Traditional electron cigarette's atomizing core can't ventilate when blockking up by the tobacco tar, and the inside miaow head of electron cigarette can't detect the air current change when the user smokes, then atomizing core can't work. And the atomizing subassembly of this application, the charge-in face of its base member can transmit atomizing medium to atomizing air flue in with atomizing medium contact after, the heat-generating body can provide the atomizing medium atomizing formation aerosol that can supply the suction in order to make atomizing air flue for the base member. In addition, the base body is also provided with a vent hole in a penetrating mode, and the vent hole is located on one side, far away from the feeding surface, of the atomizing air channel. Such an arrangement includes at least the following advantages:

firstly, the vent hole is additionally arranged outside the atomization air passage, even if the atomization medium of the atomization air passage is too much and is blocked by the atomization medium, the vent hole can keep a ventilation state, the change of the air flow can be detected, the atomization assembly can start to work when the change of the air flow is detected, the heating body generates heat, so that the atomization medium blocked and accumulated in the atomization air passage is atomized, and the atomization air passage is conducted again;

secondly, the vent hole is positioned on one side of the atomizing air passage far away from the feeding surface, so that the feeding surface can preferentially transmit the atomizing medium to the atomizing air passage, on one hand, sufficient atomizing medium can be supplied to the atomizing air passage, and the problems of dry burning and the like of the atomizing air passage due to insufficient supply of the atomizing medium are avoided;

thirdly, when the atomizing air passage is blocked by the atomizing medium and a user just starts to suck, the atomizing assembly just starts to work, the atomizing air passage may not be in a non-conducting state, and the atomizing air passage may not be capable of generating aerosol at the first time; however, since the vent hole has a certain amount of the atomization medium therein, the atomization medium in the vent hole can be atomized into a certain amount of aerosol in the first time to immediately supply the user with the suction, thereby ensuring better user experience;

fourth, compare in add means such as sensing air flue that is used for detecting the air current change outside the base member alone, the scheme of this application directly sets up the air vent on the base member, and technology and structure are more simple on the one hand, can reduce and make the degree of difficulty and manufacturing cost, and on the other hand need not to add other extra parts, and this is the inner space of having practiced thrift the product undoubtedly, is favorable to realizing the essence simplification, the small and exquisite of product, more receives user favor.

Such setting can be thought that the feeding face is whole more close to atomizing air flue, and the feeding face can be supplied atomizing medium to atomizing air flue in preferentially, and then the tobacco tar supply volume that the air vent can be received is less than atomizing air flue, can avoid the air vent as far as possible because of atomizing medium supply volume is too high and is blockked up.

The reason why it is emphasized that the one atomizing air passage closest to the second reference point is needed is that the other atomizing air passages may be located further away from the second reference point, even if the distance from the second reference point to the first reference point of the vent hole is greater, but the second reference point of the feed face will preferentially deliver the atomizing medium to the one atomizing air passage closest thereto, and the second reference point of the feed face will contribute little to the delivery of the atomizing medium to the other atomizing air passages. The reason why it is emphasized that the third reference point is the point closest to the inner circumferential surface of the nebulization channel which is the farthest away from the second reference point is that the nebulization medium of the second reference point of the feed surface is transported to the third reference point which is the farthest away from the nebulization channel and needs to be passed around the circumference of the nebulization channel, so that the actual transport distance of the nebulization medium is greater than the straight distance between the second reference point and the third reference point.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Referring to fig. 1 and 2, the present application provides an atomizing assembly 11, which includes a substrate 100 and a heating element 200. The heat-generating body 200 is at least partially in contact with the base body 100. Specifically, the base 100 is substantially cylindrical, and may be in the shape of a cylinder, a cube, etc., and the shape of the base 100 is described herein for clarity of the disclosure and is not intended to limit the shape of the base 100. More specifically, the base 100 has the atomizing air passage 110 and the vent hole 120 that are independent from each other, and the atomizing air passage 110 and the vent hole 120 that are not connected to each other may be considered as being penetrated through in the axial direction. The outer circumferential surface of a portion of the base 100 is a feeding surface 130, the vent holes 120 are located on a side of the atomizing air duct 110 away from the feeding surface 130, and the base 100 contacts the atomizing medium through the feeding surface 130 and transfers the atomizing medium to the atomizing air duct 110 and the vent holes 120.

The atomizing medium may be a material capable of transferring and providing volatile components, such as smoke, through the substrate 100. The substrate 100 may be made of a porous material with a certain porosity, such as ceramic or glass, etc., that is, the substrate 100 exhibits a "porous" morphology at a microscopic level, and transports the atomizing medium inside the substrate 100 by capillary action, etc., and transports the atomizing medium to the inner wall of the atomizing air channel 110 to atomize and form the aerosol. In actual operation, the atomizing medium such as tobacco tar can be transferred to the inner wall of the atomizing air duct 110 through the feeding surface 130 of the substrate 100, and flows out to form a plurality of droplets under the influence of time and gravity, and the droplets are continuously collected and do not drop under the action of surface tension, so that the atomizing air duct 110 may be blocked. In addition, the porosity of the porous material of which the base 100 is made may range from 20% to 80%, and preferably, the porosity of the porous material may range from 40% to 80%. The porosity of the porous material can be adjusted according to the components of the tobacco juice, for example, when the viscosity of the atomization medium such as tobacco tar is high, the porous material with high porosity can be selected to be made into the substrate 100, so as to ensure the liquid guiding effect.

Traditional electron cigarette's atomizing core can't ventilate when blockking up by the tobacco tar, then the inside miaow head of electron cigarette can't detect the air current change when the user smokes, then atomizing core can't work. In the atomizing assembly 11 of the present application, the feeding surface 130 of the base 100 contacts with the atomizing medium, and then transfers the atomizing medium into the atomizing air passage 110, and the heating element 200 can provide heat for the base 100 to atomize the atomizing medium in the atomizing air passage 110 to form aerosol for suction. In addition, the base 100 further has a vent hole 120 formed therethrough, and the vent hole 120 is located on a side of the atomizing air duct 110 away from the feeding surface 130. Such an arrangement includes at least the following advantages:

firstly, the vent hole 120 is additionally arranged outside the atomizing air passage 110, even if the atomizing medium in the atomizing air passage 110 is too much and is blocked by the atomizing medium, the vent hole 120 can keep a ventilation state, so that the change of the air flow can be detected, the atomizing assembly 11 can start to work when the change of the air flow is detected, the heating body 200 generates heat to further promote the atomizing medium blocked and accumulated in the atomizing air passage 110 to atomize, and the atomizing air passage 110 is conducted again;

secondly, the vent holes 120 are located on one side of the atomizing air passage 110 far away from the feeding surface 130, so that the feeding surface 130 can preferentially transmit the atomizing medium to the atomizing air passage 110, on one hand, sufficient atomizing medium can be supplied to the atomizing air passage 110, and the problem that the atomizing air passage 110 is dry-burned due to insufficient supply of the atomizing medium is avoided, on the other hand, the vent holes 120 are far away from the feeding surface 130, the atomizing medium is preferentially supplied to the atomizing air passage 110, and the atomizing medium transmitted to the vent holes 120 is less, so that the vent holes 120 can be prevented from being blocked by the atomizing medium, and the conduction of the vent holes 120 is ensured;

thirdly, when the nebulizing air channel 110 is blocked by the nebulizing medium, the nebulizing assembly 11 starts to work when the user starts to suck, the nebulizing air channel 110 may not be in the on state, and the nebulizing air channel 110 may not be able to generate aerosol for the first time. However, since the vent 120 has a certain amount of the aerosol medium therein, the aerosol medium in the vent 120 can be atomized to form a certain amount of aerosol in the first time period to immediately supply the user with the smoking, thereby ensuring better user experience;

fourth, compare in means such as the sensing air flue that is used for detecting the air current change in addding alone outside base member 100, the scheme of this application directly sets up air vent 120 on base member 100, and technology and structure are more simple on the one hand, can reduce and make the degree of difficulty and manufacturing cost, and on the other hand need not to add other extra parts, and this is the inner space of having practiced thrift the product undoubtedly, is favorable to realizing the essence simplification, the small and exquisite of product, more receives user's favor.

Specifically, as shown in fig. 3, in some embodiments, in the cross-section of the base 100, any point on the inner circumferential surface of the vent hole 120 is taken as a first reference point a, and any point on the feeding surface 130 is taken as a second reference point B. The distance between the first reference point a and the second reference point B is a first distance L1. The maximum distance between the second reference point B and the inner peripheral surface of the closest atomizing air duct 110 is a second distance L2, and the first distance L1 is greater than or equal to the second distance L2.

For example, as shown in fig. 3, in some embodiments, the atomizing air passage 110 and the vent hole 120 are both provided as one, and a point on the inner peripheral surface of the atomizing air passage 110 that is farthest from the second reference point B is a third reference point C, and a distance between the third reference point C and the second reference point B is a second distance L2.

As another example, as shown in fig. 4, in other embodiments, the number of the atomizing air passages 110 may be multiple, that is, as shown in fig. 2, at least two atomizing air passages 110, and on the inner peripheral surface of one atomizing air passage 110 closest to the second reference point B, there is a third reference point C farthest from the second reference point B, that is, a point on the inner peripheral surface of one atomizing air passage 110 closest to the second reference point B, which is farthest from the second reference point B, and the distance between the third reference point C and the second reference point B is the second distance L2. Such an arrangement may be considered that the feeding surface 130 is closer to the atomizing air duct 110 as a whole, the feeding surface 130 preferentially supplies the atomizing medium into the atomizing air duct 110, the supply amount of the smoke that can be received by the ventilation hole 120 is smaller than that of the atomizing air duct 110, and the blockage of the ventilation hole 120 due to the excessively high supply amount of the atomizing medium can be avoided as much as possible.

The reason why it is emphasized that the one atomizing air passage 110 closest to the second reference point B is needed is that the other atomizing air passages 110 may be further away from the second reference point B, even if the distance from the second reference point B to the first reference point a of the vent hole 120 is larger, but the second reference point B of the feed surface 130 will preferentially transfer the atomizing medium to the one atomizing air passage 110 closest thereto, and the second reference point B of the feed surface 130 will contribute little to the delivery of the atomizing medium by the other atomizing air passages 110. For example, as shown in fig. 4, the two atomizing air passages 110 are provided, and include a first atomizing air passage 111 and a second atomizing air passage 112 which are spaced from each other, the second atomizing air passage 112 is farther from the second reference point B of the feeding surface 130, and the second atomizing air passage 112 is approximately separated from the second reference point B by the first atomizing air passage 111, so that it can be seen that the second reference point B of the feeding surface 130 has a small contribution to the delivery of the atomizing medium of the second atomizing air passage 112.

The reason why it is emphasized that the third reference point C needs to be the point where the inner peripheral surface of the closest atomizing channel is farthest from the second reference point B is that the atomizing medium delivered from the second reference point B of the feed surface 130 to the third reference point C, which is farthest from the atomizing air passage 110, needs to be bypassed around the periphery of the atomizing air passage 110, so that the actual delivery distance of the atomizing medium is greater than the straight-line distance between the second reference point B and the third reference point C. For example, as shown in fig. 3 and 4, the nebulizing medium at second reference point B of feed surface 130 may need to be delivered to third reference point C, i.e., the side of nebulizing airway 110 facing away from second reference point B, and may need to be delivered from both sides of nebulizing airway 110 along the circumference.

More specifically, as shown in fig. 3 and 4, in some embodiments, the cross-sectional profile of the nebulizing airway 110 is circular, and a line connecting the second reference point B and the third reference point C passes through the center of the circular cross-section of the nebulizing airway 110. In other embodiments, the cross-sectional profile of the atomizing air passage 110 may also be rectangular, triangular, diamond-shaped, regular or irregular polygonal, etc., in other words, the cross-sectional profile of the atomizing air passage 110 is not limited in the present application. Similarly, the shape of the cross-sectional profile of the vent 120 in each embodiment is not limited in this application, and is not described herein.

More specifically, as shown in fig. 5, in some embodiments, the vent holes 120 may be provided in plurality, and any point on the inner circumferential surface of one vent hole 120 closest to the feeding surface 130 is the first reference point a.

More specifically, as shown in fig. 5, in some embodiments, the feeding surface 130 is provided in a plurality, the feeding surfaces 130 are distributed at intervals along the circumferential direction of the base 100 on the outer circumferential surface of the base 100, and any point on any one feeding surface 130 is the second reference point B. For example, as shown in fig. 5, in some embodiments, the atomizing air passage 110 is provided in a plurality, and the atomizing air passage 110 corresponds to the feeding surface 130 in number and position. For another example, in other embodiments, only one atomizing channel may be provided, and a plurality of feeding surfaces 130 may be provided, the plurality of feeding surfaces 130 are distributed at intervals on the outer circumferential surface of the base body 100 along the circumferential direction of the base body 100, and the plurality of feeding surfaces 130 correspond to one atomizing channel at the same time.

More specifically, in some of these embodiments, the cross-sectional area of the vent 120 is less than or equal to the cross-sectional area of the nebulizing airway 110. For example, as shown in fig. 1-6, the cross-sectional area of the vent holes 120 is less than the cross-sectional area of the nebulizing airway 110.

More specifically, as shown in fig. 6 and 7, in some embodiments, the atomizing assembly 11 further includes an atomizing sleeve 300, the atomizing sleeve 300 is sleeved on the outer peripheral surface of the base 100, a feed inlet 310 is formed through the side peripheral surface of the atomizing sleeve 300, and the feed surface 130 is at least partially exposed through the feed inlet 310 to contact with the atomizing medium. For example, in some embodiments, the feeding surface 130 may refer to only a portion of the outer periphery of the substrate 100 itself as the feeding surface, which can absorb the aerosol medium such as smoke, and the remaining outer periphery may be a non-porous material or a low-porous material, which does not absorb the aerosol medium. For another example, as shown in fig. 7 and 9, in other embodiments, the substrate 100 may be made of a porous material as a whole, and the entire outer circumferential surface may absorb the atomizing medium such as tobacco tar, and then only the portion of the outer circumferential surface of the substrate 100 exposed at the feeding hole 310 may be considered as the feeding surface 130.

The vent holes 120 of the present application can be formed in a variety of ways, for example, as shown in fig. 1, 2, 3, 4, 5, and 6, in some embodiments, the vent holes 120 are individually surrounded by the substrate 100.

For another example, as shown in fig. 8 and fig. 9, in other embodiments, the atomizing assembly 11 further includes an atomizing sleeve 300, the atomizing sleeve 300 is sleeved on an outer circumferential surface of the base 100, a groove is formed on the outer circumferential surface of the base 100, the groove penetrates through the base 100 along an axial direction of the base 100, and an inner wall of the atomizing sleeve 300 and a groove wall of the groove enclose to form the vent 120. Because the inner peripheral surface of the vent hole 120 is the pipe wall of the atomizing sleeve 300, and the joint of the pipe wall and the groove wall of the groove objectively has a small gap, the blockage of the vent hole 120 caused by the gathering of atomizing media such as tobacco tar and the like at a certain position due to the action of surface tension can be effectively prevented.

Referring to fig. 2, in some embodiments, the heat emitted from the heat generating unit 200 can be radiated into the atomizing air duct 110 from the inner circumferential surface of the atomizing air duct 110. This may be considered as the heat generating body 200 being provided only in the atomizing air passage 110, or only in the vicinity of the atomizing air passage 110; the heating element 200 is not disposed in any other air passages except the atomizing air passage 110, such as the vent hole 120. It can be considered that only the atomizing air duct 110 is provided with the heating element 200, and the air vent 120 is not provided with a heat source, the atomizing medium in the atomizing air duct 110 can be rapidly atomized under the heating of the heating element 200, the content of the atomizing medium in the substrate 100 near the atomizing air duct 110 may be reduced, and the atomizing medium in the substrate 100 is preferentially supplied to the atomizing air duct 110. The heating element 200 may be at least one of a spiral heating wire, a metal heating sheet, a metal heating net, and a resistance paste film.

Specifically, in some embodiments, the heat generating body 200 is embedded in the inner circumferential surface of the atomizing air duct 110, i.e., the heat generating body 200 is partially located below the inner circumferential surface of the atomizing air duct 110, and partially located above the inner circumferential surface of the atomizing air duct 110, i.e., partially exposed in the atomizing air duct 110.

Specifically, in other embodiments, the heat generating body 200 is embedded under the inner peripheral surface of the atomizing air duct 110, i.e., the heat generating body 200 is not exposed in the atomizing air duct 110.

Specifically, in other embodiments, the heat generating body 200 is laid on the inner peripheral surface of the atomizing air duct 110, that is, the heat generating body 200 is only disposed on the surface of the inner peripheral surface, and is not embedded in the inner peripheral surface of the atomizing air duct 110.

More specifically, for example, as shown in fig. 2, in some embodiments, the heat-generating body 200 covers the entire inner circumferential surface of the atomizing air duct 110. For another example, in other embodiments, the heating element 200 may be distributed on the inner peripheral surface of the atomizing air channel 110 at a certain interval, or the heating element 200 may be hollow.

More specifically, in some embodiments, when a plurality of atomizing air passages 110 are provided, a plurality of heating elements 200 may be provided, and correspond to the atomizing air passages 110 one by one.

In addition, as shown in fig. 10, the present application is also directed to an atomizing device 10, which includes a main body 12, a storage chamber (not shown), and an atomizing assembly 11 according to any of the embodiments described above.

One end of the atomizing air passage 110 is communicated with the air inlet 121, the other end of the atomizing air passage 110 is communicated with the air outlet 122, one end of the vent hole 120 is communicated with the air inlet 121, the other end of the vent hole 120 is communicated with the air outlet 122, and the sensing element 13 is used for detecting the airflow change of the atomizing air passage 110 and/or the vent hole 120. The sensor element 13 may be a microphone or the like. The sensing element 13 can detect the airflow change in the airflow path between the air inlet 121 and the air outlet 122, for example, at least one of the nebulizing air channel 110 and the air vent 120 is in a conducting state, when the user sucks from the air outlet 122, and the side of the sensing element 13 close to the air outlet 122 detects the negative pressure, the sensing element 13 can send a signal to start the operation of the nebulizing device 10.

More specifically, as shown in fig. 10, in some embodiments, the sensing element 13 may be disposed between the air outlet 122 and the atomizing assembly 11. In other embodiments, the sensing element 13 may also be disposed between the air inlet 121 and the atomizing assembly 11. As long as the atomizing assembly 11 is not blocked, that is, at least one of the atomizing air channel 110 and the vent 120 is in a conducting state, the sensing element 13 can work normally, and then the heating element 200 of the atomizing assembly 11 is driven to work.

The atomizing device 10 and the aerosol generating apparatus may have the atomizing element 11 of the above embodiments, and therefore, the following advantages are also included:

firstly, the vent hole 120 is additionally arranged outside the atomizing air passage 110, even if the atomizing medium in the atomizing air passage 110 is too much and is blocked by the atomizing medium, the vent hole 120 can keep a ventilation state, so that the change of the air flow can be detected, the atomizing assembly 11 can start to work when the change of the air flow is detected, the heating body 200 generates heat to further promote the atomizing medium blocked and accumulated in the atomizing air passage 110 to atomize, and the atomizing air passage 110 is conducted again;

secondly, the vent holes 120 are located on one side of the atomizing air passage 110 far away from the feeding surface 130, so that the feeding surface 130 can preferentially transmit the atomizing medium to the atomizing air passage 110, on one hand, sufficient atomizing medium can be supplied to the atomizing air passage 110, and the problem that the atomizing air passage 110 is dry-burned due to insufficient supply of the atomizing medium is avoided, on the other hand, the vent holes 120 are far away from the feeding surface 130, the atomizing medium is preferentially supplied to the atomizing air passage 110, the amount of the atomizing medium transmitted to the vent holes 120 is small, the vent holes 120 can be prevented from being blocked by the atomizing medium, and the conduction of the vent holes 120 is ensured;

thirdly, when the nebulizing air channel 110 is blocked by the nebulizing medium, the nebulizing assembly 11 starts to work when the user starts to suck, the nebulizing air channel 110 may not be in the on state, and the nebulizing air channel 110 may not be able to generate aerosol for the first time. However, since the vent 120 has a certain amount of the aerosol medium therein, the aerosol medium in the vent 120 can be atomized to form a certain amount of aerosol in the first time period to immediately supply the user with the smoking, thereby ensuring better user experience;

fourth, compare in add means such as the sensing air flue that is used for detecting the air current change alone outside base member 100, the scheme of this application directly sets up air vent 120 on base member 100, and technology and structure are more simple on the one hand, can reduce the manufacturing difficulty and manufacturing cost, and on the other hand need not to add other extra parts, and this is the inner space of having practiced thrift the product undoubtedly, is favorable to realizing the essence of product and simplifies, the smallclothes, more receives user favor.
