[0031] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, four, etc., unless otherwise explicitly specified.

[0034] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

[0036] Figures 1 to 3 An electronic atomizing device 1 according to a first embodiment of the present invention is shown. This device 1 is used to contain an aerosol generating matrix and heat and atomize the aerosol generating matrix upon energization. The aerosol generating matrix includes, but is not limited to, materials used for medical, health, and cosmetic purposes.

[0037] The shape of the electronic atomizing device 1 is not limited; for example, it can have various shapes such as square column, cylindrical, elliptical column, racetrack-shaped column or polygonal column.

[0038] The electronic atomizing device 1 includes a housing 10 and an atomizing component 20 disposed within the housing 10. A liquid storage chamber 110 is formed within the housing 10. The atomizing component 20 includes an atomizing core 30 in fluid communication with the liquid storage chamber 110. The atomizing core 30 is used to heat and atomize the aerosol generation matrix stored in the liquid storage chamber 110 after being powered on. In some embodiments, the atomizing component 20 further includes a mounting base assembly 40, within which an atomizing chamber 43 is formed, and the atomizing core 30 is at least partially disposed within the atomizing chamber 43.

[0039] In addition, an airflow channel 101 is formed inside the outer shell 10. The airflow channel 101 includes an air inlet 120, an air outlet 111, and an air intake 112, which are sequentially connected. The air inlet 120, the atomizing chamber 43, the air outlet 111, and the air intake 112 are usually located at one end of the outer shell 10 (shown as the upper end in the figure). The air inlet 120 can be located at any position on the outer shell 10, such as on the bottom wall, side wall, or top wall of the outer shell 10. The atomizing core 30 is connected to the airflow channel 101 for air guidance. When the user inhales through the air intake 112, outside air enters through the air inlet 120, flows through the atomizing core 30, and carries the aerosol generated by the atomizing core 30 through the air outlet 111 to the air intake 112 for the user to inhale.

[0040] Furthermore, the electronic atomizing device 1 may also include a battery 50 and a control circuit disposed in the housing 10. The atomizing core 30 and the battery 50 are electrically connected to the control circuit. The control circuit can control the battery 50 to supply power to or de-supply the atomizing core 30, and can also control the power of the battery 50 supplying power to the atomizing core 30, etc.

[0041] The arrangement of the battery 50 and the liquid storage chamber 110 within the housing 10 can be designed according to the shape of the housing 10. The housing 10 is defined as having two perpendicular directions: a length direction X, a width direction Y, and a height direction Z, where the height direction Z is the extension direction of the venting channel 111. If the housing 10 has a large dimension in the length direction X, for example, if the housing 10 has a rectangular or near-rectangular cross-section, the battery 50 and the liquid storage chamber 110 can be arranged at least partially side-by-side along the length direction X. Of course, in other embodiments, the battery 50 and the liquid storage chamber 110 can also be arranged side-by-side in the height direction Z.

[0042] In some embodiments, the electronic atomizing device 1 may further include an airflow sensor 60 disposed in the housing 10. The airflow sensor 60 is electrically connected to the control circuit and communicates with the airflow channel 101. When the user begins to inhale, the airflow sensor 60 senses the change in air pressure and activates the battery 50 to power the atomizing core 30 through the control circuit, thereby atomizing the aerosol generation matrix in the liquid storage chamber 110.

[0043] like Figures 2 to 7As shown, the atomizing core 30 is cylindrical, for example. The atomizing core 30 is disposed laterally within the housing 10, and its axial direction may be perpendicular to the axial direction of the air outlet channel 111. Of course, in other embodiments, an angle may be formed between the axial direction of the atomizing core 30 and the axial direction of the air outlet channel 111. At least one end of the atomizing core 30 is in fluid communication with the liquid storage chamber 110; preferably, both ends of the atomizing core 30 are in fluid communication with the liquid storage chamber 110 for better liquid guiding performance.

[0044] The atomizing core 30 includes a support member 33, a flexible porous liquid guiding member 31 enclosing the support member 33, and a heating element 32. The support member 33 is rigid and is used to support the liquid guiding member 31. The liquid guiding member 31 is in fluid communication with the liquid storage chamber 110 and can draw the aerosol generating matrix from the liquid storage chamber 110 through capillary force and transport the aerosol generating matrix to the heating element 32. The heating element 32 heats the aerosol generating matrix after being energized.

[0045] The portion of the atomizing core 30 equipped with the heating element 32 is disposed in the atomizing chamber 43, so that the aerosol generated after the heating element 32 is heated and atomized can be output through the air outlet channel 111. The two ends of the atomizing core 30 are located outside the atomizing chamber 43 to facilitate fluid communication with the liquid storage chamber 110.

[0046] In some embodiments, the atomizing core 30 further includes two electrode leads 34 respectively connected to both ends of the heating element 32. The heating element 32 is electrically connected to the control circuit through the two electrode leads 34.

[0047] The liquid guiding component 31 is made of a soft, porous material. In some embodiments, the liquid guiding component 31 is made of cotton or fiber materials, such as bulk cotton or woven cotton. The material of the liquid guiding component 31 may include one or more fiber materials such as cotton, linen, viscose, polyester, and polyimide. Exemplarily, the liquid guiding component 31 is woven from several yarns, the diameter of which may be 0.01mm-1mm, or the fineness of which may be 10-200 count (e.g., 10-60 count), and different yarn fineness can be selected according to different physical properties of the liquid.

[0048] The liquid guiding component 31 can be tightly wrapped around the outer surface (outer cylindrical surface) of the support component 33. The axial length of the liquid guiding component 31 can be equal to, less than or greater than the axial length of the support component 33.

[0049] The heating element 32 can be disposed on the inner or outer side of the liquid guiding member 31, or it can be interwoven with the liquid guiding member 31. In some embodiments, the heating element 32 is tightly wrapped around the outer surface (outer cylindrical surface) of the liquid guiding member 31, which can be a mesh, array, or fabric formed of conductive wires or conductive sheets. The material of the heating element 32 can be metals or alloys such as iron-chromium-aluminum, nickel-chromium, titanium wire, and nickel wire. Exemplarily, the heating element 32 is made of one or more metal conductive wires wound around the outer surface of the liquid guiding member 31, and the diameter of each metal conductive wire can be 0.08mm-0.3mm.

[0050] The support member 33 can be made of materials with a certain mechanical strength, such as metal, ceramic, glass, or engineering plastic. For example, the support member 33 can be a metal tube (preferably stainless steel), which can be manufactured by processes such as extrusion molding or powder metallurgy. Another example is that the support member 33 can be a ceramic rod (e.g., a quartz rod), which can be formed by processes such as injection molding or extrusion molding.

[0051] The support member 33 can be a hollow tube or a solid rod. In this embodiment, the support member 33 is a hollow tube with a liquid guiding channel 330 formed axially inside. The two ends of the liquid guiding channel 330 are in fluid communication with the liquid storage chamber 110. At least one liquid outlet hole 331 is also formed through the side wall of the support member 33. The aerosol generating matrix entering from both ends of the liquid guiding channel 330 can flow out to the liquid guiding member 31 through the at least one liquid outlet hole 331. Preferably, there are multiple liquid outlet holes 331, which can be evenly distributed in the circumferential direction of the support member 33, which is beneficial for the uniform flow of the aerosol generating matrix in the liquid guiding channel 330 to the liquid guiding member 31.

[0052] The mounting base assembly 40 is disposed in the housing 10 and can seal the lower opening of the liquid storage chamber 110. The mounting base assembly 40 also forms two liquid discharge channels 44, and the two ends of the atomizing core 30 are respectively fluidly connected to the liquid storage chamber 110 through the two liquid discharge channels 44.

[0053] In some embodiments, the mounting base assembly 40 may include a base 41 and a top seat 42 that cooperates with the base 41. The base 41 and the top seat 42 cooperate to form an atomizing chamber 43. Two mounting holes 45 are also formed at both ends of the mounting base assembly 40, which connect the atomizing chamber 43 to the outside. The middle part of the atomizing core 30 is disposed in the atomizing chamber 43, and both ends of the atomizing core 30 are respectively disposed in the two mounting holes 45.

[0054] The base 41 and the top seat 42 are located on both sides of the atomizing core 30, and are pressed and fixed to the atomizing core 30 from both sides. Specifically, the base 41 is located on the lower side of the atomizing core 30 (i.e., the side away from the inhalation port 112), and the top seat 42 is located on the upper side of the atomizing core 30.

[0055] In some embodiments, the mounting base assembly 40 includes two mounting portions 46 that respectively mate with both ends of the atomizing core 30, and the two mounting portions 46 are located at both ends of the atomizing chamber 43. Each mounting portion 46 can be formed by the mating of a base 41 and a top seat 42. Each mounting portion 46 has a first pressing surface 411 and a second pressing surface 421, which press and fix the atomizing core 30 from both sides of the atomizing core 30.

[0056] Specifically, the base 41 has a first pressing surface 411, and the top seat 42 has a second pressing surface 421. The first pressing surface 411 and the second pressing surface 421 cooperate to define at least a portion of the mounting hole 45. The two ends of the atomizing core 30 are respectively interference-fitted into the two mounting holes 45, thereby achieving the fixation of the atomizing core 30 and the fluid communication between the atomizing core 30 and the liquid storage chamber 110.

[0057] The shapes of the first pressing surface 411 and the second pressing surface 421 are adapted to the shape of the atomizing core 30 so as to better press and fix the atomizing core 30. For example, in this embodiment, the shape of the atomizing core 30 is cylindrical, the first pressing surface 411 and the second pressing surface 421 are two semi-circular surfaces, and the first pressing surface 411 and the second pressing surface 421 are fitted together to form a roughly cylindrical mounting hole 45.

[0058] The diameter D1 of the mounting hole 45 (i.e., the diameter of the first pressing surface 411 and the diameter of the second pressing surface 421) is greater than or equal to the outer diameter D2 of the support member 33. In addition, the diameter D1 of the mounting hole 45 is smaller than the outer diameter of the liquid guide member 31 in its natural state (unpressed). Thus, when both ends of the atomizing core 30 are assembled into the mounting hole 45, the liquid guide member 31 will be squeezed by the first pressing surface 411 and the second pressing surface 421, causing the outer diameter of the atomizing core 30 to shrink, and the two ends of the atomizing core 30 to be tightly pressed and fixed. This can reduce the leakage of the aerosol generation matrix in the liquid storage chamber 110 caused by the fit gap between the mounting hole 45 and the atomizing core 30.

[0059] In some embodiments, the axial length L of the first pressing surface 411 and the second pressing surface 421 can be 0.5mm to 3mm. The diameter D1 of the mounting hole 45 is 0 to 2mm larger than the outer diameter D2 of the support member 33, so that the outer diameter of the atomizing core 30 after being pressed by the first pressing surface 411 and the second pressing surface 421 is reduced by 0.2mm to 0.8mm, which can achieve better fixation and leakage prevention while ensuring the liquid guiding performance.

[0060] In some embodiments, each assembly part 46 further includes a supporting part 412. The two supporting parts 412 of the two assembly parts 46 are respectively located at both ends of the atomizing core 30. Each supporting part 412 abuts against a portion of the end face at both ends of the atomizing core 30, thereby holding and fixing the atomizing core 30 between the two supporting parts 412.

[0061] The two end faces of the support member 33 can respectively abut against the two abutment portions 412. Alternatively, the two end faces of the support member 33 can also be spaced apart from the two abutment portions 412, that is, the length of the support member 33 is less than the distance between the two abutment portions 412, the length of the liquid guide member 31 is greater than the length of the support member 33, and the two ends of the atomizing core 30 abut against the two abutment portions 412 through the liquid guide member 31.

[0062] Two abutment portions 412 protrude from the outer sides of the two mounting holes 45 (i.e., the side away from the atomizing chamber 43). Specifically, the abutment portions 412 can be formed on the base 41, with each abutment portion 412 protruding from the end face of each first pressing surface 411 away from the atomizing chamber 43. The shape of the abutment portion 412 can be adapted to the shape of the first pressing surface 411; for example, the abutment portion 412 can be a semi-circular ring. Of course, in other embodiments, the abutment portions 412 can also be formed on the top seat 42, with each abutment portion 412 protruding from the end face of each second pressing surface 421 away from the atomizing chamber 43.

[0063] In some embodiments, the height of the abutment portion 412 is not higher than the lowest point of the solid material of the support member 33, or in other words, the abutment portion 412 abuts against a portion of the end face of the liquid guide member 31 but not against the end face of the support member 33. Thus, on the one hand, the abutment portion 412 will not obstruct the liquid guide member 31 from absorbing liquid from its end; on the other hand, since the abutment portion 412 does not abut against the end face of the rigid support member 33, assembly difficulties will not occur due to manufacturing errors causing an overly tight fit between the support member 33 and the abutment portion 412.

[0064] The liquid discharge channel 44 is located at the bottom of the liquid storage chamber 110, that is, the liquid discharge channel 44 is located at the end of the liquid storage chamber 110 away from the air intake 112. Alternatively, it can be said that the bottom wall surface 440 of the liquid discharge channel 44 defines the bottom surface of the liquid storage chamber 110.

[0065] In some embodiments, the bottom wall surface 440 of the lower liquid channel 44 may include a base 442 and a recessed portion 441 formed by the base 442, the recessed portion 441 corresponding to the end of the atomizing core 30. By providing the recessed portion 441, when the aerosol generating matrix in the liquid storage chamber 110 is nearly depleted, the aerosol generating matrix on the base 442 can flow towards the recessed portion 441 under the action of gravity and collect there, and then flow towards the atomizing core 30, thereby improving the utilization rate of the aerosol generating matrix and reducing waste. The cross-section of the recessed portion 441 may be V-shaped or V-shaped.

[0066] There are two bases 442, located on opposite sides of the recess 441 along the width direction Y. The recess 441 includes two guiding surfaces 4411 connected to the two bases 442 respectively, and a converging surface 4412 located between the two guiding surfaces 4411. The two guiding surfaces 4411 and the converging surface 4412 form a V-shaped or V-shaped structure. The guiding surfaces 4411 may include inclined planes and / or arcuate surfaces; of course, the guiding surfaces 4411 may also have other shapes, as long as they can guide the aerosol generating matrix on the bases 442 to the converging surface 4412 under the action of gravity. Similarly, the shape of the converging surface 4412 is not limited, and it may also include planes and / or arcuate surfaces.

[0067] The lowest point of the recess 441 (or the lowest point of the confluence surface 4412) should preferably not be higher than the lowest point of the solid material of the support member 33. In this way, the aerosol generating matrix in the recess 441 can be adsorbed to the maximum extent by the end of the liquid guiding member 31, thereby further improving the utilization rate of the aerosol generating matrix.

[0068] The base 442 can be a horizontally arranged plane. When the electronic atomizing device 1 is placed at an angle, the aerosol generating matrix on the base 442 can flow towards the recess 441 under the action of gravity. Of course, the base 442 can also have an inclination that guides the flow-guiding surface 4411. Specifically, the base 442 can include a plane and / or an arc surface that are inclined towards the flow-guiding surface 4411. This can help guide the aerosol generating matrix on the base 442 to flow towards the recess 441.

[0069] During assembly, the atomizing core 30 can be placed on the base 41 first, and then the top seat 42 can be pressed from the other side of the atomizing core 30. The base 41 and the top seat 42 can be tightly connected by interference fit or snap-fit ​​connection.

[0070] The materials of the base 41 and the top seat 42 are not limited; for example, they can be made of plastic or silicone. In some embodiments, one of the base 41 and the top seat 42 can be made of plastic and the other of silicone. For example, the base 41 can be made of plastic and the top seat 42 can be made of silicone, or the base 41 can be made of silicone and the top seat 42 can be made of plastic. This can ensure strength while also providing good sealing performance.

[0071] Of course, in other embodiments, the base 41 and the top seat 42 may also be made of plastic, and can be sealed by additional sealing components. Alternatively, the base 41 and the top seat 42 may also be made of silicone material with a certain hardness, such as silicone material with a hardness of 50 to 70 degrees, to ensure that the fixing seat assembly 40 has a certain structural strength.

[0072] In some embodiments, the top seat 42 may include a main body 422 and an extension 423 extending upward from the upper end of the main body 422. The main body 422 is cylindrical with an open lower end, and the main body 422 cooperates with the base 41 to form an atomizing chamber 43.

[0073] The outer wall surface of the main body 422 can be sealed with the inner wall surface of the outer casing 10, thereby sealing the lower opening of the liquid storage cavity 110. That is, the upper end surface of the main body 422 defines the bottom surface of the liquid storage cavity 110. The liquid discharge channel 44 is formed on the upper end surface of the main body 422.

[0074] The length of the extension 423 is smaller than that of the main body 422, and the two liquid discharge channels 44 are located on both sides of the extension 423 along the length direction X. The outer wall surfaces of the extension 423 on both sides in the width direction Y can seal against the inner wall surface of the outer casing 10, which helps to improve the sealing effect on the liquid storage chamber 110. Of course, in other embodiments, the outer wall surfaces of the extension 423 on both sides in the width direction Y can also be spaced apart from the inner wall surface of the outer casing 10.

[0075] An axial through-hole 4230 is formed on the extension 423 to connect the atomizing chamber 43 to the air outlet channel 111. The lower end of the air outlet channel 111 can be tightly fitted into the through-hole 4230 to ensure airtightness. Of course, in other embodiments, the lower end of the air outlet channel 111 can also be tightly fitted onto the extension 423.

[0076] In some embodiments, the base 41 may include a seat body 413 and a support portion 414 extending upward from the upper end surface of the seat body 413. An air inlet 4130 is formed through the seat body 413, and the air inlet 4130 communicates with the air inlet 120 and the atomizing chamber 43, respectively. The outer wall surface of the seat body 413 can be sealed with the inner wall surface of the outer casing 10, which helps to improve the sealing effect on the liquid storage chamber 110. The seat body 413 and the outer casing 10 can be tightly connected by interference fit or snap-fit ​​connection.

[0077] The support portion 414 supports the atomizing core 30. The support portion 414 is a cylindrical shape with an open top, and it is fitted onto the main body portion 422 to form the atomizing chamber 43. Specifically, in this embodiment, the main body portion 422 is tightly fitted onto the support portion 414. The support portion 414 and the main body portion 422 can be tightly connected by interference fit or snap-fit ​​connection.

[0078] The first pressing surface 411 and the supporting part 412 are formed at the upper end of the supporting part 414, so that the two side walls of the upper end of the supporting part 414 along the length direction X form a stepped structure.

[0079] In some embodiments, the mounting base assembly 40 further includes a ventilation channel 415, which connects the liquid storage chamber 110 to the outside atmosphere to balance the pressure inside the liquid storage chamber 110 and solve the problem of unstable liquid discharge due to excessive negative pressure inside the liquid storage chamber 110.

[0080] The ventilation channel 415 may be formed on the base 41, on the top seat 42, or partially on the base 41 and partially on the top seat 42. In this embodiment, the ventilation channel 415 is formed on the base 41. Specifically, the ventilation channel 415 may include a ventilation groove 4150 formed by the recess of the outer side of the support portion 414. When the main body portion 422 is sleeved on the support portion 414, the inner wall surface of the main body portion 422 covers the opening of the ventilation groove 4150 to form the ventilation channel 415.

[0081] The ventilation channel 4150 can be a capillary channel, which can store a certain amount of leaked liquid through capillary force. Of course, in other embodiments, the ventilation channel 4150 can be a non-capillary channel.

[0082] The ventilation channel 415 has an inlet 4151 that communicates with the outside and an outlet 4152 that communicates with the liquid storage chamber 110. The inlet 4151 can communicate with the atomizing chamber 43 and is disposed through the side wall of the support part 414.

[0083] The lower end of the ventilation groove 4150 is connected to the air inlet 4151, and the upper end is connected to the air outlet 4152. The ventilation groove 4150 can extend in a non-linear shape (e.g., S-shaped) between the air inlet 4151 and the air outlet 4152, which helps to increase the liquid storage space of the ventilation groove 4150. Of course, in other embodiments, the ventilation groove 4150 can also extend in a linear shape.

[0084] The number of ventilation channels 415 is not limited, and there can be one or more. In this embodiment, there are two ventilation channels 415, which are located on both sides of the support portion 414 along the length direction.

[0085] Figures 8 to 9 The atomizing component 20 of the second embodiment of the present invention is shown. Its main difference from the first embodiment is that the outer wall surface of the support member 33 in this embodiment has a plurality of liquid guiding grooves 332 recessed therein. Each liquid guiding groove 332 penetrates both axial end faces of the support member 33, thereby ensuring that both ends of each liquid guiding groove 332 are in fluid communication with the liquid storage chamber 110. The liquid guiding member 31, after being sleeved on the support member 33, is in fluid communication with the plurality of liquid guiding grooves 332.

[0086] Specifically, the support member 33 may be in the shape of a solid rod (e.g., a round rod), meaning that no liquid guiding channel 330 is formed axially through the support member 33. Multiple liquid guiding grooves 332 are disposed on the outer wall surface of the support member 33, with each groove 332 having two ends in fluid communication with two liquid discharge channels 44, and subsequently with the liquid storage chamber 110. The multiple liquid guiding grooves 332 can be evenly spaced circumferentially on the support member 33, which facilitates the uniform guidance of the aerosol generation matrix to the liquid guiding member 31.

[0087] Compared with the support member 33 in the first embodiment that uses a single liquid channel (liquid channel 330) for liquid supply, this embodiment adopts a multi-channel liquid supply structure with multiple liquid channels 332. This avoids the problem of discontinuous liquid supply caused by gas entering the single liquid channel during use, so that the liquid supply from the support member 33 to the liquid supply member 31 has good continuity and redundancy in the risk of liquid supply blockage, ensuring continuous and stable liquid supply throughout the process, and guaranteeing the taste and lifespan of the atomizing core 30.

[0088] Each liquid guiding groove 332 extends from one end of the support member 33 in a straight line or non-linear manner to the other end of the support member 33. In some embodiments, each liquid guiding groove 332 can extend linearly along the axial direction of the support member 33, which is beneficial for processing and results in a shorter liquid guiding path. In some embodiments, the axial length of the support member 33 can be 5mm to 12mm. Of course, in other embodiments, the liquid guiding groove 332 can also extend linearly at a certain angle to the axial direction of the support member 33, or the liquid guiding groove 332 can also extend non-linearly.

[0089] The cross-sectional shape of the liquid guiding groove 332 is not limited; for example, it can be rectangular, trapezoidal, triangular, semi-circular, semi-elliptical, or other shapes. The maximum dimension (e.g., depth or width) of the liquid guiding groove 332 is smaller than the radius of the support member 33. The minimum dimension of the liquid guiding groove 332 must ensure that its liquid supply capacity is greater than the effective liquid supply diameter of the liquid guiding member 31 (typically not exceeding 0.2 mm). For example, in some embodiments, the outer diameter of the support member 33 is 1 mm to 6 mm, the depth of the liquid guiding groove 332 is 0.2 mm to 3 mm, and the width of the liquid guiding groove 332 can be 0.2 mm to 3 mm.

[0090] As described herein, the depth dimension of the liquid guiding groove 332 refers to the depth of the liquid guiding groove 332 recessed inward from the outer side of the support member 33, that is, the dimension of the liquid guiding groove 332 along the radial direction of the support member 33. The width dimension of the liquid guiding groove 332 refers to the dimension of the liquid guiding groove 332 along the circumferential direction of the support member 33.

[0091] In some embodiments, the liquid guiding channel 332 can be a capillary channel with capillary force, which can guide liquid through capillary force, thereby improving the liquid guiding effect. Furthermore, the capillary force of the liquid guiding channel 332 can be less than or equal to the capillary force of the liquid guiding component 31, allowing the aerosol generating matrix to be guided more quickly from the liquid guiding channel 332 with lower capillary force to the liquid guiding component 31 with higher capillary force, thus increasing the liquid guiding speed.

[0092] Of course, in other embodiments, the capillary force of the liquid guiding groove 332 can also be greater than the capillary force of the liquid guiding component 31, or the liquid guiding groove 332 can also be a non-capillary groove without capillary force, all of which can achieve the liquid guiding effect.

[0093] Of course, the total cross-sectional area of ​​the multiple liquid guiding channels 332 should not be too small, so as to ensure that the liquid guiding channels 332 have sufficient liquid supply capacity and can supply the liquid guiding component 31 with sufficient aerosol generation matrix.

[0094] In some embodiments, the number of liquid guiding channels 332 can be 3 to 12, and the cross-sectional area of ​​a single liquid guiding channel 332 can be 0.04 mm. 2 ~2.5mm 2 This can achieve a better fluid conduction effect.

[0095] The support member 33 can be made of a rigid, non-porous material or a rigid, porous material. Materials that can be used for the support member 33 include, but are not limited to, metals, ceramics, glass, and engineering plastics.

[0096] In some embodiments, the diameter of the yarn used in the liquid guiding member 31 is smaller than the depth and width of the liquid guiding groove 332, thereby reducing the risk of the liquid guiding member 31 blocking the liquid guiding groove 332 when it is tightly wrapped around the support member 33.

[0097] In addition, the depth of the liquid guiding groove 332 can be greater than the radius of the atomizing core 30 after it is pressed by the first pressing surface 411 and the second pressing surface 421. In this way, the liquid guiding component 31 will not completely block the liquid guiding groove 332 when it is squeezed into the liquid guiding groove 332.

[0098] When the fixing assembly 40 includes two abutment portions 412, the length of the liquid guiding member 31 can be greater than the length of the support member 33. The length of the support member 33 is less than the distance between the two abutment portions 412, so that there is a gap between the two end faces of the support member 33 and the two abutment portions 412 respectively. In this way, the abutment portions 412 can be prevented from blocking the liquid guiding groove 332.

[0099] Of course, in other embodiments, the fixing seat assembly 40 may not be provided with the abutment part 412, so that there is no risk that the abutment part 412 will block the liquid guide groove 332.

[0100] It should be noted that the electronic atomizing device 1 in this invention can be either entirely non-removable or partially removable.

[0101] exist Figures 1 to 3 In the illustrated embodiment, the electronic atomizing device 1 is a non-removable whole. The outer casing 10 may include a first casing 11 and a second casing 12 disposed at the lower end of the first casing 11. The first casing 11 is a cylindrical shape with an open lower end, and is divided into two spaces by a partition wall 113. One of these spaces forms a liquid storage chamber 110 and an air outlet channel 111, while the other accommodates the battery 50.

[0102] The second housing 12 can be sleeved together with the first housing 11. Specifically, the second housing 12 can be sleeved on the lower end of the first housing 11. The second housing 12 and the first housing 11 can be tightly connected by a non-removable snap fastener. Of course, in other embodiments, the second housing 12 and the first housing 11 can also be tightly connected by other means such as interference fit.

[0103] In some embodiments, a mounting base 13 may also be provided inside the housing 10, on which the atomizing core 30 and the battery 50 can be supported and abutted. The airflow sensor 60 is mounted on the mounting base 13. Specifically, the airflow sensor 60 can be embedded in the mounting base 13 through the bottom opening of the mounting base 13.

[0104] The mounting base 13 can be made of silicone material, and it can be embedded in the second housing 12 and seal against the inner wall of the second housing 12. Of course, in other embodiments, the mounting base 13 can also be made of other materials such as plastic, and a seal can be achieved by additionally providing a sealing element between the mounting base 13 and the second housing 12.

[0105] exist Figures 10 to 11 In the illustrated embodiment, the electronic atomizing device 1 includes an atomizer 100 and a power supply device 200 connected to the atomizer 100. The atomizer 100 is primarily used to store the aerosol generation matrix and atomize it after being powered on. Accordingly, the atomizer 100 includes a liquid storage chamber 110 and an atomization assembly 20. The power supply device 200 is electrically connected to the atomizer 100 and is mainly used to supply power to the atomizer 100 and control the opening and closing of the entire electronic atomizing device 1. Accordingly, the power supply device 200 includes a battery 50, a control circuit, and an airflow sensor 60.

[0106] The atomizer 100 and the power supply unit 200 can be detachably connected via threaded connection, magnetic connection, or detachable clips, allowing for continued use by replacing either the atomizer 100 or the power supply unit 200 individually, thus reducing operating costs. Alternatively, the atomizer 100 and the power supply unit 200 can be non-detachably connected, reducing user operation.

[0107] Furthermore, the atomizer 100 includes a liquid storage housing 10a, within which a liquid storage chamber 110 and an air outlet channel 111 are formed, and an air inlet 112 is formed at the upper end of the liquid storage housing 10a. The atomizing component 20 is disposed within the liquid storage housing 10a, and the atomizing core 30 is in fluid communication with the liquid storage chamber 110 and the air outlet channel 111, respectively.

[0108] The power supply unit 200 includes a power supply housing 10b, and a battery 50, a control circuit, and an airflow sensor 60 are all disposed within the power supply housing 10b. A receiving cavity 121 may be formed at the upper end of the power supply housing 10b, and the atomizer 100 is at least partially housed within the receiving cavity 121. The liquid storage housing 10a and the power supply housing 10b cooperate to form the outer shell 10 of the electronic atomizing device 1.

[0109] The above embodiments only illustrate preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can freely combine the above technical features without departing from the concept of the present invention, and can also make several modifications and improvements, all of which fall within the protection scope of the present invention.
