Description

Technical Field

[0001] The present invention belongs to the technical field of electronic cigarettes, and in particular relates to an electronic cigarette atomization device and the electronic cigarette. Background Art

[0002] Electronic cigarettes, also known as e-cigarettes, are primarily used for smoking cessation and as an alternative to traditional cigarettes. They have a similar appearance and flavor profile to traditional cigarettes, even offering a wider variety of flavors than traditional cigarettes. They also offer the same smoke, flavor, and feel as traditional cigarettes. Because they lack the harmful ingredients found in traditional cigarettes, such as tar and particulate matter, e-cigarettes are gradually replacing traditional cigarettes in the market. Their compact size and portability have made them popular with consumers. The atomizer chamber, where the heating coil resides, is located directly opposite the inhalation port. This is typically connected to the inhalation port via a metal air duct. This can easily lead to condensation within the metal air duct over extended use. This condensation can then flow back into the heating core, mixing with the oil and heating it. This can cause oil to splatter out of the inhalation port, potentially causing burns. Consequently, e-cigarettes with a horizontally positioned heating core have emerged on the market. These utilize an oil hole at the bottom of the oil reservoir to allow oil to seep into the heating core's oil inlet for atomization. In the prior art, since the oil output of the oil hole opened in the oil storage chamber is limited, the oil is slowly replenished to the heating core component. The cotton material located at the bottom of the heating core component can only be replenished by penetrating the cotton material on the top of the heating core component, resulting in uneven oil absorption by the cotton material wrapping the heating core component. When the user continuously draws, the core is prone to become sticky. Summary of the Invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

Therefore, the features defined as "first" or "second" may explicitly or implicitly include such features.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0031] In the present invention, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0032] Reference Figures 1 to 4 As shown, this embodiment provides an electronic cigarette 1000, which includes a power supply device 200 and an atomizer 100. The power supply device 200 is used to power the atomizer 100. The atomizer 100 includes a main body 10 and a heating core component 30. The main body 10 is provided with an oil storage chamber 11, an air inlet and a suction port 14 that are connected to the external air path, and an air flow channel 12 is formed between the air inlet and the suction port 14. The oil storage chamber 11 stores smoke liquid. The heating core component 30, driven by the electrical energy of the power supply component, heats the oil absorbed from the oil storage chamber 11 to generate smoke, which is then discharged from the air flow channel 12 for inhalation by the user.

[0033] like Figure 1 or Figure 2 As shown, in an embodiment of the present invention, the air flow passage 12 includes a suction section 121, an atomization section 122 and a bending section 123 connecting the suction section 121 and the atomization section 122. The suction section 121 is connected to the suction port 14, and the main body 10 is provided with an oil hole 111 on the inner wall between the atomization section 122 and the oil storage chamber 11, so that the oil can flow from the oil storage chamber 11 into the atomization section 122. The heating core component 30 is provided with a first oil inlet 321 and a second oil inlet 322, and when the heating core component 30 is installed on the main body 10, the parts provided with the first oil inlet 321 and the second oil inlet 322 are accommodated in the atomization section 122, so that the internal oil path of the heating core component 30 is connected with the oil path of the oil storage chamber 11 through the atomization section 122.

[0034] Specifically, if Figure 1 or Figure 2 As shown, in this embodiment of the present invention, the atomizing section 122 is arranged horizontally, and the suction section 121 is arranged perpendicular to or at an angle to the atomizing section 122 along the direction of gravity to facilitate user inhalation. The intersection of the atomizing section 122 and the suction section 121 forms the bent section 123. The heating core 30 is inserted horizontally into the atomizing section 122. The heating core 30 defines an atomizing air path 3321 along its axis to communicate with the bent section 123. By bending the suction section 121 and the atomizing section 122 of the air passage 12, when the heating core 30 is electrically driven to heat the oil, causing oil frying, the smoke liquid splashes directly toward the bent section 123 and then is discharged along the suction section 121 from the suction port 14 for the user to inhale. This effectively prevents the heating core 30 from directly facing the suction section 121, causing scalding smoke liquid to splash into the user's mouth and cause discomfort.

[0035] In order to facilitate uniform oil adsorption of the heating core component 30, the first oil inlet 321 is arranged above the second oil inlet 322 in the direction of gravity, so that oil can be introduced into the interior of the heating core component 30 from the top and bottom of the heating core component 30 at the same time, to prevent the oil from being difficult to penetrate into the higher part of the heating core component 30, resulting in uneven oil adsorption and the phenomenon of burning the cotton material inside the heating core component 30 when the atomizer is working.

[0036] At the same time, if Figures 2 to 4As shown, in an embodiment of the present invention, in order to further ensure uniform adsorption of the oil inside the heating core component 30, in this embodiment, the main body 10 is further provided with a light-transmitting area 13 at a position corresponding to the oil storage cavity 11. The light-transmitting area 13 can be formed by making the main body 10 adopt a light-transmitting member such as transparent or translucent plastic or glass, or by IML in-mold injection molding, so that the main body 10 corresponds to the position of the oil storage cavity 11 to form a light-transmitting area 13 for light to enter, or by using a transparent member plus a protective cover, and the protective cover part is provided with a window 220 to form the light-transmitting area 13, etc., which are convenient for users to observe the smoke liquid in the oil storage cavity 11, all of which fall within the protection scope of the present invention.

[0037] At the same time, if Figure 1 or Figure 2 As shown, in this embodiment of the present invention, to prevent oil from accumulating in the oil reservoir 11, the atomizing section 122 is positioned below the oil reservoir 11 in the direction of gravity. Furthermore, the oil passage hole 111 is provided on the bottom wall of the oil reservoir 11. This allows the oil to flow into the atomizing section 122 through the oil passage hole 111 provided on the bottom wall of the oil reservoir 11 under the action of gravity.

[0038] Furthermore, if Figure 1 or Figure 2 As shown, in an embodiment of the present invention, the first oil inlet 321 is located at the top of the heating core component 30 along the direction of gravity, and is arranged opposite the oil through hole 111, and the design size of the oil through hole 111 is larger than the size of the first oil inlet 321, so that part of the outer wall of the heating core component 30 provided with the first oil inlet 321 is exposed from the oil through hole 111. Therefore, the user can observe the first oil inlet 321 through the light-transmitting area 13. This helps the user to judge whether the first oil inlet 321 is soaked in oil when the amount of oil is small. It is more accurate to judge the uniformity of oil adsorption. When the first oil inlet 321 is not soaked in oil, oil can be injected into the oil storage cavity 11 to prevent the oil-conducting material inside the heating core component 30 from burning, which is beneficial to extend the service life of the heating core component 30 and effectively improve the user experience.

[0039] It is understandable that the oil injection method can be a conventional oil filling hole and a sealing plug opening and closing method, or the oil can be directly injected into the oil storage chamber 11 after the atomizer base is disassembled, etc., which will not be elaborated here.

[0040] Specifically, the second oil inlet 322 is provided at the bottom of the heating core 30 along the gravity direction, so that the oil at the bottom of the atomizing section 122 can be effectively adsorbed, thereby preventing a large amount of oil from accumulating at the bottom of the atomizing section 122 .

[0041] Specifically, the diameter of the first oil inlet 321 is smaller than that of the second oil inlet 322. The oil at the top of the oil collecting space 1223 is drawn into the interior of the heating core 30 through the first oil inlet 321 by gravity. The oil at the bottom of the oil collecting space 1223 needs to overcome gravity before being drawn into the interior of the heating core 30 through the second oil inlet 322 for atomization. This further ensures that the oil guide 31 of the heating core 30 evenly absorbs the oil in the oil collecting space 1223, preventing the oil guide 31 from burning.

[0042] It is understandable that a plurality of oil inlets (not shown) may be spaced apart between the top and bottom of the heating core 30 in the direction of gravity to further enhance the adsorption rate and uniformity of the oil.

[0043] Specifically, if Figure 3 As shown, in one embodiment of the present invention, the main body 10 is provided with an oil storage chamber 11, a mounting pocket 15 located at the bottom of the oil storage chamber 11, and a suction section 121 located on one side of the oil storage chamber 11. The interior space of the mounting pocket 15 communicates with the suction section 121 to form the atomization section 122. The heating core 30 is inserted into the mounting pocket 15 and spaced apart from the inner wall of the atomization section 122 formed within the mounting pocket 15 to form an oil collection space 1223. The multiple oil inlet holes connect the oil collection space 1223 to the internal oil circuit of the heating core 30. By spacing the heating core 30 from the inner wall of the atomization section 122 to form the oil collection space 1223, each circumferentially spaced oil inlet of the heating core 30 can simultaneously absorb oil. This ensures that the oil absorbed within the heating core 30 is relatively uniform, thereby preventing the oil-conducting material within the heating core 30 from burning.

[0044] Specifically, if Figure 1 or Figure 2 As shown, in an embodiment of the present invention, the heating core component 30 includes a second part provided with the oil inlet and a first part and a third part located at opposite ends of the second part; when the heating core component 30 is installed on the main body 10, the outer peripheral surface of the first part and the outer peripheral surface of the third part are both interference fit with the inner wall of the atomization section 122; the outer peripheral surface of the second part is spaced apart from the atomization section 122 to form the oil collecting space 1223; the main body 10 is provided with an oil hole 111 on the inner wall of the second part corresponding to the oil storage chamber 11 to connect the oil storage chamber 11 with the oil collecting space 1223.

[0045] This time, in this embodiment, the shapes of the two ends of the heating core component 30 are adapted to the corresponding positions of the atomizing section 122 to form the first part and the third part. During installation, the heating core component 30 is inserted into the mounting pocket 15 so that the two ends of the heating core component 30 are interference fit with the atomizing section 122, so that the heating core component 30 is firmly mounted on the mounting pocket 15, without the need to use snap fasteners or other means for connection, and installation and disassembly are relatively convenient. The multiple oil inlets are opened in the second part of the main body 10. Because the first and third parts of the heating core are interference fit with the atomizing section 122, the second part and the atomizing section 122 are spaced apart to form a closed oil collection space 1223, which effectively prevents oil from flowing out of the gap between the first part or the second part and the atomizing section 122.

[0046] Specifically, if Figure 1 As shown, in an embodiment of the present invention, the atomizing section 122 includes a wide diameter section 1221 and two narrow diameter sections 1222 located at opposite ends of the wide diameter section 1221. The main body 10 is provided with the oil hole 111 on the inner wall between the wide diameter section 1221 and the oil storage chamber 11, so that the oil storage chamber 11 and the wide diameter section 1221 are in oil communication. When the heating core component 30 is installed on the main body 10, the first and third parts of the heating core component 30 are respectively interference fit with the inner walls of the two narrow diameter sections 1222, and the second part of the heating core component 30 is accommodated in the wide diameter section 1221, and forms the oil collecting space 1223 between the second part and the inner wall of the wide diameter section 1221. Here, in this embodiment, the main body 10 is made of plastic material, and the outer periphery of the heating core component 30 is made of metal material, which effectively prevents damage from high temperature. Furthermore, by providing the wide diameter section 1221 and the narrow diameter sections 1222 at both ends of the wide diameter section 1221 on the main body 10 to tightly fit the heating core 30, it is unnecessary to perform extensive processing on the heating core 30 made of metal, thereby effectively saving costs.

[0047] It is understandable that in actual application, it is not limited to the above embodiment, and the main body 10 is provided with a wide diameter section 1221 and a narrow diameter section 1222 to be interference-fitted with the heating core component 30. For example, in other embodiments of the present invention, the outer diameters of the first part and the third part of the heating core component 30 may be larger than the outer diameter of the second part, so that when the heating core component 30 is installed on the main body 10, the first part and the third part of the heating core component 30 are interference fit with the inner wall of the atomization section 122, and the second part of the heating core component 30 is spaced apart from the inner wall of the atomization section 122 to form the oil collection space 1223; for example, in another embodiment of the present invention, the atomization section 122 may include a wide diameter section 1221 and a narrow diameter section 1222 connected to the wide diameter section 1221, the outer diameter of the first part is larger than the inner diameter of the narrow diameter section 1222, the outer diameter of the second part is smaller than the inner diameter of the wide diameter section 1221; the outer diameter of the third part is larger than the inner diameter of the wide diameter section 1221, etc., to achieve the fixing of the heating core component 30 to the atomization section 122 and form the oil collection gap, all of which fall within the protection scope of the present invention.

[0048] At the same time, it can be understood that the diameter of each oil inlet is smaller than the diameter of the gas path inside the heating core 30. Therefore, when the atomizing gas path 3321 inside the heating core 30 extends along the axial direction of the heating core 30, the multiple oil inlets are spaced apart along the circumference of the heating core 30. During the user's inhalation process, the gas flow rate in the atomizing gas path 3321 is relatively high, and the multiple oil inlets arranged circumferentially on the heating core component 30 will produce a Venturi effect. Since the inner diameters of the first and third parts of the heating core component 30 are larger than the inner diameter of the second part, when the gas or liquid flows through the second part of the heating core component 30, the speed reaches the maximum value and the static pressure reaches the minimum value. The speed of the gas increases due to the reduction of the cross-sectional area of the flow. The gas flow must experience the process of reducing the inner diameter of the heating core component 30 at the same time, so the pressure also decreases at the same time, thereby generating a pressure difference. The pressure difference is used to provide an external suction force to the gas fluid, which can effectively improve the adsorption rate of the oil guide component 31 of the heating core component 30 on the oil collection space 1223.

[0049] Specifically, in this embodiment of the present invention, the curved connection between the atomizing section 122 and the suction section 121 effectively prevents splashing liquid from directly entering the user's mouth. However, this also causes the liquid to accumulate in the curved section 123, which can easily produce a gurgling sound during inhalation or be inhaled into the user's mouth, causing discomfort.

[0050] Therefore, in this embodiment, the heating core 30 includes a heating component 33 and an oil guide 31. The heating component 33 and the oil guide 31 are both housed within the atomizing section 122 and in contact with each other, so as to absorb and transfer the smoke liquid within the atomizing section 122 to the heating component 33. The oil guide 31 is also provided with an adsorption portion, which is located on the bottom wall at the intersection of the bending section 123 and the atomizing section 122 along the direction of gravity. When a certain amount of oil-water mixture condenses and gathers on the bottom wall, the adsorption portion can promptly adsorb the oil-water mixture onto the oil guide 31, preventing it from agglomerating and being inhaled into the user's mouth, causing discomfort, thereby providing the user with a good user experience. Furthermore, through adsorption by the adsorption portion, the oil in the oil-water mixture can be recovered and re-atomized, effectively reducing oil waste.

[0051] Specifically, the caliber of the atomizing section 122 is larger than the caliber of the bending section 123, so that a step 124 is formed at the intersection of the atomizing section 122 and the bending section 123 along the direction of gravity. The step 124 includes a first surface 1241 along the direction of gravity and a second surface 1242 arranged at an angle to the direction of gravity. The height of the first surface 1241 of the step 124 along the direction of gravity is greater than or equal to the height of the lowest point of the adsorption part along the direction of gravity, thereby ensuring that the adsorption part can always adsorb the oil-water mixture on the bottom wall along the direction of gravity at the intersection of the bending section 123 and the atomizing section 122, and the use effect is good.

[0052] Specifically, if Figure 2 As shown, in an embodiment of the present invention, the adsorption portion is at least partially in close contact with the first surface 1241 of the step 124, thereby preventing the oil-water mixture on the bottom wall at the intersection of the bending section 123 and the atomization section 122 along the direction of gravity from leaking from the side of the adsorption portion into the atomization section 122, thereby ensuring the cleanliness of the atomization section 122.

[0053] It can be understood that, in actual application, the adsorption portion can also partially extend to the second surface 1242, effectively improving the oil absorption effect of the adsorption portion, thereby preventing the oil-water mixture on the bottom wall at the intersection of the bending section 123 and the atomization section 122 along the gravity direction from leaking from the bottom of the adsorption portion to the first surface 1241, thereby preventing the oil from accumulating on the second surface 1242.

[0054] It is understood that in actual applications, the method of extending the adsorption portion to the second surface 1242 to prevent oil from accumulating on the second surface 1242 is not limited to the above-mentioned embodiment. For example, in other embodiments of the present invention, the end where the second surface 1242 intersects with the suction section 121 may be arranged higher than the end where the second surface 1242 intersects with the first surface 1241 to form a guide surface that guides condensed liquid from the suction section 121 to the first surface 1241. In this way, the oil-water mixture condensed on the second surface 1242 and the side wall of the suction section 121 can flow toward the first surface 1241 under the action of gravity, so that the adsorption portion can perform timely adsorption and prevent oil from accumulating.

[0055] Specifically, if Figure 2 As shown, in the embodiment of the present invention, the heating core component 30 further includes a first bracket 32. The oil guide component 31 is covered on the outer peripheral surface of the heating component 33. The first bracket 32 is arranged around the outer periphery of the oil guide component 31, thereby supporting the oil guide component 31 to have a fixed spatial shape. This can facilitate uniform distribution of oil on the oil guide component 31. The end surface of one end of the oil guide component 31 is exposed from the end surface of one end of the first bracket 32 to form an adsorption portion to adsorb the gathered oil and prevent aggregation.

[0056] When the heating core component 30 is installed on the main body 10, one end of the first bracket 32 is inserted into the atomization section 122 and abuts against the first surface 1241 to form a positioning installation. In this way, during installation, it is only necessary to install the first bracket 32 until it abuts against the first surface 1241, which is convenient for installation. The first bracket 32 is provided with an oil inlet to conduct the smoke liquid in the atomization section 122 to the oil guide component 31, thereby ensuring that there is a continuous supply of oil on the oil guide component 31 for the user to inhale.

[0057] Specifically, if Figure 2 As shown, in an embodiment of the present invention, the oil guide member 31 is arranged in an annular shape, and has a first outer annular surface and a first inner annular surface in the radial direction of the oil guide member 31. The lowest point of the first outer annular surface is flush with the lowest point of the second surface 1242. This can ensure that the oil accumulated on the second surface 1242 is adsorbed by the adsorption part to prevent oil leakage.

[0058] Alternatively, as a different embodiment, the oil guide member 31 has a first outer annular surface and a first inner annular surface in the radial direction, and the lowest point of the second surface 1242 is located between the first outer annular surface and the first inner annular surface. The position of the oil guide member 31 is placed in this way, which can also ensure that the oil gathered on the second surface 1242 is adsorbed by the adsorption part to prevent oil leakage.

[0059] Alternatively, as a different embodiment, the oil guide member 31 has a first outer annular surface and a first inner annular surface in the radial direction, and the first inner annular surface is flush with the side of the second surface 1242 close to the oil guide member 31. The position of the oil guide member 31 is placed in this way, which can also ensure that the oil accumulated on the second surface 1242 is adsorbed by the adsorption part to prevent oil leakage.

[0060] Furthermore, if Figure 2 As shown, in an embodiment of the present invention, the heating component 33 includes a second bracket 331, an oil-absorbing member 333 and a heating member 332. An atomizing airway is provided in the heating member 332 for the smoke generated by atomization to flow to the intersection section, and then flow out to the suction section 121 for the user to inhale; the oil-absorbing member 333 is covered on the outer periphery of the heating member 332, the second bracket 331 is arranged around the outer periphery of the oil-absorbing member 333, and the oil-guiding member 31 is covered on the outer periphery of the second bracket 331. The oil-absorbing member 333 is used to absorb the oil output from the oil storage chamber 11 absorbed by the oil-guiding member 31, and then supply it to the heating member 332 for atomization treatment, wherein the second bracket 331 is used to support the oil-absorbing member 333 and the oil-guiding member 31, so that it has good oil absorption and oil guiding effects.

[0061] Specifically, if Figure 2 As shown, in the embodiment of the present invention, the oil suction member 333 is arranged in an annular shape, and the radial direction of the oil suction member 333 has a second outer annular surface and a second inner annular surface, and the lowest point of the second outer annular surface is flush with the lowest point of the second surface 1242. As a different embodiment, the position of the oil guide member 31 is placed in this way, which can also ensure that the oil accumulated on the second surface 1242 is adsorbed by the adsorption part to prevent oil leakage.

[0062] Alternatively, as a different embodiment, the oil absorbing member 333 has a second outer annular surface and a second inner annular surface in the radial direction, and the lowest point of the second surface 1242 is located between the second outer annular surface and the second inner annular surface. Such placement of the oil absorbing member 333 can also ensure that the oil accumulated on the second surface 1242 is adsorbed by the adsorption portion to prevent oil leakage.

[0063] Alternatively, as a different embodiment, the oil absorbing member 333 has a second outer annular surface and a second inner annular surface in the radial direction, and the second inner annular surface is flush with the side of the second surface 1242 close to the oil absorbing member 333. Such placement of the oil absorbing member 333 can also ensure that the oil accumulated on the second surface 1242 is absorbed by the adsorption portion to prevent oil leakage.

[0064] In one embodiment, Figure 2 As shown, the heating element 332 is in a spiral or annular mesh shape, which is conducive to the atomization of the oil and improves the atomization efficiency of the oil.

[0065] In one embodiment, Figure 2As shown, the suction port 14 is directly opposite to the intersection of the suction section 121 and the bending section 123, which is conducive to the flow of smoke into the user's mouth, giving the user a good user experience;

[0066] Or, as Figure 2 As shown, in an embodiment of the present invention, as a different implementation method, the inner wall of the suction section 121 facing the suction port 14 is inclined, and the lower part of the inclination is toward the intersection of the suction section 121 and the bending section 123 to form an oil guide surface 1243 to guide the condensate and saliva to the bending section 123, thereby preventing oil from accumulating in the air path facing the suction port 14.

[0067] Specifically, the angle range between the connecting line of the bottom of the light-transmitting area 13 along the gravity direction and the center of the hole of the first oil inlet 321 and the horizontal plane where the first oil inlet 321 is located is 30° to -30°. The setting height of the light-transmitting area 13 is controlled within this range, which effectively prevents the light-transmitting area 13 from being set too high, resulting in weak light at the bottom of the oil storage cavity 11, which is inconvenient for users to observe, thereby ensuring that users can observe whether the first oil inlet 321 of the heating core component 30 can be soaked in oil through the light-transmitting area 13.

[0068] Specifically, the bottom of the light-transmitting area 13 is located at a level with the horizontal plane where the first oil inlet 321 of the heating core 30 is located; or, the bottom of the light-transmitting area 13 is located below the horizontal plane where the first oil inlet 321 of the heating core 30 is located, along the direction of gravity. In this case, the light-transmitting area 13 completely exposes the bottom of the oil storage cavity 11 within the heating core 30 to the outside world. This allows the user to more clearly observe through the light-transmitting area 13 whether the first oil inlet 321 of the heating core 30 is soaked with oil, and to better judge the remaining amount of oil in the oil storage cavity 11.

[0069] It is understandable that, in actual application, it is not limited to the above-mentioned embodiment that the bottom of the light-transmitting area 13 is flush with the horizontal plane where the first oil inlet 321 of the heating core 30 is located. For example, in other embodiments of the present invention, the bottom of the light-transmitting area 13 can also be flush with the bottom wall of the oil storage cavity 11, or slightly higher than the bottom wall of the oil storage cavity 11, and the height above the bottom wall satisfies the angle between the connecting line of the bottom of the light-transmitting area 13 along the gravity direction and the center of the hole of the first oil inlet 321 and the horizontal plane where the first oil inlet 321 is located, which is in the range of 30° to -30°, such as 15°, 10°, 5°, etc., so that the bottom wall of the oil storage cavity 11 is sufficiently illuminated for the user to observe, which falls within the protection scope of the present invention.

[0070] Specifically, to prevent the phenomenon of having only a single light-transmitting area 13 on the main body 10, which would result in a dark interior and limited viewing angle, in this embodiment, light-transmitting areas 13 are provided on both sides of the main body 10 corresponding to the oil reservoir 11. Furthermore, to further enhance light transmission, the two light-transmitting areas 13 are positioned opposite each other on the two side walls of the main body 10, thereby increasing the amount of light entering.

[0071] It will be appreciated that in actual applications, the method of enhancing light penetration by using two oppositely disposed light-transmitting areas 13 is not limited to the above-described embodiment. For example, to further enhance light penetration and facilitate user viewing, the number of light-transmitting areas 13 can be increased according to user needs, such as three, four, five, or six, with the multiple light-transmitting areas 13 spaced apart along the periphery of the main body 10. Methods that ensure light penetration and enable users to observe the oil from any surface also fall within the scope of protection of the present invention.

[0072] The present invention further provides an electronic cigarette 1000, which includes a power supply device 200 and an atomization device 100. The specific structure of the atomization device 100 refers to the above embodiment. Since the electronic cigarette 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described one by one here.

[0073] Among them, Figure 3 As shown, in an embodiment of the present invention, the power supply device 200 is provided with a mounting cavity 210 for partially plugging in the atomizer device 100 of the electronic cigarette 1000, and the power supply device 200 is further provided with a window 220 on the cavity wall of the mounting cavity 210; when the atomizer device 100 of the electronic cigarette 1000 is installed in the mounting cavity 210 of the power supply device 200, the light-transmitting area 13 is exposed from the window 220, and observation is performed through the window 220 on the cavity wall of the mounting cavity 210 of the power supply device 200 and through the light-transmitting area 13 on the main body 10 of the atomizer device 100. The setting position of the window 220 corresponds to the setting position of the light-transmitting area 13, ensuring that the user can observe whether the first oil inlet 321 of the heating core component 30 can be soaked in oil through the window 220 on the cavity wall of the mounting cavity 210 of the power supply device 200 and through the light-transmitting area 13 on the main body 10 of the atomizer device 100.

[0074] Furthermore, if Figure 3As shown, in this embodiment of the present invention, the light-transmitting area 13 protrudes from the surface of the main body 10. The end of the window 220 that opens toward the mounting cavity 210 forms an insertion port for the light-transmitting area 13. This ensures that the user can observe whether the first oil inlet 321 of the heating core 30 is immersed in oil through the light-transmitting area 13 on the main body 10. This also facilitates assembly and disassembly of the atomizer 100 and the power supply 200. When the atomizer 100 of the electronic cigarette 1000 is installed in the mounting cavity 210 of the power supply 200, the end surface of the protruding end of the light-transmitting area 13 is flush with the outer surface of the power supply 200, making the electronic cigarette 1000 more aesthetically pleasing and enhancing the user experience. Alternatively, the end surface of the protruding end of the light-transmitting area 13 protrudes from the outer surface of the power supply 200, making it easier for the user to assemble and disassemble the electronic cigarette 1000.

[0075] The above description is only a preferred embodiment of this embodiment and is not intended to limit this embodiment. Any modifications, equivalent replacements and improvements made within the spirit and principles of this embodiment should be included in the scope of protection of this embodiment.
