Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to an aerosol generating device. Background Art

[0002] Aerosols are colloidal dispersion systems formed by solid or liquid particles dispersed and suspended in a gaseous medium. Because aerosols can be absorbed by the human body through the respiratory system, they provide users with a novel alternative absorption method. An aerosol generating device refers to a device that forms aerosols from stored atomizable media through heating or ultrasound. Atomizable media include liquid, gel, paste, or solid aerosol generating matrices. Atomizing these media delivers inhalable aerosols to users, replacing conventional product forms and absorption methods.

[0003] Some existing aerosol generating devices have an insertion port for inserting a columnar aerosol generating substrate. Users simply insert the substrate into the device to heat it for use. However, to prevent dust and debris from entering the insertion port and ensure the cleanliness of the device's interior, the port needs to be sealed with a dust cover when no aerosol generating substrate is inserted. But current dust covers are mostly exposed on the device's exterior, making them prone to damage and affecting the device's appearance and aesthetics. Summary of the Invention

[0004] Therefore, it is necessary to provide an aerosol generating device to address the problem that dust covers are easily damaged and affect aesthetics.

[0005] An aerosol generating apparatus, comprising:

[0006] The main housing has a receiving cavity inside and an insertion port communicating with the receiving cavity.

[0007] A dustproof component, movably housed within the receiving cavity; and

[0008] A drive assembly is at least partially housed within the receiving cavity and is driveably connected to the dustproof component. The drive assembly can controllably drive the dustproof component to reciprocate so that one end of the dustproof component opens or closes the insertion port.

[0009] In one embodiment, the main housing has a control slot spaced apart from the insertion port, and the drive assembly partially exposes the control slot.

[0010] In one embodiment, the drive assembly includes a control element and a transmission unit, the control element protruding from the control slot, the transmission unit being housed within the receiving cavity, and the control element being drively connected to the dustproof component via the transmission unit.

[0011] In one embodiment, the control member is rotatably disposed on the main housing, with a portion of the outer circumferential surface of the control member exposed above the control groove.

[0012] In one embodiment, the transmission unit includes:

[0013] The first transmission component is coupled to the control component and rotates synchronously with the control component;

[0014] The second transmission component is tractively connected to the dustproof component; and

[0015] An intermediate transmission component is connected between the first transmission component and the second transmission component.

[0016] In one embodiment, the first transmission member and the intermediate transmission member are arranged sequentially along the moving direction of the dustproof member, and the dustproof member is located on one side of the transmission unit in a direction perpendicular to the moving direction of the dustproof member.

[0017] In one embodiment, the intermediate transmission member and the second transmission member are rotatably disposed on the main housing, and the intermediate transmission member meshes with the first transmission member and the second transmission member respectively.

[0018] In one embodiment, the second transmission member is rotatably disposed on the main housing, and the intermediate transmission member is disposed around the first transmission member and the second transmission member.

[0019] In one embodiment, the second transmission member is rotatably disposed on the main housing, and the second transmission member meshes with the dustproof member.

[0020] In one embodiment, the second transmission member is a gear, and the dustproof member has a rack that meshes with the second transmission member, the rack extending along the moving direction of the dustproof member.

[0021] The aforementioned aerosol generating device, since the dustproof components are completely housed within the receiving cavity of the main housing, can prevent the dustproof components from being easily damaged due to exposure, while also improving the aesthetics of the aerosol generating device and meeting the growing aesthetic demands of users.

[0035] Referring to Figure 1, one embodiment of this application provides an aerosol generating device 100 for heating an aerosol generating matrix to generate aerosols for user use. The heating method can be convection, conduction, radiation, or a combination thereof. The aerosol generating matrix is ​​preferably a columnar solid. The aerosol generating matrix includes, but is not limited to, materials used for medical, health, and cosmetic purposes; for example, the aerosol generating matrix is ​​plant-based materials, such as plant roots, stems, leaves, flowers, buds, and seeds.

[0036] Please refer to Figures 1 to 3. The aerosol generating device 100 includes a main housing 10, a dustproof component 30, and a drive assembly 50. The main housing 10 has a receiving cavity 12 and a storage chamber 72 located within the receiving cavity 12. One end of the main housing 10 also has an insertion port 14 communicating with the storage chamber 72, through which the aerosol generating matrix can be inserted into the storage chamber 72. The dustproof component 30 is movably housed within the receiving cavity 12 and located outside the storage chamber 72. The drive assembly 50 is at least partially housed within the receiving cavity 12 and located outside the storage chamber 72. The drive assembly 50 is drively connected to the dustproof component 30, and the drive assembly 50 can controllably (controlled by the user or other structure) drive the dustproof component 30 to reciprocate relative to the insertion port 14, thereby opening or closing one end of the dustproof component 30 at the insertion port 14.

[0037] Specifically, when one end of the dustproof component 30 is inserted into the insertion port 14, the insertion port 14 can be closed to prevent foreign objects or dust from the external environment from entering the aerosol generating device 100. When the dustproof component 30 is removed from the insertion port 14, the insertion port 14 can be opened so that the user can smoothly insert the aerosol generating matrix.

[0038] Since the dustproof component 30 is completely housed in the receiving cavity 12 of the main housing 10, it can prevent the dustproof component 30 from being easily damaged due to exposure, while improving the aesthetics of the aerosol generating device 100 and meeting the growing aesthetic needs of users.

[0039] The main housing 10 is generally hollow and cubic in shape to form the aforementioned receiving cavity 12. In the following embodiments, the length direction of the main housing 10 is the first direction (i.e., the X direction in FIG3), the width direction of the main housing 10 is the second direction (i.e., the Y direction in FIG3), and the height direction of the main housing 10 is the third direction (i.e., the Z direction in FIG3).

[0040] Furthermore, the main housing 10 includes a first housing 10a and a second housing 10b. The first housing 10a has a hollow shell-like structure and is open on one side in a first direction and at the third direction. The second housing 10b is inserted into the first housing 10a and closes the aforementioned openings. The first housing 10a and the second housing 10b together form a receiving cavity 12, and an insertion port 14 is opened at the third direction end of the second housing 10b.

[0041] Furthermore, the main housing 10 also has a control slot 16, and the drive assembly 50 partially protrudes from the control slot 16, so the user can control the movement of the dustproof component 30 through the drive assembly 50. Specifically, the insertion port 14 and the control slot 16 are opened in the second housing 10b and are located at one end of the main housing 10 in the third direction, and at opposite ends of the second housing 10b in the first direction.

[0042] The aerosol generating device 100 also includes a heating assembly 70 and a battery assembly 90. The heating assembly 70 is housed within a receiving cavity 12 and is located on the side of the main housing 10 with an insertion port 14 in a first direction. The heating assembly 70 forms a receiving chamber 72 with one open end, the open end of which faces and communicates with the insertion port 14. The battery assembly 90 is housed within the receiving cavity 12 and is located on the side of the main housing 10 with a control groove 16 in a first direction. The battery assembly 90 is electrically connected to the heating assembly 70, and the heating assembly 70 can heat the aerosol generating matrix in the atomizing heating chamber under the power of the electrical energy from the battery assembly 90.

[0043] The dustproof component 30 is generally rectangular in shape and is housed in the receiving cavity 12 at one end with an insertion port 14 in the third direction. Part of the second housing 10b covers the top of the dustproof component 30 and shields it. The length of the dustproof component 30 extends along a first direction, the width of the dustproof component 30 extends along a second direction, and the thickness of the dustproof component 30 extends along a third direction. Driven by the driving assembly 50, the dustproof component 30 reciprocates along the first direction, thereby opening or closing the insertion port 14 of the main housing 10.

[0044] Referring to Figures 2, 3, and 4, the drive assembly 50 is located on the side of the battery assembly 90 facing the control slot 16 in the third-order direction. The drive assembly 50 includes a control element 52 and a transmission unit 54. The control element 52 protrudes from the control slot 16, and the transmission unit 54 is housed within the receiving cavity 12. The control element 52 is connected to the dustproof component 30 via the transmission unit 54. Thus, the user can drive the transmission unit 54 through the control element 52 protruding from the control slot 16, thereby causing the dustproof component 30 to move back and forth.

[0045] In some specific embodiments, the control element 52 is a cylindrical toggle switch. The control element 52 is rotatably mounted on the main housing 10 via a mounting shaft, and the rotation axis of the control element 52 extends along a second direction. Part of the outer circular surface of the control element 52 is exposed outside the control groove 16, and the outer circular surface of the control element 52 has a concave-convex configuration, thereby providing greater friction to facilitate rotation by the user. In this way, the user can rotate the control element 52 by toggling it.

[0046] The transmission unit 54 is used to convert the rotation of the control member 52 into the reciprocating movement of the dustproof member 30. The transmission unit 54 includes a first transmission member 541, a second transmission member 543, and an intermediate transmission member 545. The first transmission member 541 is coupled to the control member 52 and rotates synchronously with the control member 52. The second transmission member 543 is drivenly connected to the dustproof member 30. The intermediate transmission member 545 is drivenly connected between the first transmission member 541 and the second transmission member 543. The first transmission member 541 and the intermediate transmission member 545 are arranged sequentially along the moving direction of the dustproof member 30 (i.e., the first direction). The dustproof member 30 is located on the side of the transmission unit away from the battery assembly 90 in the third direction.

[0047] In some further embodiments, the first transmission member 541 is a gear, which is fixed to one end of the control member 52 via a mounting shaft and coaxially arranged with the control member 52. Therefore, the rotation of the control member 52 can drive the first transmission member 541 to rotate synchronously. The intermediate transmission member 545 is a gear, which is rotatably disposed on the main housing 10 via a mounting shaft, and the rotation axis of the intermediate transmission member 545 extends along a second direction. The first transmission member 541 and the intermediate transmission member 545 mesh with each other, and the intermediate transmission member 545 can rotate synchronously under the drive of the first transmission member 541. The second transmission member 543 is a gear, which is rotatably disposed on the main housing 10 via a mounting shaft, and the rotation axis of the second transmission member 543 extends along a second direction. The second transmission member 543 and the intermediate transmission member 545 mesh with each other, and the second transmission member 543 can rotate synchronously under the drive of the intermediate transmission member 545.

[0048] Thus, when the user rotates the control component 52, the first transmission component 541, the intermediate transmission component 545, and the second transmission component 543 can be driven to rotate synchronously, thereby transmitting power to the dustproof component 30.

[0049] As shown in Figure 5, in some embodiments, the first transmission member 541 is a gear. The first transmission member 541 is fixed to one end of the control member 52 via a mounting shaft and is coaxially arranged with the control member 52. Therefore, the rotation of the control member 52 can drive the first transmission member 541 to rotate synchronously. The second transmission member 543 is a gear. The second transmission member 543 is rotatably arranged on the main housing 10 via a mounting shaft, and the rotation axis of the second transmission member 543 extends along a second direction. The intermediate transmission member 545 is a synchronous belt. The intermediate transmission member 545 is wound around the first transmission member 541 and the second transmission member 543. Therefore, the torque of the first transmission member 541 can be transmitted to the second transmission member 543 through the intermediate transmission member 545.

[0050] Please refer to Figures 2, 3, and 4. The surface of the dustproof component 30 facing the second transmission component 543 has a rack 32 that meshes with the second transmission component 543. The rack 32 extends from one end of the dustproof component 30 to the other end along the moving direction (i.e., the first direction). The second transmission component 543 meshes with the dustproof component 30. Thus, the rotation of the second transmission component 543 can be converted into linear movement of the dustproof component 30 through the gear and rack 32 engagement.

[0051] In some further embodiments, the second transmission member 543 includes a first transmission part 5432 and a second transmission part 5434 that are axially connected to each other. The first transmission part 5432 and the second transmission part 5434 are respectively provided with transmission teeth. The first transmission part 5432 is engaged or connected to the intermediate transmission member 545, and the second transmission part 5434 is engaged with the dustproof member 30.

[0052] The working principle of the above-mentioned aerosol generating device 100 is as follows:

[0053] When it is necessary to open the insertion port 14 to insert the aerosol generating substrate, the user can turn the outer surface of the control member 52 exposed in the control slot 16 to drive the control member 52 to rotate. The torque generated by the rotation of the control member 52 can be transmitted to the dustproof member 30 in sequence through the first transmission member 541, the intermediate transmission member 545, and the second transmission member 543. The dustproof member 30 moves towards the control member 52 in the first direction to disengage from the insertion port 14. Therefore, the user can insert the aerosol generating substrate into the heating component 70 through the insertion port 14 in the third direction.

[0054] When the insertion port 14 needs to be closed after use, the user can reverse the movement to expose the outer surface of the control member 52 in the operating slot, thereby causing the control member 52 to rotate in the opposite direction. The torque generated by the rotation of the control member 52 can be transmitted to the dustproof member 30 in sequence through the first transmission member 541, the intermediate transmission member 545, and the second transmission member 543. The dustproof member 30 moves away from the control member 52 along the first direction to extend into the insertion port 14. The insertion port 14 is sealed by the dustproof member 30, so it is difficult for dust and foreign objects in the external environment to enter the heating component 70, thereby ensuring the cleanliness of the inside of the aerosol generating device 100 and extending the service life of the aerosol generating device 100.

[0055] In the aforementioned aerosol generating device 100, the dustproof component 30 is completely housed within the receiving cavity 12 of the main housing 10, unlike the dustproof component 30 in the prior art which is at least partially exposed on the outer surface of the main housing 10. Therefore, while providing protection, it also has a high aesthetic appeal and can prevent the dustproof component 30 from being damaged due to exposure.

[0056] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
