Description

Technical Field

[0001] This utility model belongs to the field of novel tobacco products, and specifically relates to an aerosol generating device. Background Technology

[0002] With increasing public awareness of health concerns, people have become increasingly aware of the health hazards of traditional cigarettes. This has led to the development of products called "heated cigarettes." Compared to traditional cigarettes, heated cigarettes release aerosols by heating the smoke-generating section of the aerosol-generating matrix. Because there is no combustion process, no complex chemical reactions occur. Therefore, heated cigarettes satisfy the user's physiological needs while reducing the amount of harmful substances such as tar and carbon monoxide found in traditional cigarettes, thus reducing the user's inhalation of harmful substances. As a result, heated cigarettes are increasingly favored by consumers.

[0003] Heated cigarettes are used by heating a specially designed cigarette stick with a heating device to produce an aerosol similar to that produced by cigarette combustion, which is then inhaled by the consumer. The aerosol generating device typically has an inner shell and an outer shell. The inner shell is the main body of the aerosol generating device, while the outer shell does not include the top cover of the main body. Both the inner and outer shells contain magnetic elements. The outer shell and inner shell are connected by magnetic attraction. The magnetic element is usually fixed at the top of the inner shell. If it is fixed with adhesive, the magnetic element may detach from the inner shell after repeated heating. Therefore, a better method is to use a bracket inside the inner shell to provide stable support for the magnetic element, thus fixing it to the top of the inner shell. To secure this bracket, the length of the fixing base (used to fix the heating element) is usually extended. The fixing base supports the bracket, thereby supporting the magnetic element. On the other hand, extending the radial dimension of the fixing base further allows the fixing support to abut against the inner shell of the aerosol generating device in the radial direction, thereby enabling the fixing base to be more securely fixed within the aerosol generating device. Simultaneously, other components connected to the fixing base can also be more securely fixed within the main body of the aerosol generating device.

[0004] However, the aforementioned aerosol generating device suffers from low heat utilization and significant heat loss. Utility Model Content

[0057] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Although the description of this utility model will be presented in conjunction with preferred embodiments, this does not mean that the features of this utility model are limited to this embodiment. On the contrary, the purpose of describing the utility model in conjunction with the embodiments is to cover other options or modifications that may be derived based on the claims of this utility model. To provide a deep understanding of this utility model, many specific details will be included in the following description. This utility model may also be implemented without using these details. Furthermore, to avoid confusion or obscuring the focus of this utility model, some specific details will be omitted in the description. It should be noted that, without conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0058] It should be noted that in this specification, similar reference numerals and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0059] The term "aerosol-generating article" is used herein to refer to an article in which an aerosol-generating matrix is ​​heated to produce an inhalable aerosol and delivered to a consumer, wherein "aerosol-generating matrix" refers to a matrix capable of releasing volatile compounds to generate an aerosol upon heating. For example, it could be a heated cigarette made by wrapping an aerosol-generating matrix, such as tobacco, in paper. An "aerosol-generating article" comprises an aerosol-generating matrix and a filter, and is used in conjunction with an aerosol-generating device for heating or by employing other heat-non-combustible methods to generate an aerosol for inhalation.

[0060] The terms “first”, “second”, etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0061] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0062] For the aerosol generating device of this invention, the radial length of the fixed base is fixed, thereby achieving a stable connection between the fixed base and other components within the aerosol generating device. Therefore, it is not desirable to shorten the radial dimension of the fixed base to avoid contact between the fixed base and the support. To address this, this invention proposes setting a gap between the support and the fixed base to prevent the support from indirectly absorbing heat from the heating element.

[0063] like Figure 1-4As shown, the aerosol generating device 1 provided by this utility model includes a fixed base 2, a heating element 3, and a support 4. The heating element 3 is mounted on the fixed base 2, wherein the fixed base 2 extends in the radial direction (X direction in the figure), and the support 4 extends in the axial direction (Z direction in the figure). The support 4 is located above the fixed base 2 and forms a first thermal insulation distance d1 with the fixed base 2 in the axial direction. By setting the first thermal insulation distance d1 between the fixed base 2 and the support 4, direct contact between the fixed base 2 and the support 4 is avoided, thereby preventing the support 4 from absorbing heat transferred from the heating element 3 to the fixed base 2. This achieves the technical effect of preventing heat from the heating element 3 from being indirectly transferred to the support 4, thus improving heat utilization efficiency and reducing energy loss.

[0064] Existing technologies typically reduce heat loss by minimizing the number of components in direct contact with the heating element. However, the mounting base used to hold the heating element itself generates significant heat. For example, when the heating element generates temperatures exceeding 300°C, the mounting base will experience heat transfer, rising to 90°C or even higher. Components in contact with the mounting base will then absorb heat from it, leading to further heat transfer from the heating element to the base, resulting in continued heat loss. Furthermore, because the bracket is connected to the mounting base and is a relatively large component, it absorbs a significant amount of heat from the base, further contributing to heat loss from the heating element. Additionally, the bracket, located on the side of the aerosol generator and extending axially, generates high temperatures due to heat absorption, potentially causing overheating of the aerosol generator's sidewalls and posing a risk of burns to the user. Therefore, this invention addresses these issues by creating a gap between the bracket and the mounting base.

[0065] Specifically, the fixed base 2 can be made of high-temperature resistant materials, such as PEEK, polyimide, ceramics, etc.; the bracket 4 is usually made of materials such as PC, nylon, etc., or it can be made of more economical materials such as ABS, PP, AS, etc.; the heating component 3 can be a heating needle or a heating rod.

[0066] To achieve the aforementioned thermal insulation gap, one might consider using adhesive or snap-fitting the bracket to the outer shell of the aerosol generator to fix the bracket inside the aerosol generator's housing, thus creating a thermal insulation gap with the mounting base. However, for products like aerosol generators that undergo repeated use, they are frequently exposed to repeated heating and extreme high and low temperature environments. In such cases, if adhesive is used to fix the bracket inside the aerosol generator to create a thermal insulation gap, the adhesive is prone to failure, leading to instability and the risk of the bracket falling off. Using a snap-fitting method to fix the bracket inside the aerosol generator to create a thermal insulation gap is also problematic. Since the bracket is typically made of plastic materials such as PC or nylon, repeated heating and shaking of the device can cause deformation at the snap-fitting point between the bracket and the outer shell of the aerosol generator due to thermal expansion and contraction, resulting in loosening. This snap-fitting method cannot guarantee a consistently stable thermal insulation gap between the bracket and the mounting base. Furthermore, this method is not suitable for aerosol generators. For small products like aerosol generating devices, the operating space is limited. Therefore, setting up a snap-fit ​​structure is extremely difficult. In addition, this operation requires high precision in the processing and installation of the snap-fit ​​structure and the bracket. Errors may occur during the production and installation process. Once an error occurs, there is a risk that the bracket may not be able to be stably fixed inside the aerosol generating device.

[0067] Combined Figures 10-11 To address the aforementioned problems, this invention employs a first magnetic body 5 on the fixed base 2 and a second magnetic body 6 on the support 4, wherein the first magnetic body 5 and the second magnetic body 6 have the same magnetic poles, forming a first thermal insulation gap d1 through repulsion. This method of forming the first thermal insulation gap d1 with magnetic bodies eliminates the risk of failure due to repeated heating processes, as the repulsive force remains constant. Furthermore, this method simplifies installation and reduces production costs by eliminating the need for high installation and manufacturing precision, making it particularly suitable for aerosol generating devices. Moreover, the constant repulsive force between the first magnetic body 5 and the second magnetic body 6 ensures a continuous repulsive force between the support 4 and the fixed base 2, thereby reducing heat loss from the heating component 3 while providing stable support for the support 4 without direct contact between the fixed base 2 and the support 4.

[0068] like Figure 2-Figure 3As shown, the aerosol generating device 1 of this utility model includes a first housing 7 and a second housing 9. The first housing 7 is an inner housing, and the second housing 9 is an outer housing. The inner housing is the main body of the aerosol generating device, and the outer housing does not include the upper cover of the main body of the aerosol generating device. The fixed base 2, the heating component 3, and the bracket 4 are located inside the first housing 7. A third magnetic body 8 is provided inside the first housing 7, and a fourth magnetic body 10 is provided in the second housing 9. The second housing 9 is sleeved on the first housing 7, that is, the first housing 7 is embedded in the second housing 9. Specifically, the first housing 7 and the second housing 9 are sleeved by the attraction between the third magnetic body 8 and the fourth magnetic body 10.

[0069] like Figure 2 and Figure 4 As shown, the present invention has a chamber 11 inside the first housing 7, wherein the support 4 is located inside the first housing 7. A limiting surface 12 is provided inside the chamber 11, which is used to restrict the movement of the support 4 in the axial direction. Specifically, the limiting surface 12 abuts against the support 4 in the axial direction (Z direction in the figure), and the abutment can restrict the support 4 from moving upward in the axial direction. Since there is a repulsive force between the first magnetic body 5 installed on the fixed base 2 and the second magnetic body 6 installed on the support 4, the support 4 will be driven to move upward in the axial direction. By setting the limiting surface 12 and abutting against the support 4, the support 4 is subjected to an upward force in the axial direction due to the repulsive force. The limiting surface 12 will then give the support 4 a downward reaction force in the axial direction to balance this upward repulsive force, thereby preventing the support 4 from moving upward in the axial direction within the aerosol generating device 1.

[0070] Reference Figures 4-6 The bracket 4 of this invention has a supporting end 4.1 and a base end 4.2 arranged axially opposite to each other. A third magnetic body 8 is fixed to the top 21 of the chamber 11. The supporting end 4.1 supports the third magnetic body 8, and a second magnetic body 6 is installed in the base end 4.2. The top 21 is the end axially away from the aerosol generating device body. The third magnetic body 8 can be magnetically attracted to the fourth magnetic body 10 in the second housing 9, so that the first housing 7 is sleeved on the second housing 9. The base end 4.2 and the fixed base 2 form a first thermal insulation distance d1 axially. This arrangement allows the bracket 4 to provide stable support for the third magnetic body 8 while also forming a stable first thermal insulation distance d1 with the fixed base 2. Furthermore, the first magnetic body 5 and the second magnetic body 6 can be high-temperature resistant neodymium iron boron magnets.

[0071] Reference Figure 4 and Figure 7To more stably fix the fixing base 2 within the aerosol generating device 1, the fixing base 2 is typically placed against the inner wall of the first housing 7. However, this causes the fixing base 2 to transfer a significant amount of heat to the inner wall of the first housing 7, resulting in heat loss. Therefore, this invention provides a first protrusion 19 on the second sidewall 2.1 of the fixing base 2 in the radial direction. This first protrusion 19 abuts against the inner wall of the first housing 7 radially, and the area of ​​the first protrusion 19 abutting against the inner wall of the first housing 7 is smaller than the cross-sectional area of ​​the fixing base 2 in a first plane, which is perpendicular to the radial direction. This reduces the contact area between the fixing base 2 and the inner wall of the first housing 7, thereby reducing heat transfer from the fixing base 2 to the inner wall of the first housing 7. Specifically, the first protrusion 19 can also be located on the inner wall of the first housing 7.

[0072] Reference 7- Figure 8 This invention also provides another embodiment, in which the first housing 7 has a first sidewall, and the fixing base 2 has a second sidewall 2.1, forming a second thermal insulation distance d2 between the first sidewall and the second sidewall 2.1. The second thermal insulation distance d2 prevents heat from being transferred from the heating component 3 to the fixing base 2, and then from the fixing base 2 to the chamber 11. Preferably, the second thermal insulation distance d2 is 0.1mm-10mm. Setting it within this range allows for stable installation of the fixing base 2 while effectively preventing heat transfer.

[0073] Continue to refer to Figure 4 The limiting surface 12 shown in this utility model includes a first limiting surface 12.1 and a second limiting surface 12.2. The first limiting surface 12.1 is located at the top end 21 of the chamber 11. The supporting end 4.1 and the first limiting surface 12.1 abut against each other along the axial direction. The bracket 4 can be fixed by the first limiting surface 12.1 and the second limiting surface 12.2. Specifically, in order to prevent the bracket 4 from moving upward along the axial direction, as mentioned above, this utility model provides a first limiting surface 12.1. Once the bracket 4 moves upward along the axial direction, the first limiting surface 12.1 will be subjected to an upward force along the axial direction. At the same time, the first limiting surface 12.1 will generate a downward reaction force along the axial direction to counteract the movement tendency. Furthermore, the second limiting surface 12.2 is provided. Once the bracket 4 has a tendency to move upward, the second limiting surface 12.2 will counteract the movement tendency, thereby ensuring that the bracket 4 is always fixed in the set position.

[0074] Reference Figure 9 and combined Figure 5-6In this application, the limiting surface 12 is specifically designed such that the inner wall of the chamber 11 has a recess 17, the recess 17 has a second limiting surface 12.2, and the base end 4.2 abuts against the second limiting surface 12.2. The base end 4.2 is provided with a step 18 that mates with the recess 17. By mates the step 18 with the recess 17, a stable installation of the base end 4.2 and the chamber 11 can be achieved.

[0075] Furthermore, the supporting end 4.1 and the base end 4.2 of this utility model can be fitted against the inner wall of the chamber 11. This arrangement not only allows for the axial fixation of the bracket 4, but also for the fixation of other parts of the bracket 4, ensuring that the overall structure of the bracket 4 is stably located within the chamber 11.

[0076] Furthermore, such as Figure 2 and Figure 4 To prevent scratching when the second housing 9 is fitted over the first housing 7, the aerosol generating device provided by this invention also includes a buffer body 13. This buffer body 13 can be disposed inside the second housing 9. When the second housing 9 is fitted over the first housing 7, since the first housing 7 has an outer contact surface and the second housing 9 has an inner contact surface opposite to the outer contact surface, the buffer body 13 is located between the inner and outer contact surfaces after installation. Specifically, when the second housing 9 is fitted over the first housing 7, the second housing 9 has an inner contact surface opposite to the inner and outer contact surfaces of the first housing 7. Furthermore, the buffer body 13 can also be used to support the fourth magnetic body 10. Further, the buffer body 13 of this application can also be provided with a second protrusion 22, which extends axially. When the second housing 9 is fitted over the first housing 7, the second protrusion 22 will abut against the outer interface of the first housing 7, thereby preventing relative rotation or shaking between the first housing 7 and the second housing 9. This arrangement ensures that the first housing 7 and the second housing 9 only move along the axial direction, preventing rotation in other directions. Specifically, at least four second protrusions 22 are provided, with two second protrusions 22 arranged radially opposite each other on the left and right sides of the heating element 3, and the other two second protrusions 22 arranged opposite each other at the front and rear of the heating element 3. This arrangement can effectively prevent the second housing 9 from rotating or shaking relative to the first housing 7.

[0077] like Figure 1As shown, the aerosol generating device provided by this utility model further includes a power supply unit 20 and a heat insulation component 14. The first housing 7 and the fixed base 2 are fixedly connected to the housing structure accommodating the power supply unit 20. The power supply unit 20 is axially located behind the heating component 3, and the heat insulation component 14 is axially located between the fixed base 2 and the power supply unit 20. The power supply unit 20 includes a power source and a control board. When the aerosol generating device is turned on, the control board controls the power supply to the heating component 3 via a circuit. The heating component 3 generates heat energy to heat and atomize the aerosol product, thereby generating smoke for the user to inhale. To prevent heat from the heating component 3 from being transferred to the power supply unit 20, this utility model also provides a heat insulation component 14. The heat insulation component 14 can be made of silicone. This arrangement prevents heat loss to the power supply unit 20, thus preventing the power source from affecting normal operation.

[0078] like Figure 2 As shown, the first housing 7 includes a first receiving chamber 15, and the second housing 9 includes a second receiving chamber 16. The first receiving chamber 15 is used to receive at least a portion of the second receiving chamber 16, and the second receiving chamber 16 is used to receive at least a portion of the aerosol-generated article. Specifically, when the second housing 9 is fitted over the first housing 7, the second receiving chamber 16 is embedded in the first receiving chamber 15.

[0079] Furthermore, such as Figure 2 and Figure 4 As shown, the bracket 4 provided by this utility model includes a first bracket 41 and a second bracket 42, which are arranged opposite each other in the radial direction. A first receiving chamber 15 is located between the first bracket 41 and the second bracket 42. Specifically, the other components connected to the first bracket 41 and their positional relationships also apply to the second bracket 42. For example, the second bracket 42 is located in a chamber 11, which includes a first limiting surface 12.1 and a second limiting surface 12.2. The first limiting surface 12.1 abuts against the second bracket 42 in the axial direction (Z direction in the figure), and the abutment restricts the upward movement of the second bracket 42 in the axial direction. The second bracket 42 also has a supporting end 4.1 and a base end 4.2 arranged opposite each other in the axial direction. A third magnetic body 8 is fixed to the top end 21 of the chamber 11. The supporting end 4.1 is used to support the third magnetic body 8. The second magnetic body 6 is installed in the base end 4.2, which has a step 18 that cooperates with the recess 17. The base end 4.2 and the fixed base 2 form a first heat insulation gap d1 along the axial direction.

[0080] Furthermore, such as Figures 10-11 As shown, the first heat insulation distance d1 in each of the above embodiments is 0.3mm-10mm. Although a larger distance provides better heat insulation, it weakens the repulsive force. In order to achieve both stability and good heat insulation, this invention sets it to 0.3mm-10mm.

[0081] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
