Description

Technical Field

[0001] The present application relates to the field of electronic atomization technology, and in particular to a shell assembly and an aerosol generating device. Background Art

[0002] An aerosol generating device is an electronic device that can atomize aerosol-forming substances such as tobacco oil and liquid medicine stored in it into aerosols through electric heating. Currently, aerosol generating devices on the market usually include structures such as an atomizer core, an electronic control component, and a liquid storage cup. Among them, the liquid storage cup generally stores aerosol-forming substances. The aerosol-forming substances in the liquid storage cup can be transferred to the atomizer core through capillary action and other methods. When the user uses the aerosol generating device for inhalation, the electronic control component provides electrical energy to the atomizer core, so that the atomizer core can be powered on and heated. The heat generated by the power supply and heating of the aerosol core can be used to atomize the aerosol-forming substances transferred to the atomizer core into an aerosol that can be inhaled by the user.

[0003] With the continuous use of the aerosol generating device, the power of the aerosol generating device and the amount of aerosol-forming substances will gradually decrease. In order to facilitate the user to know the remaining power of the aerosol generating device and the remaining amount of aerosol-forming substances at any time and intuitively, the aerosol generating device is usually equipped with a display component that can display visual information such as the remaining power and the remaining amount of aerosol-forming substances. The type of the display component can be an inflexible rigid display component (such as a digital tube, etc.) or a flexible flexible display component (such as a flexible OLED screen, a flexible AMOLED screen, a flexible LCD screen, etc.). Compared with the rigid display component, the flexible display component can bend and thus can simultaneously cover multiple outer walls at different positions in the aerosol generating device (such as covering the front side wall, the left side wall and the rear side wall of the aerosol generating device at the same time), so that the aerosol generating device can obtain a larger information display range and can display more visual information to the user. Therefore, the application of flexible display components in the field of electronic atomization technology is gradually becoming a trend.

[0004] In the related art, when a sheet-shaped flexible display component is applied to an aerosol generating device, the flexible component is usually installed on the shell of the aerosol generating device (that is, the shell serves as the installation carrier of the flexible display component). However, different product manufacturers have different requirements for the location installation of the flexible display component (it can be understood here that for different location installation requirements, the required length of the flexible display component is usually different). For example, some manufacturers need the flexible display component to cover the front side wall and the left side wall of the shell at the same time, some manufacturers need the flexible display component to cover the rear side wall and the right side wall of the shell at the same time, and some manufacturers need the flexible display component to cover the front side wall, the right side wall and the rear side wall of the shell at the same time, and so on. Therefore, when component suppliers face product manufacturers with different requirements, they usually need to design shells of different structural types. That is, a shell of one structural type can usually only adapt to a flexible display component of one length and a type of location installation requirement. Therefore, in the related art, the shell structure applied to the aerosol generating device has technical problems of poor installation adaptability (that is, it cannot adapt to the installation of flexible display components of different lengths) and poor installation flexibility (that is, the installation position of the flexible display component cannot be flexibly adjusted).

[0069] Please refer to Figure 1-11In one embodiment of the present application, a shell assembly applicable to an aerosol generating device is provided. The shell assembly includes a top cover 2, a bottom cover 3, and a hollow through-body shell 1. The body shell 1 has a first end 11 and a second end 12 relative to each other along its own height direction. The top cover 2 is fixedly matched with the first end 11, and the bottom cover 3 is fixedly matched with the second end 12. The bottom cover 3, the top cover 2, and the body shell 1 jointly define a mounting groove 10 for mounting a flexible display assembly 8. The mounting groove 10 is located between the top cover 2 and the bottom cover 3 and is arranged 360 degrees around the body shell 1. It should be noted here that, for example, the height direction of the body shell 1 is Figure 1 、 Figure 2 and Figure 4 The up and down directions in .

[0070] In this embodiment, it should be noted that, in specific implementations, the top cover 2 and the first end portion 11 of the body shell 1 may be fixedly engaged by means of an interference fit, a snap-fit ​​connection, a threaded engagement, or the like. This method may be determined based on actual needs, and this embodiment does not specifically limit the method for fixing the top cover 2 and the body shell 1. Similarly, the bottom cover 3 and the second end portion 12 of the body shell 1 may be fixedly engaged by means of an interference fit, a snap-fit ​​connection, a threaded engagement, or the like. This method may be determined based on actual needs, and this embodiment does not specifically limit the method for fixing the bottom cover 3 and the body shell 1.

[0071] In this embodiment, based on the above-mentioned structural design, the top cover 2, the body shell 1, and the bottom cover 3 are assembled into one body to jointly define an installation groove 10. Since the installation groove 10 is arranged 360 degrees around the body shell 1 along the circumference of the body shell, it is possible to provide sufficient and flexible installation space for the flexible display component 8 when the flexible display component 8 is installed along the circumference of the shell component. Therefore, the shell component provided in this embodiment can not only adapt to the installation of flexible display components 8 of different lengths, but also can flexibly adjust the installation position of the flexible display component 8 according to actual installation requirements.

[0072] For example, assuming that the body shell 1 has four outer walls with different orientations, namely the front side wall, the rear side wall, the left side wall and the right side wall, and currently it is necessary to install a flexible display component 8 with a certain length in the installation slot 10 of the shell component, and the length of the flexible component is sufficient to cover any three of the four outer walls at the same time, then when installing the flexible display component 8 in the shell component provided by this embodiment, you can choose to set the flexible display component 8 to cover the front side wall, the left side wall and the rear side wall of the body shell 1 at the same time, or you can choose to set the flexible display component 8 to cover the front side wall, the right side wall and the rear side wall of the body shell 1 at the same time, or you can choose to set the flexible display component 8 to cover the front side wall, the left side wall and the right side wall of the body shell 1 at the same time, so that the installation position of the flexible display component 8 can be flexibly adjusted according to actual installation requirements. Even if the position installation requirements of the flexible display component 8 change temporarily, there is no need to replace the shell structure.

[0073] For another example, suppose that there are currently two flexible display components 8 of different lengths (defined as a first display component and a second display component respectively), the length of the first display component is sufficient to cover the four outer walls of the body shell 1 at the same time, and the length of the second display component can only cover any three of the four outer walls of the body shell 1 at the same time, then when it is necessary to install the first display component with a longer length on the shell component provided by this embodiment, the flexible display component 8 can be set to cover the front side wall, rear side wall, left side wall and right side wall of the body shell 1 at the same time, and when it is necessary to install the second display component with a shorter length on the shell component provided by this embodiment, the flexible display component 8 can be set to cover any three of the four outer walls of the body shell 1 at the same time, that is, the first display component and the second display component of different lengths can be installed in the installation slot 10 of the shell component, so the shell component provided by this embodiment is compatible with the installation of flexible display components 8 of different lengths.

[0074] Furthermore, in some optional embodiments of the present application, the top cover 2 and the first end portion 11 of the body shell 1 can be fixedly matched by a snap connection. For details, please refer to Figure 2 、 Figure 4-5 and Figure 7 The inner circumferential wall of the top cover 2 is provided with a first snap 23, and the side wall of the first end portion 11 is provided with a first snap hole 110. The top cover 2 is sleeved on the outer wall of the first end portion 11, and the first snap 23 is snapped into the first snap hole 110, thereby firmly snapping the top cover 2 and the body shell 1 together. In a specific implementation, the number of first snaps 23 and first snap holes 110 provided can be determined according to actual needs and can be one or more, and this embodiment does not impose any specific limitations on this.

[0075] Similarly, in some optional embodiments of the present application, the bottom cover 3 and the second end 12 of the body shell 1 can also be fixedly matched by a snap connection. For details, please refer to Figure 2 、 Figure 4-5 and Figure 8 The inner circumferential wall of the bottom cover 3 is provided with a second latch 33, and the side wall of the second end portion 12 is provided with a second latch hole 120. The bottom cover 3 is sleeved on the outer wall of the second end portion 12, and the second latch 33 is engaged with the second latch hole 120, thereby firmly securing the bottom cover 3 and the body shell 1 together. In a specific implementation, the number of second latches 33 and second latch holes 120 provided can be determined based on actual needs and can be one or more, and this embodiment does not impose any specific limitations on this.

[0076] Furthermore, if Figure 9-10 and Figure 12-13 As shown, considering that in some specific application scenarios where the shell assembly is applied to the aerosol generating device, in order to avoid the flexible display assembly 8 being exposed and reducing the overall aesthetic appearance of the aerosol generating device, it is usually necessary to install a hollow through-hole protective shell 9 made of a light-transmitting material between the top cover 2 and the bottom cover 3 to surround the flexible display assembly 8. At the same time, considering that during the installation of the protective shell 9 and after the installation of the protective shell 9 is completed, the protective shell 9 may move along the left and right direction or the front and back direction of the shell assembly under the action of external force, and when the amplitude of the movement of the protective shell 9 is too large, the inner wall of the protective shell 9 may cause strong squeezing of the flexible display assembly 8, thereby causing local damage to the flexible display assembly 8. Based on these considerations, in order to reduce the risk of local damage to the flexible display assembly 8 during the installation of the protective shell 9 and after the installation of the protective shell 9 is completed, the shell assembly can be further structurally optimized, as follows:

[0077] Please refer to Figure 4-8 as well as Figure 12-15In some optional embodiments of the present application, the top cover 2 includes a first annular inner cover 21 and a first outer cover 22 with a top end surface 221, one end of the first annular inner cover 21 is connected to the inner wall of the first outer cover 22 as a whole, and the other end protrudes from the interior of the first outer cover 22 in a direction away from the top end surface 221, the first clip 23 is provided on the inner circumferential wall of the first annular inner cover 21, and the first annular inner cover 21 is sleeved on the outer wall of the first end portion 11; moreover, the bottom cover 3 includes a second annular inner cover 31 and a second outer cover 32 with a bottom end surface 321, one end of the second annular inner cover 31 is connected to the inner wall of the second outer cover 32 as a whole, and the other end protrudes from the interior of the second outer cover 32 in a direction away from the bottom end surface 321, the second clip 33 is provided on the inner circumferential wall of the second annular inner cover 31, and the second annular inner cover 31 is sleeved on the outer wall of the second end portion 12. With such an arrangement, in some specific application scenarios where the shell assembly is applied to an aerosol generating device, when installing the protective shell 9, the upper end of the protective shell 9 can be sleeved on the outer peripheral wall of the first annular inner cover 21, and the lower end can be sleeved on the outer peripheral wall of the second annular inner cover 31. On the one hand, the first annular inner cover 21 can limit the upper end of the protective shell 9, so that even if the upper end of the protective shell 9 is subjected to external force, it is difficult for the upper end of the protective shell 9 to move significantly. On the other hand, the second annular inner cover 31 can limit the lower end of the protective shell 9, so that even if the lower end of the protective shell 9 is subjected to external force, it is difficult for the lower end of the protective shell 9 to move significantly. In these two aspects, the protective shell 9 as a whole is difficult to move along the left and right directions or the front and back directions of the shell assembly, thereby effectively reducing the risk of strong squeezing of the flexible display assembly 8 due to excessive movement of the protective shell 9 and causing local damage to the flexible display assembly 8 during and after the installation of the protective shell 9.

[0078] Furthermore, in some specific application scenarios where the housing assembly is applied to an aerosol generating device, in order to better limit the upper and lower ends of the protective shell 9, the top cover 2, the bottom cover 3 and the protective shell 9 may be structurally designed as follows:

[0079] For details, please refer to Figure 4-8 as well as Figure 12-15There is a gap between the inner circumferential wall of the end of the first outer cover portion 22 away from the top end surface 221 and the outer circumferential wall of the first annular inner cover portion 21, and a circle of first grooves 20 are formed. There is a gap between the inner circumferential wall of the end of the second outer cover portion 32 away from the bottom end surface 321 and the outer circumferential wall of the second annular inner cover portion 31, and a circle of second grooves 30 are formed. Correspondingly, the end surface of the protective shell 9 close to the top cover 2 is convexly provided with a first edge protrusion 91 that is adapted to the first groove 20, and the first edge protrusion 91 is connected to the inner wall of the protective shell 9 as a whole. The end surface of the protective shell 9 close to the bottom cover 3 is convexly provided with a first edge protrusion 91 that is adapted to the second groove 30, and the second edge protrusion 92 is connected to the inner wall of the protective shell 9 as a whole.

[0080] With such an arrangement, in some specific application scenarios where the shell assembly is applied to an aerosol generating device, when installing the protective shell 9, on the one hand, the upper end of the protective shell 9 can be sleeved on the outer peripheral wall of the first annular inner cover 21 and the first edge protrusion 91 can be inserted into the first groove 20. In this way, under the limiting action of the first groove 20, the upper end of the protective shell 9 will be more difficult to move; on the other hand, the lower end of the protective shell 9 can be sleeved on the outer peripheral wall of the second annular inner cover 31 and the second edge protrusion 92 can be inserted into the second groove 30. In this way, under the limiting action of the second groove 30, the lower end of the protective shell 9 will be more difficult to move. In these two aspects, the protective shell 9 as a whole will be more difficult to move along the left and right direction or the front and back direction of the shell assembly.

[0081] Further, please refer to Figure 4-5 and Figure 7 In some optional embodiments of the present application, the first annular inner cover 21 has a first edge portion 211 and a second edge portion 212 spaced apart from each other. The inner walls of the first edge portion 211 and the second edge portion 212 are each provided with at least one first latch 23. The sidewall of the first end portion 11 is provided with at least two first latch holes 110, with each first latch 23 correspondingly engaging with each first latch hole 110. This arrangement, by increasing the number of first latches 23 and first latch holes 110 and optimizing their positional layout, facilitates a more secure fastening between the top cover 2 and the body shell 1, preventing them from separating.

[0082] Similarly, see Figure 4 、 Figure 6 and Figure 8In some optional embodiments of the present application, the second annular inner cover portion 31 has a third edge portion 311 and a fourth edge portion 312 spaced apart from each other. The inner walls of the third edge portion 311 and the inner walls of the fourth edge portion 312 are each provided with at least one second latch 33. The sidewall of the second end portion 12 is provided with at least two second latch holes 120, with each second latch 33 correspondingly engaging with each second latch hole 120. This arrangement, by increasing the number of second latches 33 and second latch holes 120 and optimizing their positional layout, facilitates a more secure fastening between the bottom cover 3 and the body shell 1, preventing them from separating.

[0083] Further, please refer to Figure 2 as well as Figure 4-5 In some optional embodiments of the present application, along the height direction of the shell assembly, each first clip 23 has a first limiting wall 232 and a first guide wall 231 that are arranged back to back to each other, and the first limiting wall 232 is closer to the top end surface 221 than the first guide wall 231. The first limiting wall 232 and the first guide wall 231 are both connected to the inner wall of the first annular inner cover 21 as a whole, and the angle between the first limiting wall 232 and the inner wall of the first annular inner cover 21 is a right angle or an acute angle, and the angle between the first guide wall 231 and the inner wall of the first annular inner cover 21 is an obtuse angle. With such arrangement, in the process of assembling the top cover 2 and the first end portion 11 of the body shell 1 together by means of a snap connection, on the one hand, when the first end portion 11 of the body shell 1 presses the first guide wall surface 231 of the first snap 23 with a certain force, since the angle between the first guide wall surface 231 and the inner wall of the first annular inner cover 21 is an obtuse angle, the first guide wall surface 231 can guide the first end portion 11 of the body shell 1, so that the first guide wall surface 231 and the first end portion 11 of the body shell 1 can slide relative to each other more easily, thereby making it easier for the first snap 23 to be snapped into the first snap 23. The first retaining wall 232 is in the hole 110, that is, it is conducive to making the top cover 2 and the body shell 1 more easily buckled together; on the other hand, after the first retaining wall 23 is inserted into the first retaining hole 110, since the angle between the first limiting wall 232 and the inner wall of the first annular inner cover 21 is a right angle or an acute angle, the first limiting wall 232 can better abut against the hole wall of the first retaining hole 110 without sliding relative to each other, so that after the first retaining wall 23 is inserted into the first retaining hole 110, it is difficult to come out of the first retaining hole 110, that is, it is conducive to making the top cover 2 and the body shell 1 more firmly buckled together.

[0084] Similarly, see Figure 2 、 Figure 4 、 Figure 6 and Figure 8In some optional embodiments of the present application, along the height direction of the shell assembly, each second clip 33 has a second limiting wall 332 and a second guide wall 331 that are arranged back to back with each other. The second limiting wall 332 is closer to the bottom end face 321 than the second guide wall 331. The second limiting wall 332 and the second guide wall 331 are both connected to the inner wall of the second annular inner cover portion 31 as a whole. The angle between the second limiting wall 332 and the inner wall of the second annular inner cover portion 31 is a right angle or an acute angle, and the angle between the second guide wall 331 and the inner wall of the second annular inner cover portion 31 is an obtuse angle. With such an arrangement, in the process of assembling the bottom cover 3 and the second end 12 of the body shell 1 together by means of a snap connection, on the one hand, it is conducive to making the bottom cover 3 and the body shell 1 able to be snapped together more easily; on the other hand, it is conducive to making the bottom cover 3 and the body shell 1 able to be snapped together more firmly. It should be noted here that the structural principle of this embodiment is similar to that of the aforementioned related embodiments (i.e., Figure 2 、 Figure 4-5 The structural principle of the embodiment shown in the figure is similar and will not be repeated here.

[0085] Further, please refer to Figure 4-5 and Figure 7 In some optional embodiments of the present application, the top cover 2 is made of hard plastic (in a specific embodiment, the top cover 2 can be integrally injection molded). Two first notches 2110 are defined on the first edge portion 211, and two second notches 2120 are defined on the second edge portion 212. A first latch 23 is defined between the two first notches 2110, and a first latch 23 is defined between the two second notches 2120. With this arrangement, when the top cover 2 and the first end portion 11 of the body shell 1 are assembled together via a snap connection, the portions of the first edge portion 211 where the first latch 23 is defined and the portions of the second edge portion 212 where the first latch 23 is defined can more easily undergo elastic deformation when pressed by the first end portion 11 of the body shell 1, thereby making it easier for the two first latches 23 to snap into the two first latch holes 110. This further facilitates the snap connection between the top cover 2 and the body shell 1.

[0086] Similarly, see Figure 4 、 Figure 6 and Figure 8In some optional embodiments of the present application, the bottom cover 3 is made of hard plastic (in a specific embodiment, the bottom cover 3 can be integrally injection molded). The third edge portion 311 defines two spaced-apart third notches 3110, and the fourth edge portion 312 defines two spaced-apart fourth notches 3120. A second latch 33 is disposed between the two third notches 3110, and a second latch 33 is disposed between the two fourth notches 3120. With this arrangement, when the bottom cover 3 and the second end portion 12 of the body shell 1 are assembled together via a snap connection, the portions of the third edge portion 311 where the second latch 33 is disposed and the portions of the fourth edge portion 312 where the second latch 33 is disposed are more easily elastically deformed when pressed by the second end portion 12 of the body shell 1, thereby enabling the two second latches 33 to more easily engage with the two second latch holes 120. This facilitates further facilitating the snap connection between the bottom cover 3 and the body shell 1.

[0087] Furthermore, the applicant has implemented the relevant embodiments of this application (including at least Figure 1-6 During the process of manufacturing the housing assembly (shown in the embodiment shown in FIG), it was found that if the housing assembly is manufactured by the method of “first integrally forming the top cover 2 and the body shell 1 by injection molding, and then assembling the bottom cover 3 and the body shell 1 together by snap connection”, or if the housing assembly is manufactured by the method of “first integrally forming the bottom cover 3 and the body shell 1 by injection molding, and then assembling the top cover 2 and the body shell 1 together by snap connection”, the following problems will occur:

[0088] First, during the process of integrally forming the top cover 2 and the body shell 1 or the bottom cover 3 and the body shell 1 by injection molding, there will be a problem of difficulty in demoulding, which will lead to a high scrap rate and increase the production cost of the shell assembly;

[0089] Second, the plastic body shell 1 lacks structural strength, which reduces the drop resistance of the aerosol generating device when the resulting housing assembly is used in the device. This makes the device prone to falling apart when dropped.

[0090] Third, in some application scenarios of manufacturing aerosol generating devices, since only one end of the body shell 1 is open, it is not convenient to flexibly assemble other components of the aerosol generating device (such as the atomizing core 61, the liquid storage cup 5, the electronic control component 7, etc.) inside the shell assembly, thereby reducing the assembly convenience of the aerosol generating device.

[0091] Based on the above findings, in some optional embodiments of the present application, the body shell 1 is made of metal, and the top cover 2 and bottom cover 3 are both made of hard plastic. With this arrangement, firstly, compared to a one-piece structure in which the top cover 2 and body shell 1 are integrally formed, or compared to a one-piece structure in which the bottom cover 3 and body shell 1 are integrally formed, the structure of a single top cover 2, a single bottom cover 3, and a single body shell 1 is simpler and smaller in size. Therefore, when the top cover 2 or the bottom cover 3 is molded by injection molding, or when the body shell 1 is molded by die casting or other methods, demolding difficulties will not occur, thereby facilitating an improvement in the yield rate of components and, in turn, reducing the production cost of the housing assembly.

[0092] Secondly, compared to a body shell 1 made of plastic, a body shell 1 made of metal has higher structural strength and is less likely to be squeezed and deformed when dropped. Therefore, even if the body shell 1 and the top cover 2 or the bottom cover 3 are fixed together by a snap connection, the corresponding snaps are not likely to come out of the corresponding snap holes. Therefore, when the housing assembly provided in this embodiment is applied to an aerosol generating device, the overall anti-drop performance of the aerosol generating device can be effectively improved, making it less likely for the aerosol generating device to "fall apart" when dropped.

[0093] Thirdly, the top cover 2 and the body shell 1, as well as the bottom cover 3 and the body shell 1, are fixed together by a fixed-fit assembly method, so that the shell assembly can have a high degree of assemblability. In some application scenarios of making aerosol generating devices, since the two ends of the body shell 1 are open before the body shell 1 is respectively assembled with the bottom cover 3 and the top cover 2 into a shell assembly, it is convenient to flexibly install other components of the aerosol generating device inside the shell assembly, thereby improving the assembly convenience of the aerosol generating device.

[0094] In this embodiment, it should be noted that, in specific implementation, the material of the body shell 1 can be a metal material with a certain structural strength, such as iron, aluminum, aluminum alloy, zinc alloy, titanium alloy, stainless steel, magnesium alloy, etc., the material of the top cover 2 can be a plastic with a certain hardness, such as polycarbonate, polyformaldehyde, polypropylene, polyetherimide, ABS plastic, PCTG plastic, etc., and the material of the bottom cover 3 can be a plastic with a certain hardness, such as polycarbonate, polyformaldehyde, polypropylene, polyetherimide, ABS plastic, PCTG plastic, etc., as long as it can meet the use requirements, this embodiment does not impose any specific restrictions on the specific materials of the body shell 1, top cover 2 and bottom cover 3.

[0095] Further, please refer to Figure 1 and Figure 12In some optional embodiments of the present application, a lanyard hole 220 is provided on the outer wall of the top cover 2. This arrangement allows the user to conveniently attach a lanyard to the lanyard hole 220, thereby improving the portability of the aerosol generating device after the housing assembly provided by this embodiment is applied to the aerosol generating device.

[0096] Further, please refer to Figure 7 and Figure 13 In some optional embodiments of the present application, a raised portion 24 is provided on the inner wall of the top cover 2 on the side facing away from the top end surface 221. The raised portion 24 is hollow, forming a cavity 240 that communicates with the lanyard hole 220. The cavity 240 can be used to accommodate a plug 62 such as a silicone plug or a rubber plug. With this arrangement, in some applications where the housing assembly provided by this embodiment is used in an aerosol generating device, the plug 62 can be inserted into the cavity 240 to obscure the lanyard hole 220, preventing the user from observing the interior of the housing assembly through the lanyard hole 220 and affecting the user's visual experience.

[0097] Furthermore, in some application scenarios where the housing assembly is applied to an aerosol generating device, in order to enable the flexible display assembly 8 to be quickly and neatly wrapped around the outer wall of the body shell 1 during the assembly process of the aerosol generating device, the body shell 1 and the flexible display assembly 8 may be structurally designed as follows:

[0098] For details, please refer to Figure 1-2 、 Figure 11 as well as Figure 16In some optional embodiments of the present application, a first slit 111 is provided on the side wall of the first end portion 11, and the first slit 111 passes through the end surface of the first end portion 11; a second slit 121 is provided on the side wall of the second end portion 12, and the second slit 121 passes through the end surface of the second end portion 12; the first slit 111 and the second slit 121 are located on the same side of the body shell 1 (optionally, the first slit 111 and the second slit 121 are located in the same straight line direction); accordingly, a positioning hole 80 is provided on each of the two side edges of the flexible display component 8 along its own width direction. With such a configuration, in some application scenarios in which an aerosol generating device including a flexible display component 8 is assembled, when installing the flexible display component 8, in some optional embodiments, one of the positioning holes 80 of the flexible display component 8 can be aligned with the first slit 111 and the other positioning hole 80 can be aligned with the second slit 121, and then the other parts of the flexible display component 8 can be adhered to the body shell 1, so that the flexible display component 8 can be quickly and neatly wrapped around the outer wall of the body shell 1. In other optional embodiments, a specially designed installation jig can also be used to position and install the flexible display component 8. Specifically, the installation jig has two positioning pins. When installing the flexible display component 8, one of the positioning pins can be placed in the first slit 111 and one end of the positioning pin is exposed, and the other positioning pin is placed in the second slit 121 and one end of the positioning pin is exposed. Then, one of the positioning holes 80 of the flexible display component 8 is aligned with the first slit 111 and the corresponding positioning pin passes through the positioning hole 80, and the other positioning hole 80 is aligned with the second slit 121 and the corresponding positioning pin passes through the corresponding positioning hole 80. In this way, under the limiting action of the two positioning pins, the flexible display component 8 is difficult to move along the height direction of the body shell 1, and it is difficult to move along the circumference of the body shell 1, so that the flexible display component 8 can be quickly and neatly wrapped around the outer wall of the body shell 1.

[0099] Furthermore, considering that in some application scenarios in which an aerosol generating device including a flexible display component 8 is to be assembled, the flexible display component 8 usually has a tail portion 81, and a connector 82 for connecting a flexible flat cable is provided on the surface of the tail portion 81. By electrically connecting the two ends of the flexible flat cable to the connector 82 and the electronic control component 7 of the aerosol generating device respectively, the electrical connection between the flexible display component 8 and the electronic control component 7 can be achieved, so that the electronic control component 7 controls the flexible display component 8 to display visual information. Based on this consideration, in order to facilitate the electrical connection of the flexible display component 8 located on the outside of the body shell 1 with the electronic control component 7 located on the inside of the body shell 1 through a flexible flat cable in some application scenarios in which an aerosol generating device including a flexible display component 8 is to be assembled, such as Figure 4 and Figure 9-10As shown, in some optional embodiments of the present application, a reserved through hole 13 is opened on the side wall of the body shell 1, and the reserved through hole 13 can be used for the flexible cable to pass through.

[0100] Correspondingly, please refer to Figure 12-16 The embodiment of the present application also provides an aerosol generating device, which includes a mouthpiece 4, a liquid storage cup 5, an atomizing core 61, an electronic control component 7 and a housing component in any of the above embodiments (such as Figure 1-9 shown), where:

[0101] The suction nozzle 4 is connected to the top surface 221 of the top cover 2. In some optional embodiments, the suction nozzle 4 can be connected to the top surface 221 of the top cover 2 by an assembly method such as a snap connection or a threaded connection. In other optional embodiments, the suction nozzle 4 can also be integrally injection molded with the top cover 2 by an injection molding method. This embodiment does not impose specific limitations on this.

[0102] The liquid storage cup 5 is mounted inside the housing assembly. An airflow channel 52 and a storage cavity 51 for storing aerosol-forming substances are provided inside the liquid storage cup 5. One end of the airflow channel 52 is connected to the mouthpiece 4, and the other end is connected to the outside. Specifically, an air inlet hole 320 is formed on the bottom end surface 321 of the bottom cover 3, and the other end of the airflow channel 52 is connected to the outside through the air inlet hole 320.

[0103] The atomizer core 61 is installed in the airflow channel 52 so that the aerosol generated by the atomizer core 61 can be carried away by the suction airflow formed in the airflow channel 52 and discharged to the mouthpiece 4 for inhalation by the user. In addition, the atomizer core 61 is connected to the storage chamber 51 so that the atomizer core 61 can absorb the aerosol-forming substance from the storage chamber 51 for heating and atomization.

[0104] The electronic control assembly 7 is installed inside the housing assembly and is electrically connected to the atomizer core 61. Specifically, the electronic control assembly 7 includes a battery 71 and a control circuit board 72. The control circuit board 72 is electrically connected to the battery 71 and the atomizer core 61 respectively.

[0105] In this embodiment, based on the above-mentioned structural design, when the user bites the mouthpiece 4 to inhale, an inhalation airflow will be formed in the airflow channel 52. At the same time, the control circuit board 72 of the electronic control component 7 will control the atomization core 61 to be energized and heated, thereby atomizing the aerosol-forming substance inhaled by itself into an aerosol. The aerosol is finally discharged to the mouthpiece 4 along with the inhalation airflow for the user to inhale.

[0106] In this embodiment, it should be noted that, thanks to the improvement of the above-mentioned shell assembly, the aerosol generating device provided by this embodiment has the same technical effect as the above-mentioned shell assembly, which will not be repeated here.

[0107] Further, please refer to Figure 10-11 as well as Figure 13-16 In some optional embodiments of the present application, the aerosol generating device further includes a flexible display component 8 for displaying visual information. The flexible display component 8 is installed in the installation groove 10 and can be electrically connected to the control circuit board 72 of the electronic control component 7 through a flexible flat cable. Moreover, the flexible display component 8 can be fixed to the body shell 1 by gluing and covers at least two outer side walls of the body shell 1 at different positions along its own circumference. The light-emitting surface 83 of the flexible display component 8 is arranged to face away from the body shell 1.

[0108] Further, please refer to Figure 13 In some optional embodiments of the present application, in order to reduce the risk of dry burning and leakage of the aerosol generating device, a liquid storage cotton 53 can be set in the storage cavity 51 of the liquid storage cup 5.

[0109] Further, please refer to Figure 12-16 In some optional embodiments of the present application, the aerosol generating device also includes a protective shell 9 made of a light-transmitting material (such as acrylic, glass, polycarbonate, etc.), the protective shell 9 is hollow and through, and the protective shell 9 is clamped between the top cover 2 and the bottom cover 3 and surrounds the flexible display component 8.

[0110] In this embodiment, the provision of the protective shell 9 can not only ensure that the user can observe the visual information displayed by the flexible display component 8 through the protective shell 9, but also protect the flexible display component 8 to prevent the flexible display component 8 from being damaged by the impact of foreign objects, and can also avoid the flexible display component 8 being exposed and affecting the overall appearance of the aerosol generating device.

[0111] In this embodiment, it should be noted that, in some optional implementations, the aerosol generating device including the protective shell 9 and the flexible display assembly 8 can be obtained by the following assembly method:

[0112] For details, please refer to Figure 12-16First, the relevant components including the control circuit board 72 (for the convenience of explanation, referred to as the control module) can be installed in the bottom cover 3, and the flexible display component 8 can be fixedly wrapped around the outer wall of the body shell 1 along the circumference of the body shell 1; then, the bottom of the liquid storage cup 5 containing the atomizer core 61 and the liquid storage cotton 53 is assembled with the control module, and the electrode pins of the atomizer core 61 are electrically connected to the control circuit board 72; then, the battery 71 can be electrically connected to the control circuit board 72 by means of a wire, and the battery 71 is placed adjacent to the liquid storage cup 5; then, the lower end of the body shell 1 (i.e., the second end 1) is connected by a snap connection. 2) Securely engage the second annular inner cover portion 31 of the bottom cover 3, so that the liquid storage cup 5 and battery 71 are both located within the body shell 1. The flexible display assembly 8 can then be electrically connected to the control circuit board 72 via a flexible flat cable. The protective shell 9 is then fitted over the outer periphery of the body shell 1 from the upper end (i.e., the first end 11) of the body shell 1, with the second edge protrusion 92 at the lower end of the protective shell 9 inserted into the second groove 30 of the bottom cover 3. Finally, the top cover 2, which is connected to the suction nozzle 4, is securely engaged with the upper end of the body shell 1 via a snap-fit ​​connection, with the first edge protrusion 91 at the upper end of the protective shell 9 inserted into the first groove 20 of the top cover 2. This completes the assembly of an aerosol generating device comprising the protective shell 9 and the flexible display assembly 8.

[0113] It should be noted here that other contents of the shell assembly and the aerosol generating device disclosed in this application can be found in the prior art and will not be described in detail here.

[0114] The above are only preferred embodiments of the present application and do not limit the patent scope of the present application. All equivalent structural transformations made based on the contents of the present application specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present application.
