[0062] 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.

[0063] Figures 1 to 3 The present invention illustrates an electronic cigarette heating element 12 according to some embodiments. This heating element 12 can be used in an electronic cigarette atomizer to heat and atomize e-liquid. It may include a porous body 121 for drawing e-liquid from the atomizer's reservoir and a heating element 122 for heating and atomizing the e-liquid adsorbed in the porous body 121. The heating element 122 includes an elongated sheet-like heating portion embedded in the porous body 121, such that all or most of the surface area of ​​the sheet-like heating portion is in contact with the porous body 121. This results in high atomization efficiency, low heat loss, and prevention or significant reduction of dry burning.

[0064] Preferably, the sheet-like heating element is embedded in the porous body 121 with its width direction aligned with the direction of movement of the e-liquid and / or vapor within the porous body 121. This allows for smoother movement of the e-liquid and / or vapor, and also concentrates more heat near the atomizing surface 1211, rather than transferring more heat towards the absorption surface 1212, thereby improving heat utilization. In some embodiments, the porous body 121 may be made of a hard capillary structure such as porous ceramic, porous glass-ceramic, or porous glass. In some embodiments, the sheet-like heating element of the heating body 122 may be made of stainless steel, nickel-chromium alloy, iron-chromium-aluminum alloy, or titanium.

[0065] When the porous body 121 has a sintered structure, the sheet-like heating element 122 can be integrally formed with the heating element of the porous body 121 through sintering. Specifically, taking porous ceramic as an example, when the sheet-like heating element is a metal sheet, the porous body 121 blank can be formed first using kaolin clay, then the sheet-like heating element of the heating element 122 can be embedded in the blank, and then the blank can be dried and sintered. When the sheet-like heating element is a coated sheet-like heating element, the sheet-like heating element can be coated on an organic film first, then the organic film with the sheet-like heating element can be inserted into the blank, and then the blank can be dried and sintered. The organic film will be burned off during the sintering process, leaving only the coated sheet-like heating element tightly bonded to the porous body.

[0066] Compared to a heating wire, a sheet-like heating element has a larger specific surface area. While meeting certain mechanical performance requirements, its thickness can be significantly smaller than the diameter of the heating wire (which is prone to breakage if the diameter is too small). This allows the sheet-like heating element to be made very thin, resulting in less internal heat accumulation and higher atomization efficiency. For example, in some embodiments, the thickness of this sheet-like heating element can be 0.04-0.1 mm, and its width can be 0.3 mm-0.6 mm. In some cases, the thickness of the sheet-like heating element can be even smaller, for example, around 0.008 mm.

[0067] As shown in the figure, the porous body 121 may be generally, but not limited to, cuboid in shape in some embodiments, and includes an atomizing surface 1211 and a liquid-absorbing surface 1212 parallel to the atomizing surface 1211. The liquid-absorbing surface 1212 is used to communicate with the liquid storage chamber so that the e-liquid can enter the porous body 121. The e-liquid is atomized after being heated in the porous body 121 and then escapes through the atomizing surface 1211. The porous body 121 includes a receiving groove 1210 for accommodating the sheet-like heating part of the heating element 122. The receiving groove 1210 extends in length along a direction parallel to the plane where the atomizing surface 1211 is located, and extends in depth in a direction away from the atomizing surface 1211.

[0068] In some embodiments, since the liquid absorption surface 1212 and the atomizing surface 1211 are parallel to each other, the movement direction of the e-liquid and smoke in the porous body 121 is perpendicular to the plane where the atomizing surface 1211 is located. The depth direction of the receiving groove 1210 is perpendicular to the plane where the atomizing surface 1211 is located, so that when the sheet-like heating part of the heating element 122 is housed therein, its width direction is also perpendicular to the plane where the atomizing surface 1211 is located. When the width direction of the sheet-like heating part of the heating element 122 is perpendicular to the atomizing surface 1211, on the one hand, the movement of smoke and e-liquid in the porous body 121 will be smoother, and on the other hand, it is easier to manufacture. In addition, the main heat-conducting surfaces of the sheet-like heating part of the heating element 122 (i.e., the front surface and the rear surface defined by the length and width) are located in the transverse direction and are used to heat the e-liquid near the atomizing surface 1211, resulting in high atomization efficiency. Furthermore, since the sheet-like heating part of the heating element 122 is relatively thin, and the upper and lower surfaces of its thickness and length defining surfaces are relatively small, the e-liquid far from the atomizing surface 1211 absorbs less heat, which can reduce heat waste and save energy.

[0069] Understandably, the sheet-like heating portion of the heating element 122 is not limited to being completely perpendicular to the plane containing the atomizing surface 1211 in its width direction. In some embodiments, a slight inclination is also preferable, that is, the sheet-like heating portion of the heating element 122 can be approximately perpendicular to the atomizing surface 122. Preferably, the angle between the width direction of the sheet-like heating portion of the heating element 122 and the normal direction of the atomizing surface 1211 is within 20 degrees.

[0070] Furthermore, it can be understood that the sheet-like heating portion of the heating element 122 does not uniformly adopt a unique, approximately perpendicular correspondence with the plane containing the atomizing surface 1211 along its entire length. Having this correspondence in only a portion of the heating portion can provide some of the advantages disclosed in the embodiments. Preferably, it is better for at least half of the heating portion to have this correspondence.

[0071] Understandably, in some embodiments, if the direction of movement of the e-liquid and / or smoke in the porous body 121 is not perpendicular to the plane where the atomizing surface 1211 is located, the arrangement of the sheet-like heating element 122 is preferably adjusted accordingly, so that the width direction of the sheet-like heating element is parallel or aligned with the direction of movement of the e-liquid and / or smoke in the porous body 121.

[0072] In some embodiments, to achieve a more uniform heat distribution, the sheet-like heating portion of the heating element 122 needs to be evenly distributed within the porous body 121 near the atomizing surface 1211. In some embodiments, the sheet-like heating portion of the heating element 122 can be S-shaped in the length direction, comprising a plurality of parallel and equally spaced straight portions 1221 and a plurality of curved portions 1222 connecting these straight portions 1221 in series. Correspondingly, the receiving groove 1210 is also S-shaped, and its size is adapted to the size of the sheet-like heating portion of the heating element 122, so that the sheet-like heating portion of the heating element 122 can be well accommodated therein and in close contact with the sheet-like heating portion of the heating element 122. It is understood that the sheet-like heating portion of the heating element 122 is not limited to being designed in an S-shape; it can also be configured as a straight strip, a tape measure shape, a wavy shape, or other shapes as needed. Furthermore, a porous body 121 may contain not only one sheet-like heating element 122, but also two or more.

[0073] See also Figure 4 In some embodiments, the width of the sheet-like heating element 122 is equal to the depth of the receiving groove 1210. When the sheet-like heating element 122 is housed in the receiving groove 1210 along its width direction, its top surface is flush with the atomizing surface 1211, that is, the plane containing the sheet-like heating element 122 is parallel to the atomizing surface 1211. Because the top surface (the upper surface defined by the length and thickness) of the sheet-like heating element 122 is exposed, the heating assembly 12 can atomize the e-liquid near the top surface more quickly, and has the advantages of fast smoke output and convenient manufacturing.

[0074] In some embodiments, the thermal conductivity of the porous body 121 is uniform from the liquid absorption surface 1212 to the atomizing surface 1211. In other embodiments, the thermal conductivity of the porous body 121 increases from the liquid absorption surface 1212 toward the atomizing surface 1211. Therefore, the e-liquid in the porous body 121 closer to the atomizing surface 1211 atomizes faster, which can accelerate the movement of the e-liquid toward the atomizing surface 1211 and improve atomization efficiency.

[0075] Furthermore, the sheet-like heating element 122 is embedded in the porous body 121 along its width direction. This results in a large contact area between the sheet-like heating element 122 and the porous body 121, leading to high heating efficiency and a more secure bond that prevents it from detaching. Additionally, this configuration allows the sheet-like heating element 122 to be made as thin as possible, with a narrow exposed portion, thus significantly reducing the risk of dry burning in the exposed area.

[0076] Figure 5Heating element 12a in some embodiments of the present invention is shown. This heating element 12a is an alternative to the heating element 12 described above. Its main difference from the heating element 12a is that the width of the sheet-like heating portion of the heating element 122a is less than the depth of the receiving groove 1210a. Therefore, when the sheet-like heating portion of the heating element 122a is received in the receiving groove 1210a along its width direction, its top surface is lower than the atomizing surface 1211a. This configuration allows liquid to accumulate in the channel from the top surface to the atomizing surface 1211a, preventing the top surface from being exposed and further reducing the possibility of dry burning.

[0077] Figure 6 The present invention illustrates a heating element 12b in some embodiments, which serves as an alternative to the heating element 12 described above. The main difference between the heating element 12b and the heating element 12b is that the width of the sheet-like heating portion of the heating element 122b is greater than the depth of the receiving groove 1210b. Therefore, when the sheet-like heating portion of the heating element 122b is received in the receiving groove 1210b along its width direction, its top surface protrudes beyond the atomizing surface 1211b. This configuration allows for multiple atomization temperatures, achieving a diverse range of flavors to meet the needs of different users.

[0078] Figure 7 Heating element 12c is shown in some embodiments of the present invention. Heating element 12a is an alternative to heating element 12 described above. The main difference between heating element 12a and heating element 12a is that the width direction of the sheet-like heating part of heating element 122c is perpendicular to the atomizing surface 1211c and is completely embedded in the porous body 121c. This configuration can avoid the problem of dry burning of heating element 122c.

[0079] Figure 8 The illustration shows a heating element 12d in some embodiments of the present invention. The width of the sheet-like heating portion of the heating element 122d is equal to the depth of the receiving groove 1210d. When the sheet-like heating portion of the heating element 122d is received in the receiving groove 1210d along its width direction, its top surface is flush with the atomizing surface 1211d. As an alternative to the heating element 12 described above, its main difference from the heating element 12 is that the thickness of the sheet-like heating portion of the heating element 122d increases along the depth direction of the receiving groove 1210d, causing the resistance of the sheet-like heating portion of the heating element 122d to decrease along the depth direction of the receiving groove 1210d.

[0080] Figure 9The diagram illustrates a heating element 12e in some embodiments of the present invention. The width of the sheet-like heating portion of the heating element 122e is equal to the depth of the receiving groove 1210e. When the sheet-like heating portion of the heating element 122e is received in the receiving groove 1210e along its width direction, its top surface is flush with the atomizing surface 1211e. As an alternative to the heating element 12 described above, its main difference from the heating element 12 is that the thickness of the sheet-like heating portion of the heating element 122e decreases along the depth direction of the receiving groove 1210e, causing the resistance of the sheet-like heating portion of the heating element 122e to increase along the depth direction of the receiving groove 1210e.

[0081] Figure 10 The present invention illustrates a heating element 12f in some embodiments. The width of the sheet-like heating portion of the heating element 122f is equal to the depth of the receiving groove 1210f. When the sheet-like heating portion of the heating element 122f is received in the receiving groove 1210f along its width direction, its top surface is flush with the atomizing surface 1211f. As an alternative to the heating element 12, its main difference from the heating element 12 is that the thickness of the sheet-like heating portion of the heating element 122f near the atomizing surface 1211f is greater than the thickness of the portion away from the atomizing surface 1211f. That is, the thickness of the sheet-like heating portion of the heating element 122f is stepped, which makes the resistance of the sheet-like heating portion of the heating element 122f near the atomizing surface 1211f greater than the resistance of the portion away from the atomizing surface 1211f.

[0082] Figure 11 The present invention illustrates a heating element 12g in some embodiments. The width of the sheet-like heating portion of the heating element 122g is equal to the depth of the receiving groove 1210g. When the sheet-like heating portion of the heating element 122g is received in the receiving groove 1210g along its width direction, its top surface is flush with the atomizing surface 1211g. As an alternative to the heating element 12, its main difference from the heating element 12 is that the thickness of the sheet-like heating portion of the heating element 122g near the atomizing surface 1211g is less than the thickness of the portion away from the atomizing surface 1211g, resulting in a lower resistance of the sheet-like heating portion of the heating element 122g near the atomizing surface 1211g than the resistance of the portion away from the atomizing surface 1211g.

[0083] Figure 12The present invention illustrates a heating element 12h in some embodiments. The width of the sheet-like heating portion of the heating element 122h is equal to the depth of the receiving groove 1210h. When the sheet-like heating portion of the heating element 122h is received in the receiving groove 1210h along its width direction, its top surface is flush with the atomizing surface 1211h. As an alternative to the heating element 12 described above, its main difference from the heating element 12 is that the porous body 121h includes a first layer 1213h near the atomizing surface 1211h and a second layer 1214h away from the atomizing surface 1211h. The thermal conductivity of the first layer 1213h is greater than that of the second layer 1214h, which allows heat to be transferred faster in the area near 1211h, resulting in better atomization efficiency.

[0084] Figure 13 The present invention illustrates a heating element 12i in some embodiments. The width of the sheet-like heating portion of the heating element 122i is equal to the depth of the receiving groove 1210i. When the sheet-like heating portion of the heating element 122i is received in the receiving groove 1210i along its width direction, its top surface is flush with the atomizing surface 1211i. As an alternative to the heating element 12 described above, its main difference is that the straight portions 1221i of the sheet-like heating portion of the heating element 122i are spaced further apart in the direction parallel to the plane containing the atomizing surface, resulting in more uniform heating. Understandably, in some embodiments, the spacing of the straight portions 1221i of the sheet-like heating portion of the heating element 122i in the direction parallel to the plane containing the atomizing surface can also be spaced further apart in the middle.

[0085] Figure 14 The present invention illustrates a heating element 12j in some embodiments, wherein the width of the sheet-like heating portion of the heating element 122j is equal to the depth of the receiving groove 1210j, and when the sheet-like heating portion of the heating element 122j is received in the receiving groove 1210j along its width direction, its top surface is flush with the atomizing surface 1211j. As an alternative to the heating element 12, its main difference lies in the fact that the straight portions 1221j of the sheet-like heating portion of the heating element 122j have a thickness distribution that is thicker in the middle and thinner at the edges in the direction parallel to the plane containing the atomizing surface.

[0086] Figure 15 The illustration shows a heating element 12k in some embodiments of the present invention. The width of the sheet-like heating portion of the heating element 122k is equal to the depth of the receiving groove 1210k. When the sheet-like heating portion of the heating element 122k is received in the receiving groove 1210k along its width direction, its top surface is flush with the atomizing surface 1211k. As an alternative to the heating element 12 described above, its main difference from the heating element 12 is that the liquid absorption surface 1212k and the atomizing surface 1211k are not parallel, making the porous body 121k trapezoidal.

[0087] Figure 16 The illustration shows a heating element 12m in some embodiments of the present invention. The width of the sheet-like heating portion of the heating element 122m is equal to the depth of the receiving groove 1210m. When the sheet-like heating portion of the heating element 122m is received in the receiving groove 1210m along its width direction, its top surface is flush with the atomizing surface 1211m. As an alternative to the heating element 12 described above, its main difference from the heating element 12 is that the liquid absorption surface 1212m is a concave arc shape.

[0088] Figure 17 The present invention illustrates a heating element 12n in some embodiments. As an alternative to the heating element 12 described above, the main difference lies in that: as an alternative to the heating element 12, the porous body 121n of this heating element 12n includes three atomizing surfaces 1211n and three liquid-absorbing surfaces 1212n. Each atomizing surface 1211n corresponds to a sheet-like heating element 122n. The width of the sheet-like heating element 122n is equal to the depth of the corresponding receiving groove 1210n. When the sheet-like heating element 122n is received in the receiving groove 1210n along its width direction, its top surface is flush with the atomizing surface 1211n. Each liquid-absorbing surface 1212n is parallel to the corresponding atomizing surface 1211n. It can be understood that the number of atomizing surfaces 1211n can also be two or more.

[0089] Figure 18 The diagram illustrates a sheet-like heating element 122p in some embodiments of the present invention. As an alternative to the heating element 122 of the aforementioned heating assembly 12, the main difference is that the heating element 122p includes a longitudinally elongated sheet-like heating element in the middle and two electrical connection portions 1223p and 1224p respectively connected to both ends of the heating element. The longitudinally elongated sheet-like heating element is not bent into a specific shape in the diagram, but is presented as a long strip. In some embodiments, the heating element is integrally formed with the two electrical connection portions 1223p and 1224p, and the lower portions of the two electrical connection portions 1223p and 1224p protrude from the lower edge of the heating element, so that the sheet-like heating element 122p can be inserted into the porous body. The two electrical connection portions 1223p and 1224p are inserted more deeply, thus forming a more secure bond with the porous body to prevent loosening caused by lead wire pulling. The upper portions of the two electrical connection portions 1223p and 1224p protrude from the upper edge of the heating element, serving as electrical leads.

[0090] Figure 19The diagram illustrates a sheet-like heating element 122q in some embodiments of the present invention. This sheet-like heating element 122q is configured as an S-shaped strip, comprising a plurality of parallel straight portions 1221q and a plurality of curved portions 1222q connected in series with these straight portions 1221q. As an alternative to the sheet-like heating element 122 of the heating assembly 12 described above, the main difference is that the thickness of the curved portions 1222q of the sheet-like heating element 122q is greater than the thickness of the straight portions 1221q, thereby reducing the resistance of the curved portions 1222q and thus reducing heat accumulation at the curved portions 1222q. In some embodiments, the resistance at the corner can also be reduced by widening the curved portions 1222q. It is understood that this solution is not limited to sheet-like heating elements; heating wires and coated sheet-like heating elements can also be applied. Specifically, when the heating wire has both straight and curved portions, the curved portions can be designed to be larger. For coated heating elements, the coating can be thicker or wider at the bends.

[0091] Figure 20 The diagram illustrates a sheet-like heating element 122r in some embodiments of the present invention. As an alternative to the sheet-like heating element 122 described above, the main difference is that the sheet-like heating element 122r has a plurality of through holes 1220r extending through the thickness direction. These through holes 1220r are distributed in a denser manner in the middle and sparser at both ends along the length of the sheet-like heating element 122r, so that the resistance of the sheet-like heating element 122r in the length direction is high in the middle and low at both ends, in order to meet the needs of specific heating components and to ensure that the heat distribution in the porous body can meet specific requirements.

[0092] Figure 21 The diagram shows a sheet-like heating element 122s in some embodiments of the present invention. As an alternative to the sheet-like heating element 122s described above, the main difference is that the sheet-like heating element 122s has a plurality of through holes 1220s extending through the thickness direction. These through holes 1220s are distributed in a sparse middle and denser end direction along the length of the sheet-like heating element 122s, so that the resistance of the sheet-like heating element 122s in the length direction is low in the middle and high at both ends, in order to meet the needs of specific heating components.

[0093] Figure 22The diagram shows a sheet-like heating element 122t in some embodiments of the present invention. As an alternative to the sheet-like heating element 122t described above, the main difference is that the sheet-like heating element 122t is provided with a plurality of through holes 1220t extending through the thickness direction. The distribution density of these through holes 1220t in the width direction of the sheet-like heating element 122t gradually changes (e.g., gradually increases or decreases) or changes in a step, so that the resistance of the sheet-like heating element 122t in the width direction gradually changes or changes in a step, so as to adapt to the needs of different heating components.

[0094] Figure 23 The sheet-like heating element 122u in some embodiments of the present invention is shown. As an alternative to the sheet-like heating element 122, the main difference is that the sheet-like heating element 122u is a heating mesh, which includes a plurality of mesh holes 1220u. The distribution of these mesh holes 1220u in the length direction of the sheet-like heating element 122u includes: (1) uniform distribution, so that the resistance distribution in the length direction is uniform; (2) sparse in the middle and dense at both ends, and the change is gradual or stepped; (3) dense in the middle and sparse at both ends, and the change is gradual or stepped. The distribution of these mesh holes 1220u in the width direction of the sheet-like heating element 122u includes: (1) uniform distribution; (2) sparse on one side and dense on the other side, and the change is gradual or stepped.

[0095] Figure 24 and Figure 25 The figure illustrates a heating element 12v according to some embodiments of the present invention. As shown, the heating element 12v includes a porous body 121v and a sheet-like heating element 122v disposed within the porous body 121v. As shown, as an alternative to the above-described heating element 12v, the main difference is that the liquid-absorbing side surface of the porous body 121v of the heating element 12v is recessed to form a groove 120v, making the overall shape bowl-shaped. The inner surface of the bottom wall of the porous body 121v forms a liquid-absorbing surface 1212v, and the outer surface of the bottom wall forms an atomizing surface 1211v. The sheet-like heating element 122v is embedded in the atomizing surface 1211v. The bowl-shaped design of the porous body 121v ensures a sufficiently high overall height, facilitating the installation of the heating element 12v and the installation of the sealing sleeve 115. Furthermore, it ensures that the distance between the liquid-absorbing surface 1212v and the atomizing surface 1211v is sufficiently close, facilitating installation while maintaining atomization effectiveness. The heating element 122V can be any of the heating elements mentioned above.

[0096] Figure 26 and Figure 27 An electronic cigarette according to some embodiments of the present invention is shown, which employs... Figure 24 and Figure 25The heating element 12V shown can be understood to be any of the other heating elements described above that can also be used in this electronic cigarette. In some embodiments, the electronic cigarette may be flat and may include an atomizer 1 and a battery assembly 2 detachably connected to the atomizer 1. The atomizer 1 is used to contain e-liquid and generate vapor, and the battery assembly 2 is used to power the atomizer 1. As shown, the lower end of the atomizer 1 is inserted into the upper end of the battery assembly 2, and the two can be magnetically connected.

[0097] like Figure 28 As shown, in some embodiments, the atomizer 1 may include an atomizing component 10 and a liquid storage device 20 fitted onto the atomizing component 10. The atomizing component 10 can be used to heat and atomize e-liquid, and the liquid storage device 20 can be used to store e-liquid for supply to the atomizing component 10.

[0098] See also Figures 29 to 32 The atomizing assembly 10 includes a lower seat 11, a heating element 12v disposed on the lower seat 11, a sealing sleeve 13 sleeved on the heating element 12v, an upper seat 14 disposed on the lower seat 11 and pressing against the sealing sleeve 13, and a sleeve 15 sleeved on the upper seat 14. After the upper seat 14 presses against the sealing sleeve 13, it tightly clamps the heating element 12v between the lower seat 11 and the upper seat 14. The presence of the sealing sleeve 13 can achieve a seal between the heating element 12v and the upper seat 14 to prevent leakage; it can also make the horizontal positioning of the heating element 12v more secure.

[0099] In some embodiments, the lower body 11 may include a base 111, a first support arm 112 erected on the top surface of the base 111, and a second support arm 113 erected on the top surface of the base 111 and disposed opposite to the first support arm 112. The heating element 12v is supported between the first support arm 112 and the second support arm 113, with its atomizing surface 1211v facing the base 111 and having a certain gap between it and the base 111. This gap forms an atomizing chamber 110 for mixing smoke and air.

[0100] In some embodiments, the base 111 may be a rectangular flat plate with two recessed grooves 1110 on its bottom surface for housing two magnetic elements 16, which are used to magnetically attach the atomizer 1 to the battery assembly 2. The base 111 also has hooks 1112 on its two opposite end faces for engaging with the liquid storage device 20. The bottom of the base 111 may also have two electrode posts 1114 electrically connected to the heating element 12V, for connecting to the positive and negative terminals of the battery assembly 2, respectively.

[0101] In some embodiments, the first support arm 112 and the second support arm 113 may be plate-shaped. The inner surfaces of the first support arm 112 and the second support arm 113 are respectively recessed to form receiving grooves 1122 and 1132, for the nesting portion 142 of the upper seat 14 to be embedded therein. The receiving grooves 1122 and 1132 are formed on the upper half of the first support arm 112 and the second support arm 113, and steps 1126 and 1136 are formed on the first support arm 112 and the second support arm 113, respectively. The two ends of the heating element 12v respectively overlap the steps 1126 and 1136. The outer sides of the top ends of the first support arm 112 and the second support arm 113 are respectively provided with engaging portions 1122 and 1132 for engaging with the upper seat 14. In some embodiments, the first support arm 112 and the second support arm 113 are arranged symmetrically from left to right to facilitate assembly; that is, during assembly, the assembler does not need to first distinguish which end is left and which end is right.

[0102] In some embodiments, the lower body 11 may also include a U-shaped air inlet structure 114 and a U-shaped air outlet structure 115. The air inlet structure 114 and the air outlet structure 115 are respectively connected to the outer sides of the first support arm 112 and the second support arm 113, and both extend horizontally outward. The first support arm 112 has a through hole 1120 that connects the air inlet structure 114 to the atomizing chamber 110, and the second support arm 113 has a through hole 1130 that connects the air outlet structure 115 to the atomizing chamber 110, so as to introduce air to carry away the smoke in the atomizing chamber 110; the through holes 1120 and 1130 are respectively located below the receiving grooves 1122 and 1132.

[0103] In some embodiments, the upper seat 14 may include a generally rectangular main body 141, a nesting portion 142 extending downward from the center of the bottom surface of the main body 141, and a second air intake channel 143 extending downward from the right end of the bottom surface of the main body 141. The nesting portion 142 is annular and is housed in receiving grooves 1122 and 1132 between the first support arm 112 and the second support arm 113 of the lower seat 111, and is fitted around the sealing sleeve 13. The upper seat 14 also includes two liquid channels 144 extending from the top surface to the bottom surface of the main body 141, a channel 145 formed on the sidewall surrounding the right liquid channel 144 and communicating with the second air intake channel 143, and a second air outlet channel 146 communicating with the channel 145. The second air outlet channel 146 extends through the center of the top surface of the upper seat 14 and communicates with the channel 145. The upper seat 14 has two recessed holes 147 on its top left end, which cooperate with the sleeve 15 to provide positioning and anti-fouling functions. The upper seat 14 also includes a downwardly extending hook 148 to hook onto the lower seat 11.

[0104] In some embodiments, the sleeve 15 may be a silicone sleeve, which may include a top wall 151, an annular first baffle 152 extending downward from the periphery of the top wall 151, and two U-shaped second baffles 153 and 154 extending downward from both ends of the first baffle 152, respectively. The top wall 151 has two liquid inlet holes 155 and a sleeve vent channel 156. The two liquid inlet holes 155 correspond to the two liquid channels 144 of the upper seat 14, respectively. The sleeve vent channel 156 is inserted into and communicates with the second vent channel 146 of the upper seat 14. The first baffle 152 covers the side wall of the main body 141 of the upper seat 112, covering the groove 145 on the side wall to form a closed annular upper seat connection channel. The second baffles 153 and 154 respectively cover the air inlet structure 1114 and air outlet structure 1115 of the lower seat 111, forming a sealed first air inlet channel and a first air outlet channel together with the first support arm 112 and the second support arm 115. A first air inlet hole 157 is formed on the left side of the second baffle 153, which is used to connect with the external environment to introduce air into the first air inlet channel. The first air outlet channel is connected to the second air inlet channel 143. Two positioning posts 158 extend downward from the left end of the bottom surface of the top wall 151 of the sleeve 15 to cooperate with the two positioning holes 147 of the upper seat 14, mainly to ensure that the first air inlet hole 157 on the left side of the sleeve 15 is accurately located on the left side of the combination of the upper seat 112 and the lower seat 111, ensuring that it is connected to the first air inlet channel and serving as a foolproof function.

[0105] The liquid storage device 20 includes a housing 21 with an air outlet 210 and an airflow pipe 22 disposed in the housing 21 and communicating with the air outlet 210. The housing 21 includes a liquid storage part 211 and a sleeve part 212 connected to the liquid storage part 211. A liquid storage cavity 23 is formed between the liquid storage part 211 and the airflow pipe 22. The liquid storage cavity 23 includes an outlet 230. The sleeve part 212 is connected to the periphery of the outlet 230 and is used to tightly fit onto the atomizing assembly 10. A step 213 is formed between the inner wall surface of the sleeve part 212 and the inner wall surface of the liquid storage part 211. The step 213 abuts against the top surface of the atomizing assembly 10. In some embodiments, the sleeve part 212 is integrally formed with the liquid storage part 211. The air outlet 210 can be configured as a flat, trumpet-shaped nozzle.

[0106] The airflow duct 22 extends from the air outlet 210 toward the liquid outlet 230, and its end extends into the sleeve portion 212, where it is inserted into the air outlet 156 of the sleeve body 15, thereby connecting with the second air outlet channel 146. The sleeve portion 212 also has second air inlets 2120 on its left and right sides, with the second air inlet 2120 on the left side connecting with the first air inlet 157 of the sleeve body 15, allowing air from outside the housing 21 to enter the first air inlet channel formed by the sleeve body 15 and the lower seat 11. Preferably, the housing 21 is symmetrically arranged to facilitate assembly; otherwise, if only one side has a second air inlet 2120, the assembly process would require an additional step of determining whether the second air inlet 2120 is on the same side as the first air inlet 157. The inner walls on the left and right sides of the sleeve 212 are also provided with slots 2122, which are respectively engaged with the hooks 1112 of the lower seat 111, so that the housing 21 and the lower seat 111 can be easily snapped together.

[0107] When assembling atomizer 1, the following steps can be taken:

[0108] (1) First, put the sealing sleeve 13 on the heating element 12V;

[0109] (2) Insert the assembly of the sealing sleeve 13 and the heating element 12v into the nesting part 142 of the upper body 14;

[0110] (3) Then place the upper seat 14 on the lower seat 11, so that the hook 148 of the heating component of the upper seat 14 is engaged with the engagement part 1122, 1132 of the lower seat 11, so as to realize the engagement connection between the upper seat 14 and the lower seat 11; at the same time, make the electrode lead of the heating component 12V electrically connected to the electrode post 1114 on the lower seat 11.

[0111] (4) Then attach the sleeve 15 onto the upper seat 14 to complete the assembly of the atomizing component 10;

[0112] (5) Finally, insert it upside down into the sleeve part 212 of the liquid storage device 20 containing e-liquid, with the top surface abutting against the step 213, blocking the liquid outlet 230 of the liquid storage chamber 23, and let the hook 1112 of the lower seat 11 engage in the slot 2122 of the sleeve part 212 to realize the assembly of the atomizer 1. The assembly is very convenient and quick.

[0113] Therefore, the air flow path in atomizer 1 is as follows: Figure 32As indicated by the arrows: Air first enters the first air intake channel through the second air intake hole 2120 and the first air intake hole 157, and then enters the atomizing chamber 110 through the through hole 1120 to mix with the smoke. The smoke-air mixture then enters the first air outlet channel through the through hole 1130, and then enters the second air intake channel 143. It then enters the annular upper body connecting channel, and then enters the second air outlet channel 1466. Finally, it enters the airflow pipe 22, and is finally discharged from the atomizer 1 through the air outlet 210. The e-liquid in the liquid storage chamber 23 passes sequentially through the liquid inlet hole 155 of the sleeve 15 and the liquid channel 144 of the upper body 14, and enters the groove 120 of the heating element 12v, contacting the liquid absorption surface 1212v to achieve liquid delivery.

[0114] In some embodiments, the second air inlet 2120 is positioned higher than the atomizing chamber 110. This arrangement effectively prevents leaked e-liquid from flowing out of the second air inlet 2120 during normal use. The bottom of the entire airflow channel of the atomizer 1 is approximately U-shaped, and the airflow direction at the atomizing chamber 110 is parallel to the atomizing surface 1211v of the heating element 12v, making it easier to carry away the smoke atomized by the atomizing surface 1211v.

[0115] In some embodiments, the top surface of the porous body 121v of the heating element 12v has a groove, which increases the liquid guiding efficiency after the e-liquid enters the groove. Specifically, the groove increases the contact area between the porous body and the e-liquid; furthermore, the distance between the bottom surface of the groove and the bottom outer surface of the porous body 121v is small, thereby reducing the flow resistance of the e-liquid reaching the bottom outer surface of the porous body 121v. Additionally, since the liquid guiding side of the heating element 12v needs to be sealed with a sealing sleeve 115 to prevent the e-liquid from flowing out into the atomizing chamber 110, the porous body 121v needs to have a certain height to meet the requirements of the sealing element and the rigidity requirements of the porous body 121v itself. By setting the above-mentioned groove, both the thickness requirements of the porous ceramic body and the liquid guiding efficiency requirements can be met.

[0116] Understandably, the heating element 12v of the above-mentioned electronic cigarette can also be other suitable heating elements, and the heating part of its heating element 122v is arranged in a longitudinally elongated sheet shape, or it can be in other shapes such as filament.

[0117] Figure 33 The present invention illustrates a heating element 12w in some embodiments. As an alternative to the heating element 12 described above, the main difference is that the porous body 121w of the heating element 12w includes a wavy atomizing surface 1211w. The straight portions 1221w of the sheet-like heating part of the heating element 122w are respectively provided corresponding to the wavy valley bottom of the atomizing surface 1211w and perpendicular to the plane where the wavy atomizing surface 1211w is located, so as to reduce the dry burning effect by the liquid collected at the valley bottom.

[0118] Figure 34 The present invention illustrates a heating element 12x in some embodiments thereof. The width of the sheet-like heating portion of the heating element 122x is less than the depth of the receiving groove 1210x. Therefore, when the sheet-like heating portion of the heating element 122x is received in the receiving groove 1210x along its width direction, its top surface is lower than the atomizing surface 1211x. As an alternative to the heating element 12a described above, the main difference is that the width direction of the sheet-like heating portion of the heating element 122x of the heating element 12x forms an angle with the normal direction of the atomizing surface 1211x, and this angle is preferably less than 20 degrees.

[0119] Figure 35 The illustration shows a heating element 122y in some embodiments of the present invention. The heating element 122y includes a central elongated heating section and two electrical connection sections 1223y and 1224y integrally connected to both ends of the heating section. As an alternative to the heating element 122p, the main difference is that the sheet-like heating section of the heating element 122y has a plurality of through holes or blind holes 1220y near the porous atomizing surface to increase the resistance of that region.

[0120] Figure 36 The present invention illustrates a heating element 122z in some embodiments, which includes a longitudinally elongated sheet-like heating section in the middle and two electrical connection sections 1223z and 1224z integrally connected to both ends of the heating section. As an alternative to the heating element 122p, the main difference is that the heating section of the heating element 122z has a plurality of through holes or blind holes 1220z located away from the porous atomizing surface to increase the resistance of that region.

[0121] Understandably, although the alternatives to the heating element and porous body in the above embodiments mainly describe the differences from the aforementioned embodiments, they can be used interchangeably as long as they do not contradict each other. For example, the heating element in any of the above embodiments can be used in conjunction with the porous body in any of the above embodiments, and any of the above heating components can be applied to electronic cigarettes.

[0122] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
