DETAILED DESCRIPTION

[0044] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0045] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0046] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0047] When the service life of the existing atomizer equipment reaches the end, the whole equipment needs to be replaced; the aerosol generating matrix stored in the atomizer core is prone to leakage due to excessive amount, or dry burning due to insufficient amount. In the present application, when the atomizer core needs to be replaced, it is only necessary to remove the atomizer core for replacement, which greatly reduces the user's cost of use; at the same time, the aerosol generating matrix outside the accommodation space is introduced into the heating element through the liquid guide, avoiding the defect caused by the storage of all aerosol generating matrix in the atomizer core in the prior art.

[0048] Please refer to Figures 1 to 8 In one embodiment, an atomizer 10 is provided, including a shell 11 and an atomizer core 12.

[0049] The housing 11 has a receiving space 111 and a liquid inlet 112 ; the atomizer core 12 is removably disposed in the receiving space 111 .

[0050] The atomizing core 12 includes a heating element 121 and a liquid guiding element 122. The liquid guiding element 122 connects the liquid inlet 112 and the heating element 121 to deliver the aerosol-generating substrate outside the accommodation space 111 to the heating element 121.

[0051] When the user inhales, the control host 20 supplies power to the atomizer core 12 through a suction action or a button action, and the heating element 121 of the atomizer core 12 works to generate heat to heat the aerosol-generating matrix delivered by the atomizer liquid guide 122, thereby producing aerosol for the user to inhale.

[0052] In the related art, the nebulizer 10 is injected with 2 mL of aerosol generating matrix. When the 2 mL of aerosol generating matrix is ​​consumed, the nebulizer 10 needs to be replaced as a whole. With the iteration of technology, the service life of the liquid guide component 122 and the heating component 121 is continuously extended. Therefore, after the 2 mL of aerosol generating matrix is ​​consumed, the heating component 121 and the liquid guide component 122 are still usable. At this time, replacing the nebulizer 10 as a whole will cause serious waste.

[0053] In addition, stockpiling a large number of atomizers 10 at one time does not conform to the purchasing habits of general consumers, so consumers need to go to stores frequently to buy, resulting in a poor user experience.

[0054] In one embodiment, reference Figure 8 The liquid guide 122 can draw the aerosol-generating substrate outside the nebulizer, so that the amount of aerosol-generating substrate that can be consumed by the nebulizer 10 is much greater than the volume of the nebulizer 10. For example, refer to Fig. 9 When the atomizer 10 in the above embodiment is used in combination with the main unit 20 and the container 30, assuming that the volume of the atomizer 10 is 2 mL and the volume of the container 30 is 30 mL, since the atomizer 10 can draw the aerosol generating substrate from the outside of the atomizer through the liquid guide 122, the actual amount of aerosol generating substrate that can be consumed by the atomizer is 12 mL. This is equivalent to the capacity of 6 atomizers 10 in the related art.

[0055] In addition, the volume of the container 30 is not limited to 10 mL. When the volume of the container 30 is greater than a threshold value (for example, 30 mL), the atomizer core 12 may have reached the end of its service life, but the aerosol generating matrix in the container 30 has not been completely consumed. According to the description of the above embodiment, the atomizer core 12 can be removed relative to the atomizer 10, so that the consumer can choose to replace the atomizer core 12 with a new one, which greatly reduces the user's usage cost and avoids waste of resources.

[0056] At the same time, the aerosol generating matrix outside the accommodating space 111 is introduced into the heating element 121 through the liquid guiding member 122, that is, the aerosol generating matrix is ​​drawn from the container outside the atomization core 12, which is equivalent to appropriately extending the liquid guiding path of the aerosol generating matrix, and can better control the storage amount of the aerosol generating matrix near the heating element 121, thereby avoiding the problem of oversaturation of the aerosol generating matrix and improving the user's smoking taste.

[0057] In addition, since the atomizer 10 of the above embodiment needs to be used in conjunction with a host 20 with a liquid supply portion (for example, the liquid supply portion is a container 30), the atomizer 10 does not need to be pre-injected with an aerosol generating matrix, or only a small amount of aerosol generating matrix is ​​injected, thereby solving the problem of liquid leakage caused by the atomizer 10 during transportation (bumps, changes in altitude, etc.), and can significantly reduce the occurrence of customer complaints.

[0058] In one embodiment, the liquid guiding member 122 includes an atomizing liquid guiding member 1221 connected to the heating member 121 for liquid conduction, and the aerosol generating matrix from outside the accommodating space 111 at the liquid inlet 112 is delivered to the heating member 121 through the atomizing liquid guiding member 1221, and then heated and atomized by the heating member 121.

[0059] In one embodiment, if Figure 2 As shown, the atomizing liquid guide 1221 includes a first liquid guide portion 12211 connected to the heating element 121, and a second liquid guide portion 12212 extending from the first liquid guide portion 12211 to the liquid inlet 112. The aerosol generating matrix from outside the accommodating space 111 at the liquid inlet 112 is delivered to the first liquid guide portion 12211 through the second liquid guide portion 12212, and then heated and atomized by the heating element 121. In this embodiment, the aerosol generating matrix outside the accommodating space 111 is directly accessed through the atomizing liquid guide 1221, which can reduce the aerosol generating matrix retained in the atomizing core 12, making the atomization amount more accurate and improving the user's taste.

[0060] In some embodiments, the second liquid guide portion 12212 and the first liquid guide portion 12211 may have different liquid absorption and liquid storage capabilities. For example, the first liquid guide portion 12211 is made of porous ceramics, and the second liquid guide portion 12212 is made of cotton. The liquid absorption and liquid storage capabilities of cotton are greater than those of porous ceramics, and the service life of ceramics is greater than that of cotton. In addition, cotton can fully supply liquid to ceramics, so that the heating element 121 is not prone to dry burning. Therefore, the overall service life of this atomizer core 12 is better and it is not prone to dry burning.

[0061] In some embodiments, the second liquid guiding portion 12212 has a liquid absorption and storage capacity smaller than that of the first liquid guiding portion 12211. For example, the second liquid guiding portion 12212 is made of porous ceramics, and the first liquid guiding portion is made of cotton. Since the liquid absorption and storage capacity of cotton is greater than that of porous ceramics, the aerosol generating matrix provided by the second liquid guiding portion 12212 is not prone to oversaturation problems. That is, in this atomization core 12, the heating element 121 is not prone to oversaturation of the aerosol generating matrix, resulting in poor smoking taste.

[0062] In some embodiments, the second liquid guiding portion 12212 can protrude from the end surface of the liquid inlet 112, or be flush with the end surface of the liquid inlet 112, or be inside the liquid inlet 112. It is only necessary that the second liquid guiding portion 12212 can be connected to the external liquid guiding portion to introduce the aerosol generating matrix from outside the containing space 111.

[0063] In one embodiment, if Figure 3As shown, the liquid guide member 122 also includes a lower liquid guide member 1222 disposed in the accommodating space 111. The lower liquid guide member 1222 extends to the liquid inlet 112 to access the aerosol generating substrate outside the accommodating space 111. The lower liquid guide member 1222 is connected to the atomizing liquid guide member 1221 for liquid conduction to deliver the aerosol generating substrate to the atomizing liquid guide member 1221, and then the heating element 121 heats and atomizes the substrate to generate an aerosol. In this embodiment, the lower liquid guide member 1222 can be provided to continuously provide the aerosol generating substrate to the heating element 121, which can effectively prevent dry burning.

[0064] In some embodiments, the liquid absorption capacity of the lower liquid guide 1222 and the atomizing liquid guide 1221 may be different, for example, the liquid absorption capacity of the lower liquid guide 1222 is greater than the liquid absorption capacity of the atomizing liquid guide 1221, so that the lower liquid guide 1222 can quickly deliver the aerosol-generating matrix outside the accommodation space 111 to the atomizing liquid guide 1221, and the liquid absorption capacity of the atomizing liquid guide 1221 is lower than that of the lower liquid guide 1222, so that oversaturation can be avoided, thereby avoiding the effect of oversaturation on the taste. It is understandable that the liquid absorption capacity of the lower liquid guide 1222 and the atomizing liquid guide 1221 can be adjusted by changing their material or porosity.

[0065] In one embodiment, if Figure 4 As shown, the liquid guide member 122 also includes an upper liquid guide member 1223 disposed in the receiving space 111. The upper liquid guide member 1223 is connected to the lower liquid guide member 1222 and the atomizing liquid guide member 1221 for liquid conduction. The aerosol generating substrate outside the receiving space 111 is connected through the lower liquid guide member 1222, delivered to the upper liquid guide member 1223, and then delivered to the atomizing liquid guide member 1221, and then heated and atomized by the heating element 121 to generate an aerosol.

[0066] In one embodiment, the upper liquid guide 1223 can be used to pre-inject the aerosol generating matrix to prevent the core from being stuck. The reason is that it takes a certain amount of time (about 20 seconds for general products) for the aerosol generating matrix to be introduced from the container 30 to the heating element 121. If the upper liquid guide 1223 for pre-injecting the aerosol generating matrix is ​​not provided, the user will immediately inhale after loading the atomizer 10 into the host 20. At this time, there is no aerosol generating matrix near the heating element 121, which will cause the core to be stuck. On the one hand, it will damage the user experience, and on the other hand, it will reduce the service life of the atomizer core 12 or directly damage the atomizer core 12.

[0067] In one embodiment, the liquid absorption capacity of the lower liquid guide 1222 is greater than that of the atomizing liquid guide 1221, and the liquid absorption capacity of the atomizing liquid guide 1221 is greater than that of the upper liquid guide 1223. The lower liquid guide 1222 with a greater liquid absorption capacity can quickly deliver the aerosol generating substrate outside the accommodation space 111 to the upper liquid guide 1223; while the upper liquid guide 1223 has a weaker liquid absorption capacity, so it can be used as a storage medium to store the aerosol generating substrate; while the atomizing liquid guide 1221 has a stronger liquid absorption capacity than the upper liquid guide 1223, and after the heating element 121 atomizes the aerosol generating substrate of the atomizing liquid guide 1221, the atomizing liquid guide 1221 can inhale the aerosol generating substrate from the upper liquid guide 1223 for subsequent atomization. This embodiment can not only effectively and quickly replenish the aerosol generating substrate, but also ensure that the aerosol generating substrate in the atomizing liquid guiding member 1221 will not be oversaturated, thereby affecting the taste.

[0068] In one embodiment, the atomizing liquid guide 1221, the lower liquid guide 1222, and the upper liquid guide 1223 may be liquid guide cotton or porous ceramic liquid guides, etc. In some embodiments, the atomizing liquid guide 1221 and the lower liquid guide 1222 may be porous ceramic liquid guides, and the upper liquid guide 1223 may be liquid guide cotton. Of course, in some other embodiments, the atomizing liquid guide 1221, the upper liquid guide 1223, and the lower liquid guide 1222 may be liquid guides made of the same material, or may be liquid guides made of different materials, as required.

[0069] In one embodiment, if Figure 6 As shown, the atomizer core 12 also includes an atomizer core base 123. The heating element 121 and the liquid guide element 122 are installed on the base of the atomizer core 12. The atomizer core base 123 is at least partially exposed outside the shell 11. The user can pull the entire atomizer core 12 out of the shell 11 by operating the exposed part of the atomizer core base 123, thereby realizing the detachable assembly of the atomizer core 12 and the shell 11, which is convenient to operate and easy to replace the atomizer core 12.

[0070] In one embodiment, the end of the housing 11 where the atomizing core 12 is disposed is the lower part, and the end for the user to inhale is the upper part.

[0071] like Figure 6As shown, operating parts 1231 are provided on both sides of the atomizer core base 123, and correspondingly, side wall slots 113 are provided on the lower side walls of the shell 11. When the atomizer core 12 is inserted into the shell 11, the operating part 1231 can be clamped in the side wall slot 113. In some embodiments, the side wall slots 113 can be provided on both sides of the shell 11, and are roughly square in shape. Correspondingly, the operating part 1231 is also square, and is buckled by interference fit, thereby realizing a detachable connection between the atomizer core base 123 and the shell 11. Of course, the shapes of the operating part 1231 and the side wall slot 113 can be designed as needed. In other embodiments, a buckle structure such as a hook or a buckle groove can also be provided between the operating part 1231 and the side wall slot 113, so that the buckle of the two is more stable.

[0072] Furthermore, in order to facilitate the operation of pulling out the atomizer core 12, the operating portion 1231 at least partially protrudes from the outer wall of the housing 11, thereby facilitating the user's operation. In some embodiments, an operating ridge 1232 may also be provided on the outer wall of the operating portion 1231 to increase the contact area and friction, thereby facilitating the user to hold and pull out the atomizer core 12 from the housing 11.

[0073] In one embodiment, if Figure 7 As shown, the atomizer core 12 is provided with an atomization channel 1224, and the generated aerosol can be output through the atomization channel 1224 for the user to inhale. The atomizer core base 123 may include a vent 1233, which is in communication with the atomization channel 1224, so that the outside air can be introduced through the vent 1233, and then enter the atomization channel 1224 to mix with the aerosol and then output. The vent 1233 can cooperate with the air guide column 25 corresponding to the atomizer device to form a closed air passage, which will be described in detail later.

[0074] In one embodiment, if Figure 7 As shown, two conductive blind holes 1234 are provided on the bottom surface of the atomizer core base 123. The ends of the positive and negative electrode leads of the heating element 121 are fixed in the conductive blind holes 1234 respectively. When the atomizer core 12 is inserted into the atomizer device, the electrode 42 is inserted into the conductive blind hole 1234 to contact the ends of the positive and negative electrode leads of the heating element 121, thereby providing working power for the heating element 121. The design of the conductive blind hole 1234 can ensure that the electrical connection between the electrode 42 and the heating element 121 is in a closed space, thereby preventing the aerosol generating matrix from entering the position where the electrode 42 is located, thereby improving the safety of the product.

[0075] In one embodiment, a slot 114 or a bump is provided on the outer side of the side wall of the housing 11. A corresponding bump 34 or a slot is provided on the side wall of the atomizing device or container 30, so that the atomizer 10 and the atomizing device or container 30 are better combined into a whole, which will be described in detail later.

[0076] like Figure 8 As shown, in some embodiments, the shape of the upper liquid guide 1223 matches the shape of the inner cavity of the housing 11, so that it can be fixed in the housing 11 by interference fit. Of course, the upper liquid guide 1223 and the housing 11 can also be fixed by various existing methods, which are not limited here.

[0077] In some embodiments, the upper liquid guide member 1223 is further provided with an installation through hole 12231 for installing the atomization liquid guide member 1221 and the heating element 121 therein, so as to ensure that the aerosol generation matrix is ​​evenly guided to the heating element 121 to improve the atomization effect.

[0078] In one embodiment, the lower liquid guide 1222 is fixedly mounted at the lower end of the housing 11. In addition, the lower liquid guide 1222 is disposed on the outer side of the atomizer core base 123 and isolated from the vent 1233 of the atomizer core base 123, thereby preventing the aerosol-generating matrix from entering the vent 1233 and affecting the suction effect. Of course, the lower liquid guide 1222 can also be fixedly connected to the atomizer liquid guide 1221, or integrally formed with the atomizer liquid guide 1221.

[0079] like Figure 8 As shown, in some embodiments, the lower liquid guide member 1222 is composed of two pieces, which are separately arranged on the outside of the atomizer core base 123. In addition, the inner side of the lower liquid guide member 1222 is arc-shaped, matching the shape of the atomizer core base 123. Through the two-piece design, a space for the atomizer core base 123 to be inserted is formed in the middle, which can facilitate the insertion and removal of the atomizer core 12. It can be understood that the lower liquid guide member 1222 can also be an integrated design or a split design of more pieces to form a space for the atomizer core 12 to be inserted.

[0080] In one embodiment, the end surface of the lower liquid guide 1222 protrudes from the lower end surface of the housing 11. When the atomizer 10 is inserted into the atomizing device, the protruding portion is squeezed to form a tight fit, which is more conducive to the transmission of the aerosol generating matrix, as described in detail below.

[0081] In one embodiment, the atomizer 10 also includes a suction nozzle 13 connected to the shell 11. The suction nozzle 13 is provided with a suction channel 131, which is connected to the atomization channel 1224 of the atomization core 12. When the user inhales, the aerosol can be drawn out through the atomization channel 1224 and the suction channel 131. The shell 11 and the suction nozzle 13 can be a split structure. After the components are assembled, the two are combined into a whole, which improves the convenience of assembly. It can be understood that the shell 11 and the suction nozzle 13 can also be an integrated design, and the internal components can be installed in sequence, which can reduce the number of parts and assembly steps.

[0082] In one embodiment, the atomizer 10 may further include a liquid absorbing member 14 and an upper sealing member 15. A ventilation channel is provided in the liquid absorbing member 14 and the upper sealing member 15, which is connected to the atomization channel 1224 and the suction channel 131. The liquid absorbing member 14 is arranged on a side close to the suction channel 131, and is used to absorb the liquid condensed by the aerosol. The upper sealing member 15 is arranged between the liquid absorbing member 14 and the liquid guiding member 122, so as to avoid the liquid absorbed by the liquid absorbing member 14 from being transmitted to the liquid guiding member 122, thereby ensuring the purity of the aerosol generating matrix. The upper sealing member 15 may be a sealing member made of a silicone member or other materials.

[0083] In one embodiment, a seal 115 is provided on the lower outer wall of the housing 11. When the atomizer 10 is inserted into the atomizer device, the seal 115 can be used to seal the gap between the outer wall of the housing 11 and the inner wall of the atomizer device, thereby preventing leakage of the aerosol-generating matrix and ensuring that there is no liquid leakage. The seal 115 can be a silicone seal ring, or of course, a seal made of other materials.

[0084] In one embodiment, a protrusion 116 may be provided on the outer side of the housing 11. Correspondingly, a groove (not shown) may be provided on the inner wall of the cavity of the atomizer. When the atomizer 10 is inserted, the atomizer 10 may be positioned by the cooperation of the protrusion 116 and the groove, forming a detachable fixed cooperation structure.

[0085] In one embodiment, the atomizer 10 may further include a protective cover 16. The protective cover 16 may be sleeved on the lower portion of the housing 11 to close the lower opening of the housing 11 to prevent the atomizer core 12, the liquid guide 122, etc. from being exposed, thereby preventing the atomizer 10 from being contaminated before use.

[0086] Please refer to Figures 9 to 11 In one embodiment, an atomization device is provided, which mainly includes a host 20, a container 30, and an atomizer 10 of any of the above embodiments.

[0087] The container 30 can be integrally formed with the host 20 or detachably mounted on the host 20, and is used to output the aerosol generating matrix to the atomizer 10. The atomizer 10 is detachably connected to the host 20, and is used to heat and atomize the aerosol generating matrix from the container 30 to generate an aerosol for the user to inhale.

[0088] When the atomizer core 12 of the atomizer 10 reaches the end of its service life, or is about to reach the end of its service life, or needs to be replaced in other situations, the user can pull the atomizer 10 out of the host 20, and then disassemble and separate the atomizer core 12 from the shell 11 of the atomizer 10 for replacement, and then insert the atomizer 10 after the replacement of the atomizer core 12 into the host 20 for reuse, thereby greatly reducing the user's use cost and avoiding waste of resources. At the same time, the aerosol generating matrix of the container 30 is introduced into the heating element 121 through the liquid guide 122 of the atomizer core 12, avoiding the defect of storing all aerosol generating matrix in the atomizer core 12 in the prior art.

[0089] In one embodiment, the atomizing device further comprises a liquid infusion structure 21 for connecting the outlet 31 of the container 30 with the liquid infusion member 122 of the atomizer 10. The aerosol generating substrate in the container 30 is delivered to the liquid infusion member 122 of the atomizing core 12 via the liquid infusion structure 21.

[0090] In one embodiment, the infusion structure 21 includes an infusion member 212. The infusion member 212 is disposed at the outlet 31 of the container 30, and the infusion member 212 is connected to the infusion member 122 of the atomizer 10. After the container 30 is assembled to the host 20, the aerosol-generating substrate is output from the outlet 31 of the container 30, and is adsorbed by the end of the infusion member 212 corresponding to the container 30, and is transmitted to the end of the atomizer core 12.

[0091] In one embodiment, the infusion piece 212 is made of cotton and has a sheet-like structure. The infusion piece 212 is arranged in a direction perpendicular to the length of the host 20. One end of the infusion piece 212 covers the outlet 31 of the container 30, and the other end conducts liquid to connect to the liquid guide piece 122.

[0092] In one embodiment, the host 20 includes a first cavity 22 and a second cavity 23 arranged side by side. The nebulizer 10 is removably arranged in the first cavity 22, and the container 30 is arranged in the second cavity 23. The first cavity 22 and the second cavity 23 are connected through the infusion structure 21. By arranging two cavities side by side, the nebulizer 10 and the container 30 can be arranged separately, which can better avoid mixing of gas and liquid.

[0093] In one embodiment, the container 30 is detachably connected to the host 20. The container 30 and the host 20 may also be provided with a buckle structure for buckling the two. Figure 6 As shown, in some embodiments, the buckle structure includes a buckle hole 33 provided on the side wall of the container 30, and a barb (not shown) provided on the inner wall of the cavity of the host 20. After the container 30 is inserted, the container 30 is fixed in the cavity of the host 20 by the cooperation between the barb and the buckle hole 33. It can be understood that the buckle hole 33 can also be provided on the inner wall of the cavity of the host 20, and the barb can be provided on the side wall of the container 30.

[0094] In one embodiment, in order to better position the atomizer 10, a concave-convex structure for positioning the atomizer 10 and the host 20 may be provided between the atomizer 10 and the host 20. In some embodiments, the concave-convex structure may include a circular protrusion 116 provided on the outer wall of the housing 11 of the atomizer 10, and a groove (not shown) provided on the inner wall of the first cavity 22 of the host 20. It is understandable that in another embodiment, the concave-convex structure may include a circular groove provided on the outer wall of the housing 11 of the atomizer 10, and a protrusion provided on the inner wall of the first cavity 22 of the host 20. After the atomizer 10 is inserted into the first cavity 22, the protrusion 116 is snapped into the groove, so that the position of the atomizer 10 in the host 20 can be better positioned.

[0095] In one embodiment, a first sealing structure may be provided between the container 30 and the host 20. The first sealing structure may be a sealing member provided between the outlet 31 of the container 30 and the inner wall of the second cavity 23 of the host 20, thereby further improving the sealing performance and preventing the aerosol-generating matrix from leaking from the gap between the container 30 and the second cavity 23. It is understandable that the sealing member may be an independent silicone sealing member, or a sealing member formed by adding a protrusion to the outer wall of the sealing member of the container 30; of course, it may also be a sealing structure of any other structure.

[0096] In one embodiment, a second sealing structure may be provided between the atomizer 10 and the host 20. Fig.10 As shown, the second sealing structure can be a sealing member 115 disposed on the outer wall of the housing 11 of the atomizer 10. The sealing member 115 can be a silicone sealing ring or a sealing ring made of other materials. After the atomizer 10 is inserted into the first cavity 22, the sealing member 115 seals the gap between the outer wall of the atomizer 10 and the inner wall of the first cavity 22, thereby playing a sealing role and preventing the aerosol-generating matrix from leaking out from the gap between the two.

[0097] In one embodiment, a buckle structure may be provided between the atomizer 10 and the container 30. The atomizer 10 and the container 30 are buckled together by the buckle structure, so that the two can form a more stable whole, making the entire atomizing device more beautiful; moreover, a more stable structure can further improve its performance in preventing liquid leakage.

[0098] In one embodiment, the buckle structure includes a slot 114 provided on the outer side of the side wall of the housing 11 of the atomizer 10, and a protrusion 34 provided on the side wall of the container 30 to be slidably buckled with the slot 114. In another embodiment, the buckle structure may also include a protrusion provided on the outer side of the side wall of the housing 11 of the atomizer 10, and a slot provided on the side wall of the container 30 to be slidably buckled with the protrusion. The atomizer 10 and the container 30 may be slidably buckled by the sliding cooperation between the protrusion 34 and the slot 114.

[0099] In one embodiment, the liquid outlet direction of the container 30 is parallel to and opposite to the airflow direction of the atomizer 10. Fig.10 As shown, the liquid flows in the direction of arrow A. The outlet 31 of the container 30 is downwardly disposed, and the liquid is discharged in a downward direction. The aerosol-generating matrix flows to the infusion structure 21 under the action of gravity, and is then transmitted to the liquid guide 122 through the infusion structure 21.

[0100] like Fig.11 As shown, the airflow direction is as shown by arrow B, and the airflow direction of the atomizer 10 is upward. When inhaling, the airflow enters from the suction port of the main unit 20, passes through the atomization core 12 of the atomizer 10, and brings out the aerosol for the user to inhale. By setting the liquid outlet channel and the airflow channel separately, the interference between the two is avoided, which not only ensures the sealing of the aerosol generation matrix, but also ensures the independence of the airflow, thereby improving the safety and experience of the entire device.

[0101] In one embodiment, the infusion structure 21 of the host 20 further includes a conducting member 211, which is used to open the outlet 31 of the container 30 to form a liquid outlet channel to output the aerosol generating substrate. The infusion member 212 is arranged downstream of the liquid outlet channel and intersects with the liquid outlet direction, and is used to transfer the aerosol generating substrate to the liquid guiding member 122. Fig.10 As shown, the liquid outlet channel is vertically arranged, and the infusion piece 212 is horizontally arranged; it can be understood that the arrangement angle and direction thereof can be adjusted as needed.

[0102] In some embodiments, the container 30 may also be provided with a leak-proof component. The leak-proof component may include an outlet seal 32 provided with a slot. The conducting member 211 squeezes the outlet seal 32 of the aerosol generating container 30 so that the aerosol generating matrix cannot form a sealing oil film at the slot, thereby opening the liquid outlet channel of the container 30. The conducting member 211 may be a hollow liquid guide tube, such as a steel pipe. In some embodiments, the leak-proof component includes a sealing film, and the conducting member 211 may be a puncturing structure, which punctures the sealing film through the puncturing structure, thereby opening the liquid outlet channel. The puncturing structure may be a syringe structure containing a liquid guide hole, or may be a rod-shaped structure composed of an oil guide material or an oil guide structure.

[0103] When the container 30 and the host 20 are assembled together, the liquid outlet channel of the container 30 can be connected through the conductive member 211, which can effectively prevent oil leakage during the assembly process and improve the convenience of use.

[0104] In one embodiment, the lower liquid guiding member 1222 partially protrudes from the liquid inlet 112 of the shell 11. After the nebulizer 10 is inserted and installed in the host 20, the protruding portion contacts the infusion member 212. Since the end face of the lower liquid guiding member 1222 protrudes from the lower end face of the shell 11, the protruding portion is squeezed, so that the infusion member 212 and the lower liquid guiding member 1222 are tightly joined, which is more conducive to the transmission of the aerosol generating matrix.

[0105] In one embodiment, the atomization device further includes a battery assembly 40 , through which the battery assembly 40 provides working power for the atomization core 12 of the atomizer 10 .

[0106] In one embodiment, the battery assembly 40 may include a battery 41 and two electrodes 42 connected to the positive and negative electrodes of the battery 41. After the atomizer 10 is inserted into the host 20, the electrode 42 is inserted into the corresponding conductive blind hole 1234 of the atomizer 10. The electrode 42 contacts the positive and negative electrodes of the heating element 121, thereby providing working power to the heating element 121. The design of the conductive blind hole 1234 can ensure that the electrical connection between the electrode 42 and the heating element 121 is in a closed space, thereby preventing the aerosol generating matrix from entering the position where the electrode 42 is located, thereby improving the safety of the product.

[0107] In one embodiment, the host 20 may also be provided with an air guide column 25. The air guide column 25 corresponds to the position of the vent hole 1233 of the atomizer core base 123. After the atomizer 10 is inserted into the atomizer device, the air guide column 25 is inserted into the atomizer core base 123 and connected to the vent hole 1233, thereby forming a closed air passage.

[0108] Correspondingly, an air inlet 26 may be provided on the mainframe 20, and the air inlet 26 is in communication with the air guide column 25. Of course, the air inlet 26 may be provided on the bottom surface, side surface or other suitable position of the mainframe 20.

[0109] During inhalation, the airflow enters the main unit 20 from the air inlet 26, then enters the air vent 1233 of the atomizer core base 123 through the air guide column 25, and then enters the atomization channel 1224 of the atomizer core 12, bringing out the aerosol generated by the heating element 121 and entering the nozzle 13. Fig.11 In the direction indicated by the arrow in B.

[0110] In some embodiments, the host 20 of the atomizing device may further include an airflow sensor, etc. Of course, a power supply component, a bracket for installing the infusion component 212, etc. may also be provided in the host 20, which will not be elaborated here.

[0111] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For technicians in the technical field to which the present application belongs, they can also make some simple deductions, deformations or substitutions based on the ideas of the present application.
