[0002] The present disclosure is based on a Chinese patent application with application number 202311862572.6 and a filing date of December 29, 2023, and claims priority to said Chinese patent application, the entire contents of said Chinese patent application are incorporated by reference into the present disclosure.
[0003] The present disclosure relates to the field of atomization technology, and in particular to an aerosol generating device and an aerosol generating system. Background Technology
[0004] This section is intended to provide background or context for the embodiments specified in this disclosure. The description in this specification is not to be considered prior art merely because it is included in this section.
[0005] An aerosol generator is a type of electronic transfer system that controls the operating state and aerosol output amount through control circuits and heating elements to enable user access.
[0006] Conventional heated aerosol media (e.g., cigarette media) and heating element assemblies typically have a cylindrical shape. Since the heat transfer path is relatively long in the center of the cylindrical aerosol media and the thermal resistance of the aerosol media is extremely high, it is easy for insufficient heating to occur in the area near the center of the aerosol media, resulting in wasted aerosol media. If the heating time is extended or the heating power is increased, the aerosol media on the outer edge burns easily due to repeated heating or excessive temperature, degrading the user experience; at the same time, because the aerosol media and heating element assembly have a cylindrical shape, the structural volume of the aerosol generating device increases. If this is attempted to be resolved by reducing the diameter of the aerosol media, the length of the aerosol media must be increased to satisfy sufficient inhalation frequency and sufficient release of active ingredients, which consequently increases the length of the aerosol generating device and worsens the user experience.

[0038] In the description of the embodiments of the present disclosure, it is necessary to note that the orientation or positional relationship indicated by terms such as "up," "down," "top," "bottom," "first direction," "second direction," etc., is based on the orientation or positional relationship illustrated in FIGS. 2 and FIGS. 5. These orientation terms are intended merely to conveniently describe the embodiments of the present disclosure and to simplify the description, and do not indicate or imply that the mentioned devices or components must necessarily have a specific orientation or be configured and operated in a specific orientation; therefore, they should not be understood as limitations on the embodiments of the present disclosure. The present disclosure is described in more detail below in combination with the drawings and specific embodiments.
[0039] One aspect of an embodiment of the present disclosure provides an aerosol generating system, and with reference to FIGS. 1 through 8, it includes an aerosol generating product (200) and an aerosol generating device (100) of any embodiment described above. The aerosol generating product (200) is placed in a receiving chamber (100a) of the aerosol generating device (100), and in a cross-section perpendicular to the height direction of the aerosol generating device (100), the cross-sectional shape of the aerosol generating product (200) corresponds to the cross-sectional shape of the receiving chamber (100a).
[0040] The aerosol generating product (200) is placed in a receiving chamber (100a), and a heating unit (20) is used to heat the aerosol generating product (200) to generate an aerosol.
[0041] It is necessary to explain that, in the embodiment of the present disclosure, with reference to FIG. 2 and FIG. 3, the aerosol generating product (200) is in a solid form.
[0042] The structure of the aerosol generating product (200) is not limited. For example, in some embodiments, the aerosol generating product (200) may include a functional section and an aerosol generating substrate, and the functional section is disposed at one end along the longitudinal direction of the aerosol generating substrate. It is necessary to explain that the aerosol generating product (200) generates aerosols depending on the aerosol generating substrate, and the functional section does not generate aerosols.
[0043] The functional section may include a temperature reduction section to cool the aerosol to lower its temperature and to alleviate the "burning of the mouth" phenomenon when a user inhales the aerosol. The functional section may additionally include a support section, which has a certain structural strength and acts as a positional limiting factor along its axial direction relative to the aerosol generating substrate. The functional section may also include a filtration section for filtering the aerosol.
[0044] In some other embodiments, the aerosol generating product (200) does not include a functional section.
[0045] The aerosol generating product (200) may additionally include an outer wrapping layer, the outer wrapping layer covering the outer side of the functional section and the aerosol generating substrate, and of course, the aerosol generating product (200) may not have an outer wrapping layer. Specifically, in the embodiments of the present disclosure, an aerosol generating product (200) without an outer wrapping layer is described as an example.
[0046] The material of the aerosol generating substrate is not limited. For example, the aerosol generating product (200) may include, but is not limited to, pharmaceuticals, nicotine-containing materials, or nicotine-free materials, and in one embodiment, the aerosol generating substrate may include tobacco materials. In one example, a macroscopic internal airflow passage (200a) is provided in the aerosol generating substrate, and the aerosol generating substrate may be manufactured by methods such as extrusion or die casting, and the internal airflow passage (200a) may be formed directly by methods such as extrusion or die casting. Of course, the aerosol generating substrate may additionally have microscopic air holes inside, and is not limited thereto.
[0047] The above aerosol generating product (200) includes, but is not limited to, materials used for medical, curing, health, beauty, etc.
[0048] Another aspect of an embodiment of the present disclosure provides an aerosol generating device (100), which, with reference to FIGS. 1 through 7, comprises a housing assembly (10) and a heating unit (20). A mounting space (11a) is provided in the housing assembly (10). The heating unit (20) is disposed at least partially within the mounting space (11a) and forms at least a portion of a receiving chamber (100a) for receiving an aerosol generating product (200). In a cross-section perpendicular to the height direction of the aerosol generating device (100), the dimension along the first direction of the cross-section of the receiving chamber (100a) is greater than the dimension along the second direction, wherein the first direction intersects the second direction.
[0049] The fact that the heating unit (20) is placed at least partially within the mounting space (11a) means that the heating unit (20) may be placed partially within the mounting space (11a) or entirely within the mounting space (11a).
[0050] The fact that the heating unit (20) forms to limit at least a part of the receiving chamber (100a) for receiving an aerosol generating product (200) means that the heating unit (20) may limit a part of the receiving chamber (100a) or may limit the entire receiving chamber (100a).
[0051] A heating unit (20) is formed by defining at least a portion of a receiving chamber (100a) for receiving an aerosol generating product (200), and the heating unit (20) heats the aerosol generating product (200) to generate an aerosol, that is, the aerosol generating product (200) of the embodiment of the present disclosure is subjected to circumferential heating, that is, the heating unit (20) performs circumferential heating on the aerosol generating product (200).
[0052] In a cross-section perpendicular to the height direction of the aerosol generating device (100), the cross-sectional shape of the aerosol generating product (200) corresponds to the cross-sectional shape of the receiving chamber (100a), which is advantageous for the assembly of the aerosol generating product (200), the miniaturization of the aerosol generating device (100), and the improvement of heating efficiency.
[0053] Referring to FIGS. 5, 7, and 8, in a cross-section perpendicular to the height direction of the aerosol generating device (100), the dimension along the first direction of the cross-section of the receiving chamber (100a) is larger than the dimension along the second direction, that is, the receiving chamber (100a) has a flat shape cavity, and the corresponding aerosol generating product (200) also has a flat shape.
[0054] The first direction is, for example, the length direction of the aerosol generating device (100), and the second direction is, for example, the width direction of the aerosol generating device (100).
[0055] The shape of the receiving chamber (100a), which has a flat cross-sectional shape, varies, and for example, the cross-sectional shape of the receiving chamber (100a) is rectangular, elliptical, ladder-shaped, or track-shaped.
[0056] Here, the track shape refers to a shape similar to an athletics track, and is formed by alternately connecting two semicircles or arcs of the same radius and two parallel straight edges.
[0057] If the cross-sectional shape of the receiving chamber (100a) is rectangular, the receiving chamber (100a) can be smoothly connected through an arc at the vertex portion, or it can be smoothly connected without an arc.
[0058] If the cross-sectional shape of the receiving chamber (100a) is ladder-shaped, the receiving chamber (100a) can be smoothly connected through an arc at the apex portion, or it can be smoothly connected without an arc.
[0059] The shape of the aerosol generating product (200) having a flat cross-sectional shape is varied, and for example, the cross-sectional shape of the aerosol generating product (200) is rectangular, elliptical, trapezoidal, or track-shaped.
[0060] If the cross-sectional shape of the aerosol generating product (200) is rectangular, the aerosol generating product (200) can be smoothly connected through an arc at the vertex portion, or can be smoothly connected without an arc.
[0061] In one specific embodiment, by setting the cross-sectional shapes of both the aerosol generating product (200) and the receiving chamber (100a) to be rectangular or track-shaped, the structure of the heating unit (20) is optimized to achieve lightweight and slimming of the entire aerosol generating device (100), and the thickness (dimension along the second direction of the aerosol generating device (100)) reaches 8mm to 12mm, for example, 8mm, 9mm, 10mm, 11mm, or 12mm.
[0062] For example, referring to FIGS. 2 and FIGS. 8, the aerosol generating device (100) further includes a power supply unit, and the power supply unit is electrically connected to a heating unit (20).
[0063] Here, the power supply unit is mainly used to supply power to the heating unit (20) and to control operations such as turning on or off the entire aerosol generating device (100).
[0064] It is necessary to explain that the specific type of aerosol generating device (100) provided in the embodiment of the present disclosure is not limited, and, for example, the aerosol generating device (100) may be a medical atomizing device, an air humidifier, or an atomizing device such as an electronic cigarette.
[0065] The housing assembly (10) can be understood as the main body part of the aerosol generating device (100), and the housing assembly (10) forms the approximate frame of the aerosol generating device (100).
[0066] At least a portion of the housing assembly (10) can function as an exterior part of the aerosol generating device (100), and the mounting space (11a) can facilitate the placement of the heating unit (20).
[0067] An aerosol generating device (100) provided in an embodiment of the present disclosure comprises a housing assembly (10) and a heating unit (20), wherein the heating unit (20) is disposed at least partially within a mounting space (11a) of the housing assembly (10) and together with the housing assembly (10) defines a receiving chamber (100a) for receiving an aerosol generating product (200), and the heating unit (20) heats and atomizes the aerosol generating product (200) to generate an aerosol. In a cross-section perpendicular to the height direction of the aerosol generating device (100), by setting the dimension along the first direction of the cross-section of the receiving chamber (100a) larger than the dimension along the second direction, that is, by making the receiving chamber (100a) have a flat shape, the aerosol generating device (100) of the embodiment of the present disclosure has reduced the dimension along the second direction of the receiving chamber (100a) to some extent compared to a receiving chamber (100a) with a circular cross-section under the premise that the cross-sectional area is constant. Doing so is advantageous for realizing the miniaturization of the aerosol generating device (100) and improves the user experience. In addition, the receiving chamber (100a) having a flat shape shortens the minimum distance between the heating unit (20) and the center of the aerosol generating product (200) during the heating process, thereby shortening the heat transfer path and being advantageous for performing fast, efficient, and uniform heating, which improves heating performance and, accordingly, improves the atomization effect.
[0068] In some embodiments, in a cross-section perpendicular to the height direction of the aerosol generating device (100), the ratio range of the dimension along the first direction and the dimension along the second direction of the cross-section of the receiving chamber (100a) is 1.2 to 11. For example, 1.2, 1.3, 1.5, 1.8, 2.0, 2.3, 2.4, 2.5, 2.7, 2.8, 2.9, 3.0, 3.5, 4.0, 4.8, 5.0, 5.3, 6.0, 6.4, 7.0, 7.5, 8.0, 8.7, 9.0, 9.8, 10.0, 10.6, or 11.0, etc.
[0069] By setting the ratio range of the dimensions along the first direction and the dimensions along the second direction of the cross-section of the receiving chamber (100a) to 1.2 to 11, it is advantageous to achieve miniaturization of the aerosol generating device (100), shorten the heat transfer path, and perform fast, efficient, and uniform heating, thereby improving heating performance and, accordingly, improving the atomization effect.
[0070] In some embodiments, in a cross-section perpendicular to the height direction of the aerosol generating device (100), the ratio range of the dimension along the first direction and the dimension along the second direction of the cross-section of the receiving chamber (100a) is 1.8 to 2.3. For example, 1.8, 1.9, 2.0, 2.1, 2.2, or 2.3, etc.
[0071] By setting the ratio range of the dimensions along the first direction and the dimensions along the second direction of the cross-section of the receiving chamber (100a) to 1.8 to 2.3, it is not only more advantageous to realize the miniaturization of the aerosol generating device (100) but also further improves the heating performance, thereby improving the atomization effect.
[0072] In some embodiments, referring to FIGS. 3 through 7, the heating unit (20) includes a connecting member (21) and a heating member (22) fixed to the connecting member (21). The connecting member (21) is connected to a housing assembly (10). The heating member (22) is located within a mounting space (11a) and is used to heat and atomize an aerosol generating product (200) to generate an aerosol.
[0073] The type of the heating element (22) is not limited. For example, referring to FIGS. 3 through 8, the heating element (22) is tubular, and in a cross-section perpendicular to the height direction of the aerosol generating device (100), the cross-sectional shape of the heating element (22) is rectangular, elliptical, trapezoidal, or track-shaped. The internal space of the heating tube constitutes a partial receiving chamber (100a).
[0074] The material of the heating tube is not limited. For example, it may be stainless steel or a quartz tube. The heating tube is used to heat the aerosol generating product (200) to generate an aerosol. In other words, the aerosol generating product (200) of the embodiment of the present disclosure is subjected to circumferential heating.
[0075] The heating technology of the heating tube is not limited. For example, it can be electromagnetic induction heating or resistance film heating.
[0076] The heating unit (20) is secured by directly connecting the connecting member (21) to the housing assembly (10). In the related technology, the heating unit (20) is secured by setting the connecting member (21) that is gripped at both ends of the heating member (22) and installing a fixing bracket around the outer perimeter of the heating member (22) to secure the connecting member (21) located at both ends of the heating member (22). In contrast, the aerosol generating device (100) of the embodiment of the present disclosure may choose not to additionally set a fixing bracket for securing the connecting member (21), and the heating unit (20) is secured by directly connecting the connecting member (21) to the housing assembly (10). Doing so is advantageous for miniaturizing the aerosol generating device (100), reducing parts, lowering costs, and increasing assembly efficiency to improve the user experience. In addition, since a separate fixing bracket for fixing the heating unit (20) is not set, it is advantageous to reduce the amount of heat generated from the heating unit (20) being transferred to the fixing bracket, and the amount of heat can be preserved as much as possible within the heating unit (20), thereby reducing energy consumption during heating and improving heating performance.
[0077] In some embodiments, referring to FIGS. 2 through 4, the housing assembly (10) includes a housing body (11) and an air exhaust unit (12) connected to the housing body (11). The housing body (11) is provided with a mounting space (11a) and an opening (11b) communicating with the mounting space (11a). The air exhaust unit (12) is positioned in the opening (11b) and defines the heating unit (20) and the receiving chamber (100a). An air exhaust passage (12c) communicating with the receiving chamber (100a) is additionally formed in the air exhaust unit (12).
[0078] The specific method of connecting the air discharge unit (12) and the housing body (11) is not limited here, and, for example, the air discharge unit (12) and the housing body (11) may be connected by a magnetic adsorption connection, a hook connection, a fastening connection, or an insertion connection.
[0079] Here, fastening connections include, but are not limited to, screw connections, bolt connections, or rivet connections.
[0080] For example, the air exhaust unit (12) and the housing body (11) are joined by a locking mechanism, which is advantageous for implementing disassembly and assembly between the air exhaust unit (12) and the housing body (11).
[0081] In one specific embodiment, referring to FIGS. 2 to 4, a catch protruding flange is formed on the circumferential side wall of the air discharge unit (12), and a catch concave groove is formed in the opening (11b) of the housing body (11), and the catch protruding flange and the catch concave groove are engaged so that the air discharge unit (12) and the housing body (11) are engaged. In another specific embodiment, the part where the air discharge unit (12) and the housing body (11) come into contact is made of a soft material (e.g., rubber, silicone, etc.), and when the air discharge unit (12) and the housing body (11) come into contact, elastic deformation occurs in the air discharge unit (12) to join with the housing body (11), for example, by being inserted into the housing body (11) through the opening (11b), and when disassembly and assembly are required, the air discharge unit (12) can simply be pulled out directly. Of course, the entire air exhaust unit (12) may be made of a soft material, and is not limited thereto.
[0082] In this embodiment, by configuring the housing assembly (10) to include a housing body (11) and an air discharge unit (12), an air discharge passage (12c) is installed in the air discharge unit (12) so that the aerosol generated by the heating element (22) heating and atomizing the aerosol generating product (200) can enter the air discharge passage (12c) from the receiving chamber (100a) and be inhaled by the user. In other words, filtration, cooling, etc., can be performed on the aerosol through the air discharge unit (12), so that it is not necessary to set a functional section and an external wrapping layer in the aerosol generating product (200). That is to say, the aerosol generating product (200) of this embodiment may include only an aerosol generating substrate, thereby saving parts such as temperature reduction and filtration inside the aerosol generating product (200), simplifying the manufacturing process and packaging volume of the aerosol generating product (200), lowering costs, and ensuring that the functional section, etc., is not discarded without permission after inhalation, which is advantageous for environmental protection.
[0083] Additionally, depending on the product style characteristics, substances such as filtration and flavoring can be placed inside the air discharge unit (12), which is advantageous for improving the texture of the aerosol.
[0084] In some embodiments, in a cross-section perpendicular to the height direction of the aerosol generating device (100), the cross-sectional shape of the air discharge unit (12) corresponds to the cross-sectional shape of the opening (11b). This is advantageous for the connection between the air discharge unit (12) and the housing body (11).
[0085] The shape in which the air exhaust unit (12) and the heating unit (20) define the receiving chamber (100a) varies.
[0086] For example, in some embodiments, with reference to FIGS. 2 to 4, a first receiving groove (20a) is installed in the heating unit (20) and a second receiving groove (12a) is installed in the air discharge unit (12), and the first receiving groove (20a) and the second receiving groove (12a) together form a receiving chamber (100a). One end of the aerosol generating product (200) is inserted into the first receiving groove (20a), and the other end of the aerosol generating product (200) is inserted into the second receiving groove (12a).
[0087] In other words, one end of the aerosol generating product (200) is inserted into the heating unit (20) and the other end is inserted into the air exhaust unit (12), that is, the heating unit (20) and the air exhaust unit (12) hold the aerosol generating product (200) between them to achieve fixation of the aerosol generating product (200).
[0088] The aerosol generated by heating the aerosol generating product (200) with the heating unit (20) can be introduced into the air discharge passage (12c) within the air discharge unit (12) through the airflow passage (200a) placed inside the aerosol generating product (200), thereby making it convenient to mount and fix the aerosol generating product (200), and also allowing filtration and cooling to be performed through the air discharge unit (12), which is advantageous for the aerosol to flow out quickly, and at the same time, it is possible to make it unnecessary to set functional sections and external wrapping layers on the aerosol generating product (200).
[0089] In some other embodiments, a first receiving groove (20a) may be installed in the heating unit (20) and a second receiving groove (12a) may not be installed in the air exhaust unit (12) but instead may be installed by covering the upper portion of the first receiving groove (20a) to form a receiving chamber (100a) together with the first receiving groove (20a).
[0090] In some embodiments, referring to FIGS. 4 and 6, a protruding rib (12b) is installed on the groove wall of the second receiving groove (12a) and is used to force-fit the air discharge unit (12) and the aerosol generating product (200). In other words, by installing the protruding rib (12b) on the groove wall of the second receiving groove (12a), the air discharge unit (12) and the aerosol generating product (200) are force-fitted together. This is advantageous for positioning the aerosol generating product (200) at the center of the receiving chamber (100a) and for further securing the aerosol generating product (200). Additionally, the entry of external air into the air discharge passage (12c) through the gap between the air discharge unit (12) and the aerosol generating product (200) can be minimized.
[0091] The number of protruding ribs (12b) may be one or multiple.
[0092] It is necessary to explain that the protruding rib (12b) may extend along the axial direction of the second receiving groove (12a) (i.e., the height direction of the aerosol generating device (100)) and may also extend along the circumferential direction of the second receiving groove (12a).
[0093] The air exhaust unit (12) is, for example, a mouthpiece, and the material of the air exhaust unit (12) is not limited thereto, and, for example, the air exhaust unit (12) is made of, for example, a soft rubber material, and this is advantageous for inserting an aerosol generating product (200) into the air exhaust unit (12).
[0094] In some embodiments, referring to FIG. 6, the flow cross-sectional area of the air discharge passage (12c) is smaller than the flow cross-sectional area of the second receiving groove (12a). Additionally, the flow cross-sectional area of the air discharge passage (12c) gradually increases along the direction of airflow.
[0095] It is necessary to explain that the flow cross-section refers to a cross-section perpendicular to all streamlines of the source or stream, that is, a plane perpendicular to the velocity bundles, such as air or liquid flow. When the streamline bundles are not parallel to each other, the flow cross-section becomes a curved surface; when the streamline bundles are parallel straight lines, the flow cross-section becomes a flat surface.
[0096] It can be understood that the flow cross-sectional area of the air discharge passage (12c) gradually increases along the direction of airflow. In this way, the velocity of the airflow in the air discharge passage (12c) gradually decreases and the air pressure gradually increases, so that the air pressure shows a continuous change trend and the turbulence of the airflow can be reduced.
[0097] Of course, the air exhaust passage (12c) additionally includes equal sections. It is necessary to explain that the area of the flow cross-section of the air exhaust passage (12c) located in the equal sections along the direction of airflow is the same.
[0098] The flow cross-sectional area of the air discharge passage (12c) is smaller than the flow cross-sectional area of the second receiving groove (12a). In this way, when air flows from the second receiving groove (12a) into the air discharge passage (12c), the flow velocity gradually increases and the air pressure gradually decreases, so that the air pressure shows a continuous change trend and the turbulence of the airflow can be reduced.
[0099] The flow cross-sectional area of the second receiving groove (12a) is relatively large, which is advantageous for the aerosol generated by the aerosol generating product (200) to pass through the airflow passage (200a) placed inside the aerosol generating product (200) and collect at one end of the second receiving groove (12a) adjacent to the air discharge passage (12c). By setting the flow cross-sectional area of the air discharge passage (12c) to be smaller than the flow cross-sectional area of the second receiving groove (12a), that is, by reducing the flow cross-sectional area of the air discharge passage (12c), it is advantageous for increasing the flow velocity of the aerosol, thereby improving the user experience.
[0100] In some embodiments, referring to FIGS. 3 through 6, the second receiving groove (12a) includes a connecting section (12e) and a contracting section (12n), the connecting section (12e) is used to receive an aerosol generating product (200), the contracting section (12n) is in communication with an air discharge passage (12c), and the flow cross-sectional area of the contracting section (12n) gradually decreases along the direction of airflow.
[0101] The aerosol generated by the aerosol generating product (200) passes through the airflow passage (200a) placed inside the aerosol generating product (200) and collects in the contraction section (12n).
[0102] Setting the flow cross-sectional area of the air discharge passage (12c) to be smaller than the flow cross-sectional area of the second receiving groove (12a) produces the effect of applying a design similar to a Venturi tube, and when the restricted flow passes through the reduced flow cross-sectional area, the fluid velocity increases, and the velocity is inversely proportional to the flow cross-sectional area. As the airflow carrying the aerosol flows through the contracted section (12n) and the air discharge passage (12c) of this structure, the velocity increases, and as a result, the heat exchange efficiency between the aerosol and the inner wall of the air discharge unit (12) is increased and the temperature of the aerosol is lowered.
[0103] In some embodiments, with reference to FIGS. 4 and FIGS. 6, an air discharge unit (12) is provided with an air replenishment passage (12d), one end of the air replenishment passage (12d) penetrates the outer wall of the air discharge unit (12), and the other end communicates with the one end adjacent to the air discharge passage (12c) where the second receiving groove (12a) is in communication with the air discharge passage (12c) and / or the second receiving groove (12a).
[0104] The aerosol generated by the aerosol generating product (200) is collected within the airflow passage (200a) placed inside the aerosol generating product (200), and during the intake process, negative pressure is generated within the air discharge passage (12c) and the second receiving groove (12a), causing the aerosol in the airflow passage (200a) to flow sequentially into the second receiving groove (12a) and the air discharge passage (12c) under the action of negative pressure. At the same time, cold outside air flows through the air replenishment passage (12d) and / or the second receiving groove (12a) under the action of negative pressure to neutralize the aerosol and cool the aerosol, which is advantageous for improving the texture of the aerosol.
[0105] In some embodiments, an air supply passage (12d) is provided in the air discharge unit (12), and one end of the air supply passage (12d) penetrates the outer wall of the air discharge unit (12), and the other end penetrates the side wall of the air discharge passage (12c) and / or the second receiving groove (12a). Specifically, referring to FIGS. 4 and 6, one end of the air supply passage (12d) penetrates the outer wall of the air discharge unit (12), and the other end is in communication with the contraction section (12n). In other words, one end of the air supply passage (12d) penetrates the outer wall of the air discharge unit (12), and the other end penetrates the inner wall of the contraction section (12n).
[0106] As the flow cross-sectional area of the contraction section (12n) is gradually reduced, the fluid velocity increases when the restricted flow passes through the reduced flow cross-sectional area. Consequently, cold outside air is introduced into the contraction section (12n), which is advantageous for sufficient mixing of the cold air and the aerosol, thereby further enhancing the cooling effect and improving the texture of the aerosol.
[0107] In some embodiments, with reference to FIGS. 3 and FIGS. 4, an air inlet passage is installed in the aerosol generating device (100), and a first sub-air passage (100b) constituting at least a part of the air inlet passage is installed in the housing assembly (10), and a receiving chamber (100a) is in communication with the outside through the first sub-air passage (100b).
[0108] The first sub-air passage (100b) constituting at least a part of the air inlet passage is installed in the housing assembly (10), that is, the first sub-air passage (100b) is installed in the housing assembly (10) and the first sub-air passage (100b) constituting at least a part of the air inlet passage.
[0109] The receiving chamber (100a) is connected to the outside through the first sub-air passage (100b), and when the user inhales, the external airflow enters the receiving chamber (100a) through the first sub-air passage (100b) and carries the aerosol generated within the receiving chamber (100a) into the user's mouth so that the user can inhale.
[0110] It is necessary to explain that the form in which the first sub-air passage (100b) is installed in the housing assembly (10) varies. For example, in some embodiments, the first sub-air passage (100b) is formed in the housing body (11). In other embodiments, the first sub-air passage (100b) is formed in the air discharge unit (12). In yet another embodiment, referring to FIG. 3, the first sub-air passage (100b) is defined between the housing body (11) and the air discharge unit (12), for example, the first air inlet groove is installed in the air discharge unit (12), and the first sub-air passage (100b) is defined between the groove wall of the first air inlet groove and the housing body (11).
[0111] In some embodiments, with reference to FIGS. 3 and 4, a heating unit (20) is provided with a first receiving groove (20a), and the first receiving groove (20a) constitutes at least a part of a receiving chamber (100a). The air inlet passage further includes a second sub-air passage (100c), and the second sub-air passage (100c) is formed in a limited manner between the groove wall of the first receiving groove (20a) and the aerosol generating product (200) received within the first receiving groove (20a), and the second sub-air passage (100c) communicates with the first sub-air passage (100b).
[0112] The groove wall of the first receiving groove (20a) can be understood as a wall in any direction of the first receiving groove (20a).
[0113] The second sub-air passage (100c) can be understood as a gap formed between the aerosol generating product (200) placed within the first receiving groove (20a) and the groove wall of the first receiving groove (20a).
[0114] When a user inhales an aerosol, it can be understood that the external airflow passes through the first sub-air passage (100b), enters the second sub-air passage (100c), and then enters the aerosol generating product (200) to take the aerosol.
[0115] In some embodiments, referring to FIGS. 3 and 4, the second sub-air passage (100c) includes a first air inlet section (100d) and a second air inlet section (100e) that are in communication with each other. The first air inlet section (100d) is located on the periphery side of the aerosol generating product (200) contained within the first receiving groove (20a). The second air inlet section (100e) is located at one end of the aerosol generating product (200) contained within the first receiving groove (20a) away from the air discharge unit (12).
[0116] In this embodiment, when a user inhales an aerosol, the external airflow can enter the second air inlet section (100e) through the first sub-air passage (100b) and the first air inlet section (100d), and the airflow that has entered the second air inlet section (100e) enters the airflow passage (200a) inside the aerosol generating product (200) from the cross-section of the aerosol generating product (200) moving away from the air discharge unit (12), and then flows toward the side adjacent to the air discharge unit (12). By doing so, the airflow path inside the aerosol generating product (200) becomes larger, allowing the maximum amount of aerosol inside the aerosol generating product (200) to be extracted.
[0117] In some embodiments, referring to FIG. 7, the connecting member (21) includes at least two connecting brackets. The two connecting brackets are positioned at both ends along the height direction of the heating member (22) and are each connected to the housing body (11). In other words, by setting up two connecting brackets, the two connecting brackets are each positioned at both ends along the height direction of the heating member (22) to secure the heating member (22), and the two connecting brackets are each connected to the housing body (11) to secure the heating unit (20). The connecting structure is simple and reliable, and there is no need to set up additional parts to secure the connecting brackets, which is advantageous for miniaturizing the aerosol generating device (100), saving parts, lowering costs, and improving the user experience.
[0118] Two connecting brackets and a heating member (22) jointly define a first receiving groove (20a), and a first air inlet section (100d) is defined and formed between the inner wall of the two connecting brackets and the heating member (22) and the outer wall of the heating member (22); a first guide groove extending along the diameter direction of the heating member (22) is installed in the connecting bracket located at the bottom of the heating member (22), and a second air inlet section (100e) is defined and formed between the groove wall of the first guide groove and the bottom of the aerosol generating product (200) contained within the first receiving groove (20a).
[0119] The extension length of the first guide groove is not limited, and it is sufficient to allow the airflow reaching the side away from the air discharge unit (12) of the first air inlet section (100d) to flow into the cross-sectional area of the aerosol generating product (200).
[0120] In some embodiments, with reference to FIGS. 2 and 3, the housing body (11) includes an outer case (111) and a mounting bracket (112), and the mounting bracket (112) is disposed within the outer case (111) and defines a mounting space (11a) and an opening (11b) communicating with the mounting space (11a) in common with the outer case (111).
[0121] At least a portion of the outer case (111) can function as an exterior part of the aerosol generating device (100), and the outer case (111) can facilitate the placement of the mounting bracket (112) and the heating unit (20).
[0122] In some embodiments, the aerosol generating product (200) protrudes out of the housing body (11). By setting the aerosol generating product (200) to protrude out of the housing body (11), fixed mounting with the air exhaust unit (12) is made convenient, and the temperature that the air exhaust unit (12) must withstand can be lowered, thereby extending the lifespan of the air exhaust unit (12).
[0123] In some other embodiments, the aerosol generating product (200) is located within the housing body (11). Since the aerosol generating product (200) is located within the housing body (11), the aerosol generating product (200) can be positioned as much as possible within the heating unit (20), thereby sufficiently heating the aerosol generating product (200) and increasing the utilization rate of the aerosol generating product (200).
[0124] In another embodiment, the cross-section of one end adjacent to the air discharge unit (12) of the aerosol generating product (200) lies in one plane with the cross-section of the housing body (11). Since the cross-section of one end adjacent to the air discharge unit (12) of the aerosol generating product (200) lies in one plane with the cross-section of the housing body (11), the aerosol generating product (200) can be positioned as much as possible within the heating unit (20), thereby sufficiently heating the aerosol generating product (200) and increasing the utilization rate of the aerosol generating product (200).
