Description

Technical Field

[0001] The present invention relates to the technical field of aerosol generation, and more particularly, to an aerosol generating device. Background Art

[0002] Tobacco products (e.g., cigarettes, cigars, etc.) burn tobacco to produce tobacco smoke during use. Attempts have been made to replace these tobacco-burning products by creating products that release compounds without burning them. Examples of such products include electronic atomizers or heat-not-burn devices, which heat rather than burn materials to release active compounds to produce an aerosol for the user to inhale. An aerosol generator is a device that heats a cigarette, causing it to volatilize and produce an inhalable aerosol.

[0003] Aerosol generators are usually equipped with extractors, which can be pulled out to separate the cigarette from the heating element in the aerosol generator. A reasonable extractor structure can greatly improve the quality of the aerosol. The temperature of the heating element in current aerosol generators for baking cigarettes is generally over 200°C. When the extractor is pulled out after the puffing is completed, the high temperature on the extractor poses a risk of burns. Moreover, the accommodating cavity of most extractors is exposed through the mouth, and external dust, residue, etc. can easily fall into the accommodating cavity through the through hole, which can easily cause the accommodating cavity to be contaminated. In addition, the accommodating cavity is not breathable enough, and water vapor is easily generated inside. After accumulation, it will moisten the paper packaging material of the cigarette, causing damage to the paper packaging material, thereby affecting the user experience. Summary of the Invention

DETAILED DESCRIPTION

[0041] The drawings are for illustrative purposes only and should not be construed as limiting this patent. To better illustrate the embodiments, some components in the drawings may be omitted, enlarged, or reduced in size, and do not represent actual product dimensions. Those skilled in the art will understand that some well-known structures and their descriptions may be omitted from the drawings. The positional relationships depicted in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0042] Example 1

[0043] like Figure 1-5As shown, this embodiment provides an aerosol generating device comprising a main body 1 and an extractor 2 removably assembled within the main body 1. The main body 1 also comprises a support body 3 and a control panel 4. The support body 3 is assembled from left and right sides. A main body shell 5 is sheathed around the outer wall of the main body 1. The main body shell 5 conforms to the shape of the main body 1 and covers the entire sidewall of the main body 1. The forward projection of the main body shell 5 can be roughly rectangular, or can follow the main body 1 in a circular, polygonal, elliptical, betel nut-shaped, or other shape.

[0044] The extractor 2 is provided with a first receiving portion 7 for receiving a cigarette 6, and the main body 1 is provided with a second receiving portion 8. The first receiving portion 7 of the extractor 2 is completely accommodated in the second receiving portion 8. The top of the second receiving portion 8 has an insertion port for partially inserting the extractor 2, and the bottom of the second receiving portion 8 is arranged relative to the top.

[0045] The second receiving portion 8 is provided with a heating element 9, which is fixed to the bottom of the second receiving portion 8. One end of the heating element 9 is fixed to the bottom of the second receiving portion 8, and the other end is arranged in the second receiving portion 8 along the axial direction of the second receiving portion 8 and is located at the center of the second receiving portion 8. The heating element 9 is in the shape of a rod or a sheet, and its cross-section is circular, straight, polygonal, etc.

[0046] The heating element 9 can be a sensor capable of generating heat in a changing magnetic field. It is made of a magnetic material. When a changing magnetic field is applied to the magnetic material, energy loss occurs in the magnetic material due to eddy current loss and hysteresis loss. This lost energy is released from the magnetic material as heat. The greater the amplitude or frequency of the changing magnetic field applied to the magnetic material, the more heat energy can be released from the magnetic material.

[0047] like Figure 8 As shown, correspondingly, the side wall of the second receiving portion 8 is provided with an induction coil 10 capable of generating a changing magnetic field. The induction coil 10 is completely arranged around the periphery of the heating element 9 and is fixed to the wall of the second receiving portion 8. When the induction coil 10 is energized, an alternating magnetic field is generated around the second receiving portion 8, that is, the hollow area of ​​the induction coil 10 will generate an alternating magnetic field, and the heating element 9 generates heat under the action of the alternating magnetic field. A power supply component 11 electrically connected to the induction coil 10 is also provided in the main body 1. The frequency of the alternating current supplied to the induction coil 10 by the power supply component 11 is between 80KHz and 400KHz. More specifically, the frequency can be in the range of approximately 200KHz to 300KHz.

[0048] In some other embodiments, the heating element 9 can also generate heat through resistance. The power supply component 11 is electrically connected to the resistance of the heating element 9, and the DC supply voltage provided is in the range of about 2.5V to about 9.0V. The ampere of the DC current that can be provided by the power supply component 116 is in the range of about 2.5A to about 20A.

[0049] Specifically, the second housing portion 8 further includes a first sleeve 81 and a second sleeve 82. The first sleeve 81 surrounds the heating element 9, and the second sleeve 82 is sheathed around the outer wall of the first sleeve 81. The induction coil 10 is disposed between the first sleeve 81 and the second sleeve 82, maintaining a sealed state. The induction coil 10 is electrically connected to the power supply assembly 11 at both ends via the control board 4. When the power supply assembly 11 provides power, the induction coil 10 generates a changing magnetic field, which heats the heating element 9 in the second housing portion 8. Driven by the changing magnetic field, the induction current is generated, thereby heating the cigarette 6.

[0050] In order to position and fix the induction coil 10, a number of protrusions 811 are symmetrically provided on both sides of the outer wall of the first sleeve 81. Adjacent protrusions 811 are spaced a certain distance apart, and the induction coil 10 is fixed between the protrusions 811. By adjusting the spacing between the protrusions 811 at different positions, the coil density at different positions on the first sleeve 81 is changed to optimize the density of the magnetic flux lines at different positions inside the chamber. The induction coil 10 is arranged between the first sleeve 81 and the second sleeve 82, and the end of the second sleeve 82 is sealed and connected to the first sleeve 81 to prevent heat from dissipating through the gap between the connecting ends of the first sleeve 81 and the second sleeve 82. The second sleeve 82 is equivalent to a shielding cover, which concentrates the magnetic flux lines inside the heating chamber.

[0051] In order to be able to timely monitor the heating status of the heating component on the cigarette 6, a temperature measuring element 83 is arranged near the sensing element or the heating element. The temperature measuring element 83 monitors the surrounding temperature and feeds back the monitored temperature to the control module of the control board 4. The control module further controls the power supply to provide power to the magnetic induction coil 10 by comparing the preset temperature parameters with the real-time monitored temperature of the temperature measuring element 83, so that the heating component heats the cigarette 6 under the desired heating conditions.

[0052] The second receiving portion 8 and the power supply assembly 11 are both wrapped and fixed in the bracket body 3, and the control board 4 is connected to the power supply assembly 11. The power supply assembly 11 mainly includes a battery, which can be a rechargeable battery or a disposable battery, which is not limited here. The second receiving portion 8 and the power supply assembly 11 are arranged on opposite sides of the main body 1, and the second receiving portion 8 and the power supply assembly 11 are arranged side by side, such as Figure 1 shown.

[0053] The main body 1 also includes a baffle 12 for blocking the second receiving portion 8 and the control board 4. The two ends of the second receiving portion 8 are connected to the baffle 12, and the side walls of the baffle 12 are snap-fitted to the control board 4. A gap is left between the outer wall of the second sleeve 82 and the bracket body 3. The second receiving portion 8 is stably arranged inside the bracket body 3 by the baffle 12. At the same time, the heat generated by the second receiving portion 8 is difficult to diffuse to the control board 4 due to the obstruction of the baffle 12, further protecting the electronic components on the control board 4. When the aerosol generating device is activated by touch or pressing, a sensing chip is also provided on the control board 4. The control board 4 is further connected to a charging port 13, through which the user can charge the battery.

[0054] In addition, the main body 1 has an air intake channel connected to the first receiving portion 7. The air intake channel is below the second receiving portion 8 and extends downward along the axial direction of the second receiving portion 8. When smoking a cigarette 6, the outside air enters the first receiving portion 7 through the air intake channel from the bottom of the second receiving portion 8, and then enters the cigarette 6, forming an aerosol with the volatile substances generated by the cigarette 6 under the action of the heating element 9. The aerosol then enters the mouth through the mouthpiece. The air intake channel 13 is set below the second receiving portion 8 and extends downward along the axial direction of the first receiving portion 7 to ensure that the airflow in the air intake channel is roughly straight, thereby reducing the inhalation resistance. Figure 9-10 shown.

[0055] Specifically, the bottom of the second housing portion 8 is provided with a base 84 for fixing the heating element 9 and a connecting base 85 for supporting the base 84. The base 84 is provided with a fixing hole 841, through which the heating element 9 is fixed to the base 84, and the base 84 and the connecting base 85 are snap-connected. At the same time, the base 84 and the connecting base 85 are both provided with a plurality of ventilation holes 86. The ventilation holes 86 of the base 84 and the connecting base 85 are interconnected, allowing external air to enter the second housing portion 8 through the ventilation holes 86, which serve as an air intake channel.

[0056] When the user draws on the aerosol generating device, the outside air enters the second receiving portion 8 and the cigarette 6 through the air inlet channel. This is the first airflow path. The airflow in the first airflow path is the first airflow, which brings the aerosol generated by the volatilization of the cigarette 6 due to heat out of the aerosol generating device for the user to inhale.

[0057] At the same time, if Figure 6-7 As shown, the first receiving portion 7 is a hollow cylindrical structure with one end open, comprising a bottom wall and side walls. The end opposite the bottom wall is open, and a through hole 71 is located in the bottom wall. A cigarette 6 can be inserted into the first receiving portion 7, which is used to accommodate at least the tobacco segments within the cigarette 6. The mouthpiece of the cigarette 6 is located outside the first receiving portion 7 and can be held in the mouth. The aerosol generated by the volatilization of the tobacco within the cigarette 6 can be transferred to the mouth through the mouthpiece.

[0058] The first receiving portion 7 itself has a certain draft angle, and the diameter of the open end is larger than the diameter of the bottom, resulting in the sidewalls of the first receiving portion 7 extending from the open end to the bottom showing a slight inward indentation. This approach allows for a longer cigarette 6 to be inserted into the first receiving portion 7. Since the bottom end of the first receiving portion 7 has a smaller receiving space, it can fully contact the cigarette 6, thereby securely storing the cigarette 6 in the first receiving portion 7. Preferably, the bottom diameter of the first receiving portion 7 can be slightly larger than the diameter of the cigarette 6, so that the cigarette 6 can be inserted into the bottom of the first receiving portion 7.

[0059] In addition, the first receiving portion 7 can be at least partially received by the second receiving portion 8. The top of the first receiving portion 7 has a cigarette insertion port for inserting the cigarette 6. The bottom of the first receiving portion 7 is arranged opposite to the top. A through hole 71 is provided at the bottom of the first receiving portion 7. When the first receiving portion 7 is inserted into the preset position of the second receiving portion 8, the heating element 9 can pass through the through hole 71 and extend into the first receiving portion 7 to be inserted into the cigarette 6 in the first receiving portion 7, thereby heating the cigarette 6.

[0060] The extractor 2 is installed and matched with the bracket body 3. Specifically, the extractor 2 is a hollow structure, including an extractor shell 21. The first receiving part 7 is fixed in the extractor 2. A gap is left between the side wall of the extractor shell 21 and the first receiving part 7, so that there is a large thermal resistance between the first receiving part 7 and the extractor shell 21, so that when the first receiving part 7 has a high temperature, the extractor shell 21 can maintain a lower temperature within a safe range.

[0061] In one embodiment, the axial length of the extractor housing 21 can be greater than the axial length of the first receiving portion 7, so that the first receiving portion 7 is within the covering range of the extractor housing 21. After the first receiving portion 7 is extracted from the second receiving portion 8, the first receiving portion 7 is separated by the extractor housing 21, so that the first receiving portion 7 cannot directly contact other objects including human hands, thereby preventing the first receiving portion 7 from scalding human hands or other objects.

[0062] In one embodiment, the axial length of the extractor housing 21 may also be smaller than the axial length of the first receiving portion 7, so that part of the first receiving portion 7 protrudes from the covering range of the extractor housing 21. When the extractor 2 is assembled with the main body 1, the first receiving portion 7 contacts the main body 1 before the extractor housing 21, thereby facilitating the alignment of the insertion port of the first receiving portion 7 with the second receiving portion 8, thereby facilitating the accommodation of the first receiving portion 7 into the second receiving portion 8.

[0063] By moving the extractor 2 relative to the main body 1, the first receiving part 7 can be moved relative to the second receiving part 8, so that the first receiving part 7 can be away from the heating element 9 or close to the heating element 9. When the first receiving part 7 is close to the heating element 9, the first receiving part 7 goes deep into or deeper into the second receiving part 8, and the heating element 9 can extend into the first receiving part 7 through the through hole 71, and then be inserted into the cigarette 6 in the first receiving part 7 to heat the cigarette 6 from the center; when the first receiving part 7 is away from the heating element 9, at least part of the first receiving part can be withdrawn from the second receiving part 8, and the heating element 9 can be withdrawn from the first receiving part 7 through the through hole 71, and then separated from the cigarette 6. Due to the support and protection of the first receiving part 7 for the cigarette 6, the heating element 9 will not cause the cigarette 6 to break in the second receiving part 8 when it is separated from the cigarette 6, and the tobacco residue in the baked cigarette 6 is not easy to fall into the second receiving part 8, thereby keeping the second receiving part 8 clean.

[0064] The main body 1 is slidably connected to the extractor 2. Specifically, a guide rail 31 is provided on the side wall of the main body 1 that cooperates with it, that is, the guide rail 31 is located on the bracket body 3 on both sides, and the extension direction of the guide rail 31 is parallel to the axial direction of the first receiving portion 7. A guide block 211 is provided on the extractor housing 21, and the guide block 211 is slidably connected to the guide rail 31. The guide rail 31 guides the sliding direction of the extractor housing 21 relative to the main body 1 by guiding the guide block 211, so as to prevent the extractor 2 from deviating from the moving path during the extraction process, causing deformation of the first receiving portion 7 or the extractor housing 21. In a preferred embodiment, when the first receiving portion 7 is received in the second receiving portion 8, the side wall of the extractor housing 21 contacts the side wall surface of the main body 1, that is, when the extractor housing 21 moves relative to the main body 1, there is friction between the extractor housing 21 and the side wall of the main body 1, so as to increase the plug-in and pull-out force between the extractor 2 and the main body 1, and prevent the extractor 2 from accidentally detaching from the main body 1 under the action of external forces other than the extraction force.

[0065] To mitigate the water vapor generated by the aerosol generating device during use and prevent it from easily wetting the paper packaging material of the cigarette 6, the sidewall of the first receiving portion 7 is provided with a plurality of hollow holes 72, located near one end of the bottom wall. When a cigarette 6 is inserted into the first receiving portion 7, a certain gap exists between the outer surface of the cigarette 6 and the inner wall of the sidewall of the first receiving portion 7. When a user inhales from the aerosol generating device, after passing through the air inlet channel, at least a portion of the air will enter the gap between the outer surface of the cigarette 6 and the inner wall of the sidewall of the first receiving portion 7 through the hollow holes 72 of the first receiving portion 7. Through this gap, the air will escape the aerosol generating device along the outer surface of the cigarette 6. This constitutes the second airflow path, and the airflow in the second airflow path is the second airflow. During this escape process, the air will also carry away some of the water vapor surrounding the outer surface of the cigarette 6, effectively reducing the wetting of the outer surface of the cigarette 6 by the water vapor and effectively preventing damage to the paper packaging material of the cigarette 6 caused by the wetting of the water vapor.

[0066] The hollow hole 72 is positioned near the bottom sidewall of the first receiving portion 7. After entering the gap between the outer surface of the cigarette 6 and the inner sidewall of the first receiving portion 7 through the hollow hole 72, the outside air then escapes from the aerosol generating device along the entire length of the outer surface of the cigarette 6. Compared to a hollow hole positioned in the middle of the sidewall of the first receiving portion 7, this arrangement effectively increases the distance that the outside air flows along the outer surface of the cigarette 6, allowing for better removal of water vapor.

[0067] It is worth noting that, since the temperature of the second airflow is relatively low, while the temperature of the first airflow carrying the aerosol entering the cigarette 6 is relatively high, the second airflow can also lower the temperature of the outer surface of the cigarette 6 when flowing along the outer surface of the cigarette 6, thereby lowering the temperature of the first airflow, so that the temperature of the first airflow carrying the aerosol will not be too high when it escapes for the user to inhale.

[0068] Furthermore, in order to allow the second airflow to carry away more water vapor around the cigarette 6, in this embodiment, multiple hollow holes 72 are provided. Providing multiple hollow holes 72 allows, after outside air passes through the air inlet channel, more air to enter the gap between the outer surface of the cigarette 6 and the inner wall of the sidewall of the first receiving portion 7 through the hollow holes 72, thereby increasing the airflow of the second airflow compared to when there is only one hollow hole 72. The greater the airflow of the second airflow, the more water vapor it can carry away. Preferably, the multiple hollow holes 72 are uniformly arranged around the sidewall of the first receiving portion 7, or each through hole 71 in the multiple hollow holes 72 has the same aperture.

[0069] It should be understood that a single hollow hole 72 can be provided. It is sufficient to allow external air to enter the gap between the outer surface of the cigarette 6 and the inner wall of the sidewall of the first receiving portion 7 through the hollow hole 72. This embodiment does not limit the number of hollow holes 72 provided. Of course, providing only one hollow hole 72 is more effective in removing water vapor than providing multiple ventilation holes 86. It is easy to understand that the larger the area of ​​the hollow hole 72, the more external air can enter the single hollow hole 72, thereby increasing the airflow volume of the second airflow. In this embodiment, the hollow hole 72 is provided in an elongated strip shape along the axial direction of the first receiving portion 7. The elongated strip shape effectively increases the area of ​​the hollow hole 72.

[0070] The aerosol generating device of this embodiment, especially in the scenario where the overall size of the cigarette 6 is relatively long, will arrange the heating element 9 and the power supply component 11 in parallel to reduce the length of the aerosol generator. First, the extractor housing 21 is combined with the first receiving portion 7 of the extractor 2, so that when the extractor 2 is lifted, the extractor housing 21 can shield the first receiving portion 7, reducing the safety hazard caused by the high temperature of the first receiving portion 7. Secondly, the extractor housing 21 is used as the part to hold the extractor 2. Since the extractor housing 21 is part of the aerosol generating device and has a larger area, the user's extraction operation has more space, which is convenient for the user to disassemble the extractor 2. For example, the thumb can be used to press the top of the main body 1 to facilitate the extraction of the extractor 2 from the main body 1.

[0071] Furthermore, the extractor shell 21 and the main body shell 5 together form the shell of the aerosol generating device, corresponding to the parallel positional relationship of the heating element 9 and the power supply component 11. The extractor shell and the main body shell 5 are also arranged in parallel, which is beautiful as a whole and convenient for processing.

[0072] Example 2

[0073] This embodiment provides an aerosol generating device, which adds a cover 14 to the first embodiment. Specifically, the first receiving portion 7 and the second receiving portion 8 completely overlap during assembly, the opening of the extractor 2 is flush with the top surface of the bracket body 3, and the end surface of the bracket body 3 is provided with a cover 14 for covering the opening of the first receiving portion 7.

[0074] like Figure 11-12 As shown, the cover 14 is hinged to the top surface of the bracket body 3. The cover 14 rotates about the hinge axis and can cover the opening of the extractor 2 or be placed against the top surface of the bracket body 3. When the cover 14 covers the opening of the extractor 2, it is in the closed state; when the cover 14 is placed against the top surface of the bracket body 3, it is in the open state. The angle between the closed and open states is 180°, that is, when the cover 14 is rotated 180°, it can switch from the closed state to the open state, or from the open state to the closed state.

[0075] Alternatively, the cover 14 may be connected in a sliding manner to switch between the closed state and the open state.

[0076] In one embodiment, the cover 14 itself is made of a magnetic material, and magnets 15 are provided on the opening of the extractor 2 and the top surface of the bracket 3, which magnetically attract the cover 14. This magnetic attraction ensures that the cover 14 can be stably fixed in either the closed or open state. Typically, there are two magnets 15 in a single position, and they are symmetrically arranged.

[0077] In some other embodiments, the cover 14 is also fixed by snap fastening in the closed state or the open state.

[0078] In addition, a pressure switch 16 is provided on the top surface of the bracket body 3. This pressure switch 16 is connected to the control board 4 and is triggered when the cover body 14 is in contact with the top surface of the bracket body 3. The pressure switch 16 is a piezoelectric inductive switch or a piezoelectric inductive sensor. The contact surface between the pressure switch 16 and the top surface of the bracket body 3 is made of a piezoelectric material. When a force is applied to the piezoelectric material, its surface charge changes. This charge is amplified and converted into an electrical output proportional to the external force by the charge amplifier and measurement circuit, thereby triggering the pressure switch 16.

[0079] The cover 14 can be rotated from a closed position to an open position, or from an open position to a closed position. When the aerosol generating device is unloaded, or when no cigarette 6 is inserted into the aerosol generating device, the cover 14 can be rotated to a closed position. In the closed position, the cover 14 covers the opening of the extractor 2 to prevent foreign matter such as dust and debris from falling into the first receiving portion 7, thereby keeping the receiving chamber of the aerosol generating device clean when the aerosol generating device is unloaded.

[0080] When the cover 14 is fixed in the closed state by means of magnetism or snap fasteners, it can ensure that the cover 14 can remain in the closed state stably and stably cover the dust. When it is necessary to insert a cigarette 6 into the first receiving portion 7, the cover 14 can be moved from the closed state by rotating it, so that the cover 14 is transferred to the open state and remains in the open state. When the cover 14 is in the open state, it is facing the pressure in the open state, so the position of the cover 14 can be sensed by the pressure switch 16, or the pressure switch 16 can be triggered by the cover 14 touching the pressure switch 16 or by pressing the pressure on the cover 14, thereby starting the aerosol generating device. Each time the pressure switch 16 is triggered, the motor built into the aerosol generating device can vibrate or the signal light can flash, thereby having the feel or visual sensation of the switch being triggered, so as to improve the user experience. The motor is connected to the control board 4. Since the motor is a commonly used component, it will not be described in detail.

[0081] In order to prevent the aerosol generating device from being accidentally started, a protection mechanism is set through the control panel 4. When the pressure switch 16 is triggered continuously for a set number of times, or is triggered continuously for a set time, the heating element 9 in the aerosol generating device is activated to generate heat. Then, when the pressure switch 16 is triggered continuously for a set number of times, or is triggered continuously for a set time, the heating element 9 in the aerosol generating device is disconnected and stops generating heat.

[0082] Similarly, when the cover 14 is fixed in the open state by means of magnetism or snap fastening, it can ensure that the cover 14 can stay in the open state stably, avoiding displacement or shaking of the cover 14, thereby affecting the triggering of the pressure switch 16.

[0083] In addition, the two flip-up surfaces of the cover 14 are provided with raised patterns 811, which serve as indicators and help users identify the closed or open state. To facilitate relative rotation of the cover 14, the cover 14 is provided with a push portion 141. The push portion 141 can be touched by a finger, thereby being pushed by the finger, thereby pushing the cover 14 from the closed state to the open state, or from the open state to the closed state. The push portion 141 is located on the edge of the cover 14 and, to facilitate contact and force application by a finger, extends out of the main body 1 and is suspended in the air.

[0084] Example 3

[0085] This embodiment provides an aerosol generating device. This embodiment adds a waste hopper 17 and other components based on embodiment 1 or embodiment 2, and discloses a cleaning method, such as Figure 13-17 shown.

[0086] Since solid residue and oil droplets are generated during the heating process of cigarettes 6, particularly when a long cigarette 6 is placed in the aerosol generating device and the heating section is longer than the filtering section, a large amount of solid residue and oil droplets are generated during inhalation. To prevent the solid residue and oil droplets from diffusing within the aerosol generating device and thereby hindering aerosol generation, a waste hopper 17 is provided at the bottom of the connecting seat 85 of the second receiving portion 8. The discharge channel of the waste hopper 17 communicates with the air inlet channel, allowing the solid residue and oil droplets to be discharged to the exterior of the main body 1 through the waste hopper 17.

[0087] The ventilation holes 86 in the base 84 and the connecting base 85 are used for ventilation and to facilitate the introduction of liquid or solid residue from the second receiving portion 8 into the waste hopper 17. The ventilation holes 86 in the base 84 and the connecting base 85 are interconnected and arranged longitudinally opposite each other, allowing solid residue to flow smoothly into the waste hopper 17. The ventilation holes 86 are appropriately sized to ensure that solid residue or liquid from the second receiving portion 8 can flow smoothly into the collector while also ensuring sufficient support rigidity for the bottom wall of the connecting base 85.

[0088] The waste hopper 17 has sufficient capacity to store a sufficient amount of solid residue and liquid without causing liquid and smoke residue to enter other components of the aerosol generating device and affect its normal operation. In this embodiment, the waste hopper 17 is open at both ends. The connecting seat 85 is connected to the waste hopper 17. The specific connection method can be fixed or detachable. The waste hopper 17 is roughly funnel-shaped and includes a receiving portion 171 and a diversion portion 172.

[0089] The receiving portion 171 forms an open accommodating cavity, and at least a portion of the base 84 and the connecting seat 85 can be accommodated within the accommodating cavity, so that a stable connection is formed between the waste hopper 17 and the second accommodating portion 8, while the tobacco residue or tar inside the second accommodating portion 8 can all enter the interior of the waste hopper 17. The connecting seat 85 and the receiving portion 171 are mated and connected by a number of snaps. The inner diameter and outer diameter of the receiving portion 171 are larger than the inner diameter and outer diameter of the guide portion 172, and a boss is formed in the transition section between the receiving portion 171 and the guide portion 172. The bottom end of the connecting seat 85 abuts against the receiving portion 171 of the waste hopper 17, and the waste hopper 17 is fixed to the bracket body 3 via the boss.

[0090] A diversion structure is provided on the inner wall of the diversion portion 172, and the diversion structure can guide the smoke residue or liquid to the outlet of the waste hopper 17. The diversion structure includes a diversion slope, and the diversion slope has a sufficient inclination angle to cause the smoke residue or liquid to flow out after being subjected to sufficient gravity acceleration after contacting the diversion slope. For example, the angle between the diversion slope and the vertical axis is specified to be F, and the smaller the angle F, the larger the inclination angle of the diversion slope. In a preferred embodiment, the angle F is less than 45 degrees. In an optional embodiment, the diversion slope is a smooth slope, so that the smoke residue or liquid has less resistance during the downward movement.

[0091] In addition, the bottom surface of the main body shell 5 is provided with an end cover 18 for covering the outlet of the waste hopper 17. The end cover 18 is movably mounted on the bottom surface of the main body shell 5 and has a plurality of ventilation holes 181. When the heating element 9 is heating, external air can enter the heating position through the ventilation holes 181, the waste hopper 17, and the ventilation holes 86. This is the flow direction of the first airflow.

[0092] It is understandable that since the air holes 181 on the end cover 18 are mainly narrow strip holes and the size of the air holes 181 is relatively small, it is difficult for cigarette residue and tar to leak to the outside of the main body 1 through the air holes 181, and it will not cause leakage at the bottom of the aerosol generating device during the user's inhalation process.

[0093] When the user has smoked a certain number of cigarettes 6 or has used the aerosol generating device for a long time, the user can remove the end cover 18 so that the tobacco residue or tar collected in the waste hopper 17 can be discharged to the outside of the main body 1 through the outlet. At the same time, since the outlet of the waste hopper 17 is open, the user can remove the end cover 18 and insert a cleaning tool into the interior of the waste hopper 17 to effectively clean the tobacco residue or tar inside the waste hopper 17.

[0094] One side of the end cap 18 is snapped onto the main housing 5, while the other side is hinged to the bracket body 3 and is elastically reset by a torque spring. Pressing one side of the end cap 18 causes the other side of the end cap 18 to exert force on the torque spring. When the buckle on the end cap 18 separates from the main housing 5, the torque spring drives the end cap 18 upward, allowing the outlet of the waste hopper 17 to fully open.

[0095] Alternatively, the end cap 18 can be magnetically connected to the main housing 5. This allows the waste hopper 17 to be opened by removing the end cap 18. Alternatively, the main housing 5 can be provided with a sliding groove within which the end cap 18 slides. When waste needs to be discharged, the end cap 18 is slid to the other side.

[0096] Because the waste hopper 17 is disposed at the bottom end of the second receiving portion 8, the tobacco residue and tar generated within the second receiving portion 8 can be discharged to the exterior of the main body 1 through the waste hopper 17. This is particularly true when a long cigarette 6 is placed within the receiving portion of the aerosol generating device, for example, a cigarette 6 greater than 50 mm in length, or when the heating section of the cigarette 6 is longer than the filtering section. When a user smokes a cigarette 6, a large amount of tobacco residue and tar is generated. Over time, the accumulation of tar can potentially penetrate into the battery cavity and corrode electronic components. The waste hopper 17 allows for the timely discharge of tar.

[0097] This embodiment discloses an effective cleaning method for the device. The bottom end cover 18 of the aerosol generating device can be opened and closed, and the outlet of the waste hopper 17 is connected to the heating position. During the heating of the cigarette 6 in the receiving portion, the generated cigarette residue and tar will tend to gather or flow towards the waste hopper 17 due to gravity. The user can quickly discharge the cigarette residue or tar to the outside of the main body 1 through the outlet of the waste hopper 17.

[0098] After removing the end cap 18 from the open end of the first hole, the user can pass the cleaning tool into the main body 1 through the outlet of the waste hopper 17, thereby thoroughly cleaning the cigarette residue or tar in the second receiving portion 8. When the aerosol generating device is configured for use with a longer cigarette 6, the bottom of the cigarette 6 is closer to the second receiving portion 8 compared to the cigarette 6 insertion port of the second receiving portion 8, so cleaning from the bottom of the second receiving portion 8 is less difficult and more convenient for the user to perform cleaning operations. In addition, for some slender cigarettes 6, the cigarette 6 insertion port configured at the first end of the aerosol generating device is relatively small, and the user cannot perform cleaning operations. Therefore, the user can only remove the bracket body 3 and the main body shell 5 of the main body 1 before barely cleaning the heating position. In this embodiment, through the outlet of the waste hopper 17, the user can more easily perform cleaning operations, which greatly improves the user's operating experience.

[0099] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here.
