Description

Atomizer, electronic atomization device and support 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 support 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 electronic atomising 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 known electronic atomizer, condensate generated in the atomizing chamber flows back into the air inlet passage, blocks the air inlet passage, or seeps to the power supply mechanism opposite to the air inlet passage.

According to a preferred embodiment shown in fig. 1, an atomizing assembly for atomizing a liquid substrate to produce an aerosol is provided within atomizer 100. According to the preferred embodiment shown in fig. 1, the atomizer 100 is provided with a second electrical contact 30 on the end opposite to the power supply mechanism 200 along the length direction, so that when at least a part of the atomizer 100 is received in the receiving chamber 270, the second electrical contact 30 makes electrical conduction by contacting and abutting with the first electrical contact 230, and the atomization assembly is supplied with power through the second electrical contact 30.

Fig. 2 shows a schematic structural diagram of an embodiment of the atomizer 100 in fig. 1, which includes:

a main housing 10; as shown in fig. 2 to 3, the main housing 10 is substantially flat, cylindrical or columnar; 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 at the proximal end 110; and the distal end 120 is used as an end to be coupled with the power supply mechanism 200, and the distal end 120 of the main housing 10 is open for installing necessary functional components inside the main housing 10. The open mouth of the distal end 120 of the main housing 10 is closed at the distal end 120 by the rigid support 40 after assembly.

In the embodiment shown in fig. 2 to 5, the second electrical contact 30 penetrates from the surface of the distal end 120 to the inside of the atomizer 100, and at least a part of the second electrical contact is exposed outside the atomizer 100, so as to be in contact with the first electrical contact 230 to form electrical conduction. Meanwhile, the holder 40 is further provided with an air intake passage 41 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 atomizing assembly generally comprises 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 an aerosol. In alternative implementations, the liquid-conducting element comprises flexible fibers, such as cotton fibers, non-woven fabrics, fiberglass strands, and the like, or comprises a porous material having a microporous structure, such as a porous ceramic; the heating element may be bonded to the wicking element by printing, deposition, sintering, or physical assembly, or may be wound around the wicking element.

Further in the preferred implementation shown in fig. 2-6, the atomizing assembly comprises: a porous body 21 for sucking and transferring the liquid matrix, and a heating element 22 for heating and vaporizing the liquid matrix sucked by the porous body 21. Specifically, the method comprises the following steps:

in the schematic cross-sectional structure shown in fig. 5, an aerosol output tube 11 is disposed in the main housing 10 along the axial direction, and defines an aerosol output channel; in practice, the aerosol output tube 11 extends at least partially within the reservoir 12, and the reservoir 12 is formed by the space between the outer wall of the aerosol output tube 11 and the inner wall of the main housing 10. A first end of the aerosol output tube 11 opposite the proximal end 110 is in communication with the mouthpiece a, and a second end of the aerosol output tube 11 opposite the distal end 120 is in air-flow communication with the atomizing surface 212 of the porous body 21, so as to deliver the aerosol generated and released by the heating element 22 as a liquid substrate to the mouthpiece a for inhalation.

And a reservoir chamber 12 defined between the outer wall of the aerosol output tube 11 and the inner wall of the main housing 10, closed at the end near the proximal end 110; and the reservoir 12 is open at the end toward the distal end 120, thereby allowing the liquid matrix to exit only from the open end.

Referring to the structure of the porous body 21 shown in fig. 3 to 6, the shape of the porous body 21 is configured to be a substantially, but not limited to, a block-shaped structure in the embodiment; according to a preferred design of the present embodiment, the porous body 21 is block-like in shape and is arranged substantially perpendicular to the longitudinal direction of the atomizer 100. Further, when assembled, the porous body 21 has opposing

surfaces

211 and 212. In use, surface 211 is in fluid communication with reservoir 12 and, in turn, serves as a wicking surface for wicking liquid matrix; the surface 212 is facing away from the reservoir 12 and is used as an atomizing surface for positioning the heating element 22 to atomize the liquid substrate to generate and release an aerosol.

In some specific implementations, the length dimension of the porous body 21 is about 8 to 15mm, the width dimension of the porous body 21 is about 4 to 8mm, and the thickness dimension of the porous body 21 is about 3 to 6mm.

As further shown in fig. 6, the porous body 21 has a porous portion 213 and a porous portion 214 extending between the surface 211 and the surface 212; and surface 211 is defined by porous portion 213 and surface 212 is defined by porous portion 214. Wherein a thickness dimension L1 of the porous portion 213 is greater than a thickness dimension L2 of the porous portion 214; the width dimension L3 of the porous portion 213 is greater than the width dimension L4 of the porous portion 214. In a specific implementation, the thickness dimension L1 of the porous portion 213 is approximately 2-4 mm, and the thickness dimension L2 of the porous portion 214 is approximately 1-2 mm. And, the width dimension L3 of the porous portion 213 is about 4 to 8mm, and the width dimension L4 of the porous portion 214 is about 3 to 6mm.

After assembly, the side wall of the porous portion 213 in the width direction is held against the holder 40; while the width-wise sidewalls of the porous portion 214 and/or the surface 212 are non-contacting or spaced from the support 40, it is advantageous to prevent heat transfer from the surface 212 and/or the heating element 22 to the support 40.

Of course, the heating element 22 is formed on the surface 212; and after assembly, the second electrical contact 30 makes electrical conduction against the heating element 22 to power the heating element 22.

Referring further to fig. 3-8, the support 40 of the atomizer 100 at least partially receives and retains the atomizing assembly. Specifically, the bracket 40 is made of a rigid material, such as plastic, ceramic, organic polymer, etc.; the support 40 is configured to extend substantially in the longitudinal direction of the nebulizer 100, and the support 40 has upper and lower ends that are opposite in the longitudinal direction. The upper end of the post-assembly support frame 40 extends into the main housing 10 and the lower end of the post-assembly support frame 40 is flush with the distal end 120 of the main housing 10. And, when assembled, at least the surface of the lower end of the support 40 is exposed at the distal end 120 of the main housing 10.

The support frame 40 has a connecting end 410 at a lower end, the connecting end 410 being at least partially convex with respect to the rest of the support frame 40, and being fixedly connected to the main housing 10 at the distal end 120 of the main housing 10 by the connecting end 410. Specifically, the connection end 410 is provided with a snap projection, and the inner wall of the main housing 10 is provided with a snap groove or the like near the distal end 120, so as to be fitted and connected with each other after assembly. The connection end 410 is extended perpendicular to the longitudinal direction of the bracket 40.

The bracket 40 further has

partition walls

420, 430 arranged at intervals in the longitudinal direction in this order. The

partition walls

420 and 430 each extend perpendicular to the longitudinal direction of the bracket 40; the

partition walls

420 and 430 are preferably implemented as thin sheets or plates.

A cavity 440 is defined between the partition wall 420 and the partition wall 430. After assembly, the atomizing assembly is received and retained within cavity 440. And, after assembly, the surface 212 of the porous body 21 to be used for atomization is adjacent to or faces the partition wall 430, and a space is maintained between the surface 212 and the partition wall 430. Further, after assembly, an atomization chamber 441 is formed by the portion of the cavity 440 between the surface 212 and the partition wall 430, and the aerosol atomized by the surface 212 is released into the atomization chamber 441 and then output to the aerosol output tube 11.

The partition wall 430 is provided with contact holes 47; when assembled, the second electrical contact 30 passes through the contact hole 47 and makes electrical contact against the heating element 22.

The contact bore 47 has an inner diameter of about 4-6 mm and the second electrical contact 30 has an outer diameter of about 3 mm; a space or gap remains between the second electrical contact 30 and the contact aperture 47 after assembly.

A cavity 450 is defined between the partition wall 430 and the connection end 410. When assembled, the cavity 450 is in communication with the cavity 440/aerosolizing chamber 441 via a gap or spacing between the second electrical contact 30 and the contact aperture 47. Then, in use, aerosol condensate within the cavity 440/atomising chamber 441 seeps into the cavity 450 from the gap or gap between the second electrical contact 30 and the contact aperture 47; the cavity 450 is in turn used as a condensate collection chamber to collect and retain aerosol condensate generated within the cavity 440/nebulization chamber 441.

The cavity 450 is open at both sides in the thickness direction of the bracket 40 and is closed after assembly to prevent the collected condensate from leaking out.

And further to fig. 5 to 8, the holder 40 is provided at the upper end with a plug hole 42 for fitting the lower end of the aerosol delivery tube 11 into the plug hole 42 in the fitting. And, the holder 40 has a liquid passage 44 extending from the upper end to the partition wall 420; when assembled, the liquid passage 44 is at least partially opposed to and connected to the surface 212 of the porous body 21 in the longitudinal direction of the holder 40. The liquid medium in reservoir 12 can be transferred to surface 212 of porous body 21 through liquid channel 44 as indicated by arrow R1 in fig. 4 and 5.

Referring to fig. 4 and 5, at least one side of the bracket 40 in the thickness direction is provided with a window 43; the cavity 440/nebulization chamber 441 is in air-flow communication with the plug aperture 42 via this window 43.

And the intake passage 41 is extended from the connection end portion 410 to the partition wall 430; the outside air enters the atomizing chamber 441 from the intake passage 41. And the inlet channel 41 is at least partially bounded by a tubular wall 411 within the cavity 450, as shown in figure 5, such that the inlet channel 41 and the cavity 450 are isolated from one another.

And as shown in fig. 4 and 7, the port 412 of the intake passage 41 on the partition wall 430 is higher than the other portion of the surface of the partition wall 430; it is advantageous to prevent aerosol condensate from the cavity 440/nebulization chamber/partition wall 430 from flowing to the inlet channel 41/port 412.

On the complete suction airflow path, as shown by the arrow R2 in fig. 4, 5 and 7, the external air enters the atomizing chamber 441 from the air inlet channel 41, and carries the generated aerosol across or around the porous body 21, and then enters the aerosol output tube 11 from the window 43 for output.

As further shown in fig. 8, the cavity 440 is formed with an opening 48 on one side and an opening 49 on the other side in the thickness direction of the bracket 40.

The sealing member 60 is made of a flexible material, such as silicone, an elastic polymer, or the like. The sealing member 60 has a cylindrical shape surrounding the holder 40; and the extension of the sealing element 60 is substantially the same as the extension of the carrier 40, so that the sealing element 60 can substantially completely surround the carrier 40 in length.

as shown by an arrow P2 in fig. 13, the sealing portion 62 of the sealing member 60 is bent to pass through the opening 66 and the opening 48 of the bracket 40 in this order, to extend into the cavity 440 of the bracket 40, and to abut against the partition wall 420 of the bracket 40, so that the assembled state of the sealing member 60 and the bracket 40 in fig. 14 is formed;

further according to the arrow R3 in fig. 15, the atomizing assembly/porous body 21 is loaded into the cavity 440 of the holder 40 through the opening 66 and the opening 48 in sequence, and abuts against the sealing portion 62; the second electrical contact 30 is finally inserted from the lower end of the holder 40 and supported against the atomizing assembly.

In this embodiment, the connecting arm 621 and the sealing portion 62 made of flexible materials can be selectively pulled out from the sealing element 60 through the opening 66 or extended into the inside from the sealing element 60 by pulling or bending.

In the above design of the sealing member 60, by moving the sealing portion 62 out or in, interference of the fitting of the holder 40 into the sealing member 60 is avoided or eliminated; and the placement of the seal 62 between the atomizing assembly and the dividing wall 420 of the carrier 40 is facilitated after the carrier 40 is assembled to the sealing member 60.

The column portion 67 has a length of about 3mm to 10mm, and about; the second section 820 extends longitudinally to a length of about 3 to 6mm in outside diameter. And, the inner surface of the vent hole 45 is provided with an axially extending groove 451 to maintain a gap or air gap therebetween after they are assembled. Accordingly, air in the nebulizing chamber 441 can sequentially pass through the groove 46, the vent hole 45, and the gap or air gap between the columnar portion 67, as indicated by an arrow R3 in fig. 4 or 7, and enter the reservoir 12, so as to supplement air into the reservoir 12 to relieve the negative pressure in the reservoir 12.

In practice, the groove 451 has a width of about 0.5mm and a depth of about 0.5 mm; the cross-sectional area of the air passage defined by the grooves 451 is made smaller than 1mm ² To prevent leakage of the liquid matrix from the air channel.

And, the number of the grooves 451 may include plural, and be arranged at intervals in the circumferential direction. Or in yet other variations, the groove 451 can also be provided on the outer surface of the column portion 67.

Specifically, the end wall 610 of the seal member 60 defines a wall 671 of the fluid conducting hole 65, and the cylindrical portion 67 extends from the wall 671. And the sealing member 60 also has an escape hole 672 at a position closer to the end than the liquid guide hole 65 in the width direction for allowing air entering from a gap or an air gap between the air vent hole 45 and the columnar portion 67 to enter the liquid storage chamber 12 through the escape hole 672.

And in a particular implementation, the extension of the opening 66a in the longitudinal direction of the first sealing element 60a is such as to cover the window 43a of the support portion 40 a; or the opening 66a is opposed to or coincides with the window 43a of the support portion 40a at least partially in the thickness direction of the support portion 40 a; which in turn is advantageous to prevent the window 43a from being obstructed or clogged to affect the output of aerosol from the window 43 a.

In a further more preferred embodiment, as shown in fig. 20, 21, 23, the support portion 40a is further provided with a vent hole 45a near the upper end; the lower end of the air vent 45a is in air flow communication with the atomizing chamber 441a through a recess 46a in the outer surface of the support portion 40a, and the upper end of the air vent 45a is directed toward the reservoir 12a. Correspondingly, the first sealing element 60a also has a cylindrical portion 67a, which is bounded by the end wall 610 a. According to the illustration in the figure, the columnar portion 67a is columnar in shape; after assembly, the cylindrical portion 67a extends from the upper end into the vent hole 45 a.

In practice, the ventilation holes 45a have an extension length of about 3 to 10 mm; the vent hole 45a has an inner diameter of 3 to 6mm. The column portion 67a has a length of about 3mm to 10mm and an outer diameter of about 3mm to 6mm. And, the vent holes 45a are provided on their inner surfaces with axially extending grooves to maintain a gap or air gap therebetween after they are assembled. Accordingly, air in the atomizing chamber 441a can sequentially enter the reservoir 12a through the groove 46a, the vent hole 45a and the gap or air gap between the cylindrical portion 67a as indicated by an arrow R3 in fig. 21 and 23, so as to supplement air into the reservoir 12a to relieve the negative pressure of the reservoir 12a.

As further shown in fig. 22 and 23, the vent hole 45a, the cylindrical portion 67a of the first sealing member 60a, are all offset from the liquid passage 44a. The cylindrical portion 67a extends from the end wall 610a of the first seal member 60 a. Specifically, the end wall 610a of the first seal member 60a defines a wall 671a of the liquid guide hole 65a, and the cylindrical portion 67a extends from the wall 671 a. And the first sealing member 60a also has an escape hole 672a closer to the end in the width direction than the liquid guide hole 65a for air entering from a gap or air gap between the air vent hole 45a and the columnar portion 67a to enter the reservoir chamber 12a through the escape hole 672 a. In implementation, the relief holes 672a are curved arcs. And the escape hole 672a is isolated from the drain hole 65 a; and the cross-sectional area of the escape hole 672a is smaller than the area of the liquid guide hole 65 a.

As further shown in fig. 17 and 20, the electronic atomizer 100a further includes:

a flexible second sealing member 70a, the second sealing member 70a being located within the cavity 440a of the support portion 40a after assembly, surrounding the atomizing assembly/porous body 21a; to provide a seal between the atomizing assembly/porous body 21a and the support portion 40a.
