It can be understood that: the connection method between the connection end 103 and the packaging shell 101 includes but is not limited to screw connection, gluing, magnetic attraction, etc. Optionally, in order to ensure the airtightness of the accommodating cavity 10a, a sealant or other sealing structure is also provided at the connection between the connection end 103 and the packaging shell 101.

[0032] In some embodiments, in order to make the connection between the above-mentioned connecting end 103 and the packaging shell 101 more stable, a connecting portion 1021 is provided at one end of the mounting frame 102 close to the connecting end 103, and a first snap-in 1021a is provided on the connecting portion 1021, and a first hook 1031 is provided at one 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 snapped into the first snap-in 1021a.

[0033] In some embodiments, at least part of the accommodating cavity 10a is located in the packaging shell 101. The accommodating cavity 10a can be divided into a first space (not marked) and a second space (not marked), the mounting frame 102 is located in the first space, the mounting frame 102 is provided with an installation cavity 102a, a plurality of cigarette cartridges 40 are installed in the installation cavity 102a, the second space can be used to place at least part of the components of the power supply assembly 20, the second space is located near the second opening 10c, and the connecting end 103 is covered on the second opening to ensure the airtightness in the second space.

[0034] In some embodiments, please refer to Figure 3 An air inlet hole 1032 is also provided on the connecting end 103, and external air can enter the second space through the air inlet hole 1032, and then at least partially enter the above-mentioned cigarette cartridge 40 from the second space, and mix with the volatile substances formed by heating in the cigarette cartridge 40 to form an aerosol, and the aerosol flows out from the nozzle assembly 30 and is inhaled by the user.

[0035] For the above power supply component 20, Figure 2 and Figure 3 As shown, the power supply assembly 20 can be arranged in the accommodating cavity 10a, and 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 connector 203. The circuit board 201 is electrically connected to the power supply 202 and the plurality of connectors 203. The connector 203 can be electrically connected to the cigarette cartridge 40, thereby realizing the electrical connection between the cigarette cartridge 40 and the power supply assembly 20. Optionally, a plurality of connectors 203 are combined on the circuit board 201, or a plurality of connectors 203 are combined on other components in the power supply assembly 20, or a plurality of connectors 203 are located between the cigarette cartridge 40 and the circuit board 201. It can be understood that: in order to realize the output of power through the connector 203, the manufacturing material of the connector 203 can be metal or other conductive materials, and the specific shape of the connector 203 can be not limited, and the connector 203 can be elastic or inelastic, for example: the connector 203 is a conductive spring.

[0036] In some embodiments, the power supply assembly 20 further includes a control switch 204, which is electrically connected to the circuit board 201 or the power supply 202, and is used to control whether the power supply 202 provides power to the cigarette cartridge 40 electrically connected thereto. It is understandable that the control switch 204 can be an external switch or an internal switch. The external switch is a switch exposed on the surface of the electronic atomization device, and the user can control whether the power supply 202 provides power to the cigarette cartridge 40 electrically connected thereto by directly contacting the external switch; the internal switch is a switch hidden inside the electronic atomization device. When the control switch 204 is an internal switch, such as Figure 3As shown, the internal switch can be arranged in the accommodating cavity 10a, and the internal switch can be an airflow sensing sensor, which is installed in the fixed cavity of the fixing block 2041, and the fixing block 2041 can be fixed on the connecting end 103, and the fixing block 2041 is provided with a third opening 2041b for fluidly connecting the second space and the fixed cavity, and the connecting end 103 is provided with a vent 1033, one side of the airflow sensing sensor is close to the third opening 2041b, and the other side of the airflow sensing sensor is close to the vent 1033. When the user sucks through the nozzle assembly 30, the accommodating cavity 10a is provided with a third opening 2041b for fluidly connecting the second space and the fixed cavity, and the connecting end 103 is provided with a vent 1033. The airflow in the cavity 10a flows toward the nozzle assembly 30, thereby generating a pressure difference between the side of the airflow sensing sensor close to the third opening 2041b and the side close to the vent 1033. When the pressure difference on both sides of the airflow sensing sensor reaches a threshold range, the airflow sensing sensor acts as a switch on, so that the power supply 202 provides power to the cigarette cartridge 40 electrically connected thereto; when the user does not inhale, the pressure difference on both sides of the airflow sensing sensor does not reach the threshold range. At this time, the airflow sensing sensor acts as a switch off, so that the power supply 202 stops providing power to the cigarette cartridge 40 electrically connected thereto.

[0037] In some embodiments, the plurality of connectors 203 include a first connector 2031 and a second connector 2032 , and the first connector 2031 and the second connector 2032 are respectively used to connect different electrodes on the cigarette cartridge 40 , thereby achieving electrical connection between the cigarette cartridge 40 and the power supply assembly 20 .

[0038] For the above-mentioned cigarette cartridge 40, if Figure 2-Figure 4 As shown, there are multiple cartridges 40, and at least some of the multiple cartridges 40 can be cartridges 40 of the same flavor or different flavors. Users can set it according to actual needs. Multiple cartridges 40 are installed in the mounting cavity of the mounting frame 102. Multiple cartridges 40 can be arranged along a preset direction, for example: multiple cartridges 40 are arranged in a straight line, or multiple cartridges 40 are arranged in a rectangle, or multiple cartridges 40 are arranged in a triangle, etc. Figure 2 In the illustrated embodiment, the number of the plurality of cigarette cartridges 40 is two, and the two cigarette cartridges 40 are arranged in a straight line.

[0039] In one embodiment of the present application, the cigarette cartridge 40 is configured to be able to translate between a first position and a second position in the housing 10. The so-called translation means that the moving trajectory of the cigarette cartridge 40 is a straight line. The cigarette cartridge 40 is configured to abut against part of the connecting member 203 when translated to the second position, so as to achieve electrical connection between the cigarette cartridge 40 and the power supply assembly 20. The cigarette cartridge 40 can move along the first direction in the accommodating chamber 10a of the housing 10. It should be noted that the above-mentioned first direction refers to the direction from the first opening 10b toward the bottom of the accommodating chamber 10a, or the direction of movement from the first position to the second position. The above-mentioned first position can be the initial position when the cigarette cartridge 40 is accommodated in the accommodating chamber 10a, and the above-mentioned second position can be the stop position of the cigarette cartridge 40 after sliding a preset distance in the first direction in the accommodating chamber 10a. The cigarette cartridge 40 located at the first position is defined as the first cigarette cartridge 41, and the cigarette cartridge 40 located at the second position is defined as the second cigarette cartridge 42, so that when the cigarette cartridge 40 moves from the first position to the second position, it changes from the first cigarette cartridge 41 to the second cigarette cartridge 42, and vice versa.

[0040] It can be understood that: in some other embodiments, the first position and the second position can also be redefined, for example: the first position is defined as the position where the cartridge 40 slides a distance d from the initial position along the first direction, and the second position is defined as the position where the cartridge 40 slides a distance D from the initial position along the first direction, where D is greater than d, and as long as the cartridge 40 at the first position is not connected to the connector 203, the cartridge 40 at the second position can be connected to the connector 203.

[0041] Specifically, the cigarette cartridge 40 may include a packaging shell 401, a connecting pipe 402, an atomizing core 403 and a sealing plug 404. The packaging shell 401 is provided with a storage cavity for accommodating a liquid matrix. The sealing plug 404 is used to seal the end of the storage cavity. Liquid storage cotton or other liquid storage materials may be provided in the storage cavity to store the liquid matrix, or the storage cavity may directly store the liquid matrix without liquid storage cotton or other liquid storage materials. The connecting pipe 402 may pass through the storage cavity. An atomizing cavity may be provided in the connecting pipe 402. The atomizing core 403 is provided in the atomizing cavity. The atomizing cavity is connected to the storage cavity. The liquid matrix in the storage cavity can enter the atomizing cavity for the atomizing core 403 to heat and generate an aerosol. The sealing plug 404 may include a first sealing plug 4041 and a second sealing plug 4042, wherein the first sealing plug 4041 is located at one end of the cartridge 40 close to the first opening 10b, and the second sealing plug 4042 is located at one end of the cartridge 40 away from the first opening 10b, the storage chamber is arranged between the first sealing plug 4041 and the second sealing plug 4042, and the opposite ends of the connecting pipe 402 may be fixed on the first sealing plug 4041 and the second sealing plug 4042, respectively. 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. Optionally, the atomization chamber of the second cartridge 42 is in fluid communication with the mouthpiece assembly 30, and at least a portion of the pressing column 303 is embedded in the first sealing plugs 4041404.

[0042] In some embodiments, the cigarette cartridge 40 also includes a first electrode column 405 and a second electrode column 406, at least parts of the first electrode column 405 and the second electrode column 406 can be located on the second sealing plug 4042, and parts of the first electrode column 405 and the second electrode column 406 can be exposed on the outer surface of the second sealing plug 4042, the atomization core 403 includes a heating element and a liquid absorption element, the liquid absorption element is used to guide the liquid matrix in the storage chamber to the heating element, the heating element is used to heat at least part of the liquid matrix on the liquid absorption element to produce an aerosol for the user to inhale, the heating element can be a resistive heating element, including a first electrode and a second second electrode, the first electrode of the heating element is electrically connected to the above-mentioned first electrode column 405, and the second electrode of the heating element is electrically connected to the above-mentioned second electrode column 406, when the cigarette cartridge 40 is in the second position, the first electrode column 405 thereon abuts against the first connecting member 2031, and the second electrode column 406 thereon abuts against the second connecting member 2032, thereby realizing the electrical connection between the cigarette cartridge 40 and the power supply assembly 20. Optionally, the heating element is a heating wire, a heating net or other components or devices that can achieve heating, and the liquid absorbing element is liquid absorbing cotton or other liquid absorbing materials.

[0043] In some embodiments, please refer to Figure 5An elastic member 40a is provided between the power supply assembly 20 and the cigarette cartridge 40. At least part of the elastic member 40a is configured to support the first cigarette cartridge 41 to keep the first cigarette cartridge 41 in the first position. The elastic member 40a can play a role of elastic support for the first cigarette cartridge 41. One end of the elastic member 40a abuts against the cigarette cartridge 40, and the other end of the elastic member 40a can be fixed on the housing 10. Alternatively, the other end of the elastic member 40a can be combined with the circuit board 201, or the other end of the elastic member 40a can be combined with other positions. Optionally, the elastic member 40a is a spring. It should be noted that in other embodiments, one end of the elastic member 40a can be combined with the cigarette cartridge 40, and the other end can be separated from or connected to the power supply assembly 20.

[0044] In some embodiments, part of the elastic member 40a abuts against the second cigarette cartridge 42, and the second cigarette cartridge 41 and the power supply assembly 20 can jointly squeeze the elastic member 40a, so that the elastic member 40a is in an elastic compression state. At this time, if the suppression of the second cigarette cartridge 40 is released, for example, the user removes the mouthpiece assembly 30 from the housing 10, the second cigarette cartridge 42 will rebound to the first position or the initial position under the action of the elastic force, that is, the second cigarette cartridge 42 becomes the first cigarette cartridge 41.

[0045] For the above-mentioned nozzle assembly 30, as Figure 2 and Figure 4 As shown, the nozzle assembly 30 is connected to the housing 10 and can suppress at least one cigarette cartridge 40 inside the housing 10, so that at least one cigarette cartridge 40 is pushed to the second position by the nozzle assembly 30. The nozzle assembly 30 also facilitates the user to inhale the gas generated in the cigarette cartridge 40. The nozzle assembly 30 is configured to have a plurality of different connection directions with the housing 10, so as to push different cigarette cartridges 40 to the second position through different connection directions. For example, the nozzle assembly 30 can be rotated outside or inside the housing 10 to a preset angle and then connected to the housing 10. The preset angle can be 180 degrees, 60 degrees, 30 degrees, etc. In some embodiments, the nozzle assembly 30 is detachably connected to the housing 10. At this time, the nozzle assembly 30 is configured to change the connection direction between it and the housing 10 by disconnecting it from the housing 10 and then connecting it.

[0046] Specifically, the suction nozzle assembly 30 includes a shell 301, a suction nozzle 302 with an open proximal end, and a pressing column 303. The suction nozzle 302 and the pressing column 303 are both connected to the shell 301. The suction nozzle 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 suction nozzle assembly 30 is connected to the shell 10, the pressing column 303 abuts against one of the cigarette cartridges 40 and pushes the cigarette cartridge 40 to move from the first position to the second position. The cigarette cartridge 40 located at the second position is electrically connected to the circuit board 201. The user can inhale the suction nozzle 302. At this time, the internal switch (airflow sensing sensor) on the power supply assembly 20 is in an open state, so that the power supply assembly 20 provides power to the second cigarette cartridge 42. The second cigarette cartridge 42 therefore generates an aerosol for the user to inhale.

[0047] In some embodiments, one end of the pressing column 303 is connected to the suction nozzle 302, and the other end abuts against one of the cigarette cartridges 40, and an air flow channel 303a is formed in the pressing column 303, the air flow channel 303a is connected to the proximal end (inhalation port) of the suction nozzle 302, and the air flow channel 303a is connected to the atomization chamber 401a of the cigarette cartridge 40. At this time, the gas generated in the atomization chamber of the cigarette cartridge 40 can flow to the proximal end of the suction nozzle 302 through the air flow channel 303a for the user to inhale.

[0048] In some embodiments, one end of the pressing column 303 is embedded in the atomization chamber of the second cigarette cartridge 42, and the pressing column 303 and the second cigarette cartridge 42 are gap-matched, so that the assembly and matching between the nozzle assembly 30 and the second cigarette cartridge 42 are convenient. One end of the pressing column 303 is embedded in the second cigarette cartridge 42, which can limit the position of the nozzle 302.

[0049] It can be understood that the gas generated in the second cigarette cartridge 42 is not limited to flowing from the pressing column 303 to the suction nozzle 302, that is, the air flow channel 303a is not limited to being located on the pressing column 303. The pressing column 303 can be solid, or can be blocked or closed. The air flow channel 303a can also be located on other components in the suction nozzle assembly 30, as long as the air flow channel 303a is connected with the suction nozzle 302 and the atomization chamber of the second cigarette cartridge 42. For example, the air flow channel 303a is located on the shell 301.

[0050] In some embodiments, the above-mentioned suction nozzle assembly 30 also includes a filling piece 304 and a sealing ring 305, the sealing ring 305 provides a sealed connection between the shell 301 and the housing 10, and the filling piece 304 is arranged inside the shell 301 to reduce the gas storage space inside the shell 301. When the connection between the airflow channel 303a and the connecting pipe 402 in the second cigarette cartridge 42 is non-sealed, the smaller gas storage space inside the shell 301 can reduce the mixing of air into the suction nozzle, thereby diluting the taste of the aerosol, so it helps to improve the taste of the user's suction. In addition, when the control switch 204 is an internal switch (airflow sensing sensor), reducing the internal gas storage space can improve the sensing accuracy of the airflow sensing sensor. It can be understood that: in the present application, a cavity is provided inside the shell 301, and the above-mentioned filling piece 304 is installed in the cavity. The filling piece 304 can be a sealant or other filler. In some other embodiments, no cavity is provided inside the shell 301, and the shell 301 is a solid structure.

[0051] In some embodiments, when the nozzle assembly 30 is connected to the housing 10 , the interval between the filling piece 304 and the second cigarette cartridge 42 is greater than the interval between the filling piece 304 and the first cigarette cartridge 41 .

[0052] In some embodiments, the above-mentioned suction nozzle assembly 30 further includes a limiting member 306. When the suction nozzle assembly 30 is connected to the housing 10, the limiting member 306 abuts against the first cigarette cartridge 41 to limit the first cigarette cartridge 41. It should be noted that the above-mentioned limiting member 306 can be a structure extending from the filling member 304 along the first direction, and the limiting member 306 can also be a structure extending from the housing 301 along the first direction. Optionally, the limiting member 306 includes a limiting column 3061, which is obtained by extending from the housing 301 along the first direction, and at least a part of the limiting column 3061 can be embedded in the first cigarette cartridge 41, so as to limit the first cigarette cartridge 41. The limiting column 3061 can be in a hollow state or a solid state, which is not specifically limited in this application. The fit between the limiting column 3061 and the first cigarette cartridge 41 may be a clearance fit or an interference fit. When the fit between the limiting column 3061 and the first cigarette cartridge 41 is an interference fit, the limiting column 3061 may reduce gas convection inside and outside the first cigarette cartridge 41 .

[0053] The stopper 306 is used to abut against the first cigarette cartridge 41, and the first cigarette cartridge 41 is kept in the first position under the action of the elastic member 40a and the stopper 306. The stopper 306 can prevent at least a part of the first cigarette cartridge 41 from being separated from the accommodating chamber 10a when the suction nozzle assembly 30 is separated from the housing 10. The stopper 306 can cover the connecting pipe 402 of the first cigarette cartridge to keep the connecting pipe 402 clean. The filling member 304 can be a component of the stopper 306.

[0054] In some embodiments, along the first direction, the extension length of the pressing column 303 is greater than the extension length of the limiting member 306, thereby ensuring that the plurality of cigarette cartridges 40 form a first cigarette cartridge 41 and a second cigarette cartridge 42 along the first direction.

[0055] It can be understood that: when the number of cigarette cartridges 40 exceeds two, since there are many situations for the arrangement of the cigarette cartridges 40, at this time, the number of pressing columns 303 and limiting columns 3061 on the suction nozzle assembly 30 may also be multiple, and the multiple pressing columns 303 and limiting columns 3061 are arranged corresponding to the arrangement positions of the cigarette cartridges 40. For example: when the number of cigarette cartridges 40 is four and the cigarette cartridges 40 are arranged in a rectangular arrangement, the number of pressing columns 303 may be 1, 2 or 3, and the number of limiting columns 3061 may be 0, 1, 2 or 3. When the number of pressing columns 303 is 1, only one cigarette cartridge 40 generates aerosol for the user to inhale. When the number of pressing columns 303 is 2 or 3, the aerosols generated by multiple cigarette cartridges 40 can be mixed with each other in the suction nozzle assembly 30 to form a mixed-flavor gas for the user to inhale, and at this time, the suction nozzle assembly 30 is simultaneously connected to the connecting pipe 402 fluid in the multiple cigarette cartridges 40.
