The term "and/or" used in this specification includes any or all combinations of one or more related listed items.

[0023] In addition, technical features involved in different embodiments of this application described below may be combined together provided that no conflict occurs.

[0024] Referring to FIG. 1 and FIG. 2, an electronic atomization device 1000 includes a housing 10, a power supply assembly 20, a mouthpiece assembly 30, and a plurality of cartridges 40. The plurality of cartridges 40 are arranged in the housing 10. The mouthpiece assembly 30 is connected to the housing 10, and the mouthpiece assembly 30 can be in fluid communication with at least one cartridge 40 in the housing 10.

[0025] For the housing 10, as shown in FIG. 1 and FIG. 2, an accommodation cavity 10a and a first opening 10b in communication with the accommodation cavity 10a are provided on the housing 10. The accommodation cavity 10a may be configured to accommodate the plurality of cartridges 40. The mouthpiece assembly 30 and the housing 10 can cover at least a part of the first opening 10b.

[0026] The housing 10 may include a packaging shell 101, a mounting frame 102, and a connecting end 103. The packaging shell 101 wraps an outer side of the mounting frame 102. A second opening 10c is provided on the packaging shell 101. The second opening 10c is provided opposite to the first opening 10b. The connecting end 103 covers the second opening 10c and is adjacent to an end portion of the packaging shell 101. It may be understood that, a connection manner between the connecting end 103 and the packaging shell 101 includes, but is not limited to, screwing, gluing, magnetic attraction, or the like. Optionally, to ensure airtightness of the accommodation cavity 10a, a sealant or another sealing structure is further arranged at a joint between the connecting end 103 and the packaging shell 101.

[0027] In some embodiments, to make a connection between the connecting end 103 and the packaging shell 101 more stable, a connecting portion 1021 is arranged at an end of the mounting frame 102 close to the connecting end 103. A first snap-in hole 1021a is provided on the connecting portion 1021, and a first hook 1031 is arranged at an end of the connecting end 103 close to the mounting frame 102. When the connecting end 103 is connected to the packaging shell 101, the first hook 1031 is buckled on the first snap-in hole 1021a.

[0028] In some embodiments, the accommodation cavity 10a is at least partially located in the packaging shell 101. The accommodation cavity 10a may be divided to form a first space (not marked) and a second space (not marked). The mounting frame 102 is located in the first space. A mounting cavity 102a is provided on the mounting frame 102. The plurality of cartridges 40 are mounted in the mounting cavity 102a. The second space may be configured for placing at least a part of components of the power supply assembly 20. The second space is located close to the second opening 10c. The connecting end 103 covers the second opening, to ensure airtightness in the second space.

[0029] In some embodiments, referring to FIG. 3 together, the connecting end 103 is further provided with an air inlet hole 1032. External air may enter the second space from the air inlet hole 1032, then at least partially enter the cartridge 40 from the second space, and mix with a volatile formed by heating in the cartridge 40 to form an aerosol. The aerosol flows out of the mouthpiece assembly 30 and is inhaled by a user.

[0030] For the foregoing power supply assembly 20, as shown in FIG. 2 and FIG. 3, the power supply assembly 20 may be arranged in the accommodation cavity 10a. The power supply assembly 20 includes a circuit board 201, a power supply 202, and a plurality of connectors 203. The power supply assembly 20 is configured to output power through the connectors 203. The circuit board 201 is electrically connected to the power supply 202 and the plurality of connectors 203. The connectors 203 may be electrically connected to the cartridge 40, thereby implementing an electrical connection between the cartridge 40 and the power supply assembly 20. Optionally, the plurality of connectors 203 are bonded on the circuit board 201, or the plurality of connectors 203 are bonded on other components of the power supply assembly 20, or the plurality of connectors 203 are located between the cartridges 40 and the circuit board 201. It may be understood that, to output power through the connector 203, a manufacturing material of the connector 203 may be metal or another conductive material, and a specific shape of the connector 203 may not be limited. The connector 203 may be elastic or inelastic, for example, the connector 203 is a conductive spring.

[0031] In some embodiments, the power supply assembly 20 further includes a control switch 204. The control switch 204 is electrically connected to the circuit board 201 or the power supply 202. The control switch 204 is configured to control whether the power supply 202 provides power to the cartridge 40 electrically connected to the power supply 202. It may be understood that, the control switch 204 may be an external switch or an internal switch. The external switch is a switch exposed on a surface of the electronic atomization device. The user may directly contact the external switch to control whether the power supply 202 provides power to the cartridge 40 electrically connected to the power supply 202. The internal switch is a switch hidden inside the electronic atomization device. When the control switch 204 is an internal switch, as shown in FIG. 3, the internal switch may be arranged in the accommodation cavity 10a. The internal switch may be an airflow sensor. The airflow sensor is mounted in a fixed cavity of a fixed block 2041. The fixed block 2041 may be fixed to the connecting end 103. The fixed block 2041 is provided with a third opening 2041b in fluid communication with the second space and the fixed cavity. The connecting end 103 is provided with a vent hole 1033. One side of the airflow sensor is close to the third opening 2041b, and the other side of the airflow sensor is close to the vent hole 1033. When the user inhales through the mouthpiece assembly 30, an airflow in the accommodation cavity 10a flows toward the mouthpiece assembly 30, so that a pressure difference is produced between the side of the airflow sensor close to the third opening 2041b and the side of the airflow sensor close to the vent hole 1033. When the pressure difference between the two sides of the airflow sensor reaches a threshold range, the airflow sensor functions as a switched-on switch, causing the power supply 202 to provide power to the cartridge 40 electrically connected to the power supply 202. When the user does not inhale, the pressure difference between the two sides of the airflow sensor does not reach the threshold range. In this case, the airflow sensor functions as a switched-off switch, causing the power supply 202 to stop providing power to the cartridge 40 electrically connected to the power supply 202.

[0032] In some embodiments, the plurality of connectors 203 include a first connector 2031 and a second connector 2032. The first connector 2031 and the second connector 2032 are respectively configured to connect different electrodes on the cartridge 40, thereby implementing an electrical connection between the cartridge 40 and the power supply assembly 20.

[0033] For the cartridge 40, as shown in FIG. 2 to FIG. 4, a plurality of cartridges 40 are provided, and at least a part of the plurality of cartridges 40 may be cartridges 40 of the same taste or cartridges 40 of different tastes, which may be set by the user based on actual requirements. The plurality of cartridges 40 are mounted in the mounting cavity of the mounting frame 102. The plurality of cartridges 40 may be arranged in a preset direction, for example, the plurality of cartridges 40 are arranged in a straight shape, or the plurality of cartridges 40 are arranged in a rectangle, or the plurality of cartridges 40 are arranged in a triangle, or the like. In the embodiment shown in FIG. 2, a quantity of the plurality of cartridges 40 is two, and the two cartridges 40 are arranged in a straight shape.

[0034] In an embodiment of this application, the cartridge 40 is configured to be translatable between a first position and a second position in the housing 10. The "translatable" means a movement traj ectory of the cartridge 40 is a straight line. The cartridge 40 is configured to abut against a part of the connectors 203 when being translated to the second position, to implement an electrical connection between the cartridge 40 and the power supply assembly 20. The cartridge 40 may be moved in a first direction in the accommodation cavity 10a of the housing 10. It should be noted that, the first direction is a direction from the first opening 10b toward a bottom of the accommodation cavity 10a, or a direction moving from the first position to the second position. The first position may be an initial position of the cartridge 40 accommodated in the accommodation cavity 10a, and the second position may be a stop position after the cartridge 40 slides in the accommodation cavity 10a for a preset distance in the first direction. It is defined that a cartridge 40 located at the first position is a first cartridge 41, and a cartridge 40 located at the second position is a second cartridge 42. Therefore, when the cartridge 40 moves from the first position to the second position, the first cartridge 41 is changed into the second cartridge 42. On the contrary, the second cartridge 42 is changed into the first cartridge 41.

[0035] It may be understood that, in some other embodiments, the first position and the second position may alternatively be re-defined, for example, the first position is defined as a position of the cartridge 40 sliding for a distance d from the initial position in the first direction, and the second position is defined as a position of the cartridge 40 sliding for a distance D from the initial position in the first direction, where D is greater than d, provided that the cartridge 40 at the first position is not connected to the connector 203, and the cartridge 40 at the second position is connected to the connector 203.

[0036] Specifically, the cartridge 40 may include an encapsulation shell 401, a connecting pipe 402, an atomization core 403, and a sealing plug 404. The encapsulation shell 401 is provided with a storage cavity for accommodating a liquid substrate. The sealing plug 404 is configured to seal an end portion of the storage cavity. A liquid storage cotton or another liquid storage substance may be arranged in the storage cavity, so that the liquid substrate is stored by using the liquid storage cotton or the another liquid storage substance. Alternatively, the storage cavity may directly store the liquid substrate without the liquid storage cotton or the another liquid storage substance. The connecting pipe 402 may pass through the storage cavity, the connecting pipe 402 may be provided with an atomization cavity, and the atomization core 403 is arranged in the atomization cavity. The atomization cavity is in communication with the storage cavity, and the liquid substrate in the storage cavity may enter the atomization cavity to be heated by the atomization core 403 to generate an aerosol. The sealing plug 404 may include a first sealing plug 4041 and a second sealing plug 4042. The first sealing plug 4041 is located at an end of the cartridge 40 close to the first opening 10b. The second sealing plug 4042 is located at an end of the cartridge 40 away from the first opening 10b. The storage cavity is provided between the first sealing plug 4041 and the second sealing plug 4042. Two opposite ends of the connecting pipe 402 may be respectively fixed to the first sealing plug 4041 and the second sealing plug 4042. The connecting pipe 402 is in fluid communication with the mouthpiece assembly 30, and the connecting pipe 402 can transfer the aerosol to the mouthpiece assembly 30.

[0037] In some embodiments, the cartridge 40 further includes a first electrode column 405 and a second electrode column 406. Both the first electrode column 405 and the second electrode column 406 may be at least partially located on the second sealing plug 4042, and the first electrode column 405 and the second electrode column 406 may be partially exposed on an outer surface of the second sealing plug 4042. The atomization core 403 includes a heating element and a liquid absorbing element. The liquid absorbing element is configured to guide the liquid substrate in the storage cavity to the heating element. The heating element is configured to heat at least a part of the liquid substrate on the liquid absorbing element, to generate an aerosol for the user to inhale. The heating element may be a resistive heating element, including a first electrode and a second electrode. The first electrode of the heating element is electrically connected to the first electrode column 405, and the second electrode of the heating element is electrically connected to the second electrode column 406. When the cartridge 40 is located at the second position, the first electrode column 405 on the cartridge 40 abuts against the first connector 2031, and the second electrode column 406 on the cartridge 40 abuts against the second connector 2032, thereby implementing an electrical connection between the cartridge 40 and the power supply assembly 20. Optionally, the heating element is a heating wire, a heating mesh, or another component or apparatus that can implement heating, and the liquid absorbing element is a liquid absorbing cotton or another liquid absorbing substance.

[0038] In some embodiments, referring to FIG. 5 together, elastic members 40a are arranged between the power supply assembly 20 and the cartridge 40. At least a part of the elastic members 40a is configured to support the first cartridge 41 to keep the first cartridge 41 at the first position. The elastic member 40a may elastically support the first cartridge 41. One end of the elastic member 40a abuts against the cartridge 40, and the other end of the elastic member 40a may be fixed to the housing 10, or the other end of the elastic member 40a may be bonded on the circuit board 201, or the other end of the elastic member 40a may be bonded at another position. Optionally, the elastic member 40a is a spring. It should be noted that, in other embodiments, one end of the elastic member 40a may be bonded on the cartridge 40, and the other end of the elastic member 40a may be separated from or connected to the power supply assembly 20.

[0039] In some embodiments, a part of the elastic members 40a abuts against the second cartridge 42, and the second cartridge 41 and the power supply assembly 20 may jointly compress the elastic member 40a, so that the elastic member 40a is in an elastically compressed state. In this case, if compression of the second cartridge 40 is canceled, for example, the user removes the mouthpiece assembly 30 from the housing 10, the second cartridge 42 springs to the first position or the initial position under action of elastic force. That is, the second cartridge 42 becomes the first cartridge 41.

[0040] For the foregoing mouthpiece assembly 30, as shown in FIG. 2 and FIG. 4, the mouthpiece assembly 30 is connected to the housing 10 and can compress at least one cartridge 40 in the housing 10, so that at least one cartridge 40 is pushed to the second position by the mouthpiece assembly 30. The mouthpiece assembly 30 further facilitates the user inhaling gas generated in the cartridge 40. The mouthpiece assembly 30 is configured to have a plurality of different connecting directions with the housing 10, to push different cartridges 40 to the second position in the different connecting directions. For example, the mouthpiece assembly 30 may be connected to the housing 10 after being rotated to a preset angle outside or inside the housing 10. The preset angle may be 180 degrees, 60 degrees, 30 degrees, or the like. In some embodiments, the mouthpiece assembly 30 is detachably connected to the housing 10. In this case, the mouthpiece assembly 30 is configured to change a connecting direction with the housing 10 by being detached from the housing 10 and then reconnected to the housing 10.

[0041] Specifically, the mouthpiece assembly 30 includes a shell 301, a mouthpiece 302 with a proximal end open, and a pressing column 303. The mouthpiece 302 and the pressing column 303 are both connected to the shell 301. The mouthpiece 302 is located on one side of the shell 301, and the pressing column 303 is located on the other side of the shell 301. When the mouthpiece assembly 30 is connected to the housing 10, the pressing column 303 abuts against one of the cartridges 40 and pushes the cartridge 40 to translate from the first position to the second position. The cartridge 40 located at the second position is electrically connected to the circuit board 201. The user may inhale at the mouthpiece 302, and in this case, an internal switch (the airflow sensor) on the power supply assembly 20 is in an open state, so that the power supply assembly 20 provides power to the second cartridge 42. Therefore, the second cartridge 42 generates the aerosol for the user to inhale.

[0042] In some embodiments, one end of the pressing column 303 is connected to the mouthpiece 302, and the other end of the pressing column 303 abuts against one of the cartridges 40. An airflow channel 303a is formed in the pressing column 303. The airflow channel 303a is in communication with the proximal end (an aerosol inhalation opening) of the mouthpiece 302, and the airflow channel 303a is in communication with the atomization cavity 401a of the cartridge 40. In this case, gas generated in the atomization cavity of the cartridge 40 may flow to the proximal end of the mouthpiece 302 through the airflow channel 303a, for the user to inhale.

[0043] In some embodiments, one end of the pressing column 303 is embedded into the atomization cavity of the second cartridge 42, and the pressing column 303 is in clearance fit with the second cartridge 42. Through such arrangement, assembly and fit between the mouthpiece assembly 30 and the second cartridge 42 are convenient. One end of the pressing column 303 is embedded into the second cartridge 42, and can limit the mouthpiece 302.

[0044] It may be understood that, the gas generated in the second cartridge 42 is not limited to flow from the pressing column 303 to the mouthpiece 302, that is, the airflow channel 303a is not limited to being located on the pressing column 303. The pressing column 303 may be solid, or may be blocked or closed. The airflow channel 303a may alternatively be located on another component of the mouthpiece assembly 30, provided that the airflow channel 303a is in communication with the mouthpiece 302 and the atomization cavity of the second cartridge 42. For example, the airflow channel 303a is located on the shell 301.

[0045] In some embodiments, the mouthpiece assembly 30 further includes a filling member 304 and a sealing ring 305. The sealing ring 305 provides a sealed connection between the shell 301 and the housing 10. The filling member 304 is arranged in the shell 301, to reduce an air storage space inside the shell 301. When a connection between the airflow channel 303a and the connecting pipe 402 of the second cartridge 42 is an unsealed connection, a small air storage space in the shell 301 can reduce air mixed in the mouthpiece, thereby avoiding thinning taste of the aerosol. This is conducive to improving smoking taste of the user. In addition, when the control switch 204 is the internal switch (the airflow sensor), reducing the internal air storage space can improve sensing accuracy of the airflow sensor. It may be understood that, in this application, a cavity is provided in the shell 301, and the filling member 304 is mounted in the cavity. The filling member 304 may be a sealant or another filler. In some other embodiments, the cavity is not provided in the shell 301, and the shell 301 is a solid structure.

[0046] In some embodiments, when the mouthpiece assembly 30 is connected to the housing 10, a gap between the filling member 304 and the second cartridge 42 is greater than a gap between the filling member 304 and the first cartridge 41.

[0047] In some embodiments, the mouthpiece assembly 30 further includes a limiting member 306. When the mouthpiece assembly 30 is connected to the housing 10, the limiting member 306 abuts against the first cartridge 41, and is configured to limit the first cartridge 41. It should be noted that, the limiting member 306 may be a structure extending from the filling member 304 in the first direction, or the limiting member 306 may be a structure extending from the shell 301 in the first direction. Optionally, the limiting member 306 includes a limiting column 3061. The limiting column 3061 is formed by extending from the shell 301 in the first direction. The limiting column 3061 may be at least partially embedded into the first cartridge 41, to limit the first cartridge 41. The limiting column 3061 may be in a hollow state or a solid state, which may not be specifically limited in this application. Fit between the limiting column 3061 and the first cartridge 41 may be clearance fit or interference fit. When the fit between the limiting column 3061 and the first cartridge 41 is the interference fit, the limiting column 3061 may reduce convection of gas inside and outside the first cartridge 41.

[0048] The limiting member 306 is configured to abut against the first cartridge 41, and the first cartridge 41 is kept at the first position by the elastic member 40a and the limiting member 306. The limiting member 306 can prevent the first cartridge 41 from at least partially being detached from the accommodation cavity 10a when the mouthpiece assembly 30 is detached from the housing 10. The limiting member 306 can block the connecting column 402 of the first cartridge, to keep the connecting column 402 clean. The filling member 304 may be a part included in the limiting member 306.

[0049] In some embodiments, in the first direction, an extended length of the pressing column 303 is greater than an extended length of the limiting member 306, thereby ensuring that the plurality of cartridges 40 form the first cartridge 41 and the second cartridge 42 in the first direction.

[0050] It may be understood that, when a quantity of the cartridges 40 is more than two, because the cartridges 40 may be arranged in a plurality of manners, a plurality of pressing columns 303 and limiting columns 3061 may be arranged on the mouthpiece assembly 30, and the plurality of pressing columns 303 and the limiting columns 3061 are correspondingly arranged according to arrangement positions of the cartridges 40. For example, when the quantity of the cartridges 40 is four, and the cartridges 40 are arranged in a rectangle, a quantity of the pressing columns 303 may be 1, 2, or 3, and a quantity of the limiting columns 3061 may be 0, 1, 2, or 3. When the quantity of the pressing columns 303 is 1, only one cartridge 40 generates the aerosol for the user to inhale. When the quantity of the pressing columns 303 is 2 or 3, the aerosols generated by the plurality of cartridges 40 may be mixed with each other in the mouthpiece assembly 30, to form a gas with a mixed taste for the user to inhale, and in this case, the mouthpiece assembly 30 is in fluid communication with the connecting pipes 402 in the plurality of cartridges 40 at the same time.
