Fig. 1-2 illustrate an electronic atomizing device 1 according to some embodiments of the present utility model, the electronic atomizing device 1 comprising an atomizer 100 and a power supply unit 200 cooperatively connected with the atomizer 100. The power supply device 200 typically includes a battery for powering the atomizer 100, an airflow sensor for sensing changes in airflow, and a control circuit for controlling the heat generation of the atomizer 100. The atomizer 100 is for receiving a liquid substrate and heating the liquid substrate to atomize upon energization to generate an aerosol. In some embodiments, the atomizer 100, the power supply 200 may each be generally cylindrical and both may be mechanically and electrically connected together in an axial direction. Further, the atomizer 100 and the power supply device 200 may be detachably connected together by magnetic connection, screw connection, snap connection, or the like. It will be appreciated that in other embodiments, the atomizer 100 and the power supply means 200 may be connected together in a non-detachable manner. The cross-sectional shape of the atomizer 100 and/or the power supply 200 is not limited to a circular shape, and may have an elliptical shape, a racetrack shape, or a rectangular shape.

A main air passage 33 communicating with the suction port 123 is formed in the inner tube 30, and an auxiliary air passage 23 communicating with the suction port 123 is formed between the inner tube 30 and the outer tube 20. The atomizing assembly 40 is in fluid communication with the reservoir 110 and in fluid communication with the primary air passage 33, and the atomizing assembly 40 is capable of heating and atomizing the liquid matrix from the reservoir 110 after being energized to generate an aerosol, which is then output via the primary air passage 33 to the suction port 123 for inhalation or inhalation by a user. By adding the independent auxiliary air passage 23, when the main air passage 33 is blocked, the air flow can bypass the main air passage 33 and start the air flow sensor through the auxiliary air passage 23 when a user sucks at the suction opening 123; after the atomizing assembly 40 is electrified and heated, the relatively viscous liquid matrix around the atomizing assembly 40 and in the main air passage 33 is heated and diluted, so that the blocking position in the main air passage 33 is dredged, and the normal suction operation of the atomizer 100 is ensured.

In some embodiments, an air intake passage 130 that communicates the main air passage 33 and the auxiliary air passage 23 with the outside may be further formed in the housing 10.

The lower end of the suction nozzle 12 may be inserted into the upper end opening of the liquid storage case 11 to seal and block the upper end of the liquid storage chamber 110. In some embodiments, the mouthpiece 12 may be removably attached to the upper end of the reservoir housing 11, such that the liquid matrix may be added to the reservoir 110 by removing the mouthpiece 12 from the reservoir housing 11, extending the life of the atomizer 100. In other embodiments, the suction nozzle 12 and the liquid storage shell 11 may be connected together in a non-detachable manner, or the suction nozzle 12 and the liquid storage shell 11 may be an integrally formed structure.

An air outlet hole 120 is formed in the suction nozzle 12 in a penetrating manner along the longitudinal direction, and a suction port 123 is formed at the upper end outlet of the air outlet hole 120. The gas outlet aperture 120 may include a first aperture segment 121 and a second aperture segment 122 that are sequentially in communication from bottom to top in an axial direction. The upper ends of the outer tube 20, the inner tube 30 may be received in the first bore section 121. The cross-sectional area of the first bore section 121 is larger than the cross-sectional area of the second bore section 122 such that a step surface 1211 is formed at the junction of the first bore section 121 and the second bore section 122.

The outer tube 20 and the inner tube 30 may be circular tubes and may be disposed coaxially with the liquid storage case 11. It will be appreciated that in other embodiments, the reservoir housing 11 and/or the outer tube 20 and/or the inner tube 30 are not limited to being circular tubular, but may be oval tubular, square tubular, or the like. The outer tube 20 is longitudinally disposed in the liquid storage shell 11, and an annular liquid storage cavity 110 is formed between the outer wall surface of the outer tube 20 and the inner wall surface of the liquid storage shell 11. The auxiliary air passage 23 is formed between the inner wall surface of the outer tube 20 and the inner wall surface of the inner tube 30.

The outer tube 20 and the inner tube 30 are respectively provided with at least one first liquid inlet 210 and at least one second liquid inlet 3120 correspondingly, so as to communicate the liquid storage cavity 110 with the atomizing assembly 40.

In some embodiments, the outer tube 20 may include a first outer tube segment 21 and a second outer tube segment 22 connected in sequence from bottom to top in an axial direction, the first outer tube segment 21 having an outer diameter and an inner diameter that are greater than the outer diameter and the inner diameter of the second outer tube segment 22, respectively. The inner tube 30 may include a first inner tube section 31 and a second inner tube section 32 connected in sequence from bottom to top in the axial direction, the first inner tube section 31 having an outer diameter and an inner diameter greater than the second inner tube section 32, respectively. The first inner tube section 31 is disposed in the first outer tube section 21, the second inner tube section 32 is disposed in the second outer tube section 22, and the atomizing assembly 40 is receivable in the first inner tube section 31. The outer tube 20 and the inner tube 30 have a stepped structure, and have a larger lower end and a smaller upper end, so that a larger liquid storage space is provided in the liquid storage cavity 110 formed between the outer tube 20 and the liquid storage shell 11.

The second inner tube section 32 may have an outer diameter smaller than an inner diameter of the second outer tube section 22 such that an annular air flow passage 320 is formed between the outer wall surface of the second inner tube section 32 and the inner wall surface of the second outer tube section 22, the air flow passage 320 being operable to form a portion of the auxiliary air passage 23. The outer wall surface of the first inner pipe section 31 may be concavely formed with at least one air guide groove 310, and an upper end of the at least one air guide groove 310 communicates with a lower end of the air flow channel 320 to form the auxiliary air passage 23. In the present embodiment, two air guide grooves 310 are symmetrically disposed on two radial sides of the first inner pipe section 31, and each air guide groove 310 is a linear channel extending from the lower end of the first inner pipe section 31 to the upper end thereof in the longitudinal direction. It is understood that in other embodiments, the number of air guide slots 310 may be one or more than two, and the air guide slots 310 may be non-linear channels.

It will be appreciated that in other embodiments, the secondary air channel 23 is not limited to the above-described formation. For example, the air guide groove 310 may extend from the lower end of the first inner pipe section 31 up to the upper end of the second inner pipe section 32, at which time the outer diameter of the second inner pipe section 32 may also be equal to the inner diameter of the second outer pipe section 22. For another example, the air guide groove 310 may be formed on the inner wall surface of the outer tube 20, or may be formed on both the inner wall surface of the outer tube 20 and the outer wall surface of the inner tube 30.

The outer tube 20 may further be provided with at least one pressure relief hole 220, where the at least one pressure relief hole 220 communicates the liquid storage cavity 110 with the outside, so as to balance the pressure in the liquid storage cavity 110, so as to make the liquid discharge smooth. The pressure release hole 220 may be located at a position higher than the upper end surface of the liquid storage cavity 110, so as to reduce leakage of the liquid matrix in the liquid storage cavity 110 from the pressure release hole 220. In this embodiment, the pressure relief holes 220 are formed in the second outer pipe section 22 and are in communication with the airflow channels 320, and the pressure relief holes 220 may be multiple and uniformly spaced along the circumference of the second outer pipe section 22.

The upper ends of the second inner tube section 32, the second outer tube section 22 may extend into the first bore section 121. The outer wall surface of the second outer tube section 22 is in sealing engagement with the wall surface of the first bore section 121 to avoid leakage of the liquid matrix in the reservoir 110. A gap is formed between the upper end surface of the second inner tube section 32 and the step surface 1211 to form a communication passage 1210 that communicates the auxiliary air passage 23 with the second hole section 122. It will be appreciated that, in other embodiments, the communication between the auxiliary air channel 23 and the second hole section 122 may be achieved in other manners, for example, a communication port may be formed at or near the upper end of the second inner pipe section 32 to communicate the auxiliary air channel 23 with the second hole section 122; for another example, the communication between the auxiliary air passage 23 and the second hole section 122 may be achieved by setting the outer diameter of the upper end of the second inner pipe section 32 smaller than the hole diameter of the second hole section 122.

Further, in some embodiments, the first inner tube segment 31 may include a first portion 311 and a second portion 312 coupled to an upper end of the first portion 311. The first portion 311 and the second portion 312 may have the same inner diameter. The outer diameter of the second portion 312 is the same as the inner diameter of the first outer tube section 21 to achieve a fixation of the inner tube 30 in the outer tube 20. The atomizing assembly 40 is accommodated in the second portion 312, and accordingly, the second liquid inlet 3120 is opened on the wall of the second portion 312. In the present embodiment, there are two second liquid inlets 3120, and the two second liquid inlets 3120 are symmetrically disposed at two radial sides of the second portion 312, respectively. Accordingly, there are two first liquid inlets 210, and the two first liquid inlets 210 are respectively corresponding to and communicated with the two second liquid inlets 3120.

The outer diameter of the first portion 311 is slightly smaller than the outer diameter of the second portion 312 and smaller than the inner diameter of the first outer tube section 21. The clearance fit between the outer wall surface of the first portion 311 and the inner wall surface of the first outer pipe section 21 reduces the force required to insert the inner pipe 30 into the outer pipe 20, and also allows an annular vent gap 3110 to be formed between the outer wall surface of the first portion 311 and the inner wall surface of the first outer pipe section 21, the vent gap 3110 being usable to form part of the auxiliary air passage 23. It should be understood that, based on the structure of the first inner pipe section 31, the air guide groove 310 may be formed only on the second portion 312 of the first inner pipe section 31, so that the lower end of the air guide groove 310 is in communication with the upper end of the ventilation gap 3110. In other embodiments, the outer diameter of the first portion 311 may also be equal to the outer diameter of the second portion 312.

The atomizing assembly 40 may include a liquid absorbing body 41 and a heat generating body 42 in contact with the liquid absorbing body 41. The liquid sucking device 41 is used for sucking the liquid matrix from the liquid storage cavity 110 and conducting the liquid matrix to the heating body 42, and the heating body 42 is used for heating and atomizing the liquid matrix after being electrified. In this embodiment, the liquid suction 41 is a porous ceramic that is capable of sucking the liquid matrix from the liquid storage chamber 110 by the infiltration and capillary effect of its internal microporous structure. It will be appreciated that in other embodiments, the liquid absorbent 41 is not limited to porous ceramic materials, and may be made of other porous materials such as liquid absorbent cotton.

The heating element 42 may be a heating film, which may be formed on the blank of the liquid absorbing body 41 by silk-screen printing, printing or spraying, and then sintered together with the liquid absorbing body 41; alternatively, the heating element 42 may be a metal heating sheet or a metal heating wire formed separately.

In some embodiments, atomizing assembly 40 may also include a liquid guide 43. The liquid guide 43 may be made of a liquid guide cotton material, and may be cylindrical and sleeved between the outer wall surface of the liquid suction body 41 and the inner wall surface of the inner tube 30, so as to quickly and uniformly guide the liquid matrix in the liquid storage cavity 110 to the liquid suction body 41. It will be appreciated that in other embodiments, the liquid guide 43 is not limited to liquid guide cotton material, and may be made of porous ceramics or other porous materials.

The lower outer wall surface of the first outer tube section 21 may be sealingly engaged with the wall surface of the first mounting hole 1320 to prevent leakage of the liquid matrix in the liquid reservoir 110.

The bottom of the first mounting hole 1320 has a supporting surface 1321, and the lower end surfaces of the first inner pipe section 31 and the first outer pipe section 21 can abut against the supporting surface 1321 to achieve positioning of the first inner pipe section 31 and the first outer pipe section 21 in the first mounting hole 1320. The first inner pipe section 31 may further be formed with at least one vent 313 communicating the auxiliary air passage 23 with the air intake passage 130. In the present embodiment, two air ports 313 are symmetrically disposed on two radial sides of the first inner pipe section 31, and each air port 313 is formed by upwardly recessing the lower end surface of the first inner pipe section 31. It will be appreciated that in other embodiments, the number of vents 313 is not limited to two, and may be one or more than two; in addition, the vent 313 may be disposed at other locations on the first inner tube segment 31, for example, it may also be disposed near the lower end of the first inner tube segment 31.

In some embodiments, the base 13 may include a base 131, a fitting portion 132 extending upward from an upper end surface of the base 131, and a docking portion 133 extending downward from a lower end surface of the base 131. The embedded part 132 may be cylindrical and embedded in the lower part of the liquid storage shell 11, and at least part of the outer peripheral surface of the embedded part 132 is in sealing fit with the inner wall surface of the liquid storage shell 11 so as to seal and block the lower end of the liquid storage cavity 110. The base 131 may be cylindrical, an upper end surface of the base 131 may abut against a lower end surface of the liquid storage case 11, and an outer diameter of the base 131 may be identical to an outer diameter of a lower end of the liquid storage case 11.

The lower outer wall surface of the docking portion 133 may be provided with a screw structure for screw-coupling with the power supply device 200. The at least one air intake hole 1331 may be provided on a sidewall of the docking portion 133, which is not provided with a screw structure, at an upper portion thereof. In the present embodiment, there are two air intake holes 1331, and the two air intake holes 1331 are symmetrically disposed on two radial sides of the abutting portion 133.

The bottom surface of the abutting portion 133 may be further upwardly recessed with a second mounting hole 1330 communicating with the lower end of the first mounting hole 1320. The second mounting hole 1330 has a smaller aperture than the first mounting hole 1320 such that the junction between the second mounting hole 1330 and the first mounting hole 1320 forms an annular support surface 1321.

An electrode post 16 may also be disposed longitudinally in the first mounting hole 1320. The heating element 42 is electrically connected to the electrode column 16, and further electrically connected to the power supply device 200 via the electrode column 16. In some embodiments, the base 13 may be made of a conductive material such as metal, and the electrode post 16 is disposed in the first mounting hole 1320 and electrically insulated from the base 13, and two electrodes of the heating element 42 are electrically connected to the electrode post 16 and the base 13, respectively. Generally, an insulating sleeve 15 may be sleeved between the outer wall surface of the electrode column 16 and the hole wall surface of the first mounting hole 1320 to ensure an insulating and sealing connection between the electrode column 16 and the base 13. The insulating sleeve 15 may be made of an insulating material such as silica gel or plastic. It will be appreciated that in other embodiments, the base 13 may be made of an insulating material such as plastic.

In the present embodiment, the electrode column 16 has a hollow cylindrical shape, in which a through hole 161 is formed in the longitudinal direction, and the through hole 161 can be used to construct the intake passage 130. It will be appreciated that when the through hole 161 is used for air intake, the air intake hole 1331 may not be provided on the base 13.

The upper end of the electrode column 16 is spaced from the lower end of the atomizing assembly 40 to facilitate thermal insulation. The two electrodes of the heating element 42 can be electrically connected to the electrode post 16 and the base 13 via the first electrode lead 44 and the second electrode lead 45, respectively.

In the present embodiment, the heat insulating space 1310 is an annular groove formed by recessing the outer circumferential surface of the base 131 radially inward. Since the outer diameter of the base 131 is maximized, the heat insulation space 1310 is provided on the base 131, so that the heat insulation space 1310 has a large volume, the heat insulation effect is improved, the heat transferred to the butt joint part 133 can be reduced, and the heat transferred to the power supply device 200 can be reduced.

It is understood that in other embodiments, insulating space 1310 may take other shapes as well. For example, the insulating space 1310 may include a plurality of spaced apart insulating slots, which may be spaced apart circumferentially and/or axially along the base 13. In other embodiments, the heat insulation space 1310 may be formed entirely or partially on the embedded portion 132 or the abutting portion 133. In addition, the heat insulation space 1310 may be filled with a heat insulation medium to further improve the heat insulation effect.
