Abstract
Description
Technical Field
[0001] This application relates to the field of electronic cigarette technology, and more specifically, to an atomizing core assembly, an electronic cigarette atomizing device, and an electronic cigarette. Background Technology
[0002] Ceramic heating elements are widely used in electronic cigarettes. A typical ceramic heating element consists of a porous ceramic body that conducts liquid and a heating element disposed on the porous ceramic body. The porous ceramic body includes an atomizing surface and a liquid-absorbing surface arranged opposite each other, with the heating element disposed on the atomizing surface.
[0003] Currently, eccentric holes are created in porous ceramic bodies to connect the atomizing and liquid-absorbing surfaces. When used in e-cigarettes, these eccentrically shaped porous ceramic bodies eliminate the need for additional upper and lower supports, allowing vapor from the atomizing chamber to directly enter the exhaust channel through the eccentric holes. However, because the through-holes connecting the atomizing and liquid-absorbing surfaces are eccentric, the exhaust channel on the e-cigarette casing also needs to be tilted at a predetermined angle to align with the eccentric holes. Therefore, creating eccentric holes in porous ceramic bodies results in an inclined exhaust channel, which is inconvenient for the design of the e-cigarette casing. Summary of the Invention

[0059] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.
[0060] According to a first aspect of this application, an atomizing core assembly is provided. (Refer to...) Figures 1-7 As shown: The atomizer core assembly includes:
[0061] A porous body 1 and a heating element 10 disposed on the porous body 1; the porous body 1 includes a liquid absorption surface 12 and an atomizing surface 11; the heating element 10 is disposed on the atomizing surface 11;
[0062] The porous body 1 has a smoke channel 13, one end of which penetrates the atomizing surface 11 and forms a first opening 111 on the atomizing surface 11, and the other end of which penetrates the liquid-absorbing surface 12 and forms a second opening 121 on the liquid-absorbing surface.
[0063] Along the direction from the liquid absorption surface 12 to the atomizing surface 11, the porous body 1 has a first central axis L, the first opening 111 has a second central axis, and the second central axis is offset to one side of the porous body 1 by a predetermined distance relative to the first central axis L.
[0064] In this embodiment, a first opening 111 is formed on the atomizing surface 11, and a second opening 121 is formed on the liquid-absorbing surface 12. The first opening 111 and the second opening 121 are connected through a smoke channel 13. That is, the first opening 111, the second opening 121, and the smoke channel 13 constitute a through-hole structure. The through-hole structure penetrates the atomizing surface 11 and the liquid-absorbing surface 12 of the porous body 1. When the atomizing core assembly in this embodiment is applied to an electronic cigarette, the liquid-absorbing surface 12 of the porous body 1 forms a sealed fit with the shell of the electronic cigarette. The atomizing surface 11 of the porous body 1 cooperates with the lower base of the electronic cigarette to form an atomizing chamber.
[0065] In the atomizing core assembly of this application embodiment, the first central axis L of the porous body 1 does not coincide with the second central axis of the first opening 111. The second central axis is offset by a certain predetermined distance relative to the first central axis L. That is, the first opening on the atomizing surface 11 is an eccentric opening. When this atomizing core assembly is applied to an electronic cigarette, when outside air enters the atomizing chamber of the electronic cigarette from the lower base and mixes with the smoke generated on the atomizing surface 11, the airflow will bypass the first opening 111 and then enter the air outlet channel of the electronic cigarette. Therefore, the eccentrically set first opening can help improve the airflow path in the electronic cigarette and increase the uniformity of the mixing between the outside air entering the electronic cigarette and the smoke generated inside the electronic cigarette.
[0066] More specifically, the first opening 111 is arranged at a distance from the heating element 10.
[0067] Therefore, in this embodiment, only the first opening 111 on the atomizing surface 11 is limited to being an eccentric opening, which can help improve the airflow path in the electronic cigarette and increase the uniformity of the mixing between the air entering the electronic cigarette from the outside and the smoke generated inside the electronic cigarette; the second opening 121 on the liquid absorption surface 12 is not an eccentric opening. When the liquid absorption surface 12 is sealed with the electronic cigarette shell, the air outlet channel of the electronic cigarette and the second opening 121 are not eccentric openings. Therefore, the air outlet channel of the electronic cigarette does not need to be set as an inclined channel (i.e., the channel of the electronic cigarette does not need to be offset), which simplifies the design process of the air outlet channel on the electronic cigarette shell.
[0068] In one embodiment, refer to Figures 1-7 As shown, along the direction from the liquid absorption surface 12 to the atomizing surface 11, the second opening 121 has a third central axis, which is coaxially arranged with the first central axis.
[0069] Specifically, in this embodiment, the first central axis of the porous body 1 coincides with the third central axis of the second opening 121. That is, the second opening 121 is positively positioned on the liquid-absorbing surface 12, and the liquid-absorbing surface 12 is sealed to the e-cigarette shell, forming an air outlet channel and a liquid storage chamber inside the shell. Since the second opening 121 is positively positioned on the liquid-absorbing surface 12, the central axis of the air outlet channel of the shell is vertical, and the air outlet channel does not need to be tilted, which facilitates the molding of the e-cigarette shell and the fitting of the e-cigarette shell with the atomizing core assembly.
[0070] In one embodiment, refer to Figure 6 As shown, along the direction of the second central axis offset relative to the first central axis, on both sides of the first opening 111, the atomizing surface 11 has a first side area and a second side area, the area of the first side area is larger than the area of the second side area, and the heating element 10 is disposed in the first side area.
[0071] Specifically, taking the porous body 1 as an elliptical cylinder and the first opening 111 as an elliptical hole as an example, with the major axis of the ellipse of the first opening 111 as the reference, the area below the major axis of the ellipse of the first opening 111 is the first side area, and the area above the major axis of the ellipse of the first opening 111 is the second side area.
[0072] In this specific example, refer to Figure 1Taking the porous body 1 as an elliptical cylinder and the first opening 111 as an elliptical hole as an example, the first opening 111 is offset to one side along the minor axis of the ellipse on the porous body 1, while the heating element 10 is offset to the other side along the minor axis of the ellipse on the atomizing surface 11. That is, the heating element 10 is arranged on one side relative to the first opening 111, which can improve the heating efficiency of the heating element 10, make the heating of the atomizing surface 11 stable and efficient, and improve the atomization effect of the atomizing surface 11; and can maximize the width of the hole edge on the side of the porous body 1 with the heating element 10, thereby improving the strength of the atomizing core.
[0073] In one embodiment, the porous body 1 has an elongated cross-section perpendicular to the first central axis, the width direction of the elongated structure is a first direction, and the second central axis of the first opening 111 is offset toward the edge of the porous body along the first direction.
[0074] Furthermore, the first side region and the second side region are distributed on both sides of the first opening along the first direction.
[0075] Specifically, the cross-section of the porous body along the direction perpendicular to the first central axis is an elongated structure. For example, the elongated structure can be a rectangular structure or an elliptical structure. The width direction of the elongated structure is the first direction. For example, if the elongated structure is rectangular, the width direction of the rectangular structure is the direction of the extension of the shorter side; if the elongated structure is elliptical, the width direction of the elliptical structure is the direction of the extension of the shorter axis.
[0076] The second central axis of the first opening 111 is offset along the first direction toward the edge of the porous body 1 to form a first side region and a second side region. For example, without affecting the temperature distribution of the porous body's atomization surface, and without affecting the edge temperature of the porous body, the second central axis of the first opening can be offset toward the edge of the porous body 1 as much as possible.
[0077] Preferably, the maximum dimension of the porous body 1 along the first direction is W, and the predetermined distance / W = 1 / 5-1 / 3.
[0078] Specifically, if the offset distance of the first opening 111 relative to the porous body 1 is too large, it will easily result in the width of the side next to the first opening 111 being too small, thus reducing the strength of the porous body 1 on that side and affecting the overall strength quality of the porous body 1. If the offset distance of the first opening 111 relative to the porous body 1 is too small, it will not effectively improve the airflow path and may also affect the atomization effect of the atomizing surface. Therefore, in this embodiment, the predetermined offset distance of the first opening 111 is set to 1 / 5 to 1 / 3 of the maximum size W, which ensures improved airflow without affecting the strength of the porous body.
[0079] In one embodiment, refer to Figures 1-5As shown, along the direction from the liquid absorption surface 12 to the atomizing surface 11, the smoke channel 13 sequentially includes a first channel 131, a second channel 132 communicating with the first channel 131, and a third channel 133 communicating with the second channel 132;
[0080] Along the direction from the liquid absorption surface 12 to the atomizing surface 11, the central axis of the first channel 131 is coaxial with the first central axis, the central axis of the second channel 132 is coaxial with the first central axis, and there is an angle between the central axis of the third channel 133 and the first central axis.
[0081] Specifically, along the direction from the liquid absorption surface 12 to the atomizing surface 11, the first channel 131, the second channel 132, and the third channel 133 are interconnected. One port of the first channel 131 is formed on the liquid absorption surface 12, that is, one port of the first channel 131 is the second opening 121. One port of the third channel 133 is formed on the atomizing surface 11, that is, one port of the third channel 133 is the first opening 111. The aerosol generated by the atomization of e-liquid passes sequentially through the third channel 133, the second channel 132, and the first channel 131 to the air outlet channel and is inhaled by the user.
[0082] Along the direction from the liquid absorption surface 12 to the atomizing surface 11, the central axis of the first channel 131 is coaxial with the first central axis, that is, the first channel 131 is a vertical channel. In other words, the projections of the two ports of the first channel 131 in the direction from the liquid absorption surface 12 to the atomizing surface 11 overlap.
[0083] The central axis of the second channel 132 is coaxial with the first central axis. Therefore, the second channel 132 is a vertical channel, that is, the projections of the two ports of the second channel 132 in the direction from the liquid absorption surface 12 to the atomizing surface 11 overlap.
[0084] There is an angle between the central axis of the third channel 133 and the first central axis. Therefore, the third channel 133 is an inclined channel, that is, the central axis of the third channel 133 is an axis inclined in a certain direction. In other words, the projections of the two ports of the third channel 133 along the direction from the liquid absorption surface to the atomizing surface 11 do not overlap.
[0085] In this embodiment, the central axis of the first channel 131 is coaxial with the first central axis. When the atomizing core assembly is applied to an electronic cigarette, the air outlet channel on the electronic cigarette shell cooperates with the first channel 131, that is, the central axis of the air outlet channel is coaxial with the first central axis, thus avoiding the offset setting of the air outlet channel.
[0086] In one embodiment, refer to Figures 1-5 As shown, along the direction from the liquid absorption surface 12 to the atomizing surface 11, the smoke channel 13 sequentially includes a first channel 131, a second channel 132 communicating with the first channel 131, and a third channel 133 communicating with the second channel 132;
[0087] Along the direction from the liquid absorption surface 12 to the atomizing surface 11, the central axis of the first channel 131 is coaxial with the first central axis, the central axis of the second channel 132 forms an angle with the first central axis, and the central axis of the third channel 133 forms an angle with the first central axis.
[0088] Specifically, along the direction from the liquid absorption surface 12 to the atomizing surface 11, the first channel 131, the second channel 132, and the third channel 133 are interconnected. One port of the first channel 131 is formed on the liquid absorption surface 12, that is, one port of the first channel 131 is the second opening 121. One port of the third channel 133 is formed on the atomizing surface 11, that is, one port of the third channel 133 is the first opening 111. The aerosol generated by the atomization of e-liquid passes sequentially through the third channel 133, the second channel 132, and the first channel 131 to the air outlet channel and is inhaled by the user.
[0089] Along the direction from the liquid absorption surface 12 to the atomizing surface 11, the central axis of the first channel 131 is coaxial with the first central axis, that is, the first channel 131 is a vertical channel. In other words, the projections of the two ports of the first channel 131 in the direction from the liquid absorption surface 12 to the atomizing surface 11 overlap.
[0090] There is an angle between the central axis of the second channel 132 and the first central axis. Therefore, the second channel 132 is an inclined channel, that is, the central axis of the second channel 132 is an axis inclined in a certain direction. In other words, the projections of the two ports of the second channel 132 along the direction from the liquid absorption surface 12 to the atomizing surface 11 do not overlap.
[0091] There is an angle between the central axis of the third channel 133 and the first central axis. Therefore, the third channel 133 is an inclined channel, that is, the central axis of the third channel 133 is an axis inclined in a certain direction. In other words, the projections of the two ports of the third channel 133 along the direction from the liquid absorption surface 12 to the atomizing surface 11 do not overlap.
[0092] In this embodiment, the central axis of the first channel 131 is coaxial with the first central axis. When the atomizing core assembly is applied to an electronic cigarette, the air outlet channel on the electronic cigarette shell cooperates with the first channel 131, that is, the central axis of the air outlet channel is coaxial with the first central axis, thus avoiding the offset setting of the air outlet channel.
[0093] In one embodiment, refer to Figures 1-5 As shown, along the direction from the atomizing surface 11 to the liquid absorption surface 12, the inner diameter of the second channel 132 gradually increases, and the inner diameter of the third channel 133 gradually changes.
[0094] Specifically, in order for the aerosol formed after atomization to pass smoothly through the smoke channel, the inner diameter of the second channel 132 is gradually increased, increasing the amount of smoke entering the channel and improving the user experience.
[0095] In addition, the porous body 1 is generally formed by injection molding. Without considering the ease of demolding, the inner diameter of the second channel 132 gradually increases, while the inner diameter of the third channel 133 can gradually decrease or increase; or the inner diameter of the third channel 133 can remain unchanged.
[0096] In one embodiment, refer to Figure 1 As shown, along the direction from the atomizing surface 11 to the liquid absorption surface 12, the inner diameter of the second channel 132 gradually increases, while the inner diameter of the third channel 133 gradually decreases. Figure 1 The porous body shown is difficult to demold.
[0097] In one embodiment, refer to Figure 2 and Figure 5 As shown, along the direction from the atomizing surface 11 to the liquid absorption surface 12, the inner diameter of the second channel 132 gradually increases, while the inner diameter of the third channel 133 gradually decreases. Figure 2 and Figure 5 The porous body shown is easy to demold.
[0098] In one embodiment, refer to Figures 1-5 As shown, along the direction perpendicular to the direction from the liquid absorption surface 12 to the atomizing surface 11, the inner diameter of the first channel 131 is a first dimension, and the maximum inner diameter of the second channel 132 is a second dimension, wherein the first dimension is larger than the second dimension.
[0099] Specifically, when the atomizing core assembly is applied to an electronic cigarette, the air outlet channel on the electronic cigarette casing needs to mate with the inner wall of the first channel 131, that is, the air outlet channel needs to be embedded in the first channel. Even with the air outlet channel embedded in the first channel, it still needs to communicate with the second channel 132 and the third channel 133. Therefore, in order to allow more of the atomized aerosol to flow into the air outlet channel, the first dimension of the first channel needs to be larger than the second dimension of the second channel.
[0100] In one embodiment, refer to Figure 1 As shown, the second channel 132 has a first sidewall 1321 and a second sidewall 1322, and the third channel 133 has a third sidewall 1331 and a fourth sidewall 1332;
[0101] Both the first sidewall 1321 and the third sidewall 1331 are inclined toward the direction of the first central axis;
[0102] Both the second sidewall 1322 and the fourth sidewall 1332 are inclined away from the first central axis.
[0103] Furthermore, the first sidewall 1321 and the third sidewall 1331 are coplanar, and the inclination angle of the second sidewall 1322 is greater than the inclination angle of the fourth sidewall 1332.
[0104] The second channel 132 has a first sidewall 1321 and a second sidewall 1322 in a direction perpendicular to the direction from the atomizing surface 11 to the liquid absorption surface 12. The third channel 133 has a third sidewall 1331 and a fourth sidewall 1332.
[0105] The first sidewall 1321 and the second sidewall 1322 are both inclined toward the direction of the first central axis, that is, the left sidewalls of the second channel 132 and the third channel 133 gradually incline toward the direction of the first central axis.
[0106] The second sidewall 1322 and the fourth sidewall 1332 are both inclined away from the first central axis, that is, the right sidewalls of the second channel 132 and the third channel 133 gradually incline away from the first central axis.
[0107] At this point, in the direction from the atomizing surface 11 to the liquid-absorbing surface 12 of the porous body, the maximum distance from the left side wall of the second channel to the first central axis is smaller than the minimum distance from the left side wall of the third channel to the first central axis. (Refer to...) Figure 1 As shown, when forming the porous body 1, the parting surface of the mold needs to be inclined, and demolding can only be achieved in the inclined direction. If the mold is demolded up and down along the first central axis, one of the molds cannot be demolded due to interference. For example, the size of the first mold gradually increases in the direction from the atomizing surface 11 to the liquid absorption surface 12 to facilitate demolding of the first mold. At the same time, the size of the second mold gradually decreases in the direction from the atomizing surface 11 to the liquid absorption surface 12 to facilitate demolding of the second mold. If the mold is demolded up and down along the axis of the porous body, one of the molds (the first mold) cannot be demolded due to interference.
[0108] In one embodiment, refer to Figure 2 , Figure 3 and Figure 5 As shown, the second channel 132 has a first sidewall 1321 and a second sidewall 1322, and the third channel 133 has a third sidewall 1331 and a fourth sidewall 1332;
[0109] Both the first sidewall 1321 and the second sidewall 1322 are inclined surfaces that are inclined away from the first central axis;
[0110] Both the third sidewall 1331 and the fourth sidewall 1332 are inclined surfaces that are tilted away from the first central axis.
[0111] Specifically, in a direction perpendicular to the direction from the atomizing surface 11 to the liquid-absorbing surface 12, the second channel 132 has a first sidewall 1321 and a second sidewall 1322. The third channel 133 has a third sidewall 1331 and a fourth sidewall 1332.
[0112] Both the first sidewall 1321 and the second sidewall 1331 are inclined away from the first central axis, that is, the left sidewalls of the second channel 132 and the third channel 133 gradually incline away from the first central axis.
[0113] The second sidewall 1322 and the fourth sidewall 1332 are both inclined away from the first central axis, that is, the right sidewalls of the second channel 132 and the third channel 133 gradually incline away from the first central axis.
[0114] At this point, in the direction from the atomizing surface 11 to the liquid-absorbing surface 12 of the porous body 1, the inner diameter of the third channel 133 to the second channel 132 gradually increases. That is, the maximum inner diameter in the third channel 133 is the same as the minimum inner diameter in the second channel 132. This smoke channel 13 design facilitates the molding of the porous body 1 of the atomizing core assembly. For example, the mold for molding the porous body 1 includes a first mold and a second mold, which together form a cavity, and the structure of the cavity matches the structure of the porous body 1. The smoke channel arrangement in this embodiment allows the first mold and the second mold to be demolded along a horizontal plane perpendicular to the axis of the porous body 1, facilitating the demolding of the porous body. The first mold and the second mold open vertically along the first central axis, avoiding wear on the parting surface during the demolding of the porous body.
[0115] In one embodiment, see reference Figure 2 and Figure 3 As shown, the tilt angle of the first sidewall 1321 is greater than the tilt angle of the third sidewall 1331, and the tilt angle of the second sidewall 1322 is greater than the tilt angle of the fourth sidewall 1332.
[0116] For example, refer to Figure 2 As shown, the third sidewall 1331 in the third channel 133 is an inclined surface that slopes away from the first central axis. The fourth sidewall 1332 in the third channel 133 is also an inclined surface that slopes away from the first central axis.
[0117] The first sidewall 1321 in the second channel 132 is an inclined surface that slopes away from the first central axis. The second sidewall 1322 in the second channel 132 is an inclined surface that slopes away from the first central axis. The first sidewall 1321 and the third sidewall 1331 are coplanar.
[0118] In other words, the inner diameter of the junction of the third channel 133 and the second channel 132 changes abruptly.
[0119] In this embodiment, both the third channel 133 and the second channel 132 are composed of trapezoidal holes.
[0120] In the trapezoidal hole corresponding to the third channel 133, the upper base dimension of the trapezoidal hole is larger than the lower base dimension. In the trapezoidal hole corresponding to the second channel 132, the upper base dimension of the trapezoidal hole is larger than the lower base dimension.
[0121] In this embodiment, the design of the smoke channel 13 of the porous body 1 ensures that when the mold of the porous body 1 is demolded along the direction from the atomizing surface 11 to the liquid absorption surface 12, the mold will not interfere with the structure of the porous body 1, thus simplifying the demolding process.
[0122] For example, refer to Figure 3 As shown, the third sidewall 1331 in the third channel 133 is a vertical surface. The fourth sidewall 1332 in the third channel 133 is a vertical surface.
[0123] The first sidewall 1321 in the second channel 132 is an inclined surface that slopes away from the first central axis. The second sidewall 1322 in the second channel 132 is an inclined surface that slopes away from the first central axis.
[0124] In this embodiment, a "vertical surface" is defined as follows: in the direction from the atomizing surface 11 to the liquid-absorbing surface 12, the vertical surface has at least one vertical line parallel to the first central axis. The vertical surface can be a vertical plane or a vertical arc surface. An "inclined surface" is defined as follows: in the direction from the atomizing surface 11 to the liquid-absorbing surface 12, the inclined surface does not have a vertical line parallel to the first central axis. The inclined surface can be an inclined plane or an inclined arc surface.
[0125] In other words, the inner diameter of the junction of the third channel 133 and the second channel 132 changes abruptly.
[0126] In this embodiment, the third channel 133 is a circular or square hole, and the second channel 132 is a trapezoidal hole. The inner diameter of the circular hole in the third channel 133 is the same as the bottom dimension of the trapezoidal hole in the second channel 132.
[0127] In this embodiment, the design of the smoke channel 13 of the porous body 1 ensures that when the mold of the porous body 1 is demolded along the direction from the atomizing surface 11 to the liquid absorption surface 12, the mold will not interfere with the structure of the porous body 1, thus simplifying the demolding process.
[0128] In one embodiment, refer to Figure 4 As shown, the first sidewall 1321 and the third sidewall 1331 are coplanar, and the inclination angle of the second sidewall 1322 is greater than the inclination angle of the fourth sidewall 1332.
[0129] Reference Figure 4As shown, the third sidewall 1331 in the third channel 133 is a vertical surface. The fourth sidewall 1332 in the third channel 133 is an inclined surface.
[0130] The first sidewall 1321 in the second channel 132 is a vertical surface. The second sidewall 1322 in the second channel 132 is an inclined surface that slopes away from the first central axis.
[0131] The first sidewall 1321 and the third sidewall 1331 are coplanar, and the inclination angle of the second sidewall 1322 is greater than that of the fourth sidewall 1332.
[0132] In other words, the inner diameter of the junction of the third channel 133 and the second channel 132 changes abruptly.
[0133] In this embodiment, both the third channel 133 and the second channel 132 are right-angled trapezoidal holes.
[0134] In the right-angled trapezoidal hole corresponding to the third channel 133, the upper base dimension of the trapezoidal hole is larger than the lower base dimension. In the right-angled trapezoidal hole corresponding to the second channel 132, the upper base dimension of the trapezoidal hole is larger than the lower base dimension.
[0135] In this embodiment, the design of the smoke channel 13 of the porous body 1 ensures that when the mold of the porous body 1 is demolded along the direction from the atomizing surface 11 to the liquid absorption surface 12, the mold will not interfere with the structure of the porous body 1, thus simplifying the demolding process.
[0136] In one embodiment, refer to Figure 5 As shown, the first sidewall 1321 and the third sidewall 1331 are coplanar, and the second sidewall 1322 and the fourth sidewall 1332 are coplanar.
[0137] Reference Figure 5 As shown, the third sidewall 1331 in the third channel 133 is an inclined surface that slopes away from the first central axis. The fourth sidewall 1332 in the third channel 133 is also an inclined surface that slopes away from the first central axis.
[0138] The first sidewall 1321 in the second channel 132 is an inclined surface that slopes away from the first central axis. The second sidewall 1322 in the second channel 132 is an inclined surface that slopes away from the first central axis.
[0139] The first sidewall 1321 and the third sidewall 1331 are coplanar, meaning their inclination angles are the same. Similarly, the second sidewall 1322 and the fourth sidewall 1332 are coplanar, meaning their inclination angles are the same. In other words, the inner diameter at the connection between the third channel 133 and the second channel 132 does not change abruptly. In this embodiment, both the third channel 133 and the second channel 132 are trapezoidal holes.
[0140] In the trapezoidal hole corresponding to the third channel 133, the upper base dimension of the trapezoidal hole is larger than the lower base dimension. In the trapezoidal hole corresponding to the second channel 132, the upper base dimension of the trapezoidal hole is larger than the lower base dimension. The upper base dimension of the trapezoidal hole corresponding to the third channel 133 is the same as the lower base dimension of the trapezoidal hole corresponding to the second channel 132.
[0141] In this embodiment, the design of the smoke channel 13 of the porous body 1 ensures that when the mold of the porous body 1 is demolded along the direction from the atomizing surface 11 to the liquid absorption surface 12, the mold will not interfere with the structure of the porous body 1, thus simplifying the demolding process.
[0142] In one embodiment, refer to Figures 1-5 As shown, the atomizing core assembly also includes an atomizing core seal 14, which is sleeved on the porous body 1 to form a seal;
[0143] A tubular structure 141 is formed on the atomizing core seal 14, and the tubular structure 141 is embedded in the first channel 131.
[0144] In this embodiment, the porous body 1, the atomizing core seal 14, and the e-cigarette housing together form the liquid storage chamber; the porous body 1, the e-cigarette housing, and the lower base of the e-cigarette together form the atomizing chamber. The atomizing core seal 14 can improve the sealing performance between the atomizing core assembly and the inner wall of the e-cigarette housing, prevent unnecessary conduction, and effectively avoid oil leakage.
[0145] In this embodiment, the tubular structure 141 on the atomizing core seal 14 is inserted into the first channel 131 to seal the periphery of the first channel 131 to prevent e-liquid in the e-cigarette reservoir from leaking out. The tubular structure improves the sealing effect of the atomizing core seal 14.
[0146] Specifically, when the atomizing core assembly in this embodiment is applied to an electronic cigarette, the e-liquid permeates from the absorbent surface 12 to the atomizing surface 11 through the porous body 1 of the atomizing core, and is heated by the heating element 10 on the atomizing surface 11 to generate smoke. The smoke enters the smoke channel 13 through the first opening 111, and then enters the tubular structure 141 through the second opening 121, and then enters the air outlet channel of the electronic cigarette to be inhaled by the user.
[0147] In this embodiment, when the air outlet channel of the electronic cigarette is used in conjunction with the atomizing core assembly, the air outlet channel does not need to be set as an offset setting, which facilitates the molding of the electronic cigarette shell and the assembly of the electronic cigarette shell and the atomizing core assembly.
[0148] In one embodiment, refer to Figure 3 As shown, the porous body 1 has a chamfered structure on the side near the heating element 10.
[0149] For example, the porous body 1 includes a first side surface and a second side surface. The first side surface is connected to the atomizing surface 11, and the second side surface is connected to the atomizing surface 11. The first side surface and the second side surface are arranged opposite to each other.
[0150] A chamfered structure is formed at the junction of the first side surface and the atomizing surface 11. A chamfered structure is also formed at the junction of the second side surface and the atomizing surface 11. Forming chamfered structures on the porous body 1 facilitates assembly between the porous body 1 and the lower base, and enhances the overall structural strength of the porous body 1. In an optional embodiment, the chamfered structure can be a right-angled structure or a rounded corner structure.
[0151] According to a second aspect of this application, an electronic cigarette atomizing device is provided. (See also...) Figure 7 As shown, the electronic cigarette atomizing device includes:
[0152] The housing 2, the liquid storage chamber 21 located inside the housing 2, and the housing 2 is provided with an air outlet channel 22;
[0153] The lower base 3 is connected to the housing 2 to form a receiving cavity, and an air intake channel 31 is provided on the lower base 3;
[0154] The atomizing core assembly described in the first aspect is disposed within the receiving cavity, and the atomizing core assembly forms a sealed fit with the housing 2;
[0155] The liquid absorption surface 12 of the porous body 1 is connected to the liquid storage chamber 21, and the space between the atomizing surface 11 of the porous body 1 and the lower base 3 forms an atomizing cavity, which is connected to the air inlet channel 31; the smoke channel 13 is connected to the air outlet channel 22 and the atomizing cavity respectively.
[0156] The electronic cigarette atomizing device of this application embodiment includes a housing 2, one end of which has an air outlet, and the other end of which is an open end. The housing 2 has an air outlet channel 22 connected to the air outlet, which allows air mixed with atomized smoke to flow out from the atomizing component. It also includes a liquid storage chamber 21, which is disposed within the housing 2 and is used to contain liquid matrix such as e-liquid. The electronic cigarette atomizing device further includes a lower base 3 and the atomizing core assembly as described above. The lower base 3 covers the open end of the housing 2 and has an air inlet channel 31 communicating with the outside. The atomizing core assembly is disposed within the housing 2, forming a sealed fit with the housing 2. The liquid absorption surface 12 of the porous body 1 communicates with the liquid storage chamber 21, and the space between the atomizing surface 11 of the porous body 1 and the lower base 3 forms an atomizing cavity, which communicates with the air inlet channel 31. The smoke channel 13 communicates with both the air outlet channel 22 and the atomizing cavity. In practical applications, air enters the atomizing chamber inside the housing 2 through the air intake channel 31, passes through the atomizing core, and finally flows out through the air outlet channel 22.
[0157] The working principle of the electronic cigarette atomizing device provided in this application embodiment is as follows: the e-liquid stored in the e-cigarette liquid storage tank 21 continuously permeates to the liquid absorption surface of the porous body 1, and the liquid absorption surface absorbs the e-liquid and conducts it to the atomizing surface; when the user uses the electronic cigarette atomizing device to inhale, the internal sensor is triggered, thereby sending a signal to drive the heating element component set on the atomizing surface to heat the e-liquid to generate an aerosol. The e-liquid is heated and atomized in the atomizing chamber, and the external airflow enters through the air intake channel 31 of the lower base 3, taking away the smoke in the atomizing chamber, and then through the air outlet channel 22 in the housing 2, and finally enters the user's mouth from the air outlet.
[0158] In one embodiment, the electronic cigarette atomizing device described in this application further includes a lower base seal 32, which abuts against the inner wall of the housing 2 and forms a seal between the lower base 3 and the inner wall of the housing 2.
[0159] In one embodiment, the electronic cigarette atomizing device described in this application further includes a conductive nail 5, which passes through the lower base 3 and contacts the heating element 10 to form an electrical connection.
[0160] In one embodiment, the electronic cigarette has fewer internal components, making assembly simpler and production more efficient. Simultaneously, the electronic cigarette's housing has a larger space, allowing for the placement of a larger oil-absorbing element 4, thereby improving the liquid absorption capacity within the atomization chamber.
[0161] According to a third aspect of this application, an electronic cigarette is provided. The electronic cigarette includes the electronic atomizing device and power source described in the second aspect.
[0162] According to an embodiment of this application, when a user uses an electronic cigarette, the user inhales through the outlet. External air enters the atomizing chamber through the air intake channel 31. The sensor inside the electronic cigarette senses the user's inhalation action, the electrical connection between the power supply and the heating element 10 is established, and power is supplied to the heating element assembly to heat the liquid in the atomizing reservoir 21 to form smoke. Air enters the atomizing chamber, carrying the smoke through the outlet channel 22, and is inhaled by the user.

As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment.
