[0051] As used herein, the terms 'upstream' and 'downstream' describe the relative positions of components, or parts of components, in the electronic atomization device in the direction of the flow of the suction airflow.

[0052] like Figure 1-Figure 4As shown, an embodiment of the present application provides an electronic atomization device 10 including a nozzle assembly 100, a first atomization assembly 200, a second atomization assembly 300, and a power supply assembly 400. The electronic atomization device 10 is roughly rectangular. The X direction in the figure represents the width direction of the electronic atomization device 10, the Y direction represents the thickness direction of the electronic atomization device 10, and the Z direction represents the length direction of the electronic atomization device 10. The dimension in the length direction is greater than the dimension in the width direction, and the dimension in the width direction is greater than the dimension in the thickness direction.

[0053] The nozzle assembly 100 and the power supply assembly 400 are detachably connected. After being connected, the nozzle assembly 100 and the power supply assembly 400 together define a housing of the electronic atomization device 10.

[0054] like Figure 5-Figure 6 As shown, the nozzle assembly 100 includes a nozzle piece 101 , a cover body 102 , a sealing piece 103 and a fixing connection piece 104 .

[0055] The suction nozzle part 101 includes a cover plate 101a and a suction nozzle 101b protruding from the cover plate 101a. The cover plate 101a is covered on the cover body 102, and the cover plate 101a defines the top wall of the electronic atomization device 10. A boss 101a1 is provided on the surface of the cover plate 101a facing the cover body 102. The boss 101a1 is hollow inside and has an opening at the lower end. An indicator 101a2 is provided on the surface of the cover plate 101a facing away from the cover body 102. A rotation arrow (not shown in the drawings) is printed on the surface of the indicator 101a2 to indicate the direction in which the suction nozzle part 101 can move relative to the cover body 102. The suction nozzle 101b can be held by the user, and an air outlet channel 101b1 is provided in the suction nozzle 101b.

[0056] The cover body 102 is generally cylindrical in shape, with an upper end of the cover body 102 being closed and a lower end of the cover body 102 being open. The cover body 102 has a cavity therein that is in communication with the lower end opening of the cover body 102 .

[0057] A first air hole 102a, a second air hole 102b, and a connecting hole 102c are provided on the end surface of the upper end of the cover body 102. The first air hole 102a, the second air hole 102b, and the connecting hole 102c are arranged along the width direction of the electronic atomization device 10, and the connecting hole 102c is arranged between the first air hole 102a and the second air hole 102b. The first air hole 102a, the second air hole 102b, and the connecting hole 102c are all connected to the cavity in the cover body 102. The upper end of the connecting hole 102c protrudes from the end surface of the upper end of the cover body 102, and the lower end of the connecting hole 102c extends into the cavity in the cover body 102, thereby forming a convex column (second convex column) extending into the cavity in the cover body 102. Elastic arms 102d are provided on two opposing side walls of the cover 102, extending across the width of the electronic atomizer 10. One end of each elastic arm 102d is connected to the main body of the cover 102, while the other end of each elastic arm 102d is suspended in the air, forming a free end. Elastic arms 102d are provided with a second engaging portion, comprising a snap 102d1 disposed at the free end of each elastic arm 102d. An anti-slip portion 102d2 is also provided on the outer surface of each elastic arm 102d.

[0058] The seal 103 is generally plate-shaped and can be made of silicone. It is positioned on the upper end surface of the cover 102. The seal 103 is provided with holes corresponding to the first air hole 102a, the second air hole 102b, and the connection hole 102c. The holes corresponding to the first air hole 102a or the second air hole 102b on the seal 103 can be embedded in the first air hole 102a or the second air hole 102b; the holes corresponding to the connection hole 102c on the seal 103 can be inserted into the connection hole 102c.

[0059] After assembly, the boss 101a1 is inserted into the connection hole 102c, and the fixed connection member 104, such as a screw, can be fixed in the boss 101a1, and the air outlet channel 101b1 can be selectively connected to one of the first air hole 102a or the second air hole 102b. The boss 101a1 and the fixed connection member 104 can move up and down together in the connection hole 102c, so that the suction nozzle 101 is movably connected to the cover body 102. During use, the user can pinch the suction nozzle 101b and rotate the suction nozzle 101 180°, so that the air outlet channel 101b1 can be selectively connected to the other of the first air hole 102a or the second air hole 102b. The fixed connection member 104 includes an elastic member, such as a spring, which is sleeved on the boss 101a1. It can also be seen from the figure that one end of the air outlet channel 101b1 can abut against the sealing member 103, thereby forming a better airtightness.

[0060] like Figure 7-Figure 8As shown, the power supply assembly 400 includes a third shell 401 , a battery cell 402 , a circuit board 403 , a seal 404 , a cover 405 and a display component 406 .

[0061] The third shell 401 is roughly rectangular in shape, with an opening at its upper end (the third opening) and a closed lower end. The third shell 401 contains a cavity that communicates with the opening at its upper end. A first snap-fit ​​portion is provided on two sidewalls of the third shell 401 that are arranged opposite each other along the width direction of the electronic atomization device 10. The first snap-fit ​​portion includes a snap-fit ​​groove 401a (the first snap-fit ​​groove). The snap-fit ​​groove 401a cooperates with the snap-fit ​​buckle 102d1 to achieve a snap-fit ​​connection between the cover 102 and the third shell 401, that is, to achieve a snap-fit ​​connection between the nozzle assembly 100 and the power supply assembly 400. When disassembling the nozzle assembly 100 from the power supply assembly 400, the user can press the elastic arm 102d with one hand to deform it, thereby releasing the snap-fit ​​between the snap-fit ​​buckle 102d1 and the snap-fit ​​groove 401a and completing the disassembly, i.e., removing the cover 102 from the third shell 401. This operation is relatively simple. The anti-slip portion 102d2 can increase the friction between the user's finger and the elastic arm 102d, making it easier to operate. It is understandable that the first and second clamping portions can be arranged in reverse, that is, the first clamping portion includes a clamping buckle and the second clamping portion includes a clamping groove.

[0062] A partition 401 b is provided in the third shell 401 , and the partition 401 b divides the cavity in the third shell 401 into a first accommodating cavity 401 c , a second accommodating cavity 401 d and a third accommodating cavity 401 e . The first accommodating chamber 401c, the second accommodating chamber 401d and the third accommodating chamber 401e are all connected to the upper opening of the third shell 401. The first accommodating chamber 401c, the second accommodating chamber 401d and the third accommodating chamber 401e are arranged along the width direction of the electronic atomization device 10. The third accommodating chamber 401e is arranged between the first accommodating chamber 401c and the second accommodating chamber 401d. The third accommodating chamber 401e and the first accommodating chamber 401c are separated by a partition 401b. The third accommodating chamber 401e and the second accommodating chamber 401d are also separated by a partition 401b. The partition 401b and the inner wall of the third shell 401 together form the opening of the third accommodating chamber 401e (the second opening). The opening of the third accommodating chamber 401e is inside the third shell 401.

[0063] The first atomizing assembly 200 is at least partially removably installed in the first accommodating chamber 401c, and the second atomizing assembly 300 is at least partially removably installed in the second accommodating chamber 401d.

[0064] The two side walls of the third shell 401 oppositely arranged along the width direction of the electronic atomization device 10 are also provided with steps 401f. When the first atomization assembly 200 or the second atomization assembly 300 is installed into the accommodation cavity, the edge of the first atomization assembly 200 or the second atomization assembly 300 can abut against the steps 401f.

[0065] The bottom wall of the third shell 401 is provided with an air inlet 401g (second air inlet), which is in communication with the third accommodation cavity 401e.

After injection, when the liquid storage medium 2013 reaches saturation, the liquid matrix content in the liquid storage medium 2013 ranges from 0.1 ml to 2 ml, for example, 0.5 ml, 0.8 ml, 1 ml, 1.5 ml, or 2 ml.

[0081] A sealing member 2014 and a sealing member 2015 are also provided within the first housing 2011. The sealing member 2014 or the sealing member 2015 can be made of silicone. The sealing member 2014 is positioned above the liquid storage medium 2013, while the sealing member 2015 is positioned below the liquid storage medium 2013. The space between the sealing member 2014 or the sealing member 2015 and the liquid storage medium 2013 defines an air portion. The sealing member 2014 and the sealing member 2015 seal the liquid storage chamber 2012. The sealing member 2014 has a through hole 2014a communicating with the air outlet 20111a, and the sealing member 2015 has a through hole 2015a communicating with the air inlet 20112a. A liquid absorbing medium 2016 , such as liquid absorbing cotton, is further provided between the sealing member 2014 and the air outlet 20111 a . The liquid absorbing medium 2016 can be accommodated in the accommodating cavity 2014 b of the sealing member 2014 .

[0082] A connecting tube 2017 is also provided within the first housing 2011. The upper end of the connecting tube 2017 passes through the liquid storage chamber 2012 and is connected to the sealing member 2014. The lower end of the connecting tube 2017 is connected to the sealing member 2015. The connecting tube 2017 is preferably made of a thin, rigid material, such as fiberglass or stainless steel. The liquid storage medium 2013 is sleeved onto the connecting tube 2017. Preferably, the inner diameter of the liquid storage medium 2013 is slightly smaller than the outer diameter of the connecting tube 2017, ensuring that the liquid storage medium 2013 is tightly sleeved onto the connecting tube 2017.

[0083] An atomizer core 2018 is also disposed within the first housing 2011. The atomizer core 2018 includes a capillary guide 2018a and a heating element 2018b. The capillary guide 2018a draws liquid from the liquid storage medium 2013 and transfers the liquid to the heating element 2018b. The heating element 2018b is heated by an electric current and transfers heat to the liquid in contact with the heating element 2018b, thereby heating the liquid and generating an aerosol.

[0084] The capillary liquid guide member 2018a is generally tubular in structure. It is understood that in other examples, it can also be a plate-like structure or other regular or irregular shapes. The capillary liquid guide member 2018a can be made of a flexible fiber material, such as cotton fiber, non-woven fabric, or sponge. Alternatively, in other examples, the capillary liquid guide member 2018a can be a rigid porous body, such as porous ceramic or porous glass. The outer surface of the capillary liquid guide member 2018a has a radially outward protrusion.

[0085] The heating element 2018b is positioned adjacent to the inner surface of the capillary guide 2018a, and may be positioned against the inner surface of the capillary guide 2018a, or partially or completely embedded within the capillary guide 2018a. The heating element 2018b may be a resistive heating mesh, a resistive heating coil, or the like. The heating element 2018b may be made of a material with suitable temperature coefficient of resistance (TCR) characteristics, such as 316 stainless steel, titanium, nickel, or a nickel-chromium alloy. In one example, the heating element 2018b may be formed by winding a sheet or mesh-like substrate. The wound heating element 2018b is a non-closed tubular structure in the circumferential direction, i.e., a tubular structure with side openings extending along the length of the first atomizer assembly 200. Leads are welded or otherwise arranged at both ends of the heating element 2018b. The leads may pass through the seal 2014 and be arranged outside the seal 2014, for example, on the surface of the seal 2014 facing the bottom cover 20112.

[0086] The atomizer core 2018 is disposed within the connecting tube 2017. Preferably, the atomizer core 2018 is coaxially disposed with the connecting tube 2017. The connecting tube 2017 also has a liquid guide port on its sidewall. The liquid storage medium 2013 covers the liquid guide port, and a portion of the capillary liquid guide member 2018a is exposed to the liquid storage chamber 2012 through the liquid guide port. This allows the capillary liquid guide member 2018a to be positioned adjacent to or in contact with the liquid storage medium 2013, thereby allowing the liquid matrix in the liquid storage chamber 2012 to flow through the liquid guide port into the atomizer core 2018, where it is drawn in by the capillary liquid guide member 2018a and atomized by the heating element 2018b to generate an inhalable aerosol.

[0087] The sidewall of the connecting tube 2017 is also provided with a notch extending from the lower end of the connecting tube 2017 toward the upper end of the connecting tube 2017. The protruding portion of the capillary guide 2018a extends into the notch, thereby being exposed to the liquid storage chamber 2012. After assembly, the liquid storage medium 2013 maintains contact with a portion of the protruding portion, thereby facilitating the capillary guide 2018a to absorb the liquid matrix.

[0088] The atomizing portion 201 includes a first electrode assembly 2019, which includes a positive electrode 2019a and a negative electrode 2019b spaced apart. The first electrode assembly 2019 preferably utilizes a resilient electrode, such as a cylindrical POGO pin. One end of the first electrode assembly 2019 is exposed on the lower surface of the first housing 2011. The other end of the first electrode assembly 2019 passes through the bottom cover 20112 and maintains contact with the lead of the heating element 2018b, thereby forming an electrical connection.

[0089] The lower surface of the first shell 2011 is further provided with an opening 20112b (first opening). The first shell 2011 further has a boss 20112c extending from the bottom cover 20112 towards the liquid storage cavity 2012. The boss 20112c is hollow inside and communicates with the opening 20112b.

[0090] The first shell 2011 is further provided with a liquid inlet pipe 2020. The upper end of the liquid inlet pipe 2020 is arranged close to the sealing member 2014, and the lower end of the liquid inlet pipe 2020 is sleeved on the boss 20112c. The liquid inlet pipe 2020 and the boss 20112c jointly define a liquid inlet channel that communicates with the opening 20112b. The side wall of the liquid inlet pipe 2020 is provided with a liquid guide opening 2020a that communicates with the liquid storage cavity 2012.

[0091] The liquid inlet channel is provided with a capillary liquid guide 2021. The capillary liquid guide 2021 and the atomization core 2018 are arranged in a direction parallel to the lower surface of the first shell 2011 in the first atomization assembly 200. The cross section of the capillary liquid guide 2021 gradually decreases along the direction from the upper end to the lower end of the capillary liquid guide 2021. The upper end of the capillary liquid guide 2021 is arranged close to the sealing member 2014, and the lower end of the capillary liquid guide 2021 extends towards the opening 20112b. Through the structural layout of the capillary liquid guide 2021 extending from top to bottom to the second liquid storage cavity 2032, cooperating with the use posture of the user, the liquid matrix in the second liquid storage cavity 2032 can overcome gravity and conduct longitudinally from bottom to top, and then conduct laterally to the first liquid storage cavity 2031, effectively controlling the speed of the liquid matrix, avoiding the risk of leakage of the liquid matrix in the first liquid storage cavity 2031 from the air inlet.

[0092] In a preferred implementation, the upper end of the capillary liquid guide 2021 has a flange abutting against the inner wall of the liquid inlet pipe 2020, and the remaining part of the capillary liquid guide 2021 forms a gap with the liquid inlet pipe 2020, which is beneficial to adsorb and retain a small amount of liquid matrix in the gap during liquid conduction, maintain the continuity of liquid supply, and then supplement the liquid when the capillary liquid guide in the first liquid storage cavity 2012 lacks liquid, avoiding the liquid deficiency of the atomization core 2018. The material of the capillary liquid guide 2021 can refer to the part described for the capillary liquid guide 2018a.

[0093] The lower surface of the first shell 2011 is further provided with a clamping hole 20112d.

[0094] The liquid supplementing part 203 includes a second shell 2031 (second shell) independent of the first shell 2011. The second shell 2031 is composed of a main shell 20311 and an upper cover 20312. The main shell 20311 and the upper cover 20312 can be detachably connected by a connecting mechanism, for example, a snap connection.

[0095] Be formed with liquid storage chamber 2032 (second liquid storage chamber) in the second housing 2031, be used to store the second liquid matrix.Similar to the first liquid matrix, the second liquid matrix can be the liquid that comprises the tobacco material that contains volatile tobacco flavor component, can also be the liquid that comprises non-tobacco material.For example, liquid matrix can comprise water, solvent, ethanol, plant extract, spices, flavoring agent or vitamin mixture.Spice can comprise menthol, peppermint, spearmint oil, various fruity fragrance components etc., but is not limited to this.Flavoring agent can comprise the composition that can provide multiple fragrance or local flavor to the user.Vitamin mixture can be for being mixed with at least a material in vitamin A, vitamin B, vitamin C and the vitamin E, but is not limited to this.In addition, the second liquid matrix can comprise the aerosol forming agent as glycerol and propylene glycol.

[0096] It should be noted that the second liquid matrix may have different or identical properties to the first liquid matrix. For example, the second liquid matrix may have different components than the first liquid matrix, or the second liquid matrix may have different concentrations than the first liquid matrix. In some examples, the second liquid matrix and the first liquid matrix have the same composition or type, and the second liquid matrix in the second liquid storage chamber 2032 serves as a liquid replenishment source for the first liquid storage chamber 2012.

[0097] The volume of the liquid storage chamber 2032 is greater than that of the liquid storage chamber 2012. Generally, the volume of the second liquid matrix stored in the liquid storage chamber 2032 is between 2 ml and 10 ml, such as 4 ml, 5 ml, 6 ml, 8 ml, etc.

[0098] A sealing member 2033 is provided in the second housing 2031. The sealing member 2033 is made of silicone material and is provided between the main housing 20311 and the upper cover 20312, thereby sealing the liquid storage chamber 2032.

[0099] The upper surface of the second housing 2031 has a protruding connecting portion 20312a, and the connecting portion 20312a is provided with a liquid outlet 20312b that communicates with the liquid storage chamber 2032. A sealing member 2034 is sleeved on the connecting portion 20312a.

[0100] A snap-fit ​​buckle 20312c is further provided on the upper surface of the second housing 2031. The snap-fit ​​buckle 20312c and the snap-fit ​​hole 20112d form a first connection mechanism, thereby connecting the second housing 2031 to the first housing 2011. The second housing 2031 and the first housing 2011 can be connected in a non-detachable or detachable manner.

[0101] When the second housing 2031 is connected to the first housing 2011, the connecting portion 20312a extends into the liquid inlet channel through the opening 20112b. The lower end of the capillary liquid guide 2021 is inserted into the second housing 2031 through the liquid outlet 20312b. The sealing member 2033 is located between the boss 20112c and the connecting portion 20312a. In this way, the second liquid matrix stored in the liquid storage chamber 2032 can flow through the liquid outlet 20312b to the liquid inlet channel and then to the liquid storage chamber 2012, thereby replenishing the liquid storage chamber 2012. The sealing member 2033 prevents leakage of the liquid matrix in the liquid inlet channel. The capillary liquid guide 2021 effectively guides the second liquid matrix stored in the liquid storage chamber 2032 to the liquid storage chamber 2012. It is understandable that the connecting portion 20312a does not extend into the liquid inlet channel, and it is also feasible that the liquid outlet 20312b is aligned and connected with the opening 20112b.

[0102] When the second housing 2031 is connected to the first housing 2011, the air inlet 20112a and the first electrode assembly 2019 are not blocked by the second housing 2031. In other words, the second housing 2031 avoids the air inlet 20112a and the first electrode assembly 2019. The second housing 2031 is connected to the lower surface (first outer surface) of the first housing 2011, or the second housing 2031 is connected to a portion of the lower surface of the first housing 2011. The air inlet 20112a is provided on the first portion G of the lower surface of the first housing 2011, and one end of the first electrode assembly 2019 is also exposed on the first portion G of the lower surface of the first housing 2011. The second housing 2031 blocks the second portion F of the lower surface of the first housing 2011 and avoids the first portion G of the lower surface of the first housing 2011, thereby exposing the air inlet 20112a and the first electrode assembly 2019 to the first portion G of the lower surface of the first housing 2011.

[0103] It is understood that before the second housing 2031 is connected to the first housing 2011, the opening 20112b, the liquid outlet 20312b, and the air outlet 20111a can be sealed with a sealing member to prevent leakage of the liquid matrix and facilitate product transportation. The sealing member can be made of silicone. After receiving the atomization unit 201 and the liquid replenishment unit 203, the user can remove the sealing member and then assemble the device.

[0104] It should be noted that, in combination with the above-mentioned specific structure of the first atomizer assembly 200, those skilled in the art can understand the second atomizer assembly 300 with the same structural design. It is understandable that the liquid matrix in the first atomizer assembly 200 and the liquid matrix in the second atomizer assembly 300 can be different or the same.

[0105] When the first atomization assembly 200 is installed into the first accommodating cavity 401c, the second shell 2031 of the first atomization assembly 200 is completely accommodated in the third shell 401, and the first shell 2011 of the first atomization assembly 200 is at least partially exposed outside the third shell 401. The at least partially exposed first shell 2011 outside the third shell 401 facilitates the user to pinch and remove the first atomization assembly 200 from the first accommodating cavity 401c. In order to facilitate the user to view the remaining amount of liquid substrate in the liquid storage cavity 2032, the third shell 401 corresponding to the first accommodating cavity 401c is provided with a visible window. The visible window can be formed of transparent material on the third shell 401, or can be an opening on the third shell 401. It can be understood that when the second atomization assembly 300 is installed into the second accommodating cavity 401d, the above-mentioned characteristics also exist, which will not be repeated here.

[0106] In a preferred implementation, when the first atomization assembly 200 is installed into the first accommodating cavity 401c, the second shell 2031 of the first atomization assembly 200 is at least partially located in the first accommodating cavity 401c, and the first shell 2011 of the first atomization assembly 200 can be partially accommodated between the spacing portion E and the upper end opening of the third shell 401, and partially exposed outside the third shell 401. When the second atomization assembly 300 is installed into the second accommodating cavity 401d, the above-mentioned characteristics also exist, which will not be repeated here.

[0107] When the first atomization assembly 200 is installed into the first accommodating cavity 401c, the first electrode assembly 2019 of the first atomization assembly 200 and the third electrode assembly 4034 one-to-one correspondingly maintain contact to form an electrical connection. When the second atomization assembly 300 is installed into the second accommodating cavity 401d, the electrode assembly of the second atomization assembly 300 and the second electrode assembly 4031 one-to-one correspondingly maintain contact to form an electrical connection.

[0108] When the first atomizer assembly 200 is installed in the first accommodating chamber 401c and the second atomizer assembly 300 is installed in the second accommodating chamber 401d, the first portion of the first outer surface of the first shell 2011 of the first atomizer assembly 200 and the first portion of the first outer surface of the shell of the atomizing portion of the second atomizer assembly 300 both abut against the cover 405, that is, abut against the partition E. Because the rehydration portions and the first electrode assembly of the first atomizer assembly 200 and the second atomizer assembly 300 are disposed on the same side surface, that is, the first outer surface, this helps save space within the power supply assembly and reduces the volume of the entire electronic atomizer device. In addition, during installation, the liquid replenishing parts of the first atomizing assembly 200 and the second atomizing assembly 300 are correspondingly accommodated in the first accommodating cavity 401c and the second accommodating cavity 401d, and the first part of the first outer surface is docked with the spacer E. The proximal surface of the third electrode assembly provided in the spacer E is significantly higher than the bottom of the first accommodating cavity 401c and the second accommodating cavity 401d, thereby effectively preventing the liquid matrix in the atomizing part of the first atomizing assembly 200 and the second atomizing assembly 300 from leaking to the circuit board on the spacer E. In this way, the first part G of the lower surface of the first shell 2011 in the first atomizer assembly 200 can block the second air flow cavity 4044 to form a closed chamber, so that the air inlet 20112a of the first atomizer assembly 200 is connected to the second air flow cavity 4044, and the airflow in the second air flow cavity 4044 can flow into the first atomizer assembly 200 through the air inlet 20112a of the first atomizer assembly 200, mix with the aerosol generated by the heating element 2018b, and then flow out from the air outlet 20111a of the first atomizer assembly 200. Correspondingly, the first part of the lower surface of the shell of the atomizing part in the second atomizing assembly 300 can block the first airflow cavity 4043 to form a closed chamber, so that the air inlet of the second atomizing assembly 300 is connected to the first airflow cavity 4043, and the airflow in the first airflow cavity 4043 can flow into the second atomizing assembly 300 through the air inlet of the second atomizing assembly 300, and after mixing with the aerosol generated by the heating element in the second atomizing assembly 300, flow out from the air outlet of the second atomizing assembly 300.

[0109] When the nozzle assembly 100 is connected to the power supply assembly 400, the cover 102 is connected to the third housing 401 and closes the openings of the accommodating chambers (the first accommodating chamber 401c and the second accommodating chamber 401d). The portion of the first housing 2011 exposed outside the first accommodating chamber 401c and the portion of the second atomizer assembly 300 exposed outside the second accommodating chamber 401d are both accommodated in the cavity within the cover 102.

[0110] When the first atomizer assembly 200 is installed in the first accommodating chamber 401c and the second atomizer assembly 300 is installed in the second accommodating chamber 401d, the notched groove 20111b of the first atomizer assembly 200 and the notched groove of the second atomizer assembly 300 enclose a snap-fit ​​groove A (a second snap-fit ​​groove). When the nozzle assembly 100 is connected to the power supply assembly 400, the protrusion formed by the lower end of the connection hole 102c extending into the cavity within the cover body 102 can snap into the snap-fit ​​groove A, thereby effectively maintaining or supporting the first atomizer assembly 200 and the second atomizer assembly 300, ensuring electrical connection between the electrode assemblies.

[0111] When the mouthpiece assembly 100 is connected to the power supply assembly 400, the air outlet 20111a of the first atomizer assembly 200 is aligned and connected to the first air hole 102a, and the air outlet of the second atomizer assembly 300 is aligned and connected to the second air hole 102b, so that the aerosol generated by the first atomizer assembly 200 or the second atomizer assembly 300 can be inhaled by the user through the air outlet channel 101b1. In a further embodiment, when the cover body 102 is snap-connected to the third shell 401, the seal 103 can elastically abut the first atomizer assembly 200 and the second atomizer assembly 300, thereby retaining the first atomizer assembly 200 and the second atomizer assembly 300 in the corresponding accommodating chamber and providing a seal around the air outlet 20111a of the first atomizer assembly 200 and the air outlet of the second atomizer assembly 300.

[0112] It should be noted that the preferred embodiments of the present application are given in the specification and drawings of this application. However, the present application can be implemented in many different forms and is not limited to the embodiments described in this specification. These embodiments are not intended to be additional limitations on the content of this application.

In addition, the above-mentioned technical features can be combined with each other to form various embodiments not listed above, which are all considered to be within the scope of the description of this application; further, it is obvious to those skilled in the art that improvements or changes can be made based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this application.
