[0036] This application provides a heating element, including a heating sheet and a fixed seal. The heating sheet is used to generate heat when conducting electricity; the fixed seal is integrally formed with the heating sheet. The fixed seal is provided with a liquid blocking area and a liquid inlet area. The liquid blocking area surrounds the liquid inlet area, and a part of the heating sheet is exposed at a position corresponding to the liquid inlet area.

[0037] For the above-mentioned heating element, the heating sheet and the fixed seal are integrally formed, that is, the heating sheet and the fixed seal are integrated into one component, so that the heating sheet and the fixed seal are fixedly connected, and at the same time, the structure of the heating element is relatively compact, simplifying the structure and assembly process of the heating element; for the heating element of the present invention, the heating sheet and the fixed seal are integrally formed, so that the heating sheet and the fixed seal are reliably fixedly connected, solving the problem of poor assembly reliability of the heating core; the above-mentioned heating element can be assembled on the sealing seat, shortening the liquid guiding path of the sealing seat. Coupled with the fact that the fixed seal is provided with a liquid blocking area and a liquid inlet area, and a part of the heating sheet is exposed at a position corresponding to the liquid inlet area, the atomized liquid can only pass through the liquid inlet area, and at the same time, the heating sheet heats and atomizes the atomized liquid when conducting electricity, realizing reliable liquid guiding while reducing the leakage-proof connection requirement for the connection between the sealing seat and the fixed seat.

[0038] To better understand the technical solutions and beneficial effects of this application, the following further describes this application in detail with specific embodiments:

[0039] As Figure 1 and Figure 2 shown, an atomizer 10 in an embodiment includes a conductive seat 200 and a sealed atomization assembly 100. The sealed atomization assembly 100 includes a sealing seat 110 and a heating element 120. The sealing seat is connected to the conductive seat. The conductive seat is supported by the heating element, and the conductive seat is electrically connected to the heating sheet. Also refer to Figure 4, wherein, the heating element 120 includes a heating sheet 122 and a fixing and sealing member 124. The heating sheet 122 is used to generate heat when conducting electricity. The fixing and sealing member 124 is integrally formed with the heating sheet 122, so that the fixing and sealing member 124 is reliably connected to the heating sheet 122. The fixing and sealing member 124 is connected to the sealing seat 110, so that the heating element is connected to the sealing seat.

[0040] Further, the sealing seat 110 is provided with a liquid passing channel 102. The fixing and sealing member 124 is provided with a liquid blocking area 124a and a liquid inlet area 124b. The liquid blocking area 124a surrounds the liquid inlet area 124b. In this embodiment, the liquid blocking area 124a is arranged at the connecting part of the fixing and sealing member 124 and the sealing seat 110 to prevent the atomized liquid from flowing into the connection part of the fixing and sealing member 124 and the sealing seat 110, playing a role in blocking liquid. Coupled with the fact that the liquid blocking area 124a surrounds the liquid inlet area 124b, the connection part of the fixing and sealing member 124 and the sealing seat 110 can better avoid the situation of atomized liquid leakage. The liquid passing channel is communicated with the liquid inlet area 124b, so that the atomized liquid can flow into the liquid inlet area 124b through the liquid passing channel. Part of the heating sheet 122 is exposed at the position corresponding to the liquid inlet area 124b, so that the heating sheet 122 can heat and atomize the atomized liquid.

[0041] For the above-mentioned heating element 120, the heating sheet 122 and the fixing and sealing member 124 are integrally formed, that is, the heating sheet 122 and the fixing and sealing member 124 are integrated into one component, so that the heating sheet 122 is fixedly connected to the fixing and sealing member 124. At the same time, the structure of the heating element 120 is relatively compact, simplifying the structure and assembly process of the heating element 120; for the heating element 120 of the present invention, the heating sheet 122 and the fixing and sealing member 124 are integrally formed, so that the heating sheet 122 and the fixing and sealing member 124 are reliably fixedly connected, solving the problem of poor assembly reliability of the heating core; for the above-mentioned heating element 120, it can be assembled on the sealing seat 110, shortening the liquid guiding path of the sealing seat 110. Coupled with the fact that the fixing and sealing member 124 is provided with a liquid blocking area 124a and a liquid inlet area 124b, and part of the heating sheet 122 is exposed at the position corresponding to the liquid inlet area 124b, the atomized liquid can only pass through the liquid inlet area 124b. At the same time, the heating sheet 122 heats and atomizes the atomized liquid when conducting electricity, realizing reliable liquid guiding while reducing the leakage prevention connection requirements for the connection between the sealing seat 110 and the fixed seat.

[0042] In this embodiment, the conductive seat 200 is connected to the sealing seat 110. The conductive seat 200 supports the heating element 120, and the conductive seat 200 is electrically connected to the heating sheet 122, so that the heating sheet 122 can reliably heat and atomize the atomized liquid. Since the conductive seat 200 supports the heating element 120, the problem of the separation of the heating element 120 from the sealing seat 110 is avoided, and the heating element 120 is reliably installed on the sealing seat 110.

[0043] As Figures 2 to 4 shown, in one embodiment, the fixed seal 124 and the heating sheet 122 are integrally injection molded, which makes the process of integrally molding the fixed seal 124 and the heating sheet 122 relatively simple. At the same time, the fixed seal 124 and the heating sheet 122 are reliably connected, avoiding the environmental pollution problem existing in forming the heating element 120 by ceramic sintering the heating sheet 122, having good environmental protection, and reducing the processing cost of the heating element 120. In this embodiment, the fixed seal 124 is a high-temperature resistant plastic part or a liquid silicone part, which enables the fixed seal 124 and the heating sheet 122 to be better integrally injection molded.

[0044] As Figure 2 and Figure 4 shown, in one embodiment, the part of the heating sheet 122 exposed in the liquid inlet area 124b is a pore structure, which enables the heating sheet 122 to have a better air passing effect and enables the heating sheet 122 to better heat and atomize the atomized liquid. In this embodiment, the heating sheet 122 is provided with mesh holes, that is, the heating sheet 122 is a heating mesh sheet.

[0045] In one embodiment, the manufacturing method of the heating element 120 includes: first preparing the heating sheet 122; then forming the fixed seal 124 on the heating sheet 122 to integrally mold the fixed seal 124 and the heating sheet 122, thereby enabling the fixed seal 124 and the heating sheet 122 to be reliably connected, and at the same time making the structure of the heating element 120 more compact.

[0046] Further, the step of preparing the heating sheet 122 is specifically: forming the heating sheet 122 by stamping, which makes the processing difficulty of the heating sheet 122 relatively low and makes the structure of the heating sheet 122 relatively compact. Further, the heating sheet 122 is a mesh hole metal sheet structure, which enables the heating sheet 122 to better heat and atomize the atomized liquid, and the atomized vapor generated by heating and atomizing flows out through the mesh holes, improving the atomization effect of the atomizer 10.

[0047] Further, the step of forming the fixed seal 124 on the heating sheet 122 includes: first placing the fixed seal 124 in an injection mold; then pouring injection slurry into the injection mold; then performing a curing treatment, so that the periphery of the heating sheet 122 is coated with the fixed seal 124, the fixed seal 124 forms a liquid blocking area 124a and a liquid inlet area 124b, the liquid blocking area 124a is arranged around the liquid inlet area 124b, and a part of the heating sheet 122 is exposed at a position corresponding to the liquid inlet area 124b.

[0048] To enable the fixed seal 124 to be reliably injection-molded onto the heating sheet 122, in one embodiment, the steps of the curing process are specifically as follows: First, cool the injection slurry in the injection mold; then let it stand for a predetermined time to enable the fixed seal 124 to be reliably injection-molded onto the heating sheet 122.

[0049] As Figure 4 and Figure 5 shown, in one embodiment, the seal seat 110 is further provided with a receiving groove 104 communicating with the liquid passage 102. The fixed seal 124 is located in the receiving groove 104 and is tightly connected to the seal seat 110, so that the atomized liquid flows into the receiving groove 104 through the liquid passage 102. Since the liquid passage communicates with the liquid inlet area 124b, the fixed seal 124 is located in the receiving groove 104 and is tightly connected to the seal seat 110, enabling the heating element to be reliably mounted on the seal seat 110. At the same time, the atomized liquid reliably flows into the liquid inlet area 124b to contact the heating sheet, achieving reliable heating and atomization. In this embodiment, the heating element 120 is mounted and fixed to the seal seat 110 through the receiving groove 104, so that the heating element 120 is mounted on the seal seat 110 instead of on the conductive seat 200, greatly simplifying the structure of the conductive seat 200 and making the structure of the atomizer 10 more compact.

[0050] As Figure 4 shown, in one embodiment, the heating element 120 further includes a sealing ring 126. An annular groove 124c is formed in the outer peripheral wall of the fixed seal 124. The sealing ring 126 is disposed in the annular groove 124c and surrounds the liquid blocking area 124a, so that the fixed seal 124 is tightly connected to the seal seat 110, further avoiding the problem of leakage of the atomized liquid from the connection between the fixed seal 124 and the seal seat 110. In this embodiment, the sealing ring 126 protrudes from the annular groove 124c and elastically abuts against the inner wall of the receiving groove 104, so that the fixed seal 124 is tightly connected to the seal seat 110. Further, the sealing ring 126 is a silicone ring, so that the sealing ring 126 has good elasticity and sealing performance.

[0051] It can be understood that in other embodiments, the sealing ring 126 can be omitted. As Figures 6 to 8As shown, in one embodiment, the fixed seal 124 is located within the receiving groove 104 and is elastically connected to the seal seat 110, such that the fixed seal 124 is tightly connected to the seal seat 110. In this embodiment, the fixed seal 124 is a silicone member, and an annular flange 1242 is provided on the outer peripheral wall of the fixed seal 124. The annular flange 1242 is elastically abutted against the inner wall of the receiving groove 104, such that the fixed seal 124 is tightly connected to the seal seat 110. Specifically, the number of abutting flanges is two, and the two abutting flanges are arranged side by side, such that the fixed seal 124 is tightly connected to the seal seat 110.

[0052] As Figure 4 or Figure 8 shown, in one of the embodiments, the liquid inlet area 124b is a groove structure. A liquid guiding inclined surface 1244 is provided on the inner wall of the liquid inlet area 124b adjacent to the liquid passing channel 102, such that the atomized liquid reliably flows in through the guiding action of the liquid guiding inclined surface 1244 and contacts the heating sheet 122, and further enables the heating sheet 122 to better heat and atomize the atomized liquid.

[0053] As Figure 2 and Figure 4 shown, in one of the embodiments, the sealed atomization assembly 100 further includes a liquid guiding member 130. The liquid guiding member 130 is disposed in the liquid inlet area 124b. The liquid guiding member 130 is respectively abutted against the heating sheet 122 and the inner wall of the receiving groove 104, such that the liquid guiding member 130 and the heating member 120 are assembled together in the receiving groove 104 of the seal seat 110. Since the liquid guiding member 130 is respectively abutted against the heating sheet 122 and the inner wall of the receiving groove 104, the liquid guiding member 130 is tightly abutted against the heating sheet 122. Further, the heating sheet 122 heats and atomizes the liquid guiding member 130. At the same time, the liquid guiding member 130 functions to guide and stabilize the liquid, such that the atomized vapor generated by the heating sheet 122 heating the liquid guiding member 130 is relatively uniform, and at the same time, the situation of the heating sheet 122 being dry burned is avoided. In this embodiment, the liquid guiding member 130 is a liquid guiding cotton block, such that the liquid guiding member 130 has a good liquid guiding and stabilizing effect, and at the same time, the liquid guiding member 130 better elastically abuts against the heating sheet 122. The liquid inlet area 124b is a groove structure, and the liquid guiding member 130 is located in the liquid inlet area 124b and is connected to the fixed seal 124.

[0054] As Figure 8As shown, further, the liquid guide member 130 is in interference fit with the fixed seal member 124, so that the liquid guide member 130 is elastically connected to the inner peripheral wall of the liquid inlet area 124b, and further, the liquid guide member 130 is reliably connected to the fixed seal member 124. In this embodiment, a liquid guide inclined surface 1244 is provided on the inner wall of the liquid passing channel 102 adjacent to the liquid inlet area 124b, so that the atomized liquid flowing out through the liquid passing channel 102 can quickly flow into the liquid guide member 130 under the guiding action of the liquid guide inclined surface 1244, realizing better guiding of the atomized liquid into the liquid guide member 130. Further, the inclination angle of the liquid guide inclined surface 1244 is 10 degrees to 40 degrees, so that the liquid guide inclined surface 1244 guides the atomized liquid into the liquid inlet area 124b. In this embodiment, the inclination angle of the liquid guide inclined surface 1244 is 15 degrees.

[0055] As Figure 2 , Figure 9 and Figure 10 As shown, in one embodiment, the conductive base 200 includes a conductive base body 210, a first conductive column 220 and a second conductive column 230. The conductive base body 210 is connected to the seal base 110. The conductive base body 210 is provided with a first fixing hole 202 and a second fixing hole 204. The first conductive column 220 is inserted into the first fixing hole 202 and connected to the conductive base body 210. The second conductive column 230 is inserted into the second fixing hole 204 and connected to the conductive base body 210, so that both the first conductive column 220 and the second conductive column 230 are installed and fixed on the conductive base body 210. Both the first conductive column 220 and the second conductive column 230 abut against and support the heating element 120, and at the same time, both the first conductive column 220 and the second conductive column 230 are electrically connected to the heating sheet 122. Specifically, the heating sheet 122 is a heating mesh sheet, and the heating sheet 122 is integrally injection-molded with the sealing and fixing member. The liquid guide member 130 is placed on the heating sheet 122 and tightly fixed in the receiving groove 104. The first conductive column 220 and the second conductive column 230 respectively abut against both sides of the heating sheet 122 to make the heating sheet 122 conductive. Since the liquid guide member 130 is a liquid guide cotton member, i.e., an oil absorption cotton, the liquid guide member 130 can reliably guide and stabilize the liquid, solving the problem of abnormal taste caused by unsmooth ceramic oil guiding.

[0056] For the convenience of maintaining or cleaning the atomizer 10, as Figure 2 , Figure 9 and Figure 10As shown, further, the conductive base body 210 is detachably connected to the sealing base 110 so as to maintain or clean the atomizer 10. In this embodiment, the conductive base body 210 is snap-connected to the sealing base 110 to achieve quick disassembly and assembly of the conductive base body 210 and the sealing base 110. Specifically, the conductive base body 210 is provided with a clamping groove 219, and a clamping hook 114 protrudes from the outer peripheral wall of the sealing base 110. The clamping hook 114 is snapped into the clamping groove 219 to snap-connect the conductive base body 210 and the sealing base 110. It can be understood that in other embodiments, the installation positions of the clamping groove 219 and the clamping hook 114 can be interchanged. Of course, in other embodiments, the conductive base body 210 and the sealing base 110 are not limited to snap connection only.

[0057] As Figure 2 , Figure 9 and Figure 10 As shown, further, an atomization chamber 300 is formed between the conductive base body 210 and the sealing base 110. The atomization chamber 300 is correspondingly arranged with the heating sheet 122, so that the atomized vapor generated when the heating sheet 122 heats and atomizes the liquid can quickly flow into the atomization chamber 300, improving the atomization efficiency. The conductive base body 210 is provided with an air inlet hole 212, and the air inlet hole 212 is communicated with the atomization chamber 300, so that the peripheral air flow quickly flows into the atomization chamber 300 through the air inlet hole 212 and mixes with the atomized vapor to form atomized gas.

[0058] As Figure 5 As shown, further, the fixed seal 124 is formed with a first exposed hole 1241 and a second exposed hole 1243. Both the first exposed hole 1241 and the second exposed hole 1243 are communicated with the liquid inlet area 124b. The heating sheet 122 is respectively exposed in the first exposed hole 1241 and the second exposed hole 1243, and the first conductive column 220 abuts against the heating sheet 122 through the first exposed hole 1241, and the second conductive column 230 abuts against the heating sheet 122 through the second exposed hole 1243, so that both the first conductive column 220 and the second conductive column 230 are electrically connected to the heating sheet 122. At the same time, the positions of the first conductive column 220 and the second conductive column 230 installed on the conductive base 200 can be staggered from the liquid inlet area 124b, so that the surface area of the atomized vapor generated by the heating sheet 122 heating and atomizing the liquid is larger, thereby improving the atomization effect of the atomizer 10.

[0059] As Figure 2 , Figure 10 and Figure 11As shown, in one embodiment, the atomizer 10 further includes an oil cup member 400. An oil storage cavity 402 is formed in the oil cup member 400. A central tube 404 protrudes from the inner wall of the oil storage cavity 402. The sealing seat 110 is located in the oil storage cavity 402 and is tightly connected to the oil cup member 400. The sealing seat 110 is sleeved on the central tube 404. An overflow hole 111 is formed on the side wall of the sealing seat 110. The atomization cavity 300 is communicated with the central tube 404 through the overflow hole 111, realizing reliable air guiding of the atomizer 10. Since the overflow hole 111 is opened on the side wall of the sealing seat 110, the structure of the sealing seat 110 is more compact. In this embodiment, the overflow hole 111 is opened on one side of the sealing seat 110, and the overflow hole 111 is communicated with the atomization cavity 300.

[0060] To enable both the first conductive post 220 and the second conductive post 230 to reliably support and abut against the sealing seat 110, as Figure 6 shown, further, the oil cup member 400 is sleeved on the conductive seat body 210, so that the oil cup member 400 is fixedly connected to the conductive seat body 210. Since the conductive seat body 210 is also connected to the sealing seat 110, and the sealing seat 110 is tightly connected to the oil cup member 400, both the first conductive post 220 and the second conductive post 230 can reliably support and abut against the sealing seat 110. To enable the oil cup member 400 to be detachably connected to the conductive seat body 210, further, as Figure 10 and Figure 11 shown, a clamping protrusion 211 protrudes from the outer peripheral wall of the conductive seat body 210. A connecting groove 406 is formed in the inner wall of the oil cup member 400. The clamping protrusion 211 is located in the connecting groove 406 and is snap-connected to the oil cup member 400, realizing the detachable connection between the conductive seat body 210 and the oil cup member 400, and at the same time enabling the quick disassembly and assembly of the conductive seat body 210 and the oil cup member 400.

[0061] As Figure 5 and Figure 7 shown, further, the projection position of the air inlet hole 212 on the sealing seat 110 is adjacent to the side away from the overflow hole 111 opened on the sealing seat 110. The peripheral air flow first flows into the atomization cavity 300 through the air inlet hole 212 and mixes with the atomized vapor to form atomized gas. The atomized gas flows out of the atomization cavity 300 through the overflow hole 111, so that the path of the air flow is longer and the contact area with the heating sheet 122 is larger, thus better forming atomized gas. In this embodiment, the air inlet hole 212 is arranged to avoid the pores of the heating sheet 122, preventing the condensate generated by the heating and atomization of the heating sheet 122 from flowing out through the air inlet hole 212, that is, avoiding the problem of liquid leakage of the atomizer 10. To better avoid the problem of liquid leakage of the atomizer 10, as Figure 2 and Figure 10As shown, further, a liquid collecting groove 213 is formed at a position of the conductive base body 210 corresponding to the heating sheet 122. The liquid collecting groove 213 is used for collecting condensed liquid. The height position of the notch of the liquid collecting groove 213 is lower than that of the notch of the air inlet hole 212, so that the condensed liquid generated when the heating sheet 122 is heating directly drips into the liquid collecting groove 213, realizing the collection of the condensed liquid. Coupled with the fact that the height position of the notch of the liquid collecting groove 213 is lower than that of the notch of the air inlet hole 212, the problem of liquid leakage of the atomizer 10 is better avoided.

[0062] As Figure 2 shown, further, a first avoidance notch 215 and a second avoidance notch 217 are respectively formed on two sides of the conductive base body 210. Both the first avoidance notch 215 and the second avoidance notch 217 communicate with the atomization chamber 300. A part of the sealing seat 110 is located in the first avoidance notch 215 and the second avoidance notch 217, and the sealing seat 110 is connected to the conductive seat 200. The first avoidance notch 215 also communicates with the current-limiting hole 111, so that the atomized gas in the atomization chamber 300 is communicated with the current-limiting hole 111 through the first avoidance notch 215, enabling the atomized gas in the atomization chamber 300 to quickly flow into the current-limiting hole 111. At the same time, the connection between the sealing seat 110 and the conductive seat 200 is made simpler, and the structure of the conductive seat 200 is made simpler.

[0063] To enable the sealing seat 110 to be quickly and snap-connected to the conductive seat 200 in place, and at the same time make the connection between the sealing seat 110 and the conductive seat 200 more reliable, as Figure 2 shown, even further, a sliding guide groove 218 is also formed on the conductive base body 210. The sliding guide groove 218 communicates with the clamping groove 219. A guiding sliding wall 113 is formed on the side wall of the sealing seat 110, and a hook 114 protrudes from the surface of the guiding sliding wall 113. A sliding guide post is located in the sliding guide groove 218 and is slidably connected to the conductive base body 210. Under the guiding effect of the sliding fit between the sliding guide groove 218 and the guiding sliding wall 113, the sealing seat 110 is quickly and snap-connected to the conductive seat 200 in place, and at the same time the connection between the sealing seat 110 and the conductive seat 200 is made more reliable.

[0064] As Figure 2 shown, further, the atomizer 10 further includes a connecting convex ring 500. A sealing ring groove 215 is formed on the outer peripheral wall of the conductive base body 210. The connecting convex ring 500 protrudes into the sealing ring groove 215, and the connecting convex ring 500 elastically abuts against the inner peripheral wall of the oil cup member 400. In this embodiment, the connecting convex rings 500 are respectively arranged below the first avoidance notch 215 and the second avoidance notch 217, and the connecting convex rings 500 are located above the clamping protrusions 211, avoiding the problems of air leakage or liquid leakage of the atomizer 10. The conductive base body 210 is tightly connected to the oil cup member 400.

[0065] The present application also provides an electronic atomization device, including the atomizer 10 described in any of the above embodiments.

[0066] Compared with the prior art, the present invention has at least the following advantages:

[0067] 1. In the heating element 120 of the present invention, the heating sheet 122 and the fixed seal 124 are integrally formed, that is, the heating sheet 122 and the fixed seal 124 are integrated into one component, so that the heating sheet 122 and the fixed seal 124 are fixedly connected, and at the same time, the structure of the heating element 120 is relatively compact, simplifying the structure and assembly process of the heating element 120;

[0068] 2. In the heating element 120 of the present invention, the heating sheet 122 and the fixed seal 124 are integrally formed, so that the heating sheet 122 and the fixed seal 124 are reliably fixedly connected, solving the problem of poor assembly reliability of the heating core;

[0069] 3. The above-mentioned heating element 120 can be assembled on the sealing seat 110, shortening the liquid guiding path of the sealing seat 110. In addition, the fixed seal 124 is provided with a liquid blocking area 124a and a liquid inlet area 124b, and part of the heating sheet 122 is exposed at the position corresponding to the liquid inlet area 124b, so that the atomization liquid can only pass through the liquid inlet area 124b, and at the same time, the heating sheet 122 heats and atomizes the atomization liquid when conducting electricity, reducing the leakage prevention connection requirement for the connection between the sealing seat 110 and the fixed seat while realizing reliable liquid guiding.

[0070] The above embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent.
