Description

Technical Field

[0001] This utility model relates to the field of aerosol generation technology, and in particular to an aerosol generation device. Background Technology

[0002] The design of the opening structure of the aerosol generating device directly affects the product's portability, structural reliability, and user experience.

[0003] Currently, conventional cover opening structures mainly rely on either magnet repulsion or torsion spring structures, both of which can achieve the basic opening and closing function of the cover of the aerosol generating device.

[0004] Existing magnetic repulsion-type cover opening schemes provide the opening driving force by setting permanent magnets with repulsive polarities. However, this scheme requires reserving space inside the device for magnet installation, which leads to a decrease in structural compactness. The slotted holes for magnet placement also weaken the structural integrity. At the same time, frequent opening and closing operations further cause magnet demagnetization, affecting the device's lifespan. The torsion spring-type cover opening scheme uses spring torque to open and close the cover. Since the torsion spring needs to occupy axial or radial space, it squeezes space in other structures, further limiting the functional expansion of the aerosol generation device. Utility Model Content

[0005] The purpose of this invention is to provide an aerosol generating device that solves the problems of reduced structural compactness, weakened structural integrity, and reduced lifespan caused by the magnetic repulsion type opening structure used in the prior art. At the same time, it can also avoid opening slotted structures, occupying more space for other functional structures, improving structural compactness, and ensuring functional expansion.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] An aerosol generating apparatus, comprising:

[0008] The main body has a mounting position.

[0009] A cover body, which is rotatably connected to the main body, and the cover body has a first state of covering the mounting position and a second state of opening the mounting position;

[0010] The elastic element undergoes elastic deformation and stores elastic potential energy when the cover is switched from the second state to the first state by an external force; the elastic element is used to release the elastic potential energy and undergo elastic recovery to drive the cover to switch from the first state to the second state.

[0011] As an alternative solution for an aerosol generating device, the cover is provided with a connecting part, the main body is provided with a base, and the aerosol generating device further includes a connecting assembly. The connecting assembly is used to rotatably connect the base and the connecting part. The elastic element is sleeved on the connecting assembly so that when the connecting assembly rotates, it can drive the elastic element to undergo elastic deformation and store elastic potential energy.

[0012] As an alternative to the aerosol generating device, the connecting part is provided with a mounting hole extending along the rotation axis of the cover, the elastic element is placed in the mounting hole, and the connecting component is placed in the mounting hole.

[0013] As an alternative to the aerosol generating device, the connecting assembly includes two rotating shafts arranged at intervals along the rotation axis of the cover, and the two rotating shafts are respectively connected to both ends of the elastic element.

[0014] As an alternative to the aerosol generating device, the connecting assembly further includes a first connector and a second connector, wherein the first connector is used for connecting one of the rotating shafts and the connecting portion; and the second connector is used for connecting the other rotating shaft and the base.

[0015] As an alternative to the aerosol generating device, the rotating shaft is inserted into the base at the end away from the elastic element, and the elastic element is compressed between the two rotating shafts.

[0016] As an alternative to the aerosol generating device, the end of the rotating shaft extends outward with two opposing limiting arms, and the two ends of the elastic element are respectively provided with limiting parts, which are sandwiched between the two limiting arms.

[0017] As an alternative to the aerosol generating device, the opposing surfaces of the two limiting arms are planar, and the limiting portion has a linear structure.

[0018] As an alternative to the aerosol generating device, the limiting arm is inserted inside the elastic member.

[0019] As an alternative to the aerosol generating device, the cover is provided with a first snap-fit ​​part, and the main body is provided with a second snap-fit ​​part. When the cover is in the first state, the first snap-fit ​​part and the second snap-fit ​​part snap-fit ​​together.

[0020] Beneficial effects:

[0021] In this invention, the elastic element enables the lid to open automatically by rotating. When the user needs to close the lid, i.e., switch the lid from the second state to the first state, the user can directly press the lid and rotate it to fasten it onto the main body. Simultaneously, the elastic element deforms and stores elastic potential energy during this process. When the user needs to open the lid, i.e., switch the lid from the first state to the second state, the elastic potential energy of the elastic element is released directly, causing the lid to open. This device enables the lid to open automatically using the elastic element, avoiding the need for mounting holes in existing magnetic repulsion-type lid opening structures. This prevents damage to the overall structural integrity of the device and improves its compactness. Furthermore, it avoids the problem of magnet demagnetization due to prolonged operation in applications with frequent lid opening and closing, thus preventing impact on the device's lifespan. It also avoids the need for slotted structures, ensuring structural compactness and facilitating the expansion of other functions of the device. Attached Figure Description

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] Please see the appendix Figure 1 - Appendix Figure 4 This embodiment relates to an aerosol generating device (hereinafter referred to as the "device"). The device includes a main body 1, a cover 2, and an elastic element 3. The main body 1 is provided with a mounting position 11; the cover 2 is rotatably connected to the main body 1, and the cover 2 has a first state of covering the mounting position 11 and a second state of opening the mounting position 11; when the cover 2 switches from the second state to the first state by external force, the elastic element 3 undergoes elastic deformation and stores elastic potential energy; the elastic element 3 is used to release the elastic potential energy and undergo elastic recovery to drive the cover 2 to switch from the first state to the second state.

[0039] Specifically, the main body 1 includes an outer shell and functional components or parts disposed inside the outer shell. A mounting position 11 is provided on the main body 1, allowing the internal functional components or parts to be installed. For example, a power supply, control circuit board, and aerosol generation products can all be disposed within the mounting position 11. The cover 2 is a plate-shaped structure and can be a curved panel adapted to the curved contour of the main body 1. One side of the cover 2 is rotatably connected to the main body 1, allowing the cover 2 to be flipped relative to the main body 1. This flipping operation of the cover 2 achieves a first state where the cover 2 covers the mounting position 11 and a second state where the mounting position 11 is open. When the cover 2 is in the second state, the internal functional components or parts can be smoothly assembled into the mounting position 11. After assembly, the cover 2 is placed back into the first state, thus ensuring the airtightness of the entire device and protecting the internal functional components or parts.

[0040] The aerosol generating device also includes a heating element (not shown), which is used to heat the aerosol generating product placed in the mounting position 11, thereby causing at least a portion of the active substances in the aerosol generating product to evaporate and generate aerosol, and releasing the aerosol into the cavity in the mounting position 11. The aerosol generating device also includes a suction nozzle 6, which is provided with an air outlet (not shown) that communicates with the cavity in the mounting position 11, so that the user can inhale the aerosol by sucking on the suction nozzle 6.

[0041] The heating element may include any one of a resistance heating element, an infrared heating element, or a microwave heating element. Alternatively, in some embodiments, the heating element may also be a sensor, and the aerosol generating device may also include a magnetic field generator for generating a changing magnetic field, such as an induction coil. This changing magnetic field passes through the sensor, thereby generating eddy currents in the sensor under the action of electromagnetic induction, causing the sensor to heat up. The elastic element 3 can be used to automatically flip and open the cover 2. Specifically, when the user needs to close the cover 2, that is, when the cover 2 is switched from the second state to the first state, the user can directly press the cover 2 and make it rotate and fasten onto the main body 1. At the same time, the elastic element 3 undergoes elastic deformation and stores elastic potential energy during this process. When the user needs to open the cover 2, that is, when the cover 2 is switched from the first state to the second state, the elastic potential energy of the elastic element 3 can be directly released to drive the cover 2 to open.

[0042] This device enables the cover 2 to open automatically using the elastic element 3, avoiding the magnetic repulsion opening structure used in existing technologies. This avoids the need for holes in the overall structure, thus preventing damage to the integrity of the device and improving its compactness. Furthermore, it prevents the magnet from demagnetizing due to prolonged operation in applications where the cover 2 is frequently opened and closed, thus extending the device's lifespan. It also eliminates the need for slots, ensuring structural compactness and facilitating the expansion of other functions within the device.

[0043] Optionally, the cover 2 is provided with a connecting part 21, the main body 1 is provided with a base 4, and the device also includes a connecting component 5. The connecting component 5 is used to rotatably connect the base 4 and the connecting part 21. The elastic element 3 is sleeved on the connecting component 5 so that when the connecting component 5 rotates, it can drive the elastic element 3 to undergo elastic deformation and store elastic potential energy.

[0044] Specifically, the base 4 can be screwed and fixed inside the main body 1 by various threaded fasteners. At the same time, the base 4 and the cover 2 can be directly hinged by the connecting component 5. The elastic element 3 can be a common standard spring, which is sleeved on the connecting component 5 and the two ends of the elastic element 3 are limited by the connecting component 5. So when the cover 2 is flipped relative to the main body 1, the elastic element 3 undergoes torsional deformation and stores elastic potential energy. When it is necessary to open the cover 2, the elastic element 3 restores its deformation to release the elastic potential energy and completes the flipping of the cover 2.

[0045] In this embodiment, the connecting component 5, in conjunction with the base 4 and the connecting part 21, achieves a rotatable connection between the cover 2 and the main body 1. Since there is relative rotation between the base 4 and the connecting part 21, wear is easily generated on the sliding contact surface. When the base 4 wears out, the device can continue to be used simply by replacing the base 4, thereby improving replaceability and practicality.

[0046] Furthermore, the connecting part 21 is provided with a mounting hole 211 extending along the rotation axis of the cover 2, the elastic member 3 is placed in the mounting hole 211, and the connecting component 5 is partially placed in the mounting hole 211.

[0047] Specifically, the connecting part 21 can be integrally formed on one side of the cover 2. The connecting part 21 is columnar in the direction of the rotation axis and has a circular mounting hole 211 along the rotation axis. The elastic member 3 is completely placed inside the mounting hole 211. Part of the structure of the connecting component 5 is placed inside the mounting hole 211, and both ends of the connecting component 5 are respectively placed outside the mounting hole 211.

[0048] In this embodiment, by completely placing the elastic element 3 inside the mounting hole 211, the deformable element is prevented from being exposed to the outside, which improves the aesthetics. At the same time, it can also ensure that the deformed elastic element 3 is always confined inside the connection part 21, providing stable support for the elastic element 3 and improving the working stability of the elastic element 3.

[0049] Optionally, the connecting assembly 5 includes two rotating shafts 51 arranged at intervals along the rotation axis of the cover 2, and the two rotating shafts 51 are respectively connected to both ends of the elastic member 3.

[0050] Specifically, a portion of the structure of the two rotating shafts 51 is inserted into the mounting hole 211, and a portion of the structure of the two rotating shafts 51 is connected to both ends of the elastic member 3, while the remaining portions of the two rotating shafts 51 are exposed outside the mounting hole 211.

[0051] In this embodiment, two rotating shafts 51 are more conducive to processing than a single hinge shaft, and are also easier to assemble with the elastic element 3, thereby improving the assembly processability.

[0052] Furthermore, the connecting assembly 5 also includes a first connector 52 and a second connector 53. The first connector 52 is used for the connection between one of the rotating shafts 51 and the connecting part 21; the second connector 53 is used for the connection between the other rotating shaft 51 and the base 4.

[0053] In this embodiment, the rotating shaft 51 is inserted into the base 4 at the end away from the elastic member 3. Specifically, two clamping parts 41 are formed on the base 4, and a clamping space is formed between the two clamping parts 41. Part of the structure of the connecting part 21 is placed in the clamping space. At the same time, the two ends of the mounting hole 211 are respectively opposite to the clamping parts 41. A stepped hole 411 is provided through the clamping part 41 at the position opposite to the mounting hole 211, so the stepped hole 411 is connected to the mounting hole 211. One of the rotating shafts 51, after being connected to the elastic element 3, can pass through the stepped hole 411 on one side and enter the mounting hole 211. The other rotating shaft 51 passes through the stepped hole 411 on the other side and enters the mounting hole 211, thus completing the connection with the elastic element 3. The rotating shaft 51 is provided with an annular stepped platform 512. When the rotating shafts 51 on both sides are inserted to the preset depth of the stepped hole 411, the stepped platform 512 of the rotating shaft 51 abuts against the stepped surface of the stepped hole 411, thereby limiting the axial insertion depth of the rotating shaft 51 to ensure accurate assembly position and improve assembly efficiency.

[0054] Furthermore, both the first connector 52 and the second connector 53 can be tapered pins. Correspondingly, pin holes that mate with the first connector 52 and the second connector 53 are respectively provided on the connecting part 21 and the base 4. During the assembly process, the first connector 52 is first inserted into the pin hole of the connecting part 21, and then correspondingly inserted into the corresponding hole of one of the rotating shafts 51. After reaching a preset depth, the first connector 52 is interference-fitted with the pin hole, thereby realizing the connection between one of the rotating shafts 51 and the connecting part 21. Then, the second connector 53 is inserted into the pin hole of the base 4, and correspondingly inserted into the corresponding hole of the other rotating shaft 51. After reaching a preset depth, the second connector 53 is interference-fitted with the pin hole, thereby realizing the connection between the other rotating shaft 51 and the base 4. Finally, the entire base 4 is screwed onto the main body 1, completing the assembly of the rotating connection structure of the cover 2 and the main body 1.

[0055] Optionally, the elastic element 3 is compressed between the two rotating shafts 51.

[0056] Specifically, after one of the rotating shafts 51 is connected to the connecting part 21 and the other rotating shaft 51 is connected to the base 4, the distance between the two rotating shafts 51 is less than the free length of the elastic member 3, so that the elastic member 3 is in a compressed state.

[0057] In this embodiment, after the rotating structure of the device is assembled, the elastic element 3 is always in a compressed state. Generally, when the device is in use, the main body 1 is usually kept relatively fixed, the cover 2 automatically springs open relative to the main body 1 by the action of the elastic element 3, and the base 4 is fixed on the main body 1. The rotating shaft 51 connected to the base 4 through the second connector 53 also remains relatively stationary, while the rotating shaft 51 connected to the connecting part 21 through the first connector 52 will rotate relative to the base 4 inside the stepped hole 411. In this embodiment, by keeping the elastic element 3 in a compressed state, the compressed elastic element 3 will apply a certain thrust to the rotating shaft 51, thereby effectively preventing the rotating shaft 51 from shaking or making abnormal noise when rotating inside the base 4, and improving the stability of the rotating structure.

[0058] Please refer to the appendix for further details. Figure 3 - Appendix Figure 5 The end of the rotating shaft 51 extends outward with two opposing limiting arms 511. The two ends of the elastic member 3 are respectively provided with limiting parts 31, which are sandwiched between the two limiting arms 511.

[0059] Specifically, the two limiting arms 511 can be integrally formed at the end of the rotating shaft 51, and the free ends of the limiting portions 31 are machined with rounded corners or chamfers to facilitate the insertion of the limiting arms 511 into the elastic member 3. A clamping area is formed between the two limiting arms 511 to clamp the limiting portions 31 of the elastic member 3. In this embodiment, in order to ensure the transmission of the torsional force to the elastic member 3 and to simplify the structure, the limiting portions 31 are directly bent into straight rods and placed horizontally between the two limiting arms 511. Of course, in other embodiments, the limiting portions 31 of the elastic member 3 can further adopt other structural schemes to form an end structure that can be accommodated in the above clamping area. Of course, the shape of the end structure can be various, and can be comprehensively adjusted according to factors such as the difficulty of molding and the convenience of assembly.

[0060] In this embodiment, the outer wall surface of the two limiting arms 511 is a partially cylindrical surface adapted to the internal circular structure of the elastic member 3. The two limiting arms 511 are placed inside the elastic member 3. When the elastic member 3 deforms, the limiting arms 511 of the two rotating shafts 51, combined with the inner wall of the mounting hole 211, can provide support for the elastic member 3, thereby enabling the elastic member 3 to maintain dynamic stability during frequent deformation and deformation recovery, and improving the reliability of the device.

[0061] Furthermore, the opposing surfaces of the two limiting arms 511 are planar, and the limiting part 31 has a linear structure.

[0062] Specifically, the clamping area formed by the two limiting arms 511 is U-shaped, and the inner surface of the U-shaped clamping area is a plane, with the gap between the two planes being slightly larger than the width of the limiting part 31.

[0063] In this embodiment, the above-mentioned structural forms of the limiting arm 511 and the limiting part 31 not only facilitate processing and forming, but also further facilitate the positioning and assembly between the rotating shaft 51 and the elastic element 3, thereby improving assembly efficiency and assembly processability.

[0064] Optionally, the cover 2 is provided with a first snap-fit ​​part 22, and the main body 1 is provided with a second snap-fit ​​part 12. When the cover 2 is in the first state, the first snap-fit ​​part 22 and the second snap-fit ​​part 12 snap-fit ​​together.

[0065] In this embodiment, the specific structure of the engagement between the first latching part 22 and the second latching part 12 can be designed according to relevant requirements. For example, based on the simplification of the device structure, the engagement between the first latching part 22 and the second latching part 12 can be a hook and slot engagement structure or a conventional snap-fit ​​connection structure. Based on the user's need for effortless operation, a transmission mechanism such as a lever or other energy storage mechanisms can be added to facilitate the user to trigger the first latching part 22 and the second latching part 12 to release the engagement with a smaller force.

[0066] This embodiment does not limit the specific structure of the first latching part 22 and the second latching part 12. It is only necessary to ensure that when the cover 2 is in the first state, the first latching part 22 and the second latching part 12 can maintain a stable latching connection, and when it is necessary to switch the cover 2 to the second state, the user can directly trigger and release the latching relationship between the first latching part 22 and the second latching part 12, so that the cover 2 can automatically pop open.

[0067] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. 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. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
