PREFERRED EXECUTION FORMS

[0026] The preferred embodiments are illustrated in detail with reference to the accompanying drawings in order to provide a clearer understanding of the technical features, purpose and effect of the present disclosure.

[0027] A heating arrangement 12 of an electronic cigarette in some embodiments of the present disclosure is in Fig. 1 to Fig. Figure 3 shows the heating arrangement 12, which can be used in an atomizer of an electronic cigarette to heat and atomize e-liquid. The heating arrangement 12 comprises a porous body 121 for absorbing the e-liquid from a liquid storage cavity of the atomizer and a heating element 122 for heating and atomizing the e-liquid absorbed by the porous body 121. The heating element 122 has an elongated plate heating unit embedded in the porous body 121. All or most of the surface of the plate heating unit is in contact with the porous body 121, resulting in high atomization efficiency, low heat loss, and protection against or prevention of dry firing, etc.

[0028] According to one embodiment, the plate heating element is integrated into the porous body in a lateral direction and following the direction of movement of the e-liquid and / or vapor. This not only makes the movement of the e-liquid and / or vapor smoother but also centralizes more heat around an atomizing side 1211 to improve heat availability, instead of delivering more heat towards a liquid absorption side 1212 along the opposite direction. In some embodiments, the porous body 121 can be made of a hard capillary structure such as porous ceramic, porous glass-ceramic, porous glass, and so on. In some embodiments, the plate heating element 122 can be made of stainless steel, nichrome, iron-chromium-aluminum alloy, titanium, and so on.

[0029] If the porous body 121 has a sintered structure, the heating element 122's plate heating unit can be formed integrally with the heating element of the porous body 121 by sintering. According to one embodiment, in which the porous body 121 is made of porous ceramic, if the heating element is a metal plate, a base of the porous body 121 is first formed using kaolin slurry, and then the heating element 122's plate heating unit is embedded in the base, which is subsequently baked and sintered. If the heating element is a coated heating element, it can be coated with an organic membrane, and the organic membrane is embedded in the base, which is then baked and sintered. The organic membrane is burned away during the sintering process, leaving the coated heating element tightly bonded to the porous body.

[0030] Compared to a heating coil, the plate heating element has a larger surface area. To meet certain mechanical requirements, the thickness of the plate heating element can be significantly smaller than the diameter of the heating coil (a heating coil with too small a diameter is prone to burning out). Therefore, the plate heating element can be very thin, resulting in low internal heat buildup and high atomization efficiency. For example, in some embodiments, the thickness of the plate heating element can range from 0.04 mm to 0.1 mm, and the width from 0.3 mm to 0.6 mm. In some embodiments, the thickness of the plate heating element can be even smaller, reaching approximately 0.008 mm.

[0031] The porous body 121 can, in some embodiments, have the shape of a rectangle, but is not limited to this. The porous body 121 has the atomizing side 1211 and the liquid absorption side 1212 parallel to the atomizing side 1211. The liquid absorption side 1212 is used to connect with the liquid storage cavity, allowing the e-liquid to flow into the porous body 121. The e-liquid is heated and atomized within the porous body 121 and then escapes through the atomizing side 1211. The porous body 121 also has a receiving groove 1210 for receiving the plate heating unit of the heating element 122. The receiving groove 1210 extends parallel to a plane that is parallel to the atomizing side 1211 in a longitudinal direction, while extending away from the atomizing side 1211 in a depth direction.

[0032] In some embodiments, since the liquid absorption side 1212 is parallel to the atomizing side 1211, the directions of movement of the e-liquid and vapor in the porous body 121 are perpendicular to the plane in which the atomizing side 1211 is arranged. The depth direction of the receiving groove 1210 is perpendicular to the plane in which the atomizing side 1211 is arranged, so that when the plate heating unit of the heating element 122 is received in the receiving groove 1210, its width direction is also perpendicular to the plane in which the atomizing side 1211 is arranged. When the width direction of the plate heating unit of the heating element 122 is perpendicular to the atomizing side 1211, the e-liquid and vapor move more smoothly in the porous body 121, and the manufacture of the heating element 122 is facilitated.Additionally, the main heat-conducting surfaces (front and back of the plate heating unit, defined by its length and width) of the heating element 122's plate heating unit are arranged laterally to heat the e-liquid close to the atomizing surface 1211, thus improving atomization efficiency. Furthermore, the e-liquid further away from the atomizing surface 1211 absorbs less heat because the plate heating unit of the heating element 122 is thin and both its upper and lower surface areas, defined by its thickness and length, are small, which reduces heat waste and saves energy.

[0033] It is understood that the plate heating unit of the heating element 122 is not limited to being completely perpendicular to the plane in which the atomizing side 1211 is arranged. According to one embodiment, an angle can be formed, that is, the plate heating unit of the heating element 122 can be substantially perpendicular to the plane in which the atomizing side 1211 is arranged. According to one embodiment, the angle between the lateral direction of the plate heating unit and a normal to the plane is within 20 degrees.

[0034] It is further understood that the plate heating unit is not limited to the embodiment in which the plate heating unit as a whole is substantially perpendicular to the plane in which the atomizing side 1211 is arranged; some advantageous effects disclosed in the present disclosure can be achieved if a part of the plate heating unit of the heating element 122 is perpendicular to the atomizing side 1211. According to one embodiment, at least up to half of the plate heating unit can be substantially perpendicular to the plane.

[0035] It is understood that in some embodiments, if the directions of movement of the e-liquid and / or the smoke in the porous body 121 are not perpendicular to the plane in which the atomizing side 1211 is arranged, the arrangement of the plate heating unit of the heating element 122 can be adjusted accordingly, so that the plate heating unit is as parallel as possible to, or follows, the directions of movement of the e-liquid and / or the smoke in the porous body 121 in the lateral direction.

[0036] In some embodiments, the plate heating unit of the heating element 122 can be distributed as evenly as possible around the atomizing side 1211 within the porous body 121, thus enabling more uniform heat distribution. In some embodiments, the plate heating unit of the heating element 122 can be S-shaped in the longitudinal direction; the plate heating unit has a certain number of parallel, evenly spaced flat parts 1221 and a certain number of bent sections 1222 that connect the flat parts 1211 to one another. Accordingly, the receiving groove 1210 is also S-shaped, and its size is adapted to that of the plate heating unit of the heating element 122, allowing the plate heating unit of the heating element 22 to be securely received in the receiving groove 1210 and to be in close contact with the plate heating unit of the heating element 22.It is understandable that the plate heating unit of the heating element 122 is not limited to being S-shaped; in other embodiments, the plate heating unit of the heating element can have the form of a strip, band, wave, etc. Additionally, in other embodiments, it is conceivable that two or more plate heating units of the heating element 122 can be arranged on the porous body 121.

[0037] As in Fig. As shown in Figure 4, in some embodiments the width of the plate heating unit of the heating element 122 is equal to the depth of the receiving groove 1210.

[0038] An upper surface of the plate heating unit of the heating element 122 is flush with the atomizing side 1211 when the plate heating unit of the heating element 122 is received along its width in the receiving groove 1210; more precisely, the plane in which the plate heating unit is arranged is parallel to the atomizing side 1211. Due to the exposed upper surface (an upper surface defined by its length and thickness) of the plate heating unit of the heating element 122, the heating arrangement 12 can atomize the e-liquid more quickly near the upper surface, thus enabling rapid vapor production and suitable manufacturing of the heating arrangement 12.

[0039] In some embodiments, the thermal conductivity of the porous body 121 is uniform along the direction from the liquid absorption side 1212 to the atomization side 1211. In other embodiments, the thermal conductivity of the porous body 121 gradually increases along the direction from the liquid absorption side 1212 to the atomization side 1211. As a result, the e-liquid is atomized more rapidly as it approaches the atomization side 1211, thus accelerating the movement of the e-liquid towards the atomization side 1211 and improving atomization efficiency.

[0040] Additionally, the plate heating element of the heating element 122 is embedded in the porous body 121 along its width, resulting in a large contact area between the plate heating element and the porous body 121. This provides high thermal efficiency and a strong, durable connection. Furthermore, this arrangement allows the plate heating element of the heating element 122 to be manufactured as thin as possible, and the exposed portion of the plate heating element 122 is relatively narrow, thus significantly reducing drying at the exposed portion.

[0041] In Fig. Figure 5 shows a heating arrangement 12a according to some embodiments. The heating arrangement 12a is an alternative solution to the heating arrangement 12 mentioned above, and the difference lies in the fact that the width of a plate heating unit of a heating element 122a of the heating arrangement 12a is smaller than the depth of a receiving groove 1210a of the heating arrangement 12a. This results in the upper surface of the plate heating unit of the heating element 122a being lower than an atomizing side 1211a when it is received in the receiving groove 1210a along its width direction. Thus, e-liquid can accumulate in a slotted channel between the upper surface and the atomizing side 1211a, which prevents the upper surface from being exposed and further reduces the risk of the heating element 122a drying out.

[0042] In Fig. Figure 6 shows a heating arrangement 12b according to some embodiments. The heating arrangement 12b is an alternative solution to the heating arrangement 12 mentioned above, and the difference lies in the fact that the width of a plate heating unit of a heating element 122b is greater than the depth of a receiving groove 1210b. This results in the upper surface of the plate heating unit being higher than an atomizing side 1211b when the plate heating unit of the heating element 122b is received in the receiving groove 1210b along its width direction. Thus, multiple atomizing temperatures can be provided to achieve different flavors and meet the needs of different customers.

[0043] In Fig. Figure 7 shows a heating arrangement 12c according to some embodiments. The heating arrangement 12c is an alternative solution to the heating arrangement 12 mentioned above, and the difference lies in the fact that a plate heating unit of a heating element 122c is perpendicular in the width direction to an atomizing side 1211c and is completely embedded in a porous body 121c. Thus, the drying out of the heating element 122c can be avoided.

[0044] In Fig. Figure 8 shows a heating arrangement 12d according to some embodiments. The width of a plate heating unit of a heating element 122d of the heating arrangement 12d is equal to the depth of a receiving groove 1210d; when the plate heating unit of the heating element 122d is received in the receiving groove 1210d in the width direction, an upper surface of the plate heating unit is flush with an atomizing side 1211d. As an alternative solution to the heating arrangement 12 mentioned above, the difference between the heating arrangements 12d and 12 lies in the fact that the thickness of the plate heating unit of the heating element 122d gradually increases along a depth direction of the receiving groove 1210d, which causes the resistance of the plate heating unit of the heating element 122d to gradually decrease along the depth direction of the receiving groove 1210d.

[0045] In Fig. Figure 9 shows a heating arrangement 12e according to some embodiments. The width of a plate heating unit of a heating element 122e is equal to the depth of a receiving groove 1210e; when the plate heating unit of the heating element 122e is received in the receiving groove 1210e in the width direction, an upper surface of the plate heating unit is flush with an atomizing side 1211e. As an alternative solution to the heating arrangement 12 mentioned above, the difference between the heating arrangements 12e and 12 lies in the fact that the thickness of the plate heating unit of the heating element 122e gradually decreases along a depth direction of the receiving groove 1210e, which causes the resistance of the plate heating unit of the heating element 122e to gradually increase along the depth direction of the receiving groove 1210e.

[0046] In Fig. Figure 10 shows a heating arrangement 12f in some embodiments. The width of a plate heating unit of a heating element 122f is equal to the depth of a receiving groove 1210f; when the plate heating unit of the heating element 122f is received in the receiving groove 1210f in the width direction, an upper surface of the plate heating unit is flush with an atomizing side 1211f. As an alternative solution to the heating arrangement 12 mentioned above, the difference between the heating arrangements 12f and 12 is that the thickness of a portion of the plate heating unit of the heating element 122f that is located near an atomizing side 1211f is greater than the thickness of a portion of the plate heating unit of the heating element 122f that is located away from the atomizing side 1211f.This means that the plate heating unit of the heating element 122f has a graduated thickness, which results in a greater resistance of the part of the plate heating unit of the heating element 122f that is located near the atomizing side 1211f than the resistance of the part of the plate heating unit of the heating element 122f that is located away from the atomizing side 1211f.

[0047] In Fig. Figure 11 shows a heating arrangement 12g according to some embodiments. The width of a plate heating unit of a heating element 122g is equal to the depth of a receiving groove 1210g; when the plate heating unit of the heating element 122g is received in the receiving groove 1210g in the width direction, an upper surface of the plate heating unit is flush with an atomizing side 1211g.As an alternative solution to the heating arrangement 12 mentioned above, the difference between the heating arrangements 12g and 12 lies in the fact that the thickness of a part of the plate heating unit of the heating element 122g, which is located near the atomizing side 1211g, is smaller than the thickness of a part of the plate heating unit of the heating element 122g, which is located away from the atomizing side 1211g, resulting in a resistance of the part of the plate heating unit of the heating element 122g, which is located near the atomizing side 1211g, being smaller than the resistance of the part of the plate heating unit of the heating element 122g, which is located away from the atomizing side 1211g.

[0048] In Fig. Figure 12 shows a heating arrangement 12h according to some embodiments. The width of a plate heating unit of a heating element 122h is equal to the depth of a receiving groove 1210h; when the plate heating unit of the heating element 122h is received in the receiving groove 1210h in the width direction, an upper surface of the plate heating unit is flush with an atomizing side 1211h.As an alternative solution to the heating arrangement 12 mentioned above, the difference between heating arrangements 12h and 12 lies in the fact that a porous body 121h has a first layer 1213h located near the atomizing side 1211h and a second layer 1214h located away from the atomizing side 1211h, and a thermal conductivity of the first layer 1213h is greater than that of the second layer 1214h, which allows the heat to be transferred faster in the part of the plate heating unit located near the atomizing side 1211h and thus optimizes the atomization efficiency.

[0049] In Fig. Figure 13 shows a heating arrangement 12i according to some embodiments. The width of a plate heating unit of a heating element 122i is equal to the depth of a receiving groove 1210i; when the plate heating unit of the heating element 122i is received in the receiving groove 1210i in the width direction, an upper surface of the plate heating unit is flush with an atomizing side 1211i. As an alternative solution to the heating arrangement 12 mentioned above, the difference between the heating arrangements 12i and 12 lies in the fact that the density of flat parts 1221i of the heating element 122i, which are arranged in the center of a plane parallel to the atomizing side 1211i, is lower than that of the flat parts 1221i, which are arranged in other regions of the plane, thus enabling uniform heating of the heating element 122i.It is understood that in some embodiments the density of the flat parts 1221i arranged in the middle of the plane may be greater than that of the flat parts 1221i arranged in other areas of the plane.

[0050] In Fig. Figure 14 shows a heating arrangement 12j according to some embodiments. The width of a plate heating unit of a heating element 122j is equal to the depth of a receiving groove 1210j; when the plate heating unit of the heating element 122j is received in the receiving groove 1210j in the width direction, an upper surface of the plate heating unit is flush with an atomizing side 1211j. As an alternative solution to the heating arrangement 12 mentioned above, the difference between the heating arrangements 12j and 12 is that the thicknesses of flat parts 1221j of the heating element 122j, which are arranged in the middle of a plane parallel to an atomizing side 1211j, are each greater than the thicknesses of the flat parts 1221j, which are arranged in other regions of the plane.

[0051] In Fig. Figure 15 shows a heating arrangement 12k according to some embodiments. The width of a plate heating unit of a heating element 122k is equal to the depth of a receiving groove 1210k. When the plate heating unit of the heating element 122k is received in the receiving groove 1210k in the width direction, an upper surface of the plate heating unit is flush with an atomizing side 1211k. As an alternative solution to the heating arrangement 12 mentioned above, the difference between the heating arrangements 12k and 12 is that a liquid absorption side 1212k is not parallel to the atomizing side 1211k, resulting in a porous body 121k having the shape of a trapezoid.

[0052] In Fig. Figure 16 shows a heating arrangement 12m according to some embodiments. The width of a plate heating unit of a heating element 122m is equal to the depth of a receiving groove 1210m; when the plate heating unit of the heating element 122m is received in the receiving groove 1210m in the width direction, an upper surface of the plate heating unit is flush with an atomizing side 1211m. As an alternative solution to the heating arrangement 12 mentioned above, the difference between the heating arrangements 12m and 12 is that a liquid absorption side 1212m is a concave arcuate surface.

[0053] In Fig. Figure 17 shows a heating arrangement 12n according to some embodiments. The heating arrangement 12n is an alternative solution to a heating arrangement 12 mentioned above, and the difference between them is that a porous body 121n of the heating arrangement 12n has three atomizing sides 1211n and three liquid absorption sides 1212n. Each atomizing side 1211n corresponds to a plate heating unit of a heating element 122n, and one width of each atomizing side 1211n is equal to one depth of a corresponding receiving groove 1210n; when the plate heating unit of the heating element 122n is received in the receiving groove 1210n in the width direction, an upper surface of the plate heating unit is flush with the atomizing side 1211n. Each liquid absorption side 1212n is parallel to the corresponding atomizing side 1211n. It is understood that the number of atomizing sides 1211n can be two or more than three.

[0054] In Fig. Figure 18 shows a plate heating unit of a heating element 122p according to some embodiments. The heating element 122p is an alternative solution to the heating element 122 of the heating arrangement 12 mentioned above, and the difference is that the heating element 122p has an elongated plate heating unit in the middle and two electrical connection units 1223p and 1224p, each connected to two ends of the elongated plate heating unit. As shown in Fig. As shown in Figure 18, the elongated plate heating unit, instead of being bent into a specific shape, is formed in the form of a strip. In some embodiments, the plate heating unit is formed integrally with the two electrical connection units 1223p and 1224p, and lower portions of the two electrical connection units 1223p and 1224p each project from a lower edge of the plate heating unit. Thus, when the plate heating unit of the heating element 122p is inserted into a porous body, the electrical connection units 1223p and 1224p can be inserted deeper to engage more firmly with the porous body, preventing the plate heating unit from being dislodged by pulling on the connecting wires. Upper portions of the two electrical connection units 1223p and 1224p each project from an upper edge of the plate heating unit to function as electrical connection wires.

[0055] In Fig. Figure 19 shows a plate heating unit of a heating element 122q according to some embodiments. The plate heating unit of the heating element 122q is shaped as an "S" strip, which has a certain number of parallel flat parts 1221q and a certain number of bent sections 1222q that connect the flat parts 1221q. The plate heating unit of the heating element 122q is an alternative solution to the plate heating unit of the heating element 122 of the heating arrangement 12, and the difference is that the thickness of the bent section 1222q is greater than the thickness of the flat part 1221q, which reduces the resistance of the bent section 1222q and the accumulated heat generated by the bent section 1222q. In some embodiments, the bent section 1222q can be widened to further reduce its resistance.It can be understood that the solution is not limited to the plate heating unit; in other embodiments, a heating coil and a coating plate heating unit are also applicable. According to one embodiment, if the heating coil has the flat part and the bent section, the bent section can be designed to be larger, while in the case of coating heaters, the coating on the bent section can be thicker or wider.

[0056] In Fig. Figure 20 shows a plate heating unit of a heating element 122r according to some embodiments. The plate heating unit of the heating element 122r is an alternative solution to the plate heating unit of the heating element 122, and the difference lies in the fact that the plate heating unit of the heating element 122r has several through-holes 1220r that extend through the thickness direction of the plate heating unit. In the longitudinal direction of the plate heating unit of the heating element 122r, the density of the through-holes in the center of the plate heating unit is higher than that of the through-holes at either end of the plate heating unit. Thus, in the longitudinal direction of the plate heating unit, the resistance of the plate heating unit in the center is greater than the resistances of the plate heating unit at either end, which is able to meet the requirements of the specific heating arrangement and enables the distribution of heat in the porous body to meet the specific needs.

[0057] In Fig. Figure 21 shows a plate heating unit of a heating element 122s according to some embodiments. The plate heating unit of the heating element 122s is an alternative solution to the plate heating unit of the heating element 122, and the difference lies in the fact that the plate heating unit of the heating element has several through holes 1220s extending along its thickness. In the longitudinal direction of the plate heating unit, the density of the through holes in the middle is lower than that of the through holes at both ends of the plate heating unit. Thus, in the longitudinal direction of the plate heating unit, the resistance of the plate heating unit in the middle is lower than that of the plate heating unit at both ends, in order to meet the requirements of the specific heating arrangement.

[0058] In Fig. Figure 22 shows a plate heating unit of a heating element 122t according to some embodiments. As an alternative solution for the plate heating unit of the heating element 122, the difference between the heating elements 122 and 122t lies in the fact that the plate heating unit of the heating element 122t has several through holes 1220t running through its thickness direction, and the density of the through holes 1220t changes gradually (e.g., gradually increases or gradually decreases) or changes in a graduated manner in the width direction of the plate heating unit. Thus, the resistance of the plate heating unit of the heating element 122t changes gradually or in a graduated manner in the width direction of the plate heating unit to meet the requirements of different heating arrangements.

[0059] In Fig. Figure 23 shows a plate heating unit of a heating element 122u according to some embodiments. As an alternative solution for the plate heating unit of the heating element 122, the difference between the heating elements 122u and 122 lies in the fact that the plate heating unit of the heating element 122u is a heating mesh with many meshes 1220u, and the distribution of the meshes 1220u in the longitudinal direction of the plate heating unit can be one of the following.In a first type, the meshes are evenly distributed, resulting in a uniform resistance along the longitudinal direction of the heating element; in a second type, the mesh density in the center of the heating element is lower than that at either end, and the mesh density changes gradually or in steps; in a third type, the mesh density in the center of the heating element is higher than that at either end, and the mesh density changes gradually or in steps. In the transverse direction of the heating element 122u, the meshes 1220u can be evenly distributed; or the meshes at one end can be denser than those at the other end, and the mesh density changes gradually or in steps.

[0060] In Fig. 24 and Fig. Figure 25 shows a heating arrangement 12v according to some embodiments. The heating arrangement 12v has a porous body 121v and a plate heating unit of a heating element 122v arranged in the porous body 121v. As an alternative solution to the heating arrangement 12, the difference between the heating arrangements 12v and 12 lies in the fact that a liquid absorption side of the porous body 121v of the heating arrangement 12v is recessed to form a groove 120v, resulting in the entire porous body 121v having the shape of a bowl. An inner surface of a bottom wall of the porous body 121v forms a liquid absorption side 1212v, while an outer surface of the bottom wall of the porous body 121v forms an atomizing side 1211v. The plate heating unit of the heating element 122v is embedded on the atomizing side 1211v.Since the porous body 121v has a shell-like shape, the entire porous body 121v is tall enough to facilitate the installation of the heating element 12v and the sealing sleeve 115. Furthermore, the distance between the liquid absorption side 1212v and the atomization side 1211v is close enough for easy assembly and improved atomization. The heating element 122v can be any of the heating elements mentioned above.

[0061] In Fig. 26 and Fig. Figure 27 shows an electronic cigarette according to some embodiments. The in Fig. 24 and Fig. The heating arrangement shown in Figure 25 is adopted in the electronic cigarette. It can be understood that any of the heating arrangements mentioned above can be adapted to the electronic cigarette. In some embodiments, the electronic cigarette can be flat, comprising an atomizer 1 and a battery assembly 2, which is detachably connected to the atomizer 1. The atomizer 1 is used to hold e-liquid to produce vapor. The battery assembly 2 is designed to supply the atomizer 1 with electricity. As shown, a lower part of the atomizer 1 is inserted into an upper part of the battery assembly 2; in some embodiments, the atomizer 1 and the battery assembly 2 can be coupled to each other by magnets.

[0062] As in Fig. As shown in Figure 28, in some embodiments the atomizer 1 can have an atomizing assembly 10 and a liquid reservoir 20 that is slid onto the atomizing assembly 10. The atomizing assembly 10 can be used to heat and atomize the e-liquid, while the liquid reservoir 20 is used to store the e-liquid for the atomizing assembly 10.

[0063] As in Fig. 29 to Fig. As shown in Figure 32, the atomizing assembly 10 comprises a lower holder 11, the heating assembly 12v mounted on the lower holder 11, a sealing sleeve 13 slid onto the heating assembly 12v, an upper holder 14 mounted on the lower holder 11 and bearing against the sealing sleeve 13, and a sleeve cover 15 slid onto the upper holder 14. Once the upper holder 14 bears against the sealing sleeve 13, the heating assembly 12v is firmly clamped between the lower holder 11 and the upper holder 14. The sealing sleeve 13 seals the heating assembly 12v and the upper holder 14 to prevent e-liquid leakage and secures the heating assembly 12v horizontally.

[0064] In some embodiments, the lower holder 11 has a base 111, a first support arm 112 mounted on an upper surface of the base 111, and a second support arm 113, also mounted on the upper surface of the base 111 and corresponding to the first support arm 112. The heating arrangement 12v is located between the first support arm 112 and the second support arm 113. The atomizing side 1211v faces directly towards the base 111 and is spaced from the base at a distance that forms the atomizing cavity 110, allowing the smoke to mix with the air.

[0065] In some embodiments, the base 111 can be a rectangular plate. One lower side of the base 111 is recessed to form two receiving grooves 1110 for receiving two magnetic assemblies 16, which are used to magnetize the atomizer 1 and the battery assembly 2 together. First hooks 1112 are formed on opposite end faces of the base 111 for clamping onto the liquid reservoir 20. Two electrode columns 1114, which are electrically connected to the heating assembly 12v, can be formed on one side of the base 111. The two electrode columns 1114 are each electrically connected to the positive and negative poles of the battery assembly 2.

[0066] In some embodiments, the first support arm 112 and the second support arm 113 can be plate-shaped. The inner surfaces of the first support arm 112 and the second support arm 113 are each recessed to form receiving grooves 1122, 1132 for receiving an embedded section 142 of the upper holder 14. The receiving grooves 1122, 1132 are each formed in the upper sections of the first support arm 112 and the second support arm 113. The receiving grooves 1122, 1132 each form steps 1126, 1136 on the first support arm 112 and the second support arm 113. Two ends of the heating arrangement 12v are each held by the steps 1126, 1136. Two clamping sections 1124 and 1134, which are used to clamp to the upper holder 14, are each arranged on the outside sides of the upper ends of the first support arm 112 and the second support arm 113.In some embodiments, the first support arm 112 and the second support arm 113 are arranged symmetrically to facilitate their assembly; more precisely, it is not necessary to distinguish which support arm is the right and which support arm is the left during the assembly of the support arms 112, 113.

[0067] In some embodiments, the lower holder 11 may also have a U-shaped inlet groove structure 114 and a U-shaped outlet groove structure 115, each connected to the outer surfaces of the first support arm 112 and the second support arm 113, respectively, and extending horizontally outwards. A through-hole 1120, which connects the inlet groove structure 114 to the atomizing cavity 110, is formed in the first support arm 112, and a through-hole 1120, which connects the outlet groove structure 115 to the atomizing cavity 110, is formed in the second support arm 113. The through-holes 1120 and 1130 are able to direct air into the atomizing cavity 110 and to discharge the smoke from the atomizing cavity 110. The through holes 1120 and 1130 are each located below the receiving grooves 1122 and 1132.

[0068] In some embodiments, the upper holder 14 may have a main body 141, which is essentially cuboid, an annular embedded section 142 extending from the center of a lower surface of the main body 141, and a second inlet channel 143 extending downward from the right end of the lower surface of the main body 141. The embedded section 142 is received in the receiving grooves 1122 and 1132 between the first support arm 112 and the second support arm 113 of the lower holder 111 and is slid onto the sealing sleeve 13. The upper holder 14 also has two fluid channels 144, a slotted channel 145, and a second outlet channel 146. The fluid channels 144 extend from the upper surface to the lower surface of the main body 141.The slotted channel 145 is formed on a side wall of the main body 141, surrounds the right fluid channel 144, and communicates with the second inlet channel 143. The second outlet channel 146 runs through the center of the upper surface of the upper holder 14 to communicate with the slotted channel 145. The left end of the upper surface of the upper holder 14 is recessed to form two positioning holes 147, which interact with the sleeve cover 15 to perform the positioning and fault-prevention functions. The upper holder 14 also has a second hook 148 that extends downwards to engage with the lower holder 11.

[0069] In some embodiments, the sleeve cover 15 can be made of silicone and may have an upper wall 151, a first annular locking arm 152 extending downwards from one circumference of the upper wall 151, and two second U-shaped locking arms 153 and 154 extending downwards from two ends of the first locking arm 152. Two liquid inlets 155 and a sleeve cover outlet channel 156 are formed on the upper wall 151.

[0070] The two fluid inlets 155 each correspond to the two fluid channels 144 of the upper holder 14. The sleeve cover outlet channel 156 is inserted into and connected to the second outlet channel 146. The first locking arm 152 is used to enclose the side wall of the main body 141 and cover the slot channel 145 on the side wall to form an airtight annular connecting channel in the upper holder 14. The second locking arms 153 and 154 each cover the inlet groove structure 1114 and the outlet groove structure 1115 on the lower holder 11 to form a first airtight inlet channel and a first airtight outlet channel, respectively, which interact with the first support arm 112 and the second support arm 113.A first air inlet 157, connected to the outside environment, is formed on the second locking arm 153, allowing air to be directed through the first air inlet 157 into the first inlet channel. The first outlet channel is connected to the second inlet channel 143. Two positioning columns 158 extend downwards from the left end of the lower surface of the upper wall 151 of the sleeve cover 15. The two positioning columns 158 each interact with the two positioning holes 147 in the upper holder 14, allowing the first air inlet 157 to be precisely positioned on the left side of the arrangement of the upper holder 14 and the lower holder 11, and enabling the first air inlet 157 to communicate with the first inlet channel to fulfill the fault protection function.

[0071] The liquid reservoir 20 has a shell 21 with an air outlet 210 and an airflow tube 22, which is arranged in the shell 21 and is connected to the air outlet 210. The shell 21 has a liquid storage unit 211 and a sleeve section 212, which is connected to the liquid storage unit 211. The liquid storage cavity 23 is formed between the liquid storage unit 211 and the airflow tube 22. The liquid storage cavity 23 has a liquid outlet 230, and the sleeve section 212 is pushed onto a circumference of the liquid outlet 230 so that the sleeve section 212 can be firmly pushed onto the atomizing assembly 10. A step 213 is formed between an inner surface of the sleeve section 212 and an inner surface of the liquid storage unit 211. Stage 213 is located on the upper surface of the atomizing arrangement 10.In some embodiments, the sleeve section 212 is formed integrally with the liquid storage unit 211. The air outlet 210 can be designed as a suction nozzle in the form of a flat trumpet.

[0072] The airflow tube 22 extends from the air outlet 210 towards the liquid outlet 230, and a distal end of the airflow tube 22 extends into the sleeve section 212 and is inserted into the air outlet 210 of the sleeve cover 15, so that the airflow tube 22 is connected to the second outlet channel 146. Second air inlets 2120 are formed in the left and right sides of the sleeve section 212, with the left second air inlet 212 connecting to the first air inlet 157 in the sleeve cover 15 to direct air from outside the sleeve 21 into the first inlet channel formed by the sleeve cover 15 and the lower support 11. According to one embodiment, the sleeve 21 is symmetrically formed for ease of assembly.This is because, if the sleeve 21 forms only a second air inlet 2120 on one side of the sleeve section 212, a step to assess whether the second air inlet 2120 is on the same side as the first air inlet 157 would be required when the sleeve 21 is fitted. Clamping slots 2122 are formed in the inner walls of the left and right sides of the sleeve section 212 to engage with the first hooks 1112 of the lower holder 11, thus facilitating the fastening of the sleeve 21 and the lower holder 11.

[0073] The assembly of atomizer 1 can be carried out using the following steps: Step a, sliding the sealing sleeve 13 onto the heating assembly 12v; Step b, inserting the combination of the sealing sleeve 13 and the heating arrangement 12v into the embedded section 142 of the upper holder 14; Step c, covering the upper holder 14 on the lower holder 11 so that the second hook 148 of the heating arrangement 12v of the upper holder 14 can be clamped onto the clamping sections 1124 and 1134 of the lower holder 11 and thus the upper holder 14 can be clamped onto the lower holder 11, and electrically connecting electrode leads of the heating arrangement 12v to the electrode column 1114 on the lower holder 11; Step d, sliding the sleeve cover 15 onto the upper holder 14 to complete the assembly of the atomizing assembly 10; and Step e, inserting the liquid reservoir 20 with the e-liquid into the sleeve section 212, so that an upper surface of the liquid reservoir 20 rests against the stage 213 to block the liquid outlet 230 of the liquid storage cavity 23, and clamping the first hook 1112 of the lower holder 11 into the clamping slot 2111 of the sleeve section 212 to complete the simple and quick assembly of the atomizer 1.

[0074] As a result, as indicated by the arrow in Fig. In the flow path shown in Figure 32, the air first flows through the second air inlet 2120 and the first air inlet 157 into the first inlet channel and then through the through-hole 1120 into the atomizing cavity 110 to mix with the smoke. The smoke-air mixture flows through the through-hole 1130 into the first outlet channel and then into the second inlet channel 143. The smoke-air mixture then flows successively into the annular connecting channel, the second outlet channel 1466, and the airflow tube 22, and is finally released from the atomizer 1 through the air outlet 210. The e-liquid in the liquid storage cavity 23 flows sequentially through the liquid inlet 155 of the sleeve cover 15 and the liquid channel 144 of the upper holder 14 and then flows into the groove 120 of the heating arrangement 12v to come into contact with the liquid absorption side 1212v to realize the supply of the e-liquid.

[0075] In some embodiments, the position of the second air inlet 2120 is higher than that of the atomizing cavity 110, which better prevents e-liquid from leaking out of the second air inlet 2120 during normal use. The entire base of the airflow tube of the atomizer 1 is essentially U-shaped. The direction of the airflow at the atomizing cavity 110 is parallel to the atomizing side 1211v of the heating assembly 12v, which makes it easier to vent the vapor atomized by the atomizing side 1211v.

[0076] In some embodiments, a groove is formed in the upper surface of the porous body 121v of the heating arrangement 12v. After the e-liquid flows into the groove, the fluid delivery efficiency can be improved. According to one embodiment, the groove increases the contact area between the porous body and the e-liquid; furthermore, the distance between the bottom of the groove and the outer surface of the bottom of the porous body 121v can be very small, which reduces the flow resistance for the e-liquid to reach the outer surface of the bottom of the porous body 121v. Furthermore, since the sealing sleeve 13 is arranged on a liquid supply side of the heating element 122v to seal the e-liquid and prevent the e-liquid from flowing into the atomizing cavity 110, the porous body 121v generally has a certain height to allow the arrangement of the sealing sleeve 13 and the strict requirements of the porous body 121v.The aforementioned groove can not only meet the thickness requirements of the porous ceramic, but also the needs for fluid supply efficiency.

[0077] It can be understood that other suitable heating arrangements can be used to replace the 12V heating arrangement of the aforementioned electronic cigarette. The heating unit of the 12V heating element is not limited to having the form of an elongated plate; in other embodiments, the heating unit of the 12V heating element can have other shapes, such as a strip.

[0078] In Fig. Figure 33 shows a heating arrangement 12w according to some embodiments. As an alternative solution to the heating arrangement 12 mentioned above, the difference between the heating arrangements 12 and 12w lies in the fact that a porous body 121w of the heating arrangement 12w has a corrugated atomizing surface 1211w, and flat parts 1221w of the plate heating unit of a heating element 122w are arranged corresponding to valleys of the corrugated atomizing surface 1211w and are perpendicular to a plane in which the corrugated atomizing surface 1211w is arranged, thereby reducing the drying out of the heating arrangement 122w by the e-liquid accumulating in the valleys of the corrugated atomizing surface 1211w.

[0079] In Fig. Figure 34 shows a heating arrangement 12x according to some embodiments. The width of the plate heating unit of a heating element 122x of the heating arrangement 12x is less than the depth of a receiving groove 1210x. Therefore, when the plate heating unit of the heating element 122x is received in the receiving groove 1210x in the width direction, the upper surface of the plate heating unit is lower than an atomizing side 1211x of the heating arrangement 12x. As an alternative solution to the heating arrangement 12a mentioned above, the difference between the heating arrangements 12a and 12x is that an enclosed angle is formed between the width direction of the plate heating unit of the heating element 122x of the heating arrangement 12x and a normal direction of the atomizing side 1211x. According to one embodiment, the angle can be less than 20 degrees.

[0080] In Fig. Figure 35 shows a heating element 122y according to some embodiments. The heating element 122y has a strip-shaped heating unit in the center and two electrical connection units 1223y and 1224y, each integrally connected to two ends of the heating unit. As an alternative solution to the heating element 122p mentioned above, the difference between the heating elements 122y and 122p lies in the fact that many through holes or blind holes 1220y are formed in a region of the plate heating unit adjacent to an atomizing side of a porous body in order to improve the resistance of the region.

[0081] In Fig.Figure 36 shows a heating element 122z according to some embodiments. The heating element 122z has an elongated plate heating unit in the middle and two electrical connection units 1223z and 1224z, each integrally connected to two ends of the heating unit. As an alternative solution to the heating element 122p mentioned above, the difference between the heating elements 122z and 122p lies in the fact that many through holes or blind holes 1220z are formed in a region of the heating unit of the heating element 122z that is away from an atomizing side of a porous body in order to improve the resistance of the region.

[0082] It can be understood that, although the alternative solutions of the heating element and the porous body in the embodiments mentioned above mainly explain the difference from those in the embodiments mentioned previously, they can be mutually interchangeable if they are not contradictory. For example, the heating element in each embodiment mentioned above can interact with the porous body in each embodiment, and each heating arrangement mentioned above can be used in the electronic cigarette. The above are only the embodiments of the present disclosure, which are not intended to limit the scope of the utility model of the present disclosure.Any equivalent structure or equivalent transformation of the process that has been carried out using the description and accompanying images of the present disclosure, or the direct or indirect use of the description and accompanying images of the present disclosure in other relevant technical fields, is included within the scope of protection of the present disclosure.
