Description

Technical Field

[0001] This application relates to the field of aerosol supply technology, and in particular to an apparatus and an aerosol supply system for use in an aerosol supply system. Background Technology

[0002] Electronic cigarettes are aerosol supply systems that heat but do not burn aerosol-generating materials (such as tobacco) to produce an aerosol matrix. They typically use devices like atomizers to heat the aerosol-generating material to a sufficiently high temperature to generate an aerosol for the user to inhale. These systems usually use batteries to power the atomizer. Ideally, power should be transferred seamlessly from the battery to the atomizer core. However, in actual use, various factors can cause instability in the electrical connection between the battery and the atomizer. For example, insufficient mechanical pressure between the battery and the atomizer can significantly increase the contact resistance at the interface, resulting in lower-than-set power reaching the atomizer core, reduced effective output power, and severely impacting atomization efficiency. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes an apparatus and an aerosol supply system for an aerosol supply system to solve technical problems such as how to ensure the stability of the electrical connection between the battery and the atomizer.

[0004] In a first aspect, this application provides an apparatus for an aerosol supply system, including an electrode structure comprising:

[0005] The first contact portion is configured to be electrically connected to an internal component of the device;

[0006] The second contact portion is configured to have a contact surface that connects to the electrodes of an external component to form an electrical connection;

[0007] An elastic arm is configured to have its two ends electrically connected to the first contact portion and the second contact portion, respectively, and the extension direction of the elastic arm is perpendicular to the orientation of the contact surface.

[0008] In this embodiment, by configuring the extension direction of the elastic arm connected between the first contact portion and the second contact portion to be perpendicular to the orientation of the contact surface of the second contact portion, the elastic deformation and rebound capabilities of the elastic arm can be utilized to the maximum extent. When the contact surface of the second contact portion is connected to the electrode of the external component, the second contact portion can press the electrode of the external component under the action of the elastic arm to ensure that a stable electrical connection is formed between the second contact portion and the electrode of the external component.

[0009] In one technical solution of the above-described device for an aerosol supply system, the second contact portion is in its initial position when it is not connected to the electrode of the external component.

[0010] When the second contact portion is connected to the electrode of the external element, the elastic arm deforms and moves the second contact portion so that the second contact portion presses against the electrode of the external element.

[0011] In this embodiment, when the second contact portion is connected to the electrode of an external component, the pressure from the electrode of the external component causes the elastic arm to move away from the electrode. This deformation of the elastic arm generates an elastic force opposite to the direction of movement, causing the elastic arm to push the second contact portion towards the electrode of the external component. This allows the second contact portion to press against the electrode of the external component, thus forming a stable electrical connection between the second contact portion and the electrode of the external component. When the second contact portion is disconnected from the electrode of the external component, the pressure from the electrode of the external component disappears. Due to its inherent resilience, the elastic arm continues to move the second contact portion towards the electrode of the external component, returning the second contact portion to its initial position.

[0012] In one technical solution of the above-described device for an aerosol supply system, the elastic arm extends laterally along the device, and the contact surface faces longitudinally towards the device; or,

[0015] In one technical solution of the above-mentioned device for an aerosol supply system, the second contact portion can move within a stroke range of 0.1~2mm under the drive of the elastic arm.

[0016] In one technical solution of the above-mentioned device for an aerosol supply system, the clamping force of the second contact portion pressing the electrode of the external element is 0.1-5N.

[0017] In one embodiment of the above-described apparatus for an aerosol supply system, the elastic arm includes at least one bent portion.

[0018] In this embodiment of the application, by configuring the elastic arm to include at least one bending portion, the length of the elastic arm in its extension direction can be increased as much as possible within a limited space, thereby increasing the bending deformation of the elastic arm and improving its elastic deformation capability.

[0019] In one technical solution of the above-mentioned device for an aerosol supply system, the bending portion includes at least one of an arc-shaped structure, an S-shaped structure, a V-shaped structure, a U-shaped structure, an Ω-shaped structure, or a spiral structure.

[0020] In one technical solution of the above-mentioned device for an aerosol supply system, the elastic arm is made of at least one of copper alloy, steel, titanium alloy, silver alloy and aluminum alloy.

[0021] In one technical solution of the above-mentioned device for an aerosol supply system, the second contact portion has a sheet-like structure.

[0022] In one technical solution of the above-mentioned device for an aerosol supply system, the material of the second contact part is at least one of copper alloy, steel, titanium alloy, silver alloy and aluminum alloy.

[0023] In one technical solution of the above-described device for an aerosol supply system, the extending direction of the first contact portion is set at an angle to the extending direction of the elastic arm.

[0024] In one embodiment of the above-described apparatus for an aerosol supply system, the elastic arm is located inside the apparatus, and at least a portion of the contact surface is exposed outside the apparatus.

[0025] In one technical solution of the above-described device for an aerosol supply system, the device includes a battery assembly, the first contact portion being electrically connected to the battery assembly; the external element includes an atomizer, and the contact surface of the second contact portion abuts against the electrode of the atomizer to form an electrical connection;

[0026] Alternatively, the device includes an atomizer, the first contact portion being electrically connected to the atomizer; the external element includes a battery assembly, the contact surface of the second contact portion abutting against the electrodes of the battery assembly to form an electrical connection.

[0027] In a second aspect, this application provides an aerosol supply system, the system comprising an apparatus for an aerosol supply system as described in any of the first aspects and an external element, wherein the electrodes of the external element are connected to the contact surface to form an electrical connection.

[0028] The above-described technical solutions of this application have at least one or more of the following beneficial effects:

[0029] In implementing the technical solution of this application, by configuring the electrode structure to include a first contact portion, a second contact portion, and an elastic arm connecting the first contact portion and the second contact portion, and configuring the first contact portion to be electrically connected to the internal components of the device, configuring the second contact portion to be electrically connected to the electrodes of the external components and having a contact surface electrically connected to the electrodes of the external components, and configuring the extension direction of the elastic arm to be perpendicular to the orientation of the contact surface of the second contact portion, the elastic deformation and rebound capabilities of the elastic arm can be maximized. When the contact surface of the second contact portion is connected to the electrodes of the external components, the second contact portion can press the electrodes of the external components under the action of the elastic arm to ensure that a stable electrical connection is formed between the second contact portion and the electrodes of the external components.

[0070] Aerosol-generating materials are materials capable of generating aerosols, for example, when heated, irradiated, or electrified in any other way. Aerosol-generating materials may be in solid, liquid, or gel form, and may or may not contain active substances and / or fragrances. In some embodiments, aerosol-generating materials may include “amorphous solids,” which may alternatively be referred to as “monolithic solids” (i.e., non-fibrous). In some embodiments, the amorphous solid may be a dried gel. An amorphous solid is a solid material that can retain some fluid (e.g., liquid) within it. In some embodiments, aerosol-generating materials may, for example, comprise from about 50 wt%, 60 wt%, or 70 wt% amorphous solids to about 90 wt%, 95 wt%, or 100 wt% amorphous solids.

[0075] Consumables are articles comprising or composed of aerosol-generating materials, some or all of which are intended to be consumed by a user during use. Consumables may include one or more other components, such as an aerosol-generating material storage area, an aerosol-generating material delivery component, an aerosol-generating area, a housing, packaging paper, a nozzle, a filter, and / or an aerosol modifier. Consumables may also include an aerosol generator, such as a heater, which releases heat during use to cause the aerosol-generating material to generate an aerosol. The heater may, for example, comprise a combustible material, a material that can be heated by electrical conduction, or a sensor.

[0076] A sensor is a material that can be heated by being penetrated by a changing magnetic field (such as an alternating magnetic field). A sensor can be a conductive material, such that penetration by a changing magnetic field results in inductive heating of the heating material. A heating material can be a magnetic material, such that penetration by a changing magnetic field results in hysteresis heating of the heating material. A sensor can be both conductive and magnetic, allowing it to be heated by both heating mechanisms. In this paper, a device constructed to generate a changing magnetic field is referred to as a magnetic field generator.

[0077] Aerosol modifiers are substances typically located downstream of the aerosol generation region, configured to modify the generated aerosols, for example, by altering their taste, flavor, acidity, or other properties. Aerosol modifiers can be disposed in aerosol modifier release components operable to selectively release the aerosol modifier. For example, aerosol modifiers can be additives or adsorbents. For example, aerosol modifiers may include one or more of fragrances, colorants, water, and carbon adsorbents. For example, aerosol modifiers can be solid, liquid, or gel. Aerosol modifiers can be in powder, filament, or granular form. Aerosol modifiers may not contain filter material.

[0078] An aerosol generator is a device configured to cause the generation of aerosols from an aerosol-generating material. In some embodiments, an aerosol generator is a heater configured to subject the aerosol-generating material to heat energy in order to release one or more volatiles from the aerosol-generating material to form an aerosol. In some embodiments, an aerosol generator is configured to cause the generation of aerosols from an aerosol-generating material without heating. For example, an aerosol generator may be configured to subject the aerosol-generating material to one or more of vibration, increased pressure, or electrostatic energy.

[0079] This disclosure relates to aerosol delivery systems (which may also be referred to as vapor delivery systems), such as aerosol sprayers or electronic cigarettes. In the following description, the terms "electronic cigarette" or "electronic cigarette" may sometimes be used, but it will be understood that this term is used interchangeably with aerosol delivery systems / devices and electronic aerosol delivery systems / devices. Furthermore, as is common in the art, the terms "aerosol" and "vapor," as well as related terms such as "evaporation," "atomization," and "aerosolization," are generally used interchangeably.

[0080] Aerosol delivery systems (electronic cigarettes) typically (though not always) comprise modular components, including reusable device parts and replaceable (disposable / consumable) cartridge parts. Typically, the replaceable cartridge part will include aerosol generating material and an vaporizer (which may be collectively referred to as an "atomizer"), and the reusable device part will include a power source (e.g., a rechargeable power supply) and control circuitry. It will be understood that these different parts may include additional components depending on their function. For example, the reusable device part will typically include a user interface for receiving user input and displaying operational status characteristics, and the replaceable cartridge device part may include, in some cases, a temperature sensor to aid in temperature control. The cartridge is electrically and mechanically connected to the control unit for use, for example, using threads, bayonet connections, or magnetic connections with suitably arranged electrical contacts. When the aerosol generating material in the cartridge is depleted, or when the user wishes to switch to a different cartridge with a different aerosol generating material, the cartridge can be removed from the reusable part, and a replacement cartridge can be attached to its appropriate position. Systems and devices that conform to this type of two-piece modular configuration can generally be referred to as two-piece systems / devices.

[0081] Electronic cigarettes typically have a generally elongated shape. For the sake of specific examples, some embodiments of this disclosure will be considered to include such a generally elongated two-piece system employing a disposable cartridge. However, it will be understood that the basic principles described herein can be equally applied to different constructions, such as single-piece systems or modular systems comprising more than two components, refillable devices and single-use disposable items, as well as other overall shapes, such as high-performance devices based on a so-called box-shaped pattern that typically has a box-like shape. More generally, it will be understood that some embodiments of this disclosure are based on aerosol delivery systems that are operatively configured to provide the functionality according to the principles described herein, and the construction aspects of the system configured to provide the functionality according to some embodiments of this disclosure are not of primary importance.

[0082] As described in the background section, existing aerosol supply systems suffer from technical problems such as a significant increase in contact resistance at the interface between the battery and the atomizer when the mechanical pressure between them is insufficient. This results in the actual power reaching the atomizer core being lower than the set value, which reduces the effective output power and seriously affects atomization efficiency.

[0083] To address the aforementioned problems, this application creatively proposes a novel device for an aerosol supply system. The electrode structure of this device includes a first contact portion, a second contact portion, and an elastic arm connecting the first and second contact portions. The first contact portion is electrically connected to an internal component of the device, and the second contact portion is electrically connected to the electrode of an external component and has a contact surface for electrical connection with the electrode of the external component. The extension direction of the elastic arm is perpendicular to the orientation of the contact surface of the second contact portion, maximizing the utilization of the elastic deformation and rebound capabilities of the elastic arm. When the contact surface of the second contact portion is connected to the electrode of the external component, the second contact portion can press against the electrode of the external component under the action of the elastic arm, ensuring a stable electrical connection between the second contact portion and the electrode of the external component.

[0084] It should be noted that the device for an aerosol supply system provided in this application embodiment can be applied to both pen-type aerosol supply systems and box-type aerosol supply systems, and no specific limitation is made here.

Figure 3 This is an exploded view of the device and external components for an aerosol supply system provided in the embodiments of this application. Figure 4 This is a schematic diagram of the electrode structure provided in the embodiments of this application, with reference to... Figures 1 to 4 As shown, the device includes an electrode structure 100 and a housing 200. A cavity 210 is formed inside the housing 200, and at least a portion of the electrode structure 100 is disposed within this cavity 210. The electrode structure 100 includes a first contact portion 110, a second contact portion 120, and an elastic arm 130. The first contact portion 110 is configured to be electrically connected to an internal component of the device. The second contact portion 120 is configured to be electrically connected to an electrode of an external component, and the second contact portion 120 has a contact surface 121 for connecting to the electrode of the external component. The elastic arm 130 is configured such that its extending direction is perpendicular to the orientation of the contact surface 121 of the second contact portion 120, so that the elastic deformation and rebound capabilities of the elastic arm 130 can be maximized. When the contact surface 121 of the second contact portion 120 is connected to the electrode of the external component, the second contact portion 120 can press against the electrode of the external component under the action of the elastic arm 130, ensuring a stable electrical connection between the second contact portion 120 and the electrode of the external component.

[0087] It is understood that in the embodiments of this application, the second contact portion 120 and the elastic arm 130 each have opposite front and back sides. The front sides of the second contact portion 120 and the elastic arm 130 face the same direction as the contact surface 121, and the back sides of the second contact portion 120 and the elastic arm 130 face opposite to the contact surface 121. The device for the aerosol supply system has a certain movable space on the back sides of the second contact portion 120 and the elastic arm 130, within which the second contact portion 120 and the elastic arm 130 can reciprocate.

[0088] In some specific embodiments, when the second contact portion 120 is not connected to the electrode of the external element (i.e., the second contact portion 120 is not compressed by the electrode of the external element), the second contact portion 120 is in its initial position. When the second contact portion 120 is connected to the electrode of the external element, the second contact portion 120 is subjected to the compressive force from the electrode of the external element. Therefore, the second contact portion 120 drives the elastic arm 130 to move away from the electrode of the external element, causing the elastic arm 130 to deform and generate an elastic force opposite to the direction of movement. This causes the elastic arm 130 to drive the second contact portion 120 to move towards the electrode of the external element, so that the second contact portion 120 presses against the electrode of the external element, thereby forming a stable electrical connection between the second contact portion 120 and the electrode of the external element. When the second contact portion 120 is disconnected from the electrode of the external element, the compressive force from the electrode of the external element disappears. Due to its inherent resilience, the elastic arm 130 drives the second contact portion 120 to continue moving towards the electrode of the external element, thereby returning the second contact portion 120 to its initial position.

[0089] It should be noted that, in this embodiment, the perpendicularity of the extension direction of the elastic arm 130 to the orientation of the contact surface 121 means that when the contact surface 121 of the second contact portion 120 just makes contact with the electrode of the external element and has not yet moved, the force direction of the contact surface 121 is perpendicular to the extension direction of the elastic arm 130. When the second contact portion 120 moves the elastic arm 130 away from the electrode of the external element due to the squeezing force of the electrode of the external element, the force direction of the contact surface 121 will change during this process, but the force direction of the contact surface 121 will always be set at an angle to the extension direction of the elastic arm 130. This angle can be acute or obtuse. Alternatively, when the second contact portion 120 moves the elastic arm 130 away from the electrode of the external element due to the squeezing force of the electrode of the external element, the direction of one component of the squeezing force on the contact surface 121 will always be perpendicular to the extension direction of the elastic arm 130.

[0090] The internal components of the device for an aerosol supply system provided in this application embodiment include one of an atomizer and a battery assembly, and the external components include the other of an atomizer and a battery assembly.

[0091] In one specific embodiment, the internal components of the device for an aerosol supply system provided in this application include an atomizer, an electrode structure electrically connected to the atomizer, and an external component including a battery assembly, the electrodes of which are connected to the contact surface 121 of the second contact portion 120 to form an electrical connection.

[0092] In another specific embodiment, the internal components of the device for an aerosol supply system provided in this application include a battery assembly, an electrode structure 100 electrically connected to the battery assembly, and an external component including an atomizer, the electrodes of which are connected to the contact surface 121 of the second contact portion 120 to form an electrical connection.

[0093] The following description uses the internal components of the device used in the aerosol supply system, including the atomizer 300, and the external components, including the battery assembly 400, as examples to illustrate the solution of this application.

[0094] It is understood that the electrode structure 100 in this application includes two electrodes. The first contact portion 110 of one electrode structure 100 is connected to the positive electrode of the atomizer 300, and the second contact portion 120 is connected to the positive electrode of the battery assembly 400. The first contact portion 110 of the other electrode structure 100 is connected to the negative electrode of the atomizer 300, and the second contact portion 120 is connected to the negative electrode of the battery assembly 400.

[0095] In some specific embodiments, the elastic arm 130 extends laterally along the device, and the contact surface 121 faces longitudinally towards the device, such as... Figure 3 As shown.

[0096] In some other specific embodiments, the resilient arm 130 extends longitudinally along the device, and the contact surface 121 faces laterally toward the device (not shown).

[0097] It should be noted that the longitudinal direction in this application can be the height direction of the device (i.e., Figures 1 to 3 In some embodiments, the longitudinal length of the device is greater than its transverse length (i.e., the Y direction). Figures 1 to 3 In some cases, the longitudinal length (in the X direction) is longer than the transverse length, for example, in one type of pen-type aerosol supply device. In alternative embodiments, the longitudinal length of the device is shorter than the transverse length, for example, in one type of cartridge-type aerosol supply device, the longitudinal length is shorter than the transverse length.

[0098] In some specific embodiments, the device is cylindrical in shape, and the lateral direction can be its radial direction. The following description uses the example of the elastic arm 130 extending laterally along the device and the contact surface 121 facing longitudinally towards the device to illustrate the solution of this application.

[0099] Further reference Figure 4 As shown in the embodiment of this application, the first contact portion 110 and the second contact portion 120 are respectively located at both ends of the elastic arm 130 in the extending direction. Preferably, the first contact portion 110 and the second contact portion 120 are respectively located at the two ends furthest apart in the extending direction of the elastic arm 130, so that the elastic arm 130 has a longer length in its extending direction within the limited space between the first contact portion 110 and the second contact portion 120, thereby increasing the bending deformation of the elastic arm and improving its elastic deformation capacity.

[0100] In some specific embodiments, the second contact portion 120 can move within a stroke range of 0.1 to 2 mm under the action of the elastic arm 130. For example, 0.1 mm, 0.2 mm, 0.5 mm, 1 mm, 1.5 mm, 1.7 mm, and 2 mm, etc.

[0101] In some specific embodiments, the clamping force of the second contact portion pressing against the electrode of the external element is any value between 0.1 and 5 N. For example, the clamping force of the second contact portion pressing against the electrode of the external element can be 0.1 N, 0.2 N, 0.5 N, 1 N, 1.5 N, 2 N, 2.5 N, 3 N, 4 N, and 5 N, etc.

[0102] Further reference Figure 4 As shown, in some specific embodiments, the elastic arm 130 includes at least one bent portion 131. Configuring the elastic arm 130 to include at least one bent portion 131 maximizes its length in its extending direction within a limited space, thereby increasing the amount of bending deformation and improving its elastic deformation capacity. It should be noted that the specific shape of the bent portion 131 is not limited in the embodiments of this application; it can be set according to actual product requirements without departing from the inventive concept of this application.

[0103] As an illustrative and not limiting description, the bend 131 includes at least one of an arc-shaped structure, an S-shaped structure, a V-shaped structure, a U-shaped structure, an Ω-shaped structure, or a spiral structure.

[0104] In some specific embodiments, the elastic arm is made of at least one of the following: copper alloy (such as phosphor bronze, beryllium copper, etc.), steel (such as stainless steel, spring steel, etc.), titanium alloy (such as nickel titanium alloy, etc.), silver alloy (such as silver copper alloy, silver nickel alloy, etc.), and aluminum alloy.

[0105] In some specific embodiments, the second contact portion 120 has a sheet-like structure, which refers to a special design where the second contact portion 120 adopts a flat, thin sheet-like structure. For example, the second contact portion 120 may be a rectangular or circular sheet. It is understood that configuring the second contact portion 120 as a sheet-like structure provides a larger contact area compared to a traditional needle-like contact portion, thereby facilitating the electrical connection between the electrodes of external components and the second contact portion 120.

[0106] In some specific embodiments, the material of the second contact portion is at least one of copper alloy (such as phosphor bronze, beryllium copper, etc.), steel (such as stainless steel, spring steel, etc.), titanium alloy (such as nickel titanium alloy, etc.), silver alloy (such as silver copper alloy, silver nickel alloy, etc.) and aluminum alloy.

[0107] It should be noted that the shape of the first contact portion 110 is not specifically limited in this embodiment, as long as the first contact portion 110 can form an electrical connection with the internal component (such as an atomizer). For example, as an exemplary rather than restrictive illustration, the first contact portion 110 in this embodiment can be a columnar structure or a wire. The electrical connection between the first contact portion 110 and the internal component can be achieved by snap-fit ​​connection, welding, or other methods.

[0108] It should be noted that, in this embodiment, the extension direction of the first contact portion 110 is not specifically limited. Without departing from the inventive concept of this application, the extension direction of the first contact portion 110 can be set according to actual product requirements. In some specific embodiments, the extension direction of the first contact portion 110 is set at an angle to the extension direction of the elastic arm 130, and the angle can be any value between 0 and 360°.

[0109] In some specific embodiments, the resilient arm 130 is located inside the device, and at least a portion of the contact surface 121 is exposed to the outside of the device. By confining the resilient arm 130 inside the device, contamination can be avoided, thus improving the level of protection. Exposing at least a portion of the contact surface 121 to the outside of the device allows for connection to electrodes of external components, thereby forming an electrical connection between them.

[0110] It is understood that the specific composition of the atomizer 300 is not limited in the embodiments of this application, and any known atomizer can be used in this application without departing from the inventive concept of this application. (See also...) Figure 5As shown, as a preferred example, the atomizer 300 in this embodiment includes a heater (not shown), an atomizing chamber (not shown) for housing the heater, a first support 310 and a second support 320 for fixing the heater, a first seal 330, a silicone element 340, and an oil guide 350. The heater (not shown) abuts against the oil guide 350 and is engaged together between the first support 310 and the second support 320. Preferably, the heater includes a ceramic heater. The heater is electrically connected to the first contact portion 110. The silicone element 340 abuts against the heater and prevents aerosol-generating materials on the heater from dripping.

[0111] Further reference Figures 1 to 3 As shown in the embodiments of this application, the device for an aerosol supply system further includes a liquid storage tank 500, a leak-proof structure 600, a cap 700, and a nozzle 800. The liquid storage tank 500 is configured to contain aerosol generating materials. It is understood that the specific structure of the liquid storage tank 500 is not limited in this application embodiment; any known liquid storage tank applicable to an aerosol supply system can be used in this application without departing from the inventive concept of this application. One end of the first sealing member 330 near the liquid storage tank 500 is sealed to the outlet of the liquid storage tank 500 to prevent leakage of the aerosol generating materials in the liquid storage tank 500. Simultaneously, the first sealing member 330 has an inlet 331 so that the liquid aerosol generating materials stored in the liquid storage tank 500 enter the atomization chamber through the inlet 331 and are heated by the heater to generate aerosol for the user to inhale.

[0112] Reference Figure 6 As shown, in some specific embodiments, the leak-proof structure 600 includes a fixing member 610, a third support 620, a liquid-absorbing member 630, and a second sealing member 640. The third support 620 is configured to form a leak-proof cavity 621, which is adjacent to the atomizing cavity (not shown) and located upstream of the atomizing cavity along the airflow direction. The liquid-absorbing member 630 is configured to be located within the leak-proof cavity 621. The second sealing member 640 is disposed on top of the third support 620 and covers the opening of the leak-proof cavity 621. The second sealing member 640 has an opening 641 that connects the leak-proof cavity 621 to the atomizing cavity. In specific implementations, the second sealing member 640 and the third support 620 are interference-fitted. The fixing member 610 is configured to form a receiving cavity, within which the third support 620, the liquid-absorbing member 630, and the second sealing member 640 are all disposed.

[0113] Understandably, when the aerosol generated in the atomizing chamber cools and produces condensate, the liquid suction component 630 set in the leak-proof chamber 621 absorbs the condensate to prevent the condensate from accumulating in the atomizing chamber and being sucked in by the user along with the aerosol during suction, thus affecting the user's suction experience. At the same time, it can also prevent the condensate from contacting components such as the battery, avoiding damage to the battery and other components.

[0114] Further reference Figure 6 As shown, the second seal 640 is also provided with an electrode hole 642, and the end of the first contact portion 110 away from the elastic arm 130 passes through the electrode hole 642 and is electrically connected to the heater of the atomizer 300.

[0115] A suction nozzle 800 is configured to be located at one end of a liquid reservoir 500 for use in suction. A cap 700 is configured to cover the suction nozzle 800 when the device is not in use, on the one hand to prevent the suction nozzle 800 from being contaminated, and on the other hand to prevent aerosol-generating materials from leaking out of the suction nozzle 800.

[0116] It is understood that the specific composition of the battery assembly 400 is not limited in the embodiments of this application. Any known battery assembly can be used in this application without departing from the inventive concept of this application. (See also...) Figure 7 As shown, as a preferred example, the battery assembly 400 in this application embodiment may include a battery cell 410, a battery casing 420 covering the battery cell 410, a control circuit board 430 electrically connected to the battery cell 410, a battery bracket 440 accommodating the battery cell 410, a battery bottom cover 450, and electrodes 460 of the battery assembly, etc., which will not be described in detail here.

[0117] In some specific embodiments, the battery casing 420 is integrally formed with the device casing 200;

[0118] In some other specific embodiments, the battery housing 420 and the device housing 200 are two separate parts, which are connected together by means of snaps, threads or adhesives.
