Technical Field

[0001] This application relates to the field of atomization technology, and more particularly to an atomizer and an aerosol generating device. Background Technology

[0002] This section is intended to provide background or context for embodiments of this application. The description herein is not intended to imply that it is prior art simply because it is included in this section.

[0003] In related technologies, atomizers include atomizing cores, which are used to heat aerosol generation matrix to generate aerosols. During the process of atomizing aerosols generated by the atomizing core, problems such as insufficient aerosol quantity or burnt taste are prone to occur. These problems reduce the user experience and are urgent issues to be solved in this field. Therefore, how to improve the taste is an important research direction in this field. Utility Model Content

[0004] In view of this, the present application aims to provide an atomizer and aerosol generating device that can shorten the flow path of the aerosol generating matrix, increase the liquid supply speed, thereby increasing the amount of aerosol and improving the taste.

[0005] The first aspect of this application provides an atomizer, comprising:

[0006] The housing assembly has a mounting cavity and an exhaust passage;

[0007] An atomizing seat assembly having at least one liquid supply channel, the atomizing seat assembly being disposed within the mounting cavity to define at least a portion of the space of the mounting cavity as a liquid storage cavity;

[0008] An atomizing core is disposed within the atomizing seat assembly. The atomizing core is connected to the exhaust channel. The at least one liquid supply channel is located on one side of the atomizing core along its width direction. The liquid supply channel is connected to the liquid storage chamber and the atomizing core.

[0009] In some embodiments, a ventilation channel is formed between the atomizing seat assembly and the atomizing core, and the ventilation outlet of the ventilation channel is connected to the at least one liquid supply channel, through which airflow enters the liquid supply channel.

[0010] In some embodiments, the atomizing seat assembly has a liquid passage located on the bottom side of the atomizing core, and the liquid supply channel communicates with the atomizing core through the liquid passage.

[0011] In some embodiments, the bottom surface of the liquid passage has at least one flow guide surface, the at least one flow guide surface is obliquely distributed along the width direction of the atomizing core, and the end of the at least one flow guide surface near the atomizing core is lower than the end away from the atomizing core in the top-bottom direction.

[0012] In some embodiments, there are two liquid supply channels, which are respectively connected to opposite sides of the liquid passage along the width direction.

[0013] In some embodiments, the top portion of the atomizing core has an atomizing surface facing the exhaust channel, and in the top-to-bottom direction, the air exchange outlet is not lower than the bottom edge of the atomizing core.

[0014] In some embodiments, the atomizer assembly has an air intake channel that connects the atomizer core to external air, at least a portion of the air intake channel being located on one side of the atomizer core along its length, and at least a portion of the air intake channel extending along the length of the atomizer core.

[0015] In some embodiments, the atomizing seat assembly forms a baffle rib, which is disposed at the air outlet communicating with the air intake channel and the air exhaust channel.

[0016] In some embodiments, the atomizing seat assembly includes a first seat body and a base, the first seat body defining a portion of the space of the mounting cavity as the liquid storage cavity, at least a portion of the base body being disposed within the first seat body, and the first seat body defining at least a portion of the liquid supply channel;

[0017] The first seat is a flexible, one-piece structure.

[0019] The atomizer provided in this application embodiment has two advantages. First, at least a portion of the aerosol-generating matrix flows from one side of the atomizing core along its width direction to the atomizing core. This results in a shorter flow path for the aerosol-generating matrix, less resistance during its flow, and faster flow to the atomizing core, thus increasing the liquid supply speed. Second, compared to a liquid supply channel located on one side of the atomizing core along its length, the distribution of the liquid supply channel and the atomizing core along its width direction reduces the atomizer's volume, making it compact and enhancing its market competitiveness.

[0049] The embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but should not be used to limit the scope of this application.

[0050] In the description of the embodiments of this application, the orientation or positional relationship of the "width direction" is based on Figure 3 , Figure 6 , Figure 8 and Figure 13 The orientation or positional relationship shown, the orientation or positional relationship in the "length direction" is based on Figure 4 The orientation or positional relationship shown, the "top and bottom direction" orientation or positional relationship is based on Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 8 , Figure 10 , Figure 11 , Figure 13 and Figure 14The orientation or positional relationship shown is for illustrative purposes only and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the embodiments of this application.

[0051] The various specific technical features and embodiments described in the detailed embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features / embodiments can form different implementation methods. To avoid unnecessary repetition, the various possible combinations of various specific technical features / embodiments in this application will not be described separately. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0052] It should be noted that in this application, "at least one" refers to a quantity including one or more. "Multiple" refers to a quantity including two or more.

[0053] Research has found that the reason for insufficient aerosol quantity or burnt taste in related technologies is that the supply of aerosol generation matrix to the atomizing core is insufficient, which can easily lead to dry burning of the atomizing core, resulting in burnt taste and insufficient aerosol quantity.

[0054] Please see Figures 1 to 10 and Figures 13 to 15 This application provides an atomizer 10, including a housing assembly 1, an atomizing seat assembly 2, and an atomizing core 3. The housing assembly 1 has a mounting cavity 1a and an exhaust channel 1b; the atomizing seat assembly 2 has at least one liquid supply channel 2a, and the atomizing seat assembly 2 is disposed within the mounting cavity 1a to define at least a portion of the space of the mounting cavity 1a as a liquid storage cavity 1c; the atomizing core 3 is disposed within the atomizing seat assembly 2, the atomizing core 3 is connected to the exhaust channel 1b, and at least one liquid supply channel 2a is located on one side of the atomizing core 3 along its width direction.

[0055] The storage chamber 1c is used to store the aerosol generation matrix, which refers to the liquid fluid used for atomization to generate aerosols. For example, please refer to... Figure 3 The liquid supply channel 2a connects the liquid storage chamber 1c and the atomizing core 3. The liquid inlet channel is used to guide the aerosol generating matrix in the liquid storage chamber 1c to the atomizing core 3. The atomizing core 3 absorbs the aerosol generating matrix and heats and atomizes the aerosol generating matrix to generate aerosol.

[0056] Part of the space in the mounting cavity 1a is used to place components such as the atomizing seat assembly 2. The atomizing seat assembly 2 defines the other part of the space in the mounting cavity 1a as the liquid storage cavity 1c. The overall structure of the atomizer 10 is compact.

[0057] The outlet of exhaust channel 1b can be connected to the outside. The atomizing core 3 is connected to exhaust channel 1b, meaning that the aerosol generated by heating the atomizing core 3 can flow to exhaust channel 1b and then be discharged to the outside for user use through the outlet of exhaust channel 1b. For example, please refer to [link to example]. Figure 3 , Figure 4 and Figure 13 The exhaust channel 1b can extend along the top-bottom direction, so the flow direction of the aerosol within the exhaust channel 1b remains essentially unchanged, reducing aerosol loss during flow. This allows users to inhale a more concentrated aerosol, resulting in a better user experience. In other examples, the exhaust channel 1b may also have partial bends, or it may extend in a direction intersecting the top-bottom direction, where the top-bottom direction is perpendicular to the width direction of the atomizing core 3.

[0058] It is understandable that the width direction of the atomizer core 3 is the direction that intersects with the extension direction of the longest dimension of the atomizer core 3. The extension direction of the longest dimension of the atomizer core 3 is the length direction of the atomizer core 3. That is, the dimension of the atomizer core 3 along the width direction is smaller than the dimension of the atomizer core 3 along the length direction.

[0059] The atomizer core 3 can be a polyhedron, such as a cuboid. Taking the cuboid shape of the atomizer core 3 as an example, the direction in which the longest dimension of the atomizer core 3 extends is the length direction, and the width direction of the atomizer core 3 can be a direction perpendicular to the length direction of the cuboid.

[0060] At least one liquid supply channel 2a is located on one side of the atomizing core 3 along its width direction. This means that at least a portion of the aerosol generating matrix flows from one side of the atomizing core 3 along its width direction to the atomizing core 3. In this way, on the one hand, the flow path of the aerosol generating matrix is ​​shorter, the resistance encountered during its flow is smaller, and the aerosol generating matrix can flow to the atomizing core 3 more quickly. On the other hand, compared to placing the liquid supply channel 2a on one side of the atomizing core 3 along its length direction, the distribution of the liquid supply channel 2a and the atomizing core 3 along its width direction can reduce the volume of the atomizer 10, making the atomizer 10 compact and enhancing its market competitiveness.

[0061] The atomizer 10 provided in this application embodiment has two advantages. First, at least a portion of the aerosol-generating matrix flows from one side of the atomizing core 3 in the width direction to the atomizing core 3. This results in a shorter flow path for the aerosol-generating matrix, less resistance during its flow, and faster flow to the atomizing core 3, increasing the liquid supply speed and thus increasing the aerosol volume and improving the flavor. Second, compared to the liquid supply channel 2a being located on one side of the atomizing core 3 along its length direction, the liquid supply channel 2a and the atomizing core 3 are distributed along the width direction, reducing the volume of the atomizer 10 and making it more compact and competitive in the market.

[0062] Please see Figure 11 and Figure 12 This application also provides an aerosol generating device 100, including a power supply assembly 20 and an atomizer 10 as described in any embodiment of this application. The power supply assembly 20 supplies power to the atomizer 10. In some embodiments, the power supply assembly 20 and the atomizer 10 are detachably connected. In other embodiments, the power supply assembly 20 and the atomizer 10 may also be encapsulated in the same housing.

[0063] For example, the power supply component 20 is electrically connected to the conductive element 4, so that the power supply component 20 can supply power to the heating element through the conductive element 4. The power supply component 20 includes, but is not limited to, devices capable of providing electrical energy such as batteries. The power supply component 20 includes, but is not limited to, batteries. The battery can be a disposable battery or a rechargeable battery.

[0064] By way of example, the aerosol generating device 100 is a portable aerosol generating device 100. For example, the aerosol generating device 100 can be a handheld aerosol generating device 100. The outline shape of the aerosol generating device 100 can be generally elongated. This makes it easy for the user to hold the aerosol generating device 100.

[0065] During the use of the aerosol generating device 100, the user usually holds the aerosol generating device 100 with the bottom end of the aerosol generating device 100 close to the ground and the top end of the aerosol generating device 100 close to the sky. The bottom end is facing the ground, and the top end is facing the sky.

[0066] In some embodiments, please refer to Figure 4 and Figure 12 The atomizing core 3 has a liquid guiding surface 3b at its bottom end. The atomizer 10 includes a conductive element 4, a portion of which extends into the atomizing seat assembly 2 and abuts against the liquid guiding surface 3b. Thus, the overall structure of the atomizer 10 is compact. For an example, please refer to... Figure 4 There are two conductive elements 4, which are distributed at intervals along the length of the atomizing core 3, wherein the top and bottom directions are perpendicular to the length of the atomizing core 3.

[0067] The conductive component 4 transfers external electrical energy to the atomizing core 3. When energized, the atomizing core 3 heats the aerosol to generate a matrix, thus forming an aerosol.

[0068] The conductive component 4 abuts against the liquid guiding surface 3b, which supports the atomizing core 3, so that the atomizing core 3 is pressed tightly against the atomizing seat assembly 2, preventing the atomizing core 3 from being disturbed or displaced, improving the stability of the atomizing core 3, and also reducing the number of parts required to fix the atomizing core 3, thus reducing production costs.

[0069] The conductive component 4 is located inside the atomizer assembly 2. This reduces the space occupied by the conductive component 4 outside the atomizer assembly 2, which is beneficial for the atomizer 10 to be small and compact.

[0070] For example, the conductive element 4 can be a pin.

[0071] In one embodiment, the liquid storage chamber 1c is generally cylindrical, which allows for the storage of more aerosol generation matrix. In another embodiment, the liquid storage chamber 1c is generally duckbill-shaped, meaning that the outer contour surface of the housing assembly 1 is relatively flat, which saves more space and makes the atomizer 10 more compact.

[0072] In one embodiment, the atomizing core 3 includes a substrate and a heating element. The substrate has an atomizing surface 3a and a liquid guiding surface 3b. The heating element is disposed on the atomizing surface 3a. The substrate can guide the aerosol generation matrix to the atomizing surface 3a.

[0073] The matrix can be a porous structure, which may include wicking materials, including but not limited to one or more of porous fibers, porous ceramics, porous plastics, porous metals, cermets, or graphite-based materials. A porous structure refers to a structure with multiple interconnected pores that communicate with the outer surface of the matrix. The pores in a porous structure facilitate the temporary storage of the aerosol-generating matrix and also facilitate its flow. The pores can exhibit capillary action, guiding the aerosol-generating matrix to the heating surface. The hydraulic diameter is the ratio of four times the cross-sectional area to the perimeter. The cross-section refers to the section taken perpendicular to the streamlines of the fluid.

[0074] The pores in the porous structure are micropores, meaning that the hydraulic diameter of the pores is no greater than 100 μm (micrometers).

[0075] The specific material of the substrate is not limited. For example, the substrate can be made of conductive materials, such as conductive ceramics, nickel-chromium, stainless steel, or other metals or alloys. This eliminates the need for drilling holes in the substrate to run wires for power transfer, ensuring the integrity of the internal structure of the substrate and effectively guaranteeing the consistency of the atomizing core 3. Furthermore, it avoids the use of lead wires, reducing production costs and assembly difficulty.

[0076] In one embodiment, please refer to Figures 3 to 5 The atomizing surface 3a and the liquid guiding surface 3b are roughly parallel, so that the aerosol generation matrix can be guided relatively evenly from the liquid guiding surface 3b to the atomizing surface 3a, ensuring the atomization efficiency of the atomizing core 3.

[0077] In some cases, the aerosol generation matrix in the storage chamber gradually decreases with the increase in the number of times the user uses it, the cavity volume gradually increases, the air pressure in the storage chamber gradually decreases and forms a negative pressure, creating an air pressure difference with the outside atmosphere, which affects the flow of the aerosol generation matrix.

[0078] In some embodiments, please refer to Figure 3 , Figure 5 and Figure 7 A ventilation channel 2c is formed between the atomizing seat assembly 2 and the atomizing core 3. The ventilation outlet 2c2 of the ventilation channel 2c is connected to at least one liquid supply channel 2a, and the airflow enters the liquid supply channel 2a through the ventilation channel 2c. In other words, the aerosol generation matrix can be supplied with liquid from one side of the atomizing core 3 along the width direction via at least one liquid supply channel 2a, resulting in a faster liquid supply speed.

[0079] The airflow enters the liquid supply channel 2a through the ventilation channel 2c. In other words, the ventilation channel 2c guides the airflow, directing it unidirectionally into the liquid supply channel 2a.

[0080] The air exchange channel 2c guides the airflow to enter the liquid supply channel 2a in one direction, which means that the airflow can enter the liquid supply channel 2a through the air exchange channel 2c, while the aerosol generation matrix in the liquid supply channel 2a cannot flow out through the air exchange channel 2c.

[0081] After the airflow enters the liquid supply channel 2a, it forms bubbles and is discharged into the liquid storage chamber 1c through the liquid supply channel 2a, thereby compensating for the air pressure in the liquid storage chamber 1c and maintaining the air pressure in the liquid storage chamber 1c stable.

[0082] In some embodiments, please refer to Figure 3 and Figure 5 There are two liquid supply channels 2a, which are respectively connected to opposite sides of the liquid supply channel 2b along the width direction. For example, please refer to [further details]. Figure 3 and Figure 5 The two liquid supply channels 2a extend roughly along the top and bottom direction, and the liquid passage 2b extends roughly along the width direction. In other words, the two liquid supply channels 2a and the liquid passage 2b form a U-shaped structure.

[0083] In this embodiment, the aerosol generating matrix can be supplied simultaneously from both sides of the atomizing core 3 along its width direction via two liquid supply channels 2a, further increasing the liquid supply speed. Users can continuously inhale a rich-tasting aerosol, enhancing the user experience. Airflow can flow into the storage chamber 1c via the ventilation channel 2c and the liquid supply channel 2a, compensating for the air pressure within the storage chamber 1c and maintaining its stability. Furthermore, the air bubbles, during their flow, can carry the aerosol generating matrix towards the storage chamber 1c, ensuring smooth flow of the aerosol generating matrix.

[0084] It should be noted that the two liquid supply channels 2a are defined as the first liquid supply channel and the second liquid supply channel, respectively, with the first liquid supply channel connected to the ventilation channel 2c. On one hand, after the airflow enters the first liquid supply channel and forms bubbles, the aerosol-generating matrix in the second liquid supply channel is more abundant than that in the first liquid supply channel. A gravitational difference exists between the two liquid columns, causing the aerosol-generating matrix in the storage chamber 1c to flow first towards the second liquid supply channel and then through the liquid passage 2b back into the first liquid supply channel. On the other hand, the bubbles, during their flow, carry the aerosol-generating matrix in the first liquid supply channel towards the storage chamber 1c. Subsequently, the bubbles exit the first liquid supply channel. Since the aerosol-generating matrix in both liquid supply channels 2a is roughly the same, and there is no gravitational difference between the two liquid columns, the aerosol-generating matrix in the storage chamber 1c can flow through the two liquid supply channels 2a to the liquid passage 2b.

[0085] In other embodiments, there may be three, four or five liquid supply channels 2a, etc. The embodiments of this application do not limit the specific number of liquid supply channels 2a, as long as at least one liquid supply channel 2a is located on one side of the atomizing core 3 along the width direction.

[0086] In some embodiments, please refer to Figure 5 The atomizing core 3 has an atomizing surface 3a at its top, which faces the exhaust channel 1b. In the top-to-bottom direction, the air exchange outlet 2c2 is not lower than the bottom edge of the atomizing core 3. That is, the air exchange outlet 2c2 can be flush with the plane containing the liquid guiding surface 3b, or the air exchange outlet 2c2 can be located on the top side of the plane containing the liquid guiding surface 3b. For example, the air exchange outlet 2c2 can be located between the plane containing the atomizing surface 3a and the plane containing the liquid guiding surface 3b.

[0087] Specifically, the atomizing core 3 absorbs the aerosol-generating matrix through the liquid guiding surface 3b and guides it to the atomizing surface 3a. The atomizing surface 3a heats and atomizes the aerosol-generating matrix to generate aerosols. Please refer to [link to relevant documentation]. Figure 3 and Figure 4 The atomizing surface 3a facing the exhaust channel 1b means that the normal direction of the atomizing surface 3a is basically consistent with the normal direction of the inlet of the exhaust channel 1b. In this way, the aerosol generated by the atomizing surface 3a can directly enter the inlet of the exhaust channel 1b.

[0088] In this embodiment, the atomizing surface 3a faces the exhaust channel 1b, and the aerosol can flow directly out through the exhaust channel 1b for the user to inhale, which can reduce the loss of aerosol during the flow process. The user can inhale a more concentrated aerosol, resulting in a better user experience.

[0089] In another embodiment, the atomizing surface 3a faces the bottom side, that is, the atomizing surface 3a is formed at the bottom end of the atomizing core 3. In another embodiment, the atomizing surface 3a faces the peripheral side, that is, the atomizing surface 3a is formed on one side of the atomizing core 3 along the width direction, or on one side of the atomizing core 3 along the length direction.

[0090] For example, with the atomizing surface 3a facing upwards and the liquid guiding surface 3b facing downwards, i.e., the air exchange outlet 2c2 is higher than the liquid guiding surface 3b, bubbles can flow directly from the liquid supply channel 2a, which is connected to the air exchange channel 2c, into the liquid storage chamber 1c, without flowing through the liquid passage 2b to other liquid supply channels 2a. This prevents bubbles from flowing into the liquid passage 2b and remaining on and around the liquid guiding surface 3b, thus affecting the flow of liquid.

[0091] In some cases, when the atomizer's orientation changes, such as when the atomizer is inverted, more aerosol generation matrix will flow from the liquid guide surface to the atomizing surface, resulting in a large amount of aerosol generation matrix on and around the atomizing surface. This poses a risk of liquid explosion for users when drawing aerosols.

[0092] In some embodiments, please refer to Figure 5 The ventilation channel 2c has a ventilation inlet 2c1, which contacts the atomizing surface 3a. In this way, the excess aerosol generation matrix at the atomizing surface 3a flows directly through the ventilation inlet 2c1 to the ventilation channel 2c and then flows back into the liquid supply channel 2a, preventing liquid explosion.

[0093] In other embodiments, a plane perpendicular to the width direction of the atomizing core 3 is used as the projection plane, and the projection of the ventilation inlet 2c1 is located within the projection range of the atomizing core 3. In other words, in the top-bottom direction, the ventilation inlet 2c1 is not higher than the top edge of the atomizing core 3. In this way, during the process of the aerosol generating matrix flowing from the liquid guiding surface 3b to the atomizing surface 3a, part of the aerosol generating matrix can flow directly into the ventilation channel 2c through the ventilation inlet 2c1, preventing excessive aerosol generating matrix at the atomizing surface 3a and preventing liquid explosion problems.

[0094] In some embodiments, please refer to Figure 3 and Figure 8The atomizing seat assembly 2 has a liquid passage 2b located on the bottom side of the atomizing core 3. The liquid supply channel 2a connects to the atomizing core 3 through the liquid passage 2b. The bottom surface of the liquid passage 2b has at least one guide surface 2b1, which is inclined along the width direction of the atomizing core 3. The end of the guide surface 2b1 closest to the atomizing core 3 is lower than the end furthest from the atomizing core 3 in the top-to-bottom direction. The guide surface 2b1 guides the aerosol generating matrix, allowing it to flow more smoothly. In other words, the aerosol generating matrix flows sequentially through the liquid supply channel 2a and the liquid passage 2b to the liquid guiding surface 3b of the atomizing core.

[0095] The inclined distribution of the guide surface 2b1 means that the guide surface 2b1 is not parallel to the width direction of the atomizing core 3, that is, an angle is formed between the guide surface 2b1 and the width direction of the atomizing core 3. Please refer to [link / reference]. Figure 8 The end of the guide surface 2b1 near the atomizing core 3 is lower than the end away from the atomizing core 3, and the guide surface 2b1 has a height difference. In this way, the flow velocity of the aerosol generating matrix can be increased as it flows through the guide surface 2b1.

[0096] For example, please refer to Figure 5 The bottom surface of the liquid passage 2b near the atomizing core 3 is parallel to the width direction of the atomizing core 3. In this way, the aerosol generation matrix can flow smoothly to the atomizing core 3 after being accelerated by the guide surface 2b1.

[0097] In this embodiment, by setting the guide surface 2b1, the flow velocity of the aerosol generating matrix in the liquid passage 2b can be increased, allowing the aerosol generating matrix to flow smoothly to the guide surface 3b. For example, the atomizer 10 is inverted on a surface, with the guide surface 3b facing upwards and the atomizing surface 3a facing downwards. The aerosol generating matrix gathers towards the storage chamber 1c under gravity, and at least a portion of the liquid passage 2b is a cavity. When the user adjusts the atomizer 10's orientation, for example, by inverting the atomizer 10 so that the guide surface 3b faces downwards and the atomizing surface 3a faces upwards, the aerosol generating matrix in the storage chamber 1c flows back to the liquid passage 2b via the supply channel 2a. Under the guiding effect of the guide surface 2b1, it can quickly flow back to the guide surface 3b and its surrounding area, allowing the user to promptly draw in the aerosol.

[0098] In one embodiment, please refer to 3 and Figure 8 There are two guide surfaces 2b1, which are located on opposite sides of the liquid channel 2b along the width direction of the atomizing core 3. In this way, the aerosol generation matrix in the two liquid supply channels 2a can increase the flow velocity as it flows through the guide surfaces 2b1, thereby further improving the liquid supply efficiency.

[0099] In some embodiments, please refer to Figure 4 and Figure 6The atomizer assembly 2 has an air intake channel 2d that connects to the exhaust channel 1b and the atmosphere. At least a portion of the air intake channel 2d is located on one side of the atomizer core 3 along its length. Exemplarily, either a portion of the air intake channel 2d or the entire air intake channel 2d may be located on one side of the atomizer core 3 along its length. In this way, outside air can enter the atomizer 10 through the air intake channel 2d, and after flowing over the atomizing surface 3a, the airflow carries away the aerosol and flows out through the exhaust channel 1b for the user to inhale.

[0100] Please continue reading. Figure 4 The air intake channel 2d is located on one side of the atomizing core 3 along its length. This extends the airflow path, allowing the aerosol to mix thoroughly with the air and improving the taste. Furthermore, the ambient air is at a lower temperature than the atomizing core 3 when heating the aerosol-generating matrix. This lower temperature of the aerosol in the exhaust channel 1b further enhances the user experience.

[0101] In one embodiment, please refer to Figure 4 There are two air intake channels 2d, located on opposite sides of the atomizing core 3 along its length. This allows outside air to flow through the two air intake channels 2d to the atomizing surface 3a, increasing the air intake and resulting in a richer, fuller flavor of the aerosol.

[0102] In other embodiments, the air intake channel 2d may be one, three, four or five, etc. The embodiments of this application do not limit the specific number of air intake channels 2d, as long as at least one air intake channel 2d is located on one side of the atomizing core 3 along the length direction.

[0103] In one embodiment, the ventilation channel 2c is connected to the atmosphere through the air intake channel 2d. In this way, outside air can flow to the liquid storage chamber 1c through the air intake channel 2d and the ventilation channel 2c, thereby compensating for the air pressure in the liquid storage chamber 1c and maintaining the air pressure stability of the liquid storage chamber 1c.

[0104] In one embodiment, the ventilation channel 2c is a portion of the intake channel 2d.

[0105] In some embodiments, please refer to Figure 4 At least a portion of the air intake channel 2d extends along the length of the atomizing core 3. For example, either a portion of the air intake channel 2d extends along the length of the atomizing core 3, or the entire air intake channel 2d extends along the length of the atomizing core 3. This ensures that the flow path of the outside air is relatively straight, i.e., it flows along approximately the length, resulting in low flow resistance and a faster flow speed, allowing the user to promptly inhale a rich-tasting aerosol.

[0106] In some embodiments, please refer to Figure 5 and Figure 6The atomizing seat assembly 2 forms a baffle 241, which is located at the air outlet 2d1, which connects the air inlet channel 2d and the exhaust channel 1b. Outside air flows through the air outlet 2d1 to the atomizing surface 3a and its surrounding area. By setting the baffle 241, the outside air is diverted, thereby changing the direction and speed of the airflow and promoting the mixing of aerosol and air.

[0107] The specific shape of the deflector 241 is not limited. For example, the deflector 241 can be any one or a combination of rectangles, semicircles, serrations, or arcs. The number of deflectors 241 can be one or more.

[0108] In some embodiments, please refer to Figure 5 and Figure 6 Multiple baffles 241 are arranged at intervals along the width direction of the atomizing core 3. That is, the multiple baffles 241 divide the air outlet 2d1 into multiple airflow channels, allowing outside air to flow towards the atomizing surface 3a from different directions through these channels, further promoting thorough mixing of the aerosol and airflow. In other embodiments, the number of baffles 241 can also be one, with one baffle 241 dividing the air outlet 2d1 into two airflow channels along the width direction of the atomizing core 3.

[0109] For example, please continue reading Figure 5 and Figure 6 Two baffles 241 are spaced apart at the air outlet 2d1. That is, the two baffles 241 divide the air outlet 2d1 into three air outlet channels. The airflow can flow to the atomizing surface 3a from at least three directions through the three air outlet channels, thereby fully mixing with the aerosol. The user can then inhale the aerosol with a richer flavor.

[0110] In some embodiments, please refer to Figure 5 and Figure 6 The outer peripheral surface of the atomizing seat assembly 2 forms multiple capillary reservoirs 21a, at least one of which is connected to the exhaust channel 1b. In the top-to-bottom direction, the capillary reservoir 21a is lower than the bottom end of the exhaust channel 1b. The capillary reservoir 21a has capillary force, thus enabling it to store the aerosol generation matrix. Exemplarily, when the aerosol generation matrix in the reservoir chamber 1c is insufficient, the aerosol generation matrix in the capillary reservoir 21a can flow to the atomizing core 3 to generate aerosol for the user to inhale.

[0111] As an example, the number of capillary reservoirs 21a can be two, three, four, or five, etc. The specific number of capillary reservoirs 21a is not limited in the embodiments of this application.

[0112] In this embodiment, on the one hand, the capillary reservoir 21a can increase the liquid storage capacity of the atomizer 10, allowing the user to draw more aerosols. On the other hand, some aerosols mix with water vapor in the airflow within the exhaust channel 1b to form condensate. The capillary reservoir 21a is connected to the exhaust channel 1b and is lower than the bottom of the exhaust channel 1b, so that the condensate remaining in the exhaust channel 1b can flow to the capillary reservoir 21a, preventing the condensate from flowing back onto the atomizing surface 3a and affecting the atomization efficiency.

[0113] In some embodiments, please refer to Figure 5 and Figure 7 The atomizing seat assembly 2 forms a liquid guiding groove 2e, which connects the exhaust channel 1b and the topmost capillary liquid storage tank 21a. The liquid guiding groove 2e has a guiding function, which can guide the condensate in the exhaust channel 1b to the topmost capillary liquid storage tank 21a, preventing the condensate from flowing back onto the atomizing surface 3a.

[0114] It is important to understand that in some cases, when there is a large amount of aerosol-generating matrix in the storage chamber 1c, some of the aerosol-generating matrix will flow towards the capillary storage tank 21a. The aerosol-generating matrix will preferentially flow towards the bottom capillary storage tank 21a. This separates the condensate and the aerosol-generating matrix, ensuring the taste of the aerosol.

[0115] In some embodiments, please refer to Figure 6 The outer peripheral surface of the atomizing seat assembly 2 forms a capillary connecting groove 21b, which connects two adjacent capillary storage tanks 21a. In other words, the aerosol generating matrix can flow through the capillary connecting groove 21b within the two adjacent capillary storage tanks 21a.

[0116] For example, please refer to Figure 6 The atomizing seat assembly 2 has four capillary reservoirs 21a, with the topmost capillary reservoir 21a connected to the exhaust channel 1b. When the aerosol generating matrix fills the bottom capillary reservoir 21a, excess aerosol generating matrix can flow through the capillary connecting channel 21b to the adjacent capillary reservoir 21a, and sequentially flow into the other two capillary reservoirs 21a except for the topmost one.

[0117] In some embodiments, please refer to Figures 3 to 10 The atomizing seat assembly 2 includes a first seat body 21 and a base 23. The first seat body 21 defines a portion of the space of the mounting cavity 1a as a liquid storage cavity 1c. At least a portion of the base 23 is disposed within the first seat body 21. The first seat body 21 defines at least a portion of the liquid supply channel 2a. A capillary liquid storage groove 21a is formed on the outer peripheral surface of the first seat body 21. At least one of the base 23 and the second seat body 22 forms a capillary liquid storage space 22a. The bottommost capillary liquid storage groove 21a communicates with the capillary liquid storage space 22a.

[0118] For example, the first seat 11 may define a portion of the liquid supply channel 2a, or the first seat 11 may define the entire liquid supply channel 2a.

[0119] For example, please continue reading Figures 3 to 10 The atomizing seat assembly 2 also includes a second seat 22, at least a portion of which is disposed within the first seat 21. The first seat 21 and the second seat 22 together define a liquid supply channel 2a and a liquid passage channel 2b. The first seat 21, the second seat 22, and the base 23 can be designed and manufactured separately, thus reducing manufacturing difficulty. The first seat 21 provides installation space for the second seat 22, and the second seat 22 provides installation space for the base 23. During the assembly of the atomizing seat assembly 2, the second seat 22 can be assembled into the first seat 21 first, and then the base 23 can be assembled into the second seat 22. Alternatively, the base 23 can be assembled into the second seat 22 first, and then the second seat 22 can be assembled into the first seat 21. Finally, the entire atomizing seat assembly 2 is assembled with the housing assembly 1, which is convenient and quick.

[0120] The formation of a capillary liquid storage space 22a in at least one of the base 23 and the second seat body 22 means that: the base 23 may form a capillary liquid storage space 22a, the second seat body 22 may form a capillary liquid storage space 22a, or both the base 23 and the second seat body 22 may form a capillary liquid storage space 22a.

[0121] Please see Figure 5 , Figure 9 and Figure 10 The bottommost capillary reservoir 21a is connected to the capillary reservoir space 22a. The capillary reservoir space 22a has capillary force, thus enabling it to store the aerosol generation matrix. The aerosol generation matrix in the bottommost capillary reservoir 21a can flow into the capillary reservoir space 22a, which uses capillary force to lock in the aerosol generation matrix, preventing it from leaking out.

[0122] In one embodiment, please refer to Figure 9 and Figure 10 The second seat 22 has multiple first partition walls 221, and a capillary liquid storage space 22a is formed between two adjacent first partition walls 221. The base 23 has multiple second partition walls 232, and a capillary liquid storage space 22a is formed between two adjacent second partition walls 232. In other words, there are multiple capillary liquid storage spaces 22a, which can increase the liquid storage capacity and capillary action, resulting in a better seepage prevention effect.

[0123] In some embodiments, please refer to Figure 10The base 23 has a spherical wall 231 protruding towards the top, and the spherical wall 231 forms a plurality of air inlets 231a. The capillary liquid storage space 22a of the base 23 is located on the outer periphery of the spherical wall 231. The air inlets 231a are part of the air intake channel 2d.

[0124] In one embodiment, please refer to Figure 10 In the top-to-bottom direction, the spherical wall 231 protrudes from the second spacer wall 232 of the base 23. Thus, the aerosol-generating matrix within the capillary reservoir space 22a is difficult to flow towards the spherical wall 231.

[0125] In some embodiments, please refer to Figure 5 and Figure 8 The atomizing seat assembly 2 includes multiple capillary columns 242, which are disposed within the liquid passage 2b. The space between two adjacent capillary columns 242 is used to store the aerosol generation matrix.

[0126] For example, please continue reading Figure 5 All capillary columns 242 are located on the side of the atomizing core 3 closest to the liquid guiding surface 3b. With the plane perpendicular to the top and bottom as the projection plane, the projection of all capillary columns 242 lies within the projection range of the atomizing core 3. The space between two adjacent capillary columns 242 possesses capillary force, which can lock the aerosol generating matrix flowing through the capillary columns 242. This ensures that the liquid guiding surface 3b and its surrounding area are always filled with the aerosol generating matrix. The liquid guiding surface 3b can continuously guide the aerosol generating matrix to the atomizing surface 3a, preventing unsaturated aerosol generating matrix at the atomizing surface 3a, which would generate a burnt-smelling aerosol and negatively impact the user experience.

[0127] In some embodiments, please refer to Figure 3 and Figure 4 The first seat 21 is a flexible, one-piece structure, and the second seat 22 and the housing assembly 1 are both interference-fitted with the first seat 21. The first seat 21 is capable of elastic deformation that is bendable, foldable, torsional, compressible, and / or stretchable. The first seat 21, the second seat 22, and the housing assembly 1 are all in flexible contact. On the one hand, utilizing the elastic deformation characteristics of the first seat 21, vibrations transmitted to the second seat 22 and the housing assembly 1 can be reduced, preventing damage to the second seat 22 and the housing assembly 1 and providing good protection. On the other hand, the first seat 21 seals against the second seat 22 and the housing assembly 1, not only providing a good sealing effect and preventing aerosol generation matrix or aerosol from seeping out of the gaps, thus improving the sealing performance of the atomizer 10, but also reducing the required sealing structure, lowering assembly difficulty, and reducing production costs.

[0128] In one embodiment, please refer to Figure 3 and Figure 4The first housing 21 is interference-fitted with the atomizer core 3. This not only reduces vibrations transmitted to the atomizer core 3, preventing damage and providing better protection, but also reduces the need for a sealing structure between the atomizer core 3 and the first housing 21, further simplifying assembly and reducing production costs.

[0129] In one embodiment, the first base 21 is a one-piece molded structure. For example, the first base 21 can be a one-piece structure molded using processes such as injection molding or compression molding.

[0130] The first seat 21 can be made of flexible materials, such as rubber and / or silicone.

[0131] In other embodiments, please refer to Figure 13 and Figure 14 The atomizing seat assembly 2 includes a first sealing element 25, which includes a first side wall 251 and a peripheral wall 252. The peripheral wall 252 surrounds the periphery of the first side wall 251. The first side wall 251 is stacked on the top surface of the first seat body 21. The first side wall 251 forms a liquid inlet 251a, which connects to the liquid supply channel 2a. The peripheral wall 252 is sandwiched between the first seat body 21 and the cavity wall surface of the mounting cavity 1a.

[0132] Please continue reading. Figure 14 The first sidewall 251 can be roughly plate-shaped, and the outer wall 252 can be roughly annular. The outer wall 252 is sealed and clamped between the cavity wall surface of the mounting cavity 1a and the first seat 21. That is, the force between the cavity wall surface of the mounting cavity 1a and the first seat 21 causes the outer wall 252 to undergo elastic deformation, thereby sealing the gap between the cavity wall surface of the mounting cavity 1a and the first seat 21. The outer wall 252 plays a sealing role, which can prevent the aerosol generation matrix from seeping out from between the first seat 21 and the cavity wall surface of the mounting cavity 1a, thus improving the sealing performance of the atomizer 10.

[0133] Please see Figure 13 The first sidewall 251 is stacked on the side of the first seat 21 facing the liquid storage cavity 1c to enhance the connection stability between the first seat 21 and the first seal 25. Furthermore, the liquid inlet 251a faces the liquid supply channel 2a, so that the aerosol generating matrix in the liquid storage cavity 1c can flow directly to the liquid supply channel 2a through the liquid inlet 251a, reducing the flow resistance of the aerosol generating matrix.

[0134] The first sealing element 25 can be made of a flexible material. That is, the outer wall 252 has flexible contact with the first seat 21 and the cavity wall of the mounting cavity 1a. In this way, the vibration transmitted between the first seat 21 and the housing assembly 1 can be reduced, preventing damage to the first seat 21 and the housing assembly 1, and providing better protection.

[0135] The specific material of the first sealing element 25 is not limited; for example, it may be made of flexible materials such as rubber and / or silicone.

[0136] In one embodiment, the first sealing element 25 is a one-piece molded structure. For example, the first sealing element 25 can be a one-piece structure molded using processes such as injection molding or compression molding.

[0137] In one embodiment, please refer to Figure 14 The outer peripheral surface of the outer wall 252 has multiple annular protrusions 254, which serve as a multi-layer seal to improve the sealing performance of the first seal 25.

[0138] In other embodiments, please refer to Figure 13 and Figure 14 The first sealing element 25 includes an inner wall 253, which is sandwiched between the exhaust channel 1b and the first seat 21. The inner wall 253 is sealed between the exhaust channel 1b and the first seat 21; that is, the force between the exhaust channel 1b and the first seat 21 causes the inner wall 253 to undergo elastic deformation, thereby sealing the gap between the exhaust channel 1b and the first seat 21. The inner wall 253 acts as a seal, preventing aerosol from seeping out from between the first seat 21 and the exhaust channel 1b, and reducing aerosol loss.

[0139] In other embodiments, please refer to Figure 13 and Figure 15 The atomizer assembly 2 includes a second seal 26 surrounding the periphery of the atomizing core 3. The second seal 26 includes a clearance opening 26a and an annular wall 261. The clearance opening 26a faces the exhaust channel 1b, and at least a portion of the atomizing surface 3a is located within the clearance opening 26a. The annular wall 261 is sandwiched between the atomizing core 3 and the first seat 21. The annular wall 261 seals between the atomizing core 3 and the first seat 21; that is, the force between the atomizing core 3 and the first seat 21 causes the annular wall 261 to undergo elastic deformation, sealing the gap between them. The annular wall 261 provides a sealing function, preventing the aerosol generation matrix from seeping out from between the atomizing core 3 and the first seat 21, thus improving the sealing performance of the atomizer 10.

[0140] The fact that the clearance opening 26a faces the exhaust channel 1b means that the normal direction of the clearance opening 26a is basically consistent with the normal direction of the inlet of the exhaust channel 1b. The clearance opening 26a connects to the exhaust channel 1b, and the aerosol can flow directly to the exhaust channel 1b through the clearance opening 26a, which can reduce the loss of aerosol during the flow process.

[0141] The second seal 26 can be made of a flexible material. That is, the first seat 21 and the atomizing core 3 are in flexible contact with the annular wall 261, which can reduce the vibration transmitted to the atomizing core 3, prevent damage to the atomizing core 3, and play a better protective role.

[0142] The specific material of the second seal 26 is not limited; for example, it can be made of flexible materials such as rubber and / or silicone.

[0143] In one embodiment, the second seal 26 is a one-piece molded structure. For example, the second seal 26 can be a one-piece structure molded using processes such as injection molding or compression molding.

[0144] In other embodiments, please refer to Figure 13 The atomizing seat assembly 2 includes a first sealing ring 27, which seals against the wall surface of the second seat body 22 and the mounting cavity 1a. The first sealing ring 27 is located on the side of the first sealing element 25 away from the liquid storage cavity 1c. In this way, the first sealing element 25 and the first sealing ring 27 provide a multi-layer seal, which can effectively prevent the aerosol generation matrix from seeping outward and further improve the sealing performance of the atomizer 10.

[0145] In other embodiments, please refer to Figure 13 The atomizing seat assembly 2 includes a second sealing ring 28, which seals against the space between the second seat body 22 and the base 23. This prevents the aerosol generation matrix in the capillary reservoir space 22a from leaking out, further improving the sealing performance of the atomizer 10.

[0146] In some embodiments, the housing assembly 1 is a transparent structure.

[0147] The specific material of the housing component 1 is not limited. For example, the housing component 1 can be made of PCTG material, which has the characteristics of high transparency and excellent impact resistance. This makes it easy for the user to observe the remaining amount of aerosol generation matrix in the liquid storage chamber 1c.

[0148] In some embodiments, please refer to Figure 1 and Figure 2 The housing assembly 1 includes a suction nozzle 11 and a bottom cover 12. The suction nozzle 11 forms an exhaust channel 1b, an open cavity, and a mounting port communicating with the open cavity. The bottom cover 12 closes the mounting port to define the open cavity as a mounting cavity 1a. Thus, the user can suction aerosol through the suction nozzle 11. The bottom cover 12 seals the mounting port to prevent external impurities from entering the mounting cavity 1a.

[0149] The specific materials of the nozzle 11 and the bottom cover 12 are not limited. For example, both the nozzle 11 and the bottom cover 12 can be made of plastic.

[0150] In another embodiment, the bottom cover 12 is made of SPCC (cold-rolled carbon structural steel), so that the bottom cover 12 has the characteristics of easy processing and low cost, and also has good impact resistance.
