[0002] This section is intended to provide a background or context for the embodiments of the present application. No description herein is admitted to be prior art by virtue of its inclusion in this section.

[0003] The nebulizer includes a liquid storage chamber, which is used to store the liquid aerosol-generating matrix. In the related art, liquid storage cotton is used to lock the liquid to prevent the liquid aerosol-generating matrix from leaking out of the liquid storage chamber. However, the liquid aerosol-generating matrix in the liquid storage cotton is often not fully utilized, resulting in waste of the liquid aerosol-generating matrix and low utilization rate. The nebulizer without liquid storage cotton is affected by changes in the external environment (such as temperature changes), and the pressure in the liquid storage chamber changes greatly, which can easily lead to leakage of the liquid storage chamber. Utility Model Content

[0004] In view of this, the embodiments of the present application hope to provide an atomizer and an electronic atomization device that can improve the air pressure stability of the liquid storage chamber and reduce the probability of liquid leakage in the liquid storage chamber.

[0008] A heating component is used to atomize the liquid aerosol-generating matrix from the liquid storage chamber into an aerosol.

[0009] In some embodiments, the two flexible members are spaced apart along the first direction, and the circumferential surfaces of the two flexible members surrounding the first direction abut against the cavity wall of the installation cavity, and the space between the two flexible members of the installation cavity is the liquid storage cavity.

[0010] In some embodiments, the flexible member includes a connecting edge and a flexible membrane, the connecting edge surrounds the outer circumference of the flexible membrane, the connecting edge abuts the cavity wall of the installation cavity, and a portion of the flexible membrane protrudes toward a side away from the liquid storage cavity to form a first pressure stabilizing groove.

[0011] In some embodiments, the area enclosed by the first pressure-stabilizing groove is a boss, and a portion of the boss protrudes toward a side away from the liquid storage chamber to form a second pressure-stabilizing groove.

[0012] In some embodiments, the housing assembly includes a suction nozzle, an inner shell, and a base body, wherein the suction nozzle and the base body are respectively connected to two ends of the inner shell along the first direction to jointly define the installation cavity.

[0013] In some embodiments, the flexible part includes a first flexible part, which is arranged on the side of the suction nozzle close to the installation cavity, and a first pressure-stabilizing cavity is formed between the first flexible part and the suction nozzle. The suction nozzle is formed with an atmospheric connecting hole, and the atmospheric connecting hole connects the first pressure-stabilizing cavity and the outside atmosphere.

[0014] In some embodiments, the shell assembly includes a limiting portion, the limiting portion is sealed with a circumferential surface surrounding the first direction and a cavity wall surface of the liquid storage cavity, and the flexible member includes a second flexible member, and the second flexible member is clamped between the limiting portion and the seat body.

[0018] The atomizer provided in the embodiment of the present application defines a liquid storage chamber by means of a flexible member and the wall surface of the mounting chamber, so that the volume of the liquid storage chamber is variable. On the one hand, when the pressure of the gas in the liquid storage chamber changes due to changes in the external environment, the elastic deformation characteristics of the flexible member are utilized to change the volume of the liquid storage chamber to maintain the air pressure in the liquid storage chamber stable, thereby improving the air pressure stability of the liquid storage chamber, thereby avoiding leakage caused by excessive changes in the air pressure of the liquid storage chamber to a certain extent, and reducing the probability of leakage in the liquid storage chamber. On the other hand, there is no need to use the liquid storage cotton in the related art to lock the liquid aerosol generating matrix.

[0044] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0045] The various specific technical features and embodiments described in the specific embodiments can be combined in any appropriate manner, unless there is any contradiction. For example, different specific technical features / embodiments can be combined to form different embodiments. To avoid unnecessary repetition, the various possible combinations of the specific technical features / embodiments in this application will not be described separately. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance. The application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0046] In related art, to address the problem of liquid leakage in liquid storage chambers, especially those with large capacities (e.g., 16 ml or more), a liquid reservoir is typically placed inside the chamber, using its adsorption properties to lock in the liquid aerosol-forming substrate. This, on the one hand, occupies space in the chamber, reducing the amount of liquid aerosol-forming substrate that can be stored. On the other hand, the liquid aerosol-forming substrate in the reservoir cannot be fully utilized, resulting in waste.

[0047] See also Figures 1 to 4An embodiment of the present application provides an atomizer 100, including a shell assembly 10, a flexible member 20 and a heating assembly 30. The shell assembly 10 forms a mounting cavity 10a, the flexible member 20 is arranged in the mounting cavity 10a, and the flexible member 20 abuts against the cavity wall of the mounting cavity 10a to jointly define a liquid storage cavity 10b. The heating assembly 30 is used to atomize the liquid aerosol-generating matrix from the liquid storage cavity 10b into an aerosol.

[0048] Liquid aerosol-generating substrate refers to the liquid fluid used for atomization to generate aerosol.

[0049] The liquid storage chamber 10b is used to store the liquid aerosol-generating substrate. The liquid aerosol-generating substrate can be delivered to the heating component 30, which is used to heat the liquid aerosol-generating substrate, thereby atomizing it to form an aerosol for the user to inhale. For example, please refer to Figure 4 The heating component 30 is located on the side of the flexible member 20 away from the liquid storage chamber 10b. In this way, the heating component 30 does not occupy the space in the liquid storage chamber 10b, and the liquid storage chamber 10b can store more liquid aerosol generating matrix.

[0050] The flexible member 20 may be a structure made of a flexible material. Flexible material refers to a material that can produce elastic deformation such as bendable, foldable, twistable, compressible and / or stretchable.

[0051] The flexible member 20 and the wall surface of the mounting cavity 10a together define the liquid storage cavity 10b. That is, the wall surface of the liquid storage cavity 10b can be formed by the flexible member 20 and the housing assembly 10. Since the flexible member 20 can undergo elastic deformation, the volume of the liquid storage cavity 10b can be variable. In this way, on the one hand, when the pressure of the gas (e.g., air) in the liquid storage cavity 10b changes due to changes in the external environment, the elastic deformation characteristics of the flexible member 20 are utilized to change the volume of the liquid storage cavity 10b to maintain the stability of the air pressure in the liquid storage cavity 10b, thereby to a certain extent avoiding excessive changes in the air pressure in the liquid storage cavity 10b and causing leakage. On the other hand, there is no need to use the liquid storage cotton in the related art to lock the liquid aerosol generating matrix. The liquid storage cotton can be omitted in the liquid storage cavity 10b. The liquid storage cavity 10b can store more liquid aerosol generating matrix and fully utilize it to generate more aerosol, increasing the number of puffs of aerosol inhaled by the user, improving the user experience, and reducing waste.

[0052] The specific material of the flexible member 20 is not limited. For example, the flexible member 20 can be made of silicone material.

[0053] The atomizer 100 provided in the embodiment of the present application defines a liquid storage chamber 10b by means of a flexible member 20 and the wall surface of the mounting chamber 10a, so that the volume of the liquid storage chamber 10b is variable. On the one hand, when the pressure of the gas in the liquid storage chamber 10b changes due to changes in the external environment, the elastic deformation characteristics of the flexible member 20 are utilized to change the volume of the liquid storage chamber 10b to maintain the air pressure in the liquid storage chamber 10b stable, thereby improving the air pressure stability of the liquid storage chamber 10b. This, to a certain extent, avoids leakage caused by excessive changes in the air pressure of the liquid storage chamber 10b and reduces the probability of leakage in the liquid storage chamber 10b. On the other hand, there is no need to use liquid storage cotton as in the related art to lock the liquid aerosol generating matrix. The liquid storage chamber 10b can store more liquid aerosol generating matrix and fully utilize it to generate more aerosol, thereby increasing the number of puffs of aerosol inhaled by the user, improving the user experience, and reducing waste.

[0054] In one embodiment, the flexible member 20 is an integrally formed structure. For example, the flexible member 20 can be an integrally formed structure formed by injection molding, compression molding, or other processes.

[0055] For some examples, see Figures 2 to 4 The two flexible members 20 are spaced apart along the first direction, and the circumferential surfaces of the two flexible members 20 surrounding the first direction abut against the cavity wall surface of the mounting cavity 10a. The space between the two flexible members 20 of the mounting cavity 10a is the liquid storage cavity 10b. The circumferential surface refers to the side wall surface of the flexible member surrounding the axial direction with the first direction as the axial direction. In other words, the two flexible members 20 and the cavity wall surface of the mounting cavity 10a between the two flexible members 20 jointly define the liquid storage cavity 10b, which makes more effective use of the space. In addition, the use of two flexible members 20 can produce greater deformation when the air pressure fluctuates, so it is easier to maintain the air pressure stability in the liquid storage cavity 10b, improve the pressure stabilization performance of the liquid storage cavity 10b, and effectively prevent the liquid storage cavity 10b from leaking.

[0056] For some examples, see Figure 5 The flexible member 20 includes a connecting edge 21 and a flexible membrane 22. The connecting edge 21 surrounds the outer periphery of the flexible membrane 22, and the connecting edge 21 abuts the cavity wall of the installation cavity 10a. A portion of the flexible membrane 22 protrudes toward the side away from the liquid storage cavity 10b to form a first pressure-stabilizing groove 22a. In this way, the first pressure-stabilizing groove 22a can increase the area of ​​the flexible membrane 22 to enhance the elastic deformation performance of the flexible member 20, thereby improving the pressure-stabilizing performance of the liquid storage cavity 10b. In addition, the first pressure-stabilizing groove 22a can also increase the volume of the liquid storage cavity 10b, so that the liquid storage cavity 10b can store more liquid aerosol-generating matrix, increase the number of aerosol puffs that the user can inhale, and improve the user experience.

[0057] The connecting edge 21 can increase the contact area between the flexible member 20 and the cavity wall of the installation cavity 10 a , thereby enhancing the connection stability between the flexible member 20 and the housing assembly 10 .

[0058] The flexible member 20 seals against the wall of the mounting cavity 10a. In one embodiment, see Figure 5 The connecting edge 21 is formed with a plurality of flanges 211, which are pressed against the circumferential surface of the mounting cavity 10a. In this way, the plurality of flanges 211 play a multi-layer sealing role, improving the sealing performance of the liquid storage cavity 10b.

[0059] For example, see Figure 6 and Figure 7 , multiple flanges 211 are arranged at intervals along the first direction to facilitate production and assembly.

[0060] It should be noted that, in this application, a plurality refers to a number including two and more than two.

[0061] For some examples, see Figure 5 The area enclosed by the first pressure-stabilizing groove 22a forms a boss 22b. A portion of the boss 22b protrudes toward the side away from the liquid storage chamber 10b to form a second pressure-stabilizing groove 22c. The second pressure-stabilizing groove 22c further enhances the deformation properties of the flexible member 20 and increases the volume of the liquid storage chamber 10b. The boss 22b can reduce or even offset the effects of external forces on the flexible membrane 22, such as the gravity of the liquid aerosol-generating substrate, preventing excessive deformation of the flexible member 20 caused by external forces.

[0062] For example, see Figure 3 and Figure 4 When the atomizer 100 is in an upright position, the first direction can be consistent with the up-down direction, that is, the two flexible members 20 are spaced apart in the up-down direction. The gravity of the liquid aerosol generating matrix is ​​applied to the lower flexible member 20, and the boss 22b protrudes upward compared to the first pressure-stabilizing groove 22a. The boss 22b can reduce or even offset the influence of the gravity of the liquid aerosol generating matrix, preventing the flexible membrane 22 from deforming excessively downward. Similarly, after the atomizer 100 is flipped 180° (degrees), the boss 22b on the other flexible membrane 22 has the same effect, which will not be elaborated here.

[0063] For another example, when the atomizer 100 is in a horizontal position, the first direction can be consistent with the horizontal direction, that is, the two flexible parts 20 are spaced apart in the horizontal direction, and the liquid aerosol generating matrix applies an extrusion pressure toward the outside of the liquid storage chamber 10b to the two flexible parts 20. The inwardly protruding boss 22b can reduce or even offset the influence of the extrusion pressure of the liquid aerosol generating matrix, thereby preventing the flexible membrane 22 from deforming excessively outward.

[0064] It is understandable that, during the posture change of the atomizer 100, the boss 22b can also prevent the impact force generated by the movement of the liquid aerosol-generating matrix from causing excessive deformation of the flexible part 20, thereby improving the leak-proof performance of the liquid storage chamber 10b to adapt to different usage scenarios.

[0065] The first pressure-stabilizing groove 22a and the second pressure-stabilizing groove 22c may be in a closed ring structure or an open ring structure.

[0066] Please continue reading Figure 3 The first pressure-stabilizing groove 22a, the boss 22b, and the second pressure-stabilizing groove 22c together form a wavy structure. In other words, at least a portion of the flexible membrane 22 is wavy. This allows the flexible member 20 to elastically deform in response to changes in the external environment, improving the pressure-stabilizing performance of the liquid storage chamber 10b and effectively preventing leakage.

[0067] It should be noted that, in the present application, down refers to the direction toward the ground, up refers to the direction opposite to down, and the up and down directions are perpendicular to the horizontal direction.

[0068] For some examples, see Figures 2 to 4 The housing assembly 10 includes a nozzle 11, an inner shell 12 and a base 13. The nozzle 11 and the base 13 are respectively connected to two ends of the inner shell 12 along the first direction to jointly define a mounting cavity 10a.

[0069] For example, the mouthpiece 11 is formed with an airway 11c, through which the user can inhale the aerosol. The mouthpiece 11 and the base 13 are disposed on opposite sides of the inner shell 12 along the same direction, facilitating assembly of the atomizer 100. Furthermore, the mouthpiece 11, inner shell 12, and base 13 can be manufactured separately, reducing production complexity.

[0070] The nozzle 11, inner shell 12 and base 13 may all be transparent structures. A transparent structure refers to a structure with a light transmittance of not less than 90%. This makes it easier for the user to observe the remaining amount of liquid aerosol generating matrix in the liquid storage chamber 10b.

[0071] The specific materials of the nozzle 11, the inner shell 12 and the base 13 are not limited. For example, the nozzle 11, the inner shell 12 and the base 13 can all be made of PCTG (amorphous copolyester) material, which has the characteristics of high transparency and excellent impact resistance.

[0072] In one embodiment, the suction nozzle 11 can be detachably connected to the inner shell 12 .

[0073] In one embodiment, the base 13 can be detachably connected to the inner shell 12 .

[0074] Removable connections include but are not limited to snap connections, threaded connections, and the like.

[0075] In one embodiment, the mouthpiece 11 and the base 13 are both snap-fitted to the inner shell 12 , facilitating assembly of the atomizer 100 .

[0076] For some examples, see Figure 6 The flexible member 20 includes a first flexible member 20a, which is arranged on the side of the suction nozzle 11 close to the installation cavity 10a. A first pressure-stabilizing cavity 11a is formed between the first flexible member 20a and the suction nozzle 11, and the suction nozzle 11 is formed with an atmospheric communication hole 11b, which connects the first pressure-stabilizing cavity 11a with the outside atmosphere. In this way, the suction nozzle 11 plays a protective role, which can prevent the first flexible member 20a from touching external structures and prevent the first flexible member 20a from being damaged. The first pressure-stabilizing cavity 11a is connected to the outside atmosphere through the atmospheric communication hole 11b. The air pressure in the first pressure-stabilizing cavity 11a can be the same as the air pressure of the outside atmosphere. The first flexible member 20a maintains contact with the atmosphere, so that the first flexible member 20a can be deformed when the external environment changes.

[0077] For example, see Figure 8 There are multiple atmospheric communication holes 11b. For example, multiple atmospheric communication holes 11b are arranged at intervals around the airway 11c. In this way, the flow rate of the airflow can be increased so that the air pressure in the first pressure-stabilizing chamber 11a is consistent with the atmospheric pressure.

[0078] In one embodiment, please refer to Figure 6 and Figure 8 The suction nozzle 11 includes a suction nozzle portion 111 and a limiting ring 112. The limiting ring 112 connects the suction nozzle portion 111 to the side close to the installation cavity 10a and surrounds the circumferential portion of the suction nozzle portion 111. The connecting edge 21 of the first flexible part 20a is clamped between the limiting ring 112 and the shell wall surface of the inner shell 12. In this way, the connection stability between the first flexible part 20a and the shell assembly 10 can be enhanced.

[0079] For some examples, see Figure 7 and Figure 9 The housing assembly 10 includes a stopper 14, which extends along a circumferential surface in the first direction and seals against the wall of the liquid storage chamber 10b. The flexible member 20 includes a second flexible member 20b, which is clamped between the stopper 14 and the base 13. This provides protection for the base 13, preventing the second flexible member 20b from contacting external structures and damaging them. Furthermore, the clamping of the second flexible member 20b by the stopper 14 and the base 13 enhances the connection between the second flexible member 20b and the housing assembly 10.

[0080] For example, during the assembly of the second flexible member 20b, the second flexible member 20b may be placed on the limiting portion 14 first, and then the seat body 13 and the inner shell 12 are connected to complete the assembly, which facilitates the operation and improves the assembly efficiency.

[0081] In one embodiment, please refer to Figure 7 and Figure 10 The seat body 13 includes a base 131 and a limit platform 132. The limit platform 132 is connected to the base 131 on the side close to the installation cavity 10a. The connecting edge 21 of the second flexible member 20b is clamped between the circumferential surface of the limit platform 132 surrounding the first direction and the shell wall surface of the inner shell 12. In this way, the connection stability between the second flexible member 20b and the shell assembly 10 can be further enhanced.

[0082] For some examples, see Figures 9 to 11 The limiting portion 14 forms a first air inlet 14a connected to the liquid storage chamber 10b, the second flexible member 20b forms a second air inlet 20b1, and the seat body 13 forms a ventilation channel 13a. The first air inlet 14a, the second air inlet 20b1 and the ventilation channel 13a are connected to each other.

[0083] It should be noted that the air pressure within the liquid storage chamber 10b is less than atmospheric pressure and is negative relative to atmospheric pressure. In other words, the first air inlet 14a, the second air inlet 20b1, and the ventilation channel 13a together form a one-way passage. Thus, the liquid aerosol-generating substrate within the liquid storage chamber 10b cannot escape through the first air inlet 14a, the second air inlet 20b1, and the ventilation channel 13a. External air can enter the liquid storage chamber 10b through the ventilation channel 13a, the second air inlet 20b1, and the first air inlet 14a, in sequence.

[0084] For example, when the user inhales the aerosol, the liquid aerosol-generating matrix in the liquid storage chamber 10b gradually decreases, the cavity volume gradually increases, and the air pressure in the liquid storage chamber 10b gradually decreases. The outside air can enter the liquid storage chamber 10b through the ventilation channel 13a, the second air inlet 20b1 and the first air inlet 14a in sequence, and compensate for the air pressure in the liquid storage chamber 10b to maintain the air pressure stability of the liquid storage chamber 10b.

[0085] For some examples, see Figure 7 A second pressure-stabilizing chamber 13b is formed between the second flexible member 20b and the seat body 13. The seat body 13 is formed with a pressure-stabilizing hole 13c, which is connected to the second pressure-stabilizing chamber 13b.

[0086] The pressure-stabilizing hole 13c can be connected to the outside atmosphere, that is, the second pressure-stabilizing chamber 13b is connected to the outside atmosphere through the pressure-stabilizing hole 13c, and the air pressure in the second pressure-stabilizing chamber 13b can be the same as the air pressure of the outside atmosphere. The second flexible part 20b remains in contact with the atmosphere so that the second flexible part 20b can undergo elastic deformation when the external environment changes.

[0087] For some examples, see Figure 3 and Figure 4 The housing assembly 10 includes a protective shell 15. At least a portion of the inner shell 12 and the base 13 are located within the protective shell 15. A vacant cavity 15a is formed between the base 13 and the protective shell 15, which is connected to the outside atmosphere. Thus, the protective shell 15 provides protection, preventing at least a portion of the inner shell 12 and the base 13 from contacting and being damaged by external structures.

[0088] For example, see Figure 3 The pressure-stabilizing hole 13c is connected to the empty chamber 15a, and the second pressure-stabilizing chamber 13b is connected to the outside atmosphere through the pressure-stabilizing hole 13c and the empty chamber 15a. The air pressure in the second pressure-stabilizing chamber 13b can be the same as the air pressure of the outside atmosphere, and the second flexible part 20b maintains contact with the atmosphere so that the second flexible part 20b can undergo elastic deformation when the external environment changes.

[0089] The protective shell 15 may be a transparent structure.

[0090] The specific material of the protective shell 15 is not limited. For example, the protective shell 15 can be made of PCTG material, which is highly transparent and has excellent impact resistance. In this way, it is convenient for the user to observe the remaining amount of the liquid aerosol generating matrix in the liquid storage chamber 10b.

[0091] In one embodiment, the ventilation channel 13a is connected to the vacant cavity 15a, and the outside air can enter the liquid storage cavity 10b through the vacant cavity 15a, the ventilation channel 13a, the second air inlet 20b1 and the first air inlet 14a in sequence, compensating the air pressure of the liquid storage cavity 10b to maintain the air pressure stability of the liquid storage cavity 10b.

[0092] For some examples, see Figure 4 and Figure 10 The atomizer 100 includes a heating component 30, which is arranged on a side of the base 13 away from the second flexible member 20b. The second flexible member 20b is formed with a liquid outlet 20b2 connected to the liquid storage chamber 10b. The base 13 is formed with a liquid through port 13d. The liquid outlet 20b2 and the liquid through port 13d transport the liquid aerosol generating matrix to the heating component 30.

[0093] Illustratively, the heating assembly 30 includes a substrate and a heating element. The substrate includes a heating surface. A heating element is provided on the heating surface. The substrate can guide the liquid aerosol-generating matrix to the heating surface.

[0094] The substrate can be a porous structure. A porous structure refers to a structure with multiple interconnected pores and pores connected to the substrate's outer surface. The pores in a porous structure facilitate the temporary storage of the liquid aerosol-generating matrix and facilitate its circulation. The pores can also have a capillary effect, directing the liquid aerosol-generating matrix to the heating surface.

[0095] The pores in a porous structure can be arranged in a disordered manner. A disordered arrangement means that the pores are generated randomly without set rules.

[0096] The pores in the porous structure are micropores, that is, the hydraulic diameter of the pores is no greater than 100 μm (micrometers).

[0097] The hydraulic diameter is the ratio of four times the flow cross-sectional area to the perimeter. The flow cross-sectional area is the cross-sectional area perpendicular to the streamline cluster of the fluid.

[0098] The substrate can be made of ceramic. Ceramic materials have advantages such as good thermal conductivity and uniformity. For example, the substrate can be made of porous ceramic. Porous ceramic can be produced by high-temperature sintering of components such as aggregate, binder, and pore-forming agent.

[0099] The heating element may be a resistance heating wire, that is, the atomizer 100 generates aerosol by resistance heating.

[0100] In one embodiment, please refer to Figure 12 The base 13 is formed with a heating chamber 13e that communicates with the liquid passage 13d. The heating assembly 30 is accommodated within the heating chamber 13e, thereby enhancing the connection stability between the heating assembly 30 and the base 13. Exemplarily, a sealing member is sandwiched between the circumferential surface of the base and the wall surface of the heating chamber 13e. The sealing member provides a sealing function and effectively prevents leakage from the liquid storage chamber 10b.

[0101] For some examples, see Figure 3 、 Figure 4 and Figure 12 The atomizer 100 includes a conductive member 40, which is electrically connected to the heating element and is used to transmit external electrical energy to the heating element. At least a portion of the conductive member 40 is located within the vacant cavity 15a. In other words, at least a portion of the conductive member 40 is located within the protective shell 15. The protective shell 15 provides protection and prevents the conductive member 40 from contacting external structures.

[0102] For example, the conductive member 40 may be a thimble.

[0103] For some examples, see Figure 3 and Figure 4 The atomizer 100 includes a central tube 50, which is formed with an outlet passage 50a that communicates with the airway 11c. For example, the central tube 50 can pass through the through-hole 20c of the first flexible member 20a and the through-hole 20c of the second flexible member 20b, and extend to the heating assembly 30. It will be understood that the central tube 50 is in sealing contact with the through-hole 20c of the first flexible member 20a, and the central tube 50 is in sealing contact with the through-hole 20c of the second flexible member 20b. The aerosol generated by heating by the heating assembly 30 can flow through the outlet passage 50a to the airway 11c for inhalation by the user.

[0104] See also Figure 13 The embodiment of the present application also provides an electronic atomization device 1000, including a power supply component 200 and an atomizer 100 in any embodiment of the present application, and the power supply component 200 is used to supply power to the atomizer 100.

[0105] Illustratively, the power supply assembly 200 is electrically connected to the conductive member 40 , so that the power supply assembly 200 can supply power to the heating element through the conductive member 40 .

[0106] The power supply assembly 200 includes, but is not limited to, a device capable of providing electrical energy, such as a battery. The power supply assembly 200 includes, but is not limited to, a battery. The battery may be a disposable battery or a rechargeable battery.

[0107] Exemplarily, the electronic atomization device 1000 is a portable aerosol generating device. For example, the electronic atomization device 1000 can be a handheld aerosol generating device. The outline shape of the electronic atomization device 1000 can be roughly long and narrow. This makes it easier for the user to hold the electronic atomization device 1000.
