Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of atomization, in particular to an atomization core and an electronic atomization device. BACKGROUND

[0002] The electronic atomization device, also known as an electronic cigarette, is a device that generates aerosol by heating and atomizing an atomization medium (such as tobacco tar) for a user to smoke, thereby simulating the feeling of smoking. As a substitute for cigarettes, the electronic atomization device is very popular among smokers. A conventional electronic atomization device is composed of an atomization assembly and a power assembly. The atomization assembly has an oil storage cavity and an atomization core inside. The atomization medium (such as tobacco tar) is stored in the oil storage cavity. The power assembly supplies power to the atomization core to heat and atomize the tobacco tar in the oil storage cavity to generate aerosol for the user to smoke.

[0003] In the prior art, the atomization core of most electronic atomization devices includes a heating element and a first oil guide. The first oil guide is wrapped around the outside of the heating element and is in communication with the oil storage cavity to guide the flow of tobacco tar in the oil storage cavity to the surface of the heating element, thereby serving as an oil guide medium. However, most current oil guiding methods involve oil flowing in from both sides of the first oil guide, which results in uneven and slow oil guiding. In addition, during the user's smoking process, the tobacco tar in the oil storage cavity diffuses to the surface of the heating element. As the tobacco tar is continuously consumed, negative pressure is generated in the oil storage cavity. When the negative pressure is too high, the tobacco tar cannot reach the surface of the heating element smoothly, which causes the first oil guide in direct contact with the heating element to burn and fail due to the high temperature, thereby producing a stimulating burnt taste, or causing the smoking taste to weaken quickly and the remaining amount of tobacco tar to be large, which affects the service life of the electronic atomization device and the user's smoking experience.

[0046] Referring to Figures 1 to 2 , Figure 1 Fig. 1 shows a schematic view of the appearance of an electronic atomizing device 10 in an embodiment of the present application, Figure 2 Fig. 2 shows a top view of the electronic atomizing device 10 in an embodiment of the present application, Figure 3An internal structure cross-sectional view of the electronic atomization device 10 in this embodiment is shown. The electronic atomization device 10 provided by an embodiment of the present application includes a housing 100, an oil storage assembly 200, an atomization core 300, and a power supply assembly 400, wherein the housing 100 is provided with an air inlet hole 101 and an air outlet hole 102 that are in communication with each other; the oil storage assembly 200, the atomization core 300, and the power supply assembly 400 are arranged in the housing 100, the oil storage assembly 200 is configured to store tobacco tar, the atomization core 300 is arranged inside the oil storage assembly 200 and is electrically connected to the power supply assembly 400, and the power supply assembly 400 is configured to supply power to the atomization core 300, so that the atomization core 300 can heat and atomize the tobacco tar to generate aerosol under the action of the power supplied by the power supply assembly 400.

[0047] Specifically, refer to Figure 3 In one embodiment, the power supply assembly 400 includes a bracket 410, a battery 420, and an airflow sensor 430, the bracket 410 has a first mounting position 411, a second mounting position 413, and a ventilation cavity 412, the first mounting position 411 is located close to the air inlet hole 101 and is in communication with the ventilation cavity 412, the second mounting position 413 is isolated from the ventilation cavity 412, the airflow sensor 430 is arranged in the first mounting position 411, and the battery 420 is arranged in the second mounting position 413, the battery 420 is electrically connected to the airflow sensor 430 and to the atomization core 300.

[0048] When a user inhales, external air flows into the air inlet hole 101, passes through the first mounting position 411, and flows into the atomization core 300, the airflow sensor 430 detects the airflow and determines that it is an inhaling action, and the controller controls the battery 420 to supply power to the atomization core 300, so that the atomization core 300 can heat the tobacco tar temporarily stored in its own interior to generate aerosol, the generated aerosol is mixed with the external air flowing in, and is discharged from the air outlet hole 102 for the user to inhale.

[0049] Further, please continue to refer to Figure 3In one embodiment, the oil storage assembly 200 comprises an inner shell 210, a first seal 220, a second seal 230, and a breather tube 240, wherein the first seal 220 and the second seal 230 respectively seal the opposite ends of the inner shell 210, the first seal 220 is connected to the support 410 of the power supply assembly 400, the second seal 230 is arranged opposite to the first seal 220 and close to the air outlet hole 102, one end of the breather tube 240 is connected to the first seal 220, and the other end of the breather tube 240 is connected to the second seal 230, so that the inner wall of the inner shell 210, the outer wall of the breather tube 240, the side of the first seal 220 facing the second seal 230, and the side of the second seal 230 facing the first seal 220 form an oil storage cavity 201; in other embodiments, the oil storage cavity 201 further comprises an oil storage cotton 250, and the tobacco tar is adsorbed in the oil storage cotton 250; the breather tube 240 is provided with an air passage 241 penetrating through the opposite ends of the breather tube 240, the air passage 241 is in communication with the air inlet hole 101 and the air outlet hole 102; the atomizing core 300 is connected to the breather tube 240 and in communication with the oil storage cavity 201, and the atomizing core 300 is further electrically connected to the battery 420, and the tobacco tar is adsorbed in the oil storage cotton 250. When the user smokes, the tobacco tar stored in the oil storage cavity 201 flows to the atomizing core 300 and is atomized by the atomizing core 300.

[0050] In a preferred embodiment, the oil storage cotton 250 is preferably made of flax cotton or oil-impregnated cotton, which has good oil storage and locking capacity, can quickly absorb and store tobacco tar, and effectively prevents tobacco tar leakage.

[0051] Referring to Figure 4 and Figure 5 In the structure of the atomizing core 300, the atomizing core 300 comprises a first oil guide 310 and a heating element 320, the first oil guide 310 is in a hollow cylindrical structure, so that an atomizing cavity 310a is formed in the first oil guide 310, the heating element 320 is wrapped in the first oil guide 310 and arranged in the atomizing cavity 310a, and the atomizing cavity 310a is in communication with the air inlet hole 101, the air passage 241, and the air outlet hole 102. The first oil guide 310 is used to adsorb tobacco tar from the oil storage cavity 201 and guide the tobacco tar to the heating element 320 in the atomizing cavity 310a, so that the heating element 320 can heat and atomize the tobacco tar to generate aerosol. Exemplarily, the first oil guide 310 is preferably oil guide cotton, which is usually made of flax, non-woven fabric, or seaweed cotton, and is usually in a long strip shape before assembly; the first oil guide 310 can also be other porous oil guide materials such as porous ceramics. It can be understood that the above-mentioned materials for the first oil guide 310 usually have strong lipophilicity and adsorbability, the material itself has countless tiny pores, can quickly adsorb and transport tobacco tar, and can work stably at a high temperature.

[0052] As described in the background, most of the current oil guiding methods are to guide oil from both sides of the first oil guiding member 310, so that the oil guiding is uneven and slow. As described above, during the user's puffing process, the tobacco oil spreads from the oil storage cavity 201 to the surface of the heating member 320. As the tobacco oil is continuously consumed, the oil storage cavity 201 will generate a negative pressure. When the negative pressure is too high, the tobacco oil cannot reach the surface of the heating member 320 smoothly, so that the first oil guiding member 310 in direct contact with the heating member 320 is burned and fails due to the high temperature, thereby causing problems such as irritating burnt taste, weak puffing taste, and large amount of remaining oil, which affect the service life of the electronic atomization device 10 and the user's puffing experience.

[0053] To solve this problem, as shown in Figure 3 、 Figure 6 、 Figure 7 the first oil guiding member 310 is provided with a gas guiding hole 310b and / or a gas guiding groove 310c (as shown in Figure 6 the embodiment shown in the figure, the first oil guiding member 310 is provided with a gas guiding hole 310b, Figure 7 the embodiment shown in the figure, the first oil guiding member 310 is provided with a long strip-shaped gas guiding groove 310c); after assembly, the atomization cavity 310a is in communication with the oil storage cavity 201 through the gas guiding hole 310b and / or the gas guiding groove 310c. When the user puffs, the atomization cavity 310a generates aerosol and mixes with the air flowing into the atomization cavity 310a, and is sucked out by the user through the air outlet hole 102. In this process, due to the airflow formed in the atomization cavity 310a, a negative pressure is generated. Since the atomization cavity 310a is in communication with the oil storage cavity 201, under the action of the negative pressure in the atomization cavity 310a, the tobacco oil inside the oil storage cavity 201 will flow to the first oil guiding member 310 at a faster speed and be quickly supplied to the heating member 320, so as to ensure that there is sufficient tobacco oil for atomization in the next operation, thereby avoiding problems such as insufficient tobacco oil supply and dry burning, and decay of puffing taste. When the user stops puffing, the air in the atomization cavity 310a will be supplemented into the oil storage cavity 201 through the gas guiding hole 310b and / or the gas guiding groove 310c, so as to balance the negative pressure generated in the oil storage cavity 201 due to the consumption of the tobacco oil. These two processes are alternately performed with the user's puffing, which can not only avoid the generation of negative pressure in the oil storage cavity 201, but also ensure that the tobacco oil can always be supplied to the first oil guiding member 310 at the fastest speed during each use of the user.

[0054] In a preferred embodiment, the oil storage cotton 250 is in contact with the outer surface of the first oil guiding member 310, so as to transmit the tobacco oil to the first oil guiding member 310.

[0055] Further, referring to Figure 8The oil storage assembly 200 further comprises a second oil guide 340 arranged between the oil storage cotton 250 and the first oil guide 310, the second oil guide 340 is attached to the outer surface of the first oil guide 310 and the inner surface of the oil storage cotton 250 respectively to increase the tightness of the contact among the three, thereby improving the stability of the tobacco tar transmission. The material of the second oil guide 340 can be flax, non-woven fabric or seaweed cotton.

[0056] In other preferred embodiments, for the convenience of assembly, as shown in Figure 4 and Figure 5 The atomizing core 300 further comprises an oil guide seat 330, the oil guide seat 330 is provided with an oil inlet hole 330a with an inner wall and an outer wall, the first oil guide 310 is fixedly connected to the oil guide seat 330 and is at least partially arranged in the oil guide seat 330, the tobacco tar in the oil storage cavity 201 can flow to the first oil guide 310 through the oil inlet hole 330a and then be guided by the first oil guide 310 to the heating element 320. In the embodiment shown in the figure, the oil guide seat 330 is integrally connected with the air tube 240. In other embodiments, the oil guide seat 330 and the air tube 240 are separate structures, one end of the oil guide seat 330 is connected to one end of the air tube 240, specifically, the air tube 240 can be sleeved on the end of the oil guide seat 330 or the oil guide seat 330 can be sleeved on the end of the air tube 240, which is not limited here.

[0057] On this basis, in order to facilitate the tobacco tar to flow from the oil storage cotton 250 to the first oil guide 310, part of the first oil guide 310 is located in the oil guide seat 330 and the other part extends out of the oil guide seat 330 and is located in the oil storage cavity 201, when the oil storage cavity 201 is provided with the oil storage cotton 250, the part of the first oil guide 310 located in the oil storage cavity 201 is embedded in the oil storage cotton 250. Specifically, in one embodiment, the oil guide seat 330 is provided with a mounting groove 330b with an inner wall and an outer wall, the first oil guide 310 comprises a cylindrical hollow body 311 and an oil guide lug 312 connected to the body 311, the body 311 is attached to the inner wall of the oil guide seat 330, and the oil guide lug 312 extends out of the oil guide seat 330 along the radial direction of the body 311.

[0058] In this way, the oil guide lug 312 extending out of the oil guide seat 330 is embedded in the oil storage cotton 250, which can further increase the contact area between the first oil guide 310 and the oil storage cotton 250, thereby improving the speed of the tobacco tar transmission to the first oil guide 310.

[0059] In addition, referring to Figure 8, the air tube 240 and the oil guide base 330 are arranged in the inner shell 210 to form the oil storage cavity 201 with the inner wall of the inner shell 210. Inevitably, the oil storage cotton 250 in the oil storage cavity 201 cannot be completely and tightly attached to the outer wall of the air tube 240 or the oil guide base 330, and thus the oil storage cotton 250 can have a gap with the outer wall of the air tube 240 or the oil guide base 330, and the tobacco tar can not flow smoothly to the first oil guide 310.

[0060] To solve this problem, in other preferred embodiments, the second oil guide 340 is arranged between the oil guide base 330 and the oil storage cotton 250. Preferably, the second oil guide 340 is wrapped around the outer surface of the oil guide base 330 and covers the oil inlet hole 330a, and another surface of the second oil guide 340 is attached to the inner surface of the oil storage cotton 250, thereby increasing the tightness of the attachment of the three to improve the stability of the tobacco tar transmission. The material of the second oil guide 340 can be linen, non-woven fabric or seaweed cotton.

[0061] In other preferred embodiments, the second oil guide 340 is also provided with a through hole or a through groove, which is at least partially communicated with the air guide hole 310b and / or the air guide groove 310c on the first oil guide 310 to ensure the smoothness of the communication between the atomization cavity 310a and the oil storage cavity 201. Of course, in order to ensure that the first oil guide 310 is in close contact with the oil storage cotton 250 through the oil inlet hole 330a, the air guide hole 310b or the air guide groove 310c can not be provided on the second oil guide 340, and there is no particular limitation.

[0062] It can be understood that the first oil guide 310 can also be provided with the air guide hole 310b and the air guide groove 310c at the same time; it can also be understood that the air guide hole 310b can be provided in multiple numbers, and the specific number is not limited, and the multiple air guide holes 310b are distributed in a matrix, or the air guide groove 310c is provided with multiple rows or multiple columns to enhance the oil guiding effect.

[0063] It should be noted that the air guide hole 310b and the air guide groove 310c are different from the micropores of the first oil guide 310 itself, that is, the hole diameter of the air guide hole 310b or the groove width of the air guide groove 310c is much larger than the micropore diameter of the first oil guide 310 itself. Preferably, the hole diameter of the air guide hole 310b is 0.5mm-3mm, or the groove width of the air guide groove 310c is 0.5mm-3mm, which can ensure that the tobacco tar can flow quickly and stably to the heating element 320, and also can avoid the situation that the tobacco tar leaks due to too fast flow.

[0064] More preferably, in combination with Figure 5 and Figure 9As shown, the projection of at least one air guide hole 310b and / or at least part of the air guide groove 310c on the inner wall of the oil guide seat 330 is located inside the oil inlet hole 330a, that is, at least one air guide hole 310b and / or at least part of at least one air guide groove 310c is located opposite to the oil inlet hole 330a, so that the communication between the atomization chamber 310a and the oil storage chamber 201 can be ensured.

[0065] In terms of the structure of the heating element 320, the heating element 320 can be a spiral heating wire, or a mesh heating net or other special-shaped heating sheet. Regardless of whether the heating element 320 is a heating wire, a heating net or a heating sheet, the heating element 320 includes a heating portion 321 (i.e., the portion where the working current mainly flows and can generate a large amount of heat), and the air guide holes 310b and / or the air guide grooves 310c are arranged to avoid the heating portion 321.

[0066] For example, when the heating element 320 is a spiral heating wire, the air guide hole 310 b and / or the air guide groove 310 c are located at the spiral gap, thereby avoiding the heating portion 321 .

[0067] When the heating element 320 is a mesh heating net or other special-shaped heating sheet, such as Figure 9 As shown, the heating element 320 includes a heating portion 321 (the portion through which the working current mainly flows and can generate a large amount of heat) and a heat-conducting portion 322 (the portion through which the non-working current mainly flows, which mainly transfers the heat generated by the heating portion 321 to other parts of the heating element, thereby uniformly heating). A gap is formed between the heating portion 321 and the heat-conducting portion 322, and the air guide holes 310b and / or the air guide grooves 310c can be positioned in the gap, or the air guide holes 310b and / or the air guide grooves 310c can be arranged at the position of the heat-conducting portion 322, so that the air guide holes 310b and / or the air guide grooves 310c avoid the heating portion 321.

[0068] This design is intended because the heating portion 321 forms the passageway, generating significant heat and atomizing the e-liquid into aerosol. To prevent dry burning, the heating portion 321 typically needs to fit tightly against the first e-liquid guide 310 to ensure adequate contact with the e-liquid. If the air guide holes 310b and / or air guide grooves 310c correspond to or partially correspond to the heating portion 321, the corresponding portion of the heating portion 321 will not fit tightly against the first e-liquid guide 310 due to the presence of the holes or grooves, preventing adequate contact with the e-liquid and potentially leading to dry burning.

[0069] exist Figure 9In the embodiment shown in , the heating element 320 is in a mesh shape and includes a heating portion 321 and a heat-conducting portion 322. The heat-conducting portion 322 is used to conduct the heat generated by the heating portion 321. Specifically, in the axial direction of the heat-conducting portion (the X direction shown in the figure), the heating portion 321 and the heat-conducting portion 322 are arranged alternately at intervals. Each group of heating portions 321 includes a plurality of heating strips 321a arranged at intervals along the circumference of the first oil-conducting portion 310 (the Y direction shown in the figure). Each group of heat-conducting portions 322 includes a plurality of heat-conducting strips 322a arranged at intervals along the circumference of the first oil-conducting portion 310. All the heating strips 321a and all the heat-conducting strips 322a construct the heating element 320 in a mesh shape. More specifically, each heat-conducting strip 322a is arranged along the circumference of the first oil-conducting portion 310. The first oil guide 310 is provided with an axial extension, and each heating strip 321a is tilted relative to the axial direction of the first oil guide 310, and at least one end of each heating strip 321a is simultaneously connected to one end of the heat-conducting strip 322a and one end of an adjacent heating strip 321a, so that the two adjacent heating strips 321a are in a "V" shape or an inverted "V" shape. For example, as shown in the figure, the heating portion 321 has two groups and the heat-conducting portion 322 has three groups, and both ends of each heating strip 321a are simultaneously connected to one end of the heat-conducting strip 322a and one end of the adjacent heating strip 321a. Of course, the number of heating portions 321 and heat-conducting portions 322 is not limited, and each can have only one group or more than two groups, which is not limited here.

[0070] Furthermore, if Figure 8 As shown, the heating strip 321a and the heat-conducting strip 322a are composed of multiple mesh holes. In a preferred embodiment, the air guide hole 310b is located opposite the mesh hole, that is, the air guide hole 310b and the heating strip 321a and the heat-conducting strip 322a are all staggered. Of course, the air guide groove 310c and the heating strip 321a and the heat-conducting strip 322a can also be staggered. In this way, the air guide hole 310b and / or the air guide groove 310c will not be blocked by the heating strip 321a and the heat-conducting strip 322a, so that the air flow will not be completely blocked when passing through the air guide hole 310b and / or the air guide groove 310c, thereby enabling the first oil guide member 310 to have a better oil guiding effect.

[0071] It should be noted that, in actual situations, due to reasons of installation precision, the air guide holes 310b and / or the air guide grooves 310c may not necessarily be able to ensure that they are completely aligned with the mesh, that is, it is impossible to completely ensure that they avoid the thermal conductive strips 322a. However, as long as they are ensured to avoid the heating part 321, it can basically ensure smooth airflow, thereby preventing the heating element 320 from burning dry.

[0072] Also, see Figure 9, the air tube 240 and the oil guide base 330 are arranged in the inner shell 210 to form the oil storage cavity 201 with the inner wall of the inner shell 210. Inevitably, the oil storage cotton 250 in the oil storage cavity 201 cannot be completely and tightly attached to the outer wall of the air tube 240 or the oil guide base 330, so that the oil storage cotton 250 can have a gap with the outer wall of the air tube 240 or the oil guide base 330, and the tobacco tar can not flow smoothly to the first oil guide 310.

[0073] To solve this problem, the atomizing core 300 further comprises a second oil guide 340, which is arranged in the oil storage cavity 201 and wrapped around the oil guide base 330 and covers the oil inlet hole 330a. The inner wall of the second oil guide 340 is attached to the air tube 240 and the oil guide base 330, and the outer wall is attached to the oil storage cotton 250. The material of the second oil guide 340 can also be made of linen, non-woven fabric or seaweed cotton, etc. The thickness of the second oil guide 340 is thinner than that of the first oil guide 310, as long as the outer wall is attached to the oil storage cotton 250 and the inner wall is attached to the air tube 240 and the oil guide base 330, so that the tobacco tar in the oil storage cotton 250 can flow smoothly to the first oil guide 310 through the second oil guide 340.

[0074] It should be noted that when the air tube 240 and the oil guide base 330 are integrated, it can be understood that the oil guide base 330 is part of the air tube 240, the first oil guide 310 is arranged in the air tube 240, and the inner wall of the second oil guide 340 is attached to the outer wall of the air tube 240. When the air tube 240 and the oil guide base 330 are a split structure, the first oil guide 310 is arranged in the oil guide base 330, and the inner wall of the second oil guide 340 is attached to the outer wall of the air tube 240 and the oil guide base 330.

[0075] Further, the position of the second oil guide 340 on the oil inlet hole 330a of the oil guide base 330 can also be provided with the air guide hole 310b and / or the air guide groove 310c as the first oil guide 310, to ensure that air can flow into the oil storage cavity 201 to generate circulating air flow to pull the tobacco tar to flow quickly to the first oil guide 310. Of course, in order to ensure that the first oil guide 310 is in close contact with the oil storage cotton 250 through the oil inlet hole 330a, the air guide hole 310b or the air guide groove 310c can not be provided on the second oil guide 340, and there is no particular limitation.

[0076] Therefore, the atomization core 300 provided in the application sets the first oil guide 310 of the above-mentioned embodiments, so that when the user smokes, the airflow flowing from the air inlet hole 101 to the air channel 241 can quickly pull the tobacco tar on the oil storage cotton 250 to the first oil guide 310 and the heating element 320 through the air guide hole 310b and / or the air guide groove 310c of the first oil guide 310, ensuring that the heating element 320 is always fully supplied with tobacco tar, avoiding the problems of rapid attenuation of smoking taste, excessive residual oil, or easy production of irritating paste taste, which affects the service life of the electronic atomization device 10 and the smoking experience of the user.

[0077] The technical features of the above-mentioned embodiments can be combined in any way. In order to make the description simple, all possible combinations of the technical features in the above-mentioned embodiments are not described, but as long as the combination of the technical features does not exist contradictory, it should be considered as the scope of the present application.

[0078] The above-mentioned embodiments only express several implementation manners of the application, and the description is more specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the application, a number of modifications and improvements can be made, which are all within the protection scope of the application. Therefore, the protection scope of the patent of the application should be subject to the appended claims.
