[0010] In some embodiments, the electronic atomizing device further includes an oil guide, which is installed within the second transverse flow channel.

[0011] In some embodiments, there are two first vertical channels, which are respectively connected to opposite sides of the first transverse channel; the extension direction of the first transverse channel is perpendicular to the extension direction of the second transverse channel.

[0012] In some embodiments, the seal is spherical, and the two ends of the limiting groove have a first opening and a second opening, respectively. The limiting groove is connected to the receiving cavity and the first vertical flow channel through the first opening and the second opening, respectively. The diameter of the seal is greater than the inner diameter of the first opening or the inner diameter of the second opening.

[0013] In some embodiments, the limiting groove includes a constricted end and a flared end connected to each other, the first opening is located on the side of the flared end opposite to the constricted end, and the second opening is located on the side of the constricted end opposite to the flared end; the inner diameter of the first opening is larger than the inner diameter of the seal, the blocking member is disposed on the side of the flared end opposite to the constricted end, and the distance between the blocking member and the first opening is smaller than the diameter of the seal.

[0014] In some embodiments, the oil tank assembly includes a tank body and a connecting component. The tank body is detachably installed on the connecting component. The tank body has the receiving cavity. The connecting component is installed on the main body. The sealing element and the blocking element are both installed on the connecting component.

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0024] The following detailed description, in conjunction with all the accompanying drawings, describes an electronic atomizing device 100 provided in this application through specific embodiments.

[0025] Please refer to Figure 1 Figure 5 One embodiment of this utility model discloses an electronic atomizing device 100, including a main body 10, an atomizing component 20, and an oil tank component 30; the atomizing component 20 is installed on the main body 10, and the atomizing component 20 has an atomizing chamber 202; the oil tank component 30 is installed on the main body 10, and the oil tank component 30 has a receiving cavity 302, a limiting groove 304, and a connecting channel 306, and the receiving cavity 302, the limiting groove 304, the connecting channel 306, and the atomizing component 20 are connected in sequence; the oil tank component 30 includes a sealing member 31 and a blocking member 32, the sealing member 31 is located between the groove wall of the limiting groove 304 and the blocking member 32, and is partially located within the limiting groove 304; the sealing member 31 can open or close the limiting groove 304.

[0026] When the blocking member 32 is below the sealing member 31, the sealing member 31 abuts against the blocking member 32, and the sealing member 31 opens the limiting groove 304. The receiving cavity 302 is connected to the atomizing cavity 202 in sequence through the limiting groove 304 and the connecting channel 306. When the blocking member 32 is above the sealing member 31, the sealing member 31 seals the connection between the limiting groove 304 and the connecting channel 306, and the sealing member 31 closes the limiting groove 304.

[0027] With the above structure, the receiving cavity 302 can store e-liquid; when the sealing member 31 opens the limiting groove 304, when the user is inhaling the electronic atomizing device 100, the user holds the electronic atomizing device 100, the electronic atomizing device 100 is tilted relative to the horizontal plane, the mouthpiece of the electronic atomizing device 100 faces downward, and the blocking member 32 is located below the sealing member 31, thereby connecting the receiving cavity 302 with the atomizing cavity 202; during the process of the user inhaling the electronic atomizing device 100, after the e-liquid in the atomizing component 20 is atomized, the e-liquid in the receiving cavity 302 can flow sequentially through the limiting groove 304 and the connecting channel 306 into the atomizing component 20 for the user to continuously inhale.

[0028] When the user is not inhaling the electronic atomizing device 100, the limiting groove 304 can be closed by the sealing member 31, and the electronic atomizing device 100 can be left to stand still, so that the blocking member 32 is located above the sealing member 31. The sealing member 31 seals the connection between the limiting groove 304 and the connecting channel 306, so that the e-liquid in the receiving cavity 302 will not continue to enter the atomizing component 20, thereby avoiding excessive e-liquid leakage in the atomizing component 20, or leakage of e-liquid through the gap between the oil tank component 30 and the main body 10.

[0029] Specifically, in this embodiment, the main body 10 can be in the form of a block structure similar to a cuboid. The main body 10 can include a shell and a power supply component. The power supply component is installed inside the shell. The shell can also have an air intake chamber, which is connected to the atomizing chamber 202. The user can inhale the smoke in the atomizing chamber 202 through the air intake chamber.

[0030] The atomizing component 20 can be installed inside the outer shell of the main body 10 and located on one side of the shell. The atomizing component 20 typically includes a heating element and a porous wicking body. The porous wicking body transports e-liquid to the heating element, which heats the e-liquid. After atomization, the e-liquid mixes with air in the atomization chamber 202 to form an aerosol. The heating element can be a metallic heating element, such as nickel, chromium, aluminum, iron, or their alloys, and its shape is not limited to heating wire or heating mesh. It can also be a non-metallic heating element, such as carbon fiber or graphite heating elements. The porous wicking body can be made of fibrous materials, such as cotton, linen, or non-woven fabric, or it can be an inorganic non-metallic material such as porous ceramics.

[0031] The main body 10 may also have an oil storage cavity 102, which can be arranged around the atomizing component 20. The oil storage cavity 102 is used to store a portion of the e-liquid. A porous oil guide body communicates with the oil storage cavity 102 to absorb the e-liquid from the oil storage cavity 102 and transfer the e-liquid to the heating element for heating and atomization. In other embodiments, an oil storage cotton is also provided in the oil storage cavity 102. The oil storage cotton stores e-liquid and is in contact with the porous oil guide body to provide e-liquid.

[0032] The oil tank assembly 30 can have a hollow structure similar to a cuboid. The oil tank assembly 30 can be fixed inside the main body 10 or can be detachably installed on the main body. The hollow part of the oil tank assembly 30 forms a receiving cavity 302, which can be filled with liquid e-liquid. The connecting channel 306 can pass through the oil storage cavity 102 and connect to the porous oil guide of the atomizing assembly 20. When the user places the electronic atomizing device 100 at rest, the oil tank assembly 30 can be at the same height as the atomizing assembly 20 and the two are located on opposite sides of the main body 10. The limiting groove 304 can be opened on a mounting bracket fixed to the lower side of the receiving cavity 302, and the blocking member 32 can also be fixed on another mounting bracket fixed to the lower side of the receiving cavity 302. The limiting groove 304 and the sealing member 31 are both located below the blocking member 32. The limiting groove 304 can be a through groove similar to a frustum. The upper area of ​​the limiting groove 304 is larger and faces the blocking member 32, while the lower area of ​​the limiting groove 304 is smaller and connects to the connecting channel 306.

[0033] The seal 31 may include a spherical plastic or metal structure. The diameter of the seal 31 is larger than the diameter of the lower side of the limiting groove 304 and smaller than the diameter of the upper side of the limiting groove 304, so that the seal 31 can be located within the limiting groove 304. The blocking member 32 may include a rectangular sheet structure. The distance between the blocking member 32 and the groove opening of the limiting groove 304 on the side facing the blocking member 32 is smaller than the diameter of the seal 31, so as to prevent the seal 31 from disengaging from the limiting groove 304.

[0034] When the blocking member 32 is above the sealing member 31, the sealing member 31 can cover the lower end of the limiting groove 304 under the action of gravity, so as to seal the connection between the limiting groove 304 and the connecting channel 306; when the blocking member 32 is below the sealing member 31, the sealing member 31 is separated from the side of the limiting groove 304 facing away from the blocking member 32 under the action of gravity and abuts against the blocking member 32, and the receiving cavity 302 is connected to the atomizing cavity 202 in sequence through the limiting groove 304 and the connecting channel 306.

[0035] In other embodiments, the main body 10 may also have other shapes, such as a cylindrical structure; the oil tank assembly 30 may also be detachable relative to the main body 10; the seal 31 may also include other structures, such as an ellipsoid; the oil tank assembly 30 may also be arranged around the atomizing assembly 20; the blocking member 32 may also include other structures, such as a circular sheet structure or an arc surface structure; in other embodiments, when the electronic atomizing device 100 is stationary, the blocking member 32 may be located below the seal 31, and correspondingly, the limiting groove 304 may be located above the receiving cavity 302.

[0036] In some embodiments, the main body 10 includes an oil-retaining cotton 12, and the main body 10 has an oil-retaining cavity 102. The oil-retaining cotton 12 is located in the oil-retaining cavity 102, and the oil-retaining cavity 102 is connected to the atomizing component 20.

[0037] With the above structure, a certain amount of e-liquid can be stored in the oil storage chamber 102 to increase the e-liquid capacity of the electronic atomizing device 100; the oil storage cotton 12 is located in the oil storage chamber 102 so that the e-liquid in the oil storage chamber 102 can be stored in the oil storage cotton 12, the e-liquid in the oil storage cotton 12 is difficult to leak, and the e-liquid in the oil storage cotton 12 will not shake during the transportation of the electronic atomizing device 100.

[0038] Specifically, in this embodiment, the oil storage cavity 102 can be arranged around the atomizing component 20, and the oil storage cotton 12 can be interconnected with the porous oil guide in the atomizing component 20 to achieve better e-liquid guiding effect; the porous oil guide in the atomizing component 20 and the oil storage cavity 102 can be connected through the through hole arranged around the atomizing component 20.

[0039] In other embodiments, the oil reservoir 102 may also be located on one side of the atomizing assembly 20.

[0040] In some embodiments, the connecting channel 306 includes a first vertical channel 3062, a first horizontal channel 3064, a second vertical channel 3066, and a second horizontal channel 3068 connected sequentially to each other. The upper end of the first vertical channel 3062 is connected to the limiting groove 304. The first horizontal channel 3064 is connected to the lower end of the first vertical channel 3062 and the lower end of the second vertical channel 3066. The upper end of the second vertical channel 3066 is connected to one end of the second horizontal channel 3068. The second horizontal channel 3068 passes through the oil storage chamber 102. The end of the second horizontal channel 3068 facing away from the second vertical channel 3066 is connected to the atomizing component 20.

[0041] Through the above structure, the connection between the first vertical flow channel 3062 and the first horizontal flow channel 3064, the connection between the first horizontal flow channel 3064 and the second vertical flow channel 3066, and the connection between the second vertical flow channel 3066 and the second horizontal flow channel 3068 can all play a buffering role for the e-liquid; so as to avoid excessive e-liquid flowing into the atomizing chamber 202 when the negative pressure between the atomizing chamber 202 and the receiving chamber 302 is too large, thereby avoiding the atomizing component 20 from being unable to completely heat the e-liquid in the atomizing chamber 202 to the atomized state.

[0042] Specifically, in this embodiment, the length of the first vertical flow channel 3062 is less than the length of the second vertical flow channel 3066, so that when the electronic atomizing device 100 is stationary, the height of the second horizontal flow channel 3068 is greater than the height of the upper end of the first vertical flow channel 3062, that is, the height of the second horizontal flow channel 3068 is greater than the height of the limiting groove 304. The second horizontal flow channel 3068 passes through the oil storage chamber 102, and the second horizontal flow channel 3068 is isolated from the oil storage chamber 102.

[0043] There are two first vertical flow channels 3062. The middle part of the first horizontal flow channel 3064 is connected to the lower end of the second vertical flow channel 3066. The two first vertical flow channels 3062 are located on opposite sides of the first horizontal flow channel 3064.

[0044] In other embodiments, the length of the first vertical flow channel 3062 may be greater than or equal to the length of the second vertical flow channel 3066; the number of the first vertical flow channel 3062 and the first horizontal flow channel 3064 may also be other, such as one.

[0045] In some embodiments, the electronic atomizing device 100 further includes an oil guide 40, which is installed within the second transverse flow channel 3068.

[0046] With the above structure, when there is too much e-liquid on the side of the second transverse flow channel 3068 away from the atomizing chamber 202, the oil guide 40 can absorb the e-liquid and block the excess e-liquid to prevent excessive e-liquid from flowing into the atomizing chamber 202; when there is less e-liquid on the side of the second transverse flow channel 3068 away from the atomizing chamber 202, the e-liquid in the oil guide 40 can continue to be replenished into the atomizing chamber 202 to prevent the atomizing chamber 202 from running out of e-liquid, so that the e-liquid in the receiving cavity 302 can flow into the atomizing chamber 202 stably.

[0047] Specifically, in this embodiment, the oil tank assembly 30 includes a first mounting bracket 34 and a second mounting bracket 35. A first vertical flow channel 3062 and a first horizontal flow channel 3064 are formed on the first mounting bracket 34, a second vertical flow channel 3066 is formed on the second mounting bracket 35, and the second horizontal flow channel 3068 may include a straight pipe with a circular cross-section and protrude relative to the second mounting bracket 35. The oil guide 40 may include a cylindrical cotton structure.

[0048] In other embodiments, the first vertical flow channel 3062, the first horizontal flow channel 3064, the second vertical flow channel 3066, and the second horizontal flow channel 3068 may also include other structures, such as straight pipes with rectangular or elliptical cross sections; the oil guide 40 may also include other structures, such as a cuboid cotton structure.

[0049] In some embodiments, there are two first vertical flow channels 3062, which are located on opposite sides of the first horizontal flow channel 3064; the extension direction of the first horizontal flow channel 3064 is perpendicular to the extension direction of the second horizontal flow channel 3068.

[0050] With the above structure, there are two first vertical flow channels 3062, which are respectively connected to the opposite sides of the first horizontal flow channel 3064. This allows e-liquid to flow into the connecting flow channel 306 from the two first vertical flow channels 3062. When the e-liquid in the receiving cavity 302 only covers the opening of one of the first vertical flow channels 3062, the e-liquid can also flow into the connecting flow channel 306, thereby reducing the possibility that the e-liquid cannot flow into the connecting flow channel 306.

[0051] Specifically, there are two of each limiting groove 304, sealing element 31 and blocking element 32, with each first vertical flow channel 3062 corresponding to one limiting groove 304, one sealing element 31 and one blocking element 32.

[0052] In some embodiments, the sealing member 31 is spherical, and the two ends of the limiting groove 304 have a first opening 3046 and a second opening 3048, respectively. The limiting groove 304 is connected to the receiving cavity 302 and the first vertical flow channel 3062 through the first opening 3046 and the second opening 3048, respectively. The diameter of the sealing member 31 is greater than the inner diameter of the first opening 3046 or the inner diameter of the second opening 3048.

[0053] The limiting groove 304 includes a flared end 3042 and a constricted end 3044 connected to each other. The first opening 3046 is located on the side of the flared end 3042 away from the constricted end 3044, and the second opening 3048 is located on the side of the constricted end 3044 away from the flared end 3042. The inner diameter of the first opening 3046 is larger than the inner diameter of the sealing member 31. The blocking member 32 is disposed on the side of the flared end 3042 away from the constricted end 3044, and the distance between the blocking member 32 and the first opening 3046 is smaller than the diameter of the sealing member 31.

[0054] With the above structure, the portion of the limiting groove 304 located at the closing end 3044 can be tilted when the electronic atomizing device 100 is placed horizontally, so that the seal 31 is disengaged from the second opening 3048, and the receiving cavity 302 can be connected to the atomizing component 20 through the limiting groove 304; thus, the user can inhale smoke when holding the electronic atomizing device 100 and placing the electronic atomizing device 100 flat.

[0055] In addition, the seal 31 is spherical, and the limiting groove 304 includes a constricted end 3044, and the second opening 3048 is located on the side of the constricted end 3044 away from the flared end 3042. The diameter of the seal 31 is larger than the inner diameter of the second opening 3048. When the seal 31 abuts against the side of the constricted end 3044 with a smaller area, the seal 31 can more easily seal the second opening 3048.

[0056] The first opening 3046 is located on the side of the flared end 3042 facing away from the closed end 3044. The inner diameter of the first opening 3046 is larger than the inner diameter of the seal 31. The blocking member 32 is disposed on the side of the flared end 3042 facing away from the closed end 3044. The distance between the blocking member 32 and the first opening 3046 is smaller than the diameter of the seal 31. This ensures that the seal 31 will not detach from the limiting groove 304 under the action of the blocking member 32, and the seal 31 can be stably placed in the limiting groove 304.

[0057] Specifically, the flared end 3042 is cylindrical, and the constricted end 3044 is frustum-shaped; the flared end 3042, the constricted end 3044, and the first vertical flow channel 3062 are connected in sequence, with the larger area side of the constricted end 3044 facing the flared end 3042; the diameter of the sealing element 31 is smaller than the diameter of the larger area side of the constricted end 3044, and the side of the flared end 3042 facing away from the constricted end 3044 forms a first opening 3046, while the side of the constricted end 3044 facing away from the constricted end 3044 forms a second opening 3048; the gap between the side of the flared end 3042 facing away from the constricted end 3044 and the blocking element 32 is smaller than the diameter of the sealing element 31, and part of the sealing element 31 is located inside the flared end 3042.

[0058] The length of the flared end 3042 can be less than the diameter of the seal 31, and the length of the flared end 3042 can be greater than the length of the constricted end 3044. The blocking member 32 can include a rectangular sheet structure, and the blocking member 32 can be perpendicular to the central axis of the flared end 3042.

[0059] In some embodiments, the oil tank assembly 30 includes a tank body 33, a first mounting bracket 34, and a second mounting bracket 35. The tank body 33 has a receiving cavity 302. The first mounting bracket 34 includes a first vertical flow channel 3062 and a first horizontal flow channel 3064. The second mounting bracket 35 includes a second vertical flow channel 3066 and a second horizontal flow channel 3068. The first mounting bracket 34 is mounted on one wall of the receiving cavity 302, and the second mounting bracket 35 is mounted on another adjacent wall of the receiving cavity 302. The second mounting bracket 35 is mounted on the first mounting bracket 34. A blocking member 32 is connected to one side of the second mounting bracket 35 and is located on one side of the second horizontal flow channel 3068.

[0060] With the above structure, the first mounting bracket 34 includes a first vertical flow channel 3062 and a first horizontal flow channel 3064, and the second mounting bracket 35 includes a second vertical flow channel 3066 and a second horizontal flow channel 3068; so as to facilitate the separate manufacturing of the first mounting bracket 34 and the second mounting bracket 35, and avoid including the first vertical flow channel 3062, the first horizontal flow channel 3064, the second vertical flow channel 3066 and the second horizontal flow channel 3068 in the same part, thereby avoiding the structure of a single part being too complex.

[0061] In addition, the blocking member 32 is connected to one side of the second mounting bracket 35, and the blocking member 32 is located on one side of the second transverse flow channel 3068; the second mounting bracket can provide installation space for the blocking member 32, and the second mounting bracket does not need to be connected to the cavity wall of the receiving cavity 302.

[0062] Specifically, the chamber 33, the first mounting bracket 34, and the second mounting bracket 35 can all be made of plastic; the first mounting bracket 34 and the second mounting bracket 35 can be connected to each other by snap-fit ​​or glue application; the second vertical flow channel 3066 can be inserted into the first mounting bracket 34 to improve the sealing of the connection between the first horizontal flow channel 3064 and the second vertical flow channel 3066; when the electronic atomizing device 100 is stationary, the first mounting bracket 34 can be fixed to the bottom wall of the receiving cavity 302, and the second mounting bracket 35 can be fixed to the side wall of the receiving cavity 302 near the atomizing component 20.

[0063] Please refer to Figures 6 to 10 In another embodiment of the present invention, the oil tank assembly 30 includes a tank body 33 and a connecting component 37. The tank body 33 is detachably installed on the connecting component 37. The tank body 33 has a receiving cavity 302. The connecting component 37 is installed on the main body 10. The sealing element 31 and the blocking element 32 are both installed on the connecting component 37. The connecting component 37 has a limiting groove 304 and a connecting flow channel 306. When the tank body 33 is installed on the connecting component 37, the receiving cavity 302 is connected to the atomizing cavity 202 in sequence through the limiting groove 304, the connecting flow channel 306 and the oil storage cavity 102.

[0064] With the above structure, the chamber 33 is detachably installed on the connecting component 37, and the connecting component 37 is installed on the main body 10. When the user needs to replace the chamber 33, the chamber 33 can be detached from the connecting component 37, and then the new chamber 33 can be installed on the connecting component 37, or e-liquid can be injected into the chamber 33, and then the chamber 33 after e-liquid injection can be installed on the connecting component 37, so as to realize the repeated use of the electronic atomizing device 100 in this embodiment.

[0065] Specifically, in this embodiment, the compartment 33 may include a hollow structure similar to a cylinder. The compartment 33 may be partially inserted into the main body 10, or the compartment 33 may be pulled out relative to the main body 10. The hollow part of the compartment 33 may form a receiving cavity 302. The compartment 33 may be detachably connected to the connecting component 37 by means of snap-fit ​​or threaded connection.

[0066] In other embodiments, the housing 33 may also include other structures, such as a hollow structure similar to a cuboid.

[0067] In some embodiments, the oil tank assembly 30 further includes a switch component 36, which is mounted on the tank body 33. When the tank body 33 is mounted on the connecting component 37, the switch component 36 contacts the side of the blocking member 32 facing away from the seal member 31 and opens, and the receiving cavity 302 communicates with the limiting groove 304. When the tank body 33 is disassembled relative to the connecting component 37, the switch component 36 closes and seals the receiving cavity 302.

[0068] With the above structure, when the chamber 33 is installed on the connecting component 37, the switch component 36 contacts the side of the blocking component 32 facing away from the sealing component 31 and opens, and the receiving cavity 302 is connected to the limiting groove 304; when the chamber 33 is installed on the connecting component 37, the e-liquid in the receiving cavity 302 can flow into the atomizing cavity 202 through the limiting groove 304 and the connecting channel 306, and the atomizing component 20 can heat the e-liquid to form gaseous smoke for the user to inhale.

[0069] When the housing 33 is disassembled from the connecting component 37, the switch component 36 closes and seals the receiving cavity 302; when the housing 33 is disassembled from the connecting component 37, the receiving cavity 302 is sealed, which can prevent e-liquid leakage during the centralized transportation of the housing 33.

[0070] Specifically, in this embodiment, the switch component 36 may include a compression structure. When the housing 33 is installed on the connecting component 37, the compression structure is compressed, the opening of the switch component 36 is exposed, and the receiving cavity 302 communicates with the limiting groove 304. When the housing 33 is disassembled relative to the connecting component 37, the compression structure is reset, the opening of the switch component 36 is closed, and the switch component 36 closes and seals the receiving cavity 302.

[0071] In other embodiments, the switch component 36 may also include other structures, such as a multi-lobed isolation membrane that can be pushed open. The multi-lobed isolation membrane is elastic so that it can automatically reset and seal the receiving cavity 302. When the switch component 36 is installed on the connecting component 37, the connecting component 37 can push open the isolation membrane, and the receiving cavity 302 communicates with the limiting groove 304. When the housing 33 is disassembled relative to the connecting component 37, the isolation membrane resets, and the switch component 36 closes and seals the receiving cavity 302.

[0072] In some embodiments, the switch component 36 includes a guide sleeve 362, a slider 364, and an elastic reset component 366. The slider 364 has a communicating groove 3602, is disposed in the guide sleeve 362, and can slide axially relative to the guide sleeve 362. The elastic reset component 366 is installed between the guide sleeve 362 and the slider 364.

[0073] When the housing 33 is installed on the connecting component 37, the blocking member 32 abuts against the sliding member 364, causing the sliding member 364 to move away from the blocking member 32 relative to the guide sleeve 362. The elastic reset member 366 is compressed, the connecting groove 3602 is misaligned with the guide sleeve 362, and the receiving cavity 302 is connected to the limiting groove 304 through the connecting groove 3602.

[0074] When the compartment 33 is disassembled relative to the connecting component 37, the elastic reset component 366 resets and drives the sliding component 364 to move toward the blocking component 32. The guide sleeve 362 covers the connecting groove 3602, and the receiving cavity 302 is sealed.

[0075] With the above structure, during the installation of the compartment 33 onto the connecting component 37, the blocking member 32 abuts against the sliding member 364 and drives the sliding member 364 to move relative to the guide sleeve 362. The elastic reset member 366 is compressed until the connecting groove 3602 on the sliding member 364 and the guide sleeve 362 are misaligned, that is, the receiving cavity 302 can be connected to the limiting groove 304 through the connecting groove 3602. Finally, the compartment 33 and the connecting component 37 are fixed together.

[0076] After the chamber body 33 is disassembled from the connecting component 37, during the process of the chamber body 33 separating from the main body 10, the elastic reset component 366 gradually resets, so as to drive the sliding component 364 to move relative to the guide sleeve 362 until the connecting groove 3602 on the sliding component 364 is covered by the guide sleeve 362, and the switch component 36 can seal the receiving cavity 302.

[0077] Specifically, the guide sleeve 362 can be made of plastic and may include a cylindrical structure. The guide sleeve 362 may include a first mounting step 3622, which is located on the side of the guide sleeve 362 facing away from the blocking member 32. The sliding member 364 may be a hollow cylindrical structure and may include a second mounting step 3642 and an abutment post 3644. The second mounting step 3642 is located on the side of the sliding member 364 facing the blocking member 32. There is a gap between the inner side of the guide sleeve 362 and the outer side of the sliding member 364. Both the first mounting step 3622 and the second mounting step 3642 are annular and placed between the sliding member 364 and the guide sleeve 362. The elastic reset member 366 may include a compression spring and is located between the sliding member 364 and the guide sleeve 362. One end of the elastic reset member 366 abuts against the first mounting step 3622, and the other opposite end abuts against the second mounting step 3642.

[0078] The sliding member 364 has a mounting cavity 3646 on the side facing the blocking member 32. A connecting groove 3602 is provided on the periphery of the sliding member 364. The connecting groove 3602 can be in a rectangular shape. The connecting groove 3602 can communicate with the limiting groove 304 through the mounting cavity 3646. The abutting post 3644 includes a columnar structure coaxially arranged with the sliding member 364. One end of the abutting post 3644 is connected to the cavity wall of the mounting cavity 3646. The other end of the abutting post 3644 faces the blocking member 32. The blocking member 32 can contact the abutting post 3644 and drive the sliding member 364 to move relative to the guide sleeve 362.

[0079] The connecting component 37 may include a plastic block fixed to the main body 10, and the blocking component 32 may include a mesh structure similar to an arc surface. When the electronic atomizing device 100 is stationary, the sealing component 31 may be located above the blocking component 32. The sealing component 31 and the groove wall of the limiting groove 304 together surround the sealing component 31 to prevent the sealing component 31 from falling out of the limiting groove 304.

[0080] The limiting groove 304 can have a structure similar to a frustum. When the electronic atomizing device 100 is stationary, the inner diameter of the upper opening of the limiting groove 304 is smaller than the diameter of the seal 31 and is connected to the connecting channel 306. The inner diameter of the lower opening of the limiting groove 304 is larger than the diameter of the seal 31 and is connected to the receiving cavity 302.

[0081] When the user holds the electronic atomizing device 100 and places it flat, the sealing member 31 can slide along the wall of the limiting groove 304 under the action of gravity to the opening of the connecting channel 306 facing away from the limiting groove 304, and the receiving cavity 302 can be connected to the connecting channel 306 through the limiting groove 304.

[0082] When the user lifts the electronic atomizing device 100, the seal 31 can slide under the action of gravity and seal the opening of the limiting groove 304 that connects to the connecting channel 306. The limiting groove 304 is sealed to prevent excessive e-liquid in the receiving cavity 302 from flowing into the connecting channel 306 and causing oil leakage.
