Technical Field

The embodiment of the application relates to the technical field of electronic atomization, 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.

An example of such a product is a heating device that releases a compound by heating rather than burning the material. For example, the material may be tobacco or other non-tobacco products, which may or may not include nicotine. As another example, there are aerosol providing articles, e.g. so-called electronic atomising devices. These devices typically contain a vaporizable liquid that is heated to vaporize it, thereby generating an inhalable aerosol.

As further shown in fig. 3-5, the interior of the main housing 10 is provided with a reservoir 12 for storing a liquid substrate, and an atomizing assembly for drawing the liquid substrate from the reservoir 12 and heating the atomized liquid substrate. In the schematic cross-sectional structure shown in fig. 5, a flue gas conveying pipe 11 is axially arranged in the main housing 10, and a liquid storage cavity 12 for storing a liquid matrix is formed in a space between an outer wall of the flue gas conveying pipe 11 and an inner wall of the main housing 10; a first end of the smoke transport tube 11 opposite to the proximal end 110 is in communication with the mouthpiece a, so as to transport the generated aerosol to the mouthpiece a for inhalation.

Further as shown, the flue gas delivery tube 11 and the main housing 10 are integrally molded by using a moldable material, and the prepared liquid storage cavity 12 is open or opened towards the distal end 120.

The main housing 10 further includes:

In particular, second wicking element 30 is formed from a flexible strip or rod of fibrous material, such as cotton fibers, nonwoven fibers, sponges, or the like. In use, the second portion 32 is used for wicking the liquid matrix and then is transferred to the first portion 31 by capillary infiltration; the heating element 40 is configured to at least partially surround the first portion 31 and heat at least part of the liquid substrate of the first portion 31 to generate an aerosol. As shown in fig. 3 to 5, the heating element 40 has a spiral heating wire structure, and a resistive metal such as fe-cr-al alloy, nichrome alloy, etc. may be used as the material.

In an alternative embodiment, the first portion 31 of second drainage element 30 in FIG. 5 extends approximately 9mm in length and the second portion 32 extends approximately 7.5mm in length. The heating element 40 has an inner diameter in the range of about 2.3 to 2.6 mm.

In practice, the first liquid guiding member 50 is a layer of organic porous fibers in a sheet or block shape extending along the cross-sectional direction of the main housing 10. When assembled, first fluid directing element 50 is positioned adjacent an upper surface of reservoir 12 opposite reservoir 12 and is configured to draw in the liquid substrate and deliver the liquid substrate to contacting second portion 32 of second fluid directing element 30, opposite a lower surface of reservoir 12, as indicated by arrow R1 in FIG. 5. And the first liquid guiding element 50 is provided with a first inserting hole 51 for the flue gas conveying pipe 11 to pass through.

In a specific implementation, the first liquid guiding element 50 is made of 138# hard synthetic organic polymer cellucotton with the weight of 0.1-0.9 mg/mm ³ The density of (a); the overall first fluid conducting member 50 weighs about 0.04 to 0.06g. First drainage element 50 is formed from oriented fibers that are substantially aligned in a lengthwise orientation. For example, fig. 6 shows a microscopic topography of polypropylene fibers with orientation arrangement in an embodiment, and the orientation fibers are arranged in the length direction of the first liquid guiding member 50, so that the first liquid guiding member 50 has a strong bending resistance and is hard.

With further reference to fig. 7 and 8, the retaining structure within the bracket 70 for retaining the second drainage member 30 includes:

a first holding recess 71 disposed on the inner bottom wall extending in the width direction of the main housing 10 for holding the first portion 31 of the second liquid leading member 30; and a second retaining cavity 72 extending in the longitudinal direction of the main housing 10 for retaining the second portion 32 of the second liquid leading member 30.

In the preferred embodiment shown in fig. 7 and 8, the bracket 70 is preferably made of a flexible material such as silicone or a thermoplastic elastomer, and the outer wall of the first support portion 71 is provided with a first rib 76 extending in the circumferential direction; and/or the outer wall of the second retaining cavity 72 is provided with a second rib 75 extending in the axial direction. In implementation, the first rib 76 and the second rib 75 are used to seal the gap between the support frame 70 and the main housing 10.

In the design of the air flow path during suction, see the embodiment shown in fig. 3, the holder 70 is further provided with a second air inlet 77 towards the end cap 20 for the external air entering from the first air inlet 22 to enter the nebulization chamber inside the holder 70; then the aerosol in the atomizing chamber is carried and output by the smoke transmission pipe 11 which penetrates through the first plug hole 51.

As further shown in fig. 7 and 8, the inner wall of the holder 70 is provided with a plurality of ribs 73 extending in the longitudinal direction, and capillary channels 731 for adsorbing and retaining aerosol condensate in the nebulizing chamber are formed between the ribs 73. In practice, the ribs 73 have a width of about 0.5 to 1.5mm and the capillary groove 731 has a width of less than 2mm.

With further reference to fig. 7, 8, 9, 11 and 12, the inlet end of the flue gas outlet duct 11 facing away from the mouthpiece a is provided with a first notch 111; the first notches 111 are preferably two in number and are oppositely disposed in the thickness direction of the main housing 10. In cooperation with the first notch 111, the bracket 70 is provided with a rib 74 extending at least partially into the first notch 111. After assembly, both side surfaces of the rib 74 are not in contact with both side surfaces of the first notch 111, and a certain distance is maintained between the rib 74 and both side surfaces of the first notch 111 according to fig. 12. The spacing is further controlled to be less than 2mm, thereby forming capillary channels for capillary action therebetween. The condensate falling or flowing from the flue gas outlet pipe 11 to the air inlet end is absorbed and guided into the atomizing chamber of the bracket 70 by the capillary force of the capillary channel, as shown by an arrow R4 in fig. 12, so that the condensate is prevented from being accumulated in the flue gas outlet pipe 11 to form a liquid column, and the problem of sucking the condensate is relieved or eliminated.

Referring to FIGS. 7 and 8, to ensure that the rib 74 extends into the first gap 111 of the flue gas outlet duct 11, the rib 74 has a height greater than the height of the rib 73 and a width equal to the width of the rib 73. Further in the preferred embodiment shown in fig. 8, the projection height of the rib 74 varies, and in particular, the upper end portion is higher than the other portions in the longitudinal direction.

In the implementation shown in FIG. 9, the cross-sectional shape of the flue gas outlet duct 11 is elliptical; and the elliptical shape is such that the major axis B1 is the width direction of the main housing 10 and the minor axis B2 is the thickness direction of the main housing 10, and further the condensate in the flue gas outlet pipe 11 tends to gather more at the end with the larger curvature of the major axis B1. And then the tip of flue gas output tube 11 is provided with the second breach 112 that is close to main casing body 10 width direction's at least one side, makes the great tip of curvature of major axis B1 be the space of fretwork through this second breach 112, and then eliminates the gathering of condensate here and turns to gathering more to the position that is close to first breach 111, and then be convenient for guide to the atomizing chamber under the cooperation of bead 74 more.

In the preferred implementation shown in fig. 9, the first notch 111 has a width greater than the second notch 112; the width of the first notch 111 in the implementation is about 2.4mm and the width of the second notch 112 is about 1mm.

In the embodiment shown in FIGS. 11 and 12, the flue gas outlet duct 11 has an inclined duct wall 113 near the first notch 111; in use, aerosol condensate on the inner wall of the flue gas outlet conduit 11 is directed by the inclined conduit wall 113 towards the first gap 111, as indicated by arrow R4 in fig. 12, and then absorbed by the capillary channel formed by the rib 74 and the first gap 111 onto the surface of the rib 74 and flows downwardly into the aerosolization chamber in the stent 70. And as can be seen in both fig. 5 and 12, the rib 74 is not in contact with the surface of the first notch 111.

In use, as the liquid medium is consumed, the negative pressure in reservoir chamber 12 will gradually increase, which will affect the liquid medium to leave reservoir chamber 12 and transfer to second fluid conducting element 30; and then be provided with in the atomizer 100 and be used for supplementing the atmospheric pressure balanced passageway of air in the stock solution chamber 12, slow down the smooth transmission of the negative pressure assurance liquid matrix in the stock solution chamber 12. Referring specifically to fig. 7 to 10, the air pressure balance passage includes two passage portions that are sequentially communicated, i.e., a first passage portion indicated by an arrow R31 in fig. 7 and 8 and a second passage portion indicated by an arrow R32 in fig. 10; specifically, the method comprises the following steps:

the inner walls of the main housing 10 near both sides in the width direction are provided with at least one rib 14, and particularly, the number of ribs 14 is two in fig. 9 and 10, and a certain interval 141 is left between them. In cooperation with this spacing 141, the peripheral sidewall of rigid first drainage element 50 of FIG. 3 is configured to have a flat portion 52, flat portion 52 resting on bead 14 after assembly, thereby defining and maintaining spacing 141 unfilled or blocked;

further, the surface of the bracket 70 near the first liquid guide member 50 is provided with air grooves 79, and the air grooves 79 are located at both side ends of the bracket 70 near the width direction in fig. 7 and 8; one side of the air groove 79 is communicated with the space inside the bracket 70, i.e. the atomizing chamber, and the other side is communicated with the above space 141, so that the air in the atomizing chamber can pass through the air groove 79 along an arrow R31 in fig. 7 and 8, and then enters the liquid storage chamber 12 of the main housing 10 from the space 141 along an arrow R32 in fig. 10, and the negative pressure in the liquid storage chamber 12 is relieved or eliminated.

In the preferred embodiment shown in fig. 8 and 9, ribs 13 are also provided in main housing 10 for abutting and pressing first fluid conducting member 50 from the upper surface of first fluid conducting member 50 after assembly.

Also, on the wall of the first holding recess 71, there are provided capillary grooves 711 extending in the thickness direction of the main housing 10, the capillary grooves 711 being located on both sides of the portion of the heating element 40 or the first section 31 surrounded by the heating element 40 in the width direction of the main housing 10. A gap or space is ultimately formed between the first portion 31 and a location proximate the atomization zone heated by the heating element 40 for buffering the liquid substrate to prevent the liquid substrate from flowing or passing directly and relatively quickly to the surrounding portions of the heating element 40, slowing down frying oil.

Referring to fig. 7 and 8, the second holding cavity 72 has on its inner wall a capillary groove 722 extending from the upper end to a capillary groove 711 in the longitudinal direction; the capillary grooves 722 serve to adsorb and buffer the liquid matrix that seeps out of the second channel portion of the air pressure balance channel during air compensation, and also to regulate the efficiency of the liquid matrix flowing over the surface of the second portion 32. As can be seen in fig. 8, the upper end of the capillary groove 722 is in communication with the air groove 79; and when liquid matrix in reservoir 12 seeps into air groove 79 against the direction indicated by arrow R32, it can be drawn into capillary channel 722 and flow downward, as indicated by arrow R4 in fig. 13.

In this implementation, capillary groove 722 extends a length greater than second portion 32, at least from air groove 79 all the way into first retention cavity 71, and also at least partially adjacent to a surface of first portion 31. Further, in use, capillary channel 722 can directly supply liquid matrix to first portion 31.

As further shown in fig. 7 and 8, the air grooves 79 are defined by the protrusions 721 of the bracket 70 at the upper end thereof around the second holding cavity 72. According to the illustration, the air groove 79 is at least partially curved and surrounds the projection 721 of the second retaining cavity 72.

Fig. 14 shows a further perspective view of the heating element 40, including the first and second

electrical pins

41, 42 arranged opposite one another along the length, and the first and second spiral coils 410, 420 extending between the first and second

electrical pins

41, 42. In implementation, the first spiral coil 410 and the second spiral coil 420 are powered by the first electrical pin 41 and the second electrical pin 42 simultaneously and thus are in parallel. Structurally, the first spiral coil 410 and the second spiral coil 420 are closely aligned. In an alternative implementation, the first and second spiral coils 410 and 420 have about 3-10 turns or windings and an extended length of about 4-7 mm, and in fig. 13 they have 5 turns or windings and a design length of 6.5 mm.

As shown in fig. 14, the first spiral coil 410 and the second spiral coil 420 are not overlapped in the radial direction but are juxtaposed or staggered in the axial direction, at least they are each different in position relative to the first portion 31 along the extending direction of the first portion 31 after assembly, and thus have a larger contact area heat generation efficiency with the first portion 31.

The wire material used for the first and second

electrical pins

41 and 42 has a diameter larger than that of the wire material used for the first and second spiral coils 410 and 420; that is, the first and second

In the implementation shown in fig. 44, the resilient connecting portion 42e is cantilevered with respect to the body portion 62 e; or the resilient connection 42e may be defined by a suspension of the conductive element 60e relative to the body portion 62 e.

As further shown in fig. 41, the two conductive members 60e clamp the second liquid guide member 30e from both sides in the width direction, respectively, and then stable assembly is achieved.
