Description

Insulation material for aerosol generating device and aerosol generating device including the same

The present disclosure relates to an aerosol generating device including an insulating material for the aerosol generating device. More specifically, it relates to a heat insulating material for an aerosol generating device designed to prevent deterioration in insulation performance as liquid droplet sidestream smoke is absorbed, and an aerosol generating device including the same.

In recent years, there has been an increasing demand for alternative smoking articles that overcome the disadvantages of traditional cigarettes. For example, the demand for an aerosol generating device (e.g. cigarette type electronic cigarette) that generates aerosol by electrically heating a cigarette is increasing, and accordingly, research on an electrically heated aerosol generating device is being actively conducted.

As a way to increase energy efficiency, some electrically heated aerosol generators use insulation materials such as cerakwool and airgel. However, when the sidestream smoke penetrating into the inside of the device and forming liquid droplets is absorbed by the heat insulating material, the thermal conductivity of the heat insulating material is increased and the heat insulating performance is remarkably deteriorated, and eventually the function as a heat insulating material is lost.

FIG. 1 is a view for explaining a problem in which the performance of an insulator is deteriorated due to sidestream smoke, and illustrates smoking a cigarette 23 through an aerosol generating device 20. Referring to FIG.

As illustrated in FIG. 1 , smoking may be performed by heating the cigarette 23 by the heater 22 disposed around the cigarette 23 . In this case, an insulator 21 may be disposed around the heater 22 to reduce heat energy loss of the heater 22 .

During smoking, mainstream smoke and sidestream smoke may be generated from the cigarette 23 .

At this time, when the internal temperature of the aerosol generating device 20 drops, the sidestream smoke becomes droplets, and a phenomenon in which the heat insulating material 21 absorbs the droplets of sidestream smoke may occur. In addition, as this phenomenon continues, the thermal conductivity of the heat insulating material 21 gradually increases, and eventually loses its function as a heat insulating material.

Hereinafter, the technical idea of the present disclosure for solving the above problems will be described in detail through various embodiments.

2 shows an exemplary structure of an insulator 10 for an aerosol generating device according to some embodiments of the present disclosure.

As shown in FIG. 2 , the heat insulating material 10 may include a heat insulating core material 12 including a heat insulating material and a waterproof film 11 disposed on an outer surface of the heat insulating core material 12 . For example, the first waterproof film 11-1 is disposed (e.g. laminated) on the first outer surface of the insulating core material 12, and the second waterproof film 11-2 is placed on the second outer surface opposite to the first outer surface. ) can be arranged (e.g. stacked). The waterproof film 11 may play a role of preserving the heat insulation performance of the heat insulating core material 12 by blocking external moisture (eg, liquid droplet sidestream smoke) and air flow.

Here, arranging the waterproof film 11 on the insulating core material 12 means not only attaching the waterproof film 11 using an adhesive material, but also everything that causes the insulating core material 12 and the waterproof film 11 to come into close contact. method can be covered. For example, vacuum filling of the insulating core material 12 between the waterproof films 11-1 and 11-2 may also be included in the meaning of the arrangement.

In some embodiments, the waterproof film 11 may be disposed so that the insulating core 12 is sealed (sealed) from the outside. For example, as illustrated in FIG. 1 , when the first waterproof film 11-1 and the second waterproof film 11-2 are disposed on each outer surface of the insulating core material 12, the first waterproof film ( 11-1) and both ends 13-1 and 13-2 of the second waterproof film 11-2 may be bonded (sealed). In this case, the insulating core material 12 is completely sealed from the outside, so that external moisture or airflow can be prevented from permeating. For example, a problem in which moisture or air current penetrates between the insulating core material 12 and the waterproof film 11 and the performance of the insulating core material 12 is deteriorated can be prevented in advance.

The material of the insulating core 12 may be various, which may vary depending on the embodiment.

In some embodiments, the material of the insulating core 12 may include at least one of airgel, silica gel, pearlite (eg, close cell type), cerakwool, and hollow silica. .

In some embodiments, the material of the insulating core 12 may include a hollow bead (eg hollow ceramic bead, hollow silica bead). For example, a porous structure including a plurality of hollow beads may be used as the insulating core material 12 . This embodiment will be described in more detail with reference to FIGS. 3 and 4 later.

However, the material of the insulating core 12 is not limited to the above examples, and other types of insulating materials may be applied to the insulating core 12 .

In addition, the material of the waterproof film 11 may also vary, and this may also vary depending on the embodiment.

In some embodiments, the waterproof film 11 may be a polyimide film. The polyimide film not only blocks moisture absorption, but also has excellent heat resistance, and thus may be suitable as an insulator disposed in a film heater.

In some other embodiments, the waterproof film 11 may be implemented as a film of another material having waterproof properties. For example, the material of the waterproof film 11 is polyetheretherketone (PEEK), polyamidimide (PAI), polyphenylen sulfide (PPS), polyphenylsulfone (PPSU) Among polysulfone (PSU), polyethersulfone (PES), polyetherimide (PEI), polytetrafluoroethylene (PTFE), and polyvinylidene fluoride (PVDF) may contain at least one. However, it is not limited to the above examples.

On the other hand, since the waterproof film 11 and/or the insulating core 12 are disposed inside the aerosol generating device (e.g. 30-1, 30-2 in FIG. 5 or 6), it is preferable to implement a material having high heat resistance. can For example, it may be preferable that the waterproof film 11 and/or the insulating core material 12 be made of a material having a heat resistance of about 200 degrees or more.

So far, the heat insulating material 10 for an aerosol generating device according to some embodiments of the present disclosure has been described with reference to FIG. 2 . According to the foregoing, since the waterproof film 11 is provided on the outer surface of the insulator 10, the absorption of liquid droplet sidestream smoke can be blocked. Accordingly, the performance of the insulator 10 may be continuously maintained. Hereinafter, the hollow bead-based heat insulating material 10 will be described with reference to FIGS. 3 and 4 .

3 illustrates a hollow bead-based insulator 10 according to some embodiments of the present disclosure.

As shown in FIG. 3, the heat insulating material 10 may include a heat insulating core material 12 and a waterproof film 11 disposed on an outer surface, and a porous structure formed by a plurality of hollow beads is a heat insulating core material 12 can be used as The waterproof film 11 may block penetration of moisture or air flow through pores on the outer surface of the insulating core material 12 .

The porous structure 12 may be formed by packing a plurality of hollow beads. For example, as shown in FIG. 4 , the porous structure 12 may be formed by sphere packing and firing a plurality of hollow beads 30 . The sphere packing method may be, for example, Body-Centered Cubic (BCC), Face-Centered Cubic (FCC), etc., but the scope of the present disclosure is not limited to the above example. .

The material of the hollow bead may be preferably a ceramic bead having low thermal conductivity. In addition, the ceramic beads may include, for example, ceramic silica beads and ceramic alumina beads. However, the scope of the present disclosure is not limited to the examples listed above, and hollow beads of other materials having low thermal conductivity may be used.

In some embodiments, the hollow bead may have a diameter between 75 μm and 500 μm. Preferably, the hollow beads may have a diameter of 100 μm to 450 μm, 150 μm to 450 μm, or 150 μm to 400 μm. Within this numerical range, excellent insulation performance and ease of manufacture can be secured. For example, it may be preferable that the diameter of the hollow bead is 75 μm or more, because the heat insulation performance of the porous structure improves as the size of the hollow bead increases. In addition, it may be preferable that the diameter of the hollow bead is 500 μm or less, because the larger the size of the hollow bead, the larger the surface curvature, making it difficult to place the waterproof film 11 in close contact.

Also, in some embodiments, the diameter distribution of the plurality of hollow beads may have an error range of less than 30% compared to the average diameter. Preferably, the diameter distribution of the plurality of beads may have an error range within 25%, 23% or 21%. More preferably, the diameter distribution of the plurality of beads may have an error range within 20%, 18%, 16%, 14%, 12% or 10%. Even more preferably, the diameter distribution of the plurality of beads may have an error range within 8%, 6% or 5%. Since it is not easy to continuously manufacture beads having the same diameter, the cost and difficulty required for manufacturing the porous structure 12 within this error range can be greatly reduced.

Meanwhile, according to some embodiments of the present disclosure, an initial porous structure is formed by packing hollow beads of a first size, and a final porous structure is formed by packing hollow beads of a second size on the outer surface of the initial porous structure. You may. In this case, the second size may have a smaller value than the first size. In this case, since the pore size of the outer surface of the porous structure is reduced, the waterproof film 11 can be easily disposed. In addition, by forming the initial porous structure with sufficiently large hollow beads, the performance of the insulator 10 can be improved.

So far, the method for manufacturing the hollow bead-based insulator 10 has been described through the packing and firing process, but in some other embodiments of the present disclosure, the hollow beads are densely filled between the waterproof films 11. The heat insulating material 10 may be manufactured in such a way. In this case, since it does not undergo a firing process, the insulator 10 can be manufactured in a flexible film form, and the manufactured insulator 1 wraps around a heater (eg, the film-type heater 33 illustrated in FIG. 5) or is attached to the heater. It can be used well in this way (see Fig. 5).

The hollow bead-based insulator 10 according to some embodiments of the present disclosure has been described so far with reference to FIGS. 3 and 4 . Hereinafter, an embodiment of the above-described method of disposing the heat insulating material 10 will be described with reference to FIGS. 5 and 6 .

FIG. 5 illustrates an aerosol generating device 30-1 to which the method for arranging an insulator according to the first embodiment of the present disclosure is applied.

As illustrated in FIG. 5 , in this embodiment, the heat insulating material 10 is attached to the heater 33 to improve the heating efficiency of the heater 33 . For example, the insulator 10 is made in the form of a flexible film, the heater 33 is also implemented as a film heater, and the manufactured film insulator 10 is attached to the film heater 33 by thermal fusion or adhesive. can Hereinafter, the present embodiment together with the components of the aerosol generating device 30-1 will be described in more detail.

As shown in FIG. 5, the aerosol generating device 30-1 may include an outer housing 31, an inner housing 32, a heater 33, and an insulator 10 attached to the heater 33. . However, only components related to the embodiment of the present disclosure are shown in FIG. 5 . Accordingly, those of ordinary skill in the art to which this disclosure belongs may know that other general-purpose components may be further included in addition to the components shown in FIG. 5 . For example, although not shown, the aerosol generating device 30-1 includes a battery (not shown) that supplies power to the heater 33, components of the aerosol generating device 30-1 (e.g. heater 33, battery etc.) may further include a control unit (not shown) for controlling the operation. Hereinafter, each component of the aerosol generating device 30-1 will be described.

The outer housing 31 may form the exterior of the aerosol generating device 30-1. Also, the outer housing 31 may form an accommodation space for accommodating the aerosol-generating article 2 . The aerosol-generating article 2 may generate an aerosol by being electrically heated in a state inserted into the accommodation space, and the generated aerosol may be inhaled by the user through the mouth. The aerosol-generating article 2 may be, for example, a cigarette, but the scope of the present disclosure is not limited to this example.

Portion 21 of aerosol-generating article 2 may include a solid aerosol-generating substrate. The solid aerosol-generating substrate may be heated by heater 33 to form an aerosol.

Next, the inner housing 32 may define the internal structure of the aerosol generating device 30-1. The material, arrangement, etc. of the inner housing 32 may be variously modified according to the internal design of the aerosol generating device 30-1.

In some embodiments, at least a portion of the inner housing 32 may be implemented with an insulating material. In this case, heat (energy) loss to the outside of the aerosol generating device 30-1 can be more effectively blocked.

Next, the heater 33 can heat the aerosol-generating article 2 accommodated in the accommodating space. For example, the heater 33 may be disposed to enclose at least a portion of the accommodating space to heat the aerosol-generating article 2 .

As mentioned above, the heater 33 may be implemented as a film type heater. In addition, a heat insulating material 10 may be attached to the heater 33 . The insulator 10 may be attached to the heater 33 by thermal fusion or adhesive, but the scope of the present disclosure is not limited thereto. In addition, the insulator 10 may be manufactured in the form of a flexible film and attached to a desired portion of the heater 33 . For example, the insulator 10 may be attached in a form surrounding the entire heater 33 or may be attached only to one portion of the heater 33 . As a more specific example, the heat insulator 10 may be attached in a form surrounding the surface of the heater 33 opposite to the aerosol generating article 2 (see FIG. 5). In this case, since the heat of the heater 33 can be concentrated toward the aerosol-generating article 2, the heating efficiency of the heater 33 can be further improved.

So far, the aerosol generating device 30-1 according to the first embodiment of the present disclosure has been described with reference to FIG. 5 . According to the above description, heating efficiency of the heater 33 may be improved by attaching the heat insulating material 10 to the film heater 33 . Specifically, heat from the heater 33 is concentrated on the aerosol-generating article 2 by the heat insulating material 10, so that the heating efficiency of the heater 33 is improved, and the taste of the aerosol-generating article 2 (particularly, the initial taste) is improved. taste) can also be improved. In addition, as the heating efficiency is improved, the preheating time of the aerosol generating device 30-1 can be shortened and power consumption can be greatly reduced. Furthermore, since the space occupied by the heat insulating material 10 is minimized, there is also an advantage that the aerosol generating device 30-1 can be manufactured more compactly.

In addition, since the insulator 10 is attached to the heater 33 and disposed in the aerosol generating device 30-1, a separate process for arranging the insulator 10 does not need to be performed. For example, when manufacturing the heater 33, the heater 33 and the heat insulating material 10 can be manufactured integrally by attaching the heat insulating material 10, and the manufacturing process can be simplified by disposing it in the aerosol generating device 30-1. have.

Hereinafter, an aerosol generating device 30-2 according to a second embodiment of the present disclosure will be described with reference to FIG. 6 .

More specifically, the insulator 10 may be disposed between the heater 33 and the inner housing 32, and an air gap may be positioned between the insulator 10 and the heater 33.

The air gap prevents heat transfer, thereby minimizing heat loss to the outside of the aerosol generating device 30 - 2 and improving the effect of the heat insulating material 10 . However, in this embodiment, since the process of disposing the heat insulating material 10 must be performed separately, the manufacturing process may be more complicated than that of the previous embodiment.

So far, a heat insulating material disposing method according to some embodiments of the present disclosure has been described with reference to FIGS. 5 and 6 . According to the foregoing, the heating efficiency of the heater 33 can be improved by disposing the heat insulating material 10 inside the aerosol generating devices 30-1 and 30-2. Furthermore, the heat of the heater 33 is effectively concentrated on the aerosol-generating article 2 via the heat insulating material 10, thereby improving the taste (particularly, the initial taste) of the aerosol-generating article 2, and the aerosol-generating device ( The preheating time of 30-1 and 30-2) can be shortened, and power consumption can be greatly reduced.
