CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This disclosure is based on and claims priority to U.S. Provisional Patent Application No. 63 / 304,624, filed January 30, 2022, and further claims priority to Chinese Patent Application No. 202210296451.9 and Utility Model Registration No. 202220659265.2, filed March 24, 2022, and Chinese Patent Application No. 202210499959.9 and Utility Model Registration No. 202221099745.4, filed May 9, 2022. The entire contents of the above applications are incorporated herein by reference. [Technical field]

[0002] The present invention relates to the field of electronic atomization technology, and in particular to a heating assembly, an atomizer, and an electronic cigarette having the atomizer. [Background technology]

[0003] The atomizer is the core part of the electronic atomization product, and the reliability of the atomizer's quality determines the quality of the entire atomization product.

[0004] In the conventional atomization structure, the surface of the ceramic porous material is covered by printing a heated slurry, or a metal resistance heating element is embedded in the surface. In both of these methods, the porous ceramic is used as an oil-conductive material, and the smoke oil is adsorbed on the surface of the resistance heating element, and when the resistance heating element is energized, heat is generated to atomize the smoke oil. As for the atomization structure of these types, the ceramic molding process is complicated, the yield rate is low, and the conformity of the ceramic is poor, which increases the cost of the product, and the oil conductivity of the ceramic is rather poor, which is prone to defects such as a burnt smell and a slightly poor mouthfeel.

[0005] Another conventional atomizing structure has a spiral resistance heating thread wound around the surface of a horizontal cotton core, and the horizontal cotton core adsorbs smoke oil on the surface of the resistance heating thread, and when the resistance heating thread is energized, heat is generated to atomize the smoke oil. The horizontal cotton core of this atomizing structure is very easy to deform, so it is difficult to assemble, and the oil conduction distance is long, so it is easy to produce a burnt smell.

[0006] Another conventional atomization structure is that the outer surface of the vertical cotton core resistance heating element is wrapped with oil guide cotton, and the inside of the resistance heating element is hollow. The oil guide cotton wrapped on the outer surface adsorbs the smoke oil onto the surface of the resistance heating element, and when the resistance heating thread is energized, heat is generated to atomize the smoke oil. The vertical cotton core of this type is composed of many parts and is complicated to assemble, which makes the product cost high.

[0007] As described above, none of the existing atomization structures can meet the requirements for product quality stability and automated production. Summary of the Invention

[0008] In view of the above, an objective of the present disclosure is to provide a heating assembly and atomizer with high quality stability and capable of automated production and assembly, to at least partially address the problems of poor product quality consistency, difficult assembly, and high cost.

[0009] An embodiment of the present invention provides a heating assembly for use in an atomizer, the heating assembly including a resistive heating element and an atomizing bracket, the resistive heating element coupled to the atomizing bracket and including a first connecting portion, a second connecting portion, and a heating fence, the first connecting portion and the second connecting portion being connected to each other via the heating fence, and the atomizing bracket including an atomizing opening communicating with the heating fence.

[0010] An embodiment of the present invention further provides an atomizer, the atomizer including an atomizing bracket, a resistive heating element and an oil guide member, the resistive heating element is coupled with the atomizing bracket and includes a first connection, a second connection and a heating fence, the first connection and the second connection are connected to each other through the heating fence, the atomizing bracket includes an atomizing opening communicating with the heating fence, the resistive heating element includes a first surface facing the oil guide member and a second surface away from the oil guide member, the oil guide member includes a third surface facing the resistive heating element and a fourth surface away from the resistive heating element, the oil guide member is disposed on the resistive heating element, and the third surface of the oil guide member is in contact with the first surface of the resistive heating element.

[0011] An embodiment of the present invention also provides an electronic cigarette comprising the atomizer described above. Effect of the Invention

[0012] In the heating assembly and atomizer provided by the embodiment of the present invention, the resistance heating element is combined with the atomizing bracket to form a heating assembly. Such a heating assembly can be easily assembled, and can realize automated assembly and production, effectively improving production efficiency and product stability, and effectively ensuring the quality consistency of the atomizing structure. At the same time, the oil guide member is in full and close contact with the resistance heating element in the heating assembly, effectively improving the atomization effect, and avoiding the generation of burnt odor during the atomization process from affecting the taste of smoking.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Hereinafter, the technical aspects of the embodiments of the present disclosure will be clearly and completely described with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, and are not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present invention.

[0015] It should be noted that, in this specification, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply that any actual relationship or ordering exists between those entities or operations.

[0016] [First embodiment] 1 to 6, the atomizer 100 according to the first embodiment of the present invention includes an oil reservoir 110, an atomizing bracket 120, a resistance heating element 130, and an oil guide member 140. Here, the atomizing bracket 120, the resistance heating element 130, and the oil guide member 140 are accommodated in the oil reservoir 110.

[0017] As shown in FIG. 7 to FIG. 11, the resistive heating element 130 is coupled with the atomizing bracket 120, and the oil guide member 140 is installed on the resistive heating element 130. The resistive heating element 130 has a sheet-like structure and is made of a metal sheet. The resistive heating element 130 includes a first connecting portion 134A, a second connecting portion 134B, a heating fence 135, a first surface 131 facing the oil guide member 140, and a second surface 132 away from the oil guide member 140. The first surface 131 is the upper surface of the resistive heating element 130, and the second surface 132 is the lower surface of the resistive heating element 130. The atomizing bracket 120 includes an atomizing opening 126 communicating with the heating fence 135. The oil guide member 140 includes a third surface 143 facing the resistive heating element 130, and a fourth surface 144 away from the resistive heating element 130. Here, the third surface 143 is the lower surface of the oil guide member 140, and the fourth surface 144 is the upper surface of the oil guide member 140. The third surface 143 of the oil guide member 140 is bonded to and in contact with the first surface 131 of the resistive heating element 130.

[0018] In this embodiment, the resistance heating element 130 is combined with the atomization bracket 120, and then the oil guide member 140 is directly laminated and contacted with the resistance heating element 130. This simplifies assembly, realizes automated assembly and production, effectively improves production efficiency and product stability, and effectively ensures the consistency of the quality of the atomization structure. In addition, the resistance heating element 130 is in full and close contact with the oil guide member 140, effectively improving the atomization effect and preventing the generation of a burnt smell during atomization to affect the taste of smoking.

[0019] As shown in FIG. 7 to FIG. 11, specifically, the first surface 131 and the second surface 132 of the resistance heating element 130 are both flat surfaces and parallel to each other. The oil guide member 140 has a block structure. The third surface 143 and the fourth surface 144 of the oil guide member 140 are both flat surfaces and parallel to each other. The oil guide member 140 can uniformly absorb the smoke oil and transport it to the resistance heating element 130 to further enhance the atomization effect. The oil guide member 140 can be oil guide cotton.

[0020] The resistive heating element 130 has a plurality of through holes 133 hollowed out in the center, forming a heating fence 135. As a result, the resistive heating element 130 forms a first connecting portion 134A, a second connecting portion 134B, and a heating fence 135. The first connecting portion 134A, the second connecting portion 134B, and the heating fence 135 are located in the same plane. The heating fence 135 is located in the middle of the resistive heating element 130. The first connecting portion 134A and the second connecting portion 134B are located on two opposite sides of the heating fence 135 along the longitudinal direction of the resistive heating element 130, respectively. Therefore, the heating fence 135 is located between the first connecting portion 134A and the second connecting portion 134B, and the first connecting portion 134A and the second connecting portion 134B are connected to each other by the heating fence 135. The heating fence 135 forms a plurality of resistive heating wires 1351 between adjacent through-holes 133, so that the heating fence 135 is the heating portion of the resistive heating element 130. The smoke generated by atomization passes through these through-holes 133 and enters the airflow passage in the atomizer 100, where it is carried away by the external gas that enters the atomizer, and is inhaled by the user.

[0021] The resistive heating element 130 further includes first and second conductive pins 136A, 136B respectively connected to the first connection portion 134A and the second connection portion 134B, and each conductive pin 136A, 136B is electrically connected to the corresponding connection portion 134A, 134B. In this embodiment, each conductive pin 136A, 136B is an elongated plate, and each conductive pin 136A, 136B is connected to the corresponding connection portion 134A, 134B via a curved portion 139. Each conductive pin 136A, 136B and the corresponding connection portion 134A, 134B are separated from each other by the atomizing bracket 120. Each conductive pin 136A, 136B is located on the lower surface of the atomizing bracket 120 and is exposed to the outside of the atomizing bracket 120. In addition, each conductive pin 136A and 136B is in contact with the lower surface of the atomizing bracket 120.

[0022] In this embodiment, each of the conductive pins 136A, 136B extends from two opposing ends of the resistance heating element 130 to the outside of the atomizing bracket 120 and is curved downward and inward. Specifically, each of the conductive pins 136A, 136B is curved downward and inward from the two connecting portions 134A, 134B, respectively. Each of the conductive pins 136A, 136B is exposed on the lower surface of the atomizing bracket 120. This makes it easy to electrically connect the exposed conductive pins 136A, 136B to the conductive electrode 175 (see FIG. 5).

[0023] The resistive heating element 130 is made of metal, for example, the material of the resistive heating element 130 may be nickel-chromium alloy, iron-chromium-aluminum, S316L stainless steel or other alloy materials. The atomizing bracket 120 is made of a thermoplastic material that has a high thermal decomposition temperature and can withstand rapid temperature changes, for example, plastic, rubber, or silicone resin. The resistive heating element 130 is combined with the atomizing bracket 120 by insert molding. Specifically, when manufacturing the atomizing bracket 120, the resistive heating element 130 is placed into a cavity of a mold (not shown), molten plastic, rubber or silicone resin is injected into the cavity of the mold, the molten plastic, rubber or silicone resin is applied to the outer periphery of the resistive heating element 130, and after cooling, the atomizing bracket 120 is formed, the resistive heating element 130 is at least partially fitted into the atomizing bracket 120, and the bottom surface and outer edge of the first connecting portion 134A and the second connecting portion 134B, as well as the outer edge of the heating fence 135 are integrated with the atomizing bracket 120.

[0024] As shown in FIG. 10 and FIG. 11, after the resistive heating element 130 is embedded in the atomizing bracket 120 by insert injection, both ends of the resistive heating element 130 extend horizontally outside the atomizing bracket 120 (see FIG. 10). Next, both ends of the resistive heating element 130 are bent downward and inward using a tool (not shown) to form two conductive pins 136A, 136B (see FIG. 11). The first conductive pin 136A and the second conductive pin 136B are respectively connected to the first connecting portion 134A and the second connecting portion 134B via a curved portion 139, and are respectively located below the first connecting portion 134A and the second connecting portion 134B. In addition, the two conductive pins 136A, 136B are exposed to the outside of the atomizing bracket 120. Specifically, each conductive pin 136A, 136B is attached to and contacts the lower surface of the bottom plate 121 of the atomizing bracket 120.

[0025] The resistive heating element 130 is combined with the atomizing bracket 120 to form a heating assembly.

[0026] As shown in FIG. 7 to FIG. 11, the atomizing bracket 120 includes a bottom plate 121 and a side wall 122 formed by extending upward from the periphery of the bottom plate 121. A receiving cavity 123 is formed in the atomizing bracket 120, and the receiving cavity 123 is surrounded by the bottom plate 121 and the side wall 122 of the atomizing bracket 120, and an opening 123A is formed at the upper end of the receiving cavity 123. The atomizing opening 126 is provided in the middle of the bottom plate 121 and penetrates the upper and lower surfaces of the bottom plate 121. The atomizing opening 126 communicates with the heating fence 135. That is, the heating fence 135 is provided at a position corresponding to the atomizing opening 126 and is aligned vertically with the atomizing opening 126. The atomization opening 126 communicates with the receiving cavity 123 , and the heating fence 135 is exposed and positioned above the atomization opening 126 , and the heating fence 135 spans over the atomization opening 126 .

[0027] In this embodiment, the size of the mist opening 126 is much smaller than the bottom plate 121, so that the surface area of ​​the heated fence 135 exposed in the receiving cavity 123 is larger than the other surface area exposed in the mist opening 126. Alternatively, the surface area of ​​the heated fence 135 for contacting the oil guide member 140 is larger than the other surface area of ​​the heated fence 135 facing the mist opening 126.

[0028] As shown in FIGS. 9 and 11, the second surface 132 of the resistive heating element 130 is higher than the lower surface of the bottom plate 121 of the atomizing bracket 120, and a certain distance, preferably 0.5 mm to 2.0 mm, is formed between them.

[0029] The outer contour of the oil guide member 140 matches the shape of the receiving cavity 123, and the oil guide member 140 is disposed in the receiving cavity 123 through the opening 123A at the upper end of the receiving cavity 123. The oil guide member 140 is disposed flat in the receiving cavity 123 of the atomizing bracket 120. The oil guide member 140 is disposed independently of the atomizing bracket 120 and the resistance heating element 130, and is separably accommodated in the receiving cavity 123. That is, the oil guide member 140 can be accommodated in the receiving cavity 123 or can be removed from the receiving cavity 123. The oil guide member 140 has an oil adsorption ability, but the atomizing bracket 120 does not have an ability to adsorb oil. The atomizing bracket 120 is combined with the resistance heating element 130 and is used to accommodate and support the oil guide member 140. By constraining the oil guide member 140 within the receiving cavity 123, the fume oil absorbed by the oil guide member 140 into the receiving cavity 123 can only be supplied to the resistance heating element 130 for atomization, which can effectively prevent the fume oil from leaking and scattering during atomization.

[0030] As shown in FIG. 7 and FIG. 11, the bottom plate 121 of the atomizing bracket 120 includes a support surface 124 that is bonded to and in contact with the third surface 143 of the oil guide member 140. Specifically, the support surface 124 is the upper surface of the bottom plate 121. The first surface 131 of the resistance heating element 130 is flush with the upper surface of the bottom plate 121, that is, the upper surface of the heating fence 135 and the upper surfaces of each connecting portion 134A, 134B are located in the same plane as the upper surface of the bottom plate 121. The first surface 131 of the resistance heating element 130 is exposed outside the bottom plate 121 of the atomizing bracket 120. That is, the upper surfaces of each connecting portion 134A, 134B and the upper surface of the heating fence 135 are exposed outside the bottom plate 121 of the atomizing bracket 120. When the oil guide member 140 is disposed in the receiving cavity 123, the third surface 143 of the oil guide member 140 is in close contact with the first surface 131 of the resistance heating element 130 and the upper surface of the bottom plate 121 (i.e., the support surface 124), so that the oil guide member 140 is placed flat in the receiving cavity 123 of the atomizing bracket 120. Specifically, the third surface 143 of the oil guide member 140 is in contact with the upper surface of the heating fence 135, the upper surfaces of the connecting parts 134A and 134B of the resistance heating element 130, and the upper surface of the bottom plate 121 (i.e., the support surface 124).

[0031] As shown in FIG. 11, each of the conductive pins 136A, 136B is attached to and in contact with the lower surface of the bottom plate 121, each of the connection parts 134A, 134B is located on the upper surface of the bottom plate 121, and each of the connection parts 134A, 134B is located above the corresponding conductive pins 136A, 136B. Each of the connection parts 134A, 134B and the corresponding conductive pins 136A, 136B are arranged facing the upper surface and the lower surface of the bottom plate 121. Each of the connection parts 134A, 134B and the corresponding conductive pins 136A, 136B are separated via the bottom plate 121 of the atomization bracket 120. Also, each of the connection parts 134A, 134B and the corresponding conductive pins 136A, 136B are connected via a curved part 139. The connecting portions 134A, 134B, the heating fence 135, the conductive pins 136A, 136B and the curved portion 139 are of unitary construction.

[0032] 8 and 11, when the oil guide member 140 is completely accommodated in the receiving cavity 123, the fourth surface 144 of the oil guide member 140 is lower than the upper surface of the side wall 122 of the atomizing bracket 120. This forms a hollow chamber (cavity) 123B in the atomizing bracket 120. The hollow chamber 123B is surrounded by the fourth surface 144 of the oil guide member 140 and the side wall 122 of the atomizing bracket 120.

[0033] As shown in Figures 2, 3, 5 and 6, the atomizer 100 further includes an oil guide bracket 150 accommodated in the oil reservoir 110. The oil guide bracket 150 is installed above the atomizing bracket 120. The bottom end of the oil guide bracket 150 is provided with an annular pressing wall 151, which extends into the hollow chamber 123B and abuts against the outer periphery of the fourth surface 144 of the oil guide member 140. The pressing wall 151 applies a downward pressing force to the oil guide member 140, so that the oil guide member 140 is sandwiched between the pressing wall 151 and the bottom plate 121 of the atomizing bracket 120, which can prevent the oil guide member 140 from being loosened and displaced, and the oil guide member 140 can be better in contact with the resistance heating element 130, which can further improve the atomization effect.

[0034] Two baffles 152 are provided facing each other at the bottom end of the oil guide bracket 150. The pressing wall 151 is located between the two baffles 152. A gap 153 is formed between the pressing wall 151 and the two baffles 152. The side wall 122 of the atomizing bracket 120 is inserted into the gap 153. By restricting the side wall 122 of the atomizing bracket 120 within the gap 153, the atomizing bracket 120 can be stably attached within the atomizer 100.

[0035] In the gap 153, a seal pad 181 is provided, which is sandwiched between the upper surface of the side wall 122 of the atomizing bracket 120 and the lower end surface of the oil guide bracket 150. The seal pad 181 has a sheet-like structure, and a through hole (not shown) through which the pressing wall 151 penetrates is provided in the center. The seal pad 181 can prevent the smoke oil adsorbed in the receiving cavity 123 from leaking from the upper surface of the side wall 122.

[0036] The tip of the oil guide bracket 150 has two first liquid injection holes 154 on both sides, and an oil storage chamber 111 is provided in the oil reservoir 110. Each first liquid injection hole 154 connects the oil storage chamber 111 to the oil guide member 140, so that the smoke oil in the oil storage chamber 111 can be transmitted to the oil guide member 140 through the first liquid injection holes 154.

[0037] The tip of the oil guide bracket 150 is provided with a first exhaust hole 155 in the center, and the first exhaust hole 155 is located between the two first liquid injection holes 154. A smoke exhaust passage 112 isolated from the oil storage chamber 111 is provided in the oil reservoir 110, and an exhaust passage 113 (see FIG. 6) is formed between the side wall 122 of the atomizing bracket 120 and the oil reservoir 110. The first exhaust hole 155 connects the smoke exhaust passage 112 and the exhaust passage 113, so that the airflow in the atomizer 100 flows through the exhaust passage 113 and the first exhaust hole 155 to the smoke exhaust passage 112.

[0038] The atomizer 100 further includes a seal cover 160 accommodated in the oil reservoir 110. The seal cover 160 is provided above the oil guide bracket 150. The seal cover 160 is provided with a second exhaust hole 161 in the center, and the second exhaust hole 161 communicates with the smoke exhaust passage 112 and the first exhaust hole 155, so that the airflow in the atomizer 100 can flow to the smoke exhaust passage 112 through the exhaust passage 113, the first exhaust hole 155, and the second exhaust hole 161 in sequence. Two second liquid injection holes 162 corresponding to the two first liquid injection holes 154, respectively, are provided on both sides of the seal cover 160. Each second liquid injection hole 162 connects the oil storage chamber 111 to a corresponding first liquid injection hole 154, so that the smoke oil in the oil storage chamber 111 is transmitted to the oil guide member 140 sequentially via the second liquid injection hole 162 and the first liquid injection hole 154.

[0039] The oil reservoir 110 includes an outer tube 114 and an inner tube 115 located in the outer tube 114. The bottom end of the outer tube 114 is an open end, and the inner tube 115 is connected to the tip of the outer tube 114. The oil storage chamber 111 is formed between the outer tube 114 and the inner tube 115. Specifically, the oil storage chamber 111 is an annular groove provided around the inner tube 115. The smoke exhaust passage 112 is formed inside the inner tube 115, and the exhaust passage 113 is formed between the side wall 122 of the atomizing bracket 120 and the inner wall of the outer tube 114. In this embodiment, the inner tube 115 is integral with the tip of the outer tube 114, that is, the inner tube 115 is integrally molded with the outer tube 114.

[0040] The seal cover 160 has a side wall 163, the oil guide bracket 150 has a side wall 156 at its tip, the side wall 163 of the seal cover 160 is interposed between the side wall 156 at the tip of the oil guide bracket 150 and the inner wall of the outer tube 114, and the bottom end of the inner tube 115 is inserted into the second exhaust hole 161. This brings the outer wall of the bottom end of the inner tube 115 and the seal cover 160 into tight contact, preventing the leakage of smoke oil from the oil storage chamber 111.

[0041] The atomizer 100 further includes an atomizing base 170 disposed below the atomizing bracket 120 and attached to the bottom open end of the outer tube 114. The atomizing base 170 includes a bottom plate 171 and a side wall 172 extending upward from the periphery of the bottom plate 171. The bottom plate 171 of the atomizing base 170 is provided with an air intake hole 173, through which the external air flows into the outer tube 114 and is exhausted together with the smoke generated by the atomization through the exhaust passage 113, the first exhaust hole 155, the second exhaust hole 161 and the smoke exhaust passage 112 in sequence, so that the user can inhale.

[0042] The atomizer 100 further includes a seal ring 182 housed in the oil reservoir 110. The seal ring 182 has an annular structure. The seal ring 182 is sandwiched between the side wall 172 of the atomizing base 170 and the inner wall of the outer tube 114 to prevent smoke oil from leaking from the open end at the lower end of the outer tube 114.

[0043] Two positioning pins 174 are extended upward on the inner surface of the bottom plate 171 of the atomizing base 170. The atomizer 100 further includes two conductive electrodes 175. The two conductive electrodes 175 are inserted into the two positioning pins 174, respectively. Moreover, the tips of the two conductive electrodes 175 are respectively conductive with the two conductive pins 136A, 136B of the resistance heating element 130. The bottom ends of the two conductive electrodes 175 are exposed to the outside of the oil reservoir 110, so that the two conductive electrodes 175 can be conveniently further conductively connected to a power supply (not shown).

[0044] The atomizer 100 further includes an oil absorbing member 183 housed in the oil reservoir 110. The oil absorbing member 183 has a sheet-like structure, is installed on the inner surface of the bottom plate 171 of the atomizing base 170, and is provided so as to enclose the two positioning pins 174. The oil absorbing member 183 can absorb condensed liquid or smoke oil generated during the atomizing operation and prevent the condensed liquid or smoke oil from leaking out. The oil absorbing member 183 is oil absorbing cotton or other material with oil absorbing function.

[0045] 9 to 11, the atomization opening 126 is provided through the center of the bottom plate 121 of the atomization bracket 120, and a heating fence 135 is formed in the center of the resistance heating element 130, and the heating fence 135 is provided corresponding to the atomization opening 126. The smoke generated by atomization enters the airflow passage in the atomizer 100 through the heating fence 135 and the atomization opening 126, and is removed by the external airflow that has entered the atomizer 100, so that the user can inhale it.

[0046] 5, the smoke oil stored in the oil storage chamber 111 of the oil reservoir 110 passes through the second liquid injection hole 162 in the seal cover 160 and the first liquid injection hole 154 in the oil guide bracket 150 to reach the fourth surface 144 of the oil guide member 140, and is absorbed by the oil guide member 140 and transferred onto the third surface 143 in close contact with the resistance heating element 130. During energization, the resistance heating element 130 generates heat, atomizes the smoke oil in contact with the first surface 131 of the resistance heating element 130 to form smoke, and the smoke formed by atomization passes through the heating fence 135 and the atomization opening 126 and enters the cavity of the atomization base 170. As shown by the airflow direction arrows in Figure 6, outside air enters the cavity of the atomization base 170 through the air intake hole 173 in the atomization base 170, and is exhausted through the exhaust passage 113, the first exhaust hole 155, the second exhaust hole 161, and the smoke exhaust passage 112 together with the smoke formed by atomization, allowing the user to inhale.

[0047] In this embodiment, the resistance heating element is combined with the atomizing bracket made of plastic, rubber or silicone resin to form a heating assembly, which can realize automatic molding and production through a mold, and does not need to carry out complicated post-processing according to the requirements of ceramics after molding, effectively improving production efficiency and product stability, and effectively ensuring the quality consistency of the atomizing structure.

[0048] In this embodiment, the sheet-shaped oil guide member is installed in the cavity of the heating assembly, and then the oil guide bracket is installed. When the sheet-shaped oil guide member is subjected to the downward pressing force of the oil guide bracket, it comes into close contact with the resistance heating element of the heating assembly. This forms an atomization structure with heating ability and oil guide channel, effectively improving the atomization effect and avoiding the problem of burnt odor generated during atomization that affects the taste of smoking.

[0049] 12 to 17 show another example of the heating assembly in the first embodiment. The heating assembly 10 includes an atomizing bracket 120 and a resistive heating element 130 at least partially embedded in the atomizing bracket 120. The atomizing bracket 120 includes a bottom plate 121 and a side wall 122 extending upward from the periphery of the bottom plate 121. A receiving cavity 123 is formed between the bottom plate 121 and the side wall 122. An atomizing opening 126 is provided to penetrate the bottom plate 121. A heating fence 135 of the resistive heating element 130 straddles the atomizing opening 126. The upper surface of the heating fence 135 and the upper surface of the bottom plate 121 are located in the same plane. The bottom plate 121 has two inclined portions 1211. The two inclined portions 1211 are located on two opposite sides of the bottom plate 121 along a first direction (for example, the width direction of the atomizing bracket 120). The atomizing opening 126 is located between the two inclined portions 1211. The thickness of each inclined portion 1211 gradually decreases from the side wall 122 to the atomizing opening 126. In this embodiment, the resistive heating element 130 is a metal plate made of, for example, nickel-chromium alloy, iron-chromium-aluminum, S316L stainless steel or other metal or metal alloy material. The atomizing bracket 120 is made of a thermoplastic material with a high pyrolysis temperature and can withstand rapid temperature changes. For example, the atomizing bracket 120 is made of plastic, rubber, or silicone resin. The resistive heating element 130 can be combined with the atomizing bracket 120 by an insert injection molding process.

[0050] In the heating assembly 10, the upper surface of the heating fence 135 and the upper surface of the bottom plate 121 are located in the same plane. When the oil guide member 140 is installed in the receiving cavity 123, the oil guide member 140 contacts the heating fence 135, which avoids the impact of the combustion odor on smoking during the atomization process and effectively improves the atomization effect. The thickness of the inclined portion 1211 gradually decreases from the side wall 122 to the atomization opening 126. During the injection molding process of the inclined portion 1211, the thickness of the inclined portion 1211 on the side close to the atomization opening 126 is small, so that the injection molding material does not flow to the heating fence 135 and does not contaminate the heating fence 135. That is, the edge of the inclined portion 1211 located at the atomization opening 126 does not form a rough edge of the injected material, which can effectively avoid secondary processing (removing the rough edge), which is favorable to improving production efficiency, reducing production costs, and ensuring the high quality and stability of the product.

[0051] 14 and 17, the inclined portion 1211 forms an inclined surface 1212 at the bottom of the bottom plate 121. That is, the inclined portion 1211 has a flat surface at the top and an inclined surface 1212 at the bottom. The inclined surface 1212 is recessed from the lower surface of the bottom plate 121 and inclines upward from the side wall 122 toward the atomizing opening 126. The flat surface at the top of the inclined portion 1211 is a part of the upper surface of the bottom plate 121. The heating fence 135 includes two recessed portions 1352 arranged opposite to each other along the first direction (i.e., the width direction of the atomizing bracket 120). The two recessed portions 1352 are arranged corresponding to the two inclined portions 1211, respectively. The recessed portions 1352 include a plurality of recessed legs 1353 spaced apart from each other. The recessed legs 1353 are at least partially embedded in the atomizing bracket 120.

[0052] 14, the fitting leg 1353 includes a suspension segment 1354, a fourth fitting segment 1355, and a fifth fitting segment 1356. The suspension segment 1354 is disposed corresponding to the atomization opening 126. The lower surface of the fourth fitting segment 1355 is embedded in the inclined portion 1211. The upper surface of the fourth fitting segment 1355 is exposed in the receiving cavity 123. The fifth fitting segment 1356 is embedded in the connection portion between the inclined portion 1211 and the side wall 122.

[0053] 14 and 17, a plurality of through holes 133 are provided in the middle of the heating fence 135. The resistance heating wire 1351 is disposed between two adjacent through holes 133. The resistance heating wire 1351 is connected between two insertion portions 1352 and disposed corresponding to the atomization opening 126. When the heating fence 135 is energized, heat is generated in both the resistance heating wire 1351 and the insertion portion 1352, or heat is generated only in the resistance heating wire 1351.

[0054] Optionally, the heating fence 135 includes a first portion, two second portions, and two third portions arranged along a first direction (i.e., the width direction of the atomizing bracket 120). Here, the first portion is connected between the two second portions, and the two third portions are respectively connected to the two second portions. The first portion corresponds to the atomizing opening 126. The lower surfaces of the two second portions are embedded in the inclined portion 1211, and the upper surfaces of the two second portions are exposed in the receiving cavity 123. The two third portions are embedded in the connection portion between the inclined portion 1211 and the side wall 122. Here, the first portion is provided with a plurality of through holes 133, a resistance heating wire 1351 is provided between two adjacent through holes 133, and a plurality of notches 1350 are provided at both ends of the first portion adjacent to the second portion. The notches 1350 are at least partially located above the atomizing opening 126.

[0055] The minimum thickness of the inclined portion 1211 is 0.1 mm to 2 mm.

[0056] Also, as shown in FIG. 14, FIG. 15 and FIG. 17, the resistance heating element 130 further includes a first connection portion 134A and a second connection portion 134B located opposite each other along a second direction (the longitudinal direction of the atomizing bracket 120). Here, the second direction is perpendicular to the first direction. The first and second connection portions 134A, 134B may be energized to generate heat. The heating fence 135 is connected between the first connection portion 134A and the second connection portion 134B. Each of the first and second connection portions 134A, 134B includes an intermediate segment 1341 and two first engagement segments 1342 arranged along the first direction (i.e., the width direction of the atomizing bracket 120). The intermediate segment 1341 is connected between the two first engagement segments 1342. The lower surface of the middle segment 1341 is embedded in the bottom plate 121 , the upper surface of the middle segment 1341 is exposed in the receiving cavity 123 , and the two first fitting segments 1342 are embedded in the connection sites between the bottom plate 121 and the side walls 122 .

[0057] 14, 15 and 17, the resistive heating element 130 further includes first and second conductive pins 136A, 136B located opposite each other along the second direction (i.e., the longitudinal direction of the atomizing bracket 120). The first conductive pin 136A and the second conductive pin 136B are respectively connected to the first connection portion 134A and the second connection portion 134B. Here, the first connection portion 134A is connected between the heating fence 135 and the first conductive pin 136A, and the second connection portion 134B is connected between the heating fence 135 and the second conductive pin 136B. Each of the first conductive pin 136A and the second conductive pin 136B includes a second recessed segment 1361, a third recessed segment 1362, a curved segment 1363 and an electrode segment 1364. The second fitting segment 1361 is connected to the intermediate segment 1341 of the first connecting portion 134A or the second connecting portion 134B.

The curved segment 1363 and the electrode segment 1364 are arranged outside the atomizing bracket 120, the curved segment 1363 is arranged on the outer circumferential surface of the bottom plate 121, and the electrode segment 1364 is arranged on the lower surface of the bottom plate 121.

[0058] Additionally, the upper surface of the heating fence 135, the first connecting portion 134A, the second connecting portion 134B, the first conductive pin 136A, the second conductive pin 136B, and the bottom plate 121 are located in the same plane. The first conductive pin 136A and the second conductive pin 136B are bent downward and inward to form two electrode segments 1364 that contact the lower surface of the bottom plate 121.

[0059] In this embodiment, the resistance heating element 130 is coupled to the atomization bracket 120, and the oil guide member 140 is accommodated in the atomization bracket 120 and directly contacts the resistance heating element 130. This simplifies the assembly, realizes automated assembly and production, effectively improves the production efficiency and product stability, and effectively ensures the quality consistency of the atomizer. In addition, the resistance heating element 130 is in direct and complete contact with the oil guide member 140, effectively improving the atomization effect and avoiding the burnt smell during atomization from affecting the taste of smoking.

[0060] [Second embodiment] 18 to 21, the atomizer 100 according to the second embodiment of the present invention includes an oil reservoir 110, an atomizing bracket 120, a resistance heating element 130, and an oil guide member 140. Here, the atomizing bracket 120, the resistance heating element 130, and the oil guide member 140 are accommodated in the oil reservoir 110.

[0061] As shown in FIG. 20 to FIG. 25, the resistive heating element 130 is coupled with the atomizing bracket 120, and the oil guide member 140 is installed on the resistive heating element 130. The resistive heating element 130 has a sheet-like structure and is made of a metal sheet. The resistive heating element 130 includes a first connecting portion 134A, a second connecting portion 134B, a heating fence 135, a first surface 131 facing the oil guide member 140, and a second surface 132 away from the oil guide member 140. Here, the first connecting portion 134A and the second connecting portion 134B are connected to each other by the heating fence 135, the first surface 131 is the upper surface of the resistive heating element 130, and the second surface 132 is the lower surface of the resistive heating element 130. The atomizing bracket 120 includes an atomizing opening 126 communicating with the heating fence 135. The oil guide member 140 includes a third surface 143 facing the resistive heating element 130 and a fourth surface 144 facing away from the resistive heating element 130, where the third surface 143 is the lower surface of the oil guide member 140 and the fourth surface 144 is the upper surface of the oil guide member 140. The third surface 143 of the oil guide member 140 is in contact with the first surface 131 of the resistive heating element 130.

[0062] In this embodiment, after the resistive heating element 130 is combined with the atomizing bracket 120, the oil guide member 140 is in direct contact with the resistive heating element 130. In this way, the assembly is simple, automated assembly and production can be realized, the production efficiency and product stability can be effectively improved, and the quality consistency of the atomizing assembly can be effectively ensured. In addition, the resistive heating element 130 is in full and close contact with the oil guide member 140, which effectively improves the atomization effect and prevents the generation of a burnt smell during atomization, which affects the taste of smoking.

[0063] Specifically, as shown in FIGS. 26 and 27, a first surface 131 and a second surface 132 of a resistive heating element 130 are both flat surfaces and are parallel to each other.

[0064] As shown in Figures 18 and 20, the oil guide member 140 has a block structure. The third surface 143 and the fourth surface 144 of the oil guide member 140 are both flat surfaces and parallel to each other. The oil guide member 140 can uniformly absorb the smoke oil and transport it to the resistance heating element 130 to further improve the atomization effect. The oil guide member 140 can be oil guide cotton.

[0065] As shown in Figures 20, 21, 26 and 27, a plurality of through holes 133 for forming a heating fence 135 is provided in the center of the resistance heating element 130, so that the resistance heating element 130 forms a first connecting portion 134A, a second connecting portion 134B and a heating fence 135. The first connecting portion 134A, the second connecting portion 134B and the heating fence 135 are located in the same plane. The heating fence 135 is installed in the center of the resistance heating element 130, and the first connecting portion 134A and the second connecting portion 134B are located on two opposite sides of the heating fence 135 along the longitudinal direction of the resistance heating element 130. Therefore, the heating fence 135 is located between the first connecting portion 134A and the second connecting portion 134B, and the first connecting portion 134A and the second connecting portion 134B are connected to each other by the heating fence 135. The heating fence 135 forms a plurality of resistive heating wires 1351 between adjacent through-holes 133, so that the heating fence 135 is the heating portion of the resistive heating element 130. The smoke generated by atomization enters the airflow passage in the atomizer 100 through these through-holes 133, and is removed by the external airflow that enters the atomizer 100, so that the smoke can be inhaled by the user.

[0066] As shown in FIG. 20 to FIG. 27, the atomizing bracket 120 includes a top plate 128 and a side wall 122 extending downward from the periphery of the top plate 128. The resistive heating element 130 further includes two conductive pins 136 electrically connected to the first connecting portion 134A and the second connecting portion 134B, respectively. In this embodiment, each conductive pin 136 has a shape of an elongated conductor and includes a horizontal portion 1365 and a vertical portion 1366. One end of the horizontal portion 1365 is connected to the corresponding connecting portion 134A, 134B. The vertical portion 1366 is formed by curving and extending downward from the other end of the horizontal portion 1365, and extends downward so as to penetrate the top plate 128. A fitting slot 127 is provided on the upper surface of the atomizing bracket 120, and the horizontal portion 1365 is provided in the fitting slot 127. This allows the resistive heating element 130 to be at least partially fitted within the top plate 128 of the atomizing bracket 120, thereby achieving coupling between the resistive heating element 130 and the atomizing bracket 120. The downwardly curving vertical portion 1366 facilitates electrical connection to a power supply (not shown). In this embodiment, the vertical portion 1366 and the horizontal portion 1365 are perpendicular to each other, forming a 90 degree angle.

[0067] The resistive heating element 130 is made of metal, for example, the material of the resistive heating element 130 may be an alloy material such as nickel-chromium alloy, iron-chromium-aluminum, S316L stainless steel, etc. The atomizing bracket 120 is made of a thermoplastic material that has a high thermal decomposition temperature and can withstand rapid temperature changes. For example, the atomizing bracket 120 can be made of plastic, rubber, or silicone resin. As another bonding method, the resistive heating element 130 is integrally bonded to the atomizing bracket 120 by an insert molding process, so that the first connecting portion 134A, the second connecting portion 134B, and the heating fence 135 are fitted into the atomizing bracket 120. Specifically, when making the atomizing bracket 120, the resistive heating element 130 is placed in a cavity of a mold (not shown), and then molten plastic, rubber, or silicone resin is injected into the cavity of the mold, so that the molten plastic, rubber, or silicone resin is coated on the outer circumference of the resistive heating element 130, and the atomizing bracket 120 is formed after cooling. In this manner, the resistive heating element 130 is at least partially embedded in the atomizing bracket 120 .

[0068] In this embodiment, a resistive heating element 130 is coupled with the atomizing bracket 120 to form a heating assembly.

[0069] As shown in FIG. 20 to FIG. 25, the atomizing bracket 120 includes a top plate 128 and a side wall 122 formed by extending downward from the periphery of the top plate 128. The resistance heating element 130 is embedded in the top plate 128 of the atomizing bracket 120. The first surface 131 of the resistance heating element 130 is flush with the upper surface of the top plate 128 of the atomizing bracket 120. The third surface 143 of the oil guide member 140 is also bonded to and in contact with the upper surface of the top plate 128 of the atomizing bracket 120. The oil guide member 140 is provided independently of the atomizing bracket 120 and the resistance heating element 130. The oil guide member 140 has the ability to absorb smoke oil, but the atomizing bracket 120 does not have the ability to absorb smoke oil. The atomizing bracket 120 is used to combine the resistance heating element 130 and support the oil guide member 140.

[0070] The atomization opening 126 is provided on one side of the top plate 128, and penetrates the top and bottom surfaces of the top plate 128. The atomization opening 126 communicates with the heating fence 135. That is, the heating fence 135 is provided at a position corresponding to the atomization opening 126, and is aligned vertically with the atomization opening 126. The heating fence 135 is exposed and positioned above the atomization opening 126, and spans over the atomization opening 126.

[0071] As shown in FIGS. 20 and 21, the second surface 132 of the resistive heating element 130 is higher than the lower surface of the bottom plate 121 of the atomizing bracket 120, and there is a certain distance therebetween, preferably 0.5 mm to 2.0 mm.

[0072] As shown in Figs. 20 to 25, the top plate 128 of the atomizing bracket 120 includes a support surface 124 that is bonded to and in contact with the third surface 143 of the oil guide member 140. Specifically, the support surface 124 is the upper surface of the top plate 128. The first surface 131 of the resistance heating element 130 is flush with the upper surface of the top plate 128. The third surface 143 of the oil guide member 140 is bonded to and in contact with the first surface 131 of the resistance heating element 130 and the upper surface of the top plate 128 (i.e., the support surface 124), and the oil guide member 140 is installed flat on the upper surface of the top plate 128.

[0073] In another embodiment, the first surface 131 of the resistive heating element 130 may be slightly higher than the upper surface of the top plate 128, so that the oil guide member 140 is pressed by the gravitational force of the oil reservoir 116, and the first surface 131 of the resistive heating element 130 is slightly recessed into the oil guide member 140, thereby improving the contact area between the resistive heating element 130 and the oil guide member 140 and the liquid conduction effect.

[0074] As shown in FIG. 18, FIG. 20 and FIG. 21, an oil reservoir 110 is provided with an oil storage chamber 111, and an oil storage section 116 is provided in the oil storage chamber 111. The oil storage section 116 is hollow cylindrical, its shape matches the oil storage chamber 111, and it is properly accommodated in the oil storage chamber 111. The oil storage chamber 111 is completely occupied by the oil storage section 116. The bottom surface of the oil storage section 116 is bonded to and in contact with the fourth surface 144 of the oil guide member 140. The oil storage section 116 applies gravity to the oil guide member 140, so that the oil guide member 140 is sandwiched between the oil storage section 116 and the top plate 128 of the atomizing bracket 120, so that the oil guide member 140 can be better in contact with the resistance heating element 130, and the atomizing effect can be further enhanced. The oil storage section 116 may be oil storage cotton or other materials with oil storage function.

[0075] The top plate 128 of the atomizing bracket 120 is provided with a first exhaust hole 155 in the center, and the oil guide member 140 is provided with a second exhaust hole 161 corresponding to the first exhaust hole 155 in the center. A smoke exhaust passage 112 isolated from the oil storage chamber 111 is provided in the oil reservoir 110. The second exhaust hole 161 communicates the smoke exhaust passage 112 with the first exhaust hole 155. This allows the airflow in the atomizer 100 to flow to the smoke exhaust passage 112 via the first exhaust hole 155 and the second exhaust hole 161 in sequence.

[0076] The oil reservoir 110 includes an outer pipe 114 and an inner pipe 115 located in the outer pipe 114. The bottom end of the outer pipe 114 is an open end, and the inner pipe 115 is connected to the tip of the outer pipe 114. The oil storage chamber 111 is formed between the outer pipe 114 and the inner pipe 115. Specifically, the oil storage chamber 111 is an annular groove provided around the inner pipe 115. A smoke exhaust passage 112 is formed inside the inner pipe 115. In this embodiment, the inner pipe 115 is integral with the tip of the outer pipe 114, that is, the inner pipe 115 is molded integrally with the outer pipe 114. The oil storage section 116 is hollow and cylindrical, and has a through hole 117 in the center. The oil storage section 116 is covered on the inner pipe 115 via the through hole 117.

[0077] The atomizer 100 further includes an atomizing base 170 attached to the bottom open end of the outer tube 114. The atomizing base 170 includes a bottom plate 171 and a side wall 172 extending upward from the periphery of the bottom plate 171. The side wall 122 of the atomizing bracket 120 is sandwiched between the side wall 172 of the atomizing base 170 and the inner wall of the outer tube 114. The bottom end of the inner tube 115 is inserted into the second exhaust hole 161 and abuts against the upper surface of the top plate 128 of the atomizing bracket 120. Preferably, in this embodiment, the atomizing bracket 120 is made of rubber or silicone resin. That is, the atomizing bracket 120 is soft and has a sealing function. Therefore, the atomization bracket 120 can prevent the smoke oil in the oil storage chamber 111 from leaking out from the bottom opening end of the outer tube 114, and furthermore, there is no need to provide a seal cover 160 as described in the first embodiment above, resulting in a simpler structure.

[0078] As shown in Fig. 18 and Fig. 20 to 23, two positioning pins 174 are provided on the inner surface of the bottom plate 171 of the atomization base 170, extending upward. The vertical portions 1366 of the two conductive pins 136 pass through the two positioning pins 174, respectively, and are exposed to the outside of the oil reservoir 110. The exposed conductive pins 136 can be easily electrically connected to a power supply device (not shown).

[0079] In the atomizing base 170, a storage chamber 129 is formed between the bottom plate 171 and the top plate 128 of the atomizing bracket 120. An oil absorbing member 183 is provided in the storage chamber 129. Specifically, the oil absorbing member 183 is U-shaped. The oil absorbing member 183 is provided with a notch 184 corresponding to the first exhaust hole 155. Therefore, the oil absorbing member 183 occupies only a partial space of the internal cavity of the atomizing base 170. The oil absorbing member 183 can absorb condensed liquid or smoke oil generated during the atomizing operation and prevent the condensed liquid or smoke oil from flowing out. The oil absorbing member 183 may be oil absorbing cotton or other materials with oil absorbing function.

[0080] As shown in Figures 20, 21, 23 and 25, an air intake hole 173 is provided on the bottom plate 171 of the atomizing base 170. The external airflow enters the storage chamber 129 from the air intake hole 173, and is exhausted together with the smoke generated by atomization through the first exhaust hole 155, the second exhaust hole 161 and the smoke exhaust passage 112 in order, so that the user can inhale it.

[0081] As shown in Figures 20, 21 and 23, a deflector 176 is inclined and extended toward the side wall 172 of the atomizing base 170 on the inner surface of the bottom plate 171 of the atomizing base 170. The deflector 176 is located directly below the atomizing opening 126. The air intake hole 173 is provided between the deflector 176 and the side wall 172 of the atomizing base 170. The condensed liquid or smoke oil generated during the atomizing operation is guided to the storage chamber 129 by the deflector 176 and collected, and is absorbed by the oil absorbing member 183 located in the storage chamber 129, preventing the condensed liquid or smoke oil from leaking through the air intake hole 173.

[0082] As shown in Figures 18, 20 and 21, the atomization opening 126 is provided through one side of the top plate 128 of the atomization bracket 120. A plurality of through holes 133 for forming a heating fence 135 are formed in the center of the resistance heating element 130. The heating fence 135 is connected to the atomization opening 126. The smoke generated by atomization enters the airflow passage in the atomizer 100 through the heating fence 135 and the atomization opening 126, and is removed by the external airflow that has entered the atomizer 100, allowing the user to inhale.

[0083] When the atomizer 100 operates, the smoke oil stored in the oil storage section 116 in the oil reservoir 110 is transferred to the oil guide member 140. The smoke oil is absorbed by the oil guide member 140 and then transferred to the third surface 143 completely bonded to the resistance heating element 130. During energization, the resistance heating element 130 generates heat and atomizes the smoke oil in contact with the first surface 131 of the resistance heating element 130 to form smoke. The smoke formed by atomization passes through the heating fence 135 and the atomization opening 126 and enters the storage chamber 129 of the atomization base 170. As shown by the airflow direction arrow in FIG. 21, the external airflow enters the atomizer 100 from the intake hole 173 in the atomization base 170, and is discharged via the first exhaust hole 155, the second exhaust hole 161, and the smoke exhaust passage 112 together with the smoke formed by atomization, so that the user can inhale it.

[0084] In this embodiment, the resistance heating element is bonded to the upper surface of the atomizing bracket to form a heating assembly. The assembly of such a heating assembly is simple, and automated assembly and production can be realized. The assembly process does not require the complicated assembly process of wrapping oil guide cotton on the outer surface of the resistance heating element, such as the vertical cotton batting, which effectively improves the production efficiency and product stability, and effectively guarantees the quality consistency of the atomizing assembly.

[0085] In this embodiment, an oil guide member is interposed between the oil storage member in the oil reservoir and the heating assembly. When subjected to the gravity of the oil reservoir, the oil guide member comes into intimate contact with the resistance heating element in the heating assembly, forming an atomization structure with heating ability and oil guide channel, effectively improving the atomization effect, and avoiding the generation of burnt odor during the atomization process from affecting the taste of smoking.

[0086] The present invention further provides an electronic cigarette including the atomizer described above.

[0087] The electronic cigarette further includes a power supply (not shown) electrically connected to the atomizer, the power supply including a battery and providing the power required for operation of the atomizer.

[0088] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
