During specific use, each time the user inhales the aerosol, aerosol will remain in the atomizer, and the condensate formed after the residual aerosol condenses is more likely to leak out of the atomizer. To this end, as described in the Chinese patent application number CN202010895823.0, those skilled in the art set up a number of adsorption grooves on the outside of the atomizer to adsorb and store the leaked condensate through the several adsorption grooves.

For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products, or devices.

[0036] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0037] The present application is described in detail below with reference to the accompanying drawings and embodiments.

[0038] See also Figures 1 to 4 ,in, Figure 1 This is a disassembled schematic diagram of the atomizer 1 provided in one embodiment of the present application; Figure 2 A disassembly diagram of an atomizer 1 is provided for another embodiment of the present application;

[0039] Figure 3 for Figure 1 AA section view; Figure 4 for Figure 1 BB cross-sectional view; in this embodiment, an atomizer 1 is provided. When powered, the atomizer 1 is configured to heat and atomize an aerosol-generating substrate to form an aerosol for inhalation by a user. The aerosol-generating substrate may be a liquid containing a drug dispersed in a liquid solvent, an oil with added aroma components, or any other liquid suitable for electronic atomization.

[0040] like Figures 1 to 4 As shown, the atomizer 1 includes a first shell 11, a base 12, a bracket 13 and an atomizing core 14. The first shell 11 is formed with a mouthpiece 111, an airway 112 connected to the mouthpiece 111, a liquid storage chamber 113 for storing an aerosol generating matrix, and a first foolproof structure 114 (see below) provided on the outer side of the side wall of the first shell 11. Figure 6 At least a portion of the base 12 is disposed within the first housing 11, and a liquid storage structure is disposed on the outer side of the sidewall of the base 12 for storing aerosol condensate. In one embodiment, the liquid storage structure is a liquid storage member disposed on the outer side of the sidewall of the base 12. The liquid storage member can be absorbent cotton, such as a sponge or cotton cloth.

[0041] The bracket 13 is disposed in the first housing 11 and is Figure 4As shown, the bracket 13 includes an embedded portion 131 and a cover portion 132 that are connected to each other. The embedded portion 131 of the bracket 13 is inserted into the base 12 and cooperates with the base 12 to form an atomization chamber. The atomization chamber is located on the inner side of the side wall of the base 12 and is isolated from the liquid storage structure, that is, the atomization chamber and the liquid storage structure are spaced apart. Furthermore, at least a portion of the side wall of the embedded portion 131 is spaced apart from the side wall of the base 12 to define a first air outlet channel 1311. The first air outlet channel 1311 is connected to the airway 112, and the aerosol formed by atomization in the atomization chamber flows out to the airway 112 via the first air outlet channel 1311. Furthermore, the first air outlet channel 1311 is also connected to the liquid storage structure; in this way, after each user inhales the aerosol, the aerosol remaining in the airway 112, the first air outlet channel 1311 and the atomization chamber, and the condensate formed therefrom are more likely to flow to the liquid storage structure for storage, effectively reducing the probability of leakage of the aerosol condensate. Specifically, the number of the first air outlet channels 1311 and the liquid storage structure can be two, and the two first air outlet channels 1311 and the two liquid storage structures are arranged in a one-to-one correspondence along the radial direction of the base 12, so that the condensed liquid formed after the aerosol flowing out of the first air outlet channels 1311 is condensed can be stored in the liquid storage structure as much as possible, thereby reducing the risk of leakage.

[0042] Please continue reading Figure 4 The cover 132 is located outside the base 12 and abuts against the end of the side wall of the base 12 facing the cover 132; and a notch 1321 is formed at the position where the cover 132 abuts against the side wall of the base 12, and the notch 1321 connects the first air outlet channel 1311 and the liquid storage structure. In a specific embodiment, the cover 132 is also provided with a drainage wall, which is provided on at least one side of the notch 1321. The drainage wall extends from the first air outlet channel 1311 to the liquid storage structure and is used to guide the condensate to the liquid storage structure. Specifically, the end of the side wall of the base 12 abuts against the drainage wall, and the drainage wall is provided with a liquid guide surface, which is connected to the wall surface of the first air outlet channel 1311 to guide the condensate on the wall surface of the first air outlet channel 1311 to the outside of the side wall of the base 12. Of course, in other embodiments, the notch 1321 can also be formed by the end of the side wall of the base 12 being recessed in the direction away from the cover portion 132; or, the end of the side wall of the base 12 is recessed in the direction away from the cover portion 132 to form a first arcuate groove, and the position where the cover portion 132 abuts the end of the side wall of the base 12 is recessed in the direction away from the base 12 to form a second arcuate groove, and the first arcuate groove and the second arcuate groove cooperate to form the notch 1321.

[0043] By setting the notch 1321 at the connection between the cover portion 132 and the embedded portion 131, it is not only easy to manufacture, but also after the user stops inhaling, the residual aerosol can quickly flow out from the notch 1321 and form condensate to be stored in the liquid storage structure, effectively reducing the probability of residual aerosol overflowing from other gaps in the base 12 or the bracket 13 to form condensate, causing leakage.

[0044] Specific, combined Figure 1 and Figure 4 The cover 132 is further formed with a second air outlet channel 1327, a third air outlet channel 1328, and an air outlet 1322. The second air outlet channel 1327 extends along the transverse direction of the cover 132, with a first end of the second air outlet channel 1327 communicating with the first air outlet channel 1311, and a second end of the second air outlet channel 1327 communicating with the third air outlet channel 1328. The third air outlet channel 1328 extends along a longitudinal direction S perpendicular to the circumference of the base 12 and communicates with the air outlet 1322. The first air outlet channel 1311, the second air outlet channel 1327, and the third air outlet channel 1328 form the air outlet channel of the atomizer 1. The air outlet 1322 is located at the end of the cover 132 facing away from the embedded portion 131 and communicates with the air passage 112. The aerosol formed by atomization in the atomization chamber flows out through the atomization chamber, the air outlet channel, the air outlet 1322, the air passage 112, and the mouthpiece 111 in sequence. Among them, by providing the extended second air outlet channel 1327 and the third air outlet channel 1328, the path of the aerosol reaching the suction nozzle 111 can be extended, thereby reducing the temperature of the aerosol to a certain extent, thereby avoiding the problem of burning the mouth when sucking.

[0045] like Figure 4 As shown, the atomizing core 14 is located in the embedded portion 131 and between the two first air outlet channels 1311, and is used to heat and atomize the aerosol generating matrix when powered on to form an aerosol for the user to inhale. The first air outlet channel 1311 is specifically located between the atomizing core 14 and the liquid storage structure. Among them, the specific structure and function of the atomizing core 14 are the same or similar to the specific structure and function of the atomizing core in the existing atomizer, and can achieve the same or similar technical effects. For details, please refer to the prior art and will not be repeated here. It can be understood that as long as the aerosol generating matrix can be atomized, the structure of the atomizing core is not specifically limited here.

[0046] In another specific embodiment, Figure 1 and Figure 4As shown, the liquid storage structure is a liquid storage tank 121 arranged on the outside of the side wall of the base 12, and the notch of the liquid storage tank 121 is arranged along the longitudinal direction S perpendicular to the circumference of the base 12 toward the direction of the air outlet 1322; and the liquid storage tank 121 is connected to the first air outlet channel 1311 through the notch 1321 on the cover 132. In this way, when the atomizer 1 is placed vertically and the mouthpiece 111 is facing upward, the condensate can only overflow from the notch of the liquid storage tank 121 when the condensate fills the entire liquid storage tank 121, resulting in a larger storage space and a larger amount of liquid collected. It is understandable that if the notch of the liquid storage tank 121 is arranged toward the inner wall of the first shell 11, the condensate may overflow as long as it submerges the bottom wall of the liquid storage tank 121 (that is, along the longitudinal direction S perpendicular to the circumference of the base 12, the liquid storage tank 121 is away from the side wall of the cover 132), and the storage capacity of the condensate is small. Therefore, compared with the solution of setting the opening of the liquid storage tank 121 toward the inner wall surface of the first shell 11, the solution provided by this embodiment allows the aerosol condensate to be easily stored in the liquid storage tank 121 and is not easy to leak out, thereby greatly reducing the probability of leakage of the condensate.

[0047] In addition, the above-mentioned solution does not provide a top wall on the side of the liquid storage tank 121 facing the air outlet 1322, that is, directly forms an open notch. Compared with the solution of providing a top wall on the side of the liquid storage tank 121 facing the air outlet 1322 and opening a through hole on the top wall for the aerosol condensate flowing out of the notch 1321 to flow in, in the embodiment of the application, since the diameter of the notch is larger than the aperture of the through hole, the alignment between the notch and the notch 1321 along the longitudinal direction S perpendicular to the circumference of the base 12 is easier to achieve, and the processing requirements for the liquid storage tank 121 are relatively low. It can effectively ensure that the aerosol condensate flowing out of the notch 1321 flows directly into the liquid storage tank 121 through the notch under the action of gravity, avoiding the problem of the through hole and the notch 1321 not being aligned along the longitudinal direction S perpendicular to the circumference of the base 12, and the aerosol condensate flowing on the top wall of the liquid storage tank 121 and leaking.

[0048] Of course, in other embodiments, the side of the liquid reservoir 121 facing the air outlet 1322 along the longitudinal direction S perpendicular to the circumference of the base 12 may also be provided with a top wall, that is, without a notch, to form a closed cavity. This can, to a certain extent, prevent the problem of condensate stored in the liquid reservoir 121 leaking out of the notch when the atomizer 1 is tilted. In this embodiment, a hole can be directly opened in the common side wall 122 to connect the liquid reservoir 121 and the first air outlet channel 1311; alternatively, a hole can be opened in the top wall of the liquid reservoir 121 at a position corresponding to the notch 1321 to connect the liquid reservoir 121 and the first air outlet channel 1311.

[0049] Specifically, such as Figure 4As shown, a portion of the sidewall of the base 12 is a common sidewall 122, which serves as a sidewall of both the liquid reservoir 121 and the first air outlet channel 1311. In this embodiment, a notch 1321 is formed at a location on the cover 132 where it abuts the common sidewall 122, thereby directly connecting the liquid reservoir 121 and the first air outlet channel 1311. The above-mentioned solution saves costs by making the liquid storage tank 121 and the first air outlet channel 1311 share a side wall. Moreover, compared with the solution in which the liquid storage tank 121 and the first air outlet channel 1311 are spaced apart along the transverse direction of the base 12, the straight-line distance between the liquid storage tank 121 and the first air outlet channel 1311 along the transverse direction of the base 12 is shorter. This can effectively shorten the path of the aerosol condensate in the first air outlet channel 1311 flowing through the notch 1321 to reach the liquid storage tank 121, thereby reducing the condensation of residual aerosol in the notch 1321, thereby avoiding the problem of aerosol condensate clogging the notch 1321.

[0050] In a specific embodiment, in order to further reduce the risk of leakage of the atomizer 1; Figure 2 As shown, the outer sidewalls of the base 12 are further provided with a plurality of liquid collection grooves 123. The openings of the plurality of liquid collection grooves 123 face the first housing 11, and the plurality of liquid collection grooves 123 are each connected to the liquid storage structure. This allows the condensate in the liquid collection grooves 123 to flow into the liquid storage structure when the amount of condensate is high, thus preventing leakage from the openings of the liquid collection grooves 123. Specifically, the plurality of liquid collection grooves 123 are evenly distributed on both sides of the liquid storage structure, and the liquid collection grooves 123 on each side are spaced apart along a longitudinal direction S perpendicular to the circumference of the base 12.

[0051] like Figure 2As shown, the cover portion 132 of the bracket 13 is also provided with a ventilation hole 1324 and a ventilation groove 1323 connected to the ventilation hole 1324; wherein, the ventilation hole 1324 is located on the side of the cover portion 132 away from the base 12, and is connected to the space on the side of the cover portion 132 away from the base 12; the ventilation groove 1323 is provided on the outer periphery of the cover portion 132, and is connected to the liquid storage chamber 113 through the ventilation hole 1324, and is used for ventilation of the liquid storage chamber 113 to maintain the air pressure balance inside and outside the liquid storage chamber 113, so as to facilitate liquid discharge. The ventilation groove 1323 is also provided with a vent 1325, which is connected to the liquid storage structure through the vent 1325. This allows the aerosol-generating substrate within the liquid storage chamber 113 to flow through the vent 1325 for storage. Alternatively, if aerosol condensation forms within the ventilation groove 1323, the condensation can flow through the vent 1325 into the liquid storage structure for storage. This prevents the aerosol-generating substrate or condensation from clogging the ventilation groove 1323, leading to a lack of ventilation. This also prevents the condensation or aerosol-generating substrate within the ventilation groove 1323 from being pushed into the liquid storage chamber 113 by external air due to a pressure differential, thereby affecting the aerosol-generating substrate within the liquid storage chamber 113 and causing its deterioration, which in turn affects the aerosol's taste when inhaled.

[0052] Specifically, such as Figure 2 As shown, along the longitudinal direction S, which is perpendicular to the circumference of the base 12, the height of the ventilation groove 1323 is higher than the height of the liquid storage structure. This facilitates the direct flow of the aerosol-generating substrate and / or aerosol condensate within the ventilation groove 1323 into the liquid storage structure under the action of gravity. Furthermore, the height of the vent 1325 is also higher than the height of the liquid storage structure. This makes the vent 1325 less likely to be clogged by the aerosol-generating substrate and / or aerosol condensate, allowing leaked aerosol-generating substrate and / or condensate within the ventilation groove 1323 to flow more easily into the liquid storage structure.

[0053] Specifically, the transverse cross-sectional area of ​​the ventilation grooves 1323 gradually increases along the airflow direction of the ventilation grooves 1323; or the transverse cross-sectional area of ​​the portion of the ventilation grooves 1323 close to the liquid storage chamber 113 is larger than the transverse cross-sectional area of ​​the portion of the ventilation grooves 1323 away from the liquid storage chamber 113. In this way, the ventilation grooves 1323 are less likely to be blocked by leaked aerosol-generating substrate or condensed liquid, and the ventilation effect is improved.

[0054] In a specific embodiment, if Figure 2As shown, the ventilation groove 1323 includes at least one first groove 132a and at least one second groove 132b extending along the circumference of the cover portion 132. The first groove 132a and the second groove 132b are each recessed toward the center of the cover portion 132. The first groove 132a communicates with the ventilation hole 1324, while the at least one second groove 132b communicates with both the first groove 132a and the liquid storage structure. The at least one second groove 132b is located between the at least one first groove 132a and the liquid storage structure along a longitudinal direction S perpendicular to the circumference of the base 12. The transverse cross-sectional area of ​​the first groove 132a is greater than that of the second groove 132b. This prevents the first groove 132a from becoming clogged, which would affect the ventilation effect of the ventilation groove 1323. The area of ​​the first groove 132a along the direction of the bracket 13 away from the base 12 can be greater than 0.6 mm.

[0055] Specifically, such as Figure 2 As shown, two adjacent first grooves 132a, two adjacent second grooves 132b, and two adjacent first grooves 132a and second grooves 132b are connected through a connecting hole 1326. Among them, two adjacent connecting holes 1326 and the connecting hole 1326 and the vent 1325 can be staggered along the longitudinal direction S perpendicular to the circumference of the base 12.

[0056] Of course, in other specific embodiments, such as Figure 5 As shown, each connecting hole 1326 and the vent 1325 can also be aligned along the longitudinal direction S perpendicular to the circumference of the base 12; this enables the condensed liquid in the first groove 132a to flow smoothly to the second groove 132b, and flow to the liquid storage tank 121 through the vent 1325 for storage, preventing the condensed liquid or aerosol generating matrix in the first groove 132a and / or the second groove 132b from clogging the ventilation groove 1323 or being pushed into the liquid storage cavity 113 by external gas and affecting the aerosol generating matrix in the liquid storage cavity 113, causing it to deteriorate, thereby affecting the taste of the aerosol when inhaled. It can be understood that the aerosol that is not inhaled by the user flows to the liquid storage tank 121, the liquid accumulation tank 123 and the ventilation tank 1323 to form condensate stored in these tanks. When the ventilation tank 1323 is filled with these condensates, the ventilation effect of the ventilation tank 1323 will be affected; and under the action of the pressure difference, the gas will reach the ventilation hole 1324 by the shortest route. At this time, part of the condensate in the ventilation tank 1323 will be pushed into the liquid storage chamber 113 by the gas. Therefore, making the gas go in a straight line as much as possible can reduce the gas pushing the condensate and destroying the ventilation effect.

[0057] In a specific embodiment, please continue to refer to 5. A connecting groove 1231 is provided on the groove wall of at least one of the multiple liquid accumulation grooves 123, and the liquid accumulation groove 123 is connected with the second groove 132b and the first groove 132a through the connecting groove 1231 and the connecting hole 1326; in this way, the condensate or leaked aerosol generating matrix in the first groove 132a and the second groove 132b can be further flowed out to the liquid accumulation groove 123 for storage through the connecting hole 1326 and the connecting groove 1231, so as to further prevent the ventilation groove 1323 from being blocked, and make the ventilation of the ventilation groove 1323 more unobstructed.

[0058] Specifically, along the longitudinal direction S perpendicular to the circumference of the base 12, several liquid accumulation grooves 123 are located below the second ventilation groove 1323, and a connecting groove 1231 is provided on each groove wall of the several liquid accumulation grooves 123, and several connecting grooves 1231 on the same side are aligned along the longitudinal direction S perpendicular to the circumference of the base 12, so that the aerosol generating matrix or condensate flowing in from the ventilation groove 1323 can smoothly pass through the through hole connecting the liquid accumulation groove 123 and the liquid storage structure under the action of gravity and flow into the liquid storage structure for storage; in this way, when the amount of aerosol generating matrix or condensate flowing in from the ventilation groove 1323 is large, the problem of leakage of these aerosol generating matrix or condensate in the liquid accumulation groove 123 can be avoided as much as possible.

[0059] Of course, in other embodiments, the ventilation groove 1323 may also be spirally wrapped around the outer side wall of the cover portion 132 along the circumference of the cover portion 132. The present application does not impose any restrictions on this, as long as the transverse cross-sectional area of ​​the ventilation groove 1323 gradually increases along the airflow direction of the ventilation groove 1323; or the transverse cross-sectional area of ​​the portion of the ventilation groove 1323 close to the liquid storage chamber 113 is larger than the transverse cross-sectional area of ​​the portion of the ventilation groove 1323 away from the liquid storage chamber 113.

[0060] Specifically, such as Figures 1 to 4As shown, the atomizer 1 also includes a sealing seat 15, a sealing cover 16, a first electrode 17, a second electrode 18, a first magnetic member 19 and a sealing ring. Among them, the sealing seat 15 is arranged between the atomizing core 14 and the embedding portion 131, and is used to seal the gap between the atomizing core 14 and the embedding portion 131 to prevent the aerosol-generating matrix that enters the atomizing core 14 from the liquid storage chamber 113 from flowing out from the gap between the two. The sealing cover 16 is provided on the end of the cover portion 132 away from the embedding portion 131, and part of the sealing cover 16 is located between the inner wall surface of the first shell 11 and the side wall of the cover portion 132 to seal the liquid storage chamber 113 and prevent leakage. The first electrode 17 and the second electrode 18 are electrically connected to the atomizing core and are respectively used to electrically connect to the electrodes on the power supply assembly 2 to achieve electrical connection between the atomizer 1 and the power supply assembly 2. The first magnetic member 19 is provided at the end of the base 12 away from the bracket 13, and is used to connect to the second magnetic member 24 (see below) on the battery assembly. Figure 8 ) to securely secure the atomizer 1 and the power supply assembly 2. The first magnetic member 19 and the second magnetic member 24 can be magnets. The specific structures and functions of the sealing seat 15, sealing cover 16, first electrode 17, and second electrode 18 can refer to the specific structures and functions of the relevant components in the existing atomizer 1, and can achieve the same or similar technical effects, so they will not be repeated here.

[0061] The atomizer 1 provided in this embodiment is provided with a base 12 and a bracket 13, and a liquid storage structure is provided on the outer side of the side wall of the base 12. The bracket 13 and the base 12 cooperate to form an air outlet channel connecting the atomizing chamber and the air outlet 1322 of the bracket 13; at least a portion of the air outlet channel is located between the atomizing core 14 and the liquid storage structure and is connected to the liquid storage structure; in this way, the residual aerosol condensate can more easily flow through the air outlet channel to the liquid storage structure for storage, effectively reducing the probability of leakage of the aerosol condensate.

Figure 7 As shown, the fixing frame 22 is disposed within the second housing 21 and defines a power supply cavity and a plug slot with the second housing 21. The power supply 23 is housed within the power supply cavity and is connected to the plurality of power supply electrodes. The power supply 23 may be a battery.

[0064] The atomizer 1 is inserted into the socket, and the first electrode 17 and the second electrode 18 of the atomizer 1 are electrically connected to the first power supply electrode 26 and the second power supply electrode 27, respectively, to achieve electrical connection between the power supply assembly 2 and the atomizer 1. The control circuit is electrically connected to the first power supply electrode 26 and the second power supply electrode 27, respectively, and is used to output a corresponding power supply voltage to the atomizer 1 based on the conduction between the first power supply electrode 26 and the second power supply electrode 27.

[0065] like Figure 6 As shown, the second foolproof structure 25 is formed inside the second housing 21 and is located in the insertion slot. The atomizer 1 is inserted into the power supply assembly 2 through the cooperation of the first foolproof structure 114 and the second foolproof structure 25 to limit the relative position of the atomizer 1 and the power supply assembly 2, facilitating the alignment of the power supply electrode on the atomizer 1 with the electrode on the power supply assembly 2 to achieve effective electrical connection between the two and output the corresponding supply voltage. The first foolproof structure 114 and the second foolproof structure 25 can be a combination of a slide groove and a slide rail, or a combination of a protrusion and a pit.

[0066] Of course, the electronic atomization device 10 also includes other structures such as a sealing ring, an air inlet, and a liquid outlet. These structures can refer to the relevant structures and functions in the existing electronic atomization device for details, and can achieve the same or similar technical effects, so they will not be repeated here.
