prevent the inflow amount per unit time from being too large.

[0061] The above uses specific examples to elaborate on the present utility model, which is only used to help understand the present utility model and is not intended to limit the present utility model. For those skilled in the technical field to which the present utility model pertains, based on the idea of the present utility model, several simple deductions, deformations or substitutions can also be made.
