[0029] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application.
[0030] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0032] In the present application, the reference to "one embodiment", "some embodiments" or "embodiments" means that the specific features, structures or characteristics described in connection with the embodiment are included in one or more embodiments of the present application. Therefore, the statements "in one embodiment", "in some embodiments", "in other some embodiments", "in other some embodiments" and the like appearing in different places in the specification are not necessarily all referring to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized. In addition, in one or more embodiments, specific features, structures or characteristics can be combined in any suitable manner.
[0033] In order to illustrate the technical solutions of the present application, the following will be described in conjunction with specific drawings and examples.
[0034] With the rapid development of technology, various aerosol generating devices have appeared to meet different needs of users and improve the use experience, including heat-not-burn aerosol generating devices. The heat-not-burn aerosol generating device generally includes a heating body, which uses external heating or internal heating to heat the aerosol generating substrate to generate aerosol.
[0035] In the related art, when the heating body uses internal heating to heat the aerosol generating substrate, the heating body needs to be in contact with the aerosol generating substrate. During the heating process, the aerosol generating substrate is easy to stick to the heating body, and when the heating body is separated from the aerosol generating substrate, the aerosol generating substrate is prone to the problem of slag falling.
[0036] In view of this, the present application provides a heating assembly and an aerosol generating device. Since the heating assembly includes a heating body and a power piece, and the power piece is connected to the heating body, when the heating body is in contact with the aerosol generating substrate to heat the aerosol generating substrate, the power piece can drive the heating body to vibrate, thereby solving the problem that the aerosol generating substrate is easy to stick to the heating body during the heating process, and the aerosol generating substrate is prone to the problem of slag falling when the heating body is separated from the aerosol generating substrate.
[0037] Please refer to Figure 1 , Figure 1 is a structural schematic diagram of the heating assembly 100 in the first embodiment of the present application.
[0038] In a first aspect, the first embodiment of the present application provides a heating assembly 100 for an aerosol generating device. The heating assembly 100 includes a heating body 10 and a power piece 20. The heating body 10 is used to contact and heat an aerosol generating substrate (not shown in the figure). The power piece 20 is connected to the heating body 10, and the power piece 20 is used to drive the heating body 10 to vibrate.
[0039] The heating body 10 can be a heating needle or a heating tube, etc.
[0040] For example, when the heating body 10 is a heating needle, the heating body 10 can be inserted into the aerosol generating substrate, the heating body 10 is in contact with the aerosol generating substrate, and the power piece 20 can be wrapped around the outside of the heating body 10. When the heating body 10 is a heating tube, i.e., the shape of the heating body 10 is tubular, the aerosol generating substrate can be inserted into the inside of the heating body 10, the heating body 10 is in contact with the aerosol generating substrate, and the power piece 20 can be wrapped around the outside of the heating body 10. In other embodiments, the power piece 20 can also be installed inside the heating body 10.
[0041] The heating body 10 and the power element 20 can be in contact at 360 degrees or at a smaller angle, and can be in direct contact or indirect contact through a metal sheet or plastic.
[0042] The power element 20 can include a vibration motor, an ultrasonic transducer element, or other components that can drive the heating body 10 to vibrate. In the first embodiment, the power element 20 includes an ultrasonic transducer element.
[0043] As can be seen from the above, the heating assembly 100 provided by the application can drive the heating body 10 to vibrate through the power element 20 when the heating body 10 is in contact with the aerosol generating substrate to heat the aerosol generating substrate, thereby solving the problem that the aerosol generating substrate is easily bonded to the heating body 10 during the heating process and is prone to falling slag when the heating body 10 is separated from the aerosol generating substrate.
[0044] The conventional heating body 10 has a single function and usually relies on heat conduction and heat radiation to transfer heat, and the heating effect is limited by the law of heat transfer and is difficult to further improve. The heating assembly 100 provided by the application can drive the heating body 10 to vibrate through the power element 20, which can optimize the mass transfer and heat transfer effect during the baking process to a certain extent.
[0045] It should be noted that the power element 20 is a ring-shaped ultrasonic transducer element (single or multiple ultrasonic transducer pieces), and the power element 20 can also be a tubular ultrasonic transducer element (multiple pieces of stacked integrated ultrasonic transducer pieces). The ultrasonic transducer element can include a single-layer block element, a multi-layer co-fired element, or a multiple-piece element package integrated module. The shape, ultrasonic performance specifications, material, texture, grain orientation, electrode number, electrode process (coating or pasting metal foil), working method, and working time of the ultrasonic transducer element are not limited in this embodiment.
[0046] In the first embodiment, the power element 20 has a ring shape, and the power element 20 is sleeved on the heating body 10.
[0047] By adopting the above scheme, the power element 20 and the heating body 10 are conveniently connected.
[0048] In the first embodiment, the power element 20 is an ultrasonic transducer element, which has a small volume and is convenient to arrange. The positive and negative electrode leads of the ultrasonic transducer element can be led out from the opposite positions of the outer circumferential surface and the inner wall surface of the power element 20. The vibration direction of the heating body 10 can be parallel to the axis of the heating body 10, the axis of the heating body 10 is parallel to the direction indicated by the arrow M in the figure, and the heating body 10 vibrates vertically. The axis of the heating body 10 can be parallel to the axis of the aerosol generating substrate.
[0049] The power element 20 can be arranged at an end of the heat generating body 10 away from the aerosol generating substrate, and the heat generating body 10 can be arranged to connect the lead wire 11.
[0050] For example, the power element 20 and the heat generating body 10 can be connected by mechanical or non-mechanical means such as adhesion, welding, threaded connection, snap ring connection, or snap connection.
[0051] For example, the power element 20 and the heat generating body 10 are adhered by a glass ceramic adhesive, wherein the glass ceramic adhesive includes:
[0052] Glass ceramic adhesive formula 1: a mixture composed of titanium silicate glass powder, piezoelectric ceramic powder (lead zirconate titanate powder or potassium sodium niobate powder, i.e. transducer sheet ceramic composition), and oxide powder (not limited to aluminum oxide, tellurium oxide, cerium oxide powder, etc.);
[0053] Glass ceramic adhesive formula 2: zirconium silicate inorganic polymer, or aluminum silicate inorganic polymer, or a mixture of the two;
[0054] Glass ceramic adhesive formula 3: water glass (may be one or more layers of water glass adhesive layer with different modulus).
[0055] The above three formulas are filled into the joint between the surface of the heat generating body 10 and the power element 20 after being made into slurry, and can be repeatedly filled, sintered, refilled, and resintered to make the joint more full.
[0056] Glass ceramic adhesive formula 4: titanium silicate glass ring, which is melted and collapses to fill the joint between the surface of the heat generating body 10 and the power element 20, and can be used independently or after preliminary filling and sintering using the above glass ceramic adhesive formulas 1-3.
[0057] All of the above formulas can be arranged with a slope on the surface of the heat generating body 10 or a blocking feature (such as a flange) at the end of the joint to prevent the glass ceramic adhesive from falling out due to gravity.
[0058] For another example, the power element 20 and the heat generating body 10 are connected by a Kovar alloy transition layer and brazing, and the welding structure includes, in order, a metal shell of the heat generating body 10, an active brazing material layer, a Kovar alloy, an active brazing material layer, and the power element 20.
[0059] It should be noted that, in order to prevent the ultrasonic transducing element from leaking harmful elements, a skin can be arranged outside the ultrasonic transducing element to shield the harmful elements of the ultrasonic transducing element from entering the external environment. The skin can be selected from a metal skin or a metal frame (aluminum or stainless steel material, etc., which can be achieved by assembly, welding or other mechanical methods, and attention should be paid to insulation), or a plastic skin (polyether ether ketone or silicone, etc., which can be achieved by assembly or in-mold injection).
[0060] In order to make the structure of the heating assembly 100 more compact and occupy less space, the outer wall of the heating body 10 is electrically conductive, the inner wall of the power piece 20 is provided with an electrode lead (not shown in the figure), and the outer wall of the heating body 10 is connected with the electrode lead and electrically conductive.
[0061] By adopting the above scheme, the outer wall of the heating body 10 can be used as the lead wire of the power piece 20, so that the structure of the heating assembly 100 is more compact and occupies less space.
[0062] The outer wall of the heating body 10 is provided with a conductive coating (not shown in the figure), and the electrode lead is connected with the conductive coating and electrically conductive.
[0063] In this way, the electrical contact performance between the outer wall of the heating body 10 and the electrode lead can be better.
[0064] For example, the conductive coating includes a silver layer, a copper layer or a graphite layer.
[0065] In this way, the conductive coating is convenient to set.
[0066] Please refer to Figure 2 , Figure 2 is a structural schematic view of the heating assembly 100 in the second embodiment of the present application.
[0067] Different from the first embodiment, in the second embodiment, the thickness of the power piece 20 in the direction along the axis of the power piece 20 is smaller, and the electrode lead of the power piece 20 can be led out from the two end faces of the power piece 20.
[0068] By adopting the above scheme, when the heating body 10 is in contact with the aerosol generating substrate to heat the aerosol generating substrate, the heating body 10 can be vibrated by the power piece 20, so that the problem that the aerosol generating substrate is easily bonded on the heating body 10 in the heating process and the aerosol generating substrate is prone to slagging when the heating body 10 is separated from the aerosol generating substrate can be solved, and the electrode lead of the power piece 20 is convenient to lead out.
[0069] Please refer to Figure 3 , Figure 3 is a structural schematic view of the heating assembly 100 in the third embodiment of the present application.
[0070] Different from the first embodiment, in the third embodiment, the heating assembly 100 comprises an injection molding piece 30, which is arranged between the outer wall of the heating body 10 and the inner wall of the power piece 20 and respectively connects the outer wall of the heating body 10 and the inner wall of the power piece 20.
[0071] By adopting the above scheme, when the heating body 10 is in contact with the aerosol generating substrate to heat the aerosol generating substrate, the heating body 10 can be driven to vibrate by the power piece 20, so that the problem that the aerosol generating substrate is easy to stick to the heating body 10 during the heating process and the problem that the aerosol generating substrate is easy to drop slag when the heating body 10 is separated from the aerosol generating substrate can be solved, and the heating body 10 and the power piece 20 are not directly in contact, but connected into a whole through the injection molding piece 30.
[0072] It should be noted that the injection molding piece 30 can comprise in-mold injection PEEK (polyether-ether-ketone) or other plastics. The power piece 20 and the outer wall of the heating body 10 leave a gap space, which is pre-placed in the mold, and the in-mold injection PEEK fills the gap space and wholly or partially covers the power piece 20 to protect the power piece 20.
[0073] Please refer to Figure 4 and Figure 5 , Figure 4 is a structure schematic diagram of a heating assembly 100 in a fourth embodiment of the present application, Figure 5 is a structure exploded view of the heating assembly 100 in the fourth embodiment of the present application.
[0074] Different from the first embodiment, in the fourth embodiment, a containing space 101 is arranged in the heating body 10, and the power piece 20 is arranged in the containing space 101.
[0075] By adopting the above scheme, when the heating body 10 is in contact with the aerosol generating substrate to heat the aerosol generating substrate, the heating body 10 can be driven to vibrate by the power piece 20, so that the problem that the aerosol generating substrate is easy to stick to the heating body 10 during the heating process and the problem that the aerosol generating substrate is easy to drop slag when the heating body 10 is separated from the aerosol generating substrate can be solved, and the power piece 20 can be protected to avoid damage caused by contacting other objects.
[0076] Please refer to Figure 6 , Figure 6 is a structure schematic diagram of a heating assembly 100 in a fifth embodiment of the present application.
[0077] Different from the first embodiment, in the fifth embodiment, the vibration direction of the heating body 10 is perpendicular to the axis of the heating body 10.
[0078] By adopting the above scheme, when the heating body 10 is in contact with the aerosol generating substrate to heat the aerosol generating substrate, the power element 20 can drive the heating body 10 to vibrate, so that the problem that the aerosol generating substrate is easy to stick to the heating body 10 during heating and the problem that the aerosol generating substrate is easy to drop slag when the heating body 10 is separated from the aerosol generating substrate can be solved.
[0079] It can be understood that the ultrasonic transducer element can be replaced by a thin sheet structure to change the ultrasonic vibration direction, so as to change the vibration direction of the heating body 10, so that the heating body 10 vibrates horizontally. The electrode lead of the ultrasonic transducer element can be led out from two largest cross sections of the power element 20.
