[0002] An electronic atomization device is a device that can atomize an atomization matrix into an aerosol. An electronic atomization device usually includes a liquid storage structure, an atomizer, and a battery. The battery provides energy for the atomizer, and the atomizer atomizes the atomization matrix in the liquid storage structure to form an aerosol. At the same time, in order to expand the atomization matrix capacity in the atomizer, an additional oil storage device can be added to replenish the atomization matrix for the atomizer.

[0003] At present, the liquid inlet channel is arranged inside the aerosol generating device, and it is impossible to visually judge from the outside whether the liquid storage device is connected to the liquid inlet channel. Therefore, it is easy to have the problem that the liquid storage device is not activated and connected to the liquid inlet channel and is mistakenly judged as a malfunction of the aerosol generating device. Utility Model Content

[0004] Based on this, it is necessary to provide an electronic atomization device and an aerosol generating device to address the problem that the failure of the liquid storage device to activate and connect to the liquid inlet channel is misjudged as a failure of the aerosol generating device.

[0007] In one of the embodiments, the shell body is provided with an insertion port for inserting the liquid storage device into the shell body; the first end cover is integrated with the shell body, and the second end cover is detachably connected to the shell body to block the insertion port.

[0009] In one embodiment, when the activation structure is in the second position, the height difference between the suction nozzle and the pressing end is greater than a second height threshold, the second height threshold is between 12 mm and 14 mm, and the difference between the first height threshold and the second height threshold is between 4 mm and 6 mm; and / or, when the activation structure is in the second position, the height of the pressing end from the first end cap is between 1.5 mm and 3.5 mm.

[0010] In one embodiment, in the radial direction of the electronic atomization device, the maximum distance between the pressing end and the nozzle is between 4 mm and 7 mm.

[0011] In one embodiment, the activation structure includes a button, the shell includes a bracket, and the button passes through the bracket; the button is partially accommodated in the shell and slidably cooperates with the bracket, and the other part of the button is exposed from the shell to form the pressing end.

DETAILED DESCRIPTION

[0026] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0027] In the description of the present application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0028] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0029] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0030] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0031] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0032] The electronic atomization device in the traditional technology usually includes a cigarette cartridge and a cigarette rod. The capacity of the cigarette cartridge is small, and the cigarette cartridge needs to be replaced as a whole when replenishing the atomization matrix, which is costly. In order to solve the above problems, a liquid storage device for replenishing the atomization matrix has been developed. The liquid storage device is connected to the path of the liquid inlet channel of the electronic atomization device as a whole to replenish the atomization matrix. However, since the liquid storage device is an independent product, its liquid outlet is usually provided with a sealing film to seal the liquid outlet to prevent leakage during packaging and transportation. Therefore, it is usually necessary to remove the sealing film before installing the liquid storage device, which is complicated to operate. Alternatively, it is necessary to set a syringe capable of penetrating the sealing film in the electronic atomization device so as to pierce the sealing film with the syringe while installing the liquid storage device to absorb the atomization matrix. Taking the syringe capable of penetrating the sealing film in the electronic atomization device as an example, at this time, when installing the liquid storage device, it is necessary to align the liquid outlet with the syringe and press hard so that the syringe can penetrate the sealing film. However, during the process of applying force to install the liquid storage device, if the liquid storage device shakes or deviates, it may be difficult to smoothly connect to the liquid inlet channel, or the atomized matrix may leak, which makes the operation cumbersome. At the same time, such a design will also lead to a complex layout of the liquid inlet channel in the electronic atomization device. In order to solve the above problems, the present application proposes an aerosol generating device, combined with Figure 4 and Figure 5 The aerosol generating device comprises a housing 100, an atomizing assembly 300 and an activation structure 200, wherein a liquid storage device 400 can be installed on the housing 100. The activation structure 200 is movably arranged on the housing 100. When the liquid storage device 400 is installed in place, the activation structure 200 can be driven to move (along the Figure 5 K direction as shown), so that the activation structure 200 can be inserted into the liquid storage device 400 to achieve access to the liquid inlet channel. However, since the liquid storage device 400 and the activation structure 200 are internally connected, it is impossible to intuitively judge from the outside whether the activation structure 200 and the liquid storage device 400 are plugged in or not, so it is easy to have the problem that the user mistakenly believes that the aerosol generating device 10 has a fault when the activation structure 200 is not inserted into the liquid storage device 400 (i.e., not activated). In order to solve the above problem, the applicant further proposes an aerosol generating device, which also includes the shell 100, the atomization component 300 and the activation structure 200 as mentioned above, the shell 100 is provided with a suction nozzle 110, and the activation structure 200 is at a similar height position to the suction nozzle 110 when it is not activated, so that the user will touch the activation structure 200 at the same time when sucking through the suction nozzle 110, thereby reminding the user that the current aerosol generating device 10 is in an unactivated state, reducing the probability of the device being mistaken for a fault when it is not activated, and improving the user experience. The aerosol generating device 10 is described in detail below in conjunction with the drawings and specific implementation methods of the specification.

[0033] See also Figure 5, an embodiment of the present application provides an aerosol generating device 10, which includes an electronic atomization device and a liquid storage device 400. The liquid storage device 400 is used to store an atomization matrix. The liquid storage device 400 can be installed in the electronic atomization device to provide the atomization matrix to the electronic atomization device. The electronic atomization device has an activated state and an unactivated state. When in the unactivated state, the liquid storage device 400 is not connected to the liquid inlet channel in the electronic atomization device. At this time, the liquid storage device 400 cannot provide the atomization matrix to the electronic atomization device. When the electronic atomization device is in the activated state, the liquid storage device 400 can be connected to the liquid inlet channel in the electronic atomization device. At this time, the liquid storage device 400 can provide the atomization matrix to the electronic atomization device. The electronic atomization device is provided with an activation structure 200 as an identifier. The activation structure 200 can intuitively judge the activation state of the electronic atomization device in the aerosol generating device 10, reducing the probability that the electronic atomization device is considered to be a fault when it is in the unactivated state.

[0034] See also Figures 1 to 3 In one embodiment, the electronic atomization device includes a housing 100 and an activation structure 200. The housing 100 is provided with a nozzle 110 and a first end cover 120. The activation structure 200 is provided with a pressing end 210. The activation structure 200 is movably disposed in the housing 100 to move between a first position and a second position.

[0035] When the activation structure 200 is in the first position, at least part of the liquid inlet channel in the housing 100 is cut off. The pressing end 210 is exposed outside the housing 100, and the height H difference between the nozzle 110 and the pressing end 210 and the first end cover 120 is less than or equal to the first height threshold S1.

[0036] When the activation structure 200 is in the second position, the pressing end 210 is partially received in the housing 100 , the liquid inlet channel in the housing 100 is connected, and the height difference between the nozzle 110 and the pressing end 210 is greater than the first height threshold S1 .

[0037] In the above-mentioned electronic atomization device, the activation structure 200 is in the first position, that is, it is not yet activated, and at this time, the liquid inlet channel in the shell 100 is cut off. The activation structure 200 is in the second position, that is, it is activated, and at this time, at least part of the liquid inlet channel in the shell 100 is connected. When the activation structure 200 is in the first position, the difference in height H between the nozzle 110 and the pressing end 210 and the first end cover 120 is less than or equal to the first height threshold S1, that is, at this time, the pressing end 210 of the activation structure 200 and the nozzle 110 have a similar height position. When the user inhales, the activation structure 200 at a relatively high height position can prompt the user to activate the aerosol generating device 10. Thereby, the probability of the device not being activated being misjudged as a malfunction is reduced, and the user experience is improved. Please refer to Figures 2 to 6 , Figure 2 and Figure 5The electronic atomization device shown is in an unactivated state (ie, the activation structure 200 is in the first position). Figure 3 and Figure 6 The electronic atomization device shown is in an activated state (ie, the activation structure 200 is in the second position).

[0038] Furthermore, the first height threshold S1 can be flexibly adjusted so that when the nozzle 110 is in the first position and interacts with the suction part 20, the pressing end 210 can contact the suction part 20. The first height threshold S1 can be flexibly adjusted so that when the nozzle 110 is in the second position, the nozzle 110 can interact with the suction part 20 alone. Therefore, when the device is not activated, the contact sense generated by the pressing end 210 on the suction part 20 can remind the user that the aerosol generating device 10 is in an inactivated state, thereby reducing the probability of the inactivation of the device being misjudged as a fault and improving the user experience.

[0039] It is easy to understand that the user usually holds the nozzle 110 in the mouth to perform suction, that is, the suction part 20 refers to the mouth. Therefore, when the nozzle 110 interacts with the suction part 20, the pressing end 210 can contact the suction part 20, which means that when the mouth normally holds the nozzle 110, the cheek or lips will contact the pressing end 210. Figure 4 As shown, Figure 4 The outer contour of the suction site 20 when interacting with the suction nozzle 110 is shown.

[0040] Regarding the liquid inlet channel, the activation structure 200 can be used as one of the links of the liquid inlet channel, and the opening and closing of the liquid inlet channel can be controlled by controlling the position of the activation structure 200. Figure 5 and Figure 6 The following is a brief description of the positions and connections of the main components in the aerosol generating device 10 provided in one embodiment of the present application. It should be understood that the following description is not intended to limit the aerosol generating device 10, and that several modifications and improvements may be made without departing from the concept of the present application.

[0041] The aerosol generating device 10 provided in one embodiment of the present application further includes an atomizing assembly 300. The liquid storage device 400 and the atomizing assembly 300 are both disposed in the housing 100. The atomizing assembly 300 can convert the atomized matrix into an aerosol and output it from the nozzle 110. The activation structure 200 is movably disposed in the housing 100. When driven, it can be in a first position (such as Figure 5 ) and the second position (as shown Figure 6In addition, a liquid conducting cavity 130 is provided in the housing 100, and a side hole 220 is provided in the activation structure 200. At least when the activation structure 200 is in the second position, the side hole 220 can be connected to the atomization assembly 300 through the liquid conducting cavity 130. It is easy to understand that the liquid inlet channel described in each embodiment refers to the channel formed by the activation structure 200, the side hole 220 and the liquid conducting cavity 130 being connected to each other.

[0042] like Figure 5 When the activation structure 200 is in the first position, the activation structure 200 and the liquid storage device 400 are spaced apart. Therefore, the liquid inlet channel is cut off. The activation structure 200 does not extend into the liquid storage device 400, so it is impossible to obtain the atomized matrix from the liquid storage device 400. At this time, the aerosol generating device 10 cannot output aerosol to the outside, and there is a risk of being mistaken for a malfunction. Figure 6 When the activation structure 200 is in the second position, the activation structure 200 extends into the liquid storage device 400 and is in communication with the liquid storage device 400. Thus, the activation structure 200 can be used to connect the liquid storage device 400 and the atomization component 300, that is, the liquid inlet channel is in communication, and the activation structure 200 can obtain the atomized matrix and provide it to the atomization component 300 through the liquid guide cavity 130. Thus, the aerosol generating device 10 can output aerosols to the outside. When the activation structure 200 is in the second position, the approximate transmission path of the atomized matrix inside the aerosol generating device 10 is shown in FIG. Figure 6 The middle label is Q.

[0043] like Figure 7 In one embodiment, the activation structure 200 further includes a liquid suction end 230, which is disposed opposite to the pressing end 210. When the activation structure 200 is in the second position, that is, after activation, the liquid suction end 230 extends into the liquid storage device 400 to absorb the atomized matrix in the liquid storage device 400.

[0044] like Figure 2 In one embodiment, the first height threshold S1 is between 8 mm and 10 mm to prompt the user to activate the aerosol generating device 10. The first height threshold S1 can be set to 9.01 mm, 9.04 mm, 9.07 mm, 9.10 mm, 9.13 mm, 9.16 mm, 9.19 mm, etc., so as to facilitate the operation of the activation structure 200 to move to the second position when the user is prompted.

[0045] In order to enable the pressing end 210 of the activation structure 200 to contact the suction site 20 while the nozzle 110 interacts with the suction site 20 when the aerosol generating device 10 is in an unactivated state, the spacing between the nozzle 110 and the pressing end 210 can also be limited. Figure 2 and Figure 3For example, in one embodiment, the maximum distance S2 between the pressing end 210 and the nozzle 110 in the radial direction of the electronic atomization device may be between 4 mm and 7 mm. Figure 2 and Figure 3 , arrow R shows Figure 2 and Figure 3 Radial direction in the perspective shown.

[0046] Furthermore, in the radial direction of the electronic atomization device, the maximum distance S2 between the pressing end 210 and the nozzle 110 can be set to 4 mm, 4.3 mm, 4.6 mm, 4.9 mm, 5.2 mm, 5.5 mm, 5.8 mm, 6.1 mm, 6.4 mm, 6.7 mm and 7 mm, etc.

[0047] See also Figure 2 and Figure 3 In one embodiment, when the activation structure 200 is in the second position, a greater height difference can be provided between the nozzle 110 and the pressing end 210 to reduce the influence of the activation structure 200 in the activated electronic atomization device on the normal inhalation of the user.

[0048] When the activation structure 200 is in the second position, the height difference between the nozzle 110 and the pressing end 210 is greater than the second height threshold S3, and the second height threshold S3 is greater than the first height threshold S1. In other words, when the activation structure 200 is in the second position, the height position of the pressing end 210 is lower, so the influence of the activation structure 200 on the normal inhalation of the user in the activated electronic atomization device can be reduced. Furthermore, the difference between the first height threshold S1 and the second height threshold S3 can be set between 4 mm and 6 mm to reduce the influence of the activation structure 200 on the normal inhalation of the user in the activated electronic atomization device.

[0049] In one embodiment, the second height threshold S3 is between 12 mm and 14 mm. Figure 3 , the second height threshold S3 can be set to 12.16 mm, 12.32 mm, 12.48 mm, 12.64 mm, 12.80 mm, 12.96 mm, 13.12 mm, 13.28 mm, 13.44 mm, 13.60 mm, 13.76 mm, 13.92 mm and 14 mm. Generally speaking, the larger the second height threshold S3, that is, the lower the height position of the pressing end 210, the smaller the impact on normal suction. However, it should be noted that the larger the second height threshold S3, the larger the stroke required for the activation structure 200. Since the activation structure 200 is arranged in the housing 100, the stroke setting of the activation structure 200 will affect the layout of the components in the housing 100. Therefore, the second height threshold S3 can be set according to actual needs to reduce the impact on the layout of the internal components of the housing 100 while satisfying the normal suction of the electronic atomization device.

[0050] like Figure 2 and Figure 3 In one embodiment, the height H1 of the nozzle 110 from the first end cover 120 may be set to be between 15 mm and 17 mm. For example, the height H1 of the nozzle 110 from the first end cover 120 may be set to 15 mm, 15.55 mm, 16.10 mm, 16.65 mm or 17 mm.

[0051] The pressing end 210 of the activation structure 200 in the first position can be set to have a height H2 between 5.5 mm and 7.5 mm from the first end cap 120. For example, the height H2 between the pressing end 210 in the first position and the first end cap 120 can be set to 5.58 mm, 6 mm, 6.42 mm, 6.84 mm, 7 mm or 7.5 mm.

[0052] like Figure 2 and Figure 3 The pressing end 210 of the activation structure 200 in the second position may be set to have a height H3 between 1.5 mm and 3.5 mm from the first end cap 120. For example, the height H3 between the pressing end 210 in the second position and the first end cap 120 may be set to 1.72 mm, 2 mm, 2.28 mm, 2.56 mm, 3.12 mm or 3.5 mm.

[0053] See also Figure 5 and Figure 6 In one embodiment, the activation structure 200 includes a button 240 and a liquid guide tube 250. The liquid guide tube 250 is connected to the button 240, and the button 240 can drive the liquid guide tube 250 to move. The housing 100 also includes a second end cover 150, a bracket 160 and a housing body 170.

[0054] The button 240 passes through the bracket 160. The button 240 is partially received in the housing 100 and slidably cooperates with the bracket 160. The support provided by the bracket 160 and the button 240 facilitates the movement of the button 240 between the first position and the second position. Another part of the button 240 is exposed outside the housing 100 to form a pressing end 210, so that the button 240 can be driven to move from outside the housing 100.

[0055] like Figure 5 and Figure 6In one embodiment, the housing 100 is provided with a slide groove 101, the slide groove 101 has a first limiting surface 102 and a second limiting surface 103 disposed opposite to each other, and the activation structure 200 is slidably matched with the slide groove 101. The activation structure 200 is in a first position when it abuts against the first limiting surface 102, and is in a second position when it abuts against the second limiting surface 103. Thus, the activation structure 200 can be positioned by the first limiting surface 102 and the second limiting surface 103, so that the activation structure 200 can be accurately in the first position and the second position.

[0056] Further, the chute 101 can be arranged between the first end cover 120 and the bracket 160, for example, the first end cover 120 is sleeved on one side of the bracket 160, and the first end cover 120 and the bracket 160 are surrounded to form the chute 101. In this case, the first limiting surface 102 can be arranged on the first end cover 120, and the second limiting surface 103 can be arranged on the bracket 160. The first limiting surface can be the lower end surface of the first end cover 120, and the second limiting surface 103 can be the bottom wall of the chute 101. Of course, the first limiting surface 102 and the second limiting surface 103 can also be completely arranged on the bracket 160, and the same applies in this case.

[0057] Please continue reading Figure 6 and Figure 7 In one embodiment, the button 240 includes a cover 241 and an inserting tube 243. A stopper 242 is protruded from the outer periphery of the cover 241. The stopper 242 is used to abut against at least one of the stopper surfaces. For example, the stopper 242 can abut against the first stopper surface 102 of the first end cover 120, and the lower end surface of the cover 241 is used to abut against the second stopper surface 103 of the bracket 160.

[0058] The housing 100 further includes a sealing body 180, which is fixed to the bracket 160, and a cover shell 241 covers the outside of the sealing body 180. The outer peripheral side of the cover shell 241 is slidably matched with the bracket 160, and the inner peripheral side of the cover shell 241 is slidably matched with the sealing body 180. Thus, the bracket 160 is supported on the outside of the cover shell 241, and the sealing body 180 is supported on the inside of the cover shell 241, so that the position stability of the cover shell 241 can be improved. Furthermore, the plug-in tube 243 is arranged on the inner side of the cover shell 241, and the liquid guide tube 250 is fixedly plugged with the plug-in tube 243. Thus, when the button 240 is pressed, it can drive the liquid guide tube 250 to move synchronously.

[0059] In one embodiment, the liquid guide tube 250 is a section of the liquid inlet channel, and the side hole 220 is opened in the liquid guide tube 250. That is to say, the liquid inlet channel can be formed by the liquid guide tube 250, the side hole 220 and the liquid guide cavity 130 being connected in sequence. The liquid guide tube 250 is movably provided with the bracket 160 to make the liquid inlet channel open or cut off, that is, when the activation structure 200 is in the first position, the liquid guide tube 250 and the liquid storage device 400 are arranged at intervals, and the liquid inlet channel is cut off. When the activation structure 200 is in the second position, the liquid guide tube 250 extends into the liquid storage device 400, and the liquid inlet channel is open.

[0060] The sealing body 180 is at least partially attached to the outer periphery of the liquid guiding tube 250 to reduce leakage of the atomized matrix. The sealing body 180 is fixed to the bracket 160, and the liquid guiding tube 250, as a part of the activation structure 200, can move relative to the bracket 160. The sealing body 180 is sealed and attached to the outer periphery of the liquid guiding tube 250, which can reduce the probability of leakage of the atomized matrix at the liquid guiding tube 250.

[0061] Please continue reading Figure 6 In one embodiment, the liquid guiding cavity 130 is provided on the bracket 160, and the liquid guiding tube 250 is passed through the bracket 160 to extend into the liquid guiding cavity 130. Thus, when the liquid guiding tube 250 is extended into the liquid storage device 400, the liquid guiding tube 250 can connect the liquid guiding cavity 130 with the liquid storage device 400. Further, the bracket 160 is provided with an insert 161, one end of the liquid guiding tube 250 is passed through the inner side of the insert 161, and the other end of the liquid guiding tube 250 extends into the liquid guiding cavity 130. Part of the structure of the sealing body 180 is sleeved on the insert 161 to be fixed to the bracket 160. Another part of the structure of the sealing body 180 extends and fills between the insert 161 and the liquid guiding tube 250 to improve the sealing at the insert 161 and reduce the probability of leakage of the atomized matrix in the liquid guiding cavity 130.

[0062] Please continue reading Figure 6 In one embodiment, the second end cap 150 is opposite to the first end cap 120 in the length direction of the electronic atomization device, and the two ends of the shell body 170 are respectively connected to the first end cap 120 and the second end cap 150. The first end cap 120 and the shell body 170 are integrated to improve the stability of the overall structure, and the integrated arrangement of the two has a better overall appearance of the shell 100. The second end cap 150 can be integrated with the shell body 170 to improve the stability of the overall structure and the overall appearance of the shell 100; or, the second end cap 150 can also be detachably arranged with the shell body 170 to facilitate the installation or replacement of the liquid storage device 400.

[0063] Further, the liquid storage device 400 is disposed in the shell body 170, and the shell body 170 is provided with an insertion port 171 for the liquid storage device 400 to be inserted into the shell body 170. The second end cover 150 is detachably connected to the shell body 170 to block the insertion port 171. When the liquid storage device 400 needs to be installed, the second end cover 150 can be removed to open the insertion port 171. After the installation of the liquid storage device 400 is completed, the second end cover 150 can be reinstalled so that the liquid storage device 400 is stably located in the shell body 170.

[0064] Furthermore, the second end cap 150 can be supported on the bottom of the liquid storage device 400 to assist in fixing the liquid storage device 400. Furthermore, in the housing 170, the bracket 160 can be used together with the second end cap 150 to fix the liquid storage device 400.

[0065] In one embodiment, the first end cover 120 may be integrated with the suction nozzle 110; or, the suction nozzle 110 and the first end cover 120 may be separately configured.

[0066] See also Figure 1 , Figure 5 and Figure 6 In one embodiment, the side of the housing 100 facing away from the first end cap 120 is the bottom side 140, and the liquid storage device 400 is provided with a liquid outlet 410, and the liquid outlet 410 of the liquid storage device 400 faces the direction away from the bottom side 140. It should be noted that, for ease of use, when the aerosol generating device 10 is usually placed vertically, the first end cap 120 is the side relatively upward in the direction of gravity, and the bottom side 140 is the side relatively downward in the direction of gravity. That is to say, in this embodiment, the liquid outlet 410 faces upward in the direction of gravity.

[0067] It is understandable that if Figure 5 and Figure 6 When the aerosol generating device 10 is normally placed upright, the liquid outlet 410 of the liquid storage device 400 faces upward, and the activation structure 200 extends from top to bottom into the liquid storage device 400 for absorbing the atomized matrix. Therefore, if the aerosol generating device 10 is always stably maintained in an upright position, gravity will hinder the activation structure 200 from absorbing the atomized matrix. Therefore, in order to improve the efficiency of the activation structure 200 in absorbing the atomized matrix, in one embodiment, the side of the second end cap 150 facing away from the first end cap 120 is set as a tilting guide surface 151, and the tilting guide surface 151 is a curved surface. As a result, the aerosol generating device 10 has a tendency to lie down to at least one side, reducing the probability of the aerosol generating device 10 being maintained in a vertical position. When in a lying position, the liquid outlet 410 is no longer facing upward in the direction of gravity, and the direction in which the atomized matrix flows from the liquid storage device 400 into the activation structure 200 intersects with the direction of gravity, thereby relatively reducing the resistance of gravity to the activation structure 200 absorbing the atomized matrix and improving the smoothness of oil replenishment.

[0068] In one embodiment, the bottom side 140 can be completely tilted relative to the first end cover 120, so that when the bottom side 140 is in contact with a supporting surface (such as a desktop, etc.), the overall center of gravity of the aerosol generating device 10 is located outside the area defined by the bottom side 140, so that the aerosol generating device 10 has a lying movement tendency.

[0069] Alternatively, the bottom side 140 can be set as a unidirectional outward convex arc surface. At this time, since the bottom side 140 can only be in point contact or line contact with a plane such as a support surface, the bottom side 140 cannot form a stable support with a plane such as a support surface, so the aerosol generating device 10 has a tendency to lie down. In addition, in the direction of the normal line n pointing to the central area along the peripheral edge 152 of the second end cover 150, the tilt guide surface 151 gradually protrudes in the direction away from the first end cover 120. That is, from the peripheral edge 152 of the second end cover 150 from the outside to the inside, the second end cover 150 is in a shape that gradually protrudes outward, so that the aerosol generating device 10 has a tendency to lie down.

[0070] In one embodiment, the liquid storage device 400 is filled with a porous member, which is used to store and conduct the atomized matrix. It is understandable that the porous member can absorb and conduct the atomized matrix through capillary action to improve the conduction efficiency of the atomized matrix in the liquid storage device 400. Further, when the activation structure 200 is in the second position, the activation structure 200 contacts the porous member to absorb and conduct the atomized matrix to the atomization assembly 300. That is, when the activation structure 200 is in the second position, the liquid suction end 230 contacts the porous member. Further, the porous member can be configured as a cotton material or a ceramic material, etc.
