Description

Technical Field

[0001] This application relates to the field of aerosol generating device technology, and more specifically, to an aerosol generating device and a method for replacing the atomizing core. Background Technology

[0002] The working principle of an aerosol generating device is as follows: When the user draws air through the suction channel of the nozzle, the air pressure inside the atomizing core drops instantly. Since the interior of the atomizing core is connected to the liquid storage chamber, the aerosol generating medium is driven by the pressure difference between the liquid storage chamber and the interior of the atomizing core to enter the interior of the atomizing core from the liquid storage chamber, and then heated and atomized by the atomizing core to generate aerosol. An aerosol generating device generally includes a main body, which has a liquid storage chamber and an atomizing core inside the liquid storage chamber.

[0003] When there is still aerosol generating medium in the reservoir, if the atomizing core is found to be damaged or its heating power reduced, a new atomizing core needs to be replaced. The traditional replacement method is to first disconnect the atomizing core assembly from the main body through the limiting component, and then pull the atomizing core out from the bottom of the main body to replace and assemble the new atomizing core. The new atomizing core needs to be rotated and tested to align with the original limiting component before assembly can be completed, so the operation is complicated. In addition, the existing technology is prone to being accidentally pulled out of the reservoir by children or other people when there is still aerosol generating medium in the reservoir, causing the aerosol generating medium in the reservoir to leak out and cause pollution.

[0004] In summary, the replacement method of the atomizing core in the existing aerosol generating device is complicated and prone to leakage during the replacement process. Summary of the Invention

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0022] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] To solve the above technical problems, please refer to Figures 1 to 8 This application provides an aerosol generating device 10, comprising: The main body 100 has a liquid storage chamber inside, and includes a first housing 140 and a second housing 150 that are detachably connected. The first housing 140 is provided with a suction channel 110. The atomizing core assembly 300 is located in the liquid storage chamber and includes an atomizing core 310 and an atomizing tube 320. The atomizing tube 320 is provided with a second liquid guiding hole 321 that communicates with the atomizing core 310. The atomizing tube 320 divides the liquid storage chamber into a first sub-liquid storage chamber 120 and a second sub-liquid storage chamber. The second sub-liquid storage chamber is connected to the suction channel 110. The atomizing core 310 is located in the second sub-liquid storage chamber and is connected to the first housing 140. Sleeve 200 is disposed in the first sub-liquid storage chamber 120 and sleeved on the atomizing tube 320. The side wall of sleeve 200 is provided with a first liquid guiding hole 210. The driving component 400 is used to drive the sleeve 200 to rotate relative to the atomizing core assembly 300 so that the first liquid guide hole 210 and the second liquid guide hole 321 are connected or separated.

[0024] In this embodiment, the process of disassembling the atomizing core 310 from the aerosol generating device 10 is as follows: First, the drive unit 400 is controlled to operate, causing the drive unit 400 to drive the sleeve 200 to rotate relative to the atomizing tube 320 around the Z-axis until the first liquid guiding hole 210 and the second liquid guiding hole 321 are in a disjoint state. At this time, the first liquid guiding hole 210 abuts against the outer wall of the atomizing tube 320, and the aerosol generating medium cannot enter the atomizing tube 320 to contact the atomizing core 310; Second, by moving the first housing 140 along the Z-axis direction, the atomizing core 310 moves with the first housing 140. Disconnect the atomizing tube 320; then replace the atomizing core 310 on the first housing 140; then reconnect the first housing 140 to the second housing 150 so that the atomizing core 310 is inserted into the atomizing tube 320; finally, control the drive unit 400 again to make the first liquid guide hole 210 and the second liquid guide hole 321 connected, so that the aerosol generating medium can pass through the first liquid guide hole 210 and the second liquid guide hole 321 to contact the atomizing core 310, and then the atomizing core 310 heats the aerosol generating medium to produce aerosol, which the user can draw in through the suction channel 110.

[0025] In summary, in this embodiment, the atomizing core 310 can be extracted through the separation action of the first housing 140 and the second housing 150. When it is replaced and reinstalled, it is only necessary to align and connect the first housing 140 and the second housing 150 to ensure that the atomizing core 310 is inserted into the atomizing tube 320. Therefore, the operation is simple. Furthermore, the atomizing core 310 is still in contact with the aerosol generating medium during the extraction process, thereby avoiding leakage of the aerosol generating medium.

[0026] It should be understood that the atomizing tube 320 can be fixedly connected to the main body 100 so that it remains stationary relative to the Z-axis while the sleeve 200 moves; the atomizing tube 320 can also be connected to the sleeve 200, but in this case the coefficient of friction between the atomizing tube 320 and the sleeve 200 is smaller. For example, by setting a support spanning the inner wall inside the atomizing tube 320, and then setting a rotating shaft on the support, the atomizing tube 320 is rotatably connected to the rotating shaft, and the connection between the rotating shaft and the atomizing tube 320 is achieved by means of roller friction, ball friction, etc.

[0027] Further, please refer to Figures 4-5The inner wall of the first housing 140 is provided with a first protrusion 111 and a first sealing member 500. The suction channel 110 is provided on the first protrusion 111. The first sealing member 500 is sleeved on the first protrusion 111 and is provided with a first through hole. The outer wall of the atomizing core 310 is provided with a first buckle 311. The first buckle 311 passes through the first through hole and abuts against the side of the first sealing member 500 away from the second housing 150, for connecting the atomizing core 310 and the first housing 140.

[0028] In this embodiment, firstly, the cooperation of the first sealing element 500 and the first buckle 311 achieves a reliable connection between the atomizing core 310 and the first housing 140, ensuring the sealing of the connection between the atomizing core 310 and the first housing 140 and preventing leakage of aerosol generation medium; secondly, the first sealing element 500 is sleeved on the first protrusion 111, further enhancing the sealing effect of the suction channel 110 and preventing aerosol generation medium from seeping out from the connection.

[0029] Further, please refer to Figures 4-5 The first sealing element 500 has a first groove on the side facing the second housing 150, and a first through hole is provided at the bottom of the first groove. The end of the atomizing tube 320 facing the first housing 140 abuts against the bottom of the first groove, and the side wall of the atomizing tube 320 abuts against the side wall of the first groove.

[0030] In this embodiment, firstly, the first groove can guide the atomizing tube 320 to abut against the first housing 140; secondly, the first groove can also restrict the movement of the atomizing tube 320 and improve the sealing between the atomizing tube 320 and the first housing 140.

[0031] For further details, please refer to... Figures 4-5 The first through hole is an annular hole, and the first buckle 311 is an annular protrusion, which is located on the outer wall of the atomizing core 310.

[0032] In this embodiment, firstly, the fit between the annular hole and the annular protrusion provides a uniform contact surface, enhancing the stability of the connection and the continuity of the seal, and preventing local leakage; secondly, the annular structure avoids stress concentration that may be caused by point contact, extending the service life of the component; and thirdly, this symmetrical design simplifies the installation process, allowing users to correctly install the atomizing core 310 without a specific orientation, thus improving assembly accuracy.

[0033] Further, please refer to Figures 4-8The aerosol generating device 10 also includes a second sealing element 600, which is located inside the main body 100 on the side near the second housing 150. The second sealing element 600, the second housing 150, and the first housing 140 together define a liquid storage cavity. The second sealing element 600 is provided with a second through hole. The sleeve 200 is provided with a second buckle at the end facing the second housing 150. The second buckle passes through the second through hole and abuts against the side of the second sealing element 600 away from the first housing 140, for connecting the sleeve 200 and the second sealing element 600.

[0034] In this embodiment, firstly, the second sealing member 600, together with the second housing 150 and the first housing 140, forms a liquid storage cavity, ensuring the sealing of the liquid storage cavity and effectively preventing the aerosol-generating medium from leaking into other components inside the second housing 150 (such as batteries, circuit boards, drive components 400, etc.); secondly, the sleeve 200 is connected to the second sealing member 600 through the second buckle, so that the position of the sleeve 200 is fixed, avoiding displacement during use.

[0035] It should be understood that, such as Figures 4-5 As shown, the second buckle can be integrally formed with the engaging tooth 220, that is, the engaging tooth abuts against the first sealing member 600.

[0036] Further, please refer to Figure 1 , Figures 4-8 The driving component 400 includes a motor 410 and a gear 420 connected to each other. The outer wall of the sleeve 200 is provided with meshing teeth 220, which mesh with the gear 420. The motor 410 is used to drive the gear 420 to rotate, so as to drive the sleeve 200 to rotate relative to the atomizing core assembly 300.

[0037] In this embodiment, firstly, the driving mechanism of the motor 410 and gear 420 achieves precise control of the rotation of the sleeve 200, ensuring that the first liquid guide hole 210 and the second liquid guide hole 321 can be accurately connected or separated; secondly, the meshing transmission efficiency of the gear 420 and the meshing teeth 220 is high, the operation is smooth, and noise and wear are reduced; then, the entire drive component 400 has a compact structure, which is easy to integrate into the aerosol generating device 10, thus optimizing the overall layout of the device.

[0038] Further, please refer to Figure 1 , Figures 4-8 The drive member 400 is connected to the outer side wall of the sleeve 200, and at least a portion of the drive member 400 extends to the outside of the main body 100 to form a toggle part (not shown in the figure), which is used to toggle to drive the sleeve 200 to rotate relative to the atomizing core assembly 300.

[0039] In this embodiment, when the actuating part extends to the outside of the main body 100, the user can conveniently and quickly adjust the aerosol production rate according to actual needs by actuating the actuating part; at the same time, the aerosol production rate can continue to be adjusted even when the aerosol generating device is out of power.

[0040] Further, please refer to Figure 1 , Figures 4-8 The driving component 400 includes a first magnetic attraction component (not shown in the figure) and a motion track (not shown in the figure). The motion track is arranged around the outer side wall of the sleeve 200. The outer side wall of the sleeve 200 is provided with a second magnetic attraction component (not shown in the figure). The first magnetic attraction component is used to move around the motion track so as to drive the sleeve 200 to rotate relative to the atomizing core assembly 300 through the magnetic connection between it and the second magnetic attraction component.

[0041] In this embodiment, the first magnetic attractor and the second magnetic attractor are connected by magnetism, which can effectively avoid contact wear between the two, thereby improving the service life of the aerosol generating device 10.

[0042] Further, please refer to Figure 1 , Figures 4-8 The aerosol generating device 10 also includes a third sealing element 700, which is connected to the end of the sleeve 200 away from the first housing 140 to seal the second sub-liquid storage chamber. An electrode 800 is provided on the side of the third sealing element 700 facing the first housing 140, and the electrode 800 is connected to the atomizing core assembly 300.

[0043] In this embodiment, firstly, the third seal 700 can effectively seal the second sub-liquid storage chamber, preventing the aerosol generation medium from leaking from the bottom of the sleeve 200; secondly, the electrode 800 is integrated on the third seal 700, making the electrical connection of the atomizing core assembly 300 more convenient and reliable.

[0044] Further, please refer to Figure 1 , Figures 4-8 The aerosol generating medium also includes an elastic liquid-absorbing element, which is disposed in the second sub-liquid storage chamber, and the electrode 800 is inserted through the elastic liquid-absorbing element.

[0045] In this embodiment, firstly, the elastic liquid-absorbing element can absorb and store the aerosol generating medium, providing a continuous and stable liquid supply to the atomizing core 310; secondly, the electrode 800 is inserted into the elastic liquid-absorbing element, fixing its position, while the elastic material protects the electrode 800; thirdly, the buffering characteristics of the elastic liquid-absorbing element reduce the impact of vibration on the electrode 800 during device use, improving its service life. It should be understood that the elastic liquid-absorbing element includes absorbent cotton, polyurethane foam, elastic resin, etc.

[0046] Further, please refer to Figure 1 , Figures 4-8 The second housing 150 has a transparent area on its side wall, and the orthographic projection of the sleeve 200 onto the side wall is located within this transparent area. When the first liquid guide hole 210 is connected to the second liquid guide hole 321, the first liquid guide hole 210 is located within the transparent area; and / or, The aerosol generating device 10 is equipped with an indicator light that changes color when the first liquid guide hole 210 and the second liquid guide hole 321 are connected or staggered; and / or, The aerosol generating device 10 is equipped with a display screen. When the first liquid guide hole 210 and the second liquid guide hole 321 are connected or intersected, the display screen shows a prompt message; and / or, The aerosol generating device 10 is equipped with an audio system. When the first liquid guide hole 210 and the second liquid guide hole 321 are connected or intersected, the audio system plays a prompt tone.

[0047] In this embodiment, firstly, the transparent area on the second housing 150 allows the user to visually see the position of the sleeve 200 and the liquid guide hole, making it convenient to check whether the liquid guide hole is aligned; secondly, indicator lights, displays, or audio prompts provide prompts when the liquid guide holes are connected or misaligned, enhancing the user's interactive experience; and thirdly, these designs improve the operability and safety of the device, ensuring that the user uses it correctly and avoiding misoperation.

[0048] Further, please refer to Figure 1 , Figures 4-8 The conductive area of ​​the first liquid guiding hole 210 is smaller than that of the second liquid guiding hole 321; and / or, The outer side wall of the sleeve 200 is provided with a third buckle, and the inner side wall of the first housing 140 is provided with a fourth buckle. When the first liquid guide hole 210 is connected to the second liquid guide hole 321, the orthographic projection of the third buckle and the orthographic projection of the fourth buckle at least partially intersect along the direction from the first housing 140 to the second housing 150. The third buckle and the fourth buckle are used to engage with each other to restrict the first housing 140 and the second housing 150 from separating.

[0049] In this embodiment, firstly, the conduction area of ​​the first liquid guide hole 210 is smaller than that of the second liquid guide hole 321, so that the liquid flow rate is controlled and the atomizing core 310 is prevented from being over-supplied with liquid; secondly, the third and fourth latches engage with each other when the liquid guide holes are open, ensuring a stable connection between the first housing 140 and the second housing 150, and preventing the atomizing core 310 from being accidentally pulled out when the aerosol generating medium can enter the atomizing core 310.

[0050] Accordingly, please refer to Figures 4-9 This application also provides a method for replacing an atomizer core, which is applied to the aerosol generating device 10 of any of the above embodiments, and includes: S100, the sleeve 200 is rotated by the driving component 400 until the first liquid guide hole 210 and the second liquid guide hole 321 are separated; S200, the first housing 140 and the second housing 150 are separated so as to drive the atomizing core 310 out of the atomizing tube 320; S300, disassemble and replace the atomizer core 310 connected to the first housing 140; S400, the first housing 140 and the second housing 150 are connected, and the replaced atomizing core 310 is located inside the atomizing tube 320.

[0051] In this embodiment, as summarized above, the atomizer core replacement method can extract the atomizer core 310 through the separation action of the first housing 140 and the second housing 150. When reinstalling after replacement, it is only necessary to align and connect the first housing 140 and the second housing 150 to ensure that the atomizer core 310 is inserted into the atomizing tube 320. Therefore, the operation is simple. Furthermore, the atomizer core 310 still comes into contact with the aerosol generation medium during the extraction process, thereby avoiding leakage of the aerosol generation medium.

The driving element 400 includes a motor 410 and a gear 420 connected to each other. The outer wall of the sleeve 200 is provided with meshing teeth 220, which mesh with the gear 420. The motor 410 is used to drive the gear 420 to rotate, thereby driving the sleeve 200 to rotate relative to the atomizing core assembly 300. The step of driving the sleeve 200 to rotate through the driving element 400 until the first liquid guiding hole 210 and the second liquid guiding hole 321 are separated includes: The motor 410 drives the gear 420 to rotate, so that the power is transmitted to the meshing teeth 220 through the gear 420, causing the sleeve 200 to rotate. The sleeve 200 is rotated by the motor 410 to the prompting element to issue a prompt. Stop motor 410 from rotating.

[0053] In this embodiment, firstly, the prompting device can clearly indicate the conduction status of the first liquid guide hole 210 and the second liquid guide hole 321, helping the user to make an accurate judgment; secondly, the motor 410 drives the sleeve 200 to rotate until the prompting device issues a prompt, realizing automatic positioning and improving the convenience and accuracy of operation; then, this automated prompting mechanism reduces the difficulty of user operation, improves the user experience, and ensures that the device works in the correct state.
