[0050] The following further describes the atomization cartridge 10 provided by the present application in conjunction with the accompanying drawings and specific embodiments.

[0051] Embodiment 1

[0052] Referring to Figures 1-8 as shown, Figure 1 is a schematic structural diagram of the atomization cartridge 10 in the first embodiment provided by the present application, Figure 2 is an explosion schematic diagram of the atomization cartridge 10 in the first embodiment provided by the present application, Figure 3 is a partial cross-sectional view of the atomization cartridge 10 in the first embodiment of the present application, Figure 4 is a partial enlarged view of the atomization cartridge 10 in the first embodiment of the present application, Figure 5 is a schematic structural diagram of the atomization cartridge 10 in the second embodiment provided by the present application, Figure 6is a schematic diagram of the explosion of the atomizer bomb 10 in the second embodiment provided in the present application, Figure 7 is a partial cross-sectional view of the atomizer bomb 10 in the second embodiment of the present application, Figure 8 It is a partial enlarged view of the atomizing bomb 10 in the second embodiment of the present application.

[0053] See also Figures 1-8 As shown, embodiment 1 discloses an atomizer bomb 10, which includes an atomizer tube 11 and a receiving cup 13, wherein the receiving cup 13 is detachably connected to the atomizer tube 11, the receiving cup 13 defines a receiving cavity 62, the atomizer tube 11 has a smoking nozzle 111 at one end away from the receiving cup 13, the smoking nozzle 111 is provided with a smoking port 61, the atomizer tube 11 is provided with an atomization channel 63, and the receiving cavity 62, the atomization channel 63, and the smoking port 61 are connected.

[0054] Specifically, the atomizer tube 11 and the receiving cup 13 are extended in the longitudinal direction, and the receiving cup 13 is provided with an end wall 131 at one end facing away from the atomizer tube 11, and the receiving cup 13 is provided with a first opening 64 at one end facing the atomizer tube 11, and a receiving cavity 62 is defined between the end wall 131 and the first opening 64. The heating element 24 heats the atomization matrix in the receiving cup 13 by thermal radiation to form an aerosol, and the aerosol circulates along the first opening 64, the atomization channel 63 and the smoking mouthpiece 111, and is finally inhaled by the user at the smoking mouthpiece 111.

[0055] In a preferred embodiment, the containing cup 13 is detachably connected to the atomizer tube 11. After the user has consumed the atomizer matrix in the containing cup 13, the containing cup 13 and the atomizer tube 11 can be disassembled for cleaning, and then new atomizer matrix can be added to the containing cup 13, or a new containing cup 13 and atomizer tube 11 can be replaced for use. This improves the reusability of the product while avoiding the problem of residual atomizer matrix causing harm to human health. Compared with the prior art in which the cup body is integrated into the smoking device 20, the atomizer cartridge 10 in the present application has the advantages of being easy to replace, clean, and carry.

[0056] The containing cup 13 is made of a transparent or translucent material with good heat conduction efficiency and heat resistance in order to ensure the heating effect and facilitate the user to observe the consumption of the atomized matrix. Optionally, the containing cup 13 is made of glass, quartz, ceramic, agate, etc.

[0057] The atomizing cartridge 10 further includes a limiting connection part 12. The limiting connection part 12 includes a hollow tube. One end of the hollow tube has a first closed wall 124. The other end of the hollow tube is connected to the atomizing tube. The atomizing tube 11 is detachably connected to the receiving cup 13 through the limiting connection part 12. In order to prevent the limiting connection part 12 from releasing harmful components in a high-temperature environment and causing harm, the limiting connection part 12 is preferably made of a high-temperature resistant material.

[0058] Specifically, referring to Figure 4 As shown, the hollow tube includes a first tube 121 and a second tube 122 connected to each other. The first tube 121 has a reduced diameter relative to the second tube 122 and a first limiting step 125 is formed on the outer periphery thereof. The first tube 121 is detachably inserted into the receiving cup 13. The end of the receiving cup 13 having a first opening 64 abuts against the first limiting step 125. The circumference of the first tube 121 is adapted to the first opening 64 of the receiving cup 13, which facilitates the user to install from different angles.

[0059] The first tube 121 and the second tube 122 can be directly connected, or can be integrally formed or welded.

[0060] In some examples, in order to prevent the atomizing matrix in the receiving cup 13 that is heated but not atomized from flowing out of the smoking port 61 along the atomizing channel 63 and scalding the user, a first closed wall 124 is provided in the middle of the limiting connection part 12. At least one first through hole 1241 is opened on the first closed wall 124. The first through hole 1241 is used for the aerosol to flow from the receiving cavity 62 to the atomizing channel 63. Specifically, the first closed wall 124 is located at the end of the first tube 121 away from the second tube 122. In other examples, the first closed wall 124 can also be located at any position inside the first tube 121. The receiving cavity 62 communicates with the atomizing channel 63 through the first through hole 1241 of the limiting connection part 12.

[0061] Furthermore, a second closed wall 113 is provided in the atomizing tube 11. The second closed wall 113 is horizontally arranged in the atomizing channel of the atomizing tube 11. At least one third through hole 1131 is opened on the second closed wall 113. The receiving cavity 62 communicates with the smoking port 61 through the first through hole 1241 and the third through hole 1131. Through the blocking of the first closed wall 124 and the second closed wall 113, it is effectively avoided that the unheated atomizing matrix enters the user's mouth along the atomizing channel 63 from the smoking port 61.

[0062] See Figure 8 , at least one fourth through hole 1311 is opened on the end wall 131 of the receiving cup 13. External air enters the receiving cavity 62 through the fourth through hole 1311, carries the aerosol and enters the atomizing channel 63 through the first through hole 1241.

[0063] See Figure 4 As shown, further, the limiting connection portion 12 may further include a third tube 123. The second tube 122 has a reduced diameter relative to the third tube 123, and a second limiting step 1213 is formed on the outer periphery thereof. The atomizing tube 11 is connected to one end of the third tube 123 away from the second tube 122.

[0064] Embodiment 2

[0065] On the basis of Embodiment 1, further add: Refer to Figures 5-8 , a second through hole 1213 is formed on the peripheral wall of the first tube 121. The second through hole 1213 can communicate the accommodation cavity 62 with the atomization channel 63. The second through holes 1213 formed on the peripheral wall and arranged uniformly contribute to the stability of the air flow. While effectively avoiding the backflow of the atomization matrix, the stability of the air flow is also ensured.

[0066] Embodiment 3:

[0067] On the basis of Embodiment 2, further add: Refer to Figures 5-8 , at least one concave portion 1211 and at least one convex portion 1212 extending along the axial direction are formed on the outer peripheral wall of the first tube 121. A plurality of concave portions 1211 and a plurality of convex portions 1212 are arranged alternately. The second through hole 1213 is arranged in the concave portion 1211 of each first tube 121.

[0068] A rib 1214 corresponding to each concave portion 1211 is formed by the first limiting step 125 protruding towards the accommodation cavity 62. The rib 1214 and the convex portion 1212 are respectively in contact with the inner wall of the accommodation cup 13. A gap 1215 is left between the rib 1214 and the convex portion 1212 to communicate the second through hole 1213 with the accommodation cavity 62. A tightly fitted detachable connection can be achieved between the accommodation cup 13 and the rib 1214.

[0069] At least one notch 1221 is formed by the first limiting step 125 concaving in the direction away from the accommodation cavity 62. Each notch 1221 communicates with the second through hole 1213 through the gap 1215. External air flow can also bring the aerosol generated by the accommodation cup into the atomization channel 63 through the notch 1221 and the gap 1215 and into the second through hole 1213 and the first through hole 1241.

[0070] Embodiment 4

[0071] The difference from Embodiment 1 is: Refer to Figures 1-4, there is no fourth through hole 1311 on the end wall 131 of the receiving cup 13, which facilitates the accommodation of paste-like, liquid-like, or oil-like atomization matrix without leakage. A second through hole 1213 is provided on the peripheral wall of the first tube 121. The second through hole 1213 can communicate the accommodation cavity 62 with the atomization channel 63. The second through hole 1213 is provided on the peripheral wall. At least one concave portion 1211 and at least one convex portion 1212 extending axially are formed on the outer peripheral wall of the first tube 121. The plurality of concave portions 1211 and the plurality of convex portions 1212 are alternately arranged. The second through hole 1213 is provided in the concave portion 1211 of each first tube 121. A rib 1214 corresponding to each concave portion 1211 is protruded from the first limiting step 125 toward the accommodation cavity 62. The rib 1214 and the convex portion 1212 are respectively abutted against the inner wall of the receiving cup 13. A gap 1215 is left between the rib 1214 and the convex portion 1212 to communicate the second through hole 1213 with the accommodation cavity 62. A tightly fitted and detachable connection can be achieved between the receiving cup 13 and the rib 1214. At least one notch 1221 is recessed from the first limiting step 125 in a direction away from the accommodation cavity 62. Each notch 1221 communicates with the second through hole 1213 through the gap 1215. External air flow can only bring the aerosol generated by the receiving cup into the atomization channel 63 from the second through hole 1213 and the first through hole 1241 through the notch 1221 and the gap 1215.

[0072] Embodiment 5

[0073] The difference from Embodiment 4 is that: there is no first through hole 1241 on the first closing wall 124. Therefore, external air flow can only bring the aerosol generated by the receiving cup into the atomization channel 63 from the second through hole 1213 through the notch 1221 and the gap 1215.

[0074] The present application also discloses an aerosol generating device 100, which includes a smoking device 20 and an atomization cartridge 10 according to any one of Embodiments 1-5 above. The atomization cartridge 10 is used to store an atomization matrix, and the smoking device 20 is used to heat the atomization matrix in the atomization cartridge 10 to form an aerosol.

[0075] Refer to Figures 9-13 as shown Figure 9 is a schematic structural diagram of the aerosol generating device 100 provided by the present application, Figure 10 is a schematic structural diagram of the aerosol generating device 100 from another angle provided by the present application, Figure 11 is an assembly schematic diagram of the smoking device 20 and the atomization cartridge 10 in the aerosol generating device 100 provided by the present application, Figure 12 is an explosion schematic diagram of the aerosol generating device 100 provided by the present application, Figure 13It is a cross-sectional view of the smoking device 100 provided by this application.

[0076] Specifically, as Figures 9-13 shown, the smoking device 20 is provided with an installation cavity 51. The smoking device 20 has a second opening 53 corresponding to the installation cavity 51. A heating element 24 is arranged in the installation cavity 51. The atomizing cartridge 10 is inserted into the installation cavity 51 from the direction of the second opening 53 so that the receiving cup 13 of the atomizing cartridge 10 faces the heating element 24. When the heating element 24 is powered on and heated, the atomizing matrix in the receiving cup 13 is heated to form an aerosol for the user to inhale.

[0077] The smoking device 20 is provided with an air inlet hole 52. The air inlet hole 52 is communicated with the installation cavity 51. Through the user's suction movement, the air inlet hole 52 can allow air to enter the installation cavity 51, and then enter the receiving cavity 62 to be mixed with the aerosol and brought to the smoking mouth part 111.

[0078] In some preferred embodiments, the atomizing cartridge 10 and the smoking device 20 are configured to be detachably connected, and the detachable connection method can be set as at least one of elastic connection, magnetic attraction connection, screw connection or snap connection. When the atomizing matrix stored in the atomizing cartridge 10 is consumed, the user can replace the atomizing cartridge 10 with a new one and reuse it, avoiding the residues after the atomizing matrix is burned from polluting the receiving cup, the atomizing tube and the smoking mouth part, affecting the taste and endangering the user's health.

[0079] As Figure 3 and Figure 7 shown in an embodiment provided, a locking member 14 is arranged on the periphery of the atomizing tube 11 of the atomizing cartridge 10. The locking member 14 is an elastic element. The atomizing cartridge 10 realizes the movable connection with the installation cavity 51 through the characteristics of the elastic element. When the atomizing cartridge 10 is installed in the installation cavity 51, the locking member 14 of the atomizing cartridge 10 elastically abuts against the inner wall of the installation cavity 51. When the atomizing cartridge 10 is disassembled, the locking member 14 elastically deforms so that the atomizing cartridge 10 can be detached from the installation cavity 51. At the same time, the locking member 14 can closely fit on the inner wall of the installation cavity 51 to ensure the airtightness of the installation cavity 51, avoiding external gas from entering the receiving cavity 62 through the air inlet hole 52 and flowing out along the joint between the atomizing cartridge 10 and the receiving cavity 62. The elastic element includes but is not limited to silica gel or plastic, etc.

[0080] The atomizing tube 11 of the atomizing cartridge 10 is provided with a convex portion 112. The locking member 14 is sleeved on the periphery of the convex portion 112. It can be understood that the convex portion 112 is arranged at the position of the atomizing tube 11 opposite to the installation cavity 51 so that the locking member 14 can abut against the inner wall of the installation cavity 51.

[0081] The smoking device 20 includes a housing 27, a battery 28, and a control component 29. The housing 27 can be formed by connecting several components, or it can be an integral component. For example, Figure 12 as shown in the figure, the housing 27 includes a first shell 271 and a second shell 272. The first shell 271 and the second shell 272 enclose and define a chamber 71. The battery 28 and the control component 29 are installed in the chamber 71. The battery 28, the control component 29, and the heating element 24 are electrically connected to each other, so that the battery 28 provides power for driving the heating element 24, and the control component 29 is used for power supply and controlling the heating element 24 according to a specific program logic.

[0082] In the above embodiment, the control component 29 integrates a power supply interface, an airflow sensor, a display screen, a calculation unit, etc. Among them, the power supply interface is used to connect to an external power supply to charge the battery 28. The airflow sensor is used to sense the air pressure change and transmit analog or digital signals to the calculation unit for processing. The display screen is used to display the interface, allowing the operator to monitor the system status, adjust parameters, and perform manual control. The calculation unit can receive signals from various sensors, analyze and logically judge the input signals according to preset control strategies and algorithms, and formulate corresponding control decisions. Exemplarily, when the control unit receives the electrical signal from the airflow sensor, it issues an electrical signal to control the open and closed circuit between the heating unit and the battery 28, or receives the parameter adjustment by the user through the display screen, so as to control the output power of the battery 28.

[0083] The battery 28 can be configured in any form in the prior art and is not specifically limited in the embodiments of the present application.

[0084] In some instances, the air inlet hole 52 is provided on the housing 27. For example, Figure 12 as shown in the figure, the air inlet hole 52 is provided on the first shell 271, and the air inlet hole 52 is provided at one end of the first shell 271 away from the second opening 53.

[0085] In some instances, the heating element 24 heats the atomization matrix by thermal radiation to form an aerosol for the user to inhale. For example, Figure 12 as shown in the figure, the heating element 24 is in a hollow cylindrical shape. The peripheral wall of the heating element 24 is made of a resistive material. A plurality of round holes are arranged in an array on the peripheral wall of the heating element 24. The heating element 24 surrounds the periphery of the heating cup. After the heating unit is powered on, it generates heat, and the heat heats the atomization matrix in the receiving cup 13 in the form of radiation.

[0086] Further, the heating element 24 is in direct contact with the containing cup 13, is spaced apart, or there is other material between the heating element 24 and the containing cup 13 to conduct heat. In a preferred embodiment of the present application, the heating element 24 is spaced apart from the containing cup 13 to prevent the heating element 24 from being in direct contact with the containing cup 13. Excessively high temperature may cause the containing cup 13 to deform or precipitate some impurities at high temperature, affecting the taste of the smoke. At the same time, it avoids the oxidation of the heating element 24 and improves the service life.

[0087] In the above examples, the resistive material of the heating element 24 includes materials such as nickel, iron, stainless steel, nickel-iron alloy, nickel-chromium alloy, iron-chromium-aluminum alloy, or metallic titanium, or a conductive material containing at least one of the above. Thus, when conducting electricity, it can generate heat through resistance to heat the atomization matrix, causing at least one component in the atomization matrix to volatilize and form an aerosol.

[0088] In some examples, the heating element 24 is disposed at one end of the installation cavity 51 close to the air inlet and far from the second opening 53, preventing the heating element 24 from overheating during use and affecting the user experience.

[0089] In some examples, the smoking device 20 further includes a heat insulation sleeve 25. The heat insulation sleeve 25 is slightly larger than the heating element 24 and wraps around the periphery of the heating element 24. The heat insulation sleeve 25 can reduce the heat dissipation of the heating element 24 to the surrounding environment, thereby maintaining the temperature in the installation cavity 51, reducing unnecessary heat energy loss. At the same time, it avoids the local high temperature of the heating element 24 during operation, which may affect the user experience. The use of the heat insulation sleeve 25 can reduce the surface temperature of these areas and reduce the risk of scalding the user during contact, improving the user experience.

[0090] To achieve the above functions, the heat insulation sleeve 25 includes, but is not limited to, materials such as fiberglass insulation material, heat insulation cotton, and silicon ceramics. In the present application, it is preferably asbestos material, which has the technical advantages of stable chemical properties and high heat insulation efficiency.

[0091] In some examples, the smoking device 20 further includes a first positioning tube 23 and a second positioning tube 22. The second positioning tube 22 is located at one end of the first positioning tube 23 far from the second opening 53. The inner circumferences of the first positioning tube 23 and the second positioning tube 22 enclose the installation cavity 51 to isolate the installation cavity 51 from the chamber 71, improving the airtightness of the installation cavity 51. Good airtight performance ensures that the mixing ratio of air and e-liquid remains consistent each time when inhaling, thereby providing a uniform air volume and a consistent taste experience.

[0092] In some examples, the smoking device 20 further includes a bottom cover 26.

[0093] See Figure 14, in some instances, a boss 233 protruding radially inward is provided in the installation cavity 51, and the boss 233 cooperates with the atomizing cartridge 10 to make the receiving cup 13 face the heating element 24, as Figure 14 shown in an example, when the atomizing cartridge 10 is installed in the smoking device 20, the first limiting step 125 of the atomizing cartridge 10 abuts against the boss 233 to make the receiving cup 13 face the heating element 24; as Figure 15 shown in another example, when the atomizing cartridge 10 is installed in the smoking device 20, the second limiting step 1213 of the atomizing cartridge 10 abuts against the boss 233 to make the receiving cup 13 face the heating element 24.

[0094] In some instances, the first positioning tube 23 includes a first tube body 231 and a second tube body 232 connected to each other. The inner diameter of the first tube body 231 is larger than that of the second tube body 232. The second tube body 232 forms a step inside relative to the first tube body 231. The heat insulation sleeve 25 is arranged on the inner wall of the first tube body 231 and is located between the step and the second positioning tube 22. The tube body of the second positioning tube 22 extends from the second opening 53 to the end of the first tube body 231. The boss 233 protrudes from the second tube body 232 of the first positioning tube 23.

[0095] It should be noted that although there are some cartridge-based e-cigarettes on the market, the atomization matrix in cartridge-based e-cigarettes is generally a relatively thin liquid atomization matrix composed of propylene glycol, glycerin, alcohol, tobacco extract, nicotine, tobacco flavor, plant extract, etc. The heating element 24 is integrated in the cartridge and directly contacts the e-liquid. At the same time, due to volume limitations, the output power of the heating element 24 is relatively low, and the above components can achieve heating work at a relatively low power. However, the atomization matrix of the present application may include a liquid aerosol-forming matrix, a viscous paste-like aerosol-forming matrix, or a solid aerosol-forming matrix. For example, shisha paste, fireworks, etc. Due to their texture, shisha paste and fireworks cannot be directly contacted with the atomization core for heating. In the present application, the heating element 24 is arranged in the installation cavity 51 to heat the atomization matrix in the atomizing cartridge 10 by thermal radiation. The heating element 24 is connected to the battery 28 for power supply. At the same time, regardless of volume limitations, the power of the heating element 24 can be increased to directly heat shisha paste and fireworks.

[0096] The working state of the atomizing cartridge 10 in the smoking device 20 will be described below in conjunction with specific embodiments and the accompanying drawings.

[0097] Refer to Figure 14As shown, the atomizing cartridge 10 of Embodiment 4-5 is inserted into the receiving cavity 62 of the smoking device 20. The second limiting step 1213 on the atomizing cartridge 10 cooperates with the boss 233, so that the receiving cup 13 of the atomizing cartridge 10 is opposite to the heating area of the heating element 24. External air enters the installation cavity 51 from the air inlet hole 52, and enters the receiving cavity 62 along the notch 1221 through the gap between the receiving cup 13 and the inner wall of the installation cavity 51. The mixture of air and aerosol enters the atomizing channel 63 along the first through hole 1241 and the second through hole 1213, and is finally inhaled by the user at the smoking port 61.

[0098] Reference Figure 15 As shown, the atomizing cartridge 10 disclosed in Embodiments 1-3 is inserted into the receiving cavity 62 of the smoking device 20. The second limiting step 1213 on the atomizing cartridge 10 cooperates with the boss 233, so that the receiving cup 13 of the atomizing cartridge 10 is opposite to the heating area of the heating element 24. External air enters the installation cavity 51 from the air inlet hole 52, and the mixture of the aerosol passing through the fourth through hole 1311 on the receiving cup 13 enters the atomizing channel 63 along the first through hole 1241 and the second through hole 1213, and is finally inhaled by the user at the smoking port 61.
