TECHNICAL FIELD

The present disclosure relates to the technical field of electronic atomization, and in particular, to a heating assembly, an atomizer, and an electronic cigarette with the atomizer.

BACKGROUND

Atomizer is the core part of electronic atomization products. The quality reliability of the atomizer determines the quality of the whole atomization product.
One of the existing atomizing structures is: the surface of ceramic porous material is printed and covered with heating slurry or the surface is embedded with metal resistive heating body. In both methods, porous ceramics are used as the oil conducting material to absorb smoke oil to the surface of the resistive heating body, which generates heat when the resistive heating body is energized, so as to atomize the smoke oil. The atomizing structures made by these methods have complex ceramic molding process, low yield and poor consistency of ceramics, so they have the disadvantages of high product cost, slightly poor oil conductivity of ceramics to easily produce burning smell, and slightly poor taste reduction.
Another existing atomizing structure is: the surface of a transverse cotton core is wrapped with a spiral resistive heating wire, the transverse cotton core absorbs the smoke oil to the surface of the resistive heating wire, and generates heat when the resistive heating wire is energized, so as to atomize the smoke oil. The transverse cotton core of the atomizing structure in this way is very easy to deform, resulting in difficult assembly, and the long oil guide distance is easy to produce burning smell.
A further existing atomizing structure is: the external surface of the resistive heating body of a vertical cotton core is wrapped with oil guide cotton, and the internal side of the resistive heating body is hollow. The oil guide cotton wrapped on the surface absorbs the smoke oil to the surface of the resistive heating body, and generates heat when the resistive heating body is energized, so as to atomize the smoke oil. The vertical cotton core of the atomizing structure in this way consists of many parts with complex assembly, resulting in high product cost.
From above, the existing atomizing structures fail to meet the requirements of the stability of product quality and automatic production.

SUMMARY

In view of the above, the object of the present disclosure is to provide a heating assembly and an atomizer with high quality stability and capable of automatic production and assembly, so as to at least partially solve the problems of poor consistency of product quality, difficult assembly and high cost.

The resistive heating element is combined with the atomizing bracket. The resistive heating element includes a first connecting portion, a second connecting portion and a heating fence, wherein the first connecting portion and the second connecting portion are interconnected by the heating fence. The atomizing bracket includes an atomizing opening in communication with the heating fence.
An embodiment of the present disclosure further provides an atomizer. The atomizer includes an atomizing bracket, a resistive heating element and an oil guiding member. The resistive heating element is combined with the atomizing bracket. The resistive heating element includes a first connecting portion, a second connecting portion and a heating fence, wherein the first connecting portion and the second connecting portion are interconnected by the heating fence.

Referring to FIGs. 7-11, the resistive heating element 130 is combined with the atomizing bracket 120, and the oil guiding member 140 is disposed on the resistive heating element 130. The resistive heating element 130 has a sheet structure, and the resistive heating element 130 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 guiding member 140 and a second surface 132 away from the oil guiding member 140, wherein the first connecting portion 134A and the second connecting portion 134B are interconnected 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 in communication with the heating fence 135. The oil guiding 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, wherein the third surface 143 is the lower surface of the oil guiding member 140 and the fourth surface 144 is the upper surface of the oil guiding member 140. The third surface 143 of the oil guiding member 140 is in contact with the first surface 131 of the resistive heating element 130.
In this embodiment, the resistive heating element 130 is combined with the atomizing bracket 120, and then the oil guiding member 140 is directly in contact with the resistive heating element 130. In this way, the assembly is simple, and the automatic assembly and production can be realized, which can effectively improve the production efficiency and product stability, and effectively ensure the quality consistency of the atomizing structure. Further, the resistive heating element 130 is in full and close contact with the oil guiding member 140, which can effectively improve the atomization effect and avoid the influence of burning smell to affect the taste of smoking during atomization.
Referring to FIGs. 7-11, specifically, the first surface 131 and the second surface 132 of the resistive heating element 130 are flat surfaces, and the first surface 131 and the second surface 132 are parallel to each other. The oil guiding member 140 has a block structure, the third surface 143 and the fourth surface 144 of the oil guiding member 140 are flat surfaces, and the third surface 143 and the fourth surface 144 are parallel to each other. The oil guiding member 140 can cause the smoke oil to be evenly absorbed and transmitted to the resistive heating element 130, to improve the atomization effect. The oil guiding member 140 may be an oil guide cotton.
A plurality of through holes 133 are provided in the middle of the resistive heating element 130 to form the heating fence 135, so that the resistive heating element 130 forms the first connecting portion 134A, the second connecting portion 134B and the 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 respectively located on two opposite sides of the heating fence 135 along a lengthwise direction of the resistive heating element 130, so that 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 interconnected by the heating fence 135. The heating fence 135 forms a plurality of resistive heating wires 1351 between adjacent through holes 133, and thus the heating fence 135 is the heating part of the resistive heating element 130. The smoke generated by atomization can enter the airflow channel in the atomizer 100 through these through holes 133 and be taken away by the external air entering the atomizer 100 for the user to inhale.
The resistive heating element 130 further includes first and second conductive pins 136A, 136B connected with the first connecting portion 134A and the second connecting portion 134B respectively, wherein each conductive pin 136A/136B is electrically connected with a corresponding connecting portion 134A/134B. In this embodiment, each conductive pin 136A/136B is in the shape of an elongated plate, and each conductive pin 136A/136B is connected with a corresponding connecting portion 134A/134B through a bending portion 139. Each conductive pin 136A/136B and the corresponding connecting portion 134A/134B are separated from each other by the atomizing bracket 120. The two conductive pins 136A, 136B are each located at the lower surface of the atomizing bracket 120 and exposed outside the atomizing bracket 120. The two conductive pins 136A, 136B are each in contact with the lower surface of the atomizing bracket 120.
In this embodiment, the two conductive pins 136A, 136B extend respectively from two opposite ends of the resistive heating element 130 to the outside of the atomizing bracket 120, and are formed by bending downward and inward. Specifically, the two conductive pins 136A, 136B are formed by bending downward and inward from the two connecting portions 134A, 134B, respectively. Each conductive pin 136A/136B is exposed on the lower surface of the atomizing bracket 120, so that it is convenient to realize the electrical connection with the conductive electrode 175 (see FIG. 5) through the exposed conductive pin 136A/136B.
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 with a high thermal decomposition temperature and that is able to tolerate rapid temperature changes. For example, the atomizing bracket 120 may be made of plastic, rubber or silicone. The resistive heating element 130 is combined with the atomizing bracket 120 through an insert molding process. Specifically, when forming 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 is injected into the cavity of the mold, so that the molten plastic, rubber or silicone is coated on the periphery of the resistive heating element 130, and after cooling, the atomizing bracket 120 is formed, so that the resistive heating element 130 is at least partially embedded in the atomizing bracket 120. The bottom surface and outer edges of the first connecting portion 134A and the second connecting portion 134B and the outer edge of the heating fence 135 are integrated with the atomizing bracket 120.
Referring to FIG. 10 and FIG. 11, after the resistive heating element 130 is embedded into the atomizing bracket 120 by insert molding process, two ends of the resistive heating element 130 extend horizontally out of the atomizing bracket 120 (see FIG. 10). Then, a tool (not shown) is used to bend two ends of the resistive heating element 130 downward and inward to form the two conductive pins 136A, 136B (see FIG. 11). The first conductive pin 136A and the second conductive pin 136B are respectively connected with the first connecting portion 134A and the second connecting portion 134B through the bending portions 139, and are located respectively under the first connecting portion 134A and the second connecting portion 134B. Further, the two conductive pins 136A, 136B are exposed to the outside of the atomizing bracket 120. Specifically, each conductive pin 136A/136B is in contact with the lower surface of the bottom plate 121 of the atomizing bracket 120.
In this embodiment, the resistive heating element 130 is combined with the atomizing bracket 120 to form a heating assembly 10.
Referring to FIGs. 7-11, 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 in the atomizing bracket 120. The receiving cavity 123 is surrounded by the bottom plate 121 and the side wall 122 of the atomizing bracket 120, and the upper end of the receiving cavity 123 is formed with an opening 123A. The atomizing opening 126 is arranged in the middle of the bottom plate 121 and penetrates the upper and lower surfaces of the bottom plate 121. The atomizing opening 126 is in communication with the heating fence 135. The heating fence 135 is arranged at the position corresponding to the atomizing opening 126 so that the heating fence 135 is aligned with the atomizing opening 126. The atomizing opening 126 is in communication with the receiving cavity 123. The heating fence 135 is exposed and located above the atomizing opening 126, and the heating fence 135 spans the atomizing opening 126.
In this embodiment, the atomizing opening 126 has a size much smaller than the bottom plate 121, such that the heating fence 135 has a surface area exposed within the receiving cavity 123 larger than another surface area exposed within the atomizing opening 126, or the heating fence 135 has a surface area for contacting the oil guiding member 140 larger than another surface area facing towards the atomizing opening 126.
Referring to FIG. 9 and FIG. 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 specific distance is formed between them, preferably 0.5mm-2.0mm.
The outline of the oil guiding member 140 matches the shape of the receiving cavity 123, and the oil guiding member 140 is placed in the receiving cavity 123 through the opening 123A at the upper end of the receiving cavity 123. The oil guiding member 140 is arranged in the receiving cavity 123 of the atomizing bracket 120 smoothly. The oil guiding member 140 is arranged independently of the atomizing bracket 120 and the resistive heating element 130. The oil guiding member 140 is removably received in the receiving cavity 123, that is, the oil guiding member 140 can be placed into or removed from the receiving cavity 123. The oil guiding 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 resistive heating element 130 and accommodate and support the oil guiding member 140. By limiting the oil guiding member 140 in the receiving cavity 123, the smoke oil absorbed into the receiving cavity 123 through the oil guiding member 140 can only be supplied downward to the resistive heating element 130 for atomization, which can effectively prevent the leakage of the smoke oil and the splashing during atomization.
Referring to FIG. 7 and FIG. 11, the bottom plate 121 of the atomizing bracket 120 includes a bearing surface 124 in contact with the third surface 143 of the oil guiding member 140. Specifically, the bearing surface 124 is the upper surface of the bottom plate 121. The first surface 131 of the resistive heating element 130 is located in the same plane with the upper surface of the bottom plate 121, that is, the upper surface of the heating fence 135 and the upper surface of each connecting portion 134A/134B are located in the same plane with the upper surface of the bottom plate 121. The first surface 131 of the resistive heating element 130 is exposed outside the bottom plate 121 of the atomizing bracket 120, that is, the upper surface of the heating fence 135 and the upper surface of each connecting portion 134A/134B are exposed outside the bottom plate 121 of the atomizing bracket 120. When the oil guiding member 140 is placed in the receiving cavity 123, the third surface 143 of the oil guiding member 140 is in contact with the first surface 131 of the resistive heating element 130 and the upper surface (i.e., the bearing surface 124) of the bottom plate 121, so that the oil guiding member 140 is arranged in the receiving cavity 123 smoothly. Specifically, the third surface 143 of the oil guiding member 140 is in contact with the upper surface of the heating fence 135 and the upper surface of each connecting portion 134A/134B of the resistive heating element 130 and the upper surface (i.e., the bearing surface 124) of the bottom plate 121.
Referring to FIG. 11, each conductive pin 136A, 136B is in contact with the lower surface of the bottom plate 121. Each connecting portion 134A/134B is located on the upper surface of the bottom plate 121, and each connecting portion 134A/134B is located above a corresponding conductive pin 136A/136B. Each connecting portion 134A/134B and the corresponding conductive pin 136A/136B are oppositely arranged on the upper and lower surfaces of the bottom plate 121. Each connecting portion 134A/134B and the corresponding conductive pin 136A/136B are separated from each other by the bottom plate 121 of the atomizing bracket 120, and each connecting portion 134A/134B and the corresponding conductive pin 136A/136B are connected through the bending portion 139. The connecting portions 134A, 134B, the heating fence 135, the conductive pins 136A, 136B and the bending portions 139 are an integral structure.
Referring to FIG. 8 and FIG. 11, the oil guiding member 140 is completely contained in the receiving cavity 123, and the fourth surface 144 of the oil guiding member 140 is lower than the upper surface of the side wall 122 of the atomizing bracket 120, so that a hollow cavity 123B is formed in the atomizing bracket 120 and the hollow cavity 123B is surrounded by the fourth surface 144 of the oil guiding member 140 and the side wall 122 of the atomizing bracket 120.
Referring to FIGs. 2, 3, 5 and 6, the atomizer 100 further includes an oil guiding bracket 150 received in the oil storage container 110.

The lower end of the oil guiding bracket 150 is provided with an annular pressing wall 151, which extends into the hollow cavity 123B and abuts against the periphery of the fourth surface 144 of the oil guiding member 140. A downward pressure is applied to the oil guiding member 140 by the pressing wall 151, so that the oil guiding member 140 is sandwiched between the pressing wall 151 and the bottom plate 121 of the atomizing bracket 120 to prevent the oil guiding member 140 from loosening and displacement, and the oil guiding member 140 can better fit and contact with the resistive heating element 130, so as to improve the atomization effect.
The lower end of the oil guiding bracket 150 is further provided with two baffle plates 152, which are arranged oppositely to each other. The pressing wall 151 is located between the two baffle plates 152 with a gap 153 being formed between the pressing wall 151 and the two baffle plates 152, and the side wall 122 of the atomizing bracket 120 is inserted into the gap 153. By limiting 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.
A sealing pad 181 is further provided in the gap 153, and the sealing pad 181 is sandwiched between the upper surface of the side wall 122 of the atomizing bracket 120 and the lower surface of the oil guiding bracket 150. The sealing pad 181 has a sheet structure, and the middle of the sealing pad 181 is provided with a through hole (not labelled) for the pressing wall 151 to pass through.

The upper end of the oil guiding bracket 150 is provided with two first liquid inlet holes 154 on both sides. The oil storage container 110 is provided with an oil storage chamber 111 for storing smoke oil.

An air outlet channel 113 (see FIG. 6) is formed between the atomizing bracket 120 and the oil storage container 110. The first air outlet hole 155 communicates the air outlet channel 113 with the smoke outlet channel 112, 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 hole 155.
The atomizer 100 further includes a sealing cover 160 received in the oil storage container 110, and the sealing cover 160 is arranged above the oil guiding bracket 150.

The sealing cover 160 is provided with two second liquid inlet holes 162 on both sides corresponding to the two first liquid inlet holes 154. Each second liquid inlet hole 162 communicates the oil storage chamber 111 with a corresponding first liquid inlet hole 154, so that the smoke oil in the oil storage chamber 111 can be transmitted to the oil guiding member 140 through the second liquid inlet holes 162 and the first liquid inlet holes 154 in sequence.
The oil storage container 110 includes an outer tube 114 and an inner tube 115 located in the outer tube 114. The lower end of the outer tube 114 is an open end, and the inner tube 115 is connected with the upper end 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 side wall 163 of the sealing cover 160 is sandwiched between the side wall 156 at the upper end of the oil guiding bracket 150 and the inner wall of the outer tube 114. The lower end of the inner tube 115 is inserted into the second air outlet hole 161, so that the outer wall at the lower end of the inner tube 115 closely abuts against the sealing cover 160 to prevent the smoke oil in the oil storage chamber 111 from leaking.
The atomizer 100 further includes an atomizing base 170 arranged below the atomizing bracket 120 and installed at the 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 inlet hole 173.

The atomizer 100 further includes a sealing ring 182 received in the oil storage container 110. The sealing ring 182 has an annular structure. The sealing 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 the smoke oil from leaking out from the open end at the lower end of the outer tube 114.
The inner surface of the bottom plate 171 of the atomizing base 170 extends upward to provide with two positioning posts 174. The atomizer 100 further includes two conductive electrodes 175.

Referring to FIGs. 9-11, the middle of the bottom plate 121 of the atomizing bracket 120 is penetrated with the atomizing opening 126, the middle of the resistive heating element 130 is provided with a plurality of through holes 133 so as to form the heating fence 135, and the heating fence 135 is in communication with the atomizing opening 126. The smoke generated by atomization can enter the airflow channel in the atomizer 100 through the heating fence 135 and the atomizing opening 126, and is taken away by the external air entering the atomizer 100 for the user to inhale.
When the atomizer 100 works, the smoke oil stored in the oil storage chamber 111 of the oil storage container 110 is guided to the fourth surface 144 of the oil guiding member 140 through the second liquid inlet holes 162 of the sealing cover 160 and the first liquid inlet holes 154 of the oil guiding bracket 150, and then is absorbed by the oil guiding member 140 and transmitted to the third surface 143 which is in close contact with the resistive heating element 130, as shown by the liquid direction arrows in FIG. 5. The resistive heating element 130 generates heat when energized to atomize the smoke oil in contact with the first surface 131 of the resistive heating element 130 to form smoke, and the smoke formed by atomization enters the inner cavity of the atomizing base 170 through the heating fence 135 and the atomizing opening 126. The external air enters the inner cavity of the atomizing base 170 from the air inlet hole 173 of the atomizing base 170, then carries the smoke formed by atomization to flow sequentially through the air outlet channel 113, the first air outlet hole 155, the second air outlet hole 161 and the smoke outlet channel 112, and finally is discharged out for the user to inhale, as shown by the airflow direction arrows in FIG. 6.
In this embodiment, the resistive heating element is combined with the atomizing bracket made by plastic, rubber or silicone to become a heating assembly. Such a heating assembly can realize automatic forming and production through the mold, and after forming, there is no need to go through cumbersome post-processing treatment as required by ceramics, to effectively improve the production efficiency and the product stability, and effectively ensure the quality consistency of the atomizing structure.
In this embodiment, the inner cavity of the heating assembly is installed with an oil guiding member, and the oil guiding bracket is then installed. Under the downward pressure of the oil guiding bracket, the oil guiding member is in close contact with the resistive heating element of the heating assembly, so as to form an atomizing structure with heating capacity and oil guiding channel, thereby effectively improving the atomization effect and avoiding the generation of burning smell to affect the taste of smoking during atomization.
Referring to FIGs. 12-17, another example of the heating assembly in the first embodiment is shown. 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 through the bottom plate 121. The heating fence 135 of the resistive heating element 130 spans 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 includes two inclined portions 1211, the two inclined portions 1211 are located at two opposite sides of the bottom plate 121 along a first direction (e.g., a width direction of the atomizing bracket 120), and 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 the heating assembly 10, the upper surface of the heating fence 135 of and the upper surface of the bottom plate 121 are located in the same plane.

The thickness of the inclined portion 1211 gradually decreases from the side wall 122 to the atomizing opening 126. During injection molding of the inclined portion 1211, because the thickness of the inclined portion 1211 at the side close to the atomizing opening 126 is small, the injection molding material will not flow to the heating fence 135, so as not to pollute the heating fence 135. That is, the edge of the inclined portion 1211 located at the atomizing opening 126 will not form a rough edge of the injection molding material, which can effectively avoid secondary processing (for removing the rough edge) and is conducive to improving the production efficiency, reducing the production cost, and ensuring the high quality and stability of products.
