Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and particularly to aerosol generation apparatus. Background Technology

[0002] An aerosol generating device is a device that atomizes an aerosol generating matrix to form an aerosol. In some exemplary prior art, an aerosol generating device includes an atomizing component, a rechargeable power supply electrically connected to the atomizing component, and a power switch for controlling the power output of the power supply to the atomizing component. It also includes a charging interface electrically connected to the rechargeable power supply, which can be electrically connected to an external power source (such as AC power or a power bank) via a charger, thereby allowing the external power source to charge the rechargeable power supply inside the aerosol generating device. To prevent users from simultaneously inhaling and charging the aerosol generating device, the aerosol generating device also includes a shield. When the shield blocks the charging interface, the air inlet of the aerosol generating device is exposed, allowing the aerosol generating device to be inhaled.

[0003] However, the shielding components and power switch occupy a large area of ​​the aerosol generating device surface, resulting in poor surface uniformity. Utility Model Content

[0004] This application provides an aerosol generating device with good surface uniformity.

[0005] Some embodiments of this application provide an aerosol generating apparatus, the aerosol generating apparatus comprising:

[0006] The main body includes an atomizing component for generating aerosols from an aerosol generating matrix and a power supply electrically connected to the atomizing component to provide power to the atomizing component;

[0007] The base includes a charging interface electrically connected to the power source and one or more air inlets fluidly communicating with the atomizing component;

[0008] An interactive switch, disposed on the base, and configured to control the power output of the power supply; and

[0009] A cover includes a first through-hole in which at least a portion of the interactive switch is exposed; and the cover is configured to be movably disposed on the base and, when in a first position, to cover all the air inlets and fully expose the charging interface, and, when in a second position, to cover at least a portion of the charging interface and expose at least one of the air inlets.

[0010] As an example, the aerosol generating device further includes a nozzle assembly with an air intake, the nozzle assembly being disposed at the proximal end of the main body, and the air intake being in fluid communication with the atomizing component;

[0011] The base, the interactive switch, and the shielding cover are located at the far end of the main body.

[0012] As an example, the cover includes a shielding portion, a second through hole, and a third through hole independent of the second through hole; when the cover is in the first position, the charging interface is fully exposed through the second through hole, and the shielding portion shields all the air intake holes; when the cover is in the second position, the shielding portion shields at least a portion of the charging interface, and M of the air intake holes are exposed through the third through hole, where M is an integer greater than 0.

[0013] As an example, the air intake has multiple vents, the cover is configured to be movable relative to the base to a third position, and when the cover is in the third position, the cover covers at least a portion of the charging interface, and N air intakes are exposed through the third through-hole, where N is an integer greater than M.

[0014] As an example, the aerosol generating device also includes a first indicator light disposed on the base and a second indicator light disposed on the base;

[0015] The first indicator light is configured to emit light when the charging interface is being charged, and the light emitted when the cover is in the first position is exposed in the second or third through hole;

[0016] The second signal light is configured to emit light when the aerosol generating device is drawn in, and the light emitted when the shield is in the second position is exposed in the second or third through hole.

[0017] As an example, the base also includes a support base and a circuit board electrically connected to the power source, the shield being movably disposed on the support base, and the support base being located between the circuit board and the shield;

[0018] Both the first signal light and the second signal light are electrically connected to the circuit board and are both mounted on the circuit board;

[0019] The support base is provided with a first light guide post and a second light guide post. The first light guide post is set to the first signal light to guide the light emitted by the first signal light, and the second light guide post is set to the second signal light to guide the light emitted by the second signal light.

[0020] As an example, the cover also includes an operating part disposed on the cover portion, the operating part being configured for user operation to drive the cover to move relative to the base, the second through hole and the third through hole being located on opposite sides of the operating part.

[0021] As an example, the base includes a first damping part, and the cover includes a second damping part. When the cover is in the first position or the second position, the first damping part and the second damping part interfere with each other to prevent the cover from moving relative to the base.

[0022] As an example, the base includes a flexible seat and a support seat that supports the flexible seat, the air inlet is disposed on the support seat, and the flexible seat is provided with a detection hole;

[0023] The aerosol generating device further includes a suction detector for detecting suction. The suction detector is interference-fitted into the flexible seat, such that the detection surface of the suction detector is airtightly isolated from its control surface. The detection hole is fluidly connected to the detection surface of the suction detector and the air inlet.

[0024] The first damping part is a component of the flexible seat.

[0025] As an example, the flexible seat is provided with an air intake channel, which fluidly communicates the atomizing component and the air intake hole; the main body includes a shell, the flexible seat is located in the shell, and forms an annular sealing connection with the shell.

[0026] As an example, the shielding cover is movably disposed on the support base, and the support base is located between the flexible seat and the shielding portion of the shielding cover;

[0027] The support base has a fourth through hole, and the cover includes an extension arm that connects to the cover portion. The second damping portion is disposed on the end of the extension arm opposite to the cover portion, and at least a portion of the extension arm is movably located in the fourth through hole.

[0028] As an example, the fourth through hole is provided corresponding to the first through hole, and at least a portion of the interactive switch is located in the fourth through hole.

[0029] As an example, the support base includes a first limiting part and a second limiting part disposed in the fourth through hole, and the extension arm is movably disposed between the first limiting part and the second limiting part.

[0030] As an example, the base includes a support seat connected to the main body, the support seat having a track, the cover including a connecting portion and an anti-retraction portion disposed on the connecting portion, the connecting portion being slidably connected to the track, and the anti-retraction portion being fastened to the support seat to prevent the cover from separating from the support seat.

[0031] As an example, the feature is that the cover is rotatably disposed on the base, and the cover is configured to rotate about the interactive switch.

[0032] In the aforementioned aerosol generating device, the base includes a charging interface electrically connected to a power source, and one or more air inlets. A cover for shielding the charging interface has a first through hole. An interactive switch is mounted on the base, with at least a portion of the switch exposed in the first through hole. This reduces the total area occupied by the cover and the interactive switch, resulting in a more uniform surface finish for the aerosol generating device and enhancing its aesthetic appeal.

[0053] Please refer to Figures 1-6 This application provides an embodiment of an aerosol generating device 100, which includes a main body 1, a base 2, an interactive switch 4, and a shielding cover 3.

[0054] The main body 1 includes an atomizing component 12 for generating aerosol and a power supply 11 electrically connected to the atomizing component 12 to provide power to the atomizing component 12.

[0055] The power source 11 can be any suitable rechargeable power source, thus enabling it to be reused repeatedly.

[0056] As used herein, the term "aerosol-generating matrix" refers to a matrix capable of releasing volatile substances to form inhalable aerosols. The aerosol-generating matrix may include tobacco-containing materials containing volatile tobacco aroma compounds that are released from the matrix upon heating. Specifically, the aerosol-generating matrix may be a tobacco-containing aerosol-generating matrix.

[0057] In some embodiments, the aerosol generating matrix includes a liquid matrix. The liquid matrix may comprise a liquid containing tobacco-containing substances with volatile tobacco aroma components, or it may be a liquid containing non-tobacco substances. The liquid matrix may contain water, pharmaceutical solutions, solvents, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures, etc. Fragrances may include, but are not limited to, areca nut extract, menthol, peppermint, spearmint oil, various fruit flavoring components, etc. Flavorings may contain ingredients that can provide the user with various fragrances or flavors. Vitamin mixtures may be mixtures containing at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but are not limited to these. Based on the different properties of the liquid matrix, aerosol generating devices can be used in different fields, such as medical and electronic aerosol atomization.

[0058] In some embodiments, the aerosol generating matrix includes a liquid matrix, and the atomizing component 12 includes an ultrasonic atomizing component that uses ultrasound to atomize the liquid matrix to form an aerosol.

[0059] In some embodiments, the aerosol generating matrix includes a liquid matrix, and the atomizing assembly 12 includes a liquid guiding element and a heating element. The liquid guiding element is capable of adsorbing the liquid matrix and guiding it into the atomization range of the heating element. The liquid guiding element may be made of a material having capillary channels or pores, such as hard or rigid capillary structures like fiber cotton, porous ceramic bodies, fiberglass ropes, porous glass ceramics, or porous glass. The heating element can release heat to vaporize the liquid matrix when an electric current flows through it.

[0060] In some embodiments, the aerosol generating matrix includes a solid matrix. The aerosol generating matrix may include one or more of the following: powder, granules, pellets, flakes, strips, bands, or sheets, containing one or more of herbaceous plant leaves, tobacco leaves, tobacco vein fragments, reconstituted tobacco, homogenized tobacco, extruded tobacco, and expanded tobacco.

[0061] In some embodiments, the aerosol generating matrix includes a solid matrix, and the atomizing component 12 includes an internal heating element, an external heating element, and / or an air heating element.

[0062] As used herein, the term "external heating element" refers to a heating element positioned outside the aerosol generating matrix when the aerosol generating matrix is ​​assembled in the aerosol generating apparatus. As used herein, the term "internal heating element" refers to a heating element positioned at least partially within the aerosol generating matrix when the aerosol generating matrix is ​​assembled in the aerosol generating apparatus. As used herein, the term "air heating element" refers to a heating element used to heat air in an airflow channel that enters the aerosol generating matrix. The air heating element heats the air flowing through the airflow channel to a high temperature, which then enters the aerosol generating matrix and exchanges heat with the aerosol generating matrix, thereby heating and baking the aerosol generating matrix.

[0063] Heating elements may include resistance heating elements, electromagnetic heating elements, and / or infrared heating elements.

[0064] Resistance heating elements generate Joule heat and can primarily heat the aerosol-forming matrix via heat conduction. Resistance heating elements comprise resistive materials, suitable resistive materials including, but not limited to: semiconductors, such as doped ceramics, conductive ceramics (e.g., molybdenum disilicide), carbon, graphite, metals, metal alloys, and composite materials made of ceramic and metallic materials. Such composite materials may include doped or undoped ceramics. Examples of suitable doped ceramics include doped silicon carbide. Examples of suitable metals include titanium, zirconium, tantalum, and platinum group metals. Examples of suitable metal alloys include stainless steel, constantan, nickel-containing alloys, cobalt-containing alloys, chromium-containing alloys, aluminum-containing alloys, titanium-containing alloys, zirconium-containing alloys, hafnium-containing alloys, niobium-containing alloys, molybdenum-containing alloys, tantalum-containing alloys, tungsten-containing alloys, tin-containing alloys, gallium-containing alloys, manganese-containing alloys, and iron-containing alloys, as well as nickel-, iron-, and cobalt-based superalloys, stainless steel, iron-aluminum-based alloys, and iron-manganese-aluminum-based alloys.

[0065] Electromagnetic heating elements include a sensing element. As used herein, the term "sensor" refers to a material capable of converting electromagnetic energy into heat. When located within a changing electromagnetic field, eddy currents induced in the sensing element cause heating. In such embodiments, the sensing element is designed to engage with an aerosol generating device including a magnetic field generator. The magnetic field generator generates a changing magnetic field to heat the sensing element located within the changing magnetic field. In use, the sensing element is located within the changing magnetic field generated by the magnetic field generator. The magnetic field generator is electrically connected to a power supply assembly that provides current to the magnetic field generator to produce the changing magnetic field. The magnetic field generator may include one or more induction coils that generate the changing magnetic field, and the one or more induction coils may surround the sensing element. In some embodiments, the aerosol generating device is capable of generating a changing magnetic field between 1 and 30 MHz, for example, between 2 and 10 MHz, for example, between 5 and 7 MHz. In some embodiments, the aerosol generating device is capable of generating a changing magnetic field with a field strength (H-field) between 1 and 5 kA / m, for example, between 2 and 3 kA / m, for example, about 2.5 kA / m.

[0066] The receptor may include a metal or carbon. In some embodiments, the receptor may include a ferromagnetic material, such as ferrite, ferromagnetic steel, or stainless steel. In some embodiments, the receptor includes a nickel-iron alloy. In some embodiments, the receptor includes 400 series stainless steel, which includes grade 410, 420, or 430 stainless steel.

[0067] Infrared heating elements can primarily utilize thermal radiation to heat the aerosol-generating matrix. The infrared heating element may include an infrared electrothermal coating, which, when excited or energized, generates heat energy, thereby producing infrared radiation of a specific wavelength, such as far-infrared radiation of 1.5μm to 400μm, preferably far-infrared radiation of 8μm to 15μm.

[0068] The main body 1 may also include a housing 13, and the atomizing component 12 and the power supply 11 may be disposed in the housing 13.

[0069] Please refer to Figures 2-7 The base 2 includes a charging interface 21 electrically connected to the power supply 11 and one or more air inlets 221 fluidly communicating with the atomizing component 12.

[0070] The charging port 21 can be a USB port, which can be compatible with the plug of a charger or data cable. An external power source (mains power or a portable power bank such as a power bank) can charge the rechargeable power source 11 inside the aerosol generating device 100 by electrically connecting to the charging port 21.

[0071] The air inlet 221 is used to guide outside air into the interior of the aerosol generating device 100, so that the air can combine with the volatile substances generated by the atomizing component 12 to form an aerosol.

[0072] The interactive switch 4 can be operated by the user to achieve human-computer interaction. More specifically, the interactive switch 4 is electrically connected to the power supply 11, and the user can control the power output of the power supply 11 by operating the interactive switch 4. For example, the interactive switch 4 can be used to control the aerosol generating device 100 to turn on and off. For example, the interactive switch 4 can be used to control the working power or working mode of the atomizing component 12.

[0073] Interactive switches 4 include, but are not limited to: micro switches, push-button switches, slide switches, or touch screens.

[0074] You can refer to Figures 2-5 The cover 3 is configured to be movably disposed on the base 2, such that the cover 3 can be moved to at least a first position and a second position on the base 2.

[0075] Please refer to Figure 2 When the cover 3 is in the first position, the cover 3 blocks all air inlets 221, so that outside air can hardly enter the atomizing component 12 through the air inlets 221, thereby preventing the atomizing component 12 in the aerosol generating device 100 from working and preventing the aerosol generating device 100 from generating aerosol; at the same time, the cover 3 does not block the charging interface 21, so the charging interface 21 is completely exposed, so the plug can be inserted into the charging interface 21, thereby charging the power supply 11 inside the aerosol generating device 100.

[0076] Please refer to Figure 3 When the cover 3 is in the second position, the cover 3 covers at least a portion of the charging interface 21, so that the plug cannot be inserted into the charging interface 21, thereby preventing the power supply 11 inside the aerosol generating device 100 from being charged; at the same time, at least one air inlet 221 is not covered by the cover 3, so that at least one air inlet 221 is exposed, and then outside air can enter the aerosol generating device 100 through the air inlet 221 and flow to the atomizing component 12, so that the atomizing component 12 in the aerosol generating device 100 can work and generate aerosol.

[0077] In other words, when the cover 3 is in the first position, the charging interface 21 is fully exposed, allowing the plug to be inserted, thus enabling the power supply 11 in the aerosol generating device 100 to be charged. However, because sufficient outside air cannot flow to the atomizing component 12, the aerosol generating device 100 cannot generate aerosols. When the cover 3 is in the second position, sufficient outside air can flow to the atomizing component 12, enabling the aerosol generating device 100 to generate aerosols. However, because at least part of the charging interface 21 is blocked, the plug cannot be inserted into the charging interface 21, thus preventing the power supply 11 in the aerosol generating device 100 from being charged.

[0078] Furthermore, you can refer to Figure 2 and 7 The shielding cover 3 has a first through hole 31, and the interactive switch 4 is mounted on the base 2, with at least a portion of the interactive switch 4 exposed in the first through hole 31, allowing the interactive switch 4 to be touched and operated by the user. Integrating the base 2, the interactive switch 4, and the shielding cover 3 allows for a more concentrated exposure of the interactive switch 4 and the shielding cover 3 on the surface of the aerosol generating device 100, while reducing the total area occupied by the interactive switch 4 and the shielding cover 3 on the surface of the aerosol generating device 100, thereby improving the uniformity and aesthetics of the surface of the aerosol generating device 100.

[0079] In some embodiments, reference may be made to Figure 1 The aerosol generating device 100 also includes a mouthpiece assembly 5 having an air intake 51, at least a portion of which can be held in the mouth of a user, and when the mouthpiece assembly 5 is held in the mouth of a user, the air intake 51 faces the user's oral cavity.

[0080] The nozzle assembly 5 is located at the near end of the main body 1, and the air inlet 51 is in fluid communication with the atomizing assembly 12. The user draws in the aerosol generated by the aerosol generating matrix by drawing in the nozzle assembly 5.

[0081] The base 2, the interactive switch 4, and the shielding cover 3 are located at the far end of the main body 1. (The remaining text appears to be incomplete and possibly contains errors.) Figure 1 In the illustrated embodiment, the air intake 51 is located at the top of the aerosol generating device 100, while the base 2, the interactive switch 4, and the shielding cover 3 are located at the bottom of the aerosol generating device 100. This ensures that the side surface of the aerosol generating device 100 has good consistency and integrity. Moreover, when the aerosol generating device 100 is in normal placement and when the user is inhaling the aerosol generating device 100, the bottom of the aerosol generating device 100 is a visually neglected or difficult-to-observe area. Therefore, placing the base 2, the interactive switch 4, and the shielding cover 3 at the far end of the main body 1 or at the bottom of the aerosol generating device 100 can further improve the overall consistency and aesthetics of the aerosol generating device 100.

[0082] In some embodiments, reference may be made to Figures 2-5 The cover 3 is rotatably mounted on the base 2, and is configured to rotate around the interactive switch 4. Thus, by rotating the cover 3, it can rotate back and forth between a first position and a second position. Of course, the cover 3 can also be configured to rotate only in one direction, such as only clockwise or only counterclockwise.

[0083] In some embodiments, reference may be made to Figure 6 and Figure 7 The base 2 includes a support 22 connected to the main body 1, and a track 222 is provided on the support 22. The cover 3 includes a covering part 32 for covering the charging interface 21 and / or the air inlet 221, and also includes a connecting part 33 and an anti-retraction part 34. The connecting part 33 is slidably connected to the track 222, so that the cover 3 can move relative to the support 22. The anti-retraction part 34 is fastened to the support 22 to prevent the cover 3 from separating from the support 22.

[0084] The anti-recoil part 34 can be provided on the connecting part 33, so that the anti-recoil part 34 and the blocking part 32 can be located on opposite sides of the track 222. In such cases... Figures 6-8 In the embodiment shown, the shielding part 32 and the connecting part 33 can be arranged approximately perpendicularly, the anti-retraction part 34 and the connecting part 33 are approximately hook-shaped after being joined, the track 222 includes a groove that passes through the support base 22, the connecting part 33 is located in the groove and the anti-retraction part 34 is fastened to the edge of the groove.

[0085] In some embodiments, reference may be made to Figure 2 , Figure 3 and Figure 7 The cover 3 also includes a second through hole 35 and a third through hole 36 independent of the second through hole 35.

[0086] When the shielding cover 3 is in the first position, the charging interface 21 is fully exposed through the second through hole 35, while the shielding part 32 blocks all air inlets 221, so that the power supply 11 in the aerosol generating device 100 can be charged, but the aerosol generating device 100 cannot generate aerosols.

[0087] When the cover 3 is in the second position, the cover 32 blocks at least a portion of the charging interface 21, while M air inlets 221 are exposed through the third through-hole 36, where M is an integer greater than 0, for example, M can be equal to 1. Thus, the aerosol generating device 100 can generate aerosols, and the user can inhale the aerosol generating device 100, but cannot charge the power supply 11 in the aerosol generating device 100.

[0088] The shielding cover 3 is provided with a second through hole 35 and a third through hole 36 that are spaced apart from each other. This can ensure that the shielding cover 3 has a stable structure and reduce the amount of material used to make the shielding cover 3, thereby reducing costs.

[0089] In some embodiments, reference may be made to Figure 4 The air inlet 221 has multiple air inlets, and the cover 3 is configured to move relative to the base 2 to a third position. When the cover 3 is in the third position, the cover portion 32 covers at least a portion of the charging interface 21, and N air inlets 221 are exposed through the third through hole 36, where N is an integer greater than M. For example, when M equals 1, N can equal 2.

[0090] When the shielding cover 3 is in the third position, the shielding part 32 shields at least a portion of the charging interface 21, so that the plug cannot be inserted into the charging interface 21, thereby preventing the power supply 11 inside the aerosol generating device 100 from being charged; at the same time, at least one air inlet 221 is not shielded by the shielding part 32, so that N air inlets 221 are exposed, and then outside air can enter the interior of the aerosol generating device 100 through the N air inlets 221 and flow to the atomizing component 12, so that the atomizing component 12 in the aerosol generating device 100 can work and generate aerosol.

[0091] Compared to the second position, the number of air inlets 221 exposed when the shield 3 is in the third position is greater, allowing more air to enter the aerosol generating device 100 and flow to the atomizing component 12 per unit time during suction. Therefore, the suction resistance of the aerosol generating device 100 is lower when the shield 3 is in the third position compared to the second position.

[0092] Compared to the second position, when the cover 3 is in the third position, the area of ​​the cover 32 covering the charging port 21 can be larger.

[0093] In some embodiments, the second position is disposed between the first position and the third position. The cover 3 can move sequentially from the first position to the second position, and then from the second position to the third position. The cover 3 can also move sequentially from the third position to the second position, and then from the second position to the first position. It should be noted that in other embodiments, the third position can be disposed between the first position and the second position.

[0094] Similarly, in some embodiments, reference can be made to Figure 5 The cover 3 is configured to move relative to the base 2 to a fourth position. When the cover 3 is in the fourth position, the cover 3 covers at least a portion of the charging interface 21, while N' air inlets 221 are exposed through the third through hole 36, where N' is an integer greater than N. For example, when N equals 2, N' can equal 3.

[0095] Compared to the third position, the number of air inlets 221 exposed when the shield 3 is in the fourth position is greater, allowing more air to enter the aerosol generating device 100 and flow to the atomizing component 12 per unit time during suction. Therefore, the suction resistance of the aerosol generating device 100 is lower when the shield 3 is in the fourth position compared to the third position.

[0096] Compared to the third position, when the cover 3 is in the fourth position, the area of ​​the cover 32 that blocks the charging port 21 can be larger.

[0097] In some embodiments, the third position is disposed between the second and fourth positions. The cover 3 can move sequentially from the first position to the second position, from the second position to the third position, and then from the third position to the fourth position. The cover 3 can also move sequentially from the fourth position to the third position, from the third position to the second position, and then from the second position to the first position. It should be noted that in other embodiments, the fourth position can be disposed between the third and second positions.

[0098] In some embodiments, the track 222 on the support 22 is arc-shaped or strip-shaped, rather than a closed ring, so that the cover 3 cannot rotate 360° relative to the base 2. Therefore, the cover 3 cannot directly reach the first position from the third position without passing through the second position. Alternatively, the cover 3 cannot directly reach the first position from the fourth position without passing through the third and second positions.

[0099] In some embodiments, reference may be made to Figure 7 The aerosol generating device 100 also includes a first indicator light 251, which is configured to emit light when the charging interface 21 is being charged. The first indicator light 251 may emit light including, but not limited to, a continuous, stable light or a flashing light. The light emitted by the first indicator light 251 may differ when the power supply 11 in the aerosol generating device 100 is fully charged and when the power supply 11 is not fully charged, including but not limited to different colors or different flashing frequencies.

[0100] The first signal light 251 can be installed on the base 2. When the cover 3 is in the first position, the first signal light 251 can be exposed in the second through hole 35 or the third through hole 36, so that the light emitted by the first signal light 251 is not blocked by the cover 32 and can be perceived by the user's vision.

[0101] You can refer to Figure 7The aerosol generating device also includes a second indicator light 252, which is configured to emit light when the aerosol generating device 100 is drawn in. The second indicator light 252 can be mounted on the base 2. When the shielding cover 3 is in the second, third, or fourth position, the second indicator light 252 can be exposed in the second through hole 35 or the third through hole 36, so that the light emitted by the second indicator light 252 is not blocked by the shielding part 32 and can be perceived by the user's vision.

[0102] Furthermore, in such Figure 2 In the illustrated embodiment, when the cover 3 is in the first position, the light emitted by the first signal lamp 251 or the first light-transmitting part 225 is exposed in the second through hole 35, while the second signal lamp 252 or the second light-transmitting part 226 is blocked by the cover 32. When the cover 3 is in the second, third, or fourth position, the light emitted by the second signal lamp 252 or the second light-transmitting part 226 is exposed in the second through hole 35. At this time, the light emitted by the first signal lamp 251 or the first light-transmitting part 225 can be blocked by the cover 32, or the light emitted by the first signal lamp 251 or the first light-transmitting part can also be exposed in the second through hole 35.

[0103] In some embodiments, reference may be made to Figure 6 and Figure 7 The base 2 also includes a support 22 and a circuit board 24 electrically connected to the power supply 11. The shield 3 is movably disposed on the support 22, and the support 22 is located between the circuit board 24 and the shield 3. The first signal light 251 and the second signal light 252 are both electrically connected to the circuit board 24, and both the first signal light 251 and the second signal light 252 are disposed on the circuit board 24.

[0104] You can refer to Figure 7 and Figure 9 The support base 22 is provided with a first light guide post 223, which is provided corresponding to the first signal light 251 to guide the light emitted by the first signal light 251. At the same time, it can also prevent the light emitted by the second signal light 252 from passing through the wall of the first light guide post 223 and entering the interior of the first light guide post 223, and prevent the light emitted by the first signal light 251 from passing through the wall of the first light guide post 223 and exiting the first light guide post 223, which helps to make the light emitted by the first signal light 251 brighter.

[0105] The support base 22 is also provided with a first light-transmitting part 225 corresponding to the first light guide column 223. The light emitted by the first signal lamp 251 passes through the interior of the first light guide column 223 and then shines out from the first light-transmitting part 225.

[0106] You can refer to Figure 7 and Figure 9A second light guide post 224 is provided on the support base 22. The second light guide post 224 is set corresponding to the second signal light 252 to guide the light emitted by the second signal light 252. At the same time, it can also prevent the light emitted by the first signal light 251 from passing through the wall of the second light guide post 224 and entering the interior of the second light guide post 224, and prevent the light emitted by the second signal light 252 from passing through the wall of the second light guide post 224 and exiting the second light guide post 224, which helps to make the light emitted by the second signal light 252 brighter.

[0107] The support base 22 is also provided with a second light-transmitting part 226 corresponding to the second light guide post 224. The light emitted by the second signal lamp 252 passes through the interior of the second light guide post 224 and then shines out from the second light-transmitting part 226.

[0108] The first light-transmitting part 225 and the second light-transmitting part 226 can be of different colors or have different shapes, so that the light emitted by the first signal light 251 and the light emitted by the second signal light 252 are different after they are emitted. In this case, the first signal light 251 and the second signal light 252 can be the same LED light, but are not limited to this.

[0109] In such Figure 7 In the embodiment shown, the first light-transmitting part 225 is lightning-shaped, and the second light-transmitting part 226 is teardrop-shaped.

[0110] In some embodiments, reference may be made to Figures 2-5 The cover 3 also includes an operation part 37 disposed on the cover part 32. The operation part 37 is configured for user operation, thereby driving the cover 3 to move relative to the base 2. The second through hole 35 and the third through hole 36 are located on opposite sides of the operation part 37.

[0111] In some embodiments, reference may be made to Figures 6-8 The base 2 includes a first damping part 231, and the cover 3 includes a second damping part 38. When the cover 3 is in the first position, the second position, the third position, or the fourth position, the first damping part 231 and the second damping part 38 interfere with each other to prevent the cover 3 from moving relative to the base 2, thereby keeping the cover 3 in the first position, the second position, the third position, or the fourth position, and providing a damping feel when driving the cover 3 to move from the current position to the next position.

[0112] When the cover 3 can move to multiple positions relative to the base 2, the first damping part 231 and / or the second damping part 38 have multiple positions.

[0113] In such Figures 6-8In the illustrated embodiment, there is one second damping part 38 and multiple first damping parts 231. The number of the multiple first damping parts 231 is the same as the number of multiple positions in which the cover 3 can be held, and the multiple first damping parts 231 are arranged in a one-to-one correspondence with the multiple positions in which the cover 3 can be held. Thus, when the cover 3 is in different positions, the second damping part 38 interferes with different first damping parts 231 respectively.

[0114] In some embodiments, reference may be made to Figure 6 and Figure 7 The base 2 includes a flexible seat 23, a support seat 22 that can support the flexible seat 23, an air inlet 221 is provided on the support seat 22, and a detection hole 232 is provided on the flexible seat 23; the aerosol generating device 100 also includes a suction detector 6 for detecting suction, the suction detector 6 is interference-fitted into the flexible seat 23, so that the detection surface of the suction detector 6 is airtightly isolated from its control surface, and the detection hole 232 is fluidly connected to the detection surface of the suction detector 6 and the air inlet 221.

[0115] The suction detector 6 is electrically connected to the circuit board 24. When the electrical parameters between the detection surface and the control surface of the suction detector 6 change beyond a threshold, it can be determined that the aerosol generating device 100 is being suctioned. The suction detector 6 can then send a switch signal: the controller on the circuit board 24 can control the power supply 11 to provide power to the second indicator light 252 through the circuit board 24 according to the switch signal, so that the second indicator light 252 lights up; and / or, the controller on the circuit board 24 can control the power supply 11 to provide power to the atomizing component 12 through the circuit board 24 according to the switch signal, so that the atomizing component 12 atomizes the aerosol generating matrix and generates aerosol.

[0116] The detection surface of the suction detector 6 and the air inlet 221 are fluidly connected through the inspection hole 231. When the user draws aerosol from the aerosol generating device 100, the gas near the detection surface enters the air inlet channel 233 through the detection hole 232, and the outside air enters the air inlet channel 223 through the air inlet 221. Then, the gas flows into the atomizing component 12 through the air inlet channel 223. This causes the detection surface to vibrate or deform, resulting in a change in the electrical parameters between the detection surface and the control surface of the suction detector 6 that exceeds the threshold.

[0117] When suction stops, outside air flows into the vicinity of the detection surface through the air inlet 221 and the detection hole 232, thereby restoring the detection surface. The power supply 11 then stops providing power to the second indicator light 252 and / or the atomizing assembly 12.

[0118] Users can operate the interactive switch 4 to control the power supply 11 to provide power to the suction detector 6, enabling the suction detector 6 to operate. When the suction detector 6 is operating, it can detect whether the aerosol generating device 100 is being suctioned. Users can also operate the interactive switch 4 to control the power supply 11 to stop providing power to the suction detector 6, enabling it to operate in a non-operating state. For example, users can operate the interactive switch 4 to turn on the aerosol generating device 100, after which the suction detector 6 is in operating mode; users can also operate the interactive switch 4 to turn off the aerosol generating device 100, after which the suction detector 6 is in a non-operating state.

[0119] The flexible seat 23 can be made of elastic but non-breathable materials such as silicone.

[0120] In such Figure 6 and Figure 7 In the embodiment shown, the first damping part 231 is a component of the flexible seat 23.

[0121] In some embodiments, reference may be made to Figure 6 and Figure 7 The shielding cover 3 is movably disposed on the support base 22, and the support base 22 is located between the flexible base 23 and the shielding part 32 of the shielding cover 3. The support base 22 is provided with a fourth through hole 227. The shielding cover 3 includes an extension arm 39 connected to the shielding part 32. A second damping part 38 is disposed on the end of the extension arm 39 opposite to the shielding part 32. At least a portion of the extension arm 39 is movably disposed in the fourth through hole 227. Thus, when the shielding cover 3 moves relative to the base 2, at least a portion of the extension arm 39 moves in the fourth through hole 227. At the same time, the second damping part 38 disposed on the extension arm 39 moves relative to the flexible base 23 and interferes with the flexible base 23.

[0122] In such Figure 7 and Figure 8 In the embodiment shown, the first damping portion 231 includes a recessed portion disposed on the surface of the flexible seat 23, and the second damping portion 38 includes a protrusion disposed at the end of the extension arm 39.

[0123] In some embodiments, the fourth through hole 227 is provided corresponding to the first through hole 31, and at least a portion of the interactive switch 4 is located in the fourth through hole 227.

[0124] The interactive switch 4 may include a switching element 41 disposed on a circuit board 24 and a button 42 at least partially disposed in a fourth through hole. The button 42 is configured to move along the central axis of the fourth through hole 227 when pressed by a user, thereby triggering the switching element 41. A flexible base 23 may elastically support the button 42, so that when the user stops pressing the button 42, the button 42 can be reset by the elastic force provided by the flexible base 23. When the user presses button 42, button 42 can squeeze the corresponding area of ​​flexible seat 23, causing the corresponding area of ​​flexible seat 23 to deform, thereby allowing the corresponding area of ​​flexible seat 23 to touch the switching element 41 on circuit board 24. Thus, when button 42 is pressed, flexible seat 23 touches switching element 41, triggering switching element 41. Alternatively, flexible seat 23 is provided with a fifth through hole 224 corresponding to the fourth through hole 227. When the user presses button 42, a part of button 42 can pass through the fifth through hole 224 to touch switching element 41. Thus, when button 42 is pressed, button 42 can touch switching element 41, thereby triggering switching element 41.

[0125] In some embodiments, reference may be made to Figure 7 and Figure 9 The support base 22 includes a first limiting part 228 and a second limiting part 229 disposed in the fourth through hole 227, and the extension arm 39 is movably disposed between the first limiting part 228 and the second limiting part 229. The first limiting part 228 and the second limiting part 229 are used to limit the movement stroke of the extension arm 39 in the fourth through hole 227, so that the extension arm 39 cannot rotate 360° in the fourth through hole 227, thereby preventing the cover 3 from rotating 360° relative to the base 2.

[0126] Preferably, the angle of rotation of the cover 3 relative to the base 2 is less than or equal to 90°.

[0127] In some embodiments, the charging interface 21 can only be exposed through the second through hole 35, and the air inlet 221 can only be exposed through the third through hole 36. Based on this, the track 222 on the support 22 can be configured such that one end of it is adjacent to the first position; or, the first limiting part 228 or the second limiting part 229 can be configured to be adjacent to the first position.

[0128] In some embodiments, reference may be made to Figure 1 and Figure 7 The flexible seat 23 is provided with an air intake channel 233, which is fluidly connected to the atomizing component 12 and the air intake hole 221. The detection hole 232 is fluidly connected to the air intake hole 221 through the air intake channel 233. The flexible seat 23 is located in the outer shell 13 of the main body 1, and an annular sealing connection is formed between the flexible seat 23 and the outer shell 13, so that the outside air mainly enters the 233 through the air intake hole 221, which helps to improve the detection sensitivity of the suction detector 6.

[0129] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification.
