In order to make the present utility model better understood by those skilled in the art, the following description of the present utility model will be made in detail with reference to the accompanying drawings in the embodiments of the present utility model. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the utility model. All other embodiments, based on the embodiments of the utility model, which a person skilled in the art would obtain without making any inventive effort, are within the scope of the utility model.

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

Referring to fig. 1 and 2, the present embodiment provides an electronic atomization device 1, and the electronic atomization device 1 may include: a power supply assembly 20, a heating device 10 and a housing 30.

The housing 30 may be used to protect the power supply assembly 20 and the heating device 10, and in this embodiment, the housing 30 may be provided with an insertion hole 310, and the aerosol-generating substrate 2 may be inserted into the heating device 10 inside the housing 30 through the insertion hole 310 for heating and atomizing. The specific shape of the housing 30 is not limited in the embodiment of the present application, and for example, the housing 30 may have a rectangular parallelepiped structure subjected to a rounding process, a cobble-like structure, or the like.

In this embodiment, the housing 30 may be made of metal, plastic, ceramic, or the like. The metal shell 30 has the advantages of being firm and durable, resistant to high temperature, good in heat radiation performance, and good in touch sense and texture. The plastic housing 30 has the advantage of being lightweight and easily manufactured into various shapes, and can achieve more design freedom. In addition, the plastic housing 30 is generally less expensive and more economical for mass production. Ceramic materials can provide unique textures and attractive design. In addition, the ceramic housing 30 has a strong adaptability to temperature changes, and can achieve a better thermal protection effect. It will be appreciated that the embodiments of the present application are not limited to the specific materials of the housing 30, and the user may choose according to the actual situation, for example, may choose a ceramic housing 30.

The heating means 10 may be arranged inside the housing 30 for heating the aerosol-generating substrate 2. Specifically, the heating device 10 may include: a heating tube 110, an inner reflecting layer 120, a support 130, and an outer reflecting layer 140.

Referring to fig. 3, the heating tube 110 forms a heating cavity 111, and an opening 112 may be disposed at one end of the heating tube 110, and the opening 112 may be in communication with the insertion hole 310, so as to facilitate the aerosol-generating substrate 2 to be inserted into the heating cavity 111 of the heating tube 110 for heating and atomizing. It should be noted that, the specific structure of the heating tube 110 is not limited in this embodiment, for example, the cross section of the heating tube 110 may be circular, square or other polygonal shape, and the present utility model is not limited herein.

Referring to fig. 4 and 5, the internal reflection layer 120 may be disposed around the heat generating tube 110, and the heat generating tube 110 is surrounded by the internal reflection layer 120, so that the heat generated by the heat generating tube 110 is reflected back into the heat generating tube 110 by the internal reflection layer 120, and meanwhile, the energy emitted from the heat generating tube 110 to the outside of the heating device 10 is reduced, the user is prevented from being scalded, and the heat utilization rate of the heat generating tube 110 is improved.

The internal reflection layer 120 has the lowest possible thermal conductivity and the lowest possible thickness on the premise of low emissivity.

Emissivity refers to the radiant power emitted from the surface of the object, and an excessive emissivity of the object may cause it to radiate heat energy faster, that is, if the emissivity of the internal reflection layer 120 is excessive, the temperature emitted from the heating tube 110 to the internal reflection layer 120 may quickly pass through the internal reflection layer 120, so that the internal reflection layer 120 will hardly have an effect of reflecting heat, and in this embodiment, the emissivity of the internal reflection layer 120 may be any value of more than 0 and less than or 0.3, for example, the emissivity of the internal reflection layer 120 may be 0.1, 0.25, 0.3, etc.

Since thermal conductivity refers to the ability of a substance to conduct heat, it represents the flow of heat per unit area per unit time, which is a physical quantity that measures the heat transfer properties of a substance. That is, if the thermal conductivity of the inner reflective layer 120 is too high, the heat conduction speed of the inner reflective layer 120 increases, and the temperature emitted from the heat pipe 110 to the inner reflective layer 120 is quickly transferred from the inner reflective layer 120, which is disadvantageous to the heat pipe 110 due to the heat reflected by the inner reflective layer 120. In this embodiment, the thermal conductivity of the internal reflection layer 120 may be 400W/(m·k) or less, and may be, for example, 100W/(m·k), 200W/(m·k), 350W/(m·k), 400W/(m·k), or the like, without limitation.

It will be appreciated that, to control the overall size of the heating device 10, the thickness of the inner reflective layer 120 may be less than or equal to 0.3mm, and if the thickness of the inner reflective layer 120 is too large, the overall size of the heating device 10 may be too large, which may further result in the electronic atomization device 1 being too large, which is not beneficial for users to hold. Accordingly, in the present embodiment, the thickness of the internal reflection layer 120 may be set to 0.1mm, 0.2mm, 0.3mm, etc., without limitation.

The supporting member 130 may be disposed around the heat generating tube 110, and the supporting member 130 may be a polystyrene foam board (EPS board), an extruded polystyrene board (XPS board), or the like. The plates have a closed cell structure, so that heat transfer can be effectively isolated, and scalding of a user is avoided.

It is understood that in the present embodiment, the thermal conductivity of the support 130 may be set to be less than or equal to 7W/(m·k), and may be, for example, 2W/(m·k), 4W/(m·k), 6W/(m·k), 7W/(m·k), or the like, without limitation. The thickness of the support 130 may be set to be less than or equal to 2mm, for example, 1mm, 1.5mm, 2mm, etc., without limitation.

In this embodiment, the inner reflective layer 120 is connected to the surface of the supporting member 130 facing the heating tube 110 and is adjacent to the heating tube 110, so that the distance between the inner reflective layer 120 and the heating tube 110 is shorter, and heat emitted by the heating tube 110 can be better reflected back to the heating tube 110, thereby avoiding scalding the user and improving the heat utilization rate of the heating tube 110.

Further, the inner reflective layer 120 may be adhered to the surface of the supporting member 130 facing the heating tube 110, and it should be noted that the inner reflective layer 120 may also be plated on the supporting member 130, so that the installation of the heating device 10 may be simplified.

The outer reflective layer 140 may be disposed on a surface of the supporting member 130 far away from the inner reflective layer 120, and the outer reflective layer 140 may be used for absorbing heat emitted by the heat-emitting tube 110 and passing through the supporting member 130, and reflecting the heat back, so that the user is prevented from being scalded, and the heat utilization rate of the heat-emitting tube 110 is improved.

In one embodiment, the outer reflective layer 140 may be made of the same material or structure as the inner reflective layer 120, and reference may be made to the inner reflective layer 120 for details, which are not described herein.

In one embodiment, the outer reflective layer 140 may be an aluminum foil tube, which has good heat insulating properties, and which can effectively block heat transfer. Meanwhile, the density of aluminum is relatively low, so that the aluminum foil tube has the characteristic of light weight, the overall weight of the heating device 10 can be further reduced, in addition, the aluminum foil material has good corrosion resistance, and is not easily influenced by oxidation, corrosion and corrosive media, so that the service life of the heating device 10 can be effectively guaranteed.

The thickness of the insulating layer 150 may be set to be greater than or equal to 0.5mm, and it should be noted that, too small thickness of the insulating layer 150 will hardly have an insulating effect, and meanwhile, the thickness of the insulating layer 150 should not be too large, if the result of the insulating layer 150 is too large, the overall thickness of the heating device 10 will be too large, and further, the size of the electronic atomization device 1 will be too large, which is not beneficial for users to hold.

That is, a gap may be provided between the support 130 and the insulation layer 150, and since there is little direct contact between the insulation layer 150 and the support 130, the speed of heat transferred from the support 130 to the insulation layer 150 may be slowed down, and thus the gap may serve to transfer heat that slows down heat dissipation by the heat pipe 110.

In addition, the supporting member 130 may be connected to the heat insulating layer 150 through the separation block 132, that is, the supporting member 130 and the heat insulating layer 150 may be detachably connected, that is, the supporting member 130 and the heat insulating layer 150 may be assembled together before the entire heating apparatus 10 is assembled, so that the assembly of the heating apparatus 10 may be simplified.
