[0031] It should be noted that, in the absence of conflict, the technical features in the embodiments of the present invention can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the embodiments of the present invention and should not be regarded as an improper limitation on the embodiments of the present invention.

[0033] The present invention provides an aerosol generating device for generating aerosol for a user to inhale. Figures 1 to 8 The aerosol generating device includes a power supply assembly 10 and an atomizer 30 .

[0034] The power supply assembly 10 is provided with a battery 12, which serves as a power source for the aerosol generating device and is used to supply electrical energy to other electrical components in the aerosol generating device, such as a heating device, a pneumatic switch, a display light, etc., to maintain the normal operation of the aerosol generating device.

[0035] The atomizer 30 is provided with an atomizing core, a heating device and an aerosol generating substrate. After power is supplied to the heating device, the heating device heats the atomizing core. The aerosol generating substrate absorbed in the atomizing core is heated until it is atomized to form an aerosol. The aerosol is discharged from the atomizer 30 for inhalation by the user.

[0036] The power supply assembly 10 and the atomizer 30 are arranged opposite to each other along a first direction.

[0037] One of the end faces of the atomizer 30 facing the power supply assembly 10 and the end face of the power supply assembly 10 facing the atomizer 30 is provided with a guide slope 50, and the other is provided with a guide protrusion 40, and both the end faces of the atomizer 30 facing the power supply assembly 10 and the end face of the power supply assembly 10 facing the atomizer 30 are provided with electrodes 60.

[0038] The end surface of the atomizer 30 facing the power supply assembly 10 may be provided with a guide bevel 50, and the end surface of the power supply assembly 10 facing the atomizer 30 may be provided with a guide protrusion 40; or the end surface of the atomizer 30 facing the power supply assembly 10 may be provided with a guide protrusion 40, and the end surface of the power supply assembly 10 facing the atomizer 30 may be provided with a guide bevel 50.

[0039] When the electrode 60 provided on the end face of the atomizer 30 facing the power supply assembly 10 and the electrode 60 provided on the end face of the power supply assembly 10 facing the atomizer 30 are in contact, the connection between the atomizer 30 and the power supply assembly 10 is achieved so that the power supply assembly 10 can provide electrical energy to the atomizer 30.

[0040] The guide protrusion 40 extends along the first direction. That is, in the embodiment where the end surface of the atomizer 30 facing the power assembly 10 is provided with the guide protrusion 40, the guide protrusion 40 protrudes toward the power assembly 10; in the embodiment where the end surface of the power assembly 10 facing the atomizer 30 is provided with the guide protrusion 40, the guide protrusion 40 protrudes toward the atomizer 30.

[0041] The guide slope 50 faces the guide protrusion 40 and is inclined relative to the first direction. That is, the extension direction of the guide slope 50 is neither parallel to the in-and-out direction of the atomizer 30 nor perpendicular to the in-and-out direction of the atomizer 30, but forms a certain angle with the first direction, so that one end of the guide slope 50 along its extension direction is closer to the guide protrusion 40 than the other end.

[0042] The guide protrusion 40 and the guide slope 50 can abut against each other along the first direction and slide relative to each other as the atomizer 30 and the power supply assembly 10 approach each other along the first direction, so as to guide the atomizer 30 to move relative to the power supply assembly 10 to a position where the electrodes 60 of the two are in electrical conduction.

[0043] Through the contact between the guide bevel 50 and the guide protrusion 40, the guide bevel 50 can guide the guide protrusion 40, and by guiding the relative movement path between the guide protrusion 40 and the guide bevel 50, the atomizer 30 is guided to move relative to the power supply assembly 10 according to a pre-set movement path until it reaches a position where the electrodes 60 of the two can achieve electrical conduction.

[0044] Specifically, as the power assembly 10 and the atomizer 30 approach each other, the guide protrusion 40 abuts against the guide slope 50, and then the interaction force generated between the guide protrusion 40 and the guide slope 50 can be divided into a component force perpendicular to the surface of the guide slope 50 and a component force perpendicular to the first direction, wherein the component force perpendicular to the first direction can drive the atomizer 30 and the power assembly 10 to generate a relative movement perpendicular to the first direction, so that the electrodes 60 of the atomizer 30 and the power assembly 10 are relatively moved. In this way, the guide slope 50 continues to abut against the guide protrusion 40 and guides it to move relative to each other along the extension direction of the guide slope 50, so that the atomizer 30 and the power assembly 10 can achieve the purpose of relative movement according to the pre-set movement path, so that the electrodes 60 of the atomizer 30 and the power assembly 10 are close to each other with the guiding effect of the guide slope 50, until the electrodes 60 of the two are in contact to achieve electrical conduction, thereby achieving the purpose of electrical connection between the atomizer 30 and the power assembly 10.

[0045] The aerosol generating device in the embodiment of the utility model can facilitate the electrode 60 of the atomizer 30 and the electrode 60 of the power assembly 10 to approach and contact each other through the cooperation between the guide protrusion 40 and the guide slope 50, thereby increasing the probability of electrical conduction between the electrode 60 of the atomizer 30 and the electrode 60 of the power assembly 10. In this way, in the process of replacing the atomizer 30, the user does not need to observe the relative position between the electrode 60 of the atomizer 30 and the electrode 60 of the power assembly 10. The user only needs to control the relative movement of the power assembly 10 and the atomizer 30 along the first direction to improve the success rate of inserting the atomizer 30 and realizing electrical connection with the power assembly 10, thereby simplifying the operation steps, reducing the difficulty of operation, and improving the user's experience.

[0046] In some embodiments, see Figure 6 One of the power supply assembly 10 and the atomizer 30 is provided with a mounting cavity 20a, and the mounting cavity 20a is open toward the other along a first direction so that the other can enter and exit the mounting cavity 20a, and one of the guide protrusion 40 and the guide slope 50 is provided on the inner wall of the mounting cavity 20a away from its open position, and the electrode 60 provided with the mounting cavity 20a is provided on the inner wall of the mounting cavity 20a away from its open position.

[0047] In this way, the inner wall of the installation cavity 20 a plays a role in shielding and protecting the guide protrusion 40 , the guide slope 50 and the electrode 60 .

[0048] It is understandable that when the atomizer 30 and the power supply assembly 10 without the installation cavity 20a enter and exit the installation cavity 20a, the guide protrusion 40 and the guide slope 50 approach or move away from each other along the entry and exit direction.

[0049] It can be understood that the straight line where the in-and-out direction is located is parallel to the straight line where the first direction is located, and both are in the same direction.

[0050] The entry direction refers to the direction in which one of the atomizer 30 and the power supply assembly 10 that is not provided with the installation cavity 20a is inserted into the installation cavity 20a, and one of the two directions of the straight line direction where the entry and exit directions are located forms the entry direction.

[0051] In some embodiments where the power supply assembly 10 is provided with a mounting cavity 20a, see Figure 6 One side of the installation cavity 20a is opened to form an insertion port 20b, and the atomizer 30 enters and exits the installation cavity through the insertion port 20b.

[0052] It can be understood that when the atomizer 30 is inserted into the plug-in port 20b, on a projection plane perpendicular to the entry and exit direction of the atomizer 30, when the projection of the guide protrusion 40 at least partially overlaps with the projection of the guide slope 50, the guide protrusion 40 can abut against the guide slope 50 along the entry direction of the atomizer 30.

[0053] The specific number of the guide protrusion 40 and the guide slope 50 is not limited, and can be one or more. The number of the guide protrusion 40 and the number of the guide slope 50 can be the same or different.

[0054] The electrode 60 includes a first electrode 61 and a second electrode 62 . The first electrode 61 is disposed on the power supply assembly 10 , and the second electrode 62 is disposed on the atomizer 30 . Both the first electrode 61 and the second electrode 62 extend along the inlet and outlet directions of the atomizer 30 .

[0055] It is understandable that, under the guidance of the abutment between the guide slope 50 and the guide protrusion 40 , the movement of the atomizer 30 relative to the power supply assembly 10 refers to a relative movement that combines translation or rotation in other directions except the entry direction of the atomizer 30 .

[0056] In some embodiments, see Figure 2 and Figure 8The atomizer 30 can rotate relative to the power supply assembly 10 and the rotation axis is parallel to the entry and exit direction of the atomizer 30. The guide slope 50 extends along the rotation direction of the atomizer 30 to guide the atomizer 30 to rotate relative to the power supply assembly 10 when the guide slope 50 and the guide protrusion 40 are in abutment.

[0057] That is to say, the movement of the atomizer 30 relative to the power supply assembly 10 is a composite movement of two movement modes: translation along the first direction and rotation of the atomizer 30 along a rotation axis parallel to the first direction.

[0058] In this way, no translation perpendicular to the entry direction of the atomizer 30 will occur between the atomizer 30 and the power supply assembly 10, which is beneficial to reducing the gap perpendicular to the first direction between the atomizer 30 and the inner wall of the mounting cavity 20a, and further beneficial to reducing the size of the mounting cavity 20a, making the structure of the aerosol generating device more compact, and reducing the probability of foreign matter from the outside entering the aerosol generating device through the gap during use and affecting its normal operation; in addition, it is beneficial to maintain a certain airtightness inside the aerosol generating device compared to the outside world, so that negative pressure can be formed inside the aerosol generating device during the user's inhalation.

[0059] In some embodiments, on the projection plane perpendicular to the first direction, the projection shape of the guide slope 50 is an arc shape, so that the guide slope 50 extends along the rotation direction of the atomizer 30, which is beneficial to reduce the size of the structural parts forming the guide slope 50, making the structure of the aerosol generating device more compact.

[0060] In some embodiments, see Figure 1 When the atomizer 30 is inserted into the mounting cavity 20a and electrically connected to the power supply assembly 10, a portion of the atomizer 30 is located outside the mounting cavity 20a so that the atomizer 30 can be driven to move relative to the power supply assembly 10 through this portion.

[0061] In some embodiments, see Figure 5 The number of the guide slopes 50 is multiple, so as to increase the probability of abutment between the guide protrusion 40 and the guide slope 50 after the atomizer 30 is inserted into the mounting cavity 20a.

[0062] Understandably, see Figure 2 From the perspective of the plug-in port 20b facing the installation cavity 20a, the atomizer 30 rotates relative to the power supply assembly 10, which can be clockwise or counterclockwise.

[0063] In the embodiment where there are multiple guide slopes 50, see Figure 5 A portion of the guide slope 50 extends in the positive direction of the rotation direction of the atomizer 30 , and another portion of the guide slope 50 extends in the reverse direction of the rotation direction of the atomizer 30 .

[0064] The positive rotation direction of the atomizer 30 refers to one of the clockwise and counterclockwise directions of the atomizer 30 relative to the power supply assembly 10 from the perspective of the plug port 20b toward the installation cavity 20a, and the reverse rotation direction of the atomizer 30 is the other direction.

[0065] In this way, after the atomizer 30 is inserted into the installation cavity 20a, no matter it rotates in the forward direction of the rotation direction of the atomizer 30 or rotates in the reverse direction of the rotation direction of the atomizer 30, there is a probability that the atomizer 30 will move relative to the power supply assembly 10 to a position where the electrodes 60 of the two are electrically conductive, thereby improving the convenience of installing the atomizer 30 and helping to enhance the user experience.

[0066] The specific method of forming the guide slope 50 is not limited.

[0067] For example, see Figures 3 to 5 A guide groove 50a is provided on one of the end surface of the atomizer 30 facing the power supply assembly 10 and the end surface of the power supply assembly 10 facing the atomizer 30, and the guide groove 50a is open toward the other to form an opening, and the guide protrusion 40 can enter the guide groove 50a through the opening along the entry direction of the atomizer 30, and the guide groove 50a forms a guide slope 50 on at least one side wall along the rotation direction of the atomizer 30.

[0068] The radial side walls of the guide groove 50a along the rotation axis of the atomizer 30 can constrain the movement of the guide protrusion 40, so as to reduce the probability of the guide protrusion 40 and the guide bevel 50 being out of contact due to the displacement perpendicular to the first direction when the atomizer 30 and the power supply assembly 10 are approaching each other, thereby improving the success rate of the guide protrusion 40 and the guide bevel 50 guiding the electrode 60 to an electrically conductive position.

[0069] At the same time, by embedding the guide protrusion 40 into the guide groove 50a, the size of the aerosol generating device along the first direction is shortened, and the structural compactness of the aerosol generating device is improved.

[0070] In some embodiments, see Figure 5 The side walls of the guide groove 50 a on both sides along the rotation direction of the atomizer 30 form guide inclined surfaces 50 , and the inclination directions of the two guide inclined surfaces 50 are opposite along the rotation direction of the atomizer 30 .

[0071] In this way, under the guidance of the two guide slopes 50, the guide protrusion 40 can rotate in the positive or reverse direction of the rotation direction of the atomizer 30, so that the guide protrusion 40 enters or leaves the guide groove 50a, thereby improving the convenience of installing or removing the atomizer 30 and helping to improve the user experience.

[0072] The specific arrangement of the guide groove 50a is not limited.

[0073] For example, see Figure 4 and Figure 5 The atomizer 30 includes an atomizer seat 31, a cover 32, an atomizer core, and a second electrode 62. The cover 32 is disposed on one end of the atomizer seat 31 along the first direction, so that the two together enclose an oil tank for accommodating an aerosol-generating substrate. A portion of the atomizer core is located in the oil tank to adsorb the aerosol-generating substrate. The second electrode 62 passes through the atomizer seat 31 along the first direction, one end of which is electrically connected to the atomizer core, and the other end of which faces the power supply assembly 10 for being electrically connected to the electrode 60 of the power supply assembly 10. The guide groove 50a is located on the surface of the atomizer seat 31 facing the power supply assembly 10.

[0074] That is, one end of the second electrode 62 for electrically connecting to the power source assembly 10 and the guide groove 50 a are both located on the same side of the atomizer seat 31 along the first direction.

[0075] The specific number of the guide grooves 50a is not limited, and can be one or more.

[0076] The specific arrangement of the guide protrusions 40 is not limited.

[0077] For example, see Figures 6 to 8 The power supply assembly 10 includes a first electrode 61, a mounting bracket 11 and a battery 12. The mounting bracket 11 is provided with a mounting compartment, and the battery 12 is arranged in the mounting compartment. The guide protrusion 40 and the first electrode 61 are both provided at one end of the mounting bracket 11 along the first direction toward the atomizer 30. The first electrode 61 can pass through the mounting bracket 11 to be electrically connected to the battery 12.

[0078] The mounting bracket 11 provides a mounting position for the battery 12 and plays a certain protective role.

[0079] The specific method of forming the mounting cavity 20a is not limited.

[0080] For example, see Figure 4 The power supply assembly 10 also includes a shell 20, in which a storage space is provided. One side of the storage space along the first direction is open to form a plug-in port 20b. The mounting bracket 11 is located in the storage space. A surface of the mounting bracket 11 facing the plug-in port 20b and an inner wall of the storage space on a side close to the plug-in port 20b are jointly formed to form a mounting cavity 20a.

[0081] The housing 20 can protect the electrical connection position between the atomizer 30 and the power supply assembly 10 to reduce the probability of problems such as short circuit and leakage during the use of the aerosol generating device.

[0082] The nebulizer 30 can enter and exit the installation cavity 20a through the plug-in port 20b, so that the nebulizer 30 that has exhausted the aerosol generating matrix can be unplugged from the plug-in port 20b, and the nebulizer 30 filled with the aerosol generating matrix can be inserted from the plug-in port 20b and connected to the power supply assembly 10 to achieve the reuse of the aerosol generating device.

[0083] In some embodiments, see Figure 5 and Figure 8 On the projection plane perpendicular to the first direction, the projection of the atomizer 30 and the projection of the shell 20 are both circular, so that the atomizer 30 can rotate relative to the shell 20, and it is helpful to reduce the gap between the atomizer 30 and the inner wall of the installation cavity 20a. At the same time, the shell 20 can guide the atomizer 30, reduce the translation of the atomizer 30 relative to the power supply assembly 10 perpendicular to the entry direction of the atomizer 30, and reduce the probability of the guide protrusion 40 and the guide slope 50 being separated.

[0084] In some embodiments, see Figure 7 The guide protrusion 40 protrudes from the first electrode 61 along the first direction, which is conducive to the guide protrusion 40 abutting against the guide slope 50 before the first electrode 61 abuts against the atomizer 30 along the entry direction of the atomizer 30, thereby guiding the first electrode 61 to move toward the second electrode 62 until the two are in contact and electrically conductive.

[0085] It is understandable that, when a user uses the aerosol generating device, it is necessary to suppress the tendency of the atomizer 30 to separate from the power supply assembly 10 along the first direction.

[0086] In some embodiments, see Figure 5 , Figure 6 and Figure 8 One of the end surface of the atomizer 30 facing the power supply assembly 10 and the end surface of the power supply assembly 10 facing the atomizer 30 is provided with a first magnetic component 70, and the other is provided with a second magnetic component 71. A magnetic attraction force along a first direction is generated between the first magnetic component 70 and the second magnetic component 71. When the first magnetic component 70 and the second magnetic component 71 are attached to each other in the first direction, the electrode 60 of the atomizer 30 and the electrode 60 of the power supply assembly 10 are in an electrically conductive state.

[0087] That is, the magnetic polarity of one end of the first magnetic member 70 facing the second magnetic member 71 is opposite to the magnetic polarity of one end of the second magnetic member 71 facing the first magnetic member 70 , so that a magnetic attraction force is generated between the two.

[0088] Under the action of the magnetic force between the first magnetic member 70 and the second magnetic member 71, the atomizer 30 and the power supply assembly 10 can approach each other along the first direction, and at the same time, the guide protrusion 40 abuts against the guide slope 50 and generates relative movement, so that the atomizer 30 moves relative to the power supply assembly 10 to a position where the electrodes 60 of the two are in electrical conduction. At the same time, the first magnetic member 70 and the second magnetic member 71 fit together to limit the relative position between the atomizer 30 and the power supply assembly 10.

[0089] In this way, through the magnetic attraction between the first magnetic attraction component 70 and the second magnetic attraction component 71, on the one hand, it can provide driving force for the atomizer 30 and the power supply assembly 10 to approach each other, so that the user can install the atomizer 30 conveniently; on the other hand, during the normal use of the aerosol generating device, it can suppress the relative movement tendency between the atomizer 30 and the power supply assembly 10, thereby reducing the risk of problems such as poor contact in the electrical connection between the two.

[0090] It is understandable that the first magnetic member 70 and the second magnetic member 71 need to be within a certain distance range to generate a driving force sufficient to drive the atomizer 30 and the power supply assembly 10 to move closer to each other.

[0091] In some embodiments, the guide slope 50 and the first magnetic component 70 are located in the same one of the atomizer 30 and the power supply assembly 10, the end of the guide slope 50 close to the guide protrusion 40 is the first end, and the end of the guide slope 50 away from the guide protrusion 40 is the second end, and on the projection plane perpendicular to the first direction, the distance between the projection of the second end and the projection of the first magnetic component 70 is smaller than the distance between the projection of the first end and the projection of the first magnetic component 70.

[0092] That is to say, the guide protrusion 40 and the second magnetic member 71 are located on the other of the atomizer 30 and the power supply assembly 10. When the atomizer 30 enters the installation cavity 20a, as the guide protrusion 40 moves on the guide slope 50, the atomizer 30 can move as a whole toward the first magnetic member 70. The distance between the first magnetic member 70 and the second magnetic member 71 gradually decreases, and as the distance between the two decreases, the magnitude of the magnetic attraction between the two gradually increases, thereby further driving the first magnetic member 70 and the second magnetic member 71 to approach each other, causing the two to get closer and closer until the two are fitted, and the power supply assembly 10 and the atomizer 30 are electrically connected.

[0093] In this way, through the guiding effect of the guiding slope 50 on the guiding protrusion 40, the first magnetic component 70 is more likely to move relative to the second magnetic component 71, thereby increasing the magnetic attraction between the two, so that the two drive the atomizer 30 and the power supply assembly 10 to be close and fixed by the magnetic attraction.

[0094] The specific arrangement of the first magnetic member 70 and the second magnetic member 71 is not limited.

[0095] For example, in an embodiment where the atomizer 30 can rotate relative to the power supply assembly 10 and the rotation axis is parallel to the first direction, and the guide slope 50 extends along the rotation direction of the atomizer 30, refer to Figure 5 and Figure 8 The number of the first magnetic members 70 and the number of the second magnetic members 71 are both plural, and are respectively arranged at intervals along the rotation direction of the atomizer 30 .

[0096] In this way, during the rotation of the atomizer 30 relative to the power supply assembly 10, the distance between the first magnetic member 70 and the second magnetic member 71 can change, which is beneficial for adjusting the relative position relationship between the guide protrusion 40 and the guide bevel 50, so that as the guide protrusion 40 moves on the guide bevel 50, the first magnetic member 70 rotates relative to the second magnetic member 71 to the position where the distance between the two is closest, so as to generate a larger magnetic attraction force at this position to drive the atomizer 30 and the power supply assembly 10 to approach each other.

[0097] The number of the first magnetic elements 70 and the number of the second magnetic elements 71 may be the same or different.

[0098] In some embodiments, in a projection perpendicular to the first direction, at least a portion of the projection of the first magnetic member 70 is located within the projection range of the second magnetic member 71 relative to the rotation trajectory of the first magnetic member 70. In this way, during the rotation of the first magnetic member 70 relative to the second magnetic member 71, the first magnetic member 70 and the second magnetic member 71 can be arranged relative to each other along the first direction, so as to generate a larger magnetic attraction force at this position to drive the atomizer 30 and the power supply assembly 10 to approach each other.

[0099] It can be understood that in an embodiment having multiple first magnetic components 70 and multiple second magnetic components 71, on a projection plane perpendicular to the first direction, when the distance between the projection of the first magnetic component 70 and the projections of two adjacent second magnetic components 71 is equal, the magnitude of the magnetic attraction between the first magnetic component 70 and the second magnetic component 71 is at a minimum state. In this state, there is a probability that the magnitude of the magnetic attraction between the first magnetic component 70 and the second magnetic component 71 cannot overcome the resistance such as friction between the atomizer 30 and the power supply assembly 10, and cannot drive the atomizer 30 and the power supply assembly 10 to move relative to each other.

[0100] In some embodiments, on a projection plane perpendicular to the first direction, when the distance between the projection of the first magnetic member 70 and the projections of two adjacent second magnetic members 71 is equal, the projection of the guide protrusion 40 is within the projection range of the guide slope 50 .

[0101] In this way, even when the distance between the projection of the first magnetic component 70 and the projection of the two adjacent second magnetic components 71 is equal on the projection plane perpendicular to the first direction, the guide protrusion 40 can abut against the guide slope 50, thereby allowing the atomizer 30 to rotate relative to the power supply assembly 10, so that the first magnetic component 70 moves toward one of the two adjacent second magnetic components 71, thereby increasing the magnetic attraction between the first magnetic component 70 and the second magnetic component 71, which is beneficial to driving the atomizer 30 and the power supply assembly 10 to move relative to each other until the first magnetic component 70 and the second magnetic component 71 are adsorbed and fit together.

[0102] In some embodiments, see Figure 7 and Figure 8 The guide protrusion 40 protrudes from the second magnetic member 71 along the first direction, which is conducive to the guide protrusion 40 abutting against the guide inclined surface 50 before the first magnetic member 70 is adsorbed and fitted with the second magnetic member 71 along the entry direction of the atomizer 30, thereby guiding the first magnetic member 70 and the second magnetic member 71 to move relative to each other until the two are adsorbed and fitted.

[0103] In the embodiment where the guide protrusion 40 protrudes from the second magnetic attraction member 71 along the first direction, see Figure 8 The guide protrusion 40 is located between two adjacent second magnetic members 71 along the rotation direction of the atomizer 30 , and the distance between the guide protrusion 40 and one of them is greater than the distance between the guide protrusion 40 and the other.

[0104] In this way, during the process of inserting the atomizer 30 into the installation cavity 20a, even if the first magnetic component 70 abuts against the guide protrusion 40 along the entry direction of the atomizer 30, since the guide protrusion 40 is closer to one of the two adjacent second magnetic components 71, the situation where the first magnetic component 70 abutting against the guide protrusion 40 and the two adjacent second magnetic components 71 are equal is avoided, so that the magnetic attraction force between the first magnetic component 70 and one of the second magnetic components 71 is greater, which is beneficial for the atomizer 30 to be in any position relative to the power supply assembly 10 after being inserted into the installation cavity 20a, so that the magnetic attraction force between the first magnetic component 70 and the second magnetic component 71 can drive the atomizer 30 and the power supply assembly 10 to rotate relative to each other until they are in contact, so as to electrically connect the atomizer 30 and the power supply assembly 10.

[0105] It is understandable that the number of the guiding inclined surfaces 50 disposed between two adjacent first magnetic elements 70 is not limited, and may be one or more.

[0106] In some embodiments, see Figure 5 Two guiding inclined surfaces 50 are disposed between two adjacent first magnetic members 70 , and the inclination directions of the two guiding inclined surfaces 50 are opposite to the rotation direction of the atomizer 30 .

[0107] In this way, the second magnetic component 71 can rotate in the forward or reverse direction of the rotation direction of the atomizer 30 under the guidance of the guide protrusion 40 and the guide slope 50 and approach one of the two adjacent first magnetic components 70, so that after the atomizer 30 is inserted into the installation cavity 20a, the magnetic attraction force between the first magnetic component 70 and the second magnetic component 71 can drive the atomizer 30 and the power supply assembly 10 to rotate relative to each other until they are in contact with each other in any position relative to the power supply assembly 10.

[0108] It can be understood that, on the projection plane perpendicular to the first direction, the angle between the geometric center of the projection of the first magnetic component 70 and the geometric center of the projection of the second magnetic component 71 along the rotation direction of the atomizer 30 does not exceed the preset adsorption angle, so that the magnetic attraction force between the first magnetic component 70 and the second magnetic component 71 can drive the atomizer 30 and the power supply assembly 10 to produce relative rotation.

[0109] In some embodiments where the projection of the guide slope 50 perpendicular to the first direction is an arc shape, on the projection plane perpendicular to the first direction, the angle between the geometric centers of the projections of two adjacent first magnetic components 70 is a first angle, the sum of the arc angles of all guide slopes 50 between two adjacent first magnetic components 70 is the first angle, and the sum of the first angle and the preset adsorption angle is not less than half of the first angle.

[0110] For example, the preset adsorption angle is 30°, and the number of the first magnetic members 70 is two, that is, the first angle is 180°, and the first angle is not less than 60°.

[0111] In this way, after the atomizer 30 is inserted into the installation cavity 20a, the magnetic attraction between the first magnetic member 70 and the second magnetic member 71 can drive the atomizer 30 and the power supply assembly 10 to rotate relative to each other at any position relative to the power supply assembly 10.

[0112] It should be noted that the specific angle value of the preset adsorption angle is related to factors such as the magnetic attraction force and size of the first magnetic component 70 and the second magnetic component 71, the size of the aerosol generating device, etc. The specific value determination method has been applied in related technologies and will not be repeated here.

[0113] In some embodiments, both the guide protrusion 40 and the guide slope 50 are magnetic, and the magnetic polarity of one end of the guide slope 50 close to the guide protrusion 40 is the same as the magnetic polarity of the guide protrusion 40 .

[0114] In this way, according to the principle that like magnetic poles repel each other, under the action of magnetic repulsion, the guide protrusion 40 is facilitated to move toward the end of the guide slope 50 away from the guide protrusion 40, which is conducive to guiding the formation of an electrical connection between the atomizer 30 and the power supply assembly 10.

[0115] In some embodiments, both the guide protrusion 40 and the guide slope 50 are magnetic, and the magnetic polarity of one end of the guide slope 50 away from the guide protrusion 40 is different from the magnetic polarity of the guide protrusion 40 .

[0116] In this way, according to the principle of attraction between like magnetic poles, under the action of magnetic attraction, the guide protrusion 40 is facilitated to move toward the end of the guide slope 50 away from the guide protrusion 40, which is conducive to guiding the formation of an electrical connection between the atomizer 30 and the power supply assembly 10.

[0117] The shape of one end of the guide protrusion 40 facing the guide slope 50 is conducive to the relative movement between the two.

[0118] Specifically, see Figure 8 The guide protrusion 40 is in the shape of a pyramid, a prism, or a sphere.

[0119] This is conducive to generating a component force perpendicular to the first direction between the guide protrusion 40 and the guide slope 50, so as to guide the relative movement between the two and reduce the probability of damage caused by stress concentration due to abutment between the two.
