Description

Technical Field

[0001] This utility model relates to the field of novel tobacco technology, and more specifically, to an aerosol generation device based on a cartridge replacement method. Background Technology

[0002] Currently, most replaceable aerosol generators on the market use a fixed end face or cavity to connect the device to the cartridge, and in most cases, the heating element is in contact with the cartridge. Even in some non-contact aerosol generators, the distance between the heating element and the cartridge is very small to ensure effective use of the aerosol generating substrate. Furthermore, the heating cavity containing the aerosol generating substrate is designed close to the user's lips or nose. Therefore, the stacking design of the structural components for heating the aerosol generating substrate and the heating element has limitations, resulting in limited space utilization for the entire aerosol generator.

[0003] Therefore, there is an urgent need for an aerosol generation device based on a bomb-changing mechanism. Utility Model Content

[0004] The purpose of this invention is to provide an aerosol generation device based on a cartridge replacement method to solve the problems in the prior art. It can flexibly adjust the stacking structure according to the relevant space utilization requirements, improve space utilization, and eliminate the need for the traditional design of placing the heating chamber containing the aerosol generation substrate near the user's suction end.

[0005] This utility model provides an aerosol generating device based on cartridge replacement, comprising: a housing, a heating chamber disposed within the housing, an opening and closing part disposed on the housing at a corresponding position of the heating chamber, the heating chamber having an opening, a heating element disposed within the heating chamber, the heating chamber being used to accommodate and heat the cartridge, and one side of the housing being connected to the outside to form a suction port.

[0009] In the aerosol generating device based on cartridge replacement as described above, preferably, the cartridge pushing assembly includes a spring.

[0010] In the aerosol generating device based on the cartridge replacement method described above, preferably, a baffle is provided in the heating chamber near the receiving chamber.

It should also be understood that terms defined in a general dictionary, such as a dictionary, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and not as having an idealized or highly formalized meaning, unless expressly defined herein.

[0027] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0028] When a user inhales using an aerosol generator, one end of the cartridge interacts with the generator, while the other end typically contacts the user. Effective aerosol release and precise temperature control are crucial. For aerosol generators with the aforementioned structure, there are three main ways to reduce the aerosol inlet temperature using the cartridge: First, designing a cooling structure within the cartridge, such as increasing the aerosol's transport distance within the cartridge to facilitate heat transfer and dissipation from the outside environment, but this is limited by the cartridge's length. Second, adding cooling materials to the cartridge's components for heat absorption and cooling, but this is easily limited by cartridge cost. Third, utilizing the device's gas path structure to increase the proportion of externally drawn air in the aerosol, but this affects the aerosol's concentration and quality. Therefore, while controlling cost and aerosol quality, there is still room for optimization regarding the aerosol inlet temperature.

[0029] In addition, when the aerosol generating device heats the cartridge, part or all of the cartridge's volume will be exposed outside the device, posing a risk of the cartridge falling off or being damaged when the device is in operation.

[0030] Most aerosol generating devices on the market can only accommodate or heat a single cartridge at a time, and once a single cartridge is consumed, only one cartridge can be refilled manually at a time, resulting in low cartridge refilling efficiency.

[0031] like Figure 1 As shown, the aerosol generating device based on cartridge replacement provided in this embodiment includes the following: a housing 6, a heating chamber 3 is provided inside the housing 6, an opening and closing part (not shown) is provided on the housing 6 at the corresponding position of the heating chamber 3, the heating chamber 3 has an opening, a heating element (not shown) is provided inside the heating chamber 3, the heating chamber 3 is used to accommodate and heat the cartridge 10, and one side of the housing 6 is connected to the outside to form a suction port 8.

[0032] The housing 6 can accommodate other components of the aerosol generating device besides itself, and the main material of the cartridge 10 is an aerosol generating substrate. The heating element in the heating chamber 3 is used to heat the cartridge 10. The opening and closing part on the housing 6 facilitates the user to fill the cartridge 10.

[0033] Furthermore, the surface of the housing 6 has pores (not shown), and an airflow channel (not shown) is provided inside the housing 6. The pores communicate with the airflow channel, and the airflow channel is connected to the heating chamber 3. The suction port 8 is connected to the airflow channel, and the suction port 8 is connected to the heating chamber 3 through the airflow channel. It should be noted that the present invention does not specifically limit the structure of the airflow channel. The suction port 8 is used for the user to contact and inhale the aerosol. One end of the suction port 8 connected to the outside of the housing 6 is used to contact the user's senses, and the end away from the user is connected to the airflow channel inside the housing 6 for connection to the heating chamber 3.

[0034] In this invention, all components except the housing 6 can be flexibly stacked according to space utilization requirements, improving space efficiency. This eliminates the need for the heating chamber containing the aerosol-generating substrate to be positioned close to the user's inhalation end, as is common in current devices. Therefore, when designing the internal components of the aerosol-generating device, the distance between the heating chamber and the inhalation port can be flexibly set. This increases the aerosol's transmission process within the device's airflow, reducing the aerosol's inlet temperature. Furthermore, the cartridge structure and cost can be simplified according to product requirements.

[0035] Furthermore, a sensor assembly 5 is also provided within the housing 6. The sensor assembly 5 includes at least one of a temperature sensor and an infrared sensor. There may be one or more sensors, each disposed at various locations within the housing 6 to capture information. For example, a sensor disposed on the heating chamber 3 can detect whether a predetermined number of smoke cartridges 10 are present within the heating chamber 3.

[0036] Furthermore, a battery 1 is also provided inside the housing 6 to power the entire aerosol generating device.

[0037] Furthermore, the housing 6 is provided with a stimulation element. The stimulation element includes at least one of a light, a vibration motor, and a screen. When the sensor assembly 5 does not detect a specified number of cartridges 10, the stimulation element can prompt the user to replenish the cartridges.

[0038] Furthermore, a controller 2 is also provided inside the housing 6. The controller 2 is connected to the battery 1, the heating element in the heating chamber 3, the cartridge delivery assembly 7 in the receiving chamber 4, the sensor assembly 5, the stimulation element, and other components. The sensor assembly 5 transmits the captured information to the controller 2, and the controller 2 receives the data information from the sensor assembly 5 to control the working process of each component and regulate the operating status of each component of the device. In one embodiment of this utility model, the controller 2 is an MCU; the specific control principle and control process can be found in existing technology and will not be elaborated here.

[0039] like Figure 3 As shown, the overall working process is as follows: After the aerosol generating device is started, the sensor set on the heating chamber 3 detects whether there is a specified number of tobacco cartridges 10 in the heating chamber 3. If the specified number of tobacco cartridges 10 is not detected, the aerosol generating device prompts the user to replenish the tobacco cartridges through stimulation elements such as lights, vibration motors, and screen information, and then turns off the aerosol generating device; if the specified number of tobacco cartridges is detected, the controller controls the heating element in the heating chamber 3 to bake and heat the tobacco cartridges 10 to generate aerosol for the user to inhale.

[0040] Furthermore, such as Figure 2 As shown, in another embodiment of this utility model, the housing 6 is further provided with a receiving cavity 4 for accommodating a plurality of tobacco cartridges 10. Those skilled in the art will understand that the receiving cavity 4 can hold one or more tobacco cartridges 10. It should be noted that this utility model does not specifically limit the number or method of storing tobacco cartridges 10 in the receiving cavity 4. Correspondingly, the sensor assembly 5 can be disposed on the receiving cavity 4, and can detect whether a specified number of tobacco cartridges are present in the receiving cavity 4. If the specified number of tobacco cartridges are not detected, the aerosol generating device prompts the user to replenish the tobacco cartridges through stimulation elements, such as lights, vibration motors, screen information, etc.

[0041] Specifically, such as Figure 5 As shown, the receiving cavity 4 abuts against the heating cavity 3. The receiving cavity 4 is provided with a tobacco cartridge pushing assembly 7, which is used to push the tobacco cartridge 10 in the receiving cavity 4 into the heating cavity 3. The heating element in the heating cavity 3 is used to heat the tobacco cartridge 10 pushed into the heating cavity 3.

[0042] The cartridge pushing component 7 is a spring. It should be noted that the structure of the cartridge pushing component 7 is not specifically limited in this invention. The cartridges 10 in the receiving cavity 4 can be automatically pushed into the heating cavity 3 one by one or in parallel. It should be noted that the method of pushing the cartridges 10 in this invention is not specifically limited. In one embodiment of this invention, the cross-sectional area of ​​the receiving cavity 4 is larger than the cross-sectional area of ​​the heating cavity 3. Multiple receiving units are provided in the receiving cavity 4. The receiving cavity 4 can be rotated by a drive component to push the cartridges 10 in the receiving units opposite to the heating cavity 3 into the heating cavity 3 via the cartridge pushing component 7. In another embodiment of this invention, the cross-sectional area of ​​the receiving cavity 4 is approximately equal to the cross-sectional area of ​​the heating cavity 3. Multiple receiving units are provided in the receiving cavity 4. The cartridges 10 in all receiving units of the receiving cavity 4 are pushed into the heating cavity 3 one by one or in parallel via the corresponding cartridge pushing component 7.

[0043] Furthermore, a baffle 9 is provided inside the heating chamber 3 near the receiving chamber 4. The baffle 9 is a one-way baffle, used to restrict the tobacco cartridge 10 entering the heating chamber 3 from the receiving chamber 4 from being inside the heating chamber 3. When the tobacco cartridge 10 is pushed into the heating chamber 3, the baffle 9 can restrict the tobacco cartridge 10 from being inside the heating chamber 3 to a certain extent.

[0044] like Figure 4 As shown, the overall working process is as follows: After the aerosol generating device is started, the sensor installed on the receiving cavity 4 will pre-detect whether there is a specified number of tobacco cartridges in the receiving cavity 4. If the specified number of tobacco cartridges is not detected, the aerosol generating device will prompt the user to replenish the tobacco cartridges through stimulation elements such as lights, vibration motors, and screen information. If the specified number of tobacco cartridges is detected, the controller will control the tobacco cartridge pushing component 7 in the aerosol generating device to automatically push the specified number of tobacco cartridges one by one or in parallel into the heating cavity 3. When all the tobacco cartridges 10 are loaded into the heating cavity 3, the sensor installed in the heating cavity 3 will automatically detect whether the position of each tobacco cartridge 10 is compliant. If compliant, the controller will control the battery 1 to supply energy to the heating element in the heating cavity 3, so that the temperature of the heating element rises to a certain range, thereby baking and heating the tobacco cartridges 10 to generate aerosol. If not compliant, the aerosol generating device will prompt the user through stimulation elements such as lights, vibration motors, and screen information, and at the same time push the tobacco cartridges 10 back from the heating cavity 3 into the receiving cavity 4 and turn off the aerosol generating device.

[0045] The aerosol generating device based on cartridge replacement provided in this embodiment allows for flexible adjustment and stacking of all components except the housing, according to space utilization requirements, thus improving space utilization. It eliminates the need for the traditional design of placing the heating chamber containing the aerosol generating substrate close to the user's inhalation end. Therefore, when designing the internal components of the aerosol generating device, the distance between the heating chamber and the inhalation port can be flexibly set, thereby increasing the aerosol transmission process in the device's airway and reducing the aerosol inlet temperature. Furthermore, the cartridge structure and cost can be simplified according to product requirements. The heating chamber is located inside the housing, preventing cartridges from touching, falling, or being damaged when the device is in operation. It can simultaneously accommodate or heat multiple cartridges, and automatically refill one or more cartridges after they are consumed, greatly improving cartridge refilling efficiency.
