Description

Atomizer, electronic atomization device and sealing element for atomizer

Technical Field

The embodiment of the application relates to the technical field of electronic atomization, in particular to an atomizer, an electronic atomization device and a sealing element for the atomizer.

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 e-vapor devices. These devices typically contain a liquid that is heated to vaporize it, thereby generating an inhalable aerosol. The liquid may comprise nicotine and/or a fragrance and/or an aerosol generating substance (e.g. glycerol). In the above heating device, an annular seal ring having a circular cross section is generally provided between the fitting gaps of the housings, for sealing the fitting gaps of the housings; the above sealing ring has a low interference amount, and cannot have a sufficient sealing effect.

Further in the preferred embodiment shown in fig. 1, the power supply mechanism 200 is provided with a charging interface 240 at the other end facing away from the receiving cavity 270, for charging the battery cells 210.

The embodiment of fig. 2 to 5 shows a schematic structural diagram of one embodiment of the atomizer 100 of fig. 1, including:

a main housing 10; as shown in fig. 2 to 3, the main casing 10 is substantially in the shape of a flat cylinder; main housing 10 has a proximal end 110 and a distal end 120 opposite along its length; wherein, according to the requirement of common use, the proximal end 110 is configured as one end of the user for sucking the aerosol, and a nozzle opening A for the user to suck is arranged on the proximal end 110; the distal end 120 is used as an end for coupling with the power supply mechanism 200, and the distal end 120 of the main housing 10 is open, on which the detachable end cap 20 is mounted, and the open structure is used for mounting necessary functional components to the inside of the main housing 10.

Meanwhile, the end cap 20 is further provided with a first air inlet 23 for allowing external air to enter into the atomizer 100 during suction.

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. Wherein the atomization assembly generally includes a capillary wicking element for drawing the liquid substrate, and a heating element coupled to the wicking element, the heating element heating at least a portion of the liquid substrate of the wicking element during energization to generate the aerosol. In alternative implementations, the liquid-conducting element comprises a flexible fiber, such as a cotton fiber, a nonwoven, a fiberglass cord, or the like, or a porous material having a microporous structure, such as a porous ceramic; the heating element may be printed, deposited, sintered, or physically assembled onto or wrapped around the wicking element.

Further in the preferred implementation shown in fig. 3-5, the atomizing assembly comprises: a porous body 30 for sucking and transferring the liquid matrix, and a heating element 40 for heating and vaporizing the liquid matrix sucked by the porous body 30. Specifically, the method comprises the following steps:

in the schematic cross-sectional structure shown in fig. 5, a flue gas conveying pipe 11 is arranged in the main housing 10 along the axial direction; a reservoir 12 for storing a liquid medium is also provided in the main housing 10. In practice, the flue gas transport pipe 11 extends at least partially within the reservoir 12, and the reservoir 12 is formed by the space between the outer wall of the flue gas transport pipe 11 and the inner wall of the main housing 10. The first end of the smoke transport tube 11 opposite to the proximal end 110 is communicated with the mouth a of the suction nozzle, and the second end of the smoke transport tube opposite to the distal end 120 is in airflow connection with the atomizing chamber 340 defined between the atomizing surface 310 of the porous body 30 and the end cap 20, so that the aerosol generated by the heating element 40 and released to the atomizing chamber 340 is transported to the mouth a of the suction nozzle for smoking.

Referring to the structure of the porous body 30 shown in fig. 3, 4 and 5, the shape of the porous body 30 is configured to be, in embodiments, a generally, but not limited to, a block-like structure; according to a preferred design of this embodiment, it comprises an arched shape with an atomizing surface 310 facing the end cap 20 in the axial direction of the main housing 10; wherein, in use, one side of the porous body 30 facing away from the atomizing surface 310 is in fluid communication with the liquid storage cavity 12 to absorb the liquid substrate, and the microporous structure inside the porous body 30 conducts the liquid substrate to the atomizing surface 310 to be heated and atomized to form aerosol, and the aerosol is released or escapes from the atomizing surface 310.

Of course, the heating element 40 is formed on the atomizing surface 310; and, after assembly, the second electrical contact 21 abuts against the heating element 40 to supply power to the heating element 40.

With further reference to fig. 3 to 5, in order to assist the mounting and fixing of the porous body 30 and the sealing of the reservoir chamber 12, a flexible second sealing member 50, a holder 60 and a flexible first sealing member 70 are further provided within the main housing 10, both sealing the opening of the reservoir chamber 12 and fixedly holding the porous body 30 inside. Wherein:

in a specific structure and shape, the flexible second sealing element 50 is substantially in a hollow cylindrical shape, and the interior of the flexible second sealing element is hollow for accommodating the porous body 30 and is sleeved outside the porous body 30 in a close fit manner.

The rigid holder 60 holds the porous body 30, which is sleeved with the flexible second sealing element 50, and in some embodiments may include a substantially annular shape with an open lower end, and the holding space 64 is used for accommodating and holding the flexible second sealing element 50 and the porous body 30. The flexible second sealing member 50 can seal the gap between the porous body 30 and the support 60, and prevent the liquid medium from leaking out of the gap; on the other hand, the flexible second sealing member 50 is located between the porous body 30 and the holder 60, which is advantageous for the porous body 30 to be stably accommodated in the holder 60 without coming loose.

A first flexible sealing member 70 is provided between the reservoir 12 and the support frame 60 and has a profile adapted to the cross-section of the internal profile of the main housing 10 to seal the reservoir 12 against leakage of the liquid substrate from the reservoir 12. Further to prevent the contraction deformation of the flexible first sealing element 70 from affecting the tightness of the seal, the support is provided by the above bracket 60 being received in the flexible first sealing element 70.

After the installation, in order to ensure the smooth transfer of the liquid substrate and the output of the aerosol, the flexible first sealing element 70 is provided with a first liquid guide hole 71 for the liquid substrate to flow through, the bracket 60 is correspondingly provided with a second liquid guide hole 61, and the flexible second sealing element 50 is provided with a third liquid guide hole 51. In use, the liquid medium in the reservoir 12 flows through the first liquid guiding hole 71, the second liquid guiding hole 61 and the third liquid guiding hole 51 in sequence to the porous body 30 retained in the flexible second sealing element 50, as shown by an arrow R1 in fig. 4 and 5, and then is absorbed and transferred to the atomizing surface 310 for vaporization, and the generated aerosol is released into the atomizing chamber 340 defined between the atomizing surface 310 and the end cap 20.

In the aerosol output path during the suction process, referring to fig. 3 to 4, the first flexible sealing element 70 is provided with a first insertion hole 72 for inserting the lower end of the smoke transport tube 11, the corresponding support frame 60 is provided with a second insertion hole 62, and the support frame 60 is provided with an aerosol output channel 63 for connecting the atomizing surface 310 and the second insertion hole 62 in an airflow manner at a side opposite to the main housing 10. After installation, the complete suction airflow path is shown by an arrow R2 in fig. 3 and 4, the external air enters into the atomizing chamber 340 through the first air inlet 23 on the end cap 20, and then the generated aerosol is carried to the second jack 62 through the aerosol output channel 63 and then is output to the smoke transmission tube 11 through the first jack 72.

According to fig. 3 to 5, the atomizer 100 further comprises a third sealing element 80 positioned between the end cap 20 and the main housing 10 for providing a seal therebetween to prevent condensate or the like in the atomization chamber 340 from seeping out through the gap between the end cap 20 and the main housing 10.

As further shown in fig. 3 and 4, the third sealing element 80 is in the shape of a closed ring. In a preferred embodiment, the third sealing element 80 is made of a flexible material; such as silica gel.

To further facilitate assembly of the third sealing element 80, referring to fig. 3 to 6, the end cap 20 is provided with an assembly groove 24 extending in the circumferential direction of the end cap 20; the third seal member 80 is received and retained in the fitting groove 24.

Referring further to fig. 7 and 8, the third sealing element 80 includes:

the body portion 81, which is a generally flat ring, has a dimension d1 in the axial direction that is greater than a thickness dimension d2 in the radial direction of the body portion 81. In a particular implementation, the dimension d1 of the body portion 81 in the axial direction is approximately 1.5-2 mm, and the thickness dimension d2 of the body portion 81 in the radial direction is approximately 0.4-0.5 mm.

The body portion 81 has radially opposite inner 810 and outer 820 walls; wherein the inner wall 810 abuts the end cap 20 and the outer wall 820 abuts the main housing 10 during assembly. Meanwhile, a first rib 811 extending in the circumferential direction is provided on the inner wall 810, and a second rib 821 extending in the circumferential direction is provided on the outer wall 820. By the above first rib 811 and second rib 821, interference is formed with the end cap 20 and main housing 10 after assembly, and sealing is formed by tight pressing.

According to the preferred embodiment shown in fig. 6, after the third sealing member 80 is fitted into the fitting groove 24 of the end cap 20, the outer wall 820 of the body portion 81 is substantially flush with the outer surface of the end cap 20. That is, the depth of the fitting groove 24 is approximately equal to the thickness of the main body 81 plus the height of the first rib 811, so that the outer wall 820 of the main body 81 protrudes from the outer surface of the end cap 20 as little as possible during fitting, thereby preventing the occurrence of burring due to friction or the like during subsequent further fitting with the main housing 10.

In a preferred embodiment, the first rib 811 and/or the second rib 821 have a projection height of about 0.2 to 0.4mm.

Further in a preferred dimensioning, the dimension d1 of the main body portion 81 in the axial direction is greater than three times the projection height of the first bead 811 and/or of the second bead 821. The thickness dimension d2 of the main body portion 81 in the radial direction does not exceed the projection height of the first rib 811 and/or the second rib 821. Thereby preventing the third sealing member 80 from being flanged due to friction during further assembly of the end cap 20 with the main housing 10.

In the preferred embodiment shown in fig. 7 and 8, the number of the first ribs 811 is one, and the number of the second ribs 821 is two. And the first bead 811 and the second bead 821 are relatively staggered in the axial direction of the third seal member 80. The pressing portion of the third sealing member 80 by the first rib 811 and the pressing portion of the second rib 821 are not located at the same position by being relatively staggered, so that a higher interference amount can be obtained during assembly to improve the sealing effect.

As shown in fig. 7 and 8, the first rib 811 and/or the second rib 821 are preferably formed in a hemispherical, semi-ellipsoidal shape.

Meanwhile, in other more variation implementations, the number of the first ribs 811 and/or the second ribs 821 may be increased more; such as three or more. In a variable implementation, a greater number of first ribs 811 and second ribs 821 are alternately arranged in the axial direction of the main body portion 81; or the first rib 811 and the second rib 821 are relatively staggered in the axial direction of the main body portion 81; or the first bead 811 and the second bead 821 are aligned in the axial direction of the main body portion 81.

Fig. 9 shows a schematic structural view of a third sealing element 80a of yet another variant embodiment; two first ribs 811a arranged one behind the other in the axial direction are provided on the inner wall 810a of the main body portion 81a of the third sealing element 80 a; the outer wall 820a of the main body portion 81a is provided with a second rib 821a disposed near the center. The first rib 811a and the second rib 821 are relatively staggered in the axial direction of the main body portion 81 a.

Fig. 10 shows a schematic structural view of a third sealing element 80b of yet another embodiment; in the third sealing member 80b of this embodiment, the number of the first ribs 811b on the inner wall 810b and the second ribs 821b on the outer wall 820b are two; and are substantially aligned in the axial direction.

FIG. 11 shows a schematic structural view of a third sealing element 80c of yet another embodiment; the first ribs 811c on the inner wall 810c and the second ribs 821c on the outer wall 820c are each one in number and substantially aligned in the axial direction.

The above third sealing member 80/80a/80b/80c is also adapted to have a shape similar to an elliptical ring based on the flat cross-sectional design of the main housing 10 and the end cap 20 in the above embodiment. In other products, such as where the main housing 10 and end cap 20 are circular in cross-section, a third sealing element 80d, corresponding to the circular ring shape shown in fig. 12, may be employed to provide a seal therebetween.

In other variations, the above first sealing member 70 may also adopt the above third sealing member 80/80a/80b/80c configuration, thereby providing a seal between the support frame 60 and the main housing 10.

It should be noted that the preferred embodiments of the present application are shown in the specification and the drawings, but the present application is not limited to the embodiments described in the specification, and further, it will be apparent to those skilled in the art that modifications and variations can be made in the above description, and all such modifications and variations should be within the scope of the appended claims of the present application.
