Description

Technical Field

[0001] The present invention relates to the technical field of electronic atomization, and particularly to an atomization core structure, an atomizer and an electronic atomization device. Background Art

[0002] Traditional atomizers include an oil cup and an atomization core. The atomization liquid such as e-liquid in the oil storage cavity of the oil cup flows into the atomization cavity through the oil inlet hole of the central tube, so that the atomization liquid is heated and atomized by the atomization core in the central tube. To save transportation costs, before transportation, the e-liquid is pre-injected into the oil cup, and the atomization cavity is separated from the oil storage cavity by setting a sealing protective film to prevent the e-liquid from contacting the atomization core for a long time during the transportation of the oil cup, resulting in oxidation or even oil leakage. During use, only need to puncture the sealing protective film to make the e-liquid leak out to the atomization core for heating and atomization.

[0003] However, since the atomization core is integrally fixed in the oil cup component, when the atomization liquid in the oil storage cavity is used up, the whole atomizer is discarded together.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0033] The present application provides an atomizing core structure for detachably connecting with an oil cup assembly. The atomizing core structure includes a fixed seat and an atomizing push rod assembly; the fixed seat is used for detachably connecting to the oil cup assembly; the atomizing push rod assembly includes a push rod assembly and an atomizing assembly. The push rod assembly is connected to the fixed seat. The push rod assembly is provided with an air inlet hole, an atomizing channel and an oil passing hole. The air inlet hole and the oil passing hole are both communicated with the atomizing channel. The atomizing assembly is arranged in the atomizing channel and the atomizing assembly is correspondingly arranged with the oil passing hole; the push rod assembly is used for pushing the movable rod of the oil cup assembly to a predetermined position during use so that the oil storage cavity of the oil cup part of the oil cup assembly is communicated with the oil passing hole.

[0034] For the atomizing core structure described above, the push rod assembly is used to push the movable rod of the oil cup assembly to a predetermined position when the fixed seat is connected to the oil cup assembly, so that the oil storage cavity of the oil cup part of the oil cup assembly communicates with the oil passing hole, and the atomizing liquid in the oil storage cavity flows into the atomizing channel through the oil passing hole. Since the atomizing assembly is arranged in the atomizing channel and is correspondingly arranged with the oil passing hole, the atomizing assembly heats and atomizes the atomizing liquid. Before use, such as during transportation, since the oil passing hole is not communicated with the oil storage cavity, it avoids the problem of premature contact between the atomizing liquid in the oil storage cavity of the oil cup assembly and the atomizing assembly and oxidation, and at the same time can achieve reliable sealing of the oil cup assembly. Since the fixed seat is detachably connected to the oil cup assembly, the push rod assembly is connected to the fixed seat, and since the push rod assembly is provided with an atomizing channel and the atomizing assembly is arranged in the atomizing channel, that is, the atomizing assembly is assembled in the atomizing channel, thus the atomizing push rod integrated part is connected to the fixed seat. When the atomizing liquid in the oil cup assembly is used up, the fixed seat is removed from the oil cup assembly and assembled with a new oil cup assembly for use, realizing the reuse of the atomizing core structure. And the oil cup assembly is a simple accessory without an atomizing core structure. When the atomizing liquid in the oil cup assembly is used up, it can be directly discarded with less environmental pollution, solving the problem of poor environmental protection of the atomizer.

[0035] To better understand the technical solution and beneficial effects of the present application, the following further describes the present application in detail with specific embodiments:

[0036] As Figures 1 to 3 shown, an atomizer 10 in an embodiment includes an oil cup assembly 100 and an atomizing core structure 200, and the atomizing core structure 200 is detachably connected to the oil cup assembly 100. The oil cup assembly 100 includes an oil cup part 110, a movable rod 120, and a sealing member 130. The oil cup part 110 forms an oil storage cavity 101 and an air outlet hole 103. The movable rod 120 is movably connected to the oil cup part 110, and the oil storage cavity 101 is separated from the air outlet hole 103 by the movable rod 120, and the movable rod 120 communicates with the air outlet hole 103. The sealing member 130 is located in the oil storage cavity 101 and is tightly connected to the oil cup part 110, and the sealing member 130 is sleeved on the movable rod 120 and is movably connected to the movable rod 120. Since the sealing member 130 is also movably connected to the oil cup part 110, the positions where the movable rod 120 is connected to the sealing member 130 and the oil cup part 110 are adjustable.

[0037] As Figures 1 to 3As shown, further, the atomizing core structure 200 includes a fixing base 210 and an atomizing push rod assembly 220. The fixing base 210 is detachably connected to the oil cup assembly 100, so that the atomizing core structure 200 is detachably connected to the oil cup assembly 100. The atomizing push rod assembly 220 includes a push rod assembly 222 and an atomizing assembly 224. The push rod assembly 222 is connected to the fixing base 210, so that the atomizing push rod assembly 220 is connected to the fixing base 210. Further, the push rod assembly 222 is provided with an air inlet hole 201, an atomizing channel 203 and an oil passing hole 205. The atomizing channel 203 is communicated with the air outlet hole 103. The fixing base 210 abuts against the sealing member 130 to reliably limit the sealing member 130 in the oil storage cavity 101.

[0038] As Figure 2 and Figure 3 shown, the movable rod 120 is provided with an oil inlet hole 105. The atomizing assembly 224 is disposed in the atomizing channel 203, and the atomizing assembly 224 is correspondingly disposed with the oil passing hole 205. The push rod assembly 222 is used to push the movable rod 120 of the oil cup assembly 100 to a predetermined position during use, that is, to push the movable rod 120 to move relative to the sealing member 130 and the oil cup member 110 to a predetermined position during use, so that the oil storage cavity 101 of the oil cup member 110 of the oil cup assembly 100 is communicated with the oil passing hole 205. In this embodiment, the push rod assembly 222 is inserted into the movable rod 120, and the atomizing channel 203 is communicated with the movable rod 120. It can be understood that, as Figure 2 shown, before use, such as during transportation, the movable rod 120 is respectively connected to the sealing member 130 and the oil cup member 110. At this time, the movable rod 120 is respectively in an initial position relative to the sealing member 130 and the oil cup member 110, that is, at this time, the sealing member 130 is sleeved on the part of the movable rod 120 where the oil inlet hole 105 is opened, so that the oil inlet hole 105 is blocked in the sealing member 130, that is, the oil inlet hole 105 is not communicated with the oil storage cavity 101. At this time, the atomizing liquid cannot flow out of the oil storage cavity 101, and the atomizing liquid is reliably stored in the oil storage cavity 101. As Figure 3As shown, when in use, the fixed seat 210 is respectively connected to the oil cup assembly 100 and the fixed seat 210. The push rod assembly 222 is used to push the movable rod 120 of the oil cup assembly 100 to move relative to the seal 130 and the oil cup member 110 respectively, so that the movable rod 120 moves relative to the seal 130 and the oil cup member 110 respectively until the movable rod 120 is in a predetermined position relative to the seal 130 and the oil cup member 110. At this time, the oil inlet hole 105 is communicated with the oil storage cavity 101, that is, the oil storage cavity 101 is communicated with the atomization channel 203 through the oil passing hole 205. The air inlet hole 201 and the oil passing hole 205 are both communicated with the atomization channel 203, so that the atomized liquid in the oil storage cavity 101 flows into the atomization channel 203 through the oil passing hole 205 and is heated and atomized by the atomization assembly 224.

[0039] For the above atomization core structure 200, the push rod assembly 222 is used to push the movable rod 120 of the oil cup assembly 100 to move to a predetermined position when the fixed seat 210 is connected to the oil cup assembly 100, so that the oil storage cavity 101 of the oil cup member 110 of the oil cup assembly 100 is communicated with the oil passing hole 205, and the atomized liquid in the oil storage cavity 101 flows into the atomization channel 203 through the oil passing hole 205. Since the atomization assembly 224 is arranged in the atomization channel 203 and the atomization assembly 224 is arranged corresponding to the oil passing hole 205, the atomization assembly 224 heats and atomizes the atomized liquid; before use, such as during transportation, since the oil passing hole 205 is not communicated with the oil storage cavity 101, the problem that the atomized liquid in the oil storage cavity 101 of the oil cup assembly 100 contacts the atomization assembly 224 in advance and is oxidized is avoided, and at the same time, reliable sealing of the oil cup assembly 100 can be achieved; since the fixed seat 210 is detachably connected to the oil cup assembly 100, the push rod assembly 222 is connected to the fixed seat 210, and since the push rod assembly 222 is provided with the atomization channel 203 and the atomization assembly 224 is arranged in the atomization channel 203, that is, the atomization assembly 224 is assembled in the atomization channel 203, so that the atomization push rod integrated part 220 is connected to the fixed seat 210. When the atomized liquid in the oil cup assembly 100 is used up, the fixed seat 210 is removed from the oil cup assembly 100 and assembled with a new oil cup assembly 100 for use, realizing the repeated use of the atomization core structure 200. The oil cup assembly 100 is a simple accessory without the atomization core structure 200. When the atomized liquid in the oil cup assembly 100 is used up, it can be directly discarded with less environmental pollution, solving the problem of poor environmental protection of the atomizer 10.

[0040] Such as Figure 2As shown, in one embodiment, the push rod assembly 222 includes a push rod member 222a and a sliding member 222b. The sliding member 222b is used to be inserted into the movable rod member 120 and push the movable rod member 120 to slide. The oil passage hole 205 is formed in the sliding member 222b, so that the push rod assembly 222 is provided with the oil passage hole 205. The push rod member 222a is sleeved on the sliding member 222b, and the push rod member 222a abuts against the sliding member 222b, so that the push rod assembly 222 can push the movable rod member 120 to move relative to the seal member 130 and the oil cup member 110 respectively during use, and at the same time, the push rod member 222a and the sliding member 222b are reliably connected. Also refer to Figure 3 , the atomization channel 203 includes an air intake channel 203a formed in the push rod member 222a and a flow-through channel 203b formed in the sliding member 222b. The air intake channel 203a is communicated with the flow-through channel 203b, and the flow-through channel 203b is communicated with the oil passage hole 205, so that the oil passage hole 205 is communicated with the atomization channel 203. The atomization core assembly is located in the flow-through channel 203b and is tightly connected to the sliding member 222b, that is, the atomization assembly 224 is located in the flow-through channel 203b and is tightly connected to the sliding member 222b, so that the atomization liquid flowing in through the oil passage hole 205 can reliably contact the atomization core assembly, and further the atomization core assembly can reliably heat and atomize the atomization liquid to generate atomized vapor, while avoiding the problem of atomization liquid leakage in the atomization channel 203. The air intake channel 203a is communicated with the air intake hole 201, so that the air intake hole 201 is communicated with the atomization channel 203, and further the air flow outside the atomizer 10 can flow into the atomization channel 203 through the air intake hole 201 to be mixed with the atomized vapor to form atomized gas. Since the push rod member 222a and the sliding member 222b are two independent components, during assembly, the atomization core assembly can be first assembled in the flow-through channel 203b and tightly connected to the sliding member 222b, and then the push rod member 222a is assembled and connected to the sliding member 222b, which improves the convenience of use of the atomization core structure 200. It can be understood that in other embodiments, the connection manner between the push rod member 222a and the sliding member 222b is not limited to the push rod member 222a being sleeved on the sliding member 222b. For example, the connection manner between the push rod member 222a and the sliding member 222b is that the sliding member 222b is sleeved on the push rod member 222a. Or, one end of the push rod member 222a is connected to one end of the sliding member 222b. Specifically, one end of the push rod member 222a is welded or glued to one end of the sliding member 222b. In other embodiments, the movable rod member 120 is not limited to being slidably connected to the oil cup member 110 and the seal member 130 respectively. For example, the movable rod member 120 is respectively rotatably connected to the oil cup member 110 and the seal member 130.

[0041] As Figures 2 to 3As shown, in one embodiment, a connecting portion 101a is convexly provided on the inner wall of the oil storage chamber 101, and the connecting portion 101a is arranged around the air outlet hole 103. The movable rod member 120 is sleeved with the connecting portion 101a, and the movable rod member 120 is movably connected to the connecting portion 101a. In this embodiment, the connecting portion 101a is convexly provided on the inner wall of the oil storage chamber 101, the connecting portion 101a is arranged around the air outlet hole 103, the connecting portion 101a is sleeved on the movable rod member 120 and is slidably connected to the movable rod member 120. In one of the embodiments, the connecting portion 101a includes an annular convex edge 1012 and a connecting convex edge 1014, the annular convex edge 1012 is arranged around the connecting convex edge 1014, and the connecting convex edge 1014 is arranged around the air outlet hole 103. A connecting gap 1013 exists between the annular convex edge 1012 and the connecting convex edge 1014. One end of the movable rod member 120 is located in the connecting gap 1013, and the movable rod member 120 is sleeved on the connecting convex edge 1014 and is slidably connected to the connecting convex edge 1014, so that the movable rod member 120 is reliably connected to the connecting portion 101a.

[0042] As Figures 2 to 3 shown, in one of the embodiments, the oil cup assembly 100 further includes a sliding fit member 140. The sliding fit member 140 is partially located in the connecting gap 1013, and the sliding fit member 140 is sleeved on the movable rod member 120, so that the movable rod member 120 is tightly connected to the connecting portion 101a through the sliding fit member 140, and further the movable rod member 120 is more reliably connected to the connecting portion 101a. In this embodiment, the sliding fit member 140 can be a silicone member or a rubber member, so that the sliding fit member 140 has good elasticity, and at the same time the movable rod member 120 is tightly fitted with the inner wall of the connecting gap 1013, improving the sealing performance between the connection of the movable rod member 120 and the connecting portion 101a.

[0043] As Figures 2 to 3As shown, in one embodiment, the sliding fitting 140 includes a sliding fitting portion 142 and a limiting portion 144, and the sliding fitting portion 142 is connected to the limiting portion 144. The sliding fitting portion 142 is located within the connection gap 1013 and sleeved on the movable rod 120, and the limiting portion 144 is clamped to the annular convex edge 1012 to prevent the sliding fitting portion 142 from sliding into the connection gap 1013 along with the movable rod 120 during the sliding of the movable rod 120 relative to the connecting portion 101a, which may affect the sealing performance of the connecting portion 101a, so that the sliding fitting 140 is reliably limited within the connecting portion 101a, and further the movable rod 120 is reliably and tightly connected to the connecting portion 101a through the sliding fitting 140. In this embodiment, the sliding fitting portion 142 and the limiting portion 144 are of an integrally formed structure, which enables the sliding fitting portion 142 to be reliably connected to the limiting portion 144 and at the same time makes the structure of the sliding fitting 140 more compact. Specifically, the sliding fitting 140 is an integrally formed silicone part, which enables the sliding fitting 140 to have better elasticity. It can be understood that in other embodiments, the sliding fitting portion 142 and the limiting portion 144 are formed separately, and the sliding fitting portion 142 is connected to the limiting portion 144 integrally by gluing or welding.

[0044] To enable the sliding fitting to be closely fitted with the movable rod 120, as Figures 2 to 3 shown, further, a sliding flange 142a is provided on the inner wall of the sliding fitting portion 142, and the sliding flange elastically abuts against the outer peripheral wall of the movable rod 120, so that the movable fitting portion is reliably and movably and closely fitted and connected with the movable rod 120. In this embodiment, the number of sliding flanges is multiple, and the multiple sliding flanges are spaced apart along the sliding direction of the movable rod 120, and the multiple sliding flanges all elastically abut against the movable rod 120, so that the movable rod 120 is better closely and slidably connected with the sliding fitting.

[0045] As Figures 2 to 3As shown, in one embodiment, the seal 130 is provided with an insertion and extraction hole 131. The movable rod 120 passes through the insertion and extraction hole and is tightly and movably connected to the seal 130, improving the sealing performance during the relative movement between the movable rod 120 and the seal 130. In this embodiment, the seal 130 is a silicone part, making the seal 130 have good elasticity. Furthermore, the seal 130 is tightly and elastically connected to the inner wall of the oil cup part 110, and at the same time, the seal 130 is elastically connected to the movable rod 120. Further, at least one annular flange 131a is formed on the inner wall of the insertion and extraction hole. The annular flange is in a tight fit with the movable rod 120, causing the annular flange to undergo elastic deformation when the movable rod 120 is inserted and extracted with the insertion and extraction hole, and further enabling the movable rod 120 to be more tightly and movably connected to the seal 130. In this embodiment, the number of annular flanges is multiple, and the multiple annular flanges are arranged at intervals, further enabling the movable rod 120 to be more tightly and movably connected to the seal 130.

[0046] To further improve the sealing reliability of the connection between the seal 130 and the movable rod 120 and avoid the problem of slight leakage of the atomized liquid from the annular flange due to repeated insertion and extraction or manufacturing deviation, further, an annular embedding groove is formed on the inner wall of the insertion and extraction hole. The oil cup assembly 100 further includes an oil retaining ring part. The oil retaining ring part is embedded in the annular embedding groove, and the oil retaining ring part elastically abuts against the movable rod 120. The multiple annular flanges are arranged at intervals along the center of the insertion and extraction hole. Among them, the annular flange adjacent to the oil storage cavity 101 is the first annular flange, and the annular flange adjacent to the first annular flange is the second annular flange. The oil retaining ring part is arranged between the first annular flange and the second annular flange, enabling the first annular flange, the second annular flange, and the oil retaining ring part to jointly elastically abut against the movable rod 120, avoiding the problem of slight leakage of the atomized liquid from the annular flange due to repeated insertion and extraction or manufacturing deviation, and further improving the sealing reliability of the connection between the seal 130 and the movable rod 120. In this embodiment, the oil retaining ring part is a silicone ring part.

[0047] To improve the convenience of assembling the seal 130 to the oil cup part 110 and at the same time facilitate the reliable injection of the atomized liquid into the oil storage cavity 101, such as Figures 2 to 3As shown, further, the seal 130 includes a seal body 132 and an oil retaining plug 134. The seal body 132 is located in the oil storage cavity 101 and is tightly connected to the oil cup member 110. The seal body 132 is formed with an oil injection hole 132a which communicates with the oil storage cavity 101. The oil retaining plug 134 is located in the oil injection hole 132a and is tightly connected to the seal body 132. During assembly, the seal body 132 can be first assembled to the oil cup member 110, and at the same time, the seal body 132 is sleeved on the movable rod member 120. Then, the atomized liquid is injected into the oil storage cavity 101 through the oil injection hole 132a. Finally, the oil retaining plug 134 is inserted into the oil injection hole 132a, which improves the convenience of assembling the seal 130 to the oil cup member 110. At the same time, it is convenient for the atomized liquid to be reliably injected into the oil storage cavity 101, and the situation that the atomized liquid leaks from the connection between the seal body 132 and the oil cup member 110 is avoided. In this embodiment, the seal body 132 is a silica gel plug, which enables the seal body 132 to better elastically abut against the oil cup member 110.

[0048] As Figures 2 to 3 shown, in one embodiment, the push rod member 222a is detachably connected to the sliding member 222b, which improves the convenience of connecting the push rod member 222a and the sliding member 222b. In this embodiment, the push rod member 222a and the sliding member 222b are tightly plugged and unplugged, so that the push rod member 222a and the sliding member 222b are detachably connected, realizing the convenience of disassembling and assembling the connection between the push rod member 222a and the sliding member 222b, and the connection between the push rod member 222a and the sliding member 222b has good sealing performance. During use, when it is necessary to replace the atomization core structure 200, the push rod member 222a can be first pulled out, and then the sliding member 222b can be pulled out, which improves the convenience of using the atomizer 10. Of course, when replacing the atomization assembly 224, the push rod member 222a can also be first pulled out, and then the atomization assembly 224 in the sliding member 222b can be taken out, which is convenient and fast, and greatly improves the convenience of maintaining and disassembling and assembling the atomization core structure 200.

[0049] As Figures 2 to 3As shown, further, the overcurrent channel 203b includes an air flow through hole 2032 and a mounting groove 2034 that are connected and communicated. The air flow through hole 2032 is communicated with the air inlet channel 203a. The atomization assembly 224 is disposed in the mounting groove 2034 and is tightly connected to the sliding member 222b. The mounting groove 2034 is communicated with the oil through hole 205. In this embodiment, the outer diameter of the atomization assembly 224 and the inner diameter of the mounting groove 2034 are both larger than the inner diameter of the air flow through hole 2032, so that the atomization assembly 224 is reliably limited in the mounting groove 2034 to prevent the atomization assembly 224 from falling off the sliding member 222b. An atomization integrated channel 224a is formed in the middle of the atomization assembly 224. The atomized vapor formed by heating and atomizing the liquid by the atomization assembly 224 is collected in the atomization integrated channel 224a. In addition, the atomization integrated channel 224a is communicated with the movable rod 120 and the air flow through hole 2032 respectively to form atomized gas in the atomization integrated channel 224a, and the atomized gas flows out through the movable rod 120 and the air outlet hole 103. The oil inlet hole 105 is in alignment and communication with the oil through hole 205. Thus, when in use, that is, when the oil inlet hole 105 is communicated with the oil storage cavity 101, the atomized liquid can quickly flow into the mounting groove 2034 through the oil inlet hole 105 and the oil through hole 205.

[0050] As Figures 2 to 3 shown, in one embodiment, the push rod assembly 222 further includes a first oil locking ring 222c and a second oil locking ring 222d. The first oil locking ring 222c and the second oil locking ring 222d are both sleeved on the outer peripheral wall of the sliding member 222b, and the oil through hole 205 is located between the first oil locking ring 222c and the second oil locking ring 222d, so that the atomized liquid entering through the oil through hole 205 is reliably blocked between the first oil locking ring 222c, the second oil locking ring 222d, the push rod member 222a and the sliding member 222b. Thus, the atomized liquid can only flow into the atomization channel 203 through the oil inlet hole 105 and the oil through hole 205. The first oil locking ring 222c and the second oil locking ring 222d are both used to elastically abut against the inner peripheral wall of the movable rod 120, so that the first oil locking ring 222c is tightly connected between the push rod member 222a and the sliding member 222b, and at the same time the second oil locking ring 222d is tightly connected between the push rod member 222a and the sliding member 222b, improving the reliability of the tight plug-in connection between the push rod member 222a and the sliding member 222b. In this embodiment, the first oil locking ring 222c and the second oil locking ring 222d can both be silicone rubber rings or rubber rings, so that the first oil locking ring 222c and the second oil locking ring 222d both have good elasticity, improving the sealing performance of the sliding connection between the sliding member 222b and the push rod assembly 222.

[0051] As Figures 2 to 3As shown, in one embodiment, an annular resisting step 2222 is formed on the outer peripheral wall of the sliding member 222b adjacent to the end of the push rod member 222a. The annular resisting step 2222 is used to abut against the movable rod member 120. The oil passage hole 205 is formed on the outer peripheral wall of the sliding member 222b, so that the push rod member 222a is sleeved on the sliding member 222b, and the push rod member 222a can better abut against the sliding member 222b. In this embodiment, the oil passage hole 205 is formed on the outer peripheral wall of the sliding member 222b.

[0052] As Figures 2 to 3 shown, as Figures 2 to 3 shown, in one embodiment, the push rod member 222a includes a push rod sleeve 2221, a positive conductive column 2223 and a negative conductive column 2225. The push rod sleeve 2221 is sleeved on the sliding member 222b and is detachably connected to the sliding member 222b. The push rod sleeve 2221 abuts against the sliding member 222b, so that the push rod member 222a abuts against the sliding member 222b and is detachably connected to the sliding member 222b, improving the convenience of use of the atomization core assembly 300. It can be understood that in other embodiments, the push rod member 222a and the sliding member 222b are not limited to being detachably connected. For example, the push rod member 222a and the sliding member 222b can be integrally formed structures.

[0053] As Figures 2 to 3 shown, in one embodiment, the air inlet passage 203a is formed in the push rod sleeve 2221, so that the push rod member 222a is formed with the air inlet passage 203a.

Both the first mounting hole 3122 and the second mounting hole 3124 communicate with the air inlet passage 203a. The positive conductive column 2223 is disposed in the first mounting hole 3122, and the negative conductive column 2225 is disposed in the second mounting hole 3124. The atomization core assembly 320 is connected to the positive conductive column 2223 and the negative conductive column 2225 respectively through the air inlet passage 203a, so that the atomization core assembly 320 is externally conducted through the positive conductive column 2223 and the negative conductive column 2225 respectively, and at the same time, the positive conductive column 2223 and the negative conductive column 2225 are integrally mounted on the push rod member 222a, thereby making the structure of the atomization core assembly 300 more compact.

[0054] As Figures 2 to 3As shown, in one embodiment, the oil cup member 110 is provided with an opening groove 107. The opening groove 107 communicates with the oil storage cavity 101. The fixing base 210 is located in the opening groove 107 and is detachably connected to the oil cup member 110. Further, the fixing base 210 is in interference fit with the oil cup member 110, so that the fixing base 210 is tightly connected to the oil cup member 110, and at the same time, the detachable connection between the fixing base 210 and the oil cup member 110 is realized, improving the convenience of disassembling and assembling the connection between the fixing base 210 and the oil cup member 110. In this embodiment, the fixing base 210 has elasticity. During disassembly, by pressing the side wall of the fixing base 210, the fixing base 210 can be pulled out of the oil cup member 110 to realize the separation of the fixing base 210 and the oil cup member 110. Specifically, the fixing base 210 can be a plastic part or a silicone part, and the hardness of the fixing base 210 is greater than that of the sealing member 130, so that the fixing base 210 can better support and abut against the sealing member 130, and at the same time, the fixing base 210 is in interference fit and elastically connected to the oil cup member 110. To further improve the tightness of the connection between the fixing base 210 and the oil cup member 110, also refer to Figure 4 , further, a plurality of spaced-apart clamping bosses 212 are protruded on the outer peripheral wall of the fixing base 210. Each clamping boss undergoes elastic deformation at the connection between the fixing base 210 and the oil cup member 110, further improving the tightness of the connection between the fixing base 210 and the oil cup member 110. Further, a pressing groove 213 is formed on the outer wall of the fixing base 210. By pressing the fixing base 210 through the pressing groove, the fixing base 210 can be pulled out of the oil cup member 110 to realize the separation of the fixing base 210 and the oil cup member 110, improving the convenience of use of the atomizer 10. In this embodiment, the number of pressing grooves is two, and the two pressing grooves are respectively arranged on the opposite sides of the fixing base 210.

The first conductive portion 2242 is electrically connected to the positive conductive column through the air inlet channel 203a, and the second conductive portion 2244 is electrically connected to the negative conductive column through the air inlet channel 203a, enabling the conductive atomization member 224b to be externally conducted with the positive conductive column 2223 and the negative conductive column 2225 respectively through the air inlet channel 203a. Further, the push rod sleeve 2221 is provided with a first through hole 3125 and a second through hole 3127. The first through hole is arranged to avoid the first installation hole, and the second through hole is arranged to avoid the second installation hole.

[0057] The present application also provides an electronic atomization device, including the atomizer 10 described in any of the above embodiments. As Figures 1 to 3 shown, further, the atomizer 10 includes an oil cup assembly 100 and an atomization core structure 200, and the atomization core structure 200 is detachably connected to the oil cup assembly 100. The oil cup assembly 100 includes an oil cup part 110, a movable rod 120 and a seal 130. The oil cup part 110 forms an oil storage cavity 101 and an air outlet hole 103. The movable rod 120 is movably connected to the oil cup part 110, and the oil storage cavity 101 is separated from the air outlet hole 103 by the movable rod 120, and the movable rod 120 is communicated with the air outlet hole 103. The seal 130 is located in the oil storage cavity 101 and is tightly connected to the oil cup part 110, and the seal 130 is sleeved on the movable rod 120 and is movably connected to the movable rod 120. Since the seal 130 is also movably connected to the oil cup part 110, the positions where the movable rod 120 is connected to the seal 130 and the oil cup part 110 are adjustable.

[0058] Further, the atomization core structure 200 includes a fixed seat 210 and an atomization push rod integrated part 220. The fixed seat 210 is detachably connected to the oil cup assembly 100, so that the atomization core structure 200 is detachably connected to the oil cup assembly 100. The atomization push rod integrated part 220 includes a push rod assembly 222 and an atomization assembly 224. The push rod assembly 222 is connected to the fixed seat 210, so that the atomization push rod integrated part 220 is connected to the fixed seat 210. Further, the push rod assembly 222 is provided with an air inlet hole 201, an atomization channel 203 and an oil passing hole 205, and the atomization channel 203 is communicated with the air outlet hole 103. The fixed seat 210 abuts against the seal 130 to reliably limit the seal 130 in the oil storage cavity 101.

[0059] The movable rod 120 is provided with an oil inlet hole 105. The atomization assembly 224 is disposed in the atomization channel 203, and the atomization assembly 224 is correspondingly arranged with the oil passing hole 205. The push rod assembly 222 is used to push the movable rod 120 of the oil cup assembly 100 to a predetermined position during use, that is, to push the movable rod 120 to move relative to the seal 130 and the oil cup member 110 to a predetermined position during use, so that the oil storage cavity 101 of the oil cup member 110 of the oil cup assembly 100 communicates with the oil passing hole 205. In this embodiment, the push rod assembly 222 is inserted into the movable rod 120, and the atomization channel 203 communicates with the movable rod 120. It can be understood that before use, such as during transportation, the movable rod 120 is respectively connected to the seal 130 and the oil cup member 110. At this time, the movable rod 120 is respectively in the initial position relative to the seal 130 and the oil cup member 110, that is, at this time, the seal 130 is sleeved on the part of the movable rod 120 where the oil inlet hole 105 is opened, so that the oil inlet hole 105 is blocked in the seal 130, that is, the oil inlet hole 105 does not communicate with the oil storage cavity 101. At this time, the atomized liquid cannot flow out of the oil storage cavity 101, and the atomized liquid is reliably stored in the oil storage cavity 101. When in use, the fixed seat 210 is respectively connected to the oil cup assembly 100 and the fixed seat 210, and the movable rod 120 is pushed to move relative to the seal 130 and the oil cup member 110 respectively through the push rod assembly 222, so that the movable rod 120 moves relative to the seal 130 and the oil cup member 110 respectively until the movable rod 120 is respectively in a predetermined position relative to the seal 130 and the oil cup member 110. At this time, the oil inlet hole 105 communicates with the oil storage cavity 101, that is, the oil storage cavity 101 communicates with the atomization channel 203 through the oil passing hole 205, and the air inlet hole 201 and the oil passing hole 205 both communicate with the atomization channel 203, so that the atomized liquid in the oil storage cavity 101 flows into the atomization channel 203 through the oil passing hole 205 and is heated and atomized by the atomization assembly 224.

[0060] The above-mentioned electronic atomization device, the push rod assembly 222 is used to push the movable rod 120 of the oil cup assembly 100 to a predetermined position when the fixed seat 210 is connected to the oil cup assembly 100, so that the oil storage cavity 101 of the oil cup member 110 of the oil cup assembly 100 communicates with the oil passing hole 205, and the atomization liquid in the oil storage cavity 101 flows into the atomization channel 203 through the oil passing hole 205. Since the atomization assembly 224 is arranged in the atomization channel 203 and the atomization assembly 224 is arranged corresponding to the oil passing hole 205, the atomization assembly 224 heats and atomizes the atomization liquid; before use, such as during transportation, since the oil passing hole 205 is not communicated with the oil storage cavity 101, it avoids the problem that the atomization liquid in the oil storage cavity 101 of the oil cup assembly 100 contacts the atomization assembly 224 in advance and is oxidized, and at the same time can realize reliable sealing of the oil cup assembly 100; since the fixed seat 210 is detachably connected to the oil cup assembly 100, the push rod assembly 222 is connected to the fixed seat 210, and since the push rod assembly 222 is provided with the atomization channel 203 and the atomization assembly 224 is arranged in the atomization channel 203, that is, the atomization assembly 224 is assembled in the atomization channel 203, so that the atomization push rod integrated part 220 is connected to the fixed seat 210. When the atomization liquid in the oil cup assembly 100 is used up, the fixed seat 210 is removed from the oil cup assembly 100 and assembled with a new oil cup assembly 100 for use, realizing the reuse of the atomization core structure 200, and the oil cup assembly 100 is a simple accessory without the atomization core structure 200. When the atomization liquid in the oil cup assembly 100 is used up, it is directly discarded with less environmental pollution, solving the problem of poor environmental protection of the atomizer 10.

[0061] Furthermore, the electronic atomization device further includes a battery rod. The atomizer 10 is detachably connected to the battery rod, and the conductive parts of the battery rod are electrically connected to the positive and negative conductive ends of the atomization assembly 224 respectively. In this embodiment, the conductive parts of the battery rod are electrically connected to the positive conductive column and the negative conductive column respectively, so as to energize the atomization assembly 224 and heat and atomize the atomization liquid. In one embodiment, the battery rod is detachably connected to the fixed seat 210, so that the battery rod is detachably connected to the atomizer 10. In this embodiment, the battery rod is magnetically connected to the fixed seat 210, and the battery rod is sleeved on the oil cup member 110, realizing the quick disassembly and assembly of the battery rod and the fixed seat 210, and at the same time realizing the reliable connection between the battery rod and the fixed seat 210.

[0062] Further, the battery rod includes a battery rod sleeve and a magnetic metal piece. The battery rod sleeve is sleeved on the oil cup member 110, and the battery rod sleeve is provided with a first magnetic metal piece and a second magnetic metal piece. The fixed seat 210 is provided with a first magnetic member 218 and a second magnetic member 219. The first magnetic metal piece is magnetically connected to the first magnetic member correspondingly, and the second magnetic metal piece is magnetically connected to the second magnetic member correspondingly, so that the battery rod is magnetically connected to the fixed seat 210. In this embodiment, both the first magnetic member and the second magnetic member are magnet pieces, so that both the first magnetic member and the second magnetic member have good magnetic properties.

[0063] As Figure 6 shown, further, the fixed seat 210 is formed with a formed hole 215 and a ventilation hole 217 that are communicated with each other. The ventilation hole is formed on the side wall of the fixed seat 210, and the formed hole is disposed adjacent to the fixed through hole. The battery rod further includes a microphone member. The microphone member is disposed on the battery rod sleeve. The formed hole is correspondingly disposed with the microphone member. When the user inhales, a negative pressure is generated in the movable rod member 120. The air flow in the ventilation hole and the air flow in the air inlet hole 201 both flow into the movable rod member 120, so that a negative pressure is generated on the surface of the ventilation hole and the microphone member, improving the sensitivity of the microphone induction inside the battery rod, and further realizing the rapid startup of the electronic atomization device. A formed hole communicated with the ventilation hole is formed on the fixed seat, enabling the fixed seat to be better demolded and forming the ventilation hole better at the same time.

[0064] Compared with the prior art, the present invention has at least the following advantages:

[0065] 1. For the atomization core structure 200 of the present application, the push rod assembly 222 is used to push the movable rod member 120 of the oil cup assembly 100 to move to a predetermined position when the fixed seat 210 is connected to the oil cup assembly 100, so that the oil storage cavity 101 of the oil cup member 110 of the oil cup assembly 100 is communicated with the oil passing hole 205, and the atomization liquid in the oil storage cavity 101 flows into the atomization channel 203 through the oil passing hole 205. Since the atomization assembly 224 is disposed in the atomization channel 203 and the atomization assembly 224 is correspondingly disposed with the oil passing hole 205, the atomization assembly 224 heats and atomizes the atomization liquid; before use, such as during transportation, since the oil passing hole 205 is not communicated with the oil storage cavity 101, it avoids the problem of premature contact between the atomization liquid in the oil storage cavity 101 of the oil cup assembly 100 and the atomization assembly 224 and oxidation, and at the same time can realize reliable sealing of the oil cup assembly 100;

[0066] 2. Since the fixing base 210 is detachably connected to the oil cup assembly 100, the push rod assembly 222 is connected to the fixing base 210. Also, since the push rod assembly 222 is provided with an atomization channel 203 and the atomization assembly 224 is disposed within the atomization channel 203, that is, the atomization assembly 224 is assembled within the atomization channel 203. Thus, the atomization push rod integrated part 220 is connected to the fixing base 210. When the atomization liquid within the oil cup assembly 100 is used up, the fixing base 210 is removed from the oil cup assembly 100 and assembled with a new oil cup assembly 100 for use, realizing the reuse of the atomization core structure 200. The oil cup assembly 100 is a simple accessory without the atomization core structure 200. When the atomization liquid within the oil cup assembly 100 is used up, it can be directly discarded with less environmental pollution, solving the problem of poor environmental friendliness existing in the atomizer 10.
