Description
Technical Field
The embodiment of the application relates to the technical field of electronic atomization devices, in particular to an atomizer and an electronic atomization device.
Background
Smoking articles (e.g., cigarettes, cigars, etc.) burn tobacco during use to produce tobacco smoke. Attempts have been made to replace these tobacco-burning products by making products that release compounds without burning.

One embodiment of the present invention proposes an electronic atomization device 300, the configuration of which is shown in fig. 1, and which includes: a nebulizer 100 in which a liquid substrate is stored and vaporized to generate an aerosol; and a power supply assembly 200 for powering the nebulizer 100. 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.
In an alternative embodiment, such as shown in fig. 1, the power module 200 includes a receiving cavity 270 disposed at one end in the longitudinal direction for receiving and housing at least a portion of the atomizer 100, and a first electrical contact 230 at least partially exposed at a bottom inner surface of the receiving cavity 270 for making an electrical connection with the atomizer 100 when at least a portion of the atomizer 100 is received and housed in the power module 200 to supply power to the atomizer 100.
According to the preferred embodiment shown in fig. 1, the atomizer 100 is provided with a second electrical contact 64 on the end opposite the power supply assembly 200 in the longitudinal direction, such that when at least a portion of the atomizer 100 is received in the receiving chamber 270, the second electrical contact 64 is brought into electrical conduction by contact against the first electrical contact 230.
The power module 200 may be provided with a sealing member 260 therein, and the above receiving chamber 270 may be formed by dividing at least a part of the inner space of the power module 200 by the sealing member 260. In the preferred embodiment shown in fig. 1, the seal 260 is configured to extend across the cross-section of the power module 200 and is made of a flexible material to prevent liquid medium that seeps from the atomizer 100 to the receiving chamber 270 from flowing to the controller 220, sensor 250, etc. inside the power module 200.
In the preferred embodiment shown in fig. 1, the power supply module 200 may further include an electric core 210 near the other end opposite to the receiving cavity 270 in the longitudinal direction for supplying power; and a controller 220 disposed between the cell 210 and the housing cavity, the controller 220 operable to direct electrical current between the cell 210 and the first electrical contact 230.
The power module 200 may further include a sensor 250 for sensing a suction airflow generated by the nebulizer 100 during suction, and the controller 220 controls the electrical core 210 to output current to the nebulizer 100 according to a detection signal of the sensor 250.
Further in the preferred embodiment shown in fig. 1, the power module 200 is provided with a charging interface 240 at the other end opposite to the receiving cavity 270 for charging the battery cells 210 after connection with an external charging device.
Further in the embodiment shown in fig. 1, the atomizer 100 may essentially comprise: a liquid-containing space 91 for storing a liquid medium; the atomizing core assembly 10A is used for sucking the liquid substrate from the liquid accommodating space 91 by capillary infiltration and heating the liquid substrate to be vaporized to generate aerosol for sucking.
Referring further to fig. 2-4, the structure of a preferred embodiment of the atomizer 100 of fig. 1 is shown. As shown, the nebulizer 100 has a proximal end 110 and a distal end 120 that are longitudinally opposite each other; in use, the proximal end 110 serves as the end to be used by a user for suction and the distal end 120 serves as the end to be received into the receiving cavity 270. Specific external configurations the atomizer 100 comprises a main housing 90, the main housing 90 being generally configured as a hollow cylinder and having an air inlet 94 at a proximal end 110; which has an opening at the distal end 120 to facilitate assembly of the various functional components within the main housing 90 through the opening.
In some embodiments, as shown in fig. 4-7, atomizer 100 may comprise the main housing 90 and atomizing core assembly 10A. Atomizing cartridge assembly 10A may be matingly coupled to main housing 90 via snap 573 and catch 93. The snaps 573 can be disposed on two opposing outer sides of the atomizing core assembly 10A and the detents 93 can be disposed on two opposing inner sides of the main housing 90, such that each snap 573 can be snapped into each respective detent 93 during assembly to provide a mounting connection of the atomizing core assembly 10A to the main housing 90. Alternatively, the atomizing core assembly 10A and the main housing 90 may be connected by an adhesive, or may be detachably connected.
Therein, the main housing 90 defines a liquid receiving space 91 and has a flue gas output passage 92 located within the main housing 90. For example, the liquid receiving space 91 may be defined by the inner surface of the main housing 90, the outer surface of the smoke output passage 92, and the upper surface of the atomizing core assembly 10A. Since the main housing 90 defines the liquid housing space 91, the main housing 90 may also be referred to as an atomization bin, an oil bin, or the like. The flue gas output channel 92 may be a flue gas output pipe.
The smoke output passage 92 may be formed at the center of the main housing 90 and extend in the longitudinal direction, which may be integrally prepared with the main housing 90 by a mold; the second end 923 of the smoke output passage 92, which is the upper end, forms an air suction port 94, and further outputs aerosol generated inside the nebulizer 100 to the air suction port 94. The end of the first end 921 of the flue gas output channel 92, which is the lower end, may have a slot 922, the slot 922 opens on the pipe wall of the flue gas output channel 92, and may have a square projection profile; the slots 922 may be two in number and may be oppositely disposed. A second end 923 of the flue gas outlet passage 92 opposite the first end 921 forms an air suction opening 94. The flue gas output channel 92 may be provided with a stop 924 adjacent the first end 921; the stopping portion 924 can be an annular step surface, which can be a transition surface between the section of the flue gas outlet channel 92 with the larger diameter and the first end 921 with the smaller diameter; the larger diameter section may extend to the second end 923. The stop 924 is adapted to stop cooperate with the upper surface of the second seal 70 (see fig. 8) to define the depth of insertion of the flue gas output channel 92 into the second seal 70.
As further shown in fig. 7 and 8, the atomizing core assembly 10A may include a liquid guiding member 10, a heating member 20, a first sealing member 30, a support seat 40A, and the like. The support base 40A may be a rigid structure for receiving and supporting the liquid guiding member 10, the heating member 20 and the first sealing member 30, so that the atomizing core formed by the liquid guiding member 10 and the heating member 20 is stably held in the main housing 90. Since the support base 40A is mainly used to support the atomizing core, the support base 40A may also be referred to as an atomizing core support assembly.
As shown in fig. 9, the liquid guiding member 10 may include an atomizing surface 11 and a liquid absorbing surface 12 opposite to the atomizing surface 11. The liquid guiding member 10 can be made of a material having capillary channels or pores, such as fiber cotton, a porous ceramic body, a glass fiber rope, a porous glass ceramic, a porous glass, and other hard or rigid capillary structures. 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 smoke output passage 92, which is preferably a plane extending along the cross section of the main housing 90.
The heating element 20 is arranged on the atomization surface 11 and is used for heating at least part of the liquid substrate absorbed by the liquid guide element 10 to generate aerosol when being electrified, and the aerosol is released into the smoke output channel 92 after escaping from the atomization 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. 8, 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.
As shown in fig. 10, the first sealing member 30 may be located between the liquid guiding member 10 and the bracket sidewall 44 of the supporting seat 40A, and is used for sealing the atomizing surface 11 from the liquid absorbing surface 12, that is, the liquid provided by the liquid accommodating space 91 can only enter the liquid guiding member 10 through the liquid absorbing surface 12 and then be delivered to the atomizing surface 11. The first seal 30 may be generally cup-shaped such that the fluid conducting member 10 may be received within a recess of the cup-shaped first seal 30. The first seal 30 may have a first open end 31, a first closed end 32 opposite the first open end 31, and a seal sidewall 33 extending from the first closed end 32 toward the first open end 31; the number of seal side walls 33 may be plural, for example for a generally cube shaped first seal 30, it may comprise four seal side walls 33. The first sealing element 30 is enclosed by a sealing element side wall 33 and a first closed end 32 to form a containing space for containing the liquid guide element 10 and exposing the atomization surface 11; for example, the atomization surface 11 may be substantially flush with the first open end 31, thereby being exposed outwardly of the first seal 30. The first sealing member 30 is further opened with a liquid inlet 34 on the side wall 33 thereof, so that the liquid suction surface 12 communicates with the outside through the liquid inlet 34, and further communicates with the liquid accommodating space 91 during assembly. In some embodiments, the liquid-diverting element 10 may be generally flat-plate shaped and supported by a support structure disposed within the first seal 30 such that the suction surface 12 of the liquid-diverting element 10 communicates with the exterior through the liquid inlet 34. The first sealing element 30 may be made of a sealing silicone material.
Referring to fig. 9 and 10, when the liquid guiding member 10 is placed in the first sealing member 30, the other five surfaces of the liquid guiding member 10 except the defogging surface 11 are all covered by the first sealing member 30, so that the liquid absorbed by the liquid guiding member 10 can be prevented from leaking from the surfaces, and the liquid leakage prevention effect is good. It should be noted that although the liquid inlet 34 is opened on the side wall 33 of the first sealing member 30, the side wall 33 of the first sealing member can still seal the liquid inlet 34, so as to prevent liquid leakage.
Further, the number of the liquid inlet ports 34 may be two; for example, two opposite side walls 33 of the first sealing member 30 are each provided with a liquid inlet 34. This may facilitate a constant supply of liquid to the drainage member 10.
In addition, the side wall 33 of the first sealing element 30, which is not provided with the liquid inlet 34, completely covers the corresponding side surface of the liquid guiding element 10. This allows for tightness against gases and liquids, for example, leakage of liquid out of these corresponding sides, absorption of external moisture, etc., can be avoided. The first sealing member 30 may be in the shape of a rectangular parallelepiped, and the two liquid inlets 34 may be opened in two opposite sealing member sidewalls 33 in the length direction of the first sealing member 30; accordingly, the two opposing seal sidewalls 33 across the width of the first seal 30 remain intact and void-free.
In some embodiments, as shown in connection with FIG. 10, the seal sidewall 33 of the first seal 30 may be provided with a closed, annular bead 37 that circumferentially surrounds the first seal 30. This enables the rib 37 to be held in close abutment with the inner wall of the support seat 40A when the first sealing member 30 accommodating the liquid guiding member 10 is assembled with the support seat 40A, thereby stably sealing the gap between the first sealing member 30 and the support seat 40A and preventing liquid leakage.
In some embodiments, as shown in connection with fig. 10, the first open end 31 of the first seal 30 may lie in a plane, e.g., may be aligned with the atomization surface 11; accordingly, the bead 37 may be disposed proximate the first open end 31. Alternatively, the first open end 31 of the first sealing member 30 may have a recessed end surface, for example, the top ends of two opposite sealing member side walls 33 in the width direction of the first sealing member 30 are each provided with a recessed notch, which may facilitate exposing a portion of two side surfaces of the liquid guiding element 10 accommodated in the first sealing member 30, thereby facilitating taking out the liquid guiding element 10 from the first sealing member 30; likewise, the ribs 37 may be disposed proximate such first open end 31 having a concave end surface such that the ribs 37 no longer lie in the same plane.
Referring to fig. 5, the supporting base 40A can accommodate the liquid guiding element 10, the heating element 20 and the first sealing member 30; and, the supporting seat 40A is connected with the main housing 90 in a matching way, so that the atomizing surface 11 of the liquid guiding element 10 faces the smoke output channel 92.
When the atomizing surface 11 of the liquid guiding element 10 is disposed to face the smoke output channel 92, since the atomizing surface 11 faces away from the power module 200 and 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 heat and atomizes the generated smoke, which does not need to pass through the liquid guiding element 10 itself, but directly enters the air suction channel of the smoke output channel 92 until reaching the air suction port 94 to be sucked by the user, thereby reducing the loss of the smoke when passing through the atomizing core itself, 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 300 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 300 in unit time can be further ensured.
In some embodiments, as shown in fig. 9, the liquid guiding element 10 may include a first wall portion 13 where the atomization surface 11 is located and two second wall portions 14 respectively extending from two sides of the first wall portion 13 away from the atomization surface 11, and a surface of the first wall portion 13 located between the two second wall portions 14 forms at least a part of the liquid absorption surface 12. The two second wall portions 14 may simply be support structures; the structure can also be made of the same material as the liquid guiding element 10, so that the liquid guiding element 10 can be supported in the first sealing element 30 and can play a liquid guiding role; that is, the opposing inner surfaces of the two second wall portions 14 may also be a part of the liquid suction surface 12. It will be readily appreciated that the two second wall portions 14 define between them a transversely extending liquid passage 17; when assembled, the liquid channel 17 extends from one of the inlet ports 34 of the first seal 30 towards the other inlet port 34 and is through the inlet port 34; in use, liquid substrate flowing from the liquid inlet channel 41 formed in the side wall of the support base 40A enters the liquid channel 17 and is absorbed by the capillary channel in the liquid guiding element 10.
Further, as shown in connection with fig. 9, the two second wall portions 14 may be connected by a connecting wall 15 at the end remote from the first wall portion 13. By using the connecting wall 15, the structural strength of the entire liquid guiding member 10 can be enhanced; furthermore, when the connection wall 15 and the two second wall portions 14 are made of the same porous material as the first wall portion 13, the connection wall 15 can also function as a liquid guide, which can absorb liquid and transmit it to the first wall portion 13 via the second wall portions 14. In addition, as shown in fig. 9, the connecting wall 15 may connect only a part of the distal ends of the two second wall portions 14, and for example, the length of the connecting wall 15 may be about one third of the length of the first wall portion 13. Alternatively, the connecting wall 15 may connect all of the distal ends of the two second wall portions 14, for example, the connecting wall 15 may extend in the longitudinal direction and connect all of the distal ends of the two second wall portions 14 in the direction in which the connecting wall 15 extends. It will be readily apparent that the wall surface of such a through-hole can be made to serve as the liquid-absorbing surface 12 by providing a through-hole extending along the length direction of the atomizing surface 11 of the liquid-guiding member 10 below the latter. Such a through hole may be a hole penetrating along the longitudinal direction of the liquid guiding member 10, or may be a blind hole starting from both ends of the liquid guiding member 10 and ending at the middle position of the liquid guiding member 10.
Further, as shown in conjunction with fig. 9, the connecting wall 15 may be disposed in parallel with the first wall portion 13. In addition, both sides of each second wall portion 14 may transition to the end of the second wall portion 14 through the arc 16; that is, both sides of each second wall portion 14 may be provided with chamfered shapes, which facilitates assembly of the liquid guiding member 10 into the first seal 30.
In some embodiments, as shown in connection with FIG. 10, the first seal 30 may be provided with a guide channel 35 extending from the loading port 34 into the first seal 30. By providing the guide groove 35, it is possible to facilitate guiding the liquid in the liquid accommodating space 91 into the first sealing member 30 by, for example, capillary action, and to prevent the liquid from stagnating at the liquid inlet 34; more specifically, due to the ventilation capability of the liquid guiding element 10, the external air may enter the liquid channel 17 under the action of the air pressure difference and flow to the liquid accommodating space 91 through the liquid inlet 34, which meets the liquid inputted through the liquid accommodating space 91 at the liquid inlet 34, and thus the liquid is stagnated at the liquid inlet 34; and the guide groove 35 can prevent such stagnation. Further, the guide groove 35 may be defined by two bars 36 projecting upward from the first closed end 32 of the first seal member 30. The two bars 36 can extend to abut against the connecting wall 15 of the liquid-conducting element 10 assembled inside the first seal 30. In addition, the number of the bars 36 may be three or more, so that each adjacent two of the bars 36 define one guide groove.
In some embodiments, as shown in fig. 5 and 8, the side wall of the support base 40A may be provided with a liquid inlet channel 41, and the liquid inlet channel 41 is respectively communicated with the liquid accommodating space 91 and the liquid suction surface 12 of the liquid guide member 10. The liquid inlet channel 41 may include a first portion extending in the longitudinal direction and communicating with the liquid housing space 91, and a second portion communicating with the liquid guide member 10; wherein the second portion may be horizontal or may be inclined downwardly from the first portion towards the drainage member 10, such inclined second portion further facilitating the direction of the liquid substrate towards the drainage member 10. In addition, the number of the liquid inlet passages 41 may be two, which may be respectively disposed at both sides of the support seat 40A. It is noted that the cross-section of the support base 40A may be square, circular, oval, etc.; moreover, even if the support seat 40A has a circular or elliptical cross section, it can be divided into, for example, four sides; for example, with the oval support seat 40A shown in fig. 8, two sides in the length direction thereof may be regarded as two opposite sides, two sides in the width direction thereof may be regarded as the other two opposite sides, and the two liquid inlet passages 41 are provided in the two opposite sides in the length direction, respectively.
In the above embodiment, by providing the liquid inlet channel 41, for example, the liquid of the tobacco juice can enter the liquid guiding element 10 through the liquid inlet channel 41, and is guided upwards to the atomizing surface 11 of the liquid guiding element 10 for atomization through the capillary phenomenon, the atomization amount of the tobacco tar is completely supplied through the 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. 8 and 15, the supporting base 40A may be provided with a conductive element 60; the number of conductive elements 60 may be two. Each conductive element 60 may include a first portion 61 extending at least partially within the support base 40A and a second portion 62 bent with respect to the first portion 61 toward the heating element 20 on the fluid-conducting element 10 within the support base 40A; the second portion 62 is intended to be brought into electrically conductive connection with the electrically conductive terminal 21 of the heating element 20, for example by abutting contact. At least a second portion 62 of the conductive element 60 extends or is exposed outside the support seat 40A and forms an electrical contact 63 for supplying power to the heating element 20. The first portion 61 of the conductive element 60 may also include a second electrical contact 64. The vertical portion of the first portion 61 and the second portion 62 may have the same width, and the horizontal portion of the first portion 61 (i.e., the portion where the second electrical contact 64 is provided) may have a slightly wider width.
At least a portion of the first portion 61 of the conductive element 60 may be molded into the support base 40A such that the second electrical contact 64 is exposed from the bottom of the support base 40A to facilitate an electrically conductive connection with the power module 200. For example, the conductive element 60 is at least partially embedded or embedded in the support base 40A; the conductive element 60 and the supporting base 40A can be integrally prepared by in-mold injection molding or hot press molding; in addition, the conductive element 60 may be formed by bending a sheet-shaped metal base material.
In some embodiments, the conductive element 60 may be made of a metal or alloy material having a low resistivity and high conductivity, such as gold, silver, copper, etc., which is used to conduct current between the power module 200 and the heating element 20 to power the heating element 20 during use. At least a portion of the lower end of the conductive element 60 is deformed, for example by stamping, to form a second electrical contact 64, and at least a portion of the upper end may be bent to form a resilient first electrical contact 63 in conductive connection with the heating element 20, thereby ensuring stable conductive contact with the heating element 20. The surface of the second electrical contact 64 may be flush with the surface forming the distal end 120 of the atomizer 100. The resilient first electrical contact 63 may comprise a bent V-shape or U-shape in the figures.
In some embodiments, as shown in conjunction with fig. 5 and 8, the support base 40A may define a first receiving space 45 and a second receiving space 51 separated by a partition 431; an air intake path is formed between the first housing space 45 and the second housing space 51, and the air intake path is configured to guide and convey the air flow in the second housing space 51 to the vicinity of the atomizing surface 11 in the first housing space 45. When assembled, the first receiving space 45 receives the liquid guiding element 10, so that the atomizing surface 11 faces away from the second receiving space 51 and faces the smoke output channel 92. The supporting seat 40A may have an open end, and the side wall of the supporting seat 40A between the atomizing surface 11 and the open end and the atomizing surface 11 define an atomizing chamber. Additionally, the air inlet path may be at least partially defined by an air inlet channel 47 on the support base 40A, and the air inlet channel 47 may terminate at the air inlet 471. The air flow can sequentially flow through the second receiving space 51 and the air inlet groove 47, and is delivered to the atomization surface 11 of the liquid guiding element 10 in the supporting seat 40A through the air inlet 471. The support base 40A may be formed as an integral structure or may be formed by assembling separate structures.
In some embodiments, as shown in fig. 5, 8 and 13, the support seat 40A may further be provided with an air inlet pipe 52, and the air inlet pipe 52 is communicated with the second receiving space 51 through a plurality of through holes 53. For example, the air inlet duct 52 may extend upward from the bottom of the support seat 40A toward the second receiving space 51; a plurality of through holes 53 may be opened in the end wall 54 of the intake duct 52; the end wall 54 is higher than the bottommost portion of the second housing space 51 in the depth direction of the second housing space 51 and lower than the partition 431. In this way, the portion of the second housing space 51 in the direction of the outside of the air inlet duct 52 is made to form a virtually leak-free container; thus, even if liquid leaks from the liquid accommodating space 91 or the liquid guide member 10 into the second accommodating space 51, it is accommodated by the second accommodating space 51 without leaking to the outside of the atomizer 100.
In addition, as shown in fig. 8 and 13, a plurality of leakage storage grooves 55 may be further formed on at least one of the bottom surface and the side surface of the second receiving space 51. The leakage reservoirs 55 may be recessed from the bottom surface and/or the side surface of the second receiving space 51, or may be defined by a plurality of ribs provided on the bottom surface and/or the side surface of the second receiving space 51. By forming these leakage liquid storage grooves 55, the liquid leaked into the second housing space 51 can be absorbed and stored by these leakage liquid storage grooves 55, for example, by capillary action, and the flow of the leaked liquid can be restricted.
In some embodiments, as shown in connection with fig. 8, the support base 40A may include a first bracket 40 and a second bracket 50 that are cooperatively coupled to each other. Wherein the partition 431, the air inlet 471 and the first receiving space 45 are formed on the first bracket 40; the second receiving space 51 is formed on the second bracket 50.
In some embodiments, as shown in fig. 8, 11 and 12 in combination, the first holder 40 may have a second open end 42, a second closed end 43 opposite the second open end 42, and a holder sidewall 44, the holder sidewall 44 and the second closed end 43 defining at least a first receiving space 45. When assembled, the liquid guiding element 10 is configured to be able to be placed into the first accommodating space 45 from top to bottom from the second opening end 42 so as to be accommodated by the first accommodating space 45, and the atomization surface 11 faces the second opening end 42; and the atomizing surface 11 and the holder sidewall 44 between the atomizing surface 11 and the second open end 42 of the first accommodating space 45 define an atomizing chamber; the atomizing chamber is the cavity that heating element 20 on atomizing surface 11 is located, and heating element 20 directly produces the aerosol that liquid heating atomizing becomes in the atomizing chamber during operation, and then exports through flue gas output passage.
Referring to fig. 8 and 11, when the liquid guiding member 10 is placed in the first frame 40, the second closed end 43 of the first frame 40 prevents the liquid absorbed by the liquid guiding member 10 from leaking downward, so that the leakage prevention effect is good.
In some embodiments, as shown in fig. 11 and 12, the bracket side wall 44 is provided with a liquid inlet channel 41, and the liquid inlet channel 41 is used for communicating with the liquid inlet 34 formed in the first sealing member 30, and further communicating with the liquid suction surface 12 of the liquid guiding element 10; for example, two opposing frame sidewalls 44 of the first frame 40 may each define an inlet channel 41. Further, the passage surface of each inlet passage 41 may be provided with a guide groove 46 terminating at the inner surface of the side wall 44 of the holder, the guide groove 46 being recessed with respect to the passage surface adjacent thereto. The guide groove 46 is used for aligning and communicating with the guide groove 35 of the first sealing member 30 installed in the first bracket 40, so that the liquid in the liquid accommodating space 91 can be guided into the first sealing member 30 by, for example, capillary action, and can be absorbed by the liquid guiding member 10. The guide groove 46 may open at the passage surface in any direction of the inlet passage 41, preferably at the passage surface of the bottom, so that the liquid flows under gravity first into the first seal 30 via the bottom. In addition, as shown in fig. 5, the liquid inlet channel 41 of the bracket side wall 44 may start from the second open end 42 and may extend toward the second closed end 43 to be lower than the atomization surface 11 of the liquid guide member 10.
Accordingly, the aforementioned air intake grooves 47 may be provided on the first bracket 40, for example, on the outer surface of the bracket side wall 44. The inlet slot 47 may begin at the second closed end 43 and terminate at the inlet port 471. On the rack side wall 44, the air inlet 471 is formed to penetrate through the outer surface of the rack side wall 44 to the atomizing chamber. Wherein the air inlet 471 is closer to the second open end 42 relative to the atomizing surface 11; that is, when the second opening end 42 is taken as a reference, the air inlet 471 is closer to the second opening end 42 than the atomization surface 11, so that the air inlet 471 is higher than the atomization surface 11 of the liquid guide element 10 accommodated in the first accommodation space 45. Alternatively, the air inlet 471 may be located between the atomizing surface 11 and the second opening end 42, and closer to the atomizing surface 11, such that the air inlet 471 is located above the atomizing surface 11 of the liquid guiding member 10 received in the first receiving space 45 (including: the air inlet 471 is higher than the atomizing surface 11; and the lowest portion of the air inlet 471 is flush with the atomizing surface 11). The air inlet channel 47 serves to convey the air flow via the air inlet 471 to the space above the atomizing surface 11, i.e. to the atomizing chamber. In this embodiment, by setting the air inlet 471 higher than the atomizing surface 11 of the liquid guiding member 10 received in the first receiving space 45, the liquid can be prevented from leaking from the atomizing surface 11 into the air inlet groove 47 through the air inlet 471.
In some embodiments, the air inlet 471 may be provided with an air flow guiding structure for guiding the air flow from the air inlet path towards the nebulizing surface 11. For example, as shown in connection with fig. 12, the air flow guiding structure may include a slope 472 formed on the first bracket 40 of the support base 40A and inclined with respect to the atomizing surface 11. The inclined surface 472 may be gradually inclined downward in a direction from the outer surface to the inner surface of the holder side wall 44 to be closer to the atomizing surface 11; thus, when the air flow is delivered from the air inlet groove 47 to the air inlet 471, the air flow can be guided toward the atomizing surface 11 by the inclined surface 472.
In some embodiments, as shown in connection with fig. 7, 11 and 12, a buffer reservoir 48 may be provided on the outer surface of the holder sidewall 44, the buffer reservoir 48 being in communication with the aerosolization chamber. For example, the buffer reservoir 48 may communicate with the space above the nebulization surface 11, i.e. with the nebulization chamber, via an overflow 481 which is provided in the side wall 44 of the holder.
In some embodiments, on a first side of the first rack 40, there is one first air intake tank 47 and two first cache reservoirs 48; the first air inlet tank 47 is located between the two first cache liquid storage tanks 48, and the air inlet 471 of the first air inlet tank 47 is located between the overflow ports 481 of the two first cache liquid storage tanks 48. The first side of the first bracket 40 may be a half side of the first bracket 40, which is located on one side of the central axial plane passing through the two opposite inlet channels 41.
Further, on the second side of the first bracket 40, a second air inlet tank 47 and two second buffer liquid storage tanks 48 may be further provided; the second air inlet tank 47 is located between the two second cache liquid storage tanks 48, and the air inlet 471 of the second air inlet tank 47 is located between the overflow ports 481 of the two second cache liquid storage tanks 48. Additionally, one of the two first cache reservoirs 48 may be in communication with one of the two second cache reservoirs 48; the other of the two first cache reservoirs 48 may be in communication with the other of the two second cache reservoirs 48. The second side of the first bracket 40 may be the other half side of the first bracket 40, which is located on the other side of the medial axis plane passing through the two opposite inlet channels 41.
Further, as shown in fig. 5 and 11 in combination, the portion of the first leg 40 below the inlet 471 or the atomizing surface 11 actually forms a container that is impervious to liquid. Therefore, the liquid in the liquid tank can be prevented from leaking downwards, and the liquid leakage prevention effect is good.
In some embodiments, as shown in fig. 7, 11 and 12, the air inlet tank 47 and the buffer reservoir tank 48 may be separated by a partition 442, so that the liquid in the buffer reservoir tank 48 may be prevented from entering the air inlet tank 47. The cache reservoir 48 may be a capillary reservoir. By providing the buffer reservoir 48, the excessive liquid on the atomizing surface 11 can flow into the buffer reservoir 48 through the overflow port 481, so that the excessive liquid can be absorbed and stored by, for example, capillary action, thereby preventing the liquid from leaking to other parts of the atomizer 100; that is, the buffer reservoir 48 is capable of adsorbing and retaining the condensate of the aerosol generated by the nebulizer 100, preventing their outward seepage. In particular, when the air inlet tank 47 is located between the two buffer reservoirs 48, the air enters the atomizing surface 11 of the liquid guiding element 10 from the middle air inlet tank 47, and when excessive condensate is on the atomizing surface 11 of the liquid guiding element 10, the incoming air can be pushed to the overflow ports 481 on both sides and enters the buffer reservoirs 48 from the overflow ports 481 on both sides, so that the condensate can be effectively prevented from flowing into the second bracket 50 from the air inlet tank 47 and flowing out.
Further, the length of the cache reservoir 48 may be set to be greater than the circumference of the first bracket 40. For example, the cache reservoirs 48 may take a circuitous and connected slot configuration, thereby forming longer cache reservoirs 48 on the outer surface of the first rack 40; in particular, the cache reservoir 48 may include a plurality of horizontal slots, and two adjacent slots may communicate with each other via a vertical slot; additionally, the vertical slots may be arranged to be vertically misaligned so that liquid from the overflow 481 will try to flow from the nearer horizontal slot to the farther horizontal slot. Further, the overflow port 481 may be disposed higher than the atomization surface 11 of the liquid guide member 10 accommodated in the first accommodation space 45.
In addition, as shown in fig. 5, 11 and 12, the first bracket 40 can be connected to the main housing 90 in a fitting manner, so that the atomizing surface 11 of the liquid guiding element 10 received in the first bracket 40 faces the smoke output channel 92, and the atomizing surface 11 is in air flow communication with the first end 921 of the smoke output channel 92, which is a lower end. When assembled, the first bracket 40 may be positioned entirely within the main housing 90 and such that the outermost contoured surface of the first bracket 40 is in substantially flush contact with the inside surface of the main housing 90; thus, the inside surface of the main housing 90 may be used to close the lateral openings of the air intake slots 47 and the cache reservoirs 48 on the first side of the first frame 40 and may also close the lateral openings of the cache reservoirs 48 on the second side of the first frame 40. In addition, the lateral opening of the air inlet slot 47 on the second side of the first bracket 40 can be closed by the second bracket 50.
Furthermore, in embodiments comprising a first support 40 and a second support 50, the aforementioned conductive element 60 may be provided on said second support 50; for example, the conductive element 60 may be molded on the second bracket 50. In addition, as shown in fig. 12, the bracket side wall 44 of the first bracket 40 may be provided with a first mating surface 443. The first mating surface 443 can be used for stop mating with the second bracket 50.
In some embodiments, as shown in fig. 8 and 13, the second bracket 50 may include a main body 57 and a blocking wall 56, and the blocking wall 56 may be higher than the main body 57 and the second receiving space 51 defined by the main body 57. The blocking wall 56 is provided at one side of the second bracket 50. The blocking wall 56 is used for matching connection with the first bracket 40. In addition, the partition 431 of the first bracket 40 may cover the second receiving space 51. As shown in fig. 12 and 13, the top surface 571 of the main body portion 57 and the bottom surface 432 of the second closed end 43 of the first bracket 40 can slide relative to each other, so that the first engagement surface 443 is in stop engagement with the blocking wall 56. In this way, it is possible to achieve the assembly of the first bracket 40 to said second bracket 50 by means of a lateral movement.
In some embodiments, as shown in fig. 5, 8 and 13, the main body 57 of the second bracket 50 may have an annular groove 572, and the annular groove 572 may have a sealing ring 59. The sealing ring 59 may be made of a sealing silicone material. When assembled, the sealing ring 59 serves to form a seal between the body portion 57 and the main housing 90 to prevent the passage of liquid therethrough. In addition, a magnetic attraction part 58 can be arranged in the second bracket 50. The magnetic attraction component 58 may be made of a ferromagnetic material such as stainless steel, and when the atomizer 100 is received in the receiving cavity 270, the magnetic attraction component can magnetically attract the magnetic attraction component disposed on the power module 200, so that the atomizer 100 is stably received in the receiving cavity 270. The magnetic attraction part 58 can be inserted into the mounting hole 581 of the second bracket 50, and the lower end of the magnetic attraction part 58 is flush with the lower end of the second bracket 50.
In some embodiments, as shown in connection with fig. 12, the bracket sidewall 44 of the first bracket 40 may have a void 444, the void 444 forming the first mating surface 443. For example, in two opposite sides of the bracket side wall 44, the thickness of one side may be thinned relative to the other side to form the hollow 444, and the hollow 444 may be used to receive the blocking wall 56 of the second bracket 50.
In addition, the first mating surface 443 may further include a positioning groove 445, and the blocking wall 56 may further be provided with a positioning block 561; the positioning block 561 is configured to be inserted into the positioning groove 445 to limit the first bracket 40 from moving in a direction away from the second bracket 50. The positioning groove 445 may be a groove extending horizontally on the first mating surface 443; accordingly, the positioning block 561 is also horizontally disposed.
In some embodiments, as shown in connection with FIG. 13, the retaining wall 56 may be semi-circular in cross-section. That is, the cross section of the main body portion 57 may be in a ring shape such as a circle, an ellipse, etc., and the blocking wall 56 may be a portion extending upward from one side of the central axis surface of the main body portion 57; thus, the semi-annular dam 56 may form a semi-enclosed structure for mating with the rack sidewall 44 of the first rack 40.
One of the aforementioned air intake grooves 47 may be defined between the first bracket 40 and the second bracket 50, and may be formed at least between the blocking wall 56 of the second bracket 50 and the first bracket 40, for example. For another example, the air inlet slot 47 may be disposed on the outer surface of the bracket side wall 44 of the first bracket 40, and the position of the blocking wall 56 corresponding to the air inlet slot 47 may be a laterally open surface capable of covering the air inlet slot 47; thus, when the first bracket 40 and the second bracket 50 are coupled to each other, the lateral opening of the air inlet groove 47 is covered by the blocking wall 56, so that air can flow only through the bottom opening of the air inlet groove 47 to the air inlet 471 of the air inlet groove 47, and does not flow out in the middle portion of the air inlet groove 47.
In some embodiments, as shown in fig. 8, 13 and 15, the conductive element 60 extends through the blocking wall 56, such that the blocking wall 56 supports the conductive element 60. Since the conductive element 60 can be made of sheet metal, and its own length is long and its moving range is large due to insufficient strength, the first part 61 of the conductive element 60 can be fixed by the support of the blocking wall 56, so that the second part 62 can be prevented from excessive lateral movement during assembly, and at the same time, the first electrical contact 63 of the second part 62 can be ensured to have enough pressing force with the conductive terminal 21.
In another embodiment, the second bracket 50 may include a blocking wall (not shown) higher than the body portion 57 and a reinforcing wall (not shown) higher than the body portion 57, and the conductive element 60 may extend through the reinforcing wall such that the reinforcing wall supports the conductive element 60; the stop wall may be a member spaced from the reinforcement wall and may merely serve as a stop fit with the bracket side wall 44 of the first bracket 40. In other words, the blocking wall 56, such as shown in fig. 13, may be divided into at least two portions spaced apart from each other, one portion serving as the reinforcing wall and the other portion serving as the blocking wall in this other embodiment.
In some embodiments, as shown in fig. 11 and 12, the overflow 481 formed on the side of the first bracket 40 having the vacancy 444 may also serve as a through hole 481A. The through hole 481A is disposed higher than the first mating face 443 and is used for inserting the second portion 62 of the conductive member 60 therethrough. As shown in fig. 15, the second portion 62 of the conductive element 60 is bent toward the through hole 481A with respect to the first portion 61; the second portion 62 can extend into the first support 40 through the through hole 481A, and is electrically connected to the heating element 20 disposed on the liquid guiding element 10. As described above, the number of the through holes 481A and the conductive elements 60 may be two. It is noted that the overflow 481 and the through hole 481A described herein may actually be one and the same through hole, which both allows the second portion 62 of the conductive element 60 to be inserted therethrough and serves as an overflow for excess liquid on the atomization surface 11 to flow outwardly therefrom. In addition, in the assembled configuration, the second portion 62 of the conductive element 60 can pass through only the through hole 481A without contacting the through hole 481A, in particular without contacting the lower surface of the through hole 481A; this can prevent the liquid from leaking out along the second portion 62 through the through hole 481A.
In some embodiments, as shown in fig. 8 and 14, the atomizing core assembly 10A of the atomizer 100 may further include a second seal 70, the second seal 70 may include a base body portion 76 and a skirt portion 71 extending from a periphery of the base body portion 76 to one side, and the base body portion 76 may further be provided with a liquid guide hole 72 and a plug hole 73, and a mounting hole 77 located between the liquid guide hole 72 and the plug hole 73. The second sealing member 70 may be made of a sealing silicone material. The second sealing element 70 is configured to be sleeved on the first support 40 of the support seat 40A, the first support 40 of the support seat 40A is at least partially inserted into the main housing 90, such that the skirt portion 71 of the second sealing element 70 is clamped between the first support 40 of the support seat 40A and the main housing 90 to form a seal, and the first end 921 of the smoke output channel 92 is configured to be inserted into the insertion hole 73.
Further, a check valve 80A may be provided on the second seal 70, the check valve 80A being adapted to open under the action of a pressure differential. Therefore, in the assembled nebulizer 100, air can be introduced into the liquid accommodating space 91 through the check valve 80A, so that a large negative pressure caused by insufficient liquid in the liquid accommodating space 91 is avoided, and the liquid is smoothly discharged from the liquid accommodating space 91 to the liquid guiding member 10. The check valve 80A may be a duckbill valve or the like that allows only air to enter the liquid-receiving space 91 from the outside. In addition, since the atomization surface 11 of the liquid guiding member 10 can be disposed upward, even if the liquid in the liquid accommodating space 91 leaks through the check valve 80A, the leaked liquid flows onto the atomization surface 11, and is absorbed by the liquid guiding member 10 or is heated and atomized on the atomization surface 11.
Furthermore, a flow guiding part 75 protruding from the hole wall and used for being matched with the slot 922 at the tail end of the smoke output channel 92 can be arranged in the insertion hole 73. For example, the diversion part 75 can be disposed at one end of the insertion hole 73 far away from the smoke output channel 92; the drainage part 75 may include two protrusions 751, and a drainage groove 752 is formed between the two protrusions 751. When the smoke output channel 92 is inserted into the insertion hole 73, the drainage groove 752 extends into the smoke output channel 92 for a distance from the outside of the smoke output channel 92. Thus, when the user is using the atomizer 100, if condensate is present in the smoke output channel 92, the condensate can be guided by the drainage grooves 752 downwards towards the atomizing surface 11, and the condensate is prevented from dripping on the atomizing surface 11 after being condensed into large lumps, which adversely affects the atomizing quality.
In some embodiments, as shown in fig. 8 and 14, the base portion 76 may be provided with a valve plate 78 on the other side away from the skirt portion 71, and the valve plate 78 corresponds to the mounting hole 77. The mounting hole 77 can be internally provided with a ventilation bracket 80; wherein the ventilation bracket 80 may be a rigid structure and has a ventilation hole 81 (see fig. 5); the breather bracket 80 is installed in the installation hole 77 such that the valve sheet 78 covers one port 82 of the breather hole 81; the valve plate 78 is used to seal the port 82 or open the port 82 under the action of a pressure differential, thereby functioning as a one-way valve. It is noted that the second seal 70 and the breather support 80 may form a nebulizer seal assembly for sealing between the first support 40 and the main housing 90; meanwhile, the ventilation bracket 80 can reinforce the second sealing element 70, so as to prevent the second sealing element 70 from deforming due to insufficient strength when the first end 921 of the smoke output channel 92 is inserted into the insertion hole 73.
In some embodiments, as shown in fig. 8, the first end 781 of the valve plate 78 is connected to the base body 76, and other portions of the valve plate 78 are separated from the base body 76. In this way, the valve plate 78 is made more flexible to move in response to the pressure differential.
Further, the base portion 76 may be provided with a connection block 761 and a recess 762, the first end 781 of the valve plate 78 is connected to the connection block 761, and the recess 762 is located on a side of the connection block 761 away from the first end 781 of the valve plate 78. By providing the concave portion 762, the strength of the connecting block 761 connected to the first end 781 can be weakened, so that the valve plate 78 can move more easily under the pressure difference without being excessively restricted by the base portion 76.
Further, as shown in fig. 5 and 8, the vent hole 81 may be eccentrically disposed on the ventilation bracket 80, such that the vent hole 81 is closer to the second end 782 opposite to the first end 781 of the valve plate 78. This arrangement allows the free end of the valve sheet 78, which is easy to move, to engage with the vent hole 81.
In addition, the part of the ventilation bracket 80 contacting the valve plate 78 may be a boss 83, and the vent hole 81 penetrates through the boss 83. As further shown in FIG. 5, the vent 81 may have a first section and a second section connected, the first section being adjacent to the valve plate 78 and having a cross-sectional dimension smaller than a cross-sectional dimension of the second section.
In addition, as shown in fig. 8, the ventilation bracket 80 may include a base portion 84 and an annular flange 85 protruding from a side portion of the base portion 84. The base portion 84 may be a column extending uniformly from bottom to top, and the cross section may be square, circular, oval, and the like, and particularly may be a rectangle with four arc-shaped chamfers. Accordingly, as shown in connection with fig. 13, the mounting hole 77 may include a first portion 771 that receives the base portion 84 and a second portion 772 that receives the annular flange 85. The breather support 80 is prevented from falling off the second seal 70 by the annular flange 85 engaging a stop in the second portion 772. At the same time, the mating surfaces of the annular flange 85 and the second portion 772 also form a tortuous path in the up-down direction, which can better prevent liquid from leaking therethrough.
In addition, the number of the mounting holes 77 may be two, the insertion hole 73 may be provided at a central position of the base body portion 76, and one mounting hole 77 is provided between each of the liquid guide holes 72 and the insertion hole 73.
Further, as shown in fig. 14, two of the mounting holes 77 may be symmetrically disposed about the insertion hole 73. In addition, as shown in fig. 8, the two connection blocks 761, the two concave portions 762 and the two valve plates 78 may be disposed in a rotational symmetry manner with respect to the insertion hole 73.
In some embodiments, as shown in fig. 14, the thickness of the base body portion 76 where the liquid guide hole 72 is located may be smaller than the thickness of the base body portion 76 where the mounting hole 77 is located. In addition, the upper surface of the base portion 76 may lie in a single plane.
In addition, a stopping portion 79 may be further disposed at an end of the insertion hole 73 away from the valve plate 78, and the stopping portion 79 protrudes inward from the insertion hole 73 so as to abut against the smoke output channel 92 in the main housing 90. The inner surfaces of said stops 79 may be aligned with the inner surfaces of the flue gas output channel 92, i.e. they may be located in the same cylindrical surface, e.g. a cylindrical surface. In addition, two protrusions 751 of the drainage portion 75 may extend upward from the end of the stopping portion 79. The inner surfaces of the two cams 751 may likewise be aligned with the inner surface of the flue gas outlet channel 92, i.e. they may lie within the same cylindrical surface, e.g. a cylindrical surface.
In some embodiments, as shown in fig. 14, a protruding ridge 763 may be further disposed on the base 76 on the other side away from the valve plate 78, and the protruding ridge 763 is located between the insertion hole 73 and the mounting hole 77. For example, the ridge 763 may be an arc-shaped structure disposed adjacent to the insertion hole 73; the number of the protruding ridges 763 may be two, and they may be oppositely disposed with respect to the insertion hole 73. When the second seal 70 is fitted over the first bracket 40, both ends of each of the projecting ridge portions 763 abut against the inner surface of the first bracket 40. In this way, a step is formed between the ridge portion 763 and the lower surface of the base body portion 76, which prevents formation of a vortex when the atomizer 100 is sucked; in addition, since such a step forms a receiving space with the first bracket 40, it can be used to receive condensate accumulated in the atomizing chamber when the atomizer 100 is inverted, and thus such condensate can be prevented from flowing out of the smoke outlet passage 92 when the atomizer 100 is inverted.
In some embodiments, as shown in fig. 8 and 14 in combination, the sidewall of the first bracket 40 of the support seat 40A defining the first receiving space 45 may be provided with a stepped portion 441, and the stepped portion 441 is used for supporting a portion of the second seal 70 inserted into the first receiving space 45. Therefore, when the first end 921 of the smoke output channel 92 is inserted into the insertion hole 73, the second sealing member 70 can be supported by the step portion 441, so as to prevent the second sealing member 70 from being deformed due to losing the support.
Referring to fig. 16, a schematic cross-sectional view of an atomizer 100' according to another embodiment of the present invention is shown. In the embodiment shown in fig. 16, the atomizer 100' differs from the atomizer 100 shown in fig. 2 to 15 only in the second seal 70, and the other structures may be identical. For example, the atomizer 100' may include the same liquid directing element 10, heating element 20, first seal 30, first support frame 40, second support frame 50, electrically conductive member 60, and main housing 90. However, the second seal 70 'in the described atomizer 100' may differ from the second seal 70 in the atomizer 100 shown in fig. 2-15; specifically, as shown in fig. 17, the second seal 70' may be different in the manner of ventilation from the second seal 70; the second sealing member 70' may have a ventilation groove 74, wherein the ventilation groove 74 is used for communicating the atmosphere with the liquid accommodating space 91 in the main housing 90, and is used for introducing air into the liquid accommodating space 91 under the action of pressure difference. When the second sealing member 70 'is fitted over the first bracket 40, the opening of the ventilation groove 74 facing the first bracket 40 is covered by the inner surface of the first bracket 40, thereby forming a gas passage extending from the bottom side to the top side of the second sealing member 70'. The breather groove 74 may be a capillary groove, which may be a groove extending uniformly up and down on one side of the second seal 70'; furthermore, a plurality of, for example, square or triangular recesses 741 may be provided on two opposing groove surfaces of such a groove extending vertically in unison. Due to the capillary action, the liquid from the liquid containing space 91 can be held in the air vent groove 74, and only when the negative pressure of the liquid containing space 91 reaches a certain level, the outside air can enter the liquid containing space 91 by the pressure difference.
Referring to fig. 18, a perspective view of a second bracket 50' according to another embodiment of the present invention is shown. In the embodiment shown in fig. 18, the second bracket 50' differs from the second bracket 50 shown in fig. 2 to 17 only in the blocking wall 56, and the other structures may be identical; also, the second bracket 50' is equally applicable to the atomizer 100 shown in fig. 2 to 17. Specifically, as shown in fig. 18, the blocking wall 56 may be opened with a recess 562 at a portion corresponding to the second air intake groove 47 of the second side of the first bracket 40 shown in fig. 12, for example. For example, the groove 562 may penetrate through the thickness direction of the blocking wall 56 and may be opened to the top surface 571 of the main body portion 57 of the second bracket 50'. Thus, when the second bracket 50' is applied to the atomizer 100 shown in fig. 2 to 17, the first air inlet groove 47 opened on the first side of the first bracket 40 forms a first air inlet channel, and the first air inlet channel is communicated with the atomizing surface 11 of the liquid guide element 10 accommodated in the first bracket 40; the recess 562 forms together with the second inlet channel 47 a second inlet channel, which also communicates with the atomizing surface 11. Wherein the first intake passage and the second intake passage may have the same passage size; for example, the first and second intake passages may have substantially the same shape, so that the amount of intake air on both sides of the first bracket 40 may be kept uniform to obtain a better atomization effect; alternatively, the first intake passage and the second intake passage may simply ensure the same area of the respective minimum passage cross-sections, which also enables the amount of intake air to be kept uniform on both sides of the first bracket 40.
Referring to FIGS. 19 and 20, there is shown a perspective view of an atomizing core assembly 10B provided in accordance with another embodiment of the present invention. In the embodiment shown in fig. 19 and 20, the atomizing core assembly 10B differs from the atomizing core assembly 10A shown in fig. 2 to 17 only in the first support 40, the second support 50 and the conductive member 60, and other structures may be identical. Specifically, as shown in fig. 19, a first air intake groove 47 is provided on a first side of the first bracket 40; the first air inlet groove 47 is used for forming a first air inlet channel, and the first air inlet channel is communicated with the atomizing surface 11 of the liquid guide element 10 accommodated in the first bracket 40. As shown in fig. 20, on the second side of the first bracket 40, a second air inlet groove 47 is provided; the blocking wall 56 of the second bracket 50 is provided with a groove 562 at a portion corresponding to the second air inlet groove 47, the groove 562 and the second air inlet groove 47 together form a second air inlet channel, and the second air inlet channel is also communicated with the atomizing surface 11. Also, the first and second intake passages may have the same passage size to keep the amount of intake air on both sides of the first bracket 40 uniform, thereby obtaining a better atomization effect. Wherein the blocking wall 56 of the second bracket 50 shown in fig. 20 has a shorter height than the second bracket 50' shown in fig. 18; accordingly, the portion of the second side of the first bracket 40 that defines the cache reservoir 48 may have a higher height to form a complementary configuration with the blocking wall 56. In addition, since the blocking wall 56 shown in fig. 20 has a shorter height, the first portion 61 of the conductive element 60 on the second bracket 50 can be arranged to have a wider width in the vertical direction than the second portion 62, so that the first portion 61 itself can also play a role of supporting, and the second portion 62 can be prevented from excessive lateral movement during assembly. It is noted that it is not necessary to provide all of the vertical portions of the first portion 61 of the conductive member 60 with a wide width, as long as it is ensured that a portion protruding from the blocking wall 56 and another portion adjacent to the portion and embedded in the blocking wall 56 have a wide width. The electronic atomizer 300 of the present invention and the various components of the atomizer 100 thereof have been described above. When the electronic atomizer 300 is needed for suction, the power switch of the power supply assembly 200 may be turned on first, so that the power supply assembly 200 supplies power to the atomizer 100; then, when the user inhales the suction nozzle where the air suction port 94 of the atomizer 100 is located, the atomizer 100 may be started to operate by the controller 220 of the electronic atomization device 300 according to the inhalation operation, 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 an aerosol, and the external air can sequentially flow through the air inlet pipe 52, the second containing space 51 and the air inlet groove 47, and is delivered to the upper side of the atomizing surface 11 of the liquid guiding element 10 in the first bracket 40 through the air inlet 471, so as to carry the formed aerosol out of the smoke output channel 92.
