Description

Technical Field

[0001] This invention relates to the field of electronic atomization technology, and in particular to a heating element, an atomizer, and an electronic cigarette having the atomizer. Background Technology

[0002] The atomizer is the core component of electronic atomization products, and the reliability of the atomizer determines the quality of the entire atomization product.

[0003] One existing atomization structure consists of a porous ceramic material with a printed heating paste or a metal resistive heating element embedded in its surface. Both methods use porous ceramic as the oil-conducting material to absorb e-liquid onto the surface of the resistive heating element. When the resistive heating element is powered on, it generates heat to atomize the e-liquid. The ceramic molding process for these atomization structures is complex, the yield rate is low, and the consistency of the ceramic is poor. As a result, the product cost is high, and the ceramic's oil-conducting properties are slightly poor, which can easily lead to a burnt taste and a slightly poorer flavor reproduction.

[0004] Another existing atomization structure is: a spiral resistance heating wire is wound around the surface of the transverse cotton core. The transverse cotton core absorbs the e-liquid onto the surface of the resistance heating wire. When the resistance heating wire is energized, it generates heat and atomizes the e-liquid. This type of atomization structure makes the transverse cotton core very easy to deform, which makes assembly difficult. Moreover, the long oil guiding distance makes it easy to produce a burnt taste.

[0005] Another existing atomization structure is as follows: the outer surface of the vertical cotton core resistor heating element is wrapped with oil-guiding cotton, and the inner side of the resistor heating element is hollow; the oil-guiding cotton wrapped on the outer surface absorbs the e-liquid to the surface of the resistor heating element, and heat is generated when the resistor heating wire is energized, thereby atomizing the e-liquid; this type of atomization structure has many parts in the vertical cotton core structure, and the assembly is complicated, resulting in high product cost.

[0006] The existing atomization structures have all failed to meet the requirements for product quality stability and automated production. Summary of the Invention

[0007] The purpose of this invention is to provide a heating element and atomizer with high quality stability and automated production assembly, aiming to solve problems such as poor product quality consistency, difficult assembly, and high cost.

[0008] This invention provides a heating component for an atomizer, including a resistance heating element and an atomizing bracket. The resistance heating element is combined with the atomizing bracket. The resistance heating element includes a flat plate portion and a hollow portion. The atomizing bracket includes an atomizing groove, and the atomizing groove corresponds to the hollow portion.

[0009] This invention also provides an atomizer, including an atomizing bracket, a resistance heating element, and an oil guide. The resistance heating element is combined with the atomizing bracket. The resistance heating element includes a flat portion and a hollow portion. The atomizing bracket includes an atomizing groove. The resistance heating element includes a first surface facing the oil guide and a second surface away from the oil guide. The oil guide includes a third surface facing the resistance heating element and a fourth surface away from the resistance heating element. The oil guide is disposed on the resistance heating element. The third surface of the oil guide is in close contact with the first surface of the resistance heating element. The atomizing groove corresponds to the hollow portion.

[0010] This invention also provides an electronic cigarette, including the atomizer described above.

[0011] The heating component and atomizer provided in this invention combine a resistance heating element with an atomizing bracket to form a heating component. This heating component is simple to assemble and can be automated, effectively improving production efficiency and product stability, and ensuring consistent quality of the atomizing component. Simultaneously, the oil guide component is in close contact with the resistance heating element on the heating component, effectively improving the atomization effect and preventing a burnt taste that would affect the inhalation experience.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] It should be noted that in this article, 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 any such actual relationship or order between these entities or operations.

[0035] First Embodiment

[0036] Please refer to Figures 1 to 6 The first embodiment of the present invention provides an atomizer 100, including an oil storage chamber 110 and an atomizing support 120, a resistance heating element 130 and an oil guide 140 housed in the oil storage chamber 110.

[0037] Please refer to Figures 7 to 11 The resistive heating element 130 is combined with the atomizing bracket 120, and the oil guiding element 140 is disposed on the resistive heating element 130. The resistive heating element 130 has a sheet-like structure and is made of a thin metal sheet. The resistive heating element 130 includes a flat plate portion 134, a hollow portion 135, a first surface 131 facing the oil guiding element 140, and a second surface 132 away from the oil guiding element 140, wherein 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 groove 126, which corresponds to the hollow portion 135. The oil guiding element 140 includes a third surface 143 facing the resistive heating element 130 and a fourth surface 144 away from the resistive heating element 130, wherein the third surface 143 is the lower surface of the oil guiding element 140, and the fourth surface 144 is the upper surface of the oil guiding element 140. The third surface 143 of the oil guide 140 is in contact with the first surface 131 of the resistive heating element 130.

[0038] In this embodiment, the resistive heating element 130 is combined with the atomizing bracket 120, and then the oil guide 140 is directly in contact with the resistive heating element 130. This assembly method is simple and can achieve automated assembly production, effectively improving production efficiency and product stability, and effectively ensuring the consistency of the quality of the atomizing components. Moreover, the complete contact between the resistive heating element 130 and the oil guide 140 effectively enhances the atomization effect and avoids the generation of a burnt taste during atomization, which would affect the inhalation experience.

[0039] Please refer to Figure 7-11Specifically, the first surface 131 and the second surface 132 of the resistive heating element 130 are both planar, and the first surface 131 and the second surface 132 are parallel to each other. The oil guide 140 has a sheet-like structure, and the third surface 143 and the fourth surface 144 of the oil guide 140 are both planar, and the third surface 143 and the fourth surface 144 are parallel to each other. The sheet-like oil guide 140 allows the e-liquid to be evenly absorbed and transferred to the sheet-like resistive heating element 130, thereby improving the atomization effect. The oil guide 140 can be an oil-guiding cotton.

[0040] The resistive heating element 130 has a plurality of notches 133 hollowed out in the middle to form a hollow portion 135, thus forming two flat portions 134 and a hollow portion 135 in the middle. The two flat portions 134 and the hollow portion 135 are located on the same plane, with the two flat portions 134 located on both sides of the hollow portion 135, and the hollow portion 135 located between the two flat portions 134, which are connected by the hollow portion 135. The heating wire is located between adjacent notches 133 of the hollow portion 135, which is also the heating part of the resistive heating element 130. The vapor produced by atomization can enter the airflow channel inside the atomizer 100 through these notches 133, and is carried away by the external airflow entering the atomizer 100 for the user to inhale.

[0041] The resistive heating element 130 also includes two conductive pins 136, which are respectively disposed corresponding to two flat plate portions 134. Each conductive pin 136 is electrically connected to the corresponding flat plate portion 134. In this embodiment, the atomizing bracket 120 is spaced between each conductive pin 136 and the corresponding flat plate portion 134. Each conductive pin 136 is connected to the corresponding flat plate portion 134 through a bending portion 139. The two conductive pins 136 are located at the bottom of the atomizing bracket 120 and are exposed outside the atomizing bracket 120. The two conductive pins 136 are in contact with the bottom surface of the atomizing bracket 120. In this embodiment, two conductive pins 136 extend from both ends of the resistive heating element 130 outwards from the outer side of the atomizing bracket 120 and bend downwards and inwards. Specifically, the two conductive pins 136 are formed by bending downwards and inwards from the outer side of the two flat plate portions 134, respectively. Each conductive pin 136 is exposed on the lower surface of the atomizing bracket 120, thereby facilitating communication between the exposed conductive pins 136 and the conductive electrode 175. Figure 5 Conductive connection.

[0042] The resistance heating element 130 is made of metal, such as nickel-chromium alloy, iron-chromium-aluminum, or S316L stainless steel. The atomizing bracket 120 is made of plastic, rubber, or silicone. The resistance heating element 130 is bonded to the atomizing bracket 120 via insert molding. Specifically, during the fabrication of the atomizing bracket 120, the resistance heating element 130 is placed into the cavity of a mold (not shown), and molten plastic, rubber, or silicone is injected into the cavity of the mold. The molten plastic, rubber, or silicone coats the periphery of the resistance heating element 130 and, after cooling, forms the atomizing bracket 120. Thus, the resistance heating element 130 is at least partially embedded in the atomizing bracket 120, and the bottom and outer edges of the two flat plates 134 and the outer edge of the hollow portion 135 are integrated with the atomizing bracket 120.

[0043] Please refer to Figure 10 and Figure 11 After the resistance heating element 130 is embedded into the atomizing bracket 120 by insert injection molding, both ends of the resistance heating element 130 extend horizontally outward from the outer side of the atomizing bracket 120. Figure 10 Then, using a tool (not shown), the two ends of the resistive heating element 130 are bent downwards and inwards to form two conductive leads 136. Figure 11 Two conductive pins 136 are connected to two flat plates 134 respectively via bending portions 139 and are exposed below the two flat plates 134 respectively. Each conductive pin 136 is in contact with the lower surface of the base plate 121 of the atomizing bracket 120.

[0044] The resistance heating element 130 and the atomizing bracket 120 are combined to form a heating component.

[0045] Please refer to Figure 7-11 The atomizing support 120 includes a base plate 121 and sidewalls 122 extending upward from the periphery of the base plate 121. A receiving cavity 123 is formed within the atomizing support 120, surrounded by the base plate 121 and sidewalls 122. The upper end of the receiving cavity 123 forms an opening 123A. An atomizing groove 126 is formed in the middle of the base plate 121 and extends through the upper and lower surfaces of the base plate 121. The atomizing groove 126 corresponds to a cutout portion 135, meaning the cutout portion 135 is positioned corresponding to the atomizing groove 126, aligning the cutout portion 135 vertically with the atomizing groove 126. The atomizing groove 126 communicates with the receiving cavity 123, and the cutout portion 135 is exposed above the atomizing groove 126, spanning across the atomizing groove 126.

[0046] Please refer to Figure 9 and Figure 11The second surface 132 of the resistive heating element 130 is higher than the lower surface of the base plate 121 of the atomizing bracket 120, and a certain distance is formed between the two, preferably 0.5mm-2.0mm.

[0047] The outer contour of the wicking element 140 matches the shape of the receiving cavity 123, and the wicking element 140 is placed inside the receiving cavity 123 through the opening 123A at the upper end of the receiving cavity 123. The wicking element 140 is flatly disposed within the receiving cavity 123 of the atomizer holder 120. The wicking element 140 is independently disposed of from the atomizer holder 120 and the resistance heating element 130, and the wicking element 140 can be detachably housed within the receiving cavity 123, that is, the wicking element 140 can be placed inside the receiving cavity 123 or removed from the receiving cavity 123. The wicking element 140 has the ability to absorb oil, but the atomizer holder 120 does not have the ability to absorb oil. The atomizer holder 120 is used to connect the resistance heating element 130 and to house and support the wicking element 140. By confining the oil guide 140 within the receiving cavity 123, the e-liquid absorbed by the oil guide 140 into the receiving cavity 123 can only be supplied downward to the resistive heating element 130 for atomization, which can effectively prevent e-liquid leakage and splashing during atomization.

[0048] Please refer to Figure 7 and Figure 11 The base plate 121 of the atomizing bracket 120 includes a bearing surface 124 that is in contact with the third surface 143 of the oil guide 140. Specifically, the bearing surface 124 is the upper surface of the base plate 121. The first surface 131 of the resistive heating element 130 is flush with the upper surface of the base plate 121, that is, the upper surface of the hollow portion 135 is flush with the upper surface of the base plate 121, and the upper surface of the flat portion 134 is flush with the upper surface of the base plate 121. The first surface 131 of the resistive heating element 130 is exposed outside the base plate 121 of the atomizing bracket 120, that is, the upper surfaces of the flat portion 134 and the upper surfaces of the hollow portion 135 are exposed outside the base plate 121 of the atomizing bracket 120. When the oil guide 140 is placed in the receiving cavity 123, the third surface 143 of the oil guide 140 is in contact with the first surface 131 of the resistance heating element 130 and the upper surface (i.e., the bearing surface 124) of the base plate 121, so that the oil guide 140 is flatly placed in the receiving cavity 123 of the atomizing bracket 120. Furthermore, the third surface 143 of the oil guide 140 is in contact with the upper surface of the hollow portion 135 of the resistance heating element 130 and the upper surface (i.e., the bearing surface 124) of the base plate 121. Preferably, the third surface 143 of the oil guide 140 is also in contact with the upper surface of the flat plate portion 134 of the resistance heating element 130.

[0049] Please refer to Figure 11Each conductive pin 136 is in contact with the lower surface of the base plate 121, and each flat plate portion 134 is located on the upper surface of the base plate 121, above a corresponding conductive pin 136. Each flat plate portion 134 and its corresponding conductive pin 136 are disposed opposite each other on the upper and lower surfaces of the base plate 121, separated by the base plate 121 of the atomizing bracket 120. Each flat plate portion 134 and its corresponding conductive pin 136 are connected by a bending portion 139. The flat plate portion 134, the hollow portion 135, the conductive pin 136, and the bending portion 139 are an integral structure.

[0050] Please refer to Figure 8 and Figure 11 The oil guide 140 is completely housed within the receiving cavity 123. The fourth surface 144 of the oil guide 140 is lower than the upper surface of the side wall 122 of the atomizing bracket 120, so that a cavity 123B is formed within the atomizing bracket 120 by the fourth surface 144 of the oil guide 140 and the side wall 122 of the atomizing bracket 120.

[0051] Please refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 The atomizer 100 also includes an oil guide bracket 150 housed within the oil reservoir 110. The oil guide bracket 150 is positioned above the atomizing bracket 120. The bottom end of the oil guide bracket 150 has an annular pressure wall 151 that extends into the cavity 123B and presses against the periphery of the fourth surface 144 of the oil guide component 140. The pressure wall 151 applies downward pressure to the oil guide component 140, clamping it between the pressure wall 151 and the base plate 121 of the atomizing bracket 120. This prevents the oil guide component 140 from loosening or shifting, ensuring better contact and adhesion between the oil guide component 140 and the resistive heating element 130, thereby improving the atomization effect.

[0052] The bottom end of the oil guide bracket 150 is also provided with two opposing baffles 152, and a pressure wall 151 is located between the two baffles 152, forming a gap 153 between the pressure wall 151 and the two baffles 152. The side wall 122 of the atomizing bracket 120 is inserted into the gap 153. By confining the side wall 122 of the atomizing bracket 120 within the gap 153, the atomizing bracket 120 can be stably installed in the atomizer 100.

[0053] A sealing sheet 181 is also provided within the gap 153. The sealing sheet 181 is sandwiched between the upper surface of the side wall 122 of the atomizing bracket 120 and the bottom end face of the oil guide bracket 150. The sealing sheet 181 has a sheet-like structure and a through hole (not shown in the figure) in the middle for the pressure wall 151 to pass through. The sealing sheet 181 can prevent the e-liquid absorbed into the receiving cavity 123 from leaking out from the upper surface of the side wall 122.

[0054] The top of the oil guide bracket 150 is provided with two first liquid inlet holes 154 on both sides. The oil storage tank 110 is provided with an oil storage cavity 111. Each first liquid inlet hole 154 connects the oil storage cavity 111 with the oil guide component 140, so that the e-liquid in the oil storage cavity 111 can be transferred to the oil guide component 140 through the first liquid inlet hole 154.

[0055] The top of the oil guide bracket 150 is provided with a first air outlet 155 in the middle. The first air outlet 155 is located between two first liquid inlets 154. The oil storage chamber 110 is provided with a smoke outlet channel 112 that is isolated from the oil storage chamber 111. The side wall 122 of the atomizing bracket 120 and the oil storage chamber 110 form an air outlet channel 113. The first air outlet 155 connects the smoke outlet channel 112 and the air outlet channel 113, so that the airflow in the atomizer 100 can flow to the smoke outlet channel 112 through the air outlet channel 113 and the first air outlet 155.

[0056] The atomizer 100 also includes a sealing cap 160 housed within the oil reservoir 110, positioned above the wicking bracket 150. The sealing cap 160 has a second air outlet 161 at its center, which connects the smoke outlet channel 112 to the first air outlet 155, allowing airflow within the atomizer 100 to sequentially flow through the air outlet channel 113, the first air outlet 155, and the second air outlet 161 to the smoke outlet channel 112. The sealing cap 160 has two second liquid inlets 162 on both sides, each connecting the oil reservoir 111 to a corresponding first liquid inlet 154, allowing e-liquid within the oil reservoir 111 to be sequentially transferred to the wicking component 140 via the second liquid inlet 162 and the first liquid inlet 154.

[0057] The oil storage tank 110 includes an outer pipe 114 and an inner pipe 115 located inside 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 top end of the outer pipe 114. An oil storage cavity 111 is formed between the outer pipe 114 and the inner pipe 115. Specifically, the oil storage cavity 111 is an annular groove surrounding the inner pipe 115. A smoke outlet channel 112 is formed inside the inner pipe 115, and an air outlet channel 113 is formed between the side wall 122 of the atomizing bracket 120 and the inner wall of the outer pipe 114. In this embodiment, the top ends of the inner pipe 115 and the outer pipe 114 are an integral structure, that is, the inner pipe 115 and the outer pipe 114 are integrally manufactured.

[0058] The sealing cap 160 has a side wall 163, and the top of the oil guide bracket 150 has a side wall 156. The side wall 163 of the sealing cap 160 is sandwiched between the side wall 156 at the top of the oil guide bracket 150 and the inner wall of the outer tube 114. The bottom end of the inner tube 115 is inserted into the second air outlet 161 so that the outer wall of the bottom end of the inner tube 115 is tightly against the sealing cap 160 to prevent the e-liquid in the oil storage chamber 111 from leaking out.

[0059] The atomizer 100 also includes an atomizing base 170, which is located below the atomizing bracket 120 and is installed at the open end of the bottom of the outer tube 114. The atomizing base 170 includes a base plate 171 and sidewalls 172 extending upward from all sides of the base plate 171. The base plate 171 of the atomizing base 170 is provided with an air inlet 173. External gas enters the outer tube 114 through the air inlet 173 and carries the smoke generated by atomization through the air outlet channel 113, the first air outlet 155, the second air outlet 161, and the smoke outlet channel 112 for the user to inhale.

[0060] The atomizer 100 also includes a sealing ring 182 housed in the oil reservoir 110. The sealing ring 182 has a ring-shaped structure and is sandwiched between the side wall 172 of the atomizing base 170 and the inner wall of the outer tube 114 to prevent e-liquid from leaking out from the opening at the bottom of the outer tube 114.

[0061] The inner surface of the base plate 171 of the atomizing base 170 extends upwards and is provided with two positioning posts 174. The atomizer 100 also includes two conductive electrodes 175, which are respectively inserted into the two positioning posts 174, and the top ends of the two conductive electrodes 175 are in conductive contact with the two conductive pins 136 of the resistive heating element 130. The bottom ends of the two conductive electrodes 175 protrude outside the oil reservoir 110, facilitating the conductive connection of the two conductive electrodes 175 to the power supply device (not shown).

[0062] The atomizer 100 also includes an oil-absorbing component 183 housed within the oil reservoir 110. The oil-absorbing component 183 has a sheet-like structure and is disposed on the inner surface of the base plate 171 of the atomizer base 170 and fitted onto two positioning posts 174. The oil-absorbing component 183 can absorb condensate or e-liquid generated during atomization, preventing condensate or e-liquid leakage. The oil-absorbing component 183 is made of absorbent cotton or other materials with oil-absorbing functions.

[0063] Please refer to Figures 9-11 The base plate 121 of the atomizing bracket 120 has an atomizing groove 126 running through its center. The resistive heating element 130 has a hollowed-out portion 135 in its center, which corresponds to the atomizing groove 126. The vapor produced by atomization can pass through the hollowed-out portion 135 and the atomizing groove 126 into the airflow channel inside the atomizer 100, and is carried away by the external airflow entering the atomizer 100 for the user to inhale.

[0064] When the atomizer 100 is working, the e-liquid stored in the oil storage chamber 111 of the oil reservoir 110 enters the fourth surface 144 of the wicking component 140 through the second inlet 162 on the sealing cap 160 and the first inlet 154 on the wicking bracket 150. After being absorbed by the wicking component 140, it is transferred to the third surface 143, which is completely in contact with the resistive heating element 130. Figure 5 The liquid flow is indicated by the arrow. When powered on, the resistance heating element 130 generates heat, atomizing the e-liquid in contact with the first surface 131 of the resistance heating element 130 to form smoke. The atomized smoke enters the inner cavity of the atomizing base 170 through the perforated portion 135 and the atomizing groove 126. External gas enters the inner cavity of the atomizing base 170 through the air inlet 173, carrying the atomized smoke through the air outlet 113, the first air outlet 155, the second air outlet 161, and the smoke outlet 112, for the user to inhale. Figure 6 The airflow direction is shown by the arrow.

[0065] In this embodiment, the resistive heating element is molded together with the atomizing bracket and plastic, rubber or silicone to form a heating component. Such a heating component can be automatically produced from the molding mold. After molding, it does not need to undergo cumbersome post-processing like ceramics, which effectively improves production efficiency and product stability, and effectively ensures the quality consistency of the atomizing component.

[0066] In this embodiment, a sheet-shaped oil guide is installed in the inner cavity of the heating component, and then an oil guide bracket is installed. Under the pressure of the oil guide bracket, the sheet-shaped oil guide is in close contact with the resistive heating element on the heating component, thus becoming an atomizing component with heating capacity and an oil guide channel, which effectively improves the atomization effect and avoids the problem of burning taste during atomization, which affects the inhalation taste.

[0067] Second Embodiment

[0068] Please refer to Figures 12 to 15 The second embodiment of the present invention provides an atomizer 100, including an oil storage chamber 110 and an atomizing support 120, a resistance heating element 130 and an oil guide 140 housed in the oil storage chamber 110.

[0069] Please refer to the diagram. Figures 14 to 19The resistive heating element 130 is combined with the atomizing bracket 120, and the oil guiding element 140 is disposed on the resistive heating element 130. The resistive heating element 130 has a sheet-like structure and is made of a thin metal sheet. The resistive heating element 130 includes a flat plate portion 134, a hollow portion 135, a first surface 131 facing the oil guiding element 140, and a second surface 132 away from the oil guiding element 140, wherein 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 groove 126, which corresponds to the hollow portion 135. The oil guiding element 140 includes a third surface 143 facing the resistive heating element 130 and a fourth surface 144 away from the resistive heating element 130, wherein the third surface 143 is the lower surface of the oil guiding element 140, and the fourth surface 144 is the upper surface of the oil guiding element 140. The third surface 143 of the oil guide 140 is in contact with the first surface 131 of the resistive heating element 130.

[0070] In this embodiment, the resistive heating element 130 is combined with the atomizing bracket 120, and then the oil guide 140 is directly in contact with the resistive heating element 130. This assembly method is simple and can achieve automated assembly production, effectively improving production efficiency and product stability, and effectively ensuring the consistency of the quality of the atomizing components. Moreover, the complete contact between the resistive heating element 130 and the oil guide 140 effectively enhances the atomization effect and avoids the generation of a burnt taste during atomization, which would affect the inhalation experience.

[0071] Please refer to Figure 20 and Figure 21 Specifically, the first surface 131 and the second surface 132 of the resistive heating element 130 are both planar, and the first surface 131 and the second surface 132 are parallel to each other.

[0072] Please refer to Figure 12 and Figure 14 The oil-guiding component 140 has a sheet-like structure, with both the third surface 143 and the fourth surface 144 being planar and parallel to each other. The sheet-like oil-guiding component 140 allows the e-liquid to be evenly absorbed and transferred to the resistive heating element 130, thereby improving the atomization effect. The oil-guiding component 140 can be an oil-guiding cotton.

[0073] Please refer to Figure 14-15 and Figure 20-21The resistive heating element 130 has a plurality of notches 133 hollowed out in the middle to form a hollow section, thus forming two flat sections 134 and a hollow section 135 in the middle. The two flat sections 134 and the hollow section 135 are located on the same plane, with the two flat sections 134 located on both sides of the hollow section 135, and the hollow section 135 located between the two flat sections 134, which are connected by the hollow section 135. The heating wire is located between adjacent notches 133 of the hollow section 135, which is also the heating section of the resistive heating element 130. The vapor produced by atomization can enter the airflow channel inside the atomizer 100 through these notches 133, and is carried away by the external airflow entering the atomizer 100 for the user to inhale.

[0074] Please refer to Figure 14-21 The atomizing bracket 120 includes a top plate 128 and sidewalls 122 extending downward from the periphery of the top plate 128. The resistive heating element 130 also includes two conductive pins 136, which are electrically connected to two flat plate portions 134 respectively. In this embodiment, each conductive pin 136 includes a horizontal portion 137 and a vertical portion 138. One end of the horizontal portion 137 is connected to the corresponding flat plate portion 134, and the vertical portion 138 extends downward from the other end of the horizontal portion 137, extending downward through the top plate 128. The upper surface of the atomizing bracket 120 is provided with a slot 127, and the horizontal portion 137 is disposed in the slot 127, so that the resistive heating element 130 is at least partially embedded in the top plate 128 of the atomizing bracket 120, thereby realizing the combination of the resistive heating element 130 and the atomizing bracket 120. The downwardly bent vertical portion 138 facilitates conductive connection with a power supply device (not shown). In this embodiment, the vertical part 138 and the horizontal part 137 form a 90-degree angle.

[0075] The resistance heating element 130 is made of metal, such as nickel-chromium alloy, iron-chromium-aluminum, or S316L stainless steel. The atomizing bracket 120 is made of plastic, rubber, or silicone. Alternatively, the resistance heating element 130 can be integrated with the atomizing bracket 120 via insert molding, embedding the two flat sections 134 and the hollow section 135 within the atomizing bracket 120. Specifically, during the fabrication of the atomizing bracket 120, the resistance heating element 130 is placed into the cavity of a mold (not shown), and molten plastic, rubber, or silicone is injected into the cavity. The molten plastic, rubber, or silicone coats the periphery of the resistance heating element 130 and, after cooling, forms the atomizing bracket 120, thus embedding the resistance heating element 130 within the atomizing bracket 120.

[0076] The resistance heating element 130 and the atomizing bracket 120 are combined to form a heating component.

[0077] Please refer to Figure 14-19 The atomizer bracket 120 includes a top plate 128 and sidewalls 122 extending downwards from all sides of the top plate 128. A resistance heating element 130 is embedded in the top plate 128 of the atomizer 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 atomizer bracket 120, and the third surface 143 of the wicking element 140 is also in contact with the upper surface of the top plate 128 of the atomizer bracket 120. The wicking element 140 is independently provided from the atomizer bracket 120 and the resistance heating element 130. The wicking element 140 has the ability to absorb oil, but the atomizer bracket 120 does not have the ability to absorb oil. The atomizer bracket 120 is used to connect the resistance heating element 130 and support the wicking element 140.

[0078] The atomizing groove 126 is formed on one side of the top plate 128 and extends through the upper and lower surfaces of the top plate 128. The atomizing groove 126 corresponds to the hollow portion 135, that is, the hollow portion 135 is set at a position corresponding to the atomizing groove 126, so that the hollow portion 135 and the atomizing groove 126 are vertically aligned. The hollow portion 135 is located above the atomizing groove 126 and spans across the atomizing groove 126.

[0079] Please refer to Figure 14 and Figure 15 The second surface 132 of the resistive heating element 130 is higher than the lower surface of the top plate 128 of the atomizing bracket 120, and a certain distance is formed between the two, preferably 0.5mm-2.0mm.

[0080] Please refer to Figure 14-19 The top plate 128 of the atomizing bracket 120 includes a bearing surface 124 that is in contact with the third surface 143 of the oil guide 140. Specifically, the bearing surface 124 is the upper surface of the top plate 128. The first surface 131 of the resistive heating element 130 is flush with the upper surface of the top plate 128. The third surface 143 of the oil guide 140 is in contact with the first surface 131 of the resistive heating element 130 and the upper surface of the top plate 128 (i.e., the bearing surface 124), so that the oil guide 140 is flatly disposed on the upper surface of the top plate 128.

[0081] In other embodiments, the first surface 131 of the resistive heating element 130 may also be slightly higher than the upper surface of the top plate 128, so that the first surface 131 of the resistive heating element 130 can be slightly embedded in the oil guide 140 under the gravity of the oil storage element 116, thereby improving the contact and liquid guiding effect between the two.

[0082] Please refer to Figure 12 and Figure 14-15The oil storage chamber 110 contains an oil storage cavity 111, and an oil storage component 116 is located within the oil storage cavity 111. The oil storage component 116 is a hollow cylindrical shape, and its shape matches the oil storage cavity 111, allowing it to be properly housed within the cavity. The bottom surface of the oil storage component 116 is in close contact with the fourth surface 144 of the oil guide component 140. By applying gravity to the oil guide component 140 through the oil storage component 116, the oil guide component 140 is sandwiched between the oil storage component 116 and the top plate 128 of the atomizing bracket 120. This allows the oil guide component 140 to better adhere and contact the resistance heating element 130, thereby improving the atomization effect. The oil storage component 116 can be oil-retaining cotton or other materials with oil-retaining functions.

[0083] The top plate 128 of the atomizing bracket 120 has a first air outlet 155 in the middle, and the oil guide 140 has a second air outlet 161 in the middle corresponding to the first air outlet 155. The oil storage chamber 110 has a smoke outlet channel 112 isolated from the oil storage chamber 111. The second air outlet 161 connects the smoke outlet channel 112 with the first air outlet 155, so that the airflow in the atomizer 100 can flow to the smoke outlet channel 112 in sequence through the first air outlet 155 and the second air outlet 161.

[0084] The oil storage tank 110 includes an outer pipe 114 (also referred to as the outer pipe 114) and an inner pipe 115 (also referred to as the inner pipe 115) located inside 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 top end of the outer pipe 114. An oil storage cavity 111 is formed between the outer pipe 114 and the inner pipe 115. Specifically, the oil storage cavity 111 is an annular groove surrounding the inner pipe 115. A smoke outlet channel 112 is formed inside the inner pipe 115. In this embodiment, the top ends of the inner pipe 115 and the outer pipe 114 are integral structures, that is, the inner pipe 115 and the outer pipe 114 are integrally manufactured. The oil storage component 116 is a hollow cylindrical shape, and a through hole 117 is provided through the middle of the oil storage component 116. The oil storage component 116 is sleeved on the inner pipe 115 through the through hole 117.

[0085] The atomizer 100 also includes an atomizing base 170, which is installed at the open end of the bottom of the outer tube 114. The atomizing base 170 includes a base plate 171 and sidewalls 172 extending upward from the periphery of the base plate 171. The sidewalls 122 of the atomizing bracket 120 are sandwiched between the sidewalls 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 air outlet 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 soft rubber or silicone, that is, the atomizing bracket 120 itself has a sealing function. Therefore, the atomizing bracket 120 can also prevent the e-liquid in the oil storage chamber 111 from leaking out from the open end of the bottom of the outer tube 114, eliminating the need for the sealing cap 160 as described in the first embodiment above, resulting in a simpler structure.

[0086] Please refer to Figure 12 and Figure 14-17 The inner surface of the base plate 171 of the atomizing base 170 extends upward and is provided with two positioning posts 174. The vertical parts 138 of the two conductive pins 136 pass through the two positioning posts 174 and are exposed outside the oil storage tank 110. The exposed conductive pins 136 facilitate conductive connection with the power supply device (not shown).

[0087] A cavity 129 is formed within the atomizer base 170 between its bottom plate 171 and the top plate 128 of the atomizer support 120. An oil-absorbing component 183 is disposed within the cavity 129. Specifically, the oil-absorbing component 183 is U-shaped, and a notch 184 is provided corresponding to the first air outlet 155. Therefore, the oil-absorbing component 183 only occupies a portion of the internal space of the atomizer base 170. The oil-absorbing component 183 absorbs condensate or e-liquid produced during atomization, preventing leakage. The oil-absorbing component 183 can be absorbent cotton or other materials with oil-absorbing properties.

[0088] Please refer to Figure 14-15 and Figure 17-19 The base plate 171 of the atomizing base 170 is provided with an air inlet 173. External gas enters the receiving cavity 129 through the air inlet 173 and carries the smoke generated by atomization through the first air outlet 155, the second air outlet 161 and the smoke outlet channel 112 for the user to inhale.

[0089] Please refer to Figure 14-15 and Figure 17 The inner surface of the base plate 171 of the atomizing base 170 extends obliquely towards the side wall 172 of the atomizing base 170 and is provided with a guide plate 176. The guide plate 176 is located directly below the atomizing groove 126, and the air inlet 173 is disposed between the guide plate 176 and the side wall 172 of the atomizing base 170. The condensate or e-liquid generated during atomization can be guided by the guide plate 176 to the receiving cavity 129 for collection, and absorbed by the oil absorption member 183 located in the receiving cavity 129, thereby preventing the condensate or e-liquid from leaking out.

[0090] Please refer to Figure 12 and Figure 14-15 The top plate 128 of the atomizing bracket 120 is provided with an atomizing groove 126. The middle part of the resistive heating element 130 is hollowed out to form a hollow part 135, which is set corresponding to the atomizing groove 126. The smoke generated by atomization can enter the airflow channel inside the atomizer 100 through the hollow part 135 and the atomizing groove 126, and be carried away by the external airflow entering the atomizer 100 for the user to inhale.

[0091] When the atomizer 100 is working, the e-liquid stored in the oil reservoir 116 within the oil tank 110 is transferred to the wicking component 140. After being absorbed by the wicking component 140, the e-liquid is transferred to the third surface 143, which is completely in contact with the resistive heating element 130. When powered on, the resistive heating element 130 generates heat, atomizing the e-liquid in contact with the first surface 131 of the resistive heating element 130 to form smoke. The atomized smoke enters the receiving cavity 129 of the atomizer base 170 through the perforated portion 135 and the atomization groove 126. External gas enters the receiving cavity 129 through the air inlet 173 on the atomizer base 170, carrying the atomized smoke through the first air outlet 155, the second air outlet 161, and the smoke outlet channel 112, for the user to inhale. Figure 13 The airflow direction is shown by the arrow.

[0092] In this embodiment, the resistive heating element is combined with the upper surface of the atomizing bracket to form a heating component. Such a heating component is simple to assemble and can be automated in production. The assembly process does not require the cumbersome assembly process of wrapping the outer surface of the resistive heating element with oil-guiding cotton, as is the case with vertical cotton cores. This effectively improves production efficiency and product stability, and effectively ensures the quality consistency of the atomizing component.

[0093] In this embodiment, the sheet-shaped oil guide is sandwiched between the oil storage component and the heating component in the oil storage chamber. Under the gravity of the oil storage component, the sheet-shaped oil guide is in close contact with the resistive heating element on the heating component, thus becoming an atomizing component with heating capacity and oil guiding channel, which effectively improves the atomization effect and avoids the problem of burning taste during atomization, which affects the inhalation taste.

[0094] The present invention also provides an electronic cigarette, including the atomizer described above.

[0095] Furthermore, the electronic cigarette also includes a power supply unit (not shown), which is electrically connected to the atomizer. The power supply unit contains a battery and provides the power required for the atomizer to operate.

[0096] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
