[0039] In order to more clearly illustrate the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0040] It should be understood that the terms "front", "rear", "left", "right", "upper", "lower", "first", "second", etc. are only for the convenience of describing the technical solution of the present invention, and do not indicate that the devices or elements referred to must have special differences, and therefore cannot be understood as limitations on the present invention. It should be noted that when a piece is considered to be "connected" to another piece, it can be directly connected to the other piece or there may be a central piece at the same time. Unless otherwise defined, all technical and scientific terms used in this document have the same meaning as commonly understood by technicians in the technical field to which the present invention belongs. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0041] Figure 1-2 The electronic atomization device in some embodiments of the present invention is shown. The electronic atomization device can be used for heating and atomizing liquid matrices such as cigarette liquid and liquid medicine. It can be roughly cylindrical and includes a cylindrical atomizer 1 and a cylindrical host 4 axially detachably connected to the atomizer 1. The atomizer 1 is used to accommodate the liquid matrix, heat and atomize the liquid matrix, and transport the mist. The host 4 is used to power the atomizer 1 and control the opening or closing of the entire electronic atomization device. It can be understood that the electronic atomization device is not limited to being cylindrical, and it can also be in other shapes such as an elliptical cylinder and a square.

[0042] like Figure 3-4 As shown, in some embodiments, the host 4 may include a cylindrical shell 41 with a receiving cavity 410, a conductive connector 42 arranged on the top of the shell 41, a cylindrical first electrode column 43 insulatedly arranged in the connector 42, and a battery device 45 and an air switch 46 arranged in the receiving cavity 410.

[0043] The connector 42 is used to connect to the atomizer 1, and it can be made of metal, such as stainless steel, preferably 316 medical grade stainless steel that does not contain heavy metals. In some embodiments, the connector 42 may include a cylindrical body portion 421 and a flange portion 422 that is integrated with the upper portion of the body portion 421 in the longitudinal direction. The outer diameter of the body portion 421 is adapted to the inner diameter of the outer shell 41 so as to be tightly embedded in the outer shell 41, and the two can usually be fixed to each other by riveting. The inner wall surface of the body portion 421 is formed with an internal thread 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 outer shell 41. The flange portion 422 is pressed against the upper side of the outer shell 41 to achieve positioning during assembly.

[0044] 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 provided on the flange portion 422 and can be formed by the outer edge of the flange portion 422 being recessed inward, thereby avoiding the need to open a special hole on the shell 41, saving processing technology, and ensuring the beauty and integrity of the product appearance. At least one air guide groove 4211 is formed on the outer wall surface of the body portion 421, and the at least one air guide groove 4211 is arranged corresponding to the at least one air inlet hole 4221. The at least one air guide 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 guide groove 4211, the receiving cavity 410, and the central through hole of the first electrode column 43 together form a first sensing airway.

[0045] The first electrode column 43 is insulated and disposed in the body 421. The outer ring of the first electrode column 43 and the inner ring of the body 421 can be insulated by disposing an insulating sleeve 44. The connector 42 and the first electrode column 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.

[0046] like Figure 5-9 As shown, in some embodiments, the atomizer 1 may include a base assembly 10 for detachably connecting to the host 4, an atomizer body 20 longitudinally mounted on the upper end of the base assembly 10, and a nozzle assembly 30 longitudinally mounted on the upper end of the atomizer body 20. The base assembly 10, the atomizer body 20, and the nozzle assembly 30 may be coaxially combined together.

[0047] In some embodiments, the base assembly 10 may include a conductive base 11, a second electrode column 12 insulatedly disposed in the base 11 along the longitudinal direction, and a sensing pipe 13 passing through the upper end of the second electrode column 12 along the longitudinal direction. The base 11 is used to connect and contact the connector 42 of the host 4. The base 11 can be made of metal, such as stainless steel, preferably 316 medical grade stainless steel without heavy metals. In some embodiments, the base 11 may include a cylindrical seat body 111 and a cylindrical coupling portion 112 integrally coupled to the lower part of the seat body 111 along the longitudinal direction. The outer diameter of the coupling portion 112 may be smaller than the outer diameter of the seat body 111, and its outer wall surface may be formed with an external thread for screwing with the main body 421 of the connector 42. The seat body 111 is pressed against the upper side of the flange portion 422, and its outer diameter may be equivalent to the outer diameters of the flange portion 422 and the outer diameter of the housing 41.

[0048] The second electrode column 12 is used to electrically contact the first electrode column 43, and the central through holes of the two are connected. The second electrode column 12 is insulated and arranged in the joint part 112 along the longitudinal direction. Generally, an insulating sleeve 14 can be arranged between the outer ring of the second electrode column 12 and the inner ring of the joint part 112 for insulation.

[0049] The central through hole of the second electrode column 12 is connected to the central through hole of the sensing pipe 13 to form a second sensing airway. The second sensing airway and the first sensing airway together form an air switch sensing airway for controlling the operation of the air switch 46 of the electronic atomization device. Specifically, when the outside world inhales air, the airflow passes through the air inlet 4221, the air guide groove 4211, the receiving cavity 410, the first electrode column 43 in sequence and enters the second electrode column 12 and the sensing pipe 13. In the process, a negative pressure is formed in the receiving cavity 410, and the air switch 46 is activated under the negative pressure.

[0050] The outer diameter of the sensing pipe 13 can be matched with the inner diameter of the second electrode column 12 (for example, slightly smaller than the inner diameter of the second electrode column 12) so as to be tightly embedded in the second electrode column 12, and the two can usually be fixed to each other by riveting. In some embodiments, the sensing pipe 13 can be a vertical slender tube, and its outer diameter can be 0.3 cm to 1.1 cm. Since the sensing pipe 13 is thin and long, a small amount of condensate will adhere to the sensing pipe 13 due to surface tension and will not easily enter the host 4. The sensing pipe 13 can be made of metal, such as stainless steel, preferably 316 heavy metal-free medical grade stainless steel.

[0051] In some embodiments, the atomizer body 20 may include a housing 21 longitudinally mounted on the top of the base 11, an outer tube 22 longitudinally disposed in the housing 21, an atomizing assembly 25 disposed in the outer tube 22, and an inner tube 27 longitudinally disposed in the outer tube 22 and located above the atomizing assembly 25. Both the outer tube 22 and the inner tube 27 may be made of metal, such as stainless steel, preferably 316 medical grade stainless steel that does not contain heavy metals.

[0052] In some embodiments, the atomization assembly 25 may include an absorbent liquid 251 , a heating element disposed on the absorbent liquid 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 column 12 , respectively.

[0053] The liquid absorbing liquid 251 may be a porous ceramic, which in some embodiments may include a main body 2511, two clamping arms 2512 respectively arranged at two opposite sides of the upper end of the main body 2511, an extension 2513 arranged at the upper part of the main body 2511, and a central through hole 2510 that passes through the main body 2511 and the extension 2513 in the longitudinal direction. The heating element may be arranged on the hole wall of the through hole 2510, and is used to heat and atomize the liquid matrix adsorbed in the liquid absorbing liquid 251 after power is turned on. The through hole 2510 forms an atomization chamber for mixing the mist and air generated by the atomization assembly 25. The main body 2511 may be roughly rectangular or other longitudinally long shapes, and the two clamping arms 2512 are respectively arranged at two opposite sides of the upper end of the main body 2511 in the longitudinal direction. The extension 2513 may be cylindrical, and the extension 2513 may increase the axial length of the through hole 2510 and increase the installation space of the heating element.

[0054] A liquid storage chamber 210 for storing liquid matrix is ​​defined between the inner wall surface of the shell 21 and the outer wall surface of the outer tube 22. At least one liquid inlet 2210 is provided on the outer tube 22, so that the liquid matrix in the liquid storage chamber 210 can enter the outer tube 22 through the at least one liquid inlet 2210, thereby connecting the liquid absorbing liquid 251 with the liquid storage chamber 210. The inner wall surface of the outer tube 22 and the outer wall surface of the inner tube 27 define an air inlet pipe 220, which is connected to the air inlet of the atomizing chamber to allow external air to enter the atomizing chamber. The inner wall surface of the inner tube 27 defines an air outlet pipe 270, which is connected to the air outlet of the atomizing chamber to guide the mist and air mixture in the atomizing chamber out.

[0055] In some embodiments, the housing 21 may be cylindrical, and its outer diameter may be equivalent to the outer diameter of the housing 41. The inner circle of the lower end of the housing 21 extends radially inward to form a neck 211, and the inner diameter of the neck 211 may be equivalent to the inner diameter of the seat body 111 of the base 11. The housing 21 is pressed against the top of the seat body 111 with the neck 211. A sealing ring 15 may also be provided between the bottom of the neck 211 and the top of the seat body 111 to prevent leakage.

[0056] In some embodiments, the outer tube 22 may include a first tube section 221 located at the bottom, a second tube section 222 located in the middle, and a third tube section 223 located at the top. 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 reduced, so 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, so that an annular air intake duct 220 is defined 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 tightly 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 the liquid storage chamber 210. The main body 2511 and two clamping arms 2512 of the liquid absorbing body 251 are arranged in the first pipe section 221, and the extension part 2513 extends upward from the top surface of the main body 2511 and extends into the second pipe section 222. A liquid inlet 2210 is formed on both sides of the top wall of the first pipe section 221, and the two liquid inlets 2210 are respectively arranged corresponding to the two clamping arms 2512 of the liquid absorbing body 251. The side and end surfaces of the clamping arms 2512 absorb liquid, and the main body 2511, the extension part 2513 and the outer tube 22 are sealed and connected, so that the liquid absorbing body can not only block the liquid matrix, but also ensure a good liquid conduction effect. In some embodiments, the distance between the end surfaces of the two clamping arms 2512 is less than the inner diameter of the first pipe section 221, so that a gap is formed between the two clamping arms 2512 and the first pipe section 221, respectively, and the gap can facilitate liquid discharge and liquid absorption, and can also prevent the liquid absorbing body 251 from directly contacting the outer tube 22 for heat conduction.

[0057] In some embodiments, the atomizer body 20 may further include a connector 23 for connecting the atomizer body 20 and the base assembly 10. The connector 23 may be made of metal, such as stainless steel, with its upper end embedded in the outer tube 22, and its lower end extending from the shell 21 and embedded in the base 11, thereby achieving the fixation between the shell 21, the outer tube 22, and the base 11. In some embodiments, the connector 23 may be cylindrical, and may include a cylindrical lower embedded portion 231 located at the lower part and a cylindrical upper embedded portion 232 located at the upper part. The outer diameter of the lower embedded portion 231 is adapted to the aperture of the base hole 1110 on the seat body 111 of the base 11, so as to penetrate the neck 211 of the shell 21 and then be tightly embedded in the seat body 111. The outer diameter of the upper embedded portion 232 is larger than the outer diameter of the lower embedded portion 231 and the inner diameter of the neck 211, and is adapted to the inner diameter of the first pipe section 221 of the outer tube 22, so as to be tightly embedded in the first pipe section 221. An annular retaining wall 233 is formed at the junction of the upper embedded portion 232 and the lower embedded portion 231, and the retaining wall 233 presses against the upper side of the neck 211. In some embodiments, an O-ring 28 may be further provided between the lower side of the retaining wall 233 and the upper side of the neck 211 to prevent leakage.

[0058] In some embodiments, the atomizer body 20 may further include an atomizer seat 24 and a mounting seat 26, and the atomizer assembly 25 is accommodated in a space formed between the atomizer seat 24 and the mounting seat 26. The atomizer seat 24 is disposed below the atomizer assembly 25 and its lower end is embedded in the connecting member 23, the mounting seat 26 at least partially surrounds the upper portion of the atomizer assembly 25, and the lower end of the inner tube 27 is embedded in the mounting seat 26.

[0059] The sensing pipe 13 passes through the atomizer seat 24, the atomizer assembly 25, and the mounting seat 26 from bottom to top, and then extends into the inner tube 27, and is suspended in the inner tube 27 along the longitudinal direction (that is, the air outlet end does not contact the inner wall surface of the inner tube 27). By setting the sensing pipe 13 in the inner tube 27, the inherent space in the structure is fully utilized, the design difficulty of the sensing airway can be reduced, space can be saved, and costs can be reduced. In some embodiments, the upper air outlet end of the sensing pipe 13 is preferably higher than the plane where the top surface of the mounting seat 26 is located to prevent condensate from entering the sensing pipe 13 and causing blockage, and at the same time, it can also prevent condensate from entering the main unit 4 through the sensing pipe 13. The upper air outlet end of the sensing pipe 13 is preferably lower than 2 / 3 of the height of the inner tube 27 from bottom to top to prevent the sensing pipe 13 from being too long and easily tilted, resulting in poor airflow, thereby reducing the sensitivity of the induction.

[0060] In some embodiments, the mounting seat 26 may be made of a soft material such as silica gel, and may include a sleeve portion 261 at the bottom, an embedding portion 262 at the top, and a mounting hole 260 that longitudinally penetrates the sleeve portion 261 and the embedding portion 262. The outer diameter of the sleeve portion 261 is adapted to the inner diameter of the first pipe section 221 so as to be tightly embedded in the first pipe section 221. The top of the sleeve portion 261 may be pressed against the junction of the first pipe section 221 and the second pipe section 222. The outer diameter of the embedding portion 262 is adapted to the inner diameter of the second pipe section 222 so as to be tightly embedded in the second pipe section 222. The mounting hole 260 is respectively connected to the air outlet pipe 270 and the through hole 2510 of the liquid suction 251, so as to connect the through hole 2510 with the air outlet pipe 270.

[0061] The sleeve portion 261 is tightly sleeved outside the main body 2511 of the liquid absorber 251. An opening 2610 is formed on both sides of the top of the sleeve portion 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 then communicated with the liquid storage chamber 210.

[0062] A second air guide groove 2611 extending in the longitudinal direction is respectively provided on two opposite sides of the inner wall surface of the sleeve portion 261, and a first air guide groove 2621 extending in the longitudinal direction is respectively provided on two opposite sides of the outer wall surface of the embedded portion 262. The two first air guide grooves 2621 are respectively arranged correspondingly and communicated with the two second air guide grooves 2611, and the first air guide groove 2621 connects the air intake duct 220 with the second air guide groove 2611. The opening 2610 and the second air guide groove 2611 are staggered in the circumferential direction, which is conducive to liquid suction and air intake.

[0063] The bottom of the embedded portion 262 is pressed against the upper side of the main body 2511. The mounting hole 260 includes a first mounting hole 2622 and a second mounting hole 2623 that penetrate the middle of the embedded portion 262 in the longitudinal direction. The first mounting hole 2622 is located at the lower part of the second mounting hole 2623 and the aperture of the first mounting hole 2622 is larger than the aperture of the second mounting hole 2623. The aperture of the first mounting hole 2622 is adapted to the outer diameter of the extension portion 2513 of the liquid absorbing liquid 251 so that the two can be tightly sleeved together. There is a certain interval between the top of the extension portion 2513 and the bottom 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 tightly embedded in the second mounting hole 2623.

[0064] In some embodiments, the atomizer seat 24 may be made of soft materials such as silica gel, and may include an insertion portion 241 longitudinally embedded in the connector 23 and a flange portion 242 connected to the upper portion of the insertion portion 241. The insertion portion 241 may include a first insertion portion 2411 located at the lower portion and a second insertion portion 2412 located at the upper portion, and the outer diameter of the first insertion portion 2411 is adapted to the inner diameter of the lower embedded portion 231 to be tightly embedded in the lower embedded portion 231. There is a gap between the bottom of the first insertion portion 2411 and the bottom of the base hole 1110 of the base 11, which is conducive to heat insulation. The outer diameter of the second insertion portion 2412 is adapted to the inner diameter of the upper embedded portion 232 to be tightly embedded in the upper embedded portion 232. The flange portion 242 is pressed against the upper side of the upper embedded portion 232, and the outer diameter of the flange portion 242 can be adapted to the inner diameter of the first pipe section 221 so that the two can be tightly sleeved together.

[0065] The main body 2511 of the liquid absorbing body 251 and the sleeve portion 261 of the mounting seat 26 are pressed against the top surface of the flange portion 242, thereby tightly clamping the atomizing assembly 25 between the atomizing seat 24 and the mounting seat 26. The top surface of the flange portion 242 is concave to form a first groove 2401 and second grooves 2402 respectively located on two opposite sides of the first groove 2401. The two second grooves 2402 are respectively arranged correspondingly and connected to the two second air guide grooves 2611, and the first groove 2401 is correspondingly arranged with the liquid absorbing body 251 and connected to the through hole 2510, thereby connecting the second air guide groove 2611 with the through hole 2510.

[0071] The air outlet hole 310 passes through the suction nozzle portion 313, the middle portion 311, and the embedded portion 312 in the longitudinal direction. The air outlet hole 310 may include a first step hole 3101, a second step hole 3102, and a third step hole 3103 arranged in sequence from bottom to top, and the apertures of the first step hole 3101, the second step hole 3102, and the third step hole 3103 are all decreasing. The aperture of the third step 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 step hole 3103.

[0072] The fastener 32 is arranged on the hole wall of the second stepped hole 3102. In some embodiments, the fastener 32 may be cylindrical, and a plurality of reinforcing holes 321 may be provided on the cylindrical side wall thereof. During injection molding, a portion of the suction nozzle 31 may be hot-melted into the reinforcing holes 321, thereby making the combination tighter. In this embodiment, four reinforcing holes 321 are evenly spaced along the circumferential direction 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 tube 22, so that the top of the third pipe section 223 and the fastener 32 are interference-fitted, and the connection is more secure. The top of the third pipe section 223 may abut against the bottom surface of the second stepped hole 3102.

[0073] The third pipe section 223 is sealed with the hole wall of the third stepped hole 3103, and the sealing can usually be performed by setting a sealing ring 33 between the outer side wall of the third pipe section 223 and the hole wall of the third stepped hole 3103. In some embodiments, the sealing ring 33 can be made of a flexible material, such as silicone, which is conducive 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 pressing and positioning the sealing ring 33. In this embodiment, the upper end of the third pipe section 223 is stretched to form two annular retaining walls 2231, and the retaining walls 2231 are spaced apart along the axial direction of the third pipe section 223, and the upper and lower sides of the sealing ring 33 are respectively against the two retaining walls 2231.

[0074] When the electronic atomization device is working, the user inhales from the mouthpiece 313 of the mouthpiece 31, and the negative pressure generated by the inhalation is transmitted to the air switch sensing airway through the air outlet channel of the mist delivery channel. The air switch 46 is turned on, allowing the power supply device 45 to power the atomization component 25 and start atomizing the liquid matrix. At the same time, the outside air enters the atomization chamber through the air inlet channel of the mist delivery channel and mixes with the mist. The mixture of mist and air then enters the user's mouth through the air outlet channel of the mist delivery channel.
