Description

Technical Field

[0001] This application relates to the field of aerosol generating apparatus technology, and more specifically, to an aerosol generating apparatus. Background Technology

[0002] With the development of aerosol generating devices, existing single-compartment aerosol generating devices are gradually unable to meet the growing demand for diverse flavors from users. Therefore, multi-compartment aerosol generating devices have emerged on the market.

[0003] In a multi-compartment aerosol generating device, in order to allow users to inhale the aerosol generated by the aerosol generating medium in multiple compartments, for example, multiple heating elements and multiple compartments are set in the aerosol generating device. Each heating element heats the aerosol generating medium in one compartment separately. At the same time, a main air channel and multiple sub-air channels are also set. Each sub-air channel is connected to one compartment, and then all the sub-air channels are connected to the main air channel, which is used by the user for inhalation.

[0004] Existing aerosol generating devices typically require multiple air channels or air delivery pipes, resulting in high costs and low production efficiency due to assembly difficulties. In summary, existing aerosol generating devices suffer from high production costs and low efficiency. Utility Model Content

Furthermore, whenever a numerical range is referred to herein, it means including any referenced number (fraction or integer) within the referred range.

[0045] Please refer to Figures 1-5 The length direction of the atomizing tube 800 is the Z direction in the figure. This application provides an aerosol generating device, including:

[0046] The first container 100 and the second container 200 are respectively. The first container 100 stores a first liquid and the second container 200 stores a second liquid.

[0047] The atomizing tube 800 passes through the first receiving chamber 100 and the second receiving chamber 200, and has an air passage 810 inside. Along the length of the atomizing tube 800, the side wall of the atomizing tube 800 is provided with a first through hole 801 and a second through hole 802 that communicate with the air passage 810. The first through hole 801 is connected to the first receiving chamber 100, and the second through hole 802 is connected to the second receiving chamber 200.

[0048] The first heating element 300 is disposed in the air passage 810, located at one end where the first through hole 801 is located, and is used to heat the first liquid;

[0049] The second heating element 400 is disposed in the air passage 810 and located at one end where the second through hole 802 is located, and is used to heat the second liquid.

[0050] In this embodiment, since the first through hole 801 and the second through hole 802 are respectively connected to the first receiving chamber 100 and the second receiving chamber 200, when the user inhales, the first liquid and the second liquid in the first receiving chamber 100 and the second receiving chamber 200 will flow into the first through hole 801 and the second through hole 802 respectively; at this time, the first heating element 300 can heat the first liquid and the second heating element 400 can heat the second liquid, thereby generating two aerosols. The two aerosols will mix in the airway 810 and finally be inhaled by the user.

[0051] The aerosol generating device of this embodiment only requires an atomizing tube 800, a first heating element 300 and a second heating element 400 to process aerosol generating media in multiple chambers (at least the first receiving chamber 100 and the second receiving chamber 200). Therefore, the structure is simple and the production cost is low. At the same time, during assembly, it is only necessary to put the first heating element 300 and the second element into the atomizing tube 800, and then put the aerosol generating device into the aerosol generating device, and align the air passage 810 with the nozzle 20 to complete the assembly.

[0052] In summary, the aerosol generating device of this embodiment has low production cost and high production efficiency.

[0053] It should be understood that the first chamber can be composed of a first oil cup 31 and a first oil storage cotton 32, and the second chamber can be composed of a second oil cup 41 and a second oil storage cotton 42. If the aerosol generating device also includes multiple other chambers, such as a third chamber, a fourth chamber, etc., a third heating element, a fourth heating element, etc., can be installed in its air passage. Then, by setting through holes corresponding to the third chamber and the fourth chamber respectively on the side wall of the atomizing tube 800, the mixing of aerosols can be achieved.

[0054] Further, please refer to Figures 1-5 The aerosol generating device includes:

[0055] The first liquid suction member 500 is disposed in the air passage 810 and located at one end where the first through hole 801 is located, and is used to absorb the first liquid passing through the first through hole 801.

[0056] The second liquid suction member 600 is disposed in the air passage 810, located at one end where the second through hole 802 is located, and is used to absorb the second liquid passing through the second through hole 802.

[0057] In this embodiment, the first liquid absorber 500 can effectively absorb and store the first liquid, and the second liquid absorber 600 can effectively absorb and store the second liquid, thereby preventing the first liquid and the second liquid from mixing directly after entering the atomizing tube 800, thus avoiding affecting the taste of the final aerosol.

[0058] It should be understood that the liquid absorption rate and liquid permeation rate of the first liquid absorber 500 and the second liquid absorber 600 can be controlled by design, so that the liquid permeation rate is equal to the rate at which the first liquid and the second liquid pass through the first through hole 801 and the second through hole 802. At this time, it can effectively prevent the first liquid and the second liquid from entering the atomizing tube 800 too quickly, which would cause the first liquid absorber 500 and the second liquid absorber 600 to be unable to accommodate them, thereby preventing the first liquid and the second liquid from mixing.

[0059] Further, please refer to Figures 1-3 The first heating element 300 is located between the first liquid suction element 500 and the inner wall of the air passage 810, and the first heating element 300 and the air passage 810 are interference-fitted; and / or,

[0060] The second heating element 400 is located between the second liquid suction element 600 and the inner wall of the air passage 810, and the second heating element 400 is interference-fitted with the air passage 810.

[0061] In this embodiment, the outer wall of the first liquid-absorbing element 500 can abut against the inner wall of the air passage 810. At this time, the first heating element 300 located between the first liquid-absorbing element 500 and the air passage 810 will be in an interference fit with the air passage 810, thereby preventing the first heating element 300 from falling off. Similarly, the second heating element 400 can also be prevented from falling off by being in an interference fit with the air passage 810. Therefore, the aerosol generating device of this embodiment has strong stability and a long service life.

[0062] Further, please refer to Figures 1-4 The aerosol generating device also includes an insulating component 700, which is disposed between the first liquid-absorbing component 500 and the second liquid-absorbing component 600 to separate the first liquid-absorbing component 500 and the second liquid-absorbing component 600.

[0063] In this embodiment, the insulating component 700 can isolate the mutual influence of the current when the first heating component 300 and the second heating component 400 are energized, and can also prevent some of the first liquid from flowing to the second liquid absorption component 600 due to gravity, thereby improving the taste and service life of the aerosol generating medium produced by the aerosol generating device.

[0064] Further, please refer to Figures 1-3 The insulating component 700 is provided with a third through hole 720, which connects the first liquid-absorbing component 500 and the second liquid-absorbing component 600.

[0065] In this embodiment, the first heating element 300 heats the first liquid to generate the first aerosol, and the second heating element 400 heats the second liquid to generate the second aerosol. The third through hole 720 can reduce the flow area of ​​the external gas, the first aerosol and the second aerosol during flow, thereby increasing the percentage of the first aerosol and the second aerosol in the gas inhaled by the user, and thus improving the taste of the aerosol generated by the aerosol generating device.

[0066] Further, please refer to Figures 1-4 The aerosol generating device also includes a support member 900, which passes through the third through hole 720, the first liquid suction member 500, and the second liquid suction member 600, and is interference-fitted with both the first liquid suction member 500 and the second liquid suction member 600, and clearance-fitted with the third through hole 720.

[0067] In this embodiment, the support member 900 passes through the first liquid-absorbing member 500 and the second liquid-absorbing member 600 and is interference-fitted with the first liquid-absorbing member 500 and the second liquid-absorbing member 600. Therefore, it can be used to guide the first liquid-absorbing member 500 and the second liquid-absorbing member 600 during installation, thereby improving the assembly efficiency of the first liquid-absorbing member 500 and the second liquid-absorbing member 600.

[0068] Further, please refer to Figure 5 The side wall of the insulating component 700 is provided with a clearance groove 710, which is connected to the third through hole 720. Along the direction from the third through hole 720 to the outer side wall of the insulating component 700, the groove surface of the clearance groove 710 gradually increases.

[0069] In this embodiment, the groove surface of the clearance groove 710 should be understood as a plane parallel to the groove opening of the clearance groove 710. The clearance groove 710 enables the insulating component 700 to avoid the internal structure when it is installed into the atomizing tube 800, thereby improving the assembly efficiency of the insulating component 700.

[0070] Further, please refer to Figure 4 and Figure 5 The aerosol generating device also includes pins 50 and limiting gears 60. Along the length of the atomizing tube 800, pins 50 are connected in sequence to the second heating element 400 and the first heating element 300, and at least a portion of pins 50 extend beyond the atomizing tube 800.

[0071] The limiting gear 60 is interference-fitted in the air passage 810 and has a fourth through hole 61, through which the pin 50 passes.

[0072] In this embodiment, the limiting gear 60 can be stably connected to the air passage 810 through its own interference fit; at this time, since the pin 50 is located in the fourth through hole 61, the pin 50 can be effectively prevented from bending or falling out of the preset position, so as to improve the stability and service life of the single tube atomizing core structure.

[0073] Further, please refer to Figures 5-6 The resistance of the first heating element 300 is 0.5 ohms to 3 ohms; and / or,

[0074] The resistance of the second heating element 400 is 0.3 ohms to 1 ohm; and / or,

[0075] The first heating element 300 includes a first sub-heating element 310 and a second sub-heating element 320 arranged sequentially along the length of the atomizing tube 800; and / or,

[0076] The first heating element 300 is a heating wire with a mesh structure, which is fitted into the interior of the atomizing tube 800; and / or,

[0077] The second heating element 400 is a heating wire with a mesh structure, which is fitted to the inner wall of the atomizing tube 800.

[0078] In this embodiment, the resistance of the first heating element 300 and the resistance of the second heating element 400 allow them to be used in the containment chamber and ice chamber respectively, which contain the aerosol generating medium. The resistance of the first heating element 300 enables the first liquid in contact with it to generate aerosol more quickly, preventing excessive accumulation of the first liquid and its subsequent fall into the second suction element 600. When the first heating element 300 is a heating wire with a mesh structure, it effectively increases the contact area between the first liquid and itself, thereby improving the aerosol generation efficiency. When it adheres to the inner wall of the atomizing tube 800, it improves its stability and prevents shaking. Similarly, the second heating element 400 also improves its stability and aerosol generation efficiency. During the generation of the aerosol generating medium, one substance may be the main component, and another substance the minor component. To address the aforementioned needs, the capacity of the first containment chamber 100 can be set to be greater than that of the second containment chamber 200. Furthermore, the first heating element 300 includes a first sub-heating element 310 and a second sub-heating element 320. This allows the aerosol generation rate in the first containment chamber 100 to be greater than that in the second containment chamber 200, thereby enabling users to experience a distinct aerosol flavor profile.

[0079] Accordingly, please refer to Figures 1-2 This application also provides an aerosol generating device, which includes the aerosol generating device of any of the above embodiments.

[0080] In this embodiment, the aerosol generating device only requires an atomizing tube 800, a first heating element 300, and a second heating element 400 to process aerosol generating media in multiple chambers. Therefore, the structure is simple and the production cost is low. Furthermore, during assembly, it is only necessary to place the first heating element 300 and the second heating element into the atomizing tube 800, then place the aerosol generating device inside, and align the air passage 810 with the nozzle 20 to complete the assembly. In summary, the aerosol generating device of this embodiment has low production cost and high production efficiency.
