[0051] The present application is described in detail below with reference to the accompanying drawings and embodiments.

[0052] See also Figures 1 to 4 , Figure 1 A schematic diagram of the overall structure of an aerosol generating device provided in one embodiment of the present application; Figure 2 for Figure 1 A cross-sectional view of the aerosol generating device taken along the line AA;

[0053] Figure 3 for Figure 1 A BB sectional view of the aerosol generating device shown; Figure 4 for Figure 1 The disassembly diagram of the aerosol generating device is shown. In this embodiment, an aerosol generating device is provided for atomizing an aerosol generating substrate to form an aerosol. The aerosol generating substrate includes a liquid substrate, such as oils with added aroma components, liquid medicine, etc. The aerosol generating device can be used in different fields, such as medical treatment, beauty, leisure smoking, etc. The aerosol generating device includes an atomizer 10 and a power supply host 20.

[0054] like Figure 2 and Figure 3 As shown, the nebulizer 10 includes an atomizing component 11 and a first air inlet 131. The atomizing component 11 is used to atomize the aerosol generating matrix to form an aerosol when powered on; and an atomizing airway 110 is formed in the atomizing component 11, and the aerosol formed by atomization flows out of the nebulizer 10 through the atomizing airway 110. The first air inlet 131 is directly connected to external gas, such as air. The power supply host 20 is detachably connected to the nebulizer 10, and is used to supply power to the nebulizer 10. Among them, the power supply host 20 and the nebulizer 10 cooperate to form an air inlet cavity 230, and the air inlet cavity 230 is connected to the first air inlet 131. When the user inhales, the external gas enters the air inlet cavity 230 through the first air inlet 131, and enters the nebulizer 10 to bring out the aerosol.

[0055] In some embodiments, Figure 2 As shown, a first magnetic member 21 is provided on one side surface of the power supply host 20 facing the atomizer 10, and a second magnetic member 12 is provided on one side surface of the atomizer 10 facing the power supply host 20, and a position corresponding to the first magnetic member 21 of the power supply host 20 is provided. The power supply host 20 and the atomizer 10 are connected and fixed by the magnetic adsorption force between the first magnetic member 21 and the second magnetic member 12. Among them, the number of the first magnetic member 21 and the second magnetic member 12 can be two, and a first magnetic member 21 and a second magnetic member 12 are arranged opposite to each other and attract each other. The two first magnetic members 21 are respectively arranged at positions close to the edge of the power supply host 20 along the first direction X of the power supply host 20 to improve the connection stability between the power supply host 20 and the atomizer 10.

[0056] The first magnetic attraction member 21 and the second magnetic attraction member 12 may be magnets.

[0057] The specific structure of the power supply host 20 is introduced below.

[0058] See also Figure 5 , Figure 5 The schematic diagram of the overall structure of the power supply host provided in one embodiment of the present application; the power supply host 20 includes a first shell 22, the first shell 22 has a connection surface, the connection surface faces the atomizer 10, and is used to connect with the atomizer 10; and the connection surface of the power supply host 20 is provided with an air inlet groove 23; the groove wall of the air inlet groove 23 cooperates with the bottom of the atomizer 10, that is, with the end of the atomizer 10 facing the power supply host 20 to form an air inlet cavity 230. Among them, by providing the air inlet groove 23 on the connection surface of the first shell 22 for connecting with the atomizer 10; after the power supply host 20 is connected to the atomizer 10, the external gas can directly enter the atomizer 10 from the surface of the power supply host 20 close to the atomizer 10, shortening the air inlet path and reducing the inhalation resistance.

[0059] In some embodiments, the first housing 22 includes a shell 221 and a cover 222. The shell 221 is a hollow structure with one end open. The cover 222 is covered at the open end of the shell 221 and cooperates with the shell 221 to form a storage space, and the power supply, bracket and other components of the power supply host 20 are all accommodated in the storage space. In this embodiment, the air inlet groove 23 is specifically formed on the side surface of the cover 222 away from the shell 221, that is, the outer surface of the cover 222.

[0060] In a specific embodiment, the outer surface of the cover 222 is convex in a direction away from the housing 221 and defines a boss 24. The air inlet groove 23 is specifically formed on a side surface of the boss 24 away from the housing 221, that is, formed on a side surface of the boss 24 facing the atomizer 10. In this specific embodiment, Figure 4 As shown, a groove 132 is formed at the bottom of the atomizer 10, and the boss 24 is embedded in the groove 132 of the atomizer 10. The groove wall of the air inlet groove 23 on the boss 24 cooperates with the groove wall of the groove 132 of the atomizer 10 to form an air inlet cavity 230. In this solution, the boss 24 is embedded in the groove 132 to achieve the connection between the atomizer 10 and the power supply host 20. On the one hand, it is convenient for the precise positioning of the atomizer 10 and the power supply host 20; on the other hand, it can achieve a certain sealing effect on the air inlet cavity 230.

[0061] This application is Figure 5 Taking the structure shown as an example, the first direction X is defined as the length direction of the power supply host 20 , and the second direction Y is defined as the width direction of the power supply host 20 .

[0062] In one embodiment, the air inlet groove 23 includes a first groove body 231 and a second groove body 232 that are connected. The first groove body 231 extends to the first side edge of the connection surface, and the first groove body 231 is configured to be connected to the first air inlet hole 131 of the atomizer 10; the second groove body 232 is configured to be connected to the atomization airway 110 of the atomizer 10. In this way, the external gas can directly enter the first air inlet hole 131 of the atomizer 10, and directly enter the air inlet groove 23 through the first groove body 231, so as to enter the atomizer 10 through the surface of the power supply mainframe 20 close to the atomizer 10; in this solution, the external gas can enter the atomizer 10 without flowing through the interior or side wall of the power supply mainframe 20, shortening the air inlet path and reducing the inhalation resistance.

[0063] In one embodiment, the air inlet groove 23 further includes a third groove body 233 connected to the second groove body 232, the first groove body 231 and the third groove body 233 are arranged on both sides of the second groove body 232, and the third groove body 233 extends to the second side edge of the connecting surface opposite to the first side edge, and the first groove body 231 or the third groove body 233 is configured to be connected to the first air inlet hole 131 of the atomizer 10. In this way, when the atomizer 10 is installed with the power supply host 20, the first air inlet hole 131 of the atomizer 10 can be connected to the first groove body 231 to achieve the connection between the first air inlet hole 131 and the air inlet groove 23, and the atomizer 10 can have a first installation state relative to the power supply host 20. Or the first air inlet hole 131 is connected to the third groove body 233 to achieve the connection between the first air inlet hole 131 and the air inlet groove 23, and the atomizer 10 can have a second installation state different from the first installation state relative to the power supply host 20. This solution can ensure the communication between the first air inlet 131 and the air inlet slot 23 regardless of the installation state of the atomizer 10, thus playing a certain foolproof role. The first slot body 231 and the third slot body 233 can be arranged along the second direction Y on both sides of the second slot body 232.

[0064] In a specific embodiment, after the atomizer 10 is connected to the power supply host 20, all the first air inlet holes 131 on the atomizer 10 can be directly connected to the first slot body 231 or the third slot body 233 to ensure that each first air inlet hole 131 can be connected to the air inlet slot 23 through the first slot body 231 or the third slot body 233. Specifically, the cross-section of the first slot body 231 and the third slot body 233 can be rectangular. Among them, the aperture of the connection between the first slot body 231 and the second slot body 232 is smaller than the minimum aperture of the first slot body 231 and the second slot body 232. The aperture of the connection between the third slot body 233 and the second slot body 232 is smaller than the minimum aperture of the third slot body 233 and the second slot body 232.

[0065] In one embodiment, the power supply host 20 also includes a power supply electrode 25, an airflow sensor 26 and a blocking platform 28. The power supply electrode 25 is disposed in the second slot 232, and is used to be electrically connected to the contact electrode 18 of the atomizer 10. The power supply electrode 25 is located at the central position of the power supply host 20, that is, at the central position of the connection surface; and the power supply electrode 25 is symmetrically arranged with respect to the center of the power supply host 20; that is, it is symmetrically arranged with respect to the center of the connection surface. In this way, when the atomizer 10 is in the first installation state or the second installation state, the effective contact and electrical connection between the power supply electrode 25 and the atomizer 10 can be ensured. It should be noted that on the plane where the connection surface is located, any straight line passing through the center of the connection surface is symmetrical about the center of the connection surface. The central position of the connection surface refers to the area corresponding to the circle with the center as the center and a preset length as the radius.

[0066] The power supply electrode 25 includes at least two conductive electrodes, at least two of which have opposite polarities. There are at least two contact electrodes 18, one contact electrode 18 corresponds to one conductive electrode, and is configured to be in electrical contact with the corresponding conductive electrode.

[0067] In a specific embodiment, the power supply electrode 25 includes a first conductive electrode, a second conductive electrode and a third conductive electrode; the first conductive electrode and the third conductive electrode are arranged on both sides of the second conductive electrode, and the polarity of the first conductive electrode and the third conductive electrode is opposite to that of the second conductive electrode. The contact electrode 18 includes a first contact electrode, a second contact electrode and a third contact electrode. When the atomizer 10 is in the first installation state, the first conductive electrode is electrically connected to the first contact electrode, the second conductive electrode is electrically connected to the second contact electrode, and the third conductive electrode is electrically connected to the third contact electrode. When the atomizer 10 is in the second installation state, the first conductive electrode is electrically connected to the third contact electrode, the second conductive electrode is electrically connected to the second contact electrode, and the third conductive electrode is electrically connected to the first contact electrode.

[0068] The blocking platform 28 is arranged on the bottom wall of the second slot body 232, and cooperates with the side wall of the second slot body 232 to form the first guide groove 29A and the second guide groove 29B; the two ends of the first guide groove 29A are respectively connected to the first slot body 231 and the second slot body 232; and the bottom wall of the first guide groove 29A is provided with an airflow hole 27, and the airflow sensor 26 is connected to the second slot body 232 through the airflow hole 27, which is used to sense the airflow information to control the opening or closing of the power supply host 20. The airflow sensor 26 can be a microphone. The second guide groove 29B is configured to be connected to the atomization airway 110 of the atomizer 10, and the two ends of the second guide groove 29B are also respectively connected to the first slot body 231 and the third slot body 233. The power supply electrode 25 is specifically arranged on the blocking platform 28.

[0069] The above scheme can divert the airflow entering the second slot body 232 through the blocking platform 28, so that part of the airflow directly enters the atomizing airway 110, and part of the airflow enters the airflow hole 27, ensuring that the airflow sensor 26 can sense the airflow and control the opening and closing of the power supply host 20; and reduce the situation where most of the airflow entering the second slot body 232 is sucked into the atomizing airway 110, and the airflow sensor 26 cannot sense the airflow.

[0070] In a specific embodiment, see Figure 5The first slot body 231 and the third slot body 233 can be respectively arranged on both sides of the second slot body 232 along the width direction (i.e., the second direction Y) of the power supply mainframe 20; the blocking platform 28 specifically extends along the width direction of the power supply mainframe 20. A plurality of conductive electrodes are arranged on the blocking platform 28 at intervals along the width direction of the power supply mainframe 20. Specifically, the air inlet slot 23 can be symmetrically arranged along the central axis of the width direction of the power supply mainframe 20; and / or the air inlet slot 23 can be symmetrically arranged along the central axis of the length direction of the power supply mainframe 20.

[0071] In one embodiment, in combination Figure 5 , the second slot body 232 includes a first side wall, a second side wall, a third side wall and a fourth side wall. The first side wall and the second side wall are inclined at a preset angle, and the first side wall and the second side wall cooperate with the blocking platform 28 to form a first guide groove 29A. The third side wall and the fourth side wall are also inclined at a preset angle, and the third side wall and the fourth side wall cooperate with the blocking platform 28 to form a second guide groove 29B. Among them, the first side wall is inclined from one end close to the first slot body 231 toward the airflow hole 27; the second side wall is inclined from one end close to the third slot body 233 toward the airflow hole 27. In this way, the inclined first side wall or the second side wall can be used to guide the gas entering the first guide groove 29A. The preset angle can be selected and set according to actual conditions. The airflow hole 27 can be specifically located at the intersection of the first side wall and the second side wall of the first guide groove 29A. The intersection of each side wall can be in an arc shape.

[0072] Specifically, the first side wall and the fourth side wall are also tilted at a certain angle; the second side wall and the third side wall are also tilted at a certain angle. The second slot body 232 can be specifically in a rhombus shape or a structure similar to a rhombus shape.

[0073] The power supply host 20 provided in this embodiment is configured such that an air inlet groove 23 is disposed on a connection surface of the first shell 22 for connecting with the atomizer 10; and the air inlet groove 23 includes a first groove body 231 and a second groove body 232 that are connected, wherein the first groove body 231 extends to a first side edge of the connection surface, and the first groove body 231 is configured to be connected with a first air inlet hole 131 of the atomizer 10, and the first air inlet hole 131 is connected with external gas; the second groove body 232 is configured to be connected with an atomizing airway 110 of the atomizer 10; in this way, external gas can directly enter from the first air inlet hole 131 of the atomizer 10, and directly enter the atomizer 10 from the surface of the power supply host 20 close to the atomizer 10, thereby shortening the air inlet path and reducing the inhalation resistance.

[0074] The specific structure of the atomizer 10 is introduced below.

[0075] See also Figure 6 , Figure 6 for Figure 2Schematic diagram of the structure of the atomizer; the atomizer 10 also includes a base 13, a second outer shell 14, an inner shell 15, a first sealing member 16A, a circuit board 17 and a contact electrode 18.

[0076] The second housing 14 is disposed on the base 13 and cooperates with the base 13 to form a receiving cavity. All first air inlet holes 131 are specifically opened on the side wall of the second housing 14 and penetrate the side wall of the second housing 14. In one embodiment, the number of the first air inlet holes 131 is multiple, and the multiple first air inlet holes 131 are arranged at intervals along the circumferential direction of the second housing 14; for example, the number of the first air inlet holes 131 is three, and the three first air inlet holes 131 are arranged at intervals; the following embodiments are described by taking this as an example.

[0077] In one embodiment, in combination Figure 3 and Figure 6 The base 13 is provided with a second air inlet hole 133 and a third air inlet hole 134. The second air inlet hole 133 is directly connected to the first air inlet hole 131 and is directly connected to the first slot body 231 or the third slot body 233 of the air inlet slot 23 of the power supply host 20. When there are multiple first air inlet holes 131, the second air inlet hole 133 can be directly connected to one or more of the multiple first air inlet holes 131. In a specific embodiment, see Figure 7 , Figure 7 A schematic diagram of the structure of the base provided in an embodiment of the present application after being connected to the power supply host; there are three first air inlet holes 131, and the second air inlet hole 133 is directly connected to one of the first air inlet holes 131 located at the two side edges of the three first air inlet holes 131, and the other two first air inlet holes 131 are blocked by the side wall of the base 13. Compared with the solution in which the second air inlet hole 133 is connected to the first air inlet hole 131 located in the middle of the three first air inlet holes 131, the air intake effect is better.

[0078] In a specific embodiment, see Figure 4 and Figure 6 A groove 132 is formed on the side surface of the base 13 facing away from the second shell 14. The second air inlet hole 133 is specifically opened in the groove wall of the groove 132, penetrates the groove wall of the groove 132, and is connected with a first air inlet hole 131; the other first air inlet holes 131 can be blocked by the groove wall of the groove 132.

[0079] Of course, in other embodiments, a plurality of second air inlet holes 133 may also be provided on the groove wall of the groove 132, and one second air inlet hole 133 corresponds to one first air inlet hole 131, and may be connected to the corresponding first air inlet hole 131. In this embodiment, the atomizer 10 further includes an air regulating assembly (not shown), which is used to cover or expose part of the first air inlet hole 131 to adjust the connection between the plurality of second air inlet holes 133 and the plurality of first air inlet holes 131. Specifically, the air regulating assembly includes a shielding plate, which can be rotated along the circumferential direction of the first housing 22 to cover or expose one or more first air inlet holes 131, thereby controlling whether these first air inlet holes 131 are inlet to meet the air intake demand. It can be understood that when the air intake does not meet the requirements, the shielding plate can be rotated counterclockwise to expose multiple or all first air inlet holes 131, so that external gas can be inlet through multiple first air inlet holes 131 at the same time. When a small amount of air intake is required, the shielding plate can be rotated clockwise to cover a portion of the first air intake holes 131 , so that air can be taken in through one or a portion of the first air intake holes 131 .

[0080] The third air inlet hole 134 is connected to the atomizing air passage 110 of the atomizing assembly 11, and is directly connected to the second slot body 232 of the air inlet slot 23. That is, the external air enters the air inlet slot 23 through the first air inlet hole 131 and the second air inlet hole 133 in sequence, and enters the third air inlet hole 134 through the air inlet slot 23, and then enters the atomizing assembly 11, so as to bring out the aerosol formed by the atomization of the atomizing assembly 11.

[0081] In a specific embodiment, after the atomizer 10 is connected to the power supply host 20, the first orthographic projection of the third air inlet 134 of the atomizer 10 on the power supply host 20 is located in the second guide groove 29B of the power supply host 20, and the third side wall of the power supply host 20 is inclined from the end close to the third groove body 233 toward the first orthographic projection; the fourth side wall of the power supply host 20 is inclined from the end close to the first groove body 231 toward the first orthographic projection.

[0082] By arranging the airflow holes 27 on both sides of the blocking platform 28, part of the airflow entering the second slot 232 can enter the atomizer 10 through the third air inlet hole 134 through the blocking platform 28, and part of the airflow enters the airflow hole 27, thereby ensuring the normal operation of the airflow sensor 26 and the atomizer 10. In addition, by arranging the third side wall and the fourth side wall at an angle, the airflow entering the second guide groove 29B can be guided to the position where the first orthographic projection is located, thereby improving the air intake efficiency of the third air inlet hole 134.

[0083] Specifically, the first orthographic projection of the third air inlet 134 of the atomizer 10 on the power supply host 20 may be located near the intersection of the third side wall and the fourth groove wall of the second groove body 232 .

[0084] The inner shell 15 is arranged on the base 13, and cooperates with the base 13 and the atomizing assembly 11 to form a liquid storage cavity. Liquid storage cotton may be arranged in the liquid storage cavity to store the aerosol generating matrix.

[0085] like Figure 6 As shown, the first sealing member 16A is provided on the base 13, and is used to seal the liquid storage cavity, and cooperates with the base 13 to form a receiving cavity. In a specific embodiment, a groove is provided on a side surface of the first sealing member 16A facing the base 13, and the groove cooperates with a side surface of the base 13 facing the first sealing member 16A to form a receiving cavity. All sealing members involved in this application can be structural members such as plastics and silicone.

[0086] The circuit board 17 is disposed in the accommodating cavity and is electrically connected to the atomizing assembly 11. The circuit board 17 may be a flexible printed circuit (FPC).

[0087] The contact electrode 18 is electrically connected to the circuit board 17 and is used to contact and electrically connect with the power supply electrode 25 of the power supply host 20, thereby realizing the electrical connection between the power supply host 20 and the atomizer 10. Figure 6 and Figure 2 The base 13 is also provided with a first lead hole 135, which passes through the upper and lower surfaces of the base 13 and is directly connected to the accommodating cavity. The contact electrode 18 extends from the side where the accommodating cavity is located into the first lead hole 135, and is exposed through the first lead hole 135 on the side of the base 13 away from the inner shell 15. Specifically, the end surface of the end of the contact electrode 18 away from the circuit board 17 is flush with the side of the base 13 away from the circuit board 17; or the end of the contact electrode 18 away from the circuit board 17 extends out of the side of the base 13 away from the circuit board 17.

[0088] In a specific embodiment, in combination Figure 6 , the circuit board 17 extends to the center of the base 13, and the contact electrode 18 is symmetrically arranged with respect to the center of the atomizer 10; the contact electrode 18 is specifically in contact and electrically connected with the portion of the circuit board 17 extending to the center of the base 13. The first lead hole 135 is specifically opened at the center of the base 13, so that the positive projection of the contact electrode 18 on the base 13 is located at the center of the base 13, thereby ensuring that the atomizer 10 and the power supply host 20 can be in contact and electrically connected with the power supply electrode 25 of the power supply host 20 whether the atomizer 10 and the power supply host 20 are installed forward or reverse.

[0089] In one embodiment, the atomizer 10 further includes a second sealing member 16B, which is disposed in the first lead hole 135 and between the inner wall surface of the first lead hole 135 and the contact electrode 18. In this way, the contact electrode 18 can be fixed and external water vapor can be reduced from entering the accommodating cavity.

[0090] In a specific embodiment, a second lead hole 161 is provided at a position of the first seal 16A corresponding to the groove body; the atomizer assembly 11 includes an atomizer core body and an atomizer electrode 111 electrically connected to the atomizer core body. A portion of the atomizer electrode 111 passes through the second lead hole 161 from the side of the first seal 16A away from the base 13 and is electrically connected to the circuit board 17. The atomizer core body includes an atomizer tube, an atomizer net and liquid absorbent cotton. A liquid inlet is provided on the atomizer tube; the liquid absorbent cotton is clamped between the atomizer tube and the liquid absorption surface. The aerosol generating matrix in the liquid storage chamber enters the side where the liquid absorbent cotton is located through the liquid inlet; the liquid absorbent cotton further guides the aerosol generating matrix to the atomizer net, so as to heat and atomize the aerosol generating matrix through the atomizer net, thereby forming an aerosol.

[0091] Among them, the orthographic projection of the second lead hole 161 along the height direction Z of the atomizer 10 can fall within the accommodating cavity, and along the direction of the second lead hole 161 toward the accommodating cavity, the aperture of the second lead hole 161 toward one end of the accommodating cavity gradually increases, that is, the second lead hole 161 is trumpet-shaped. In this way, during the preparation process of the atomizer 10, it is convenient to dispense glue in the second lead hole 161 to form a third seal. That is, the atomizer 10 also includes a third seal (not shown), which is arranged in the second lead hole 161 and is located between the inner wall surface of the second lead hole 161 and the atomizing electrode 111. The third seal can not only fix the atomizing assembly 11 to prevent the atomizing assembly 11 from shaking; at the same time, it can reduce the risk of leakage of the aerosol generating matrix or aerosol through the second lead hole 161.

[0092] The atomizer 10 provided in this embodiment forms a first air inlet hole 131 directly connected to the external air on the side wall of the atomizer 10. After the atomizer 10 is connected to the power supply host 20, the external air can directly enter the air inlet chamber 230 from the side wall of the atomizer 10 to enter the atomizer 10. Compared with the solution of forming the first air inlet hole 131 on the side wall or bottom wall of the power supply host 20, the path for the airflow to flow from the side wall or bottom wall of the power supply host 20 to the connecting surface of the power supply host 20 is omitted, thereby effectively shortening the air intake path and reducing the inhalation resistance.

[0093] The above are only implementation methods of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
