Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic cigarette technology, and in particular to a heating component and an aerosol generating device. Background Technology
[0002] Existing aerosol atomizing devices generally have a smoke extractor. The aerosol generating product can be inserted into the smoke extractor, and the aerosol generating matrix inside the aerosol generating product is heated by a heating element to generate aerosol, thereby meeting the user's inhalation needs.
[0003] Some existing aerosol generating devices use a dual-heating-needle structure for their heating element. When the aerosol generating product is inserted around the dual-heating-needle, the heating element is arranged in parallel. In the direction of the line connecting the two needles, the heating element is close to the packaging material of the aerosol generating product. The packaging material is prone to contact heating and scorching or heat transfer scorching, which affects the user's inhalation taste and experience. Utility Model Content
[0004] The purpose of this invention is to provide a heating component and an aerosol generating device to solve the problem that the packaging material is easily scorched or burned due to heat transfer caused by the close proximity of the dual-heating needle heating element to the packaging material, thereby improving the user's inhalation taste and experience.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] Heating components, including:
[0007] A heating element, the heating element comprising two heating needles spaced apart, the two heating needles being arranged along a first direction;
[0008] A smoke extractor has a receiving cavity for inserting an aerosol-generating product. A heating needle is placed in the receiving cavity from one end of the smoke extractor. The smoke extractor also includes a squeezing wall. When the aerosol-generating product is inserted into the receiving cavity, the squeezing wall can squeeze the aerosol-generating product in a second direction, so that a portion of the structure of the aerosol-generating product undergoes expansion deformation in the first direction.
[0009] As an alternative heating component, the smoke extractor includes two opposing extrusion walls.
[0010] As an alternative heating component, the distance between the two extrusion walls gradually decreases along the insertion direction of the aerosol-generated article, which is not parallel to either the first or the second direction.
[0011] As an alternative heating component, the first direction and the second direction are not parallel.
[0012] As an alternative heating component, the smoke extractor has notches on both sides along the first direction, and a portion of the structure of the aerosol-generated product can enter the notches after expanding and deforming in the first direction.
[0013] As an alternative heating component, the surface of the extrusion wall opposite to the aerosol-generated article is planar.
[0014] As an alternative heating component, the extrusion wall relative to the surface of the aerosol-generated article is a combination of planar and curved surfaces.
[0015] As an alternative heating component, the transition between the curved surface and the flat surface is smooth.
[0016] As an alternative heating component, the smoke extractor includes a cylindrical inlet connected to the extrusion wall, the inlet serving to guide the aerosol-generated article into the extrusion wall.
[0017] The aerosol generating device includes the heating component described in any of the above embodiments.
[0018] Beneficial effects:
[0019] In the first aspect of this invention, the extrusion action of the extrusion wall of the heating component causes the aerosol-generating product to shrink in the second direction and expand in the first direction. This further adjusts the packaging material of the aerosol-generating product from a circular cross-section to an irregular shape with a relatively elongated width in the first direction and a narrowed width in the second direction. As a result, the packaging material of the aerosol-generating product is farther away from the surface of the heating needles in the first direction, i.e., the line connecting the two heating needles. This effectively avoids the packaging material from easily contacting the heating needles and burning due to heat or heat transfer issues caused by close proximity, thus effectively improving the user's inhalation taste and experience.
[0020] In a second aspect of this invention, the aerosol generating device based on this heating component effectively avoids the problem of scorching of the packaging material of the aerosol-generated product, thereby ensuring the user's inhalation experience. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0033] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0034] Please see the appendix Figure 1 -Appendix Figure 4 The first aspect of this embodiment relates to a heating assembly, which includes a heating element 1 and a smoke lifter 2. Specifically, the heating element 1 includes two heating needles 11 spaced apart and arranged along a first direction X; the smoke lifter 2 has a receiving cavity 21 for inserting an aerosol generating article 100, and the heating needles 11 are placed in the receiving cavity 21 from one end of the smoke lifter 2. The smoke lifter 2 also includes a compression wall 22, which can compress the aerosol generating article 100 in a second direction Y when the aerosol generating article 100 is inserted into the receiving cavity 21, so that a portion of the structure of the aerosol generating article 100 undergoes expansion deformation in the first direction X.
[0035] In this embodiment, the top of the heating needle 11 has a certain taper for easy insertion into the aerosol generating article 100. Two heating needles 11 are arranged at intervals along the first direction X inside the receiving cavity 21. The aerosol generating article 100 is inserted into the receiving cavity 21 of the cigarette holder 2. The contents of the aerosol generating article 100 (such as tobacco) can contact the two heating needles 11 and generate aerosol for the user to inhale through the heating effect of the heating needles 11.
[0036] Furthermore, the extrusion walls 22 are spaced apart in the second direction Y. The extrusion walls 22 can clamp and extrude the aerosol generating article 100 in the second direction Y, so that the aerosol generating article 100 is subjected to pressure and contracts in the second direction Y. At the same time, part of the structure of the aerosol generating article 100 can undergo a certain expansion deformation outward in the first direction X. Through the extrusion action of the extrusion walls 22, this application causes the aerosol generating article 100 to contract in the second direction Y and expand in the first direction X, further adjusting the cross-section of the packaging material of the aerosol generating article 100 to an irregular shape in which the width in the first direction X is relatively elongated and the width in the second direction Y is narrowed. Thus, the packaging material of the aerosol generating article 100 is farther away from the surface of the heating needles 11 in the first direction X, that is, the line connecting the two heating needles 11. This effectively avoids the packaging material from easily contacting the heating needles 11 and causing scorching due to heat, or the two being too close and causing heat transfer scorching, effectively improving the user's inhalation taste and experience.
[0037] Optionally, the main body of the heating needle 11 can be a cylindrical structure, a sheet-like structure, or an irregular structure distributed along the first direction X.
[0038] Optionally, aerosol generating article 100 refers to an article comprising an aerosol generating matrix intended to be heated rather than burned to release volatile compounds that can form aerosols. When heated, the aerosol generating matrix releases volatile compounds that can form aerosols. Aerosols formed by heating the aerosol generating matrix may contain fewer known hazardous components than aerosols generated by combustion or pyrolytic degradation of the aerosol generating matrix. Aerosol generating article 100 may be disposable or reusable. The aerosol generating matrix may be a solid aerosol generating matrix. Alternatively, the aerosol generating matrix may include solid and liquid components. The aerosol generating matrix may include tobacco and / or non-tobacco materials; or the aerosol generating matrix may include tobacco-containing materials and / or non-tobacco materials; wherein the tobacco-containing materials contain volatile tobacco flavor compounds that are released from the matrix upon heating.
[0039] Optionally, the aerosol generating product 100 can be a cigarette with a cylindrical structure including tobacco shreds, and the packaging material can be cigarette paper wrapping the tobacco shreds. Through the squeezing action of the two extrusion walls 22, the aerosol generating product 100 contracts in the second direction Y and expands in the first direction X, further adjusting the packaging material of the aerosol generating product 100 from a circular cross-section to an elliptical cross-section with a relatively elongated width in the first direction X and a narrowed width in the second direction Y. Thus, the packaging material of the aerosol generating product 100 is farther from the surface of the heating needles 11 in the first direction X, i.e., the line connecting the two heating needles 11, effectively avoiding the packaging material easily contacting the heating needles 11 and causing scorching due to heat, or the two being too close and causing heat transfer scorching. Optionally, the cigarette holder 2 can include two opposing extrusion walls 22, which can better clamp and squeeze the aerosol generating product 100 in the second direction Y, causing the aerosol generating product 100 to be under pressure and contract in the second direction Y.
[0040] Optionally, the distance between the two extrusion walls 22 gradually decreases along the insertion direction of the aerosol-generated article 100, and the insertion direction is not parallel to either the first direction X or the second direction Y.
[0041] The insertion direction of the aerosol generating article 100 can be a direction perpendicular to the first direction X and / or the second direction Y. For example, the first direction X and the second direction Y can be mutually perpendicular directions within the cross section of the length direction of the smoke lifter 2, and the insertion direction of the aerosol generating article 100 can be a direction parallel to the length direction of the smoke lifter 2.
[0042] Of course, in other embodiments, by gradually reducing the distance between the two extrusion walls 22, it is possible to take into account the gradual increase of extrusion pressure while ensuring the effectiveness of the extrusion effect.
[0043] Optionally, the first direction X and the second direction Y are not parallel, which facilitates the extrusion wall 22 to clamp and extrude the aerosol generating article 100 in the second direction Y, so that the aerosol generating article 100 is under pressure and contracts in the second direction Y, thereby allowing the aerosol generating article 100 to deform and extend in the first direction X, and the packaging material of the aerosol generating article 100 to be further away from the surface of the heating needle 11 in the first direction X.
[0044] In this embodiment, the first direction X and the second direction Y maintain a certain angle. For example, the degree range of the angle can be 80° to 90°.
[0045] Preferably, the first direction X and the second direction Y are perpendicular to each other, which can ensure that the expansion and extension direction of the aerosol generating product 100 is consistent with the first direction X, thereby better increasing the distance between the aerosol generating product 100 and the heating needle 11.
[0046] Furthermore, the first direction X and the second direction Y are perpendicular to each other in the cross section along the length of the smoke generator 2, thereby maximizing the distance between the aerosol generating product 100 and the heating needle 11.
[0047] Optionally, the smoke extractor 2 has notches 23 on both sides along the first direction X, and a portion of the structure of the aerosol generating product 100 can enter the notches 23 after expanding and deforming in the first direction X.
[0048] Specifically, the shape of the notch 23 needs to be adapted to the part of the aerosol generating article 100 that undergoes expansion and deformation, and the size of the notch 23 is slightly larger than the size of the part of the aerosol generating article 100 that undergoes deformation.
[0049] In this embodiment, the notch 23 can be used to avoid part of the structure of the deformed aerosol-generated article 100, so as to ensure that the aerosol-generated article 100 can extend and expand on its own.
[0050] Optionally, the surface of the extrusion wall 22 opposite to the aerosol-generating article 100 is planar.
[0051] Specifically, the surfaces of the two extrusion walls 22 opposite each other can be planes, and the distance between the two planes is less than the diameter of the aerosol-generated article 100 to ensure effective extrusion of the aerosol-generated article 100 in the second direction Y.
[0052] Optionally, the surface of the extrusion wall 22 relative to the surface of the aerosol-generated article 100 is a combination of planar and curved surfaces.
[0053] In this embodiment, the extrusion wall 22 can be a combination of curved and flat surfaces. Specifically, the initial contact extrusion part of the extrusion wall 22 is a curved surface, and the shape of the curved surface gradually transitions from a cylindrical surface that adapts to the aerosol generating product 100 to a flat surface, so that the extrusion wall 22 extrudes the aerosol generating product 100 in a process of gradually applying pressure.
[0054] Furthermore, the transition between curved surfaces and planes is smooth.
[0055] In addition, the connection between the curved surface and the flat surface needs to be smooth to ensure that the aerosol generating product 100 remains smooth and stable after being continuously inserted into the smoke extractor 2 to the bottom, thereby avoiding the sharp edges from scratching the aerosol generating product 100 at the connection and causing damage to the aerosol generating product 100.
[0056] Optionally, the smoke extractor 2 includes a cylindrical inlet 24 connected to the extrusion wall 22. The inlet 24 guides the aerosol-generating article 100 to be inserted into the extrusion wall 22. For example, when the smoke extractor 2 is provided with two extrusion walls 22, the aerosol-generating article 100 can be inserted between the two extrusion walls 22 under the guidance of the inlet 24.
[0057] In this embodiment, the inlet portion 24 still has a cylindrical structure adapted to the shape of the aerosol-generating article 100. The inlet portion 24 is provided with an inlet hole, allowing the user to directly insert the aerosol-generating article 100 into the inlet hole in the correct direction, and further into the space between the two extrusion walls 22. The inlet portion 24 provides guidance for the insertion of the aerosol-generating article 100, thereby effectively ensuring that the aerosol-generating article 100 maintains the correct posture before being inserted into the two extrusion walls 22.
[0058] The second aspect of this embodiment also relates to an aerosol generating apparatus, which includes the heating component, battery, and control element described above. The battery provides electrical energy to the heating component and the control element. The heating component is electrically connected to the control element and can be activated under the control of the control element. Thus, the heating component can heat the aerosol generating article 100 inserted therein to generate aerosol for the user to inhale.
[0059] The aerosol generating device based on this heating component can effectively prevent the packaging material of the aerosol-generated product 100 from scorching, thereby effectively ensuring the user's inhalation experience. The aerosol generating device can be used for low-temperature heated smoking devices.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
