Description

Technical Field

[0002] An aerosol generating device is a small device that can use heat not burn (HNB) technology to act on an aerosol generating substrate and generate an aerosol. Specifically, the aerosol generating device usually heats the aerosol generating substrate to a temperature that can generate an aerosol but is not high enough to burn, so that the aerosol generating substrate can generate an aerosol for the user to inhale without burning. The aerosol generating device can ensure the original taste of the aerosol generating substrate and effectively control the production of harmful substances. As people pay more and more attention to their health, aerosol generating devices have gradually become people's first choice.

[0033] In order to prevent foreign matter from falling into the aerosol generating device and generating harmful substances that may affect human health when heated, the aerosol generating device is usually provided with a cover and a driving component that drives the cover to open and close the loading hole. However, the current driving component is only used to drive the cover to open and close the loading hole, and the function of the driving component is relatively simple. In order to solve this problem, the embodiment of the present application provides an aerosol generating device 100 ( Figure 1 shown).

[0034] See also Figures 1 to 4 The aerosol generating device 100 according to an embodiment of the present application includes a housing 10, a drive assembly 30, and a cover assembly 50. The housing 10 is provided with a loading hole 11 for loading an aerosol-generating substrate therein. The drive assembly 30 is mounted on the housing 10 and includes a drive member 31 having a through hole 311 and a first mating member 313. The drive member 31 is disposed around the loading hole 11 and is rotatable relative to the housing 10 to assume a first state, a second state, and a third state. The cover assembly 50 is installed on the shell 10, and the cover assembly 50 includes a connected cover 51 and a second mating piece 53. The second mating piece 53 cooperates with the first mating piece 313 to enable the driving member 31 to drive the cover 51 to rotate relative to the shell 10; wherein, when the driving member 31 is in the first state, the cover 51 covers the loading hole 11; when the driving member 31 is in the second state, the cover 51 opens the loading hole 11, and the aerosol generating device 100 is in the first operating mode; when the driving member 31 is in the third state, the aerosol generating device 100 is in the second operating mode, and the first operating mode and the second operating mode are different.

[0035] Specifically, the aerosol-generating device 100 is a structure capable of generating an aerosol by heating an aerosol-generating substrate. The aerosol may be visible or invisible and may include vapor (e.g., fine particulate matter in a gaseous state, which is typically liquid or solid at room temperature) as well as liquid droplets of gas and condensed vapor. The aerosol-generating substrate is a product that has been processed and heated to produce an aerosol. The aerosol-generating substrate may be in a liquid state, a fully solid state, or a semi-solid state. When the aerosol-generating substrate is liquid, the liquid aerosol-generating substrate is a mixed liquid containing substances such as nicotine and nicotine dissolved therein, and its solutes may be common organic and / or inorganic solutes such as propylene glycol, vegetable glycerin, and pure water. When the aerosol-generating substrate is fully solid, the aerosol-generating substrate may be prepared using processes such as rolling, slurrying, die casting, and extrusion. The aerosol-generating substrate may be a cylindrical structure similar to a cigarette, or may be a sheet, strip, or block structure. The aerosol generating substrate of the present application is a cylindrical structure similar to a cigarette.

[0036] See also Figure 1 and Figure 2 The housing 10 is used to house other components of the aerosol generating device 100, such as the drive assembly 30, the cover assembly 50, and the heating assembly of the aerosol generating device 100. The housing 10 is also used to hold the aerosol-generating substrate. To use the aerosol generating device 100, the user can load the aerosol-generating substrate into the loading hole 11. The aerosol generating device 100 then activates the heating mode, heating the aerosol-generating substrate to generate an aerosol for the user to inhale.

[0037] See also Figure 2 and Figure 3 The driving component 30 is mounted on the top of the housing 10. The driving component 30 is used to drive the cover 51 to rotate relative to the housing 10 so that the cover 51 can cover the loading hole 11. The driving member 31 is mounted on the housing 10. The driving member 31 can rotate relative to the housing 10 when subjected to external force. The through hole 311 of the driving member 31 corresponds to and is connected to the loading hole 11 of the housing 10. When the aerosol generating substrate is loaded into the aerosol generating device 100, the aerosol generating substrate first passes through the through hole 311 and enters the loading hole 11. Preferably, the cross-sectional area of the through hole 311 can be greater than or equal to the cross-sectional area of the loading hole 11, thereby facilitating the aerosol generating substrate to pass through the through hole 311 and enter the loading hole 11. The first mating piece 313 is used to cooperate with the second mating piece 53 of the cover assembly 50. When the driving piece 31 is rotated relative to the shell 10 by an external force, the first mating piece 313 can drive the second mating piece 53 to rotate, so that the second mating piece 53 can drive the cover 51 to rotate relative to the shell 10.

[0038] See also Figure 2 and Figure 4 The cover assembly 50 is mounted on the top of the housing 10. The cover assembly 50 is used to cover the loading hole 11 when the user is not using the aerosol generating device 100, so as to prevent foreign matter from falling into the loading hole 11 and generating harmful substances after being heated, thereby affecting the user's puffing experience and even endangering human health.

[0039] The cover 51 can rotate relative to the housing 10 to cover or open the through-hole 311. When the cover 51 covers the through-hole 311, it can cover the loading hole 11, thereby preventing foreign matter from passing through the through-hole 311 and falling into the loading hole 11. When the cover 51 opens the through-hole 311, it can open the loading hole 11, allowing the aerosol-generating substrate to pass through the through-hole 311 and enter the loading hole 11. The second mating member 53 is connected to the housing 10, and the cover 51 is connected to the second mating portion 3133. When the first mating portion 3131 drives the second mating portion 3133 to rotate, the second mating portion 3133 can drive the cover 51 to rotate relative to the housing 10. The cover 51 and the second mating member 53 can be a one-piece structure or a separate structure. When the cover 51 and the second mating member 53 are a one-piece structure, the cover 51 and the second mating member 53 can be integrally formed, which simplifies the processing steps of the cover assembly 50. When the cover 51 and the second fitting 53 are separate structures, the cover 51 and the second fitting 53 can be detachably or non-detachably connected. Removable installation methods include, but are not limited to, threaded connections, screw connections, or snap connections. Non-detachable installation methods include, but are not limited to, welding, gluing, or interference fit.

[0040] The cover 51 may include a main body 511 and a connecting portion 513. The connecting portion 513 has opposite ends connected to the second mating member 53 and the main body 511, respectively. The main body 511 is used to cover or open the through-hole 311. When the driving member 31 rotates relative to the housing 10, the first mating member 313 drives the second mating member 53 to rotate. The second mating member 53, via the connecting portion 513, drives the main body 511 to rotate relative to the housing 10 to cover or open the through-hole 311. The area of the main body 511 may be greater than or equal to the cross-sectional area of the through-hole 311. When the main body 511 covers the through-hole 311, foreign matter is unlikely to enter the loading port 11 through the through-hole 311.

[0041] In one embodiment, the first operating mode and the second operating mode may be heating modes (heating gears) of the aerosol generating device 100. The heating efficiency in the first operating mode is different from the heating efficiency in the second operating mode. For example, the heating efficiency of the aerosol generating device 100 in the first operating mode may be less than the heating efficiency of the aerosol generating device 100 in the second operating mode. In another embodiment, the aerosol generating device 100 may display the power level in the first operating mode, and the aerosol generating device 100 may display both the power level and the heating temperature in the second operating mode. This application is described as an example in which the first operating mode and the second operating mode are both heating modes of the aerosol generating device 100.

[0042] Please combine Figure 4 and Figure 6 , when the driving member 31 is in the first state ( Figure 4 As shown in FIG, the first matching member 313 cooperates with the second matching member 53 so that the cover 51 can cover the through hole 311, thereby preventing foreign matter from entering the loading hole 11 through the through hole 311. When the user needs to use the aerosol generating device 100, the user applies an external force to the driving member 31 so that the driving member 31 can rotate a certain angle along the first direction X. At this time, the driving member 31 can be switched to the second state ( Figure 5 (as shown). The first mating member 313 and the second mating member 53 cooperate to rotate the cover 51, opening the through-hole 311. The aerosol-generating substrate can then be loaded into the loading hole 11 through the through-hole 311. Upon detecting that the driving member 31 is in the second state, the aerosol-generating device 100 can be in the first operating mode, thereby heating the aerosol-generating substrate in the loading hole 11 to generate an aerosol for inhalation by the user. Once the aerosol-generating substrate enters the loading hole 11, the first operating mode is activated to heat the aerosol-generating substrate, eliminating the need for the user to adjust the heating mode. This simplifies operation and provides a better user experience.

[0043] The user continues to apply external force to the driving member 31, so that the driving member 31 continues to rotate a certain angle along the first direction X. At this time, the driving member 31 switches to the third state ( Figure 6 As shown). At this time, the cover 51 may not rotate or continue to rotate relative to the housing 10, and the cover 51 may remain in the position of the open through-hole 311. When the driving member 31 is detected to be in the third state, the aerosol generating device 100 can switch from the first operating mode to the second operating mode, so that the aerosol generating matrix in the loading hole 11 can be heated to generate an aerosol for the user to inhale. The driving member 31 can not only drive the cover 51 to open and cover the through-hole 311, but also adjust the heating mode of the aerosol generating matrix. The aerosol generating device 100 does not need to be additionally provided with a structure for adjusting the heating mode, and the structure of the aerosol generating device 100 is relatively simple.

[0044] The first operating mode can be a standard heating mode, in which the aerosol-generating matrix can be evenly heated at an appropriate temperature, stably generating aerosols and providing users with a balanced puffing experience. The second operating mode can be a Boost heating mode (enhanced heating mode), in which the aerosol-generating matrix is heated to a higher temperature and at a faster heating rate, resulting in a higher concentration of aerosol generated per unit time. Users can select the first or second operating mode as needed. Switching between the two heating modes requires only rotating the drive member 31, making operation simple and providing a better user experience.

[0045] In the aerosol generating device 100 of the embodiment of the present application, when the driving member 31 is in the first state, the first mating member 313 and the second mating member 53 cooperate to enable the cover 51 to cover the loading hole 11. When the driving member 31 is in the second state, the first mating member 313 and the second mating member 53 cooperate to enable the cover 51 to rotate relative to the housing 10 to open the loading hole 11, and the aerosol generating substrate can enter the loading hole 11 through the through hole 311. At the same time, the aerosol generating device 100 can be in the first operating mode. When the driving member 31 is in the third state, the cover 51 opens the loading hole 11, and the aerosol generating device 100 can be in the second operating mode. The first operating mode and the second operating mode are different, and the user can select the corresponding operating mode according to needs. The driving member 31 of the present application can not only drive the cover 51 to open and cover the loading hole 11, but also adjust the operating mode of the aerosol generating device (first operating mode and second operating mode). The driving assembly 30 has many functions, and the aerosol generating device 100 does not need to be provided with other components to adjust its operating mode. The structure of the aerosol generating device 100 is relatively simple.

[0046] In addition, in one example, the driving member 31 rotates relative to the housing 10 around the axis of the loading hole 11 .

[0047] The aerosol generating device 100 will be further described below with reference to the accompanying drawings.

[0048] See also Figure 2 and Figure 3 In some embodiments, a mounting cavity 13 is provided at the top of the housing 10, and the drive assembly 30 and the cover assembly 50 are both located in the mounting cavity 13; the housing 10 is also provided with a protrusion 15, which extends from the inner wall of the loading hole 11 toward the mounting cavity 13, and the drive member 31 is mounted on the protrusion 15 through the through hole 311 and can rotate relative to the protrusion 15.

[0049] The mounting cavity 13 is used to mount the drive assembly 30, the cover assembly 50, and other components of the aerosol generating device 100. The protrusion 15 is an annular structure surrounding the loading hole 11. When the drive member 31 is sleeved on the protrusion 15, the protrusion 15 can serve to mount and limit the drive member 31. When the drive member 31 is subjected to external force, the drive member 31 can rotate relative to the housing 10 with the protrusion 15 as the axis. During the rotation, the drive member 31 can switch between a first state, a second state, and a third state. When the drive member 31 is sleeved on the protrusion 15, the installation method of the drive member 31 is relatively simple, and the structure of the aerosol generating device 100 is relatively compact. Compared with the method of arranging the drive member 31 and the protrusion 15 side by side, the horizontal space at the top of the aerosol generating device 100 is saved, making it easier to arrange functional devices such as light-emitting elements on the top, which is conducive to the miniaturization design of the aerosol generating device 100.

[0050] Please combine Figures 4 to 6 Specifically, in some embodiments, the outer wall of the protrusion 15 is provided with a first limiting portion 151, a second limiting portion 153 and a third limiting portion 155 spaced apart from each other; the driving assembly 30 also includes a limiting member 33, which is provided on the driving member 31 and can rotate relative to the housing 10 together with the driving member 31; wherein the limiting member 33 cooperates with the first limiting portion 151 to place the driving member 31 in the first state, the limiting member 33 cooperates with the second limiting portion 153 to place the driving member 31 in the second state, and the limiting member 33 cooperates with the third limiting portion 155 to place the driving member 31 in the third state.

[0051] The first limiting portion 151, the second limiting portion 153, and the third limiting portion 155 of the present application are all grooves that are recessed from the outer wall of the protrusion 15 toward the inner wall of the protrusion 15. At least a portion of the limiting member 33 protrudes from the inner wall of the driving member 31 toward the protrusion 15. When the limiting member 33 engages with one of the first limiting portion 151, the second limiting portion 153, and the third limiting portion 155, the driving member 31 can be restricted in its current state. When the aerosol generating device 100 is moved, the driving member 31 is unlikely to shake or rotate. When a user applies a certain external force to the driving member 31, the driving member 31 can rotate relative to the protrusion 15 until the limiting member 33 engages with another of the first limiting portion 151, the second limiting portion 153, and the third limiting portion 155, at which point the driving member 31 stops rotating.

[0052] The driving member 31 may be provided with a second hole 317, and the limiting member 33 may be fixedly mounted in the second hole 317. The limiting member 33 may include a main body, an elastic portion, and a protrusion. The elastic portion may have a certain elastic force. The protrusion protrudes from the inner wall of the driving member 31 toward the protrusion 15 and is configured to engage with the first limiting portion 151, the second limiting portion 153, or the third limiting portion 155. When the driving member 31 rotates relative to the protrusion 15, the protrusion engages with the outer wall of the protrusion 15, compressing the elastic portion and causing the protrusion to retract away from the protrusion 15. When the protrusion corresponds to one of the first limiting portion 151, the second limiting portion 153 and the third limiting portion 155, the elastic portion returns to its initial shape, and the elastic portion drives the protrusion to extend toward the direction close to the protruding portion 15, so that the protrusion can extend into the groove (the first limiting portion 151, the second limiting portion 153 or the third limiting portion 155). The protrusion cooperates with the groove, so that the driving member 31 can be stably in the current state.

[0053] When the user applies external force to the driving member 31 to rotate the driving member 31, after the stopper 33 switches from engaging with the first stopper 151 to engaging with the second stopper 153, the user will feel a certain resistance when continuing to rotate the driving member 31. Therefore, the user knows that the stopper has entered the second stopper 153 and can stop applying force to the driving member 31. The user can know the current status of the driving member 31 in real time, which provides a better user experience.

[0054] Preferably, the protrusion 15 of the present application is provided with two first limiting portions 151, two second limiting portions 153, and two third limiting portions 155. A first limiting portion 151, a second limiting portion 153, and a third limiting portion 155 constitute a group, and the two groups of limiting portions are symmetrically distributed on the protrusion 15. Two limiting members 33 are also provided, and the two limiting members 33 are symmetrically distributed on the driving member 31. One limiting member 33 cooperates with one group of limiting portions, and the other limiting member 33 cooperates with the other group of limiting portions. This ensures that the driving member 31 rotates more smoothly and is less likely to wobble during rotation.

[0055] See also Figure 2 and Figure 3 In some embodiments, a first detection member 17 is provided on the shell 10; the driving assembly 30 also includes a second detection member 35, which is installed on the driving member 31 and can rotate relative to the shell 10 with the driving member 31. The second detection member 35 cooperates with the first detection member 17 to detect the current state of the driving member 31.

[0056] Please combine Figures 4 to 6Specifically, in some embodiments, the first detection members 17 include two, and the two first detection members 17 are spaced apart. When the driving member 31 is in the second state, the second detection member 35 cooperates with one of the first detection members 17. When the driving member 31 is in the third state, the second detection member 35 cooperates with the other first detection member 17.

[0057] Among them, the driving member 31 is provided with a first hole 315, and the second detection member 35 can be fixedly installed in the first hole 315. The two first detection members 17 of the present application are both Hall sensors, and the second detection member 35 can be a magnet. When the driving member 31 switches from the first state to the second state, in the length direction H of the aerosol generating device 100, the second detection member 35 corresponds to a first detection member 17. After the Hall sensor (first detection member 17) detects the first signal of the magnet, the Hall sensor can transmit the first signal to the controller. The controller can control the heating component of the aerosol generating device 100 to be in the first operating mode, and the controller can also transmit the first signal to the display screen of the aerosol generating device 100, so that the display screen can display that the current driving member 31 is in the second state and the current heating mode is in the first operating mode. The user can intuitively know the current state and heating mode of the driving member 31 through the display screen, and the user's experience is better.

[0058] When the driving member 31 rotates relative to the housing 10 to switch from the second state to the third state, in the height direction of the aerosol generating device 100, the second detection member 35 corresponds to the other first detection member 17. After the Hall sensor (first detection member 17) detects the second signal of the magnet, the Hall sensor can transmit the second signal to the controller. The controller can control the heating component of the aerosol generating device 100 to be in the second operating mode, and the controller can also transmit the second signal to the display screen of the aerosol generating device 100, so that the display screen can display that the current driving member 31 is in the second state and the heating mode is in the second operating mode. The user can intuitively know the current state of the driving member 31 and the heating mode through the display screen, and the user's experience is better.

[0059] The first detection member 17 cooperates with the second detection member 35 to detect the current state of the driver 31, and adjusts the corresponding heating mode according to the current state of the driver 31. The activation and switching of the heating mode of the aerosol generating device 100 is relatively simple, and the user experience is good.

[0060] See also Figure 2 、 Figure 3 、 Figure 5 and Figure 6In some embodiments, a mating column 18 is provided on the housing 10, and a mating groove 37 is provided on the driving member 31. The mating column 18 extends into the mating groove 37, and the mating column 18 cooperates with the mating groove 37 to limit the maximum rotation angle of the driving member 31.

[0061] When the engaging post 18 engages with the engaging groove 37, during the rotation of the driving member 31, the limiting member 33 can engage with the first limiting portion 151, the second limiting portion 153, or the third limiting portion 155, and the first engaging member 313 and the second engaging member 53 can engage with each other, thereby preventing the driving member 31 from rotating at an excessively large angle, which would result in the second engaging member 53 being unable to engage with the first engaging member 313. The engaging groove 37 can be an arcuate groove, preferably, with the center of the arcuate groove being at the same position as the center of the cross section of the protrusion 15. When the driving member 31 rotates around the protrusion 15, the engagement of the engaging post 18 and the engaging groove 37 can also guide the rotation of the driving member 31, thereby ensuring a relatively stable rotation of the driving member 31 and further preventing the driving member 31 from shaking relative to the housing 10.

[0062] See also Figures 4 to 6 In some embodiments, the first mating part 313 includes a first mating portion 3131 and a second mating portion 3133, the first mating portion 3131 is provided with at least two teeth, and the second mating part 53 is a gear; when the first mating portion 3131 corresponds to the second mating portion 53, the first mating portion 3131 is engaged with the second mating portion 53 to drive the driving member 31 to rotate relative to the shell 10, and when the second mating portion 3133 corresponds to the second mating portion 53, the second mating portion 3133 is spaced from the second mating portion 53.

[0063] With the cover 51 covering the through-hole 311 and the driver 31 in the first state, when the driver 31 is rotated in the first direction X by an external force, the first engaging portion 3131 engages with the second engaging portion 53, allowing the second engaging portion 53 to rotate in the second direction Y. The first direction X is opposite to the second direction Y, so that the second engaging portion 53 can drive the cover 51 to rotate in the second direction Y to open the through-hole 311. At this point, the driver 31 switches to the second state. After the cover 51 opens the through-hole 311, the second engaging portion 3133 corresponds to the second engaging portion 53. The second engaging portion 3133 lacks teeth, and thus the second engaging portion 3133 is spaced apart from the second engaging portion 53. When the driver 31 rotates relative to the housing 10 to switch to the third state, the first engaging portion 313 does not drive the second engaging portion 53 to rotate, thereby maintaining the cover 51 in its current position and preventing the cover 51 from rotating. At this time, the cover body 51 occupies less space during the rotation process, and other components can be arranged in the installation cavity 13, so the structure of the aerosol generating device 100 is more compact.

[0064] See also Figure 2 、 Figure 4 、 Figure 5 and Figure 6 In some embodiments, a mounting member 19 is further provided on the shell 10, and the second matching member 53 is sleeved on the mounting member 19 and can drive the cover body 51 to rotate relative to the mounting member 19; the cover body assembly 50 also includes a damping member 55, which is sleeved on the mounting member 19 and supports the inner wall of the second matching member 53. The damping member 55 is used to increase the resistance of the second matching member 53 during the rotation process.

[0065] The mounting member 19 is installed in the mounting cavity 13 and is used to mount the cover assembly 50. When the second mating portion 3133 corresponds to the second mating member 53, the second mating member 53 is not restricted by the first mating member 313. The second mating member 53 can easily cause the cover 51 to shake or rotate horizontally, which can easily damage the cover 51 and cause it to collide with other components, causing damage to them. The present application provides a damping member 55 between the mounting member 19 and the second mating member 53 to limit the horizontal rotation of the second mating member 53, thereby preventing the cover assembly 50 from shaking or rotating. The damping member 55 can be a spring, which is mounted on the mounting member 19 and the second mating member 53 is mounted on the spring. When the spring is compressed along the longitudinal direction H of the aerosol generating device 100, it expands radially, thereby resisting the inner wall of the second mating member 53 to prevent the second mating member 53 from rotating horizontally.

[0066] See also Figure 7 In other embodiments, the first mating member 313 includes at least two teeth, the second mating member 53 is a gear, and the first mating member 313 meshes with the second mating member 53 to drive the driving member 31 to rotate relative to the housing 10.

[0067] The first engaging member 313 has a plurality of teeth evenly distributed thereon. When the cover 51 covers the through-hole 311 and the driver 31 is in the first state, when the driver 31 is rotated in the first direction X by an external force, the first engaging member 313 engages with the second engaging member 53, and the second engaging member 53 can rotate in the second direction Y. This allows the second engaging member 53 to drive the cover 51 to rotate in the second direction Y to open the through-hole 311, at which point the driver 31 switches to the second state. After the cover 51 opens the through-hole 311, when the driver 31 rotates relative to the housing 10 to switch to the third state, the first engaging member 313 continues to engage with the second engaging member 53, and the cover 51 continues to rotate in the second direction Y, with the cover 51 still opening the through-hole 311. In this case, the cover 51 occupies a larger space during rotation, which is suitable for situations where there is ample space within the mounting cavity 13.

[0068] See also Figure 1 and Figure 2Furthermore, in some embodiments, the aerosol generating device 100 also includes a shielding cover 70, which is installed on the top of the shell 10, and the driving assembly 30 and the cover assembly 50 are located between the shell 10 and the shielding cover 70. The shielding cover 70 is provided with a through hole 71, and the through hole 71 is connected to the loading hole 11 through the through hole 311. The side wall of the shell 10 and the shielding cover 70 together form a notch 73, and at least part of the driving member 31 is exposed from the notch 73.

[0069] Among them, the shielding cover 70 can play a protective role for the components in the installation cavity 13, and the shielding cover 70 can also play a decorative role, so that the overall aesthetics of the aerosol generating device 100 is better. The cross-sectional area of the perforation 71 can be greater than or equal to the cross-sectional area of the through hole 311. When the aerosol generating matrix is loaded into the aerosol generating device 100, the aerosol generating matrix passes through the perforation 71 and the through hole 311 and enters the loading cavity. When the cover body 51 blocks the through hole 311, the cover body 51 can block the communication between the perforation 71 and the through hole 311, thereby preventing foreign matter from entering the through hole 311 through the perforation 71. The notch 73 is used to expose at least part of the driving member 31, so as to facilitate the user to apply external force to the driving member 31 so that the driving member 31 can rotate relative to the shell 10.

[0070] When the shielding cover 70 is mounted on the housing 10, the shielding cover 70 and the housing 10 can jointly limit the displacement of the driving member 31 in the longitudinal direction H of the aerosol generating device 100. In addition, the shielding cover 70 can also compress the damping member 55 (spring), so that the damping member 55 can expand radially to resist the inner wall of the second fitting member 53, thereby preventing the second fitting member 53 from rotating in the horizontal direction.
