Detailed Description

The present application is described in further detail below with reference to the accompanying drawings by way of specific embodiments. Wherein like elements in different embodiments are numbered alike in association. In the following embodiments, numerous specific details are set forth in order to provide a better understanding of the present application. However, one skilled in the art will readily recognize that some of the features may be omitted, or replaced by other elements, materials, or methods in different situations. In some instances, some operations associated with the present application have not been shown or described in the specification to avoid obscuring the core portions of the present application, and may not be necessary for a person skilled in the art to describe in detail the relevant operations based on the description herein and the general knowledge of one skilled in the art.

Furthermore, the described features, operations, or characteristics of the description may be combined in any suitable manner in various embodiments. Also, various steps or acts in the method descriptions may be interchanged or modified in a manner apparent to those of ordinary skill in the art. Thus, the various orders in the description and drawings are for clarity of description of only certain embodiments, and are not meant to be required orders unless otherwise indicated.

The numbering of the components itself, e.g. "first", "second", etc., is used herein merely to distinguish between the described objects and does not have any sequential or technical meaning. The terms "coupled" and "connected," as used herein, are intended to encompass both direct and indirect coupling (coupling), unless otherwise indicated.

According to the atomization device, the heat insulation piece with the multi-layer cavity structure is arranged on the periphery of the heating body in a surrounding mode; on one hand, the heat insulation piece can prevent the heat emitted by the heating element from being transferred to the outer shell, so that the heat loss can be effectively reduced, and the problem that the outer shell is easy to scald hands and the like to influence the user experience due to the fact that a large amount of heat is absorbed can be avoided; on the other hand, the heat insulation piece can absorb part of heat emitted by the heating element so as to play a role in energy accumulation and heat preservation on the heating element, and the heat utilization rate can be improved, and meanwhile, an advantage can be created for reducing the power consumption of the atomizing device.

For a clearer detailed description of the atomizing device, terms such as "axial of the insulation", "radial of the insulation", etc. are introduced herein; where "axial direction of the insulation element" and "radial direction of the insulation element" are two different directions defined based on the overall profile shape or configuration of the insulation element, whereas in this application the overall profile of the insulation element is generally a tubular structure, "axial direction of the insulation element" is understood to be the direction in which the axis of the insulation element is located or extends, and "radial direction of the insulation element" is understood to be the direction perpendicular to the axis of the insulation element.

Referring to fig. 1 to 5, an embodiment provides an atomizing device, such as a heating non-combustion atomizing device, which includes an outer housing 10, a heating body 20, a heat insulator 30, and other components as needed, which will be described in detail below.

Referring to fig. 1 to 3, the outer housing 10 may be understood as a collection of related functional components constituting an outer contour structure of the atomizing device, for example, the outer housing 10 may be constructed by combining an upper housing part 11, a lower housing part 12, a control part 13 including a power source, and the like; the user can carry, use and operate the atomizing device by holding the outer housing 10. In general, a structural space for accommodating the heat generating body 20, the heat insulating member 30, the medium to be atomized and the related functional members, and an air flow passage, an air inlet, an air outlet, etc. through which the air flow can flow are provided in the outer case 10.

Referring to fig. 2 to 5, the heat insulator 30 is mainly used for establishing a heat insulation mechanism between the outer casing 10 and the heating element 20 to prevent heat generated by the heating element 20 from being transferred to the outer casing 10; the heat insulating member 30 is installed in the outer casing 10, and has a generally tubular overall contour, wherein for convenience of distinction and description, a pipe space of the heat insulating member 30 is defined as a heating channel 30c, and a pipe sidewall surrounding the heating channel 30 is defined as a heat insulating sidewall; it will also be appreciated that the insulating side walls are circumferentially disposed about the axis of the insulating member 30 and form the heating channel 30 c. And the heat-generating body 20 is located in the heating channel 30c to form a structure in which the heat-insulating member 30 is distributed around the heat-generating body 20.

Referring to fig. 2 to 4, the heat-insulating side wall of the heat-insulating member 30 adopts a multi-layered hollow structure having three closed chambers arranged in a spaced apart relationship along the radial direction of the heat-insulating member 30; for ease of distinction and description, the central one of the three-layer enclosed chambers is defined as a first chamber 30a, and the other two of the three-layer enclosed chambers are defined as a second chamber 30b; wherein the first chamber 30a is filled with a heat absorbing medium, such as a liquid or semi-solid medium with larger specific heat capacity, for example, acetone, isopropanol, dimethylacetamide, water, grease, etc.; according to actual requirements, inert gas can be filled in the second chamber 30b; the internal pressure of the second chamber 30b may also be reduced by lowering the internal pressure of the second chamber 30b such that the internal pressure of the second chamber 30b is lower than the ambient pressure outside the insulated sidewall, e.g., the internal pressure of the second chamber 30b is a vacuum pressure.

In practice, the heat-generating body 20 may be of a porous structure to heat the air flow flowing through or past the heat-generating body 20, thereby baking and heating the medium to be atomized placed in the outer casing 10 by means of the formed hot air flow; or according to the specific structure of the medium to be atomized, the atomizing mode of the atomizing device, and the like, the heating body 20 can also adopt a structure which is adaptive to realize the baking and heating of the medium to be atomized through the direct contact with the medium to be atomized.

Based on this, when the atomizing device is operated or the heating element 20 generates heat, a part of heat is transferred in the radial direction of the heat insulator 30 by radiation, convection, conduction, or the like, but is affected by the inert gas or the lean air (i.e., the low pressure environment) in the second chamber 30b, so that the heat is less likely to be transferred to the outer case 10 through the heat insulator 30, and the heat insulator 30 has an effect of blocking the transfer of heat; thus, only a small portion of the heat can be eventually dissipated through the outer case 10.

Meanwhile, a part of heat is transferred along the heat insulation side wall along the axial direction of the heat insulation member 30, on one hand, the length of the heat insulation side wall along the axial direction of the heat insulation member 30 is longer, which is equivalent to prolonging the heat transfer path, so that the heat transfer or heat exchange efficiency is reduced; on the other hand, when heat is transferred to the two ends of the heat insulating member 30 in the axial direction, the heat absorbing medium in the first chamber 30b absorbs heat, so that not only can the transfer of heat to the outer casing 10 be further reduced, but also the heat absorbed by the heat absorbing medium is equivalent to forming a heat insulating layer on the periphery of the heating element 20, so as to play a role in energy accumulation and heat insulation, so that most of the heat generated by the heating element 20 can act on the flowing air flow or the medium to be atomized, and conditions are created for reducing the power consumption of the atomizing device while improving the heat utilization rate.

In addition, the heat insulator 30 prevents heat transfer from being blocked, and other relevant components in the outer case 10 from being damaged by high temperature.

It should be noted that, the medium to be atomized described herein may be solid medium materials such as medicinal materials, perfume, tobacco, etc., semi-solid medium materials such as medicinal paste, tobacco paste, etc., or liquid medium materials such as liquid medicine, physiological saline, liquid extract, tobacco tar, etc.; typically, the medium to be atomized may be packaged in a shaped form from a wrapper or may be contained within a container (e.g., an atomizing cup) based on the form of the material.

In other embodiments, the number of closed cells may be two, one as the first cell 30a and the other as the second cell 30b; of course, the number of closed cells may be set to four, five or other greater numbers, at least one of which serves as the first cell 30a and at least one of which serves as the second cell 30b, to further enhance the heat transfer barrier effect of the entire thermal shield 30.

In one embodiment, referring to fig. 4, the heat insulation member 30 is in an integral structure, and may be made of materials with high temperature resistance and good heat insulation performance, such as glass fiber, polyurethane plastic, etc.; specifically, the insulating side wall of the insulating member 30 includes two axial end wall portions 31 and four circumferential side wall portions 32; wherein two axial end wall portions 31 are spaced apart from each other in the axial direction of the heat insulator 30, and four circumferential side wall portions 32 are spaced apart from each other in the radial direction of the heat insulator 30; and each of the circumferential side wall portions 32 extends at both ends in the axial direction of the heat insulating member 30 and is connected to the axial end wall portion 31 of the corresponding end, respectively; accordingly, corresponding closed chambers can be formed between the adjacent circumferential side wall portions 32 and the axial end wall portions 31.

In other embodiments, portions of the circumferential side wall portion 32 and the axial end wall portion 31 may also be configured for removable connection. Alternatively, the heat insulating member 30 may be in a split assembly structure, for example, the heat insulating member 30 includes a plurality of sleeves, and each sleeve has at least one closed chamber disposed in a sidewall thereof; the plurality of bushings are integrally formed in a coaxial insert or close-fitting sleeve to construct the insulation 30 having a generally tubular overall profile.

In one embodiment, referring to fig. 3, with a predetermined gap between the heat-insulating side wall of the heat-insulating member 30 (specifically, the circumferential side wall portion 32 closest to the heat-generating body 20) and the heat-generating body 20, it is understood that the heat-generating body 20 is disposed in the heating channel 30c in a structure that is kept in non-contact with the heat-insulating member 30. Therefore, the heat generated by the heating element 20 can be prevented from being directly transferred to the heat insulation member 30 in a heat conduction mode, which is beneficial to reducing the heat transfer speed and the heat exchange efficiency between the heating element 20 and the heat insulation member 30.

In particular, a heat radiation preventing material layer (not shown) may be provided on the surface of the heat generating body 20 (for example, at least the surface facing the side wall of the heat insulation), and the heat radiation preventing material layer may be a film layer or coating layer with low emissivity such as aluminum, glass fiber, ceramic fiber, etc. coated on the surface of the heat generating body 20, so that the heat radiation of the heat generating body 20 to the heat insulating member 30, etc. can be effectively reduced.

In one embodiment, referring to fig. 2, 3 and 5, the outer housing 10 has two vent ports opposite to each other in the axial direction of the insulator 30; one of the ventilation ports may be provided in the lower housing part 12, mainly for external air to enter the outer housing 10, and be heated to form a hot air flow when flowing through the heating body 20; another ventilation port may be provided in the upper housing portion 11, and is mainly used for discharging aerosol mist generated or released by the medium to be atomized due to baking and heating out of the outer housing 10, or for providing a structural channel for inserting the medium to be atomized (such as the cigarette a shown in fig. 1) into the outer housing 10; for convenience of distinction and description, a vent port into which an external space is introduced is defined as an inlet passage 10a, and a vent port through which aerosol mist is discharged or into which a medium to be atomized is inserted is defined as an outlet passage 10b.

The inlet channel 10a and the outlet channel 10b each have a joint structure 10c, the joint structure 10c may be a sleeve structure disposed around the axial direction of the heat insulator 30, and the joint structure 10c extends into the heating channel 30b and is disposed in contact with the heat-insulating side wall of the heat insulator 30; it will also be appreciated that the two tubular body ports of the insulator 30 in the axial direction are nested over the engagement formations 10c at the respective ends. The heating element 20 is disposed between the air inlet channel 10a and the air outlet channel 10b, for example, the heating element 20 may be fixed on the joint structure 10c of the air inlet channel 10a, and ensure that the air inlet channel 10a and the air outlet channel 10b are kept in communication for air flow.

Therefore, the heat insulator 30 and the heating element 20 can be fixedly arranged in the outer shell 10 by the joint structure 10c, and part of heat absorbed by the outer shell 10 can be transferred to the heat insulator 30 and finally absorbed by the inner heat absorbing medium of the first chamber 30a by the contact relation between the joint structure 10c and the heat insulator 30, so that heat loss caused by heat leakage is further prevented.

In one embodiment, referring to fig. 2, 3 and 5, a limiting structure 10d is further disposed in the outer housing 10, and the limiting structure 10d is disposed around the corresponding ventilation port or the corresponding engagement structure 10 c; the two ends (specifically, the axial end wall 31) of the heat insulating side wall in the axial direction of the heat insulating member 30 are respectively abutted against the limiting structures 10d at the corresponding ends. On the one hand, by means of the cooperation of the limiting structure 10d and the joint structure 10c, the heat insulation member 30 can be stably fixed in the outer shell 10, and the heat insulation member 30 is prevented from axially moving; on the other hand, by the abutting contact between the axial end wall portion 31 and the limit structure 10d, the heat absorbing medium in the first chamber 30a can further absorb the heat of the outer casing 10, so as to reduce the temperature (for example, the surface temperature) of the outer casing 10 and enhance the heat-insulating effect.

In one embodiment, referring to fig. 2, 3 and 5, the heating element 20 includes a sleeve portion 21 and a base portion 22; wherein the sleeve portion 21 has two ports opposite to each other in the axial direction of the heat insulator 30, and the two ports of the sleeve portion 21 respectively extend into the engaging structures 10c of the corresponding ends; the base portion 22 is inserted into a port of the sleeve portion 21 near one end of the air inlet channel 10a, and the base portion 22 is provided with a plurality of ventilation channels which are arranged in a penetrating manner; the air inlet channel 10a, the tube body space of the sleeve part 21 and the air outlet channel 10b can be communicated by the ventilation duct; thus, an air flow channel for air flow in and out or circulation can be formed in the atomization device.

In particular, the sleeve portion 21 and/or the base portion 22 may be electrically connected to the control portion 13, so that the heating element 20 is heated by energizing it, so as to heat the air flow flowing therethrough or heat the medium to be atomized which extends into the sleeve portion 21 through the air outlet passage 10b.

In other embodiments, an electromagnetic coil or the like may be provided on the outer periphery of the heat generating body 20 to construct an electromagnetic heat generating structure based on the selection of the relative positional relationship between the heat generating body 20 and the heat insulating material 30 or the structural configuration.

The foregoing description of the utility model has been presented for purposes of illustration and description, and is not intended to be limiting. Several simple deductions, modifications or substitutions may also be made by a person skilled in the art to which the utility model pertains, based on the idea of the utility model.
