Description

Technical Field

[0001] The present application relates to the field of aerosol generating devices, and particularly to a control component of an aerosol generating device and an aerosol generating device. Background Art

[0002] There are two common structural forms of aerosol generating devices. One is an integrated structure, and the other is a split structure. Among them, the aerosol generating device with a split structure usually includes an atomizer and a power supply component, and the two are detachably connected.

[0003] The atomizer is mainly used to accommodate an aerosol matrix and heat the aerosol matrix to generate an aerosol. In addition to supplying power to the atomizer, the power supply component also plays a role in controlling the operation of the atomizer. An airflow sensor is provided inside the power supply component. During the use of the aerosol generating device by the user, the change in the airflow in the induction airway of the atomizer can trigger the airflow sensor, thereby controlling the operation of the atomizer.

[0004] In some cases, users hope to update their aerosol generating devices, but the cost of updating the devices is usually relatively high. Summary of the Invention

[0021] The exposed portion of one of the two second electrical connectors is located at the geometric center of the outer surface of the second housing wall.

[0022] In some examples, the control assembly further includes a second housing and a display panel. The first housing covers the second housing, and there is a gap between the first housing and the second housing;

[0023] The display panel is located in the gap between the first housing and the second housing.

[0024] In some examples, the control assembly further includes a first magnetic attraction member and a second magnetic attraction member. Both the first magnetic attraction member and the second magnetic attraction member are located in the first housing.

When the control component is connected to the atomizer, the airflow sensor connected to the circuit board can also be opposite to the induction air passage of the atomizer through the detection hole in the first housing wall, so that the airflow change in the induction air passage can normally trigger the airflow sensor. The control component is independent of the power source and the atomizer, so that the atomizer, the control component, and the power source can be replaced separately, which is beneficial to reducing the cost of updating the aerosol generating device.

[0060] Figure 1 It is a schematic structural diagram of an aerosol generating device provided by an embodiment of the present application. As Figure 1 shown, the aerosol generating device includes a power supply assembly 100 and an atomizer 200. The power supply assembly 100 is used to supply power to the atomizer 200 and control the operation of the atomizer 200.

[0061] The power supply assembly 100 is internally provided with structures such as a power source and a circuit board. Electronic devices, such as an airflow sensor, are provided on the surface of the circuit board. The power source can be used to provide electrical energy, and the circuit board and the electronic devices on the surface of the circuit board can be used to control the operation of the atomizer 200. The atomizer 200 is used to store the aerosol matrix and heat the aerosol matrix to form an aerosol.

[0062] In some cases, users may wish to update their aerosol generating devices. For example, they may want to experience different aerosol matrices, or there may be an abnormality in the atomization function of the atomizer 200, in which case the atomizer 200 can be replaced. Another example is that the capacity of the power supply can no longer meet the user's requirements, and the power supply component 100 can be replaced. Different power supply components 100 may have different functions. For example, the same atomizer 200 may operate in different modes under the control of different power supply components 100, such as at least one of the heating power, heating temperature, and heating time being different, thereby producing different atomization effects. When users want to experience different functions, they can replace the power supply component 100.

[0063] Generally, users may only want to replace the battery with a new one or experience new functions, but they have to replace the entire power supply component 100, resulting in a high cost for users to update the aerosol generating device and also causing waste.

[0064] Figure 2 is a schematic structural diagram of an aerosol generating device provided by an embodiment of the present application, as Figure 2 shown, the aerosol generating device includes an atomizer 200, a power supply 400, and a control component 300. The control component 300 is detachably connected to the atomizer 200 and the power supply 400 respectively.

[0065] The control component 300 is independent of the power supply 400 and the atomizer 200, enabling the atomizer 200, the control component 300, and the power supply 400 to be replaced separately, which helps to reduce the cost of updating the aerosol generating device.

[0066] Figure 3 is a schematic structural diagram of a control component of an aerosol generating device provided by an embodiment of the present application, as Figure 3 shown, the control component includes a first housing 10, a plurality of first electrical connectors 13, a plurality of second electrical connectors 14, a circuit board 15, and an airflow sensor 16.

[0067] The first housing 10 has a first housing wall 101, and the first housing wall 101 has a detection hole 101a, and the detection hole 101a is used to communicate with the induction air duct 200a of the atomizer 200.

[0068] The circuit board 15 is located in the first housing 10, the airflow sensor 16 is connected to the circuit board 15, and the airflow sensor 16 is opposite to the detection hole 101a.

[0069] A plurality of first electrical connectors 13 are all connected to the circuit board 15, and at least a part of the first electrical connectors 13 is exposed outside the first housing wall 101, and the exposed part is used to form an electrical connection with the atomizer 200.

[0070] A plurality of second electrical connectors 14 are all connected to the circuit board 15. Figure 4 It is a schematic structural diagram of a control component of an aerosol generating device provided by an embodiment of the present application. As Figure 4 shown, the first housing 10 further has a second housing wall 102. The second housing wall 102 can be opposite to the first housing wall 101. At least part of the second electrical connector 14 is exposed outside the second housing wall 102, and the exposed part is used to form an electrical connection with the power supply 400.

[0071] In the embodiments of the present application, being exposed, being exposed outside, or being exposed can mean being visible or touchable from the outside, can be protruding relative to the outer surface, can also be flush with the outer surface, and can also be concave relative to the outer surface; the exposed part means the part that can be seen or touched from the outside. For example, at least part of the first electrical connector 13 being exposed outside the first housing wall 101 can mean that at least part of the first electrical connector 13 can be observed or touched from the outside of the first housing wall 101.

[0072] In the aerosol generating device, the atomizer 200 is arranged opposite to the first housing wall 101, and the atomizer 200 forms an electrical connection with the first electrical connector 13; the power supply 400 is arranged opposite to the second housing wall 102, and the power supply 400 forms an electrical connection with the second electrical connector 14.

[0073] By providing an independent control component 300, the control component 300 includes a first housing 10, a plurality of first electrical connectors 13, a plurality of second electrical connectors 14, a circuit board 15, and an airflow sensor 16. The first electrical connector 13 and the second electrical connector 14 are respectively connected to the circuit board 15, and the first electrical connector 13 and the second electrical connector 14 respectively protrude from the opposite first housing wall 101 and second housing wall 102 of the first housing 10, so that when using the aerosol generating device, the first electrical connector 13 can be used to form an electrical connection with the atomizer 200, and the second electrical connector 14 can be used to form an electrical connection with the power supply. When the control component is connected to the atomizer 200, the airflow sensor 16 connected to the circuit board 15 can also be opposite to the induction air passage 200a of the atomizer 200 through the detection hole 101a of the first housing wall 101, so that the airflow change in the induction air passage 200a can normally trigger the airflow sensor 16. The control component 300 is independent of the power supply 400 and the atomizer 200, so that the atomizer 200, the control component 300, and the power supply 400 can be replaced separately, which is beneficial to reducing the cost of updating the aerosol generating device.

[0074] In some examples, the first housing 10 can be in a prismatic shape, for example, a quadrangular prism shape, to facilitate the user's holding. The corners of the prism can be rounded. As an example, the first housing 10 can be in a regular quadrangular prism shape, the first housing wall 101 can be the top wall of the regular quadrangular prism, and the second housing wall 102 can be the bottom wall of the regular quadrangular prism.

[0075] Exemplarily, the first housing 10 may include a first outer shell 11 and a first base 12, and the first outer shell 11 and the first base 12 are connected to form a cavity. The first outer shell 11 includes a first shell wall 101, and the first base 12 includes a second shell wall 102.

[0076] Figure 5 It is a schematic structural diagram of a control component of an aerosol generating device provided by an embodiment of the present application. As Figure 5 shown, the outer surface of the first shell wall 101 has a first concave portion 101b, and the detection hole 101a and the exposed part of the first electrical connector 13 are both located in the first concave portion 101b.

[0077] When the control component 300 is connected to the atomizer 200, the first concave portion 101b can be attached to the outer surface of the atomizer 200 for positioning, making it easier to assemble the control component 300 and the atomizer 200. Arranging the detection hole 101a in the first concave portion 101b can also reduce the risk of foreign objects entering the detection hole 101a and avoid blockage of the detection hole 101a. At the same time, it can also reduce the wear near the detection hole 101a and avoid air leakage near the connection between the detection hole 101a and the induction air passage 200a when the control component 300 is connected to the atomizer 200.

[0078] As an example, the detection hole 101a may be located at the geometric center of the first concave portion 101b.

[0079] As Figure 5 shown, the first shell wall 101 further has a gas guiding groove 101c. The gas guiding groove 101c is located on the outer surface of the first shell wall 101 and at the edge of the first concave portion 101b. The gas guiding groove 101c communicates the inside and outside of the first concave portion 101b, that is, one end of the gas guiding groove 101c communicates with the first concave portion 101b, and the other end of the gas guiding groove 101c extends to the circumferential outer edge of the first shell wall 101.

[0080] In addition to inhaling air through the induction air passage 200a, the atomizer 200 also inhales air through the air inlet hole 200b. When the atomizer 200 is connected to the control component 300, the gas guiding groove 101c can ensure smooth air intake of the air inlet hole 200b and avoid the air inlet hole 200b being blocked by the surface of the first shell wall 101.

[0081] As an example, the first shell wall 101 has a plurality of gas guiding grooves 101c, and the plurality of gas guiding grooves 101c are symmetrically distributed around the center of the detection hole 101a.

[0082] The detection hole 101a is located at the geometric center of the first concave portion 101b. That is to say, the air guiding grooves 101c are also symmetrically distributed around the geometric center of the first concave portion 101b. When connecting the atomizer 200 and the control component 300, it is more flexible. Even if the atomizer 200 is rotated 180° for connection, the detection hole 101a can still be aligned with the atomization channel 220a of the atomizer 200, and the air inlet hole 200b can still intake air smoothly through the air guiding grooves 101c.

[0083] As Figure 5 shown, the control component 300 may include two first electrical connectors 13, and the exposed parts of the two first electrical connectors 13 are symmetrically distributed around the geometric center of the outer surface of the first housing wall 101.

[0084] The geometric center of the outer surface of the first housing wall 101 may coincide with the geometric center of the first concave portion 101b. The exposed parts of the two first electrical connectors 13 are symmetrically distributed around the detection hole 101a.

[0085] When the atomizer 200 is connected to the control component 300, in addition to ensuring the smoothness of the gas path, the circuit also needs to be connected. The exposed parts of the first electrical connectors 13 are used to contact the atomizer 200 to achieve electrical connection. The exposed parts of the two first electrical connectors 13 are centrosymmetric, making it more flexible when connecting the atomizer 200 and the control component 300. Even if the atomizer 200 is rotated 180° for connection, the exposed parts of the two first electrical connectors 13 can still normally contact the atomizer 200 to ensure the normal connection of the circuit.

[0086] Referring to Figure 4 shown, the outer surface of the second housing wall 102 has a first convex portion 102a, and the exposed part of the second electrical connector 14 is located on the first convex portion 102a.

[0087] When the control component 300 is connected to the power source 400, the first convex portion 102a can be attached to the outer surface of the power source 400 for positioning, which is convenient for the connection between the control component 300 and the power source 400. Moreover, the first convex portion 102a is a convex structure, and the first concave portion 101b is a concave structure. The structural forms of the two are quite different, making it difficult for the second housing wall 102 to cooperate with the surface of the atomizer 200, and it is difficult for the first housing wall 101 to cooperate with the surface of the power source 400, which can reduce the risk that the user accidentally flips the control component 300, connects the second electrical connector 14 to the atomizer 200, and connects the first electrical connector 13 to the power source 400.

[0088] The distribution pattern of the exposed portions of the plurality of first electrical connectors 13 on the first housing wall 101 may be different from the distribution pattern of the exposed portions of the plurality of second electrical connectors 14 on the second housing wall 102. To facilitate comparison of the distribution pattern of the exposed portions of the plurality of first electrical connectors 13 on the first housing wall 101 and the distribution pattern of the exposed portions of the plurality of second electrical connectors 14 on the second housing wall 102, a first projection plane is defined, and the first projection plane is parallel to the outer surface of the first housing wall 101 or parallel to the outer surface of the second housing wall 102. For example, the first projection plane may be parallel to the first recess 101b.

[0089] In some examples, the orthographic projections of the exposed portions of the plurality of first electrical connectors 13 and the exposed portions of the plurality of second electrical connectors 14 on the first projection plane overlap at most partially.

[0090] The exposed portions of the first electrical connectors 13 are used to contact the atomizer 200 to form an electrical connection, and the exposed portions of the second electrical connectors 14 are used to contact the power source 400 to form an electrical connection. Suppose that the orthographic projections of the exposed portions of the plurality of first electrical connectors 13 and the exposed portions of the plurality of second electrical connectors 14 on the first projection plane completely overlap. Then, when assembling the atomizer 200, the control component 300, and the power source 400, there is a possibility of directly connecting the power source 400 to the atomizer 200 to form an electrical connection between the power source 400 and the atomizer 200, and there is also a risk of incorrectly connecting the circuit and damaging the aerosol generating device. Moreover, there is also a risk of accidentally inverting the control component 300, forming an electrical connection between the second electrical connectors 14 of the control component 300 and the atomizer 200, and forming an electrical connection between the first electrical connectors 13 and the power source 400, thereby damaging the aerosol generating device.

[0091] By adopting the design that the orthographic projections of the exposed portions of the plurality of first electrical connectors 13 and the exposed portions of the plurality of second electrical connectors 14 on the first projection plane overlap at most partially, even if the user accidentally connects the power source 400 and the atomizer 200 that match the control component 300, or inverts the control component 300, the circuit will not be connected, thus avoiding damage to the aerosol generating device.

[0092] In some examples, the orthographic projections of the exposed portions of the plurality of first electrical connectors 13 and the exposed portions of the plurality of second electrical connectors 14 on the first projection plane may also be at most partially rotationally symmetric.

[0093] Assume that the exposed portions of multiple first electrical connectors 13 and the exposed portions of multiple second electrical connectors 14 are rotationally symmetric in the orthographic projection on the first projection plane. Then, when assembling the atomizer 200, the control component 300, and the power source 400, there is also a possibility of directly connecting the power source 400 to the atomizer 200 to form an electrical connection between the power source 400 and the atomizer 200, as well as the possibility of accidentally causing the control component 300 to form an electrical connection between the second electrical connector 14 of the control component 300 and the atomizer 200, and forming an electrical connection between the first electrical connector 13 and the power source 400. By adopting a design in which the exposed portions of multiple first electrical connectors 13 and the exposed portions of multiple second electrical connectors 14 are at most partially rotationally symmetric in the orthographic projection on the first projection plane, the safety during the assembly of the aerosol generating device can also be improved, and the aerosol generating device can be prevented from being damaged due to incorrect circuit connection.

[0094] As an example, the exposed portion of one of the two second electrical connectors 14 is located at the geometric center of the outer surface of the second housing wall 102.

[0095] The geometric center of the outer surface of the second housing wall 102 can coincide with the geometric center of the first convex portion 102a. By arranging the exposed portion of one of the two second electrical connectors 14 at the geometric center of the outer surface of the second housing wall 102 and the exposed portion of the other second electrical connector 14 being eccentrically arranged, when the control component 300 is connected to the power source 400, a specific angle is required to enable the two second electrical connectors 14 to form electrical connections with the power source 400 respectively.

[0096] In this example, the exposed portions of the two first electrical connectors 13 are symmetrically distributed about the geometric center of the outer surface of the first housing wall 101, while for the exposed portions of the two second electrical connectors 14, one is arranged in the center and the other is eccentrically arranged, so that even if the control component 300 is inverted or the power source 400 is directly connected to the atomizer 200, the circuit cannot be switched on, preventing the aerosol generating device from being damaged.

[0097] Referring to FIG. 2, the control component may further include a second housing 17 and a display panel 18. The first housing 10 covers the second housing 17, and there is a gap between the first housing 10 and the second housing 17. The display panel 18 is located in the gap between the first housing 10 and the second housing 17.

[0098] By providing the display panel 18, it is convenient for the user to view some information, such as the power of the aerosol generating device and the amount of the remaining aerosol matrix. By arranging the display panel 18 in the gap between the first housing 10 and the second housing 17, the outer surface of the second housing 17 and the inner surface of the first housing 10 can play a supporting role, making the installation of the display panel 18 more stable.

[0099] As an example, the control component may further include a connector 151. The connector 151 can be connected to the circuit board 15, and the interface of the connector 151 is exposed outside the first housing 10. The connector 151 can be used to connect the control component to other electronic devices, such as a mobile terminal. The connector 151 can also be used to charge the power supply 400, and the control component 300 is used as a charger.

[0100] The display panel 18 can be arranged around the side wall of the second housing 17. For example, the second housing 17 can have 4 side walls, and the display panel 18 can be arranged along 3 side walls of the second housing 17, that is, the display panel 18 is arranged corresponding to 3 side walls of the first housing 10, enabling the user to observe the display screen from outside 3 side walls of the first housing 10. The connector 151 can be exposed outside another side wall of the first housing 10 to avoid the difficulty of arranging the connector 151 and the display panel 18 on the same side of the first housing 10.

[0101] As Figure 3 shown, the control component further includes a first magnetic attracting member 191 and a second magnetic attracting member 192. Both the first magnetic attracting member 191 and the second magnetic attracting member 192 are located in the first housing 10. The first magnetic attracting member 191 is arranged adjacent to the first housing wall 101, and the first magnetic attracting member 191 is used to adsorb the atomizer 200. The second magnetic attracting member 192 is arranged adjacent to the second housing wall 102, and the second magnetic attracting member 192 is used to adsorb the power supply 400.

[0102] The first magnetic attracting member 191 being arranged adjacent to the first housing wall 101 means that the distance from the first magnetic attracting member 191 to the first housing wall 101 is less than the distance from the first magnetic attracting member 191 to the second housing wall 102; the second magnetic attracting member 192 being arranged adjacent to the second housing wall 102 means that the distance from the second magnetic attracting member 192 to the second housing wall 102 is less than the distance from the second magnetic attracting member 192 to the first housing wall 101.

[0103] By arranging the first magnetic attracting member 191 and the second magnetic attracting member 192, it is convenient for the connection between the control component 300, the atomizer 200, and the power supply 400.

[0104] The second housing 17 can be connected to the first base 12. One side of the second housing 17 away from the first base 12 can have a first groove 17a, and the first magnetic attracting member 191 can be located in the first groove 17a.

[0105] One side of the first base 12 close to the second housing 17 can have a second groove 12a, and the second magnetic attracting member 192 can be located in the second groove 12a.

[0106] In some examples, both the first electrical connector 13 and the second electrical connector 14 can be spring pins.

[0107] The spring pin is elastic and can keep the first electrical connector 13 in contact with the atomizer 200 and the second electrical connector 14 in contact with the power source 400 under its own elasticity, reducing the risk of poor contact.

[0108] The spring pin has a simple structure and high stability. In other possible implementations, the first electrical connector 13 and the second electrical connector 14 can also be elastic pieces.

[0109] Figure 6 It is a schematic structural diagram of an atomizer of an aerosol generating device provided by an embodiment of the present application. As Figure 6 shown, the atomizer 200 includes a third housing 20 and a plurality of third electrical connectors 24. At least a part of the third electrical connector 24 is exposed outside the third housing 20, and the exposed part of the third electrical connector 24 is in contact with the first electrical connector 13.

[0110] Figure 7 It is a schematic internal structure diagram of an atomizer provided by an embodiment of the present application. Figure 7 It shows the structure after the atomizer 200 is cut along the Figure 6 dotted line in. As Figure 7 shown, the third housing 20 can include a second outer shell 21 and a second base 22, and the second outer shell 21 and the second base 22 are connected. The induction air passage 200a and the air inlet hole 200b can be located in the second base 22.

[0111] The atomizer 200 can further include a liquid storage component 210, an atomization component 220, and a mouthpiece 230. The liquid storage component 210 and the atomization component 220 can be located inside the third housing 20, and at least a part of the mouthpiece 230 is exposed outside the third housing 20.

[0112] The liquid storage component 210 is used to store the aerosol matrix. The atomization component 220 is located in the liquid storage component 210. The atomization component 220 is used to heat the aerosol matrix, and the atomization component 220 is formed with an atomization channel 220a. The mouthpiece 230 is communicated with one end of the atomization channel 220a.

[0113] The liquid storage component 210 can be located in the third housing 20. The liquid storage component 210 can include a liquid storage chamber housing 211 and a third base 212. The third base 212 is in sealed cooperation with the liquid storage chamber housing 211 to form a liquid storage chamber for accommodating the aerosol matrix.

[0114] In some examples, the liquid storage component 210 can further include a liquid storage member. For example, the liquid storage member can be a liquid storage cotton, and the liquid storage cotton is adsorbed / infiltrated with the aerosol matrix.

[0115] The atomization component 220 is located in the liquid storage housing 211. The atomization component 220 includes a tubular bracket, a liquid guiding member, a heating member, and pins. The liquid guiding member and the heating member are located in the tubular bracket. The pins are electrically connected to the heating member and the third electrical connecting member 24.

[0116] The tubular bracket provides a space inside the liquid storage housing 211 to accommodate the liquid guiding member and the heating member. Structures such as holes and slits can be provided on the tube wall of the tubular bracket so that the aerosol matrix in the liquid storage housing 211 can enter the atomization channel 220a and be absorbed by the liquid guiding member. The heating member is used to heat the aerosol matrix in the liquid guiding member to vaporize the aerosol matrix.

[0117] As Figure 6 shown, on the side of the third housing 20 opposite to the first housing wall 101, there is a second convex portion 20a, and the exposed part of the third electrical connecting member 24 is located in the second convex portion 20a.

[0118] The second convex portion 20a has a concave area 20b, and the concave area 20b is located at the edge of the second convex portion 20a. The air inlet hole 200b of the atomizer 200 is located in the concave area 20b.

[0119] The second convex portion 20a of the third housing 20 can be engaged with the first concave portion 101b of the first housing 10 for positioning, making it easier to assemble the atomizer 200 and the control component 300. By providing a concave area 20b at the edge of the second convex portion 20a and arranging the air inlet hole 200b of the atomizer 200 in the concave area 20b, when the atomizer 200 is connected to the control component 300, the air inlet hole 200b will not be blocked by the surface of the control component 300, ensuring smooth air intake of the atomizer 200.

[0120] Figure 8 is a schematic diagram of the cooperation between an atomizer and a control component provided by an embodiment of the present application. Figure 8 In it, the approximate flow direction of part of the air flow during user suction is schematically shown by black arrows. As Figure 8 shown, the concave area 20b can be opposite to the air guiding groove 101c, making it easier for the air flow to enter the air inlet hole 200b. There can be two concave areas 20b, and the atomizer 200 can have two air inlet holes 200b, and each concave area 20b is provided with one air inlet hole 200b.

[0121] The induction air passage 200a of the atomizer 200 may be located at the geometric center of the second convex portion 20a, and the two concave regions 20b may be arranged centrosymmetrically with respect to the geometric center of the second convex portion 20a. When connecting the atomizer 200 to the control component 300, even if the atomizer 200 or the control component 300 is rotated by 180°, the induction air passage 200a can still communicate with the detection hole 101a of the control component 300, and the two air inlet holes 200b can be respectively aligned with the two air guide grooves 101c to ensure the smoothness of the air path.

[0122] Figure 9 It is a schematic structural diagram of the power supply of an aerosol generating device provided by an embodiment of the present application. As Figure 9 shown, the power supply 400 includes a fourth housing 40 and a plurality of fourth electrical connectors 41. At least a part of the fourth electrical connectors 41 is exposed outside the fourth housing 40, and the exposed part of the fourth electrical connectors 41 contacts the second electrical connectors 14.

[0123] By directly providing the fourth electrical connectors 41 in the power supply 400, the power supply 400 can directly supply power to the outside through the fourth electrical connectors 41.

[0124] Exemplarily, the exposed parts of the third electrical connectors 24 and the exposed parts of the fourth electrical connectors 41 may be disc-shaped to provide a larger contact area, facilitate contact with the control component 300, and form an electrical connection.

[0125] Compare Figure 6 and Figure 9 As shown, the distribution manner of the exposed parts of the plurality of third electrical connectors 24 on the surface of the third housing 20 may be different from the distribution manner of the exposed parts of the plurality of fourth electrical connectors 41 on the surface of the fourth housing 40. To facilitate comparing the distribution manner of the exposed parts of the plurality of third electrical connectors 24 on the surface of the third housing 20 with the distribution manner of the exposed parts of the plurality of fourth electrical connectors 41 on the surface of the fourth housing 40, a second projection plane is defined, and the second projection plane is parallel to the outer surface of the first housing wall 101 or parallel to the outer surface of the second housing wall 102. For example, the second projection plane may be parallel to the first concave portion 101b.

[0126] In some examples, the orthographic projections of the exposed parts of the plurality of third electrical connectors 24 and the exposed parts of the plurality of fourth electrical connectors 41 on the second projection plane overlap at most partially.

[0127] The exposed part of the third electrical connector 24 is used to contact the first electrical connector 13 of the control component 300 to form an electrical connection, and the exposed part of the fourth electrical connector 41 is used to contact the second electrical connector 14 of the control component 300 to form an electrical connection.

[0128] By adopting the design that the exposed parts of the plurality of third electrical connectors 24 and the exposed parts of the plurality of fourth electrical connectors 41 overlap at most in the orthographic projection on the second projection plane, the distribution manners of the third electrical connectors 24 and the fourth electrical connectors 41 are different. In this way, even if the user mistakenly connects the power supply 400 directly to the atomizer 200, the plurality of third electrical connectors 24 and the plurality of fourth electrical connectors 41 cannot come into contact to form an electrical connection, and the circuit will not be turned on, which can avoid damaging the aerosol generating device.

[0129] In some examples, the orthographic projections of the exposed parts of the plurality of third electrical connectors 24 and the exposed parts of the plurality of fourth electrical connectors 41 on the second projection plane may also overlap at most partially rotationally symmetrically.

[0130] So that no matter how the user rotates the atomizer 200 or the power supply 400, it is impossible to align the plurality of third electrical connectors 24 with the plurality of fourth electrical connectors 41 to directly turn on the circuit between the atomizer 200 and the power supply 400, which can avoid damaging the aerosol generating device.

[0131] Such as Figure 9 As shown, the side of the fourth housing 40 opposite to the second housing wall 102 has a second concave portion 40a, and the exposed part of the fourth electrical connector 41 is located in the second concave portion 40a.

[0132] When the power supply 400 is connected to the control component 300, the second concave portion 40a can be attached to the first convex portion 102a for positioning, which is convenient for the connection between the power supply 400 and the control component 300.

[0133] The power supply 400 may further include a battery, and the battery is located in the fourth housing 40.

[0134] The above-described embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application.
