Description

TECHNICAL FIELD

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

[0002] The electronic atomization device, also known as electronic cigarette, is a device for generating aerosol by heating and atomizing tobacco tar for a user to smoke, so as to simulate the feeling of smoking. As a substitute for cigarettes, the electronic atomization device is very popular among smokers. Generally, the electronic atomization device is composed of an atomization assembly and a power supply assembly. The atomization assembly has an oil storage chamber and an atomizing core inside. The tobacco tar is stored in the oil storage chamber. The power supply assembly is used to supply power to the atomizing core. The atomizing core is used to heat and atomize the tobacco tar in the oil storage chamber to generate aerosol for the user to smoke.

[0003] At present, the traditional atomizing core generally includes a porous ceramic oil guide and a heating element arranged on the oil guide. The heating element heats the oil guide by direct contact, so as to heat and atomize the tobacco tar in the oil guide. However, due to the small thermal conductivity coefficient of the porous ceramic, the heat conduction rate is slow, so that the surface temperature of the oil guide in contact with the heating element is high, while the temperature of the part of the oil guide far away from the heating element is low, which makes the preheating ability of the oil guide to the tobacco tar (especially to the tobacco tar far away from the heating element on the oil guide) poor, and the oil guiding rate slow. Therefore, it is difficult for such an atomizing core to atomize high-viscosity tobacco tar with large viscosity and poor flowability, and the burnt taste is easy to occur.

[0046] An embodiment of the present application provides an electronic atomization device for heating atomization medium stored inside itself to form an aerosol for a user to inhale.

[0047] The following will take the electronic atomization device as an example to illustrate the structure of the electronic atomization device in the present application. The present embodiment is only used as an example for illustration and will not limit the technical scope of the present application. It can be understood that in other embodiments, the electronic atomization device of the present application is not limited to an electronic cigarette, but can also be any electronic atomization device capable of atomizing an atomization medium into an aerosol, which is not limited herein.

[0048] Referring to Figures 1 to 4 , Figure 1 shows a schematic view of the appearance of the electronic atomization device 10 in an embodiment of the present application, Figure 2 shows a top view of the electronic atomization device 10, Figure 3 shows an exploded schematic view of the electronic atomization device 10, Figure 4 shows a cross-sectional view of the internal structure of the electronic atomization device 10. The electronic atomization device 10 provided in an embodiment of the present application comprises a housing 100, an atomization assembly 200 and a power supply assembly 300, wherein the atomization assembly 200 and the power supply assembly 300 are both arranged in the housing 100 and are connected to each other. The power supply assembly 300 is used to supply power to the atomization assembly 200, and the atomization assembly 200 is used to heat the atomization medium stored therein under the action of the electric energy provided by the power supply assembly 300, so that the atomization medium can be atomized to generate an aerosol for the user to inhale.

[0049] Specifically, in one embodiment, referring to Figure 4 , the housing 100 is provided with an air inlet 101 and an air outlet 102 which are connected to each other at opposite ends, the atomization assembly 200 is arranged in the housing 100 close to one end of the air outlet 102, and the power supply assembly 300 is arranged in the housing 100 close to one end of the air inlet 101; the atomization assembly 200 comprises an oil storage member 210 and an atomization core 220, the oil storage member 210 is provided with an oil storage chamber 210a for storing the atomization medium and an air passage 210b connected to the oil storage chamber 210a, the air passage 210b is connected to the air outlet 102, and at least part of the atomization core 220 is arranged at the oil storage chamber 210a and seals one end opening of the oil storage chamber 210a; the power supply assembly 300 comprises a bracket 310, a power supply 320 and a microphone 330, the bracket 310 is connected to the oil storage member 210, the bracket 310 has a power supply mounting position 3111 and a microphone mounting position 3121 therein, the microphone mounting position 3121 is connected to the air passage 210b, the power supply 320 is arranged in the power supply mounting position 3111 and connected to the atomization core 220, and the microphone 330 is arranged in the microphone mounting position 3121 and connected to the power supply 320.

[0050] Preferably, the end of the oil storage member 210 close to the bracket 310 and the end of the bracket 310 close to the oil storage member 210 jointly form an atomization cavity 11 which is connected to the air passage 210b and the power supply mounting position 3111, one side surface of the atomization core 220 is an atomization surface 222a, and the atomization surface 222a is arranged towards the atomization cavity 11.

[0051] When the user uses the electronic atomization device 10 to draw, because the air inlet 101 and the air outlet 102 are communicated, the external air enters the power installation position 3111 of the support 310 from the air inlet 101, and flows from the power installation position 3111 to the atomization cavity 11; at the same time, after the microphone 330 senses the negative pressure generated by the drawing, the power supply 320 drives the atomization core 220 to supply power, and the atomization medium flowing from the oil storage chamber 210a to the atomization core 220 is atomized on the atomization surface 222a by the atomization core 220 to generate aerosol, and the aerosol is mixed with the external air in the atomization cavity 11 and is drawn into the user's mouth through the air channel 210b from the air outlet 102.

[0052] It can be seen that through the above setting, the atomization assembly 200 and the power supply assembly 300 are both modular structures, and when assembling, as long as the atomization assembly 200 and the power supply assembly 300 are assembled respectively in advance, then the two are connected with each other, and finally the whole is assembled into the shell 100, the electronic atomization device 10 can be assembled, and therefore the installation steps can be simplified.

[0053] It can be understood that in some other embodiments, the electronic atomization device 10 can also not be provided with the shell 100, at this time the air inlet 101 is opened at the end of the support 310 away from the oil storage member 210, and the air outlet 102 is opened at the end of the oil storage member 210 away from the support 310, but the shell 100 can protect the atomization assembly 200 and the power supply assembly 300, and obviously it is the best embodiment.

[0054] The specific structures of the oil storage member 210, the atomization core 220 and the support 310 will be introduced below, and for the power supply 320, the power supply 320 includes a battery and a PCB board electrically connected to the battery, and the specific structure can refer to the prior art, which will not be described here.

[0055] In combination with FIGS. 1, 2 and 3, Figure 4 and Figure 5 In one embodiment, a partition 211 is arranged in the inner cavity of the oil storage member 210, the oil storage chamber 210a and the air channel 210b are separated by the partition 211, the size of the partition 211 in the first direction (i.e. the X direction in the figure) is smaller than the size of the outer wall of the oil storage member 210 in the first direction, so that the end of the oil storage member 210 connected with the support 310 is formed with a plug-in position 210c communicating the oil storage chamber and the air channel 210b, one end of the support 310 is inserted into the plug-in position 210c and covers the plug-in position 210c, one end of the oil storage chamber 210a close to the plug-in position 210c is provided with an opening, the atomization core 220 is arranged at the opening and covers the opening, and the end of the support 310 close to the oil storage member 210, the side wall of the plug-in position 210c and the atomization surface 222a jointly form the atomization cavity 11.

[0056] As an optional embodiment, the partition plate 211 has two pieces, and the two pieces of the partition plate 211 are arranged in a second direction (i.e. the Y direction in the figure) perpendicular to the first direction, so as to divide the inner cavity of the oil storage member 210 into an oil storage chamber 210a and two air passages 210b, and the two air passages 210b are arranged on two sides of the oil storage chamber 210a along the second direction.

[0057] It can be understood that the number of the partition plate 211 can also be one, which can be in a flat plate shape or a ring shape. The flat plate-shaped partition plate 211 divides the inner cavity of the oil storage member 210 into an oil storage chamber and an air passage 210b arranged adjacent to each other along the second direction, or the ring-shaped partition plate 211 divides the inner cavity of the oil storage member 210 into an air passage 210b surrounding the oil storage chamber, which is not limited herein.

[0058] Or in other embodiments, the oil storage member 210 can also be provided with an air pipe, and the outer wall of the air pipe and the inner wall of the oil storage member 210 jointly form the oil storage chamber 210a, the air passage 210b is arranged in the air pipe, and the atomizing core 220 is arranged in the air passage 210b, which is not limited herein.

[0059] Obviously, it can be seen that by arranging the structure of the atomizing assembly 200 as the structure of the embodiment shown in the figure, the air pipe can be avoided, so that the structure of the atomizing assembly 200 can be greatly simplified.

[0060] Referring to Figure 6 and Figure 7 , Figure 6 and Figure 7The structure of the atomizing core 220 of an embodiment is shown, in which the atomizing core 220 comprises an oil guide 221 and a heating element 222, the heating element 222 being wrapped on the outer wall of the oil guide 221 and electrically connected to the power supply 320. Preferably, the heating element 222 comprises a preheating part 2221 and a heating part 2222 connected to each other, in which the heating part 2222 is connected to the bottom wall of the oil guide 221, the bottom wall of the oil guide 221 facing away from the oil storage chamber 210a, the side of the heating part 2222 facing away from the oil guide 221 forms an atomizing surface 222a, and the preheating part 2221 is connected to the side wall of the oil guide 221, for example, attached to the outer surface of the side wall of the oil guide 221, or embedded in the side wall. In the embodiment shown in the figure, the number of preheating parts 2221 is two, and the two preheating parts 2221 are respectively connected to the opposite side walls of the oil guide 221. Of course, the number of preheating parts 2221 can also be one, two or four, and all the preheating parts 2221 are arranged in pairs, and the two preheating parts 2221 in each pair are arranged at intervals and respectively connected to the opposite side walls of the oil guide 221; and in the embodiment shown in the figure, the oil guide 221 is of a cubic structure, so as to match this structure, each preheating part 2221 is perpendicular to the heating part 2222. Of course, each preheating part 2221 can also be arranged at an arbitrary angle with the heating part 2222, depending on the structure of the oil guide 221, which is not limited here.

[0061] In their respective roles, the oil guide 221 is used to lock the atomizing medium entering the oil guide 221 from the oil storage chamber 210a, and to guide the atomizing medium in the oil storage chamber 210a to the atomizing surface 222a; the preheating part 2221 is used to generate heat at a lower temperature to preheat the atomizing medium in the oil guide 221, and also has the function of heat preservation for the atomizing medium in the oil guide 221, so that the temperature of the oil guide 221 is maintained within a certain temperature range, so as to better dissolve the atomizing medium in the oil guide 221, and better assist the flow of the atomizing medium to the atomizing surface 222a; and the heating part 2222 is used to generate heat at a higher temperature to heat the atomizing medium, so that it can be atomized to generate aerosol.

[0062] It can be understood that the heating temperature of the preheating part 2221 is lower than that of the heating part 2222. Preferably, the heating temperature of the preheating part 2221 is between 50-90 degrees Celsius, and the heating temperature of the heating part 2222 is between 160-220 degrees Celsius.

[0063] It can also be understood that the connection mode of the preheating part 2221 and the heating part 2222 can be in series with each other, can be in parallel with each other, and can be a combination of series and parallel, which is not limited here. The purpose of connecting the preheating part 2221 and the heating part 2222 in series and / or in parallel is to use the resistance value difference between the preheating part 2221 and the heating part 2222 to form different temperature zones at different parts of the heating element 222, so that different functions can be performed in layers or regions, so that the atomizing core 220 can have a better atomization effect.

[0064] Optionally, the material of the oil guide 221 is ceramic. The purpose of selecting ceramic is that ceramic can make the atomized aerosol particles smaller, the aerosol experience is more delicate, and the durability and service life are longer, which can better resist high temperature and chemical corrosion. Of course, the material of the oil guide 221 is not limited to ceramic, and can also be oil guide cotton and other materials, which are not limited here.

[0065] As shown in the structure of the preheating part 2221 and the heating part 2222, Figure 8 the preheating part 2221 includes a preheating wire 2221a and two oppositely arranged first electrodes 2221b, and the opposite ends of the preheating wire 2221a are respectively connected to one of the first electrodes 2221b; the heating part 2222 includes a heating wire 2222a and two oppositely arranged second electrodes 2222b, and the opposite ends of the heating wire 2222a are respectively connected to one of the second electrodes 2222b. Each first electrode 2221b is connected in series and / or parallel to a corresponding second electrode 2222b. Specifically, the preheating wire 2221a and / or the heating wire 2222a can be in a mesh shape, such as a circular, triangular or elliptical mesh shape, or can be in an S shape, a runway shape or other irregularly bent and extended structures, which can be made by various processes such as impact welding, etching, stamping or molding, which are not particularly limited here.

[0066] Optionally, in the embodiment shown in Figure 8 , the preheating wire 2221a is in a bent shape and includes a plurality of first preheating segments 2221c and second preheating segments 2221d connected between adjacent first preheating segments 2222c. The first preheating segment 2221c extends along the length direction of the preheating part 2221, and the second preheating segment 2221d extends along the width direction of the preheating part 2221. The first preheating segment 2221c is perpendicular to the second preheating segment 2221d. The length of the first preheating segment 2221c is less than the length of the second preheating segment 2221d. The opposite ends of each second preheating segment 2221d are respectively connected to two adjacent first preheating segments 2221c.

[0067] Optionally, the shape of the heating wire 2222a is also similar to that of the preheating wire 2221a, and is also in a meandering shape, including a plurality of first heating sections 2222c and second heating sections 2222d which are connected to adjacent first heating sections 2222c, respectively. The first heating sections 2222c extend along the length direction of the heating portion 2222, and the second heating sections 2222d extend along the width direction of the heating portion 2222. The first heating sections 2222c are perpendicular to the second heating sections 2222d. The length of the first heating sections 2222c is less than the length of the second heating sections 2222d. The opposite ends of each second heating section 2222d are connected to two adjacent first heating sections 2222c, respectively.

[0074] Further, in combination with Figure 6 and Figure 9As shown, in order to avoid the leakage of the atomized medium in the oil guide 221, the atomizing core 220 further comprises a sealing sleeve 223, which is sleeved on the oil guide 221, and the sealing sleeve 223 has an abutting portion 2231 surrounding the oil guide 221, one side of the abutting portion 2231 abutting the end of the partition plate 211 away from the air outlet 102, and the other side of the abutting portion 2231 abutting the bracket 310, so that the atomizing core 220 can be fixed in the oil storage part 210. Of course, the atomizing core 220 is not limited to the above-mentioned manner, but can also be fixed in the oil storage part 210 by other manners.

[0075] As shown in the structure of the bracket 310, in combination with Figure 4 and Figure 10 As shown, preferably, the bracket 310 is an integrally formed structure. Specifically, in the embodiment shown, Figure 10 the bracket 310 comprises a body 311 and a partition 312, the body 311 is a hollow frame structure and is connected to the end of the oil storage part 210 away from the air outlet 102, a power supply mounting position 3111 is formed in the body 311, and the partition 312 is arranged in the power supply mounting position 3111 and connected to the body 311, and a microphone mounting position 3121 is enclosed by the partition 312.

[0076] Optionally, as shown in Figure 9 and Figure 11 the end of the body 311 close to the oil storage part 210 has a flange 3112, the flange 3112 is attached to the side wall of the insertion position 210c and abuts against the side of the abutting portion 2231 of the sealing sleeve 223 of the atomizing core 220 away from the partition plate 211. In Figure 10 the implementation mode, the flange 3112 is annular, so that the flange 3112 encloses a groove 3113 used to form the atomizing chamber 11, the bottom wall of the groove 3113 is provided with a gas passing hole 3114 penetrating the bottom wall of the groove 3113, a microphone gas hole 3115 and a wire passing hole 3116, the power supply mounting position 3111 is connected through the gas passing hole 3114 and the wire passing hole 3116, the microphone mounting position 3121 is connected to the microphone gas hole 3115, and the wire passing hole 3116 is used for the lead of the atomizing core 220 to pass through, so that the heating element 222 of the atomizing core 220 is electrically connected to the power supply 320.

[0077] As can be understood, in other embodiments, in combination with Figures 9 to 11 the flange 3112 can also have at least two, and a gap 3117 is formed between the adjacent two flanges 3112, and the gap 3117 is connected to the air channel 210b and the atomizing chamber 11. In this way, the flange 3112 abuts against the atomizing core 220, and the gap 3117 can be used as a passage for the airflow to pass through, without the need to additionally increase the gas passing hole, thereby simplifying the processing process.

[0078] It should also be understood that the support 310 can also be an integrated structure formed by connecting multiple parts to each other, such as an integrated structure connected by fasteners or welded, which is not limited here.

[0079] In this way, by designing the support 310 as an integrated structure with the power supply mounting position 3111 and the microphone mounting position 3121 integrated, and by connecting one end of the support 310 to the end of the oil storage member 210 with the plug-in position 210c and abutting against the abutting portion 2231 of the atomizing core 220, the overall structure of the electronic atomizing device 10 can be simplified, and compared to the structure of most existing electronic atomizing devices 10 which are composed of multiple components, the electronic atomizing device 10 can eliminate multiple components such as an oil guide support, an atomizing core mounting seat, sealing silica gel, a power supply support, or a microphone mounting seat, and thus the installation steps of the electronic atomizing device 10 can be simplified, the electronic atomizing device 10 has better sealing performance, and the risk of product assembly failure and product oil leakage is greatly reduced.

[0080] It should be noted that after the user finishes smoking, aerosol inevitably remains in the atomizing cavity 11, and the aerosol will produce condensate after cooling. In order to avoid the condensate from dripping at the air passage hole 3114 or the microphone air hole 3115, causing the condensate to leak onto the power supply 320 or the microphone 330 and damaging the electronic atomizing device 10, as an improvement to the above-mentioned embodiments, please continue to refer to Figure 9 and Figure 11 The recess 3113 of the support 310 is provided with an oil blocking member 400, the oil blocking member 400 covers the air passage hole 3114 and the microphone air hole 3115, so that the oil blocking member 400 encloses an oil blocking cavity 12 in the recess 3113 which is separated from the atomizing cavity 11, the oil blocking cavity 12 is communicated with the atomizing cavity 11 through the air passage hole 401.

[0081] In this way, due to the blocking of the oil blocking member 400, the condensate in the atomizing cavity 11 can be prevented from dripping at the position of the air passage hole 3114 or the microphone air hole 3115. On the basis of the above-mentioned embodiments, the side of the oil blocking member 400 facing the atomizing cavity 11 is provided with an air column 402, and the air passage hole 401 penetrates the air column 402. Since the air column 402 has a certain height, after the condensate drips on the oil blocking member 400, the deposited condensate has a height lower than the height of the air column 402, and thus will not flow through the air passage hole 401 to the position of the air passage hole 3114 or the microphone air hole 3115.

[0082] More preferably, the side of the oil blocking member 400 facing the atomizing cavity 11 is also provided with an oil storage hole 403, the oil storage hole 403 is used to store the condensate formed in the atomizing cavity 11, and thus the condensate can be prevented from depositing on the surface of the oil blocking member 400 provided with the air column 402, and the possibility of the electronic atomizing device 10 being damaged by the condensate can be further reduced.

[0083] Each technical feature of the above-described embodiments can be combined with any other technical feature, and for the sake of brevity, not all possible combinations are described, but it is understood that the scope of the present disclosure encompasses all such possible combinations.

[0084] The above-described embodiments are merely illustrative of several embodiments of the present application, and the description is relatively specific and detailed, but should not be understood as limiting the scope of the patent application.
