Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

Referring to fig. 1 and fig. 2, two schematic perspective assembly views of an atomizer 200 according to an embodiment of the present invention are shown. The atomizer 200 may have a liquid substrate stored therein for heating vaporization of the liquid substrate to generate an aerosol when energized. The atomizer 200 may be combined with a power supply assembly for powering it to form an electronic atomizer device that can be used directly by a user. The liquid matrix can be liquid such as tobacco tar, medicinal liquid, etc.; herein, liquid substrates may also be referred to as liquids, vaporization may also be referred to as atomization, and aerosols may also be referred to as smoke, aerosol, or mist.

Reference is now made to fig. 3-6, which are two schematic cross-sectional and two schematic perspective exploded views of the atomizer 200 of fig. 1. Atomizer 200 may include atomizing core assembly 100 and main housing 90. The main housing 90 defines a liquid receiving space 91 and has an aerosol passage within the main housing 90 for fluid communication with the atomizing core assembly 100 and for outputting the generated aerosol to the outside. For example, the aerosol passage may be defined by a smoke output duct 92, said smoke output duct 92 having a free end 93. The main housing 90 is generally configured as a hollow cylinder and has an air intake port 94 at a proximal end; which has an opening at the distal end to facilitate assembly of the various functional components within the main housing 90 through the opening. Atomizing core assembly 100 is cooperatively mounted with main housing 90 for receiving liquid matrix from liquid receiving space 91.

Reference is now made to fig. 7 and 8, which are two exploded perspective views of the atomizing core assembly 100 of the atomizer 200. In some embodiments, as shown in conjunction with fig. 3, 7, and 8, atomizing core assembly 100 may include a liquid directing element 10, a heating element 20, and a first support 30. The liquid guide element 10 comprises an atomizing surface 11 and a liquid suction surface 12. The heating element 20 may be arranged on the atomizing surface 11 and is configured to heat at least a portion of the liquid substrate absorbed by the liquid guiding element 10 to generate an aerosol. The first bracket 30 includes a partition 31, a first chamber 32 having an upper opening 33, and a second chamber 34 having a lower opening 35. The partition 31 partitions the first chamber 32 and the second chamber 34, and the partition 31 includes a first through hole 36 communicating the first chamber 32 and the second chamber 34. Wherein the liquid guiding element 10 is at least partially accommodated in the second chamber 34, and the atomizing surface 11 faces the first chamber 32. The atomizing surface 11 is used for the aerosol to escape and enter the first chamber 32 through the first through hole 36. For example, the first chamber 32 may be in communication with a smoke output duct 92 of the atomizer 200 for discharging the generated aerosol via the smoke output duct 92. The liquid-guiding element 10 may be entirely contained in the second chamber 34, or may be arranged such that a portion of the atomizing surface 11 is located in the first through-hole 36, or even in the first chamber 32.

The liquid guiding element 10 can be made of a material having capillary channels or pores, for example, a hard or rigid capillary structure such as cellucotton, a porous ceramic body, a glass fiber rope, a porous glass ceramic, and a porous glass. The liquid guiding member 10 is in fluid communication with the liquid containing space 91 to suck the liquid substrate transferred from the liquid containing space 91. The atomizing surface 11 of the liquid guiding member 10 may be an upper surface thereof facing the flue gas output duct 92, which is preferably a plane extending along the cross section of the main housing 90. The liquid suction surface 12 may be disposed opposite the atomization surface 11.

The heating element 20 may be in the form of resistance heating, and aerosol generated by heating at least part of the liquid substrate absorbed by the liquid guiding element 10 may be released into the smoke output duct 92 after escaping from the atomizing surface 11. For example, the heating element 20 may be formed on the atomizing surface 11 of the liquid guiding element 10 by mounting, printing, depositing, or the like. The heating element 20 may be made of stainless steel, nichrome, ferrochromium alloy, titanium metal, etc. in some embodiments. As shown in fig. 7, the heating element 20 is a meandering, circuitous, etc. patterned electrically conductive track and may comprise electrically conductive terminals 21 at both ends; the conductive terminals 21 may be in the form of pads, which may have a square, circular, oval, or the like shape.

In other embodiments, the heating element 20 may also be in the form of an electromagnetic induction element, or infrared radiation non-contact heating. In addition to the possibility of integrating the heating element 20 in the form of a resistance wire or a stainless steel sheet on the atomization surface, the heating element 20 may also be at least partially embedded in the liquid-conducting element 10, for example at least partially embedded in the liquid-conducting element 10 at a location close to the atomization surface 11.

In the atomizer 200 of this embodiment, by providing the first bracket 30 including the partition 31, the first chamber 32 having the upper opening 33, and the second chamber 34 having the lower opening 35, it is facilitated to place the liquid guiding member 10 in the second chamber 34 via the lower opening 35 from bottom to top; in the first bracket 30 having such a structure, the mold can easily release the molded first bracket 30, so that the complexity of the mold for molding the first bracket 30 can be reduced, and the mass productivity of the first bracket 30 can be improved.

In addition, by arranging the atomizing surface 11 of the liquid guiding element 10 to face the smoke output pipeline 92, so that the atomizing surface 11 faces the air suction port 94, the heating element 20 on the atomizing surface 11 generates heat, so that the liquid on the atomizing surface 11 absorbs the heat and atomizes the generated smoke, does not need to pass through the liquid guiding element 10 per se, but directly enters the air suction channel of the smoke output pipeline 92 until reaching the air suction port 94 to be sucked by a user, thereby reducing the loss generated when the smoke passes through the atomizing core per se, ensuring that enough smoke is effectively absorbed by the user in unit time, and improving the effective smoke amount generated by the electronic atomizing device in unit time. In addition, the distance from the atomizing surface 11 to the air inlet 94 is relatively small, so that the path through which the smoke flows to the air inlet 94 is shortest, the loss of the smoke in the air suction channel can be reduced, and the effective smoke amount generated by the electronic atomizing device in unit time is further ensured.

In some embodiments, as shown in connection with fig. 3 and 7, a portion of the atomizing surface 11 is exposed to the first chamber 32 through the first through hole 36 of the partition 31. For example, the atomizing surface 11 may be arranged opposite to the first through hole 36, such that the partition 31 corresponds to an edge portion of the atomizing surface 11, and the first through hole 36 exposes most of the other surface of the atomizing surface 11, i.e., most of the surface of the atomizing surface 11 can be seen from the first chamber 32. In this way, the aerosol generated at the nebulizing surface 11 is enabled to be discharged via the first through holes 36 and the first chamber 32 towards the smoke output duct 92.

In some embodiments, as shown in connection with fig. 3 and 7, the heating element 20 is disposed on the portion of the atomization surface 11 that is exposed. In this way, aerosol generated at the nebulizing surface 11 can be made able to discharge directly via the first through holes 36 to the first chamber 32.

In some embodiments, as shown in fig. 3 and 7, the first support 30 further comprises a lower fluid passage 37, wherein the lower fluid passage 37 extends downward from the upper end of the first support 30 and laterally communicates with the second chamber 34, thereby enabling the fluid medium to flow to the liquid-absorbing surface 12 of the liquid-guiding member 10. The lower liquid channel 37 is adapted to communicate at an upper end with the liquid receiving space 91 and at a lower end with the second chamber 34. For example, the lower liquid passage 37 may be formed with a side opening 37A at a lower end adjacent to a side of the second chamber 34 so as to be able to communicate with the second chamber 34. The side opening 37A may be disposed vertically or obliquely with respect to the atomizing surface 11. In this way, the liquid matrix transported downwards through the downcomer 37 can flow in a transverse direction through the side opening 37A to the second chamber 34, in particular to the suction side 12 of the liquid-conducting element 10 in the second chamber 34.

In the above embodiment, by providing the lower liquid channel 37, for example, the liquid of the tobacco juice can enter the liquid guiding element 10 through the lower liquid channel 37, and is guided upwards to the atomizing surface 11 of the liquid guiding element 10 by capillary phenomenon for atomization, the atomization amount of the tobacco juice is completely supplied by capillary phenomenon, the liquid does not leak downwards in the middle process, and the liquid leakage prevention effect is good.

In some embodiments, as shown in fig. 3 and 7, the atomizing cartridge 200 further includes a first sealing member 40, at least a portion of the first sealing member 40 is located between the liquid guiding member 10 and the inner wall 34A of the second chamber 34, and is used for sealing the atomizing surface 11 and the liquid suction surface 12. That is, the first sealing member 40 is used to enable the liquid provided by the liquid accommodating space 91 to enter the liquid guiding member 10 only through the liquid suction surface 12 and then to be delivered to the atomizing surface 11. The first seal 40 may be generally cup-shaped such that the fluid conducting member 10 may be received within a recess of the cup-shaped first seal 40. The first sealing member 40 is further provided with liquid inlets 44 on the left and right side walls thereof, so that the liquid suction surface 12 is communicated with the outside through the liquid inlets 44, and further communicated with the liquid accommodating space 91 when assembled. The first sealing member 40 may be made of a sealing silicone material.

In some embodiments, as shown in conjunction with fig. 3 and 8, the inner wall 34A of the second chamber 34 includes a first ramp 34B that is inclined relative to the longitudinal direction. The first sealing element 40 comprises a second inclined surface 41, and the first inclined surface 34B is fit with the second inclined surface 41. For example, the second chamber 34 may have a flared shape by extending the left and right sides of the second chamber 34 away from the liquid guiding member 10. In addition, the opening at the bottom of the second chamber 34 may have a uniform cross-sectional area. The outer profile of the first seal 40 may be substantially complementary to the shape of the second chamber 34 for sealing engagement. Thus, by providing the first inclined surface 34B and the second inclined surface 41, the first sealing member 40 accommodating the liquid guiding element 10 can be conveniently placed in the second chamber 34, and the sealing between the liquid guiding element 10 and the first bracket 30 can be enhanced; in addition, by providing the side opening 37A on the first slope 34B, the first bracket 30 can be easily released in the vertical stroke during manufacturing.

In some embodiments, as shown in connection with fig. 3 and 7, the first seal 40 includes a first portion 42, the first portion 42 covers the edge portion 13 of the atomization surface 11, and the first portion 42 abuts against the partition 31. In this way, the drainage element 10 can be fixedly held within the first seal 40; further, when the liquid guiding member 10 is mounted, the first portion 42 of the first seal member 40 abuts against the partition portion 31, thereby preventing the liquid guiding member 10 from being directly and rigidly contacted with the first holder 30.

In some embodiments, as shown in fig. 3 and 7, the liquid guiding element 10 has a channel 14 extending through the liquid guiding element 10, and at least a portion of an inner surface of the liquid guiding element 10 defining the channel 14 forms the suction surface 12. For example, the fluid-guiding member 10 may be a square tube having a left and right through passage 14. The whole liquid guide element 10 can be square, and a left-right through channel 14 is formed in the liquid guide element; thus, the top surface of the liquid guiding member 10 can serve as the atomizing surface 11, and the upper surface of the passage 14 can serve as the liquid absorbing surface 12; in addition, the left and right surfaces and the lower surface of the passage 14 can also serve as the liquid suction surface. The two ends of the channel 14 are open to the inlet ports 44 at the left and right ends of the first sealing member 40, and the two inlet ports 44 are open to the two side openings 37A of the first bracket 30. In this way, the liquid substrate can be transported into the liquid guiding element 10 simultaneously on both the left and right sides.

In some embodiments, as shown in conjunction with fig. 3, 7, and 8, the cross-sectional area of the first chamber 32 may be configured to be smaller than the cross-sectional area of the second chamber 34. For example, the length of the first chamber 32 may be less than the length of the second chamber 34 in the direction of the length of the atomizing surface 11; at this time, the thickness of the partition wall between the lower liquid passage 37 and the first chamber 32 may be thicker than the thickness of the partition wall between the lower liquid passage 37 and the second chamber 34; the length direction may be parallel to the direction of extension of the channel 14. Alternatively or additionally, the length of the first chamber 32 may be smaller than the length of the second chamber 34 in the width direction of the atomizing surface 11. In this way, the distance between the wall surface of the first chamber 32 and the smoke output pipeline 92 can be reduced as much as possible, and the effect of reducing the retention of the continuously generated aerosol in the first chamber 32 is achieved; accordingly, the user can obtain a better mouth feel of the smoke.

In some embodiments, as shown in conjunction with fig. 3, 7, and 8, the atomizer 200 includes a second seal 50. The second seal 50 includes an inner cylindrical portion 51 and an outer cylindrical portion 52, and the inner cylindrical portion 51 is inserted into the first chamber 32 and is fitted to the inner wall 32A of the first chamber 32. The outer tubular portion 52 surrounds the upper end of the first bracket 30 and fits snugly against the outer wall of the upper end. The second seal 50 may further comprise a top through hole 54 and a top receptacle 55, wherein the top through hole 54 is for communicating the liquid receiving space 91 with the lower liquid channel 37, and the top receptacle 55 is for inserting the free end 93 of the flue gas outlet duct 92 therein. By providing the second sealing member 50, a seal can be formed between the first holder 30 and the main housing 90, so that the liquid medium in the liquid-receiving space 91 can be transported to the liquid-absorbing surface 12 only through the lower liquid passage 37.

In some embodiments, as shown in fig. 3 and 8, the inner cylinder 51 is further provided with a blocking arm 53 extending toward the atomizing surface 11 and adjacent to the atomizing surface 11. The blocking arm 53 may be used to reduce the entrapment of the generated aerosol between the blocking arm 53 and the inner wall 32A of the first chamber 32. The blocking arm 53 may extend into the first through hole 36. By providing the blocking arm 53, a space between the blocking arm 53 and the inner wall 32A of the first chamber 32 is small, and the air flow tends not to circulate; therefore, the aerosol generated on the atomizing surface 11 basically does not flow into the space between the blocking arm 53 and the inner wall 32A, and the effect of reducing the retention of the continuously generated aerosol in the space is achieved; accordingly, the user can obtain a better mouth feel of the smoke.

In some embodiments, as shown in connection with fig. 3 and 7, the heat generating portion of the heating element 20 is located between two blocking arms 53. The heat generating portion of the heating element 20 comprises a wire between two electrically conductive terminals 21. In this way, aerosol can be generated directly in the space between the two blocking arms 53 and can be discharged directly into the smoke outlet duct 92.

In some embodiments, as shown in fig. 3, 7 and 8, the first support 30 includes a sidewall 30A and a second chamber 34 having a lower opening 35, and the sidewall 30A has an electrode through hole 30B. The atomizing core assembly 100 may further include a first electrode elastic sheet 60, where the first electrode elastic sheet 60 includes a first bending portion 61, a connecting portion 62, and a second bending portion 63 connected in sequence, and both the first bending portion 61 and the second bending portion 63 are disposed in a bending manner with respect to the connecting portion 62. After the liquid guiding element 10 is accommodated in the second chamber 34, the first bent portion 61 can pass through the electrode through hole 30B and enter the second chamber 34, and the second bent portion 63 can be located at one side of the liquid guiding element 10 and used for providing support for the liquid guiding element 10 so that the liquid guiding element 10 is held in the accommodating chamber 34. It is easy to understand that after the first bending portion 61 passes through the electrode through hole 30B and enters the second chamber 34, the first electrode elastic piece 60 is inserted into the first bracket 30; further, when the liquid guiding element 10 is supported by the second bending portion 63, the liquid guiding element 10 can be suspended in the second chamber 34 by the first electrode elastic piece 60. The first electrode elastic sheet 60 may be formed by bending a sheet-shaped metal substrate.

In other embodiments, the electrode vias 30B may not be formed in the sidewalls 30A; instead, the first electrode elastic piece 60 and the first support 30 may be installed in other manners as long as at least a portion of the first bending portion 61 extends into the second cavity 34 to contact with the heating element 20. For example, a recess may be formed from the top of the first bracket 30 for the first bending portion 61 to pass through and enter the second cavity 34; alternatively, the first bend 61 may be routed around the top end of the first bracket 30 and into the second chamber 34.

In some embodiments, as shown in fig. 7 and 8, the free end 64 of the first bent portion 61 can press against the heating element 20. The free end 64 of the first bending portion 61 can be used as a conductive contact, so as to be pressed against the conductive terminal 21 of the heating element 20 by the elasticity of the first electrode elastic piece 60. The number of the first electrode dome 60 may be two, so that the two free ends 64 are respectively in conductive contact with the two conductive terminals 21 of the heating element 20, thereby realizing the current transmission.

In some embodiments, as shown in fig. 7 and 8, at least a portion of the second bent portion 63 has a width greater than that of the connecting portion 62. In this way, the support stability of the second bent portion 63 can be improved.

In some embodiments, referring to fig. 3, 5, 9 and 10, fig. 9 and 10 are two exploded perspective views of the second holder 70 and the second electrode dome 80 of the atomizer 200 shown in fig. 5; the atomizing core assembly 100 includes a second bracket 70, and the first bracket 30 is mounted on the second bracket 70. The second support 70 is provided with a second electrode elastic sheet 80, and the first electrode elastic sheet 60 is electrically connected with the second electrode elastic sheet 80. For example, the first bracket 30 may be provided with two opposite outer sides thereof with locking blocks, and the second bracket 70 may be provided with two opposite inner sides thereof with locking grooves, so that the two brackets can be connected by snapping. The second electrode elastic piece 80 and the second support 70 may be injection molded to form an integral structure, and a portion of the second electrode elastic piece 80 is exposed out of the second support 70 so as to be in conductive contact with, for example, the second bent portion 63 of the first electrode elastic piece 60. The second electrode elastic sheet 80 may be formed by bending a sheet-shaped metal substrate.

In some embodiments, as shown in fig. 3, 8, 9 and 10, the second bent portion 63 includes a horizontal portion 65 and a downward extending portion 66, the horizontal portion 65 provides, for example, an upward supporting force for the liquid guiding element 10, and the downward extending portion 66 is in contact with the second electrode elastic piece 80 on the second bracket 70. In this way, it is facilitated that the electrically conductive connection between the components is achieved by elastic contact after the assembly is completed.

In some embodiments, as shown in fig. 3, 6, 9 and 10 in combination, a portion 81 of the second electrode dome 80 is exposed outwardly from a side of the second support 70 for electrically conductive contact with a power supply component of an electronic atomizer device. For example, a portion 81 of the second electrode tab 80 may be disposed in a vertical orientation and exposed laterally of the second bracket 70 to facilitate conductive contact with the electrically conductive resilient terminals of the power module. The number of the second electrode tabs 80 may be two, and may be respectively disposed at left and right sides of the second support 70, and such that the exposed two portions 81 are disposed parallel to each other.

In some embodiments, as shown in fig. 3 and 9, the number of the first electrode tabs 60 is two; the second bracket 70 includes a spacer 73, and the two first electrode tabs 60 are spaced apart by the spacer 73. For example, the spacing portion 73 may extend upward from the bottom in the second support 70 and be located between the second bending portions 63 of the two first electrode elastic pieces 60. In this way, when the first electrode elastic pieces 60 and the first support 30 are mounted on the second support 70, a short circuit caused by contact of the two first electrode elastic pieces 60 can be prevented.

In some embodiments, as shown in fig. 3, 6, 9 and 10, the first sealing element 40 further includes a sealing bottom 43 covering a part of the surface of the liquid guiding element 10, and the second bent portion 63 presses against the sealing bottom 43. The sealing bottom 43 may be in the shape of a shallow container to receive the bottom of the liquid guiding member 10, thereby preventing the liquid from leaking downward through the liquid guiding member 10. By means of the elastic force of the first electrode elastic piece 60, the second bending portion 63 is pressed against the sealing bottom portion 43, so that the liquid guiding element 10 is clamped between the first bending portion 61 and the second bending portion 63 of the first electrode elastic piece 60.

In some embodiments, as shown in fig. 3, 9 and 10, the second bracket 70 may be provided with an air inlet 71, and the air inlet 71 is communicated with the inner space 72 of the second bracket 70. As shown in fig. 7 and 8, the side wall 30A of the first bracket 30 may be provided with a vent hole 30C, and the vent hole 30C communicates between the outside of the first bracket 30 and, for example, the internal space of the second chamber 34. Thus, when the first bracket 30 is mounted in the second bracket 70, the inner space 72 of the second bracket 70 can communicate with the inner space of the first bracket 30 through the vent hole 30C.

In an embodiment, as shown in conjunction with fig. 3 and 8, the atomizer 200 may further include a main housing 90. Wherein the first support 30 is coupled to the main housing 90 such that the aerosol passage of the main housing 90 is in fluid communication with the first chamber 32. For example, the free end 93 of the flue gas outlet duct 92 of the main housing 90 may be inserted into the first chamber 32. In this way, the atomizing core assembly 100 may be provided with the liquid substrate to be atomized through the liquid receiving space 91 defined by the main housing 90, and the generated aerosol may be delivered to the exterior of the atomizer 200 through the smoke output duct 92 for inhalation by a user.

In an embodiment, similar to the blocking arm 53 shown in fig. 8, the free end 93 of the flue gas outlet duct 92 may also be provided with a blocking arm extending towards the atomizing surface 11. The blocking arm may be used to reduce entrapment of the generated aerosol between the blocking arm and the inner wall 32A of the first chamber 32. The blocking arm extends into the first through hole 36. In this embodiment, the second seal 50 may not be provided with the blocking arm 53.

As shown in fig. 1 and 2, a sealing plug 95 can be inserted into the air inlet 94 of the atomizer 200, and a sealing sheet 96 can be attached to the air inlet 71 of the second bracket 70, so as to maintain the sealing before the atomizer 200 is used for the first time, and prevent the liquid from leaking to the outside.

The various components of the atomizer 200 of the present invention have been described above. When the electronic atomization device is needed for suction, the atomizer 200 and the power supply assembly are installed and connected, and then the power supply switch of the power supply assembly is turned on, so that the power supply assembly supplies power to the atomizer 200; then, when the user inhales the suction nozzle portion where the air suction port 94 of the atomizer 200 is located, the atomizer 200 may be started to operate according to the air suction action by the controller of the electronic atomization device, and finally, the aerosol for the user to inhale is generated. Wherein, the liquid from the liquid containing space 91 is heated and atomized by the heating element 20 to form a mist, and the outside air can flow through the air inlet 71, the inner space 72 of the second bracket 70 and the vent hole 30C of the first bracket 30 in sequence, and then is conveyed to the upper part of the atomizing surface 11 of the liquid guiding element 10 in the first bracket 30, so as to carry the formed mist out of the smoke output pipeline 92.
