However, due to its high viscosity and low fluidity, it is difficult to ventilate the e-liquid in the oil tank, especially when the e-liquid in the oil tank gradually decreases, the negative pressure in the oil tank increases, which makes it difficult for the e-liquid in the oil tank to flow and the oil supply is slow.

[0038] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0039] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0040] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0041] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0042] Due to its high viscosity, high-viscosity e-liquid has low fluidity, which makes it difficult to ventilate the e-liquid in the oil tank. In particular, when the e-liquid in the oil tank gradually decreases, the negative pressure in the oil tank increases, which makes it difficult for the e-liquid in the oil tank to flow and the oil supply is slow. At present, the industry often uses the method of adding additional power to preheat the e-liquid, thereby increasing the fluidity of the e-liquid (high-viscosity e-liquid has the characteristic that the viscosity decreases with increasing temperature) to improve the difficulty in ventilating the e-liquid. However, the above solution will bring additional battery energy loss and a complex circuit structure, resulting in a large aerosol generating device that is not easy to carry and has high cost.

[0043] Based on this problem, the inventor of the present application invented an aerosol generating device and specially designed the structure of the atomizing assembly, by placing at least part of the airway wall of the ventilation channel in the atomizing bin to increase the temperature of the e-liquid in and near the ventilation channel, thereby increasing the fluidity of the e-liquid in the tank. This does not require additional battery energy loss and does not complicate the circuit structure.

[0044] See also Figure 1 and Figure 2The embodiment of the present application provides an aerosol generating device, including a battery assembly 2000, an atomizer assembly 1000 and a nozzle 3000; the battery assembly 2000 is electrically connected to the atomizer assembly 1000, and the battery assembly 2000 is used to supply power to the atomizer assembly 1000 so that the atomizer assembly 1000 starts atomization; the atomizer assembly 1000 is used to atomize the tobacco oil into aerosol particles; the nozzle 3000 is connected to the atomizer assembly 1000 and is used to deliver the aerosol particles generated by the atomizer assembly 1000 to the oral cavity of the smoker.

[0045] See also Figures 3 to 6 In one embodiment, the atomizer assembly 1000 includes a shell assembly 100 and a heating element 200. The shell assembly 100 is formed with an oil tank 140 and an atomizer tank 150. The heating element 200 is arranged in the shell assembly 100 and connects the atomizer tank 150 and the oil tank 140. The heating element 200 includes an atomizer surface 220 connected to the atomizer tank 150. A ventilation channel 160 is also formed in the shell assembly 100. The shell assembly 100 includes an airway wall 165 forming the ventilation channel 160, and the airway wall 165 is at least partially located in the atomizer tank 150.

[0046] The atomizer assembly 1000 provided in the embodiment of the present application is provided by connecting the atomizer surface 220 of the heating element 200 to the atomizer bin 150, so that the atomizer surface 220 can generate high-temperature aerosol, so that the temperature in the atomizer bin 150 is high, and at the same time, the airway wall 165 of the ventilation channel 160 is at least partially located in the atomizer bin 150, so that the temperature in the atomizer bin 150 can be transferred to the high-viscosity oil in and near the ventilation channel 160 through the airway wall 165, thereby increasing the fluidity of the smoke oil, so that the smoke oil can be ventilated smoothly. At the same time, the present application does not need to increase additional power, reduce energy consumption and cost, and does not need to increase the circuit structure, simplify the structure of the atomizer assembly, reduce the volume of the atomizer assembly 1000, and is easy to carry.

[0047] In addition, the gas entering the oil bin 140 from the ventilation channel 160 will not immediately rise to the empty position of the oil bin 140 due to the influence of the viscosity of the smoke oil, but will rise slowly, thereby pressurizing the smoke oil and squeezing the smoke oil as much as possible toward the oil inlet end of the heating element 200 to improve the utilization rate of the smoke oil.

[0048] In one embodiment, see Figure 6The ventilation channel 160 has an air inlet end 161 and an air outlet end 162 that are relatively arranged. The air inlet end 161 of the ventilation channel 160 is connected to the atomization bin 150, and the air outlet end 162 of the ventilation channel 160 is connected to the oil bin 140. One end of the atomization bin 150 is connected to the suction nozzle 3000, and the other end of the atomization bin 150 is connected to the outside. The other end of the atomization bin 150 can be directly connected to the outside, or a channel can be formed in the battery assembly 2000, and the atomization bin 150 can be connected to the outside through the channel. It can be understood that in other embodiments of the present application, the air inlet end 161 of the ventilation channel 160 can also be directly connected to the external atmosphere, which is not the only limitation here.

[0049] The heating element 200 connects the atomization bin 150 and the oil bin 140. The heating element 200 may be disposed in the oil bin 140 and connected to the atomization bin 150; or the heating element 200 may be installed between the atomization bin 150 and the oil bin 140; or the heating element 200 may be disposed in the atomization bin 150 and connected to the oil bin 140.

[0050] See also Figure 6 , the black arrows in the figure represent the flow direction of the fluid, wherein the arrow in the middle flowing from bottom to top represents the gas flow in the airflow channel of the atomizer assembly 1000, the arrow on the left represents the smoke oil in the oil tank 140 flowing downward and rightward to the heating element 200, and the arrow on the right represents the gas in the atomizer bin 150 flowing from bottom to top to the oil tank 140 through the ventilation channel 160. Specifically, when the smoker draws on the suction nozzle 3000, the external gas enters the atomizer bin 150 from bottom to top, and also affected by the airflow, the smoke oil in the oil tank 140 enters the heating element 200 from the oil inlet surface 210 of the heating element 200, and the aerosol particles heated and atomized by the heating element 200 are introduced into the atomizer bin 150 through the atomization surface 220, and then enter the suction nozzle 3000 from the atomizer bin 150 under the influence of the airflow, and then enter the mouth of the smoker through the suction nozzle 3000. When the e-liquid is consumed, the negative pressure of the oil tank 140 will increase. In order to maintain the balance of internal and external air pressures, the outside air will enter the oil tank 140 through the ventilation channel 160. At the same time, the gas in the atomization tank 150 or the outside air will also enter the oil tank 140 through the ventilation channel 160, thereby increasing the fluidity of the e-liquid in the oil tank 140 and ensuring smooth ventilation.

[0051] In one embodiment, see Figure 6 The heating element 200 is longitudinally arranged between the atomization bin 150 and the oil bin 140 , and the heating element 200 has an oil inlet surface 210 facing the oil bin 140 and an atomization surface 220 facing the atomization bin 150 .

[0052] The longitudinal direction here refers to the direction extending roughly along the axial direction of the entire atomizer assembly 1000. For example, the heating element 200 is arranged in a direction parallel to the axial direction of the atomizer assembly 1000, or the heating element 200 is arranged in a manner of forming an inclined angle with the axial direction of the atomizer assembly 1000. Generally speaking, the extension trend of the heating element 200 is the same as the axial direction of the atomizer assembly 1000, that is, the heating element 200 is installed on the side of the atomizer bin 150, and the oil inlet surface 210 and the atomizing surface 220 of the heating element 200 are arranged roughly parallel to the airflow direction in the atomizer bin 150. In fact, when designing, the block heating element 200 generally designs the thickness between the oil inlet surface 210 and the atomizing surface 220 to be smaller, and the area of ​​the oil inlet surface 210 of the heating element 200 to be larger. Therefore, the design of installing the heating element 200 on the side of the atomizer bin 150 in this application can reduce the lateral space occupied by the heating element 200. It can be understood that in other embodiments of the present application, when the structural volume of the atomization assembly 1000 allows, the heating element 200 can also be horizontally arranged in the atomization chamber 150, which is not the only limitation here.

[0053] In one embodiment, see Figure 6 , the airway wall 165 of the ventilation channel 160 is arranged horizontally opposite to the atomization surface 220 of the heating element 200, that is, the airway wall 165 of the ventilation channel 160 is a wall surface arranged opposite to the atomization surface 220 of the heating element 200, and the aerosol particles atomized by the heating element 200 will hit the wall surface on the opposite side of the heating element 200, so that the airway wall 165 can be quickly heated up, and then the smoke oil in and near the ventilation channel 160 can be quickly heated. Moreover, after testing, when the airway wall 165 of the ventilation channel 160 is a wall surface arranged opposite to the atomization surface 220 of the heating element 200, the temperature in the ventilation channel 160 is relatively higher. It can be understood that in other embodiments of the present application, the airway wall 165 of the ventilation channel 160 can also be arranged horizontally and obliquely opposite to the atomizing surface 220 of the heating element 200, that is, the airway wall 165 of the ventilation channel 160 is a wall surface arranged obliquely opposite to the atomizing surface 220 of the heating element 200, which can also make the ventilation channel 160 heat up quickly.

[0054] In another embodiment of the present application, see Figures 7 to 9 The ventilation channel 160 is at least formed by the heating element 200 and the housing assembly 100 , that is, the heating element 200 is set as part of the side wall of the ventilation channel 160 . Figure 7In the figure, the heating element 200 is not shown because it will block the ventilation channel 160. The bold arrow in the middle represents the mainstream direction of the gas, and the bold arrow on the right represents the gas entering the ventilation channel 160 through the atomization chamber 150. Specifically, the shell assembly 100 and the heating element 200 together enclose the ventilation channel 160, so that the airway wall 165 of the shell assembly 100 for enclosing the ventilation channel 160 is arranged close to the heating element 200, and the temperature rises quickly. In addition, the temperature of the heating element 200 itself is relatively high, so that the heat can be quickly directed into the ventilation channel 160 to promote the fluidity of the smoke oil in the oil tank 140. In addition, the heating element 200 can be used to preheat the smoke oil in the ventilation channel 160, and on the other hand, it can absorb excess smoke oil to ensure the smoothness of the ventilation channel 160. In other embodiments of the present application, the airway wall 165 of the ventilation channel 160 can also be arranged close to the atomization surface 220 of the heating element 200, so that the aerosol generated from the atomization surface 220 can quickly heat the airway wall 165, thereby transferring heat to the tobacco oil in and near the ventilation channel 160.

[0055] In one embodiment, at least two ventilation channels 160 are formed on the housing assembly 100, and each ventilation channel 160 is arranged in sequence at intervals. In this embodiment, by setting a plurality of ventilation channels 160, when one ventilation channel 160 is blocked, another ventilation channel 160 can be ventilated smoothly, and they are alternated with each other, thereby avoiding the dry burning and scorching of the heating element 200 due to poor ventilation when a single ventilation channel 160 is blocked due to the cumulative effect.

[0056] In one embodiment, two ventilation channels 160 are formed on the housing assembly 100. Figure 6 , the airway wall 165 of one of the ventilation channels 160 is arranged opposite to the atomizing surface 220 of the heating element 200; please refer to Fig. 9 , another ventilation channel 160 is formed by at least the shell assembly 100 and the heating element 200. It has been verified by experiments that the combination of the above ventilation channels 160 can significantly improve the ventilation effect of the smoke oil. It can be understood that in other embodiments of the present application, the number of ventilation channels 160 can also be one, three or more than three, and the airway wall 165 of the ventilation channel 160 can also be arranged horizontally and obliquely to the heating element 200, or be arranged close to the heating element 200, which is not the only limitation here.

[0057] In one embodiment, see Fig.10The ventilation channel 160 includes a main channel 163 and at least two sub-channels 164, each of which is spaced apart along the length extension direction of the main channel 163, and each of which has an air inlet end 161, and the sub-channel 164 extends from the air inlet end 161 to the main channel 163. In this embodiment, by setting the ventilation channel 160 as a tree-level channel, when the smoke oil is consumed and ventilation begins, the gas can enter the main channel 163 from the two sub-channels 164 at the same time, or enter the main channel 163 from any of the sub-channels 164, and then enter the oil tank 140 through the main channel 163 to achieve ventilation, which can effectively improve the ventilation efficiency and reduce the blockage caused by the accumulation of high-viscosity smoke oil.

[0058] In one embodiment, see Fig.10 , the ventilation channel 160 includes two sub-channels 164. It can be understood that in other embodiments of the present application, the ventilation channel 160 may also include one, three or four sub-channels 164, which is not limited here.

[0059] In one embodiment, see Fig.10 , the main channel 163 extends along the axial direction of the housing assembly 100, and the branch channel 164 is arranged toward the heating element 200, so that the gas can flow from the branch channel 164 to the main channel 163 under the influence of the airflow when the smoker sucks the suction nozzle 3000, and then flow from the main channel 163 to the oil tank 140. It can be understood that in other embodiments of the present application, the main channel 163 may not be arranged parallel to the axial direction of the housing assembly 100, but may be arranged relatively inclined, but the extension trend of the main channel 163 remains unchanged, so that the gas in the main channel 163 can flow under the influence of the airflow.

[0060] In one embodiment, see Figure 6 The atomizer assembly 1000 further includes a seal 300, through which the heating element 200 is sealed and installed between the oil bin 140 and the atomizer bin 150. The setting of the seal 300 makes the connection between the heating element 200 and the housing assembly 100 sealed, so that the tobacco oil in the oil bin 140 will not flow from the gap between the heating element 200 and the housing assembly 100 to the atomizer bin 150, thereby reducing the risk of the tobacco oil that has not been atomized being directly inhaled into the mouth of the smoker.

[0061] In one embodiment, see Figure 6 and Fig.11The housing assembly 100 includes a mounting seat 110, a smoke bomb tube 120 and an oil pipe 130; the smoke bomb tube 120 includes an atomizing section 121 and a smoke guiding section 122 which are connected to each other, the diameter of the atomizing section 121 is larger than the diameter of the smoke guiding section 122, and the atomizing section 121 and the smoke guiding section 122 are connected by a step plate 123; the atomizing section 121 is sleeved outside the mounting seat 110; the oil pipe 130 is sleeved outside the atomizing section 121 and the smoke guiding section 122, and the oil pipe 130 and the smoke guiding section 122 are connected to each other. The sections 122 are separated to form an oil bin 140; the heating element 200 is installed in the atomizing section 121 to divide the inner cavity of the atomizing section 121 into an atomizing bin 150 and a buffer bin 170, the atomizing bin 150 is connected with the smoke guiding section 122, specifically, the atomizing bin 150 is connected with the smoke guiding channel 1221 of the smoke guiding section 122, and a through opening 1231 is formed on the step plate 123, and the oil in the oil bin 140 flows to the buffer bin 170 through the through opening 1231 for atomization of the heating element 200. In this embodiment, by dividing the cigarette bomb tube 120 into an atomizing section 121 for atomization and a smoke guiding section 122 for guiding smoke, and setting the diameter of the atomizing section 121 to be relatively larger than the diameter of the smoke guiding section 122, there is enough space to install the heating element 200; at the same time, by forming an oil tank 140 between the oil pipe 130 and the smoke guiding section 122, and the oil pipe 130 can be sleeved outside the atomizing section 121, the diameter of the atomizing section 121 is increased without increasing the outer diameter of the entire housing assembly 100, that is, the side installation of the heating element 200 is achieved without increasing the overall outer diameter of the atomizing assembly 1000, which is conducive to miniaturization, and at the same time, the opposite sides of the heating element 200 can be connected to the atomizing bin 150 and the oil bin 140 respectively. In addition, in the present application, the buffer bin 170 is actually a part of the oil bin 140.

[0062] In one embodiment, see Figure 6 and Fig.12 The mounting seat 110 has a support plate 111 arranged opposite to the step plate 123, and the heating element 200 is supported on the support plate 111 and arranged in the inner cavity of the atomizing section 121. In this embodiment, the heating element 200 is supported by the support plate 111, that is, the support plate 111 and the atomizing section 121 are jointly enclosed to form an installation space for installing the heating element 200, thereby avoiding the formation of a mounting hole for installing the heating element 200 on the side wall of the atomizing section 121, thereby simplifying the structural design of the atomizing section 121. At the same time, the mounting seat 110 has a stronger supporting capacity relative to the atomizing section 121, so that the installation stability of the heating element 200 is better.

[0063] In one embodiment, see Fig.12The mounting seat 110 further includes a surrounding plate 112 formed on a peripheral edge of the supporting plate 111, an extension plate 113 axially extends from the top of the surrounding plate 112, and the extension plate 113 is in an arc shape. The atomizing section 121 is sleeved outside the extension plate 113, and the inner side wall of the atomizing section 121 is sleeved with the outer side wall of the extension plate 113 by interference fit, and the bottom end of the atomizing section 121 is supported on the surrounding plate 112. The oil pipe 130 is sleeved outside the atomizing section 121, and the bottom end of the oil pipe 130 is supported on the surrounding plate 112.

[0064] In one embodiment, see Figure 6 , the heating element 200 is sealed and installed in the atomizing section 121 through the sealing member 300. Specifically, the sealing member 300 is installed in the inner cavity of the atomizing section 121, and the sealing member 300 is sleeved on the outer periphery of the heating element 200, and the outer wall of the sealing member 300 is respectively abutted against the inner wall of the atomizing section 121 and the mounting seat 110, so that the sealing member 300 realizes the sealed connection between the heating element 200 and the atomizing section 121 and the mounting seat 110. Specifically, the sealing member 300 is supported on the support plate 111, and the bottom of the sealing member 300 is abutted against the support plate 111.

[0065] In one embodiment, see Figure 6 and Fig.13 The sealing member 300 is formed with a receiving groove 310, which has a bottom wall and a peripheral side wall. The heating element 200 is received in the receiving groove 310, and the bottom side of the heating element 200 abuts against the bottom wall of the receiving groove 310, and the peripheral side wall of the heating element 200 abuts against the peripheral side wall of the receiving groove 310, so that the heating element 200 is sealed and installed in all directions through the sealing member 300. The bottom wall of the receiving groove 310 is formed with a connecting groove 320, which is connected to the buffer bin 170, and the oil in the oil bin 140 enters the heating element 200 through the buffer bin 170 and the connecting groove 320.

[0066] In one embodiment, see Figure 6 and Fig.13 The seal 300 is semi-cylindrical, and is received in the buffer bin 170. The bottom of the seal 300 is supported on the support plate 111 of the mounting seat 110, and the top of the seal 300 is in contact with the step plate 123. The heating element 200 is mounted on the straight side wall of the seal 300, and the circular side wall of the seal 300 is in contact with the inner circumferential wall of the atomizing section 121. The top of the seal 300 forms a connecting port 330 that is directly connected to the through port 1231. The oil in the oil bin 140 enters the seal 300 through the through port 1231 and the connecting port 330 in turn, so that it is absorbed by the heating element 200 and atomized. In addition, the semi-cylindrical design of the seal 300 can also make the mounting seat 110 and the atomizing section 121 sealed and connected.

[0067] In one embodiment, see Fig.12 and Fig.13 The position of the sealing member 300 above the enclosure 112 of the mounting seat 110 is avoided, so that the atomizing section 121 corresponding to the sealing member 300 can be directly sleeved on the sealing member 300. In addition, two positioning blocks 114 are formed on the enclosure 112, and two positioning grooves 340 are formed on the outer peripheral wall of the sealing member 300. The positioning blocks 114 and the positioning grooves 340 both extend along the axial direction of the mounting seat 110, and the positioning blocks 114 and the positioning grooves 340 are plugged and matched, thereby forming the installation positioning of the sealing member 300.

[0068] In one embodiment, see Figure 6 and Fig.10 When the airway wall 165 of the ventilation channel 160 is arranged horizontally opposite to the atomizing surface 220 of the heating element 200, the ventilation channel 160 is formed by the atomizing section 121, the oil pipe 130 and the mounting seat 110. Specifically, a first ventilation groove 1211 is formed on the outer peripheral wall of the atomizing section 121, the first ventilation groove 1211 extends along the axial direction of the atomizing section 121 and passes through the axial ends of the atomizing section 121, and the first ventilation groove 1211 is opened toward the oil pipe 130; a second ventilation groove (not shown) is formed on the bottom wall of the atomizing section 121, the second ventilation groove is vertically connected to the first ventilation groove 1211, and the second ventilation groove is opened toward the mounting seat 110, so that the above ventilation channel 160 is formed by the atomizing section 121, the oil pipe 130 and the mounting seat 110.

[0069] In one embodiment, see Fig. 9 and Fig.12 When the ventilation channel 160 is formed by at least the housing assembly 100 and the heating element 200, since the atomizing surface 220 of the heating element 200 is a plane, the ventilation channel 160 formed by the heating element 200 and the housing assembly 100 is semi-cylindrical. Similarly, the air inlet end 161 of the ventilation channel 160 is also semi-circular.

[0070] In one embodiment, see Fig. 9 The length extension direction of the ventilation channel 160 is arranged parallel to the atomization surface 220 of the heating element 200, and the heating element 200 runs through the entire ventilation channel 160. In this way, the gas will be heated after entering the ventilation channel 160, and will be heated until the gas flows out of the ventilation channel 160, which increases the heating time of the gas, improves the problem of the gas, and improves the ability of the gas to promote the fluidity of the e-liquid.

[0071] In one embodiment, see Fig. 9 , Fig.12 and Fig.14The mounting seat 110 includes an electrode block 115, and the electrode block 115 is attached to the atomizing surface 220 of the heating element 200. The sealing member 300 includes an extension portion 350 that is sealed and abutted against the electrode block 115 and the step plate 123. The step plate 123, the extension portion 350, the electrode block 115 and the heating element 200 are together enclosed to form a ventilation channel 160. In this embodiment, by arranging the electrode block 115 on the mounting seat 110, the mounting seat can also be used as a part of the electrode, thereby reducing the number of electrodes. At the same time, by abutting the extension portion 350 between the electrode block 115 and the step plate 123, the sealing between the electrode block 115 and the step plate 123 can be improved, that is, the air tightness of the entire ventilation channel 160 is improved, so that its fluidity is better.

[0072] In one embodiment, see Fig.12 The electrode block 115 is formed with a third ventilation groove 1151 and a fourth ventilation groove 1152 which are vertically connected to each other. The third ventilation groove 1151 and the fourth ventilation groove 1152 are both semi-cylindrical. The third ventilation groove 1151 and the fourth ventilation groove 1152 are both opened toward the heating element 200. The heating element 200 is disposed against the side surfaces of the third ventilation groove 1151 and the fourth ventilation groove 1152. Fig.13 The extension portion 350 is formed with a fifth ventilation groove 351, which is connected to the third ventilation groove 1151. Fig.15 A ventilation hole 1232 is formed on the step plate 123 of the cigarette bomb tube 120, and the ventilation hole 1232 is connected to the fifth ventilation groove 351, so that the ventilation channel 160 can be formed by the step plate 123, the extension part 350, the electrode block 115 and the heating element 200.

[0073] In addition, when the ventilation channel 160 has two branch channels 164, please refer to Fig.16 Two fourth ventilation grooves 1152 are formed on the electrode block 115 .

[0074] In one embodiment, see Figure 6 The atomizer assembly 1000 also includes a connecting electrode 400 and an electrode holder 500. The electrode holder 500 is disposed in the mounting seat 110. The connecting electrode 400 is mounted on the electrode holder 500. The connecting electrode 400 and the electrode block 115 are electrically connected to two connecting parts on the heating element 200, respectively. The mounting seat 110 and the connecting electrode 400 are electrically connected to the battery assembly 2000, respectively, so that the heating element 200 can be powered by the battery assembly 2000.

[0075] In one embodiment, see Figure 3 The cigarette cartridge tube 120 and the oil tube 130 are both sealed and connected to the suction nozzle 3000 through the sealing sleeve 4000.
