[0038] In order to describe the present invention more clearly, the present invention will be further described below with reference to the accompanying drawings.

[0039] It should be understood that terms such as "front", "rear", "left", "right", "upper", "lower", "first", "second", etc. are only for the convenience of describing the technical solution of the present invention, rather than indicating that the device or element referred to must have special differences, so it cannot be understood as a limitation to the present invention. It should be noted that when a part is considered to be "connected" to another part, it can be directly connected to the other part or there may be an intermediate part at the same time. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention in this specification are only for the purpose of describing specific embodiments, and are not intended to limit the present invention.

[0040] Figure 1-2 Some embodiments of the electronic atomization device of the present invention are shown. The electronic atomization device can be applied to the heating atomization of liquid matrices such as e-liquid and liquid drugs. It can generally be in a cylindrical shape and includes a cylindrical atomizer 1 and a cylindrical main body 4 that is axially detachably connected to the atomizer 1. The atomizer 1 is used to accommodate the liquid matrix, heat and atomize the liquid matrix, and convey the mist. The main body 4 is used to supply power to the atomizer 1 and control operations such as turning on or off the entire electronic atomization device. It can be understood that the electronic atomization device is not limited to a cylindrical shape, and it can also be in other shapes such as an elliptical cylinder or a square.

[0041] As Figure 3-4As shown, in some embodiments, the main unit 4 may include a cylindrical housing 41 with a receiving cavity 410, a conductive connector 42 disposed at the top of the housing 41, a cylindrical first electrode post 43 insulatingly disposed in the connector 42, and a battery device 45 and an air switch 46 disposed in the receiving cavity 410.

[0042] The connector 42 is used to connect with the atomizer 1. It can be made of metal, such as stainless steel, preferably 316 medical-grade stainless steel without heavy metals. In some embodiments, the connector 42 may include a cylindrical body portion 421 and a flange portion 422 integrally joined to the upper part of the body portion 421 along the longitudinal direction. The outer diameter of the body portion 421 is adapted to the inner diameter of the housing 41 to be tightly embedded in the housing 41. Usually, the two can be fixed to each other by riveting. An internal thread is formed on the inner wall surface of the body portion 421 for screwing with the atomizer 1. The outer diameter of the flange portion 422 is larger than the outer diameter of the body portion 421 and can be equivalent to the outer diameter of the housing 41. The flange portion 422 abuts against the upper side of the housing 41 to achieve positioning during assembly.

[0043] At least one air inlet hole 4221 is formed on the flange portion 422 to allow external air to enter the receiving cavity 410. The at least one air inlet hole 4221 is opened on the flange portion 422 and can be formed by inward depression from the outer edge of the flange portion 422, so as to avoid specially opening holes on the housing 41, saving the processing technology, and at the same time ensuring the aesthetics and integrity of the product appearance. At least one air guiding groove 4211 is formed on the outer wall surface of the body portion 421. The at least one air guiding groove 4211 is correspondingly arranged with the at least one air inlet hole 4221. The at least one air guiding groove 4211 extends downward from the upper end surface of the body portion 421, thereby connecting the air inlet hole 4221 with the receiving cavity 410. The air inlet hole 4221, the air guiding groove 4211, the receiving cavity 410, and the central through hole of the first electrode post 43 together form a first induction air passage.

[0044] The first electrode post 43 is insulatingly disposed in the body portion 421. Insulation can be achieved by providing an insulating sleeve 44 between the outer ring of the first electrode post 43 and the inner ring of the body portion 421. The connector 42 and the first electrode post 43 are electrically connected to the negative electrode and the positive electrode (or the positive electrode and the negative electrode) of the battery device 45 respectively.

[0045] As Figure 5-9 shown, in some embodiments, the atomizer 1 may include a base assembly 10 for detachably connecting with the main unit 4, an atomizer body 20 longitudinally mounted on the upper end of the base assembly 10, and a mouthpiece assembly 30 longitudinally mounted on the upper end of the atomizer body 20. The base assembly 10, the atomizer body 20, and the mouthpiece assembly 30 can be coaxially combined together.

[0046] In some embodiments, the base assembly 10 may include a conductive base 11, a second electrode post 12 longitudinally and insulatingly disposed in the base 11, and an induction duct 13 longitudinally penetrating through the upper end of the second electrode post 12. The base 11 is used to connect and conductively contact with the connector 42 of the host 4. The base 11 may be made of a metal material, such as stainless steel, preferably 316 heavy-metal-free medical-grade stainless steel. In some embodiments, the base 11 may include a cylindrical seat body 111 and a cylindrical joint portion 112 integrally and longitudinally joined to the lower portion of the seat body 111. The outer diameter of the joint portion 112 may be smaller than the outer diameter of the seat body 111, and an external thread may be formed on its outer wall surface for screwing with the main body portion 421 of the connector 42. The seat body 111 presses against the upper side of the flange portion 422, and its outer diameter may be comparable to the outer diameters of the flange portion 422 and the housing 41.

[0047] The second electrode post 12 is used for electrically contacting with the first electrode post 43, and the central through holes of the two are connected and communicated. The second electrode post 12 is longitudinally and insulatingly disposed in the joint portion 112. Generally, insulation can be achieved by providing an insulating sleeve 14 between the outer circle of the second electrode post 12 and the inner circle of the joint portion 112.

[0048] The central through hole of the second electrode post 12 and the central through hole of the induction duct 13 are connected and communicated to form a second induction air duct. This second induction air duct and the first induction air duct together form the air switch induction air duct of the electronic atomization device for controlling the operation of the air switch 46. Specifically, when inhaling from the outside, the air flow passes through the air inlet hole 4221, the air guide groove 4211, the accommodation cavity 410, the first electrode post 43, enters the second electrode post 12 and the induction duct 13 in sequence. During this process, a negative pressure is formed in the accommodation cavity 410, and the air switch 46 is activated under the negative pressure.

[0049] The outer diameter of the induction duct 13 may be adapted to the inner diameter of the second electrode post 12 (for example, slightly smaller than the inner diameter of the second electrode post 12) to be tightly embedded in the second electrode post 12. Generally, the two can be fixed to each other by riveting. In some embodiments, the induction duct 13 may be a vertical slender tube, and its outer diameter may be 0.3 cm to 1.1 cm. Due to the fact that the induction duct 13 is thin and long, a small amount of condensate will adhere to the induction duct 13 due to surface tension and is not easily introduced into the host 4. The induction duct 13 may be made of a metal material, such as stainless steel, preferably 316 heavy-metal-free medical-grade stainless steel.

[0050] In some embodiments, the atomizer body 20 may include a housing 21 longitudinally mounted on top of the base 11, an outer tube 22 longitudinally disposed in the housing 21, an atomization assembly 25 disposed in the outer tube 22, and an inner tube 27 longitudinally disposed in the outer tube 22 and above the atomization assembly 25. Both the outer tube 22 and the inner tube 27 can be made of metal, such as stainless steel, preferably 316 non-heavy metal medical grade stainless steel.

[0051] In some embodiments, the atomization assembly 25 may include a liquid absorbent 251, a heating element disposed on the liquid absorbent 251, and two electrode leads 253 connected to the heating element. The two electrode leads 253 are electrically connected to the base 11 and the second electrode post 12 respectively.

[0052] The liquid absorbent 251 can be a porous ceramic. In some embodiments, it may include a main body portion 2511, two clamping arms 2512 respectively disposed on two opposite sides of the upper end of the main body portion 2511, an extension portion 2513 disposed on the upper part of the main body portion 2511, and a central through hole 2510 longitudinally penetrating the main body portion 2511 and the extension portion 2513. The heating element can be disposed on the inner wall of the through hole 2510 for heating and atomizing the liquid matrix adsorbed in the liquid absorbent 251 after being powered on. The through hole 2510 forms an atomization chamber for mixing the mist and air generated by the atomization assembly 25. The main body portion 2511 can be generally longitudinally rectangular, etc. The two clamping arms 2512 are respectively disposed on two opposite sides in the longitudinal direction of the upper end of the main body portion 2511. The extension portion 2513 can be cylindrical, and the extension portion 2513 can increase the axial length of the through hole 2510 and increase the installation space for the heating element.

[0053] A liquid storage chamber 210 for storing the liquid matrix is defined between the inner wall surface of the housing 21 and the outer wall surface of the outer tube 22. At least one liquid inlet 2210 is provided on the outer tube 22 to allow the liquid matrix in the liquid storage chamber 210 to enter the outer tube 22 through the at least one liquid inlet 2210, so as to conductively connect the liquid absorbent 251 with the liquid storage chamber 210. An air intake duct 220 is defined between the inner wall surface of the outer tube 22 and the outer wall surface of the inner tube 27, and the air intake duct 220 is communicated with the air inlet of the atomization chamber to allow external air to enter the atomization chamber. The inner wall surface of the inner tube 27 defines an air outlet duct 270, and the air outlet duct 270 is communicated with the air outlet of the atomization chamber to export the mist and air mixture in the atomization chamber.

[0054] In some embodiments, the housing 21 can be cylindrical, and its outer diameter can be equivalent to the outer diameter of the outer shell 41. An inner ring at the lower end of the housing 21 extends radially inward to form a neck 211, and the inner diameter of the neck 211 can be equivalent to the inner diameter of the seat body 111 of the base 11. The housing 21 presses against the top of the seat body 111 with the neck 211. A sealing ring 15 can also be provided between the bottom of the neck 211 and the top of the seat body 111 to prevent liquid leakage.

[0055] In some embodiments, the outer tube 22 may include a first tube section 221 located at the lower part, a second tube section 222 located in the middle, and a third tube section 223 located at the upper part. The inner diameter and outer diameter of the first tube section 221, the second tube section 222, and the third tube section 223 are all decreasing, such that the outer tube 22 is in the shape of a stepped shaft. The outer diameter of the inner tube 27 is smaller than the inner diameter of the third tube section 223, thereby defining an annular intake duct 220 between the inner wall surface of the third tube section 223 and the outer wall surface of the inner tube 27. The outer diameter of the first tube section 221 is adapted to the inner diameter of the housing 21 so that the two can be closely sleeved together. The outer wall surfaces of the second tube section 222 and the third tube section 223 and the inner wall surface of the housing 21 define a liquid storage chamber 210. The main body portion 2511 of the liquid absorbent 251 and the two clamping arms 2512 are disposed in the first tube section 221, and the extending portion 2513 extends upward from the top surface of the main body portion 2511 and extends into the second tube section 222. A liquid inlet 2210 is respectively formed on both sides of the top wall of the first tube section 221, and the two liquid inlets 2210 are respectively arranged corresponding to the two clamping arms 2512 of the liquid absorbent 251. The side surface and the end surface of the clamping arm 2512 absorb liquid, and the main body portion 2511 and the extending portion 2513 are hermetically connected to the outer tube 22, such that the liquid absorbent can both block the liquid matrix and ensure a good liquid guiding effect. In some embodiments, the distance between the end surfaces of the two clamping arms 2512 is smaller than the inner diameter of the first tube section 221, so that a gap is respectively formed between the two clamping arms 2512 and the first tube section 221. This gap is conducive to liquid flowing down and liquid absorption, and can also prevent the liquid absorbent 251 from directly conducting heat in contact with the outer tube 22.

[0056] In some embodiments, the atomizer body 20 may further include a connecting member 23 for connecting the atomizer body 20 and the base assembly 10. The connecting member 23 may be made of a metal material, such as stainless steel. Its upper end is embedded in the outer tube 22, and its lower end extends out of the housing 21 and is embedded in the base 11, thereby realizing the fixation among the housing 21, the outer tube 22, and the base 11. In some embodiments, the connecting member 23 may be in a cylindrical shape and may include a cylindrical lower embedding portion 231 located at the lower part and a cylindrical upper embedding portion 232 located at the upper part. The outer diameter of the lower embedding portion 231 is adapted to the aperture of the base hole 1110 on the base body 111 of the base 11, and after passing through the neck portion 211 of the housing 21, it is closely embedded in the base body 111. The outer diameter of the upper embedding portion 232 is larger than the outer diameter of the lower embedding portion 231 and the inner diameter of the neck portion 211, and is adapted to the inner diameter of the first tube section 221 of the outer tube 22, so as to be closely embedded in the first tube section 221. An annular retaining wall 233 is formed at the junction of the upper embedding portion 232 and the lower embedding portion 231, and the retaining wall 233 presses against the upper side of the neck portion 211. In some embodiments, an O-ring 28 may further be provided between the lower side of the retaining wall 233 and the upper side of the neck portion 211 to prevent liquid leakage.

[0057] In some embodiments, the atomizer body 20 may further include an atomization base 24 and a mounting base 26. The atomization assembly 25 is received in the space formed between the atomization base 24 and the mounting base 26. The atomization base 24 is disposed below the atomization assembly 25, and its lower end is embedded in the connecting member 23. The mounting base 26 at least partially surrounds the upper part of the atomization assembly 25, and the lower end of the inner tube 27 is embedded in the mounting base 26.

[0058] The induction duct 13 sequentially penetrates through the atomization base 24, the atomization assembly 25, and the mounting base 26 from bottom to top and then extends into the inner tube 27, and is longitudinally suspended in the inner tube 27 (that is, the air outlet end does not contact the inner wall surface of the inner tube 27). By arranging the induction duct 13 in the inner tube 27, the inherent space in the structure is fully utilized, the design difficulty of the induction air duct can be reduced, space can be saved, and costs can be reduced. In some embodiments, the upper air outlet end of the induction duct 13 is preferably higher than the plane where the top surface of the mounting base 26 is located to prevent condensate from entering the induction duct 13 and causing blockage, and at the same time, it can also prevent condensate from entering the main body 4 through the induction duct 13. The upper air outlet end of the induction duct 13 is preferably lower than 2 / 3 of the height of the inner tube 27 from bottom to top to prevent the induction duct 13 from being too long and prone to tilting, resulting in poor air flow and thus reducing the sensitivity of induction.

[0059] In some embodiments, the mounting base 26 can be made of a soft material such as silica gel. It may include a socket part 261 located at the lower part, an embedding part 262 located at the upper part, and a mounting hole 260 longitudinally penetrating through the socket part 261 and the embedding part 262. The outer diameter of the socket part 261 is adapted to the inner diameter of the first pipe section 221 to be tightly embedded in the first pipe section 221. The top of the socket part 261 can be pressed against the junction of the first pipe section 221 and the second pipe section 222. The outer diameter of the embedding part 262 is adapted to the inner diameter of the second pipe section 222 to be tightly embedded in the second pipe section 222. The mounting hole 260 is respectively communicated with the air outlet duct 270 and the through hole 2510 of the liquid absorber 251 to communicate the through hole 2510 with the air outlet duct 270.

[0060] The socket part 261 is tightly sleeved outside the main body part 2511 of the liquid absorber 251. An opening 2610 is respectively formed on both sides of the top of the socket part 261, and the two openings 2610 are respectively arranged corresponding to the two clamping arms 2512 of the liquid absorber 251, so that the two clamping arms 2512 are exposed and thus are in liquid guiding communication with the liquid storage cavity 210.

[0061] On two opposite sides of the inner wall surface of the socket part 261, there is respectively provided a second air guide groove 2611 extending longitudinally. On two opposite sides of the outer wall surface of the embedding part 262, there is respectively provided a first air guide groove 2621 extending longitudinally. The two first air guide grooves 2621 are respectively arranged corresponding to and communicated with the two second air guide grooves 2611. The first air guide groove 2621 connects the air inlet pipe 220 and the second air guide groove 2611. The opening 2610 is circumferentially offset from the second air guide groove 2611, which is beneficial to liquid dropping, liquid suction and air intake.

[0062] The bottom of the embedding part 262 presses against the upper side of the main body part 2511. The mounting hole 260 includes a first mounting hole 2622 and a second mounting hole 2623 that penetrate through the middle of the embedding part 262 longitudinally. The first mounting hole 2622 is located below the second mounting hole 2623 and the aperture of the first mounting hole 2622 is larger than that of the second mounting hole 2623. The aperture of the first mounting hole 2622 is adapted to the outer diameter of the extending part 2513 of the liquid absorbing body 251 so that the two can be closely sleeved together. There is a certain interval between the top of the extending part 2513 and the bottom of the hole of the second mounting hole 2623 to prevent direct heat conduction by contact. The aperture of the second mounting hole 2623 is adapted to the outer diameter of the inner tube 27 so that the lower end of the inner tube 27 is closely embedded in the second mounting hole 2623.

[0063] In some embodiments, the atomizing seat 24 can be made of a soft material such as silica gel. It can include an insertion part 241 longitudinally embedded in the connecting part 23 and a flange part 242 connected to the upper part of the insertion part 241. The insertion part 241 can include a first insertion part 2411 at the lower part and a second insertion part 2412 at the upper part. The outer diameter of the first insertion part 2411 is adapted to the inner diameter of the lower embedding part 231 so as to be closely embedded in the lower embedding part 231. There is an interval between the bottom of the first insertion part 2411 and the bottom of the hole of the base hole 1110 of the base 11, which is beneficial to heat insulation. The outer diameter of the second insertion part 2412 is adapted to the inner diameter of the upper embedding part 232 so as to be closely embedded in the upper embedding part 232. The flange part 242 presses against the upper side of the upper embedding part 232, and the outer diameter of the flange part 242 can be adapted to the inner diameter of the first pipe section 221 so that the two can be closely sleeved together.

[0064] The main body 2511 of the liquid absorber 251 and the socket part 261 of the mounting base 26 are both pressed against the top surface of the flange part 242, thereby tightly clamping the atomization assembly 25 between the atomization base 24 and the mounting base 26. A first groove 2401 is formed by concave down the top surface of the flange part 242, and second grooves 2402 are respectively located on two opposite sides of the first groove 2401. The two second grooves 2402 are respectively arranged corresponding to and communicated with two second air guide grooves 2611, and the first groove 2401 is arranged corresponding to the liquid absorber 251 and communicated with the through hole 2510, thereby communicating the second air guide groove 2611 with the through hole 2510.

[0065] The insertion part 241 may include a first slot hole 2410 located in the middle and two second slot holes 2413 respectively located on two opposite sides of the first slot hole 2410. The first slot hole 2410 and the second slot holes 2413 both extend from the lower end surface of the insertion part 241 towards the flange part 242.

The structure of top air inlet and top air outlet can also alleviate liquid leakage from the air inlet hole 3110.

[0069] The mouthpiece 31 is detachably sealed at the upper end of the liquid storage cavity 210 so that the liquid matrix can be added. In some embodiments, the mouthpiece 31 may include a middle portion 311, an embedding portion 312 connected to the lower part of the middle portion 311, and a mouthpiece portion 313 connected to the upper part of the middle portion 311. The embedding portion 312 is sealingly blocked at the upper end opening of the housing 21. The outer diameter of the middle portion 311 is adapted to the outer diameter of the housing 21, and the bottom of the middle portion 311 abuts against the top of the housing 21. An air inlet hole 3110 is respectively opened on two opposite sides of the middle portion 311. The air inlet hole 3110 can be in the shape of a flared mouth, and its large head end is communicated with the external air, and its small head end is communicated with the air inlet pipe 220.

[0070] The air outlet hole 310 longitudinally penetrates through the mouthpiece portion 313, the middle portion 311, and the embedding portion 312. The air outlet hole 310 may include a first stepped hole 3101, a second stepped hole 3102, and a third stepped hole 3103 arranged in sequence from bottom to top, and the diameters of the first stepped hole 3101, the second stepped hole 3102, and the third stepped hole 3103 are all decreasing. The diameter of the third stepped hole 3103 is adapted to the outer diameter of the inner tube 27 so that the upper end of the inner tube 27 is tightly embedded in the third stepped hole 3103.

[0071] The fastener 32 is arranged on the hole wall of the second stepped hole 3102. In some embodiments, the fastener 32 may be in a cylindrical shape, and several strengthening holes 321 may be opened on its cylindrical side wall. During injection molding, a part of the mouthpiece 31 can be melted into the strengthening holes 321, so that the combination is tighter. In this embodiment, four strengthening holes 321 are evenly spaced circumferentially on the cylindrical side wall of the fastener 32. The inner diameter of the fastener 32 is adapted to the outer diameter of the third pipe section 223 of the outer pipe 22 so that an interference fit is formed between the top of the third pipe section 223 and the fastener 32, and the connection is more firm. The top of the third pipe section 223 can abut against the bottom surface of the second stepped hole 3102.

[0072] The third pipe section 223 is in sealing fit with the pore wall of the third stepped hole 3103. Usually, a sealing ring 33 is arranged between the outer side wall of the third pipe section 223 and the pore wall of the third stepped hole 3103 for sealing. In some embodiments, the sealing ring 33 can be made of a flexible material, such as silica gel, which is beneficial to improving the sealing effect. At least one retaining wall 2231 can be formed on the outer side wall of the third pipe section 223 for press-fitting and positioning the sealing ring 33. In this embodiment, two annular retaining walls 2231 are formed by stretch molding at the upper end of the third pipe section 223. The retaining walls 2231 are spaced along the axial direction of the third pipe section 223, and the upper and lower sides of the sealing ring 33 respectively abut against the two retaining walls 2231.

[0073] When the electronic atomization device works, the user inhales from the nozzle part 313 of the nozzle 31. The negative pressure generated by inhalation is transmitted to the air switch induction air passage through the air outlet passage of the mist delivery passage, and the air switch 46 is turned on, enabling the power supply device 45 to supply power to the atomization assembly 25 to start atomizing the liquid matrix. At the same time, external air enters the atomization chamber through the air inlet passage of the mist delivery passage and is mixed with the mist. The mixture of the mist and air then enters the user's mouth through the air outlet passage of the mist delivery passage.
