Description

Technical Field

[0001] The present application relates to the technical field of electronic atomization, and more specifically, to a shielding cover assembly and an aerosol generating device. Background Art

[0002] Aerosol generating devices generally generate aerosols by heating an aerosol generating substrate placed therein. The opening for inserting the aerosol generating substrate is not completely open, but is provided with a shielding cover, which needs to be opened during use and closed after use to prevent dust or other objects from entering and keep the interior of the device from being contaminated. In the current design of aerosol generating devices, the shielding cover designed at the opening usually requires the user to manually turn it, such as manually turning it left and right, to open the opening, and after use, the user manually turns it in the opposite direction to close the opening.

[0003] At present, some designs have provided certain assistance in the process of the user manually turning the shielding cover, allowing the user to apply a little force to make the shielding cover deflect a small angle and then automatically fully open and close, which provides certain operational convenience. However, the user still needs to manually operate twice, which is still inconvenient in use. Moreover, if the user forgets to manually operate after use, the auxiliary structure cannot automatically close the shielding cover. Utility Model Content

[0004] The purpose of the embodiments of the present application is to provide a shielding cover assembly, aiming to solve the technical problems that in the existing aerosol generating device, the user still needs to manually open and close the shielding cover when using it, which causes complicated operation and the user easily forgets to close the shielding cover.

[0040] In order to illustrate the technical solution described in this application, a detailed description is given below in conjunction with specific drawings and embodiments.

[0041] See also Figures 1 to 3 As shown, the embodiment of the present application provides an aerosol generating device 200, which includes a shielding cover assembly 100 and a heating element 6. Specifically, as Figure 1 , Figure 2 and Figure 3 As shown, the shielding cover assembly 100 includes a housing 3 and a shielding cover 4. Figure 2 , Figure 3 and Figure 4 As shown, the housing 3 has an inner cavity 30 and an opening 331 communicating with the inner cavity 30, and the shielding cover 4 is rotatably disposed on the inner wall of the opening 331; wherein the shielding cover 4 has a first position and a second position, in which the shielding cover 4 closes the opening 331 (see Figure 1 and Figure 3 In the second position, the shielding cover 4 is flipped to open the opening 331 (see Figure 2 and Figure 4 The heating element 6 is disposed in the inner cavity 30, as shown. Figures 3 to 5 shown.

[0042] When the user uses the aerosol generating device 200, the aerosol generating substrate 9 is inserted into the opened opening 331, and the bottom of the aerosol generating substrate 9 enters, contacts or approaches the heating element 6, and the heating element 6 starts to work and heats the aerosol generating substrate 9. After the user finishes using the aerosol generating device 200, the aerosol generating substrate 9 is pulled out from the opening 331 and the shielding cover 4 is closed.

[0043] See also Figure 2 and Figure 4 As shown, in the embodiment of the present application, in the second position, the shielding cover 4 is designed to be turned inward, that is, turned toward the inner cavity 30, so that the opening 331 is opened. Figure 3 and Figure 4 As shown, the shielding cover assembly 100 also includes a reset member 5, which is arranged on the shielding cover 4, or on the shell 3, or on both the shielding cover 4 and the shell 3, and is used to provide a reset force for the shielding cover 4 to flip from the second position to the first position.

[0044] The shielding cover 4 is designed to flip inward, so that the user can hold the aerosol generating matrix 9, align the lower end of the aerosol generating matrix 9 with the surface of the shielding cover 4, and apply force through the aerosol generating matrix 9 to push the shielding cover 4 to flip downward. In this process, the user does not need to use his hands to make some movements to open the shielding cover 4 in advance, which simplifies the use operation and makes it more convenient and comfortable to use. In addition, after use, the aerosol generating matrix 9 is pulled out, and the shielding cover 4 automatically returns to the first position by the reset force provided by the reset member 5, and the user does not need to manually close the shielding cover 4. In the non-use state, the dustproof performance of the shielding cover 4 is guaranteed. In general, the shielding cover assembly 100 allows the user to operate less and use it more conveniently when using it, and the dustproof performance is stable and reliable.

[0045] It is understood that the shielding cover assembly 100 is not limited to being used in the aerosol generating device 200, and can be used in any scenario where the opening 331 needs to be opened to insert an object and the opening 331 needs to be closed after use. In the above and following descriptions, the aerosol generating device 200 and the inserted object are taken as an example for explanation.

[0046] Please refer to Figures 3 to 5 As shown, in one embodiment, the housing 3 includes a housing body 31, a bracket 32 ​​and a gland 33. The interior of the housing body 31 forms the aforementioned inner cavity 30. One end of the housing body 31 is open-ended to form a port 310 ( Figure 6 The inner cavity 30 is also provided with an electrical structure such as a circuit component 7 electrically connected to the heating element 6. The bracket 32 ​​is fixedly arranged in the inner cavity 30 for carrying the heating element 6, the circuit component 7, etc. The pressure cover 33 is fixed to the upper end of the bracket 32. The pressure cover 33 and the bracket 32 ​​are both annular structures, and the middle space of the two together defines the aforementioned opening 331, see Figure 6 shown.

[0047] The bracket 32 ​​may be integral or split. Figures 3 to 5 As shown in the figure, the bracket 32 ​​includes an upper bracket 321 and a lower bracket 322, and the lower bracket 322 is located on the side of the upper bracket 321 away from the pressure cover 33. The upper bracket 321 is mainly used to support and install the heating element 6 and the pressure cover 33, and the lower bracket 322 is mainly used to support and install the circuit component 7, etc.

[0048] In this embodiment, the shielding cover 4 is rotatably disposed between the pressure cover 33 and the upper end of the bracket 32, that is, between the pressure cover 33 and the upper bracket 321. Figure 6 shown.

[0049] Specifically, Figure 5 and Figure 6As shown, a rotating shaft 45 is formed on the outer surface 401 of the shielding cover 4, and the rotating shaft 45 is limited between the end surfaces of the pressure cover 33 and the upper bracket 321 that are close to each other. In this way, the shielding cover 4 and its rotating shaft 45 are easily installed.

[0050] Please refer to further Figure 5 and Figure 7 As shown, grooves 330 are formed on the end surfaces of the pressure cover 33 and the upper bracket 321 that are close to each other. The cross-sectional shape of the groove 330 is substantially semicircular. The two grooves 330 are opposite to each other in the up-down direction to form an axial hole 34 for installing the rotating shaft 45.

[0051] In one embodiment, see Figure 1 , Figure 3 and Figure 4 As shown, the shielding cover 4 includes a plurality of cover bodies 40, and one side of each cover body 40 is rotatably disposed on the inner wall of the opening 331. In the first position, the side surfaces of the cover bodies 40 abut against each other to form a plate-like structure close to the size of the opening 331, which is used to close the opening 331. Figure 1 and Figure 3 shown.

[0052] like Figure 2 and Figure 3 As shown, in an optional embodiment, the shielding cover 4 includes two independently rotatable cover bodies 40, which are defined as a first cover body 41 and a second cover body 42 respectively.

[0053] Among them, further optionally, the first cover body 41 and the second cover body 42 are generally designed in a mirror-symmetrical manner, and their rotation center axes are parallel to each other. In this case, the first cover body 41 and the second cover body 42 are similar to two flat doors, which can allow the opening 331 to be opened and closed. Please refer to Figure 3 and Figure 4 .

[0054] In one embodiment, the reset member 5 may be an elastic member. When in the second position, the elastic member is compressed by the shielding cover 4, thereby providing a force for flipping the shielding cover 4 toward the first position.

[0055] Specifically, the reset member 5 is a torsion spring, which is arranged on the surface of each cover body 40 facing the inner cavity 30 (hereinafter defined as the inner surface 402, see Figure 3 ) and the surface facing away from the inner cavity 30 (hereinafter defined as the outer surface 401, see Figure 3 As shown), the central axis of the torsion spring is set to be parallel to the rotation center axis of each cover body 40.

[0056] Alternatively, the reset member 5 is a piece of elastic material (such as elastic foam), which is arranged on the inner wall of the housing 3 by bonding or the like, and is compressed by the cover 40 when in the second position.

[0057] The present application also provides an implementation form of a reset member 5, see Figure 3 and Figure 4 As shown, the reset member 5 includes a magnet 53 provided on each cover body 40. Taking two cover bodies 40 as an example, the two magnets 53 are respectively defined as a first magnet 51 provided on the first cover body 41, and a second magnet 52 provided on the second cover body 42; wherein, in the second position, the first magnet 51 and the second magnet 52 are arranged facing each other with different magnetic end faces 50, and in the first position, the first magnet 51 and the second magnet 52 are simultaneously facing the inner cavity 30 or simultaneously facing the outside of the shell 3 with different magnetic end faces 50.

[0058] Therefore, when the aerosol generating substrate 9 is inserted into the opening 331, the two opposite sides of the aerosol generating substrate 9 are different magnetic poles, that is, one is an S pole and the other is an N pole. The magnetic attraction generated between the different magnetic poles can enable the first cover 41 and the second cover 42 to apply a certain clamping force to the aerosol generating substrate 9, see Figure 4 As shown ( Figure 4 The dotted line in the middle indicates the magnetic attraction force), so that the first cover body 41, the second cover body 42 and the aerosol generating matrix 9 can all be stably maintained in place, and the aerosol generating matrix 9 is not likely to shake or fall off.

[0059] When the aerosol generating matrix 9 is extracted, the magnetic attraction force generated between the different magnetic poles can make the first cover body 41 and the second cover body 42 continue to rotate toward each other, that is, the first cover body 41 and the second cover body 42 can rotate outward, and their sides approach each other until they reach the first position, and their sides can approach each other with a minimum gap, such as fitting without a gap, see Figure 3 Furthermore, the outer surface 401 of the first cover 41 (e.g., corresponding to the S pole of the first magnet 51) and the outer surface 401 of the second cover 42 (e.g., corresponding to the N pole of the second magnet 52) ​​always maintain mutual attraction, and the inner surface 402 of the first cover 41 (e.g., corresponding to the N pole of the first magnet 51) and the inner surface 402 of the second cover 42 (e.g., corresponding to the S pole of the second magnet 52) ​​always maintain mutual attraction ( Figure 3 The middle dotted line indicates magnetic attraction), the first cover body 41 and the second cover body 42 can be stably maintained in the first position to keep the opening 331 stably closed.

[0060] Moreover, the design of the reset member 5 has advantages. The magnet 53 is arranged on the cover body 40 instead of the shell 3, which is more convenient for the structural design cost and installation cost of the shielding cover assembly 100. For example, there is no need to reserve additional space for the magnet 53 on the shell 3, and there is no need to design additional installation means on the shell 3. Only the corresponding design of each cover body 40 is required.

[0061] See also Figure 4 As shown, in the second position, the two magnets 53 attract each other with their respective magnetic end faces 50, that is, the magnetic attraction force is generated on the entire magnetic end faces 50 of the magnets 53. If the torque generated by the magnetic attraction forces at different positions on the magnetic end faces 50 on the cover body 40 is symmetrical about the central axis of the rotating shaft 45, then the cover body 40 is likely to remain in the second position, and the tendency to deflect to the first position is relatively small.

[0062] In order to avoid this problem, a solution is provided in which the rotating shaft 45 is offset relative to the center point of the magnetic pole end face 50 of the magnet 53. Figure 4 In the second position shown in , the rotating shaft 45 is located above the center point of the magnetic pole end surface 50, or even above the entire magnet 53. Then, the overall torque of the magnetic attraction force at various locations on the magnetic pole end surface 50 on the rotating shaft 45 is in the left and right directions (for the rotating shaft 45 on the right, the torque is to the left, and for the rotating shaft 45 on the left, the torque is to the right), which easily causes the magnet 53 and the cover body 40 to deflect upward.

[0063] Or, for another solution, please continue to Figure 4 As shown, in the second position, a conical gap 47 is formed between the mutually adjacent magnetic pole ends 50 of the first magnet 51 and the magnet 53 (when the magnetic pole ends 50 are substantially parallel to the outer surface 401 of the cover 40, the conical gap 47 may be present between the outer surfaces 401 of the two covers 40), and the width of the upper end of the conical gap 47 is greater than the width of the lower end. That is, in the second position, the lower ends of the two magnets 53 are closer, and the magnetic attraction generated is greater, so that it is easier to deflect the magnet 53 and the cover 40 upward.

[0064] The above two solutions can be used either one or the other. Figure 4 Used simultaneously as shown in .

[0065] Please refer to Figure 3 and Figure 4 As shown, the first magnet 51 is disposed on the side of the first cover body 41 facing the inner cavity 30, and the second magnet 52 is disposed on the side of the second cover body 42 facing the inner cavity 30. The purpose of such a design is that the first magnet 51 and the second magnet 52 can always be hidden inside the cover body 40, and the user cannot observe the first magnet 51 and the second magnet 52 from any angle regardless of the position, which is conducive to the appearance consistency of the shielding cover assembly 100.

[0066] Specifically, the first magnet 51 can be embedded in the inner surface 402 of the first cover 41, and the second magnet 52 can be embedded in the inner surface 402 of the second cover 42, see Figure 3 , Figure 6 and Figure 7For example, the cover body 40 is fixed in the recessed area 403 of the inner surface 402 of the cover body 40 by interference fit and / or gluing, see Figure 7 shown.

[0067] Alternatively, in more alternative embodiments, in the reset member 5, the inner surface 402 of the cover body 40 and the inner wall of the shell 3 are provided with mutually repelling magnets 53. In the second position, the two magnets 53 are close to each other with the same magnetic poles, so that the repulsive force between the same magnetic poles serves as the reset force of the cover body 40.

[0068] See also Figure 4 As shown, in one embodiment, the shielding cover assembly 100 further includes a magnetic sensor 8 disposed on the inner wall of the housing 3 for detecting changes in the magnetic field of the first magnet 51 and / or the second magnet 52. The magnetic sensor 8 is electrically connected to the circuit assembly 7.

[0069] According to the specific configuration of the shell 3 , the magnetic sensor 8 can be disposed on the inner wall of the shell body 31 , or the inner wall of the lower bracket 322 , or the inner wall of the upper bracket 321 , etc., and only needs to be able to sense the flipping of the cover body 40 .

[0070] In the first position, the magnet 53 is far away from the magnetic sensor 8, and in the second position, the magnet 53 is close to the magnetic sensor 8. Therefore, when the cover 40 changes between the first position and the second position, the magnetic sensor 8 can sense the change of the magnetic field and output a corresponding sensing signal.

[0071] In this embodiment, the magnet 53 in the reset member 5 also serves as a flip-in-place indicator structure for the cover body 40 , which can further simplify the structure and design of the shielding cover assembly 100 .

[0072] In an optional embodiment, since the cover 40 realizes synchronous flipping by the interaction force of the magnet 53, the magnetic sensor 8 is only used to detect the magnetic field change of the first magnet 51 or the second magnet 52, that is, the magnetic sensor 8 is only set corresponding to one of the magnets 53 and the cover 40. Figure 4 This can simplify the wiring between the magnetic sensor 8 and the circuit component 7 and further save the space occupied by the inner cavity 30.

[0073] It should be noted that the aerosol generating device 200 further includes a position detector (not shown) for detecting whether the aerosol generating substrate 9 is inserted in place relative to the heating element 6, and the position detector is connected to the circuit assembly 7. When the magnetic sensor 8 senses a signal (referring to a signal that the cover 40 is opened), the position detector is controlled to turn on the power supply, and the position detector can be used to sense the insertion of the aerosol generating substrate 9. When the position detector detects that the aerosol generating substrate 9 is inserted in place, a corresponding position signal is sent to the circuit assembly 7, and the circuit assembly 7 controls the heating element 6 to turn on the power supply and start working.

[0074] See also Figure 1 As shown, in one embodiment, a first guide recess 410 is formed on the outer surface 401 of the first cover body 41 near the edge, and the first guide recess 410 gradually deepens in the direction toward the second cover body 42; a first guide recess 410 is formed on the outer surface 401 of the second cover body 42 near the edge, and the second guide recess 420 gradually deepens in the direction toward the first cover body 41.

[0075] The first guide recess 410 and the second guide recess 420 are interconnected to form a funnel-shaped guide groove 404. The guide groove 404 is used to provide a certain guide effect when the aerosol generating substrate 9 pushes the shielding cover 4, so as to facilitate the insertion of the aerosol generating substrate 9, and can also provide certain instructions and guidance to the user.

[0076] Please refer to Figure 3 , Figure 6 and Figure 7 As shown, the upper bracket 321 is provided with a limiting surface 3210, and in the first position, the inner surface 402 of the shielding cover 4 partially abuts against the limiting surface 3210. That is, the first position of the shielding cover 4 is its limit position, and the cover body 40 cannot continue to flip outward, which can further ensure the stability of the cover body 40 in the first position.

[0077] like Figure 7 As shown, the rotation axis 45 of the cover body 40 is located in a region outside the limiting surface 3210 , which can avoid the interference of the limiting surface 3210 on the rotation of the cover body 40 .

[0078] Please refer to Figure 4 and Figure 6 As shown, in one embodiment, the heating element 6 is disposed around the lower section of the aerosol generating substrate 9, and the heating element 6 can directly heat the aerosol generating substrate 9. The heating element 6 can transfer heat to the aerosol generating substrate 9 by heat conduction, or can transfer heat radiation energy to the aerosol generating substrate 9 by heat radiation, thereby achieving the purpose of heating the aerosol generating substrate 9.

[0079] In more optional embodiments, the heating element 6 can be replaced by being arranged below the aerosol generating substrate 9 to heat the aerosol generating substrate 9. Alternatively, the heating element 6 can also be inserted into the lower section of the aerosol generating substrate 9 to heat the aerosol generating substrate 9.

[0080] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
