[0001] This application refers to Chinese Patent Application No. 202420187140.3, filed on January 24, 2024, entitled “Aerosol Generating Device”, which is incorporated herein by reference in its entirety. Technical Field

[0002] The present application relates to the field of atomization technology, and in particular to an aerosol generating device. Background Art

[0003] An aerosol is a colloidal dispersion system composed of small 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 is a device that converts a stored atomizable medium into an aerosol through heating or ultrasound. Atomizable media include liquids, gels, pastes, or solid aerosol-generating matrices. Atomizing these media delivers an inhalable aerosol to the user, replacing conventional product forms and absorption methods.

[0004] Some existing aerosol-generating devices have an insertion port for inserting a cylindrical aerosol-generating substrate. Users simply insert the cylindrical aerosol-generating substrate into the device for heating and use. However, to prevent dust and debris from entering the insertion port and maintain internal cleanliness, the insertion port must be sealed with a dust cover when the aerosol-generating substrate is not inserted. However, existing dust covers are often exposed to the exterior of the device, making them susceptible to damage and affecting the integrity and aesthetics of the aerosol-generating device. Summary of the Invention

[0005] In view of the above problems, the present application provides an aerosol generating device.

[0006] An aerosol generating device comprising:

[0007] A main shell is provided with a receiving cavity therein and an insertion port is opened on the main shell, the insertion port is communicated with the receiving cavity;

[0008] a dustproof member, movably accommodated in the accommodating cavity; and

[0009] The driving component is at least partially accommodated in the accommodating cavity and is in transmission connection with the dustproof piece. The driving component can controllably drive the dustproof piece to move back and forth so that one end of the dustproof piece opens or closes the insertion port.

[0010] When one end of the dust guard is inserted into the insertion port, it seals the port, preventing foreign matter and dust from the external environment from entering the aerosol generating device through the insertion port. When the dust guard is removed from the insertion port, the port is opened, allowing the user to smoothly insert the aerosol-generating substrate. Because the dust guard is completely contained within the accommodating cavity of the main housing, it is protected from damage due to exposure, while also improving the aesthetics of the aerosol generating device, meeting the growing aesthetic needs of users.

[0011] In one embodiment, the main shell is provided with a control slot, the control slot is spaced apart from the insertion port, and a portion of the driving assembly is exposed from the control slot.

[0012] Therefore, the user can control the movement of the dust-proof part through the driving assembly.

[0013] In one embodiment, the driving assembly includes a control member and a transmission unit, the control member is exposed in the control slot, the transmission unit is accommodated in the accommodating cavity, and the control member is connected to the dustproof member through the transmission unit.

[0014] In this way, the user can drive the transmission unit through the operating member exposed through the operating slot, thereby driving the dustproof member to move back and forth.

[0016] With this arrangement, part of the outer circumference of the operating member is exposed to the operating groove, and the outer circumference of the operating member is provided with a concave-convex arrangement, thereby having a large friction force to facilitate the user's rotation. In this way, the user can drive the operating member to rotate by turning the operating member.

[0017] In one embodiment, the transmission unit includes:

[0018] A first transmission member is connected to the operating member, and the first transmission member and the operating member rotate synchronously;

[0019] A second transmission member, transmission-connected to the dust-proof member; and

[0020] The intermediate transmission member is transmission-connected between the first transmission member and the second transmission member.

[0021] In this way, the user turns the operating member to rotate, which can drive the first transmission member, the intermediate transmission member, and the second transmission member to rotate synchronously in sequence, thereby transmitting power to the dustproof member.

[0022] In one embodiment, the first transmission member and the intermediate transmission member are arranged in sequence 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.

[0023] In this way, the user turns the operating member to rotate, which can drive the first transmission member, the intermediate transmission member, and the second transmission member to rotate synchronously in sequence, thereby transmitting power to the dustproof member.

[0024] In one embodiment, the intermediate transmission member and the second transmission member are rotatably disposed on the main housing, and the intermediate transmission member is engaged with the first transmission member and the second transmission member, respectively.

[0025] In this way, the user turns the operating member to rotate, which can drive the first transmission member, the intermediate transmission member, and the second transmission member to rotate synchronously in sequence, thereby transmitting power to the dustproof member.

[0026] In one embodiment, the second transmission member is rotatably disposed on the main housing, and the intermediate transmission member is wound around the first transmission member and the second transmission member.

[0027] With this arrangement, the torque of the first transmission member can be transmitted to the second transmission member through the intermediate transmission member.

[0028] In one embodiment, the second transmission member is rotatably disposed on the main housing, and the second transmission member is engaged with the dustproof member.

[0029] In this way, the user turns the operating member to rotate, which can drive the first transmission member, the intermediate transmission member, and the second transmission member to rotate synchronously in sequence, thereby transmitting power to the dustproof member.

[0030] In one embodiment, the second transmission member is a gear, and the dustproof member has a rack meshing with the second transmission member, and the rack extends along the moving direction of the dustproof member.

[0031] In this way, the rotation of the second transmission member can be converted into the linear movement of the dustproof member through the cooperation of the gear and rack.

[0047] Referring to FIG1 , one embodiment of the present application provides an aerosol generating device 100 for heating an aerosol generating substrate to generate an aerosol for use by a user. The heating method may be convection, conduction, radiation, or a combination thereof. The aerosol generating substrate is preferably a columnar solid. The aerosol generating substrate includes, but is not limited to, materials used for medical, health, wellness, and cosmetic purposes. For example, the aerosol generating substrate may be plant-based materials, such as plant roots, stems, leaves, flowers, buds, seeds, and the like.

[0048] Referring to Figures 1 to 3 , the aerosol generating device 100 includes a main housing 10, a dustproof member 30, and a drive assembly 50. The main housing 10 has a accommodating chamber 12 and a accommodating bin 72. The accommodating bin 72 is located within the accommodating chamber 12. An insertion port 14 is also provided at one end of the main housing 10. The insertion port 14 communicates with the accommodating bin 72, and an aerosol generating substrate can be inserted into the accommodating bin 72 through the insertion port 14. The dustproof member 30 is movably accommodated within the accommodating chamber 12 and is located outside the accommodating bin 72. At least a portion of the drive assembly 50 is accommodated within the accommodating chamber 12 and is located outside the accommodating bin 72. The drive assembly 50 is in transmission connection with the dustproof member 30. The drive assembly 50 can be controlled (by a user or other structure) to drive the dustproof member 30 to reciprocate relative to the insertion port 14, so that one end of the dustproof member 30 opens or closes the insertion port 14.

[0049] Specifically, when one end of the dustproof piece 30 extends into the insertion port 14, the insertion port 14 can be closed to prevent foreign matter or dust from the external environment from entering the interior of the aerosol generating device 100 through the insertion port 14. When the dustproof piece 30 is detached from the insertion port 14, the insertion port 14 can be opened to allow the user to smoothly insert the aerosol generating substrate.

[0050] Since the dustproof member 30 is completely accommodated in the accommodating cavity 12 of the main shell 10, the dustproof member 30 can be prevented from being easily damaged due to being exposed to the outside, while improving the aesthetics of the aerosol generating device 100 and meeting the user's growing aesthetic needs.

[0051] The main housing 10 is generally a hollow cubic structure to form the aforementioned accommodating chamber 12. In the following embodiments, the length direction of the main housing 10 is a first direction (i.e., the X direction in FIG. 3 ), the width direction of the main housing 10 is a second direction (i.e., the Y direction in FIG. 3 ), and the height direction of the main housing 10 is a third direction (i.e., the Z direction in FIG. 3 ).

[0052] The main housing 10 further comprises a first housing 10a and a second housing 10b. The first housing 10a is a hollow shell-like structure, with one side of the first housing 10a in the first direction and one end in the third direction being open. The second housing 10b is inserted into the first housing 10a and closes the aforementioned openings. The first and second housings 10a, 10b together form a receiving chamber 12, with an insertion port 14 located at one end of the second housing 10b in the third direction.

[0053] Furthermore, the main housing 10 is provided with a control slot 16 spaced apart from the insertion opening 14. A portion of the drive assembly 50 is exposed through the control slot 16, thereby allowing a user to control the movement of the dust guard 30 via the drive assembly 50. Specifically, the insertion opening 14 and the control slot 16 are provided 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.

[0054] The aerosol generating device 100 also includes a heating assembly 70 and a battery assembly 90. The heating assembly 70 is housed within the accommodating chamber 12. In a first orientation, the heating assembly 70 is located on the side of the main housing 10 where the insertion port 14 is located. One end of the heating assembly 70 forms an open accommodating chamber 72, with the open end of the accommodating chamber 72 facing the insertion port 14 and communicating with the insertion port 14. The battery assembly 90 is housed within the accommodating chamber 12. In a first orientation, the battery assembly 90 is located on the side of the main housing 10 where the control slot 16 is located. The battery assembly 90 is electrically connected to the heating assembly 70. The heating assembly 70 can heat the aerosol generating substrate in the atomizing heating chamber under the action of the electrical energy of the battery assembly 90.

[0055] The dust guard 30 has a generally rectangular sheet-like structure and is housed within the accommodating cavity 12. In the third direction, the dust guard 30 is located at the end where the insertion opening 14 is located. A portion of the second housing 10b covers and shields the dust guard 30. The dust guard 30 extends longitudinally along the first direction, widthwise along the second direction, and thicknesswise along the third direction. Driven by the drive assembly 50, the dust guard 30 reciprocates in the first direction, thereby opening and closing the insertion opening 14 of the main housing 10.

[0056] As shown in 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 direction. The drive assembly 50 includes a control member 52 and a transmission unit 54. The control member 52 is exposed from the control slot 16, and the transmission unit 54 is received in the accommodating cavity 12. The control member 52 is connected to the dustproof member 30 through the transmission unit 54. In this way, the user can drive the transmission unit 54 by using the control member 52 exposed from the control slot 16, thereby driving the dustproof member 30 to move back and forth.

[0057] Specifically, in some embodiments, the control member 52 is a cylindrical dial button. The control member 52 is rotatably mounted on the main housing 10 via a mounting shaft. The rotation axis of the control member 52 extends along the second direction. A portion of the outer circumference of the control member 52 is exposed to the control groove 16. The outer circumference of the control member 52 is provided with a concave and convex configuration, thereby providing a large friction force to facilitate rotation by the user. In this way, the user can rotate the control member 52 by dialing the control member 52.

[0058] The transmission unit 54 is used to convert the rotation of the operating member 52 into 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 connected to the operating member 52 and rotates synchronously with the operating member 52. The second transmission member 543 is transmission-connected to the dustproof member 30. The intermediate transmission member 545 is transmission-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 in sequence along the movement 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.

[0059] Furthermore, in some embodiments, the first transmission member 541 is a gear, fixedly coupled to one end of the control member 52 via a mounting shaft. The first transmission member 541 and the control member 52 are coaxially disposed, such that rotation of the control member 52 drives the first transmission member 541 to rotate synchronously. The intermediate transmission member 545 is a gear, rotatably disposed on the main housing 10 via a mounting shaft, with the rotation axis of the intermediate transmission member 545 extending along the second direction. The first transmission member 541 and the intermediate transmission member 545 are meshed with each other, and the intermediate transmission member 545 can rotate synchronously with the first transmission member 541. The second transmission member 543 is a gear, rotatably disposed on the main housing 10 via a mounting shaft, with the rotation axis of the second transmission member 543 extending along the second direction. The second transmission member 543 and the intermediate transmission member 545 are meshed with each other, and the second transmission member 543 can rotate synchronously with the intermediate transmission member 545.

[0060] In this way, when the user turns the operating member 52 to rotate, the first transmission member 541 , the intermediate transmission member 545 , and the second transmission member 543 can be driven to rotate synchronously in sequence, thereby transmitting power to the dustproof member 30 .

[0061] As shown in FIG5 , in some other embodiments, the first transmission member 541 is a gear. The first transmission member 541 is fixedly connected to one end of the operating member 52 via a mounting shaft and is coaxially arranged with the operating member 52. Therefore, rotation of the operating 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 mounted on the main housing 10 via a mounting shaft, and the rotation axis of the second transmission member 543 extends along the 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 via the intermediate transmission member 545.

[0062] Continuing with Figures 2, 3, and 4, the dust guard 30 has a rack 32 on one side facing the second transmission member 543. The rack 32 meshes with the second transmission member 543 and extends along the direction of movement of the dust guard 30 (i.e., the first direction). The rack 32 extends from one end of the dust guard 30 to the other end of the dust guard 30. The second transmission member 543 meshes with the dust guard 30. Thus, the rotation of the second transmission member 543 is converted into linear movement of the dust guard 30 through the cooperation of the rack and gear 32.

[0063] Further, in some embodiments, the second transmission member 543 includes a first transmission part 5432 and a second transmission part 5434, the first transmission part 5432 and the second transmission part 5434 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 transmission-connected with the intermediate transmission member 545, and the second transmission part 5434 is engaged with the dustproof part 30.

[0064] The working principle of the aerosol generating device 100 is as follows:

[0065] When it is necessary to open the insertion port 14 to insert the aerosol generating matrix, the user can turn the outer cylindrical surface of the operating member 52 exposed in the control groove 16 to drive the operating member 52 to rotate. The torque generated by the rotation of the operating member 52 can be transmitted to the dustproof member 30 through the first transmission member 541, the intermediate transmission member 545, and the second transmission member 543 in sequence. The dustproof member 30 moves toward the operating member 52 along the first direction to disengage from the insertion port 14. Therefore, the user can insert the aerosol generating matrix into the heating component 70 through the insertion port 14 along the third direction.

[0066] When the insertion port 14 needs to be closed after use, the user can reversely turn the outer cylindrical surface of the operating member 52 to expose the operating slot to drive the operating member 52 to rotate in the opposite direction. The torque generated by the rotation of the operating member 52 can be transmitted to the dustproof member 30 through the first transmission member 541, the intermediate transmission member 545, and the second transmission member 543 in sequence. The dustproof member 30 moves away from the operating member 52 in the first direction to extend into the insertion port 14. The insertion port 14 is closed by the dustproof member 30, so dust and foreign matter in the external environment are difficult to enter the heating component 70, thereby ensuring the cleanliness of the interior of the aerosol generating device 100 and extending the service life of the aerosol generating device 100.

[0067] In the above-mentioned aerosol generating device 100, the dustproof member 30 is completely accommodated in the accommodating cavity 12 of the main shell 10, which is different from the dustproof member 30 being at least partially exposed to the appearance surface of the main shell 10. Therefore, while playing a protective role, it has a high aesthetic value and can prevent the dustproof member 30 from being damaged due to exposure to the outside.

[0068] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above 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.

[0069] The above embodiments merely illustrate several implementation methods of the present application. 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 a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
