Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, specifically to a heating non-combustible device. Background Technology

[0002] A heated non-combustible device is an aerosol generating device that heats an aerosol product to produce aerosol without combustion. Heated non-combustible devices typically have a product inlet and a heating chamber. The aerosol product can be inserted into the heating chamber through the product inlet so that it can be heated by the heating components inside the device.

[0003] To meet various usage requirements, some heated non-combustible devices typically integrate different functional modules. For example, to prevent foreign objects from entering the device through the insert, an openable and closable cover is installed on the insert; a fixing mechanism is included to secure the aerosol product inserted into the insert; and an insertion self-starting module is incorporated to enable automatic activation after the aerosol product is inserted. The more functions required, the more complex the structure of the heated non-combustible device becomes, which is detrimental to design and manufacturing. Utility Model Content

[0004] This application provides a new type of heating non-combustion device to reduce the structural complexity of the heating non-combustion device.

[0005] One embodiment provides a heating non-combustible device, comprising:

[0006] The device housing has a product insertion port for inserting aerosol products.

[0007] The cap is configured to have a travel relative to the housing of the device, the travel having a first position covering the article inlet and a second position opening the article inlet and causing the cap to abut against the outer peripheral surface of the aerosol article inserted into the article inlet;

[0008] The device includes a first magnetic component and a second magnetic component. The first magnetic component is fixed to the outer casing of the device, and the second magnetic component is fixed to the cover. There is a magnetic force between the first magnetic component and the second magnetic component. When the cover is located in the second position or between the first position and the second position, it tends to move towards the first position under the action of the magnetic force.

[0009] In one embodiment, the first magnetic element and the second magnetic element have magnetic poles with the same magnetic properties on the side that are close to each other along the insertion and removal direction of the product socket, so that the magnetic force is a repulsive force.

[0010] The first position is located at one end of the travel. When the cover moves to the first position or the second position, the second magnetic element is located on the first side of the first magnetic element along the direction of movement of the cover, and the second magnetic element located at the second position is closer to the first magnetic element than the second magnetic element located at the first position.

[0011] In one embodiment, the travel further includes a third position for opening the article slot, the third position being located at the other end of the travel, wherein when the cap moves to the third position, the second magnetic element is located on the second side of the first magnetic element along the direction of movement of the cap.

[0012] In one embodiment, the heated non-combustible device further includes a magnetic field strength detection unit, which is disposed close to the first magnetic element and is used to generate a switching signal in response to the magnetic field strength generated by the first magnetic element and the second magnetic element when the cover is positioned in the second position.

[0013] In one embodiment, the cover is slidably disposed on the device housing.

[0014] In one embodiment, the device housing has a groove arranged along a first direction, the cover is slidably fitted into the groove along the first direction, the first magnetic element and the product insertion port are arranged side by side in the groove along the first direction, and the product insertion port is located at one end of the bottom wall of the groove along the first direction.

[0015] In one embodiment, the first magnetic element and the second magnetic element have magnetic poles with the same magnetic properties on the side that are close to each other along the insertion and removal direction of the product socket, so that the magnetic force is a repulsive force.

[0016] The first magnetic element is disposed at the middle of the bottom wall of the slide along the first direction, so that the stroke also has a third position in which the product insertion port is opened. The cap in the third position is located at the end of the slide away from the product insertion port, and the magnetic force is used to position the cap in the third position.

[0017] In one embodiment, the bottom wall of the chute is provided with a first cavity facing the opening of the cover, the first magnetic element is fixed in the first cavity and exposed in the chute; the cover is provided with a second cavity facing the bottom wall of the chute, the second magnetic element is fixed in the second cavity and exposed outside the cover.

[0018] In one embodiment, the cavity sidewall of the first cavity extends to the bottom wall of the groove that protrudes from the slide to form a convex ring, such that the depth of the first cavity is not less than the thickness of the first magnetic element, and the first magnetic element is completely contained in the first cavity.

[0019] In one embodiment, the cover is provided with an avoidance recess along the sliding direction to avoid the protruding ring portion when the cover slides.

[0020] According to the above-described embodiment of the heat-not-burning device, by providing a cover that can move relative to the outer shell of the device, and by providing a first magnetic element and a second magnetic element on the cover and the outer shell of the device respectively, the cover can both cover the product insertion port at a first position and press against the aerosol product inserted into the product insertion port at a second position, so as to limit the accidental release of the aerosol product. This allows the cover structure to achieve both the dustproof function of the product insertion port and the positioning function of the aerosol product, which helps to improve the functional integration of the device, reduce the structural complexity, and facilitate design and production.

[0036] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0037] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0038] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0039] The heated non-combustible device includes a product inlet 110 for inserting an aerosol product 700. After the aerosol product 700 is inserted into the device through the product inlet 110, it is heated by a heating element 500 to generate an aerosol. In some related technologies, the heated non-combustible device also includes a dustproof module, such as a cover 200 for covering the product inlet 110 to prevent foreign objects from entering the device through the product inlet 110. Especially for heated non-combustible devices with an automatic start function after the aerosol product 700 is inserted, the dustproof module can reduce the risk of the device being accidentally started by foreign objects.

[0040] However, in these devices, various functions (such as dust prevention, product insertion self-starting function, and product fixing function) are usually implemented by independent modules, which makes the structure of the heating non-combustible device more complex and not conducive to design and manufacturing.

[0041] In this embodiment, by providing a cover 200 that is movable relative to the device housing 100, and by providing a first magnetic element 300 and a second magnetic element 400 on the cover 200 and the device housing 100 respectively, the cover 200 can both cover the product insertion port 110 at a first position and press against the aerosol product 700 inserted in the product insertion port 110 at a second position, thereby preventing the aerosol product 700 from accidentally falling out. This allows the cover 200 structure to achieve both dustproof function and positioning function for the aerosol product 700, which helps to improve the functional integration of the device, reduce structural complexity, and facilitate design and production.

[0042] One embodiment provides a heating non-combustible device, please refer to... Figures 1 to 8 The heated non-combustible device includes a housing 100, a cover 200, and other components provided as needed.

[0043] Please refer to Figure 1 and Figure 2 The device housing 100 can be understood as the main component that forms the outer contour of the heated non-combustible device. The heated non-combustible device can be held, moved, and used using the device housing 100. The device housing 100 has a product insertion port 110 for inserting the aerosol product 700.

[0044] For example, the device housing 100 is cylindrical, and the product insertion port 110 is located at one end of the device housing 100. Furthermore, the heat-not-burn device may also include a heating element 500, which is disposed inside the device. The heating element 500 has a heating chamber 510 with an opening directly opposite the product insertion port 110, allowing the aerosol product 700 to be inserted into the heating chamber 510 through the product insertion port 110 and heated by the heating element 500 to generate an aerosol.

[0045] Please refer to Figure 1 and Figure 3 The cover 200 is configured to have a stroke that moves relative to the device housing 100, the stroke having: a first position (e.g. Figure 1 As shown), at this position, cover 200 to cover the insert 110 of the article; and at the second position (as shown) Figure 3 As shown, in this position, the cover 200 opens the product insertion port 110, and when the aerosol product 700 is inserted into the product insertion port 110, the cover 200 abuts against the outer peripheral surface of the aerosol product 700. The abutment of the cover 200 against the outer peripheral surface of the aerosol product 700 inserted into the product insertion port 110 allows the aerosol product 700 to be clamped and positioned in the product insertion port 110. This structure of the cover 200 can achieve both dust prevention and product positioning functions of the device, which helps to reduce the structural complexity of the device.

[0046] It is understandable that various methods can be used to ensure that the cap 200 remains in contact with the outer peripheral surface of the aerosol product 700 when in the second position. For example, an elastic element can be incorporated into the cap 200 to provide pressure against the aerosol product 700 using the elastic force of the elastic element. Alternatively, the cap 200 can be constructed to require overcoming significant static friction to drive its movement, thus allowing the cap 200 to remain in the second position after user operation. However, regardless of whether it relies on the elastic force of the elastic element or static friction, after repeated use, it is prone to failure due to fatigue, wear, and other factors affecting the relevant components.

[0047] In one embodiment, please refer to Figure 2 and Figure 4 The heated non-combustible device also includes a first magnetic element 300 and a second magnetic element 400. The first magnetic element 300 is fixed on the outer shell 100 of the device, and the second magnetic element 400 is fixed on the cover 200. There is a magnetic force between the first magnetic element 300 and the second magnetic element 400. When the cover 200 is in the second position or between the first position and the second position, it tends to move towards the first position under the action of the magnetic force, so that when the cover 200 is in the second position, it can continuously maintain pressure on the outer peripheral surface of the aerosol product 700 inserted in the product socket 110.

[0048] It is understood that the magnetic force between the first magnetic component 300 and the second magnetic component 400 can be either an attractive force or a repulsive force. Depending on the specific setting position of the first magnetic component 300 and the second magnetic component 400, the dustproof and product positioning functions of the cover 200 can be achieved.

[0049] In one embodiment where the magnetic force is repulsive, please refer to... Figure 2 and Figure 4The first magnetic component 300 and the second magnetic component 400 can have the same magnetic poles on adjacent sides of the product insertion port 110, making the magnetic force a repulsive force. The "product insertion / removal direction" refers to the direction in which the aerosol product 700 is inserted or removed, such as... Figure 2 Axial direction of the insert 110 in the middle product.

[0050] Furthermore, the first position can be located at one end of the travel. When the cover 200 moves to the first or second position, the second magnetic element 400 is located on the first side of the first magnetic element 300 along the direction of movement of the cover 200. The second magnetic element 400 at the second position is closer to the first magnetic element 300 than the second magnetic element 400 at the first position. This prevents the cover 200 from moving further to the first position when it moves to the second position due to the obstruction of the aerosol product 700 inserted in the product slot 110. The cover 200 is thus positioned at the second position by pressing against the outer circumferential surface of the aerosol product 700, thereby achieving the positioning of the aerosol product 700. When no aerosol product 700 is inserted in the product slot 110, the cover 200 can pass through the second position under the action of magnetic force and is ultimately restricted to the first position.

[0051] In a further embodiment, please refer to Figure 5 and Figure 6 In order to facilitate the insertion of the aerosol product 700 into the product socket 110, the stroke can also have a third position with the product socket 110 open. The third position is located at the other end of the stroke. When the cover 200 moves to the third position, the second magnetic element 400 is located on the second side of the first magnetic element 300 along the direction of movement of the cover 200, so that the cover 200 can be held in the third position under the action of magnetic force.

[0052] In another embodiment where the magnetic force is attractive, the first magnetic element 300 and the second magnetic element 400 may have opposite magnetic poles on the side of the article insertion / removal direction of the article socket 110, so that the magnetic force is mutually attractive. The first position can be located in the middle of the stroke, such that when the cover 200 is in the first position, the first magnetic element 300 and the second magnetic element 400 are facing each other, and when the cover 200 is in the second position, the first magnetic element 300 and the second magnetic element 400 are located on opposite sides of the article socket 110, thereby using the mutual attraction between the first magnetic element 300 and the second magnetic element 400 to provide a pressure against the aerosol article 700 to the cover 200. Of course, in other embodiments where the magnetic force is attractive, one of the first magnetic element 300 and the second magnetic element 400 can also be replaced with a magnetic conductor (such as a ferromagnetic material) that can be attracted by the other.

[0053] Furthermore, it is understood that the specific manner in which the cover 200 is movably disposed on the device housing 100 is not limited. For example, in one embodiment, please refer to... Figure 2 The cover 200 can be slidably disposed on the device housing 100, and the sliding trajectory can be a straight line or an arc, so as to achieve switching between different positions by sliding. In another embodiment, the cover 200 can be hinged to the device housing 100, so that the cover 200 can be rotated about the hinge axis, thereby achieving switching between different positions.

[0054] In one embodiment, please refer to Figure 2 and Figure 4 The device housing 100 has a slide groove 120 arranged along a first direction. The cover 200 is slidably assembled in the slide groove 120 along the first direction. The first magnetic element 300 and the product insertion port 110 are arranged side by side in the slide groove 120 along the first direction, and the product insertion port 110 is located at one end of the bottom wall of the slide groove 120 along the first direction, so that when the cover 200 slides in the slide groove 120 along the first direction, it can approach the product insertion port 110, and when it slides along the second direction opposite to the first direction, it can move away from the product insertion port 110.

[0055] In one embodiment, please refer to Figure 2 , Figure 4 and Figure 6 The first magnetic element 300 and the second magnetic element 400 have identical magnetic poles on the side of the product insertion / removal direction of the product socket 110, so that the magnetic force is a repulsive force. Furthermore, the first magnetic element 300 is disposed in the middle of the bottom wall of the slide groove 120 along the first direction, so that the stroke also has a third position with the product socket 110 open. The cover 200 in the third position is located at the end of the slide groove 120 away from the product socket 110, and the magnetic force is used to position the cover 200 in the third position.

[0056] For example, a product insertion port 110 is provided on the bottom wall of one end of the slide 120. The first position is located at the end of the slide 120 where the product insertion port 110 is provided, and the third position is located at the other end of the slide 120. The first magnetic element 300 is fixed to the middle of the bottom wall of the slide 120 along the first direction and is spaced apart from the product insertion port 110. When the cover 200 is in the second position, the second magnetic element 400 is located on the side of the first magnetic element 300 close to the product insertion port 110 along the first direction, that is, between the first magnetic element 300 and the product insertion port 110. At this time, the first magnetic element 300 and the second magnetic element 400 have a large magnetic force due to their close distance, which helps to press the aerosol product 700 inserted in the product insertion port 110 tightly and improve the positioning effect.

[0057] In one embodiment, please refer to Figure 7 and Figure 8The bottom wall of the chute 120 may be provided with a first cavity 121 opening towards the cover 200. The first magnetic element 300 is fixed in the first cavity 121 and exposed in the chute 120. The cover 200 may be provided with a second cavity 210 opening towards the bottom wall of the chute 120. The second magnetic element 400 is fixed in the second cavity 210 and exposed outside the cover 200. The facing openings of the first cavity 121 and the second cavity 210 help to eliminate the obstruction between the first magnetic element 300 and the second magnetic element 400, thereby maximizing the magnetic force and making it easier for the cover 200 to be held in various desired positions.

[0058] In one embodiment, please refer to Figure 7 and Figure 8 The sidewall of the first cavity 121 can extend to the bottom wall of the protruding groove 120 to form a convex ring 122, such that the depth of the first cavity 121 is not less than the thickness of the first magnetic element 300, and the first magnetic element 300 is completely accommodated in the first cavity 121. This helps to maintain the fixing effect on the first magnetic element 300 when the thickness of the first magnetic element 300 is greater than the thickness of the bottom wall of the groove 120. In addition, the convex ring 122 can also protect the first magnetic element 300 to limit the contact between the cover 200 and the first magnetic element 300 when the cover 200 slides, reducing the risk of displacement of the first magnetic element 300 under pressure.

[0059] The specific fixing method of the first magnetic element 300 and the second magnetic element 400 is not limited. For example, in some embodiments, protrusions can be provided on the cavity sidewalls of the first cavity 121 and the second cavity 210 to abut and position the corresponding first magnetic element 300 and the second magnetic element 400. An adhesive layer can also be provided in the first cavity 121 and the second cavity 210 to bond and fix the corresponding first magnetic element 300 and the second magnetic element 400.

[0060] In one embodiment, to avoid the protruding ring 122 interfering with the sliding of the cover 200, please refer to... Figure 7 The cover 200 may be provided with a relief recess 220 along the sliding direction to avoid the protruding ring 122 when the cover 200 slides.

[0061] For example, please refer to Figure 7 and Figure 8 The groove 120 may have slots 123 on the sidewalls of the groove along the extension direction. The cover 200 includes sliding engagement parts 230 that are slidably engaged in the slots 123 on both sides. The avoidance recess 220 is formed between the two sliding engagement parts 230.

[0062] In one embodiment, please refer to Figure 8The device housing 100 includes a recessed portion 130 and a cover plate portion 140 covering the recessed portion 130. The recessed portion 130 and the cover plate portion 140 together form a sliding groove 120, and the opening of the sliding groove 120 is provided on the cover plate portion 140. By providing the cover plate portion 140, the cover 200 can be assembled into the recessed portion 130 and then the cover plate portion 140 is placed on top to limit the cover 200 in the sliding groove 120, which facilitates the assembly of the cover 200.

[0063] In one embodiment, please refer to Figure 2 , Figure 4 and Figure 6 The heated non-combustible device may also include a magnetic field strength detection unit 600, which is located close to the first magnetic element 300. The magnetic field strength detection unit 600 is used to generate a switching signal in response to the magnetic field strength generated by the first magnetic element 300 and the second magnetic element 400 when the cover 200 is positioned in the second position. The generated switching signal can be used to trigger the heated non-combustible device to start heating. For example, it can be connected to the heating element 500 in the heated non-combustible device through a control module, so as to trigger the heated non-combustible device to start heating when it is determined that the cover 200 is held in the second position, so as to further integrate the product insertion self-starting function.

[0064] The magnetic field strength detection unit 600 can be a Hall element and can be disposed in the inner cavity of the device housing 100. Taking the above-mentioned heating non-combustible device in which the cover 200 is slidably disposed in the groove 120 and the first magnetic element 300 is located in the middle of the bottom wall of the groove 120 as an example, the magnetic field strength detection unit 600 can be fixed between the first magnetic element 300 and the product insertion port 110, that is, it is set at the position of the second magnetic element 400 corresponding to the position of the cover 200 when it is in the second position (e.g., Figure 4 (As shown).

[0065] Before using the device, the user first adjusts the cap 200 from the first position to the third position to open the product insertion port 110, and then inserts the aerosol product 700. Then, the user adjusts the cap 200 from the third position to the second position along the first direction. During this process, the magnetic field strength detected by the magnetic field strength detection unit 600 gradually increases. Once it reaches a preset value (such as the theoretical magnetic field strength value that the magnetic field strength detection unit 600 should detect when the cap 200 is in the second position), a switch signal is generated, triggering the heating-non-combustible device to start heating. When the aerosol product 700 is pulled out, the cap 200 continues to move towards the first position along the first direction under the action of magnetic force. During this process, the magnetic field strength detected by the magnetic field strength detection unit 600 gradually decreases. When it falls below the preset value, a switch signal is generated to trigger the heating-non-combustible device to stop heating.

[0066] In some embodiments, the heated non-combustible device can also be configured to start heating only when the magnetic field strength detection unit 600 detects that the magnetic field strength has reached a preset value and maintains it for a sufficient time (e.g., 2 seconds), so as to reduce the risk of the heated non-combustible device being started erroneously.

[0067] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
