Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of electronic atomization, and in particular relates to an oil guide body, an atomization component and an atomizer. Background Art
[0002] At present, during the process of smoking electronic cigarettes, as the number of puffs increases, the flavor and taste of the smoked electronic cigarettes will become weaker and weaker, commonly known as taste attenuation, which is a common phenomenon in the electronic cigarette industry. This is mainly because the boiling points of the main ingredients in the electronic cigarette oil, such as glycerin, propylene glycol, various components of flavors, sweeteners, cooling agents, etc., are different, usually ranging from 60-280℃, and the atomization temperature of electronic cigarettes is usually around 280℃, so at a constant atomization temperature, the volatilization speed of each substance is naturally fast or slow, resulting in the difference between the proportion of each component in the remaining oil and the original proportion as the number of puffs increases, resulting in the taste attenuation of electronic cigarettes.
[0003] For the above shortcomings, the common practice in the industry is to appropriately add excessive amounts of volatile substances to offset the taste decay caused by the rapid decrease in the content of volatile substances. However, these will intensify the aroma of certain substances in the early stage of smoking, and only reduce or alleviate the taste decay in the later stage. The whole practice does not substantially maintain the consistency of the taste of e-cigarettes.
[0004] Therefore, the industry urgently needs a technology that can completely solve the problem of e-cigarette flavor attenuation and promote the progress of the e-cigarette industry. Summary of the invention
[0005] The technical problem to be solved by the present invention is to provide an oil guide body, an atomization assembly and an atomizer, aiming to solve the technical problem of flavor attenuation of electronic cigarettes in the related art.
[0006] To solve the above technical problems, the present invention is implemented as follows: an oil guide body is used for an atomizer, and the oil guide body includes: a first oil guide body, a second oil guide body, and a heat insulation structure arranged between the first oil guide body and the second oil guide body, one of the first oil guide body and the second oil guide body is used to directly contact the atomized liquid of the atomizer, and the other is used to contact the heating element of the atomizer, the heat insulation structure is used to separate the first oil guide body and the second oil guide body, the heat insulation structure is provided with a through hole and a valve component, the through hole connects the first oil guide body and the second oil guide body, and the valve component is used to control the opening and closing of the through hole according to the change of the atomization temperature of the heating element.
[0007] Furthermore, the oil-conducting body is a flexible oil-conducting body.
[0008] Further, when the atomization temperature of the heating element is within a first temperature range, the valve component is in a first state; and when the atomization temperature of the heating element is within a second temperature range, the valve component is in a second state.
[0009] Furthermore, the valve component is arranged in the through hole; when the valve component is in a first state, there is a gap between the outer peripheral side of the valve component and the hole wall of the through hole; when the valve component is in a second state, the outer peripheral side of the valve component abuts against the hole wall of the through hole.
[0010] Furthermore, a transverse cross-sectional shape of the valve element matches a transverse cross-sectional shape of the through hole.
[0011] Furthermore, the valve element is made of memory material.
[0012] Furthermore, the first oil-conducting body and the second oil-conducting body are both oil-conducting layers, the thermal insulation structure is a thermal insulation layer, the transverse cross-sectional shape of the oil-conducting body layer matches the transverse cross-sectional shape of the thermal insulation layer, and the cross-sectional area of the oil-conducting body layer is equal to the cross-sectional area of the thermal insulation layer.
[0013] Furthermore, the thickness of the thermal insulation layer is between 0.01-2 mm.
[0014] Furthermore, the oil-conducting layer includes at least one layer of linen cloth and / or at least one layer of non-woven fabric.
[0015] Furthermore, an atomizer assembly has an assembly space, the atomizer assembly includes a heating element and the oil guide body as described above, the heating element and the oil guide body are both assembled in the assembly space, and the heating element is assembled on the side of the first oil guide body.
[0016] Furthermore, an atomizer is provided, comprising a liquid storage chamber having an oil inlet hole, an atomization channel, and the atomization assembly as described above, wherein the atomization assembly is at least partially disposed in the atomization channel and communicated with the liquid storage chamber through the oil inlet hole.
[0017] Compared with the related art, the oil guide body, atomization assembly and atomizer in the present invention have the following beneficial effects:
[0018] Take the case where the heating element is located on one side of the first oil-conducting body as an example. When the atomizer is not working and is at a normal temperature, the valve component makes the through hole in a connected state. The atomized liquid will first flow from the liquid storage chamber to the second oil-conducting body in the oil inlet area. Since the through hole is in a connected state, the atomized liquid of the second oil-conducting body will flow to the first oil-conducting body through the through hole. At this time, the first oil-conducting body can be filled with atomized liquid, and the atomized liquid can be stored in the first oil-conducting body to prepare for the subsequent work of the atomizer. When the atomizer is working and the atomizer is in a high temperature state, the valve component makes the through hole in a closed state. Due to the blocking effect of the valve component, the atomized liquid cannot flow from the second oil-conducting body to the first oil-conducting body; and because the heat insulation structure has a heat insulation effect, the heat insulation structure can cut off the heat transfer between the oil inlet area and the atomization area, that is, the atomizer can only heat and atomize the atomized liquid in the first oil-conducting body, while the atomized liquid in the second oil-conducting body in the oil inlet area will not be heated and atomized. When the suction stops and the atomization temperature drops, the valve element makes the through hole connected again, and the atomized liquid of the second oil-conducting body can continue to flow to the first oil-conducting body through the through hole. The atomized liquid is stored in the first oil-conducting body, waiting for the next suction. Therefore, the present invention can achieve intermittent oil supply and intermittent atomization during continuous suction and suspension of suction, and can ensure the continuous stability of the atomized liquid composition in the liquid storage chamber. The present invention can achieve intermittent oil supply by means of heat interception, which effectively avoids the continuous and rapid volatilization of low-boiling point substances under the condition of suction and heat, and avoids the continuous reduction of low-boiling point substances in the remaining smoke oil, which completely solves the problem of flavor attenuation.

[0027] Embodiment:
[0028] Please refer to Figure 1-3 , an atomizer, comprising a liquid storage cavity 8 having an oil inlet hole 7, an atomization channel 9, and an atomization component, wherein the atomization component is at least partially disposed in the atomization channel 9 and communicates with the liquid storage cavity 8 through the oil inlet hole 7. The atomization component has an assembly space, and the atomization component includes a heating element 6 and an oil guiding body. Both the heating element 6 and the oil guiding body are assembled in the assembly space. The oil guiding body includes a first oil guiding body 1, a second oil guiding body 3, and a heat insulation structure 2 disposed between the first oil guiding body 1 and the second oil guiding body 3. One of the first oil guiding body 1 and the second oil guiding body 3 is used to directly contact the atomization liquid of the atomizer, and the other is used to contact the heating element 6 of the atomizer. The heat insulation structure 2 is used to separate the first oil guiding body 1 and the second oil guiding body 4. The heat insulation structure 3 is provided with a through hole 4 and a valve member 5. The through hole 4 communicates the first oil guiding body 1 and the second oil guiding body 3, and the valve member 5 is used to control the on-off of the through hole 4 according to the change of the atomization temperature of the heating element 6.
[0029] Specifically, the heat insulation structure 2 is used to separate the assembly space into an oil inlet area and an atomization area. In some embodiments, the heating element 6 is assembled on one side of the first oil guide body; the heating element 6 and the first oil guide body 1 are located in the atomization area, the second oil guide body 3 is located in the oil inlet area, and the oil inlet area is connected to the liquid storage chamber 8 through the oil inlet hole 7. In other embodiments, the heating element 6 is assembled on one side of the second oil guide body 3 and is located in the atomization area; the first oil guide body 1 is located in the oil inlet area.
[0030] The thermal insulation structure 2 is provided with a through hole 4 and a valve member 5; the through hole 4 connects the oil inlet area and the atomization area, that is, the through hole 4 connects the first oil guide body 1 and the second oil guide body 3. When the oil guide body is applied to the atomizer, the valve member 5 is used to control the opening and closing of the through hole 4 according to the atomization temperature.
[0031] Take the heating element 6 located on the side of the first oil guide body as an example. When the atomizer is not working and the atomizer is at normal temperature, the valve 5 makes the through hole 4 in a connected state. The atomized liquid will first flow from the liquid storage chamber 8 to the second oil guide body 3 in the oil inlet area. Since the through hole 4 is in a connected state, the atomized liquid of the second oil guide body 3 will flow to the first oil guide body 1 through the through hole 4. At this time, the first oil guide body 1 can be filled with atomized liquid, and the atomized liquid can be stored in the first oil guide body 1 to prepare for the subsequent work of the atomizer. When the atomizer is working and the atomizer is in a high temperature state, the valve 5 makes the through hole 4 in a closed state. Due to the blocking effect of the valve 5, the atomized liquid cannot flow from the second oil guide body 3 to the first oil guide body 1; and because the heat insulation structure 2 has a heat insulation effect, the heat insulation structure 2 can cut off the heat transfer between the oil inlet area and the atomization area, that is, the atomizer can only heat and atomize the atomized liquid in the first oil guide body 1, while the atomized liquid in the second oil guide body 3 in the oil inlet area will not be heated and atomized. When the suction stops and the atomization temperature drops, the valve 5 makes the through hole 4 connected again, and the atomized liquid of the second oil-conducting body 3 can continue to flow to the first oil-conducting body 1 through the through hole 4, and the atomized liquid is stored in the first oil-conducting body 1, waiting for the next suction. Therefore, the present invention can achieve intermittent oil supply and intermittent atomization during continuous suction and stopping, and can ensure the continuous stability of the atomized liquid components in the liquid storage chamber 8. The present invention can achieve intermittent oil supply by means of heat interception, effectively avoiding the continuous and rapid volatilization of low-boiling point substances under the condition of suction and heating, avoiding the continuous reduction of low-boiling point substances in the remaining smoke oil, and completely solving the problem of flavor attenuation.
[0032] Further, in some embodiments, the oil-conducting body may be a flexible oil-conducting body. Specifically, the flexible oil-conducting body may be oil-conducting cotton. In some embodiments, the oil-conducting body may be a hard oil-conducting body.
[0033] Further, when the atomization temperature of the heating element 6 is in the first temperature range, the valve member 5 is in the first state; when the atomization temperature of the heating element 6 is in the second temperature range, the valve member 5 is in the second state.
[0034] Specifically, the oil guide body is applied to the atomizer. According to the actual situation of the atomizer, the first temperature range is less than 60°C, and the second temperature range is 60-80°C and greater than 80°C. When the temperature is less than 60°C, the valve member 5 is in the first state, the valve member 5 makes the through hole 4 in a connected state, and the atomized liquid can flow between the first oil guide body 1 and the second oil guide body 3 through the through hole 4; when the temperature is 60-80°C and greater than 80°C, the valve member 5 is in the second state, the valve member 5 makes the through hole 4 in a closed state.
[0035] Take the heating element 6 located on one side of the first oil-conducting body as an example. When the atomizer is not working, the temperature of the atomizer is less than 60°C, the valve member 5 is in the first state, and the valve member 5 makes the through hole 4 in a connected state. The atomized liquid will first flow from the liquid storage chamber 8 to the second oil-conducting body 3 in the oil inlet area. Since the through hole 4 is in a connected state, the atomized liquid of the second oil-conducting body 3 will flow to the first oil-conducting body 1 through the through hole 4. At this time, the first oil-conducting body 1 can be filled with atomized liquid, and the atomized liquid can be stored in the first oil-conducting body 1 to prepare for the subsequent work of the atomizer. When the atomizer is working, the atomizer gradually heats up. When the atomization temperature of the heating element 6 of the atomized liquid is between 60 and 80°C, the valve member 5 is in the second state, and the valve member 5 makes the through hole 4 in a closed state. As the atomization temperature gradually increases, the valve member 5 is always in the second state, and the valve member 5 makes the through hole 4 always in a closed state. Due to the blocking effect of the valve member 5, the atomized liquid cannot flow from the second oil-conducting body 3 to the first oil-conducting body 1; and because the heat-insulating structure 2 has a heat-insulating effect, the heat-insulating structure 2 can cut off the heat transfer between the oil inlet area and the atomizing area, that is, the atomizer can only heat and atomize the atomized liquid in the first oil-conducting body 1, while the atomized liquid in the second oil-conducting body 3 in the oil inlet area will not be heated and atomized. When the suction is stopped, the atomization temperature drops. When it drops to less than 60°C, the valve member 5 returns to the first state, and the valve member 5 makes the through hole 4 return to the connected state, and the atomized liquid of the second oil-conducting body 3 can continue to flow to the first oil-conducting body 1 through the through hole 4, and the atomized liquid is stored in the first oil-conducting body 1, waiting for the next suction. Therefore, the present invention can realize intermittent oil supply and intermittent atomization in the process of continuous suction and stopping suction, and can ensure the continuous stability of the atomized liquid components in the liquid storage chamber 8. The present invention can achieve intermittent oil supply by means of heat interception, effectively avoiding the low-boiling point substances from volatilizing too quickly when being heated during suction, avoiding the continuous reduction of the low-boiling point substances in the remaining e-liquid, and completely solving the problem of flavor attenuation.
[0036] For further information, see Figure 2 , the valve member 5 is arranged in the through hole 4; when the valve member 5 is in the first state, there is a gap between the outer peripheral side of the valve member 5 and the hole wall of the through hole 4; when the valve member 5 is in the second state, the outer peripheral side of the valve member 5 abuts against the hole wall of the through hole 4.
[0037] Specifically, the oil guide body is applied to the atomizer. When the valve member 5 is in the first state, the atomization temperature of the atomizer is correspondingly less than 60°C, and there is a gap between the outer peripheral side of the valve member 5 and the hole wall of the through hole 4; when the valve member 5 is in the second state, the atomization temperature of the atomizer is correspondingly greater than 60°C, and the outer peripheral side of the valve member 5 abuts against the hole wall of the through hole 4.
[0038] Take the case where the heating element 6 is located on the side of the first oil guide element 1 as an example. Figure 2 When the atomizer is not working, the temperature of the atomizer is less than 60°C, and the valve member 5 is in the first state. At this time, there is a gap between the outer peripheral side of the valve member 5 and the hole wall of the through hole 4. The atomized liquid will first flow from the liquid storage chamber 8 to the second oil guide body 3 in the oil inlet area, and the atomized liquid of the second oil guide body 3 will flow to the first oil guide body 1 through the gap between the outer peripheral side of the valve member 5 and the hole wall of the through hole 4. At this time, the first oil guide body 1 can be filled with atomized liquid, and the atomized liquid can be stored in the first oil guide body 1 to prepare for the subsequent work of the atomizer. When the atomizer is working, the atomizer gradually heats up. When the atomization temperature of the heating element 6 of the atomized liquid rises to 60°C-80°C, the valve member 5 is in the second state, and the valve member 5 can completely block the through hole 4, that is, the outer peripheral side of the valve member 5 can abut against the hole wall of the through hole 4, and as the atomization temperature gradually increases, the valve member 5 is always in the second state. Since the through hole 4 is blocked by the valve member 5, the atomized liquid cannot flow from the second oil-conducting body 3 to the first oil-conducting body 1. Since the heat-insulating structure 2 has a heat-insulating effect, the heat-insulating structure 2 can cut off the heat transfer between the oil inlet area and the atomizing area, that is, the atomizer can only heat and atomize the atomized liquid in the first oil-conducting body 1, while the atomized liquid in the second oil-conducting body 3 in the oil inlet area will not be heated and atomized. When the suction is stopped, the atomization temperature drops. When it drops to less than 60°C, the valve member 5 gradually opens the through hole 4, and the gap between the outer peripheral side of the valve member 5 and the hole wall of the through hole 4 is restored. The atomized liquid of the second oil-conducting body 3 can continue to flow to the first oil-conducting body 1 through the gap, and the atomized liquid is stored in the first oil-conducting body 1, waiting for the next suction. Therefore, the present invention can realize intermittent oil supply and intermittent atomization in the process of continuous suction and stopping suction, and can ensure the continuous stability of the atomized liquid components in the liquid storage chamber 8. The present invention can achieve intermittent oil supply by means of heat interception, effectively avoiding the low-boiling point substances from volatilizing too quickly when being heated during suction, avoiding the continuous reduction of the low-boiling point substances in the remaining e-liquid, and completely solving the problem of flavor attenuation.
[0039] For further information, see Figure 2, the transverse cross-sectional shape of the valve member 5 matches the transverse cross-sectional shape of the through hole 4. Specifically, the cross-sectional shape of the through hole 4 can be circular, rectangular, triangular, trapezoidal, elliptical, etc., and the transverse cross-sectional shape of the valve member 5 matches the through hole 4. Therefore, when the valve member 5 is located in the through hole 4 and the valve member 5 is in the second state, the valve member 5 can completely block the through hole 4, that is, the outer peripheral side of the valve member 5 can completely abut against the hole wall of the through hole 4.
[0040] Furthermore, the valve element 5 is made of memory material.
[0041] Specifically, the shape of the memory material matches the shape of the through hole 4, and the cross-sectional shape of the hole can be circular, rectangular, triangular, trapezoidal, elliptical, etc. The memory material can be a metal material or other materials, such as memory alloy, memory ceramic or memory polymer. The characteristics of this material must be able to expand or restore shape with changes in temperature. Figure 2 , at room temperature, the valve member 5 is in the first state, at which time the memory material maintains its original state, and the size of the memory material is slightly smaller than the size of the through hole 4, that is, the gap between the outer peripheral side of the memory material and the hole wall of the through hole 4, which is equivalent to the through hole 4 being in a connected state. When the oil guide body is applied to the atomizer, the atomized liquid in the second oil guide body 3 can flow to the first oil guide body 1 through the gap. When the atomizer is working, as the atomization temperature rises, the volume of the memory material gradually expands. When the temperature rises to 60-80°C, the valve member 5 is in the second state, at which time the memory material will expand and deform until it completely fills the gap between the outer peripheral side of the memory material and the hole wall of the through hole 4, thereby blocking the through hole 4 of the thermal insulation structure 2. The atomized liquid in the second oil guide body 3 cannot flow to the first oil guide body 1, and the atomizer can only heat and atomize the atomized liquid originally stored in the first oil guide body 1. When the inhalation stops, the heat of the heating element 6 will decrease, and the atomization temperature will also decrease. Then, the temperature of the memory material in the through hole 4 will also decrease. The memory material will automatically shrink due to the thermal expansion and contraction effect, and the memory material will return to its original state. The gap between the memory material and the through hole 4 will open, and the atomized liquid in the second oil-conducting body 3 can continue to be transferred to the first oil-conducting body 1 through the gap. The atomized liquid is stored in the first oil-conducting body 1, waiting for the next inhalation. The present invention can control the amount of atomized liquid when the atomization temperature is high (the atomization temperature reaches the boiling point of the low-boiling-point substance in the atomized liquid) through the heat insulation structure 2 and the memory material, and realize intermittent oil supply, which effectively avoids the low-boiling-point substance from volatilizing too quickly when the suction is heated, and avoids the continuous reduction of the low-boiling-point substance in the remaining smoke oil, ensuring the continuous stability of the atomized liquid components in the liquid storage chamber 8, and completely solving the problem of flavor attenuation.
[0042] Furthermore, the first oil conducting body 1 and the second oil conducting body 3 are both oil conducting body layers, the thermal insulation structure 2 is a thermal insulation layer, the transverse cross-sectional shape of the oil conducting body layer matches the transverse cross-sectional shape of the thermal insulation layer, and the cross-sectional area of the oil conducting body layer is equal to the cross-sectional area of the thermal insulation layer.
[0043] Specifically, in some embodiments, the first oil-conducting body 1, the second oil-conducting body 3 and the heat-insulating structure 2 are all layered structures, and the transverse cross-sectional shape can be circular, rectangular, triangular, trapezoidal, elliptical, etc. The three shapes are consistent, so that the three can be completely overlapped without any extra space, and the atomized liquid in the liquid storage chamber 8 will pass through the first oil-conducting body 1, and the atomized liquid in the first oil-conducting body 1 will flow to the second oil-conducting body 3 through the through hole 4, so that the purpose of intermittent oil supply can be fully achieved. If the heat-insulating layer is smaller than the area of the oil-conducting body layer, the heat-insulating effect of the heat-insulating layer cannot be fully exerted, and part of the atomized liquid in the second oil-conducting body 3 may also be heated and atomized, and part of the atomized liquid in the second oil-conducting body 3 may continue to flow to the first oil-conducting body 1, and the effect is not ideal. Therefore, the cross-sectional area of the heat-insulating layer should be greater than or equal to the cross-sectional area of the oil-conducting body layer. Preferably, the cross-sectional area of the heat-insulating layer is equal to the cross-sectional area of the oil-conducting body layer. Because if the heat-insulating layer is larger than the area of the oil-conducting layer, part of the through hole 4 may not be covered by the oil-conducting layer, and the heat-insulating effect is not ideal; or although the oil-conducting layer covers the through hole 4, if the oil-conducting layer does not completely cover the heat-insulating layer, it will also cause material waste.
[0044] Furthermore, the thickness of the thermal insulation layer is between 0.01-2 mm.
[0045] Specifically, the material of the thermal insulation structure 2 is a tight, airtight material with a small thermal conductivity, which can be a polymer material with a small thermal conductivity, an inorganic non-metal material with a small thermal conductivity, or an inorganic material with a small thermal conductivity, etc. For example, it can be polytetrafluoroethylene with good air tightness. In this embodiment, the thermal insulation structure 2 is a thermal insulation layer, and the thickness of the thermal insulation layer is between 0.01-2mm, specifically 0.01, 0.05, 0.1, 0.2, 0.5, 0.8, 1, 1.2, 1.5, 1.8, 2mm, etc.
[0046] Further, the oil-conducting body layer includes at least one layer of linen and / or at least one layer of non-woven fabric. Specifically, the first oil-conducting body 1 is the first oil-conducting body layer, and the second oil-conducting body 3 is the second oil-conducting body layer. The first oil-conducting body layer and the second oil-conducting body layer are both composed of several layers of cotton, generally composed of 1-7 layers of cotton, or more layers of cotton. The specific material can be linen or non-woven fabric. When the oil-conducting body layer is two or more layers, the material of each layer of cotton can be the same or different. In addition, in the first oil-conducting body layer and the second oil-conducting body layer, the number of layers of cotton can be the same or different, and the material of the cotton in the same layer can be the same or different. For example, the first oil-conducting body layer can be composed of 5 layers of cotton, and the 5 layers of cotton can be one layer of linen, one layer of non-woven fabric, one layer of non-woven fabric, one layer of linen, one layer of non-woven fabric, and one layer of linen in sequence; or, the 5 layers of cotton can be one layer of linen, one layer of linen, one layer of non-woven fabric, one layer of linen, and one layer of non-woven fabric in sequence; and so on. The second oil-conducting layer can be composed of 7 layers of cotton, and the 7 layers of cotton can be, in sequence, a layer of non-woven fabric, a layer of linen, a layer of non-woven fabric, a layer of non-woven fabric, a layer of linen, a layer of non-woven fabric, and a layer of non-woven fabric; or, the 7 layers of cotton can be, in sequence, a layer of linen, a layer of non-woven fabric, a layer of linen, a layer of non-woven fabric, a layer of linen, a layer of non-woven fabric, and a layer of non-woven fabric; and so on.
[0047] Further, in some embodiments, the assembly space includes an oil inlet area and an atomization area, and the oil inlet area and the atomization area are distributed along the lateral direction of the atomization assembly, see Figure 3 Taking the heating element 6 arranged on the first oil-conducting body 1 as an example, the second oil-conducting body 3, the heat-insulating structure 2, the first oil-conducting body 1 and the heating element 6 of the oil-conducting body are arranged in sequence along the lateral direction of the atomizer, wherein the second oil-conducting body 3 faces the oil inlet hole 7, the oil inlet hole 7 is connected to the liquid storage chamber 8, and the atomized liquid in the liquid storage chamber 8 will flow to the second oil-conducting body 3 through the oil inlet hole 7; the heat-insulating structure 2 is arranged between the first oil-conducting body 1 and the second oil-conducting body 3, and the atomized liquid flows to the first oil-conducting body 1 through the through hole 4 of the heat-insulating structure 2, and the heating element 6 is arranged on the side of the second oil-conducting body 3 away from the heat-insulating structure 2, and the heating element 6 heats the atomized liquid of the atomized second oil-conducting body 3, so that an aerosol can be directly formed on one side of the second oil-conducting body 3, and the aerosol flows in the atomizing channel 9, and the atomizing channel 9 is parallel to the axial direction of the atomizer. Such an arrangement can shorten the flow path of the aerosol, which is conducive to the flow of the aerosol.
[0048] Further, in some embodiments, the assembly space includes an oil inlet area and an atomization area, and the oil inlet area and the atomization area are distributed along the axial direction of the atomization assembly. Taking the heating element arranged in the first oil guide body 1 as an example, the second oil guide body 3, the heat insulation structure 2, the first oil guide body 1 and the heating element 6 in the oil guide body are arranged in sequence along the axial direction of the atomization assembly. When the atomization assembly assembled on the oil guide body is applied to the atomizer, the second oil guide body 3 can be placed close to the liquid storage chamber 8, that is, the second oil guide body 3 is located above the first oil guide body 1 and the heating element 6. In this way, when the through hole 4 is opened, the atomized liquid in the second oil guide body 3 can flow to the first oil guide body 1 more smoothly through the through hole 4 with the help of gravity, thereby accelerating the flow rate of the atomized liquid in the process.
