[0024] An aerosol generating device is a product that can turn an aerosol generating matrix into an aerosol through heating or other means.

[0025] Generally, an aerosol generating device includes a housing assembly, an oil cup assembly, an atomizing assembly, and a control assembly.

The control assembly is located within the first mounting cavity, and the oil cup assembly is located within the second mounting cavity. The oil cup assembly contains a liquid storage chamber, and the atomizing assembly is housed within the liquid storage chamber. The atomizing assembly has an atomizing channel penetrating the oil cup assembly and communicating with the suction channel. For ease of assembly, the housing assembly includes at least an outer shell and a first seal, and the oil cup assembly includes at least a cup body and a second seal. The assembly process of the aerosol generating device is as follows: first, the atomizing assembly is placed inside the cup body, and then the second seal is connected to the cup body to complete the assembly of the oil cup assembly; then, the oil cup assembly is placed inside the outer shell, ensuring the atomizing channel is aligned and communicating with the suction channel, and then the second seal is connected to the outer shell to complete the assembly of the housing assembly; finally, the control assembly is installed on the outer shell, and the control assembly is electrically connected to the atomizing assembly. Because aerosol generating devices have many structural components, there are many assembly steps and the assembly is more difficult, resulting in higher production and maintenance costs, and thus higher overall costs.

[0026] In view of the above problems, this application provides an aerosol generating apparatus, which aims to reduce the cost of the aerosol generating apparatus.

[0027] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0028] Please refer to Figure 1 and Figure 2 This application provides a method for heating an aerosol generating matrix to generate an aerosol, including a shell assembly 100, an atomizing assembly 200, and a control assembly 300.

[0029] The housing assembly 100 includes a housing 110, a mouthpiece 120, and a base 130. The mouthpiece 120 is connected to one end of the housing 110, and the base 130 is connected to the other end of the housing 110 away from the mouthpiece 120. An atomizing assembly 200 is housed within the housing 110 and includes an atomizing core 210. The atomizing core 210 heats the aerosol-generating matrix in the housing 110 to generate an aerosol. A control assembly 300 is housed within the base 130 and is electrically connected to the atomizing core 210. The mouthpiece 120 and the base 130 are detachably connected to the housing 110.

[0030] It is understood that, in this embodiment, a liquid storage chamber 111 for storing the aerosol generation matrix is ​​formed within the outer casing 110. A nozzle 120 is connected to one end of the outer casing 110, and a suction channel 121 communicating with the liquid storage chamber 111 is constructed within the nozzle 120. A base 130 is connected to the other end of the outer casing 110 away from the nozzle 120, and an air inlet channel 131 communicating with the liquid storage chamber 111 is constructed within the base 130. The atomizing assembly 200 is housed within the outer casing 110, i.e., the atomizing assembly 200 is housed within the liquid storage chamber 111. The atomizing core 210 has an atomizing channel 211 penetrating the liquid storage chamber 111, with one end of the atomizing channel 211 communicating with the suction channel 121 and the other end communicating with the air inlet channel 131. The atomizing core 210 is used to heat the aerosol generating matrix in the outer shell 110 to generate aerosol. Specifically, the aerosol generating matrix in the storage chamber 111 can enter the atomizing assembly 200, and the atomizing core 210 can heat the aerosol generating matrix entering the atomizing assembly 200 to generate aerosol within the atomization channel 211. When the aerosol generating device is being drawn in, the airflow direction within the aerosol generating device is: outside the aerosol generating device → inlet channel 131 → atomization channel 211 → suction channel 121.

[0031] Optionally, the liquid storage cavity 111 is formed by the outer shell 110 and the base 130. That is, the structure of the outer shell 110 itself forms a cavity structure with one end open. The base 130 is inserted into the outer shell 110 through the opening and is sealed against the inner wall of the outer shell 110. The inner wall of the outer shell 110 and the base 130 together form the liquid storage cavity 111.

[0032] Optionally, the liquid storage chamber 111 is composed of the outer casing 110 and other structures in the aerosol generating device (e.g., Figure 2 The sealing element 500 is enclosed to form a cavity structure with one end open, that is, the structure of the outer shell 110 itself is enclosed to form a cavity structure with one end open. The sealing element 500 is inserted into the outer shell 110 from the opening, and the sealing element 500 is sealed against the inner wall of the outer shell 110. The inner wall of the outer shell 110 and the sealing element 500 enclose to form a liquid storage cavity 111.

[0033] It is understood that the control component 300 is electrically connected to the atomizing core 210, that is, the control component 300 is used to power the atomizing core 210 and to control the working state of the atomizing core 210 (whether it is working, its working power, etc.). For example, the control component 300 includes an airflow sensor switch, a circuit board, and a battery 320. The airflow sensor switch is located at the air intake channel 131. When the airflow rate in the air intake channel 131 reaches the response threshold of the airflow sensor switch, the battery 320 powers the atomizing core 210, and the circuit board controls the atomizing core 210 to work to generate an aerosol in the atomizing airway, and the aerosol can flow into the suction channel 121 with the airflow.

[0034] It is understandable that the nozzle 120 is detachably connected to the housing 110, that is, the nozzle 120 and the housing 110 are connected by detachable connection methods such as snap-fit ​​connection, magnetic connection, threaded connection, plug-in connection, etc.

[0035] It is understandable that the base 130 and the outer shell 110 are detachably connected, that is, the base 130 and the outer shell 110 are connected by detachable connection methods such as snap-fit ​​connection, magnetic connection, and threaded connection.

[0036] In the aerosol generating device provided in this application embodiment, since the housing assembly 100 includes a housing 110, a nozzle 120, and a base 130, with the nozzle 120 connected to one end of the housing 110 and the base 130 connected to the other end of the housing 110 away from the nozzle 120; and the nozzle 120 and the housing 110 are detachably connected, and the base 130 and the housing 110 are detachably connected; therefore, the housing assembly 100 is composed of three modules: the housing 110, the nozzle 120, and the base 130, which can be detachably assembled. The aerosol generating device is composed of the housing assembly 100, the atomizing assembly 200, and the control assembly 300, which can reduce the assembly cost and maintenance cost of the aerosol generating device, thereby reducing the cost of the aerosol generating device.

[0037] It is understood that, in this embodiment of the application, a liquid storage chamber 111 for storing the aerosol generation matrix is ​​formed inside the outer shell 110, which can eliminate the oil cup in the conventional design (i.e., the oil cup and the outer shell 110 are integrated in this embodiment of the application), thereby reducing the number of parts in the aerosol generation device and reducing material and assembly costs.

[0038] Please refer to Figures 2 to 6 In some embodiments, the outer casing 110 is provided with a first connecting structure 112 and a second connecting structure 113.

[0039] Optionally, the first connecting structure 112 and the third connecting structure 132 cooperate to make the base 130 and the outer shell 110 detachably connected, meaning that one of the first connecting structure 112 and the third connecting structure 132 is an internal thread, and the other of the first connecting structure 112 and the third connecting structure 132 is an external thread, and the internal thread and the external thread mesh, so that the base 130 and the outer shell 110 are detachably connected.

[0040] Optionally, the cooperation between the first connecting structure 112 and the third connecting structure 132 to make the base 130 and the outer shell 110 detachably connected means that one of the first connecting structure 112 and the third connecting structure 132 is a slot, and the other of the first connecting structure 112 and the third connecting structure 132 is a plate. The plate is engaged in the slot, so that the base 130 and the outer shell 110 are detachably connected.

[0041] Optionally, the cooperation between the first connecting structure 112 and the third connecting structure 132 to detachably connect the base 130 and the outer shell 110 means that one of the first connecting structure 112 and the third connecting structure 132 is a magnet, and the other of the first connecting structure 112 and the third connecting structure 132 is a magnet or a ferromagnetic structural component.

[0043] Optionally, the second connecting structure 113 and the fourth connecting structure 122 cooperate to make the nozzle 120 and the outer shell 110 detachably connected, meaning that one of the second connecting structure 113 and the fourth connecting structure 122 is a slot, and the other of the second connecting structure 113 and the fourth connecting structure 122 is a plate. The plate is engaged in the slot, so that the nozzle 120 and the outer shell 110 are detachably connected.

[0044] Optionally, the second connecting structure 113 and the fourth connecting structure 122 cooperate to make the nozzle 120 and the outer shell 110 detachably connected, meaning that one of the second connecting structure 113 and the fourth connecting structure 122 is a magnet, and the other of the second connecting structure 113 and the fourth connecting structure 122 is a magnet or a ferromagnetic structural component, and the second connecting structure 113 and the fourth connecting structure 122 are magnetically attracted, so that the nozzle 120 and the outer shell 110 are detachably connected.

[0045] Please refer to Figures 3 to 6 In some embodiments, the first connecting structure 112 is a first retaining part, the second connecting structure 113 is a second retaining part, the third connecting structure 132 is a third retaining part, and the fourth connecting structure 122 is a fourth retaining part. The first retaining part and the third retaining part engage to detachably connect the base 130 to the outer shell 110. The fourth retaining part engages with the second retaining part to detachably connect the nozzle 120 to the outer shell 110.

[0046] In the above embodiments, the first connecting structure 112 and the third connecting structure 132 are snapped together, and the second connecting structure 113 and the fourth connecting structure 122 are snapped together, so that the connection relationship between different modules in the housing assembly 100 is more uniform, the connection structure of the housing assembly 100 is simpler, the production difficulty is lower, the assembly difficulty is lower, the cost of the housing assembly 100 is lower, and thus the cost of the aerosol generating device is lower.

[0048] In the above embodiments, the first connecting structure 112 and the third connecting structure 132 are magnetically connected, and the second connecting structure 113 and the fourth connecting structure 122 are magnetically connected, so that the connection relationship between different modules in the housing assembly 100 is more uniform, the connection structure of the housing assembly 100 is simpler, the production difficulty is lower, the assembly difficulty is lower, the cost of the housing assembly 100 is lower, and thus the cost of the aerosol generating device is lower.

[0049] Please refer to Figure 3 and Figure 4 In some embodiments, the outer casing 110 includes a top plate 114, a first side plate 115, and a second side plate 116. The top plate 114 has a suction port 114-1. The first side plate 115 extends from the top plate 114 toward the base 130, and the first side plate 115 and the top plate 114 enclose a first cavity 117 for accommodating the atomizing assembly 200. The second side plate 116 extends from the top plate 114 away from the first side plate 115. The first side plate 115 has a first connecting structure 112, and the second side plate 116 has a second connecting structure 113.

[0050] In the above embodiment, a portion of the atomizing core 210 is inserted into the suction port 114-1, thereby connecting the atomizing channel 211 with the suction port 114-1. When the aerosol generating device is being suctioned, the airflow direction within the aerosol generating device is: outside of the aerosol generating device → air inlet channel 131 → atomizing channel 211 → suction port 114-1 → suction channel 121.

[0051] In some embodiments, at least a portion of the base 130 covers the periphery of the first side plate 115, and the first connecting structure 112 is disposed on the surface of the first side plate 115 facing away from the first cavity 117, so that the first connecting structure 112 can be engaged with the third connecting structure 132. Alternatively, in other embodiments, at least a portion of the base 130 is received within the first cavity 117, and the first connecting structure 112 is disposed on the surface of the first side plate 115 facing the first cavity 117, so that the first connecting structure 112 can be engaged with the third connecting structure 132.

[0052] Please refer to Figure 2 In some embodiments, the first side plate 115 extends from the edge of the top plate 114 toward the base 130, that is, the outer surface of the first side plate 115 is flush with the outer surface of the top plate 114, so as to improve the aesthetics of the aerosol generating device.

[0053] In some embodiments, at least a portion of the suction nozzle 120 is disposed around the periphery of the second side plate 116, and the second connecting structure 113 is disposed on the outer surface of the second side plate 116 so as to facilitate the second connecting structure 113 and the fourth connecting structure 122 to be connected. Alternatively, in other embodiments, at least a portion of the suction nozzle 120 is housed within the second side plate 116, and the second connecting structure 113 is disposed on the inner surface of the second side plate 116 so as to facilitate the second connecting structure 113 and the fourth connecting structure 122 to be connected.

[0054] Please refer to Figures 2 to 4 In some embodiments, the outer casing 110 further includes a third side plate 118. The third side plate 118 extends from the top plate 114 in a direction away from the first side plate 115, and surrounds the periphery of the second side plate 116. The third side plate 118, the second side plate 116, and the top plate 114 together form a mounting groove 1110. The suction nozzle 120 includes an integrally formed suction portion 123 and a plug portion 124. The plug portion 124 is inserted into the mounting groove 1110, that is, the plug portion 124 covers the periphery of the second side plate 116.

[0055] In some embodiments, the third side plate 118 extends from the edge of the top plate 114 in a direction away from the first side plate 115, such that the third side plate 118 is flush with the first side plate 115 in the direction from the second side plate 116 to the third side plate 118, and the third side plate 118 is flush with the suction part 123, so as to improve the aesthetics of the aerosol generating device.

[0056] In the above embodiments, the top plate 114, the first side plate 115, the second side plate 116 and the third side plate 118 are an integral structure, which can reduce the assembly cost of the housing assembly 100.

[0057] Please refer to Figure 2 In some embodiments, the second side plate 116 and the top plate 114 surround to form a second cavity 119. The aerosol generating device also includes a liquid suction member 400, which is housed in the second cavity 119.

[0058] In the above embodiment, the suction part 123 covers the opening of the second cavity 119, so that the suction part 123, the second side plate 116 and the top plate 114 enclose a closed space to prevent the liquid suction member 400 from leaving the second cavity 119.

[0059] Understandably, because the temperature inside the suction channel 121 is lower than that inside the atomization channel 211, the aerosol tends to condense into a liquid state within the suction channel 121 as it flows from the atomization channel 211 to the suction channel 121. By providing a liquid-absorbing element 400 in the second cavity 119, the liquid-absorbing element 400 can absorb the liquid droplets that condense upon cooling, thus preventing leakage.

[0060] Please refer to Figure 2 In the above embodiment, the liquid suction member 400 has an air passage 410. One end of the air passage 410 is opposite to and connected to the suction port 114-1, and the other end of the air passage 410 is opposite to and connected to the suction channel 121. When the aerosol generating device is suctioned, the airflow direction in the aerosol generating device is: outside of the aerosol generating device → air inlet channel 131 → atomization channel 211 → suction port 114-1 → air passage 410 → suction channel 121.

[0061] In some embodiments, the suction member 400 has a first surface and a second surface disposed opposite to each other, the first surface being attached to the suction nozzle 120 and the second surface being attached to the top plate 114.

[0062] In the above embodiment, the first surface is attached to the suction nozzle 120, which can seal the gap between the suction member 400 and the suction nozzle 120, and the second surface is attached to the top plate 114, which can seal the gap between the suction member 400 and the top plate 114, thereby improving the sealing performance by increasing the space between the suction nozzle 120 and the top plate 114.

[0063] With the above settings, the sealing silicone between the nozzle 120 and the housing 110 in the conventional design can be eliminated, thereby reducing the number of parts in the housing assembly 100 and lowering material and assembly costs.

[0064] In some embodiments, a first adhesive layer is provided on the first surface and is bonded to the nozzle 120, and a second adhesive layer is provided on the second surface and is bonded to the top plate 114, which can reduce the difficulty of splicing the liquid suction component 400, the housing and the nozzle 120.

[0065] Please refer to Figure 2 In some embodiments, the aerosol generating device further includes a seal 500, which is housed in a first cavity 117. The seal 500 divides the first cavity 117 into a first sub-cavity and a second sub-cavity, with the atomizing component 200 housed in the first sub-cavity and the base 130 and control component 300 housed in the second sub-cavity.

[0066] In the above embodiment, the first sub-cavity is a liquid storage cavity 111. A mounting hole 510 is provided on the sealing member 500. The end of the atomizing core 210 facing away from the nozzle 120 is inserted into the mounting hole 510, and the atomizing channel 211 communicates with the air inlet channel 131 through the mounting hole 510. When the aerosol generating device is drawn in, the airflow direction within the aerosol generating device is: outside the aerosol generating device → air inlet channel 131 → mounting hole 510 → atomizing channel 211 → suction port 114-1 → air passage 410 → suction channel 121.

[0067] In the above embodiment, the sealing member 500 abuts against the inner wall of the outer casing 110 to improve the airtightness of the liquid storage chamber 111.

[0068] Optionally, the seal 500 can be made of silicone, rubber, or other materials that provide a certain level of support and elasticity. This ensures that the seal 500 has sufficient support while also meeting the sealing requirements of the liquid storage chamber 111.

[0069] In the above embodiment, when assembling the aerosol generating device, the atomizing component 200 is first inserted into the mounting hole 510, and then the atomizing component 200 and the sealing component 500 are inserted into the first cavity 117. This simplifies the assembly steps of the aerosol generating device, reduces the assembly time of the aerosol generating device, and lowers the assembly difficulty of the aerosol generating device.

[0070] Please refer to Figure 2 , Figure 6 and Figure 7 In some embodiments, the base 130 includes a base plate 133, a partition plate 134, and two support plates 135. The base plate 133 and the partition plate 134 are spaced apart and opposite to each other. The two support plates 135 are spaced apart and opposite to each other, and each end of the support plate 135 is connected to the base plate 133 and the partition plate 134, respectively. The base plate 133, the partition plate 134, and the two support plates 135 form a receiving cavity 131-2 for housing the control assembly 300. Each support plate 135 has a third connecting structure 132 on its surface opposite to the receiving cavity 131-2.

[0071] In the above embodiment, the base plate 133 has an air inlet 131-1 communicating with the receiving cavity 131-2, and the partition plate 134 has an air outlet 131-3 communicating with the receiving cavity 131-2. The air inlet 131-1, the receiving cavity 131-2, and the air outlet 131-3 together form an air intake channel 131. When the aerosol generating device is drawn in, the airflow direction inside the aerosol generating device is: outside of the aerosol generating device → air inlet 131-1 → receiving cavity 131-2 → air outlet 131-3 → mounting hole 510 → atomization channel 211 → suction port 114-1 → air passage 410 → suction channel 121.

[0072] Please refer to Figure 6 and Figure 7 In some embodiments, the seal 500 is provided with a fifth connecting structure 520, and the partition 134 is provided with a sixth connecting structure 136 adapted to the fifth connecting structure 520. The fifth connecting structure 520 and the sixth connecting structure 136 cooperate to define the relative positions of the seal 500 and the partition 134 in the distribution direction of the base plate 133 and the partition 134.

[0073] In the above embodiment, when assembling the aerosol generating device, the base 130 and the sealing element 500 are connected first, the atomizing component 200 is inserted into the mounting hole 510, and then the atomizing component 200, the sealing element 500 and the base 130 are inserted into the first cavity 117. This simplifies the assembly steps of the aerosol generating device, reduces the assembly time of the aerosol generating device, and lowers the assembly difficulty of the aerosol generating device.

[0074] Please refer to Figure 6 and Figure 7 In some embodiments, the fifth connecting structure 520 includes a first slot 521 formed on the seal 500 and a limiting portion 522, the limiting portion 522 being connected to the sidewall of the first slot 521 and covering a portion of the opening of the first slot 521. The sixth connecting structure 136 includes a second slot formed on the base 130, a portion of the base 130 being received in the first slot 521, and the limiting portion 522 being received in the second slot to define the relative positions of the seal 500 and the partition 134 in the distribution directions of the base plate 133 and the partition 134.
