[0050] The present application will be further described below in conjunction with specific embodiments and the accompanying drawings.

[0051] Please refer to Figures 1 to 4 , the first embodiment of the present application provides an aerosol generating device 10 for heating an aerosol generating substrate to atomize and generate an aerosol for user use, aiming to effectively solve the problem of liquid leakage caused by using an additional liquid storage member for liquid supply.

[0052] The aerosol generating device 10 includes a main body 1, a second liquid storage member 5, an elastic member 50 and a plugging member 6. The main body 1 includes a housing (not shown in the figure) and a first liquid storage member 20. The housing is provided with a receiving cavity 100 and a guiding cavity 101. The first liquid storage member 20 is received in the receiving cavity 100, and the first liquid storage member 20 is provided with a liquid guiding hole 41. The second liquid storage member 5 is detachably installed in the guiding cavity 101, which is convenient for installation.

[0053] The second liquid storage member 5 is provided with a plugging portion 51, which can be inserted into the liquid guiding hole 41, so as to realize the conduction between the second liquid storage member 5 and the first liquid storage member 20, ensuring that the second liquid storage member 5 can supplement the liquid aerosol generating substrate for the first liquid storage member 20. At the same time, the second liquid storage member 5 can slide relative to the first liquid storage member 20 along the extending direction of the plugging portion 51 (i.e., the extending direction of the liquid guiding hole 41), so as to facilitate the disassembly and installation of the second liquid storage member 5.

[0054] The elastic member 50 is clamped between the first liquid storage member 20 and the second liquid storage member 5, playing a role of buffering and resetting. A plugging member 6 is arranged at the position of the liquid guiding hole 41. The plugging member 6 has the function of plugging the liquid guiding hole 41. The special design of the plugging member 6 realizes the switching between the isolation and conduction between the first liquid storage member 20 and the second liquid storage member 5. Specifically, when the second liquid storage member 5 approaches the first liquid storage member 20 and compresses the elastic member 50, the plugging member 6 will automatically avoid the liquid guiding hole 41, so that the second liquid storage member 5 is smoothly conducted with the first liquid storage member 20, ensuring that the aerosol generating substrate in the second liquid storage member 5 can be normally transported to the first liquid storage member 20 through the plugging portion 51 and the liquid guiding hole 41.

[0055] It can be understood that under the reset action of the elastic member 50, when the second liquid storage member 5 moves away from the first liquid storage member 20, the plugging member 6 will quickly plug the liquid guiding hole 41, isolating the second liquid storage member 5 from the first liquid storage member 20, so that the liquid aerosol generating substrate in the second liquid storage member 5 cannot flow out, effectively preventing the leakage of the aerosol generating substrate and solving the problem of liquid leakage caused by using an additional liquid storage member for liquid supply.

[0056] In daily use, when the user needs to add liquid aerosol generating matrix to the first liquid storage part 20, the user only needs to invert the aerosol generating device 10, press the first liquid storage part 20, so that the elastic part 50 is compressed, and the blocking part 6 avoids the liquid guide hole 41, so that the liquid guide hole 41 is connected to the second liquid storage part 5, so that the aerosol generating matrix in the second liquid storage part 5 flows to the first liquid storage part 20 under the action of gravity, and provides the first liquid storage part 20 with liquid aerosol generating matrix (hereinafter referred to as "liquid supply"), which is convenient to operate. When the liquid supply is completed, the user releases the pressing action on the second liquid storage part 5, and the second liquid storage part 5 moves to the blocking part 6 under the action of the reset elastic force of the elastic part 50 to form a blockage on the liquid guide hole 41, so as to isolate the second liquid storage part 5 from the first liquid storage part 20, and prevent the second liquid storage part 5 from continuously supplying liquid and causing leakage, thereby improving the reliability of the aerosol generating device 10 and improving the user experience.

[0057] This design can prevent the user from habitually pressing during normal inhalation, causing the aerosol-generating matrix in the second liquid storage member 5 to continue to flow to the first liquid storage member 20 and cause leakage. The bottom of the second liquid storage member 5 can be arranged to be flush with the bottom surface of the shell under the elastic force of the elastic member 50, thereby ensuring the flatness of the entire aerosol generating device 10 and improving its appearance.

[0058] In one embodiment, the second liquid storage member 5 further includes a bottle body 53 and a bottom plug 54 mounted on the lower opening of the bottle body 53, and the plug-in portion 51 is disposed at one end of the bottle body 53 away from the bottom plug 54. With such a design, the second liquid storage member 5 can be filled with liquid without being separated from the first liquid storage member 20.

[0059] Please refer to Figure 7 In one embodiment, the blocking member 6 may include three parts: a positioning portion 611 , a blocking portion 613 and a connecting rod 612 , wherein the positioning portion 611 and the blocking portion 613 are respectively connected to two ends of the connecting rod 612 .

[0060] Specifically, the positioning portion 611 is clamped and fixed in the liquid guide hole 41, and a liquid guide port 610 is specially provided on the positioning portion 611 to provide a channel for the circulation of the aerosol generating matrix. The blocking portion 613 is inserted into the plug port 511 of the plug-in portion 51 to block the plug port 511, that is, to isolate the first liquid storage member 20 from the second liquid storage member 5. One end of the connecting rod 612 is tightly connected to the positioning portion 611, and the other end is connected to the blocking portion 613.

[0061] In this embodiment, the diameter of the connecting rod 612 is smaller than the diameters of the positioning portion 611 and the plugging portion 613 respectively, so that while connecting the positioning portion 611 and the plugging portion 613, the connecting rod 612 will not interfere with the functions of the two. When the second liquid storage member 5 approaches the first liquid storage member 20, the plugging portion 613 moves relatively in the insertion port 511 to avoid the insertion port 511, so that the second liquid storage member 5 is communicated with the first liquid storage member 20; at this time, the aerosol generating matrix can smoothly pass through the insertion port 511, the gap around the connecting rod 612, and the liquid guiding port 610 to realize the transportation from the second liquid storage member 5 to the first liquid storage member 20. When the second liquid storage member 5 moves away from the first liquid storage member 20 under the action of the elastic member 50, the plugging portion 613 will move relatively into the insertion port 511 to plug the insertion port 511, effectively preventing the leakage of the aerosol generating matrix.

[0062] The positioning portion 611 can ensure that the position of the plugging member 6 in the liquid guiding hole 41 is always stable and will not be displaced due to the shaking of the device or other external force factors. The connecting rod 612 ensures that the plugging portion 613 can move relatively outside the insertion port 511 to avoid the insertion port 511, and can ensure that the plugging portion 613 can move relatively into the insertion port 511 to plug the insertion port 511, solve the problem of liquid leakage, and ensure the stable operation of the aerosol generating device 10. The cross sections of the liquid guiding hole 41, the plugging portion 51 and its insertion port 511, and the positioning portion 611 are all circular and are designed to correspond to each other. Of course, polygons can also be used, such as quadrilaterals, etc., which can also be achieved.

[0063] An inner ring groove 412 is provided on the inner wall of the liquid guiding hole 41, and the outside of the positioning portion 611 is embedded in the inner ring groove 412 and fastened by interference fit, and the assembly process is simple.

[0064] Please continue to refer to Figures 1 to 7 Furthermore, the plugging portion 613 mainly includes a clamping wheel and a sealing ring 62. A clamping groove 601 is provided on the circumference of the clamping wheel. When the clamping wheel is installed, it is coaxially arranged with the insertion port 511 to ensure the sealing performance. The sealing ring 62 is tightly sleeved in the clamping groove 601 and forms an interference fit with the inner wall of the insertion port 511, improving the reliability of the plugging effect. When the plugging portion 613 is inserted into the insertion port 511, the interference fit between the sealing ring 62 and the inner wall of the insertion port 511 can form a tight seal, effectively preventing the leakage of the aerosol generating matrix. When selecting the material of the sealing ring 62, a rubber material with high elasticity and chemical corrosion resistance can be selected to extend the service life.

[0065] On the outer periphery of the sealing ring 62, a convex portion 621 extending radially away from the camming wheel along the camming wheel is provided, and the convex portion 621 forms an interference fit with the insertion interface 511. One or more protrusions can be provided. The setting of the convex portion 621 further enhances the sealing effect, and can build multiple sealing lines of defense within the insertion interface 511, effectively preventing the leakage of the aerosol generating matrix.

[0066] When the aerosol generating device 10 is in different usage environments, such as when the temperature and humidity change, the size of the insertion interface 511 may undergo slight changes due to factors such as thermal expansion and contraction. At this time, the convex portion 621 can adapt to these slight changes of the insertion interface 511 through its own elastic deformation, and always maintain a good sealing state. The main part of the sealing ring 62 may be slightly worn due to long-term use. The convex portion 621 can continue to play a sealing role by virtue of its structural characteristics and elastic properties, further improving the anti-liquid leakage effect of the aerosol generating device 10 and enhancing the user experience.

[0067] Please continue to refer to Figures 2 to 5 , in one embodiment, the outer shell is provided with a first connecting portion (not shown in the figure) located in the guiding cavity 101. Correspondingly, the second liquid storage member 5 is provided with a second connecting portion (not shown in the figure). The second connecting portion is connected to the first connecting portion, so that the second liquid storage member 5 is firmly connected to the outer shell, ensuring that the relative position between the second liquid storage member 5 and the first liquid storage member 20 always remains stable, and further ensuring that the blocking member 6 can accurately perform its blocking and conducting functions.

[0068] One of the first connecting portion and the second connecting portion is designed as a stroke limiting hole 102, and the other is designed as a stroke slider 52. The stroke slider 52 can smoothly slide in the stroke limiting hole 102 and be tightly embedded therein. Through the above structural design, not only the reliable connection between the second liquid storage member 5 and the outer shell is realized, but also the function of limiting the pressing stroke of the second liquid storage member 5 is provided.

[0069] When the user operates to press the second liquid storage member 5, the sliding of the stroke slider 52 in the stroke limiting hole 102 can ensure that the second liquid storage member 5 accurately reaches the appropriate position for conducting or isolating with the first liquid storage member 20. At the same time, it can also prevent damage to the device caused by excessive pressing by the user or affecting the sealing effect of the blocking member 6. By precisely limiting the pressing stroke, the reliability of the device is further guaranteed, and the liquid leakage problem that may be caused by improper operation is effectively solved. The stroke slider 52 is provided with a limiting portion 521, and the limiting portion 521 abuts against the outside or inside of the stroke limiting hole 102, so that the stroke slider 52 is restricted in the stroke limiting hole 102, and the phenomenon that the second liquid storage member 5 accidentally detaches from the outer shell can be avoided.

[0070] Please continue to refer to Figure 3 andFigure 7 In one embodiment, a rib portion 411 is formed on the inner wall of the liquid guiding hole 41 near one end of the second liquid storage member 5. The rib portion 411 and the outer periphery of the insertion portion 51 form an interference fit. A plurality of rib portions 411 may be provided, and the plurality of rib portions 411 are spaced apart. The arrangement of the rib portions 411 further enhances the sealing performance between the liquid guiding hole 41 and the insertion portion 51.

[0071] When the insertion portion 51 is inserted into the liquid guiding hole 41, the rib portion 411 can closely fit the outer periphery of the insertion portion 51 to form a tight sealing structure, effectively preventing the aerosol generating matrix from leaking from the connection between the liquid guiding hole 41 and the insertion portion 51. After long-term use, due to frequent pressing operations and various external forces, there may be minute gaps between components due to wear. The elastic deformation ability of the rib portion 411 itself can timely fill these minute gaps generated by wear, and always maintain a good sealing effect.

[0072] Please continue to refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 In one embodiment, the housing includes a first housing 11 and a second housing 12. The first housing 11 and the second housing 12 are arranged side by side. A sleeve 111 is formed by downward extension at the lower end of one side of the first housing 11. A guiding cavity 101 is formed between the sleeve 111 and a guiding groove 121 on the side surface of the second housing 12.

[0073] In this embodiment, the length of the first housing 11 is less than that of the second housing 12, that is, a part of the second housing 12 that is longer than the first housing 11 forms an avoidance space. A guiding groove 121 is formed on one side surface of the second housing 12 facing the avoidance space, and a stroke limiting hole 102 is provided at the bottom of the guiding groove 121. The guiding groove 121 is communicated with the guiding cavity 101. On the one hand, it can ensure that the second liquid storage member 5 can be more stably installed in the guiding cavity 101, and is convenient for stably driving the second liquid storage member 5 to slide when pressing the bottom of the second liquid storage member 5, ensuring the stability of the sealing assembly, and is more conducive to achieving leakage prevention. On the other hand, it is convenient for the user to quickly disassemble the second liquid storage member 5.

[0074] Please refer to Figure 1 、 Figures 8 to 11 In one embodiment, the plugging member 6 includes a plurality of elastic sheets 63. After the plurality of elastic sheets 63 are spliced, they work together to form a plugging layer (not shown in the figure) that can effectively plug the liquid guiding hole 41.

[0075] During use, when the second liquid storage member 5 approaches the first liquid storage member 20 under the pressing of the user, the elastic sheet 63 will be squeezed and thus deformed. This deformation causes gaps to appear between the elastic sheets 63 that were originally closely arranged to form a sealing layer, that is, the sealing layer capable of sealing the liquid guiding holes 41 disappears, the liquid guiding holes 41 become unblocked, enabling the second liquid storage member 5 to communicate with the first liquid storage member 20. The aerosol generating matrix in the second liquid storage member 5 can smoothly pass through the liquid guiding holes 41 and flow into the first liquid storage member 20. When the second liquid storage member 5 gradually moves away from the first liquid storage member 20 under the reset action of the elastic member 50, the elastic sheet 63 will quickly return to its initial state by virtue of its own elastic properties. At this time, the multiple elastic sheets 63 are closely joined and fitted again to re-form a tight sealing layer to seal the liquid guiding holes 41.

[0076] The elastic sheet 63 can be made of a highly elastic rubber material. During the process of pressing the second liquid storage member 5 multiple times, even if it frequently bears the forces of extrusion and recovery, it can still stably perform its own functions, ensuring that the liquid guiding holes 41 are opened in a timely manner when conduction is required and firmly sealing the liquid guiding holes 41 when isolation is required, greatly strengthening the ability to prevent liquid leakage problems and effectively avoiding the leakage of the aerosol generating matrix in the aerosol generating device 10 from the liquid guiding holes 41 in the non-conduction state.

[0077] Please continue to refer to Figure 3 and Figure 8 , further, the aerosol generating device 10 is also equipped with an atomization assembly 7, and the atomization assembly 7 penetrates through the first liquid storage member 20. Specifically, the first liquid storage member 20 is composed of a cup body 2 and a sealing seat 4. The cup body 2 includes a cup cylinder and a top cover connected to one end of the cup cylinder. An air outlet hole is specifically provided on the top cover for discharging the atomized aerosol. The sealing seat 4 is connected to the end of the cup cylinder away from the top cover, and it is provided with an air inlet hole and a liquid guiding hole 41. The cup body 2 and the sealing seat 4 cooperate with each other to enclose a first liquid storage cavity, providing a storage space for the aerosol generating matrix.

[0078] One end of the atomization assembly 7 is communicated with the air outlet hole, and the other end is communicated with the air inlet hole. During the operation of the aerosol generating device 10, the aerosol generating matrix first starts from the second liquid storage member 5, smoothly enters the first liquid storage cavity through the liquid guiding holes 41. Subsequently, under the action of the atomization assembly 7, the aerosol generating matrix is atomized into aerosol, and the generated aerosol enters the air outlet hole and is discharged. At the same time, external air flow enters the atomization assembly 7 from the air inlet hole. This structural design not only ensures that the aerosol generating matrix can be reasonably stored and efficiently transported, but also closely cooperates with structures such as the sealing member 6 to further enhance the ability to prevent liquid leakage. The first liquid storage member 20 further includes a liquid storage cotton 3 disposed in the cup body 2 for adsorbing and storing the liquid aerosol generating matrix.

[0079] The aerosol generating device 10 further includes a bracket 8 installed at the lower end of the sealing seat 4, a microphone 81 installed inside the bracket 8, a control circuit 9 installed inside the housing and positioned below the bracket 8, and a mouthpiece 90 installed at the upper end of the housing. The oil guiding cotton 71 in the atomization assembly 7 contacts the liquid storage cotton 3. The pins 231 of the heating wire 72 in the atomization assembly 7 pass through the sealing seat 4 and the bracket 8 and are electrically connected to the control circuit 9, and the microphone 81 is also electrically connected to the control circuit 9, ensuring that the atomization assembly 7 can adsorb and heat the aerosol generating matrix to generate aerosol.

[0080] The plugging member 6 and the sealing seat 4 can be integrally formed. The elastic piece 63 directly extends from the inner wall of the liquid guiding hole 41 in the radial direction of the liquid guiding hole 41, which can greatly reduce the assembly gap between components. In the assembled structure, the gaps between components are often potential risk points for leakage; through integral molding, these gaps are eliminated, which helps to significantly improve the sealing performance of the aerosol generating device 10; at the same time, since the elastic piece 63 and the sealing seat 4 are of an integral structure, its stability is significantly enhanced. When subjected to the force generated by the insertion and extraction of the second liquid storage member 5, the elastic piece 63 can more reliably recover after deformation, ensuring the plugging effect of the elastic piece 63 on the liquid guiding hole 41. In the actual production process, an advanced injection molding process can be used to integrally form the sealing seat 4 and the elastic piece 63.

[0081] This application provides an aerosol generating device, which includes a main body, a second liquid storage member, an elastic member, and a plugging member. When the second liquid storage member approaches the first liquid storage member and compresses the elastic member, the plugging member will automatically avoid the liquid guiding hole, so that the second liquid storage member and the first liquid storage member are smoothly conducted, ensuring that the aerosol generating matrix in the second liquid storage member can be normally transported to the first liquid storage member through the insertion part and the liquid guiding hole. Under the reset action of the elastic member, the second liquid storage member moves away from the first liquid storage member, and the plugging member will quickly plug the liquid guiding hole to isolate the second liquid storage member from the first liquid storage member, preventing the liquid aerosol generating matrix in the second liquid storage member from flowing out, effectively preventing the leakage of the aerosol generating matrix, and solving the problem of liquid leakage caused by using an additional liquid storage member for liquid supply.

[0082] Certainly, the above are only specific embodiments of this application and do not limit the scope of implementation of this application. Any equivalent changes or modifications made according to the structure, features, and principles described in the scope of this application patent should be included within the scope of this application patent.
