[0064] Figure 1 The first embodiment of the electronic atomizing device of this utility model is shown. This electronic atomizing device can be used to atomize a medium, especially a liquid medium, to generate an aerosol.

[0067] like Figures 8 to 10 As shown, in this embodiment, the electronic atomizing device includes a liquid storage shell 11. Further, the liquid storage assembly 10 may include the liquid storage shell 11. The liquid storage shell 11 is used to store the medium to be atomized. The liquid storage shell 11 may include a housing 11a and an air passage tube 11b. The housing 11a has a hollow structure, with one end forming a nozzle end 114 and the other end an open end 112.

In some embodiments, the base 121 may be an injection molded part, and the sealing element 122 may be a silicone part or a rubber part; the base 121 and the sealing element 122 may be formed into an integral structure by in-mold injection molding. By forming the base 121 and the sealing element 122 into an integral structural component by in-mold injection molding, sealing failure caused by the flange of the sealing element 122 during assembly can be prevented. In some embodiments, the base 121 is not limited to being an injection molded part, but may be a ceramic part or a metal part; the base 121 and the sealing element 122 are not limited to being formed into an integral structural component by in-mold injection molding, but may also be formed into an integral structural component by casting. In some other embodiments, the base 121 and the sealing element 122 may be separate structures, which may be fixed by nesting. In some embodiments, the seal 122 may be omitted, and the sealing seat 12 may only include the base 121. In some embodiments, the base 121 may be a silicone or rubber component, which may be a structural component that serves both a connecting and sealing function.

[0071] In this embodiment, the base 121 may include a main body 121a and a connecting part 121b. The cross-sectional shape and size of the main body 121a may be adapted to the cross-sectional shape and size of the opening end 112.

It is understood that in some other embodiments, the through hole 1211 is not limited to a circular through hole, and can be a square hole, an ellipse, or an irregular shape (partially convex or concave). Each through hole 1211 has a first limiting groove 1210 on its end face facing the suction nozzle end 114. The first limiting groove 1210 can be used to limit the seal 122. In some other embodiments, the first limiting groove 1210 can be omitted.

[0073] In this embodiment, the base 121 is provided with a mounting hole 1212, which can be used for assembly with the seal 122 and / or the airway tube 11b. Specifically, the mounting hole 1212 can be provided in the main body 121a of the base 121, and coaxially arranged with the airway tube 11b. The mounting hole 1212 can be provided between two through holes 1211. When the base 121 is installed at the open end 112, the airway tube 11b can be partially inserted into the mounting hole 1212.

In some other embodiments, when the seal 122 is omitted, the airway tube 11b and the mounting hole 1212 can be fixed by an interference fit. Of course, it is understandable that in some other embodiments, the airway tube 11b and the mounting hole 1212 can also be connected and fixed by providing a connection structure.

[0074] In this embodiment, a second limiting groove 1213 is provided on the base 121. The second limiting groove 1213 can be provided on the side wall of the main body 121a and extends circumferentially along the main body 121a. The second limiting groove 1213 can cooperate with the sealing member 122 for limiting.

[0075] In this embodiment, a limiting platform 1214 is provided on the base 121. The limiting platform 1214 is disposed on the side of the main body 121a. There can be two limiting platforms 1214, which are disposed along the long axis of the base 121 and protrude along the long axis from the edge of the main body 121a away from the nozzle end 114. The limiting platform 1214 can be used to limit the top cover 14. In some other embodiments, the limiting platform 1214 is not limited to two; there can be one or more (e.g., three or four). In some embodiments, the limiting platform 1214 can be omitted.

[0076] In this embodiment, there may be two connecting portions 121b, which are spaced apart along the long axis of the main body 121a. In some embodiments, the connecting portion 121b may be a hook that can engage with the atomizing component 20. The two hooks are arranged opposite to each other. Of course, it is understood that in some other embodiments, the connecting portion 121b may not be limited to a hook, but may also be a connector with a snap hole. In some other embodiments, the connecting portion 121b may not be limited to two, but may be one or more. In some embodiments, the connecting portion 121b may not be limited to a snap-fit ​​structure, but may be a threaded connection structure.

[0077] In this embodiment, the sealing element 122 can be nested with the base 121. In this second embodiment, the sealing element 122 may include a first sealing portion 122a. The first sealing portion 122a may be correspondingly disposed with the through hole 1211. In this embodiment, there are two first sealing portions 122a, and the two first sealing portions 122a are correspondingly disposed with the two through holes 1211. When the sealing element 122 is assembled with the base 121, the first sealing portion 122a is at least partially embedded in the through hole 1211. Specifically, the first sealing portion 122a may be partially placed in the through hole 1211 and tightly fitted with the through hole 1211, specifically, the first sealing portion 122a may be interference-fitted with the through hole 1211. In this embodiment, the first sealing portion 122a may be a hollow structure with both ends through. In this embodiment, the first sealing portion 122a may be cylindrical.

[0078] In this embodiment, the sealing seat 12 is provided with a mating channel 1221, which is at least partially formed in the sealing member 122 and / or the base 121. In this embodiment, the mating channel 1221 is at least partially formed in the first sealing portion 122a, and the mating channel 1221 can be used to mate with the atomizing assembly 20. There can be two mating channels 1221, which are spaced apart. The mating channel 1221 has a channel opening 1223 facing the liquid storage chamber 111. A sealing rib 1224 is provided on the end face of the channel opening 1223. The sealing rib 1224 can protrude from the end face of the channel opening 1223 and can be arranged circumferentially along the channel opening 1223. The sealing rib 1224 can be generally annular. The sealing rib 1224 can be at least one; in this embodiment, there can be two sealing ribs 1224. Of course, it is understood that in other embodiments, the sealing rib 1224 is not limited to two. In other embodiments, the sealing rib 1224 can be omitted. The first sealing part 122a has a limiting flange 1220 at one end of the mating channel 1221. The limiting flange 1220 can cooperate with the first limiting groove 1210 to limit the sealing part, thereby preventing the first sealing part 122a from dislodging from the through hole 1211. In some embodiments, the limiting flange 1220 can be omitted.

[0079] In this embodiment, the sealing element 122 further includes a second sealing portion 122b, which is disposed on the outer periphery of the first sealing portion 122a and connected to the first sealing portion 122a. When the sealing element 122 is assembled with the base 121, the second sealing portion 122b can be sleeved on the outer periphery of the base 121. In this embodiment, the second sealing portion 122b can be annular and can be sleeved on the second limiting groove 1213. The end wall of one end of the second sealing portion 122b can be connected to the limiting flange 1220 of the first sealing portion 122a. In this embodiment, the second sealing portion 122b and the first sealing portion 122a are an integral structure; specifically, the second sealing portion 122b and the first sealing portion 122a can be integrally formed by injection molding. The sealing seat 12 can achieve sealing through the close contact between the second sealing portion 122b and the inner wall of the top cover 14 or the inner wall of the liquid storage shell 11.

[0080] In this embodiment, the seal 122 further includes a third sealing portion 122c, which can be disposed between two first sealing portions 122a. The two oppositely disposed sidewalls of the third sealing portion 122c can be connected to two second sealing portions 122b. The third sealing portion 122c, the second sealing portions 122b, and the first sealing portions 122a can be integrally formed by injection molding. The third sealing portion 122c can be correspondingly disposed in the mounting hole 1212 and can be embedded in the mounting hole 1212. The third sealing portion 122c is a hollow structure with both ends open. The shape and size of the third sealing portion 122c can be adapted to the mounting hole 1212. An insertion hole 1222 can be formed on the inner side of the third sealing portion 122c. The third sealing portion 122c can be tightly fitted with the mounting hole 1212 and the air passage 11b.

[0081] For example Figures 8 to 10 As shown, in this embodiment, each mating channel 1221 has a partition structure 13. In a first state, the partition structure 13 can isolate the mating channel 1221 from the liquid storage chamber 111. The partition structure 13 can switch from the first state to a second state. When the partition structure 13 is in the second state, the medium to be atomized in the liquid storage chamber 111 can be output to the atomizing assembly 20. By setting the partition structure 13, leakage of the medium to be atomized in the liquid storage chamber 111 can be prevented when the liquid storage assembly 10 and the atomizing assembly 20 are not assembled. After the liquid storage assembly 10 and the atomizing assembly 20 are mated, switching from the first state to the second state allows the liquid storage chamber 111 and the atomizing assembly 20 to communicate, ensuring smooth liquid supply from the liquid storage chamber 111 to the atomizing assembly 20.

[0082] In this embodiment, the partition structure 13 is disposed at the channel opening 1223 along the direction of transversely cutting the mating channel 1221 to form a first state. Specifically, the partition structure 13 may cover the channel opening 1223, thereby isolating the mating channel 1221 from the liquid storage chamber 111. In some other embodiments, the partition structure 13 may not be limited to being disposed at the channel opening 1223 of the mating channel 1221. In some embodiments, the partition structure 13 may be configured to isolate the mating channel 1221 in the first state, in which case the partition structure 13 can divide the mating channel 1221 into two non-connected parts.

[0083] In this embodiment, the partition structure 13 is axially movable within the mating channel 1221. The partition structure 13 can switch states through movement. When the partition structure 13 moves away from the channel opening 1223 until a gap h is left between it and the channel opening 1223, a second state is formed, at which point both ends of the mating channel 1221 are connected. In this embodiment, the gap h can be greater than zero, and can be specifically determined based on the available space for the partition structure 13 to move. In this embodiment, the partition structure 13 can move under the push of an external force. In some embodiments, the partition structure 13 can also be reset under the action of elasticity. In other embodiments, the partition structure 13 is not limited to a movable configuration; it can also be fixedly installed in the mating channel 1221 or at the channel opening 1223 of the mating channel 1221. The partition structure 13 can be broken or deformed to form the second state.

[0084] In this embodiment, the partition structure 13 may include a partition member 131, which is movably disposed in the axial direction of the mating channel 1221. In this embodiment, the partition member 131 may include a partition portion 1311, which may be plate-shaped. The cross-sectional shape of the partition portion 1311 may be adapted to the cross-sectional shape of the channel opening 1223. In this embodiment, the partition portion 1311 has a partition body 1313 and a limiting stop 1314. The partition body 1313 may be generally circular, and its cross-sectional dimension may be larger than the cross-sectional dimension of the channel opening 1223. For example, the outer diameter of the partition body 1313 may be larger than the outer diameter of the channel opening 1223, thereby covering the channel opening 1223. In the first state, the partition structure 13 is sealed to the sealing member 122. Specifically, in the first state, the partition body 1313 may abut against the sealing rib 1224, thereby sealing the connection between the two. In some embodiments, the partition body 1313 may also be pressed against the end face where the channel opening 1223 is located, and a seal is achieved through close contact with the end face. A limiting stop 1314 protrudes from at least one side of the partition body 1313. In this embodiment, there may be two limiting stops 1314, positioned on opposite sides of the partition body 1313. By providing the limiting stops 1314, interference with other components can be generated, thereby limiting the overall movement distance of the partition 131. In other embodiments, there may be one, two, three, or four limiting stops 1314. In some embodiments, the limiting stops 1314 may be omitted.

[0085] In this embodiment, the partition 131 may further include a columnar body 1312. The columnar body 1312 is disposed at the central axis of the partition portion 1311, and may extend through the partition portion 1311 along its thickness direction. The columnar body 1312 can be used to strengthen the partition portion 1311 and also to guide its movement. In this embodiment, the columnar body 1312 may be cylindrical. In other embodiments, the columnar body 1312 may not be limited to a cylindrical shape and may be a square column. In this embodiment, the columnar body 1312 may be integrally formed with the partition portion 1311. Specifically, the columnar body 1312 and the partition portion 1311 may be integrally formed by injection molding. It is understood that in other embodiments, the columnar body 1312 may be omitted.

[0086] The partition structure 13 may also include an elastic element 132. The elastic element 132 is disposed on the partition 131 and abuts against the partition, which allows the partition 131 to move more smoothly and facilitates the repositioning of the partition 131. In this embodiment, the elastic element 132 can be a spring, which can be sleeved on the columnar body 1312, with one end tightly abutting against the partition portion 1311. In some other embodiments, the elastic element 132 can be omitted, and the partition 131 can maintain a gap h between itself and the channel opening 1223 after the atomizing assembly 20 is mated with the liquid storage assembly 10.

[0087] In this embodiment, there can be two partition structures 13, and the two partition structures 13 can be configured one-to-one with the two mating channels 1221. That is, the number of partition structures 13 can be configured to correspond to the number of mating channels 1221. In some embodiments, the number of partition structures 13 may not correspond to the number of mating channels 1221. The partition structure 13 is not limited to two; it can be one. Multiple mating channels 1221 can share one partition structure 13. For example, two mating channels 1221 can share one partition structure 13. In this embodiment, the partition portion 1311 of the partition structure 13 covers the channel openings 1223 of the multiple mating channels 1221.

[0088] See also Figures 8 to 10 as well as Figures 14 to 15 In this embodiment, the electronic atomizing device further includes a top cover 14. More specifically, the liquid storage assembly 10 includes a top cover 14, which is fitted onto the sealing seat 12 and partially disposed within the liquid storage shell 11. The inner wall of the top cover 14 contacts the outer wall of the sealing element 122 of the sealing seat 12, and the two are sealed together, thereby preventing leakage of the atomized medium. In this embodiment, a partition structure 13 is disposed within the top cover 14.

[0089] In this embodiment, the top cover 14 may include an outer sleeve 14a and an inner sleeve 14b. The outer sleeve 14a is fitted around the outer periphery of the sealing seat 12, and its inner sidewall abuts against the outer sidewall of the sealing member 122 of the sealing seat 12 to achieve a seal. The inner sleeve 14b is disposed in the insertion hole 1222 into which the sealing member 122 can be partially inserted, and it is in close contact with the inner wall of the insertion hole 1222 of the sealing member 122 to achieve a seal. The inner sleeve 14b may be fitted around the outer periphery of a portion of the air passage 11b. The inner sleeve 14b has a through-hole structure at both ends, and a through hole 141 may be defined on the inner side of the inner conductor 14b.

[0090] In this embodiment, the top cover 14 further includes a cover body 14c, which is disposed on the end of the outer cover 14a facing the nozzle end 114, and is disposed on and connected to the outer cover 14a and the inner cover 14b. The cover body 14c is integrally formed with the outer cover 14a and the inner cover 14b. Specifically, the cover body 14c is integrally formed with the outer cover 14a and the inner cover 14b by injection molding. In this embodiment, the cover body 14c is correspondingly disposed with the mating channel 1221. Specifically, there can be two cover bodies 14c, and the two cover bodies 14c can be correspondingly disposed with the two mating channels 1221 one by one. In some other embodiments, when there is only one mating channel 1221, there can be only one cover body 14c.

[0091] The cover 14c can be cylindrical, specifically, it can be hollow. In this embodiment, the top cover 14 also has a first liquid outlet channel 140, which can be formed between the cover 14c, the outer cover 14a, and the inner cover 14b, and can communicate with the liquid storage cavity 111. Specifically, the first liquid outlet channel 140 can extend from the side of the cover 14c to the bottom of the cover 14c. When the partition structure 13 is in the first state, the first liquid outlet channel 140 is isolated from the mating channel 1221. When the partition structure 13 is switched to the second state, the first liquid outlet channel 140 communicates with the gap h.

[0092] In this embodiment, the top cover 14 has a baffle 142 disposed opposite to the mating channel 1221. Specifically, the baffle 142 is formed at one end of the cover 14c that is opposite to the mating channel 1221. The baffle 142 is disposed between the mating channel 1221 and the liquid storage chamber 111, and is disposed opposite to the mating channel 1221. The elastic member 132 of the partition structure 13 can abut against the partition member 131 and the baffle 142. Specifically, one end of the elastic member 132 can abut against the partition member 131, and the other end can abut against the baffle 142, so that the partition member 131 can move and reset under the elastic force of the elastic member 132.

[0093] In this embodiment, a guide post 143 may be provided in the cover 14c. The guide post 143 is located at the central axis of the cover 14c, and one end can be connected to the baffle 142. The guide post 143 has a hollow structure, which allows the cylindrical body 1312, which is fitted with an elastic element 132, to be inserted. By providing the guide post 143, it is ensured that the partition 131 can move axially along the mating channel 1221, and the partition 131 is prevented from shifting.

[0094] In this embodiment, a limiting boss 144 is provided at one end of the outer casing 14a. The limiting boss 144 can be provided at the end of the outer casing 14a away from the cover 14c. The limiting boss 144 is provided circumferentially along the outer casing 14a and can protrude from the outer peripheral wall of the outer casing 14a for cooperating with the liquid storage shell 11 for limiting. When the liquid storage shell 11 is sleeved on the top cover 14, the end face of the opening end 112 of the liquid storage shell 11 can rest on the limiting boss 144. In some embodiments, the limiting boss 144 can be omitted.

[0095] In this embodiment, the inner wall of the outer sleeve 14a is provided with a first inner limiting step 145 and a second inner limiting step 146. The first inner limiting step 145 and the second inner limiting step 146 are spaced apart axially from each other on the outer sleeve 14a, with the first inner limiting step 145 located near the limiting protrusion 144 and the second inner limiting step 146 located near the cover 14c. Both the first inner limiting step 145 and the second inner limiting step 146 are used to cooperate with the sealing seat 12 for limiting, thereby restricting the assembly position of the sealing seat 12 and the top cover 14. Specifically, when the top cover 14 and the sealing seat 12 are assembled, the outer sleeve 14a is fitted onto the outer periphery of the sealing element 122 of the sealing seat 12, and the first inner limiting step 145 can cooperate with the limiting platform 1214 of the sealing seat 12 for limiting, with the first inner limiting step 145 resting on the limiting platform 1214. The second inner limiting step 146 can be pressed against the end face of the sealing seat 12 facing the nozzle end 114. In some embodiments, the first inner limiting step 145 and / or the second inner limiting step 146 can be omitted.

[0096] In this embodiment, an outer limiting step 147 may be provided on the outer side wall of the outer casing 14a. In this embodiment, the outer limiting step 147 is correspondingly provided on the outside of the second inner limiting step 146, and it can be used to limit the sealing structure 15. In some other embodiments, the outer limiting step 147 may be omitted.

[0097] like Figure 10 as well as Figure 16As shown, in this embodiment, a sealing structure 15 is provided between the top cover 14 and the liquid storage shell 11. The sealing structure 15 can be sleeved on the outer periphery of the outer sleeve 14a of the top cover 14, and the sealing structure 15 can be limited by the outer limiting step 147. In this embodiment, the sealing structure 15 can be fixed with the top cover 14 by an interference fit. The outer wall of the sealing structure 15 can abut against the inner wall of the liquid storage shell 11 to form a seal. In some other embodiments, the sealing structure 15 may be omitted.

[0098] In this embodiment, the sealing structure 15 is an elastic sealant; specifically, the sealing structure 15 can be a silicone or rubber component. The sealing structure 15 includes an embedding portion 151 and a sleeve portion 152. The embedding portion 151 is partially embedded in the through hole 141, contacting the inner wall of the through hole 141 and forming a seal. The embedding portion 151 has a through hole 1511 for inserting the air passage tube 11b. The inner wall of the through hole 1511 contacts the outer wall of the air passage tube 11b, achieving a tight seal. The sleeve portion 152 is disposed on the outer periphery of the embedding portion 151, fitting around the outer periphery of the top cover 14 and achieving a seal through an interference fit. The outer wall of the sleeve portion 152 contacts the inner wall of the liquid reservoir 11, forming a seal. In this embodiment, the insert portion 151 can be connected to the sleeve portion 152, and the two can be integrally formed. Specifically, the insert portion 151 and the sleeve portion 152 can be formed into an integral structure through injection molding.

[0099] In this embodiment, a clearance hole 1512 is provided between the insert portion 151 and the sleeve portion 152, and the clearance hole 1512 can be provided one-to-one with the cover body 14c. The clearance hole 1512 can be used to allow the cover body 14c to pass through.

[0100] In this embodiment, the sealing structure 15 is provided with a second liquid outlet channel 153, which is formed in the relief hole 1512. Generally, a gap can be left between the relief hole 1512 and the cover 14c, and this gap can form the second liquid outlet channel 153. The second liquid outlet channel 153 can communicate with the liquid storage chamber 111 and the first liquid outlet channel 140. The medium to be atomized in the liquid storage chamber 111 can be discharged to the atomizing assembly 20 from the second liquid outlet channel 153, the first liquid outlet channel 140, and the gap h.

[0101] In this embodiment, the liquid storage assembly 10 can seal the gap between the top cover 14 and the liquid storage shell 11 by providing a sealing structure 15. Specifically, it can seal the gap between the inner wall of the shell 11a and the outer wall of the top cover 14, and the gap between the air passage 11b and the through hole 141. The inner wall of the top cover 14 can contact and seal with the outer wall of the sealing seat 12. Specifically, the gap between the top cover 14 and the sealing seat 12 can be sealed by the sealing element 122 of the sealing seat 12. When the liquid storage assembly 10 is not connected to the atomizing assembly 20, the sealing element 122 on the sealing seat 12 can form a seal with the partition structure 13. By providing the above structure, the risk of leakage of the liquid storage assembly 10 when it is not connected to the atomizing assembly 20 can be greatly reduced, thereby improving the user experience.

[0102] In this embodiment, the liquid storage assembly 10 may further include a bottom cover 16, which can be sleeved on one end of the liquid storage shell 11 having an open end 112, and the bottom cover 16 can be snapped and fixed to the liquid storage shell 11. In some embodiments, a snap hole 161 may be provided on the side wall of the bottom cover 16, and a snap buckle 115 may be provided on the outer side wall of the liquid storage shell 11. When the bottom cover 16 and the liquid storage shell 11 are assembled, the snap buckle 115 can be snapped into the snap hole 161. A through hole 162 is provided on the bottom wall of the bottom cover 16, which can be used for the connecting part 121b of the sealing seat 12 to pass through, so that the sealing seat 12 can be mated with the atomizing assembly 20.

[0103] In this embodiment, the bottom cover 16 can be a metal cover, such as an aluminum cover, an iron cover, or a stainless steel cover. In some embodiments, the bottom cover 16 can also be omitted.

[0104] like Figures 17 to 18 As shown, in this embodiment, the atomizing assembly 20 may include an atomizing seat 21 and an atomizing structure 22. The atomizing seat 21 can be mated with the sealing seat 12, thereby communicating with the liquid storage chamber 111 for liquid guidance and with the air passage 11b for air guidance. In this embodiment, the atomizing seat 21 can be mated with the sealing seat 12 by snap-fit. In some other embodiments, the atomizing seat 21 can also be mated with the sealing seat 12 by interference fit or threaded connection. The atomizing structure 22 can be housed in the atomizing seat 21 and is used to atomize the medium to be atomized delivered from the liquid storage chamber 111. In this embodiment, the atomizing structure 22 has an atomizing surface 221, which is approximately parallel to the liquid guidance direction.

[0105] In this embodiment, the atomizing base 21 includes a first base 21a and a second base 21b. The first base 21a is used to mate with the sealing base 12, and the first base 21a can be installed on the second base 21b. The second base 21b can be used to support the atomizing structure 22.

[0106] like Figures 20 to 21As shown, in this embodiment, the first seat 21a may include a first body 211. The first body 211 may be connected to the sealing seat 12. The first body 211 may be disposed at one end of the second seat 21b. In this embodiment, the first body 211 may include a mating portion 211a and a limiting portion 211b. The mating portion 211a may be used to mate with the sealing seat 12. The limiting portion 211b may be disposed on at least one side of the mating portion 211a and is stepped with the mating portion 211a, and may be used to limit the installation of the first seat 21a. In this embodiment, there may be two limiting portions 211b, which are disposed on two opposite sides of the mating portion 211a. The mating portion 211a has a long axis and a short axis, and the two limiting portions 211b may be disposed in the direction of the long axis of the mating portion 211a. In some embodiments, the limiting portion 211b may be omitted.

[0107] In this embodiment, a fixing hole 2111 is provided on the first body 211. A magnetic element 210 can be provided inside the fixing hole 2111. The fixing hole 2111 can be provided on the end wall of the first body 211, that is, on the end wall of the mating part 211a. There can be at least one fixing hole 2111. In this embodiment, there can be two fixing holes 2111. The two fixing holes 2111 can be provided at intervals. In some other embodiments, the fixing holes 2111 are not limited to two, but can be three, four, five, etc.

[0108] In this embodiment, a locking protrusion 2112 may be provided on the first seat 21a. This locking protrusion 2112 may be provided on two opposite sidewalls of the first seat 21a. Specifically, there may be two locking protrusions 2112, which may be located along the long axis of the mating portion 211a. The locking protrusions 2112 are not limited to being located along the long axis of the mating portion 211a. The locking protrusions 2112 can be correspondingly provided with the connecting portion 121b. In this embodiment, each locking protrusion 2112 may be correspondingly provided with one connecting portion 121b. When the first seat 21a mates with the sealing seat 12, the connecting portion 121b can engage with the locking protrusion 2112. Both the connecting portion 121b and the locking protrusion 2112 are oblique snap-fit ​​structures, making them detachably connected, thus facilitating the easy assembly and disassembly of the liquid storage component 10 and the atomizing component 20.

[0109] In this embodiment, the atomizing seat 21 has a protruding liquid guiding structure 212. This liquid guiding structure 212 is movable relative to and can engage with the mating channel 1221. The liquid guiding structure 212 can be inserted into one of the mating channels 1221 and engage with that channel. In this embodiment, the liquid guiding structure 212 can be disposed on the first seat 21a. Specifically, the liquid guiding structure 212 can protrude from the mating portion 211a and protrude from the end wall of the mating portion 211a. The liquid guiding structure 212 is a hollow columnar structure with both ends connected. In this embodiment, the liquid guiding structure 212 can be integrally formed with the mating portion 211a. In this embodiment, the liquid guiding structure 212 and the mating portion 211a can be formed as an integral structure through injection molding or casting. Of course, it is understandable that the liquid guiding structure 212 and the mating part 211a can also be detachable separate structures, and the two can be fixed by inserting a clip or by interference fit.

[0110] In this embodiment, the liquid guiding structure 212 has a liquid guiding channel 2121, specifically, the liquid guiding channel 2121 is formed in the liquid guiding structure 212. The liquid guiding structure 212 is provided with a liquid inlet 2122, specifically, the liquid inlet 2122 may be provided on the side wall of the liquid guiding structure 212. In some other embodiments, the liquid guiding structure 212 is not limited to being located at the liquid inlet 2122; the liquid inlet 2122 may be located at one end of the liquid guiding structure 212 facing the mating channel 1221. The liquid inlet 2122 may communicate with the liquid guiding channel 2121.

[0111] In this embodiment, when the sealing seat 12 is mated with the atomizing seat 21, the liquid guiding structure 212 can penetrate into the mating channel 1221 and drive the partition structure 13 to switch from the first state to the second state, so that the liquid storage chamber 111 and the liquid guiding channel 2121 are connected, so that the atomizing medium in the liquid storage chamber 111 can flow into the liquid guiding channel 2121 in a direction approximately parallel to the moving direction of the liquid guiding structure 212, that is, the atomizing medium in the liquid storage chamber 111 can flow into the liquid guiding structure 212 in a vertical direction.

[0112] In this embodiment, when the liquid guiding structure 212 penetrates the mating channel 1221, it can drive the partition structure 13 to move. This allows the partition structure 13 to move away from the channel opening 1223, creating a gap h between the partition structure 13 and the channel opening 1223. This means the partition structure 13 switches to a second state, and when it does, the liquid guiding channel 2121 and the liquid storage chamber 111 are connected through this gap h. Specifically, the liquid guiding structure 212 can contact the partition member 131 of the partition structure 13. During the mating process between the atomizing seat 21 and the sealing seat 12, the liquid guiding structure 212 can push the partition member 131 towards the baffle 142. The partition member 131 can move under the action of the elastic member 132. This gap h can communicate with the first liquid outlet channel 140, and the liquid guiding channel 2121 of the liquid guiding structure 212 can communicate with the gap h via the liquid inlet 2122.

[0113] In some other embodiments, the liquid guiding structure 212 may not be limited to switching the partition structure 13 from the first state to the second state by moving the partition structure 13. In some other embodiments, the liquid guiding structure 212 may cause the partition structure 13 to break or deform, thereby switching the partition structure 13 from the first state to the second state.

[0114] In this embodiment, an air guide column 213 is provided on the atomizing base 21. Specifically, the air guide column 213 is disposed on the first base body 21a, located at the central axis of the mating part 211a, and extending along the thickness direction of the mating part 211a. The air guide column 213 is a hollow structure with both ends open. An air guide channel 2131 can be formed inside the air guide column 213, which can be used to guide the aerosol generated after atomization to the air outlet channel 113. In this embodiment, the cross-sectional shape and size of the air guide column 213 can be adapted to the cross-sectional shape and size of the air passage 11b.

[0115] In this embodiment, during the mating process between the atomizing seat 21 and the sealing seat 12, the air guide column 213 passes through the mounting hole 1212 and the insertion hole 1222 in sequence, and passes through the through hole 141. It is coaxially arranged with the airway tube 11b and communicates with the airway tube 11b.

[0116] In this embodiment, the first seat 21a further includes an extension 214, which is disposed on at least one side of the mating portion 211a and extends in a direction opposite to the mating direction between the mating portion 211a and the sealing seat 12. The extension 214 can be used to connect with the second seat 21b. In this embodiment, the mating portion 211a has extensions 214 on both opposite sides in the minor axis direction. In this embodiment, the extension 214 can be snapped into and fixed to the second seat 21b. In this embodiment, a snap-fit ​​hole 2141 may be provided on the extension 214. In some other embodiments, a snap-fit ​​buckle may be provided on the extension 214.

[0117] In some other embodiments, the extension 214 may not be limited to being snapped into the second seat 21b. In other embodiments, the extension 214 may be threadedly connected to the second seat 21b, the extension 214 may be provided with a first connecting through hole, the second seat 21b may be provided with a second connecting through hole, and the extension 214 and the second seat 21b may be connected by a screw thread, which may pass through the first connecting through hole to the second connecting through hole.

[0118] like Figure 18 , Figures 22 to 23 As shown, in this embodiment, the second seat 21b and the first seat 21a are detachably assembled. In some other embodiments, the second seat 21b and the first seat 21a may also be an integral structure. In some embodiments, the second seat 21b and the first seat 21a may be injection molded as an integral part.

[0119] In this embodiment, the inner side of the second seat 21b is hollow, and the inner side of the second seat 21b can define a cavity 215. The cavity 215 can be connected to the liquid guiding channel 2121. The liquid guiding channel 2121 can introduce the medium to be atomized into the cavity 215. The medium to be atomized can be atomized in the cavity 215 to generate an aerosol. The aerosol can be output through the gas guiding channel 2131.

[0120] In this embodiment, the second seat 21b includes a receiving portion 216 and a connecting and fixing portion 217. The receiving portion 216 can be used to receive the atomizing structure 22. The receiving portion 216 is generally cylindrical, and a cavity 215 can be formed in the receiving portion 216. The connecting and fixing portion 217 is disposed at one end of the receiving portion 216 and is used to connect with the first seat 21b.

[0121] In this embodiment, the receiving portion 216 may include a first sidewall 2160, two second sidewalls 2161, and a third sidewall 2162. In this embodiment, the first sidewall 2160 may be disposed between the two second sidewalls 2161 and may be in contact with the two second sidewalls 2161. The third sidewall 2162 is disposed opposite to the first sidewall 2160, between the two second sidewalls 2161, and in contact with the two second sidewalls 2161. In this embodiment, the first sidewall 2160 may be a curved structure. The second sidewalls 2161 and the third sidewall 2162 may both be planar structures. It is understood that in some other embodiments, the receiving portion 216 may not be limited to including the aforementioned sidewalls. The cavity 215 may be defined by the first sidewall 2160, the two second sidewalls 2161, and the third sidewall 2162.

[0122] In this embodiment, a receiving cavity 2163 may be provided on the third sidewall 2162, which can be used to receive the atomizing structure 22. A connecting hole 2164 may be provided between the receiving cavity 2163 and the cavity body 215. In this embodiment, by providing the receiving cavity 2163 on one side of the cavity body 215, the atomizing structure 22 can form lateral atomization, which facilitates the natural upward floating of the atomized aerosol and avoids the problem of air bubble trapping.

[0123] In this embodiment, a snap-fit ​​member 2165 is provided on the outer wall surface of the second sidewall 2161, which can be used to snap and fix the third seat 21c. In this embodiment, the snap-fit ​​member 2165 can protrude from the second sidewall 2161. And each second sidewall 2161 can be provided with at least one snap-fit ​​member 2165.

[0124] In this embodiment, a liquid guide 2166 is provided in the accommodating part 216. The liquid guide 2166 can be located at the bottom end of the cavity 215. It can be inclined from the first side wall 2160 toward the connecting hole 2164. Specifically, it can be connected to the side of the connecting hole 2164 away from the connecting fixing part 217, and can be used to guide the atomized medium in the cavity 215 to the atomizing structure 22.

[0125] In this embodiment, the atomizing seat 21b has a liquid storage and ventilation structure 2167. This structure is disposed on the side opposite to the liquid guide 2166 and the cavity 215, and is communicative to the cavity 215 for ventilation. In this embodiment, the liquid storage and ventilation structure 2167 may be columnar, with an open end away from the liquid guide 2166 and a hollow interior. An inner cavity 2168 is defined, which is communicative to the cavity 215. Microgrooves 2169 may be provided on the inner wall of the liquid storage and ventilation structure 2167, and these microgrooves are communicative to the cavity 215. These microgrooves 2169 may be capillary grooves, which can be used for ventilation. In some embodiments, condensate generated during atomization can be drawn in through capillary action. It should be noted that, since the atomizing component 20 is connected to the power supply component 30, especially when it is installed inside the power supply component 30, the microgroove 2169 can prevent excessive condensate from overflowing into the power supply component 30 and causing it to malfunction. In this embodiment, the microgroove 2169 can be arranged along the axial direction of the liquid storage and ventilation structure 2167 and can be located close to the first sidewall 2160.

[0126] In this embodiment, the cross-sectional dimensions of the microgroove 2169 can be 0.05*0.1mm, where 0.05 represents the width of the microgroove 2169 and 0.1mm represents its depth. It should be noted that since the atomized medium in this application is an aqueous medium (mainly water) with very low viscosity, an excessively large cross-sectional dimension of the microgroove 2169 could easily lead to leakage. Therefore, by setting the aforementioned dimensions, both ventilation and condensate adsorption can be ensured, preventing leakage of the atomized medium.

[0127] In this embodiment, the cross-sectional shape and size of the connecting and fixing part 217 can be adapted to the cross-sectional shape and size of the first base 21a. In this embodiment, the transverse interface of the connecting and fixing part 217 can be approximately elliptical, and the connecting and fixing part 217 can extend partially from the third sidewall 2162 away from the third sidewall 2162. An insertion interface 2170 can be provided on the connecting and fixing part 217, which can communicate with the cavity 215 for partial insertion of the liquid guiding structure 212. A fixing buckle 2171 can be provided on the sidewall of the connecting and fixing part 217, which can be matched with the snap-fit ​​hole 2141 on the extension part 214 and can snap into the snap-fit ​​hole 2141.

In some embodiments, the plug-in part 218 can be provided at the central axis of the connecting fixing part 217, and the central axis of the plug-in part 218 can be parallel to and spaced apart from the third side wall 2162, and can be located on the outside of the third side wall 2162. In this embodiment, the inner side of the plug-in part 218 is hollow and has a through-end structure. The cross-sectional shape and size of the plug-in part 218 can be adapted to the cross-sectional shape and size of the air guide column 213.

[0129] like Figure 18 , Figure 19 as well as Figure 24 As shown, in this embodiment, the atomizing seat 21 further includes a third seat 21c. The third seat 21c is detachably assembled with the second seat 21b and can be disposed on the side of the third sidewall 2162 of the second seat 21b away from the first sidewall 2160. The third seat 21c can be used to form an airway structure. In some embodiments, the third seat 21c and the second seat 21b can be an integral structure, and the third seat 21c and the second seat 21b can be integrally formed by injection molding.

[0130] In this embodiment, the third seat 21c may include a connecting seat 219a and a supporting base 219b. The connecting seat 219a is disposed on the supporting base 219b and can be installed on one side of the third sidewall 2162. The supporting base 219b can be used to support the second seat 21b. In this embodiment, the connecting seat 219a and the supporting base 219b can be an integrally formed structure. Specifically, the connecting seat 219a and the supporting base 219b can be integrally formed by injection molding or casting.

[0131] In this embodiment, the connecting seat 219a may include an outer peripheral wall 2191 and a partition wall 2192. The outer peripheral wall 2191 is arranged to form a semi-elliptical columnar structure. In other embodiments, the outer peripheral wall 2191 is not limited to forming a semi-elliptical columnar structure; the columnar structure it forms may also be semi-cylindrical or semi-square. The partition wall 2192 may be disposed in the outer peripheral wall 2191, dividing the internal space of the outer peripheral wall 2191 into a first chamber 2193 and a second chamber 2190, which are arranged in parallel. The first chamber 2193 is open at the end away from the supporting base 219b. The second chamber 2190 is open on both the side facing the third sidewall 2162 and the side facing the connecting fixing part 217. The second chamber 2190 between the partition wall 2192 and the third side wall 2162 can form an atomizing airway, which can be connected to the air guide column 213. The atomizing structure 22 can be arranged toward the atomizing airway, and the aerosol generated by the atomization of the atomizing structure 22 can be output from the atomizing airway, the air guide column 213, and the air outlet channel 113.

[0132] In this embodiment, the outer peripheral wall 2191 has two opposite sides with snap-fit ​​portions 2194 extending toward the second sidewall 2161. Snap-fit ​​portions 2194 can be snapped onto snap-fit ​​members 2165 disposed on the second sidewall 2161 of the second seat 21b. In this embodiment, the snap-fit ​​portion 2194 has a snap-fit ​​through hole 2195, which can be correspondingly disposed with the snap-fit ​​member 2165. When the second seat 21b and the third seat 21c are assembled, the snap-fit ​​member 2165 can be snapped into the snap-fit ​​through hole 2185.

[0133] In this embodiment, when the third seat 21c is assembled with the second seat 21b, the support base 219b can be arranged parallel to the connecting fixing part 217. The receiving part 216 of the second seat 21b is inserted into the support base 219b.

[0134] In this embodiment, an air inlet column 2196 is provided in the support base 219b. This air inlet column 2196 allows external gas to enter the second chamber 2190 and carries out the aerosol generated after the atomization of the atomized medium. In this embodiment, multiple air inlet holes 2197 can be provided on the air inlet column 2196. These air inlet holes 2197 can be micropores, allowing gas to enter. The condensate shell forms a liquid film at the air inlet holes 2197. By providing multiple air inlet holes 2197, gas can be allowed to enter while preventing condensate leakage. An accommodating groove 2198 can be defined on the inner side of the support base 219b. This accommodating groove 2198 can be used for the insertion of the second seat 21b, and a gap can be left between it and the liquid storage and ventilation structure 2167. This gap can communicate with the air inlet holes 2197 and the micro-groove 2169 to form a ventilation channel.

[0135] In this embodiment, a limiting installation groove 2199 may be provided on the outer side wall of the support base 219b. The limiting installation groove 2199 may extend circumferentially along the support base 219b for the installation of the sealing member 26.

[0136] In this embodiment, the third seat 21c is provided with a first connection through hole 21c1. In this embodiment, the first connection through hole 21c1 can be provided on the side wall of the support base 219b, which can be used for the connection component 40 to pass through, thereby facilitating the connection and fixation of the third seat 21c and the power supply component 30. In some embodiments, the first connection through hole 21c1 can be omitted.

[0137] In this embodiment, the atomizing base 21 further includes a magnetic cover 21d, which can be placed on the second base 21b. Specifically, it can be sleeved on the connecting fixing part 217 and can be attracted to the magnetic element 210 in the first base 21a, thereby connecting the first base 21a to the second base 21b. The magnetic cover 21d can be provided with a first mounting through hole 21d1 and a second mounting through hole 21d2. The first mounting through hole 21d1 can be correspondingly provided with the liquid guiding structure 212. The first mounting through hole 21d1 allows the liquid guiding structure 212 to pass through for installation. The second mounting through hole 21d2 can be correspondingly provided with the air guiding column 213. The second mounting through hole 21d2 allows the air guiding column 213 to pass through for installation. A notch 21d3 may be provided on the side wall of the magnetic cover 21d. The notch 21d3 may be provided in correspondence with the fixing buckle 2171, allowing the fixing buckle 2171 to pass through so that the fixing buckle 2171 can be connected to the first base 21a.

[0138] In some other embodiments, the atomizing seat 21 is not limited to the structure described above. The atomizing seat 21 can be designed according to actual needs. The atomizing seat 21 can be any structure that is mated with the atomizing seat 12 of the liquid storage component 10 and has a liquid guiding structure 212.

[0139] In this embodiment, the atomizing structure 22 can be selected as an ultrasonic atomizing plate, which is more suitable for water-containing media to be atomized. This ultrasonic atomizing plate can generate aerosols through vibration, making it suitable for smoke-free environments.

[0140] In other embodiments, when the atomizing medium is not limited to an aqueous atomizing medium, the atomizing structure 22 can be selected as a resistance heating structure, an electromagnetic heating structure, a light wave heating structure, a microwave heating structure, etc.

[0141] In this embodiment, the atomizing structure 22 can be disposed on one side of the cavity 215, with its atomizing surface 221 facing the cavity 215 and approximately parallel to the liquid guiding direction of the cavity 215. The atomizing structure 22 can employ a lateral atomization method. When the atomizing structure 22 is working, the aerosol generated by atomization naturally rises and is output from the atomizing air channel, greatly reducing the risk of air bubble blockage causing the atomizing structure 22 to fail and improving atomization quality. Furthermore, the approximately parallel alignment of the atomizing structure 22 with the liquid guiding direction makes liquid guiding smoother, maximizing the contact area between the atomizing structure 22 and the liquid within a given cavity 215 size. In this embodiment, since the atomizing surface 221 is laterally disposed, only one liquid guiding channel needs to be provided on one side of the atomizing surface 221, further saving space and simplifying the layout of the atomizer. Of course, in other embodiments, multiple liquid guiding channels can be provided on the atomizing base.

[0142] In some other embodiments, when the atomizing structure 22 is not limited to an ultrasonic atomizing sheet, the atomizing structure 22 may be disposed at the center of the cavity 215 or on the outer periphery of the cavity 215, and it may not be limited to atomizing in the direction of lateral atomization.

[0143] In this embodiment, the atomizing component 20 further includes a conductive structure 23, which can be connected to the atomizing structure 22 and the power supply component 30, thereby enabling the power supply component 30 to supply power to the atomizing structure 22. In this embodiment, there can be two conductive structures 23, which can be spaced apart.

[0144] In this embodiment, the conductive structure 23 can be a push pin, the side of which can contact and conduct with the atomizing structure 22. By using a push pin, it is not necessary to screen print pads on the surface of the atomizing structure 22 and solder the conductive structure 23 to the pads, thereby reducing the assembly process and saving assembly costs.

[0145] In this embodiment, an annular seal 24 may be provided on the side of the atomizing structure 22 facing the cavity 215. This annular seal 24 can be pressed against the wall surface where the connecting hole 2164 is located, sealing the gap between the wall surface where the connecting hole 2164 is located and the atomizing structure 22. In some embodiments, the annular seal 24 has a central through hole 241, which communicates with both the connecting hole 2164 and the atomizing structure 22. The annular seal 24 can be a silicone or rubber component.

[0146] In this embodiment, the atomizing component 20 further includes a liquid-absorbing structure 25, which can be disposed in the liquid storage and ventilation structure 2167 and can be located in the cavity 2168. The liquid-absorbing structure 25 can be columnar and can be tightly fitted with the liquid storage and ventilation structure 2167. In some embodiments, the liquid-absorbing structure 25 can be fixed to the liquid storage and ventilation structure 2167 by an interference fit. The liquid-absorbing structure 25 can be a porous structure, such as absorbent cotton. In some other embodiments, the liquid-absorbing structure 25 can also be porous ceramic. In some other embodiments, the liquid-absorbing structure 25 can be omitted.

[0147] In this embodiment, the atomizing assembly 20 further includes a sealing member 26, which can be a sealing ring or a sealing sleeve. It can be fitted onto the third seat 21c, specifically, it can be fitted onto the limiting mounting groove 2199, and is installed and limited by the limiting mounting groove 2199. When the atomizing assembly 20 is assembled with the power supply assembly 30, the sealing member 26 can seal the gap between them. The sealing member 26 can be a silicone or rubber component. In some other embodiments, the sealing member 26 can be omitted.

[0148] In this embodiment, the atomizing component 20 is housed in the power supply component 30 and can form a body component with the power supply component 30. That is, the atomizing component 20 and the power supply component 30 can form a whole. The liquid storage component 10 is set separately from the body component, which makes it convenient to replace the liquid storage component 10 and realize the reuse of the atomizing component 20 and multiple atomizations, thereby extending the life of the atomizing component 20, reducing the cost of use, and increasing the assembly efficiency.

[0149] In some other embodiments, the atomizing component 20 and the power supply component 30 can also be separate structures. When an electronic atomizing device is required, the atomizing component 20 and the power supply component 30 can be assembled first, and then assembled with the liquid storage component 10. In some embodiments, the atomizing component 20 and the liquid storage component 10 can also be connected to form a whole, and then connected to the power supply component 30.

[0150] In this embodiment, the power supply assembly 30 includes a housing 31. The housing 31 is generally hollow and cylindrical, and is longitudinally elongated. One end of the housing 31 is provided with an assembly port 311, and the other end is provided with a supporting bottom wall 312. The assembly port 311 is used for inserting the atomizing assembly 20 and the liquid storage assembly 10. The inner side of the housing 31 defines an accommodating space 313. In this embodiment, a second connection through hole 314 is provided on the side wall of the housing 31.

[0151] In this embodiment, the power supply assembly 30 further includes a bracket 32, which is disposed within the housing 31. The bracket 32 ​​supports the atomizing assembly 20 and provides mounting space for the power supply 33 and the electronic control board 34. The bracket 32 ​​can be connected to the atomizing assembly 20. Specifically, the third seat 21c of the atomizing assembly 20 can be sleeved on the bracket 32 ​​and located at the end of the bracket 32 ​​facing the mounting opening 311. The bracket 32 ​​can be provided with mounting holes 321, which can correspond to and communicate with the second connecting through hole 314. In some embodiments, the mounting holes 321 can be threaded holes.

[0152] In this embodiment, the power supply assembly 30 further includes a power supply 33, an electronic control board 34, and a start switch 35. The power supply 33, electronic control board 34, and start switch 35 can all be mounted on the bracket 32. The power supply 33 is connected to the electronic control board 34, and the start switch 35 can be connected to the power supply 33. In some embodiments, the start switch 35 can be an airflow sensing switch, such as a microphone. When the user inhales, the start switch 35 senses the airflow during inhalation and turns on the power supply 33, allowing the power supply 33 to supply power to the atomizing structure 22. The electronic control board 34 is connected to the atomizing structure 22.

[0153] In this embodiment, the power supply component 30 is rechargeable and has a charging structure 36. The charging structure 36 is disposed on the supporting bottom wall 312 and connected to the electronic control board 34, thereby charging the power supply 33. In some other embodiments, the charging structure 36 may be omitted.

[0154] In this embodiment, the electronic atomizing device further includes a connecting component 40, which can be used to connect and fix the power supply component 30 and the atomizing component 20, so that the power supply component 30 and the atomizing component 20 can be connected to form a whole. In this embodiment, the connecting component 40 may include a screw, which may be a screw or a bolt. In some embodiments, the screw may pass through the second connecting through hole 314 and the first connecting through hole 21c1 and enter the mounting hole 321, and be screwed and fixed to the mounting hole 321. In this embodiment, there may be at least two sets of connecting components 40, with at least two corresponding second connecting through holes 314, first connecting through holes 21c1, and mounting holes 321. By setting the connecting component 40, the power supply component 30 and the atomizing component 20 can be detachably connected, which facilitates the replacement of the atomizing component 20, prevents the power supply component 30 and the atomizing component 20 from being scrapped at the same time, and reduces the cost of use.

[0155] In some other embodiments, the connecting component 40 may not be limited to a screw connector; it may also be a magnetic connector or a snap-fit ​​connector. In some other embodiments, the connecting component 40 may be omitted.

[0156] Figures 25 to 30 A second embodiment of the electronic atomizing device of this utility model is shown, which differs from the first embodiment in that the partition structure 13 can be configured with a perforation to form a second state. In this embodiment, the partition structure 13 and the sealing element 122 are integral structural components. Specifically, the partition structure 13 and the sealing element 122 can be integrally molded, and the two can be integrally molded by injection molding. In this embodiment, the partition structure 13 can be a diaphragm formed in the mating channel 1221.

[0157] In some other embodiments, the partition structure 13 can also be deformed to form a second state. In this embodiment, the partition structure 13 can be a deformable valve structure formed in the mating channel 1221.

[0158] In this embodiment, the end of the liquid guiding structure 212 facing the mating channel 1221 is a pointed tip. By making this pointed tip, it is advantageous for the liquid guiding structure 212 to pierce the partition structure 13. In this embodiment, the liquid inlet 2122 is located at the pointed tip of the liquid guiding structure 212. A liquid guiding groove 2123 can be provided on the inner wall of the liquid guiding channel 2121. Multiple liquid guiding grooves 2123 can be provided, spaced circumferentially along the liquid guiding channel 2121. Each liquid guiding groove 2123 extends axially from the liquid inlet 2122 along the liquid guiding channel 2121. In this embodiment, the liquid guiding groove 2123 can be a capillary groove, which can adsorb the medium to be atomized through capillary force.

[0159] In this embodiment, the liquid supply is achieved by directly piercing the partition structure 13 through the liquid guiding structure 212, which has better leak-proof performance, fewer components, and lower manufacturing cost.

[0160] Figures 31 to 35 The third embodiment of the electronic atomizing device of this utility model is shown, which differs from the first embodiment in that:

[0161] The air passage 11b of the liquid storage shell 11 is not coaxial with the shell 11a, that is, the suction nozzle end 114 is not coaxial with the shell 11a, and it can be located on one side of the central axis of the shell 11a. There can be one mating channel 1221. The third seat 21c can be integrally formed with the bracket 32.

[0162] In this embodiment, a pushing mechanism 2124 is provided in the liquid guiding channel 2121. This pushing mechanism 2124 can be used to push the partition structure 13 to switch states, that is, to push the partition structure 13 to move and switch the partition structure 13 from a first state to a second state. In this embodiment, the liquid guiding channel 2121 can be formed between the pushing mechanism 2124 and the liquid guiding structure 212. When the sealing seat 12 is mated with the atomizing seat 21, the liquid guiding structure 212 can penetrate into the mating channel 1221. The pushing mechanism 2124 can move towards the partition structure 13 under the action of external force and contact the partition structure 13. It can push the partition structure 13 against the baffle 142, thereby leaving a gap h between the partition member 131 of the partition structure 13 and the channel opening 1223. The liquid guiding channel 2121 can communicate with the gap h, and the medium to be atomized in the liquid storage chamber 111 can flow into the liquid guiding channel 2121 from the gap h.

[0163] In this embodiment, the pushing mechanism 2124 can push the partition structure 13 under the action of elastic force. In this embodiment, the pushing mechanism 2124 may include a push rod 212a and an elastic structure 212b. The push rod 212a can be arranged along the axial direction of the liquid guiding channel 212, and it can be coaxially arranged with the liquid guiding channel 212. The push rod 212a can extend from one end of the liquid guiding channel 212, and it can contact the partition structure 13 to push the partition structure 13. The elastic structure 212b can be sleeved on the push rod 212a so that the push rod 212a can move under the action of elastic force.

[0164] In this embodiment, the push rod 212a may include a push rod body 2125, a pushing part 2126, and a limiting protrusion 2127. The push rod body 2125 may be cylindrical and may extend axially along the liquid guiding channel 2121. The pushing part 2126 may be disposed at one end of the push rod body 2125 facing the partition structure 13, and the cross-sectional dimension of the pushing part 2126 may be smaller than the cross-sectional dimension of the push rod body 2125. In this embodiment, the end of the push rod body 2125 connected to the pushing part 2126 may be concave toward the pushing part 2126. The cross-sectional shape and size of the push rod body 2125 may be adapted to the cross-sectional shape and size of the liquid inlet 2122. In some embodiments, the limiting protrusion 2127 may be disposed on the push rod body 2125, and is disposed near the end of the push rod body 2125 away from the partition structure 13. The limiting protrusion 2127 can be extended circumferentially along the push rod body 2125, and can be limited by the first seat 21a.

[0165] In this embodiment, the elastic structure 212b is sleeved on the push rod body 2125. It can be disposed on the side of the limiting protrusion 2127 away from the pushing part 2125, and can abut against the limiting protrusion 2127.

[0166] In this embodiment, the pushing mechanism 2124 further includes a fixing seat 212d, which is disposed in the atomizing seat 21. Specifically, it can be disposed in the first seat body 21a and at one end of the liquid guiding channel 2121. It can be fixedly connected to the first seat body 21a by snap-fit ​​or interference fit. The fixing seat 212d can be used to install the elastic structure 212b. The elastic structure 212b can be partially disposed in the fixing seat 212d. One end of the elastic structure 212b can abut against the limiting protrusion 2127, and the other end can abut against the bottom wall of the fixing seat 212d.

[0167] In this embodiment, a sealing connector 212c is fitted onto the push rod body 2125. This sealing connector 212c is positioned close to the push part 2126. In this embodiment, when the atomizing seat 21 and the sealing seat 12 are not properly engaged, i.e., when the connecting part 121b and the locking protrusion 2112 are not engaged, the end of the push rod body 2125 that connects to the push part 2126 can be located at the liquid inlet 2122. The sealing connector 212c can then be in close contact with the inner wall of the liquid inlet 2122 to seal the gap between the liquid inlet 2122 and the push rod body 2125. In this embodiment, the sealing connector 212c can be a sealing ring.

[0168] In this embodiment, before the atomizing component 20 is mated with the liquid storage component 10, the elastic element 132 in the liquid storage component 10 is in an uncompressed state. The partition element 131 seals the liquid storage component 10 through its rebound force and the sealing end face of the sealing seat 12, thereby preventing leakage of the liquid storage component 10. In the atomizing component 20, the elastic structure 212b is fixed on the fixing seat 212d and is in an uncompressed state. At this time, the sealing connector 212c on the push rod body 2125 is located at the liquid inlet 2122 to seal the liquid guiding channel 2121, preventing the residual atomizing medium and / or the condensate formed by condensation in the atomizing component 20 from leaking out from the liquid guiding channel 2121.

[0169] During the mating process between the atomizing component 20 and the liquid storage component 10, before the pushing part 2126 contacts the partition 131, the connecting part 121b and the latching protrusion 2112 are not engaged. The liquid guiding structure 212 and the inner wall of the sealing seat 12 are in close contact to achieve a seal, thereby preventing the atomizing medium from leaking out between the liquid guiding structure 212 and the inner wall of the sealing seat 12 when the pushing part 2126 pushes open the partition 131 during the mating process.

[0170] The atomizing component 20 and the liquid storage component 10 are connected in place, and the connecting part 121b is engaged with the locking protrusion 2112. At the same time, the pushing rod body 2125 contacts the partition 131. Under the action of the elastic structure 212b, the partition 131 is pushed to move towards the baffle 142. At this time, both the elastic element 132 and the elastic structure 212b are in a compressed state, and the liquid guiding channel 2121 is connected to the liquid storage chamber 111.

It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model.
