[0045] 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.

[0046] 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.

[0047] See also Figures 1 to 11 The embodiment of the present application provides an atomizer 100, comprising a housing assembly 10, an atomizer seat assembly 20, an atomizer core 30, and a conductive member 40. The housing assembly 10 has a mounting cavity 10a and an air flow channel 10b; the atomizer seat assembly 20 has a liquid inlet channel 20a, an air outlet channel 20b, and a placement cavity 20c. The atomizer seat assembly 20 is disposed in the mounting cavity 10a to define a portion of the mounting cavity 10a as a liquid storage cavity 10c. The liquid inlet channel 20a is connected to the liquid storage cavity 10c. The cavity 10c and the placement cavity 20c are connected by the air outlet channel 20b. The atomizer core 30 has an atomizing surface 30a and a power connection surface 30b. The atomizer core 30 is disposed in the placement cavity 20c, with the atomizing surface 30a facing the air outlet channel 20b. The aerosol-generating substrate in the liquid storage cavity 10c enters the atomizer core 30 through the liquid inlet channel 20a to generate an aerosol. A portion of the conductive member 40 extends into the placement cavity 20c and abuts the power connection surface 30b.

[0048] The atomizer 100 is used to heat a liquid aerosol-generating substrate to generate an aerosol that can be inhaled by a user. The liquid aerosol-generating substrate refers to a liquid fluid used for atomization to generate an aerosol.

[0049] Part of the mounting cavity 10a is used to house components such as the atomizer assembly 20. The atomizer assembly 20 defines the remaining portion of the mounting cavity 10a as a liquid storage chamber 10c, resulting in a compact overall structure for the atomizer 100. The liquid storage chamber 10c is used to hold liquid aerosol-generating substrate. Thus, the mounting cavity 10a serves both storage and placement functions, increasing the practicality of the housing assembly 10.

[0050] The liquid inlet channel 20a connects the liquid storage chamber 10c and the placement chamber 20c. This means that the liquid aerosol-generating substrate can be directed through the liquid inlet channel 20a to the atomizer core 30. The atomizer core 30 is used to absorb and heat the liquid aerosol-generating substrate to form an aerosol. For example, the electrical connection surface 30b can be used to conduct electricity and absorb the liquid aerosol-generating substrate. The liquid aerosol-generating substrate, guided by the atomizer core 30, flows to the atomizing surface 30a where it is heated to generate an aerosol.

[0051] The atomizing surface 30a is oriented toward the air outlet channel 20b, which means that the normal direction of the atomizing surface 30a is substantially consistent with the extension direction of the air outlet channel 20b. For example, with the atomizing surface 30a as the projection surface, the projection of the atomizing surface 30a and the projection of the air outlet channel 20b at least partially overlap. For example, the air outlet channel 20b is oriented toward the air flow channel 10b, and the extension direction of the air flow channel 10b is consistent with the extension direction of the air outlet channel 20b. In this way, the aerosol can flow directly toward the air outlet channel 20b and flow out through the air flow channel 10b for the user to inhale. For example, please refer to Figure 3 and Figure 4 The air flow channel 10b and the air outlet channel 20b both extend along the length direction of the atomizer 100. In this way, the flow direction of the aerosol in the air flow channel 10b and the air outlet channel 20b basically does not change, which can reduce the loss of the aerosol during the flow process. The user can inhale a relatively rich aerosol, thereby improving the user experience.

[0052] The specific shape of the atomizer core 30 is not limited, and can be, for example, a rectangular parallelepiped, a cylinder, or an elliptical cylinder. Taking the atomizer core 30 as an example, the overall structure of the atomizer core 30 is regular, easy to arrange, and helpful in reducing the gap between the atomizer core 30 and other components.

[0053] For example, the thickness of the rectangular atomizer core 30 is between 0.6 mm (millimeter) and 1.5 mm, for example, 0.6 mm, 0.8 mm, 1.0 mm, 1.2 mm, 1.4 mm or 1.5 mm, etc. By setting appropriate dimensions, it can be adapted to placement cavities 20 c of different sizes.

[0054] The conductive member 40 is electrically connected to the atomizer core 30 via the power contact surface 30b to transmit external electrical energy to the atomizer core 30. When powered, the atomizer core 30 can heat the liquid aerosol-generating substrate to form an aerosol.

[0055] The conductive member 40 abuts against the electrical contact surface 30b, which not only serves as a conductive connection, but also provides support for the atomizer core 30 to press the atomizer core 30 tightly against the atomizer seat assembly 20. The conductive member 40 fixes the atomizer core 30, preventing the atomizer core 30 from being disturbed and displaced, thereby enhancing the stability of the atomizer core 30. It can also reduce the number of parts required to fix the atomizer core 30 and reduce costs.

[0056] Part of the conductive member 40 is located in the placement cavity 20c. This can reduce the space outside the placement cavity 20c occupied by the conductive member 40, which is beneficial for the atomizer 100 to be small and compact.

[0057] For example, the conductive member 40 may be a pin.

[0058] The atomizer 100 provided in the embodiment of the present application has an atomizing surface 30a facing the air outlet channel 20b, which can reduce the resistance encountered during the flow of the aerosol. The aerosol can flow through the air outlet channel 20b to the air flow channel 10b for the user to inhale, which can reduce the loss of the aerosol during the flow process. The user can inhale an aerosol with a richer taste, thereby improving the user experience. The conductive member 40 fixes the atomizer core 30, preventing the atomizer core 30 from being disturbed and displaced, enhancing the stability of the atomizer core 30, and reducing the parts required to fix the atomizer core 30, thereby reducing costs. In addition, part of the conductive member 40 is accommodated in the placement cavity 20c, reducing the space occupied outside the placement cavity 20c, which is beneficial for the atomizer 100 to be small and compact.

[0059] In one embodiment, the atomizing core 30 includes a base and a heating element. The base has an atomizing surface 30 a , and the heating element is disposed on the atomizing surface 30 a . The base can guide the liquid aerosol-generating matrix to the atomizing surface 30 a .

[0060] 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.

[0061] 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.

[0062] The pores in the porous structure are micropores, that is, the hydraulic diameter of the pores is no greater than 100 μm (micrometers).

[0063] 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.

[0064] The specific material of the substrate is not limited. For example, the substrate can be made of a conductive material, such as conductive ceramic, nickel-chromium, stainless steel, or other metals or alloys. This eliminates the need to drill holes in the substrate to run wires for power transmission, ensuring the integrity of the internal structure of the substrate and effectively ensuring the consistency of the atomizer core 30. Furthermore, the use of wires can be avoided, reducing production costs and assembly difficulty.

[0065] It should be noted that, in this application, a plurality refers to a quantity including two or more.

[0066] In one embodiment, please refer to Figure 5 The power-connecting surface 30 b and the atomizing surface 30 a are substantially parallel. Thus, the liquid aerosol-generating substrate can be more evenly guided from the power-connecting surface 30 b to the atomizing surface 30 a, thereby improving the atomization efficiency of the atomizing core 30 .

[0067] For some examples, see Figures 5 to 8 The atomizer seat assembly 20 includes an atomizer seat 21 and a first sealing member. The atomizer seat 21 forms a placement cavity 20c. The first sealing member includes a first side wall 221 having an avoidance port 221a. The first side wall 221 is arranged in the placement cavity 20c. The avoidance port 221a faces the air outlet channel 20b. One side surface of the first side wall 221 along the thickness direction abuts against the surrounding part of the air outlet channel 20b, and the other side surface of the first side wall 221 along the thickness direction abuts against a portion of the atomizing surface 30a.

[0068] The first sidewall 221 is sealed and clamped between the atomizing surface 30a and the surrounding area of ​​the air outlet channel 20b. The first sidewall 221 acts as a seal to prevent aerosol and liquid aerosol-generating substrate from leaking out from between the atomizer seat 21 and the atomizer core 30. The avoidance port 221a faces the air outlet channel 20b, meaning that the avoidance port 221a is oriented in the same direction as the extension of the air outlet channel 20b. The avoidance port 221a is connected to the air outlet channel 20b, allowing aerosol to flow directly to the air outlet channel 20b through the avoidance port 221a, thereby reducing aerosol loss during flow.

[0069] In one embodiment, one side of the first sidewall 221 along the thickness direction seals against the portion surrounding the air outlet channel 20b, while the other side of the first sidewall 221 along the thickness direction seals against the portion of the atomizing surface 30a. This enhances the sealing performance of the atomizer 100 and prevents leakage of the liquid aerosol-generating substrate.

[0070] The first seal can be made of a flexible material. A flexible material refers to a material that can bend, fold, twist, compress, and / or stretch. In other words, the first sidewall 221 is in flexible contact with the atomizer seat 21 and the atomizer core 30. The elastic deformation properties of the first seal can mitigate vibrations transmitted to the atomizer core 30, preventing damage to the atomizer core 30 and providing better protection.

[0071] The specific material of the first sealing member is not limited, and for example, it can be made of silicone material.

[0072] In one embodiment, the first sealing member is an integrally formed structure. For example, the first sealing member may be an integrally formed structure formed by injection molding, compression molding, or other processes.

[0073] For some examples, see Figure 3 and Figure 5The electrical connection surface 30b is located on the side of the atomizing surface 30a away from the first sidewall 221. The conductive member 40 abuts the electrical connection surface 30b to tighten the first sidewall 221 to the periphery of the air outlet channel 20b. On a projection plane parallel to the atomizing surface 30a, the projection of the central axis L of the conductive member 40 is located within the overlapping range of the projections of the atomizer seat 21, the atomizer core 30, and the first sidewall 221. In other words, the conductive member 40 provides a supporting force to elastically deform the first sidewall 221, thereby sealing the gap between the atomizer core 30 and the periphery of the air outlet channel 20b. Thus, the reinforcing effect of the conductive member 40 can further enhance the sealing performance of the first sidewall 221.

[0074] For example, see Figure 5 The atomizing surface 30a and the electrical connection surface 30b are respectively formed on either side of the atomizer core 30 along the thickness direction. In other words, the conductive member 40 and the first side wall 221 are respectively located on either side of the atomizer core 30 along the thickness direction. Thus, during assembly of the atomizer 100, the first side wall 221 can be first assembled into the placement cavity 20c, the atomizer core 30 can then be stacked on the first side wall 221, and finally the conductive member 40 can be assembled so that the first side wall 221 is tightly against the area surrounding the air outlet channel 20b. This facilitates operation and improves assembly efficiency.

[0075] For example, see Figure 3 On a projection plane parallel to the atomizing surface 30a, the projection of the central axis L of the conductive member 40 lies within the overlapping range of the projections of the atomizer seat 21, the atomizer core 30, and the first sidewall 221. This allows the force applied by the conductive member 40 on the atomizer core 30 to be fully transmitted to the first sidewall 221, and then, through the first sidewall 221, to act on the area surrounding the air outlet channel 20b, i.e., on the atomizer seat 21. This enhances the connection stability of the first sealing member and further improves the sealing performance of the first sidewall 221.

[0076] For some examples, see Figure 6 and Figure 7 The atomizer seat 21 is formed with a liquid-passing section 21a. The first sealing member includes an annular wall 222. The annular wall 222 surrounds the outer periphery of the first side wall 221 to jointly define an opening groove 22a. The atomizer core 30 is located in the opening groove 22a. The annular wall 222 has a liquid inlet 222a. The liquid inlet 222a and the liquid-passing section 21a are at least part of the liquid inlet channel 20a. The opening groove 22a plays a limiting role, which can prevent the atomizer core 30 from being disturbed and displaced. Exemplarily, the first side wall 221 can be a roughly flat plate structure, and the annular wall 222 can be a roughly annular structure. In this way, it is easy to manufacture and form.

[0077] The opening groove 22a is connected to the liquid inlet 222a, and the liquid inlet 222a is connected to the liquid passage section 21a. The liquid aerosol-generating substrate flows into the opening groove 22a under the guidance of the liquid passage section 21a and the liquid inlet 222a. Figure 6 and Figure 10 There are two liquid passage sections 21a and two liquid inlets 222a. The two liquid inlets 222a are located on opposite sides of the annular wall 222 along the circumferential direction. The two liquid passage sections 21a are located on opposite sides of the atomizer seat 21 along the circumferential direction. Each liquid inlet 222a faces the corresponding liquid passage section 21a. This increases the flow rate of the liquid aerosol-generating substrate, allowing it to flow more evenly through the liquid inlet channel 20a into the placement chamber 20c, thereby improving the atomization efficiency of the atomizer 100.

[0078] For some examples, see Figure 5 、 Figure 8 and Figure 9 The housing assembly 10 includes a base 11. The first sealing member includes a flange 223 surrounding the outer periphery of an annular wall 222. The atomizer seat 21 has a first clamping surface 21b and a placement opening 21c communicating with the placement chamber 20c. The first clamping surface 21b surrounds the outer periphery of the placement opening 21c. The flange 223 is clamped between the first clamping surface 21b and the second clamping surface 11a of the base 11. The flange 223 is sealed between the first clamping surface 21b and the second clamping surface 11a. The flange 223 acts as a seal, preventing the liquid aerosol-generating substrate from leaking outward from between the first clamping surface 21b and the second clamping surface 11a, thereby improving the sealing performance of the atomizer 100.

[0079] For example, using a flexible material for the flange 223 means that the flange 223 forms a flexible contact with both the first clamping surface 21b and the second clamping surface 11a. This, on the one hand, separates the first clamping surface 21b from the second clamping surface 11a, preventing wear and tear between the first clamping surface 21b and the second clamping surface 11a. On the other hand, it reduces vibration transmitted between the atomizer seat 21 and the base 11, preventing damage to the atomizer seat 21 and the base 11, and providing better protection.

[0080] In one embodiment, the atomizer seat 21 and the base 11 are detachably connected, for example, by a snap connection, to facilitate assembly of the atomizer 100 .

[0081] For some examples, see Figure 6 and Figure 10The atomizer seat assembly 20 includes a second sealing member 23, which includes a second sidewall 231 and a peripheral wall 232. The peripheral wall 232 surrounds the second sidewall 231 and is clamped between the cavity wall of the mounting cavity 10a and the atomizer seat 21. The second sidewall 231 is formed with a liquid supply port 231a. The liquid supply port 231a and the liquid passage section 21a constitute at least part of the liquid inlet channel 20a. The second sidewall 231 can be generally flat, and the peripheral wall 232 can be generally annular. The outer wall 232 is sealed and clamped between the cavity wall surface of the mounting cavity 10a and the atomizer seat 21. That is, the clamping force between the cavity wall surface of the mounting cavity 10a and the atomizer seat 21 causes the outer wall 232 to elastically deform to seal the gap between the cavity wall surface of the mounting cavity 10a and the atomizer seat 21. The outer wall 232 plays a sealing role, which can prevent the liquid aerosol-generating matrix from seeping out from between the cavity wall surface of the atomizer seat 21 and the cavity wall surface of the mounting cavity 10a, thereby improving the sealing performance of the atomizer 100.

[0082] The liquid supply port 231a, the liquid passage section 21a and the liquid inlet 222a are sequentially connected, and the liquid aerosol generating substrate flows to the opening groove 22a through the liquid supply port 231a, the liquid passage section 21a and the liquid inlet 222a. Figure 4 and Figure 5 At least a portion of the second sidewall 231 overlaps the side of the atomizer seat 21 facing the liquid storage chamber 10c to enhance the connection stability between the atomizer seat 21 and the second sealing member 23. Furthermore, at least a portion of the liquid supply port 231a faces the liquid passage section 21a. In this way, the liquid aerosol-generating substrate can flow directly into the liquid passage section 21a through the liquid supply port 231a, thereby reducing the resistance encountered by the liquid aerosol-generating substrate during flow.

[0083] The second sealing member 23 can be made of a flexible material. In other words, the outer wall 232 is in flexible contact with both the atomizer seat 21 and the walls of the mounting cavity 10a. This reduces vibrations transmitted between the atomizer seat 21 and the housing assembly 10, preventing damage to the atomizer seat 21 and the housing assembly 10 and providing improved protection.

[0084] The specific material of the second sealing member 23 is not limited, and for example, it can be made of silicone material.

[0085] In one embodiment, the second sealing member 23 is an integrally formed structure. For example, the second sealing member 23 can be an integrally formed structure formed by injection molding, compression molding, or other processes.

[0086] In one embodiment, please refer to Figure 10 The outer peripheral surface of the outer wall 232 is formed with a plurality of annular protrusions 2321 . The plurality of protrusions 2321 act as a multi-layer seal, thereby improving the sealing performance of the atomizer 100 .

[0087] For some examples, see Figure 5 、 Figure 6 and Figure 10 The atomizer seat 21 forms an air outlet channel 20b. The second side wall 231 is formed with an airflow outlet 231b and an inner surrounding wall 2311. The inner surrounding wall 2311 surrounds the airflow outlet 231b and is clamped between the airflow channel 10b and the air outlet channel 20b. The inner surrounding wall 2311 is sealed and clamped between the airflow channel 10b and the air outlet channel 20b. In other words, the clamping force between the airflow channel 10b and the air outlet channel 20b causes the inner surrounding wall 2311 to elastically deform. In this way, the inner surrounding wall 2311 can seal the gap between the airflow channel 10b and the air outlet channel 20b, preventing aerosol leakage and achieving a good sealing effect.

[0088] For example, please see Figure 5 , airflow channel 10b partially extends into outlet channel 20b. This positioning and securing of outlet channel 20b facilitates assembly of airflow channel 10b and outlet channel 20b, enhancing the stability of the connection. Furthermore, aerosol can flow smoothly through outlet channel 20b into airflow channel 10b, facilitating aerosol inhalation by the user, reducing aerosol loss, and increasing the number of puffs a user can take.

[0089] For some examples, see Figure 4 The atomizer seat assembly 20 has an air inlet channel 20d, which connects the air outlet channel 20b and the atmosphere. In other words, outside air can enter the atomizer 100 through the air inlet channel 20d, and the airflow carries the aerosol through the air outlet channel 20b and the airflow channel 10b for the user to inhale. In this way, the aerosol can be fully mixed with the air, improving the taste. At the same time, the temperature of the outside air is lower than that of the liquid aerosol-generating matrix heated by the atomizer core 30. The air can lower the temperature of the aerosol at the air outlet channel 20b, thereby improving the user experience.

[0090] For some examples, see Figure 6 and Figure 10 The atomizer seat 21 is formed with a ventilation section 21d, and the peripheral wall 232 is formed with an air flow inlet 232a. The air flow inlet 232a and the ventilation section 21d are at least part of the air inlet channel 20d of the atomizer seat assembly 20. In other words, the air flow inlet 232a and the ventilation section 21d are connected, and the outside air flows to the air outlet channel 20b through the air flow inlet 232a and the ventilation section 21d in sequence.

[0091] For example, see Figure 6 and Figure 10There are two ventilation sections 21d and two air inlets 232a. The two ventilation sections 21d are located on opposite sides of the atomizer base 21 along the circumference, and the two air inlets 232a are located on opposite sides of the outer wall 232 along the circumference. Each channel section faces the corresponding air inlet 232a. This increases the flow rate of airflow, allowing airflow to flow more evenly through the air inlet channel 20d to the air outlet channel 20b, thereby improving the atomization efficiency of the atomizer 100.

[0092] In one embodiment, please refer to Figure 6 The two liquid-passing sections 21a are provided on opposite sides of the atomizing seat 21 along the width direction. The two ventilation sections 21d are provided on opposite sides of the atomizing seat 21 along the thickness direction.

[0093] For some examples, see Figure 2 and Figure 11 The housing assembly 10 includes a nozzle 12 and a base 11. The nozzle 12 defines an airflow channel 10b, an open cavity 12a, and a mounting opening 12b communicating with the open cavity 12a. The base 11 seals the mounting opening 12b, defining the open cavity 12a as the mounting cavity 10a. The base 11 seals the mounting opening 12b, allowing the user to inhale aerosols through the nozzle 12. The base 11 seals the mounting opening 12b and prevents foreign matter from entering the mounting cavity 10a.

[0094] The specific materials of the nozzle 12 and the base 11 are not limited, and the nozzle 12 and the base 11 can both be made of plastic.

[0095] In one embodiment, the nozzle 12 can be detachably connected to the base 11. Detachable connections include but are not limited to snap connections, threaded connections, etc. Exemplarily, the nozzle 12 is snap-connected to the base 11 to facilitate assembly of the atomizer 100.

[0096] For some examples, see Figures 2 to 4 The atomizer 100 includes a sealing ring 50, which seals between the circumferential surface of the base 11 and the wall of the mounting cavity 10a. The sealing ring 50 is located on the side of the second sealing member 23 that is away from the liquid storage cavity 10c. Thus, the sealing ring 50 and the second sealing member 23 form a multi-layer seal, effectively preventing the liquid aerosol-generating matrix from leaking outward and preventing external air from entering the mounting cavity 10a. This maintains the air pressure stability of the liquid storage cavity 10c and further enhances the sealing performance of the atomizer 100.

[0097] For some examples, see Figure 5 The electrical contact surface 30b is located on the side of the atomizing surface 30a away from the air outlet channel 20b. In other words, the conductive member 40 and the air outlet channel 20b are located on opposite sides of the atomizing core 30, which can reduce the difficulty of assembling the atomizer 100.

[0098] For some examples, see Figure 5 The air inlet channel 20d has a guide surface 20d1 that slopes from the distal lip end 20d3 to the proximal lip end 20d2 toward the air outlet channel 20b. The guide surface 20d1 guides the airflow, allowing the airflow to flow smoothly through the air inlet channel 20d to the air outlet channel 20b.

[0099] It should be noted that the distal lip end 20d3 refers to the end of the atomizer 100 that is away from the user's lips when in use, and the proximal lip end 20d2 faces opposite to the distal lip end 20d3. The proximal lip end 20d2 refers to the end of the atomizer 100 that is closer to the user's lips when in use. Taking the atomizer 100 as an example, the distal lip end 20d3 and the proximal lip end 20d2 of the atomizer 100 can be opposite ends along the length direction.

[0100] For example, please see Figure 5 The guide surface 20d1 can be the wall surface of the ventilation section 21d, wherein the proximal lip end 20d2 of the guide surface 20d1 is closer to the air outlet channel 20b than the distal lip end 20d3. That is to say, an angle less than 90° is formed between the ventilation section 21d and the air outlet channel 20b, preventing the flow direction of the external air from being perpendicular to the direction of the aerosol released after the atomization core 30 atomizes the liquid aerosol to generate the matrix. This allows the air to flow more smoothly and gently through the ventilation section 21d into the air outlet channel 20b, reducing the resistance during the air flow process. The air can be fully mixed with the aerosol, thereby improving the taste and enhancing the user experience.

[0101] For some examples, see Figure 7 The atomizing surface 30a has a heating area 30a1. With the atomizing surface 30a as the projection surface, the projection of the heating area 30a1 is located within the projection range of the airflow channel 10b. For example, the heating area 30a1 is provided with a heating element, which is used to heat the liquid aerosol-generating matrix to form the aerosol. This prevents the aerosol from being blocked during its flow through the air outlet channel 20b and the avoidance port 221a, reduces aerosol loss during flow, and maintains the original rich taste of the aerosol, improving the user experience.

[0102] See also Figure 12 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.

[0103] For example, the power supply assembly 200 is electrically connected to the conductive member 40, and the power supply assembly 200 can supply power to the atomizer core 30 through the conductive member 40. 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 can be a disposable battery or a rechargeable battery.

[0104] In one embodiment, 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 electronic atomization device 1000 can be roughly rectangular in shape. This makes it easier for a user to hold the electronic atomization device 1000.
