[0049] In a first aspect, please refer to Figures 1-8 , an embodiment of the present application provides a main unit 10, which is used for an aerosol generating device 100 and can optimize the use experience of the aerosol generating device 100.

[0050] Specifically, please refer to Figures 1-3 , the main unit 10 includes an identification component 11 and a controller 12. The identification component 11 is used to identify the inserted atomizer 20. The identification component 11 has an output positive electrode 111 and an output negative electrode 112 arranged at intervals. One of the output positive electrode 111 and the output negative electrode 112 has a quantity of two, and the other has a quantity of one; the controller 12 is electrically connected to the identification component 11, and the controller 12 is used to adjust the output power according to the identification result of the identification component 11; wherein, when the atomizer 20 is connected to the identification component 11, at least one output positive electrode 111 and at least one output negative electrode 112 are connected to the atomizer 20.

[0051] The above-mentioned controller 12 and the identification component 11 cooperate with each other. When the atomizer 20 is inserted, according to the different required powers of the atomizer 20, different atomizers 20 will respectively cooperate with different output positive electrodes 111 and output negative electrodes 112. At this time, the controller 12 can identify the required power of the atomizer 20 according to the different output positive electrodes 111 and output negative electrodes 112 used for cooperating with the atomizer 20 at the identification component 11; subsequently, the controller 12 can adjust the power according to the identified result, so that the output power of the main unit 10 can be adjusted as the atomizer 20 changes. Compared with the related art, the main unit 10 provided by the present application has the effect of identifying atomizers 20 with different atomization powers and adjusting the output power according to the identified result. At this time, the main unit 10 can be adapted to a variety of atomizers 20 with different atomization powers, has stronger applicability, and helps to improve the user's use experience.

[0052] The above adjustment of the output power can be understood as switching or selecting among multiple different output powers.

[0053] Please refer toFigure 2 and Figure 3 As described above, the number of the output positive electrodes 111 is two, and the number of the output negative electrodes 112 is one. The controller 12 is a PCB (Printed Circuit Board) with data processing and control functions. An MCU (Micro controller Unit) for adjusting power is also provided inside the PCB. The above-mentioned identification component 11 is electrically connected to the controller 12. When the category of the electrodes (including the output positive electrode 111 and the output negative electrode 112) connected to the atomizer 20 in the identification component 11 changes, the electrical parameters detected by the PCB change. At this time, the MCU can adjust the output power according to the change of the electrical parameters detected by the PCB.

[0054] The structures and working methods of the above-mentioned MCU and PCB are prior arts and will not be elaborated here.

[0055] It should also be noted that, please refer to Figure 2 and Figure 3 As described above, the above-mentioned identification component 11 can achieve three different identification results through the output positive electrode 111 and the output negative electrode 112. Define the two output positive electrodes 111 as electrode one and electrode two respectively, and the output negative electrode 112 as electrode three. The above three identification results are respectively: the atomizer 20 is connected to electrode one and electrode three, the atomizer 20 is connected to electrode two and electrode three, and the atomizer 20 is connected to electrode one, electrode two and electrode three simultaneously. For the controller 12, according to the preset program, corresponding to the corresponding identification result, and output the set power value.

[0056] At this time, the host 10 can cooperate with a variety of atomizers 20 with different atomization powers, and output a suitable power resistance according to the required power of the atomizer 20.

[0057] Please refer to Figure 1 and Figure 4 As shown in

[0058] The above-mentioned controller 12 is also fixed on the bracket 14.

[0059] In some embodiments, a wake-up channel 142 is formed on the above-mentioned bracket 14. One end of the wake-up channel 142 is communicated with the air intake trigger channel 21 of the atomizer 20, and the other end is communicated with the air pressure sensor 15 through a first air guide through hole 1411 penetrating the fixing part 141.

[0060] Specifically, a part of the above-mentioned wake-up channel 142 is formed in the fixing part 141. The wake-up channel 142 is used to communicate the air pressure sensor 15 and the air intake trigger channel 21 of the atomizer 20, so as to ensure that the air pressure sensor 15 for identifying the user's suction action can and only can be connected to the external environment through the wake-up channel 142, and is separated from other parts in the main unit 10, ensuring that the air pressure sensor 15 can be in a better sealed state, thereby avoiding the leakage of condensed liquid or oil-like substances that may be formed when the atomizer 20 works to the location where the air pressure sensor 15 is located, ensuring the cleanliness of the location where the air pressure sensor 15 is located, and protecting the air pressure sensor 15 from being damaged.

[0061] For the structure after the atomizer 20 is combined with the main unit 10, please refer to Figures 9-10 . When the atomizer 20 is connected to the main unit 10 through the socket 131, the air intake trigger channel 21 formed on the atomizer 20 can just be opposite to and communicate with the wake-up channel 142 on the bracket 14. At this time, the aerosol channel 22 formed on the atomizer 20 is independently arranged relative to the wake-up channel 142, and there is no direct gas exchange between the two, so it can effectively avoid the aerosol flowing into the air intake trigger channel 21, which helps to protect the air pressure sensor 15 located at the end of the air intake trigger channel 21.

[0062] In some embodiments, please refer to Figures 4-5 , one end of the first air guide through hole 1411 on the above-mentioned fixing part 141 facing away from the air pressure sensor 15 protrudes relative to the surface of the fixing part 141, that is, relative to the top wall. At this time, the top wall of the first air guide through hole 1411 protrudes relative to the top wall of the fixing part 141, so that a stepped hole structure is formed at the end of the first air guide through hole 1411 facing the top wall of the fixing part 141. When some liquid impurities fall on the top wall of the fixing part 141, the above-mentioned stepped hole helps to block the impurities from directly flowing into the first air guide through hole 1411, which can help reduce the possibility of impurities entering the air intake trigger channel 21 through the first air guide through hole 1411 and contaminating the air pressure sensor 15 to a certain extent.

[0063] In some embodiments, in order to further improve the sealing effect of the air pressure sensor 15 inside the main unit 10, please refer to Figure 4 and Figure 6 , a first sealing member 16 for blocking one end of the atomizer 20 facing the fixing part 141 is further provided inside the housing 13. When the atomizer 20 is connected to the main unit 10 through the socket 131, the atomizer 20 is in contact with the first sealing member 16 and realizes a sealed connection.

[0064] Specifically, the above-mentioned first seal 16 can be made of a material with certain elasticity, such as silica gel. And one side of the first seal 16 facing the fixing part 141 is configured to be in close contact with at least part of the surface of the fixing part 141. When the first seal 16 is connected to the fixing part 141, the first seal 16 can be in sealing cooperation with the fixing part 141.

[0065] Of course, a hole-like structure for the identification component 11 to pass through is also provided on the above-mentioned first seal 16, and the identification component 11 is inserted on the first seal 16 through the above-mentioned hole-like structure.

[0066] Please refer to Figure 5 , a second air guiding through hole 161 is formed on the above-mentioned first seal 16, and the second air guiding through hole 161 is used to connect the wake-up channel 142 and the intake trigger channel 21.

[0067] When the atomizer 20 is connected to the host 10 through the socket 131, the first seal 16 is located between the atomizer 20 and the fixing part 141 and the first seal 16 is in sealing connection with both the atomizer 20 and the fixing part 141. At this time, the wake-up channel 142 formed on the bracket 14 can be connected to the intake trigger channel 21 of the atomizer 20 only through the second air guiding through hole 161 provided on the first seal 16.

[0068] In some embodiments, at least one sealing protrusion 165 is provided on the outer periphery of the above-mentioned first seal 16 for interference fit with the inner wall of the housing 13.

[0069] In order to further improve the sealing effect between the first seal 16 and the atomizer 20, in some embodiments, please refer to Figure 5 , a sealing ring 162 is provided on the first seal 16. The sealing ring 162 is located on one side of the first seal 16 facing the socket 131 and is provided on the periphery of the second air guiding through hole 161. When the atomizer 20 is installed on the housing 13 through the socket 131, the sealing ring 162 abuts against the atomizer 20 to seal the atomizer 20.

[0070] Please refer to Figure 8 and Figure 10 , the above-mentioned sealing ring 162 protrudes relative to the upper surface of the first seal 16. When the atomizer 20 is installed on the housing 13 through the socket 131, one end of the atomizer 20 inserted into the housing 13 can be in contact with and pressed against the sealing ring 162, so as to achieve the sealing at the connection between the two. At this time, the above-mentioned structure of the sealing ring 162 can further reduce the possibility of the aerosol generated by the operation of the atomizer 20 entering the second air guiding through hole 161, and at the same time can also help to avoid the leakage of the aerosol matrix located in the atomizer 20 to the pressure sensor 15.

[0071] In order to further improve the blocking effect of the above-mentioned first seal 16 on aerosols, aerosol matrices, etc., in some embodiments, a liquid collecting groove 163 is concavely provided on one side of the first seal 16 facing away from the fixing portion 141, and the second air guiding through hole 161 penetrates through the liquid collecting groove 163 and protrudes relative to the bottom wall of the liquid collecting groove 163.

[0072] When there is leakage of the aerosol matrix or part of the aerosol enters the first seal 16 and condenses to form a liquid substance at the first seal 16, the above-mentioned liquid collecting groove 163 can be used to collect the aerosol matrix, liquid substances, etc. Since the end of the second air guiding through hole 161 facing the socket 131 is higher than the bottom wall of the liquid collecting groove 163, that is, it protrudes relative to the bottom wall of the liquid collecting groove 163, a certain amount of liquid substance collected in the liquid collecting groove 163 will not flow into the second air guiding through hole 161 and will not affect the normal operation of the second air guiding through hole 161. The setting of the structure of the above-mentioned liquid collecting groove 163 can further reduce the possibility of liquid impurities such as aerosol matrices contaminating and damaging the pressure sensor 15.

[0073] In other embodiments, it is also possible to set the orthographic projection of the second air guiding through hole 161 on the fixing portion 141 not to intersect or partially overlap with the orthographic projection of the first air guiding through hole 1411 on the fixing portion 141.

[0074] This structural design can make the structure of the wake-up channel 142 more tortuous, so as to reduce the possibility of impurities such as aerosols and aerosol matrices entering the pressure sensor 15, which helps to protect the pressure sensor 15.

[0075] In order to facilitate the installation of the atomizer 20 and enable the atomizer 20 to be used normally whether it is installed correctly or reversely, in some embodiments, two second air guiding through holes 161 are provided on the above-mentioned first seal 16, please refer to Figure 6 When the atomizer 20 is connected to the host 10 through the socket 131, the atomizer 20 can be hermetically connected to the first seal 16 and the air intake trigger channel 21 of the atomizer 20 can just communicate with one of the second air guiding through holes 161.

[0076] Specifically, the two second air guiding through holes 161 are symmetrically arranged at the center of the first seal 16.

[0077] Since the first seal 16 is hermetically connected to the fixing portion 141, in order to ensure that both of the two second air guiding through holes 161 can communicate with the wake-up channel 142, in some embodiments, a air guiding groove 164 is concavely provided on one side of the first seal 16 facing the fixing portion 141. The air guiding groove 164 communicates with all the second air guiding through holes 161 and communicates with the wake-up channel 142, please refer to Figure 6 .

[0078] The structure of the above-mentioned air guiding groove 164 is similar to a V shape, with both ends thereof respectively connected to the second air guiding through hole 161, and the middle part extending to the area opposite to the first air guiding through hole 1411 on the fixing part 141, so as to ensure that the second air guiding through hole 161 can be connected to the first air guiding through hole 1411 and the wake-up channel 142 through the air guiding groove 164.

[0079] Please refer to the two different air flow directions in the above-mentioned wake-up channel 142 Figure 8 and Figure 10 , Figure 8 . The arrows in [relevant reference] indicate the air flow direction. The air flow in the external environment can flow through the second air guiding through hole 161 on the first seal 16 to the air guiding groove 164, and flow into the wake-up channel 142 through the first air guiding through hole 1411, and then flow to the pressure sensor 15 through the wake-up channel 142.

[0080] It should be noted that the above-mentioned, the number of the sealing rings 162, the liquid collecting grooves 163 and the second air guiding through holes 161 are the same and arranged in one-to-one correspondence. Please refer to Figure 5 .

[0081] In order to further seal the wake-up channel 142 and protect the pressure sensor 15, in some embodiments, a second seal 17 for sealing the pressure sensor 15 is provided between the above-mentioned fixing part 141 and the pressure sensor 15. Please refer to Figure 8 . A third air guiding through hole 171 is provided on the second seal 17, and the third air guiding through hole 171 communicates the first air guiding through hole 1411 and the pressure sensor 15.

[0082] That is to say, the second seal 17 is sealingly connected to the side of the fixing part 141 facing away from the first seal 16, the pressure sensor 15 is sealingly arranged inside the second seal 17, and is connected to the first air guiding through hole 1411 of the fixing part 141 through the third air guiding through hole 171 provided at one end of the second seal 17. At this time, the first air guiding through hole 1411 and the third air guiding through hole 171 together form the above-mentioned wake-up channel 142.

[0083] Please refer to Figure 4 and Figure 8 . The second seal 17 is internally constructed with a chamber for accommodating the pressure sensor 15. The chamber is the same as the third air guiding through hole 171. The pressure sensor 15 located in the chamber can be connected to the air intake trigger channel 21 of the atomizer 20 through the third air guiding through hole 171, the first air guiding through hole 1411, the air guiding groove 164 and the second air guiding through hole 161 in sequence.

[0084] In some embodiments, the second seal 17 is made of silica gel material, and the second seal 17 is fixedly arranged on the side of the fixing part 141 facing away from the socket 131.

[0085] In order to further enhance the firmness of the connection between the atomizer 20 and the main unit 10, in some embodiments, it is provided that the main unit 10 further includes a plurality of magnetic members 143, and the atomizer 20 has a metallic material that can be adsorbed by the magnetic members 143, and can be detachably connected to the housing 13 through the socket 131 under the magnetic attraction of the magnetic members 143.

[0086] Specifically, the above-mentioned magnetic members 143 are arranged on the fixing part 141 and penetrate through the first sealing member 16. When the atomizer 20 is inserted through the socket 131 and abuts against the first sealing member 16, at this time, the atomizer 20 can squeeze the first sealing member 16 under the magnetic attraction of the magnetic members 143 and adhere to the magnetic members 143.

[0087] Specifically, please refer to Figure 4 , the number of the above-mentioned magnetic members 143 is four and they are distributed at the four corners of the fixing part 141.

[0088] In addition to the various structures described above, please refer to Figure 4 , in some embodiments, the main unit 10 further includes a battery cell 18, and the battery cell 18 is located inside the housing 13 and fixed on the bracket 14.

[0089] The above-mentioned battery cell 18 is used to supply power to components such as the controller 12, the identification component 11, and the atomizer 20.

[0090] It can be understood that the main unit 10 provided by the embodiments of the present application can not only realize the identification of the atomization power of different atomizers 20 and the adjustment of its own output power through the cooperation of the identification component 11 and the controller 12, but also meet the different requirements of different atomizers 20 for atomization power, making the main unit 10 have higher applicability; in addition, the main unit 10 can also, by adjusting its internal structure, make the wake-up channel 142 on the main unit 10 be independently arranged relative to the aerosol channel 22, which helps to reduce the possibility that the condensed aerosol matrix enters the wake-up channel 142 and damages the pressure sensor 15.

[0091] In a second aspect, embodiments of the present application provide an aerosol generating device 100, please refer to Figures 9-11 .

[0092] Specifically, the aerosol generating device 100 includes an atomizer 20 and the above-mentioned main unit 10. When the atomizer 20 is connected to the main unit 10, the cross-sectional structure of the aerosol generating device 100 is as shown in Figure 10 . At this time, the intake trigger channel 21 formed on the atomizer 20 is connected to the wake-up channel 142 formed on the bracket 14 through the first sealing member 16, and the aerosol channel 22 formed on the atomizer 20 remains independent of the above-mentioned channel, which can ensure that the aerosol generated when the atomizer 20 works does not flow to the pressure sensor 15.

[0093] It can be understood that the aerosol generating device 100 provided by the embodiments of the present application has the above-mentioned main body 10, and thus also includes any one or several of the above beneficial effects, which will not be elaborated herein.

[0094] The descriptions of the above embodiments tend to emphasize the differences between the embodiments, and their similarities can be referred to each other. For the sake of brevity, they will not be elaborated herein. The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
