This application will be explained in detail below in conjunction with the accompanying drawings and embodiments.
In a specific embodiment of this application, an electronic atomization device is provided. The electronic atomization device is configured to heat and atomize an atomizable matrix when powered on, to generate aerosols for use by a user. The electronic atomization device is applicable to different fields, such as medical treatment, beauty treatment, or recreational smoking, etc. The atomizable matrix can be an oily matter composed of glycerol, propylene glycol, essence, flavor and the like, or liquid formed by dispersing some drugs in a solvent.
Referring to FIG. 1 to FIG. 3, FIG. 1 is a schematic diagram of an overall structure of an electronic atomization device according to an embodiment of this application; FIG. 2 is a schematic diagram of an exploded structure of an electronic atomization device according to an embodiment of this application; and FIG. 3 is a cross-sectional view of direction A-A of FIG. 1.
In this embodiment, the electronic atomization device 100 includes a battery cell 32, a holder 40, and an atomization assembly 2. The battery cell 32 is assembled on the holder 40 and is configured to supply power to the atomization assembly 2, so that the atomization assembly 2 heats and atomizes an atomizable matrix.
Further, the electronic atomization device 100 further includes a liquid storage cavity housing 11 and a shell 50. A portion of the liquid storage cavity housing 11 is fixed in the shell 50 and cooperates with the atomization assembly 2 to form a liquid storage cavity 1, so as to accommodate the atomizable matrix through the liquid storage cavity 1. The atomization assembly 2 is arranged in the liquid storage cavity housing 11. Meanwhile, the battery cell 32 and the holder 40 are received together in the shell 50. It can be understood that after the assembling is completed, the product is non-removable and can be discarded immediately after use, making it a disposable product. Compared with a recyclable product, this product can simplify the assembled structure to an extent, which is conducive to mass production. Moreover, the product is easy to use and can effectively reduce the harm caused by the residues to a human body.
In this embodiment, the holder 40 includes a base body 24 and a mounting frame 30 arranged on one side of the base body 24. The base body 24 is connected to the liquid storage cavity housing 11 or the atomization assembly 2, is covered at an open end of the liquid storage cavity housing 11, and further cooperates with the liquid storage cavity housing 11 to fix the atomization assembly 2 in the liquid storage cavity housing 11. Specifically, a mounting cavity is arranged in one end of the holder 40 facing away from the atomization assembly 2, namely, the mounting cavity is arranged in one end of the mounting frame 30 away from the base body 24. The battery cell 32 is at least partially assembled in the mounting cavity of the mounting frame 30 to fix the battery cell 32, thereby avoiding the problem of short circuit, open circuit, and the like between the battery cell 32 and the atomization assembly or another connector due to offset. In this embodiment, the mounting cavity is an annular frame. The specific shape of the annular frame can be set according to the appearance of the battery cell 32. Moreover, an air inlet gap is formed between the battery cell 32 and the inner wall of the shell 50. When a user inhales, an airflow can enter an air inlet channel 302 of the holder 40 along the air inlet gap, and then enter the atomization assembly 2 through the air inlet channel 302. Specifically, the electronic atomization device further includes an airflow sensor 31. The airflow sensor 31 is arranged on the mounting frame 30. The airflow sensor 31 is configured to turn on the electronic atomization device 100 after sensing a change in the airflow or an air pressure, to turn on an atomization path, thereby turning on the electronic atomization device 100.
Specifically, referring to FIG. 4 and FIG. 5, FIG. 4 is a schematic structural diagram of one side of a holder according to an embodiment of this application; and FIG. 5 is a schematic structural diagram of the other side of a holder according to an embodiment of this application. In this embodiment, the holder 40 includes a base body 24 and a mounting frame 30 arranged on one side of the base body 24. Specifically, an accommodating cavity 301 for accommodating an airflow sensor 31 is arranged on one side of the mounting frame 30. The accommodating cavity 301 can be specifically a groove, and its shape and size can be matched according to the shape and size of the airflow sensor 31, without a limitation. The airflow sensor 31 can be specifically an airflow sensor, an air pressure sensor, a microphone, or another sensor that can sense a change in the airflow. In this embodiment, the microphone is preferably used as the airflow sensor 31. On the other side of the mounting frame 30, an air inlet channel 302 is arranged at one end close to the base body 24. The air inlet channel 302 is communicated to an air inlet hole 241 on the base body 24, so that the airflow can smoothly enter the atomization assembly 2 through the air inlet channel 302 from the air inlet hole 241, to ensure an unblocked airflow. Further, the mounting frame 30 is further provided with a detection air hole 303 that communicates the air inlet channel 302 with the accommodating cavity 301. The detection air hole 303 is specifically a through hole, so that when the airflow passes through the air inlet channel 302, the airflow sensor 31 in the accommodating cavity 301, facing away from the air inlet channel 302, on the mounting frame 30 can sense the change in the airflow through the detection air hole 303. The aperture size of the detection air hole 303 can be set in a matched manner according to the sensitivity of the airflow sensor 31, without a specific limitation.
According to the electronic atomization device 100 provided in this embodiment, by the arrangement of the holder 40 and the airflow sensor 31, the mounting frame 30 of the holder 40 is arranged on one side of the base body 24; the airflow sensor 31 is arranged in the accommodating cavity 301 of the mounting frame 30; and the base body 24 and the mounting frame 30 are integrated. Therefore, the base body 24, the mounting frame 30, and the accommodating cavity 301 are connected without additional connectors, which simplifies the overall structure and manufacturing process of the electronic atomization device 100 and facilitates carrying and use. Meanwhile, the air inlet channel 302 is arranged on the other side of the mounting frame 30 to communicate the air inlet hole 241 in the base body 24, and the air inlet channel 302 is communicated to the accommodating cavity 301 through the detection air hole 303, so that the airflow sensor 31 in the accommodating cavity 301 can sense the change in the airflow in the air inlet channel 302 through the detection air hole 303, thereby achieving electrical turning on and turning off of the electronic atomization device 100.
Further, a cut-off portion 3021 is further arranged in the air inlet channel 302. The detection air hole 303 is located on one side of the cut-off portion 3021 facing the air inlet hole 241. This can reduce the air inlet area of the airflow at the position of the cut-off portion 3021 in the air inlet channel 302, so that a negative pressure is easily generated in a cavity between the cut-off portion 3021 in the air inlet channel 302 and the air inlet hole 241 during inhalation. This makes it easier for the airflow sensor 31 to sense the negative pressure through the detection air hole 303 and be switched on, thereby achieving electrical turning on and turning off of the electronic atomization device 100. Furthermore, at the beginning of inhalation or at the stop of inhalation, an air pressure difference in the cavity between the cut-off portion 3021 and the air inlet hole 241 changes greatly, so that the air pressure is more easily sensed by the airflow sensor 31, which effectively improves the sensitivity of the electronic atomization device 100. Even if the sensitivity of the airflow sensor 31 itself is low, the airflow sensor can reliably sense an inhalation action of a user, thereby effectively improving the reliability of the electronic atomization device 100.
Referring to FIG. 5 and FIG. 6, FIG. 6 is a cross-sectional view of direction B-B of FIG. 1. Specifically, the air inlet channel 302 on the mounting frame 30 is an air inlet groove. When the holder 40 is arranged in the shell 50, the inner wall of the shell 50 covers the air inlet groove and forms a cavity with the air inlet channel 302, so that the airflow can enter the atomization assembly 2 along the air inlet channel 302. A distance between the cut-off portion 3021 in the air inlet groove and the inner wall of the shell 50 ranges from 1.0 mm to 1.5 mm, which can be selected according to an actual need, to adjust the air inlet area at the position of the cut-off portion 3021 in the air inlet channel 302, thereby adjusting the sensitivity of the electronic atomization device 100 for sensing the airflow and the inhalation resistance during inhalation, so as to achieve the best effect during use of the electronic atomization device.
In another embodiment, the electronic atomization device 100 may further include a cover element (not shown). The cover element is attached to the air inlet groove, and a distance between the cut-off portion 3021 and the cover element ranges from 1.0 mm to 1.5 mm. It is easily understood that the cover element here serves as the shell, and the distance between the cut-off portion 3021 and the cover element can be adjusted by adjusting the distance between the cover element and the holder 40 or the thickness of the cover element, to adjust the air inlet area in the air inlet channel 302, so that the sensitivity of the electronic atomization device 100 is best.
Referring to FIG. 5 again, in this embodiment, the air inlet channel 302 includes a first groove section 3022 and a second groove section 3023, namely, the air inlet groove includes the first groove section 3022 and the second groove section 3023, and the depth of the second groove section 3023 is greater than that of the first groove section 3022, so that the air inlet channel 302 is communicated to the air inlet hole 241. Specifically, the cut-off portion 3021 is arranged in the first groove section 3022; the air inlet hole 241 on the base body 24 is communicated to the second groove section 3023, and the air inlet hole 241 faces the side wall of the connection between the second groove section 3023 and the first groove section 3022. Therefore, after leaked liquid flows into the air inlet hole 241, the side wall at this position has a catching effect on the leaked liquid, which can prevent the leaked liquid from directly leaking to the detection air hole 303, causing the detection air hole 303 to be blocked and affecting the airflow sensor 31 to sense the change in the airflow. The first groove section 3022, the second groove section 3023, and the air inlet hole 241 are communicated in sequence in an airflow direction, so that the airflow can flow to the air inlet hole 241 along the first groove section 3022 and the second groove section 3023 and smoothly enter the atomization space 25 in the atomization base 20.
Further, a plurality of transverse capillary grooves, located on the two sides of the air inlet channel, are provided in the side wall of the mounting frame 30, and can be configured to absorb the aerosol condensate flowing to this position under an abnormal condition, ensuring that the electronic atomization device 100 does not leak liquid.
Referring to FIG. 2 and FIG. 7, FIG. 7 is a schematic structural diagram of a holder in a viewing angle according to an embodiment of the present disclosure. In this embodiment, a recessed portion 304 is further arranged on one side, close to the shell 50, of the bottom of the mounting frame 30 of the holder 40. A gap is formed by spacing the recessed portion 304 is apart from an inhalation hole 501 of the shell 50, and the gap is communicated to the air inlet gap between the shell 50 and the battery cell 32, so that external air can enter through the gap during inhalation and enter the air inlet channel 302 on the mounting frame 30 along the air inlet gap between the battery cell 32 and the shell 50, thereby avoiding the following problem: the holder 40 blocks the inhalation hole 501 in the shell 50, so that the external air cannot enter the air inlet channel 302, and as a result, the electronic atomization device 100 cannot be turned on, and the aerosols cannot be inhaled by a user along with the airflow because of the blocked airflow. It can be understood that the shape and size of the recessed portion 304 can be set according to an actual need. Meanwhile, no specific limitation is made on the distance between the recessed portion 304 and the inhalation hole 501. Namely, no specific limitation is made on the size of the gap, as long as the external air can smoothly enter the air inlet channel during the inhalation by a user.
In this embodiment, one end of the holder 40 directly or indirectly presses against an atomization core 22 on the atomization base 20, so that the atomization core 22 is stably fixed on the atomization base 20, which can avoid the problem such as liquid leakage or circuit breakage caused by the looseness of the atomization core 22. The holder 40 is covered at one end of the atomization space 201, the aerosols formed in the atomization space 201 can enter a user with the inhalation of the airflow, thereby avoiding air leakage of the electronic atomization device 100 and preventing the problem of liquid leakage caused by the fact that the aerosol condensate stored in the liquid storage space 203 flows to another place, thus improving the assembling reliability of the electronic atomization device 100. Moreover, the battery cell 32 is mounted at the other end of the holder 40 facing away from the atomization assembly 2 and is electrically connected to the atomization core 22, so that the battery cell 32 can supply power to the atomization core 22, thereby heating and atomizing the atomizable matrix. In addition, through the holder 40, the battery cell 32 is mounted, the atomization core 22 is fixed, and the atomization space 201 and the liquid storage space 203 are sealed, so that the electronic atomization device 100 has a simplified assembled structure, is easy to assemble, and is conducive to production.
In this embodiment, the atomization assembly 2 is specifically configured to heat and atomize the atomizable matrix. Its specific structure and function are the same or similar to those in the following embodiments, and will not be described in detail here.

The atomization assembly 2 includes a seal member 21, an atomization base 20, an atomization core 22, an electrode 23, a base 27, a liquid storage structure 25, and a liquid accumulation structure 26. The electrode 23 includes two electrodes 23 with opposite polarities. One end of each of the two electrodes 23 is electrically connected to the atomization core 22, and the other end is electrically connected to the positive and negative electrodes of the main unit to supply power to the atomization core 22 when powered on. The atomization core 22 is arranged in the atomization space 201 of the atomization base 20, and the seal member 21 covers the end portion of the atomization base 20.

In this embodiment, each electrode 23 is of a cylindrical thimble structure. One end of the electrode 23 resists against the bottom wall of the base 27 and the other end resists against the atomization core 22, so that the base 27 can press against the atomization core 22 and the atomization base 20 through the electrode 23 to fix the atomization core 22 in the atomization space 203. In another embodiment, the base 27 covers one end of the atomization base 20 to form the atomization space 203, and the atomization core 22 can be clamped in the atomization space 203 by the base 27 and/or the atomization base 20, and is pressed by one end of the base 27 close to the atomization space 203, so that the atomization core 22 is stably fixed in the atomization space 203.

In addition, the condensation slot 202 is communicated to the liquid storage space 203, so that the aerosol condensate absorbed in the condensation slot 202 can enter the liquid storage space 203 for being stored, thereby separating condensation and storage, and avoiding the problem of blockage and liquid leakage caused by a large amount of condensate accumulated in the condensation slot due to a large atomization amount. Specifically, the liquid storage space 203 is arranged at one end of the atomization base 20 in its radial direction, and the condensation slot 202 is arranged around the liquid storage space 203 and the atomization space 201 in the circumferential direction of the atomization base 20 on the outer peripheral surface of the atomization base 20, to increase the capacity of the condensation slot 202 and enlarge the area in contact with the aerosols, thereby maximizing the absorption of the aerosol condensate and enhancing the liquid leakage prevention effect of the electronic atomization device 100.
In another embodiment, the condensation slot 202 is respectively communicated to the atomization space 201 and the liquid storage space 203 in the circumferential direction of the atomization base 20, namely, one end of the condensation slot 202 is communicated to the atomization space 201 and the other end is communicated to the liquid storage space 203. It can alternatively be understood that the condensation slot 202 extends in the circumferential direction of the atomization base 20 and surrounds a portion of the atomization space 201 and a portion of the liquid storage space 203. In this way, a region is reserved on the outer peripheral surface of the atomization base 20 for the design of other structures.
In the specific embodiment, a partition wall 231 is provided between the atomization space 201 and the liquid storage space 203, so that the atomization space 201 and the liquid storage space 203 are separated by the partition wall 231, and the liquid storage space 203 and the atomization space 201 are two independent and isolated spaces. Even if the inhalation force on the atomization space 201 is increased, the aerosol condensate stored in the liquid storage space 203 will not be inhaled into the mouth of a user. The liquid storage structure 25 is arranged in the liquid storage space 203. The liquid storage structure 25 is specifically configured to store the liquid collected by the condensation slot 202, and has high collection ability for the liquid, which can avoid the stored liquid from leaking to other outlets. It can further prevent liquid leakage of an electronic atomization device with high capacity or a large atomization amount, and prevent the problem of secondary liquid leakage caused by the fact that the aerosol condensate flows from the liquid storage space 203 to another place.
It is easily understood that the aerosols are formed in the atomization space 201 of the atomization base 20. Therefore, after leaving the atomization space 201 along with the airflow, the aerosols and water vapor in the atomization space 201 may be in contact with the atomization base 20 or an airflow corner and possibly congealed into condensate. In this embodiment, a condensation slot 202 is provided on the outer peripheral surface of the atomization base 20, and the condensation slot 202 is communicated to the atomization space 201, so that the condensate is further absorbed into the condensation slot 202. Meanwhile, the condensation slot 202 is communicated to the liquid storage space 203, the condensate can enter the liquid storage space 203 through the condensation slot 202 and be stored. Moreover, a liquid storage structure 25 is arranged in the liquid storage space 203, so that the condensate and water vapor can be gathered in the liquid storage structure 25. This condenses the aerosol condensate in the condensation slot 202 and stores the aerosol condensate in the liquid storage space 203 under the condition of a large atomization amount, thus separating condensation from storage. Moreover, since the liquid storage space 203 is isolated from the atomization space 201, even if the inhalation force on the atomization space 201 is increased, the condensate stored in the liquid storage structure 25 will not be inhaled into the mouth of a user. Furthermore, the liquid storage structure 25 in the liquid storage space 203 has high collection ability on the liquid, which can avoid the leakage of the stored liquid to other outlets and effectively prevent liquid leakage of the electronic atomization device with high capacity or a large atomization amount.
Specifically, in this embodiment, the liquid storage structure 25 is a liquid storage element and is accommodated in the liquid storage space 203. A material of the liquid storage element may be specifically fibers, foam, sponge, foam ceramic, soft rubber, silica gel resin, or another material having good liquid absorption and not easily corroded by an atomizable matrix, to absorb the aerosol condensate collected in the condensation slot 202, maintain the stability of its liquid absorption performance, and avoid secondary leakage of the aerosol condensate.
In another embodiment, the liquid storage structure 25 is a capillary micro groove(s); and the capillary micro groove(s) is provided on a wall of the liquid storage space 203 and is communicated to the condensation slot 202. Specifically, the capillary micro groove(s) is provided in the inner side wall of the liquid storage space 203. The direction, width, and depth of the capillary micro groove(s) can be set according to an actual need. For example, the capillary micro groove(s) can be curved, straight, horizontal, vertical, or in other angular directions, as long as the capillary micro groove(s) can absorb the aerosol condensate collected in the condensation slot 202 through the capillary effect and store the aerosol condensate in the liquid storage space 203. No specific limitation is made here.
It is easily understood that in some other embodiments, the liquid storage structure 25 may further include a liquid storage element and a capillary micro groove(s). At least a portion of the capillary micro groove(s) is communicated to the liquid storage element, so that after the capillary micro groove(s) absorbs excess aerosol condensate, the excess aerosol condensate flows to the liquid storage element for being stored under the capillary action. This further avoids the problem of liquid leakage or inhalation of the aerosol condensate to a user end because the aerosol condensate is blocked in the condensation slot 202.
Continuing to refer to FIG. 10 and FIG. 11, in a specific embodiment, the atomization base 20 has two liquid storage spaces 203. The two liquid storage spaces 203 are arranged at the two opposite ends of the atomization base 20 in a radial direction of the atomization base 20. The atomization space 201 is located between the two liquid storage spaces 203. The atomization space 201 is isolated from the two liquid storage spaces 203 by two partition walls 231. Liquid storage structures 25 are arranged in the two liquid storage spaces 203. Namely, an internal space of the atomization base 20 is separated into three independent spaces by the two partition walls 231 that are spaced apart from each other. The middle space is the atomization space 201, and the spaces at the two ends are the liquid storage spaces 203, thereby separating the atomization space 201 from the liquid storage spaces 203. In this way, the structure of the atomization base 20 is more symmetrical, and the force on all parts is balanced. Furthermore, the aerosol condensate can be absorbed and stored to a large extent, which prevents liquid leakage of the electronic atomization device 100.
In another embodiment, the liquid storage space 203 may alternatively be arranged on the outer side of the side wall of the atomization base 20. The liquid storage space 203 is defined between the outer side wall of the atomization base 20 and the side wall of a liquid storage tank 60. A partition wall 231 is arranged on the inner wall of the atomization base 20. The partition wall 231 separates the atomization space 201 from the liquid storage space 203, so that the aerosol condensate stored in the liquid storage structure 25 is separated from the atomization space 201 and will not be inhaled to a user end.
Referring to FIG. 12, FIG. 12 is a diagram of a direction of aerosol condensate according to an embodiment of this application. In this embodiment, at least one through hole 204 is provided in the side wall of the atomization base 20. The through hole 204 communicates the liquid storage space 203 to the condensation slot 202, and the through hole 204 is a capillary hole. In a process of heating and atomizing an atomizable matrix by the electronic atomizer, after leaving the atomization space 201 along with an airflow, formed aerosols are cooled and condensed, thereby forming aerosol condensate. The aerosol condensate is absorbed by the condensation slot 202 communicated to the atomization space 201, flows to the through hole 204 under the capillary action, and then flows through the through hole 204 to the liquid storage space 203 under the capillary action again for being absorbed by the liquid storage structure 25 and stored in the liquid storage structure 25.
Specifically, at least two condensation slots 202 are provided on the side wall of the atomization base 20; the through hole 204 is provided in a spacing wall between two adjacent condensation slots 202; and the through hole 204 communicates the two adjacent condensation slots 202. The plurality of condensation slots 202 can simultaneously absorb the aerosol condensate, and the through hole 204 is provided in the spacing wall between two adjacent condensation slots 202 to communicate the two adjacent condensation slots 202. This allows the aerosol condensate collected in the two condensation slots 202 to enter the liquid storage space 203 through the through hole 204. With the same absorption and storage effects, this setting can further reduce the number of the through hole 204 and save process steps.
Certainly, in some other embodiments, the through hole 204 may alternatively be provided in the condensation slot 202, so that the aerosol condensate collected in the condensation slot 202 enters the liquid storage space 203 through the through hole 204 and is then stored in a condensation structure. It can be understood that the number and specific arrangement position of the through hole 204 that communicates the condensation slot 202 to the liquid storage space 203 can be set according to an actual need, as long as the number and the setting position can allow the aerosol condensate temporarily collected in the condensation slot 202 to enter the liquid storage space 203 under the capillary action and be stored in the liquid storage structure 25.
Further, at least one flowing opening 205 is further provided in the side wall of the atomization base 20; and the flowing opening 205 is communicated to the atomization space 201 and the condensation slot 202. An aerial fog outlet 207 is provided in the other end of the atomization base 20; the atomization base 20 is further provided with an aerial fog flow channel; and the aerial fog flow channel is communicated to the flowing opening 205 and the aerial fog outlet 207. Thus, the aerosols leave the atomization space 201 along with the airflow from the flowing opening 205 and enter the aerial fog flow channel, then flows along the aerial fog flow channel to the aerial fog outlet 207, and is inhaled to a user end through the aerial fog outlet 207. In the process that the aerosols leave the atomization space 201 along with the airflow from the flowing opening 205 and enter the aerial fog flow channel, the aerosols will be condensed due to a temperature drop, thereby forming the aerosol condensate. As the condensation slot 202 is communicated to the atomization space 201 and the aerial fog flow channel, the aerosol condensate is attached into the condensation slot 202. Under the capillary action, the aerosol condensate flows along the condensation slot 202 to the through hole 204. Under the surface tension of the liquid and the capillary action, the liquid flows through the through hole 204 to the liquid storage space 203 and is stored in the liquid storage structure 25, thus avoiding the problem of backflow of the aerosol condensate.
Further, the aerial fog flow channel is further provided with a flow guiding portion 2061 and is configured to guide the condensed atomizable matrix to the atomization core 22 arranged in the atomization space 201. This not only further reduces the possibility that the condensed atomizable matrix is inhaled to a client, but also can achieve secondary atomization on the condensed atomizable matrix and improve the utilization rate of the atomizable matrix.
Specifically, the flow guiding portion 2061 includes a plurality of flow guiding columns which are spaced apart from one another; the end portions of the flow guiding columns extend to the atomization space 201; and a flow guiding gap formed by the end portions of two adjacent flow guiding columns faces the side wall of the atomization core 22. In the process that the aerosols flow along the aerial fog flow channel to the aerial fog outlet 207, the aerosol condensate attached to the side wall of the aerial fog flow channel flows along the flow guiding portion 2061 to the end portions of the flow guiding columns, and then flows through the flow guiding gaps at the end portions to the side wall of the atomization core 22, thereby achieving secondary atomization on the aerosol condensate and further reducing the possibility of inhalation to a client and the occurrence rate of liquid leakage.
In this embodiment, the flowing openings 205 and the aerial fog flow channels are arranged in the two sides of the atomization base 20. Correspondingly, the condensation slots 202 and the flow guiding portions 2061 are arranged on the two sides too, to enlarge a contact area with the aerosol condensate. On the side wall of one side of the atomization base 20, the condensation slots 202 are arranged in the two sides of the aerial fog flow channel to further enlarge the contact area with the aerosol condensate, so that the aerosol condensate will not be inhaled or leak, and will not flow to the outside of the battery cell 32 or the device.
Further, a first liquid inlet hole 209 is further provided in one end of the atomization base 20 close to the liquid storage tank 60. One end of the first liquid inlet hole 209 is communicated to the liquid storage tank 60, and the other end is communicated to the atomization core 22, so that the atomizable matrix in the liquid storage tank 60 flows to the atomization core 22 through the first liquid inlet hole 209, to enable the atomization core 22 to heat and atomize the atomizable matrix. Specifically, the atomization base 20 is provided with two liquid inlet holes 209 respectively located on two opposite sides of the aerial fog outlet 207. The atomizable matrix flows through the two first liquid inlet holes 209 to the atomization core 22, to provide sufficient atomizable matrix for the atomization core 22, thereby ensuring a sufficient atomization amount. Meanwhile, a positioning slot 208 located on one side of each first liquid inlet hole 209 facing away from the aerial fog outlet 207 is further provided in the atomization base 20, and the positioning slot 208 is communicated to the first liquid inlet hole 209, so that the atomizable matrix in the liquid storage tank 60 can further flow through the positioning slot 208 and the first liquid inlet hole 209 to the atomization core 22, thereby heating and atomizing the atomizable matrix.
Referring to FIG. 13, FIG. 13 is a schematic structural diagram of a seal member 21 according to an embodiment of this application. In a specific embodiment, the atomization assembly 2 further includes a seal member 21 covering the end portion of the atomization base 20. Specifically, the seal member 21 is provided with a liquid collection slot 211, a liquid inlet 212, and an aerial fog port 213. Correspondingly, the aerial fog port 213 is communicated to the aerial fog outlet 207 on the atomization base 20, and the liquid inlet 212 is communicated to the first liquid inlet hole 209. A second liquid inlet hole 214 is provided in the bottom of the liquid collection slot 211, and the second liquid inlet hole 214 is communicated to the positioning slot 208 of the atomization base 20. The liquid collection slot 211 and the liquid inlet 212 are respectively communicated to the liquid storage tank 60, so that the atomizable matrix in the liquid storage tank 60 can flow into the atomization core 22 in the atomization base 20 from the liquid collection slot 211 and/or the liquid inlet 212. Specifically, the liquid collection slot 211 is of a funnel-shaped structure, so that the remaining atomizable matrix in the liquid storage tank 60 flows through the funnel-shaped liquid collection slot 211 to the second liquid inlet hole 214, and then flows through the positioning slot 208 to the atomization core 22 in the atomization base 20 for being heated and atomized, thereby reducing the remaining atomizable matrix in the liquid storage tank 60.
Further, still referring to FIG. 11, in this embodiment, the atomization assembly 2 further includes a liquid accumulation structure 26. The liquid accumulation structure 26 is configured to receive the aerosol condensate in the liquid storage structure 25. The liquid accumulation structure 26 is arranged on the base 27 and is covered at one end of the liquid storage space 203. Correspondingly, the liquid accumulation structure 26 and the liquid storage structure 25 are arranged radially opposite to each other in a radial direction of the atomization assembly 2. Preferably, the liquid accumulation structure 26 can be communicated to the liquid storage structure 25, to absorb the liquid in the liquid storage structure 25 more easily and timely, so that the liquid storage structure 25 can continue to absorb the liquid collected by the condensation slot 202, to improve the liquid storage capacity of the atomization assembly 2. Specifically, the base 27 is provided with an accommodating slot 242; the liquid accumulation structure 26 is arranged in the accommodating slot 242; the liquid accumulation structure 26 is a liquid accumulation element, similar to the liquid storage element. A material of the liquid accumulation element can be fibers, foam, sponge, foam ceramic, soft rubber, silica gel resin and another material that has good absorbency and is not easily corroded by the atomizable matrix, to further receive the aerosol condensate in the liquid storage structure 25. In another embodiment, the liquid accumulation structure 26 may be a liquid accumulation slot for receiving and storing the aerosol condensate. It is easily understood the shape and size of the liquid accumulation slot can be set according to a specific need, as long as the liquid accumulation slot can store liquid and ensure no liquid leakage.
