Description

TECHNICAL FIELD

[0001] The embodiments of the present application relate to the technical field of aerosol generation, in particular to an aerosol generating device. BACKGROUND

[0002] The aerosol generating device is a device capable of generating smoke from a smoking article. In some exemplary prior art, the aerosol generating device comprises a housing in which a smoking article accommodating cavity is arranged, and a heating element for heating the smoking article. The aerosol generating device further comprises a pushing mechanism capable of moving relative to the accommodating cavity, and a bracket in sliding connection with the pushing mechanism to define a sliding track. When the pushing mechanism moves in a predetermined direction, the pushing mechanism can push the smoking article out of the accommodating cavity, thereby facilitating the user to take out the smoking article. After that, the pushing mechanism can be reset. The pushing mechanism is in interference fit with the bracket to ensure that the pushing mechanism can be provided with radial support by the bracket after being reset, so that the pushing mechanism does not shake after being reset.

[0003] However, on the one hand, this will undoubtedly cause greater wear and tear to the pushing mechanism, and after long-term use, the pushing mechanism will inevitably shake after being reset. On the other hand, this will result in greater frictional resistance between the pushing mechanism and the bracket, which will produce a greater resistance during the process in which the user manually drives the pushing mechanism to push the smoking article out of the accommodating cavity. This will result in an undesirable user experience. SUMMARY

[0004] The purpose of the present application is to provide an aerosol generating device capable of reducing the wear and tear on the reset component and the resistance during the process of pushing the aerosol generating article out of the accommodating cavity, and preventing the driving mechanism from shaking after the pushing component is reset to the first position.

[0041] Some embodiments of the present application provide an aerosol generating device, comprising:

Thus, based on the area defined by the proximal end of the inclined surface being smaller than the area defined by the distal end of the inclined surface, there is no contact between the positioning surface and the inner wall of the positioning hole during movement of the pushing assembly from the first position to the second position and during movement of the pushing assembly from the second position to the first position, so as to reduce friction and resistance caused by friction between the positioning surface and the positioning hole. After the pushing assembly is returned to the first position, the positioning portion can be gathered against the inner wall of the positioning hole, so as to effectively prevent the pushing assembly from shaking at the first position.

[0068] Please refer to Figures 1-3 One embodiment of this application provides an aerosol generating apparatus, which is an apparatus capable of generating aerosols from aerosol generating articles.

[0069] In some embodiments, the aerosol generating article includes a solid aerosol forming matrix capable of releasing volatile compounds that can form aerosols when a certain temperature is reached. Aerosols formed by heating a solid aerosol forming matrix may contain fewer known hazardous components than aerosols generated by combustion or pyrolytic degradation of the aerosol forming matrix. In one embodiment, the aerosol generating article is removably coupled to an aerosol generating device. The aerosol generating article may be disposable or reusable.

[0070] Solid aerosol forming matrix may include tobacco-containing materials containing volatile tobacco flavor compounds released from the matrix upon heating. Solid aerosol forming matrix may also include non-tobacco materials. Solid aerosol forming matrix may include both tobacco-containing and non-tobacco-containing materials. When the aerosol forming matrix is ​​a solid aerosol forming matrix, the aerosol-generating article may be a tobacco block, cigarette stick, tobacco rod, or cigar, etc.

[0071] In some embodiments, the aerosol generating article includes a liquid aerosol forming matrix, which may comprise a liquid containing tobacco-containing substances with volatile tobacco aroma components, and may also comprise a liquid containing non-tobacco substances. The liquid aerosol matrix may comprise 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. Aerosol generating devices can be used in various fields, such as medical and electronic aerosol atomization.

[0072] Please refer to Figures 1-3 The aerosol generating device includes a housing assembly 1 and a heating assembly 2 disposed inside the housing assembly 1.

[0073] In some embodiments, the heating assembly 2 includes a receiving cavity 21 for containing an aerosol-generating article and a heating element for providing energy to heat the aerosol-generating article to generate aerosols. The aerosol-generating article is configured to be removable from the receiving cavity 21.

[0074] The housing assembly 1 is provided with an assembly port 11, and one end of the receiving cavity 21 is open and corresponding to the assembly port 11. When the assembly port 11 is open, the aerosol generating article in the receiving cavity 21 can be removed from the aerosol generating device through the assembly port 11 to replace the aerosol generating article. Of course, the aerosol generating article can also pass through the assembly port 11 to enter the receiving cavity 21. When the assembly port 11 is open, the user can also use a brush or other cleaning tools to reach inside the housing assembly 1 to clean the components disposed inside the housing assembly 1.

[0075] The housing assembly 1 may include an annular housing defining the side surface of the aerosol generating device, and may also include a bottom cover 12 connected to one end of the housing and a top cover connected to the opposite end of the housing. The assembly port 11 may be formed on the housing or on the top cover, as shown in the example. Figures 1-3 In the embodiment shown, the assembly port 11 is provided on the bottom cover 12.

[0076] The aerosol generating device may further include a shielding plug 8, which is movably connected to the housing assembly 1: for example, the shielding plug 8 is detachably connected to the housing assembly 1, allowing it to be removed from the housing assembly 1; or, for example, the shielding plug 8 is slidably or rotatably connected to the housing assembly 1, allowing it to remain connected to the housing assembly 1 even after being removed from the mounting port 11. The mounting port 11 is open when the shielding plug 8 is removed. Known detachable connections include, but are not limited to, magnetic connections or snap-fit ​​connections.

[0077] It should be noted that in some embodiments of this application, the heating component 2 and the aerosol generating article are independent products. When the aerosol generating article is removed from the housing component 1, the heating component 2 can remain in the housing component 1.

[0078] In other embodiments, the heating component and the aerosol generating article are joined together, and the heating component is removed from the housing assembly when the aerosol generating article is removed from the housing assembly. For example, the heating component includes a cup body with a receiving cavity disposed therein, and the aerosol generating article is a liquid aerosol forming matrix. The heating element includes an atomizing core capable of absorbing the liquid aerosol forming matrix and atomizing at least a portion of the absorbed liquid aerosol forming matrix to form an aerosol. Alternatively, the heating component includes a housing, with the heating element fixed to or held within the housing. The aerosol generating article includes one or more solid aerosol forming matrices disposed within the housing corresponding to the heating element to obtain heat from the heating element and generate an aerosol.

[0079] When the aerosol generating article includes a fixed aerosol forming matrix, the heating assembly may include a central heating element, a circumferential heating element, and / or an air heating element. Wherein, as used herein, a "central heating element" refers to a heating element located at least partially inside the aerosol generating article when it is engaged in the receiving cavity; a "circumferential heating assembly" refers to a heating element disposed outside the aerosol generating article when it is engaged in the receiving cavity; and an "air heating assembly" refers to a heating assembly disposed upstream of the receiving cavity along the airflow direction for heating air to form hot air, which then flows into the aerosol generating article within the receiving cavity to heat the aerosol generating article.

[0080] In some embodiments, the heating assembly includes a resistance heating element, an infrared heating element, and / or an electromagnetic heating element. Thus, the aerosol-generating article is able to generate aerosols under the action of thermal energy provided by the heating assembly.

[0081] A resistance heating element is a heating element that generates Joule heat when an electric current is applied. 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. Resistance heating elements may include a coating made of the resistive material, or may include a heating wire, heating element, heating coil, or heating mesh.

[0082] The infrared heating element can be an infrared coating. When excited or when it receives an electric current, the infrared coating can radiate infrared rays with a wavelength of 0.75μm to 1000μm, preferably far-infrared rays with a wavelength of 1.5μm to 400μm, and more preferably far-infrared rays with a wavelength of 8μm to 15μm.

[0083] Electromagnetic heating elements include sensors, which are materials capable of converting electromagnetic energy into heat. When located within a changing electromagnetic field, eddy currents induced in the sensors cause heating. In such embodiments, the sensors are 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 sensors located within the changing magnetic field. In use, the sensors are situated 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 these coils may surround the sensors. In one embodiment, the aerosol generating device is capable of generating a changing magnetic field between 1 MHz and 30 MHz, for example, between 2 MHz and 10 MHz, or for example, between 5 MHz and 7 MHz. In one embodiment, the aerosol generating device is capable of generating a magnetic field with a varying field strength (H field) between 15 kA / m and 5 kA / m, for example between 25 kA / m and 3 kA / m, for example about 2.5 kA / m.

[0084] The receptor may include a metal or carbon. In one embodiment, the receptor may include a ferromagnetic material, such as ferrite, ferromagnetic steel, or stainless steel. In one embodiment, the receptor includes a nickel-iron alloy. In one embodiment, the receptor includes 400 series stainless steel, which includes grade 410, 420, or 430 stainless steel.

[0085] In some embodiments, the aerosol generating article includes a sensor, and the heating element in the heating assembly includes a magnetic field generator. When the aerosol generating article is housed in the housing cavity, the sensor in the aerosol generating article is located within the range of fluctuations in the changing magnetic field generated by the magnetic field generator, so that the sensor in the aerosol generating article can generate heat under the action of the electromagnetic energy provided by the heating assembly, thereby causing the aerosol forming matrix to generate aerosols.

[0086] In such Figure 2 and Figure 3 In the illustrated embodiment, the heating assembly 2 includes a tubular body 22 that surrounds at least a portion of the receiving cavity 21, such that the aerosol-generating article is surrounded by the tubular body 22 when it is contained within the receiving cavity 21. The heating element may include the tubular body, enabling it to generate heat and heat the aerosol-generating article. The heating element may be disposed on the tubular body 22; for example, the heating element may include, but is not limited to, a coating applied to the outer surface of the tubular body 22, such that the heat generated, the emitted infrared radiation, or the generated changing magnetic field must penetrate the tubular body 22 to flow to the aerosol-generating article.

[0087] In some embodiments, reference may be made to Figure 2 and Figure 3 The aerosol generating apparatus also includes a positioning member 6 and a pushing component 3. The positioning member 6 is provided with a positioning hole 61. The pushing component 3 includes a positioning part 321 and is configured to move relative to the heating component 2 between a first position and a second position. During the process of the pushing component 3 moving from the first position to the second position, the pushing component 3 moves toward the assembly port 11 to push at least a portion of the aerosol generated article out of the receiving cavity 21.

[0088] At least one of the inner wall of the positioning hole 61 and the outer surface of the positioning part 321 includes an inclined surface, the area defined by the proximal end of the inclined surface being smaller than the area defined by its distal end. During at least a portion of the process of the pushing component 3 resetting to the first position, the positioning part 321 moves within the positioning hole 61 along a direction from the distal end to the proximal end of the positioning hole 61, and abuts against the inner wall of the positioning hole 61 when the pushing component 3 is in the first position. It should be noted that the direction from the distal end to the proximal end of the positioning hole 61 refers to the direction of movement, not a limitation on the start and end points of the travel.

[0089] When the inner wall of the positioning hole 61 has the aforementioned inclined surface, the area defined by the proximal end of the positioning hole 61 is smaller than the area defined by its distal end, or the area enclosed by the inner wall of the proximal end of the positioning hole 61 is smaller than the area enclosed by the inner wall of its distal end. The positioning hole 61 can be approximately frustum-shaped or approximately truncated pyramidal. The positioning hole 61 can be a blind hole or a through hole penetrating the positioning member 6. The positioning hole 61 can be a component of a through hole formed on the positioning member 6; for example, the through hole may consist of two parts with different hole shapes, and the positioning hole 61 is one of those parts.

[0090] When the outer surface of the positioning part 321 has the aforementioned inclined surface, the area defined by the proximal end of the positioning part 321 is smaller than the area defined by its distal end, or the area enclosed by the outer surface of the proximal end of the positioning part 321 is smaller than the area enclosed by the outer surface of its distal end. The shape enclosed by the outer surface of the positioning part 321 can be approximately frustum-shaped or approximately truncated pyramidal.

[0091] In such Figure 2 and Figure 5 In the illustrated embodiment, both the inner wall of the positioning hole 61 and the outer surface of the positioning part 321 include inclined surfaces, and the areas defined by the proximal ends of the inner wall of the positioning hole 61 and the outer surface of the positioning part 321 are smaller than the areas defined by their distal ends. Preferably, the inclined surfaces on the inner wall of the positioning hole 61 and the inclined surfaces on the outer surface of the positioning part 321 are arranged parallel to each other or have the same inclination, so that when the pushing component 3 is in the first position, the inner wall of the positioning hole 61 can contact the outer surface of the positioning part 321, thereby increasing the contact area between the positioning hole 61 and the positioning surface 321. This helps to prevent the pushing component 3 from shaking in the first position and also helps to reduce wear on the pushing component 3 and / or the positioning member 6.

[0092] In some embodiments, reference may be made to Figure 2 and Figure 3 The aerosol generating device also includes a reset component 4, which interferes with the pushing component 3 to drive the pushing component 3 to reset to the first position. As an example, see [reference needed]. Figure 2 and Figure 3The reset component 4 includes an elastic element connected to the push component 3. The elastic element continuously undergoes elastic deformation during the movement of the push component relative to the heating component 2. This elastic deformation creates elastic interference between the reset component 4 and the push component 3. This elastic interference supports the push component 3, helping to maintain it in a first position and automatically resetting it back to the first position if it deviates from it. As an example, the reset component 4 includes a first magnetic element, and the push component 3 includes a second magnetic element. The first and second magnetic elements have magnetic attraction or repulsion, causing magnetic interference between the reset component 4 and the push component 3. This magnetic interference acts on the push component 3, helping to maintain it in the first position and automatically resetting it back to the first position if it deviates from it.

[0093] In some embodiments, the pushing component 3 includes an operating part 34 and a first moving member 32 that interferes with the reset component 4. The operating part 34 is configured to be operable by a user and, based on this operation, drives the pushing component 3 to move longitudinally from a first position to a second position, such that the pushing component 3 can move in a generally linear motion during the movement from the first position to the second position. In some embodiments, the direction from the distal end to the proximal end of the positioning hole 61 is substantially consistent with the longitudinal direction.

[0094] The reset component 4 can be disposed inside the housing component 1, thus being hidden. At least a portion of the push component 3 can be disposed inside the housing component 1, thus being hidden; the operating part 34 can be exposed outside the housing component 1, so that the operating part 34 can be operated by the user, for example, the operating part 34 can be pressed by the user, and the user moves the push component 3 from the first position to the second position by pressing the operating part 34. Of course, some operations can also be used to expose the operating part 34 that was originally covered by the housing component 1.

[0095] The positioning element 6 can be disposed adjacent to the operating part 34 to prevent the operating part 34 from shaking.

[0096] Furthermore, the operating part 34 and the first moving member 32 can be located on opposite sides of the positioning member 6. During at least a portion of the movement of the pushing component 3 from the first position to the second position, at least a portion of the operating part 34 can enter the positioning hole 61 from the proximal end of the positioning hole 61, or even at least a portion of the operating part 34 can pass through the positioning hole 61. The positioning part 321 can be disposed on the first moving member 32.

[0097] In some embodiments, reference may be made to Figure 2 and Figure 3The first moving member 32 and the positioning member 6 are detachably connected, and when the pushing component 3 is in the second position, the first moving member 3 and the positioning member 6 are spaced apart longitudinally. This reduces interference between the positioning member 6 and the first moving member 3, and reduces wear between them, when the pushing component 3 moves between the first and second positions. Figure 3 In the embodiment shown, when the pushing component 3 is in the second position, a portion of the operating part 34 is located in the through hole on the positioning member 6, and the operating part 34 is spaced apart from the positioning member 6 in the through hole to reduce the interference of the positioning member 6 on the operating part 34 and the wear between them.

[0098] In some embodiments, reference may be made to Figure 2 and Figure 3 The aerosol generating device also includes a bracket 5 disposed between the positioning member 6 and the heating component 2. A first movable member 32 is movably disposed within the bracket 5. During the movement of the pushing component 3 relative to the heating component 2, the first movable member 32 moves within the bracket 5. The bracket 5 can limit the movement trajectory of the first movable member 32, and by limiting the movement trajectory of the first movable member 32, it limits the movement trajectory of the pushing component 3 relative to the heating component 2. For example, the bracket 5 can abut against the first movable member 32 laterally, thereby preventing the first movable member 32 from undergoing unexpected lateral deflection during displacement, which would prevent the positioning part 321 on the first movable member 32 from entering the positioning hole 61 during the repositioning of the pushing component 3 to the first position. The bracket 5's lateral abutment against the first movable member 32 also helps ensure that the positioning part 321 remains approximately aligned with the positioning hole 61 during the displacement of the first movable member 32.

[0099] In some embodiments, please refer to Figure 2 and Figure 3The support 5 includes a first stop wall 51 extending longitudinally and a second stop wall 52 extending longitudinally, with the first stop wall 51 and the second stop wall 52 spaced laterally. The pushing assembly 3 also includes a second moving member 33 linked to the first moving member 32. The first stop wall 51 is used to stop the first moving member 32 laterally, and the second stop wall 52 is used to stop the second moving member 33 laterally. Because the first moving member 32 and the second moving member 33 are linked, when the first moving member 32 is displaced, the position, shape, and / or angle of the second moving member 34 will change accordingly; or when the second moving member 33 is displaced, the position, shape, and / or angle of the first moving member 32 will change accordingly. Therefore, the first moving member 32 can be restrained laterally by the first stop wall 51, and the second moving member 33 can be restrained laterally by the second stop wall 52. The first moving member 32 and the second moving member 33 can restrain each other, thereby further ensuring that the positioning part 321 on the first moving member 32 can remain aligned with the positioning hole 61 on the positioning member 6 during the movement of the first moving member 32. Preferably, the positioning part 321 and the positioning hole 61 can substantially maintain a common central axis.

[0100] The first stop wall 51 can be slidably connected to the first moving member 32 to stop the first moving member 32 in the lateral direction. Of course, in order to reduce wear and reduce resistance, the first stop wall 51 can be spaced apart from the first moving member 32 and mainly abut against the first moving member 32 in the lateral direction when the first moving member 32 deflects laterally, so as to prevent the lateral deflection of the first moving member 32 from exceeding the expected value.

[0101] The second stop wall 52 can be slidably connected to the second moving member 33 to stop the second moving member 33 in the lateral direction. Of course, in order to reduce wear and reduce resistance, the second stop wall 33 can be spaced apart from the second moving member 33 and mainly abut against the second moving member 33 in the lateral direction when the second moving member 33 deflects laterally, so as to prevent the lateral deflection of the second moving member 33 from exceeding the expected value.

[0102] In such Figure 2 and Figure 3 In the illustrated embodiment, the reset assembly 4 is disposed between the first stop wall 51 and the second stop wall 52. The first stop wall 51 may be generally tubular and surrounds the periphery of the second stop wall 52. The first moving member 32 may be disposed inside the first stop wall 51. The second stop wall 52 may be generally tubular and surround at least partially the periphery of the second moving member 32.

[0103] In some embodiments, reference may be made to Figure 2 and Figure 3The second stop 52 is configured to be spaced apart from the first moving member 32 when the push component 3 is in the first position, and to abut against the first moving member 32 when the push component 3 is in the second position, so as to prevent the push component 3 from continuing to move longitudinally.

[0104] In some embodiments, the push assembly 3 includes a suction nozzle assembly 31 and a first moving member 32. The suction nozzle assembly 31 includes a suction nozzle 311 and an air guide tube 312 fluidly communicating between the suction nozzle 311 and the receiving cavity 21. The suction nozzle 311 can be held in the mouth of a user, who draws aerosol generated in the receiving cavity 21 by sucking on the suction nozzle 311. The suction nozzle assembly 31 is configured to be removable from the housing assembly 1 for cleaning or replacement. However, after the suction nozzle assembly 31 is removed from the housing assembly 1, the first moving member 32 may remain in the housing assembly 1. Based on this, in one example, reference can be made to... Figure 6 The first stop wall 51 has a longitudinally extending guide groove 511, and the first moving member 32 is provided with a latching part 322. During the movement of the pushing component 3 relative to the heating component 2, the latching part 322 moves within the guide groove 511. When the pushing component 3 is in the first position, the latching part 322 abuts against one end edge of the guide groove 511, preventing the first moving member 32 from detaching from the bracket 5. To reduce wear, it is preferable that the latching part 322 is spaced apart from the bracket 5 when moving within the guide groove 511. It should be noted that the suction nozzle assembly 31 is removable from the housing assembly 1, making it optional rather than mandatory.

[0105] You can refer to Figure 2 and Figure 6 The aerosol generating apparatus provided in some embodiments of this application further includes a suction nozzle 311 and a first end cap assembly 7 connected to one end of the heating assembly. The first end cap assembly 7 includes a support base 71 and a first sealing member 72 fixed on the support base 71. The first sealing member 72 has a through hole 721. The pushing assembly 3 includes an air guide tube 312, which is movable between a first position and a second position. At least a portion of the air guide tube 312 is movably disposed in the through hole 721, so that during the movement of the air guide tube 312 between the first position and the second position, the air guide tube 312 can move relative to the through hole 721 or move axially along the through hole 721. The air guide tube 312 is in fluid communication with the suction nozzle 311 and the receiving cavity 21. The air guide tube 312 can be directly connected to the suction nozzle 311. The air guide tube 312 can be connected to and in fluid communication with the suction nozzle 311 through other components with air guiding functions.

[0106] The air guide tube 312 includes a first part 3121 and a second part 3122, the outer diameter of the second part 3122 being larger than the outer diameter of the first part 3121; the air guide tube 312 is configured such that when the push assembly 3 or the air guide tube 312 is in the first position, the second part 3122 is located in the through hole 721 and is sealed to the first seal 72, and when the push assembly 3 or the air guide tube 312 is in the second position, the first part 3121 is located in the through hole 721. Therefore, during the movement of the push assembly 3 or the air duct 312 between the first and second positions, the first seal 72 can only be tightly engaged with the air duct 312 during a portion of the movement. Compared to the first seal 72 being tightly engaged with the air duct 312 throughout the entire movement, this helps to reduce wear on the first seal 72. This ensures that during long-term use, the first seal 72 can maintain a sealed connection with the air duct 312 when the push assembly 3 is in the first position, preventing the aerosol in the receiving cavity 21 from leaking out between the first end cap assembly 7 and the air duct 312.

[0107] It should be noted that this embodiment can be combined with any of the above embodiments to form a new technical solution, or it can be independent of any embodiment having positioning member 6 and positioning part 321.

[0108] In such Figure 2 and Figure 3 In the provided embodiment, the air guide tube 312 consists of two sections. For ease of description, the section connected to and in fluid communication with the nozzle 311 is defined as the first tube, and the other section is defined as the second tube. The distal end of the first tube and the proximal end of the second tube can be nested together. The end of the second tube can be riveted into the first tube, or the end of the first tube can be riveted into the second tube. The distal end of the first tube and the proximal end of the second tube can be welded together. The first tube can be made of metal. The second tube can be formed by plastic injection molding. The first tube and the second tube can be made of the same material. The first tube and the second tube can be made of different materials. The first part 3121 and the second part 3122 can both be components of the second tube. The first part 3121 can be a component of the first tube, and the second part 3122 can be a component of the second tube.

[0109] The air guide tube 312 can be moved from the first position to the second position by the operating part 34. The operating part 34 can be the suction nozzle 311, or it can be other components other than the suction nozzle 311, which are not specifically limited here.

[0110] In such Figures 2-4In the illustrated embodiment, the air guide tube 312 may further include a third portion 3123, with the second portion 3122 located between the first portion 3121 and the third portion 3123, and the outer diameter of the third portion 3123 being smaller than the outer diameter of the second portion 3122. When the pushing component 3 or the air guide tube 312 is in the first position, the third portion 3123 may be located outside the receiving cavity 21; specifically, the third portion 3123 may be located within the first end cap assembly 7. When the pushing component 3 is in the second position, at least a portion of the third portion 3123 is located within or through the receiving cavity 21. Further, during the movement of the pushing component 3 or the air guide tube 312 from the first position to the second position, the pushing component 3 compresses the aerosol-generating product through the end of the third portion 3123, thereby pushing the aerosol-generating product out of the receiving cavity 21, causing the aerosol-generating product to detach from the assembly port 11 from the housing assembly 1.

[0111] Please refer to Figure 3 When the push assembly 3 or the air duct 312 is in the second position, at least a portion of the second part 3122 can be located in the first end cap assembly 7 and spaced apart from the first end cap assembly 7. Thus, when the second part 3122 is mainly in the through hole 721, there is a large interference fit force between it and the first end cap assembly 7, which helps to reduce the wear on the second part 3122. This allows the second part 3122 to still form a sealing connection with the first seal 72 when it is located in the through hole 721 after long-term use.

[0112] You can refer to Figure 3 and Figure 4 The push assembly 3 may also include a filter 313, which is connected to the third part 3123. The filter 313 can be used to prevent solid aerosol matrix fragments in the aerosol generating article from being drawn into the nozzle 311. The filter 313 may include a metal mesh. The filter 313 can be detachably connected to the third part 3123, thereby allowing the filter 313 to be removed for replacement or cleaning. The second part 3122 and the third part 3123 can be integrally formed, and then the second part 3122 is connected to the first part 3121. Of course, the third part 3123 is optional and not mandatory; when the third part 3123 is not present, the filter 313 can be connected to the second part 3122.

[0113] You can refer to Figures 6-8 In some embodiments of the present application, the aerosol generating apparatus includes a heating component 2 including a tubular body 22 that is at least partially disposed around the receiving cavity 21. The aerosol generating apparatus also includes a first end cap assembly 7, the first end cap assembly 7 and the assembly port 11 being disposed on opposite sides of the receiving cavity 21. The aerosol generating apparatus also includes a suction nozzle assembly 31 that is in fluid communication with the receiving cavity 21.

[0114] When the aerosol-generating article is contained in the receiving cavity 21, there is a gap between the edge region of the aerosol-generating article and the first end cap assembly 7, which is in fluid communication with the nozzle assembly 31. Normally, a portion of the airflow exits the aerosol-generating article from its edge region, and a portion exits from its center region. However, for some aerosol-generating articles, more airflow exits through the edge region than through the center region. However, after the aerosol-generating article containing a solid aerosol-forming matrix is ​​contained in the receiving cavity 21, the edge region of the solid aerosol-forming matrix abuts against or adheres to the first end cap assembly 7, thereby blocking the pores in the edge region of the solid aerosol-forming matrix. This makes it difficult for the airflow in the solid aerosol-forming matrix to flow into the nozzle assembly 31 through the edge region. Therefore, by creating a gap between the edge region of the aerosol-generating article and the first end cap assembly 7 that is in fluid communication with the mouthpiece assembly 31, the pores in the edge region of the aerosol-generating article can be prevented from being blocked, thereby helping to ensure sufficient aerosol flow into the mouthpiece assembly 31 and improving the sucking experience.

[0115] It should be noted that this embodiment can be combined with any of the above embodiments to form a new technical solution, or it can be independent of any of the above embodiments.

[0116] In such Figures 6-8 In the illustrated embodiment, the first end cap assembly 7 includes an insert 731 disposed inside the tubular body 22. The insert 731 has a notch 7311 at its end facing the assembly port 11, and the notch 7311 is in fluid communication with the nozzle assembly 31. When the aerosol-generating article is contained in the receiving cavity 21, the insert 731 abuts against the aerosol-generating article. At least a portion of the aforementioned gap is located within the notch 7311, allowing airflow from the edge region of the aerosol-generating article to flow into the nozzle assembly 31 through the notch 7311.

[0117] Furthermore, the insert 731 can be disposed close to the inner wall of the tubular body 22, so that a portion of the edge area of ​​the aerosol generating article can be abutted by the insert 731, while a portion of the edge area has a gap with the insert 731, so that the airflow in the edge area of ​​the aerosol generating article can flow out of the aerosol generating article and then flow into the nozzle assembly 31.

[0118] More specifically, the first end cap assembly 7 includes a support 71 and a second seal 73 fixed on the support 71. The second seal 73 may include a sealing portion 732 disposed between the support 71 and the tubular body 22 to provide a seal between the support 71 and the tubular body 22, preventing airflow in the receiving cavity 21 from leaking between the first end cap assembly 7 and the tubular body 22.

[0119] The insert 731 can be a component of the second seal 73. The insert 731 can be integrally formed with the seal 732. The outer surface of the insert 731 can be in close contact with the inner wall of the tubular body 22.

[0120] In such Figure 2 and Figure 3 In the illustrated embodiment, the aerosol generating apparatus further includes a second end cap assembly 9. The second end cap assembly 9 and the first end cap assembly 7 are disposed on opposite sides of the receiving cavity 21. When the aerosol-generated article is contained in the receiving cavity 21, the second end cap assembly 9 supports the aerosol-generated article, thereby enabling the aerosol-generated article to be held in the receiving cavity 21.

[0121] The blocking plug 8 can be connected to the second end cap assembly 9, so that when the blocking plug 8 is removed from the assembly port 11, it can drive the second end cap assembly 9 to move away, causing the aerosol-generated product in the receiving cavity 21 to lose support, thereby allowing the aerosol-generated product to be removed. Therefore, the pushing assembly 3 can be driven to move to the second position, so that the pushing assembly 3 pushes the aerosol-generated product outside the housing assembly 1.

[0122] In an embodiment where the push assembly 3 includes a suction resistance assembly 31, the suction nozzle 311 in the suction nozzle assembly 31 can constitute the operation part 34 of the push assembly 3. The user can drive at least a portion of the air guide tube 312 in the suction nozzle assembly 31 into or through the receiving cavity 21 by operating the suction nozzle 311, thereby pushing the aerosol-generated article out of the receiving cavity 21.

[0123] 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. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
