[0062] An embodiment of the present application provides an aerosol generating device for generating aerosol for a user to inhale.

[0063] See Figures 1 to 3 、 Figures 14 to 16 、 Figures 20 to 22 、 Figures 24 to 26The aerosol generating device includes a functional component 10 and a power supply component 20.

[0064] The functional assembly 10 includes an additional oil tank 40 and an atomizer 30. The additional oil tank 40 is provided with an additional storage chamber 40a. The atomizer 30 is located on one side of the additional oil tank 40 along the first direction. The atomizer 30 is provided with a main storage chamber 30a. The main storage chamber 30a can communicate with the additional storage chamber 40a.

[0065] The power supply assembly 20 is located on one side of the functional assembly 10 along the second direction, the first direction intersects the second direction, and the power supply assembly 20 is electrically connected to the atomizer 30;

[0066] The functional component 10 and the power supply component 20 are detachably connected.

[0067] The functional component 10 refers to the portion of the aerosol generating device that can be used to realize the function of converting the aerosol generating substrate into aerosol.

[0068] The additional storage chamber 40a is used to store an aerosol-generating substrate. The main storage chamber 30a is used to store an aerosol-generating substrate.

[0069] The atomizer 30 includes an atomizing core 331, which defines an atomizing chamber 331a. The atomizing chamber 331a is separated from the main storage chamber 30a. The atomizing core 331 continuously converts the aerosol-generating substrate within the main storage chamber 30a into aerosol. As the aerosol in the main storage chamber 30a is consumed, the aerosol-generating substrate within the additional storage chamber 40a is continuously replenished. This reduces the risk of dry burning of the atomizing core 331 and extends the service life of the aerosol generating device.

[0070] The power supply assembly 20 is used to provide electrical energy to the atomizer 30 .

[0071] The atomizer 30 and the additional oil tank 40 are arranged along a first direction, so that the flow of the aerosol generating substrate therebetween is mainly along the first direction.

[0072] It is understandable that the power supply assembly 20 includes various types of electronic components for realizing the normal operation of the atomizer 30. The aerosol generating matrix and the aerosol formed after the aerosol condenses may cause problems such as short circuits in the electronic components and may also corrode the electronic components.

[0073] The power supply assembly 20 is located to one side of the functional assembly 10 along the second direction. That is, the atomizer 30, the additional oil tank 40, and the power supply assembly 20 are not arranged along the first direction. This facilitates keeping the power supply assembly 20 away from the aerosol-generating substrate flowing between the atomizer 30 and the additional oil tank 40.

[0074] The power supply assembly 20 is detachably connected to each other. Thus, if either one is damaged, it can be separated and repaired or replaced.

[0075] The aerosol generating device in the embodiment of the present application, by arranging the functional component 10 and the power supply component 20 in a direction different from the arrangement direction of the atomizer 30 and the additional oil tank 40, is helpful in reducing the risk of aerosol generating matrix, condensate and other fluids in the atomizer 30 and the accessory oil tank penetrating into the power supply component 20 and damaging the electronic components in the power supply component 20, thereby extending the service life of the power supply component 20.

[0076] In some embodiments, the first direction is perpendicular to the second direction, so as to facilitate reducing the outer dimensions of the aerosol generating device.

[0077] It is understandable that when the power supply assembly 20 and the functional assembly 10 are separated, the power supply assembly 20 and the atomizer 30 are no longer electrically connected.

[0078] In some embodiments, the atomizer 30 is provided with an atomizing chamber 331 a , and the functional component 10 is provided with an air outlet channel 10 a , which is connected to the outside of the aerosol generating device and the atomizing chamber 331 a .

[0079] When the user inhales the aerosol, the outlet of the air outlet channel 10a is connected to the user's oral cavity, so that the aerosol in the atomization cavity 331a enters the user's oral cavity through the air outlet channel 10a.

[0080] In some embodiments, see Figure 3 and Figure 16 The additional oil tank 40 is provided with an air outlet channel 10a, which is connected to the outside of the aerosol generating device. The atomizer 30 is located on the outlet side of the additional oil tank 40 away from the air outlet channel 10a along the first direction.

[0081] In this way, it is beneficial to set the air outlet channel 10a through the additional oil tank 40, thereby extending the air flow path of the aerosol discharged from the atomizer 30 out of the aerosol generating device, which is beneficial to reduce the temperature of the aerosol to a suitable temperature range, and reduce the problem of burnt mouth during use by the user; by replacing the additional oil tank 40, the health risks brought to the user by health problems such as fungus growth in the air outlet channel 10a are reduced.

[0082] In some embodiments, see Figure 26 The atomizer 30 is provided with an air outlet channel 10a, which is communicated with the outside of the aerosol generating device. The additional oil tank 40 is located on the outlet side of the atomizer 30 away from the air outlet channel 10a along the first direction.

[0083] That is, the air outlet passage 10 a does not pass through the additional oil tank 40 .

[0084] This is beneficial for increasing the volume of the additional storage chamber 40a within a limited space, shortening the flow path of the aerosol, reducing the loss of the aerosol, reducing the probability that the aerosol generating matrix in the additional storage chamber 40a can always flow into the main storage chamber 30a, reducing the probability of oversaturation of the aerosol generating matrix in the main storage chamber 30a, and improving the taste of the aerosol.

[0085] In some embodiments, see Figure 22 The atomizer 30 is provided with an air outlet channel 10a, which is communicated with the outside of the aerosol generating device, and an extending direction of the air outlet channel 10a intersects with the first direction.

[0086] This helps to increase the volume of the additional storage chamber 40a within a limited space.

[0087] In some embodiments, the first direction is substantially vertical during use of the aerosol generating device by a user.

[0088] In some embodiments, see Figure 9 and Figure 18 One of the functional component 10 and the power supply component 20 is provided with a receiving cavity 20a, and the receiving cavity 20a is open along the second direction so that a portion of the other of the functional component 10 and the power supply component 20 can enter the receiving cavity 20a.

[0089] In this way, the inner wall of the receiving cavity 20a can shield the detachable connection position and electrical connection position of the functional component 10 and the power component 20, reducing the risk of connection failure and electrical connection failure. The specific method of achieving the detachable connection between the functional component 10 and the power component 20 is not limited.

[0090] In some embodiments, see Figure 3 、 Figure 8 and Figure 9 The power supply assembly 20 includes a first adsorption member 21 , and the atomizer 30 includes a second adsorption member 31 . The first adsorption member 21 and the second adsorption member 31 can generate an adsorption force along at least the second direction.

[0091] In this way, the adsorption force between the first adsorption member 21 and the second adsorption member 31 maintains the power supply assembly 20 and the atomizer 30 in contact, which helps maintain an electrical connection between the two. The user applies a force in the second direction opposite to the adsorption force to the power supply assembly 20 and the atomizer 30 to overcome the adsorption force, thereby separating the atomizer 30 and the power supply assembly 20, achieving the purpose of separating the two, and the operation is simple.

[0092] In some embodiments, see Figure 3 、 Figure 8 and Figure 9 The additional oil tank 40 includes a third adsorption member 41 , and an adsorption force along the second direction can be generated between the first adsorption member 21 and the third adsorption member 41 .

[0093] In this way, the adsorption force between the first adsorption member 21 and the third adsorption member 41 maintains contact between the power assembly 20 and the functional component 10, which helps maintain electrical connection between the power assembly 20 and the atomizer 30. The user applies a force in the second direction opposite to the adsorption force to the power assembly 20 and the atomizer 30, overcoming the adsorption force and separating the atomizer 30 from the power assembly 20, thereby achieving the purpose of separating the two, and the operation is simple.

[0094] In some embodiments, see Figure 9 The number of the first adsorption components 21 is at least two, at least one first adsorption component 21 is used to generate adsorption force with the third adsorption component 41 , and at least one first adsorption component 21 is used to generate adsorption force with the second adsorption component 31 .

[0095] This helps to make the connection between the power supply component 20 and the functional component 10 more stable.

[0096] The number of the second adsorption components 31 may be one or more; the number of the third adsorption components 41 may be one or more.

[0097] In some embodiments, the first adsorption component 21, the second adsorption component 31 and the third adsorption component 41 are all magnets, and the polarity of the second adsorption component 31 and the third adsorption component 41 is opposite to the polarity of the first adsorption component 21, so as to achieve mutual attraction between the first adsorption component 21 and the second adsorption component 31, and mutual attraction between the first adsorption component 21 and the third adsorption component 41 by the attraction of opposite poles.

[0098] In some embodiments, see Figure 18 and Figure 19 The aerosol generating device also includes a guide groove 10b and a guide portion 22. The power supply component 20 is provided with one of the guide groove 10b and the guide portion 22, and the functional component 10 is provided with the other. The extension direction of the guide groove 10b is the same as the extension direction of the guide portion 22 and intersects with the second direction. The guide groove 10b is closed on both sides along the second direction, and at least one end of the guide groove 10b along its extension direction is open so that the guide portion 22 can enter and exit the guide groove 10b along the extension direction of the guide groove 10b.

[0099] The guide portion 22 enters the guide groove 10b from the opening of the guide groove 10b and moves along the extension direction of the guide groove 10b. Constrained by the inner walls of the guide groove 10b along the second direction, the guide portion 22 is difficult to escape from the guide groove 10b in the second direction, thereby limiting the relative movement between the functional assembly 10 and the power supply assembly 20 in the second direction.

[0100] In this way, through the cooperation between the guide portion 22 and the guide groove 10b, the functional component 10 and the power supply component 20 are detachably connected, and the structure is simple and easy to operate.

[0101] The specific number of the guide portion 22 and the guide groove 10b is not limited, and can be one or more.

[0102] In some embodiments, the guide groove 10b is provided only in the atomizer 30; in some embodiments, the guide groove 10b is provided only in the additional oil tank 40; in other embodiments, see Figure 18 The guide groove 10b includes a first sub-groove 10c and a second sub-groove 10d. The first sub-groove 10c is located in the atomizer 30, and the second sub-groove 10d is located in the additional oil tank 40. In the projection perpendicular to the extension direction of the guide groove 10b, the projection of the first sub-groove 10c coincides with the projection of the second sub-groove 10d.

[0103] It can be understood that both the guide portion 22 and the guide groove 10b extend in a straight line direction.

[0104] In some embodiments, see Figure 18 The functional component 10 is provided with a limiting portion 12, which is provided at one end of the guide groove 10b away from its open position along its extension direction. In the projection perpendicular to the extension direction of the guide groove 10b, at least part of the projection of the limiting portion 12 is located within the projection range of the guide groove 10b. When the atomizer 30 is electrically connected to the power supply component 20, the limiting portion 12 abuts against the guide portion 22, so that the user can confirm that the relative position of the functional component 10 and the power supply component 20 meets the requirements during the installation process.

[0105] It is understandable that during use of the aerosol generating device, it is necessary to reduce the probability of relative movement between the guide portion 22 and the guide groove 10b, which may cause failure of the electrical connection between the atomizer 30 and the power supply assembly 20 .

[0106] In some embodiments, see Figure 16 、 Figure 18 and Figure 19The aerosol generating device also includes an elastic portion 23 and a stop portion 11. The power supply assembly 20 is provided with one of the elastic portion 23 and the stop portion 11, and the functional assembly 10 is provided with the other. The elastic portion 23 can elastically expand and contract perpendicular to the extension direction of the guide groove 10b. When the guide portion 22 is embedded in the guide groove 10b, in the projection perpendicular to the extension direction of the guide groove 10b, at least part of the projection of the elastic portion 23 coincides with the projection of the stop portion 11. When the power supply assembly 20 is electrically connected to the atomizer 30, the elastic portion 23 is located on the side of the stop portion 11 along the extension direction of the guide groove 10b that is away from the opening of the guide groove 10b and the two are abutted along the extension direction of the guide groove 10b.

[0107] After the guide portion 22 is inserted into the guide groove 10b, it moves along the extension direction of the guide groove 10b until the elastic portion 23 abuts the stop portion 11 along the extension direction of the guide groove 10b. The functional component 10 and the power supply component 20 are continuously pushed relative to each other, so that the stop portion 11 squeezes the elastic portion 23 and deforms it until the elastic portion 23 is deformed to a state where it no longer abuts the stop portion 11 along the extension direction of the guide groove 10b. This causes the stop portion 11 to move from the side of the elastic portion 23 closest to the opening of the guide groove 10b to the side away from the opening of the guide groove 10b. In this state, the power supply component 20 is electrically connected to the atomizer 30, and the elastic portion 23 abuts the stop portion 11 along the extension direction of the guide groove 10b. The user then applies a reverse force, causing the guide portion 22 to generate a movement tendency toward the open position of the guide groove 10b, and the stop portion 11 squeezes the elastic portion 23 to deform until the elastic portion 23 is deformed to a state where it no longer abuts the stop portion 11 along the extension direction of the guide groove 10b, causing the stop portion 11 to move from the side of the elastic portion 23 and the opening away from the guide groove 10b to the side close to the opening of the guide groove 10b, allowing the guide portion 22 to continue moving until it is completely out of the guide groove 10b.

[0108] In this way, through the cooperation between the elastic portion 23 and the stop portion 11 , the relative positions of the functional component 10 and the power component 20 along the extending direction of the guide slot 10 b are kept stable.

[0109] There is no limitation on the specific method for achieving elastic deformation of the elastic portion 23. Figure 16 A cavity is provided in the elastic portion 23 to weaken the structural strength of the elastic portion 23 , so as to facilitate deformation of the elastic portion 23 under the extrusion of the stop portion 11 .

[0110] It can be understood that in some embodiments where the limiting portion 12 is provided, when the power supply assembly 20 is electrically connected to the atomizer 30, the elastic portion 23 abuts against the stop portion 11, and the guide portion 22 abuts against the inner wall of one end of the guide groove 10b along its extension direction, thereby fixing the relative positions of the functional assembly 10 and the power supply assembly 20.

[0111] In some embodiments, see Figure 16 、 Figure 18 and Figure 19 Both sides of the elastic portion 23 along the extending direction of the guide groove 10b are inclined surfaces, and both sides of the stop portion 11 along the extending direction of the guide groove 10b are inclined surfaces, so that the stop portion 11 squeezes the elastic portion 23 to deform.

[0112] In some embodiments, see Figure 18 At least part of the inner wall of the receiving cavity 20a is surrounded by a guide groove 10b to make the structure more compact.

[0113] In some embodiments, see Figure 18 At least part of the inner wall of the receiving cavity 20a forms a limiting portion 12 to make the structure more compact.

[0114] The specific method of electrically connecting the atomizer 30 and the power supply assembly 20 is not limited.

[0115] In some embodiments, see Figures 6 to 8 、 Figures 16 to 18 、 Figure 22 and Figure 23 The aerosol generating device includes a first ejector pin 50 and a conductive wire 34. The atomizer 30 is provided with a second mounting hole 30d. At least a portion of the first ejector pin 50 is inserted into the second mounting hole 30d. The conductive wire 34 is electrically connected to the atomizer 30. A portion of the conductive wire 34 is clamped between the inner wall of the second mounting hole 30d and the first ejector pin 50 to electrically connect the conductive wire 34 to the first ejector pin 50. One end of the first ejector pin 50 along the second direction is located on one side of the atomizer 30 along the second direction. A power contact is provided on one surface of the power supply assembly 20 along the second direction. The first ejector pin 50 contacts the power contact to electrically connect the two.

[0116] At least a portion of the first ejector pin 50 is made of a conductive material to provide electrical conductivity. The specific type of the conductive material used is not limited, for example, copper.

[0117] At least a portion of the conductive wire 34 is sandwiched between the inner wall of the second mounting hole 30d and the first ejector pin 50. On the one hand, this achieves electrical conduction between the conductive wire 34 and the first ejector pin 50. On the other hand, the friction between the guide wire, the inner wall of the second mounting hole 30d, and the first ejector pin 50 is utilized to limit the first ejector pin 50 and the guide wire, thereby maintaining a stable electrical conduction state between the two.

[0118] A portion of the conductive wire 34 can be inserted into the second mounting hole 30d in advance, and then the first ejector pin 50 can be pressed into the second mounting hole 30d, so that the conductive wire 34 is clamped between the inner wall of the second mounting hole 30d and the first ejector pin 50. This eliminates the need for welding, bonding, or other methods to fix the conductive wire 34 to the first ejector pin 50, thereby simplifying the assembly steps of the atomizer 30.

[0119] In some embodiments, see Figures 6 to 8 、 Figures 16 to 18 、 Figure 22 and Figure 23 The atomizer 30 includes an atomizing housing 32 and an atomizing assembly 33 . The main storage chamber 30 a is located in the atomizing assembly 33 . The atomizing assembly 33 and the atomizing housing 32 enclose a first chamber 30 b . The conductive wire 34 is at least partially located in the first chamber 30 b .

[0120] In this way, the conductive wire 34 can be protected to a certain extent.

[0121] In some embodiments, see Figure 7 and Figure 17 The end surface of one end of the first ejector pin 50 along the second direction is flush with the end surface of the atomizing housing 32 along the second direction, so as to reduce the probability of the first ejector pin 50 being damaged by collision during the process of disassembling and assembling the functional component 10.

[0122] The specific position of the second mounting hole 30d is not limited.

[0123] In some embodiments, the atomizing housing 32 is provided with a second mounting hole 30d, and the second mounting hole 30d is connected to the first cavity 30b and the outside of the atomizer.

[0124] In other embodiments, see Figures 6 to 8 、 Figures 16 to 18 、 Figure 22 and Figure 23 The atomizer housing 32 is provided with a first mounting hole 30c, which connects the first cavity 30b with the outside of the atomizer 30. At least one of the atomizer assembly 33 and the atomizer housing 32 is provided with a second mounting hole 30d, which is located in the first cavity 30b. The first ejector pin 50 is passed through the first mounting hole 30c and the second mounting hole 30d, and the conductive wire 34 is electrically connected to the atomizer assembly 33.

[0125] The atomizing assembly 33 is used to convert the aerosol-generating substrate into an aerosol.

[0126] The conductive wire 34 is conductive and has a flexible structure so that the conductive wire 34 can be flexibly bent according to the relative position between the electrical connection position of the atomizing assembly 33 and the guide wire and the second mounting hole 30d, thereby improving the adaptability of the installation.

[0127] In some embodiments, see Figure 7 The first mounting hole 30 c is located on one side of the atomizing housing 32 along the second direction so as to shorten the distance from the power supply assembly 20 and facilitate electrical connection between the first ejector pin 50 and the power supply assembly 20 .

[0128] In some embodiments, see Figure 6 The atomizer assembly 33 includes an atomizer core 331 , and the conductive wire 34 is electrically connected to the atomizer core 331 , so that a conductive path is formed between the power supply assembly 20 , the conductive wire 34 and the atomizer core 331 , so that the power supply assembly 20 provides electrical energy to the atomizer core 331 .

[0129] In some embodiments, see Figure 7 and Figure 17 The extending direction of the first mounting hole 30c is the same as that of the second mounting hole 30d. One end of the second mounting hole 30d opens toward the first mounting hole 30c. At least a portion of the first ejector pin 50 can pass through the first mounting hole 30c.

[0130] The extending direction of the first mounting hole 30c is the depth direction of the first mounting hole 30c; the extending direction of the second mounting hole 30d is the depth direction of the second mounting hole 30d.

[0131] That is, when projected perpendicular to the extension direction of the first mounting hole 30c, at least a portion of the projection of the first ejector pin 50 can completely overlap with or be smaller than the projection of the first mounting hole 30c. This facilitates the insertion of at least a portion of the first ejector pin 50 from outside the atomizer housing 32 into the second mounting hole 30d after the atomizer 30 is fully assembled. The inner wall of the first mounting hole 30c can guide and limit the insertion of the first ejector pin 50, facilitating accurate insertion of the first ejector pin 50 into the second mounting hole 30d.

[0132] In some embodiments where the atomizing chamber 331a is in communication with the first chamber 30b, the atomizing housing 32 is provided with an air inlet 32a, which is in communication with the first chamber 30b and the outside of the aerosol generating device.

[0133] It can be understood that the functional component 10 and the power supply component 20 are detachably connected so that there is a seam between the two.

[0134] In some embodiments, see Figure 7 and Figure 17 The atomizing assembly 33 is provided with an atomizing chamber 331 a , the atomizing chamber 331 a is communicated with the first chamber 30 b , and the first ejector pin 50 is sealed and fitted with the inner wall of the first mounting hole 30 c .

[0135] The first ejector pin 50 is in sealing contact with the inner wall of the first mounting hole 30c, so that when the user inhales the aerosol, it is difficult for outside air to enter the first cavity 30b through the first mounting hole 30c, thereby facilitating the formation of negative pressure in the first cavity 30b, so that air outside the aerosol generating device can enter the first cavity 30b and then the atomizing cavity 331a.

[0136] It is understandable that the aerosol remaining in the atomization chamber 331a condenses to form condensate, and the condensate flows into the first chamber 30b.

[0137] In some embodiments, the second mounting hole 30 d and the first ejector pin 50 are interference-fitted to secure a portion of the conductive wire 34 between the inner wall of the second mounting hole 30 d and the first ejector pin 50 .

[0138] In some embodiments, in a projection perpendicular to the extension direction of the atomizing chamber 331 a , the projection of the first ejector pin 50 and the projection of the second mounting hole 30 d are both located outside the projection of the connection position between the atomizing chamber 331 a and the first chamber 30 b , so as to reduce the probability of condensate directly contaminating the first ejector pin 50 and the connection position between the first ejector pin 50 and the conductive wire 34 .

[0139] In some embodiments, see Figure 3 、 Figure 6 、 Figure 16 and Figure 22 The atomizing assembly 33 includes an atomizing chamber 331 a, which is connected to the first chamber 30 b. The atomizer 30 further includes a liquid absorbing component 35, which is located in the first chamber 30 b.

[0140] In this way, the liquid absorbing member 35 can, on the one hand, occupy part of the space in the first cavity 30b so that negative pressure can be formed in the first cavity 30b more quickly; on the other hand, the liquid absorbing member 35 can absorb condensation, thereby reducing the probability of condensation corroding the conductive wire 34 and reducing the risk of condensation leakage.

[0141] The absorbent element 35 is provided with pores therein to absorb the aerosol-generating substrate.

[0142] It is understandable that the pores of the liquid absorbent member 35 can be macroscopically discernible to the naked eye or microscopically invisible to the naked eye, as long as they meet the requirements of absorbing aerosols to generate a matrix through capillary action and allowing airflow to pass through.

[0143] The specific form of the liquid-absorbing member 35 is not limited, for example, cotton wool, sponge, a fiber structure woven and twisted by chemical fibers such as polyester and nylon, etc.

[0144] It is understood that the aerosol generating substrate is wettable relative to the material of the liquid absorbing member 35 , so that the aerosol generating substrate is attached to or absorbed by the liquid absorbing member 35 .

[0145] In some embodiments, see Figure 7 、 Figure 17 and Figure 23 The atomizer 30 includes an elastic fixing seat 36 made of an elastic material, and the second mounting hole 30d extends through the elastic fixing seat 36. The elastic deformation of the elastic fixing seat 36 generates an elastic force on the inner wall of the second mounting hole 30d, which helps to increase the squeezing force between the inner wall of the second mounting hole 30d and the first ejector pin 50 on the conductive wire 34, thereby improving the stability of the electrical conduction between the first ejector pin 50 and the conductive wire 34.

[0146] In some embodiments, the elastic fixing seat 36 is disposed on the atomizing assembly 33 .

[0147] It can be understood that the main storage chamber 30a and the atomization chamber 331a are isolated from each other.

[0148] In some embodiments, the first mounting hole 30c is located on one side of the atomizing housing 32 along the second direction. Figure 3 、 Figure 7 、 Figure 16 and Figure 17 The power supply assembly 20 includes a power supply housing 24, a power supply component 25 and a second ejector pin 26. The power supply housing 24 is provided with a second cavity 24b and a fourth mounting hole 24a. The fourth mounting hole 24a connects the second cavity 24b and the outside of the power supply assembly 20. The fourth mounting hole 24a extends along the second direction. The power supply component 25 is located in the second cavity 24b. At least a portion of the second ejector pin 26 is located in the second cavity 24b and is electrically connected to the power supply component 25. The second ejector pin 26 is disposed in the fourth mounting hole 24a. The second ejector pin 26 can be extended and retracted along the second direction. The second ejector pin 26 can abut against the first ejector pin 50 along the second direction.

[0149] In this way, electrical connection is achieved through contact between the first ejector pin 50 and the second ejector pin 26, thereby achieving electrical connection between the power supply assembly 20 and the atomizer 30; through the extension and retraction of the second ejector pin 26, the second ejector pin 26 can maintain contact with the first ejector pin 50, which is conducive to maintaining the stability of the electrical connection.

[0150] It can be understood that a portion of the second ejector pin 26 forms a power contact.

[0151] The types of electronic components included in the power supply assembly 20 are not limited, such as a power supply 25, a PCB (Printed Circuit Board), an air pressure sensor 28, etc.

[0152] The specific type of the power supply 25 is not limited, such as a lithium battery.

[0153] In some embodiments, see Figure 4 、 Figure 5 、 Figure 8 、 Figures 16 to 18 、 Figure 22 and Figure 23 The functional component 10 is provided with an air flow channel and a first air pressure hole 10e. The outlet and the inlet of the air flow channel are both connected to the outside of the aerosol generating device. The first air pressure hole 10e connects the air flow channel with the outside of the functional component 10. The power supply component 20 includes a power supply shell 24, an elastic mounting seat 27 and an air pressure sensor 28. A second cavity 24b and a third mounting hole are provided in the power supply shell 24. The third mounting hole connects the second cavity 24b with the outside of the power supply component 20. The elastic mounting seat 27 is penetrated by the third mounting hole. The elastic mounting seat 27 is provided with a second air pressure hole 27a. The sensing area of ​​the air pressure sensor 28 is located at the second air pressure hole 27a. When the power supply component 20 is electrically connected to the atomizer 30, the elastic mounting seat 27 is sealed and fitted with the functional component 10, and the second air pressure hole 27a is connected to the first air pressure hole 10e.

[0154] The airflow outside the aerosol generating device enters the airflow channel from the inlet of the airflow channel, mixes with the aerosol in the airflow channel, and is discharged from the outlet of the airflow channel and enters the user's mouth.

[0155] It is understandable that when the user is inhaling, the air pressure in the air flow channel drops, thereby causing the air pressure in the first air pressure hole 10e to drop, thereby causing the air pressure in the second air pressure hole 27a to drop, so that the air pressure sensor 28 can sense the change in air pressure, and then control the power supply 25 to supply power to the atomizer 30.

[0156] The elastic mounting seat 27 is capable of elastic deformation. The elastic mounting seat 27 abuts the functional component 10, causing the elastic mounting seat 27 to deform, thereby reducing the probability of outside air entering the second air pressure hole 27a through the seam between the elastic mounting seat 27 and the functional component 10. This helps the air pressure sensor 28 more accurately sense the negative pressure generated by the user's inhalation in the second air pressure hole 27a, thereby improving the response speed of the aerosol generating device.

[0157] The specific material of the elastic mounting seat 27 is not limited, such as silicone, rubber, etc.

[0158] In some embodiments, the air inlet 32a, the first cavity 30b, the atomizing cavity 331a, and the air outlet channel 10a all form a part of the air flow channel.

[0159] In some embodiments, see Figure 5 and Figure 23The elastic mounting seat 27 includes an elastic skirt 271, which surrounds one end opening of the second air pressure hole 27a. The elastic skirt 271 is inclined in the second direction and extends away from the opening of the second air pressure hole 27a. The elastic skirt 271 is configured to seal against the functional component 10. This allows the elastic skirt 271 to deform more easily under the action of a force in the second direction, thereby improving the sealing performance between the elastic mounting seat 27 and the functional component 10.

[0160] In some embodiments with the atomizing housing 32, the atomizing assembly 33 and the liquid absorbing member 35, see Figure 16 and Figure 17 The atomizing assembly 33 and the atomizing housing 32 are arranged to form a first cavity 30b. The first air pressure hole 10e is located in the atomizing housing 32 and communicates with the first cavity 30b. The liquid absorbing component 35 is located in the first cavity 30b. The first cavity 30b forms a part of the air flow channel.

[0161] In this way, the condensate can be absorbed by the liquid absorber 35 in the first cavity 30 b , thereby reducing the probability of the condensate entering the second air pressure hole 27 a and contacting the air pressure sensor 28 , which is beneficial to extending the service life of the air pressure sensor 28 .

[0162] In some embodiments, see Figure 10 、 Figure 11 and Figure 22 The additional oil tank 40 includes an oil tank housing 42, a mounting plug 43, and an elastic seal 44. The oil tank housing 42 defines a storage space with one side open. The mounting plug 43 seals the open storage space. The mounting plug 43 defines an insertion and extraction passage that connects the additional storage chamber 40a with the exterior of the additional oil tank 40. The elastic seal 44 includes an annular portion 441 and a blocking portion 442. The annular portion 441 is sandwiched between the mounting plug 43 and the oil tank housing 42. The oil tank housing 42, the mounting plug 43, and the elastic seal 44 collectively enclose the additional storage chamber 40a. The blocking portion 442 is connected to the annular portion 441 and blocks the connection between the insertion and extraction passage and the additional storage chamber 40a. A portion of the atomizer 30 can be inserted into the insertion and extraction passage to disengage the blocking portion 442 and open the insertion and extraction passage, thereby connecting the main storage chamber 30a and the additional storage chamber 40a.

[0163] In this way, the sealing oil tank housing 42 and the mounting plug 43 and the plugging and unplugging channel are all made of the same part, which is beneficial to reducing the number of parts in the additional oil tank 40 and reducing the production and assembly costs.

[0164] In some embodiments, see Figure 3 and Figure 13The outer surface of the atomizer assembly 33 is provided with an insert column 332, which extends along the first direction. A liquid inlet channel 332a is provided through the insert column 332, and the liquid inlet channel 332a connects the main storage cavity 30a and the outside of the atomizer assembly 33. The insert column 332 is used to be inserted into the plug-in channel to push the blocking portion 442 to open the plug-in channel.

[0165] In some embodiments including the first cavity 30b, see Figure 12 and Figure 13 The atomizing assembly 33 includes a ventilation channel 33a, which connects the first chamber 30b and the main storage chamber 30a, so that the airflow in the first chamber 30b can enter the main storage chamber 30a and then be replenished into the additional storage chamber 40a, thereby reducing the difficulty of the aerosol generating matrix entering the main storage chamber 30a due to the negative pressure generated in the additional storage chamber 40a.

[0166] In some embodiments where the functional component 10 is provided with an air outlet channel 10a, see Figure 22 The outlet of the air outlet channel 10a is located on a side of the functional component 10 away from the power supply component 20 along the second direction.

[0167] This helps reduce the probability of condensate flowing out of the air outlet channel 10 a adhering to the power supply assembly 20 .

[0168] In some embodiments, the functional component 10 is provided with an air inlet channel, which is in communication with the outside of the aerosol generating device, and an inlet of the air inlet channel is located on one side of the functional component 10 along the first direction.

[0169] The air inlet passage is used for external airflow to enter the interior of the functional component 10 to mix with the aerosol in the atomizing chamber 331a. Therefore, the condensed liquid in the atomizing chamber can enter the air inlet passage.

[0170] This helps reduce the probability of condensate flowing out of the air intake passage adhering to the power supply assembly 20 .

[0171] In some embodiments, see Figure 3 The air intake hole 32a forms a part of the air intake passage, and the inlet of the air intake hole 32a forms the inlet of the air intake passage.

[0172] In some embodiments, see Figure 8 and Figure 9 The first surface 10f of the functional component 10 along the second direction is a plane, the second surface 20b of the power supply component 20 along the second direction is a plane, and the first surface 10f is in contact with the second surface 20b.

[0173] This helps to make the structures of the functional component 10 and the power component 20 simpler and easier to manufacture.

[0174] In some embodiments, see Figure 8 and Figure 9 The first air pressure hole 10e is located on the first surface 10f, and the third mounting hole is located on 20b. This is conducive to a closer fit between the elastic mounting seat 27 and the first surface 10f, and improves the sealing effect of the communication between the first air pressure hole 10e and the second air pressure hole 27a.

[0175] In some embodiments, the additional oil tank 40 and the nebulizer 30 are detachably connected so that the additional oil tank 40 can be replaced with a new one after the aerosol-generating substrate in the additional storage chamber 40 a is exhausted.

[0176] It can be understood that, when the additional oil tank 40 is separated from the atomizer 30 , the additional storage chamber 40 a is no longer connected to the main storage chamber 30 a .

[0177] There is no limitation on the manner of detachable connection between the atomizer 30 and the additional oil tank 40. For example, see Figure 11 and Figure 12 One of the atomizer 30 and the additional oil tank 40 is provided with an elastic buckle 45, and the other is provided with a disassembly hole 30e. The elastic buckle 45 can be inserted into the disassembly hole 30e and abut against the inner wall of the disassembly hole 30e along a first direction to connect the atomizer 30 and the additional oil tank 40. The elastic buckle 45 is released from the disassembly hole 30e through elastic deformation, thereby separating the atomizer 30 from the additional oil tank 40.

[0178] In some embodiments, see Figure 1 、 Figure 14 、 Figure 20 and Figure 24 The atomizer 30, the additional oil tank 40 and the power supply assembly 20 are detachably connected to each other, and a portion of the outer surface of any one of the three forms a part of the outer contour surface of the aerosol generating device.

[0179] The outer contour surface of the aerosol generating device refers to the surface of the aerosol generating device that can be directly observed by the user with the naked eye when the aerosol generating device is in use.

[0180] During the use of the aerosol generating device, part of the outer surface of any one of the nebulizer 30, the additional oil tank 40 and the power supply assembly 20 can be directly observed by the user, so that when the aerosol generating matrix in the additional storage chamber 40a is exhausted or at least one of the nebulizer 30, the additional oil tank 40 and the power supply assembly 20 is damaged, force can be directly applied to the one of the nebulizer 30, the additional oil tank 40 and the power supply assembly 20 that needs to be disassembled, so as to separate it from the other two and facilitate subsequent separate operation.

[0181] The various embodiments / implementations provided in this application can be combined with each other without causing any contradiction.

[0182] The above are only preferred embodiments of the present application and are not intended to limit the embodiments of the present application. For those skilled in the art, the embodiments of the present application may be modified and varied in various ways. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the embodiments of the present application shall be included in the scope of protection of the embodiments of the present application.
