DETAILED DESCRIPTION

[0033] In order to have a clearer understanding of the technical features, objectives and effects of the present application, the specific embodiments of the present application will be described in detail with reference to the drawings.

[0034] Referring to Figure 1 and Figure 2 Some embodiments of the present application provide a heating-not-burning electronic atomization device 1, which is a segmented heating device with a movable temperature field, i.e. a heating device 12, and can perform small-area segmented heating by moving the moving field, generating a long-lasting and odorless aerosol.

[0035] Referring to Figure 3The heating device 12 is used to heat and bake the solid aerosol generating matrix 22, which is detachably inserted into the heating device 12, to release the heated aerosol extract of the solid aerosol generating matrix 22 in a non-combustible state. As shown in Figure 1, the solid aerosol generating matrix 22 can be cylindrical. Correspondingly, the top of the heating non-combustible baking device 1 is provided with an insertion hole 111 of a size adapted to the solid aerosol generating matrix 22. An insertion hole cover 112 can be provided next to the insertion hole 111 to cover or fasten to the insertion hole 111, thereby preventing foreign objects from entering the insertion hole 111 and hindering the use of the heating non-combustible baking device 1.

[0036] See also Figure 3 In some embodiments, the heated non-combustible electronic atomizing device 1 may include a longitudinally elongated housing 11 and a heating device 12, a power supply 13, and a main control board 14 disposed within the housing 11. The heating device 12 and the main control board 14 are electrically connected to the power supply 13. The main control board 14 is used to house the circuit components required for the heated non-combustible electronic atomizing device 1 and to control related circuitry. In some embodiments, the heating device 12 may be cylindrical, allowing the solid aerosol generating matrix 22 to be inserted within the heating device 12 for heating and baking.

[0037] The following describes in detail the connection relationships, positional relationships, and necessary motion relationships within the heating device 12, such as... Figure 4 As shown, in some embodiments, the heating device 12 may include a drive device 121, a heating assembly 122, and a support 123. The heating assembly 122 may include a component 1222 movably mounted on the support 123, which enables the heating device 12 to have or form a variable temperature field, thereby allowing the solid aerosol generating matrix 22 inserted therein to be uniformly heated. The drive device 121 is connected to this component and is used to move the component on the support 123 to achieve a variable temperature field. In some embodiments, the support 123 may be a hollow cylindrical support, used to support or hold the drive device 121 and the heating assembly 122.

[0038] In one specific embodiment, the heating device 12 is a heating device that achieves heating through the principle of electromagnetic induction, i.e., the heating device 12 is an electromagnetic heating device, at which time the component 1222 can be an electromagnetic coil that is movably or telescopically installed on the support 123, and the heating assembly 122 can further include a magnetosensitive element 1221 that cooperates with the electromagnetic coil. The magnetosensitive element 1221 can be in the form of a cylinder in some embodiments, and the electromagnetic coil can generate or release heat under the action of an alternating magnetic field to heat and atomize the solid aerosol generating substrate 22 inserted therein. Since the electromagnetic coil is movable and / or telescopic relative to the support 123 in the longitudinal direction, the electromagnetic coil generates heat under the action of an electromagnetic induction system (described in detail below). Understandably, the heating device 12 is not limited to an electromagnetic heating device, and can be a resistive heating device in other embodiments, at which time the component 1222 can be a resistive heating element.

[0039] In some embodiments, the electromagnetic coil type component 1222 is directly or indirectly sleeved on the support 123, and the magnetosensitive element 1221 is inserted or clamped in the support 123, and the electromagnetic induction system formed by the combination of the electromagnetic coil and the magnetosensitive element 1221 is connected to the power supply 13 in a constant voltage or constant power or constant pulse manner, and by controlling the change of the voltage, the electromagnetic coil (conductor) has current passing therethrough, so that a high-frequency alternating magnetic field is generated in the electromagnetic coil, and the magnetic force of the high-frequency alternating magnetic field first passes through the electromagnetic coil to generate a large amount of annular eddy current, and the eddy current heat effect releases a large amount of heat to make the electromagnetic coil heat at a high speed, thereby achieving the purpose of heating the solid aerosol generating substrate 2 through the electromagnetic coil. Understandably, the magnetosensitive element 1221 can be a stepped or straight cylinder magnetosensitive element to further improve the efficiency of heating the solid aerosol generating substrate 22. Understandably, the magnetosensitive element 1221 can also be arranged inside the solid aerosol generating substrate 22 in some embodiments.

[0040] Referring to Figure 5aThe driving device 121 can be integrally formed or segmented in some embodiments. Preferably, the driving device 121 is a segmented driving device, which includes a first driving element 1211 and a second driving element 1212, and the first driving element 1211 and the second driving element 1212 are arranged on the upper portion and the lower portion of the support 123, respectively. The height of the upper portion and the lower portion can be equal or not equal. Preferably, the height of the upper portion and the lower portion is equal, and correspondingly, the height of the first driving element 1211 and the second driving element 1212 is equal, for the convenience of processing and manufacturing. The first driving element 1211 and the second driving element 1212 are directly or indirectly connected, and specifically, the first driving element 1211 and the second driving element 1212 can be connected by clamping, hanging, screwing or the like, and in this case, the driving device 121 is located or placed between the electromagnetic coil and the support 123; or the first driving element 1211 and the second driving element 1212 are connected by the electromagnetic coil, and in this case, the driving device 121 is located or placed on the surface of the support 123.

[0041] Specifically, the number of the first driving element 1211 and the second driving element 1212 is one or more, and preferably, the number of the first driving element 1211 and the second driving element 1212 is one, for the convenience of installation and use. Both the first driving element 1211 and the second driving element 1212 are made of shape memory alloy material, or one of them is made of shape memory alloy material and the other is made of ordinary alloy material. In the present embodiment, the first driving element 1211 and the second driving element 1212 can be shape memory alloy springs or shape memory alloy wires with adjustable length, and the driving stroke of the spring or the shape memory alloy wire after being electrified is 1%-400% of the initial length or the original length, and preferably, the driving stroke of the spring is 50%-100% of the initial length. Under the condition that the electromagnetic coil and the magnetic sensing element 1221 work together, according to the foregoing principle, in the heating process, the first driving element 1211 and the electromagnetic coil are elongated, and at the same time, the electromagnetic coil is also moved up and down, and the second driving element 1212 is contracted. In some embodiments, the driving device 121 can have a sleeve structure with a certain thickness, and is sleeved on the upper portion and the lower portion of the support 123, respectively.

[0042] In some embodiments, the first driving element 1211 adopts a shape memory alloy material, the second driving element 1212 adopts a common alloy material; or the first driving element 1211 adopts a common alloy material, the second driving element 1212 adopts a shape memory alloy material; or the first driving element 1211 and the second driving element 1212 both adopt a shape memory alloy material, and the first driving element 1211 and the second driving element 1212 are in different stages of shape memory effect, specifically, the first driving element 1211 is in a heating stage, and the second driving element 1212 is in an end-of-heating stage.

[0043] Referring to Figure 5a , Figure 5b and Figure 5c , the length change trend of the first driving element 1211, the second driving element 1212 and the electromagnetic coil is described below with quantifiable data: assuming that the lengths or heights of the first driving element 1211 and the second driving element 1212 are L1 and L2 respectively, and the length of the electromagnetic coil is H1 in the initial or original state; in the early stage of the heating process, the lengths of the first driving element 1211 and the second driving element 1212 are L1-1 and L2-1 respectively, and the length of the electromagnetic coil is H1+1; in the late stage of the heating process, the lengths of the first driving element 1211 and the second driving element 1212 are L1-2 and L2-2 respectively, and the length of the electromagnetic coil is H1+2; at the end of the heating process, the lengths of the first driving element 1211 and the second driving element 1212 are L1 and L2 respectively, and the length of the electromagnetic coil is H1.

[0044] Wherein, L1

[0045] The connection relationship between the first driving element 1211, the second driving element 1212 and the bracket 123 is described in detail below, the proximal ends of the first driving element 1121 and the second driving element 1212 are connected, and the distal ends of the first driving element 1121 and the second driving element 1212 are connected to the corresponding end portions of the bracket 123 respectively.

[0046] In another specific embodiment, referring to Figure 6 , the difference from the first embodiment is that the heating device 12 comprises a magnetosensitive element 1221 (which has a heating function) and a component 1222.

[0047] In another embodiment (not shown), the heating body is heated by passing current through the heating body, and the heating assembly 122 in the heating device 12 only includes the component 1222, which can be a heating body such as a resistance block, and achieves the purpose of heating the solid aerosol generating substrate 22 based on the principle of the aforementioned shape memory alloy effect.

[0048] The heating assembly 122 in another embodiment (not shown) of the present application is mainly different from the above-mentioned heating assembly 122 in that the magnetic sensing element 1221 is in the form of a pin and is erected on the bottom of the inner cavity of the support 123 and is fixed with the support 123. When the solid aerosol generating substrate 22 is inserted into the heating device 12, the pin-shaped magnetic sensing element 1221 can be inserted into the pin-shaped magnetic sensing element 1221, and the magnetic sensing element 1221 has a heating function, which can further heat and bake the solid aerosol generating substrate 22.

[0049] In summary, the heating assembly in some embodiments of the present application is provided with a first driving element, a second driving element, a magnetic sensing element, and an electromagnetic coil, wherein the driving device is directly or indirectly connected with the electromagnetic coil, and the magnetic sensing element is combined with the electromagnetic coil to form an electromagnetic induction system. After the driving device (conductor) is powered on, a high-frequency alternating magnetic field is generated in the induction coil, and a large number of annular eddy currents are generated when the magnetic lines of the high-frequency alternating magnetic field pass through the electromagnetic coil. The eddy current heat effect releases a large amount of heat to make the electromagnetic coil heat at a high speed, so as to heat the new solid aerosol generating substrate 2 through the electromagnetic coil.

[0050] As mentioned above, the driving device in some embodiments of the present application can be made of shape memory alloy, which can elongate or contract after being powered on due to the resistance heating of the driving device itself, so as to drive the electromagnetic coil to move up and down. The driving device can deform under the condition of heat or heating, and after being heated to a certain temperature, the alloy returns to the original before deformation, which can drive the electromagnetic coil to move up and down or move to a fixed position and continue for a period of time, so as to realize the characteristic control of the temperature field.

[0051] It can be understood that the above technical features can be used in any combination without limitation.

[0052] The above description is only the embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation based on the content of the specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection scope of the present application.
