An electronic atomization device

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to a Chinese patent application filed with the Patent Office of China on March 1, 2024, with application number 202420409545.7 and entitled “AN ELECTRONIC ATOMIZATION DEVICE”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The embodiments of the present application relate to the field of electronic atomization technology, and in particular to an electronic atomization device. Background Art

[0004] An electronic atomization device is a device that can vaporize a liquid matrix to produce an aerosol. Existing electronic atomization devices contain multiple atomizers, each of which can generate aerosol independently. During use, only one of the atomizers is in a working state and electrically connected to the power supply assembly, while the other atomizers are in a non-working state. In order to achieve the switching of multiple atomizers, the multiple atomizers are usually rotated as a whole relative to the power supply assembly at the same time, thereby switching the atomizer electrically connected to the power supply assembly. However, during the rotation process, it is easy to wear the electrodes of the atomizer or the electrodes of the power supply assembly, so that after one or more rotations, the atomizer cannot form a reliable electrical connection with the power supply assembly.

[0049] Unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the relevant listed items.

[0050] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0051] Referring to Figures 1 and 2, the electronic atomization device 100 includes a housing 1, a power supply assembly 2, multiple cigarette cartridges 3, a pressing block 4, and a cover plate 5. The multiple cigarette cartridges 3 are housed within the housing 1 and are movable within the housing 1. At least a portion of the power supply assembly 2 may also be housed within the housing 1, but the present invention is not limited thereto. When a cigarette cartridge 3 meets appropriate conditions, the power supply assembly 2 can supply power to the cigarette cartridge 3 that meets the conditions, causing the cigarette cartridge 3 to generate aerosol. At least a portion of the pressing block 4 and at least a portion of the cover plate 5 are housed within the housing 1.

[0052] Referring to Figures 1 to 4 , a first receiving space 11 and a second receiving space 12 are provided within the housing 1. The housing 1 having the first receiving space 11 and the second receiving space 12 can be integrally formed or assembled. Multiple cigarette cartridges 3 are accommodated in the first receiving space 11, while at least a portion of the pressing block 4 and at least a portion of the cover plate 5 are accommodated in the second receiving space 12.

[0053] Specifically, the pressing block 4 only occupies a part of the second receiving space 12, and the pressing block 4 can be removed from the second receiving space 12. When the pressing block 4 is received in a position of the second receiving space 12, it corresponds to at least one cigarette cartridge 3 and can push the corresponding cigarette cartridge 3 from the first position to the second position. When the cigarette cartridge 3 is located in the second position, it can be electrically connected to the power supply component 2, and the power supply component 2 can provide power to the cigarette cartridge 3 electrically connected to it based on the operation switch or other trigger conditions.

[0054] The cover plate 5 occupies another part of the second receiving space 12, and when the cover plate 5 is received in the second receiving space 12, the cover plate 5 corresponds to the remaining at least one cigarette cartridge 3. After the pressing block 4 is removed from the second receiving space 12, an unoccupied idle space will appear in the second receiving space 12, wherein the cover plate 5 is configured to be movable in the second receiving space 12 having an idle space, and the position of the idle space in the second receiving space 12 is changed by moving the cover plate 5, and then the pressing block 4 is assembled in the second receiving space 12 to occupy the idle space whose position has been changed, thereby changing the position of the pressing block 4 to be received in the second receiving space 12 again, so that the pressing block 4 corresponds to the remaining at least one cigarette cartridge 3, so that the pressing block 4 can abut against the remaining at least one cigarette cartridge 3, so that the cigarette cartridge 3 moves from the first position to the second position along the first direction, and then the cigarette cartridge 3 is electrically connected to the power supply component 2. In the process of making the cigarette cartridge 3 that was not previously electrically connected to the power supply assembly 2 electrically connected to the power supply assembly 2, there is no need to make multiple cigarette cartridges 3 and the power supply assembly 2 rotate relative to each other, thereby reducing the wear of the cigarette cartridge 3 on the power supply assembly 2.

[0055] In one example, referring to Figures 2, 4, and 5, the pressing block 4 includes a main body 41 and a pressing portion 42. The main body 41 is generally plate-shaped. The main body 41 removably occupies a portion of the second receiving space 12 of the housing 1, and the main body 41 and the cover 5 can jointly occupy the second receiving space 12, so that the main body 41 and the cover 5 can jointly cover the first receiving space 11. The pressing portion 42 is provided on a surface of the main body 41. The pressing portion 42 is configured to abut against the cigarette cartridge 3 corresponding to the pressing block 4 and press the cigarette cartridge 3 from the first position to the second position when the main body 41 is connected to the housing 1 and occupies a portion of the second receiving space 12, thereby electrically connecting the cigarette cartridge 3 to the power supply assembly 2, and the power supply assembly 2 can supply power to the cigarette cartridge 3.

[0056] In one example, the pressing block 4 further includes a suction nozzle 43, and the suction nozzle 43 and the pressing portion 42 are respectively arranged on opposite sides of the main body 41, and the suction nozzle 43 is connected to the airway in the cigarette cartridge 3 in the second position, so that the user can inhale the aerosol generated by the cigarette cartridge 3 into the mouth by sucking the suction nozzle 43.

[0057] Furthermore, the suction nozzle 43 is connected to the cigarette cartridge 3 at the second position through the pressing portion 42 .

[0058] Specifically, the pressing block 4 is provided with an air outlet channel 47 which sequentially passes through the pressing portion 42, the main body 41 and the suction nozzle 43. When the main body 41 is installed to the shell 1 and occupies a part of the second receiving space 12, the end of the pressing portion 42 away from the suction nozzle 43 is inserted into the air channel 36 of a cigarette cartridge 3 and presses the cigarette cartridge 3 to the second position. At this time, the suction nozzle 43 is connected with the air channel 36 of the cigarette cartridge 3 at the second position through the air outlet channel 47, and the user can inhale the smoke generated by the cigarette cartridge 3 at the second position through the suction nozzle 43.

[0059] In one example, referring to Figures 2, 4, and 6, the cigarette cartridge 3 includes a liquid storage chamber 31 and an upper seal 32 that seals the end of the liquid storage chamber 31. At least part of the airway 36 of the cigarette cartridge 3 is formed in the upper seal 32. At least a portion of the pressing portion 42 can be embedded in the airway 36 defined by the upper seal 32 and abut the upper seal 32, so that the air outlet channel 47 can communicate with the liquid storage chamber 31, thereby allowing the smoke generated by the aerosol-generating matrix in the liquid storage chamber 31 to enter the user's mouth through the air outlet channel 47. Specifically, when the pressing portion 42 is embedded in the airway 36 defined by the upper seal 32 and abuts the upper seal 32, the upper seal 32 can seal the gap between the pressing portion 42 and the cigarette cartridge 3 in the second position to prevent smoke from leaking from the gap between the pressing portion 42 and the cigarette cartridge 3.

[0060] In one example, referring to Figures 2 and 4, the power supply assembly 2 includes a plurality of elastic members 21, and the plurality of elastic members 21 are respectively arranged corresponding to the plurality of cartridges 3. The elastic members 21 are configured to support the cartridges 3, thereby keeping the cartridges 3 that do not correspond to the pressing block 4 in the first position, and keeping the cartridges 3 corresponding to the pressing block 4 against the pressing block 4, so that the cartridges 3 corresponding to the pressing block 4 are kept in the second position.

[0061] Furthermore, an elastic member 21 is provided corresponding to one cigarette cartridge 3, and multiple elastic members 21 are all located at one end of the cigarette cartridge 3 away from the cover plate 5 or the pressing block 4, so that the cigarette cartridge 3 abutting the pressing block 4 is maintained in the second position, and the other cigarette cartridges 3 are maintained in the first position, thereby keeping the airway 36 of the cigarette cartridge 3 corresponding to the pressing block 4 connected to the partial air outlet channel 47 defined by the pressing portion 42.

[0062] In one example, referring to FIG. 2 and FIG. 4 , the elastic member 21 is configured to deform in a direction parallel to the first direction X, so that the elastic member 21 can drive the cigarette cartridge 3 to move from the second position to the first position.

[0063] Specifically, when the main body 41 of the pressing block 4 is installed on the shell 1, under the pressure of the pressing portion 42, the cigarette cartridge 3 can break through the elastic force of the elastic member 21 and move from the first position to the second position, and under the elastic force of the elastic member 21, the cigarette cartridge 3 can remain against the pressing portion 42; when the pressing block 4 is removed, under the action of the elastic member 21, the cigarette cartridge 3 can return from the second position to the first position along the first direction X.

[0064] In one example, the power supply assembly 2 further includes a circuit board 22, which is mounted within the housing 1. The elastic member 21 is disposed between the circuit board 22 and the corresponding cigarette cartridge 3. Specifically, one end of the elastic member 21 abuts the circuit board 22, and the other end abuts the cigarette cartridge 3, so that the elastic member 21 can generate an elastic force on the cigarette cartridge 3. When the cigarette cartridge 3 is in the second position, the cigarette cartridge 3 abuts the circuit board 22, allowing the power supply assembly 2 to supply power to the cigarette cartridge 3 via the circuit board 22. When the cigarette cartridge 3 is in the first position, the cigarette cartridge 3 is separated from the circuit board 22.

[0065] It is worth noting that the maximum elastic force of the elastic member 21 is smaller than the minimum force required to remove the pressing block 4 , thereby preventing the elastic member 21 from directly ejecting the pressing block 4 from the housing 1 .

[0066] Furthermore, the power supply assembly 2 also includes a battery 23, which is installed in the shell 1 and is located on the side of the circuit board 22 away from the cigarette cartridge 3. The battery 23 is electrically connected to the circuit board 22 so that the battery 23 can power the cigarette cartridge 3 in the second position through the circuit board 22.

[0067] In one example, referring to Figures 2, 4, and 6, the cigarette cartridge 3 includes a liquid storage chamber 31 and an upper seal 32 that seals the end of the liquid storage chamber 31. At least part of the airway 36 of the cigarette cartridge 3 is formed in the upper seal 32. The cover plate 5 includes a blocking portion 51. At least a portion of the upper seal 32 protrudes from the first surface 33 of the cigarette cartridge 3. The blocking portion 51 elastically abuts against the portion of the upper seal 32 in the cigarette cartridge 3 corresponding to the cover plate 5 that protrudes from the first surface 33, thereby blocking the airway 36 of the cigarette cartridge 3 corresponding to the cover plate 5, which helps reduce the risk of leakage of the aerosol matrix in the cigarette cartridge 3 in the first position.

[0068] In one example, the number of cover plates 5 can be one or more, and the size of the space occupied by a single cover plate 5 in the second receiving space 12 is substantially equal to the size of the space occupied by the main body 41 of a single pressing block 4 in the second receiving space 12. In this arrangement, after the pressing block 4 is removed from the second receiving space 12 so that the above-mentioned unoccupied idle space appears in the second receiving space 12, a cover plate 5 can be moved into the idle space, so that the position of the idle space is changed, and then the main body 41 of the pressing block 4 is installed in the idle space after the position is changed (i.e., the space where the cover plate 5 was before it was moved). In this way, the switching of the cigarette cartridges 3 can be realized, which is very convenient.

[0069] In one example, referring to Figures 2 and 4, the number of cover plates 5 can be one or more, the pressing block 4 and one or more cover plates 5 are arranged in the second receiving space 12 along the second direction, and the cover plate 5 and the pressing block 4 abut against each other in the second direction Y, thereby reducing the risk of the pressing block 4 or the cover plate 5 moving along the second direction Y in the second receiving space 12.

[0070] Furthermore, the pressing block 4 corresponds to a cigarette cartridge 3, and each cover plate 5 corresponds to a cigarette cartridge 3. When the pressing block 4 is installed in the second receiving space 12, the cigarette cartridge 3 corresponding to the pressing block 4 is pressed to the second position by the pressing block 4, and the cigarette cartridge 3 corresponding to the cover plate 5 is maintained in the first position under the action of the elastic member 21.

[0071] It is understandable that when there are multiple cover plates 5, the pressing block 4 and the multiple cover plates 5 may not be arranged along the second direction Y. Specifically, the pressing block 4 and the multiple cover plates 5 may also be arranged in a ring shape or in a rectangular array. It is only necessary that after the pressing block 4 is removed from the second receiving space 12, at least one cover plate 5 can be moved to the position where the pressing block 4 was before being removed, and the pressing block 4 can be installed to the position where the cover plate 5 was before being moved. A detailed description is not provided here.

[0072] In one example, referring to Figures 4 and 11, the first receiving space 11 includes a plurality of independent slide grooves 111 distributed along the second direction, and a cigarette cartridge 3 is slidably mounted in a slide groove 111. A plurality of cover plates 5 and pressing blocks 4 are sequentially arranged in the second direction Y in the second receiving space 12, and the cover plates 5 and pressing blocks 4 abut against each other in the second direction Y, so that the cover plates 5 and pressing blocks 4 can completely cover the first receiving space 11, preventing the cover plates 5 and pressing blocks 4 from moving in the second direction Y during use.

[0073] In one example, referring to Figures 4 and 11, the housing 1 further includes a slide 13 extending along the second direction Y, and at least a portion of the pressing block 4 is removably mounted in the slide 13. The cover plate 5 is slidably connected to the slide 13 so that when the pressing block 4 is removed from the housing 1, the cover plate 5 can slide along the slide 13 to the position where the pressing block 4 was before being removed, and then the pressing block 4 is mounted to the position where the cover plate 5 was before sliding, thereby achieving the position interchange of the cover plate 5 and the pressing block 4, thereby achieving the switching of the cigarette cartridge 3. In this embodiment, by providing the slide 13, the cover plate 5 can slide along the slide 13. When switching the cigarette cartridge 3, the cover plate 5 can be moved only after the pressing block 4 is removed from the housing 1, without having to remove the cover plate 5 from the housing 1. This is very convenient, and there is no need to rotate all the cigarette cartridges 3 relative to the power supply assembly 2 to switch the cigarette cartridge 3 electrically connected to the power supply assembly 2. This can reduce the wear on the power supply assembly 2 during the rotation process, which is conducive to ensuring that the cigarette cartridge 3 can still form a reliable electrical connection with the power supply assembly 2 after long-term use.

[0074] In one example, referring to FIG. 14 , the pressing block 4 is snap-connected to the slideway 13 to prevent the pressing block 4 from falling off from the housing 1 without human intervention.

[0075] In one example, referring to Figures 13 and 14, there are two slideways 13, which are respectively arranged on opposite sides of the pressure block 4. The pressure block 4 includes a first snap-fit ​​portion 44 and a second snap-fit ​​portion 45 that are respectively snap-fitted to the two slideways 13. The elasticity of the first snap-fit ​​portion 44 is greater than that of the second snap-fit ​​portion 45. Thus, when the pressure block 4 is installed in the housing 1, the second snap-fit ​​portion 45 can be first obliquely inserted into one of the slideways 13, and then the first snap-fit ​​portion 44 can be snapped into the other slideway 13. When removing the pressure block 4 from the housing 1, a force F as shown in Figure 13 can be applied to the suction nozzle 43. Since the elasticity of the first snap-fit ​​portion 44 is greater than that of the second snap-fit ​​portion 45, the first snap-fit ​​portion 44 is deformed under the action of the force F and gradually leaves the slideway 13, thereby allowing the pressure block 4 to be removed from the housing 1.

[0076] In one example, referring to Figures 10 and 11 , the slide 13 includes a first limiting wall 131 and a second limiting wall 132 disposed opposite each other, and the cover plate 5 includes a slider 52. At least a portion of the slider 52 is located between the first limiting wall 131 and the second limiting wall 132, and along the first direction X, the distance between the first limiting wall 131 and the second limiting wall 132 is greater than the thickness of the slider 52, so that the slider 52 can slide along the slide 13. Furthermore, referring to Figure 15 , the second limiting wall 132 has a notch 1321. The pressure block 4 includes a locking portion 46. At least a portion of the locking portion 46 is snap-fitted to the first limiting wall 131, and the locking portion 46 is restrained by the first limiting wall 131 in the notch 1321. This prevents the pressure block 4 from sliding along the slide 13. Furthermore, the first limiting wall 131 restrains the locking portion 46, preventing the pressure block 4 from leaving the second receiving space 12 without external force.

[0077] In one example, referring to Figures 11, 13, and 14, there are two slideways 13, each of which includes a first limiting wall 131 and a second limiting wall 132 disposed opposite each other. Both second limiting walls 132 are provided with a notch 1321. The pressure block 4 includes a first latch portion 44 and a second latch portion 45 disposed opposite each other. When the pressure block 4 is mounted on the housing, the first latch portion 44 is engaged with the notch 1321 of one of the slideways 13, and the second latch portion 45 is engaged with the notch 1321 of the other slideway 13. In this embodiment, by engaging the first latch portion 44 with the notch 1321 of one of the slideways 13 and the second latch portion 45 with the notch 1321 of the other slideway 13, the risk of the pressure block 4 detaching from the housing 1 without manual intervention can be reduced.

[0078] Further, referring to Figures 4 and 11, the second limiting wall 132 is provided with a plurality of notches 1321 along the second direction Y, and the number of the notches 1321 is the same as the number of the cigarette cartridges 3. The plurality of notches 1321 corresponds one-to-one to the plurality of cigarette cartridges 3, so that when the engaging portion 46 is engaged with any notch 1321, the pressing portion 42 of the pressing block 4 can press the cigarette cartridge 3 corresponding to the notch 1321 to slide from the first position to the second position.

[0079] In one example, referring to Figures 2, 6 and 14, there are two slides 13, and the cover plate 5 includes two opposing sliders 52, wherein at least a portion of one slider 52 is slidably connected to one of the slides 13, and at least a portion of the other slider 52 is slidably connected to the other slide 13.

[0080] In one example, referring to Figures 2 and 4, an air inlet channel 14 is formed in the housing 1, and the air inlet channel 14 is connected to the air channel 36 of at least one cigarette cartridge 3. The electronic atomization device 100 also includes a pneumatic switch 6, which is disposed in the housing 1 and is connected to a circuit board 22. The pneumatic switch 6 is configured to detect the airflow in the air inlet channel 14 and, based on the detection result, control the circuit board 22 to supply power to the cigarette cartridge 3 in the second position. For example, the pneumatic switch 6 can control the circuit board 22 based on detecting whether there is airflow in the air inlet channel 14. Specifically, when the pneumatic switch 6 detects that there is airflow in the air inlet channel 14, the pneumatic switch 6 controls the circuit board 22 to supply power to the cigarette cartridge 3 in the second position; when the pneumatic switch 6 detects that there is no airflow in the air inlet channel 14, the pneumatic switch 6 controls the circuit board 22 to stop supplying power to the cigarette cartridge 3 in the second position. In this embodiment, by setting a pneumatic switch 6, when the user draws on the mouthpiece 43, an airflow is formed in the air inlet channel 14, and the pneumatic switch 6 controls the circuit board 22 to supply power to the cigarette cartridge 3 in the second position, thereby avoiding the circuit board 22 continuously supplying power to the cigarette cartridge 3 and wasting the aerosol generating matrix in the cigarette cartridge 3.

[0081] In one example, referring to Figures 2 and 13, a plurality of connectors 221 are provided on the circuit board 22, with each two connectors 221 corresponding to one cigarette cartridge 3. The cigarette cartridge 3 is also provided with two power connection portions 34. When the cigarette cartridge 3 is in the second position, the two power connection portions 34 respectively abut the two connectors 221, so that an electrical connection is formed between the cigarette cartridge 3 and the circuit board 22, and the power supply assembly 2 provides power to the cigarette cartridge 3 through the connectors 221. When the cigarette cartridge 3 is in the first position, the cigarette cartridge 3 in the first position is separated from the connectors 221. It is worth noting that the connector 221 has a deformable ability, and when the cigarette cartridge 3 is in the second position, the connector 221 is deformed under the pressure of the cigarette cartridge 3, so that the connector 221 remains abutting against the power connection portion 34 of the cigarette cartridge 3.

[0082] In order to enable readers to better understand the technical solution of the present application, the following is an example of four cigarette cartridges 3 to illustrate the process of switching cigarette cartridges in the electronic atomization device 100 in the present application, wherein the four cigarette cartridges 3 are spaced apart along the second direction Y, and viewed from the perspective of the electronic atomization device 100 shown in Figure 4, the four cigarette cartridges 3 are, from left to right, the first cigarette cartridge 3a, the second cigarette cartridge 3b, the third cigarette cartridge 3c, and the fourth cigarette cartridge 3d. Correspondingly, the first receiving space 11 includes four relatively independent chutes 111, and the four cigarette cartridges 3 are respectively slidably arranged in the four chutes 111, so that the four cigarette cartridges 3 can move between the first position and the second position along the corresponding chutes 111. There are three cover plates 5, which are, from left to right, the first cover plate 5a, the second cover plate 5b, and the third cover plate 5c. The three cover plates 5 and the pressing block 4 are respectively against a cigarette cartridge 3. Initially, the pressing block 4 abuts against the first cigarette cartridge 3a, so that the first cigarette cartridge 3a moves to the second position along the corresponding slide groove 111 and abuts the power supply component 2, and the power supply component 2 supplies power to the first cigarette cartridge 3a. At this time, the second cigarette cartridge 3b, the third cigarette cartridge 3c and the fourth cigarette cartridge 3d are all in the first position in the first direction X, and the first cover plate 5a covers the slide groove 111 where the second cigarette cartridge 3b is located, the second cover plate 5b covers the slide groove 111 where the third cigarette cartridge 3c is located, and the third cover plate 5c covers the slide groove 111 where the fourth cigarette cartridge 3d is located. When the first cigarette cartridge 3a is consumed, the process of switching the cigarette cartridge 3 is as follows: Step 01: As shown in Figure 7, the pressing block 4 is removed from the second receiving space 12. At this time, the first cigarette cartridge 3a returns to the first position along the corresponding slide groove 111; Step 02: As shown in Figure 8, the first cover plate 5a covering the slide groove 111 where the second cigarette cartridge 3b is located is moved in the second receiving space 12 to the position covering the slide groove 111 where the first cigarette cartridge 3a is located; Step 03: As shown in Figure 9, the pressing block 4 is installed in the second receiving space 12, so that the pressing block 4 covers the slide groove 111 where the second cigarette cartridge 3b is located, and under the action of the pressing block 4, the second cigarette cartridge 3b moves from the first position to the second position along the first direction X, and the second cigarette cartridge 3b abuts against the power supply component 2, and the power supply component 2 supplies power to the second cigarette cartridge 3b. When the second cigarette cartridge 3b is consumed, step 01 is repeated; the second cover plate 5b is then moved to a position covering the chute 111 where the second cigarette cartridge 3b is located; finally, the pressing block 4 is installed in the second receiving space 12, so that the pressing block 4 covers the chute 111 where the third cigarette cartridge 3c is located. Under the action of the pressing block 4, the third cigarette cartridge 3c moves from the first position to the second position along the first direction X, and the power supply assembly 2 supplies power to the third cigarette cartridge 3c. When the third cigarette cartridge 3c is consumed, step 01 is repeated; the third cover plate 5c is then moved to a position covering the chute 111 where the third cigarette cartridge 3c is located; finally, the pressing block 4 is installed in the second receiving space 12, so that the pressing block 4 covers the chute 111 where the fourth cigarette cartridge 3d is located. Under the action of the pressing block 4, the fourth cigarette cartridge 3d moves from the first position to the second position along the first direction X, and the power supply assembly 2 supplies power to the fourth cigarette cartridge 3d.In this embodiment, the cigarette cartridge 3 can be switched by simply exchanging the positions of the pressing block 4 and any one of the cover plates 5 , which is very convenient.

[0083] When the aerosol matrix in the cigarette cartridge 3 is about to be consumed or has been consumed, if you continue to inhale, it is easy to produce smoke with a burnt smell, which affects the user's smoking experience. Therefore, a plurality of statistical circuits (not shown) can also be provided on the circuit board 22, one statistical circuit corresponding to one cigarette cartridge 3, when the cigarette cartridge 3 is in the second position, the statistical circuit corresponding to the cigarette cartridge 3 counts the duration of the connector 221 abutting the cigarette cartridge 3 to provide power to the cigarette cartridge 3, and when the duration is greater than the first duration, the statistical circuit controls the alarm device (not shown) in the power supply assembly 2 to alarm, thereby reminding the user to switch the cigarette cartridge 3. In this embodiment, the statistical circuit counts the duration of the power supply assembly 2 to the cigarette cartridge 3 in the second position, thereby reminding the user to switch the cigarette cartridge 3 in time, thereby reducing the risk of the user inhaling burnt smoke, which is conducive to improving the user experience.

[0084] In some embodiments, the statistical circuit can also count the number of times the corresponding connector 221 provides power to the cigarette cartridge 3. When the number is greater than a first value, the statistical circuit controls the alarm device in the power supply component 2 to sound an alarm, thereby reminding the user to switch the cigarette cartridge 3.

[0085] In one example, referring to Figures 2 and 4 , the electronic atomization device 100 further includes a support member 7 , which is mounted within the housing 1 and positioned between the battery 23 and the cartridge 3 . The support member 7 is provided with a plurality of bosses 71 at intervals, each corresponding one-to-one to each of the cartridges 3 . Each of the bosses 71 passes through the circuit board 22 and is at least partially inserted into the air passage 36 of the cartridge 3 . An elastic member 21 is sleeved around the portion of a boss 71 that protrudes from the circuit board 22 . The support member 7 is further provided with a plurality of through holes 711 extending through the bosses 71 . The through holes 711 constitute part of the air inlet passage 14 and are in communication with the air passage 36 of the corresponding cartridge 3 .

[0086] In one example, referring to FIG4 , the cigarette cartridge 3 further includes a lower seal 35 , which is opposite to the upper seal 32 and defines at least a portion of the airway 36 of the cigarette cartridge 3 , and at least a portion of the boss 71 is inserted into the lower seal 35 , and the lower seal 35 is used to seal the gap between the cigarette cartridge 3 and the boss 71 .

[0087] In one example, referring to Figures 2 and 4 , the electronic atomization device 100 further includes a housing cover 8 , which covers the end of the housing 1 away from the second receiving space 12 . The housing cover 8 is provided with an air inlet hole 81 that at least partially constitutes the air inlet passage 14 . The air inlet hole 81 is used to allow external air to enter the air inlet passage 14 . The pneumatic switch 6 is mounted on the surface of the housing cover 8 facing the housing 1 .

[0088] In an embodiment of the present application, a first receiving space 11 and a second receiving space 12 are provided in the shell 1, and multiple cigarette cartridges 3 are accommodated in the first receiving space 11. The pressing block 4 can removably occupy only a part of the second receiving space 12, and when the pressing block 4 is at least partially received in the second receiving space 12, the pressing block 4 corresponds to at least one cigarette cartridge 3 and abuts against the corresponding cigarette cartridge 3, so that the cigarette cartridge 3 moves from the first position to the second position along the first direction. When the cigarette cartridge 3 is in the second position, it is electrically connected to the power supply assembly 2, and the cover plate 5 occupies another part of the second receiving space 12 and corresponds to the remaining at least one cigarette cartridge 3. After the pressing block 4 is removed from the second receiving space 12, the cover plate 5 can be moved in the second receiving space 12 to change the position of the pressing block 4 in the second receiving space 12 again by moving the cover plate 5, so that the pressing block 4 corresponds to the remaining at least one cigarette cartridge 3, so that the remaining at least one cigarette cartridge 3 replaces the original cigarette cartridge 3 and is electrically connected to the power supply assembly 2. There is no need to rotate multiple cigarette cartridges 3 relative to the power supply assembly 2 to switch the cigarette cartridges 3 electrically connected to the power supply assembly 2, which can reduce the wear caused by rotation, so that the cigarette cartridges 3 can still form a reliable electrical connection with the power supply assembly 2 after long-term use.
